Description

Technical Field

[0001] The utility model relates to a multifunctional auxiliary mechanism for coal mine conveying, belonging to the technical field of auxiliary equipment for coal mine mining. Background Art

[0002] During the installation of a high-strength belt, an installation frame is formed by two front and rear H-frames and two left and right longitudinal beams to fix the idlers and support the belt. The inner width of a certain H-frame is 1230 mm, the belt width is 1000 mm, and there is a distance of 115 mm between both sides of the belt and the H-frame. If the conventional lower idler for preventing belt deviation and the lower idler frame are installed on the longitudinal beam, since the total width of the lower idler and the lower idler frame is 132 mm, which is 17 mm larger than the distance between both sides of the belt and the H-frame (115 mm), the belt and the lower idler will be in a state of mutual wear for a long time, resulting in easy damage to the belt and the lower idler, frequent maintenance is required, the cost investment is increased, and the production efficiency is reduced.

[0004] The technical solution adopted by the utility model is: a multifunctional auxiliary mechanism for coal mine conveying, including a longitudinal beam. A section in the middle of the longitudinal beam horizontally moves outward a certain distance to form a second longitudinal beam, and the rest of the longitudinal beam is the first longitudinal beam. The second longitudinal beam is fixed to the first longitudinal beam, and a lower idler for preventing belt deviation with its axis arranged vertically is installed on the second longitudinal beam.

[0005] Preferably, the length of the second longitudinal beam is 180 - 220 mm.

[0006] Preferably, the horizontal moving distance of the second longitudinal beam is 100 - 110 mm.

[0010] Preferably, it further includes an adjusting mechanism. The adjusting mechanism includes a strip-shaped sliding groove opened at the upper end of the lower idler bracket. The strip-shaped sliding groove is a through groove, which is arranged horizontally and perpendicular to the second longitudinal beam. The mounting shaft of the lower idler vertically penetrates the strip-shaped sliding groove and can slide along the sliding groove. A fixing ear is fixed at the upper end of the mounting shaft of the lower idler, and the fixing ear is limited at the upper end of the lower idler bracket by bolts. There is also another adjusting mechanism, and the other adjusting mechanism is arranged at the lower end of the lower idler bracket.

[0013] 1. Compared with the prior art, the present utility model has the following beneficial effects:

[0014] (1) It can prevent the lower belt of the high-strength belt from running off track, and at the same time prevent the high-strength belt from rubbing against the longitudinal beam and the H-frame.

[0015] (2) The longitudinal beam of the reformed high-strength belt is also used as the mounting bracket of the lower idler bracket, which solves the problem of long-term mutual wear between the lower idler and the high-strength belt caused by conventional installation.

[0016] (3) By reforming the existing longitudinal beam, the input of materials and processing costs is reduced.

[0017] (4) The length of the longitudinal beam remains unchanged, still meeting the use requirements, and the idler bracket and idler are convenient to install.

[0018] (4) The service life of the lower idler is twice that before the reform. 10 lower idlers can be saved in one year; the belt wear cost can be saved about 20,000 yuan in one year. The total annual efficiency can be created: 2 + 0.1 = 21,000 yuan / year.
