Abstract
The utility model relates to a frame lowing device which connects the left and the right top beams of a hydraulic support frame. A front and a back sliding blocks are respectively provided with a fixing plate (5) to form fixed connection with a top beam (2). A long through hole is arranged on each of the fixing plate (5) and sliding blocks (4), (7), a cylindrical pin (3) penetrates through the long through holes to connect the fixing plate (5) and the sliding blocks (4), (7). The sliding blocks (4), (7) and the top beam (1) form a sliding connection pair to connect the left and right top beams. An oil cylinder (6) is hinged with the front sliding block (4) by penetrating through the front end of the back sliding block, and the back end is hinged with the supporting seat plate of the top beam (1). The expansion and the contraction of the oil cylinder complete the walking action of the support frame. The left and the right beam bodies are lifted and lowered in the vertical plane and are supported at different heights. The utility model overcomes the phenomenon that the beam bodies roll when supported.
Description
The utility model relates to a kind of rack device that falls of hydraulic walking support, is the improvement at the syndeton in the support apparatus under the coal mine.Being specially adapted to the inclined seam stope uses.
In existing technology, a lot of hydraulic supports as " hydraulic prop for moving suspended top beam " (CN1067479A), " network type hydraulic support " (CN2069431U), " block form hydraulic prop for sliding mine caps " (CN2096643U) etc. device all form a unit hydraulic support by left and right two back timbers and hydraulic prop thereof.The left and right sides back timber of this class support connects by two groups of flexible quadric chains and finishes lifting reach process, flexible movements.Weak point is when roof cracking or other reason cause top board to rise and fall, and the back timber supporting surface then can cause left and right sides back timber face to form an angle along with local top board inclined plane tilts.Under the support of hydraulic prop, back timber rolls easily.Bring certain difficulty also for simultaneously the grasp of hydraulic pressure prop-setting angle.Be unfavorable for standardized management, the centralized Control hydraulic system is also made troubles.If be with tail boom to be used for the operation of caving coal, the easier tail boom that causes is swung, and structure member is turned round bad easily.
The purpose of this utility model is at above-mentioned weak point, designs a kind ofly new can finish thrust gear support lifting, reach, be particularly useful for the hydraulic support of working in the work plane of top board local dip and the local fluctuations of top board flexibly.
Scheme of the present utility model is as follows: propose a kind of new rack device that falls left and right back timber is coupled together.This slideway composition that falls front-slider, rear slider and a back timber of frame mechanism is slidingly connected and pays.The other end of slide block has long open-work, by straight pin slide block and the fixed head that also has long open-work that is fixed on another back timber is coupled together.Thereby left and right back timber is coupled together.Advance oil cylinder to pass the rear slider front end and be hinged on the front-slider, the rear end is hinged on propping up on the seat board on the left back timber.The flexible reach of taking a step of finishing support by oil cylinder.Simultaneously, can be upper and lower mobile owing to connect the straight pin of slide block and fixed head at long open-work, so that the back timber vertical lifting.
The utility model has the advantages that left and right back timber can support with different bearing heights, be adapted to therefore that top board tilts or broken and cause the work plane of the local fluctuations of top board; Because the lifting of beam body is carried out in vertical plane, so overcome the rollover phenomenon that the beam body causes because of the top board local dip when supporting; Hydraulic prop can support with any prop setting angle, is convenient to standardized management.And since the lifting of beam body in vertical plane, finish, think that whole connections of entire working surface provide rational basis.
Below in conjunction with accompanying drawing the utility model is illustrated.
Fig. 1 is the forward and backward vertical view that falls frame mechanism.Fig. 2 is the one group of elevation that falls frame mechanism in back.
This falls frame mechanism and connects the left back timber (1) of a unit support, right back timber (2).Front-slider (4), rear slider (7), propelling oil cylinder (6), straight pin (3), fixed head (5), caging bolt (8) is formed this and is fallen frame mechanism.All have long open-work on fixed head (5), slide block (4), (7).Two straight pins (3) couple together fixed head (5) and slide block (4), (7).Slideway 11 compositions of slide block (4), (7) and back timber (1) are slidingly connected.On fixed head, also has a guide strip (9) simultaneously.Screw rod (8) passes another long open-work on the slide block and is fixed on the guide strip (9) on the fixed head.Along the upper and lower slip of guide strip, avoid the beam body to tilt with the slide block end face of beam body lifting.Advance sliding cylinder (6) to pass rear slider (7), an end is hinged on the front-slider (4).The other end is hinged on the seat board (11) of back timber (1).When back timber (2) lands, advance oil cylinder (6) elongation to drive back timber (2) reach.Be support with back timber (2) then, back timber (1) landing advances oil cylinder (6) to shrink and drives back timber (1) reach, and back timber (1) supports the reinstatement attitude, finishes the distance of taking a step.
Claims (1)
1, the hydraulic walking support frame mechanism falls, it is characterized in that the above-mentioned frame mechanism that falls is by front-slider (4), rear slider (7), fixed head (5), straight pin (3), screw rod (8) is formed, front and back slide block (4), (7) respectively there is a fixed head (5) to fixedly connected with back timber (2), two fixed heads (5), slide block (4), (7) all have long open-work, two straight pins (3) pass slide block (4), (7) and the long open-work of two fixed heads (5) the two is coupled together, slide block (4), the slideway (11) of the other end (7) and back timber (1) constitutes to be slidingly connected to be paid, an end that advances oil cylinder (6) to pass rear slider (7) is hinged on the front-slider (4), the other end is hinged on the front-slider (4), the other end is hinged on the seat board (12) of back timber (1), said fixing plate (5) has a guide strip (9) to fixedly connected with fixed head, and screw rod (8) passes slide block (4), (7) the long open-work of another is with slide block (4), (7) be fixed on the guide strip (9).
