Abstract
The utility model provides an anti-collapse device for tunnel support joint shield, comprising a guard support block, an E-shaped wedge steel pipe and racks. The utility model is characterized in that the steel pipe is fixed on the guard support block, the guard support block is clamp on the racks, the E-shaped wedge is fixedly clamp among the guard support block, the steel pipe and the racks, so the steel pipe and the racks can be fastened together. The utility model has the characteristics of reasonable design, simple structure, easy manufacturing, small size, convenient operation, strong safety, etc.
Description
The utility model relates to a kind of mine laneway security hardening equipment, specifically a kind of excavation support connection canopy reversion prevention apparatus.
After roadway excavation in the mine becomes will with protect support with the top in tunnel and both sides support reinforcement in case collapse in the beach in tunnel and roof fall causes stop work and production and casualties, but existing roadway support technology can only support the pressure at right angle from the top, tunnel, but can not bear level and oblique pressure from the top, tunnel, once make top, tunnel generation level or oblique pressure in the vibration of blowing out or being caused by other reasons, top, tunnel and both sides supporting are then taken advantage of a situation and are tilted to cause the beach, tunnel to collapse.In the use of mine laneway, topple over to make the roof fall of collapsing of beach, tunnel because of supporting connection canopy, cause mine stop work and production and personnel casualty accidents to happen occasionally, also there is not good technology and equipment can solve clear tilt of roadway support at present and the problem that causes the beach, tunnel to collapse.
The purpose of this utility model provides a kind of excavation support connection canopy reversion prevention apparatus.
The purpose of this utility model realizes in the following manner, with steel pipe be through the band groove and protect in the bracer, the groove that protects bracer is stuck on the both sides of both sides, tunnel as the track floor of supporting support, insert between steel pipe and the track with E shape drift then, steel pipe is fastened on the track, and the steel pipe level is fixed together the supporting support track of both sides, tunnel by protecting the bracer connection, form an overall structure, thereby can avoid the inclination of bracing frame, prevent that the roof fall in tunnel and beach from collapsing.
Accompanying drawing 1 is the structural representation of facing of excavation support connection canopy reversion prevention apparatus;
Accompanying drawing 2 is the side-looking structural representation of excavation support connection canopy reversion prevention apparatus;
Accompanying drawing 3 is the plan structure schematic diagram of excavation support connection canopy reversion prevention apparatus;
Accompanying drawing 4 is the structural representation of looking up of excavation support connection canopy reversion prevention apparatus.
Below with reference to Figure of description tunnel of the present utility model support connection canopy reversion prevention apparatus being done in detail Explanation.
Tunnel of the present utility model support connection canopy reversion prevention apparatus, its structure is by care-supporting piece 3, E shape wedge Iron 4 steel pipes 2 and track 1 consist of, and steel pipe 2 is fixed on the care-supporting piece 3, and care-supporting piece 3 is stuck on the track 1, E shape drift 4 fixes between care-supporting piece 3, steel pipe 2 and track 1, and steel pipe 2 and track 1 are fastened on Together.
Be provided with circular hole in the middle of protecting bracer 3, steel pipe 2 is through among the circular hole, is positioned at the two ends of protecting bracer 3 to be provided with recessed inwards being used on the tangent line of circular hole and to tighten the fixedly groove 5 of track 1 and E shape drift 4.
E shape drift 4 is provided with twice gap 6, and the both sides of gap 6 are stuck among the groove 5 that protects bracer 3 with the both sides of track 1 base plate.
Embodiment:
Its processing and fabricating of excavation support connection canopy reversion prevention apparatus of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.Protect bracer, E shape drift is a steel-casting, steel pipe is common steel tube or round steel.Using method is also easily simple, concrete operations are as follows: will protect bracer and be through on the steel pipe, be erected at and block one on the both sides as every road orbiting end plate of supporting support of both sides, tunnel and protect bracer, (respectively block one as the both sides that closely are arranged in many tracks of arranging and protect bracer), then with in the slit between E shape spline reeve track and the steel pipe, urgent with tup, steel pipe and track just tightly connect and are fixed together by protecting bracer and E shape drift like this, form whole net structure, be applied in the supporting support if any top, tunnel generation horizontal force or oblique pressure, supporting support the horizontal support of steel pipe is fixing down can run-off the straight, thereby can prevent effectively that the beach in tunnel from collapsing and roof fall.
Tunnel of the present utility model support connection canopy reversion prevention apparatus is compared with existing technology, have reasonable in design, Simple in structure, be easy to processing, the characteristics such as little, the esy to use, safe and reliable property of volume is strong, thereby, Have good value for applications.
Except the described technology feature of specification, be the known technology of those skilled in the art.
Claims (3)
1. excavation support connection canopy reversion prevention apparatus comprises and protects bracer, E shape drift steel pipe and track, it is characterized in that steel pipe is fixed on to protect on the bracer, protects bracer and is stuck on the track, and E shape drift fixes protecting between bracer, steel pipe and the track, and steel pipe and track are tightened together.
2. excavation support connection canopy reversion prevention apparatus according to claim 1, be provided with circular hole in the middle of it is characterized in that protecting bracer, steel pipe is through among the circular hole, is positioned at the two ends of protecting bracer to be provided with recessed inwards being used on the tangent line of circular hole and to tighten the fixedly groove of track and E shape drift.
