Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-7 is please referred to, the utility model provides a kind of technical solution: a kind of protection and police of tunnel safety monitoring measuring point The top of showing device, including fixed link 4, fixed link 4 is fixedly connected with protecting box 5, the surrounding outside of protecting box 5 by screw 3 Equipped with reflective membrane 6, reflective membrane 6 constitutes fixed structure by glue bonding mode and protecting box 5, this structure makes protecting box 5 exist It is more obvious when being irradiated to by light, resolution of the staff to monitoring stations of being more convenient for, so as to effectively prevent machinery to set Standby operator because can not it is clear that due to monitoring stations are damaged the problem of, protecting box 5 is rectangular parallelepiped structure, and protecting box 5 is rectangular Front side edge, back side edge and the left side of body structure pass through shaft and bottom edge constitutes rotational structure, this structure can be by small prism 1 It blocks completely, so as to form full protection to monitoring stations, reaches and protect monitoring stations portion not by whitewashing, slungshot and dust Etc. the effect being stained, and the rotational structure, the staff that is more convenient for open protecting box 5, small rib when guaranteeing monitoring measurement 1 measurement request of mirror, fixed link 4 is two-part structure, and the upper section of the two-part structure and lower section are connected by adjusting bolt 10, This structure makes the device after mounting, is able to carry out certain angular adjustment, so that the staff that is more convenient for is to monitoring stations Installation, and the settable screw thread in bottom of the fixed link 4 makes the more stable jail when being fit into concrete of fixed link 4 Gu 5 left side top of protecting box is fixedly connected with the raised line 9 that bottom is spill, and the inside grooves of 5 top left side of protecting box are embedded There are compressed spring 8 and ball 7, ball 7 constitutes elastic construction by the upper side edge of 5 rectangular parallelepiped structure of compressed spring 8 and protecting box, And front side edge, back side edge and the left side of 5 rectangular parallelepiped structure of protecting box pass through 5 rectangular parallelepiped structure of the elastic construction and protecting box Top constitute movable buckle structure, this structure not only makes the opening of protecting box 5 more convenient, and makes closing for protecting box 5 Closing operation is equally convenient, to be more convenient for using the top horizontal of fixed link 4 is rotatably connected to small prism support 2, and small prism The top of support 2, which longitudinally rotates, is connected with small prism 1.

Working principle: in protection and the alarming device for using the tunnel safety monitoring measuring point, whether the device is first checked The case where there are part breakage or being not connected firmly carries out after inspection is errorless again using then staff is preparatory using impact drill Drilled out in the concrete at the positions such as vault, haunch or abutment wall with 4 diameter of fixed link hole of corresponding size, then by fixed link 4 Bottom end be inserted into the hole, so that fixed link 4 and hole is agreed with fixation, fixed link 4 is two-part structure, and 4 two sections of fixed link The upper section and lower section of formula structure constitute rotational structure by adjusting bolt 10, can be right with this configuration by 4 rotation bending of fixed link The position angle of small prism 1 is adjusted, and after adjusting, rotation, which is tightened, adjusts bolt 10, and fixed link 4 can be made to keep solid It is fixed, the installation of the device is completed, when needing to measure the monitoring stations, it is rectangular that staff holds protecting box 5 Raised line 9 is pulled to the outside of protecting box 5, makes the front side edge of 5 rectangular parallelepiped structure of protecting box with after by the raised line 9 on the outside of body structure Side is successively opened, at this point, small prism 1 loses the front side edge of 5 rectangular parallelepiped structure of protecting box and blocking for back side edge, staff Normally the monitoring stations can be measured, it is preceding during staff pulls open 5 front side edge of protecting box and back side edge Side and back side edge can push up upwards ball 7, move up ball 7, compressed spring 8 is allowed to shrink, due to compressed spring 8 Elastic force be much smaller than staff arm strength so that staff can be easily by the front side of 5 rectangular parallelepiped structure of protecting box Side and back side edge are pulled open, and after the front side edge of 5 rectangular parallelepiped structure of protecting box and back side edge are pulled open, the diameter of ball 7 due to Less than the diameter of 5 rectangular parallelepiped structure upper side edge bottom opening of protecting box, will not fall, it, will when not needing use device The front side edge and back side edge of 5 rectangular parallelepiped structure of protecting box of expansion push up, and front side edge and back side edge is made to turn to vertical configuration State, then ball 7 sticks into the groove structure at the top of front side edge and back side edge, can make the front side of 5 rectangular parallelepiped structure of protecting box Side and back side edge are kept fixed, at this point, the rectangular parallelepiped structure of protecting box 5 forms blocking to small prism 1 comprehensively, reach protection prison The effect that control measuring point portion is not stained by whitewashing, slungshot and dust etc., the illumination light irradiation of other mechanical equipments when constructing tunnel When in protecting box 5, reflective membrane 6 is to the reflecting effect of light, so that protecting box 5 is more obvious, the staff that is more convenient for is to prison Control measuring point resolution, so as to effectively prevent mechanical equipment operator because can not it is clear that due to by monitoring stations damage asking Topic, here it is the protection of the tunnel safety monitoring measuring point and the working principles of alarming device.

Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all It is included within the scope of protection of this utility model.
