On the outer wall of the second linkage shaft on one side of the first driven sprocket, a second driving sprocket is fixed. On the outer wall of the first linkage shaft above the second driving sprocket, a second driven sprocket is fixed. A second chain is wound around the outer walls between the second driven sprocket and the second driving sprocket.

[0006] Preferably, on the top end of the base frame on one side of the first bearing seat, there is a support plate. On the top end of the support plate, there is a top plate. Through the setting of the top plate, it is convenient to place and process the spring telescopic member.

[0007] Preferably, below the top plate, there is a brush plate. The bottom end of the brush plate touches the outer wall of the rope. At the top end of the brush plate, there are spring telescopic members arranged at equal intervals. The top ends of the spring telescopic members are connected to the bottom end of the top plate.

Moreover, it reduces the phenomenon of slippage during the lifting of the construction basket to ensure the safety of the hoist during use;

[0012] (1) The first driving sprocket is driven to rotate by the motor. Since the diameter of the first driving sprocket is smaller than that of the first driven sprocket, the first driving sprocket drives the first driven sprocket to rotate slowly through the first chain, and the first driven sprocket drives the second driving sprocket to rotate synchronously through the second linkage shaft. Also, since the diameter of the second driving sprocket is smaller than that of the second driven sprocket, the second driving sprocket drives the second driven sprocket to rotate further slowly through the second chain, so that the second driven sprocket drives the drum to rotate slowly through the first linkage shaft, and then it is easy for the drum to slowly electrically wind the rope, thereby easily slowly and smoothly lifting the object to improve the lifting effect of the hoist on the object;

[0013] (2) Downward elastic pressure is applied to the brush plate through multiple spring expansion and contraction members, causing the brush plate to move downward and elastically contact the outer wall of the rope. When the drum winds and unwinds the rope, the brush plate will brush and clean the outer wall of the rope, thus achieving the purpose of removing stains on the outer wall of the rope to improve the cleanliness of the rope;

[0014] (3) Elastic pressure is applied to the abutting rod through the return spring, so that one end of the abutting rod always abuts against the inner wall of the abutting block. When the lifting hook hooks the basket carried by the building component, the lifting hook can lock and hook the basket for lifting, thereby reducing the phenomenon of slippage during the lifting of the construction basket to ensure the safety of the hoist during use.

[0024] During use, through the setting of the brush plate 19, the outer wall of the rope 12 can be brushed and cleaned.

[0025] A drum 6 is rotatably installed on the inner wall of the first bearing block 7. A rope 12 is wound around the outer wall of the drum 6. One end of the rope 12 is provided with a lifting hook 21. An abutting block 24 is provided on the inner wall on one side of the lifting hook 21;

[0026] During use, through the setting of the lifting hook 21, the building basket of building materials can be hooked and processed.

[0027] An abutting rod 22 is rotatably installed on the outer wall of the lifting hook 21. One end of the abutting rod 22 away from the lifting hook 21 abuts against the inner wall of the abutting block 24. A return spring 23 is installed on the inner wall of the abutting rod 22. One end of the return spring 23 away from the abutting rod 22 is connected to the inner wall of the lifting hook 21;

[0028] During use, through the arrangement of the reset spring 23, one end of the abutting rod 22 abuts against the inner wall of the abutting block 24;

[0029] One end of the winding drum 6 away from the first bearing seat 7 is provided with a first linkage shaft 9. One end of the first linkage shaft 9 away from the winding drum 6 is rotatably installed with a second bearing seat 8. The bottom end of the second bearing seat 8 is connected to the top end of the base frame 1. One side of the bottom of the base frame 1 is provided with a motor 2 through a bracket. One end of the motor 2 is provided with a first driving sprocket 13. On the inner wall of the base frame 1 above the first driving sprocket 13, a fourth bearing seat 18 is installed. A second linkage shaft 15 is rotatably installed on the inner wall of the fourth bearing seat 18. One end of the second linkage shaft 15 away from the fourth bearing seat 18 is rotatably installed with a third bearing seat 16. The bottom end of the third bearing seat 16 is connected to the inner wall of the base frame 1;

[0030] During use, through the arrangement of the third bearing seat 16, the second linkage shaft 15 can be movably arranged;

[0032] When the embodiment of the present application is in use, first place the electric winch on the designated lifting platform at a high place of the building. Place the building materials to be lifted into the building basket, and then the lifting hook 21 hooks the building basket. Since the return spring 23 applies an elastic pressure to the abutting rod 22, one end of the abutting rod 22 always abuts against the inner wall of the abutting block 24, so that the lifting hook 21 can perform a locking hook on the building basket, reducing the phenomenon of the building basket falling during lifting and eliminating the safety hazards existing in the winch. Then, the motor 2 drives the first driving sprocket 13 to rotate. Since the diameter of the first driving sprocket 13 is smaller than the diameter of the first driven sprocket 14, the first driving sprocket 13 drives the first driven sprocket 14 to rotate slowly through the first chain 3, and the first driven sprocket 14 drives the second driving sprocket 17 to rotate synchronously through the second linkage shaft 15. Also, since the diameter of the second driving sprocket 17 is smaller than the diameter of the second driven sprocket 5, the second driving sprocket 17 drives the second driven sprocket 5 to rotate further slowly through the second chain 4. Then, the second driven sprocket 5 drives the drum 6 to rotate slowly through the first linkage shaft 9, so that the drum 6 slowly performs an electric winding on the rope 12, and thus can slowly and smoothly lift the building basket, reducing the phenomenon of shaking during the lifting of the building materials. Finally, a plurality of spring telescopic members 20 apply a downward elastic pressure to the brush plate 19, so that the brush plate 19 moves downward and the bristles at its bottom contact the outer wall of the rope 12. Then, the brush plate 19 can brush and clean the outer wall of the rope 12, and the brush plate 19 will not cause resistance to the winding and unwinding of the rope 12, thereby improving the cleanliness of the outer wall of the rope 12, and thus completing the use of the electric winch.
