Abstract
The invention relates to a flexible support for supporting the underground coal mine mining working face. A plurality of narrow top beams are distributed above a base in parallel, each top beam is supported by a front vertical post and a back vertical post, and all top beams are connected with each other by using connecting blocks among the beams so that certain mutual deflection and dislocation among the top beams are ensured; telescopic beams are arranged in top beams and controlled by large-stroke telescopic lifting jacks, and when the flexible support works, the telescopic beams support a coal wall so that the coal wall can resist a certain horizontal external load; elastic guide rods are arranged behind the back vertical posts, the upper ends of the elastic guide rods are articulated with the top beams by pin shafts or crossed joints, and the lower ends are inserted to guide sleeves with a guide line being perpendicular to the bottom of the base, thereby the elastic guide rods are used for guiding lifting, keeping the shape of the support, blocking waste rock and horizontally yielding; and a waste rock blocking plate is installed at the tails of the top beams and used for protecting the elastic guide rods and preventing the waste rock from entering. The tail beams of the support can be removed so that the support has the advantages of light weight, high strength, rapid movement, good stability, strong adaptability, convenient shipment and the like, and is especially suitable for supporting the coal-mining working faces with uneven top plates and fluffy bottom plates.
Description
Technical field
The present invention relates to the support apparatus that a kind of colliery underground mining work plane uses, be specially adapted to a kind of flexible support of middle and small scale coal mine complex geological condition.
Background technology
The coal-face support apparatus of present domestic use mainly contains integral supports such as four connection-rod support, single wobbling pole support, and two kinds of citation forms of simple rack such as sliding type cap for supporting mine roof, suspended bar timber.Characteristics such as integral support has that intensity height, weight are big, reliable operation, advancing velocity are fast, globality and good stability, but for numerous middle and small scale coal mine, owing to be subjected to the influence of factors such as geological conditions complexity and insufficient funds, limited promoting the use of of they.And simple and easy automatic shifting stands such as slipping bar compos ite support, suspended bar timber, have that volume is little, in light weight, compliance is strong, can realize the characteristics that oneself moves, but in use, that these supports occur easily is crooked, fall frame, buried column, insert problems such as the end, particularly work as a support frame takes place, the adjacent frame of very easier initiation falls frame, forms chain reaction, and ordinary production and personal security are constituted a serious threat.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, a kind of novel flexible support between integral support and simple rack is provided, its rearmounted elasticity guide rod device has guiding, retainer type and retaining cash function concurrently, and can the realization level allows pressure; A plurality of back timber structures can better adapt to top board and change; Unsplit bedplate can be guaranteed support self stability and fast-moving bracket.
Purpose of the present invention can realize by following technical measures:
A kind of flexible support, mainly form by contiguous block, elasticity guide rod between a base, a plurality of back timber, column, beam, also column distribution a plurality of narrow type back timbers above base, connect by contiguous block between beam between each back timber, each back timber is connected with base with bearing pin with ball pivot by front column, rear column, flexible jack one end of big stroke and extensible canopy are hinged, and the other end and back timber are hinged, pass oil cylinder and push rod and are arranged between the left and right pillar; The elasticity guide rod is arranged in the rear portion of rear column, and the upper end and the back timber of elasticity guide rod are hinged, and insert in the fairlead of guide passage line perpendicular to base end face the lower end, and waste rock board is connected the afterbody of back timber.
Purpose of the present invention also can realize by following technical measures:
Base of the present invention is a unsplit bedplate, is horizontally arranged with the fairlead of a plurality of guide passage lines perpendicular to base end face at its rear portion.
Elasticity guide rod of the present invention is formed by stacking by steel spring plate, and its upper end is hinged with back timber with bearing pin or cross joint.
Back timber of the present invention is narrow type back timber, two, three, four, five, six back timbers of back timber for being provided with, and each back timber sidepiece is equipped with one or former and later two verticals T type gathering sill.
Waste rock board of the present invention is mounted on the back timber afterbody by bearing pin.
The invention has the beneficial effects as follows:
Adopt linkage, rearmounted resilient guiding device between unsplit bedplate, split back timber structure and beam, constituted a kind of flexible support.This support had both had integral support good integrity, high, the fast characteristics of advancing velocity of stability, have again that the simple rack volume is little, in light weight, compliance is strong, be convenient to adorn, tear open, operate the characteristics of industry, can be used for that machine is adopted, blast mining face, be particularly useful for top board injustice, stope that base plate is soft, have high cost performance, can promote the use of at medium and small colliery.
