Description
Technical field
The utility model relates to a kind of constructing tunnel template bow member chassis guiding ruler positioner, particularly relates to a kind of constructing tunnel template bow member chassis guiding ruler positioner.
Background technology
Traditional constructing tunnel template bow member trolley mechanism walking or displacement when fixing control, the technological difficulties of constructing tunnel, for the dynamic change error produced after track installation, walking race fixed error, and the balance error that bow member trolley mechanism occurs, bow member trolley running or fixing time, not easily implementation procedure control and control.If in this operation to the control of bow member chassis displacement not in time, can cause in construction operation process, calibration is wasted time and energy, work efficiency is low, and finally causes arch ancient piece of jade, round, flat and with a hole in its centre molding construction difficult quality guarantee.
Utility model content
For above shortcomings in prior art, it is low that the utility model provides a kind of measure cost, be beneficial to constructing tunnel template bow member chassis dynamic or fixing time, constructing tunnel built-up arch rack trolley is carried out to the device of guiding ruler location.
In order to solve the problems of the technologies described above, the utility model have employed following technology:
A kind of constructing tunnel template bow member chassis guiding ruler positioner, described guiding ruler positioner is arranged in tunnel, for the tunneling construction in tunnel; It is characterized in that: in the both sides in tunnel, be symmetrical arranged some piling bars with the centerline parallel in tunneling construction tunnel, and adopt angle steel to be fixedly connected by the piling bar of every side, form constructing tunnel template bow member chassis location guiding ruler; In the two sides of template bow member chassis, installation calibrating contact point respectively, the calibration contact point of both sides is corresponding with the location guiding ruler of this side respectively.
Further feature is: being positioned at the lateral surface of the outermost left and right walking case beam of template bow member chassis, arrange calibration contact point.
The constructing tunnel template bow member chassis location guiding ruler of both sides, tunnel is parallel to each other.
Compared with prior art, the utility model technology tool has the following advantages:
Compared with displacement when 1, walking with traditional constructing tunnel template bow member trolley mechanism or fix controls, for the dynamic change error produced after track installation, walking race fixed error, and the balance error that bow member trolley mechanism occurs, bow member trolley running or fixing time, be easy to process control and control.
2, a kind of constructing tunnel template of this utility model bow member chassis guiding ruler positioner, the walking for bow member chassis dynamic and fixing time location, be easy to observe and control, can work efficiency be improved; Measure cost is low; Implement the technically reliable of overall process.
3, this kind of constructing tunnel template bow member chassis guiding ruler positioner, has great versatility, all can widely use in transportation industry engineering in highway tunnel construction.
Accompanying drawing explanation
Fig. 1, be template bow member chassis guiding ruler positioner elevational schematic view of the present utility model;
Fig. 2 is that Fig. 1 is along A-A to sectional view.
In accompanying drawing: 1-angle steel guiding ruler; 2-fixing piling bar; 3-calibration contact point.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, the utility model template bow member chassis guiding ruler positioner is arranged in tunnel, for the tunneling construction in tunnel, in the direction of advance in tunneling construction tunnel, in the both sides in tunnel, be symmetrical arranged some piling bars 2 with the centerline parallel in tunneling construction tunnel, and adopt angle steel 1 to be connected by the piling bar 2 of every side, form constructing tunnel template bow member chassis location guiding ruler; Be parallel to each other at the location guiding ruler of both sides, tunnel, the tunneling construction direction along tunnel is arranged; Piling bar 2 is firmly arranged on the ground in tunnel, with angle steel 1, piling bar 2 is connected into an entirety, respectively forms the angle steel belt of a certain length in the both sides in tunnel; In the two sides of template bow member chassis, specifically be selected in the lateral surface being positioned at the outermost left and right walking case beam of template bow member chassis, installation calibrating contact point 3 respectively, the calibration contact point 3 of both sides is corresponding with the location guiding ruler of this side respectively, by observing or adjust the gap (distance) between this calibration contact point 3 and location guiding ruler, determine the position of template bow member platform in tunneling construction tunnel.
Implement technological process of the present utility model: < constructing tunnel template in early stage bow member chassis forms operation > → bow member
The parallel position unwrapping wire of the employing → installation guiding ruler of chassis guiding ruler localization method → lay on the symmetrical unwrapping wire position determined piling bar → employing angle steel is fixedly connected after the running job → mono-time operation of installing the calibration contact point → constructing tunnel template bow member chassis guiding ruler location forming location guiding ruler → case beam side of walking about bow member chassis and install completes, template bow member chassis advances → dismantles chassis rear end angle steel, after extension → secondary operation that chassis front preset piling bar is fixedly connected completes, template bow member chassis advance → dismantle chassis rear end angle steel → formation angle steel guiding ruler turnaround cycle use.
The utility model constructing tunnel template bow member chassis guiding ruler positioner, its objective is and improve for the dynamic change error produced after track installation, walking race fixed error, and the balance error that bow member trolley mechanism occurs, bow member trolley running or fixing time, forming process control and control.Play simultaneously to the accurate control of bow member trolley running and fixing time positioning action.The emphasis link of bow member chassis guiding ruler localization method is that the symmetry installation of symmetrical angle steel guiding ruler and the dynamic observation in constructing control.
Above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
