Description
Technical Field
[0001] This utility model relates to the field of thickness detection technology, specifically a tunnel lining thickness detection device. Background Technology
[0002] The tunnel lining thickness detection device is a specialized device used for non-destructive or minimally invasive detection of the actual thickness of tunnel lining concrete. It accurately measures whether the thickness of the lining concrete meets the design requirements, providing data support for tunnel structural safety assessment, defect diagnosis, and maintenance decisions.
[0003] Existing tunnel lining thickness detection devices require workers to hold the equipment at all times when conducting tunnel inspections. Once the workers are exhausted, the equipment may fall, potentially causing a safety accident.
[0004] To address this problem, the present invention provides a tunnel lining thickness detection device. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a tunnel lining thickness detection device, which solves the aforementioned problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a tunnel lining thickness detection device, comprising a dustproof chamber, a fixed vertical plate fixedly connected to the side wall of the dustproof chamber, a high-pressure air pump fixedly connected to one side of the fixed vertical plate, a fixed suction cup connected to one end of the high-pressure air pump, a drive motor fixedly connected to one inner wall of the dustproof chamber, a hydraulic rod fixedly connected to the output end of the drive motor, a drill bit fixedly connected to one end of the hydraulic rod, and an infrared rangefinder fixedly connected to the other inner wall of the dustproof chamber, the inner wall of the infrared rangefinder being rotatably connected to the side wall of the hydraulic rod.
[0007] Preferably, a cooling water tank is fixedly connected to one side of the inner wall of the dustproof chamber, the inner wall of the cooling water tank is fixedly connected to the side wall of the drive motor, a water pump is fixedly connected to the inner wall of the cooling water tank, one end of the water pump is connected to a water delivery hose, one end of the water delivery hose is connected to a water spray ring, and one side of the water spray ring is connected to multiple nozzles.
[0008] Preferably, the plurality of nozzles are arranged at equal intervals, and a filter screen is fixedly connected to the inner wall of each of the plurality of nozzles.
[0009] Preferably, an electric push rod is fixedly connected to the other side of the inner wall of the dustproof chamber, one end of the electric push rod is fixedly connected to the other side of the water spray ring, and the side wall of the water spray ring is slidably connected to the inner wall of the dustproof chamber.
[0010] Preferably, a fixed handle is fixedly connected to the side wall of the dustproof compartment, and the side wall of the fixed handle is covered with an anti-slip rubber sleeve.
[0011] Preferably, a transparent circular plate is fixedly connected to the inner wall of the cooling water tank, and the transparent circular plate is made of tempered glass. Beneficial effects
[0012] This invention provides a device for detecting the thickness of tunnel lining. Compared with the prior art, it has the following advantages:
[0013] (1) When the thickness of the tunnel lining needs to be measured, the staff can place the fixed suction cup on the surface of the tunnel to be measured and start the high-pressure air pump. The high-pressure air pump will use the fixed suction cup to fix the equipment in the tunnel. In this way, the staff will not need to lift the equipment continuously during subsequent equipment testing, thereby reducing the labor intensity of the staff and avoiding safety accidents caused by the staff's physical exhaustion. At this time, the drive motor is started, and the drive motor drives the drill bit to rotate through the hydraulic rod. Then the hydraulic rod is started, and the hydraulic rod drives the drill bit to extend and drill holes in the tunnel lining. After the drill bit finishes drilling, the hydraulic rod drives the drill bit to reset. At this time, the infrared rangefinder is started, and the infrared rangefinder measures the thickness of the tunnel lining. The fixed handle makes it more convenient for the staff to move the equipment. The anti-slip rubber sleeve increases the friction between the staff's palm and the fixed handle, making the staff hold the fixed handle more firmly.
[0014] (2) Before the workers place the fixed suction cup on the tunnel surface, the water pump is started. The water pump will cause the cooling water in the cooling water tank to be sprayed out through the water delivery hose, spray ring and nozzle to wash the tunnel surface and prevent the dust attached to the tunnel surface from affecting the adsorption and fixing effect of the fixed suction cup. In addition, during the drilling process of the drill bit, cooling water can also be sprayed out, which can cool down the drill bit and reduce dust. In addition, the cooling water tank can also cool down the drive motor to prevent the drive motor from being damaged due to excessive temperature due to long-term operation. By setting a filter screen, the waste generated by the drill bit during drilling can be prevented from clogging the nozzle. By setting an electric push rod, the position of the spray ring can be adjusted to prevent the cleaning effect of the equipment on the tunnel from deteriorating when the spray ring and the nozzle are in the same space. The transparent round plate made of tempered glass allows the workers to directly see the remaining amount of cooling water in the cooling water tank in real time, so that the workers can replenish the cooling water in the cooling water tank as soon as possible.

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. Example
[0021] Please see Figure 1 - Figure 4 A tunnel lining thickness detection device includes a dustproof chamber 1, a fixed vertical plate 2 fixedly connected to the side wall of the dustproof chamber 1, a high-pressure air pump 3 fixedly connected to one side of the fixed vertical plate 2, a fixed suction cup 4 connected to one end of the high-pressure air pump 3, a drive motor 15 fixedly connected to one inner wall of the dustproof chamber 1, a hydraulic rod 16 fixedly connected to the output end of the drive motor 15, a drill bit 17 fixedly connected to one end of the hydraulic rod 16, and an infrared rangefinder 18 fixedly connected to the other inner wall of the dustproof chamber 1. The inner wall of the infrared rangefinder 18 is rotatably connected to the side wall of the hydraulic rod 16.
[0022] It should be noted that when the thickness of the tunnel lining needs to be measured, the staff can place the fixed suction cup 4 on the surface of the tunnel to be measured, start the high-pressure air pump 3, and the high-pressure air pump 3 will use the fixed suction cup 4 to attach and fix the equipment in the tunnel. In this way, the staff will not need to hold the equipment up for a long time during subsequent equipment testing, thereby reducing the labor intensity of the staff and avoiding safety accidents due to physical exhaustion. At this time, the drive motor 15 is started, and the drive motor 15 drives the drill bit 17 to rotate through the hydraulic rod 16. Then the hydraulic rod 16 is started, and the hydraulic rod 16 drives the drill bit 17 to extend and drill holes in the tunnel lining. After the drill bit 17 finishes drilling, the hydraulic rod 16 drives the drill bit 17 to return to its original position. At this time, the infrared rangefinder 18 is started to measure the thickness of the tunnel lining.
[0023] In an optional embodiment: a cooling water tank 7 is fixedly connected to one side of the inner wall of the dustproof chamber 1. The inner wall of the cooling water tank 7 is fixedly connected to the side wall of the drive motor 15. A water pump 9 is fixedly connected to the inner wall of the cooling water tank 7. One end of the water pump 9 is connected to a water delivery hose 10. One end of the water delivery hose 10 is connected to a water spray ring 11. A plurality of nozzles 12 are connected to one side of the water spray ring 11.
[0024] It should be noted that before the workers place the suction cup 4 on the tunnel surface, the water pump 9 is started. The water pump 9 will cause the cooling water inside the cooling water tank 7 to be sprayed out through the water delivery hose 10, the water spray ring 11 and the nozzle 12 to wash the tunnel surface and prevent the dust attached to the tunnel surface from affecting the suction cup 4's adsorption and fixation effect. In addition, during the drilling process of the drill bit 17, cooling water can also be sprayed out, which can both cool down the drill bit 17 and reduce dust. Furthermore, the cooling water tank 7 can also cool down the drive motor 15 to prevent the drive motor 15 from being damaged due to excessive temperature caused by prolonged operation.
[0025] In an optional embodiment: a plurality of nozzles 12 are arranged at equal intervals, and a filter screen 13 is fixedly connected to the inner wall of each of the plurality of nozzles 12.
[0026] It should be noted that by setting up the filter screen 13, it is possible to prevent the debris generated by the drill bit 17 during drilling from clogging the inside of the nozzle 12.
[0027] In an optional embodiment: an electric push rod 14 is fixedly connected to the other side of the inner wall of the dustproof chamber 1, one end of the electric push rod 14 is fixedly connected to the other side of the water spray ring 11, and the side wall of the water spray ring 11 is slidably connected to the inner wall of the dustproof chamber 1.
[0028] It should be noted that by setting the electric push rod 14, the position of the water spray ring 11 can be adjusted to prevent the water spray ring 11 and the nozzle 12 from being in the same space, which would cause the equipment to have a poor cleaning effect on the tunnel.
[0029] In an optional embodiment: a fixed handle 5 is fixedly connected to the side wall of the dustproof compartment 1, and an anti-slip rubber sleeve 6 is fitted on the side wall of the fixed handle 5.
[0030] It should be noted that the fixed handle 5 makes it more convenient for staff to move equipment, while the anti-slip rubber sleeve 6 increases the friction between the staff's palm and the fixed handle 5, making the staff hold the fixed handle 5 more firmly.
[0031] In an optional embodiment: a transparent circular plate 8 is fixedly connected to the inner wall of the cooling water tank 7, and the transparent circular plate 8 is made of tempered glass.
[0032] It should be noted that the transparent circular plate 8 made of tempered glass allows staff to directly and in real time view the remaining amount of cooling water inside the cooling water tank 7, so that staff can replenish the cooling water inside the cooling water tank 7 as soon as possible.
[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0034] When it is necessary to detect the thickness of the tunnel lining during operation, the staff can place the fixed suction cup 4 on the surface of the tunnel to be tested, start the high-pressure air pump 3, and the high-pressure air pump 3 will use the fixed suction cup 4 to attach and fix the equipment in the tunnel. In this way, the staff will not need to hold the equipment up for a long time during subsequent equipment testing, thereby reducing the labor intensity of the staff and avoiding safety accidents caused by physical exhaustion. At this time, the drive motor 15 is started, and the drive motor 15 drives the drill bit 17 to rotate through the hydraulic rod 16. Then the hydraulic rod 16 is started, and the hydraulic rod 16 drives the drill bit 17 to extend and drill holes in the tunnel lining. After the drill bit 17 finishes drilling, the hydraulic rod 16 drives the drill bit 17 to return to its original position. At this time, the infrared rangefinder 18 is started to detect the thickness of the tunnel lining.
[0035] Before the workers place the fixed suction cup 4 on the tunnel surface, the water pump 9 is started. The water pump 9 will cause the cooling water inside the cooling water tank 7 to be sprayed out through the water delivery hose 10, the water spray ring 11 and the nozzle 12 to wash the tunnel surface and prevent the dust attached to the tunnel surface from affecting the adsorption and fixing effect of the fixed suction cup 4. In addition, during the drilling process of the drill bit 17, cooling water can also be sprayed out, which can cool down the drill bit 17 and reduce dust. Furthermore, the cooling water tank 7 can also cool down the drive motor 15 to prevent the drive motor 15 from being damaged due to excessive temperature caused by long-term operation.
[0036] By setting up the filter screen 13, it is possible to prevent the debris generated by the drill bit 17 during drilling from clogging the inside of the nozzle 12.
[0037] By setting the electric push rod 14, the position of the water spray ring 11 can be adjusted to prevent the water spray ring 11 and the nozzle 12 from being in the same space, which would cause the equipment to have a poor cleaning effect on the tunnel.
[0038] The fixed handle 5 makes it more convenient for staff to move equipment, while the anti-slip rubber sleeve 6 increases the friction between the staff's palm and the fixed handle 5, making the staff hold the fixed handle 5 more firmly.
[0039] The transparent circular plate 8 made of tempered glass allows staff to directly and in real time view the remaining amount of cooling water inside the cooling water tank 7, so that staff can replenish the cooling water inside the cooling water tank 7 as soon as possible.
