Description
Technical field
The utility model relates to hole sealing technology field, relates in particular to a kind of Grouting hole sealing device.
Background technology
At present, along with the increase of the coal mining degree of depth, roadway surrounding rock stress increases, and lithology is variation gradually, and the effect of slurry injection technique in Soft Rock Drifts At Coal supporting is more and more obvious.The quality of sealing of hole effect has affected slip casting effect to a great extent.Existing hole sealing technology mainly contains two kinds: 1. adopt cotton yarn, rapid setting cement or the simple and easy sealing of hole of timber wedge, this kind of sealing of hole mode is simple to operate, and cost is low, but sealing of hole effect is poor; 2. adopt hole packer sealing of hole, this kind of sealing of hole mode is simple to operate, and sealing of hole is effective, but cost is higher.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of sealing of hole rifle.
The technical solution of the utility model is:
A kind of hand-held pneumatic sealing of hole rifle, comprise gun barrel, be arranged on gun barrel front end front back-up ring, be arranged on gun barrel rear end rear back-up ring, be arranged on the rifle termination of front back-up ring front end, described gun barrel below is provided with handle, on described handle, be provided with trigger, trigger and inlet suction port, described rear back-up ring rear end is provided with spring and speed governing knob, between described rear back-up ring and handle, is provided with tracheae.
Further, described rifle termination comprises the copper screw thread straight joint, connector, the headkerchief that connect successively, described headkerchief is connected with gun barrel, copper screw thread straight joint and connector coupling part are wound around unsintered tape, connector and headkerchief coupling part are provided with an O type circle, and headkerchief and gun barrel coupling part are provided with the 2nd O type circle.
Further, described seal head comprises seal head body, is arranged on the y-type seal ring on seal head body.
Compared with prior art, operation is simple for the utility model, and sealing of hole is with low cost, and sealing of hole effect is better.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, 2, 3, a kind of hand-held pneumatic sealing of hole rifle, comprise gun barrel 2, be arranged on gun barrel front end front back-up ring 1, be arranged on gun barrel 2 rear ends rear back-up ring 3, be arranged on the rifle termination of front back-up ring 1 front end, described gun barrel 2 belows are provided with handle 6, on described handle 6, be provided with trigger 9, trigger 8 and inlet suction port 7, described rear back-up ring 3 rear ends are provided with spring 10 and speed governing knob 4, between described rear back-up ring 3 and handle 6, are provided with tracheae 5; Described rifle termination comprises the copper screw thread straight joint 11, connector 12, the headkerchief 13 that connect successively, described headkerchief 13 is connected with gun barrel 2, copper screw thread straight joint 11 and connector 12 coupling parts are wound around unsintered tape, connector 12 and headkerchief 13 coupling parts are provided with an O type circle 15, and headkerchief 13 and gun barrel 2 coupling parts are provided with the 2nd O type circle 16; Described seal head comprises seal head body, is arranged on the y-type seal ring 14 on seal head body.
While adopting described hand-held pneumatic sealing of hole rifle upside-down mounting injecting paste material, turn on front back-up ring 1, take off rifle termination, seal head is pushed into rear back-up ring 3 positions with waddy, injecting paste material is poured into after gun barrel 2, put rifle termination and tighten front back-up ring 1.When sealing of hole, connect wind regime, pull trigger 9 and start injection hole sealing.
As shown in Figure 4, choice for use 1+1 rib fabric (flat rib fabric) is made hole sealing bag 18, and hole sealing bag 18 does not seal straight-tube shape for two ends, leaves the charging aperture 181 that can fill in slip casting flexible pipe 20 on bag; Described hole sealing bag 18 need to be tightened with band 19 with Grouting Pipe.
The first step, is set on hole sealing bag 18 in Grouting Pipe 21, with band 19, hole sealing bag 18 two ends and Grouting Pipe 21 bindings is tightened, and hole sealing bag 18 does not allow at Grouting Pipe 21 surface slidings, and hole sealing bag 18 and Grouting Pipe 21 are connected as a single entity; Second step, inserts slip casting flexible pipe 20 charging aperture 181 of hole sealing bag 18, and tightens with band 19; The 3rd step is sent into Grouting Pipe 21 set depth of boring together with hole sealing bag 18; The 4th step, pours sealing material in the gun barrel 2 of hand-held pneumatic sealing of hole rifle, puts rifle termination and tightens after front back-up ring 1, connects slip casting flexible pipe 20 and pulls trigger 8 and carry out sealing of hole; The 5th step, pulls up slip casting flexible pipe 20 after sealing of hole finishes, and cleans hand-held pneumatic sealing of hole rifle, in order to using next time.
