Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of track inspection trolleys, and in particular relates to an anti-derailment roller for 4C intelligent inspection trolleys. Background Technology
[0002] The 4C intelligent inspection trolley is a small inspection device used to check the suspension status of the overhead contact line. Equipped with a high-definition camera, it can automatically detect the suspension status of the contact line, analyze and identify various equipment defects, and effectively cover vulnerable areas such as station lines and branch lines that cannot be inspected by contact line inspection vehicles, work vehicles, or other dedicated track vehicles. In the operation and maintenance management of railway power supply equipment, the 4C intelligent inspection trolley plays a crucial role in timely detection of potential equipment hazards and ensuring power supply safety.
[0003] However, conventional trolley rollers are cylindrical. When these cylindrical rollers travel on the rails, the different turning radii of the left and right rails cause inconsistent roller speeds, which can easily lead to trolley derailment, jamming, and slippage. Utility Model Content
[0004] The purpose of this invention is to provide an anti-derailment roller for a 4C intelligent inspection trolley, which solves the problem that conventional trolley rollers are cylindrical. When these cylindrical rollers travel on the rails, the different turning radii of the left and right rails cause inconsistent roller speeds, which can easily lead to derailment, jamming, and slippage of the trolley.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is an anti-derailment roller for a 4C intelligent inspection vehicle, which includes two guide rails and an anti-derailment mechanism is provided between the two guide rails.
[0007] The anti-detachment mechanism includes a chassis, with an intelligent detection trolley body fixedly connected to the top surface of the chassis. Two fixed frames are fixedly connected to the bottom surface of the chassis. A fixed bracket is fixedly connected to the inner wall of the front fixed frame. A dual-axis motor is fixedly connected to the inner wall of the fixed bracket. Rotating rod 1 is fixedly connected to both output ends of the dual-axis motor via couplings. Rotating rod 2 is rotatably connected to the inner wall of the rear fixed frame. Gear 1 is fixedly connected to the ends of the two rotating rods 1 and 2 that are far apart from each other. Internal gear rings are fixedly connected to the sides of the two fixed frames that are far apart from each other.
[0008] Cleaning mechanisms are provided on the opposite sides of both fixed frames.
[0009] Furthermore, two L-shaped plates are fixedly connected to the left and right sides of the chassis, and connecting discs are fixedly connected to the inner walls of the four L-shaped plates via bearings.
[0010] Furthermore, three rotating shafts are fixedly connected to each of the four connecting discs on their adjacent sides, and gears are fixedly connected to the inner walls of several rotating shafts. The several rotating shafts mesh with the inner walls of the four internal gear rings respectively.
[0011] Furthermore, rollers are fixedly connected to the four connecting discs on opposite sides, and the outer walls of the four rollers are provided with several anti-slip textures. The four rollers are in contact with the two guide rails respectively.
[0012] Furthermore, all four rollers are conical rollers, all four rollers are made of nylon, and all four rollers have a cone angle of 3 degrees.
[0013] Furthermore, the cleaning mechanism includes threaded rods rotatably connected to four L-shaped plates, the bottom ends of the four threaded rods extending into the interior of the L-shaped plates, the top ends of the four threaded rods being fixedly connected to knobs, and the bottom ends of the four threaded rods being rotatably connected to connecting plates.
[0014] Furthermore, each of the four L-shaped plates has two sliding rods extending through its top surface, and the bottom ends of the two sliding rods extend into the interior of the L-shaped plate. The bottom ends of the corresponding two sliding rods are fixedly connected to the top surfaces of the four connecting plates.
[0015] Furthermore, each of the four connecting plates has four push rods running through it, and each of the four connecting plates is slidably connected to several push rods. A cleaning brush is fixedly connected to the bottom end of each of the four push rods, and each of the four cleaning brushes is in contact with four rollers. Springs are wound around the outer walls of each of the push rods, and one end of each of the springs is fixedly connected to the cleaning brush, while the other end of each of the springs is fixedly connected to the bottom surface of the connecting plate.
[0016] This utility model has the following beneficial effects:
[0017] 1. Equipped with an anti-detachment mechanism, when the dual-axis motor on the drive frame drives the two rotating rods to rotate, the entire device can move under the drive of the rotating rods. The rotating rod at the rear will also rotate, causing the four gears to rotate, which in turn will drive multiple gears to rotate. Under the double limit of gears one and the internal gear ring, the gears two rotate around gears one, which in turn drives the connecting disc inside the L-shaped plate to rotate. When the connecting disc rotates, it drives the rollers to rotate on the top surface of the guide rail, which in turn drives the entire device to move. The surface of the rollers is knurled to increase friction, making the entire device more stable during movement. The cone angle of multiple rollers is 3 degrees, which ensures that the contact point with the guide rail can be automatically adjusted when turning, so that the entire device can smoothly pass through curves and forks when traveling on the guide rail, avoiding derailment and slippage.
[0018] 2. By incorporating a cleaning mechanism, multiple sliding rods limit the movement of the connecting plate, ensuring that the connecting plate can only move vertically up and down. When the screw rod is rotated by turning the knob, the connecting plate moves downward, allowing the cleaning brush on the connecting plate to approach the roller and clean its surface. This prevents impurities from adhering to the roller during operation, thus avoiding slippage and further improving the overall stability of the device. When the cleaning brush contacts the roller, the push rod and spring work together to buffer and adjust the pressure of the cleaning brush on the roller, preventing excessive pressure from obstructing the roller's rotation. This also ensures that the cleaning brush can contact the roller for cleaning.
[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-5 As shown, this utility model is an anti-derailment roller for a 4C intelligent inspection vehicle, including two guide rails 1, and an anti-derailment mechanism 2 is provided between the two guide rails 1;
[0030] The anti-detachment mechanism 2 includes a chassis 21. A smart detection trolley body 4 is fixedly connected to the top surface of the chassis 21. Two fixed frames 22 are fixedly connected to the bottom surface of the chassis 21. A fixed bracket 23 is fixedly connected to the inner wall of the front fixed frame 22. A dual-axis motor 24 is fixedly connected to the inner wall of the fixed bracket 23. Rotary rods 25 are fixedly connected to both output ends of the dual-axis motor 24 via couplings. A second rotating rod 26 is rotatably connected to the inner wall of the rear fixed frame 22. Gears 27 are fixedly connected to the ends of the two rotating rods 25 and 26 that are far apart from each other. Internal gear rings 28 are fixedly connected to the sides of the two fixed frames 22 that are far apart from each other. Two L-shaped plates 29 are fixedly connected to the left and right sides of the chassis 21. Connecting discs 291 are fixedly connected to the inner walls of the four L-shaped plates 29 via bearings. Three rotating shafts 2 are fixedly connected to the sides of the four connecting discs 291 that are close to each other. 92. Gears 293 are fixedly connected to the inner walls of several rotating shafts 292. The rotating shafts 292 mesh with the inner walls of four internal gear rings 28. Rollers 294 are fixedly connected to the opposite sides of the four connecting discs 291. The outer walls of the four rollers 294 are provided with several anti-slip textures 295. The four rollers 294 are in contact with two guide rails 1. The four rollers 294 are all conical rollers. The four rollers 294 are all made of nylon. The cone angle of the four rollers 294 is 3 degrees. By setting an anti-detachment mechanism 2, the surface of the rollers 294 is knurled to increase friction and make the whole device more stable during movement. The cone angle of multiple rollers 294 is 3 degrees, which ensures that the contact point with the guide rail 1 can be automatically adjusted when turning, so that the whole device can smoothly pass through curves and forks when traveling on the guide rail 1, avoiding derailment and slippage.
[0031] Cleaning mechanisms 3 are provided on opposite sides of the two fixed frames 22. Each cleaning mechanism 3 includes threaded rods 31 rotatably connected to four L-shaped plates 29. The bottom ends of the four threaded rods 31 extend into the interior of the L-shaped plates 29, and the top ends of the four threaded rods 31 are fixedly connected to knobs 32. The bottom ends of the four threaded rods 31 are rotatably connected to connecting plates 33. Two sliding rods 34 pass through the top surfaces of the four L-shaped plates 29, and the bottom ends of the two sliding rods 34 extend into the interior of the L-shaped plates 29. The bottom ends of the corresponding two sliding rods 34 are fixedly connected to the top surfaces of the four connecting plates 33. Four top rods 35 pass through the four connecting plates 33, and the four connecting plates 33 are slidably connected to several top rods 35. Cleaning brushes 36 are fixedly connected to the bottom ends of the corresponding four top rods 35, and the four cleaning brushes 36 are respectively connected to four rollers. The rollers 294 are in contact with each other. The outer walls of several push rods 35 are all wrapped with springs 37. One end of each spring 37 is fixedly connected to a cleaning brush 36, and the other end of each spring 37 is fixedly connected to the bottom surface of the connecting plate 33. By setting up a cleaning mechanism 3, the cleaning brush 36 on the connecting plate 33 is brought close to the roller 294 to clean the surface of the roller 294, so as to prevent the roller 294 from slipping due to the accumulation of impurities during the operation, and further improve the stability of the overall device during operation. When the cleaning brush 36 is in contact with the roller 294, the push rods 35 and springs 37 cooperate to buffer and adjust the pressure of the cleaning brush 36 on the roller 294, so as to prevent the roller 294 from being blocked due to excessive pressure, and at the same time, it allows the cleaning brush 36 to contact the roller 294 to clean it.
[0032] A specific application of this embodiment is as follows: By providing an anti-detachment mechanism 2, when the dual-axis motor 24 on the drive frame 23 drives the two rotating rods 25 to rotate, the entire device can move under the drive of the rotating rods 25. The rotating rod 26 located at the rear will also rotate accordingly, thereby causing the four gears 27 to rotate and drive multiple gears 293 to rotate. Under the double limiting of gears 27 and internal gear ring 28, gears 293 rotate around gears 27, thereby driving the L-shaped plate. The connecting disc 291 inside 29 rotates, and when the connecting disc 291 rotates, it drives the roller 294 to rotate on the top surface of the guide rail 1, thereby driving the entire device to move. The surface of the roller 294 is knurled to increase friction, making the entire device more stable during movement. The cone angle on the multiple rollers 294 is 3 degrees, which ensures that the contact point with the guide rail 1 can be automatically adjusted when turning, so that the entire device can smoothly pass through curves and forks when traveling on the guide rail 1, avoiding derailment and slippage.
[0033] By incorporating a cleaning mechanism 3, multiple sliding rods 34 limit the movement of the connecting plate 33, ensuring that the connecting plate 33 can only move vertically up and down. When the screw rod 31 is rotated by turning the knob 32, the connecting plate 33 can be moved downwards, allowing the cleaning brush 36 on the connecting plate 33 to approach the roller 294 and clean the surface of the roller 294. This prevents impurities from sticking to the roller 294 during operation, thus avoiding slippage and further improving the stability of the overall device during operation. When the cleaning brush 36 contacts the roller 294, the push rod 35 and the spring 37 work together to buffer and adjust the pressure of the cleaning brush 36 on the roller 294, preventing excessive pressure from causing the roller 294 to become obstructed and stop rotating. At the same time, this allows the cleaning brush 36 to contact the roller 294 and clean it.
