At present, when the measuring standard station bracket is erected on the TBM hole top and the shield segment top, the bracket is suspended in the air, a measuring person is inconvenient to mount, dismount, measure and check, and check whether an instrument is inclined or not, meanwhile, a measuring technician is difficult to observe on the bracket, the erecting bracket is tedious in work and time-consuming, and difficult to operate, the measuring instrument is erected on the bracket, the condition that the segment is settled or floats upwards when the shield segment is secondarily injected, the inclination of the measuring instrument is easily caused, and the deviation of measured data is large, so that the data analysis error of a VMT guiding system is caused, the judgment error of TBM and shield machine operators is caused, the propelling section deviates from the design axis, the workload of the measuring person is increased, and the whole construction efficiency is reduced.
Disclosure of Invention
The technical problem to be solved by the utility model is to provide the automatic leveling and fixing device for the TBM trolley measuring instrument, which has a simple structure and is convenient to operate, and can be fixed on the TBM trolley to finish the measurement work of the VMT guide system along with the movement of the trolley.
The technical scheme of the utility model is as follows: an automatic leveling and fixing device for a TBM trolley measuring instrument, comprising: automatic leveling instrument and measurement total powerstation still include: the automatic leveling instrument comprises pedestal legs, a steel plate disc and iron block columns, wherein the bottom of the steel plate disc is fixedly connected with three pedestal legs, the three pedestal legs are in triangular arrangement, the pedestal legs are fixedly connected with a TBM trolley, the top of the steel plate disc is fixedly connected with one ends of the four iron block columns, the other ends of the four iron block columns are fixedly connected with the bottom of the automatic leveling instrument, and the top of the automatic leveling instrument is fixedly connected with a measurement total station.
Further, reinforcing connecting rods are fixedly connected between the three pedestal legs, and inclined supporting plates are fixedly connected to the bottoms of the pedestal legs.
Further, screw holes are formed in the iron block columns.
The utility model has the beneficial effects that: according to the automatic leveling and fixing device for the TBM trolley measuring instrument, the automatic leveling instrument is fixedly connected with the measuring total station, and then the automatic leveling instrument is fixedly connected with the TBM trolley through the steel plate disc, the iron block column and the pedestal legs, so that the automatic leveling instrument and the measuring total station can be fixed on the TBM trolley and move along with the trolley to finish the measurement work of the VMT guide system, the difficulty of the measurement work is reduced, the stability of a measurement reference station is ensured, and the measurement precision of the VMT guide system is improved.
Drawings
In order to more clearly illustrate the embodiments of the present utility model or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described, and it will be obvious to those skilled in the art that other drawings can be obtained according to these drawings without inventive effort.
Fig. 1 is a schematic structural view of an automatic leveling and fixing device of a TBM trolley measuring instrument.
