Abstract
The invention relates to a hydraulic support of a suspension roof timber capable of adjusting the direction, which is used for supporting an underground mining working face of a coal mine. A front telescopic block, a rear telescopic block and a push oil cylinder, which can enable a main beam and an auxiliary beam to realize horizontal and vertical dislocation are arranged between the main beam and the auxiliary beam, and the extension and the contraction of the front telescopic block and the rear telescopic block are controlled by a direction-adjusting oil cylinder, thereby realizing the function of transversely adjusting the support. The main beam, the auxiliary beam, the front telescopic block, the rear telescopic block, the push oil cylinder and upright posts constitute the hydraulic support of the suspension roof timber capable of adjusting the direction, which can be used independently, and a plurality of the hydraulic supports of the suspension roof timber capable of adjusting the direction can be further connected into a whole through front blocking blocks and rear blocking blocks to constitute a combined support of the suspension roof timber capable of adjusting the direction. The support has simple structure, convenience in combination, light weight, high strength, easiness in direction adjustment and strong stability, and can be used for mechanized mining, blasting mining and roof coal caving mining working faces.
Description
Technical field
The present invention relates to the support apparatus that a kind of colliery underground mining work plane uses, but be the tuning hydraulic prop for moving suspended top beam that is used for stope under the coal mine.
Background technology
The hydraulic prop for moving suspended top beam of present domestic use is the simple and easy hydraulic support of a kind of overarm step type, has that volume is little, in light weight, characteristics such as compliance is strong, can move certainly, low price, is widely adopted at some medium and small collieries.But be subjected to coal-face roof and floor planeness, movement of roof, and the influence of factor such as operating technology, in use, phenomenons such as that hydraulic prop for moving suspended top beam usually takes place is crooked, sideslip, because it is not provided with adjusting device, adjust very trouble, also the problem of falling the frame can appear sometimes.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, can adjust effectively that support is crooked, the tuning hydraulic prop for moving suspended top beam of sideslip but provide a kind of.
Purpose of the present invention can realize by following technical measures:
But a kind of tuning hydraulic prop for moving suspended top beam mainly is made up of girder, auxiliary girder, column, front stretching piece, the flexible piece in back, passing oil cylinder.
Be respectively equipped with a horizontal guide slot and a vertical T type gathering sill that distributes up and down in girder front part sides, both sides, rear portion; Be respectively equipped with a vertical T type gathering sill and a horizontal guide slot that distributes up and down in auxiliary girder front part sides, both sides, rear portion; The front stretching piece is made up of T connector I, block I, spacer pin and lifting ram, its block I left side is the horizontally-guided head, forming horizontal sliding with the girder horizontal guide slot is connected, rise and move the beam guide effect, T connector I shank portion is inserted into block I inside, T connector I right-hand member and auxiliary girder vertical T type gathering sill form the vertical slippage and connect branch, guarantee the changing of the relative positions mutually up and down of girder and auxiliary girder, jack is arranged in the block I cavity of resorption, two ends are hinged with block I and T connector I respectively, it is flexible in block I to handle T connector I, realizes laterally transferring frame; The flexible piece in back is compared with the front stretching piece, is provided with the ear seat in block II front side, and the placement direction of the flexible piece in back is opposite with the front stretching piece in the work; It is hinged with the auxiliary girder right plate to pass oil cylinder one end, and the other end and the back piece block II that stretches is hinged, is used to control move frame; Preceding contiguous block is made up of T connector II, block III, spacer pin with afterwards the contiguous block structure is identical, but is used for the connection between a plurality of independence tuning hydraulic prop for moving suspended top beam, but constitutes the suspended back timber sectional shelf-unit of tuning.
The invention has the beneficial effects as follows: by the combination of front stretching piece, the flexible piece in back and girder, auxiliary girder and passing oil cylinder, constituted novel thrust gear, but thereby form a kind of independent used tuning hydraulic prop for moving suspended top beam, but two and above tuning hydraulic prop for moving suspended top beam can be linked to be an integral body by preceding contiguous block, back contiguous block again, but constitute the suspended back timber sectional shelf-unit of tuning.That this support has is simple in structure, combined and instant, in light weight, intensity is high, easy tuning, stability are strong, can be used for that machine is adopted, big gun is adopted, the caving coal mining work plane.
