Description

Technical Field

[0001] The utility model relates to the technical field of rail-hanging type inspection robots, in particular to a rail-hanging type inspection robot. Background Art

[0002] The rail-mounted inspection robot is a type of rail-mounted robot. It uses ultrasonic and infrared technologies to detect surrounding objects and personnel, thereby preventing collisions when the inspection robot walks on the rail.

[0003] The patent currently published with the publication number CN220446456U discloses a rail-mounted inspection robot, comprising a robot walking mechanism, a telescopic mechanism, a pan-tilt mechanism, a lower shell, an upper shell, and a walking track. The outer surface of the walking track overlaps the interior of the robot walking mechanism, the top of the telescopic mechanism is fixedly mounted on the bottom of the robot walking mechanism, one side of the pan-tilt mechanism is connected to one side of the telescopic mechanism, and the upper shell is fixedly mounted on the exterior of the robot walking mechanism and the telescopic mechanism by bolts. The above-mentioned device can be used to display the status of the robot's operation and the specific content of the inspection items through the setting of a display screen, and a second ultrasonic detector installed at the bottom of the lower shell can detect whether there is an obstacle under the pan-tilt mechanism when it descends, so as to prevent the pan-tilt mechanism from colliding with the obstacle, ensuring the practicality of the device.

[0004] Although the above device solves the problem of easy collision of the bottom of the inspection robot, the following problems still exist:

[0005] When the rail-mounted inspection robot operates outdoors and encounters heavy snow, snow will accumulate on the rail. When the inspection robot passes by the snow, the heat emitted by the inspection robot will cause the bottom of the snow to melt. Due to the low external temperature, the melted snow water will freeze to form icicles on both sides of the rail. When the inspection robot runs along the rail, these icicles will hinder the movement of the inspection robot and collide with the outer shell of the inspection robot. At the same time, the reflective effect of the icicles may also affect the normal operation of the sensors installed on the inspection robot. Utility Model Content

[0008] Furthermore, two symmetrically arranged fixed plates are fixedly connected to the lower side of the top of the fixed frame, and a rotating shaft is rotatably connected between the two fixed plates.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] like Figures 1 to 5 As shown, a rail-mounted inspection robot includes a robot body 1 and a rail 21 connected to the upper part of the robot body 1. A fixing frame 2 is fixedly connected to one side of the robot body 1. The cross section of the fixing frame 2 is L-shaped. Two symmetrically arranged scrapers 3 are slidably connected to the lower side of the top of the fixing frame 2. The cross section of the scraper 3 is triangular. Each scraper 3 is detachably connected to a flexible scraper strip 4 at one end away from the fixing frame 2. The outer wall of the flexible scraper strip 4 is in contact with the surface of the rail 21. The fixing frame 2 and the robot body 1 are fixedly connected by bolts 16.

[0023] like Figure 1 As shown, the structure of a rail-mounted inspection robot in the present invention is similar to that of an existing rail-mounted inspection robot, such as a rail-mounted inspection robot disclosed in the patent publication number CN220446456U. The main improvement of the present invention is that the inspection robot can process the snow on the rail. Figures 1 to 5As shown, when a rail-mounted inspection robot in the present invention is in use, during the operation of the inspection robot, the robot body 1 will drive the scraper 3 and the flexible scraper 4 to move through the fixed frame 2. In heavy snow weather, the flexible scraper 4 and the scraper 3 will scrape the snow on the surface of the track 21 off the track 21, thereby effectively preventing the accumulation of snow on the hanging rail and forming icicles after melting at the bottom; the design of the flexible scraper 4 not only ensures a close fit with the surface of the track 21, thereby improving the efficiency of clearing snow, but also its softness can reduce the wear on the surface of the track 21 and protect the track 21 from damage; at the same time, in daily use, the flexible scraper 4 can also clean leaves and the like that have fallen on the track 21 to avoid affecting the movement of the inspection robot; through the bolt 16, when the flexible scraper 4 is not needed, the fixed frame 2 can be removed as a whole, thereby avoiding wear caused by meaningless contact between the flexible scraper 4 and the track 21; in the process of removing snow, the liquid melted at the bottom of the snow can act as a lubricant for the flexible scraper 4 and the track 21, reducing the wear on the flexible scraper 4.

[0024] By installing a fixing frame 2 on the robot body 1, installing a scraper 3 and a flexible scraper strip 4 on the fixing frame 2, and utilizing the mutual cooperation between the flexible scraper strip 4 and the scraper 3, the snow on the track 21 is cleared, thereby preventing the accumulation of snow and the subsequent formation of ice, and ensuring the smooth movement and operating efficiency of the inspection robot.

[0025] like Figures 2 to 5 As shown, two symmetrically arranged fixed plates 7 are fixedly connected to the lower side of the top of the fixed frame 2, and a rotating shaft 8 is rotatably connected between the two fixed plates 7. The outer wall of the rotating shaft 8 is sleeved with two driven wheels 9 and a cam 10. The driven wheel 9 is located between the two fixed plates 7, and the cam 10 is located between the two driven wheels 9. The outer wall of the driven wheel 9 fits the surface of the track 21. Each scraper 3 is fixedly connected to a moving rod 5 on both sides, and moving grooves 6 corresponding to the position of the moving rod 5 are opened on both sides of the top of the fixed frame 2. The scraper 3 is connected to a moving component on the side close to the cam 10.

[0026] like Figures 3 to 5 As shown, the moving assembly includes a spring 11, a fixed block 17 and a moving wheel 18. Two symmetrically arranged springs 11 are fixedly connected between the two scrapers 3. A fixed block 17 is fixedly connected to the side of each scraper 3 close to the cam 10. The end of the fixed block 17 away from the scraper 3 is rotatably connected to the moving wheel 18, and the outer wall of the moving wheel 18 is in contact with the outer wall of the cam 10.

[0027] Specifically, during the movement of the robot body 1, the driven wheel 9 will rotate under the friction of the track 21, thereby driving the rotating shaft 8 to rotate, and the rotating shaft 8 will then drive the cam 10 to rotate. Due to the irregular setting of the cam 10 and the two moving wheels 18 will be tightly attached to the outer wall of the cam 10 under the action of the spring 11, the cam 10 will push the two moving wheels 18 to move, and then push the two scrapers 3 to move, so that the flexible scraper 4 moves back and forth along the direction of the track 21, forming a vibration effect. This vibration effect can more effectively scrape off snow and debris. The vibration can also help the melted snow water flow away faster, preventing it from freezing again to form icicles, which helps to improve the snow removal efficiency of the flexible scraper 4.

[0028] like Figures 3 to 5 As shown, two symmetrically arranged T-shaped rods 12 are fixedly connected to the lower side of the top of the fixing frame 2, and two symmetrically arranged sliding rods 13 are fixedly connected to the side of each scraper 3 close to the cam 10, and sliding grooves 14 corresponding to the positions of the sliding rods 13 are provided at both ends of the bottom of the T-shaped rods 12.

[0029] Specifically, the T-bar 12 and the sliding bar 13 can ensure that the scraper 3 vibrates along a straight line, ensuring close contact between the flexible scraper strip 4 and the track 21, thereby effectively clearing snow and debris, and avoiding possible deviation or shaking of the scraper 3 during vibration.

[0030] like Figure 3 and Figure 4 As shown, the outer wall of the driven wheel 9 is covered with an anti-slip cover 15.

[0031] Specifically, the anti-slip sleeve 15 can increase the friction between the driven wheel 9 and the track 21, ensure the stable rotation of the driven wheel 9, provide power to the cam 10, and prevent the driven wheel 9 from slipping; the anti-slip sleeve 15 is usually made of materials with a high friction coefficient, such as rubber, polyurethane, etc. These materials have excellent wear resistance and elasticity, and can maintain stable friction performance during long-term use.

[0032] like Figure 5 As shown, a connecting rod 19 is fixedly connected to one side of the flexible scraper strip 4 close to the scraper 3 , and a slot 20 corresponding to the position of the connecting rod 19 is opened at one end of the scraper 3 .

[0033] Specifically, by utilizing the mutual cooperation between the connecting rod 19 and the slot 20, when the flexible scraper strip 4 is highly worn, the flexible scraper strip 4 can be quickly replaced, thereby saving maintenance time and improving work efficiency.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
