Abstract

The utility model relates to a shock resistant stack type bracket, comprising an upper cross beam, a lower cross beam and a large-flow stainless steel double safety valve. The bracket is characterized by also comprising top beams, bases and upright posts, two ends of the upper cross beam are respectively connected with the top beams above the upright posts on two sides of the cross beam, the top beams are connected with piston rods of the upright posts, a base of an upright post cylinder is arranged in the base, bases on two sides are connected with the lower cross beam, and the upright post cylinder body is provided with the large-flow stainless steel double safety valve. The shock resistant stack type bracket can permanently protect mine laneways with various shock ground pressure (mine shock) or large periodic pressure, and protect the safety of underground workers and the laneways. The bracket belongs to the field of mine machinery manufacture and application.

Description

The protecting against shock brettis

Technical field:

The utility model relates to a kind of protecting against shock brettis, and this kind support can carry out permanent support various suffering in the big mine laneway of bump (ore deposit shake) or cycle pressure, the safety of equipment in protection underground labour and the tunnel.Belong to mining machinery manufacturing and application.

Background technology:

In the mine of modern fully-mechanized mining, especially in the stope of coal mines, continuous increase along with mining depth, geological condition is complicated all the more, not only the ore deposit, down-hole is pressed and is increased, part mining area even the bump (also claim small-sized earthquake or ore deposit shake) of omen occurs having no causes serious casualties and property loss.International, domestic at present reliable method and the equipment that does not all have this type of burst of reply or abominable natural situation generation.

Summary of the invention:

The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and provides a kind of scientific structure reliable and meet the protecting against shock brettis that condition is installed and used in the down-hole.This protecting against shock brettis comprises top rail, lower transverse beam and big flow stainless steel double safety valve, it also comprises back timber, base and column, the two ends of above-mentioned top rail link to each other with the back timber of two heel posts top respectively, back timber links to each other with the column piston rod, column cylinder bottom seat is in base, two wing bases link to each other with lower transverse beam, and the cylinder body of column is provided with big flow stainless steel double safety valve.

Described top rail be the cuboid casing, in the stiffener structure is arranged, respectively there is an ear seat at two ends; Described back timber be cuboid, in establish two flat needlings and link to each other with the column piston rod with pin-and-hole, a side has the ear seat that can be connected with top rail; The cylinder bottom of column and piston rod column cap are flat form; Two flat needlings are arranged in the base, be provided with the rubber that resets with column cylinder body contact portion; Lower transverse beam be the cuboid casing, in the stiffener structure is arranged, two ends link to each other with base respectively by bearing pin; Big flow stainless steel double safety valve is connected on the column cylinder body.

The utlity model has following characteristics:

1, all connections are simple bearing pin connection, adapt to the down-hole and install and use condition;

2, a side of support has two root posts, is connected in same back timber and the base, and the ability of its opposing lateral load is increased greatly;

3, base contacts with cylinder body and fixes by the rubber ring that resets, and after support suffers strong lateral pressure and a small amount of distortion takes place, can recover original form voluntarily;

4, the needling in 4 root posts and back timber and the base is a plane contact, strengthens the stability of support when bearing top pressure and surge greatly;

5, the column cavity of resorption all is provided with big flow double safety valve, when instantaneous load meets or exceeds the column safety margins, can slow down the column internal pressure in moment, avoids the generation of device damage and security incident;

6, support can be failure to actuate for a long time, so Hydraulic Elements have the anti-corrosion characteristics, valve member all has chromium coating inside and outside being stainless steel, column;

7, lower transverse beam can prevent the tunnel pucking that causes because of bump.

Fig. 1 is a front view of the present utility model.

Fig. 2 is a lateral view of the present utility model.

Fig. 3 is that of the present utility model overlooking partly cutd open figure.

The specific embodiment:

Embodiment:

With reference to Fig. 1-3, this protecting against shock brettis comprises top rail 1, lower transverse beam 2 and big flow stainless steel double safety valve 7, it also comprises back timber 3, base 4 and column 8, the two ends of above-mentioned top rail 1 are connected by bearing pin with the back timber 3 of two heel posts, 8 tops respectively, back timber 3 links to each other with column 8 piston rods, column 8 cylinder bottom seats are in base 4, and two wing bases 4 and lower transverse beam 2 link to each other by bearing pin, and the cylinder body of column 8 is provided with big flow stainless steel double safety valve 7.

Be welded with two flat needlings and the ear seat that is connected with column 8 piston rods in the described back timber 3, an outside side is provided with the ear seat that is connected with top rail.

Described base 4 tops are provided with the rubber sleeve 5 that resets, and in the rubber sleeve 5 that resets the rubber of resetting 6 are arranged; Base 4 bottoms are welded with two flat needlings.

The cylinder bottom of described column 8 and piston rod column cap are the plane, on the piston rod column cap pin-and-hole are arranged, and cylinder body is provided with big flow stainless steel double safety valve 7.

Operating principle of the present utility model:

After each parts of protecting against shock brettis are transported in the tunnel that needs supporting, base 4 and lower transverse beam 2 are connected; With column 8 by on put into base 4 needlings, the locking rubber sleeve 5 that resets; Load onto back timber 3 and top rail 1; Big flow stainless steel double safety valve 7 is connected on column 8 cylinder bodies.

Rise four columns simultaneously, top board that supports the tunnel and base plate that support is firm.Put support along roadway direction with some these supports are adjacent, promptly form firm lane space.
