Description
Technical field
The utility model relates to the fixed engineering device technique fields of perforating bullet firing mount, and in particular to a kind of underground mine use perforating bullet
Firing mount fixes device.
Background technique
High-Energy Gas Fracturing Technology is applied to underground coal mine, the low ventilative, weak seam in southern area can be efficiently solved
Coal and gas prominent problem.High-Energy Gas Fracturing Technology in underground coal mine practice process, if perforating bullet firing mount be not fixed or
It is not fixed firmly and leans on, it is most likely that after perforating bullet detonation, cause punching, to substantially reduce the fracturing effect of coal rock layer.
Lined-cavity charge is a kind of high-intensitive high explosive, and lined-cavity charge firing mount is the dress for installing lined-cavity charge
It sets.During field practice, first lined-cavity charge is mounted in firing mount, is sent to the brill accomplished fluently in advance by galvanized pipe afterwards
In hole, and water stemming material and polyurethane sealing of hole agent sealing of hole are used, but influenced by exposed galvanized pipe, drilling can not usually seal reality, together
When perforating bullet ignite after the high temperature and pressure detonation gas that generates act on hole sealing agent, punching accident easily occurs.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the shortcomings of background technique, and it is solid to provide a kind of perforating bullet firing mount
Determine device, improves the sealing quality of drilling, active constraint perforating bullet firing mount, to avoid the generation of punching accident.
The technical issues of in order to solve the utility model, the utility model are achieved through the following technical solutions: a kind of
Underground mine use perforating bullet firing mount fixes device, including fixed block, fixed pallet and anchor pole, described fixed block one end are fixed on institute
It states in fixed pallet, is equipped with and the matched through-hole of galvanized pipe size, the galvanized pipe on perforating bullet firing mount among the fixed block
The through-hole can be passed through；Size and the matched round rockbolt installation of bolt diameter are equably cut into the fixed pallet
Hole, the circle anchor pole mounting hole are equipped with anchor nut, and the anchor pole passes through the round anchor pole mounting hole and anchor nut
It is fixed in the fixed pallet.
Preferably, the fixed block is conical fixed block, and axis of great circle is identical as burst pressure ceasma diameter, axis of small circle
It is identical as zinc-plated pipe diameter, it can be real by water stemming and polyurethane sealing of hole agent plug, it is ensured that sealing quality.
Preferably, the fixed stock material is wood.
Preferably, the anchor pole quantity is at least 2, is symmetrically mounted in the fixed pallet, and it is more firm not only to install,
And active constraint can be provided to perforating bullet firing mount, avoid the generation of punching accident.
Compared with prior art, the beneficial effect that the utility model obtains is:
A kind of fixed device of underground mine use perforating bullet firing mount provided by the utility model uses conical fixed block can be with
It is water stemming and polyurethane sealing of hole agent plug is real, it is ensured that sealing quality.The design of fixed pallet and anchor pole can give perforating bullet bullet
Frame provides active constraint, avoids the generation of punching accident.
The fixed device of a kind of underground mine use perforating bullet firing mount provided by the utility model, keeps burst pressure ceasma sealing of hole tighter
It is real, punching accident occurs after avoiding perforating bullet from detonating, increases explosion fracturing effect.
