Specific embodiments

[0016] The technical solutions in the present invention will be further described below in conjunction with the drawings and embodiments.

[0017] Embodiment:

[0018] As Figure 1 and Figure 2As shown in the figure, a single-arm lifting device includes a bottom plate 12. At the top of the bottom plate 12, a column 11 with an installation groove on one side is fixedly installed. A lifting assembly is arranged in the installation groove 16 of the column 11. A horizontal load-carrying plate 35 is arranged on the lifting assembly. A working cavity 15 with an upward opening is formed in the load-carrying plate 35. A stress plate 22 that can move closer to or away from the lifting assembly is slidably arranged in the working cavity 15. At the bottom end of the stress plate 22, a rack 23 with a length direction parallel to the sliding direction of the stress plate 22 is fixedly installed. On one inner wall of the working cavity 15, a driving motor 34 is fixedly installed. At the output end of the driving motor 34, a driving shaft 32 that is horizontal and perpendicular to the sliding direction of the stress plate 22 is arranged. A driving gear 33 that is coaxial with the driving shaft 32 and meshes with the rack 23 is fixedly installed on the driving shaft 32. On both inner walls of the working cavity 15, contact plates 26 that can slide vertically are slidably arranged. The rack 23 is located between the two contact plates 26. The driving shaft 32 is connected to the two contact plates 26 and is used to drive the two contact plates 26 to move up and down. A plurality of inclined warning lights 25 are fixedly installed at the bottom ends of the two contact plates 26. A plurality of communication holes 24 are formed at the bottom end of the working cavity 15. The warning lights 25 are used to extend into the corresponding communication holes 24 as the contact plates 26 move downward. The plurality of indicator lights 25 are connected in parallel, and the plurality of parallel-connected indicator lights 25 are connected with a plug. The plug 27 is fixed at the bottom of one of the contact plates 26. A socket 28 that is vertically opposite to the plug 27 is fixedly installed on the bottom wall of the working cavity 15. After the warning lights 25 enter the communication holes 24, they are activated, and the light of the lifting lights 25 irradiates to the ground, forming two warning belts to remind the staff that the area is a working area and the danger is relatively high.

[0019] As Figure 1 shown, the lifting assembly includes a working motor 18, two contact shafts 13 that are opposite up and down, and two contact wheels 14. The working motor 18 is fixedly installed on one inner wall of the installation groove 16 of the column 11. The two contact shafts 13 are rotatably arranged on the inner wall of the installation groove 16 of the column 11. One of the contact shafts 13 is in power connection with the output end of the working motor 18. The two contact wheels 14 are respectively fixedly sleeved on the two contact shafts 13. A chain 17 is connected between the two contact wheels 14. The load-carrying plate 35 is fixedly installed on the chain 17. By adopting this transmission method, the lifting of goods is realized. The working motor 18 works in an alternating forward and reverse manner, so that the chain 17 rotates clockwise or counterclockwise, and then the load-carrying plate 35 moves up or down. A connecting plate 10 is fixedly installed between the load-carrying plate 35 and the chain 17.

[0020] As Figure 1 and Figure 2As shown, two coaxial winding wheels 36 are fixedly arranged on the driving shaft 32. Thin ropes 38 are wound on both of the two winding wheels 36. The other ends of the two thin ropes 38 are respectively fixedly connected to the tops of two contact plates 26 in a one-to-one correspondence. Four rope winding rods 29 are fixedly arranged on the inner walls of both sides of the working cavity 15. One thin rope 38 sequentially passes around the four rope winding rods 29 on one side of the working cavity 15 and is fixedly connected to the top of one contact plate 26, and the other thin rope 38 sequentially passes around the four rope winding rods 29 on the other side of the working cavity 15 and is fixedly connected to the top of the other contact plate 26. By using the connection method of the thin ropes 38, the lifting of the contact plate 26 is realized, and thus the opening and closing of the lifting lamp 25 are controlled.

[0021] As Figure 1 and Figure 3 As shown, a receiving hole 43 is formed through the front and back of the contact plate 26. A driven shaft 30 is rotatably arranged on the inner wall of the receiving hole 43. One end of the driven shaft 30 extending into the working cavity 15 is fixedly provided with a coaxial driven bevel gear 31. A driving bevel gear 37 meshing with the driven bevel gear 31 is fixedly arranged on the driving shaft 32. One end of the driven shaft 30 in the receiving hole 43 is fixedly provided with a turbine 41. Two front and rear opposite blocking strips 40 are slidably arranged in the receiving hole 43. The two blocking strips 40 can slide in the receiving hole 43 along a direction perpendicular to the sliding direction of the load-carrying plate 35. Threaded rods 39 are fixedly arranged on the opposite end faces of the two blocking strips 40. A hollow rod 42 sleeved on the outer sides of the opposite end parts of the two threaded rods 39 is threadedly connected between the opposite end parts of the two threaded rods 39. A worm meshing with the turbine 41 is fixedly arranged on the outer wall of the hollow rod 42. Blocking grooves 19 adapted to the two blocking strips 40 are formed on the inner walls of the front and rear sides of the installation groove 16 of the column 11. The turbine 41 drives the hollow rod 42 to rotate through the worm. The rotation of the hollow rod 42 drives the two threaded rods 39 to move away from each other. The blocking strips 40 move into the blocking grooves 19 along with the threaded rods 39, thereby restricting the up and down movement of the load-carrying plate 35.

[0022] As Figure 1 As shown, a vertical plate 20 is fixedly arranged on the left side of the top of the load-carrying plate 35. Enclosing plates 21 are fixedly arranged on the front and rear sides of the top of the load-carrying plate 35. The two end faces of the vertical plate 20 are respectively abutted against one side end face of the two enclosing plates 21. The enclosing plates 21 and the vertical plate 20 cooperate to form a semi-closed space, which has a certain blocking effect on the goods placed on the load-carrying plate 35.

[0023] Working principle:

[0024] When the goods need to be transported, first, the goods are conveyed to the force-bearing plate 22 through the conveyor belt. Part of the bottom of the goods does not contact the force-bearing plate 22. Then, the working motor 18 is started. The working motor 18 drives the contact wheel 14 to rotate through the contact shaft 13. The rotation of the contact wheel 14 drives the chain 17 to rotate. The chain 17 drives the load-carrying plate 35 to move upward through the connecting plate 10. The load-carrying plate 35 drives the force-bearing plate 22 to move upward, and the force-bearing plate 22 drives the goods to move upward. When the goods move to the corresponding height, the transmission motor 34 is started. The transmission motor 34 drives the driving shaft 32 to rotate. The driving shaft 32 drives the rack 23 to move through the transmission gear 33. The rack 23 drives the force-bearing plate 22 to move, and the force-bearing plate 22 drives the goods to move. The goods move in the direction away from the column 11. The bottom end of the goods that does not contact the force-bearing plate 22 abuts against the bottom end of another conveyor belt. The conveyor belt drives the goods to leave the force-bearing plate 22. The rotation of the driving shaft 32 drives the wire winding wheel 36 to rotate. The wire 28 is relaxed when the wire winding wheel 36 rotates. The contact plate 26 moves downward under the action of gravity. The contact plate 26 drives the warning light 25 to move downward. The warning light 25 moves downward and enters the communication hole 24. After completion, the working motor 18 drives the load-carrying plate 35 to move downward.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
