Description

Technical Field

[0001] The invention relates to the field of track detection, in particular to a track detection robot. Background Art

[0002] Track inspection refers to the process of inspecting and evaluating the condition of railway tracks to ensure that they are safe, stable and meet operating standards. Through regular or irregular inspections of the tracks, inspectors can discover potential faults, damage or abnormalities, so that necessary repairs or adjustments can be taken to avoid accidents or operational interruptions caused by track problems.

[0003] In order to avoid accidents during human inspection, the existing inspection method uses robot inspection instead. However, robot inspection does not have the flexibility of human inspection, and the robot may derail during the inspection process, which brings certain dangers. The inspection robot does not have certain protective measures to protect the safety of the equipment, causing losses. Moreover, the robot does not have the ability to decelerate after derailment, and emergency braking may cause the robot to roll over. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The protective wheel is forced to contact the ground, and the support rod will be lifted up and hit the metal block. The rebound of the spring will squeeze the support rod downward, and the support rod will slide downward to replace the front wheel to move, thereby preventing the front wheel from derailing and moving on the ground to cause damage. The protective wheel has steering ability, which can effectively prevent the equipment from overturning. At the same time, during the operation of the equipment, the first reduction wheel is close to the track, and the first reduction wheel is driven to rotate by friction. The slider is then made to slide through the second connecting rod, so that the second reduction wheel is close to the track. Due to the gear transmission, the second reduction wheel turns in the opposite direction to the first reduction wheel, which can cause the second reduction wheel to produce reverse friction on the track to produce a deceleration effect, thereby preventing the braking effect of the equipment from failing due to derailment, or rolling over due to emergency braking without a deceleration auxiliary device, causing secondary damage.

DETAILED DESCRIPTION

[0026] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0027] like Figure 1 - Figure 8 A track inspection robot shown includes a shell assembly 100, including a support plate 101, and a track detector 103 fixedly installed on the left side of the support plate 101, tunnel detectors 104 are fixedly installed on both sides of the track detector 103, two groups of L-shaped plates 108 are fixedly installed on the left bottom end of the support plate 101, servo motors 109 are fixedly installed on the inner sides of the two groups of L-shaped plates 108, and front wheels 110 are fixedly installed on the output end of the servo motor 109, a central processing unit 102 is fixedly installed on the top of the support plate 101, a roadbed detector 105 is fixedly installed on the right side of the support plate 101, track flaw detectors 106 are fixedly installed on both sides of the support plate 101, two groups of rear wheels 107 are fixedly installed on the bottom ends of the two groups of track flaw detectors 106, and double tracks 111 are provided at the bottom ends of the front wheels 110 and the rear wheels 107.

[0028] The protection component 200 includes a circular tube 201 fixedly installed in the middle of the bottom end of the track detector 103, a hollow tube 202 fixedly installed at the bottom end of the circular tube 201, a first connecting shaft 203 fixedly installed at the bottom end of the hollow tube 202, a support rod 204 slidably installed inside the hollow tube 202, a first telescopic rod 205 rotatably installed between the support rod 204 and the first connecting shaft 203, after the protection wheel 207 is forced to contact the ground, due to inertia, the support rod 204 will be lifted up and hit the metal block 210, a first rotating rod 206 is rotatably installed at the bottom end of the support rod 204, and protection wheels 207 are rotatably installed on both sides of the first rotating rod 206, and first limit blocks are fixedly installed on both sides of the inside of the circular tube 201 208. A spring 211 is rotatably installed at the top inner part of the circular tube 201. The spring 211 is a strong spring, and its elastic force can support the protection wheel 207 to operate. At the same time, its impact force can lift the spring 211. A metal block 210 is fixedly installed at the bottom end of the spring 211. Second limit blocks 209 are fixedly installed on both sides of the metal block 210. The second limit block 209 is in contact with the first limit block 208. The metal block 210 drives the second limit block 209 to rotate on the first limit block 208. When the second limit block 209 loses its limit, the rebound of the spring 211 squeezes the support rod 204 downward, and the support rod 204 slides downward. The protection wheel 207 has the ability to turn, which effectively prevents the equipment from rolling over.

[0029] The deceleration assembly 300 includes a transverse plate 302, which is connected to the support plate 101 through a connecting rod. A slider 318 is slidably installed on the front side of the bottom end of the transverse plate 302, and a connecting plate 308 is fixedly installed on the top of the slider 318. A third connecting shaft 307 is fixedly installed on one side of the connecting plate 308, and a second connecting rod 306 is rotatably installed in the middle of the third connecting shaft 307. A second connecting shaft 301 is fixedly installed in the middle of the first telescopic rod 205, and a first connecting rod 304 is rotatably installed in the middle of the second connecting shaft 301. A limiting tube 303 is fixedly installed on the top of the transverse plate 302, and the first connecting rod 304 slides in the limiting tube 303. The ends of the first connecting rod 304 and the second connecting rod 306 are rotatably installed. A universal ball 305 is installed. The extension of the first telescopic rod 205 drives the first connecting rod 304 to pull the second connecting rod 306 to move leftward. The second connecting rod 306 then makes the connecting plate 308 slide outward, thereby driving the sliding block 318 to slide. A fixed block 312 is fixedly installed on the rear side of the bottom end of the cross plate 302. A third rotating rod 313 is rotatably installed in the middle of the fixed block 312. A second bevel gear 314 is fixedly installed in the middle and lower part of the third rotating rod 313. A first reduction wheel 315 is fixedly installed at the bottom end of the third rotating rod 313. A supporting block 309 is fixedly installed in the middle of the bottom end of the cross plate 302. A second rotating rod 310 is rotatably installed at the bottom end of the supporting block 309. The rear side of the second rotating rod 310 is fixedly installed with the first bevel gear 314. 11. The first bevel gear 311 is meshed with the second bevel gear 314, and the first reduction wheel 315 is close to the track. The first reduction wheel 315 is driven to rotate by friction, and the first bevel gear 311 is rotated by meshing transmission, and the second rotating rod 310 installed with the first bevel gear 311 rotates, and the second telescopic rod 316 is fixedly installed on the front side of the second rotating rod 310, and the third bevel gear 317 is fixedly installed on the end of the second telescopic rod 316. The third bevel gear 317 is driven to rotate by the installed second telescopic rod 316, and the fourth rotating rod 319 installed with the fourth bevel gear 320 is rotated by meshing transmission. The second reduction wheel 321 at the bottom of the fourth rotating rod 319 is driven by the transmission, and the slider 318 is rotated. A fourth rotating rod 319 is rotatably installed in the middle part, a fourth bevel gear 320 is fixedly installed in the middle and lower part of the fourth rotating rod 319, a second reduction wheel 321 is fixedly installed at the bottom end of the fourth rotating rod 319, the fourth bevel gear 320 is meshingly connected with the third bevel gear 317, a fixing plate 322 is arranged between the third rotating rod 313 and the fourth rotating rod 319 and the second rotating rod 310, the second reduction wheel 321 is close to the track, due to the gear transmission, the second reduction wheel 321 and the first reduction wheel 315 turn in the opposite direction, the second reduction wheel 321 can produce reverse friction on the track, produce a deceleration effect, prevent the braking effect of the equipment from failing due to derailment, or roll over due to emergency braking without a deceleration auxiliary device, causing secondary damage.

[0030] When the track is damaged, the front wheel 110 suddenly derails and the entire equipment begins to shake. At this time, after the protection wheel 207 is forced to contact the ground, due to inertia, the support rod 204 will be lifted up and hit the metal block 210. In addition, the shaking of the equipment causes the metal block 210 to drive the second limit block 209 to rotate on the first limit block 208. When the second limit block 209 loses its limit, the rebound of the spring 211 squeezes the support rod 204 downward, and the support rod 204 slides downward. At the same time, the length exceeds the diameter of the front wheel 110, and then takes over the movement of the front wheel 110 to prevent the front wheel 110 from moving on the ground after derailing and causing damage. In addition, the protection wheel 207 has the ability to steer, which effectively prevents the equipment from overturning. At this time, when the support rod 204 slides down, it drives the extension of the first telescopic rod 205. At the same time, during the operation of the equipment, the first reduction wheel 315 is close to the track. The first reduction wheel 315 is driven to rotate by friction, and the first bevel gear 315 is engaged through the transmission. 311 rotates, the second rotating rod 310 equipped with the first bevel gear 311 rotates, and the third bevel gear 317 is driven to rotate through the installed second telescopic rod 316, and the fourth rotating rod 319 equipped with the fourth bevel gear 320 is rotated through meshing transmission, and the second reduction wheel 321 at the bottom is driven by the transmission of the fourth rotating rod 319 to rotate, and the extension of the first telescopic rod 205 drives the first connecting rod 304 to pull the second connecting rod 306 to move left, and the second connecting rod 306 then makes the connecting plate 308 slide outward, thereby driving the slider 318 to slide, so that the second reduction wheel 321 is close to the track. Due to the gear transmission, the second reduction wheel 321 and the first reduction wheel 315 turn in the opposite direction, which can make the second reduction wheel 321 produce reverse friction on the track, produce a deceleration effect, and prevent the braking effect of the equipment from failing due to derailment, or roll over due to emergency braking without a deceleration auxiliary device, causing secondary damage.
