The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please see Figure 1-3In this embodiment of the utility model, a small component lifting and handling device includes a top plate 10, a lifting structure at the bottom of the top plate 10, and side plates 9 fixedly connected to both sides of the bottom of the top plate 10. Two sliding grooves 7 are formed on the side walls of each side plate 9, and receiving plates 1 are slidably connected to the side walls of each side plate 9. The two receiving plates 1 are respectively connected to the two sliding grooves 7 on the side walls of the two side plates 9. Two limiting plates 20 are fixedly connected to the top of each of the two receiving plates 1, and the four limiting plates 20 are respectively slidably connected to the four sliding grooves 7. Each of the eight limiting plates 20 has two rotating rods 17 rotatably connected to its top. Each of the eight rotating rods 17 has a rotating block 16 fixedly connected to its top. Each of the eight rotating rods 17 has an external thread on its lower outer ring sidewall. Each of the eight receiving plates 1 has eight threaded grooves 19 on its top. The bottom of each of the eight rotating rods 17 is threaded into the eight threaded grooves 19. Each of the two receiving plates 1 has two connecting rods 21 fixedly connected to its bottom. Each of the four connecting rods 21 has a universal wheel 18 at its bottom and on both sides of the bottom of the two side plates 9. Each of the two side plates 9 has a limiting structure on its sidewall.

[0025] Please see Figure 2-3 The lifting structure includes a motor 12, which is fixedly connected to the bottom side wall of the top plate 10. Two baffles 15 are fixedly connected to the bottom of the top plate 10. One end of the output shaft of the motor 12 is fixedly connected to a winding rod 13. The winding rod 13 passes through the left baffle 15 and is rotatably connected to the left baffle 15. One end of the winding rod 13 is rotatably connected to the side wall of the right baffle 15. A pull rope 14 is wound around the outer side wall of the winding rod 13. One end of the pull rope 14 is equipped with a hook 8. The pull rope 14 is made of steel wire rope. The device is moved above the building component. The component is hung on the hook 8, and then the motor 12 is started. The output shaft of the motor 12 drives the winding rod 13 to rotate. When the winding rod 13 rotates, it can wind up or lower the pull rope 14. Thus, the rotation of the winding rod 13 drives the pull rope 14 to wind up, thereby lifting the component.

[0026] Please see Figure 1-3Both limiting structures include mounting plates 4, which are fixedly connected to the side walls of the two side plates 9. Limiting rods 3 are slidably connected to the top of each mounting plate 4, and pull blocks 6 are fixedly connected to the top of each limiting rod 3. Springs 5 ​​are sleeved on the outer side walls of each limiting rod 3, and both ends of each spring 5 are fixedly connected to the corresponding pull blocks 6 and the side walls of the corresponding mounting plates 4. One end of each limiting rod 3 passes through the corresponding mounting plate 4. Limiting holes 22 are formed on the side walls of both receiving plates 1, and one end of each limiting rod 3 extends into the two limiting holes 22. By lifting the pull block 6, the pull block 6 moves the limiting rod 3, causing one end of the limiting rod 3 to disengage from the limiting hole 22. Pulling the support plate 1 causes the two support plates 1 to move back to back. Under the action of the spring 5, the top of the limiting rod 3 will always be pressed against the top side wall of the support plate 1. Then, the device is moved above the building component, and the component is hung on the hook 8 for lifting. Then, by pushing the support plate 1, the two support plates 1 are brought closer to each other. When the limiting hole 22 on the top of the support plate 1 moves below the limiting rod 3, the spring 5 will drive the limiting rod 3 to automatically reset, so that one end of the limiting rod 3 enters the limiting hole 22, thereby fixing the two support plates 1. The two support plates 1 can support the bottom of the component, thereby preventing the component from shaking and falling during transportation and improving the safety of the component during transportation.

[0027] Please see Figure 1-3 A rectangular barrier 11 is fixedly connected to the top of the top plate 10. When items are placed on the top of the top plate 10, the rectangular barrier 11 can cover the items and prevent them from falling.

[0028] Please see Figure 1-3 Both support plates 1 are fixedly connected to handles 2 on their side walls. Both handles 2 have anti-slip textures on their surfaces. The support plates 1 can be moved by pulling the handles 2, which is more convenient.

[0029] The working principle of this utility model is as follows: When the device is needed, firstly, the upper lifting block 6 is used to move the limiting rod 3, causing one end of the limiting rod 3 to disengage from the limiting hole 22. This allows the receiving plate 1 to be pulled so that the two receiving plates 1 move in opposite directions. The top of the limiting rod 3 will always be pressed against the top side wall of the receiving plate 1 under the action of the spring 5. Then, the device is moved above the building component. By hanging the component on the hook 8, the motor 12 is started. The output shaft of the motor 12 drives the winding rod 13 to rotate. When the winding rod 13 rotates, it can pull the rope 14. The component is lifted by rotating the winding rod 13 to drive the pull rope 14 to wind up or lower it. Then, by pushing the support plates 1, the two support plates 1 are brought closer together. When the limiting hole 22 at the top of the support plate 1 moves below the limiting rod 3, the spring 5 will drive the limiting rod 3 to automatically reset, so that one end of the limiting rod 3 enters the limiting hole 22, thereby fixing the two support plates 1. The two support plates 1 can support the bottom of the component, thereby preventing the component from shaking and falling during transportation and improving the safety of the component during transportation.
