Abstract
The utility model relates to a front-arranged single oscillating bar type end hydraulic support, in particular to a front-arranged single oscillating bar type end hydraulic support device for supporting a coal-mining working surface end. A column pit, extensible columns and a hydraulic support are arranged on a base, the extensible columns are arranged in the column pit, and a hinge joint seat and an oscillating bar are arranged on the hydraulic support. One end of the oscillating bar is arranged in the hinge joint seat, the hinge joint seat is arranged at one end of an inclined top beam, and the other end of the oscillating bar is arranged in the hinge joint seat at one end of the inclined top beam. Four extensible columns abut against the inclined top beam, an inclined beam and a top beam form the inclined top beam, single-lug hinge joint lug seats are welded on two sides of the front end of the base, and hinge joint clamping chain seats are connected with pulling-moving jacks on two sides of a transferring machine body through chains so as to achieve self movement. The front-arranged single oscillating bar type end hydraulic support has the advantages that the structure is simple, operation is convenient, a single oscillating bar type structure is adopted so that occupied space is small, a chain pulling-moving self movement method is adopted so that work efficiency is high, the oscillating bar replaces the columns so that the cost is low, and the end hydraulic support is widely used for supporting the coal-mining working surface end.
Description
Technical field
The utility model relates to a kind of preposition single swing link type end hydraulic support, especially for the coal-face end support with preposition single swing link type end hydraulic support equipment.
Background technology
At present, install close standing props behind the elevating conveyor tail and be commonly called as the pillar of closing the door, ten individual props of general maximum uses whenever advance head and just need draw for 1.2 meters and move elevating conveyor No. one time, install the pillar of closing the door again by manual work then, return and withdraw from original pillar of closing the door.Artificial prop up back, not only labour intensity is big, use duration, at every turn all need be more than one hour, inefficiency, and return remove during the easy inbreak of top board, the individual prop that time goes out need transport from elevating conveyor, is whole comprehensive one of dangerous point in the work of adopting.Simultaneously, the supporting intensity of individual prop is low, and supporting effect is poor, has a strong impact on production, even the phenomenon that individual prop can't return out occurs.The crossheading end support of work plane has become the restriction fully-mechanized mining working to advance the bottleneck that improves with output fast.
Summary of the invention
The purpose of the utility model provides a kind of preposition single swing link type end hydraulic support, and it is to adopt the mono-pendulum type structure; The automatic moving type end hydraulic support; Four telescopic posts on the base, the back timber that is arranged on telescopic post top integrative-structure through the column nest is connected with cant beam, in base front end edge support width direction the fork hinged seat is set vertically upward; Fork hinged seat upper end is hinged fork one end respectively, and the fork other end is hinged with the cant beam lower end respectively; The hinged ear seat of welding monaural in base front end both sides, hinged chain jamming seat move jack through chain and drawing of elevating conveyor body both sides and link to each other realization from the purpose of moving.
The preposition single swing link type end hydraulic support of the utility model takes following technical scheme to realize; It is to be made up of base, telescopic post, column nest, oblique back timber, hinged seat, fork, the hinged ear seat of monaural, hinged chain jamming seat, chain and jack and hydraulic support, and column nest and telescopic post and hydraulic support are set on the base, device telescopic post in the column nest; Hinged seat and fork are set on the hydraulic support; Device fork one end in the hinged seat, tiltedly back timber one end is provided with hinged seat, and fork other end device is in the hinged seat of oblique back timber one end; Withstand oblique back timber by four telescopic posts; Cant beam and back timber constitute oblique back timber, and the hinged ear seat of base front end both sides welding monaural, hinged chain jamming seat move jack through chain and drawing of elevating conveyor body both sides and link to each other realization from moving.
The effect of the preposition single swing link type end hydraulic support of the utility model is simple in structure, and is easy to operate, adopts the mono-pendulum type structure; It is little to take up room; The automatic moving type method adopts chain to draw and moves, and high efficiency utilizes fork to omit column; Cost is low, is widely used in the equipment that the supporting of coal-face lower end is used.
