Abstract

The invention relates to 360-degree free-of-leveling forced centering collimation equipment and a using method thereof. The 360-degree free-of-leveling forced centering collimation equipment comprises a centering bolt, a forced centering pipe, a guide rod and a small prism, wherein the centering bolt is fixed in a monitoring body, the forced centering pipe and the centering bolt are in screwed connection with each other by internal threads, the guide rod and the lower end of the small prism are in screwed connection with each other through threads, the guide rod is directly inserted into the forced centering pipe and can concentrically rotate but does not shake in the forced centering pipe, a total station is erected at a place with a good sighting condition, and the small prism is manually adjusted to face the total station. A reference point and a monitoring point can be simulantoulsy observed, and after observation, the small prism or the forced centering pipe is dismounted according to practical situations of a project, or before project completion, the equipment stays still. The 360-degree free-of-leveling forced centering collimation equipment has the beneficial effects of carrying out the high-precision repeated centering, being convenient to disassemble and install, being capable of rotating by 360 degrees, having high operation efficiency, and protecting the monitoring point easily.

Description

360 degree are exempted from leveling forced centering sighting means and using method

Technical field

The present invention relates to a kind of in the deformation monitoring field particularly in horizontal displacement monitoring 360 degree as the monitoring point sign exempt from leveling forced centering sighting means and using method.

Background technology

Horizontal displacement monitoring is as the traditional monitoring project in deformation monitoring, because it can directly measure the deflection of monitoring body, always being subject to each side pays close attention to, tradition horizontal displacement monitoring point is mainly the nail of top band " ten " word, if employing angle-measuring method, sighting target is survey pin, this method is subjected to the site condition restriction to use limited, if adopt the total station instrument coordinate method, need each centering leveling prism as sighting target, this sighting target operating efficiency is low, and accuracy of alignment is also low, but this method place is adaptable, uses at present more extensive.At present along with the use of full-automatic total powerstation (robot measurement), the monitoring of high-accuracy high-efficiency rate becomes a reality, a problem appears again in this method in engineering practice, the prism that is fixed on the monitoring body can only be aimed at a direction, and this allows the position of selecting to set up instrument be limited to, and the construction site personnel are complicated, quality just differs, be fixed on that the prism of monitoring on body lost without reason and the phenomenon destroyed is serious, and prism is more expensive equipment, cost increases greatly virtually.

Summary of the invention

based on above these situations, but high precision repeats centering, dismounting and installation are all very convenient, and can arise at the historic moment by 360 sighting means of spending rotation, concrete technical scheme is, a kind of 360 degree are exempted from leveling forced centering sighting means and using method, comprise centring screw bolt, the forced centering pipe, guide pole, little prism, it is characterized in that: described forced centering pipe is the pipe with the internal thread screw thread, forced centering pipe and centring screw bolt adopt the internal thread screwed connection, guide pole is connected with little prism lower end screw thread, guide pole directly inserts in the forced centering pipe, guide pole can be rotated with one heart and do not rock in the forced centering pipe.

Using method is carried out according to the following steps, and 1. centring screw bolt is fixed in the monitoring body, and electricity consumption is drilled on the monitoring body and holes, and hole depth is determined according to centring screw bolt length, inserts centring screw bolt and fixing, and centring screw bolt protrudes the monitoring surface;

2., the forced centering pipe is screwed on the centring screw bolt of protrusion, according to the monitoring point numbering, the forced centering pipe of corresponding numbering is screwed on the centring screw bolt of protrusion, tightness take the forced centering pipe firmly, loosening and with hand, can back out as principle, after installing first the forced centering pipe, draw markings at centring screw bolt on outside or monitoring surface, forced centering pipe with pen, and centring screw bolt is corresponding with the markings on the forced centering pipe, in order to the forced centering pipe is installed to same position at every turn;

3., the reference numeral guide pole is screwed in the screw thread of little prism lower end and inserts in the forced centering pipe, guide pole can be rotated with one heart in the forced centering pipe, guaranteed that the forced centering pipe all can accurately be installed to same position at every turn;

4., observation, set up total powerstation in place preferably at sighting condition, the little prism of manual adjustments, towards total powerstation, can start to observe simultaneously reference point and monitoring point;

5., observation can be unloaded little prism or forced centering pipe according to the engineering actual conditions after complete, or keep motionless before project is completed.

Repeat centering and can rotate by 360 degree but technique effect of the present invention is high precision, dismounting and easy for installation, operating efficiency is high, and monitoring point is easily protected.

Description of drawings

Fig. 1 is structural representation of the present invention.

Embodiment

as shown in Figure 1, be installed to as centring screw bolt 1 on the monitoring body and fixing with the single ended bolt of M12 or with the expand tube bolt of M12 bolt with the instruments such as electric drill punchings on the monitoring body, monitoring body 1 ~ 2cm is exposed at centring screw bolt 1 top, it is that the weldless steel tube of M12 is as forced centering pipe 2 that Precision Machining goes out internal thread, forced centering pipe 2 is threaded with centring screw bolt 1, tightness degree is for mounting and dismounting with hand, after installing first on forced centering pipe 2 and centring screw bolt 1 or monitoring body setting-out serve as a mark, all allow mark aim at later at every turn, guaranteed that forced centering pipe 2 all can accurately be installed to same position at every turn, little prism 4 models can be the little prism of come card GMP111 or the little prism group of imitative come card, guide pole 3 is the straight Metallic rod of TOE, thread size and little prism 4 lower end threaded holes are measure-alike, straight Metallic rod diameter is identical with centering pipe 2 internal diameters, only need during use forced centering pipe 2 and centring screw bolt 1 are threaded onto mark, guide pole 3 is together with little prism 4 is screwed onto, guide pole 3 inserts in forced centering pipe 2 and gets final product.

During observation, at sighting condition, set up total powerstation in place preferably, the little prism 4 of manual adjustments is towards total powerstation, can start to observe simultaneously reference point and monitoring point, observe after complete and can unload little prism 4 or forced centering pipe 2 according to the engineering actual conditions, or keep motionless before project is completed.
