In order to obtain the data of country rock convergent deformation in constructing tunnel in time, same cross section measuring point generally lays many places, the measuring point hook in the past laid is exposed outside the abutment wall in tunnel greatly, except the engineer operation such as the slag car, forklift equipment is through easily encountering measuring point, and easily pounded by the rubble of avalanche during explosion from the measuring point hook close to face, thus cause measuring point deformation of hook, loosen, even come off.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art; and the tunnel monitoring measurement providing a kind of structure simple, reliable and stable, with low cost convergence measuring point servicing unit; this convergence measuring point servicing unit can available protecting measuring point link, prevents measuring point link by the destruction of the rubble except the engineer operation such as the slag car, forklift equipment or avalanche.
Realizing the technical scheme that the utility model object adopts is, a kind of tunnel monitoring measurement convergence measuring point servicing unit, at least comprise the tapered bur chisel head and embedding fixed bar that are mutually connected, and measuring point link, the end face embedding fixed bar is provided with link protective trough, measuring point link is arranged in link protective trough, the periphery of measuring point link is fixed with link hanger, and measuring point link is articulated with the bottom of link protective trough by link hanger.
Embed the edge protruding formation protruding end tail vertically of fixed bar end face, protruding end tail is the cell wall of link protective trough, and protruding end tail is hinged with protective cover plate.
Protective cover plate by link bolt and protruding end tail hinged.
The periphery of measuring point link is fixed with two link hangers, between two link hangers, is provided with torque spring.
The end face embedding fixed bar is fixed with two link bearings, and two link hangers to snap between two link bearings and hinged with two link bearings respectively.
In above-mentioned tunnel monitoring measurement convergence measuring point servicing unit, measuring point link is hook or link, embeds fixed bar integral fastening in tunnel surrounding abutment wall.
As shown from the above technical solution, the convergence measuring point servicing unit that the utility model provides, embed fixed bar integral fastening in tunnel surrounding abutment wall, the end face embedding fixed bar is provided with link protective trough, measuring point link is articulated with in link protective trough, do not use and measuring point link can be buckled in link protective trough during measuring point link, effectively prevent except avalanche rubble when the destruction of the engineer operation such as the slag car, forklift equipment or explosion is to the destruction of measuring point link.
Hinged protective cover plate on the cell wall of link protective trough and protruding end tail, protective cover plate can to buckle into after in link protective trough protection measurements link from the shock of horizontal avalanche rubble at measuring point link; Protective cover plate by link bolt and protruding end tail hinged, namely the folding of protective cover plate all betides in the plane at protruding end breech face place, according to the actual installation position of convergence measuring point servicing unit, the surfaces of revolution of protective cover plate is parallel with tunnel surrounding abutment wall, therefore restrains when measuring point servicing unit uses and does not take tunnel space.
Measuring point link is articulated with on the end face of embedding fixed bar by hinged link bearing and link hanger, measuring point link can rotate around demarcation line, torque spring is provided with between two link hangers, the two-arm of torque spring is resisted against respectively and embeds on the end face of fixed bar and the edge of measuring point link, by measuring point link automatic spring after protective cover plate is outwarded winding.
As shown from the above technical solution, the convergence measuring point assistant apparatus structure that the utility model provides is simple, reliable and stable, and cost of manufacture is cheap, can effectively prevent measuring point link by the destruction of the rubble except the engineer operation such as the slag car, forklift equipment or avalanche.
