Description

Technical Field

[0002] With the continuous development of subway transportation in my country and the complex terrain conditions along the subway lines, the number of subway tunnels is also increasing year by year. Tunnel geological hazards exposed during long-term operation occur from time to time. Therefore, during daily operation or maintenance, it is necessary to inspect the tunnel lining. At present, the mainstream technology for tunnel inspection is to use vehicle-mounted geological radar combined with manual operations for inspection. Due to the different heights of tunnels, and the limited height of existing equipment during tunnel inspection, when the tunnel vault is high, the existing inspection equipment may cause a blind spot in the inspection, and the inspection range may not be able to fully cover the tunnel vault. The tunnel vault is an area that bears greater stratum pressure and is a key force in the tunnel structure. Utility Model Content

The bottom of the swing rod 33 is movably linked, the top of the second swing rod 33 is fixedly connected to the inner side of the second fixing seat 34, and the other end of the second fixing seat 34 is fixedly connected to the right side of the movable rod 15; the top of the movable rod 15 is fixedly connected with a fixing box 16, and a lining detector 17 is arranged on the right side of the upper surface of the fixing box 16; a signal receiver 23 is arranged on the rear side of the upper surface of the support seat 13; a control panel 3 is fixedly connected to the upper surface of the vehicle body 1; signal generators 24 are respectively arranged on both sides of the top of the control panel 3.

[0020] The working principle is as follows: the output end of the servo motor 7 drives the threaded rod 8 to rotate, and the threaded rod 8 drives the threaded sleeve 9 to move upward clockwise through the threaded connection; while the threaded sleeve 9 moves upward, it cooperates with the sliding sleeve 12 to drive the support seat 13 to move upward, and the support seat 13 drives the fixed box 16 to move upward; when the fixed box 16 reaches a suitable height, the lining detector 17 detects the inner wall of the tunnel; when the lining detector 17 needs to be adjusted, the signal is transmitted to the signal receiver 23 through the signal generator 24, and the signal receiver 23 controls the first electric slider 20 to move rightward in the inner cavity of the first electric slide rail 18, so that the hinge point at the bottom of the first fixed block 19 deflects, thereby driving the first swing rod 22 and the movable rod 15 to deflect to the right, and then driving the lining detector 17 on the top of the fixed box 16 to deflect to the right, so that the lining detector 17 can detect the right side of the inner wall of the tunnel roof; when the first electric slider 20 slides to the left in the inner cavity of the first electric slide rail 18 When the second electric slider 31 is on the left side, it drives the first swing rod 22 to move to the left side, so that the movable rod 15 deflects to the left side, and then drives the lining detector 17 on the top of the fixed box 16 to deflect to the left, so that the lining detector 17 can detect the left side of the inner wall of the tunnel roof; or the signal receiver 23 can also control the second electric slider 31 to move to the right in the inner cavity of the second electric slide rail 30, so that the hinge point at the bottom of the second fixed block 32 deflects, thereby driving the second swing rod 33 and the movable rod 15 to deflect to the right side, and then driving the lining detector 17 on the top of the fixed box 16 to deflect to the right, so that the lining detector 17 can detect the right side of the inner wall of the tunnel roof; when the second electric slider 31 slides to the left side in the inner cavity of the second electric slide rail 30, it drives the second swing rod 33 to move to the left side, so that the movable rod 15 deflects to the left side, and then drives the lining detector 17 on the top of the fixed box 16 to deflect to the left, so that the lining detector 17 can detect the left side of the inner wall of the tunnel roof. Since the top of the first swinging rod 22 is fixedly hinged to the inner side of the first fixing seat 21, and the bottom of the first swinging rod 22 is movably connected to the inner side of the first fixing block 19 through a bearing, the first swinging rod 22 will not shake when the first electric slider 20 does not move. At the same time, since the top of the second swinging rod 33 is fixedly hinged to the inner side of the second fixing seat 34, and the bottom of the second swinging rod 33 is movably connected to the inner side of the second fixing block 32 through a bearing, the second swinging rod 33 will not shake when the second electric slider 31 does not move.

[0021] Example 2

[0022] On the basis of Example 1, a seat 2 is fixedly connected to the upper surface of the vehicle body 1, and the seat 2 is located at the rear side of the control panel 3. The seat 2 is used for the inspectors to sit, which is convenient for the inspectors to sit in the inspection vehicle for tunnel vault inspection. The inspectors can control the signal generator 24 to transmit the signal to the signal receiver 23 through the control panel 3.

[0023] Example 3

[0024] On the basis of Example 1, a camera 25 is provided on the left side of the upper surface of the fixing box 16, and an infrared rangefinder 26 is provided in the middle of the upper surface of the fixing box 16. The distance of the vault can be measured by the camera 25 and the infrared rangefinder 26, and the position of the lining detector 17 can be accurately controlled.

[0025] Example 4

[0026] On the basis of Example 1, the outer side of the threaded sleeve 9 is fixedly connected to a first slider 35, and the outer side of the sliding sleeve 12 is fixedly connected to a second slider 27; a first slide groove 36 is opened on the left side of the inner cavity connected to the plate 6, and a second slide groove 29 is opened on the right side of the inner cavity of the auxiliary plate 10; the outer side of the first slider 35 is slidably connected to the inner cavity of the first slide groove 36, and the outer side of the second slider 27 is slidably connected to the inner cavity of the second slide groove 29.

[0027] Working principle: When the threaded sleeve 9 and the sliding sleeve 12 move upward, the threaded sleeve 9 will drive the first slider to slide upward in the first sliding groove, and the sliding sleeve 12 will drive the second slider 27 to slide upward in the second sliding groove 29, which can ensure the stability of the threaded sleeve 9 and the sliding sleeve 12 during the movement.

[0028] Example 5

[0029] On the basis of Example 1, the top of the threaded rod 8 is fixedly connected with a first limit block 28, and the top of the guide rod 11 is fixedly connected with a second limit block 38; the diameter of the first limit block 28 is larger than the diameter of the threaded sleeve 9; the diameter of the second limit block 38 is larger than the diameter of the sliding sleeve 12. The first limit block 28 can limit the movement of the threaded sleeve 9, and the second limit block 38 can limit the movement of the sliding sleeve 12, so as to prevent the threaded sleeve 9 and the sliding sleeve 12 from falling off during the movement.

[0030] Example 6

[0031] Based on Example 1, a lighting lamp 37 is provided at the front end of the lining detector 17; due to the poor lighting in the tunnel, when the lining detector 17 inspects the tunnel, the lighting lamp 37 can illuminate the inner wall of the tunnel, making it convenient for inspectors to check the inner wall of the tunnel.
