Abstract
The utility model provides a mining umbrella stull comprises floorbar and umbrella -type hydraulic prop, and wherein the floorbar is for the cuboid form, and the floorbar can prevent tunnel pucking phenomenon effectively, the column cap is equipped with the hydraulic pressure post for the umbrella -type hydraulic prop of crew cut style includes the base on, the top of hydraulic pressure post is equipped with the back timber, and the lateral part pin joint of back timber has the umbrella board, is connected with the pneumatic cylinder between back timber and the umbrella board, and when the umbrella board was propped up by the pneumatic cylinder, the umbrella board among every umbrella -type hydraulic prop just can dock mutually and coincide with the back timber to the mesh is strutted in the completion, the utility model discloses the flexibility is high, and each parts all can be dismantled, adopts the umbrella board to strut, has increased the lifting surface area, has reduced the pressurized, can use umbrella board and each umbrella board of the different quantity of different umbrella face sums of products as required instead and is radial scattering strutting the in -process, and the atress is even, and stability is strong.
Description
Technical field
This utility model relates to apparatus field, mine, particularly relates to a kind of mining umbrella stull.
Background technology
At present, hydraulic support product divides by work surface condition, it is possible to be divided into the simple rack of conventional face and the comprehensive mining hydraulic bracket of fully-mechanized coalface.Simple rack developed quickly in recent years, in succession emerge a lot of frame type, such as slippage bracket, cantilever support and sectional shelf-unit etc., but all there are some such or such problems, support stability such as slippage bracket and cantilever support is poor, it is susceptible to down partially, needs during coal mining to lay top net, just can play corresponding support action；Sectional shelf-unit is linked to be an entirety, although bracket support ability is relatively good, but owing to globality is higher thus limiting motility, make to have in operation many constant, additionally that face roof flatness requirement is too high, and require that tunnel must be vertical with work surface, flexibility ratio is poor, and cause be difficult to reach theory support intensity owing to being linked to be entirety between support, bring potential safety hazard to working face mining.
Utility model content
The purpose of this utility model is in that to provide a kind of mining umbrella stull, with the problem solving to propose in above-mentioned technical background.
For achieving the above object, this utility model provides following technical scheme:
A kind of mining umbrella stull, is made up of bottom girder and umbrella shape hydraulic prop, and wherein bottom girder is rectangular-shaped, and bottom girder can be effectively prevented Floor Heave in Roadway phenomenon；The umbrella shape hydraulic prop that stigma is cab over type includes base, base is provided with hydraulic column, the top of hydraulic column is provided with back timber, the sidepiece of back timber is articulated with umbrella plate, it is connected to hydraulic cylinder between back timber and umbrella plate, when umbrella plate is propped up by hydraulic cylinder, the umbrella plate in each umbrella shape hydraulic prop will dock mutually and coincide with back timber.
As the further technical scheme of this utility model, umbrella shape hydraulic prop stigma is be provided with the flat needling of forging suited mutually with umbrella shape hydraulic prop stigma on cab over type and base.
As the further technical scheme of this utility model, hydraulic cylinder is connected with back timber by square shaft and cylinder bottom is cab over type.
As the further technical scheme of this utility model, each umbrella plate afterbody all forge tangent with back timber and half groove.
Compared with prior art, this utility model motility is high, all parts is all detachable, adopt umbrella slab supporting, increase lifting surface area and decrease pressurized, can using different umbrella plate areas in Bracing Process as required instead and use multiple umbrella plates and each umbrella plate to scatter radially uniform force, stability is strong.
Accompanying drawing explanation
Fig. 1 is a kind of mining umbrella stull front view of this utility model, Fig. 2 is a kind of mining umbrella stull side view of this utility model, Fig. 3 is a kind of mining umbrella stull top view (using two umbrella plate situations) of this utility model, and Fig. 4 is a kind of mining umbrella stull top view (using four umbrella plate situations) of this utility model.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of mining umbrella stull, be made up of bottom girder 1 and umbrella shape hydraulic prop, wherein bottom girder 1 is rectangular-shaped, and bottom girder 1 can be effectively prevented Floor Heave in Roadway phenomenon and ensure the stability of support；Stigma is the umbrella shape hydraulic prop of cab over type, including base 2, base 2 is provided with the flat needling of forging suited mutually with umbrella shape hydraulic prop stigma, and base 2 is provided with hydraulic column 3；The top of hydraulic column 3 is provided with back timber 6, the sidepiece of back timber 6 is articulated with umbrella plate 4, and back timber 6 arranges multiple notch connecing umbrella plate 4, operationally can increase umbrella plate 4 quantity in time according to on-the-spot supporting demand, thus completing different supporting demands, reduce the loss because supporting brings；In Bracing Process, umbrella plate 4 scatters in radial, uniform force, increases contact area, reduces pressurized；Being connected to hydraulic cylinder 5 between back timber 6 and umbrella plate 4, hydraulic cylinder 5 cylinder bottom is cab over type, and hydraulic cylinder 5 is connected with back timber 6 by square shaft 7；When umbrella plate 4 is propped up by hydraulic cylinder 5, umbrella plate 4 phase in each umbrella shape hydraulic prop is docked and coincide with back timber 6, forms the effect of Fig. 3, Fig. 4, thus playing effective supporting purpose.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, it is also possible under the premise without departing from this patent objective, make various change.
Claims (4)
