However, it still has some points to be perfected:

(1) the two tipping devices are all that the whole tipping device is arranged on the movable trolley, the steel (iron) water tank is moved by the movement of the movable trolley, the required installation space is large, and the transportation cost of newly produced equipment transported from a factory to a factory is large and the convenience is low. In addition, in the prior art, the motor is generally installed at the front wheel and the rear wheel of the mobile trolley to drive the trolley to move, but the steel (iron) water tank has a very large weight during operation, so that the motor power required by the single motor is relatively large and the cost is high, and one of the four wheels of the tipping device is driven by the large motor due to the operation of the single motor, so that the whole device is unstable during moving, in addition, the device can be normally placed on the ground only by three-point support, so that one of the four wheels of the device is in a suspended state under the action of inertia or centrifugal force during moving, if the suspended wheel is the wheel connected with the driving motor, the motor is in an idle state, the movement of the device is greatly influenced, and even the whole device can tip over in severe cases, major safety accidents occur; when the front wheel and the rear wheel are respectively provided with one motor, although the motors with smaller power can be used, if one of the wheels connected with the motors is in a suspended state, the motor idles, so that the problem that the other motor generates great working load is caused, and the movement of equipment also becomes unstable; if a motor is installed at each wheel, the cost is too high to be compensated;

(2) in the working process of moving the tipping device, a power line of a motor often has a certain dragging problem along with the movement of the tipping device, a longer power line is dragged and dropped on the ground or a rack, so that workers on site are easy to trip, the power line is easy to stir to a working area of the device or drag to a moving guide rail of the device, the device or the power line is damaged, the working efficiency of the device is influenced, and even safety accidents are caused;

(3) when the molten steel (iron) is poured by the molten steel (iron) pot, the molten steel (iron) is difficult to accurately guide into casting equipment, the molten steel (iron) is easy to sputter onto the surface of the equipment and the surrounding environment, the equipment is damaged, in addition, the pouring amount is difficult to control, the quality of a product formed during casting is influenced, if the molten steel (iron) is poured into a mould during casting operation in a silicon iron plant, if the molten steel is poured excessively, the molten iron overflows, the quality of cast iron forming is influenced, the size of cast iron formed when the pouring amount is small cannot meet the requirement, and secondary operation may be needed;

Detailed Description

The invention will be further described with reference to specific embodiments and drawings.

Example 1

As shown in fig. 1 to 4, a mobile tilting apparatus for a ladle is mainly used for steel or iron making to perform a pouring operation for pouring molten steel into a casting apparatus.

The tipping device comprises a base 1, a movable support 2 and a first power unit, wherein the base 1 is provided with a vertical column 101, the movable support 2 is hinged to the upper end of the vertical column 101, and the first power unit is used for driving the movable support 2 to turn over along the hinged part of the movable support 2 and the vertical column 101, so that a steel (molten iron) tank 6 on the movable support 2 finishes tipping action, and the steel (molten iron) in the steel (molten iron) tank is poured into a casting device to finish casting work. The first power unit of this embodiment adopts pneumatic cylinder 3, and pneumatic cylinder 3 has two, and the symmetry sets up in the both sides of movable support 2, and the one end of pneumatic cylinder 3 is articulated with articulated seat 104 on the base 1 and is connected, and the other end then is articulated with the upper end of movable support 2 and is connected, thereby two pneumatic cylinders 3 combined work accomplish the work of empting of steel (iron) water. It is worth mentioning that, in the initial state, the hydraulic cylinder 3 and the horizontal plane form an included angle of 90 degrees, the swing angle of the hydraulic cylinder 3 is small, and the required stroke is short, so that the bending moment applied to the hydraulic cylinder 3 in the working process is small, the abrasion of the hydraulic cylinder 3 in the working process is effectively reduced, and the service life of the hydraulic cylinder 3 is prolonged.

The main structure of the tipping device is as above, and the tipping work of the molten steel (iron) can be completed through the structure. However, the conventional tipping device is difficult to move, firstly, the tipping device is lifted by a high-altitude crane, the cost is high, accidents are easy to occur, secondly, the tipping device is placed on a movable trolley, the pouring work is completed before the tipping device is sent to a casting device through the movable trolley, and the inventor also tries to place the tipping device on the movable trolley to move the tipping device, however, a plurality of problems are generated in the practical process:

(1) the movable trolley and the tipping device are two devices essentially, and the conventional trolley is difficult to perfectly cooperate with the tipping device, so that the trolley needs to be customized or modified according to the volume and the structure of the tipping device, and the cost is high;

(2) in the actual operation process, when the tipping device works, the movable trolley is easy to collide with some casting devices, so in order to avoid collision between the trolley and the casting devices, the tipping device needs to finely adjust the position of the tipping device or to enable the position of the tipping device on the trolley to be closer to the casting devices, so that the steel (molten iron) can be accurately poured into the casting devices, generally speaking, the mode is difficult to adapt to various casting devices, and the structure of the trolley needs to be adjusted according to different casting devices, so that time and labor are wasted;

(3) the customized or modified trolley and the tipping equipment are transported to a factory from a manufacturer together, the transportation is troublesome, the convenience is low, and the occupied working space is large when the trolley is used;

(4) the most important point is that the tipping device of the moving mode is not stable enough in the moving process, firstly, the tipping device is difficult to be fixed on a trolley perfectly, the self weight of the tipping device is large, the tipping device is easy to slide relative to the trolley, in addition, in the prior art, motors are arranged at the front wheel and the rear wheel of the trolley to drive the trolley to move, but because the weight of a steel (iron) water tank is extremely large when in work, the motor power required when only a single motor is used for driving is large, the cost is high, and the operation of the single motor can lead one of the four wheels of the tipping device to be subjected to large motor driving force, so that the whole device is unstable when in moving, in addition, because the device can be normally placed on the ground only by three-point support, the whole device can be in a suspension state under the action of inertia or centrifugal force when in moving, if this unsettled wheel is the wheel of being connected with driving motor this moment, then can lead to the motor to be in idle running state, causes very big influence to the removal of equipment, can even make whole equipment to overturn when serious, produces great incident. When the front wheel and the rear wheel are respectively provided with one motor, although the motors with smaller power can be used, if one of the wheels connected with the motors is in a suspended state, the motor idles, so that the problem that the other motor generates great working load is caused, and the problem that the movement of equipment is unstable due to larger driving force applied to the single wheel is also caused; if a motor is installed at each wheel, the cost is too high, and the installation is complicated and not easy to be compensated.

Therefore, the inventor sets a new traveling mechanism on the tilting apparatus to solve the above problems. The traveling mechanism comprises a traveling wheel 102 which is arranged below the base 1 and used for moving the tipping device by driving the base 1 to move, and a second power unit which drives the traveling wheel 102 to work. The second power unit of the embodiment adopts a motor 103, and an output shaft of the motor is connected with the road wheel 102 through a coupling or a bearing or a key. Generally, the number of the walking wheels 102 is double, and the walking wheels are symmetrically arranged on two opposite sides of the base 1 so as to maintain the stability of the whole device in the moving process. In actual use, the four traveling wheels 102 are used in the optimal number, so that the movement stability of the equipment can be ensured, and the installation time and cost of the traveling wheels 102 are saved to the greatest extent. Because the walking wheel 102 has small volume and is not large as the occupied installation space of a trolley, the tipping device for installing the walking wheel 102 can adapt to most casting equipment, the problem of collision between the trolley and the casting equipment can not occur, and the use is convenient. In addition, the travelling wheels 102 and the base 1 can be installed together for transportation, the transportation is convenient, the travelling wheels can be perfectly matched with the tipping equipment for working, and the casting efficiency of the tipping equipment is effectively improved. Besides, in the practical operation of the embodiment, the track 8 matched with the walking wheels 102 is further arranged below the walking wheels 102, so that the motion of the walking wheels 102 is guided, and the device is prevented from moving and deviating so as not to accurately reach the front of the casting device.

It should be noted that, in order to solve the problem that the tipping device is unstable during moving, in the present embodiment, a pair of traveling wheels 102 with the same axis, which are symmetrically disposed on both sides of the base 1, are in transmission connection through a synchronizing shaft 106, and both ends of the synchronizing shaft 106 are respectively connected with one traveling wheel 102 through bearings. In this way, the pair of walking wheels 102 can work synchronously, so that on one hand, the walking wheels 102 on both sides of the tipping device drive the tipping device to move together, the device moves more stably, and on the other hand, even under the action of inertia force or the vibration of the equipment, one walking wheel 102 connected with the motor 103 is in a suspended state, due to the principle of three-point support, the other road wheel 102 connected with the road wheel 102 through the synchronous shaft 106 is necessarily in contact with the track 8, the motor 103 does not run idle, so that the uneven stress caused by the increase of the working load of another motor 103 or the overlarge driving force of a single road wheel 102 of the device compared with the rest road wheels 102 is avoided, and the phenomenon that the whole equipment is unstable in movement is driven, and the working safety and stability of the tipping equipment are effectively improved.

In addition, the embodiment also installs the chute 5 which receives and guides the molten steel (iron) to the casting equipment on the upright column 101, and the installation position of the chute 5 is at the pouring position of the molten steel (iron), thereby further enhancing the accuracy of pouring the molten steel (iron) to the casting equipment and improving the casting efficiency.

In conclusion, the movable type steel (hot metal) ladle tipping device can adapt to most casting devices, casting work can be accurately and efficiently carried out, adaptability is high, the method of connecting the synchronous shafts 106 is adopted, the problem of instability of the tipping device during moving is effectively solved, and the moving stability of the device is high.

Through this kind of mode, solved the above-mentioned hydraulic pressure station and be difficult to arrange and the problem that oil pipe is difficult to handle, reduced the installation space of tipping device, whole device integrates more, and it is more convenient to work.

In addition, in the arrangement of the chute 5. In this embodiment, a connecting beam 105 is connected between two columns 101, and the chute 5 is arranged on the connecting beam 105, and since the water tank 6 is placed in the middle of the two columns 101, the pouring opening of the molten steel (iron) is located in the middle of the connecting beam 105, and therefore the chute 5 is installed in the middle of the connecting beam 105, and can conveniently and accurately receive the molten steel (iron).

Example 3

The embodiment provides a dumping guide type hydraulic tipping device, which is based on embodiment 1 and embodiment 2, further improves the structure of a chute 5, improves the stability of the chute 5, and prevents splashing of molten steel (iron).

In this embodiment, the chute 5 has guaranteed the stability of chute 5 in equipment course of operation through chute bracket 501 and chute support 502, thereby can not take place to rock and influence the result of use of chute 5. Wherein, chute bracket 501 is installed in the lower extreme of chute 5, and chute 5 passes through chute bracket 501 to be installed on base 1, and chute support 502 side support sets up on tipping device's lower terminal surface, plays the supporting role to chute 5, strengthens chute 5's stability.
