Description
Technical field
The utility model relates to a kind of can, refers in particular to a kind of tunnel deformation survey mark reflectance coating protection box.
Background technology
Tunnel Engineering, especially large tunnel, complicated geology is changeable, and difficulty of construction is bigger.Real-time monitored is carried out in surrouding rock deformation, is to guarantee construction safety, definite indispensable work of tunnel support rationally.The most advanced at present observation procedure is the non-contact measurement method, promptly at first reflectance coating is pasted the observation station of tunnel buttress, adopts total powerstation by laser or infrared light it to be observed then.If reflectance coating is directly sticked on the country rock in tunnel, because the working-yard environment is abominable, dust, sandstone or grout can block reflection or destroy very soon, so that measure and can't continue.In existing surveying work, people need a kind of reflectance coating protective device easy to use.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of unlatching and closure tunnel deformation survey mark reflection protection box easily, and this protection box can effectively prevent the infringement of dust to reflection, and sturdy and durable, easy to use, impact resistance is strong.
The utility model is that the technical scheme that its technical matters of solution is adopted is: a kind of tunnel deformation survey mark reflectance coating protection box comprises box body 2, lid 3, pedestal 4, torsion spring 5, spring post 6 and torsion spring card 7.Box body 2 is to extend upper and lower side and left and right side is constituted by box surface, and lid 3 is to extend upper side edge and left and right side is constituted by the lid surface.One end of pedestal 1 is provided with two above mounting holes, the outside surface of the other end and box body 2 fixes, the bottom of box body 2 and lid 3 inside surfaces is provided with torsion spring card 7, spring post 6 is coupling box body 2 and lid 3 in the bottom of left and right side, torsion spring 5 is socketed on the spring post 6, the leading foot at torsion spring 5 two ends is connected to respectively on the torsion spring card 7 of box body 2 and lid 3, and lid 3 upwards is closing direction, and a reflection 1 pastes on the inside surface of box body 2.
The inside surface of box body 2 upper side edges is fixed with a strong magnets 8.
The upper end of lid 3 outside surfaces is fixed with a draw ring 9.
Offer a breach greater than torsion spring steel wire external diameter at box body 2 lower sides and the corresponding position of torsion spring 5 length.
The beneficial effects of the utility model are:
1, rational in infrastructure: as, to make its closure fast, effective owing to adopt torsion spring and strong magnets between box body and the lid as the power assisting device of closure.Again owing to offer torsion spring steel wire breach at the lower side of box body, and lid do not set side, in the time of can guaranteeing that the downward opening angle of lid surpasses 90 °, can not stop mutually between lid and box body and the torsion spring.
2, easy to use: owing to when opening the protection box, take pull-down pattern; and lie on the stay cord with weights such as stones; can make lid be in open mode easily finishes up to measurement; and when closure protection box; relied on the elastic force of torsion spring before this; after again by the suction of magnet, lid is turned over to closure on can be fast.
3, protection is effective: because its closure is good, can effectively prevent the infringement to reflection of working-yard dust, sandstone and grout.
4, sturdy and durable: because the protection box adopts the iron plate with impact resistance to make, and by screw retention on the metal connecting piece that buries system in advance, do not have consumable accessory, but shock resistance after the plastic-blasting protection against the tide, corrosion-resistant.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe in further detail.
As Fig. 1, Fig. 2, tunnel deformation survey mark reflection protection box shown in Figure 3, comprise box body 2, lid 3, pedestal 4, torsion spring 5, spring post 6 and torsion spring card 7.Box body 2 is to extend upper and lower side and left and right side is constituted by box surface, and lid 3 is to extend upper side edge and left and right side is constituted by the lid surface.Box body 2 and lid 3 are made by the thick steel plate of 2mm, make it have stronger impact resistance.Pedestal 1 is made by angle steel, and a side of angle steel is provided with two mounting holes, and fixes by this mounting hole and the metal connecting piece that is secured on the tunnel-side, and the another side of angle steel fixes by the outside surface of 4 screws and box body 2.The bottom of box body 2 and lid 3 inside surfaces is welded with torsion spring card 7, spring post 6 is coupling box body 2 and lid 3 in the bottom of left and right side, torsion spring 5 is socketed on the spring post 6, the leading foot at torsion spring 5 two ends is connected to respectively on the torsion spring card 7 of box body 2 and lid 3, rely on the elastic force of torsion spring, can make lid 3 overcome gravity and the closure that makes progress, or open downwards by pulling force.But the reflectance coating 1 of reflected light signal pastes on the inside surface of box body 2, and the laser or the infrared signal that send by the reflection total powerstation are the deformation measurement that total powerstation is finished the measured point.
As shown in Figure 3, be fixed with a strong magnets 8 on the interior table of box body 2 upper side edges, utilize its attractive force to metal, the closing motion that upwards rebounds for lid provides power-assisted.
As Fig. 1, shown in Figure 4, be fixed with a draw ring 9 in the upper end of lid 3 outside surfaces, hanging has a stay cord 10 on the draw ring 9, and the length of stay cord depends on the height that the protection box is fixed, and the surveyor may stand in the open and close of terrestrial operation protection box.
As Fig. 2, shown in Figure 3, offer a breach greater than torsion spring steel wire external diameter at box body 2 lower sides and the corresponding position of torsion spring 5 length, its objective is that the leading foot of torsion spring 5 can not stopped by the lower side of box body 2 when lid 3 downward angles of opening were worked as in assurance above 90 °.
As Fig. 2, shown in Figure 5, the short side thereon of height of box body 2 lower sides and the height of left and right side, the discrepancy in elevation of left and right side and lower side is circular arc, its objective is that lid 3 can not stopped by the lower side of box body 2 when lid 3 downward angles of opening were worked as in assurance above 90 °.
When using the utility model; the protection box that will post reflectance coating 1 earlier is fixed on the metal connecting piece of tunnel-side by its pedestal; when needs are reflected into total powerstation cremasteric reflex luminous point; spur stay cord 10 downwards; and pass through draw ring 9 lid 3 is opened 180 ° downwards; at the lower end of stay cord 10 bolt one weight, make lid 3 be in normally open then.When measurement finishes, unclamp stay cord 10, under the effect of torsion spring 5, lid 3 upwards turns over and closes, and along with turning over the increasing of closing angle, the elastic force of torsion spring is more and more littler, the attractive force of 8 pairs of lids 3 of strong magnets of being located at box body 2 tops this moment is then increasing, finally causes lid 3 and box body 2 closed fully.After lid 3 and the box body 2 complete closures, can prevent the intrusion of dust, with the precision of guaranteeing to measure; Can stop the impact of sandstone, with the long-term use of guaranteeing to reflect to reflection.
