It solves the problem that existing transfer and protection devices for the sale of mechanical equipment require two lifting plates to pass through the bottom of the equipment and lift the equipment with a hydraulic cylinder before a bearing plate can be placed to support the equipment. This loading process is time-consuming and labor-intensive, affecting the efficiency of equipment transfer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transfer device for selling mechanical equipment, comprising a U-shaped trolley, wherein a load-bearing component is provided on the inner side of the U-shaped trolley, and lifting mechanisms are provided on both the left and right sides of the U-shaped trolley. The lifting mechanism includes a drive assembly, and the drive assembly has connecting components on both sides of the side closest to the U-shaped trolley. The U-shaped trolley has rectangular through holes on both the left and right sides of its inner wall for use with connecting components.

[0007] As a preferred embodiment of the present invention, the bearing component includes a limiting plate, and a bearing plate is fixedly connected to the front side of the limiting plate. Connection holes are provided on both the left and right sides of the bearing plate.

[0008] As a preferred embodiment of this utility model, T-shaped blocks are fixedly connected to the left and right sides of the rear side of the limiting plate, and T-shaped grooves are opened on both sides of the rear side of the inner wall of the U-shaped trolley. The rear side of the T-shaped block is located in the inner cavity of the T-shaped groove and contacts the inner wall of the T-shaped groove.

[0009] As a preferred embodiment of the present invention, the driving assembly includes a hydraulic cylinder, the side of the hydraulic cylinder near the U-shaped trolley is fixedly connected to the U-shaped trolley, the output shaft of the hydraulic cylinder is fixedly connected to a lifting plate, and the left and right sides of the lifting plate are both fixedly connected to pressing blocks.

[0010] As a preferred embodiment of this invention, extrusion holes are provided on both the front and rear sides of the inner wall of the extrusion block.

[0011] In a preferred embodiment of this utility model, the connecting assembly includes a limiting block, a limiting post, and a positioning block. The limiting block is located in the inner cavity of the rectangular through hole and contacts the inner wall of the rectangular through hole. The bottom of the limiting post is fixedly connected to the limiting block, and the top of the limiting post penetrates through the rectangular through hole and extends to the outer side of the rectangular through hole and is fixedly connected to the positioning block. A spring is sleeved on the surface of the limiting post, and the top and bottom of the spring are fixedly connected to the inner wall of the rectangular through hole and the limiting block, respectively.

[0012] As a preferred embodiment of this utility model, a push plate is provided on the left side of the limiting block, the push plate is located inside the extrusion block, and extrusion columns are fixedly connected to the top of the front and rear sides, and a connecting column is fixedly connected to the bottom of the right side of the push plate. The side of the extrusion column away from the push plate is located in the inner cavity of the extrusion hole and contacts the inner wall of the extrusion hole. The right side of the connecting column passes through the limiting block and extends to the outside of the limiting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model solves the problem that existing mechanical equipment sales transfer protection devices require two lifting plates to pass through the bottom of the equipment and lift it with a hydraulic cylinder before the load-bearing plate can be placed to support the equipment. This loading process is time-consuming and labor-intensive, affecting the efficiency of equipment transfer. The present invention achieves the effect of facilitating the loading and unloading of equipment and improving the efficiency of equipment transfer.

[0014] 2. By setting up a load-bearing component, this utility model utilizes the cooperation of a limiting plate with the T-shaped block and T-shaped groove of a U-shaped trolley to precisely guide the movement trajectory of the load-bearing plate, preventing it from deviating. At the same time, the load-bearing plate can directly support mechanical equipment, and its connecting holes can cooperate with the connecting columns of the connecting component to achieve a stable linkage between the load-bearing component and the lifting mechanism, ensuring that the equipment does not shake when lifted and improving the safety of transportation.

[0015] 3. This utility model, by setting up a drive component, uses a hydraulic cylinder as a power source, and the output force is stable and controllable. It can drive the two sides of the extrusion blocks to move synchronously through the lifting plate, ensuring that the lifting force on the left and right sides is balanced and avoiding the equipment from tilting due to uneven force on one side. The extrusion hole of the extrusion block cooperates with the extrusion column of the connecting component, which can convert the vertical power of the hydraulic cylinder into the horizontal power to push the connecting component.

[0016] 4. By setting up a connecting component, the elastic potential energy of the spring can apply continuous downward pressure to the limiting block, so that in the initial stage of the extrusion block rising, it only pushes the connecting column to move and dock with the bearing component, while the limiting block remains stationary. When the extrusion column slides to the end of the extrusion hole, the extrusion block then drives the limiting block and the bearing component to rise synchronously through the connecting column, avoiding conflict between the components. The limiting column and the positioning block can limit the movement range of the limiting block, prevent the component from dislodging from the rectangular through hole, and ensure that the entire lifting process is stable and reliable. At the same time, the spring can realize the automatic reset of the connecting component without manual adjustment. Attached Figure Description

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0023] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention, which provides a transfer device for the sale of mechanical equipment, including a U-shaped trolley 1, a load-bearing component 2 provided on the inner side of the U-shaped trolley 1, and lifting mechanisms 3 provided on both the left and right sides of the U-shaped trolley 1. The lifting mechanism 3 includes a drive assembly 31, and connecting assemblies 32 are provided on both sides of the drive assembly 31 on the side closest to the U-shaped trolley 1. The U-shaped trolley 1 has rectangular through holes 4 on both the left and right sides of its inner wall, which are used in conjunction with the connecting component 32.

[0024] Specifically, by setting up the bearing component 2 and the lifting mechanism 3 in combination, the problem of the existing mechanical equipment sales transfer protection device, which requires two lifting plates to pass through the bottom of the equipment and lift the equipment through the hydraulic cylinder 311 before the bearing plate 22 can be placed to support the equipment, is solved. The loading process is time-consuming and labor-intensive, which affects the efficiency of equipment transfer. The solution achieves the effect of facilitating the loading and unloading of equipment and improving the efficiency of equipment transfer.

[0025] Furthermore, when it is necessary to transfer the equipment, push the U-shaped trolley 1 to a suitable position so that the supporting component 2 passes through the bottom of the equipment. Then, start the output shaft of the drive component 31 to retract, first drive the connecting component 32 to insert into the supporting plate 22 of the supporting component 2, and then drive the equipment to rise through the connecting component 32 so that the support feet at the bottom of the equipment no longer contact the ground, making it easier for the user to transfer the equipment. Once the equipment is moved to a suitable location, the output shaft of the hydraulic cylinder 311 of the drive assembly 31 extends and drives the connecting assembly 32 to move down, allowing the equipment on the support assembly 2 to be lowered. After the equipment's legs contact the ground, the drive assembly 31 will drive the connecting assembly 32 to disconnect from the support assembly 2, making it easier for the U-shaped trolley 1 to be moved away.

[0026] Example 2 In the second embodiment of this utility model, the bearing component 2 includes a limiting plate 21, and a bearing plate 22 is fixedly connected to the front side of the limiting plate 21. Connecting holes 23 are provided on both the left and right sides of the bearing plate 22.

[0027] T-shaped blocks 5 are fixedly connected to the left and right sides of the rear side of the limiting plate 21. T-shaped grooves 6 are opened on both sides of the rear side of the inner wall of the U-shaped trolley 1. The rear side of the T-shaped block 5 is located in the inner cavity of the T-shaped groove 6 and is in contact with the inner wall of the T-shaped groove 6.

[0028] Specifically, by setting up the bearing component 2, and using the limit plate 21 in conjunction with the T-shaped block 5 and T-shaped groove 6 of the U-shaped trolley 1, the movement trajectory of the bearing plate 22 can be precisely guided to prevent the bearing plate 22 from deviating. At the same time, the bearing plate 22 can directly support the mechanical equipment, and its connecting hole 23 can cooperate with the connecting column 10 of the connecting component 32 to achieve stable linkage between the bearing component 2 and the lifting mechanism 3, ensuring that the equipment does not shake when lifted and improving the safety of transportation.

[0029] Furthermore, in the initial state, the T-shaped block 5 of the bearing component 2 is located at the bottom of the T-shaped groove 6, and the bearing plate 22 is close to the bottom of the U-shaped trolley 1. When it is necessary to support the equipment, the operator pushes the limiting plate 21. The limiting plate 21 drives the T-shaped block 5 on the rear side to slide along the inner wall of the T-shaped groove 6. The T-shaped groove 6 limits the T-shaped block 5 to only move up and down, preventing the bearing plate 22 from shifting left and right. The bearing plate 22 moves synchronously with the limiting plate 21 and extends into the bottom from the side of the equipment. When the connecting post 10 of the connecting component 32 is inserted into the connecting hole 23 of the bearing plate 22, the bearing component 2 and the lifting mechanism 3 are linked. When the lifting mechanism 3 is activated, the connecting post 10 pulls the bearing plate 22, and the bearing plate 22 drives the limiting plate 21 to move synchronously. The T-shaped block 5 slides upward along the T-shaped groove 6 to ensure that the bearing component 2 is always lifted in the vertical direction, so as to lift the equipment and facilitate the movement of the equipment. After the equipment is transferred, the connecting column 10 disengages from the connecting hole 23, and pushing the limiting plate 21 will drive the bearing component 2 to reset to the initial position along the T-groove 6, ready for the next use.

[0030] Example 3 In the third embodiment of this utility model, the drive assembly 31 includes a hydraulic cylinder 311. The side of the hydraulic cylinder 311 closest to the U-shaped trolley 1 is fixedly connected to the U-shaped trolley 1. The output shaft of the hydraulic cylinder 311 is fixedly connected to a lifting plate 312. The left and right sides of the lifting plate 312 are both fixedly connected to pressing blocks 313.

[0031] Extrusion holes 7 are provided on the front and rear sides of the inner wall of the extrusion block 313.

[0032] Specifically, by setting up the drive component 31, with the hydraulic cylinder 311 as the power source, the output force is stable and controllable. The lifting plate 312 can synchronously drive the two sides of the extrusion blocks 313 to move, ensuring that the lifting force on the left and right sides is balanced and avoiding the equipment from tilting due to uneven force on one side. The extrusion hole 7 of the extrusion block 313 cooperates with the extrusion column 9 of the connecting component 32, which can convert the vertical power of the hydraulic cylinder 311 into the horizontal power to push the connecting component 32.

[0033] Furthermore, when it is necessary to drive the lifting action, the output shaft of the hydraulic cylinder 311 retracts, driving the lifting plate 312 to rise in the vertical direction, and the lifting plate 312 simultaneously drives the pressing blocks 313 on the left and right sides to rise. The extrusion hole 7 on the inner wall of the extrusion block 313 contacts the extrusion column 9 of the connecting assembly 32. The inclined inner wall of the extrusion hole 7 generates a horizontal thrust on the extrusion column 9 towards the inside of the U-shaped trolley, pushing the extrusion column 9 to slide along the extrusion hole 7, thereby driving the push plate 8 of the connecting assembly 32 to move synchronously with the connecting column 10, so that the connecting column 10 is inserted into the inner cavity of the connecting hole 23. Then, as the extrusion block 313 continues to rise, it will drive the connecting component 32 and the bearing component 2 to rise, and compress the spring 324, so that the support feet at the bottom of the equipment no longer contact the ground, making it easier for the user to move the equipment. When a descent is required, the output shaft extends, causing the lifting plate 312 and the pressing block 313 to descend, and simultaneously causing the connecting assembly 32 and the bearing assembly 2 to move downward. After the support legs of the equipment contact the ground, the pressing block 313 continues to move downward a certain distance, and the reverse thrust generated on the pressing column 9 causes the connecting column 10 in the connecting assembly 32 to be pulled out from the inner cavity of the connecting hole 23, making it easy for the user to remove the U-shaped trolley 1.

[0034] Example 4 In the fourth embodiment of this utility model, the connecting component 32 includes a limiting block 321, a limiting post 322, and a positioning block 323. The limiting block 321 is located in the inner cavity of the rectangular through hole 4 and contacts the inner wall of the rectangular through hole 4. The bottom of the limiting post 322 is fixedly connected to the limiting block 321. The top of the limiting post 322 penetrates the rectangular through hole 4 and extends to the outside of the rectangular through hole 4 and is fixedly connected to the positioning block 323. A spring 324 is sleeved on the surface of the limiting post 322. The top and bottom of the spring 324 are fixedly connected to the inner wall of the rectangular through hole 4 and the limiting block 321, respectively.

[0035] A push plate 8 is provided on the left side of the limiting block 321. The push plate 8 is located inside the extrusion block 313, and extrusion columns 9 are fixedly connected to the top of the front and rear sides. A connecting column 10 is fixedly connected to the bottom of the right side of the push plate 8. The side of the extrusion column 9 away from the push plate 8 is located in the inner cavity of the extrusion hole 7 and is in contact with the inner wall of the extrusion hole 7. The right side of the connecting column 10 passes through the limiting block 321 and extends to the outside of the limiting block 321.

[0036] Specifically, by setting the connecting component 32, the elastic potential energy of the spring 324 can apply continuous downward pressure to the limiting block 321, so that in the initial stage of the extrusion block 313 rising, it only pushes the connecting column 10 to move and dock with the bearing component 2, while the limiting block 321 remains stationary. When the extrusion column 9 slides to the end of the extrusion hole 7, the extrusion block 313 then drives the limiting block 321 and the bearing component 2 to rise synchronously through the connecting column 10, avoiding component movement conflict. The limiting column 322 and the positioning block 323 can limit the movement range of the limiting block 321, prevent the component from dislodging from the rectangular through hole 4, and ensure that the entire lifting process is stable and reliable. At the same time, the spring 324 can realize the automatic reset of the connecting component 32 without manual adjustment.

[0037] Furthermore, when the extrusion block 313 rises, the inner wall of the extrusion hole 7 generates an inward thrust on the extrusion column 9. The extrusion column 9 drives the push plate 8 to move synchronously. The push plate 8 pushes the connecting column 10 through the limiting block 321 and extends inward until the connecting column 10 is inserted into the connecting hole 23 of the bearing plate 22, thus completing the docking of the connecting component 32 and the bearing component 2. As the extrusion block 313 continues to rise, the extrusion column 9 slides to the end of the extrusion hole 7. The thrust of the extrusion block 313 overcomes the pressure of the spring 324 and drives the limiting block 321 to move upward along the rectangular through hole 4 through the pushing plate 8 and the connecting column 10. The limiting block 321 drives the limiting column 322 to move synchronously, and the spring 324 is further compressed. During the movement of the limit block 321, the connecting column 10 pulls the bearing component 2 to lift synchronously with the equipment; When a reset is required, the compression block 313 descends, and the spring 324 releases its elastic potential energy, causing the limit block 321 to move down synchronously with the compression block 313, thus lowering the equipment. Once the equipment's legs contact the ground, the limit block 321 stops moving, while the compression block 313 continues to move down a certain distance. At this point, the compression hole 7 generates a reverse thrust on the compression column 9, causing the connecting column 10 to disengage from the connecting hole 23 of the bearing plate 22, pushing the plate 8 and the compression column 9 back to their initial positions with the limit block 321, awaiting the next docking.

[0038] Working principle: During operation, the trolley is pushed to the side of the equipment to be transferred. The operator pushes the U-shaped trolley 1, and the limiting plate 21 of the bearing component 2 drives the bearing plate 22 to extend from the side of the equipment to the bottom, supporting the equipment smoothly and completing the initial docking of the bearing component 2 with the equipment. Then, the hydraulic cylinder 311 of the drive assembly 31 is activated. The output shaft of the hydraulic cylinder 311 retracts, driving the lifting plate 312 and the left and right extrusion blocks 313 to rise synchronously. The inclined extrusion hole 7 on the inner wall of the extrusion block 313 contacts the extrusion column 9 of the connecting assembly 32, generating a horizontal thrust towards the inside of the U-shaped trolley 1. Under the action of the thrust, the extrusion column 9 drives the push plate 8 to move. The push plate 8 pushes the connecting column 10 through the limit block 321 and extends inward until the connecting column 10 is inserted into the connecting hole 23 of the bearing plate 22. During this stage, the downward pressure of the spring 324 keeps the limit block 321 stationary, while only the connecting post 10 moves, ensuring that the connecting post 10 is accurately aligned. The extrusion block 313 continues to rise. When the extrusion column 9 slides to the end of the extrusion hole 7, the thrust of the extrusion block 313 overcomes the pressure of the spring 324. Through the push plate 8 and the connecting column 10, the limiting block 321 and the bearing plate 22 of the bearing assembly 2 rise synchronously. The T-shaped block 5 slides upward along the T-shaped groove 6. The equipment is lifted smoothly with the bearing plate 22 until the bottom support of the equipment is completely off the ground, which makes it convenient for the user to transfer the equipment. Push the trolley to transfer the equipment to the target location. The omnidirectional wheels at the bottom of the trolley can turn flexibly to adapt to the path requirements of different scenarios such as warehouses, showrooms, and sales stores, and the equipment does not need to be lifted by humans throughout the process. After the equipment is unloaded and reaches the target position, the output shaft of the hydraulic cylinder 311 extends, driving the lifting plate 312 and the extrusion block 313 to descend. The spring 324 releases elastic potential energy, pushing the limit block 321 to slide downward along the rectangular through hole 4. The bearing component 2 descends synchronously with the equipment. After the equipment legs touch the ground, the extrusion block 313 continues to descend a certain distance. The inner wall of the extrusion hole 7 generates a reverse thrust on the extrusion column 9, which drives the connecting column 10 to be pulled out from the connecting hole 23 of the bearing plate 22, disconnecting the linkage between the connecting component 32 and the bearing component 2. Finally, the U-shaped trolley 1 is pushed to move the bearing component 2 out from the bottom of the equipment, completing the unloading.

[0039] In summary, by using the load-bearing component 2 and the lifting mechanism 3 in combination, the equipment can be easily loaded and unloaded, and the efficiency of equipment transportation can be improved.
