Description

Technical Field

[0001] This utility model belongs to the field of detecting anomalies at the bottom of subway or high-speed rail tracks, and particularly relates to a device for taking pictures of the bottom of subway or high-speed rail tracks. Background Technology

[0002] Railways are a vital national transportation infrastructure and a major artery of national economic development, bearing heavy passenger and freight transport responsibilities and closely related to the lives and production of the people. Currently, my country's railway operating mileage has exceeded 150,000 kilometers. To ensure railway transport safety, providing the location and quality of railway rail flaw detection is particularly important. In my country's traditional periodic equipment inspections, track inspection instruments are widely used to check the static geometric parameters of the tracks.

[0003] Steel rails are the main component of railway tracks. Their function is to guide the wheels of locomotives and rolling stock, bear the enormous pressure of the wheels, and transmit it to the sleepers. Steel rails must provide the wheels with a continuous, smooth, and least resistance-prone rolling surface. Because of this, the railway system needs to frequently conduct flaw detection inspections on the rails to ensure the safe operation of locomotives.

[0004] Track bottom flaw detection refers to the inspection of the track bottom using flaw detection instruments. The inspection includes checking for rail corrosion, electrical burns, and crescent-shaped spalling. Existing flaw detection equipment primarily detects fatigue and welding defects at the rail head and web, neglecting defects at the track bottom. This forces monitoring and maintenance personnel to manually inspect the track bottom, increasing their workload. Furthermore, existing flaw detection equipment is bulky, requiring multiple workers to carry it onto the track for operation. This makes the equipment inconvenient to move, easily damaged, and difficult to disassemble and repair.

[0005] Currently, track bottom inspection uses a flat reflector. A worker holds a reflector with a rod, slowly moving the mirror along the bottom of the track, observing changes in the track's surface color through the mirror. Any abnormalities are carefully examined to determine if maintenance is needed. Foreign objects on the track bottom require visual inspection while looking down. This manual inspection is physically demanding. The worker must maintain the mirror's height to avoid contact with the track and ground, and keep the mirror as parallel as possible to the track surface. Repeated observations are necessary when abnormalities are detected. The worker's arms and body tire easily, requiring frequent breaks, resulting in low work efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a device for taking pictures of the bottom of subway or high-speed rail tracks, in order to solve the problem that existing flaw detection equipment cannot detect the bottom of the track, and the bottom needs to be monitored manually, which leads to low efficiency.

[0007] This utility model adopts the following technical solution: a device for taking photos of the bottom of subway or high-speed rail tracks, comprising: Support base plate, horizontally set; The bent arm tube is L-shaped and hollow inside. Its lower end is bent horizontally and used to extend into the underside of the subway or high-speed rail track, while its upper end is bent upward and fixed to the support base plate. The shooting unit is installed inside the bent boom tube, and its shooting lens is set to extend out of the lower end of the bent boom tube to take pictures of the bottom of the subway or high-speed rail track. The lower end of the bent boom tube is used to extend into the underside of the subway or high-speed rail track, so that the shooting unit can take pictures of the bottom of the track, so as to determine whether there are any abnormalities at the bottom of the track through the pictures.

[0008] The beneficial effects of this utility model are: This invention can detect damage such as track corrosion, electrical burns, and crescent-shaped chips on the bottom of the track. Maintenance personnel can push the device along the track to perform flaw detection while walking, instead of having to lie on the rails and use the reflection principle of a mirror to visually identify the damage on the bottom of the track each time. This improves the efficiency of flaw detection on the bottom of the track and reduces manual operation costs.

[0009] This invention uses a camera lens of a shooting unit to extend into the bottom of subway or high-speed rail tracks to take photos of the bottom of the tracks. These photos are then sent to an external processing module, which uses an image recognition system to process the photos and determine whether there are any abnormalities at the corresponding track locations. This invention, by incorporating a pull ring, a brake line, and a bearing, allows the pull ring to be pulled by the brake line, causing the upper end of the bent boom tube to rotate. This, in turn, causes the lower end of the bent boom tube to rotate upwards and move away from the bottom of the track. This facilitates the upward rotation of the lower end of the bent boom tube when encountering a sleeper, allowing it to move away from the underside of the track. When the invention passes a sleeper, the brake line is released, causing the lower end of the bent boom tube to return to the bottom of the track for monitoring, thereby improving the efficiency of flaw detection at the bottom of the track. This utility model uses a front roller, a rear roller, a left anti-tipping roller, and a right anti-tipping roller to ride on the track, which facilitates the movement of the entire device along the track for monitoring. This prevents the entire device from swaying left and right or tilting forward and backward during smooth travel, allowing the entire device to firmly grip the monorail surface and travel stably. It also avoids strong vibrations that could affect the monitoring accuracy and image quality when the device crosses sleepers or travels. Attached Figure Description

[0014] This utility model discloses a device for taking photos of the bottom of subway or high-speed rail tracks, such as... Figure 1-4 As shown, it includes: a support base plate 10, a bending arm tube 11, and a shooting unit 12.

[0015] The base plate 10 is set horizontally.

[0016] The bending arm tube 11 is L-shaped and hollow inside. The lower end of the bending arm tube 11 is bent horizontally and used to extend into the lower side of the subway or high-speed rail track 15. The upper end of the bending arm tube 11 is bent upward and installed on the upper side of the support base plate 10.

[0017] The shooting unit 12 is installed inside the bent arm tube 11. The shooting lens of the shooting unit 12 extends out of the lower end of the bent arm tube 11. The shooting unit 12 is used to extend into the bottom of the subway or high-speed rail track 15 to take pictures of the bottom of the track 15.

[0018] The lower end of the bent boom tube 11 is used to extend into the underside of the subway or high-speed rail track 15, so that the shooting unit 12 can take pictures of the bottom of the track 15, so as to determine whether there is any abnormality at the bottom of the track 15 through the pictures.

[0019] The present invention also includes: a front roller 13, which is mounted on the lower front side of the support base plate 10 via two front mounting plates; the front roller 13 is used to move along the top of the upper side of the track 15, thereby facilitating the forward movement of the entire device.

[0020] like Figure 5 As shown, the present invention also includes: a rear roller 14, which is mounted on the lower rear side of the support base plate 10 via two rear mounting plates; the rear roller 14 is used to cooperate with the front roller 13 to move along the top of the upper side of the track 15, thereby facilitating the forward movement of the entire device.

[0021] This utility model also includes: a left center rod, which is vertically arranged, with its upper end fixedly connected to the lower side of the support base plate 10, and its lower end extending downward.

[0022] The left anti-tipping wheel 17 is fitted and fixed to the lower end of the left center rod. The left anti-tipping wheel 17 is used to roll along the left side wall of the track 15 when the whole device moves forward, thereby preventing the whole device from tilting to the left.

[0023] This utility model also includes: a right center rod, which is vertically arranged and is arranged opposite to the left center rod. The upper end of the right center rod is fixedly connected to the lower side of the support base plate 10, and the lower end of the right center rod extends downward.

[0024] like Figure 5As shown, the right anti-reverse wheel 19 is sleeved and fixed at the lower end of the right center rod. The right anti-reverse wheel 19 is used to roll along the right side wall of the track 15 when the entire device moves forward, and then cooperate with the left anti-reverse wheel 17 to ensure that the entire device is stuck on the track 15.

[0025] This utility model also includes: an elastic element 20, which is horizontally arranged. One end of the elastic element 20 is fixed to the middle of the left center rod, and the other end of the elastic element 20 is fixed to the middle of the right center rod. By tightening the left center rod and the right center rod, the left anti-reverse wheel 17 and the right anti-reverse wheel 19 are tightened, so that the left anti-reverse wheel 17 and the right anti-reverse wheel 19 clamp the track 15, ensuring the horizontal state of the entire device.

[0026] like Figure 6 As shown, this utility model also includes: a fixing plate 26, which is "n"-shaped and located on the upper side of the supporting base plate 10. The lower end of the fixing plate 26 is fixedly connected to the upper side of the supporting base plate 10. A through hole is provided on one side of the fixing plate 26, and a hollow wire guide screw is installed in the through hole. The wire guide screw is used for the lower end of the gate wire 24 to pass through and be tied to the pull ring 18. By setting the fixing plate 26, the gate wire 24 can be pulled by the gate wire 24 to rotate clockwise after being pulled, thus avoiding the gate wire 24 being directly pulled upward after being pulled.

[0027] This utility model also includes: a clamping plate 21, which is located on the lower side of the supporting base plate 10. The clamping plate 21 is U-shaped, and the elastic element 20 is installed in its inner cavity. The upper end of the clamping plate 21 is fixedly connected to the lower side of the supporting base plate 10. Two limiting grooves 22 are vertically opened through the clamping plate 21. The limiting grooves 22 are respectively used for the left center rod and the right center rod to pass through, thereby limiting the left center rod and the right center rod by the clamping plate 21 to prevent the left center rod and the right center rod from deflecting forward or backward.

[0028] This utility model also includes: a guard plate 23, which is "n"-shaped and located on the upper side of the supporting base plate 10. The lower end of the guard plate 23 is fixedly connected to the upper side of the supporting base plate 10. A bearing is installed in the inner cavity of the guard plate 23. The bearing is used to install the upper end of the bent boom tube 11. A pull ring 18 is fixedly connected to the upper end of the bent boom tube 11. The pull ring 18 is used to tie the brake line 24. The brake line 24 is used to pull the upper end of the bent boom tube 11 to rotate through the pull ring 18, so that the lower end of the bent boom tube 11 also rotates upward and leaves the bottom of the track 15 when passing the sleeper.

[0029] This utility model also includes: a push rod 25, the lower end of which is hinged to the upper side of the support base plate 10, and the upper end of which is used for personnel to hold and push the entire device forward.

[0030] The upper end of the gate line 24 extends along the push rod 25 and is fixed to the upper end of the push rod 25, thereby making it easier for personnel to pull the gate line 24.

[0031] The abnormality mentioned in this utility model refers to the presence of foreign objects at the bottom of the track 15, or surface defects on the bottom surface of the track 15 that affect safety, such as electric current burns or vibration cracks.

[0032] For the rotation angle of the bend around the arm tube 11, such as Figure 4 As shown, no excessive rotation is required. Simply place the pull ring 18 on the bent arm tube 11 at the end away from the brake line 24. During the process of pulling the brake line 24, since the pull ring 18 is fixed on one side of the bent arm tube 11, the pull ring 18 will rotate clockwise by 30-90 degrees. At this time, the upper end of the bent arm tube 11 will also rotate, and the lower end of the bent arm tube 11 will also rotate clockwise. Thus, the lower end of the bent arm tube 11 will rotate out from the bottom of the track 15, detach from the ground of the track 15, and facilitate crossing the sleeper.

[0033] The method of using this utility model is as follows: When monitoring of track 15 is required, this utility model is placed on the upper side of track 15, so that the front roller 13, rear roller 14, left anti-tipping roller 17, and right anti-tipping roller 19 ride on track 15 to ensure the entire device is level. Then, the push rod 2525 pushes the entire device forward along track 15. During the movement, the camera lens of the shooting unit 1212 extends into the bottom of the subway or high-speed rail track 1515 to take pictures of the bottom of track 1515 and sends the pictures to the external processing module, so that the processing module can identify and judge the pictures. When encountering a sleeper, the pull ring 18 is pulled by the brake line 24, which in turn pulls the upper end of the bent arm tube 11 to rotate slightly, so that the lower end of the bent arm tube 11 rotates upward and leaves the bottom of track 15. When this utility model passes the sleeper, the brake line 24 is released, so that the lower end of the bent arm tube 11 returns to the bottom of track 15 for monitoring.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
