Detection device for steel wire rope tension of friction type hoister

Abstract

The invention discloses a detection device for steel wire rope tension of a friction type hoister. Two full hydraulic automatic balancing devices are respectively installed on two cages, the two full hydraulic automatic balancing devices are respectively connected with both ends of a steel wire rope, two steel wire rope tension sending parts are respectively installed on the two cages, a steel wire rope tension receiving part is installed in a hoister room, a base station is connected with a leaky cable, the leaky cable is connected with a terminal box, the head of the leaky cable is positioned underground, and a processed wireless signal is transmitted to the steel wire rope tension receiving part by the base station. A data processing part of the detection device is composed of a power supply, a human-computer interface, an in-place switch, a signal switch, a control switch and a programmable logic controller. The data processing part is used for completing processing on steel wire rope tension data of the friction type hoister and completing the detection on the in-place position and operating states and the power-off control of the friction type hoister. The detection device is used for detecting the steel wire rope in a coal mine.

Description

technical field [0001] The invention relates to a steel wire rope tension detection device in the field of mine electromechanical-hydraulic integrated control, in particular to a friction hoist steel wire rope tension detection device. Background technique [0002] Large and medium-sized coal mines at home and abroad are designed with a main and auxiliary shaft hoisting system. The auxiliary shaft hoisting system is used to lift various materials, tools, equipment, gangue and operators used in the coal mine underground. The main shaft is used to lift the coal mined from the mine. mineral. The friction hoist has been widely used in mine hoisting because of its advantages such as small friction drum and wire rope diameter, higher safety factor, and compact whole set of equipment. The friction hoist is a bit-type mechanical equipment. A plurality of steel wire ropes are covered on the friction drum. The two ends of the wire rope are connected to the lifting container, and the ...

Problems solved by technology

[0015] device, because the hoisting container of the friction hoist is a mobile device, only the wireless detection method can be used, but because the metal derrick is installed in the shaft, many wireless detection methods are difficult to be effective, so there is no high reliability, mature The product
