Tension monitoring device for mining endless rope winch

Abstract

The invention discloses a tension monitoring device for a mining endless rope winch. The device mainly comprises a tension measuring device and a display, wherein the tension measuring device comprises a tension wheel and an anti-jumper connector. Tension sensors are installed on the main and the auxiliary rope of the rope winch so as to monitor the tension change of the main rope and the auxiliary rope in real time. The display is connected to the tension sensors so as to visually monitor whether the tension of the main and the auxiliary rope is at a dangerous critical value. The tension sensors can set the tension safety range of the main and the auxiliary ropes, and when the tension exceeds the upper limit and the lower limit of the safety value, the tension measuring device sends an alarm and transmits the signal to the protection loop of an operation table so as to stop the winch working. Therefore, the problem of rope breakage and slipping caused by excessive tension and too small tension is effectively avoided, and the safety guarantee is improved.

Description

technical field [0001] The invention relates to a tension monitoring device, in particular to a tension monitoring device for a mine-used endless rope winch. Background technique [0002] The endless rope winch transportation is widely used in the coal mining industry due to its high transportation efficiency, replacing the traditional small winch transportation. The infinite rope winch adopts the friction traction method to generate the initial tension of the steel wire rope. During the transportation process, the wear or deformation of the steel wire rope will easily cause the initial tension of the steel wire rope to drop, causing the steel wire rope to slip on the drum. In the coal mine industry, there is still overloading during the transportation of the endless rope winch, and overloading will cause excessive tension of the twisted rope, which will cause a burden on the twisted rope and pose a safety hazard. However, excessive or too small tension in traditional winche...

Problems solved by technology

The infinite rope winch adopts the friction traction method to generate the initial tension of the steel wire rope. During the transportation process, the wear or deformation of the steel wire rope will easily cause the initial tension of the steel wire rope to drop, causing the steel wire rope to slip on the drum.

In the coal mine industry, there is still overloading during the transportation of the endless rope winch, and overloading will cause excessive tension of the twisted rope, which will cause a burden on the twisted rope and pose a safety hazard. However, excessive or too small tension in traditional winches mainly Judging by the winch driver's experience, the driver's overestimation or underestimation of the weight of the transported goods will have a great impact on the judgment result, resulting in consequences such as breakage of the winch rope, which will bring greater safety hazards to the operation
