Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to an adjustable roller frame for a mine hoist wire rope. Background Art

[0002] Some hoists are limited by space during installation. Multiple hoists can only be arranged on the same side, resulting in a 79-meter-long rope extension for a 5-meter hoist. To solve the problem of large wire rope swing during hoist operation, wire rope rollers are installed between the derrick and the hoist room to support the wire rope and solve the swing and jump problems of the wire rope during operation.

[0003] The existing wire rope bracket directly installs the roller on the bracket steel beam, and the wire rope and the roller are in hard contact. The following problems exist during operation: Since the roller is directly installed on the steel beam, it is necessary to adjust the distance between the roller and the wire rope by adding a shim, and the installation and debugging of the roller is difficult; since the roller is fixedly installed and cannot be adjusted at any time, when the bucket is in the upper half of the shaft, the wire rope has a large verticality, and the roller is in an excessive rope resistance state; when the bucket is in the lower half of the shaft, the wire rope has a small verticality, and the roller is separated from the wire rope, and it cannot play a supporting role; the sliding bearing used in the original roller has a large rotation resistance, and the roller speed cannot keep up with the wire rope speed, which easily causes the roller to wear. Because the wire rope bracket cannot support the wire rope well, the wire rope has a large swing and jumps, causing the wire rope to bite the rope or even jump out of the rope groove and the sheave, and it is impossible to speed up at full speed, and it can only maintain low speed operation, with high system risks and low lifting efficiency.
