Abstract
The utility model discloses a tunnel measuring instrument fixing rack, composed of a plane chassis support of the measuring instrument fixing rack. The front end of the plane chassis support is equipped with a plane chassis on which a platform is arranged, and a measuring instrument joint screw is arranged in the center of the platform; the rear end of the plane chassis support is equipped with a support fixing plate and is connected with the fixing plate via a movable shaft, the support fixing plate is equipped with a fixing screw hole through which a fixing screw can penetrate to fix the support on a circular-arc wall; an obliquely-supporting bearing rod is also arranged below the plane chassis support, one end of the obliquely-supporting bearing rod is equipped with an adjusting thread rod and is connected with an adjusting rotating shaft arranged below the plane chassis support, and the other end is connected with an obliquely-supporting bearing rod fixing plate via a movable shaft; the obliquely-supporting bearing rod fixing plate is equipped with a obliquely-supporting bearing rod fixing plate screw hole through which a screw can penetrate to fix the obliquely-supporting bearing rod on the circular-arc wall. The tunnel measuring instrument fixing rack of the utility model is suitable for the measurements and uses of the subways and tunnels under construction.
Description
Technical field
The utility model relates to a kind of fixed mount of surveying instrument, especially relates to a kind of tunnel survey instrument fixed mount.
Background technology
Because of the needs of transport development, build subway, open tunnel is that urban construction has Important Project, and because the tunnel adopts the shield machine operation, progress is fast, and surveying work must in time be caught up with, and the method that traditional employing tripod is measured can't satisfy to build needs.Because the tunnel adopts two wall circular arc types to advance, tunnel survey instrument fixed mount must be fixed on the circular arc type circular arc type metope again.
Summary of the invention
The purpose of this utility model is to provide a kind of design science reasonable, tunnel survey instrument fixed mount easy to use for above-mentioned subway, the existing problem of tunnel survey instrument fixed mount.
In order to achieve the above object, the utility model is mainly finished by the following technical solutions.The utility model mainly is comprised of a rhizoplane chassis overhang of measuring instrument fixed mount, the front end of plane bottom plate support is provided with plane bottom plate, plane bottom plate is provided with platform, be provided with measuring instrument at the center of platform and connect screw, the rear end of plane bottom plate support is provided with bracket fixing plate, the rear end of plane bottom plate support is connected with movable axis with bracket fixing plate, bracket fixing plate is provided with fixed screw holes, fixed screw can pass fixed screw holes support is fixed on the circular arc type wall, below the plane bottom plate support, also be provided with a tiltedly holder cramp bar, tiltedly an end of holder cramp bar is provided with the adjusting threaded rod, tiltedly an end of holder bearing support is connected at the regulating rotary moving axis of plane bottom plate support below, the other end connects tiltedly holder cramp bar fixed head by movable axis, tiltedly holder cramp bar fixed head is provided with oblique holder cramp bar fixed head screw hole, and available screw is fixed on the circular arc type wall.
The utility model compared with prior art has following obvious advantage and progress.(1) simple in structure.Because the utility model scope of application is only limited to subway, tunnel survey, is limited to the tunnel in hole advances, and constantly changes the position, constantly advance, so must be that employing is simple in structure, easy disassembling be easily.The utility model adopts a rhizoplane chassis overhang and an oblique holder cramp bar, at the plane bottom plate support platform is set, and this structure is simple in structure, and is easy for installation, and cost is economized.(2) easy to use.The utility model adopts oblique holder bearing support is set below support, is tiltedly asking bearing support that the adjusting threaded adjusting is set, and degree of regulation is high.
Subway during the utility model is applicable to build, the measurement in tunnel are used.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Accompanying drawing is the utility model one-piece construction and partial cutaway diagram.
