Description

Technical Field

[0001] The present invention relates to the technical field of rail cleaning, in particular to a rail cleaning device for railway maintenance. Background Art

[0002] In the railway transportation system, the operating status of the rails is directly related to the safety and timeliness of train operation. When rain and snow are frequent in winter, ice is easily attached to the surface of the rails. These ice layers not only increase the friction resistance between the train wheels and the rails, but may also lead to risks such as extended braking distance and wheel-rail slippage. In severe cases, it may even cause safety accidents such as train delays and derailment. Therefore, timely removal of ice from the surface of the rails is one of the core tasks of winter railway maintenance. However, existing rail de-icing and cleaning equipment has obvious shortcomings in ice-breaking efficiency, continuity and thoroughness, and it is difficult to meet the needs of efficient railway operation and maintenance.

[0003] Traditional rail de-icing equipment mostly uses rigid knocking or mechanical scraping to break ice. The core components of this type of equipment have a fixed contact method with the rails. During the ice-breaking process, it is easy for them to get stuck due to factors such as uneven hardness of the ice layer and protrusions on the rail surface. Once a jam occurs, the equipment needs to be shut down for manual processing, resulting in interruption of the ice-breaking action. This not only prolongs the de-icing time, but may also cause damage to equipment components due to repeated starts and stops. At the same time, the force points of rigid knocking are concentrated, and often only local ice layers can be broken, making it difficult to achieve uniform ice breaking. The ice layers in some areas will remain due to insufficient force and require repeated operations to be removed, further reducing the de-icing efficiency. In addition, the ice-breaking and ice-shoveling processes of existing equipment are mostly independent of each other. After the ice-breaking device completes the ice breaking, ice-shoveling equipment needs to be deployed separately to clean the ice chips. There is a time difference in the connection between the two processes. During this period, the remaining broken ice may freeze again due to the low temperature, forming a new ice layer, increasing the difficulty of secondary cleaning.

[0004] Therefore, the development of a rail cleaning equipment that can achieve continuous ice breaking, uniform crushing, and efficient ice shoveling has become an urgent need to ensure the safety of railway transportation in winter and improve railway maintenance efficiency. The railway maintenance rail cleaning equipment of the present invention is designed based on the above background, aiming to solve the technical pain points of traditional equipment through innovative structure, and provide an efficient solution for railway winter de-icing.

[0012] As a further solution of the present invention: a counterweight block is further provided on the lower surface of the mounting plate near one side.

[0013] As a further solution of the present invention: the ice scraping mechanism includes a vertical rod fixedly mounted on the lower surface of the mounting plate, a mounting frame fixedly mounted on the bottom end of the vertical rod, a lifting plate movably provided in the mounting frame, an ice scraping module provided on one side of the lifting plate for scraping off the ice on the surface of the rail, and an adjustment component provided in the mounting frame for adjusting the height of the lifting plate in the mounting frame.

[0014] As a further solution of the present invention: the ice scraping module includes a movable plate movably arranged on one side of the lifting plate, a movable rod is fixedly installed on the outer wall of the movable plate close to the lifting plate, and the movable rod passes through the lifting plate, a spring is sleeved on the outer side of the movable rod, one end of the spring is connected to the movable plate, and the other end of the spring is connected to the lifting plate, an ice scraping assembly is provided on the outer wall of the movable plate, and a push plate is fixedly installed on the outer wall of the lifting plate close to the movable plate, which is used to prompt the ice scraping assembly to tilt when the movable plate approaches the lifting plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention provides a railway maintenance track cleaning device. When the cleaning device moves stably on the track with the help of a walking assembly, a driving motor drives the rotating shaft, a rotating rod and a mounting rod to operate, so that the hammer block rotates around the rotating shaft to hammer the ice layer. The design of the hammer block being rotatably installed at the end of the mounting rod allows it to naturally cross the track after hammering, completely avoiding the jamming problem of traditional rigid hammering. This structure ensures that the ice-breaking action is continuous and uninterrupted, and there is no need to stop the machine to deal with obstructions. It not only reduces equipment loss, but also ensures the continuity of ice-breaking operations, greatly improving basic ice-breaking efficiency.

[0019] The distance adjustment mechanism can be used to flexibly adjust the distance between the mounting rod and the rotating rod, and different hammer blocks can be adjusted to different positions to form an "offset hammering" mode. This design prevents the striking positions of each hammer block from overlapping, making the force on the ice layer on the rail more dispersed. Compared with traditional concentrated hammering, it can avoid local ice residue due to insufficient force, making the ice layer more evenly broken, clearing obstacles for subsequent ice shoveling, and improving the thoroughness of ice breaking.

[0020] After the ice layer is broken, the shovel mechanism at the bottom of the mounting plate can simultaneously and quickly shovel away the crushed ice while the equipment is moving. No additional process is required from ice crushing to ice debris removal, realizing an integrated "crushing-shoveling" operation. This process saves the connection time of the two processes of traditional equipment, avoids secondary freezing of crushed ice, greatly improves the overall de-icing efficiency, reduces the ice adhesion time, and reduces the risk of train delays.

DETAILED DESCRIPTION

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1-9 As shown in FIG. 1 , a railway maintenance rail cleaning device provided by an embodiment of the present invention includes a mounting plate 101, a traveling assembly 102 that matches the rail is fixedly mounted on the bottom of the mounting plate 101, a fixing plate 103 is fixedly mounted on the bottom of the mounting plate 101, a rotating shaft 104 is rotatably mounted between the fixing plates 103, a driving motor 105 is fixedly mounted on the outer wall of the fixing plate 103, and the driving end of the driving motor 105 is connected to the rotating shaft 104, and multiple fixing members are fixedly mounted on the outer side of the rotating shaft 104. The rotating rods 106 are arranged in a circular pattern with equal distances, and the ends of the rotating rods 106 are provided with mounting rods 107, and the ends of the mounting rods 107 are rotatably connected to hammer blocks 108. The system also includes: a distance adjustment mechanism, which is arranged between the rotating rods 106 and the mounting rods 107, and is used to connect the rotating rods 106 and the mounting rods 107 and adjust the distance between the rotating rods 106 and the mounting rods 107; and an ice scraping mechanism, which is arranged below the mounting plate 101, and is used to scrape off the ice layer on the surface of the rail that is broken by the hammer blocks 108.

[0033] When rain and snow come in winter and ice forms on the surface of the rail, the cleaning device can be placed on the rail and driven to move on the rail surface by means of the walking assembly 102. During the movement, the rotating shaft 104 is driven to rotate by the driving motor 105, and the rotating shaft 104 can drive the hammer block 108 at the end of the mounting rod 107 to rotate around the rotating shaft 104 with the help of the rotating rod 106, thereby realizing the hammering operation on the ice layer on the rail surface. Moreover, since the hammer block 108 is rotatably mounted on the end of the mounting rod 107, it can naturally cross the rail after hammering, avoiding the interruption of rotation due to jamming, ensuring the continuous and stable ice-breaking action, and solving the problem that traditional rigid knocking is easily obstructed. At the same time, the distance between the mounting rod 107 and the rotating rod 106 can be flexibly adjusted by the distance adjustment mechanism. Different hammer blocks 108 can be adjusted to different positions during use. In this way, it is possible to achieve that the positions at which different hammer blocks 108 hammer into the ice layer on the rail surface are all different. This "offset hammering" design makes the force on the ice layer on the rail more dispersed and the crushing more uniform, avoiding the residual ice layer due to insufficient force concentration in the local area, laying the foundation for subsequent shoveling operations. After the ice layer on the rail surface is broken, as the equipment moves on the rail surface, the ice scraping mechanism at the bottom of the mounting plate 101 can be used to quickly scrape off the broken ice chips on the rail surface. The entire process does not require additional process connection, from ice crushing to complete removal in one go, greatly improving the rail de-icing efficiency. Through the synergistic effect of precise hammering and efficient scraping, this equipment can quickly remove the ice layer and broken ice residue on the rail surface, reduce the adhesion time of the ice layer on the rail, reduce the risk of train delays caused by icing, and help the railway quickly restore normal traffic order after rainy and snowy weather.

[0034] As an embodiment of the present invention, please refer to Figure 4 and Figure 5 The distance adjusting mechanism includes a stop frame 201 fixedly mounted on the end of the rotating rod 106, a rotating block 202 is rotatably provided in the stop frame 201, and a first screw 203 is fixedly mounted on the outer wall of the rotating block 202, a thread groove 204 is provided at one end of the mounting rod 107 close to the rotating rod 106, and the first screw 203 is threadedly mounted in the thread groove 204, a side plate 205 is fixedly mounted on the side wall of the mounting rod 107, and a limiting rod 206 is fixedly mounted on the outer wall of the side plate 205, and a limiting plate 207 is fixedly mounted on the side wall of the rotating rod 106, and the limiting rod 206 passes through the limiting plate 207. When the distance between the mounting rod 107 and the rotating rod 106 needs to be adjusted, the first screw 203 between the mounting rod 107 and the rotating rod 106 can be rotated. Due to the limiting effect of the limiting rod 206, the mounting rod 107 can be moved close to or away from the rotating rod 106, thereby achieving the purpose of adjusting the distance.

[0035] As an embodiment of the present invention, please refer to Figure 4 and Figure 5 A cavity 301 is provided in the hammer block 108, and a connecting pipe 302 connected to the cavity 301 is fixedly installed on the outer wall of the hammer block 108, and a sealing cover 303 is provided at the end of the connecting pipe 302. Water or sand can be added to the cavity 301 in the hammer block 108 through the connecting pipe 302. The counterweight of the hammer block 108 can be flexibly adjusted according to the thickness of the ice layer on the rail, ensuring that the ice layer can be broken while avoiding damage to the rail.

[0036] As an embodiment of the present invention, please refer to Figure 6 and Figure 9 A counterweight block 109 is also provided on the lower surface of the mounting plate 101 near one side. With the help of the counterweight block 109, the counterweight on one side of the mounting plate 101 can be increased to avoid top-heavyness and make the equipment more stable during movement.

[0037] As an embodiment of the present invention, please refer to Figure 7 and Figure 8 The ice scraping mechanism includes a vertical rod 401 fixedly mounted on the lower surface of the mounting plate 101, and a mounting frame 402 is fixedly mounted on the bottom end of the vertical rod 401. A lifting plate 403 is movably provided in the mounting frame 402, and an ice scraping module is provided on one side of the lifting plate 403 for scraping off the ice on the surface of the rail. An adjusting component is provided in the mounting frame 402 for adjusting the height of the lifting plate 403 in the mounting frame 402. The height of the lifting plate 403 can be adjusted with the help of the adjusting component, so that the ice scraping module on one side of the lifting plate 403 can be adjusted to a suitable position. When the equipment moves, the ice scraping module can be used to quickly scrape off the broken ice chips on the surface of the rail.

[0038] As an embodiment of the present invention, please refer to Figure 7 and Figure 8 The ice scraping module includes a movable plate 501 movably arranged on one side of the lifting plate 403, a movable rod 502 is fixedly installed on the outer wall of the movable plate 501 close to the lifting plate 403, and the movable rod 502 passes through the lifting plate 403, and a spring 503 is sleeved on the outer side of the movable rod 502, one end of the spring 503 is connected to the movable plate 501, and the other end of the spring 503 is connected to the lifting plate 403, and an ice scraping assembly is provided on the outer wall of the movable plate 501, and a push plate 504 is fixedly installed on the outer wall of the lifting plate 403 close to the movable plate 501, which is used to cause the ice scraping assembly to tilt when the movable plate 501 is close to the lifting plate 403. During the movement of the equipment, the ice scraping assembly can be used to scrape off the broken ice on the surface of the rail. When traveling to the junction of the rails (which can easily become an obstacle due to a slight height difference), if a jam occurs, the blocked ice scraping assembly will push the movable plate 501 closer to the lifting plate 403, thereby compressing the spring 503 on the outside of the movable rod 502. This elastic buffer design can buffer the instantaneous resistance, and then the push plate 504 on the side of the lifting plate 403 contacts the ice scraping assembly, automatically causing the ice scraping assembly to tilt upward. The entire process does not require human intervention, and can complete the continuous action of "obstruction detection-buffer adjustment-obstacle avoidance and lifting", completely avoiding the stagnation problem of traditional ice scraping devices caused by hard collisions, ensuring that the ice scraping assembly continues to move and operate uninterruptedly on the surface of the rails, greatly improving the adaptability of the equipment to the actual complex road conditions of the rails.

[0039] As an embodiment of the present invention, please refer to Figure 7 and Figure 8The ice scraping assembly includes a mounting block 601 fixedly mounted on the outer wall of one side of the movable plate 501, and a fixed shaft 602 is fixedly mounted on both sides of the mounting block 601. A rotating member 605 is rotatably sleeved on the outer side of the fixed shaft 602, and a baffle 604 is fixedly mounted on the end of the fixed shaft 602. A torsion spring 603 is also sleeved on the outer side of the fixed shaft 602, one end of the torsion spring 603 is connected to the rotating member 605, and the other end of the torsion spring 603 is connected to the baffle 604. A slot is also provided at the end of the rotating member 605, and a shovel plate 606 is inserted into the slot. The shovel plate 606 and the rotating member 605 are connected by a fixing bolt. The outer wall of the shovel plate 606 is provided with a shovel groove 607 that matches the rail. Under the action of torque, the shovel plate 606 in the rotating part 605 can apply a downward supporting force to the rail, making it convenient for the shovel plate 606 to scrape off the ice chips on the surface of the rail. When the height of the lifting plate 403 is adjusted by adjusting the assembly, the mounting block 601 will move synchronously. When the distance between the mounting block 601 and the rail is reduced, the torsion of the torsion spring 603 increases accordingly, and the supporting force of the shovel plate 606 on the rail is also enhanced accordingly. This design can flexibly adjust the ice scraping force according to the actual ice conditions (such as ice thickness, degree of ice condensation). When facing harder residual ice chips, the supporting force is increased to ensure effective scraping. When dealing with loose ice chips, the force is reduced to avoid excessive wear of the shovel plate 606 or unnecessary impact on the rail, thereby achieving precise operation adjusted on demand.

[0040] As an embodiment of the present invention, please refer to Figure 7 and Figure 8 When the second screw 703 rotates and moves, the lifting plate 403 also moves in the installation frame 402, thereby achieving the purpose of adjusting the height of the lifting plate 403, and the adjustment process is simple and convenient.

[0041] It should be noted that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
