Description
Technical field
The utility model relates to mining exploitation support apparatus technical fields, more specifically, being related to a kind of coal mine roadway branch
Protection unit.
Background technique
The coal mine in China is mainly underground mining, needs to dig a large amount of tunnels in underground, keeps tunnel unimpeded steady with country rock
It is fixed to be of great significance for construction of coal mine and production, with mining depth and range, the increase of mining rate, geological conditions day
Become to complicating, the complexity item such as high-ground stress tunnel, strong mining influence tunnel, soft and broken surrounding rocks tunnel and extra-large cross-section tunnel
The specific gravity that part accounts for is increasing, increases the difficulty of roadway support, there are security risks by staff in tunnel.
Utility model content
The purpose of the utility model is to provide a kind of coal mine tunnel suspension device, the device is anti-using multilayer inert gas
Revetment carries out supporting to tunnel, and stress force is more uniformly gentle, and supporting effect is preferable, can also monitor pneumatic parameter in real time,
Protect underground work personnel safety.
To achieve the goals above, the technical solution adopted in the utility model is as follows：
A kind of coal mine tunnel suspension device, including bottom fixation steel plate, above the bottom fixation steel plate from the inside to the outside according to
Secondary interior branch sheath, first gas branch sheath, second gas branch sheath, third gas branch sheath and the outer branch sheath for being equipped with annular,
Gas via-hole, and every layer of gas are equipped on the first gas branch sheath, second gas branch sheath and third gas branch sheath
Through-hole aperture is successively reduced, and gas generating unit is equipped with below the first gas branch sheath, is set on the inside of the interior branch sheath
There is a pressure display unit, the pressure display unit is sequentially connected that there are three pressure sensor, three pressure sensings by route
Device is located inside gas with various branch sheath, if being equipped between the bottom fixation steel plate, interior branch sheath and outer branch sheath
Dry fixing anchor bar.
Further, high-pressure inert gas is filled inside the gas generating unit.
Further, the gas branch sheath is all made of high-resistance material and is made.
Further, the interior branch sheath and outer branch sheath two sides are fixed with bottom fixation steel plate.
Wherein inside and outside branch sheath uses different support materials, and it is strong that outer branch jacket material intensity is less than interior branch jacket material
Degree.
Compared with the prior art, the beneficial effects of the utility model are as follows：
The utility model uses three gas branch sheath combination high-pressure inert gas, can form three preventing gas revetments,
Realize supporting operation, gas stress force is more stable average, and supporting effect is more preferable compared with conventional rigid structure, and inert gas can be with
It avoids reacting with impurity in drive and causes security risk；Using structures such as pressure display unit and pressure sensors, may be implemented pair
The dynamic monitoring of each gas branch sheath internal pressure situation notifies underground work when irregular movement occurs for pressure value
Personnel withdraw in time, guarantee staff's personal safety.

In actual use, bottom fixation steel plate is first set, outer branch sheath 7, gas branch are then successively arranged inside tunnel
It is solid to connect interior branch sheath 5, outer branch sheath 7 and bottom by fixing anchor bar 2 for sheath 8 and Nei Zhi sheath 5 and related electric original part
Determine steel plate 1, finally connect gas generating unit 6, high-pressure inert gas is filled to gas branch sheath 8 by gas generating unit 6,
4 registration of pressure display unit is observed, when reaching secure setting, stops aeration.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.This
The technical staff of industry is retouched in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
