Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reels, in particular to a reel for a mine hoist. Background Art
[0002] Mine hoist refers to the main transportation equipment connecting the underground and the ground in mining projects. Mine hoist is installed on the ground and uses wire ropes to drive the lifting container along the shaft or ramp. It is used to lift coal, ore, gangue in vertical and inclined shafts, as well as to lift personnel, lower materials, tools and equipment, etc.
[0003] The existing mine hoist drum device has the main problem of being unable to extend the circular limiting plate during use, which results in the length between the circular limiting plate and the outer shell being unable to be extended. As a result, when carrying out transportation operations in deep mines, the number of wire rope circles that can be wound is reduced, which in turn affects subsequent work efficiency. Secondly, the existing mine hoist drum device also has the problem of not being able to quickly disassemble the reinforcement ring and the reinforcement ring for replacement or rust removal during use. As a result, the reinforcement ring and the reinforcement ring are very likely to rust after long-term use, which in turn affects the strength of the reinforcement ring and the reinforcement ring, causing the hardness of the device to be reduced. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a reel for a mine hoist, which has the advantages of length adjustment, quick replacement and rust removal, and solves the problems raised by the above-mentioned background technology.

[0009] As a preferred technical solution of the utility model: a groove is provided at the bottom of the clamping block 1, and the reinforcement ring and the reinforcement circle are clamped and connected to the inner wall of the groove.
[0010] As a preferred technical solution of the utility model: the first clamping block is located on the inner wall of the second clamping slot, and the first clamping block is slidably connected to the inner wall of the second clamping slot.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The drum for the mine hoist is used in conjunction with a threaded rod and three threaded holes. The threaded connection between the threaded hole and the threaded rod is utilized, and the threaded rod is then rotated counterclockwise to disengage the threaded rod from the inner wall of the threaded hole. At this time, the extension tube and the circular limiting plate can be removed, thereby facilitating the cleaning and maintenance of the inner wall of the through groove. At the same time, the three threaded holes are utilized to extend the circular limiting plate to three levels at both ends, so that more winding wires can be wound, thereby completing the transportation operation of deep-level mines.
[0013] 2. The drum for the mine hoist is used in conjunction with the slide plate and the clamping block 2. When the reinforcement ring and the reinforcement circle need to be replaced or removed for rust removal, the slide plate can be squeezed inward by both hands to use the deformation and contraction of the slide plate squeezing spring. At this time, the slide plate slides inward toward the inner wall of the slide groove, thereby causing the clamping block 2 to separate from the inner wall of the clamping groove 1. Then the clamping block 1 can be taken out of the inner wall of the clamping groove 2. At this time, the reinforcement ring and the reinforcement circle can be taken out through the inner wall of the through groove for replacement or rust removal. BRIEF DESCRIPTION OF THE DRAWINGS
