Abstract
The utility model provides a telescopic hydraulic support of curb plate, back back timber both sides be provided with vertical decurrent curb plate, curb plate lower extreme and hydraulic support's base fixed connection, the curb plate be vertical telescopic setting, highly follows base and the back distance between the back timber, back back timber afterbody still be provided with waste rock retaining plate, the waste rock retaining plate below sets up the shielding roof beam, shielding roof beam upper end be connected with back back timber rotation, the lower extreme passes through the connecting rod and is connected the setting with the base. Telescopic hydraulic support of curb plate, set up the curb plate between back back timber and base for the support afterbody is totally enclosed structure, can act as to fill the support NOT AND and fill the transition support between the support, the utility model discloses the curb plate is except stopping the waste rock about hydraulic support, can also serve as solid and the shaping of fluidic obsturator such as the solid that fills various differences, gao shui, lotion, sets up the telescopic curb plate simultaneously, can adapt to the operational environment of different bearing heights.
Description
Technical field
The utility model relates to hydraulic support technical field, is specially a kind of side plate telescopic hydraulic support.
Background technology
Hydraulic support is that a kind of fluid pressure generation support force that utilizes also realizes automatically moving a kind of hydraulic power unit of establishing to carry out roof timbering and management, and being used for using in coal mining underworkings, is the indispensable corollary equipment of comprehensive mechanical coal mining.
In the support of existing band side plate, it is only the spatial placement side plate between back link and base, function singleness, small part spoil can only be stoped in exploitation to enter hydraulic support afterbody, and fixed side plate effectively can not close candidate space, easily cause the spoil in goaf to pour in, and if need the mining environment height that supports different, then can not use flexibly, thus cause the waste of resource and the difficult management of work plane.
Utility model content
The purpose of this utility model is to provide a kind of side plate telescopic hydraulic support, by back timber after hydraulic support and base both sides completely closed, pouring in of goaf spoil can be organized, can be used as transition bracket to use, and two side shields are set to telescopic, the working environment of different bearing height can be adapted to.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of side plate telescopic hydraulic support, the base of hydraulic support is arranged and organizes hydraulic jack more, the front back timber that hydraulic jack upper end support level connects and rear back timber, described rear back timber both sides are provided with side plate straight down, side plate lower end is fixedly connected with the base of hydraulic support, side plate is vertical telescopic setting, and height changes with the distance between base and rear back timber; Described rear back timber afterbody is also provided with waste rock board, arranges caving shield below waste rock board; Described caving shield upper end and rear back timber are rotationally connected, and lower end to be connected with base by connecting rod and to arrange.
Described rear back timber is the rear back timber of lengthening formula.
The hydraulic jack that described base is arranged has many groups, and often group arranges two, back timber before having at least a group to support, back timber after having at least two groups to support.
Described side plate is three pieces of wide baffle plates be arranged in order from top to bottom, from outside to inside, partly overlaps and be slidably connected between baffle plate and baffle plate.
Compared with prior art, the utility model has following beneficial effect:
A kind of side plate telescopic hydraulic support described in the utility model, between rear back timber and base, side plate is set, support afterbody is made to be full-closed structure, the transition bracket between filling support and non-filling support can be served as, fill support afterbody side for stoping goaf spoil to move to opposite side, spoil can also be stoped to pour in from goaf to internal stent, this use new type hydraulic bearer left side plate is except stopping spoil, the various different solid of filling can also be served as, Gao Shui, the obturation of the solids such as lotion and fluid is shaping, telescopic side plate is set simultaneously, the height of side plate changes along with the height change of hydraulic jack, the working environment of different bearing height can be adapted to.

Fig. 2 is the lateral plate structure schematic diagram of a kind of side plate telescopic hydraulic of the utility model support;
Mark in figure: 1, front back timber, 2, rear back timber, 3, caving shield, 4, connecting rod, 5, base, 6, side plate, 7, waste rock board, 8, hydraulic jack.
Detailed description of the invention
Below in conjunction with accompanying drawing, by detailed description of the invention, the utility model is further described.
A kind of side plate telescopic hydraulic support as described in Figure, the base 5 of hydraulic support is arranged many group hydraulic jack 8, the front back timber 1 that hydraulic jack 8 upper end support level connects and rear back timber 2, described rear back timber 2 both sides are provided with side plate 6 straight down, side plate 6 lower end is fixedly connected with the base 5 of hydraulic support, side plate 6 is vertical telescopic setting, and height changes with the distance between base 5 and rear back timber 2; Described rear back timber 2 afterbody is also provided with waste rock board 7, arranges caving shield 3 below waste rock board 7; Described caving shield 3 upper end and rear back timber 2 are rotationally connected, and lower end is connected with base 5 is arranged by connecting rod 4.
Described rear back timber 2 is the rear back timber of lengthening formula, whole support total length than common protected type and chock shield length long, be close with filling stent length.Hydraulic support described in the utility model both can be used for work plane and had carried out part or sublevel fill stoping, also can be used as gob side entry retaining support with other support equippeds and use.
The hydraulic jack 8 that described base 5 is arranged has many groups, often group arranges two, back timber 1 before having at least one group to support, back timber 2 after having at least two groups to support, why this hydraulic support strengthens top plate supporting intensity, to reach filling side top board in time across falling, being convenient to top board in time across falling, prevent from damaging obturation part by pressure.
Described side plate 6 be three pieces from top to bottom, the wide baffle plate be arranged in order from outside to inside, partly overlap between baffle plate and baffle plate and be slidably connected, also can the more baffle plate of magnitude setting according to actual needs, arrange from top to bottom, time hydraulic jack 8 changes bearing height, change direction parallel with the moving direction of baffle plate, being arranged in order setting is from outside to inside in the gap in order to prevent the spoil dropped from eminence from sticking between baffle plate and baffle plate, partly overlap between baffle plate and baffle plate, the height of side plate 6 can be compressed to greatest extent, thus use the working environment of different bearing height demand to greatest extent.
