Description
Technical field
The utility model relates to pit gear field, specifically, relates to a kind of mining roller shutter type support template.
Background technology
It is shaping etc. that the molding mode adopted in current main flow edge air gallery technology mainly contains filling rack forming, shaping, the soft mould supporting of filling template.Affect by the large situation of current domestic coal, cost-saving, expansion benefit becomes the important means that numerous coal enterprise resists market pressure, makes up deficits and shake off poverty, although gob side entry retaining has can save develop cost, alleviate coal mine excavation to continue the plurality of advantages such as nervous contradiction, but the initial stage that is subject to drop into comparatively large, the problems such as certain influence can be produced to normal advance of the face degree and constrain propagation and employment.
Therefore, how to reduce the support cost of gob side entry retaining, reduce gob side entry retaining and the problem that those skilled in the art need solution badly is become on the impact that work plane normally advances.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of mining roller shutter type support template.This device, by designing brand-new structure, can make support template rapid shaping in tunnel, improve the construction efficiency of follow-up supporting, and is convenient to transport.
In order to reach above-mentioned purpose, the utility model adopts following technical scheme:
A kind of mining roller shutter type support template, comprising: filter cloth, the side of filter cloth is connected with some reinforcing ribs, and metal tube is fixed between reinforcing rib and filter cloth by reinforcing rib;
The shell of described metal tube run through by wire, wire and metal tube are jointly formed as filling bag and fill grid frame when being in the milk.
Preferably, described filter cloth is antistatic filter cloth.
Preferably, described metal tube is square steel pipe.
Preferably, described wire is steel wire.
The utility model additionally provides a kind of supporting method utilizing above-mentioned support template, comprises the steps:
A, multiple support template is transported in mine laneway, then utilizes hydraulic prop to drive the end wiry on wherein two support templates rises until fit with roof and hold out against;
B, hoist after the 3rd support template horizontal development, the length of the localization part overlapping with the support template of vertical direction of the support template after hoisting is not less than 100mm;
C, for horizontal direction support template increase monomer column as support.
In above-mentioned supporting method, the gap between monomer column and grid frame, fills up with plank.
The beneficial effects of the utility model are:
(1) connected by square steel pipe by steel wire, it is tight on filter cloth that square steel pipe is reinforced muscle, and the distance between adjacent steel pipe can adjust, and is convenient to reduce overall volume, facilitates down-hole to carry;
(2) during vertical direction supporting by the quick one-shot forming of the jacking of hydraulic column, without the need to splicing, shorten time of spending of support template when building follow-up supporting;
(3) support template one-shot forming, gob side entry retaining wall body structure is stablized;
(4) total quality is less, the labour intensity that can greatly reduce a staff.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment 1: a kind of mining roller shutter type support template, its structure as Figure 1-4: comprise filter cloth 1, the side of filter cloth 1 is connected with many reinforcing ribs 4, reinforcing rib 4 by tight for the metal tube 2 of many horizontally sets between reinforcing rib 4 and filter cloth 1;
The wire 3 that described metal tube 2 is parallel to described reinforcing rib 4 axis direction run through, and wire 3 and metal tube 2 are jointly formed as filling bag and fill grid frame when being in the milk.
Described filter cloth 1 can select high strength, fire-retardant and anlistatig filter cloth, and metal tube 2 is square steel pipe, and wire 3 is steel wire.
The manufacture method of this support template is: the maximum effective size of template of support template is designed to 3000mm × 2220mm, metal tube 2 uses length for 3000mm, 20mm × 20mm square tube of wall thickness 1mm, the spacing 200mm of adjacent metal tube 2, on metal tube 2, drilling hole is apart from 560mm.Metal tube 2 is linked together through the boring on metal tube 2 with the wire 3 that diameter is ф 6mm.Form template net framework.
By grid frame for providing shaping supporting when filling bag filling is in the milk.Grid frame outer side covers high-strength anti-flaming, antistatic filter cloth, have wear-resisting, corrosion-resistant, uvioresistant, the performance such as fire-retardant, antistatic, reduce the deflection after filling bag grouting further, prevent skeleton ledge from damaging filling bag simultaneously.
Filter cloth 1 carries out edge sealing process with the junction of metal tube 2.
In above-mentioned support template, relevant parameter is calculated as follows:
1. 20mm × 20mm thickness 1mm square tube, unit mass is: 0.5966Kg/m, 11 3m rectangular pipe gross mass 19.69Kg;
2. ф 6mm wire rope unit mass is 0.146Kg/m, 6 long finer wire gross mass 2.19Kg of 2.5m;
3. high-strength anti-flaming, antistatic filter cloth are about 8m
2, gross mass is about 1Kg.
Then specification is that 3m × 2m support template gross mass is about 25Kg, can be carried by a staff in down-hole completely.
While providing structural concept, the utility model additionally provides one and utilizes above-mentioned mining roller shutter type support template to carry out supporting method, comprises the steps:
A, multiple support template is transported in mine laneway, then utilizes hydraulic prop to drive the end of the wire 3 on wherein two support templates rises until fit with roof and hold out against;
B, hoist after the 3rd support template horizontal development, the length of the localization part overlapping with the support template of vertical direction of the horizontal support template after hoisting is not less than 100mm;
C, for horizontal direction support template increase monomer column as support.
In above-mentioned supporting method, the gap between monomer column and grid frame, fills up with plank.
After this programme adopts said structure, with existing support template, quality is lighter, supporting is more convenient, effectively raises operating efficiency and decreases labour intensity.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of embodiment, General Principle as defined herein can when not departing from spirit or scope of the present utility model, realize in other embodiments, the part be not described in detail, for prior art, do not repeat at this.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and feature.
