Description

Self-unloading carriage with frame turned on one's side in

Technical Field

The invention relates to a self-discharging carriage structure, in particular to a self-discharging carriage with a frame turned on one's side.

Background

The dumper is an advanced transport vehicle for transporting bulk powder and particle cargoes. The dump truck is usually provided with a semi-trailer train consisting of a semi-trailer and a semi-trailer traction vehicle, various chassis vehicles, a self-unloading loaded bicycle and the like, is particularly suitable for middle and short-distance road transportation, and is a main transportation tool in a bulk powder particle cargo transportation vehicle, and has particular advantages when other vehicles can not realize self-unloading of cargoes.

Dump trucks are numerous in variety and have various classification modes. It can be said that the dump truck can cover almost all products with the same loading structure as the common truck and the special truck due to the advantage of the function, the dump truck greatly expands the application range of the truck, and other types of vehicles are far less than the dump truck, which is the reason that the dump truck takes the dominant role in the transport truck.

Dumpers have wide demands and remarkable advantages in transportation and unloading of granular (e.g., coal slime, grains, engineering materials such as sand, stone and soil) and other types of cargoes. In the specific self-unloading setting, the aspects of unloading safety, unloading efficiency, simple operation, high automation degree, small personnel health/danger coefficient, cost saving, service life of a self-unloading setting mechanism, practical application specification and the like are all the common problems to be solved in the freight transportation field for a long time.

The existing self-unloading device is generally divided into three common modes of side turning (unilateral unloading), back turning and middle turning (bilateral unloading), and the three designs also respectively meet different requirements. The side turning is mainly aimed at one side of a storage yard where cargoes need to be unloaded, for example, coal cargoes need to be unloaded in a floor drain; the middle turning provides a double-side unloading mode, and the track through which the vehicle passes is the middle of two stacks of cargoes; and then the turnup is usually directly connected with the fixed-width discharge opening. First, the smooth departure of the vehicle after the unloading is completed is also a matter of consideration when designing the dump mechanism. Secondly, the freight unloading place is often not a flat and tamped station or road surface, but is often complex and changeable in case of uneven ground or loose ground. In practical application process for many years, because the whole carriage body of the large-sized freight car carriage body fully loaded with a large weight (for example, tens of tons) is deviated during rollover, only one bottom edge (or a tire on the side) of the unloading side is taken as a fulcrum, the proportion of rollover safety accidents of the whole car/carriage caused by rollover self-unloading is far higher than that of other unloading modes, and huge property and personnel losses are brought. In addition, due to the problem of poor balance force of the single fulcrum design, the service life of the side-turning type product is relatively short.

In recent years, manufacturers of these particulate material transportation demands are more willing to purchase dump products with a middle or rear turn, and in heavy-load dump products, the carriage side turn design is in a trend of being gradually eliminated. However, as mentioned above, due to the limitation of some places or unloading demands, people have to use side-turning self-unloading, and have to bear corresponding safety accident risks, which are very huge in personnel and property losses.

Disclosure of Invention

Aiming at the existing situation, because of the continuous existence of single-side unloading demands, the invention changes the conception mode of the original side-turning type self-discharging carriage, and provides a self-discharging carriage with a side-turning type frame, which has a top-opening type carriage structure, and an automatic or manual tarpaulin system can be additionally arranged at the top of the carriage to solve the problem of sprinkling. Meanwhile, the self-unloading carriage structure integrates the fixed underframe and the side beam of the stable bearing type bottom frame with the semi-trailer frame or the upper auxiliary frame of the self-unloading carriage chassis, and drives the lifting cylinder to lift the inner tipping bucket in the carriage frame in a mode of hydraulic pressure, pneumatic pressure or other modes, so that the single-side self-unloading of the goods is realized, and the problems of difficult unloading, high energy consumption, high potential safety hazard and the like are solved. The invention relates to a self-unloading carriage with a side-turned frame, which effectively solves the defects and problems of the existing transportation of powder and particle goods such as coal, expands the functions of vehicles and is a novel single-side self-unloading structure. The invention has the advantages of more reasonable and simple design of each part, less and safer gravity center deviation, better compartment body strength and stronger applicability when the vehicle is unloaded, can reduce the gravity center of the vehicle, enhance the overall strength of the compartment and the like, and the fixed boundary beam can also play a role in diversion and sealing when the vehicle is unloaded.

Specifically, the invention provides a self-unloading carriage with a frame turned on one's side, which mainly comprises: the side sill comprises an underframe, a side sill and at least one inner tipping bucket. Wherein, the underframe and the side beams form a bearing type bottom frame structure of the carriage (the side beams form long edges of the bottom surface of the carriage); the inner tipping bucket can rotate along one side (unloading side) side beam to realize self-unloading, and is arranged on the bottom frame to bear goods when not lifted. Wherein the varus hopper has a floor (when not lifted) as a body floor of the car for carrying cargo and a side stop (when not lifted) as at least a portion of a side stop (lifting/non-unloading) of the car.

One side (edge) of the bottom plate is rotationally connected with a side beam through a turnover pin shaft so as to rotate along the side beam; the other side (edge) of the bottom plate is connected with a side block and is lifted (lifting side) during lifting. Thus, the bottom plate and the side stops form an inner tipping bucket with an L-shaped cross section which is turned over in the carriage frame.

Further, the inner tipping bucket is also provided with at least one oblique pull beam or at least one triangle.

Wherein the diagonal beams are used to connect the bottom plate and the side rails (preferably, the distal/distal ends of the two) for supporting the two. The two cable-stayed beams are preferably two, and are respectively connected with the cross sections of the front end and the rear end of the inner tipping bucket; there may be a plurality of: one or more pieces are arranged on the same section or one or more pieces are respectively arranged on different sections of the inner tipping bucket.

Wherein the triangle is used for connecting one side edge (front end or rear end section) of the bottom plate and the side block, and is used for supporting/closing at least one part of end face of the L-shaped groove formed by the bottom plate and the side block, thereby forming a triangle inner tipping bucket together with the bottom plate and the side block.

Most preferably, the diagonal draw beams, the edges of the floor, the edges of the side rails and/or the (unattached) edges of the triangle, which are located on the front or rear end cross-section (i.e., the edges connecting the floor and the side rails), are also configured to move substantially against the fixed portion of the car body (e.g., the frame, the front rail, the rear rail, the intermediate rail, etc.) during lifting to act as/accomplish a scraper and at the same time prevent leakage of cargo.

In view of the total weight of the box body, it is more preferable that a diagonal girder connecting the distal ends and the distal ends of each inner dump box is respectively arranged at the sections of the front end and the rear end of each inner dump box. From the viewpoint of structural stability and prevention of particle leakage, triangular plates that close the entire L-shaped cross section of the inner dump box, or at least the entire (edge) length of the bottom plate, are more preferable.

Preferably, the carriage of the present invention further comprises at least one intermediate partition dividing the carriage into two or more independent compartments, depending on the overall length of the carriage involved; each bin is provided with an inner tipping bucket provided by the invention. Likewise, adjacent two varus hoppers are preferably separated by an intermediate partition. For the example of the internal turning bucket adopting the triangular plates with the whole L-shaped section for sealing the internal turning bucket, a middle partition plate (consideration of the weight of the car body) is not required to be arranged between the adjacent internal turning buckets, and the two triangular plates which are arranged in a bonding way are mutually scraping plates.

Further, the car also comprises a lifting mechanism for rotational lifting of the dump box (relative to the frame/bottom frame). Of course, the varus bucket may be lifted by other external mechanisms (e.g., a lifting mechanism).

Preferably, the lifting mechanism is a lifting cylinder, and the lifting cylinder is respectively connected with the inner tipping bucket and the bottom frame (such as a side beam and a bottom frame cross beam) and is used for lifting the inner tipping bucket, and lifting the inner tipping bucket by means of hydraulic pressure, air pressure or other modes. At least one, preferably two, lifting cylinders are arranged for each varus bucket, one on the front side and one on the rear side of the dump bucket (in the length direction).

More preferably, the lift cylinder may be mounted on the inner dump bucket or on the bottom frame. And the lifting cylinder is arranged in a side-mounted or middle-mounted manner. The side lifting cylinder is arranged close to one side (lifting side) of the side baffle in the width direction of the carriage; the middle lifting cylinder is arranged at the middle position (the middle part of the underframe).

Further, the varus hopper is provided with chambers/shields (arranged according to the number of lifting cylinders) which isolate the lifting cylinders from the cargo, open towards the bottom frame, and house the lifting cylinders. The chamber is mainly intended for accommodating a lifting cylinder mounted on the inner dump box, but of course also for accommodating a piston rod of the lifting cylinder. Preferably, the chambers are provided on the front and rear sides of the inner dump box. Or the lifting cylinder can also be arranged outside the carriage body (such as outside the front baffle, the rear baffle and the side baffle), and the inner tipping bucket (such as the upper part of the side baffle) is pulled in a lifting manner or connected with the outer wall of the inner tipping bucket (the side baffle) to push the lifting of the inner tipping bucket.

Further, the bottom plate of the varus hopper is also provided with a bottom beam with an inverse U-shaped structure, the bottom beam is matched with the cross beam of the underframe, and the inverse U-shaped bottom beam is sleeved on the cross beam when the bottom plate is not lifted, so that the lower surface of the bottom plate is attached to the underframe, and the gravity center of goods of a carriage is greatly reduced.

Furthermore, a diversion angle is arranged on a side (unloading side) boundary beam which is rotationally connected with the inner tipping bucket (bottom plate). The draft angle is preferably disposed beyond the plane of the bottom frame so that the bottom plate rotates about the side rails to a desired angle and then is flush with the draft angle to provide a discharge surface of the same inclination. .

Preferably, after the internal overturning bucket is lifted, the internal overturning bucket can reach a state that an included angle of 40-50 degrees is formed between the bottom plate and the underframe, so that the goods can flow down from all sides in a self-unloading mode.

The carriage also comprises a front baffle, a rear baffle, a side baffle and a side baffle small door; the front baffle, the rear baffle, the middle baffle (optional) and the upper side beams of the side baffles are connected with the underframe and the side beams into a whole to form a complete large frame structure. Preferably, the left side and the right side (long sides) of the carriage body are respectively provided with a side baffle (and an upper side beam thereof), the side baffle at the unloading side is rotationally connected with a side baffle small door, and the lower end of the side baffle small door can be locked with the side beam; the side baffle plate on the lifting side is matched with the side baffle plate of the inner tipping bucket, and the side baffle plate form an integral side baffle plate of the carriage body when the side baffle plate is not lifted. Preferably, said side barrier small door on the discharge side is provided with an (remotely controlled) automatic unlocking mechanism and an automatic lifting mechanism. Preferably, the cooperation between the side baffle plate at the lifting side and the side baffle plate of the inner tipping bucket is arranged as a chamfer so as to facilitate the lifting of the side baffle plate. The tailgate is also a connection that can be locked/unlocked to the bottom frame (chassis).

The invention provides a self-unloading carriage with a frame turned on one side, which radically solves the defects of the traditional side turning unloading mode from the following aspects, and provides a brand-new design conception mode with application and development prospects for single-side unloading requirements:

The single-side unloading process of the carriage product comprises the following steps: after the small side baffle door on the unloading side is opened (electrically), the granular goods originally abutted against the side wall on the side can automatically flow down due to the action of gravity, and the residual goods borne by the bottom plate can continuously flow down along with the rotation of the bottom plate until the angle of repose of the goods is exceeded, so that all the granules are left along the bottom plate to finish self-unloading.

(1) First, and most importantly, the position (in the transverse and longitudinal directions) of the center of gravity of the whole carriage body is slightly changed in the lifting and unloading process of the inner tipping bucket. In the whole self-unloading process, the whole frame structure of the carriage is always kept motionless: the carriage part at the unloading side has no displacement/deflection at all, especially the frame at the unloading side (bottom edge beam, top beam of side baffle, and upright part of frame and middle baffle), and the frame part at the opposite side (lifting side) has no deflection; and because the goods are self-flowing type particles, the particles continuously flow out of the carriage body in the lifting process, so that the gravity center of the horizontal direction of the particle pile still in the carriage body/bottom plate bearing is still and always positioned in the carriage body frame. Thus, the center of gravity shift of the whole cargo+box body in the horizontal direction (width direction) is greatly reduced compared with the center of gravity shift of the traditional whole side-turning box body. Moreover, based on continuous gravity flow of the goods and the design of the lifting inner tipping bucket, the gravity center lifting range of the goods and the carriage body is limited in the height direction because the position of the integral frame is unchanged, and is far smaller than that of the traditional side tipping carriage body. The gravity center change of the carriage product provided by the invention is greatly reduced in the self-unloading process, so that the stability and the unloading safety of the carriage body are greatly improved, the carriage product can be more suitable for various complex unloading sites, and the carriage product has great significance for practical application.

(2) On the basis, the design of the carriage of the invention does not change the appearance and standard requirements of the existing carriage products, can integrate the design into the existing carriage, has no convex objects outside, can completely pass the authentication of the + related departments, can be directly put into large-scale industrial application, has no whistle design of an air pavilion, and solves the practical/existing problems of single-side unloading by using the carriage plate composition and structure of the carriage itself, thereby realizing high efficiency with simplicity.

Besides, the carriage products and the skeleton trailer are fixed by fasteners at four corners required to be installed by regulations and standards, and the carriage can be pulled and transported without any connection, namely, the butted skeleton vehicle is not required to be refitted, so that the standardized and automatic manufacturing can be directly realized without any improvement requirement on the existing production line and matched equipment.

(3) The car of the present invention, for the longer car example, is more preferably of the segmented (two or more bins) design: the sectional type internal turning bucket design and the multi-lifting point support can effectively reduce the deformation probability of the bottom plate of the bucket, the energy supply/output requirement of a lifting mechanism (such as a hydraulic system) is small, and the service life of the whole product is prolonged; the side-turning risk of the vehicle can be further reduced by carrying out lifting in sections; meanwhile, the deformation rate of the bottom plate of the inner turning hopper is reduced, so that the materials of the carriage body can be more light (such as aluminum alloy, nonmetal and the like are selected), the cost is reduced, the total weight of the carriage body is lightened, and the carrying capacity of products is increased.

In addition, the sectional design is more friendly to operators in practical application. In the actual unloading process, when the carriage products mounted on the framework vehicle are unloaded, the heavy granular cargoes naturally scatter around the wheels below the vehicle framework after flowing down to a pile, even if the empty vehicle after unloading is driven off site due to overlarge body quantity by using a deflector and the like, additional tractor pulling or loader pushing or jacking translation equipment is generally needed to help the empty vehicle to leave the site, and the unloading efficiency is greatly reduced. In addition, the sectional design provided by the invention is preferable to firstly discharge goods in a warehouse far away from the position (tail part) of the power vehicle, and after the goods in the warehouse are discharged, the weight of the goods in the front warehouse is just pressed on the driving wheel of the tractor, so that the vehicle is easy to be started and push-pull is not needed. Finally, when the front side bin is unloaded, as the cargoes are few and the resistance is relatively small, the vehicle can be easily driven out, and the whole process can be quickly separated without the help of external force.

(4) The self-unloading product mainly needs to solve the problem of cargo leakage, and the carriage product structurally adopts the self-forming components (such as a bottom plate and a side baffle plate) of the traditional carriage, so that the main problems of supporting and leakage of the varus hopper are solved by forming a stable triangular lifting section and attaching to the fixed part for movement only through simple element addition and proper position selection of the diagonal bracing beam/triangle plate. Meanwhile, because the granular goods are used as the main service objects of the self-unloading products, the problems that partial granules (such as wet blocks and frozen blocks) are adhered to fixed parts (such as front and rear baffles and the like) can also exist due to the influence of various factors such as climate, temperature and humidity, and at the moment, the thin edges of each joint motion on the inner tipping bucket play a role of a scraping plate, so that the complete self-unloading is completed.

In the carriage structure provided by the invention, the inner tipping bucket changes the interior of the semitrailer carriage into the inner tipping bucket, and the inner tipping bucket falls down to be used as a cargo carriage for carrying cargos during loading; when unloading, after the small side baffle door is opened, the goods can flow a large part automatically, and then the inner tipping bucket is lifted from the interior of the carriage to one side through the lifting cylinder under the drive of hydraulic pressure, air pressure or other modes, so that the carriage body frame is not moved. The inner tipping bucket is lifted to one side to form a 40-50-degree state, and a slope larger than the angle of repose of the goods is formed, so that the goods can flow downwards to one side to be self-unloading, and the whole semi-trailer can be safely unloaded to one side of the vehicle under the condition of no movement. The carriage structure provided by the invention can be suitable for various semitrailers and dumpers with chassis. In order to increase the strength of the vehicle, and facilitate and rationalize unloading, the carriage of the invention can be divided into a plurality of independent internal overturning bucket units (one-section type, two-section type, three-section type, four-section type and the like) along the length direction. In addition, common goods can be loaded and unloaded from the small door of the rear baffle plate and also can be loaded and unloaded from the top; the automatic or manual tarpaulin system can also be installed at the top, can effectually be rain-proof or prevent the goods unrestrained, reaches the effect of environmental protection. The invention provides a self-unloading carriage structure with a side-turning frame, which has the advantages of simple structure, less gravity center deviation during unloading of a vehicle, high safety and convenient processing, can reduce the gravity center of the vehicle and strengthen the overall strength of the carriage, and can also play a role in diversion and sealing during unloading of the vehicle.

Detailed Description

The invention relates to a self-unloading carriage with a side-turning frame, which is further described below with reference to the accompanying drawings.

The term "frame rollover" as used herein means that the discharge bucket is located substantially always inside the whole frame of the product in the vehicle during the discharge process, and particularly means a design structure located always inside the frame in the horizontal direction of the whole frame.

Meanwhile, the bottom frame refers to a bottom support structure of the rib frame-shaped carriage or carriage body, which is commonly known in the art as a king or a groined (or a three-shaped) extending shape, and can be combined with a bottom plate matched with the bottom support structure to form the carriage body or the bottom surface of the carriage body. The edge beam is a design structure of the edge beam of the bottom supporting structure, is arranged to be attached to the long side of the bottom plate, is connected with the cross beams of the underframe which are mainly arranged in width, and forms a more stable bottom surface structure for being matched with various overturning arrangements of the bottom plate.

Here, a frame-tipped dump truck of the present invention is described taking the truck product of a two-stage semitrailer (a middle bulkhead 10 divided into two separate movable floor units) as an example. And, the arrangement modes of the lifting cylinders 8, 8' are divided into side-mounted mode and middle-mounted mode, and two embodiments are respectively described. In practice, however, the arrangement of the lifting cylinders in the cabin according to the invention is not limited to the two ways described in the embodiments (for example, a centrally arranged one may also be arranged in the inner dump box and provided with a corresponding middle receiving chamber), but other arrangements of the lifting cylinders may be used as defined within the spirit and scope of the invention.

Example 1

1-3, The self-discharging carriage with the frame turned on one's side is composed of a front baffle 1, a side baffle 2, a side baffle small door 3, a rear baffle 4, a bottom frame 5, side beams 6 (two), an inward turning bucket 7 (two), side lifting cylinders 8 (4), turning pins 9 and a middle partition board 10 (one).

The solution consists of a complete load-bearing bottom frame structure by making the frame of the semitrailer in the form of a side rail 6 with a fixation (discharge side/left side rail 6 with a guide angle protruding/extending beyond the bottom frame) and a bottom frame 5 (frame). An inner tipping bucket 7 and a lifting cylinder 8 arranged close to the lifting side are arranged on the underframe 5. Referring to fig. 2-3, the varus bucket 7 can be rotatably lifted along the left side beam 6 to effect self-unloading of the cargo carried in the dump bucket 7. Preferably, the left side beam 6 is provided with a draft angle (see left-hand enlargement in fig. 2 and 3).

Further, the front baffle 1, the rear baffle 4, the middle baffle 10 and the upper side beams of the side baffles 2 of the carriage body are all connected with the underframe 5 and the side beams 6 into a whole to form a complete/integral carriage body large frame structure, so that the functions of bearing the bottom of the carriage and supporting the carriage body strength are achieved. In the lifting and self-discharging process, the integral frame of the carriage body does not move, for example, the side baffle plate 2 and the side baffle plate small door 3 at the unloading side/left side are completely motionless in the lifting process, and only granular cargoes are dumped and moved leftwards, so that the force for driving the carriage body to integrally incline towards the left side and even roll over during unloading due to factors such as ground reasons, support and the like is not generated. The left side baffle plate 2 and the right side baffle plate 2 of the carriage body (and the edge beam at the upper part of the carriage body) are respectively provided with a side baffle plate small door 3 which is rotatably connected, and the lower end of the side baffle plate small door 3 can be locked/unlocked with the edge beam 6. The right side baffle plate 2 is matched with the inner turning bucket side baffle 7-2, and the right side baffle plate and the inner turning bucket side baffle plate form an integral right side baffle plate of the carriage body when not lifted. The tailgate 4 is also connected to the bottom frame (chassis 5) in a locking/unlocking manner.

Referring to fig. 2-3, the inner dump box 7 is composed of an inner dump box bottom plate 7-1, an inner dump box side block 7-2, and an inner dump box diagonal draw beam 7-3. Wherein, the inner tipping bucket bottom plate 7-1 falls on the bottom frame when not lifted, is used as a bottom plate of the carriage for carrying goods, the inner tipping bucket side baffle 7-2 is used as at least one part of a right side baffle of the carriage when not lifted, and both can adopt the process and the material (or the lighter material) of the mosaic plate used by the prior carriage and can play the roles of the corresponding bottom plate and the wall plate when carrying goods.

Preferably, the bottom beam of the inner tipping bucket bottom plate 7-1 (bottom surface) is directly sleeved on the cross beam of the underframe 5 by adopting a lower U-shaped (reverse U-shaped) structure, so that the cargo bearing surface (bottom surface of the bottom plate) of the inner tipping bucket 7 is attached to the cross beam of the underframe 5, a carriage structure of double-layer bottom surface is formed, and the cargo gravity center of a carriage is greatly reduced. The left side edge of the inner tipping bucket bottom plate 7-1 is rotationally connected with the convex diversion angle of the left side edge beam 6 through a turnover pin shaft 9 so as to rotate along the side edge beam 6; the right side of the inner dump bed 7-1 is connected (which may be welded as one piece, or may be detachably connected/sealed as in the side guard gate 3) to the inner dump bed side guard 7-2, which is lifted during lifting.

The inner tipping bucket side baffle 7-2 is matched with the right side baffle 2, and forms an integral side baffle of the carriage body when not lifted. The cooperation between the side baffle 2 and the side baffle 7-2 of the internal tipping bucket is preferably a chamfer (the inner side tangent point of the box body is higher than the outer side tangent point) so as to facilitate the lifting of the side baffle 7-2 of the internal tipping bucket.

The varus hopper diagonal draw beam 7-3 connects the internal dump bed 7-1 and the varus hopper side dams 7-2 (preferably the distal/distal ends of the two) for support of the two. The number of the internal tipping bucket oblique pull beams 7-3 is preferably two, and the sections of the front end and the rear end of the internal tipping bucket 7 are respectively provided with a plurality of internal tipping bucket oblique pull beams; there may be a plurality of: one or more pieces are arranged on the same section or one or more pieces are respectively arranged on different sections of the inner tipping bucket. In the embodiment, only the inclined pull beam 7-3 of the inner hopper is taken as an example to describe the supporting and scraping effects of the inclined pull beam; indeed, a triangle may be used in this example as well (e.g., a triangle is provided between the varus chute beam 7-3 and the right angle formed by the right side floor and the side rails in the illustration, thereby forming a "triangular bucket").

Each internal dump bucket 7 is preferably provided with two lifting cylinders 8, connecting the internal dump bucket 7 and the underframe 5, respectively. Two lifting cylinders 8 are arranged at the front and rear ends of the inner dump box 7, respectively. As shown in fig. 2 and 3 (also partly shown in perspective in fig. 1), in order to accommodate the lifting cylinders 8, to isolate them from the load and to provide openings for the lifting cylinders to connect to the underframe 5, two chambers (closed towards the inside of the load/car and open towards the underframe 5) are preferably provided on the right side of the front and rear ends of the skip bucket 7, accommodating the lifting cylinders 8. In fig. 2 and 3, the support of the lifting cylinder is shown in the chamber, the top of the piston rod of the lifting cylinder 8 is connected to the bottom frame 5, and in practice, the lifting cylinder 8 may be arranged in opposite directions (fixed to the bottom frame 5 by the support, the top of the piston rod being connected to a top seat arranged in the chamber).

As shown in fig. 3, after the inner tipping bucket 7 is lifted, the inner tipping bucket bottom plate 7-1 and the underframe 5 can be in a state of an included angle of 40-50 degrees, so that the goods can flow down from all sides in a self-unloading way.

The inner tipping bucket 7 lifts and self-unloading process along 40-50 degrees of the left side beam 6, so that the inner tipping bucket 7 and the goods therein are still integrally positioned in the carriage frame when reaching the highest point, the left offset of the integral gravity center of the carriage is small, and as the bottom plate is a rigid plate, the goods on the upper surface of the goods stack continuously drop along with the lifting process, and the upward movement amount of the integral gravity center of the carriage is also very small.

According to the scheme, a frame of a semi-trailer is made into a side beam 6 (a long side of a bottom surface) and a bottom frame 5 (the frame), an inner tipping bucket 7 is arranged on a carriage body at the upper part of the bottom frame 5 (a plurality of inner tipping bucket combinations are selected according to different lengths of vehicles), so that the interior of the semi-trailer is changed into the inner tipping bucket, and the inner tipping bucket 7 falls down when the semi-trailer is loaded; after the side baffle small door 3 is opened during unloading, the goods can flow a large part automatically, and then the inner tipping bucket 7 is lifted from the interior of the carriage under the action of the lifting cylinder 8 by the inner tipping bucket 7, so that the whole carriage body frame is not moved. The inner tipping bucket 7 is lifted to one side to form a 40-50 DEG slope which is larger than the angle of repose of the goods, so that the goods can flow downwards to one side to be self-unloading, and the whole carriage can be unloaded under the condition of no movement, thereby being very safe. The carriage of the invention can be suitable for various semitrailers and dump trucks with chassis. In order to increase the strength of the vehicle, the unloading is convenient and reasonable, the inside length direction of the carriage can be divided into a plurality of independent internal overturning bucket units (one-section type, two-section type, three-section type, four-section type and the like).
