Abstract
The utility model discloses an automatically measuring device based on laser ranging for measuring the tail gap of a shield machine. The automatically measuring device comprises at least three laser ranging sensors, a communication distribution box and a computer for data processing and displaying, wherein the least three laser ranging sensors are uniformly and annularly arranged in the rear side of a segment erector in the tail of the shield machine, and no shielding object is arranged between the laser ranging sensors and the tail. The automatically measuring device measures the distance to the tail and to the segment through laser ranging sensors, and the tail gap is calculated by the computer. The tail gap is automatically measured on a real-time basis.
Description
Technical field
The utility model belongs to laser measuring device for measuring, is specifically related to a kind of shield machine shield tail gap self-operated measuring unit based on laser ranging.
Background technology
At present, in the shield construction process, mainly by manual type, this metering system has various drawbacks in the measurement in shield tail gap: the first, and the height of staff's technology influences the accuracy of measurement result; The second, manual measurement efficient is lower, and it is very difficult especially manually to carry out shield tail clearance measurement for large-diameter shield; The 3rd, there is potential safety hazard in on-the-spot manual measurement.It is untimely below what time to cause in the shield machine construction process shield tail gap to be adjusted, and has a strong impact on construction speed and construction quality.
Proposed the shield machine shield tail gap self-operated measuring unit based on vision-based detection among the patent CN202066485U, utilized the CCD camera to take the picture that comprises shield tail gap, the relative distance of analyzing each parts in the picture by Computer Vision Detection calculates shield tail gap.The shortcoming of this mode is that use relies on the extraction effect of picture fully, is difficult to the good picture of shooting effect under some state, causes shield tail gap data precision not enough or be difficult to obtain.
The utility model content
Technical problem to be solved in the utility model provides a kind of shield machine shield tail gap self-operated measuring unit based on laser ranging, to realize real-time, the measurement automatically in shield machine shield tail gap.
Realize that the technical scheme that the utility model purpose adopts is:
The shield machine shield tail gap self-operated measuring unit that the utility model provides based on laser ranging, the computing machine that comprises at least 3 laser range sensors, communicates by letter panel box and carry out the data processing demonstration; Described laser range sensor circularizes the rear side that is evenly distributed on the duct piece assembling machine that is positioned at the shield machine shield tail, and guaranteeing does not simultaneously have shelter between laser range sensor and the shield tail.
The utility model device can utilize laser range sensor to record distance with shield tail and section of jurisdiction respectively, goes out shield tail gap by COMPUTER CALCULATION, realize shield tail gap in real time, automatic measurement.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a system architecture synoptic diagram of the present utility model.
Fig. 2 is the scheme of installation of laser range sensor in the utility model.
Fig. 3 is a working state schematic representation of the present utility model.
Among the figure: 1, laser range sensor, 2, the communication panel box, 3, computing machine, 4, duct piece assembling machine, 5, the shield tail, 6, the section of jurisdiction, 7, bracing frame, 8, bolt.
Embodiment
Referring to Fig. 1, Fig. 2, be fixed with duct piece assembling machine 4 by bracing frame 7 in the shield machine.The shield machine shield tail gap self-operated measuring unit based on laser ranging that the utility model provides is arranged in the shield machine, comprises 6 laser range sensors 1 such as (or 3 or 4), communication panel box 2 and carries out the computing machine 3 that data processing shows; Wherein laser range sensor 1 circularizes the rear side that is evenly distributed on the duct piece assembling machine 4 that is positioned at shield machine shield tail 5, and laser range sensor 1 is fixing by bolt 8, and guaranteeing does not simultaneously have shelter between laser range sensor 1 and the shield tail 5; Computing machine 3 is fixed in the shield machine pulpit, and communication panel box 2 is fixed on (not shown) on the walking bridge.
Principle of work:
In the shield machine construction process, can measure shield tail gap by laser range sensor 1 at any time.Be specifically described below in conjunction with 3 pairs of principle of work of the present utility model of accompanying drawing, with laser range sensor 1 workflow is example explanation measuring process: at first, by the laser range sensor 1 emission laser that is installed on the duct piece assembling machine 4 laser spots is beaten on shield tail 5, measure laser range sensor 1 to shield tail 5 apart from t1; Mobile again duct piece assembling machine 4 is beaten laser spots on section of jurisdiction 6 by laser range sensor 1 to Fig. 3 dotted line position, measure laser range sensor 1 to the section of jurisdiction 6 apart from t2; Two groups by recording apart from t1, t2, calculates in conjunction with section of jurisdiction thickness t 3, just can obtain the shield tail clearance delta t=t1-t2-t3 between shield tail 5 and the section of jurisdiction 6.
Calculate the shield tail clearance delta t of 6 positions by 6 uniform laser range sensors 1, computing machine 3 can obtain the orientation of 6 centers, section of jurisdiction with respect to shield tail 5 centers in conjunction with the installation site of laser range sensor 1, realizes the real-time automatic measuring in shield tail gap.The workmen according to measurement result and guidance system deviation ratio, determine next endless tube sheet the correction scheme, pipe sheet assembling is adjusted accordingly.
