Detailed Description

As shown in fig. 1, when the power unit 5 rotates clockwise, the driving sprocket 1 is driven to rotate clockwise, the lifting link chain 2 also moves clockwise, and the link chain hitching member 3 is fastened to the link chain of the lifting link chain 2, and thus moves downward with the link chain, and vice versa.

As shown in fig. 2, the lifting link chain 2 may also be a composite structure formed by connecting a link chain and a secondary chain, so as to achieve the effects of reducing the overall weight and saving the cost. The auxiliary chain can be a thin ring chain or a steel wire rope.

As shown in fig. 3, the tension pulley 4 may also be a tension pulley set composed of two or more pulleys arranged in parallel in the horizontal direction, so that the chain 2 is arranged in a non-parallel manner, such as a triangle with a wide top and a narrow bottom, thereby preventing the chain link 3 and the link parts thereof from contacting the chain, and further causing friction and collision.

As shown in fig. 4, in the case where the entire hoist link chain is in the form of a link chain, the link chain links 3 may be coupled and fixed to the link chain and the wall attachment at desired positions on one side or both sides.

Example one

As shown in fig. 4, the power device 5 and the tension roller 4 are fixed on the scaffold body 8, the hoisting chain is tensioned by the tension roller 4, the chain link 3 is connected with the wall-attached device 7, and the wall-attached device is connected and fixed with the building 9. The power device 5 rotates clockwise, the distance between the loop chain hanging piece 3 and the power device 5 is shortened, the loop chain hanging piece 3 is fixed with the building through the wall attaching device, the power device 5 is fixed with the scaffold body, therefore, the scaffold body moves upwards relative to the building, after the scaffold body moves to a required position and is fixedly connected with the building in other modes, the loop chain hanging piece 3 is disconnected with the wall attaching device, the loop chain hanging piece 3 is detached from the loop chain and then moves to the position connected with the wall attaching device next time, and is fixedly connected with the wall attaching device and the loop chain to prepare for next operation of the scaffold body.

When the scaffold body descends, the power device rotates anticlockwise, and other operation modes are basically the same.

Example two

As shown in fig. 5, the power device 5 is fixed on the wall-attached device 7, the wall-attached device is connected with the building 9, the loop chain hanging piece 3 is fixed with the scaffold body 8 which needs to be lifted, the power device 5 rotates anticlockwise, the distance between the loop chain hanging piece 3 and the power device 5 is shortened, the scaffold body 8 moves upwards relative to the building, after the scaffold body moves to a required position, the scaffold body is connected and fixed with the building in other modes, the connection between the loop chain hanging piece 3 and the scaffold body is released, the loop chain hanging piece 3 is removed from the loop chain and then moves to the position connected with the scaffold body next time, and is connected and fixed with the loop chain and the scaffold body to prepare for next operation of the scaffold body.

When the scaffold body descends, the power device rotates clockwise, and other operation modes are basically the same.

As shown in fig. 6-8, the link chain coupling member is formed by attaching two pressing plates 12 and fastening them by bolts 10, the inner sides of the pressing plates and the link chain are tightly fixed and coupled by concave-convex fit, and the coupling and fixing between the inner sides of the pressing plates and the link chain can be released by loosening the bolts. In this embodiment, the coupling position of the loop chain coupling member and the wall attachment device is a coupling method of the U-shaped long groove 11, and of course, coupling methods such as a hook, a circular hole, a bolt, and the like may be used.

As shown in fig. 9, when the position of the wall-attached device is shifted, the number of tensioning rollers can be increased to form a tensioning roller set to adjust the position of the chain of one side of the chain in a linear state through the wall-attached device.
