Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a deformation monitoring reflector fixing device. Background Technology

[0002] During tunnel construction, it is necessary to monitor the tunnel's deformation status at all times to ensure construction safety. The usual monitoring method involves installing multiple reflectors on the tunnel arch and using a total station to measure the reflectors and monitor changes in the arch height. Currently, the reflectors are installed by adhesive-bonded to steel sheets and secured to the arch using expansion bolts.

[0003] For example, the patent application with authorization announcement number CN215930860U and title "An Installation Structure for a Tunnel Deformation Monitoring Reflector" includes a road spike. The road spike has a rectangular top surface, a bottom surface with an area larger than the top surface, and four trapezoidal sides. Two opposite sides are fluorescent surfaces. A tunnel detection reflector is pasted in the middle of one of the fluorescent surfaces. White reflectors are pasted on the top surface of the road spike and the other two opposite sides. The road spike is installed on the tunnel arch with the top surface of the road spike facing down and the two fluorescent surfaces of the road spike facing the two ends of the tunnel. The two opposite sides or four corners of the road spike are fixed to the tunnel arch by expansion bolts.

[0004] Because the surrounding rock mass of a mine tunnel is in a relaxed state, there may be falling rocks during the tunnel construction process. The vibration of the working machinery during construction may cause friction and collision with surrounding objects. Since the optical reflector installed in one location needs to be measured multiple times at different times, it cannot be removed even when it is not in use. The optical reflector, which is always exposed to the tunnel environment, is at risk of being damaged by flying rocks from blasting or collisions with the working machinery. In addition, damage to the optical reflector will lead to discontinuity in monitoring. Even if a new optical reflector is reinstalled in the same location, it cannot make up for the risk of discontinuity in monitoring data. Therefore, the protection of the optical reflector installed in the tunnel support is particularly important. Utility Model Content

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-4 As shown, this utility model embodiment provides a deformation monitoring reflector fixing device, including a mounting base 1 and a reflector component 2. The mounting base 1 is provided with a mounting structure 11 that can be fixed on the tunnel arch. The mounting base 1 is provided with a mounting opening 12 away from the tunnel surface. The reflector component 2 includes a vertically arranged reflector 21 and a prompting element 22. The reflector 21 and the prompting element 22 are connected to form an L-shaped reflector. A rotating mounting part 23 is formed at the connection between the reflector 21 and the prompting element 22. A rotating shaft 24 is provided at the rotating mounting part 23. A rotating connecting part is provided on the opposite side wall of the mounting opening 12. The two ends of the rotating shaft 24 are rotatably mounted on the rotating connecting part. The reflector component 2 rotates around the rotating shaft 24 to have a monitoring state and a protection state. In the monitoring state, the prompting element 22 is retracted into the mounting opening 12, and the reflector 21 is located outside the mounting opening 12 and perpendicular to the mounting base 1. In the protection state, the reflector 21 is retracted into the mounting opening 12, and the prompting element 22 is located outside the mounting opening 12 and perpendicular to the mounting base 1.

[0029] Specifically, the mounting base 1 can be fixedly installed on the tunnel arch. The mounting base 1 is provided with a mounting structure 11, which can be a mounting screw hole. The mounting base 1 is fixedly installed on the tunnel arch by expansion screws. In order to improve the installation strength between the mounting base 1 and the tunnel arch, the mounting surface of the mounting base 1 corresponding to the tunnel arch can be an arc-shaped surface. The side of the mounting base 1 away from the tunnel arch is provided with a mounting opening 12. The mounting opening 12 is a rectangular opening for the installation of the reflective component 2.

[0030] In this embodiment, the reflective component 2 includes a vertically arranged reflector 21 and a prompting component 22. The reflector 21 cooperates with the total station for monitoring. A rotating mounting part 23 is formed at the connection between the reflector 21 and the prompting component 22. A rotating shaft 24 is provided on the rotating mounting part 23, and the reflective component 2 can rotate around the rotating shaft 24. The reflective component 2 has two working positions when rotating around the rotating shaft 24, which correspond to the monitoring state and the protection state, respectively. When the reflective component 2 rotates to the first working position, which corresponds to the monitoring state, the prompting component 22 is completely retracted into the mounting opening 12. The reflector 21 is located outside the mounting opening 12. At this time, the reflector 21 is perpendicular to the mounting base 1. It can be detected by the total station and the reflector 21 working together. When the reflector 2 rotates to the second working position, it is in the protection state. The reflector 21 is stored inside the mounting opening 12. In this way, the reflector 21 is not exposed, which can protect the reflector 21. The indicator 22 is located outside the mounting opening 12 and perpendicular to the mounting base 1. The indicator 22 can be a sign with an indicator. The material of the sign can be iron, aluminum alloy, etc. The indicator 22 is not easily damaged.

[0031] The deformation monitoring reflector fixing device provided in this embodiment includes a mounting base 1 and a reflector component 2. The mounting base 1 is provided with a mounting structure 11 that can be fixed on the tunnel arch. The mounting base 1 has a mounting opening 12 away from the tunnel surface. The reflector component 2 includes a vertically arranged reflector 21 and a warning component 22. The reflector 21 and the warning component 22 are connected to form an L-shaped reflector. The reflector component 2 is rotatably connected in the mounting opening 12. The reflector component 2 rotates around its rotation axis 24 to have a monitoring state and a protection state. Thus, during the detection process, the reflector component 2 is rotated to the monitoring state, so that the reflector 21 is exposed and cooperates with the total station to achieve detection. When not detecting, the reflector component 2 is rotated to the protection state, at which time the warning component 22 is exposed. The warning component 22 serves as a warning to vehicles and construction personnel. At the same time, the reflector 21 is stored in the mounting opening 12 and protected, making it less likely to be damaged.

[0032] In this embodiment, preferably, a positioning component 3 is also included, which is disposed within the mounting opening 12 and used to fix the reflective member 2 in a monitoring state or a protection state. There are two sets of positioning components 3, which are respectively disposed on opposite sides of the mounting opening 12. The reflective member 21 and the prompting member 22 are provided with positioning structures corresponding to the positioning components 3. Thus, when the reflective member 2 is rotated to the first working position, the positioning components 3 are connected and restricted by the positioning structures on the prompting member 22, thereby locking the reflective member 2 in the first working position (monitoring state). Similarly, when the reflective member 2 is rotated to the second working position, the positioning components 3 are connected and restricted by the positioning structures on the reflective member 21, thereby locking the reflective member 2 in the second working position (protection state).

[0033] In this embodiment, preferably, the positioning component 3 includes a positioning plate 31 fixedly disposed within the mounting opening 12. The positioning plate 31 is provided with a positioning hole 32, and a positioning element is disposed within the positioning hole 32. The positioning hole 32 includes a first segment 33 and a second segment 34 connected together. The radial dimension of the first segment 33 is greater than the radial dimension of the second segment 34. An arc-shaped connecting segment is formed at the connection between the first segment 33 and the second segment 34. The radial dimension of the second segment 34 is greater than the radial dimension of the positioning limiting post 25, so that the positioning limiting post 25 can be inserted into the positioning hole 32 during the rotation of the reflective component 2.

[0034] In this embodiment, preferably, at least two radial opening slots 35 are provided on the side wall of the second segment 34. The positioning element includes a positioning bead 36, which is installed in the radial opening slot 35 through an elastic connector 37. For example, there are three radial opening slots 35, which are arranged sequentially at intervals along the circumference of the positioning hole 32. All three radial opening slots 35 are connected to the second segment 34. The elastic connector 37 is a spring. A sliding piece is integrally provided on the positioning bead 36. The sliding piece is slidably connected in the radial opening slot 35. A connecting post 38 is provided on one side of the sliding piece and the elastic connector 37. The elastic connector 37 is sleeved on the connecting post 38. One end of the elastic connector 37 is connected to the sliding piece, and the other end of the elastic connector 37 is fixedly installed on the inner wall of the radial opening slot 35. When the elastic connector 37 is in its initial state, the positioning bead 36 extends out from the positioning hole 32.

[0035] In this embodiment, preferably, both the reflector 21 and the indicator 22 have positioning limiting posts 25 on their back sides. The positioning limiting posts 25 can be embedded into the positioning holes 32. Each positioning limiting post 25 includes a tapered insertion end 251 and a circumferential arc-shaped groove 252. The circumferential arc-shaped groove 252 corresponds to the positioning bead 36. When the positioning limiting post 25 is inserted into the positioning hole 32, it is inserted into the second segment 34. The tapered insertion end 251 of the positioning limiting post 25 presses against the positioning bead 36, causing the positioning bead 36 to move into the radial opening groove 35 to press against the elastic connector 37. When the reflector 2 rotates to the first working position or the second working position, the circumferential arc-shaped groove 252 corresponds to the positioning bead 36, and the elastic connector 37... The positioning beads 36 are respectively embedded into the circumferential arc-shaped grooves 252. Under the action of the elastic connector 37, the positioning beads 36 position and restrict the positioning limiting post 25, thereby positioning the reflective member 2 in the first working position or the second working position. At the same time, in order to facilitate the switching of the reflective member 2 between the first working position and the second working position, the upper and lower sides of the circumferential arc-shaped grooves 252 are formed with arc edges along the axial direction of the positioning limiting post 25. For example, when the reflective member 2 switches from the first working position to the second working position, the upper arc edge of the circumferential arc-shaped groove 252 presses against the positioning beads 36, causing the positioning beads 36 to be pressed into the radial opening groove 35, thereby allowing the positioning limiting post 25 to be pulled out from the positioning hole 32.

[0036] In this embodiment, preferably, during use, when the reflective component 2 switches between the first working position and the second working position, it can be manually rotated. Alternatively, a rotation drive 4 can be provided, which is disposed within the mounting opening 12. The rotating shaft 24 is driven by the rotation drive 4 to switch between the monitoring state and the protection state. The rotation drive 4 can be a cylinder and a piston rod, with the piston rod connected to the rotating shaft 24. Thus, the operation of the cylinder and the piston rod can drive the reflective component 2 to rotate, thereby switching the reflective component 2 between the first working position and the second working position.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
