Description

Technical Field

[0001] This utility model belongs to the technical field of railway catenary de-icing, specifically relating to a fast-moving de-icing structure for a catenary de-icing robot. Background Technology

[0002] In frigid regions, ice buildup on railway overhead contact lines can lead to power transmission interruptions, increased wear on pantographs, and even train stoppages, seriously affecting railway operational safety. Traditional methods such as manual de-icing and thermal melting are inefficient, risky, and costly. With the development of automation technology, overhead contact line de-icing robots have emerged, which can replace manual labor in high-pressure and high-altitude environments to perform efficient de-icing operations.

[0003] Currently, during the rapid movement and de-icing operations of overhead contact line de-icing robots, mechanical vibration and residual ice are two relatively hidden but significant problems. When the robot moves at high speed, the slight vibrations generated by the robotic arm or de-icing blades can lead to a decrease in positioning accuracy, which may not only miss some icy areas, but also damage the surface of the conductor due to blade deviation. At the same time, some wet snow or mixed ice can easily re-adhere to the contact line after mechanical breaking. This secondary icing phenomenon will significantly reduce the de-icing effect and may even require the robot to repeat the operation, thus directly affecting the reliability and efficiency of the de-icing operation.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example

[0031] Reference Figures 1-5 This embodiment of the present invention provides a rapid-moving de-icing structure for a contact wire de-icing robot, comprising:

[0032] The drive mechanism 100 includes a bracket 110 for mounting the walking mechanism and a de-icing assembly 120 disposed on the outside of the bracket 110.

[0033] The auxiliary ice-clearing mechanism 200 includes a support rod 210, a groove 220 formed on the outside of the support rod 210, a limiting rod 230 fixedly installed in the inner cavity of the groove 220, a movable sleeve rod 240 movably sleeved on the outside of the limiting rod 230, and a return spring 250 movably sleeved on the outside of the limiting rod 230. One end of the return spring 250 is fixedly connected to the inner wall of the groove 220, and the other end is fixedly connected to the outside of the movable sleeve rod 240.

[0034] And, an ice blowing mechanism 300 used in conjunction with the auxiliary ice clearing mechanism 200.

[0035] Among them, the support frame 110 provides stable support for the walking mechanism, ensuring the stability of the robot when moving on the contact network. The de-icing component 120 works in conjunction with the auxiliary ice-clearing mechanism 200 to form a preliminary de-icing function. The ice-blowing mechanism 300 has the ability to clean up ice chips. The three work together to form a complete de-icing system, effectively solving the problem of poor effect of a single de-icing method.

[0036] Specifically, the auxiliary ice-clearing mechanism 200 also includes a telescopic rod 260 fixedly installed at the bottom of the movable sleeve rod 240, a buffer spring 270 fixedly installed at the outer opening of the movable sleeve rod 240, a scraper plate 280 fixedly installed at the end of the buffer spring 270, and an arc-shaped scraper groove 290 opened on the outer side of the scraper plate 280.

[0037] The movable sleeve 240 and the return spring 250 work together to enable the scraper 280 to adapt to changes in the surface shape of the wire and maintain constant contact pressure. The buffer spring 270 provides flexible buffering when encountering greater resistance to prevent hard impact from damaging the wire. The telescopic rod 260 can adjust the working position of the scraper, so that the mechanism can adapt to wires of different diameters. The design of the arc-shaped scraper groove 290 ensures that the scraped ice chips can fall off in a directional manner.

[0038] Furthermore, the de-icing assembly 120 includes a cylinder 121, a heating tube 122 fixedly installed inside the cylinder 121, a scraper 123 fixedly installed outside the heating tube 122, and a crushing head 124 fixedly installed outside the scraper 123.

[0039] In this process, the heating tube 122 first softens the ice layer, reducing the difficulty of crushing. The scraper 123 drives the crushing head 124 to rotate and crush the ice, forming a dual de-icing method of thermal and mechanical. The cylinder 121 concentrates the heating area to improve thermal efficiency. Compared with a single mechanical crushing method, this combined de-icing structure can more thoroughly remove stubborn ice layers while reducing mechanical impact on the conductor.

[0040] Preferably, the ice blowing mechanism 300 includes a fan 310, a conveying pipe 320 fixedly installed at the end of the fan 310, a pipe head 330 fixedly installed on the outside of the conveying pipe 320, and a guide plate 340 fixedly installed on the outside of the pipe head 330. The ice blowing mechanism 300 also includes a high-pressure airflow nozzle 350 fixedly installed in the inner cavity of the pipe head 330, a main nozzle 360 ​​fixedly installed in the center of the end of the high-pressure airflow nozzle 350, and side nozzles 370 opened around the end of the high-pressure airflow nozzle 350.

[0041] The high-pressure airflow generated by the blower 310 is delivered to the pipe head 330 through the conveying pipe 320. The guide plate 340 optimizes the airflow direction, so that the airflow is concentrated on the surface of the conductor. This airflow conveying system can effectively remove the fine ice chips after crushing, solve the problem of ice chip residue after mechanical de-icing, and avoid secondary icing. The main nozzle 360 ​​of the high-pressure airflow nozzle 350 generates concentrated airflow to impact the main icing area, and the side nozzles 370 form a surrounding airflow to clean the surrounding area. The multi-directional airflow design ensures that the crushed ice chips are completely blown away from the conductor without leaving any dead corners. Compared with the single-direction airflow jet, the cleaning effect is more thorough.

[0042] Furthermore, the drive mechanism 100 also includes a fixed plate 130 fixedly installed on the outside of the de-icing assembly 120, an ice-breaking cylinder 140 fixedly installed on the outside of the fixed plate 130, and a rotating assembly 150 disposed on the outside of the fixed plate 130.

[0043] The fixed plate 130 provides a rigid connection base for each component, ensuring the overall stability of the system. The ice-breaking cylinder 140 enhances the mechanical de-icing strength and can handle thicker ice layers. The rotating component 150 provides stable power output, allowing the de-icing operation to proceed at a uniform speed and ensuring stable de-icing performance even when moving at high speed.

[0044] Furthermore, the rotating assembly 150 includes a fixed plate 151 fixedly mounted on the outside of the fixed disk 130, a servo motor 152 fixedly mounted on the outside of the fixed plate 151, a drive shaft sleeve 153 fixedly mounted on the output end of the servo motor 152, a transmission belt 154 movably sleeved on the outside of the drive shaft sleeve 153, and a driven wheel 155 movably sleeved on the other end of the transmission belt 154. The driven wheel 155 is rotatably mounted on the outside of the fixed disk 130.

[0045] The servo motor 152 drives the driven wheel 155 through the transmission belt 154, which is smoother and quieter than gear transmission. The fixed plate 151 ensures that the motor is installed firmly and avoids vibration. The cooperation between the drive shaft sleeve 153 and the driven wheel 155 realizes efficient power transmission and effectively reduces the impact of mechanical vibration on the de-icing accuracy.

[0046] In use, firstly, the bracket 110 of the drive mechanism 100 drives the walking mechanism to move and position along the contact wire; the heating tube 122 of the de-icing assembly 120 preheats and softens the ice layer, while the scraper 123 drives the crushing head 124 to rotate and crush the ice layer; the movable sleeve 240 of the auxiliary ice-clearing mechanism 200 pushes the scraper 280 to scrape off the residual ice layer under the action of the return spring 250, and the buffer spring 270 provides flexible buffer protection for the wire; the blower 310 of the ice-blowing mechanism 300 generates high-pressure airflow, which blows away the residual ice debris through the main nozzle 360 ​​and the side nozzle 370; finally, the servo motor 152 of the rotating assembly 150 continuously drives the driven wheel 155 through the transmission belt 154 to ensure that the de-icing operation is carried out at a uniform speed.

[0047] In summary, the support 110 of the drive mechanism 100 provides stable support for the walking mechanism; the de-icing assembly 120 softens the ice layer through the heating pipe 122 and then mechanically breaks it up by the crushing head 124; the fixed plate 130 and the ice-breaking cylinder 140 enhance the overall structural strength; the movable sleeve 240 of the auxiliary ice-clearing mechanism 200, under the action of the return spring 250 and the buffer spring 270, enables the scraper 280 to adapt to the surface shape of the wire and maintain constant contact pressure; the arc-shaped scraper groove 290 ensures that the ice chips fall off in a directional manner.

[0048] The ice blowing mechanism 300 forms a three-dimensional airflow field through the main nozzle 360 ​​and side nozzle 370 of the high-pressure airflow nozzle 350. With the help of the guide plate 340, the airflow direction is optimized to thoroughly remove residual ice debris. The rotating component 150 adopts a smooth transmission method using a servo motor 152 and a transmission belt 154 to ensure that the de-icing operation is carried out at a uniform speed. It realizes a complete de-icing process of softening ice, mechanically breaking ice, gently scraping ice, and high-pressure blowing. While ensuring thorough de-icing, it effectively protects the surface of the conductor, significantly improves de-icing efficiency and operational stability, and is suitable for high-speed mobile de-icing operations on overhead contact lines.
