Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an elevator rope breakage detection device. Background Technology

[0002] An elevator is a vertical lifting machine powered by an electric motor. Vertical elevators are equipped with box-shaped cabins and are used to carry people or goods in multi-story buildings. There are also stepped elevators, where steps are mounted on a continuous running track. During the operation of the elevator, ropes are used for tensioning. The repeated tensioning of the ropes will cause them to wear down.

[0003] However, existing elevator rope breakage detection devices have some problems in use. These devices typically detect rope breakage only after one rope has broken. When a rope breaks, it means the elevator will not be able to operate normally. If the rope breaks during operation, it may also cause physical injury to passengers. Utility Model Content

[0004] The purpose of this invention is to provide an elevator rope breakage detection device to solve the problems mentioned in the background art.

[0005] The present invention relates to an elevator rope breakage detection device, comprising a base plate, wherein vertical plates are fixedly connected to the top of the base plate near the left and right sides, and a rotating column is provided between the two vertical plates. The right end of the rotating column is inserted into the left side of the right vertical plate, and a motor is provided on the left side of the left vertical plate. A fixing seat is attached to the bottom of the motor, and the right side of the fixing seat is fixedly connected to the left side of the left vertical plate. A transmission rod is fixedly connected to the power output shaft of the motor, and the right end of the transmission rod passes through the left vertical plate and is fixedly connected to the left end of the rotating column.

[0006] In one embodiment, a steel wire rope is wound around the outer edge of the rotating column, and two arc-shaped plates are provided on the front side of the base plate near the right side. The two arc-shaped plates are arranged side by side and are together fitted around the outer edge of the steel wire rope.

[0007] In one embodiment, the top of the arc-shaped plate is provided with vertical holes near the front and rear sides, and a threaded rod is provided through each vertical hole. The top ends of two adjacent threaded rods are fixedly connected to an elastic rod, and a nut is threadedly connected to the outer edge of each threaded rod near the bottom.

[0008] In one embodiment, several monitors are fixedly connected to the side of the arc-shaped plate closest to the wire rope, and a pump is provided on the side of the arc-shaped plate away from the wire rope. Fixed rods are fixedly connected to both the front and rear sides of the pump, and the end of the fixed rod away from the pump is fixedly connected to the outer edge of the arc-shaped plate.

[0009] In one embodiment, the outer edge of the arc-shaped plate is provided with a connection hole near the top, and a horizontal tube is inserted through the connection hole. The end of the horizontal tube away from the wire rope is fixedly connected to the side of the adjacent pump, and a nozzle is fixedly connected to the end of the horizontal tube near the wire rope.

[0010] In one embodiment, each pump is fixedly connected to a vertical pipe at its bottom, and a vertical cylinder is fitted around the outer edge of each vertical pipe. A fixing plate is fixedly connected to the side of each vertical cylinder closest to the wire rope, and the side of the fixing plate furthest from the vertical cylinder is fixedly connected to the outer edge of an arc-shaped plate.

[0011] In one embodiment, an L-shaped rod is fixedly connected to the rear side of the arc-shaped plate near the top. A fixed plate is fixedly connected to the end of the L-shaped rod away from the arc-shaped plate. The inner cavity of the fixed plate is provided with four first threaded holes. Several second threaded holes are provided at the bottom of the base plate near the right side. Bolts are threaded into the first threaded holes. The top of the bolts is threaded into the adjacent second threaded holes.

[0012] The beneficial effects provided by this utility model are:

[0013] Through the coordinated operation of components such as the motor, curved plates, pump, and monitor, the motor drives the wire rope to stretch or wind up. Two curved plates are fitted over the surface of the wire rope, and the monitor on the curved plates monitors the surface of the wire rope. If the monitor detects wear on the surface of the wire rope, it sends an alarm to the controller, which then starts the pump. The pump absorbs white pigment from inside the vertical cylinder and sprays the white pigment onto the area near the wear on the wire rope surface, facilitating subsequent repair or replacement by maintenance personnel. The curved plates can also be disassembled for easy disassembly and repair. Attached Figure Description
