Abstract

Disclosed is a direction-adjustable suspension top beam hydraulic support which is used for timbering coal mine underground mining working faces. A front retractable block, a rear retractable block and a pushing cylinder are mounted between a main beam and an auxiliary beam so as to guarantee horizontal and vertical staggering of the main beam and the auxiliary beam, retraction of the front retractable block and the rear retractable block is controlled by a direction-adjusting cylinder, so that a transverse support adjustment function can be realized. The main beam, the auxiliary beam, the front retractable block, the rear retractable block, the pushing cylinder and upright columns form the direction-adjustable suspension top beam hydraulic support capable of being used independent, and a plurality of direction-adjustable suspension top beam hydraulic supports can be integrally connected through front connecting blocks and rear connecting blocks, thereby forming a direction-adjustable suspension top beam combined support. The direction-adjustable suspension top beam hydraulic support is simple in structure, convenient in combination, light in weight, high in strength, easy in direction-adjustment and strong in stability, and can be used for mechanical mining, blasting and roof coal caving mining working faces.

Description

But a kind of tuning hydraulic prop for moving suspended top beam

Technical field

The utility model relates to the support apparatus that a kind of colliery underground mining work plane uses, but is 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 purpose of this utility model 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.

The purpose of this utility model 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, the shank portion of T connector I is inserted into block I inside, T connector I right-hand member forms the vertical slippage with auxiliary girder vertical T type gathering sill and is connected, 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 the block I to handle the T connector I, realizes laterally transferring frame; The flexible piece in back is compared with the front stretching piece, and except that being provided with the ear seat in block II front side, other part-structures are identical, 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 of stretching is hinged, is used to control move frame; Preceding contiguous block is identical with back contiguous block structure, form by T connector II, block III, spacer pin, the T connector II can freely be stretched in the block III, stroke is subjected to the Position Control of spacer pin, but be used for the connection between a plurality of independence tuning hydraulic prop for moving suspended top beam, but constitute the suspended back timber sectional shelf-unit of tuning.

And form by girder, auxiliary girder, front stretching piece, the flexible piece in back, passing oil cylinder, can guarantee that the kinematic chain of girder, the vertical changing of the relative positions of auxiliary girder level, the vertical changing of the relative positions and horizontal cross tuning has constituted a kind of novel suspended adjusted device.

The beneficial effects of the utility model are: 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.

The specific embodiment

With reference to accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, the utility model mainly is made up of girder 1, auxiliary girder 3, column 6, front stretching piece 2, the flexible piece 5 in back, passing oil cylinder 4.Be respectively equipped with a horizontal guide slot and a vertical T type gathering sill that distributes up and down in girder 1 front portion, 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 3 front portions, both sides, rear portion; Front stretching piece 2 is made up of block I 9, spacer pin 10, T connector I 11, lifting ram 12, and the horizontally-guided head in block I 9 left sides forms horizontal sliding with girder 1 horizontal guide slot and is connected, and is used to guarantee the mutual changing of the relative positions in the horizontal direction of girder 1, auxiliary girder 3; The head of T connector I 11 constitutes the vertical slippage with the vertical T type gathering sill of auxiliary girder 3 and is connected, and is used to guarantee the mutual changing of the relative positions on vertical of girder 1, auxiliary girder 3; The shank portion of T connector I 11 is inserted into the inside of block I 9, and lifting ram 12 is arranged in the cavity of resorption of block I 9, and two ends are hinged with block I 9 and T connector I 11 respectively, and it is flexible in block I 9 to handle T connector I 11, is used to control the support tuning; The flexible piece 5 in back is compared with front stretching piece 2, and except that being provided with the ear seat in block II 13 front sides, other part-structures are identical, and the placement direction of the flexible piece 5 in back is opposite with front stretching piece 2 in the work; It is hinged to pass oil cylinder 4 one ends and auxiliary girder 3 right plates, and the other end is hinged with the block II 13 of the flexible piece 5 in back, is used to control the mutual changing of the relative positions in the horizontal direction of girder 1, auxiliary girder 3, realizes moving frame.
