Background technology
Present domestic use hydraulic prop for moving suspended top beam is to add a kind of coal-face support apparatus between articulated roof beam and the fully mechanized mining supporter between hydraulic prop, have fit long-pending little, in light weight, compliance strong, can realize the characteristics that oneself moves, be widely adopted at some medium and small collieries.It links together left and right sides back timber by flexible four connecting rod slipping mechanisms in frame, there is not base, there is not linkage between the adjacent frame, in use, occur easily crooked, fall frame, buried column, insert problems such as the end, frame takes place when a support particularly, the adjacent frame of very easier initiation falls frame, form chain reaction, ordinary production and personal security are constituted a serious threat.
Summary of the invention
The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of, band base that large inclination working surface use big at hag plate, pressure is provided, and can effectively avoid occurring inserting the end, buried column problem, the suspended back timber sectional shelf-unit of high stability.
The purpose of this utility model can realize by following technical measures:
A kind of suspended back timber sectional shelf-unit mainly is made up of girder, auxiliary girder, column, base, front-slider, rear slider and passing oil cylinder.
Between base and girder or auxiliary girder, two to three columns are set, the column two ends are connected by ball pivot or bearing pin with both respectively, girder, the right side of auxiliary girder is equipped with former and later two verticals T type gathering sill, the left side upper cover plate, the lower cover edge is equipped with horizontal guide slot, front-slider, rear slider passes through bearing pin or bolt rigid connection by T connector and block respectively, its right-hand member is the horizontally-guided head, forming horizontal sliding with the girder horizontal guide slot is connected, play the guide effect that support is passed, left end is a T type guide head, forming the vertical slippage with the vertical T type of auxiliary girder beam chute is connected, guarantee girder, the auxiliary girder changing of the relative positions mutually up and down hoists, fall the frame guide effect, it is hinged to pass oil cylinder one end and front-slider, ear seat on the other end and the girder right plate is hinged, uses when moving frame.
Because suspended back timber sectional shelf-unit is provided with base, waste rock board or retaining cash curtain also can be set on base or rear column, can avoid inserting the end and buried column phenomenon to a great extent.
The beneficial effects of the utility model are: by forward and backward slide block and major and minor beam and pass oil cylinder and constituted novel thrust gear, can form a kind of novel basic suspended bar timber cell cube, a plurality of suspended bar timber cell cubes are linked to be an integral body by extraordinary slide block again, constitute suspended back timber sectional shelf-unit.That this support has is simple in structure, combined and instant, in light weight, intensity is high, stability is strong, is convenient to adorn, tears open, operates industry, can be used for that machine is adopted, big gun is adopted, the caving coal mining work plane, is particularly useful for the stope of hag plate, inclined seam.

The specific embodiment
With reference to accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, embodiment of the present utility model mainly is made up of girder 1, auxiliary girder 2, column 3, base 4, front-slider 5, rear slider 6, passing oil cylinder 7.Base 4, girder 1 or auxiliary girder 2 adopt ball pivot or bearing pin to be connected with column 3 respectively, front-slider 5 and rear slider 6 right-hand members are the horizontally-guided head, left end is a T type guide head, the right side of each girder 1 and auxiliary girder 2 is provided with former and later two verticals T type gathering sill groove, the left side upper cover plate, the lower cover edge is provided with horizontal guide slot, front and back slide block 1, the right-hand member horizontally-guided head of rear slider 2 forms horizontal sliding with girder 1 horizontal guide slot and is connected, other end T type guide head forms the vertical slippage with auxiliary girder 2 vertical T type gathering sills and is connected, simultaneously with girder 1, auxiliary girder 2 laterally links together, it is hinged to pass oil cylinder 7 one ends and front-slider 5, ear seat on the other end and girder 1 right plate is hinged, one group of girder 1, auxiliary girder 2, column 3, base 4, front-slider 5, rear slider 6 and passing oil cylinder 7 primordials suspended bar timber cell cube originally, a plurality of suspended bar timber cell cubes are pressed girder, auxiliary girder, girder, auxiliary girder is arranged in proper order, couple together with rear slider 6 or front-slider 5 between the cell cube and just be linked to be an integral body, constitute suspended back timber sectional shelf-unit.
Course of action of the present utility model is as follows: several suspended back timber sectional shelf-units are arranged by girder, auxiliary girder order successively along stope, control column 3 setting props, make girder 1, auxiliary girder 2 roof supportings, and keep certain support force, support enters duty.When needs move frame, as moving frame from right to left successively from a certain suspended back timber sectional shelf-unit, at first control first suspended bar timber cell cube of right number and move frame, 2 times box type columns of auxiliary girder 3 are unloaded the post that contracts, make auxiliary girder 2, base 4 breaks away from top board respectively, the base plate certain distance, control this cell cube and pass oil cylinder 7 stretching, extensions, piston rod promotes front-slider 5 and drives auxiliary girder 2 reaches, after arriving assigned position, control 2 times box type column 3 setting props of auxiliary girder, up to its auxiliary girder 2, base 4 contacts top board respectively, the floor, and keep certain support force, enter the support works state, the column 3 of controlling this cell cube girder 1 below then unloads the post that contracts, and makes girder 1 and base 4 break away from top board respectively, the base plate certain distance is controlled and is passed the oil cylinder contraction, 1 reach of cylinder body pulling girder, after arriving assigned position, control column 3 setting props, up to its girder 1 and base 4 contact top boards thereof, the floor, keep certain support force, enter the support works state; Then control second suspended bar timber cell cube and move frame, move frame up to this suspended back timber sectional shelf-unit and all finish according to above program; If move frame from left to right, must be according to every the beam moving manner, promptly move frame by moving the order that moves girder 1 behind the auxiliary girder 2 earlier.
