Abstract
The utility model discloses a combine and to adopt on working face corner windbreak and build and establish module, include: protection surface course, rectangle light block, hand (hold), inside square frame frame, protection surface course closely parcel at the inside fixed inside square frame frame that is provided with of rectangle light block, are provided with two hand (hold)s at the lateral wall of rectangle light block on the surface of rectangle light block, and it is inside and fixed with inside side frame attach that the stiff end of two hand (hold)s stretches into rectangle light block. Can be under construction fast and go up the corner windbreak, have workman low in labor strength, construction speed is fast, coal production influence characteristics such as less.
Description
technical field:
The utility model relates to and belongs to coal mine fully-mechanized mining working gas at upper corner treatment facility technical field.
background technology:
Gas at upper corner extraction is the effective ways that improvement coal face gas at upper corner gathers, and often sets windbreak at upper corner, gas is effectively assembled and is beneficial to carry out gas drainage under suction in actual mechanical process.At present at the coal-face back production initial stage, the mode with knitting bagged filling broken coal is piled up layer by layer at upper corner is taked to set windbreak, it is tight that windbreak gap will use yellow mud to smear, back is close at windbreak top, and upper side is close on return airway and helps, and lower side is closely connected with last support, keeping out the wind, coping installs flexible pipe, Lao Tang side is stretched in one end, and the other end is connected with return airway being helped releasing pipe, realizes the uninterrupted gas extracted windbreak rear portion out and gather.Windbreak moves forward with the advance of the face, often moves frame once, need tear open, build windbreak once.Adopt the method management and control gas at upper corner, Be very effective, but because return aircourse section is large, base establishes windbreak area comparatively large, and for completing this work, coal pillar robbing group need arrange the responsible upper corner of several workman sole duty to tear open in production class, builds windbreak and smear tight with yellow mud paste, cause labor strength large, engineering time is long, and during tearing open, building windbreak, work plane must not carry out machine adopt work also coal affect coal production.
utility model content:
The purpose of this utility model is to provide the fully-mechanized mining working upper corner windbreak base that a kind of labor strength is low, speed of application is fast and establishes module.
To achieve these goals; the utility model comprises: protection surface layer, rectangle lightweight block, hand handle, internal side framework; protection surface layer is closely wrapped in the surface of rectangle lightweight block; internal side framework is fixedly installed at rectangle lightweight bulk inner; the sidewall of rectangle lightweight block is provided with two hand handles, and the fixed end of two hand handles extend into rectangle lightweight bulk inner and is connected and fixed with internal side framework.
Like this, when needs establish windbreak to draw out methane at fully-mechanized mining working upper corner base, hand handle of the present utility model can be lifted by workman, windbreak is set in the mode of piling up layer by layer, because this module weight is light and specification is neatly rectangular, what workman will take too large strength very soon and not sets windbreak, neatly between module combines closely, do not need yet again with yellow mud stick with paste smear tight.There is the features such as labor strength is low, speed of application fast, and coal production impact is less.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
detailed description of the invention:
As shown in Figure 1, the utility model comprises: protection surface layer 1, rectangle lightweight block 2, hand 3, internal side framework 4, protect surface layer 1 to be closely wrapped in the surface of rectangle lightweight block 2.Protection surface layer 1 can adopt mining ventilating tunnel cloth material; the antistatic anti-flame-retardancy requirements of underground coal mine can be met; durable moisture proof again; rectangle lightweight block is played a protective role and improves bulk strength; rectangle lightweight block 2 can adopt polyurethane gas sealing material; the antistatic anti-flame-retardancy requirements of underground coal mine can be met, making of conveniently drawing materials again.Be fixedly installed internal side framework 4 in rectangle lightweight block 2 inside, be provided with two hands 3 at the sidewall of rectangle lightweight block, the fixed end of two hand handles extend into rectangle lightweight block 2 inside and is connected and fixed with internal side framework 4.Internal side framework 4 and hand adopt steel bar meter to make 3.Actual production adds man-hour; first processing cuboid mould is made; internal side framework 4 is arranged on mould inside; hand is reserved in exterior side wall 3; mould inner wall lays protection surface layer 1; pour mould inside into by after polyurethane two kinds of reaction raw materials mixing and stirring, remove mould through reaction after a while after solidifying and form the utility model product.The large I of specification of the present utility model makes series of products as required.
