Abstract
The utility model discloses a subway and tunnel measuring instrument fixing rack which is formed by two supports of a measuring instrument fixing rack. The front end of the supports is provided with a platform. The center of the platform is provided with a measuring instrument mounting hole. The back end of the two supports is provided with a support fixing plate which is provided with fixed screw holes. Fixed screws can pass through the fixed screw holes to fix the supports on an arc-shaped wall. Two inclined supporting frames are arranged under the supports. Two ends of each of the inclined supporting frames are provided with adjusting threads. One end of each of the inclined supporting frames is connected with a rotating shaft arranged in an adjusting screw hole under the supports, and the other end of each of the inclined supporting frames is connected with an inclined supporting frame fixed plate. The inclined supporting frame fixed plate is provided with an inclined supporting frame fixed plate screw hole which can be fixed on the arc-shaped wall by a screw. The subway and tunnel measuring instrument fixing rack is suitable for the measurement in a subway and a tunnel in construction.
Description
Technical field
The utility model relates to a kind of fixed mount of surveying instrument, especially relates to a kind of subway, 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, subway easy to use, tunnel survey instrument fixed mount 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 two supports of measuring instrument fixed mount, the front end of support is provided with platform, the center of platform is provided with the measuring instrument mounting hole, the rear end of two supports is provided 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 support, also be provided with two tiltedly holder bearing supports, tiltedly two ends of holder bearing support are provided with the adjusting screw thread, tiltedly an end of holder bearing support is connected at the interior rotation axis of adjusting screw of support below, the other end connects tiltedly holder bearing support fixed head, tiltedly holder bearing support fixed head is provided with oblique holder bearing support 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.(2) easy to use.The utility model adopts remaining 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.
