Problems solved by technology

The present invention is equipped with a sensor at the top and the bottom of the construction elevator, which is used to detect the metal object directly in front of it, so as to detect whether the elevator is still within the range of the guide rail, if one of the sensors does not detect the guide rail, then The power supply of the elevator is cut off by the control system to avoid the derailment of the elevator. Although this invention can prevent the derailment of the elevator, since no signal isolation device is installed on the sensor in this invention, it is easily interfered by external signals, resulting in poor stability and safety. , low reliability

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment

[0014] see figure 1 As shown, a construction hoist anti-derailment device includes two annular electromagnetic locks 10 and two metal fixing rods 12 vertically and spaced apart, wherein the electromagnetic lock 10 is set on the fixing rods 12, and the electromagnetic lock 10 is in the open state Can move up and down along the fixed rod 12, the electromagnetic lock 10 is fixedly connected with the cage 14 of the elevator through the steel wire rope, and the electromagnetic lock 10 is also electrically connected with the control device of the elevator. When the cage moves to the top of the frame, the control device sends a control signal to the electromagnetic lock 10 to energize it to reach the locked state. The electromagnetic lock 10 can be firmly fixed on the fixing rod in the locked state, thereby preventing the elevator from derailin...

Abstract

The invention discloses a derail-resisting device for a construction lifting machine, which is characterized by comprising an electromagnetic lock and a vertically arranged fixing rod. The electromagnetic lock is installed on the fixing rod and fixedly connected with a lifting cage of the lifting machine through a steel wire rope, and the electromagnetic lock is further electrically connected with a control device of the lifting machine. The derail-resisting device for the construction lifting machine is good in stability, safe and high in reliability.

Description

technical field [0001] The invention relates to a construction elevator, in particular to an anti-derailing device for a construction elevator. Background technique [0002] The construction hoist is a kind of construction machine that uses a cage to carry people and objects, and is transported vertically along the guide rail frame. It is mainly used for the construction and maintenance of high-rise buildings. The power for the cage to run up and down comes from the drive device. When the construction hoist is used, installed and disassembled, there is a danger that the cage or the driving device will move out of the guide rail (to the roof). At present, the construction elevators in normal use are equipped with upper and lower limit limit rails, which can effectively prevent the cage from driving out of the guide rails. The limit touch iron needs to be removed first, otherwise the construction hoist cannot be disassembled by itself. In this case, the accident of the cag...
