[0002] With the rapid development of the transportation industry, tunnel monitoring and measurement are becoming increasingly common. Tunnel monitoring and measurement is an underground engineering project with complex construction conditions and high risks. Unexpected accidents often lead to personal injury, project delays, and significant economic losses. Therefore, tunnel monitoring and measurement is an indispensable part of tunnel monitoring and measurement and a crucial means to ensure its safety. Current technologies, which use total stations and manual monitoring methods, suffer from limitations such as limited monitoring frequency and untimely feedback of monitoring information. Utility Model Content

[0003] The purpose of this invention is to provide a laser convergence device for tunnel monitoring and measurement to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tunnel monitoring and measurement laser convergence device, comprising a housing, a partition fixedly installed inside the housing, and a first mounting block provided at the top of the partition. One side of the first mounting block is fixedly connected to the side wall of the housing, and a first laser ranging sensor is fixedly installed on one side of the first mounting block. A second laser ranging sensor is obliquely arranged above the first laser ranging sensor, and one end of the second laser ranging sensor is fixedly connected to one end of the second mounting block. The second mounting block is rotatably connected to the inner wall of the housing through a rotating column, and a top limiting screw is threaded through the top of the housing. The bottom end of the top limiting screw abuts against the end of the second mounting block away from the rotating column.

[0005] Preferably, a control board is fixedly installed on the partition inside the housing on one side of the first laser rangefinder sensor.

[0006] Preferably, a battery is fixedly installed at the bottom of the inner wall of the housing, and a back plate is fixedly installed on one side of the housing by several bolts.

[0007] Preferably, the housing has laser emission windows on the side near the first laser rangefinder and the second laser rangefinder, and several control buttons are fixedly installed on the outer wall of the housing.

[0010] Compared with the prior art, the advantages of this utility model are as follows:

[0011] This invention uses a first laser ranging sensor and a second laser ranging sensor to monitor and measure distances at designated locations within a tunnel. When the data monitored by either the first or second laser ranging sensor changes, a signal is sent to the control board. The control board then displays the calculated difference in value (i.e., the measured convergence value) on an external display terminal. A battery provides power to the first laser ranging sensor, the second laser ranging sensor, and the control board. The second laser ranging sensor is fixedly mounted on one side of a second mounting block, and the second mounting block is rotatably connected to the side wall of the housing via a rotating column, facilitating the rotation of the rotating column to measure the distances from the second laser ranging sensor. The angle of the rotating column is adjustable, and a through hole is opened at the center of the rotating column. After the angle of the second laser rangefinder sensor is adjusted, the rotating column is fixed to the side wall of the housing by bolts that match the through hole. The bottom end of the top limit screw abuts against the bottom end of the second mounting block to further limit the second mounting block. The back plate fixedly installed on one side of the housing has mounting grooves on both sides. The back plate is fixed to other equipment structures by bolts that match the mounting grooves. A front cover plate is hinged to the outside of the housing to facilitate the operator to open the housing for maintenance and repair. The control buttons on the outside of the housing, which are electrically connected to the control board, are used to adjust the parameters of the first and second laser rangefinder sensors.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1

[0017] Please see Figures 1-2 The diagram shows a tunnel monitoring and measurement laser convergence device, including a housing 1. A partition is fixedly installed inside the housing 1, and a first mounting block 3 is provided at the top of the partition. One side of the first mounting block 3 is fixedly connected to the side wall of the housing 1, and a first laser ranging sensor 4 is fixedly installed on one side of the first mounting block 3. A second laser ranging sensor 5 is obliquely arranged above the first laser ranging sensor 4, and one end of the second laser ranging sensor 5 is fixedly connected to one end of the second mounting block 6. The second mounting block 6 is rotatably connected to the inner wall of the housing 1 through a rotating column 7, and a top limiting screw 8 is threaded through the top of the housing 1. The bottom end of the top limiting screw 8 abuts against the end of the second mounting block 6 away from the rotating column 7.

[0018] In this embodiment, a control board 10 is fixedly installed on the partition inside the housing 1 on one side of the first laser ranging sensor 4. A battery 11 is fixedly installed on the bottom of the inner wall of the housing 1, and a back plate 2 is fixedly installed on one side of the housing 1 by several bolts. Laser emission windows 9 are respectively provided on the side of the housing 1 near the first laser ranging sensor 4 and the second laser ranging sensor 5. Several control buttons 13 are fixedly provided on the outer wall of the housing 1. A front cover plate 12 is hinged to the outer side of the housing 1.

The first laser ranging sensor 4, the second laser ranging sensor 5 and each control button 13 are electrically connected to one end of the control board 10 by wires.

[0019] Furthermore, the distance measurement process at a designated location in the tunnel is monitored using the first laser distance sensor 4 and the second laser distance sensor 5, respectively. When the data monitored by either the first laser distance sensor 4 or the second laser distance sensor 5 changes, a signal is sent to the control board 10. The control board 10 then displays the calculated difference in value on an external display terminal, i.e., the measured convergence value. The battery 11 provides power to the first laser distance sensor 4, the second laser distance sensor 5, and the control board 10. The second laser distance sensor 5 is fixedly mounted on one side of the second mounting block 6, and the second mounting block 6 is rotatably connected to the side wall of the housing 1 via a rotating column 7, thereby facilitating the rotation of the rotating column 7 to move the second laser distance sensor 5. The angle is adjustable, and a through hole is opened at the center of the rotating column 7. After the angle of the second laser rangefinder 5 is adjusted, the rotating column 7 is fixed to the side wall of the housing 1 by bolts that are compatible with the through hole. The bottom end of the top limiting screw 8 abuts against the bottom end of the second mounting block 6 to further limit the second mounting block 6. The back plate 2, which is fixedly installed on one side of the housing 1, has mounting grooves on both sides. The back plate 2 is fixed to other equipment structures by bolts that are compatible with the mounting grooves. A front cover plate 12 is hinged to the outside of the housing 1 to facilitate the operator to open the housing 1 for maintenance and repair. The control button 13, which is electrically connected to the control board 10, is provided on the outside of the housing 1 to adjust the parameters of the first laser rangefinder 4 and the second laser rangefinder 5.

[0020] The working principle of this utility model is as follows: The first laser ranging sensor 4 and the second laser ranging sensor 5 monitor the ranging process at a designated location in the tunnel. When the data monitored by either the first laser ranging sensor 4 or the second laser ranging sensor 5 changes, a signal is sent to the control board 10. The control board 10 then displays the calculated difference in value on an external display terminal, i.e., the measured convergence value. The battery 11 provides power to the first laser ranging sensor 4, the second laser ranging sensor 5, and the control board 10. The second laser ranging sensor 5 is fixedly mounted on one side of the second mounting block 6, and the second mounting block 6 is rotatably connected to the side wall of the housing 1 via a rotating column 7, thus facilitating the rotation of the rotating column 7 for second laser ranging sensing. The angle of the device 5 is adjustable, and a through hole is opened at the center of the rotating column 7. After the angle of the second laser rangefinder 5 is adjusted, the rotating column 7 is fixed to the side wall of the housing 1 by bolts that are compatible with the through hole. The bottom end of the top limiting screw 8 abuts against the bottom end of the second mounting block 6 to further limit the second mounting block 6. The back plate 2, which is fixedly installed on one side of the housing 1, has mounting grooves on both sides. The back plate 2 is fixed to other equipment structures by bolts that are compatible with the mounting grooves. A front cover plate 12 is hinged to the outside of the housing 1 to facilitate the operator to open the housing 1 for maintenance and repair. The control button 13, which is electrically connected to the control board 10, is provided on the outside of the housing 1 to adjust the parameters of the first laser rangefinder 4 and the second laser rangefinder 5.
