Description

Carrier and turning device

Technical Field

The application relates to the technical field of solar module equipment, in particular to a carrier and a turnover device.

Background

With the development of photovoltaic module technology, the module size is getting larger. At present, the length and width of the mainstream 210 battery component can reach 2384mm multiplied by 1303 mm. When the large-size components are packaged, the packaging is limited by factors such as containers, plate trucks, road height limitation and the like, and a vertical packaging mode is generally adopted in the industry. The whole support photovoltaic module packaged in a vertical package mode has the height of 2400mm and the weight of about 1200 kg. Although vertical packing has improved conveying efficiency, whole support photovoltaic module's focus is too high, and vertical stacking is emptyd easily. Therefore, on the project site, the vertically stacked whole-support photovoltaic modules need to be adjusted to be horizontally stacked before the modules are unpacked and installed.

Therefore, in order to improve the installation efficiency of the whole-support photovoltaic module with large-size vertical packaging and reduce the safety risk, the vertically stacked modules need to be turned over by 90 degrees into be stacked transversely.

However, due to the large volume and weight of the entire-tray photovoltaic module, manual operation has a large risk and low efficiency.

SUMMERY OF THE UTILITY MODEL

Based on the above defects, the present application provides a carrier and a turnover device to partially or completely improve and even solve the problem that the whole-support photovoltaic module in the related art is difficult to turn over.

The technical problem of the present application is achieved by the following technical solutions:

in a first aspect, examples of the present application provide a vehicle comprising: the first object carrying surface and the second object carrying surface are connected through the connecting piece;

the fixing piece comprises two first hooks which are arranged on the first object stage at intervals and are far away from the connecting piece, and two second hooks which are arranged on the second object stage at intervals and are far away from the connecting piece;

first hoist and mount area and second hoist and mount area, first hoist and mount area links to each other with two first couples, and second hoist and mount area links to each other with two second couples.

In above-mentioned implementation process, the carrier is including being first objective table and the second objective table that moves about freely and quickly the setting (first objective table and second objective table are L shape setting promptly), and two objective tables link to each other through the connecting piece for place in the thing of placing (like whole support photovoltaic module) of first objective table, can place in the second objective table that moves about freely and quickly the setting with first objective table after the carrier upset.

And moreover, two first hooks and two second hooks are arranged at positions, far away from the connecting piece, of the first object stage and the second object stage respectively at intervals, and a hoisting belt is arranged to be connected with the two first hooks and the two second hooks respectively. When the object is turned (vertically and horizontally), the first stage is placed on the ground (or other operation table), the object to be turned is placed on the first stage, and a machine (such as a crane) for providing turning power lifts the carrier via the first hoisting belt and the second hoisting belt. Because the hoist and mount area sets up in the one end that connecting piece was kept away from to first objective table and second objective table, at the lifting in-process, the upset can take place for the target object slope leans on in the second objective table, then along with the slow decline of hoist, makes the second objective table of placing the target object contact with ground (or other operation panel), and then accomplishes the upset (the upset of vertical and horizontal direction) of target object.

Similarly, when the object is turned (turned in the vertical and horizontal directions) by the carrier, the second object stage can be placed on the ground (or other operation table), so that the object to be turned is placed on the second object stage, and in the process that a machine (such as a crane and the like) providing turning power lifts the carrier through the first sling belt and the second sling belt, the carrier can be turned, so that the object is inclined and leaned on the first object stage, and then the first object stage on which the object is placed is contacted with the ground (or other operation table) along with the slow descending of the crane, so that the turning (turning in the vertical and horizontal directions) of the object is completed.

With reference to the first aspect, in a first possible implementation manner of the first aspect of the present application, the connecting member has a first surface and a second surface that are opposite to each other, the first object carrying surface and the second object carrying surface are connected through the first surface, and the second surface is configured as a convex arc surface.

In the implementation process, one surface of the connecting piece, which is opposite to the object carrying surface, is set to be a convex arc surface, so that the part of the carrier, which is in contact with the ground (or other operation tables), is in a curve shape of the convex arc surface in the process of slowly lifting or descending the carrier. The curved contact surface is arranged, so that the phenomenon that the connecting piece is broken or the ground (or other operation platforms) is scratched or dented in the lifting or descending process of the carrier can be avoided, and the cost of the overturning operation of the target object is reduced (the reduction of the operation cost is realized by reducing the loss rate of the carrier and the operation platforms).

With reference to the first aspect, in a second possible implementation manner of the first aspect of the present application, the connecting member has a first surface and a second surface opposite to each other, and the first object carrying surface and the second object carrying surface are connected through the first surface;

and the wheels are arranged on the connecting pieces, and rotating shafts of the wheels are connected with the second surface.

In the implementation process, the wheels are arranged on the surface, deviating from the object carrying surface, of the connecting piece, and the wheels can enable the carrier to be in sliding contact with the ground in the slow lifting or descending process of the carrier, so that the concentrated acting force between the connecting piece and the ground is further reduced. The wheels are arranged to enable the carrier to be in sliding contact with the ground, and the acting force that the crane lifts the carrier to enable the target object to be overturned to be placed on another object stage to be overturned can be reduced.

With reference to the first aspect, in a third possible implementation manner of the first aspect of the present application, the wheel includes two rollers disposed at an interval.

In the implementation process, the two rollers are arranged on the side, deviating from the carrying surface, of the connecting piece at intervals, so that the acting force of the carrier on the wheels is transmitted to the two rollers more uniformly in the slow lifting or descending process of the carrier, and the probability that the wheels are damaged (for example, a single roller bears excessive pressure, and is easy to deform or break and the like) in the lifting or descending process of the carrier is further reduced.

With reference to the first aspect, in a fourth possible implementation manner of the first aspect of the present application, the carrier is further provided with a support;

the support comprises two support legs which are arranged on the first bottom surface at intervals;

or the support comprises two support legs arranged on the second bottom surface at intervals;

or the support comprises two first support legs arranged on the first bottom surface at intervals and two second support legs arranged on the second bottom surface at intervals.

In the implementation process, the support is arranged on the bottom surface of one or both of the first objective table and the second objective table, so that the carrier can be more stable in the use process (because the wheel is arranged on the side of the connecting piece deviating from the object carrying surface, and if the wheel slides, the wheel needs to protrude out of the bottom surface of the objective table by a certain height.

With reference to the first aspect, in a fifth possible implementation manner of the first aspect of the present application, the first object stage and the second object stage are steel frames, and the connecting member is a welding member connecting the two steel frames.

In the implementation process, the first objective table and the second objective table are arranged to be steel frames, the steel frames have high strength and can support the target object with large weight, so that the situation that the target object falls due to insufficient strength of the objective tables in the process of overturning the target object by means of a carrier is avoided, the target object is damaged, and the cost of overturning operation of the target object is increased.

In addition, compared with a flat steel plate, the steel frame has a hollow area with a certain area, so that the self weight of the carrier can be reduced, and the energy consumption of a device (such as a crane) for providing overturning power is reduced.

In addition, set up the connecting piece into the welding piece of two steelframes that set up with great ease of welding, the fastness between welding piece and steelframe is higher to further improve the stability of carrier.

With reference to the first aspect, in a sixth possible implementation manner of the first aspect of the present application, the first hook and/or the second hook is a galvanized steel bar hook.

In the implementation process, one or both of the first hook and the second hook are set to be galvanized steel bar hooks, so that the hooks have higher strength and stability, and the falling of the target object caused by the breakage of the hooks in the use process of the carrier is avoided. And the galvanized steel bar hook can be connected with the objective table of the steel frame in a welding mode, so that the galvanized steel bar hook is more tightly connected with the objective table.

In the implementation process, the target object is placed on the first object stage or the second object stage, and the self weight of the target object is larger, so that larger pressure is generated on the corresponding first object stage or the second object stage, and especially larger tension is generated on the connecting piece. In the lifting or descending process of the carrier with the target object, the reinforcing ribs with two ends respectively connected with the first object carrying surface and the second object carrying surface are arranged, so that the pressure of the target object on one object carrying platform can be transmitted to the other object carrying platform, and the stability of the carrier is improved. And, set up the strengthening rib that both ends link to each other with first year thing face and second year thing face respectively, can also strengthen the connecting action of connecting piece to first objective table and second objective table (avoid the connecting piece to bear too big extrusion force and can't effectively connect first objective table and second objective table).

The reinforcing ribs are provided with the two steel pipes which are arranged at intervals, so that acting force borne by the reinforcing ribs is more uniform (the pressure generated by a target object on one of the object stages can be more uniformly transmitted to the other object stage). And the steel pipe has higher strong hardness and lower manufacturing cost, can be better the stability of maintaining the carrier and promote the economic suitability of carrier.

In a second aspect, examples of the present application provide a flipping apparatus comprising:

Detailed Description

Embodiments of the present application will be described in detail below with reference to examples, but those skilled in the art will appreciate that the following examples are only illustrative of the present application and should not be construed as limiting the scope of the present application. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.

The carrier and the turning device provided by the embodiments of the present application are specifically described as follows:

with the development of photovoltaic module technology, the module size is getting larger. At present, the length and width of the mainstream 210 battery component can reach 2384mm multiplied by 1303 mm. When the large-size components are packaged, the packaging is limited by factors such as containers, plate trucks, road height limitation and the like, and a vertical packaging mode is generally adopted in the industry. The whole support photovoltaic module packaged in a vertical package mode has the height of 2400mm and the weight of about 1200 kg. Although vertical packing has improved conveying efficiency, whole support photovoltaic module's focus is too high, and vertical stacking is emptyd easily. Therefore, on the project site, the vertically stacked whole-support photovoltaic modules need to be adjusted to be horizontally stacked before the modules are unpacked and installed.

Therefore, in the installation of photovoltaic module, in order to improve photovoltaic module's installation effectiveness, reduce the safety risk, need become transversely stacking with the 90 degrees upsets of the subassembly of vertical stacking.

However, because the whole photovoltaic module has a large volume and a heavy weight and does not have a corresponding turning tool, the current 90-degree turning stacking modes of the large-size vertical-packaged photovoltaic module mainly include the following two modes:

firstly, support every support battery pack with the support of unpacking earlier and prevent that the subassembly from empting, demolish the packing afterwards, adopt the mode of artifical transport to stack photovoltaic module by 90 degrees upsets one by one.

The second is, do not adopt auxiliary stand, directly tie whole support subassembly with the rope, hoist photovoltaic module with the crane, workman promotes whole support subassembly upper end, makes the subassembly 90 degrees upsets stack.

However, in the first mode, the physical strength of workers is high, the photovoltaic module is heavy, and the hands are easy to be damaged, so that safety accidents are caused. In the second mode, because there is not the auxiliary stand support, at the in-process that the workman promoted, the subassembly upset direction is difficult to control, easily leads to photovoltaic module to damage and personnel are injured. Both the two modes have great potential safety hazards and low overturning efficiency.

Therefore, the inventor provides a carrier and turning device, and the carrier is including being the first objective table and the second objective table that move about freely and quickly the setting, and two objective tables pass through the connecting piece and link to each other for place in the whole photovoltaic module of one of them objective table, can make the carrier be and move about freely and quickly the upset back of direction place in another objective table under the effect of jib loading boom, and then accomplish vertical whole supporting photovoltaic module's of placing horizontal stacking.

The carrier and the turnover device provided by the present application are further described in detail with reference to the following embodiments.

Example 1

Fig. 1 shows a carrier 100, and fig. 1 is a schematic structural diagram of the carrier 100 according to embodiment 1. The carrier 100 includes a first stage 10, a second stage 20, a connector 30, a first hook 41, a second hook 42, a first sling 51, and a second sling 52.

Wherein, first objective table 10 and second objective table 20 pass through connecting piece 30 and vertically and horizontally link to each other (first objective table 10 and second objective table 20 are the setting of L shape promptly) for whole support photovoltaic module homoenergetic before and after the upset can be placed in corresponding objective table. The first object stage 10 is provided with a first hook 41 far away from the connecting member 30, and the second object stage 20 is provided with a second hook 42 far away from the connecting member 30, and is provided with a first hoisting belt 51 connected with the first hook 41, and a second hoisting belt 52 connected with the second hook 42. The device for providing the overturning power lifts and drops the carrier 100 through the first lifting belt 51 and the second lifting belt 52, so that the carrier 100 is stably placed on a corresponding workbench after being overturned in the longitudinal and transverse directions.

The first stage 10, the second stage 20, the connecting member 30, the first hook 41, the second hook 42, the first sling 51, and the second sling 52 of the present example will be described in detail below with reference to the drawings.

The first stage 10 and the second stage 20 are used to place an object to be flipped, such as a full-stand photovoltaic module. In the example, the first stage 10 and the second stage 20 are plate-shaped steel frame structures, the first stage 10 and the second stage 20 are vertically connected, and the first stage 10 and the second stage 20 are connected by welding (i.e., the connecting member 30 is a welding member).

To accommodate the flipping of the fully-cradled photovoltaic module (the vertical length of the fully-cradled photovoltaic module before flipping is greater than its lateral length), in an example, the vertical length of the vertically-disposed first stage 10 is greater than the lateral length of the laterally-disposed second stage 20 before the vehicle 100 flips.

The specific arrangement form of the first object stage 10 and the second object stage 20 is not limited in the present application, and relevant personnel can perform corresponding adjustment under the condition that the object to be turned can be placed on the corresponding object stages before and after turning.

In some possible embodiments, the first stage 10 and the second stage 20 may be configured with suitable strength and size according to the weight and size of the object to be flipped, so as to avoid instability of the stages due to the object bearing too heavy weight. For example, when the object with a large weight is to be turned over, the first stage 10 and the second stage 20 may be configured to have a steel plate structure. When the object with a small weight is turned over (for example, some objects with a long vertical dimension which are difficult to turn over by a human being), the first object stage 10 and the second object stage 20 may be configured to have a wood board or wood frame structure.

Alternatively, the first stage 10 and the second stage 20 may not be vertically disposed, and an included angle between the object carrying surface of the first stage 10 and the object carrying surface of the second stage 20 (i.e., an included angle between the first object carrying surface and the second object carrying surface) may be adjusted within a certain range of about 90 degrees, including but not limited to 80 degrees, 85 degrees, 89 degrees, 95 degrees, or 120 degrees. However, when the included angle between the first object carrying surface and the second object carrying surface is set to be slightly larger than 90 degrees, the whole-support photovoltaic module of the vertical package is in contact with one object carrying surface before overturning, the height direction of the whole-support photovoltaic module is not in contact with the other object carrying surface (or the contact area is smaller), and the whole-support photovoltaic module is easy to topple due to the fact that the gravity center of the whole-support photovoltaic module is too high, and the instability of overturning operation is increased. When the included angle between the first object carrying surface and the second object carrying surface is set to be slightly smaller than 90 degrees, the contact area between the object to be overturned and the other supporting surface is small in the overturning process, and the object may be damaged due to stress concentration.

In order to connect the first stage 10 and the second stage 20, which are vertically and horizontally arranged, a connecting member 30 is further provided.

In the illustrated example, the connector 30 is provided as a weldment to provide a more secure connection between the two stages of the steel frame structure.

The concrete setting form of connecting piece 30 is not restricted in this application, and relevant personnel can carry out corresponding adjustment under the circumstances of guaranteeing that connecting piece 30 can make two objective tables of setting with great ease firmly connect.

In some possible embodiments, the connecting member 30 may be an L-shaped steel plate, both ends of the L-shaped steel plate are provided with threaded holes, and both ends of the steel plate are respectively connected with the two object stages through the cooperation of screws and the threaded holes. Alternatively, the connecting member 30 may be integrated with the first stage 10 and the second stage 20. For example, the first stage 10 and the second stage 20 are formed by bending a steel plate by 90 degrees.

In order to facilitate the turning of the vehicle 100 by the turning power device, a first hook 41 connected to the first stage 10 and a second hook 42 connected to the second stage 20 are further provided.

In the example, the first hooks 41 are two galvanized steel bar hooks, and the two first hooks 41 are spaced apart from each other at the top end of the vertically arranged first stage 10 (the bottom end opposite to the top end is connected to the second stage 20 through the connecting member 30). The second hooks 42 are two galvanized steel bar hooks, and the two second hooks 42 are arranged at the right end of the transversely arranged second object stage 20 at intervals (the left end opposite to the right end is connected with the first object stage 10 through the connecting piece 30).

The application does not limit the specific arrangement form of the first hook 41 and the second hook 42, and related personnel can perform corresponding adjustment under the condition that the lifting belt connected with the first hook 41 and the second hook 42 keeps stable in the process of lifting or descending the carrier 100. In some possible embodiments, the first hook 41 or the second hook 42 may be respectively provided as 3 hooks, and three hooks are spaced apart from each other at the top end of the vertically arranged first stage 10 or at the right end of the horizontally arranged second stage 20. Alternatively, one or both of the first and second hooks 41 and 42 may be provided as a circular ring. The ring may be formed by a through hole provided at an end of the object table remote from the attachment 30.

To facilitate the turning of the vehicle 100 by the turning power-providing apparatus, a first sling 51 connected to the first hook 41 and a second sling 52 connected to the second hook 42 are further provided.

In the example, the two ends of the first sling 51 are connected to the two first hooks 41, respectively, and the two ends of the second sling 52 are connected to the two second hooks 42, respectively, so that the first sling 51 and the second sling 52 can be suspended from the device for providing the turning power.

The specific arrangement form of the first hoisting belt 51 and the second hoisting belt 52 is not limited by the application, and related personnel can perform corresponding adjustment under the condition that the device for providing overturning power can lift the carrier 100 through the hoisting belts and enable the carrier 100 to overturn (the overturning means that the carrier 100 overturns by 90 degrees, so that the object stages arranged vertically and horizontally are in contact with the ground in turn before and after overturning).

In some possible embodiments, the first sling 51 is provided in two separate pieces, each of the first hooks 41 being fixed to both ends of one of the first sling 51. When the carrier 100 is used to turn over an object, both first sling belts 51 are connected to a device for providing turning power. The second sling 52 may be provided in a different form from the first sling 51 (i.e., the second sling 52 may be provided in two separate pieces, and the first sling 51 may be provided in one piece).

In the example, the carrier 100 further includes two rollers 60 disposed at intervals at the connecting member 30, and a rotation axis of the roller 60 is connected to a surface of the connecting member 30 facing away from the object carrying surface. The roller 60 is arranged on the side of the connecting piece 30 departing from the object carrying surface, and in the slow lifting or descending process of the carrier 100, the carrier 100 can be in sliding contact with the ground through the roller 60, so that the concentrated acting force between the connecting piece 30 and the ground and the energy consumption of a device for providing overturning power are further reduced.

Whether the carrier 100 is provided with the roller 60 is not limited in the present application, and relevant personnel can perform corresponding adjustment according to needs. In some possible embodiments, in order to relieve the concentrated acting force of the connecting member 30 on the ground during the turning process of the vehicle 100 and reduce the energy consumption of the device for providing the turning power, the surface of the connecting member 30 facing away from the object carrying surface may be provided with a convex arc surface. For example, the right angle at the junction of the first stage 10 and the second stage 20, which are vertically connected, is set to a rounded structure (both the inner right angle connected to the object carrying surface and the outer right angle facing away from the object carrying surface may be set to a rounded structure, or only the outer right angle may be set to a rounded structure).

In order to make the carrier 100 more stable during use (since the roller 60 is disposed on the side of the connecting member 30 away from the object-carrying surface, and the roller 60 needs to protrude a certain height beyond the bottom surface of the object-carrying table if it is to slide), a support 70 is disposed on the bottom surface of the object-carrying table, and the height of the support 70 is consistent with the protruding height of the roller 60. In an example, two supports 70 are spaced apart from each other on the bottom surface of the first stage 10 (the roller 60 extends from the bottom surface of the first stage 10, and the roller 60 is flush with the bottom surface of the second stage 20, so that the supports 70 may not be provided on the bottom surface of the second stage 20).

The application is not limited to the specific arrangement form of the support 70, and the relevant personnel can make corresponding adjustment according to the needs. In some possible embodiments, a support 70 may be provided on the first stage 10, and the support 70 and the two rollers 60 are arranged in a triangular shape. Alternatively, when the roller 60 is extended to a certain height with respect to the second stage 20, a support 70 extended to the same height may be provided on the bottom surface of the second stage 20. Alternatively, the support 70 is not provided.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a turning device 200 according to embodiment 2 of the present application. The turning device 200 includes the carrier 100 provided in embodiment 1 and the crane arm 80, and the crane arm 80 is provided with a hook for hanging a hoisting belt.

The specific arrangement form of the cargo boom 80 is not limited in the application, and related personnel can adjust the cargo boom 80 correspondingly under the condition that the cargo boom 80 can turn over the carrier 100 through the lifting belt.

In some possible implementations, the lift arms 80 may be provided as telescoping arms connected perpendicularly to the cross-beam. Alternatively, the vehicle 100 may be raised and lowered by connecting a lift truck to a sling to effect the tilting of the vehicle 100.
