Sensing device for carrying out real-time monitoring on load bearing of single-rope winding hoisting system

Abstract

The invention discloses a sensing device for carrying out real-time monitoring on load bearing of a single-rope winding hoisting system, belonging to mining equipment.The device comprises a rack, an upper pull rod, a detection fuel tank, an upper bearing block, a lower bearing block, a pressure transmitter and a wireless transmitting module.The rack consists of two connected lateral plates, the upper bearing block is arranged at the upper ends of the two lateral plates, the lower ends of the lateral plates are connected with a lower connector which is connected with a container.The upper pullrod is neither connected with the lateral plates nor connected with the upper bearing block, the upper pull rod is connected with the upper connector, and the upper connector is connected with a hoisting steel wire rope. The detection fuel tank is connected with the upper bearing block, a piston rod is adjacent to the lower bearing block, the lower bearing block is plugged in long holes of the lateral plates in a sliding-fit manner, the pressure transmitter is arranged at the port of the detection fuel tank and connected with the wireless transmitting module. When loading is carried out on the container, the signals detected by the pressure transmitter are loaded weight signals; in the process of normal operation of the container, the signals detected by the pressure transmitter are loading signals from a steel wire rope terminal.

Description

technical field [0001] The invention relates to a mine equipment, in particular to a steel wire rope tension sensor device used in a single-rope winding hoisting system carrying a real-time monitoring system. Background technique [0002] Article 382 of the "Coal Mine Safety Regulations" stipulates that "the maximum load capacity and maximum load difference of the hoisting device shall be announced at the wellhead, and overloading and operation with overloading weight difference are strictly prohibited." At present, only "qualitative" management can be relied on, and "quantitative "Intrinsically safe management of overload lockouts. For example, how much material is loaded in the hoisting system of the auxiliary shaft of the mine, the unit weight and counterweight of the heavy lifting, etc., it is difficult to accurately control the tonnage. Although there is a fixed-weight loading system for the hoisting system of the main shaft, the sticking of the skip is problematic. , ...
