Description

[0002] As an important land transportation infrastructure, railways play a critical role in the global economic and social development. As railway transportation continues to develop towards high speed and heavy load, unprecedented high requirements are placed on the safety and stability of railway tracks. Under the long-term huge dynamic load brought by train operation, railway tracks will inevitably undergo various deformations. The track is inspected by a robot equipped with an infrared detection device. This robot can move autonomously along the track, measure relevant parameters of the track surface by emitting infrared rays and receiving reflected light, and then determine whether the track is deformed.

[0003] However, the above technologies often have the following defects: Infrared detection methods face severe challenges under severe weather conditions. When encountering severe weather such as heavy rain, heavy snow, and dense fog, infrared rays will be greatly affected. In heavy rain, a large number of raindrops will scatter and absorb infrared rays, causing the energy of infrared rays to be greatly attenuated during the transmission process, resulting in the intensity of the reflected light becoming weaker and the signal being unstable. At the same time, the irregular movement of raindrops will also interfere with the propagation path of infrared rays, causing deviations in the originally accurate measurement of the time difference of reflected light, which in turn affects the accuracy of track deformation detection.

[0023] The sealing mechanism includes a slide groove opened in the connecting block 2 and connected to the through hole, and a sealing plate 12 for sealing the mounting tube 11 is slidably connected in the slide groove, and a first spring is fixedly connected between the bottom surface of the sealing plate 12 and the inner wall of the slide groove, and the sealing plate 12 is made of magnetic material, and an electromagnet 13 which is magnetic to the sealing plate 12 is fixedly connected to the top surface of the inner wall of the slide groove; when the pressure sensor 5 senses a change in the pressure value, the present application will start the electromagnet 13 for 4 seconds to 5 seconds, at which time the sealing plate 12 will be sucked by the electromagnet 13, so that the sealing plate 12 no longer seals the mounting tube 11, and the marking liquid in the storage chamber 8 can enter the hollow groove 10 from the mounting tube 11 and the connecting tube 9, and finally flow out from the liquid outlet, and after the electromagnet 13 is closed, the first spring will pull the sealing plate 12 to reset, so that the sealing plate 12 seals the mounting tube 11.

[0025] The interior of the connecting rod 15 is hollow, and the top of the connecting rod 15 is connected to a funnel 16. The inner wall of the connecting rod 15 is fixedly connected to a guide rod 17. The surface of the guide rod 17 is sealingly and slidably connected to a sealing column 30 that seals the bottom end of the connecting rod 15. A moving component that drives the sealing column 30 to move is provided in the storage chamber 8. When the marking liquid in the storage chamber 8 needs to be added, the electromagnet 13 can be controlled to open so that the mounting tube 11 is no longer sealed. At this time, gas can flow in the storage chamber 8, and then the connecting rod 15 is pulled upward, so that the connecting rod 15 drives the pressure plate 14 to move upward. During the movement, the moving component drives the sealing column 30 to detach from the bottom end of the connecting rod 15, close the electromagnet 13, allow the sealing plate 12 to seal the mounting tube 11, and then inject the marking liquid into the funnel 16.

At the same time, the sealing column 30 is controlled by the moving component to seal the bottom end of the connecting rod 15. Through the above mechanism, when the marking liquid in the storage chamber 8 is insufficient, the marking liquid in the storage chamber 8 can be added in time.

[0026] The moving component includes a magnetic ring 18 fixedly connected to the top surface of the sealing column 30, and the top surface of the storage chamber 8 is fixedly connected with a ring 19 sleeved on the connecting rod 15, and the ring 19 can be magnetically attracted to the magnetic ring 18, and a third spring is fixedly connected between the top surface of the sealing column 30 and the side wall of the guide rod 17; during the upward movement of the connecting rod 15, the magnetic ring 18 will be magnetically attracted to the ring 19, and then when the connecting rod 15 continues to move, the sealing column 30 will be detached from the bottom end of the connecting rod 15, and then the marking liquid will be injected into the storage chamber 8, and after the injection is completed, the connecting rod 15 is moved downward to disengage the magnetic ring 18 from the ring 19, and at this time the third spring will pull the sealing column 30 to move and reset on the guide rod 17, thereby sealing the bottom end of the connecting rod 15.

[0027] An alarm 22 is fixedly connected to the top surface of the connecting block 2, a first contact 20 is fixedly connected to the bottom surface of the storage cavity 8, and a second contact 21 is fixedly connected to the bottom surface of the pressing plate 14 at a position corresponding to the first contact 20. The alarm 22 can be activated when the first contact 20 contacts the second contact 21. The marking liquid in the present application will gradually decrease with use. At this time, the pressing plate 14 will also gradually move downward until the first contact 20 contacts the second contact 21, at which time the alarm 22 will be activated to sound an alarm. The alarm 22 means that the marking liquid in the storage cavity 8 is insufficient, so as to immediately remind the staff to add marking liquid.

[0028] The side wall of the connecting plate 3 is fixedly connected with a fixing plate 23, and the rotating shaft on the fixing plate 23 is connected with a second rotating shaft, and the bottom end of the second rotating shaft is fixedly connected with a cylinder 24, and the side wall of the cylinder 24 is fixedly connected with a plurality of groups of cleaning bristles 25, and a rotating assembly for rotating the cylinder 24 is provided on the connecting plate 3; since there are inevitably some debris such as gravel on the track, these debris may cause the roller 7 passing on the track to mistakenly trigger the pressure sensor 5, thereby affecting the deformation detection of the track. When the roller 7 in the present application rotates on the track through the above-mentioned mechanism, the rotating assembly can be used to drive the cylinder 24 to rotate, and at this time, the cleaning bristles 25 can clean the track, and the cleaning bristles 25 are made of rigid material, and the cleaning bristles 25 can prevent impurities such as gravel from being on the track, thereby ensuring the smooth operation of the roller 7.

[0029] The rotating assembly includes a third rotating shaft, which is rotatably connected to the top surface of the connecting plate 3, a first gear 26 is fixedly connected to the first rotating shaft, a second gear 27 meshing with the first gear 26 is fixedly connected to the third rotating shaft, and a third gear 28 meshing with the second gear 27 is fixedly connected to the second rotating shaft; in the present application, when the roller 7 rotates, the first rotating shaft will drive the first gear 26 to rotate, thereby allowing the first gear 26 to drive the second gear 27 to rotate, and then allowing the third gear 28 to drive the second rotating shaft to rotate, so that the cylinder 24 drives the cleaning bristles 25 to clean the debris on the track.

[0030] Embodiment 2: Figure 7 As shown, in contrast to Example 1, another implementation of the present invention is that an elastic ring 29 fitted with the liquid outlet is fixedly connected to the inner wall of the hollow groove 10, and a group of shrinkage holes are opened on the elastic ring 29 corresponding to the position of the liquid outlet; after the marking liquid in the present application enters the hollow groove 10, it will be pressurized by pressure. When the marking liquid in the hollow groove 10 reaches a certain pressure, the marking liquid will expand the shrinkage holes on the elastic ring 29, so that the marking liquid passes through the shrinkage holes and then sprays out from the liquid outlet, so that the marking liquid can be evenly sprayed out from all the liquid outlets.

[0031] Working principle: When it is necessary to detect the deformation of the railway track, the detection robot 1 can be placed on the track. At this time, the roller 7 will contact the side wall of the track, and then the detection robot 1 will walk on the track. If the track is deformed, the roller 7 will pass through the deformed part. At this time, the roller 7 will drive the connecting plate 3 to move, so that the pressure provided by the detection spring 6 to the pressure sensor 5 changes, so that the pressure sensor 5 sends this data to the detection robot 1, and the detection robot 1 uploads this data to the cloud to achieve the effect of safe deformation detection of the track. The above-mentioned detection mechanism can avoid being affected by various bad weather conditions and greatly improve the accuracy of track deformation detection; when the pressure sensor 5 senses a change in the pressure value, the application The sealing mechanism can be made to no longer seal the mounting tube 11. At this time, the marking liquid in the storage chamber 8 will flow into the hollow groove 10 along the mounting tube 11 and the connecting tube 9, and finally flow from the liquid outlet to the deformed part of the rail to mark it, so that subsequent staff can find the deformed part in time; when the pressure sensor 5 senses a change in the pressure value, the application will start the electromagnet 13 for 4 seconds to 5 seconds. At this time, the sealing plate 12 will be sucked by the electromagnet 13, so that the sealing plate 12 no longer seals the mounting tube 11. At this time, the marking liquid in the storage chamber 8 can enter the hollow groove 10 from the mounting tube 11 and the connecting tube 9, and finally flow out from the liquid outlet. After the electromagnet 13 is closed, the first spring will pull the sealing plate 12 to reset, so that the sealing plate 12 seals the mounting tube 11; When the mounting tube 11 in the present application discharges the marking liquid, the second spring will push the pressure plate 14 so that the pressure plate 14 squeezes the marking liquid to apply pressure to the marking liquid, so that the marking liquid can be sprayed out from the liquid outlet onto the track to increase the marking range of the marking liquid and make it easier for the staff to find the deformation of the track; when the marking liquid in the storage chamber 8 needs to be added, the electromagnet 13 can be controlled to open so that the mounting tube 11 is no longer sealed. At this time, gas can flow in the storage chamber 8, and then the connecting rod 15 is pulled upward so that the connecting rod 15 drives the pressure plate 14 to move upward. During the movement, the moving component drives the sealing column 30 to detach from the bottom end of the connecting rod 15, closes the electromagnet 13, and allows the sealing plate 12 to seal the mounting tube 11, and then injects the marking liquid into the funnel 1 6, and then the marking liquid will be injected into the storage chamber 8 along the inside of the connecting rod 15. After the injection is completed, the connecting rod 15 is moved downward, and the sealing column 30 is controlled by the moving component to seal the bottom end of the connecting rod 15. Through the above mechanism, when the marking liquid in the storage chamber 8 is insufficient, the marking liquid in the storage chamber 8 can be added in time; during the upward movement of the connecting rod 15, the magnetic ring 18 will be magnetically attracted by the sleeve ring 19, and then when the connecting rod 15 continues to be moved, the sealing column 30 will be separated from the bottom end of the connecting rod 15, and then the marking liquid will be injected into the storage chamber 8. After the injection is completed, the connecting rod 15 is moved downward, so that the magnetic ring 18 is separated from the sleeve ring 19. At this time, the third spring will pull the sealing column 30 to move and reset on the guide rod 17, thereby sealing the bottom end of the connecting rod 15; The marking liquid in the present application will gradually decrease with use, and at this time the pressure plate 14 will gradually move downward until the first contact 20 contacts the second contact 21, which will activate the alarm 22 to sound an alarm. The alarm 22 means that the marking liquid in the storage chamber 8 is insufficient, and the staff is reminded to add the marking liquid in time. Since there will inevitably be some debris such as gravel on the track, these debris will cause the roller 7 passing on the track to mistakenly trigger the pressure sensor 5, thereby affecting the deformation detection of the track. Through the above mechanism, the roller 7 in the present application is carried out on the track When rotating, the cylinder 24 can be driven to rotate with the help of the rotating component. At this time, the cleaning bristles 25 can clean the track. The cleaning bristles 25 are made of rigid material. The cleaning bristles 25 can prevent impurities such as gravel from being on the track, thereby ensuring the smooth operation of the roller 7; in the present application, when the roller 7 rotates, the first rotating shaft will drive the first gear 26 to rotate, so that the first gear 26 drives the second gear 27 to rotate, and then the third gear 28 drives the second rotating shaft to rotate, so that the cylinder 24 drives the cleaning bristles 25 to clean the debris on the track.
