Description
Technical field
The utility model belongs to the coal mine machinery technical field, especially relates to retaining cash device between light-duty of a kind of half-edge coal seam work plane.
Background technology
By the magnitude classification of seam inclination, seam inclination is divided into gently inclined seam, inclined seam, half-edge coal seam both at home and abroad.Seam inclination is being gently inclined seam below 25 °, and 25 ° to 45 ° is inclined seam, is half-edge coal seam greater than 45 °.At present, tilt and half-edge coal seam is comprehensive adopts technology comprehensive to adopt technical development slow than gently inclined seam, and development gap is bigger, main cause is that seam inclination is big, after the rock of the local inbreak of the coal that the coal-face cutting coal machine is cut off, cash and coal-face top board falls in the coal-face hydraulic support, can roll fast or fly along the coal-face incline direction and scurry.Because out-of-flatness and coal, the cash out-of-shape etc. of coal-face base plate, coal, cash are in rolling fast or flying to scurry, at any time all might change in the hydraulic support that travel direction rolled into or scurried into fully-mechanized mining working, and the passage and the space of walking of the personnel in the fully-mechanized mining working surface hydraulic support and operation.In process of production, in case have coal, cash to roll in the hydraulic support that can scurry as fully-mechanized mining working, coal, cash roll fast downwards or fly to scurry along the passage of hydraulic support very easily again, and be untimely if personnel hide, will be therefore and injured or dead.Therefore, resolve inclined seam especially coal, the cash of half-edge coal seam fully-mechanized mining working fly to scurry the problem of hurting sb.'s feelings, be to be related to combine to adopt the important topic that safety guarantee is provided for half-edge coal seam.The hydraulic rack structure of existing fully-mechanized mining working use mainly is made of the back timber between the hydraulic pressure, front column, rear column, caving shield, front rod, back link, base both at home and abroad.Hydraulic support is installed full work plane continuously along the fully-mechanized mining working incline direction, between the front column and rear column of hydraulic support, has just formed the ramp way along tilt length.When coarse coal, cash were scurried in the hydraulic support, coarse coal, cash just might roll downwards or fly and scurry along the ramp way of hydraulic support, and the installation of the staff of below between the hydraulic pressure can't be protected.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of novelty simple in structure, can be reliably provides retaining cash device between light-duty of the half-edge coal seam work plane of safety guarantee for the mining activity personnel.
The technical solution of the utility model is as follows: retaining cash device between light-duty of a kind of half-edge coal seam work plane, comprise hydraulic support, its main points are: the back timber lower end at described hydraulic support is fixed with subplate, the subplate lower end is equipped with slide mechanism on this, sliding door is equipped with in the slide mechanism lower end on this, subplate lower end right part is fixed with door hanging on described, and the described sliding door of going up can move left and right; Be fixed with subplate down on the base of described hydraulic support, in described subplate upper end down lower sliding body be installed, sliding door is equipped with down in this lower sliding body upper end, and this time sliding door can move left and right.
