Description

Technical Field

[0001] This application relates to the field of rail transit equipment technology, and in particular to a rail derusting and ice-breaking device for railway construction. Background Technology

[0002] The corrosion of railway track end faces directly affects the conductivity of track circuits and train operation safety, and is a critical aspect of railway construction and maintenance.

[0003] In frigid climates, the track end face is often covered with a layer of ice. This layer of ice completely covers the rusted surface, making it impossible for conventional rust removal tools to directly contact the rust layer, resulting in rust removal operations being impossible or extremely ineffective.

[0004] Currently, the common approach is to first manually break the ice or wait for it to melt, and then use hand tools or small electric equipment to polish it. This method is inefficient, labor-intensive, and it is difficult to guarantee the uniformity of cleaning. The whole process is time-consuming and labor-intensive, and there are problems such as a short working window and significant safety hazards.

[0005] Although some mechanical devices attempt to integrate rust removal and ice breaking functions, their operation mode is often a simple sequential execution, that is, first breaking the ice and then removing rust by grinding in a straight line. Although this method can improve the efficiency of rust removal to some extent, this one-way and one-time rust removal method has low cleaning efficiency and uneven effect on firmly attached layered rust surfaces.

[0033] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0034] The following describes, with reference to the accompanying drawings, a railway construction track rust removal and ice breaking device according to an embodiment of this application.

[0035] like Figure 1 As shown in the embodiment of this application, the railway construction track rust removal and ice breaking device may include a traveling mechanism 100, a moving device 200, a rust removal device 300, a speed reduction transmission device 400, an ice breaking device 500, and a linkage device 600.

[0036] The traveling mechanism 100 is mounted on the end face of the rail 800. The moving device 200 is laterally movable and mounted on the first support 101 of the traveling mechanism 100. The rust removal device 300 is mounted on the moving device 200. The ice breaking device 500 is mounted on the first support 101. The grinding end of the rust removal device 300 is connected to the power input end of the ice breaking device 500 through the speed reduction transmission device 400. The output end of the ice breaking device 500 pushes the moving device 200 back through the linkage device 600 to drive the rust removal device 300 to retract.

[0037] It should be noted that the walking mechanism 100 can be driven by human power or electricity.

[0038] For clarity, in the embodiments of this application, such as Figure 4 As shown, the rust removal device 300 includes a wire roller 310, a fixed frame 320, and a drive motor (not shown in the figure).

[0039] The wire roller 310 is rotatably mounted on the fixed frame 320 and connected to the drive motor mounted on the fixed frame 320. The fixed frame 320 is mounted on the moving device 200, and the wire roller 310 is pressed against the end face of the rail 800.

[0040] It should be noted that the drive motor drives the wire roller 310 to rotate, grinding and removing the rust on the end face of the rail 800.

[0041] For clarity, in the embodiments of this application, such as Figure 2 As shown, the moving device 200 includes a sliding seat 210, a first roller 220, a second roller 230, and an elastic reset structure 240.

[0042] The sliding seat 210 is laterally slidably mounted on the first support 101. The first roller 220 and the second roller 230 are respectively mounted on the front and rear sides of the sliding seat 210. The elastic reset structure 240 is mounted on the first support 101 and abuts against the second roller 230. The first roller 220 abuts against the linkage device 600. The rust removal device 300 is connected to the sliding seat 210 of the moving device 200.

[0043] As one possible scenario, the elastic reset structure 240 includes a mounting plate 241, a pressing plate 242, a pushing shaft 243, and a compression spring 244. The mounting plate 241 is fixed on the first bracket 101, the pushing shaft 243 is slidably disposed on the mounting plate 241, the pressing plate 242 is disposed at the end of the pushing shaft 243, and the compression spring 244 is sleeved on the pushing shaft 243. The two ends of the compression spring 244 are respectively connected to the mounting plate 241 and the pressing plate 242. The pressing plate 242 abuts against the second roller 230. When the second roller 230 pushes back following the moving device 200, it pushes the pressing plate 242, thereby causing the compression spring 244 to contract.

[0044] For clarity, in the embodiments of this application, such as Figure 4 As shown, the speed reduction transmission device 400 includes a speed reduction gear set 410, a first transmission shaft 420, a first bevel gear set 430, a second bevel gear set 440, a bushing 450, and a second transmission shaft 460.

[0045] The gears in the reduction gear set 410 are meshed together, and the drive gear is coaxially arranged with the grinding end of the rust removal device 300. The first transmission shaft 420 is rotatably mounted on the support base 201 of the moving device 200 through a bearing.

[0046] The second drive shaft 460 is rotatably mounted on the second bracket 102 of the walking mechanism 100, and the bushing 450 is splinedly fitted onto the second drive shaft 460.

[0047] One end of the first drive shaft 420 is connected to the reduction gear set 410 via the first bevel gear set 430, and the other end of the first drive shaft 420 is connected to the bushing 450 via the second bevel gear set 440.

[0048] The connecting frame 401 is slidably mounted on the second bracket 102 and connected to the moving device 200, and the bushing 450 and the first transmission shaft 420 are rotatably mounted on the connecting frame 401.

[0049] It should be noted that when the moving device 200 moves, it drives the connecting frame 401 and the rust removal device 300 to move, thereby causing the reduction gear set 410, the first bevel gear set 430, the first transmission shaft 420, the second bevel gear set 440 and the bushing 450 to move along with it, while maintaining the power transmission of the second transmission shaft 460.

[0050] For clarity, in the embodiments of this application, such as Figure 6 As shown, the ice-breaking device 500 includes a fixed cavity 510, an impact rod 520, a rolling element 530, a tension spring 540, a first connecting rod 550, and a second connecting rod 560.

[0051] The fixed cavity 510 is fixedly mounted on the first bracket 101. The impact rod 520 is slidably mounted on the passage 511 inside the fixed cavity 510. The impact rod 520 is provided with a plurality of rolling elements 530 (such as balls or rollers) that abut against the inner wall of the fixed cavity 510 on the outer side. The tension spring 540 is sleeved on the impact rod 520, and one end of the tension spring 540 is connected to the passage 511, and the other end is connected to the plate 521 on the impact rod 520.

[0052] The first connecting rod 550 is pivotally connected to the top of the impact rod 520. One end of the second connecting rod 560 is rotatably mounted on the power output end of the reduction transmission device 400, and the other end is pivotally connected to the first connecting rod 550 via the column 561.

[0053] The second connecting rod 560 is provided with a blocking head 562, and the power output end of the speed reduction transmission device 400 (i.e., the second transmission shaft 460) is provided with a lever 402 for moving the blocking head 562.

[0054] It should be noted that when the rust removal device 300 is working, it drives the lever 402 on the reduction transmission device 400 to rotate, thereby causing the lever 402 to push the blocking head 562 to rotate upward, which in turn drives the second connecting rod 560 to rotate. This causes the first connecting rod 550 to pull the impact rod 520 upward. At this time, the tension spring 540 is stretched and stores energy. After the lever 402 pushes the blocking head 562 past the highest point, the blocking head 562 loses the push of the lever 402. Under the reset action of the tension spring 540, the impact rod 520 quickly impacts the ice layer on the end face of the track, thereby breaking the ice.

[0055] For clarity, in the embodiments of this application, such as Figure 3 As shown, the linkage device 600 includes a folding fork structure 610 and a pressing structure 620.

[0056] The folding fork structure 610 with two fork heads is rotatably mounted on the first bracket 101.

[0057] The extrusion structure 620 includes a slide rod 621, an inclined plate 622, and a sleeve 623. The sleeve 623, which has a slot, is mounted on the first support 101. The inclined plate 622, which is wider at the top and narrower at the bottom, is mounted on the slide rod 621. The slide rod 621 is slidably mounted inside the sleeve 623, and the inclined plate 622 slides along the slot. The moving device 200 abuts against the inclined plate 622.

[0058] One of the forks is connected to the extension rod 501 of the ice-breaking device 500, and the other fork is connected to the slide rod 621, so that the ice-breaking device 500 drives the folding fork structure 610 to rotate, thereby driving the slide rod 621 to rise and fall, and thus causing the inclined plate 622 to squeeze the moving device 200.

[0059] It should be noted that the extension rod 501 is located on the upper part of the impact rod 520. When the impact rod 520 rises, the extension rod 501 rises along with it and pushes the corresponding shift fork head, causing the entire folding shift fork structure 610 to rotate. This causes another shift fork head to push the slide rod 621 downward, and the inclined plate 622 pushes the moving device 200, causing the moving device 200 to retract. This, in turn, drives the rust removal device 300 to retract, and under the drive of the traveling mechanism 100, a reciprocating forward rust removal and grinding operation is achieved.

[0060] Specifically, when performing ice-breaking and rust removal operations on the rail 800, relevant personnel control the traveling mechanism 100 to advance along the end face of the rail 800 and activate the rust removal device 300, causing the wire roller 310 to rotate at high speed to continuously grind and remove rust from the rail end face.

[0061] The wire roller 310 outputs power through the coaxial reduction gear set 410, and then transmits it to the first drive shaft 420, the second bevel gear set 440, the bushing 450 and the second drive shaft 460 in sequence through the first bevel gear set 430.

[0062] The lever 402 at the end of the second drive shaft 460 rotates accordingly. When the lever 402 contacts the blocking head 562, it begins to push the second connecting rod 560 to swing upward, and drives the first connecting rod 550 to pull the impact rod 520 to slide upward in the fixed cavity 510. At this time, the tension spring 540 stretches and stores energy, and the rolling element 530 reduces frictional resistance during this process.

[0063] When the lever 402 pushes the blocking head 562 past the highest point, the constraint on the blocking head 562 is released. At this time, the stretched tension spring 540 quickly resets and drives the impact rod 520 to move downward along the passage 511. Its bottom end hammers the ice layer on the end face of the track, thus breaking the ice.

[0064] In addition, during the upward energy storage process of the impact rod 520, the extension rod 501 fixed on it rises synchronously, pushing the folding fork structure 610 in the linkage device 600 to rotate accordingly, driving the slide rod 621 of the extrusion structure 620 to slide downward, causing the inclined plate 622 fixed on the slide rod 621 to move downward, and the inclined plate 622 to press the first roller 220 on the moving device 200, causing the sliding seat 210 together with the rust removal device 300 on it to move backward laterally, realizing the retraction and rust removal of the rust removal device.

[0065] When a single ice-breaking action is completed, the impact rod 520 resets, the extension rod 501 descends, the folding fork structure 610 rotates, driving the inclined plate 622 to rise. At this time, the elastic reset structure 240 pushes the second roller 230, causing the sliding seat 210 of the moving device 200 to reset and slide forward, and the rust removal device 300 also moves forward again.

[0066] The continuous forward movement of the traveling mechanism 100, combined with the periodic retraction and forward reciprocating motion of the rust removal device 300, causes the wire roller 310 to perform reciprocating grinding on the rail surface, mimicking the action of manual back-and-forth scraping. This achieves multiple grindings on the rusted areas exposed by the ice layer that have just been broken off, thereby improving the cleaning efficiency and uniformity of stubborn layered rust.

[0067] In another embodiment of this application, such as Figures 3 to 5 As shown, the track rust removal and ice breaking device for railway construction also includes a blowing device 700, which includes a wrapping cavity 710 and a blowing pipe 720.

[0068] The encapsulation cavity 710 is partially surrounded by the grinding end of the rust removal device 300 and is fitted with it with a gap to guide and collect the airflow driven by the high-speed rotation of the grinding end. The blow pipe 720 is connected to the encapsulation cavity 710 to transmit the airflow from the encapsulation cavity 710 to the blow pipe 720 to blow away the broken ice slag.

[0069] It should be noted that when the drive motor of the rust removal device 300 starts and drives the wire roller 310 to rotate at high speed for grinding and rust removal, the rotating wire roller 310 acts like an impeller or fan, stirring the surrounding air and generating a continuous airflow. The encapsulation cavity 710 guides and gathers the airflow through the gap fit with the wire roller 310, allowing the airflow to enter the internal cavity of the encapsulation cavity 710 and form a certain pressure. Then, it is sprayed outward through the blow pipe 720 connected to it. The sprayed airflow blows the broken ice slag away from the working surface, thereby keeping the subsequent grinding area clean.

[0070] As one possible scenario, the purging device 700 may also include a movable plate 730 and a pole 740.

[0071] The first support 101 is provided with a fixed plate 1011, and the fixed plate 1011 is provided with a curved groove 1012 along the forward direction. The moving plate 730 is parallel to the fixed plate 1011 and connected to the moving device 200. The moving plate 730 is provided with a long groove 731 perpendicular to the forward direction. One end of the upright 740 is connected to the purge pipe 720, and the other end passes through the long groove 731 and the curved groove 1012.

[0072] To ensure the stability of the movement of the upright 740, a limit ring is provided on the upright 740 to prevent it from tipping over. The two limit rings are located on the upper and lower sides of the moving plate 730, respectively.

[0073] It should be noted that the part connecting the purge pipe 720 to the upright 740 is a flexible part, which can follow the swing of the upright 740.

[0074] When the moving device 200 drives the rust removal device 300 to retract, the encapsulation cavity 710 retracts along with the rust removal device 300, and the moving plate 730 retracts synchronously with the moving device 200. This causes the elongated groove 731 on the moving rod to pull the upright rod 740 back. When the upright rod 740 retracts, due to the limitation of the curved groove 1012 on the fixed plate 1011, the upright rod 740 swings along the curved path of the curved groove 1012, thereby driving the blowing pipe 720 to swing, so as to blow away the ice fragments splashed in the area between the ice breaking device 500 and the front of the rust removal device 300 during the ice breaking process, reduce the contact between the wire roller 310 and the ice fragments, and prevent ice fragments from getting stuck between the rust removal device 300 and the end face of the rail 800, which would affect the accuracy of rust removal and grinding.

[0075] In another embodiment of this application, such as Figures 7 to 9 As shown, the sliding seat 210 includes a horizontal sliding seat 211 and a vertical sliding seat 212.

[0076] The horizontal slide 211 is horizontally slidably mounted on the first support 101, and the vertical slide 212 is vertically slidably mounted on the horizontal slide 211. The first support 101 is provided with a zigzag groove 1013, and the horizontal slide 211 is provided with a vertical sliding groove 2111. The side of the zigzag groove 1013 near the ice-breaking device 500 is higher than the side near the rust-removing device 300.

[0077] A sliding rod 2121 is provided on the vertical slide block 212, and the sliding rod 2121 passes through the sliding groove 2111 and the zigzag groove 1013; wherein, the first roller 220 and the second roller 230 are respectively provided on both sides of the horizontal slide block 211, and the rust removal device 300 is provided on the vertical slide block 212.

[0078] In addition, the connecting frame 401 includes a frame body 4011 and a support sleeve 4012. The frame body 4011 is slidably mounted on the second support 102, and the support sleeve 4012 is mounted on the vertical slide 212. The frame body 4011 and the support sleeve 4012 are slidably connected. The first transmission shaft 420 includes a splined main shaft 421 and a secondary shaft 422. The main shaft 421 is rotatably mounted on the support seat 201, and the secondary shaft 422 is rotatably mounted on the frame body 4011.

[0079] As one possibility, the horizontal slide 211 has a vertical T-slot 2112, and the vertical slide 212 has a sliding bar 2122 that matches the T-slot 2112.

[0080] It should be noted that when the ice-breaking device 500 starts to store energy, the linkage device 600 presses the first roller 220 of the transverse slide 211 through the inclined plate 622, triggering the slide 210 to move.

[0081] After the first roller 220 is squeezed by the inclined plate 622, it drives the transverse slide 211 to retract along the first support 101 towards the direction of the ice-breaking device 500, and the elastic reset structure 240 compresses and stores energy.

[0082] During the retraction of the horizontal slide block 211, the sliding rod 2121 of the vertical slide block 212 slides along the broken groove 1013, and the sliding groove 2111 only allows the sliding rod 2121 to move vertically. The sliding rod 2121 is forced to drive the vertical slide block 212 to slide downward along the T-shaped groove 2112 of the horizontal slide block 211.

[0083] When the vertical slide 212 descends, the rust removal device 300 moves down simultaneously, causing the wire roller 310 to adhere to the end face of the rail 800 with greater pressure. The wire roller 310 generates a stronger cutting force on the firmly attached layered rust, improving the thoroughness of rust removal.

[0084] When the vertical slide 212 descends, it drives the support sleeve 4012 of the connecting frame 401 to slide downward along the frame 4011; at the same time, the main shaft 421 of the first transmission shaft 420 moves down synchronously with the vertical slide 212, and generates axial relative extension and contraction with the secondary shaft 422 through spline engagement, ensuring that the power transmission from the main shaft 421 to the secondary shaft 422 is uninterrupted, and ensuring the continuous operation of the ice-breaking device 500.

[0085] After the ice-breaking device 500 completes the impact, the squeezing force of the linkage device 600 disappears, and the sliding seat 210 returns to its original position under the action of the elastic reset structure 240.

[0086] In summary, the railway construction track rust removal and ice breaking device according to the embodiments of this application integrates ice breaking and rust removal functions, and can continuously complete ice breaking and rust removal actions during operation, effectively solving the problem that efficient rust removal cannot be carried out directly due to ice cover in severe cold environments; the ice breaking device 500 is driven by the reduction transmission device 400 to break the ice on the track end face, and at the same time, the moving device 200 is driven by the linkage device 600 to drive the rust removal device 300 to retract, realizing the periodic reciprocating rust removal of the rust removal device 300, improving the cleaning efficiency of firmly attached layered rust surfaces.
