Description

Technical Field

[0001] The utility model relates to the field of compensating chains, in particular to a compensating chain with high stability. Background Technique

[0002] The compensating chain is generally also known as the elevator balance chain and is an important part of the elevator system. It is mainly used to balance the weight difference between the elevator car and the counterweight. The compensating chain balances the weight difference between the car and the counterweight through its own stretching or contraction, so as to ensure the smooth operation of the elevator.

[0003] However, there are still some deficiencies in the current compensating chain. For example, the disassembly and assembly steps of the existing compensating chain are relatively cumbersome, resulting in a long time for the staff to overhaul and replace the compensating chain, which brings a certain interference to the overhaul and replacement efficiency of the staff, and thus there are certain use defects.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structural deficiencies and provides a compensating chain with high stability. Content of the Utility Model

[0005] The purpose of the utility model is to provide a compensating chain with high stability to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a compensating chain with high stability, including a suspension sleeve and a connection component. A round head screw is rotatably connected to the top of the suspension sleeve, and a thin nut is threadedly connected to the outer surface of the round head screw. A first flat washer is attached to the top of the thin nut, and a first lock nut is attached to the top of the first flat washer. At the same time, the inside of the first lock nut is threadedly connected to the side of the round head screw. The connection component is movably installed inside the suspension sleeve, and a connection steel wire rope is movably installed inside the suspension sleeve. A locking component is attached to the outer surface of the connection steel wire rope, and a positioning block is fixedly connected to the end of the connection steel wire rope.

[0007] Further, the lower end of the round head screw is arranged inside the suspension sleeve, and the end of the round head screw forms a rotating structure with the suspension sleeve through a single-direction thrust ball bearing.

[0008] Further, the connection component includes a fixing bolt, a hexagon nut, a spring washer and a second flat washer. The outer surface of the end of the fixing bolt is threadedly connected to the hexagon nut. A spring washer is attached to the inner side of the hexagon nut, and a second flat washer is attached to the inner side of the spring washer. At the same time, the outer surface of the fixing bolt penetrates and is movably connected inside the suspension sleeve.

[0009] Further, the outer side of the second flat washer is in fitting connection with the inner side of the spring washer, and the inner side of the second flat washer is in fitting connection with the outer surface of the hanging sleeve, and the second flat washer is sleeved on the outer surface of the fixing bolt.

[0010] Further, the locking assembly includes a wire rope clip, a through hole, a U-shaped locking rod, a threaded rod and a second locking nut. Through holes are symmetrically formed in the front and back of the inside of the wire rope clip, and a U-shaped locking rod is movably connected inside the through hole. A threaded rod is fixedly connected to the end of the U-shaped locking rod, and a second locking nut is threadedly connected to the outer surface of the threaded rod.

[0011] Further, the external dimension of the U-shaped locking rod completely matches the internal dimension of the through hole, and the U-shaped locking rod is movably connected to the inside of the wire rope clip through the through hole.

[0012] Further, the inside of the second locking nut is threadedly connected to the outer surface of the threaded rod, and the inner side of the second locking nut is in fitting connection with the outer side of the wire rope clip.

[0013] Further, the top of the positioning block is fixedly connected to the end of the connecting wire rope, and the inner surface of the positioning block is in snap connection with the outer surface of the U-shaped locking rod.

[0014] The utility model provides a compensation chain with high stability, having the following beneficial effects:

[0015] 1. Through the through holes provided in the utility model, the U-shaped locking rod can easily pass through the inside of the wire rope clip. At this time, the connection wire rope is clamped through the inner sides of the wire rope clip and the U-shaped locking rod. Then, through the mutual cooperation of the threaded rod and the second locking nut, when the staff rotates the second locking nut to move along the outer surface of the threaded rod, the U-shaped locking rod can be driven to move towards the inside of the wire rope clip, so as to further complete the locking work of the connection wire rope, thereby ensuring that the connection wire rope will not loosen when bearing the chain. At the same time, when the staff rotates the second locking nut outwards, the connection wire rope can also be quickly unlocked, thus providing convenience for the staff to disassemble and assemble the chain, and further avoiding the situation that the staff needs to spend a long time when overhauling and replacing the compensation chain, which interferes with the overhaul and replacement efficiency of the staff. At the same time, the setting of the positioning block can effectively prevent the connection wire rope from directly disengaging from the U-shaped locking rod when it loosens.
