[0024] When using the material transfer vehicle 100 of the embodiment of the present invention, the driving device 2 is controlled to start through the control component, and the driving device 2 drives the traveling wheels 11 to rotate, so as to realize the overall movement of the material transfer vehicle of the embodiment of the present invention. After the transfer vehicle 100 moves to the position of the material to be transported, the driving device 2 is turned off, and the telescopic support member 3 is started to make the telescopic support member 3 extend. The telescopic support member 3 abuts against the ground, so that the material transfer vehicle 100 of the embodiment of the present invention is fixed. Then, the driving member 41 is controlled through the control component to extend the lifting rope 42, so as to drive the lifting member 43 to descend. When the lifting member 43 descends to the set position, the driving member 41 is turned off, and the material is fixed to the lifting member 43. Then, the driving member 41 is started to roll up the lifting rope 42, so as to drive the lifting member 43 and the material to rise. When the material rises to a certain height or the set height, the driving member 41 is turned off. Then, the telescopic support member 3 is controlled to shorten through the controller, so that the lower end of the telescopic support member 3 is separated from the ground, and then the driving device 2 is started to drive the traveling wheels 11 to rotate, so as to realize the overall movement of the multifunctional transfer vehicle of the embodiment of the present invention. When the transfer vehicle moves to the set position, the material can be unloaded.

[0025] For the material transfer vehicle of the embodiment of the present invention, the vehicle frame 1 encloses a hoisting space, which penetrates in the second direction. This hoisting space provides space for the transfer vehicle to hoist materials; the vehicle frame 1 is provided with traveling wheels 11 and a driving device 2, which can realize the overall movement of the transfer vehicle without being restricted by tracks, with a large moving range and high flexibility, and can adapt to different working places and handling requirements; in the extended state of the telescopic support member 3, the vehicle body can be fixed to keep the overall stability of the transfer vehicle, which is beneficial to improving the safety of the transfer vehicle during the process of hoisting and unloading materials.

[0026] Therefore, the whole operation process of the material transfer vehicle 100 of the embodiment of the present invention for transferring materials is simple and fast, which improves the material transportation efficiency. It can be used for the loading, unloading and transfer of some conventional materials, and can also be used for the hoisting requirements during the assembly and maintenance of some equipment.

[0027] For the sake of easier understanding of the solution of the present application, it is described by taking the first direction being the same as the left-right direction, the second direction being the same as the front-back direction, and the third direction being the same as the up-down direction as an example. Among them, the left-right direction is as Figure 1 and Figure 2 shown, the front-back direction is as Figure 1 shown, and the up-down direction is as Figure 1 and Figure 2 shown.

[0028] The material transfer vehicle 100 of the embodiment of the present invention includes a vehicle frame 1, a driving device 2, a plurality of telescopic support members 3, a hoisting assembly 4, a control component, a storage plate 5, a limit collar 6 and a driving motor 7.

[0029] The vehicle frame 1 includes a left frame body, a right frame body, and an upper frame body. The vehicle frame 1 is integrally in an "n" shape, enclosing an "n"-shaped hoisting space, and the vehicle frame 1 is symmetrical left and right.

[0030] In this embodiment, the left frame body, the right frame body, and the upper frame body are all processed from square steel.

[0031] A plurality of traveling wheels 11 are provided on both the left and right sides of the vehicle frame 1, and electric steering wheels 12 are provided on both the left and right sides of the vehicle frame 1.

[0032] As Figure 1 shown, two traveling wheels 11 and one electric steering wheel 12 are provided on both the left and right sides of the vehicle frame 1. The electric steering wheel 12 is located at the front end of the vehicle frame 1. The electric steering wheel 12 can steer, and personnel can control the direction of the vehicle frame 1 and the transporter 100 by controlling the direction of the electric steering wheel 12.

[0033] The driving device 2 is provided on the vehicle frame 1, and the driving device 2 is in transmission connection with the traveling wheels 11. Specifically, there are two driving devices 2, the driving device 2 is a motor, the two motors are respectively located on the left and right sides, and the motor is in transmission connection with one traveling wheel 11 on the same side. The motor drives the traveling wheel 11 to rotate, thereby driving the entire vehicle frame 1 and the transporter 100 to move.

[0034] A plurality of telescopic support members 3 are respectively provided on both sides of the vehicle frame 1 in the first direction. The telescopic support members 3 and the traveling wheels 11 are both located at one end (lower end) of the vehicle frame 1 in the third direction. The telescopic support members 3 are electric telescopic support members 3.

[0035] The hoisting assembly 4 includes a driving member 41, a hoisting rope 42, and a hoisting member 43. The driving member 41 is provided on one side (right side) of the vehicle frame 1 in the first direction. The driving member 41 is connected to one end of the hoisting rope 42. The hoisting rope 42 is movably provided on the vehicle frame 1. The other end of the hoisting rope 42 passes through the other end (upper end) of the vehicle frame 1 in the third direction, and the other end of the hoisting rope 42 is connected to the hoisting member 43.

[0036] Specifically, the driving member 41 is a winch, and the hoisting rope 42 is a steel wire rope.

[0037] As Figure 2As shown, the limiting ring 6 includes an outer ring 61 and an inner ring 62. The outer ring 61 is arranged at the other end (upper end) of the frame 1 in the third direction, and the inner ring 62 is arranged on the hanging member 43. The hanging rope 42 is passed through the outer ring 61 and the inner ring 62. A plurality of limiting grooves are provided on the outer side of the inner ring 62 or the inner side of the outer ring 61 at equal intervals along the circumferential direction, and a plurality of limiting convex strips are provided on the inner side of the outer ring 61 or the outer side of the inner ring 62 at equal intervals along the circumferential direction, and the limiting convex strips cooperate with the limiting grooves. After the lifting component 43 of the lifting assembly 4 fixes the material, as the lifting rope 42 rises, the lifting component 43, the inner ring 62 and the material rise synchronously. When the inner ring 62 moves into the outer ring 61, the driving component 41 stops winding the lifting rope 42, and the lifting component 43, the inner ring 62 and the material stop rising. At this time, due to the cooperation of the limit groove and the limit strip between the inner ring 62 and the outer ring 61, the inner ring 62 and the outer ring 61 are fixed in the circumferential direction, that is, the lifting component 43 and the material are fixed relative to the frame 1 in the circumferential direction. Then, as the transfer vehicle 100 moves, the material will not rotate circumferentially, so that the fluctuation of the material in the transfer stage is small and the stability is good, which is conducive to further improving the safety and reliability of the multifunctional transfer vehicle of the embodiment of the present invention.

[0038] Among them, a plurality of limiting grooves and limiting strips 621 are arranged at equal intervals along the circumferential direction, and the alignment and matching of different limiting strips and limiting grooves facilitate the alignment of the inner ring and the outer ring when the inner ring rises.

[0039] Specifically, a plurality of limiting grooves are provided at equal intervals along the circumferential direction on the inner side of the outer ring 61 , and a plurality of limiting convex strips 621 are provided at equal intervals along the circumferential direction on the outer side of the inner ring 62 .

[0040] The frame 1 is provided with storage plates 5 on both sides in the first direction. The storage plates 5 can store materials, facilitating temporary storage of materials on the transfer vehicle.

[0041] Furthermore, the storage plate 5 is an electric telescopic plate. The electric telescopic plate is telescopic in the left-right direction. When the electric telescopic plate is extended in the left-right direction, the storage area of ​​the storage plate 5 can be increased, and the convenience of storage can be improved. When the size of the electric telescopic plate in the left-right direction affects the lifting of materials by the lifting assembly 4, the electric telescopic plate can be controlled to shorten.

[0042] In some embodiments, the outer ring 61 is rotatably arranged on the frame 1, and the lifting assembly 4 further includes a driving motor 7, which is arranged at the other end of the frame 1 in the third direction, and the driving motor 7 is connected to the outer ring 61. After the inner ring 62 moves into the outer ring 61, the driving motor 7 is turned on, and the driving motor 7 can drive the outer ring 61 to rotate, thereby driving the inner ring 62, the hanging member 43 and the material to rotate, so that the longer dimension of the material in the front-to-back direction can be rotated to the left-to-right direction, and then the driving member 41 is controlled to drive the lower side of the hanging member 43, and the two ends of the material are placed on the storage plate 5, and then the hanging member 43 is separated from the material.

[0043] The transfer method of placing the material on the storage plate 5 is suitable for the transfer of block-shaped, plate-shaped and irregular objects. The contact area between the material and the storage plate 5 is large, making the support of the frame 1 for the material more stable, thus facilitating the further improvement of the safety and reliability of the multi-functional transfer vehicle according to the embodiment of the present invention.

[0044] Specifically, the lifting component 4 further includes an external gear 611 and a driving gear 71. The external gear 611 is sleeved on the outer ring 61, and the driving gear 71 is arranged at the output end of the driving motor 7. The driving gear 71 meshes with the external gear 611.

[0045] It should be noted that the lifting rope 42 is spaced apart from the external gear 611, that is, when the lifting rope 42 passes through the inside of the external gear 611, the lifting rope 42 does not interfere with the external gear 611.

[0046] The lifting member 43 is any one of a hook, a lifting fixture or a manipulator. According to the characteristics of the material to be rotated, a suitable lifting member 43 is selected. For example, when it is necessary to transfer bagged materials or columnar materials after binding, the hook is selected as the lifting member 43, and the hook has a simple structure and low cost. When it is necessary to transfer columnar materials or block-shaped materials, the lifting fixture or the manipulator is selected as the lifting member 43.

[0047] The driving device 2, the telescopic support member 3, the driving member 41, the electric telescopic plate, the driving motor 7 and the electric steering wheel 12 are all electrically connected to the control component, and the operator can control the driving device 2, the telescopic support member 3, the driving member 41, the electric telescopic plate, the driving motor 7 and the electric steering wheel 12 by operating the remote controller.
