Title:
MULTI-ROPE COOPERATIVE CONTROL SYSTEM TESTBED OF ULTRADEEP MINE HOIST
Document Type and Number:
WIPO Patent Application WO/2017/101688
Kind Code:
A1
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.
