The existing airtight wall is single in form, high in potential safety hazard and prone to accidents caused by people being damaged by impact ground pressure and collapse. In response to this problem, the prior art still lacks the necessary safety protection means. Because of high risk and low utilization rate, how to construct security measures on the premise of controlling cost is an urgent problem to be solved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art weak point, provide a simple structure, safe and reliable's an airtight wall body fast-assembling protection device of rock burst mine.
The equipment includes the main part barricade, the main part barricade is used for building in the tunnel of airtight wall inner face, and the airtight wall blocks the opposite of direction promptly, and the accident of collapsing appears if the airtight wall, and the main part barricade can play the effect of sheltering from.
The main part barricade bottom is equipped with the fast-assembling base, equipment such as fast-assembling base accessible stock anchor in tunnel section.
The main part barricade upper portion is articulated to be equipped with first bracing piece, first bracing piece bottom is bent, and its section of bending cavity for anchor assembly such as anchor rod cup joints.
The middle part of the first supporting rod is hinged with a second supporting rod, the tail end of the second supporting rod is bent, a bent section of the second supporting rod is provided with a through groove, and the through groove is used for penetrating anchoring parts such as an anchor rod and fixing the tail end of the second supporting rod on the top surface of a roadway.
Further, the form of establishing the mesh grid in for the frame is erect to the main part barricade, and this kind of form of setting up can guarantee to play sufficient effect of sheltering from when the parapet collapses, shelters from the rubble that splashes. Meanwhile, the weight of the main retaining wall is reduced, the arrangement is convenient, and the manufacturing and assembling cost is saved.
Furthermore, the fast-assembling base is hinged to the bottom of the retaining wall, and the base is respectively arranged at two ends of the bottom of the main retaining wall; a through hole is formed in the fast-assembly base and used for penetrating anchoring pieces such as an anchor rod and the like to fix the bottom of the equipment.
Further, the bottom of the first supporting rod is connected with an anchor rod sleeve in a threaded mode, and the inner sleeve of the anchor rod sleeve is used for sleeving anchoring parts such as an anchor rod. The purpose of this arrangement is to better accommodate the bolt length.
The utility model has the advantages that: the utility model discloses simple structure, the assembly is convenient, and safe in utilization and operation are reliable. Through simple structure, solved the problem that lacks the necessary means of protection to the enclosure among the prior art. The construction cost is considered, meanwhile, the rapid installation of the protective device of the airtight wall is realized, and the protective device plays a considerable positive role in the safety of underground production.

Detailed Description
Referring to fig. 1 and 2, a rock burst mine airtight wall body fast-assembling protection device, including main part barricade 1, main part barricade 1 is used for building in the tunnel of airtight wall inner face, just also the airtight wall blocks the opposite of direction, if the accident of collapsing appears in the airtight wall, main part barricade 1 can play and shelter from the effect.
The main part barricade 1 bottom is equipped with fast-assembling base 2, equipment such as fast-assembling base 2 accessible stock anchor in the tunnel section.
The articulated first bracing piece 5 that is equipped with in 1 upper portion of main part barricade, bend in 5 bottoms of first bracing piece, its section cavity of bending for cup joint anchoring members such as stock.
The middle part of the first support rod 5 is hinged with a second support rod 4, the tail end of the second support rod 4 is bent, a bent section of the second support rod is provided with a through groove, and the through groove is used for penetrating anchoring parts such as an anchor rod and fixing the tail end of the second support rod 4 on the top surface of a roadway.
Further, main part barricade 1 erects the form of netting for the frame in, and this kind of form that sets up can guarantee to play sufficient effect of sheltering from when the parapet collapses, shelters from the rubble that splashes. Meanwhile, the weight of the main retaining wall 1 is reduced, the arrangement is convenient, and the manufacturing and assembling cost is saved.
Furthermore, the fast-assembly base 2 is hinged to the bottom of the retaining wall, and the two bases are respectively arranged at two ends of the bottom of the main retaining wall 1; be equipped with the through-hole in the fast-assembling base 2, the through-hole is used for wearing to establish anchoring members such as stock, and is fixed bottom the equipment.
Further, 5 bottom spiro unions of first bracing piece are equipped with stock sleeve 3, 3 outer walls of stock sleeve are the screw thread form, and its inside sleeve is used for overlapping anchor assembly such as anchor rod.
