Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, and more specifically, particularly to a mobile monitoring device for tunnel construction. Background Art

[0002] In traditional tunnel construction monitoring, it is usually chosen to install monitoring equipment at a specific location in the tunnel. However, this method has some significant shortcomings. The function of this monitoring method is relatively single. Once the equipment is fixed in a certain location, its viewing angle and monitoring range are limited. This may result in some important construction links or areas not being effectively covered, resulting in monitoring blind spots. These blind spots may hide some potential safety hazards or quality problems, bringing risks to the project. In addition, as the project progresses, the installed monitoring equipment may need to be constantly dismantled and reinstalled. This repeated dismantling and installation process not only consumes a lot of manpower and financial resources, but also prolongs the progress of the project and increases the time cost.

[0003] The utility model patent with announcement number CN219328477U discloses a movable tunnel railway engineering construction monitoring device, which is movable and does not require fixed installation, is easy to put in and recycle, has a simple structure, reasonable layout, multiple functions and high intelligence, and can remotely monitor the situation of the tunnel construction site in real time and in all directions, thus improving the monitoring work efficiency. However, its disadvantage is that it has movable wheels at the bottom of the cabinet, so that the device can move on the ground in the tunnel, but during tunnel construction, the ground objects are relatively complicated, and the ground may be uneven, which makes it relatively difficult to move the device, and the device occupies the ground position, which is also easy to affect the passage of other vehicles, thereby affecting the construction progress.

[0028] The mobile monitoring device for tunnel construction in this embodiment is provided with a hanging rail assembly and a rail crane slidably connected to the hanging rail assembly. By installing the hanging rail assembly on the wall inside the tunnel along the length direction of the tunnel, the rail crane is separated from the ground and moves along the wall inside the tunnel. On the one hand, the movement of the rail crane along the hanging rail assembly will be smoother, and on the other hand, the rail crane does not occupy the ground position and will not hinder the passage of other vehicles. By installing components such as a camera mechanism and a communication mechanism 1 on the rail crane, the construction situation in the tunnel can be monitored.

[0029] In the present embodiment, the hanging rail assembly includes a hanging rail body 8 and a mounting top beam 9. The hanging rail body 8 is composed of a plurality of I-beams connected end to end. A plurality of mounting top beams 9 are arranged on the top of the hanging rail body 8. The mounting top beams 9 are also made of I-beams. One end of the mounting top beam 9 is connected to the top of the hanging rail body 8, and the other end is connected to the inner wall of the tunnel. Specifically, the mounting top beam 9 and the hanging rail body 8 can be connected in a fixed connection or a detachable connection.

As the tunnel construction progresses, the hanging rail components in the completion stage can be removed and new hanging rail components can be installed, forming a circular turnover and saving materials.

[0031] In this embodiment, if Figure 4 As shown, the rail crane includes a top plate 4, a wheel frame 5, a moving wheel 6 and a driving motor 7.

[0034] In this embodiment, the image information obtained by the camera mechanism and the environmental information obtained by the sensor module 10 can be wirelessly transmitted to the client platform through the communication mechanism 1; the communication mechanism 1 is a public mobile communication network communication module; so that the staff of the supervision unit can remotely and in real time obtain relevant information of the tunnel construction site, and it is also helpful to calculate relevant information through intelligent image recognition in the later stage.

[0035] The mobile monitoring device for tunnel construction in this embodiment also includes a sensor module 10 and an alarm mechanism 14. The alarm mechanism 14 is an audible and visual alarm. The alarm mechanism 14 is installed at the lower end of the camera mechanism and is connected to the controller 2.

The length of the entire installation top beam 9 can also be adjusted to adjust the distance between the rail crane and the inner wall of the tunnel.
