Abstract
The utility model relates to a filling device for a pillar socket of a hydraulic support for coal mines, in particular to a filling block for a pillar socket of a hydraulic support base, which has the functions of preventing coal gangue and self-unloading coal gangue. The filling block is provided with a coal gangue self-unloading platform, and the slope of the coal gangue self-unloading platform is bigger than the repose angle of the coal gangue. Compared with traditional filling blocks for pillar sockets of hydraulic support bases, the filling device for the pillar socket of the hydraulic support base can avoid that the coal gangue goes down along a gap between the filling block and an upright pillar to block a working space of the upright pillar and to go onto a matched plane of the upright pillar and the pillar socket when the coal gangue accumulates on the filling block, and can avoid abrasive damage of the matched plane between the upright pillar and the pillar socket and the like. The filling block is applied for the pillar socket of the hydraulic support base, and is prominently characterized by functions of preventing the coal gangue and self-unloading the coal gangue. The filling block for the pillar socket of the hydraulic support base minimizes the coal gangue that goes along the gap between the filling block and the upright pillar, keeps the upright pillar swing flexibly inside the pillar socket, protects the upright pillar against obstruction by the coal gangue, and reduces abrasive damage of the matched plane between the upright pillar and the pillar socket.
Description
Technical field
The utility model relates to colliery hydraulic support needling device for filling, is specially a kind of filling piece of hydraulic support foundation needling.
Background technology
At present, hydraulic support needling filling piece exposed face is the plane, is easy to pile up fragmentary bastard coal, and fragmentary bastard coal leaks down along filling piece and column gap easily again, fill the working space of column and further invade the fitting face of column and needling, very improper.
The utility model content
The purpose of this utility model is to provide a kind of filling piece of hydraulic support foundation needling, the solution bastard coal is piled up, fragmentary bastard coal is filled the column working space of hydraulic support foundation needling top and the fitting face that a large amount of small grain size bastard coal enters column and needling, the problems such as wearing and tearing of aggravation column and needling fitting face.This device can replace present hydraulic support needling filling piece, prevents the bastard coal intrusion to greatest extent, ensures that column flexible swinging in needling is not hindered by bastard coal, slows down the wearing and tearing of column and needling fitting face.
The technical solution of the utility model is:
A kind of filling piece of hydraulic support foundation needling, this filling piece is provided with self-unloading bastard coal slide unit.
The filling piece of described hydraulic support foundation needling, the gradient of self-unloading bastard coal slide unit is greater than the angle of repose of gangue.
The filling piece of described hydraulic support foundation needling is offered porose on the filling piece.
The filling piece of described hydraulic support foundation needling, self-unloading bastard coal slide unit are the downward-sloping domatic structures in both sides.
The beneficial effects of the utility model are:
1, the filling piece of the utility model hydraulic support foundation needling is compared with present hydraulic support needling filling piece, can prevent that bastard coal from piling up on the filling piece, reduces the bastard coal intrusion amount of needling superjacent air space and column and needling fitting face to greatest extent.
2, the filling piece of the utility model hydraulic support foundation needling ensures that column flexible swinging in needling is not hindered by bastard coal, slows down the wearing and tearing of column and needling fitting face.
Description of drawings
Fig. 1 is the filling block structure schematic diagram of the utility model hydraulic support foundation needling.
Fig. 2 is installed in the hydraulic support schematic diagram for the filling piece of the utility model hydraulic support foundation needling.
Fig. 3 is the filling piece operating principle schematic diagram of the utility model hydraulic support foundation needling.
Among the figure, 1, the filling piece; 2, self-unloading bastard coal slide unit; 3, hydraulic support; 4, base; 5 bastard coals; 6, column; 7, filling piece and column gap; 8 column working spaces; 9, column and needling fitting face; 10, hole.
The specific embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
As shown in Figure 1, the filling piece concrete structure of the utility model hydraulic support foundation needling is as follows: filling piece 1 top is provided with self-unloading bastard coal slide unit 2, offer porose 10 on the filling piece 1, self-unloading bastard coal slide unit 2 is the downward-sloping domatic structures in both sides, and the gradient of self-unloading bastard coal slide unit 2 is greater than the angle of repose of bastard coal 5.
As Fig. 2-shown in Figure 3, filling piece 1 is installed in the base 4 of hydraulic support 3, and column 6 is plugged in the hole 10 of filling piece.When bastard coal 5 is fallen on the filling piece 1, because the gradient of self-unloading bastard coal slide unit 2 is greater than the angle of repose of bastard coal 5, bastard coal 5 can not be piled up on filling piece 1, overwhelming majority bastard coal 5 can be along self-unloading bastard coal slide unit 2 landings of filling piece 1, and sub-fraction bastard coal 5 enters into column working space 8 and column and needling fitting face 9 by filling piece and column gap 7.
Because the effect of the self-unloading bastard coal slide unit 2 of filling piece 1, bastard coal 5 quantity that enter into column working space 8 and column and needling fitting face 9 by filling piece and column gap 7 significantly reduce, when ensureing hydraulic support 3 cranes, column 6 flexible swinging are not subjected to bastard coal 5 to hinder the wearing and tearing that slow down column and needling fitting face 9.
