Wire rope guide rail tensioning device for mining elevator

Abstract

The invention discloses a wire rope guide rail tensioning device for a mining elevator, which comprises an industrial personal computer, a signal acquirer, wire rope guide rails, counterweight devices and a rope regulation device. Reversely symmetrically arranged wire rope fixing devices are arranged at the upper and lower ends of the wire rope guide rails. Upper wire rope fixing devices are fixed on upper carrier bars. Pressure sensors connected with the signal acquirer are arranged between the upper wire rope fixing devices and the upper carrier bars. Tensioning devices fixed on lower carrier bars are connected to lower wire rope fixing devices. The wire rope fixing devices arranged at the upper and lower ends of wire ropes can safely and reliably fix the wire rope guide rails, and tensioning forces are applied to the wire ropes by the tensioning devices and the counterweight devices arranged on a lower part so as to realize the longitudinal guide and transverse swing restraint of acage in a lifting running process. The wire rope guide rail tensioning device has a compact structure and reliable performance, is easy to machine and simple in installation and maintenance, can monitor the tensioning forces of the guide rails in real time and give an alarm online according to the monitored tensioning forces, and improves the taking safety and reliability of the cage.

Description

technical field [0001] The invention relates to a mine-used elevator wire rope guide rail tensioning device, which is especially suitable for an elevator guide rail system using steel wire ropes as guide rails. Background technique [0002] At present, the elevator car is mainly guided by guide rails during the up and down transportation process, and the guided guide rails mainly adopt rigid guide rails installed on the hoistway and supported by brackets. However, under harsh working conditions such as underground engineering, especially when the shaft wall is under huge pressure and the shaft is deformed, it is easy to cause the mine elevator car to run unstable or even get stuck in the shaft, which brings great harm to the safe operation of the elevator. hidden dangers.

Problems solved by technology

However, under harsh working conditions such as underground engineering, especially when the shaft wall is under huge pressure and the shaft is deformed, it is easy to cause the mine elevator car to run unstable or even get stuck in the shaft, which brings great harm to the safe operation of the elevator. Hidden dangers

In the existing mine shaft, in order to solve the time-consuming, laborious and unsafe factors in the installation of general rigid guide rails, a steel wire rope tank system with heavy hammer tension is adopted. The heavier the goods, the greater the mass of the tensioning hammer and the larger the space it occupies. Therefore, it is necessary to dig a deeper well bottom water nest. If coal and other debris are scattered into the water nest, the well will When the bottom water pocket is filled up, the tension force of the weight decreases, resulting in serious lateral deflection of the lifting container. At the same time, when adjusting the tension force, the work efficiency is low, the labor intensity is high, and the precise weight of the weight is difficult to adjust

At present, mine elevators use wire rope as the guide rail of the car, and there is no convenient, stable, and reliable wire rope guide rail tensioning device to adapt to it.

Therefore, by designing a steel wire rope guide rail tensioning device suitable for mine elevators, the tension adjustment has stable and reliable tension and can be monitored in real time. Rigid guide rail installation is time-consuming, labor-intensive, and has potential safety hazards
