Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery module transfer carts, specifically a lithium battery module transfer cart with a clamping and self-locking function. Background Technology

[0002] In utility model patent application CN220996429U, published on May 24, 2024, entitled "Module Transfer Cart," this utility model relates to the field of lithium battery production technology and discloses a module transfer cart. The module transfer cart provided by this utility model includes a frame body and a lifting assembly. A plurality of loading support plates are spaced apart along a first direction on the frame body, and these loading support plates are on the same horizontal plane. The loading support plates extend along a second direction of the frame body, and the second direction is perpendicular to the first direction. The lifting assembly is disposed on the frame body and connected to the loading support plates. The lifting assembly is configured to push the loading support plates to rise or fall, so that the modules to be transferred rise to a first position above the conveyor belt surface, or fall to a second position level with or below the conveyor belt surface. Compared with manual handling, this module transfer cart reduces labor costs and significantly improves production efficiency.

[0003] In the prior art including the aforementioned patents, battery modules may slide or shift during transport due to the starting, stopping, turning, or road bumps of the trolley. Lithium battery modules stacked on the transport trolley may move, collide, or even fall during transport. Module sliding may cause safety risks. Therefore, it is necessary to design a lithium battery module transport trolley with a clamping and self-locking function. Utility Model Content

[0004] The purpose of this utility model is to provide a lithium battery module transport trolley with a clamping and self-locking function to solve the problem mentioned in the background art that the battery module may slide or shift during the transport process due to the start, stop, turn or road bumps of the trolley.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery module transfer trolley with a pressing and self-locking function, comprising a frame, a push rod installed on one side of the frame, a lifting assembly installed on the top of the frame, a pressing and self-locking assembly installed on the top of the frame via the lifting assembly, a wheel frame fixedly connected to the bottom of the frame, a buffer member fixedly connected to the outer wall of the wheel frame, a triangular rotating wheel installed on the bearing of the outer wall of the wheel frame, a crossbar fixedly connected to the inner wall of the lifting assembly, a telescopic sleeve connected to the outer wall of the crossbar, and a limit plate fixedly connected to one end of the telescopic sleeve.

[0006] Furthermore, the lifting assembly includes a support frame, a lifting cylinder, a lifting frame, and a lifting platform. The support frame is fixedly connected to the inner wall of the vehicle frame. The lifting cylinder is connected to the internal shaft of the support frame. The lifting frame is installed at the output end of the lifting cylinder. The lifting platform is connected to the top shaft of the lifting frame.

[0007] Furthermore, the lifting frame is connected to the inner wall of the vehicle frame via a pivot, and the lifting frame is connected to the self-locking clamping assembly via the pivot.

[0008] Furthermore, the internal components of the self-locking clamping assembly include bushings, tension plates, clamping rubber rollers, and elastic ropes. Bushings are installed at both ends of the central shaft of the lifting frame. Tension plates are fixedly connected to the outer walls of the bushings. Clamping rubber rollers are slidably installed inside the tension plates. An elastic rope is provided at one end of the clamping rubber rollers.

[0009] Furthermore, the traction plates are positioned on both sides of the lifting platform, and the traction plates can rotate at an angle of 90°.

[0010] Furthermore, the outer wall of the bushing is provided with protrusions, and an elastic rope is wound around the outside of the protrusions.

[0011] Furthermore, the wheel frame is provided in four sets, and the wheel frame in the forward direction of the frame is fixed at the bottom of the frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the lithium battery module transfer trolley with clamping and self-locking function is reasonable and has the following advantages:

[0013] (1) The clamping self-locking component set by this device can limit the lithium battery modules stacked above. As the battery modules may slide or shift during the transfer process due to the starting, stopping, turning or road bumps of the trolley, the clamping self-locking component can firmly fix the lithium battery modules on the transfer trolley. While the lifting cylinder drives the lifting frame to descend and transfer, the pulling plate is driven by the force of the rotation of the lifting frame, so that it is placed vertically. After placement, the clamping rubber roller is affected by gravity and comes into contact with the lithium battery module. It is fixed by elastic rope and limited by the pressure above to prevent it from moving, colliding or even falling during the transportation process, thereby ensuring the safety of the transportation process and reducing the risk of safety accidents caused by module sliding.

[0014] (2) The triangular turning wheels designed at the bottom of the frame move around. In addition to the advantages of ordinary turning wheels, they also have the benefits of dealing with special terrain, improving transfer efficiency and enhancing stability. The triangular design of the turning wheels allows them to rotate forward by using the corners as fulcrums when going up stairs, which can effectively reduce the difficulty of climbing stairs and make the cart easily cross the steps. This solves the problem that ordinary wheels cannot move on stair terrain and greatly expands the scope of use of the transfer cart. It can complete the transfer of lithium battery modules more efficiently in workshops, warehouses and other places with stairs. When encountering uneven road surfaces such as potholes and bumps, the three corners of the triangular wheels can better adapt to the changes in the road surface. Compared with ordinary round wheels, it has more contact points with the ground and is easier to find a stable support point, thereby reducing the bumps and jams caused by uneven road surfaces and making the cart move more smoothly.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0023] Example 1:

[0024] A lithium battery module transfer trolley with a clamping self-locking function includes a frame 1, a push rod 2 installed on one side of the frame 1, a lifting assembly 3 installed on the top of the frame 1, a clamping self-locking assembly 4 installed on the top of the frame 1 via the lifting assembly 3, a wheel frame 5 fixedly connected to the bottom of the frame 1, a buffer 6 fixedly connected to the outer wall of the wheel frame 5, a triangular rotating wheel 7 installed on the outer wall bearing of the wheel frame 5, a crossbar 8 fixedly connected to the inner wall of the lifting assembly 3, a telescopic sleeve 9 connected to the outer wall pivot of the crossbar 8, and a limit plate 10 fixedly connected to one end of the telescopic sleeve 9.

[0025] The above structure, through the clamping self-locking component 4 set in this device, can limit the lithium battery modules stacked above. Because the battery modules may slide or shift during the transfer process due to the starting, stopping, turning of the trolley or road bumps, the clamping self-locking component 4 can firmly fix the lithium battery modules on the transfer trolley.

[0026] Furthermore, the lifting assembly 3 includes a support frame 301, a lifting cylinder 302, a lifting frame 303, and a lifting platform 304. The support frame 301 is fixedly connected to the inner wall of the frame 1. The lifting cylinder 302 is connected to the internal shaft of the support frame 301. The lifting frame 303 is installed at the output end of the lifting cylinder 302. The lifting platform 304 is connected to the top shaft of the lifting frame 303. The lifting frame 303 is connected to the inner wall of the frame 1 by a shaft, and the lifting frame 303 is connected to the self-locking clamping assembly 4 through a shaft.

[0027] The above structure uses the lifting cylinder 302 to drive the lifting frame 303 to descend, thereby driving the lifting platform 304 to lift and transfer.

[0028] Furthermore, the internal components of the self-locking clamping assembly 4 include a bushing 401, a tension plate 402, a clamping rubber roller 403, and an elastic rope 404. Bushings 401 are installed at both ends of the central shaft of the lifting frame 303. The tension plate 402 is fixedly connected to the outer wall of the bushing 401. The clamping rubber roller 403 is slidably installed inside the tension plate 402. An elastic rope 404 is provided at one end of the clamping rubber roller 403. The tension plate 402 is located on both sides of the lifting platform 304, and the rotatable angle of the tension plate 402 is 90°. The outer wall of the bushing 401 is provided with protrusions, and the elastic rope 404 is wrapped around the outside of the protrusions.

[0029] The aforementioned structure utilizes the lifting cylinder 302 to drive the lifting frame 303 for downward transport, while simultaneously causing the traction plate 402 to be vertically positioned due to the rotational force of the lifting frame 303. After placement, the pressure rubber roller 403, under the influence of gravity, comes into contact with the lithium battery module and is secured by an elastic rope 404. The overhead pressure provides a limit, preventing movement, collision, or even falling during transport, thus ensuring safety during the transportation process.

[0030] Furthermore, the wheel frame 5 is provided with four sets, and the wheel frame 5 in the forward direction of the frame 1 is fixed at the bottom of the frame 1.

[0031] The aforementioned structure, with its three corners forming the triangular rotating wheel 7, can better adapt to changes in road surface conditions. Compared to ordinary circular wheels, it has more contact points with the ground, making it easier to find stable support points.

[0032] Working principle: In use, firstly, the self-locking clamping component 4 of this device can limit the lithium battery modules stacked above. Because the battery modules may slide or shift during the transfer process due to the starting, stopping, turning of the trolley or road bumps, the self-locking clamping component 4 can firmly fix the lithium battery modules on the transfer trolley. At the same time, the lifting cylinder 302 drives the lifting frame 303 to descend and transfer, so that the traction plate 402 is driven by the rotation force of the lifting frame 303, thus placing it vertically. After placement, the clamping rubber roller 403 is affected by gravity and comes into contact with the lithium battery module. It is fixed by the elastic rope 404. The pressure from above limits the movement, preventing it from moving, colliding, or even falling during transportation, thus ensuring the safety of the transportation process and reducing the risk of safety accidents caused by module slippage.

[0033] Secondly, when the lifting platform 304 is in the raised state, it can be used for material transfer and unloading operations, and the self-locking component 4 is biased to one side. When it is in the lowered state, it is used for transportation operations and can be used for self-locking operations.

[0034] Finally, the vehicle moves using the triangular rotating wheels 7 designed at the bottom of the frame 1. In addition to the advantages of ordinary rotating wheels, it also offers benefits in dealing with special terrain, improving transfer efficiency, and enhancing stability. The triangular design of the triangular rotating wheels 7 allows them to rotate and move forward by using the corners as fulcrums when going up stairs, which can effectively reduce the difficulty of climbing stairs and allow the vehicle to easily cross steps. This solves the problem that ordinary wheels cannot move on stair terrain and greatly expands the application range of the transfer vehicle.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
