Its core function is to achieve efficient, safe, and accurate material handling in order to optimize production processes, improve operational efficiency, and reduce labor costs.

[0003] Material transfer lifting equipment typically involves placing the objects to be transferred on a lifting platform. However, existing material transfer lifting equipment lacks a structure for stabilizing and protecting the objects. When transferring objects at a high height, the center of gravity of the objects gradually rises as the equipment lifts them. During the transfer process, the objects are easily tipped over due to bumps in the equipment or on the road, leading to damage. Therefore, a lifting device for material transfer is proposed to solve the above problems. Utility Model Content

One end of the second adjusting rod is rotatably connected to a fixing plate. A lifting drive assembly is provided between the transfer vehicle and the lifting connecting plate.

[0007] Furthermore, the fixing plate is L-shaped, and the two fixing plates correspond to each other.

[0008] Furthermore, the inner side of the connecting frame is provided with two limiting grooves, and the surface of the threaded sleeve is fixedly installed with a limiting slider that slides into the limiting groove.

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 1-4 This embodiment of a lifting device for material transfer includes a transfer vehicle 1. A lifting connecting plate 2 and a counterweight 14 are fixedly installed on the surface of the transfer vehicle 1. A lifting placement plate 3 is slidably installed on the surface of the lifting connecting plate 2. A limiting and fixing component 4 is provided on the lifting connecting plate 2. The limiting and fixing component 4 includes a connecting frame 41 fixedly installed on the opposite side surface of the lifting connecting plate 2. A threaded sleeve 42 is slidably installed inside the connecting frame 41. A first adjusting rod 43 is threadedly connected inside the threaded sleeve 42. A connecting plate 44 is rotatably connected to one end of the first adjusting rod 43. A second adjusting rod 45 is threadedly connected to the surface of the connecting plate 44, penetrating the connecting plate 44. A fixing plate 46 is rotatably connected to one end of the second adjusting rod 45. A lifting drive component 5 is provided between the transfer vehicle 1 and the lifting connecting plate 2.

[0023] In this embodiment, the fixing plate 46 is L-shaped, and the two fixing plates 46 correspond to each other. The L-shaped design makes it easy for the fixing plate 46 to fit with the corners of the object, which can simultaneously achieve clamping, fixing and limiting of the object, and helps to prevent the object from tipping over.

[0024] In this embodiment, two limiting grooves 6 are provided on the inner side of the connecting frame 41, and a limiting slider 7 is fixedly installed on the surface of the threaded sleeve 42 and slidably inserted into the limiting groove 6. By setting the limiting groove 6 and the limiting slider 7, the threaded sleeve 42 can be limited, which can prevent the threaded sleeve 42 from rotating inside the connecting frame 41, which is beneficial to ensure that the first adjusting rod 43 rotates and moves inside the threaded sleeve 42.

[0025] In this embodiment, two guide slide columns 8 are fixedly installed on the surface of the lifting connecting plate 2. A sleeve 9 is slidably sleeved on the surface of the guide slide column 8. The lifting plate 3 is fixedly connected to the sleeve 9. The sleeve 9 facilitates the connection between the lifting plate 3 and the guide slide column 8, and allows the lifting plate 3 to move and rise along the axial direction of the guide slide column 8.

[0026] In this embodiment, the lifting drive assembly 5 includes a connecting frame 51 fixedly installed on the surface of the transfer vehicle 1. A motor 52 is fixedly installed on the outer surface of the connecting frame 51. A take-up roller 53 located inside the connecting frame 51 is fixedly installed at the output end of the motor 52. A steel wire rope 54 is fixedly installed on the surface of the take-up roller 53. A fixed crossbar 55 is fixedly installed on the surface of the lifting platform 3. The end of the steel wire rope 54 away from the take-up roller 53 is fixedly connected to the fixed crossbar 55. By setting the lifting drive assembly 5, the lifting platform 3 can be driven to move and lift.

[0027] In this embodiment, an anti-wear roller 10 is rotatably installed on the top of the lifting connecting plate 2, and the wire rope 54 passes around the top of the lifting connecting plate 2 and comes into contact with the anti-wear roller 10. By setting the anti-wear roller 10, the friction between the wire rope 54 and the top of the lifting connecting plate 2 can be reduced.

[0028] In this embodiment, a bottom support plate 11 is fixedly installed at the bottom of the lifting connecting plate 2, and a moving wheel 12 is rotatably installed on the lower surface of the bottom support plate 11. By setting the bottom support plate 11, it is convenient to support the lifting connecting plate 2 and the lifting storage plate 3, which helps to improve the stability of the lifting equipment.

[0029] In this embodiment, two support columns 13 are fixedly installed on the lower surface of the lifting platform 3. By setting the support columns 13, the lifting platform 3 can be supported when objects are placed, which can prevent the lifting platform 3 from collapsing downward on the side away from the lifting connecting plate 2.

[0030] The working principle of the above embodiments is as follows:

[0031] When transferring materials, place the object to be transferred on the lifting platform 3. After placing the object, rotate the first adjusting rod 43, causing it to rotate inside the threaded sleeve 42 and generate displacement, thereby moving the connecting plate 44 until the fixing plate 46 aligns with the corner of the object away from the lifting connecting plate 2. The operator holds the connecting plate 44 to limit its position. Then, rotate the second adjusting rod 45, causing the fixing plate 46 to move towards the corner of the object away from the lifting connecting plate 2. Rotate the fixing plate 46 again to adjust it so that the L-shaped fixing plate 46 fits with the corner of the object, thus achieving clamping, fixing, and limiting of the object. When it is necessary to lift the object, start the motor 5. 2. After the motor 52 starts, its output end drives the winding roller 53 located inside the connecting frame 51 to rotate. When the winding roller 53 rotates, it will wind or unwind the wire rope 54. When the wire rope 54 is wound, the wire rope 54 pulls the lifting plate 3 upward along the axial direction of the guide column 8 through the fixed crossbar 55. When the wire rope 54 is unwound, the lifting plate 3 descends along the axial direction of the guide column 8 under the action of gravity. The counterweight 14 can balance the center of gravity of the equipment and improve the overall stability of the equipment. During the use of the equipment, the bottom support plate 11 supports the lifting connecting plate 2 and the lifting plate 3, further improving the stability of the lifting equipment and helping to ensure the safe and smooth progress of the material transfer process.
