An ultra-deep mine hoist multi-rope cooperative control system test bench

Abstract

A multi-rope cooperative control system testbed for an ultradeep mine hoist, which relate to multi-rope cooperative control system testbeds for hoists. A hydraulic motor (1) is connected to a roller (2) by means of a coupling (14). The roller (2) is provided with to a steel wire rope (3). The steel wire rope (3) is connected to a cage (13). A tension sensor (11) is placed on the steel wire rope (3) to detect tensile force of the steel wire rope and feed back a signal. A servo hydraulic cylinder (6) is fixed on a hinge (9), and the upper end is connected to a head sheave bracket (9). A head sheave (8) is connected to the head sheave bracket (9), and the head sheave bracket (9) is fixed on a linear guide rail (7). The hinge (9) and the linear guide rail (7) are connected to a steel structural bracket (4). The servo hydraulic cylinder (6) drives the head sheave (8) to move up and down by means of the head sheave bracket (9). The tension sensor (11) is placed on the steel wire rope (3) to detect the tensile force of the steel wire rope (3). A pressure sensor (10) is placed on the head sheave bracket (9) to detect a pressure applied to the head sheave (8). A spiral instrument (12) is fixed above the cage (13) to detect whether the cage (13) is horizontal. The cage (13) is located in the steel structural bracket (4). The hydraulic motor (1) is mounted on a motor base (15). In the testbed, the cage is perpendicularly hoisted by using a mode of the drag of the hydraulic motor, thereby making the operations simple, and helping to carry out maintenance.

Description

technical field [0001] The invention relates to a test bed for a multi-rope coordinated control system of a hoist, in particular to a test bed for a multi-rope coordinated control system for an ultra-deep mine hoist. Background technique [0002] At present, as my country takes the development of deep resources as an important development strategy, large-scale hoisting equipment for ultra-deep mines has become the key equipment for realizing the development of deep resources. However, my country's research on hoisting equipment for ultra-deep mines has just started, which restricts the implementation of my country's deep resource development and utilization strategy. Moreover, due to the complex actual working conditions of ultra-deep mines and the special mining environment, it is difficult to conduct field tests on lifting equipment. Therefore, in order to verify the working performance of the ultra-deep mine hoisting equipment and realize the detection level of the ultra...
