Description

Technical Field

[0001] The present application relates to the technical field of tunnel monitoring, and more specifically, to a device for monitoring holes behind a shield tunnel wall and cracks in a pipe segment. Background Art

[0002] Shield tunnel construction technology is widely used in subway tunnel construction, where the shield segment is the permanent support structure of the tunnel, ensuring the safety of the tunnel during construction and operation. The voids behind the shield tunnel segment wall and general segment quality problems may lead to serious tunnel safety accidents. In order to ensure the quality of tunnel construction, it is necessary to regularly inspect the voids behind the segment wall and the quality of the segment.

[0003] The document with prior art publication number CN220289849U provides a device for monitoring voids and cracks in the wall of a shield tunnel. In the related technology of the device, a transverse motor, a first longitudinal motor and a second longitudinal motor can realize all-round motion acquisition scanning of a radar detector and a high-speed camera. Compared with traditional manual information collection, the utility model has high efficiency, low monitoring cost and higher accuracy.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device monitors the cavity and the pipe segment behind the shield tunnel wall, it needs to stop monitoring intermittently, and the monitoring efficiency is low.

[0005] In view of this, we propose a device for monitoring the voids behind the shield tunnel wall and cracks in the segments. Utility Model Content

[0006] In order to improve the problems raised in the above background technology, the present application provides a shield tunnel wall cavity and segment crack monitoring device.

[0018] By adopting the above technical solution, the electric lifting column is used to drive the device structure to limit the lifting and fitting inside the tunnel for height limitation, while the friction wheel is closely fitted to the inner wall of the tunnel for limitation. At the same time, the driving vehicle body can be more stable when moving along the track laid in the tunnel for monitoring, and it is less likely for components to collide with the inner wall of the tunnel.

[0022] By adopting the above technical solution, the worm is used to drive the lead screw to rotate, and the lead screw will extend the screw barrel column to a limited position and push it outward, thereby increasing the lighting range of the lighting lamp and providing a good lighting environment for the monitor.

[0023] As an optional solution to the technical solution of the present application document, a movable groove is provided on one side of the arc rod, and a soft brush arc plate is elastically connected to the movable groove through a spring member for sliding, and an arc tooth plate capable of meshing and transmitting with an irregular gear is fixedly connected to one side of the soft brush arc plate, and the two arc tooth plates are arranged in an offset structure.

[0024] By adopting the above technical solution, the elastically limited soft brush arc plate is used to limit the transmission of the irregular gear, so that the irregular gear can have a gap transmission with the arc tooth plate installed at one end of the soft brush arc plate during continuous rotation, thereby realizing the cyclic reciprocating cleaning action of the soft brush arc plate.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. This application utilizes the driving vehicle body to drive the worm and the worm gear shaft to engage and transmit, so that the arc rod fixedly connected to the outside of the worm gear shaft is unfolded, and the monitors are distributed in the tunnel aperture for all-round monitoring and processing, thereby ensuring that the driving vehicle body fully monitors the internal conditions of the tunnel during movement and improving the efficiency of monitoring work.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings.

[0034] Reference Figure 1-4 A device for monitoring a hollow space behind a shield tunnel wall and cracks in a segment of a shield tunnel according to an embodiment of the present application includes:

[0035] A driving vehicle body 1 is placed on the tunnel track and moves;

[0036] The electric lifting column 2 is fixedly connected to the surface of the driving vehicle body 1;

[0037] The parts frame 3 is fixedly connected to the other end of the electric lifting column 2;

[0038] A servo motor 4 is fixedly connected to one side of the parts frame 3;

[0039] The worm 5 is rotatably connected in the parts frame 3 and is fixedly connected to the servo motor 4;

[0040] The worm gear shaft 6 is symmetrically connected to the parts frame 3 and meshes with the worm 5 for transmission;

[0041] An arc rod 7 equipped with multiple monitors is fixedly connected to one end of the worm gear shaft 6.

[0042] The shield tunnel wall rear cavity and segment crack monitoring device utilizes the driving vehicle body 1 to drive the worm 5 to mesh with the worm gear shaft 6, so that the arc rod 7 fixedly connected to the outside of the worm gear shaft 6 is unfolded, and the monitors are distributed in the tunnel aperture for all-round monitoring, thereby ensuring that the driving vehicle body 1 fully monitors the internal conditions of the tunnel during movement and improving the monitoring efficiency.

[0043] Reference Figure 3 and Figure 2 In the shield tunnel wall rear cavity and segment crack monitoring device recorded in the embodiment of the present application, an arm 31 is hingedly installed on one side of the part frame 3, and the other end of the arm 31 is rotatably connected to a friction wheel 32, and an elastic support rod 33 is hingedly installed on one side of the arm 31, and the other end of the elastic support rod 33 is hingedly installed on one side of the part frame 3;

[0044] One side of the arm 31 is rotatably connected to a pulley shaft 34, and the pulley shaft 34 and the pulley fixedly connected to one end of the friction wheel 32 are driven by friction through a synchronous belt, and one end of the pulley shaft 34 is fixedly connected to a universal joint, and the irregular gear 35 fixedly connected to the other end of the universal joint is rotatably connected to the part frame 3 through a supporting column;

[0045] A guide frame 36 is fixedly connected to one side of the parts frame 3, an extension screw column 37 is slidably connected inside the guide frame 36, and a screw rod 38 is threadedly connected inside the extension screw column 37 with a lighting lamp fixedly installed on one end, and the other end of the screw rod 38 is fixedly connected to the worm 5 through a coupling.

[0046] The shield tunnel wall rear cavity and segment crack monitoring device uses an electric lifting column 2 to drive the device structure to limit the lifting and fitting of the tunnel interior for height limitation. The friction wheel 32 is tightly fitted and limited to the inner wall of the tunnel, which can make the driving vehicle body 1 more stable when moving along the track laid in the tunnel for monitoring, and it is not easy for parts to collide with the inner wall of the tunnel. The friction wheel 32 is tightly fitted and limited to the inner wall of the tunnel. As the driving vehicle body 1 moves, the friction wheel 32 rotates, so that the rotating friction wheel 32 drives the irregular gear 35 and the soft brush arc plate 71 to transmit under the connection transmission of the universal joint, so as to realize the circular movement of the soft brush arc plate 71, clean the inner wall of the tunnel, and ensure a good monitoring environment for the monitor.

[0047] Reference Figure 4 and Figure 2 In the shield tunnel wall rear cavity and segment crack monitoring device recorded in the embodiment of the present application, a movable groove is opened on one side of the arc rod 7, and a soft brush arc plate 71 is elastically connected to the movable groove through a spring member. An arc tooth plate 72 that can mesh with the irregular gear 35 for transmission is fixedly connected to one side of the soft brush arc plate 71, and the two arc tooth plates 72 are arranged in an offset structure.

[0048] The shield tunnel wall rear cavity and segment crack monitoring device utilizes the elastically limited soft brush arc plate 71 to limit the transmission of the irregular gear 35, so that the irregular gear 35 can have gap transmission with the arc tooth plate 72 installed at one end of the soft brush arc plate 71 during continuous rotation, thereby realizing the cyclic reciprocating cleaning action of the soft brush arc plate 71.

[0049] Working principle: After the driving vehicle body 1 is placed on the divided track in the tunnel, the operator controls the electric lifting column 2 to drive the part frame 3 to move up and up. When the arm 31 under the hinged limit of the elastic support rod 33 drives the friction wheel 32 to be tightly pressed and limited with the top surface of the tunnel, the height adjustment of the electric lifting column 2 is stopped, and the servo motor 4 is controlled to rotate according to the preset program limit, driving the worm 5 to mesh with the worm gear shaft 6, so that the arc rod 7 installed outside the worm gear shaft 6 can be unfolded to fit the inner wall aperture of the tunnel;

[0050] When the driving vehicle body 1 moves along the track, multiple monitors fixedly installed on one side of the arc rod 7 perform multi-directional detection of the cavity and the pipe segment behind the tunnel wall, and the friction wheel 32 in rolling friction contact with the inner wall of the tunnel drives the irregular gear 6 to engage and transmit with the arc tooth plate 72 under the universal joint transmission connection with the telescopic function, and pulls the soft brush arc plate 71 elastically limited in the arc rod 7 to limit rotation. When the irregular gear 6 disengages from the arc tooth plate 72, the elastically stretched soft brush arc plate 71 resets, thereby realizing the cleaning operation of the soft brush arc plate 71 on the inner wall of the tunnel.
