Technical field
The utility model relates to comprehensive mechanical coal mining face timbering equipment under the coal mine, and relating to a kind of coal seam thickness that is applicable to specifically is the thin coal bed fully-mechanized mining face board plug type hydraulic support of 0.65～0.91m.
Background technology
The shared reserves of China's girdle are 17.5% of gross reserves, many mining areas particularly south and southwest girdle are main mining coal seams, but for girdle, particularly coal seam thickness is the special girdle of 0.65～0.9m, the general coal-mining method of adopting of most of now employing, labor strength is big, poor stability, inefficiency, the rate of extraction is low, along with the appearance that the policy of the safety and the rate of extraction improves to coal production in country, comprehensive mechanical coal mining will be the main coal-mining method of thin seam working surface.As the development of the hydraulic support of one of main corollary equipment of thin coal bed fully-mechanized mining is that China's thin seam working surface is combined and adopted one of main task of technical development.Because the coal seam is thinner, the support minimum altitude is lower, is 0.65～0.91m, and this moment, each ingredient of support was interfered easily.So, specific (special) requirements has been proposed for the structure of thin seam working surface support for avoiding parts interference, guarantor's row of channels, ventilation section, cross the machine height and alleviate workman's manual labor and improving problems such as safe coefficient, operating efficiency, output.
Summary of the invention
That the purpose of this utility model provides at the problems referred to above just is a kind of simple in structure, the thin coal bed fully-mechanized mining face board plug type hydraulic support of superior performance.
The purpose of this utility model can adopt following measure to realize:
Thin coal bed fully-mechanized mining face board plug type hydraulic support of the present utility model comprises base and back timber, upper/lower terminal all directly is supported on column between base and the back timber by articulated manner, be provided with the back card/back board that extends straight down in the rearward end of back timber, the lower end of described back card/back board is inserted into and is arranged in base rear end portion and the plate guide groove that shape of cross section back card/back board matches; The setting of back card/back board can prevent that the spoil in goaf from tumbling work plane, plays the effect of shielding.
The first half of base described in the utility model is provided with the ∏ shape space of open front, this ∏ shape space is between left and right column, on postmedian two side, ∏ shape space, be symmetrical arranged to be useful on the engaging lug seat of passing jack is installed, the thrust gear of being made up of passing guide frame and the passing jack that is seated in the passing guide frame is installed in the ∏ shape space, wherein, pass jack rear end and engaging lug seat and be hinged, pass the jack front end and be hinged by bearing pin and the left and right sides engaging lug of passing the guide frame front end and the ear seat of transporter.(with the passing jack of hydraulic support in the prior art and to pass the mounting means of guide frame different, pass preposition the making of jack and pass jack and directly withstand conveyer).
Back timber described in the utility model adopts the ultra-thin monolithic high strength back timber of not establishing side guard board, and the back timber front end be plank frame (so-called monolithic---promptly be different from prior art, front end does not have extensible canopy), this structure not only can be simplified simply, and helps reducing cost and increase the pedestrian space.
Base described in the utility model adopts first half to open the thin cross section structure of high strength of crotch, intermediate thin body structure, and described base is an elongate structure.The purpose of this structure is in order to increase the pedestrian space equally.
The utility model has following beneficial effect compared to existing technology:
The setting of back card/back board described in the utility model and base rear portion plate guide groove, can be in the supporting process of back timber, along with stretching of column, back card/back board can prevent back timber front and back slippage better under the effect of the plate guide groove of base, make back timber do motion straight up and down, the back timber front end does not have side-play amount, is beneficial to the supporting to top board, and can prevent effectively that the spoil in goaf from tumbling work plane.
The structure that back timber in the utility model adopts whole ultrathin type, front end not to have extensible canopy, do not establish side guard board, mainly be to improve its end load to guarantee the top board integrality, do not take place or can not occur the place ahead roof fall problem substantially, and ultrathin back timber is except that guaranteeing its walkway, it is necessary also to be that coal-winning machine is crossed the machine height, back timber has been cancelled side guard board, both simplified the structure like this, also alleviated the weight of support, advancing fast and strengthening on the basis of work plane management, basically the inbreak of top board can not occur, be a kind of technical measures that The afvantages outweigh the disadvantages therefore.
For satisfying the girdle coal work in the face of ventilation section, remarkable space, the specific (special) requirements of machine height excessively, back timber described in the utility model and base have all been taked the lengthening measure, adopted high-strength plate, the thin box structure of optimizing, even be plank frame at the back timber front end, when guaranteeing support main member intensity attenuate the cross dimensions of back timber and base; In addition, the design that adds microscler base can make its front end specific pressure little, and end phenomenon appears gnawing in front end when preventing to move frame.
In sum, the utility model not only can make structure more simplify, be convenient to safeguard, again can be in the supporting process of back timber, along with stretching of column, back card/back board can prevent back timber front and back slippage better under the effect of the plate guide groove of base, make back timber do motion straight up and down, and the back timber front end does not have side-play amount, be beneficial to supporting, and can prevent effectively that the spoil in goaf from tumbling work plane top board.
