Hydraulic motor driven connecting rod hinge type telescopic shaft guide

Abstract

The invention discloses a hydraulic motor driven connecting rod hinge type telescopic shaft guide which comprises an upper channel steel guide rail and a lower channel steel guide rail which are respectively fixed on the same axis and above and below the middle horizontal section; the middle shaft side of the upper channel steel guide rail is provided with a hydraulic motor, a coupler, a driving shaft and a driving gear; the hydraulic motor can drive the driving gear to be meshed with a pin rail pin shaft in the upper guide rail, so that the pin rail slides up and down in the upper guide rail; a baffle is fixedly arranged on the inner side of the lower end of the pin rail; the pin rail on the lower part of the baffle is hinged with a sliding shaft; the sliding shaft is arranged in a chute in the upper end of a main shaft in a penetrating manner and can slide along with the chute; multiple stoppers are fixed in the middle of the main shaft; two sides of the stoppers are hinged with a first connecting rod and a second connecting rod; and the first connecting rod and the second connecting rod are respectively hinged with fixing seats on a first movable guide rail and a second movable guide rail. The limitation of the opening length of the middle horizontal shaft guide on the length of a hydraulic cylinder of driving equipment is overcome, and the retraction of the large-travel even extra-large-travel shaft guide can be realized; the operating efficiency of a coal mine vertical shaft cage is greatly improved; and moreover, the hydraulic motor driven connecting rod hinge type telescopic shaft guide is simple in telescopic structure and high in stability.

Description

technical field [0001] The invention relates to the field of mine hoisting equipment, in particular to a hydraulic motor-driven connecting rod hinged telescopic tank road suitable for cage lifting. Background technique [0002] At present, cage lifting transportation is the main way of shaft personnel transportation. Shafts generally have multiple horizontal layers. When the cage reaches the horizontal layer, mine car personnel can enter and exit the cage, and take the cage to reach different horizontal layers. When mining vehicles and personnel need to enter and exit the cage, the cage tank must be disconnected to allow the mining vehicles and personnel to pass through smoothly. At this time, there are fractures in the tanks of each horizontal layer. When the cage runs through the horizontal layer due to the lack of tank guides , can not run at full speed, otherwise it is easy to cause accidents; due to the existence of tank road fractures, the cage must slow down when pa...

AI Technical Summary

Problems solved by technology

Although the patent No. CN10151314A discloses a telescopic tank for raising the middle level of the mine shaft, although it can solve the problem of the fracture of the tank, the telescopic structure is complicated and the stability is poor. The expansion and contraction is driven by a hydraulic cylinder. The opening of the tank is very long, and the telescopic length of the hydraulic cylinder is limited, making it difficult to popularize and use. Therefore, it is necessary to propose a new type of telescopic tank to overcome the bottleneck of the telescopic length of the hydraulic cylinder
