Hydraulic-motor-driven pin-rail-type telescopic cage guide

Abstract

The invention discloses a hydraulic-motor-driven pin-rail-type telescopic cage guide which comprises an upper channel steel guide rail and a lower channel steel guide rail which are arranged at inlet and outlet of a horizontal layer of a vertical shaft well and fixed on a same axis. A movable guide rail is arranged below the upper channel steel guide rail, a retaining plate with a bar-type groove is arranged on the side of a notch of the upper channel steel guide rail, a driving device is arranged on the upper portion of the bar-type groove of the retaining plate and comprises a hydraulic motor, a coupler, a driving shaft and a driving gear, a pin rail meshed with the driving gear is arranged in the upper channel steel guide rail, a retaining plate limited on the lower portion of the bar-type groove is arranged on the inner side of the lower portion of the pin rail, a spindle is connected onto the pin rail on the lower portion of the retaining plate through a pin shaft, two wedges with protrusions are arranged on the spindle at an interval, and wedge seats wedged with the wedges with the protrusions are arranged in the movable guide rail respectively. The hydraulic-motor-driven pin-rail-type telescopic cage guide is simple in structure, strong in stability and adaptive to middle horizontal lengths of vertical shafts.

Description

technical field [0001] The invention relates to the field of mine lifting equipment, in particular to a hydraulic motor-driven pin-rail type 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 passing ...

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
