Description

Technical Field

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

[0002] Rails are mainly used on railways, and together with switches, trains can continue to move forward without turning. Usually, railway tracks are composed of two parallel steel rails, which are fixed on sleepers, and ballast is under the sleepers. In addition, the geometric shape, relative position and basic dimensions of each part of the railway track, such as gauge, level, front and rear height and track direction, are very important. They work together to guide the movement of locomotives and vehicles and bear various loads of locomotives and vehicles.

[0003] The rails are I-shaped structures. When the rails are laid, two adjacent rails are fixedly connected by rail connectors, and a rail seam is formed between the two rail ends. Rust in the rail seam usually needs to be polished to ensure the safety and smooth operation of the railway line. The presence of rust may affect the flatness and service life of the rails, and if not handled in time, it may also cause increased noise and vibration during train operation.

[0004] For example, a Chinese invention patent with authorization announcement number CN113026452B provides a cleaning and maintenance device for subway rail transit, which cleans and removes protruding rust or other debris by clamping plates to both sides of the rails. However, the device cannot automatically grind and remove rust from the end faces of the rail joints, and since the internal space of the rail joints is small, there is no effective grinding and rust removal method, and manual operation is time-consuming and labor-intensive. Summary of the invention

[0005] The invention provides a cleaning and maintenance device for rail transit, so as to solve the problem that the existing rail cleaning device cannot perform grinding and rust removal treatment on the end surface of the rail.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figures 1 to 11 As shown, a rail transit cleaning and maintenance device provided by an embodiment of the present invention includes two grinding mechanisms, which are arranged in sequence along a first direction. Each grinding mechanism includes an upper bracket 320, a lower bracket 330, a grinding rope 370, an upper slider 363, a lower slider 366, a first drive assembly, a second drive assembly, and a positioning assembly.

[0034] The upper bracket 320 is disposed above the rail 100, a first slide rail 321 is provided on one side of the upper bracket 320, and the upper slider 363 is slidably disposed in the first slide rail 321.

The first driving assembly is used to drive the upper slider 363 and the lower slider 366 to slide.

[0035] The upper end of the grinding rope 370 is arranged on the upper slider 363, and the lower end of the grinding rope 370 is arranged on the lower slider 366. The second driving assembly is used to drive the grinding rope 370 to move up and down. The positioning assembly includes a positioning rod 352, and the positioning rod 352 is slidably arranged on the upper bracket 320 along the second direction. The first direction and the second direction are both horizontal directions, the first direction is perpendicular to the second direction, and the second direction is parallel to the end face of the rail 100. The positioning rod 352 is arranged vertically, and the positioning rod 352 and the grinding rope 370 are against each other.

[0036] In this embodiment, the rail 100 includes an upper section 101, a middle section 102 and a lower section 103 which are sequentially arranged from top to bottom. The upper bracket 320 is arranged on the upper section 101, the lower bracket 330 is arranged on the lower section 103, the first slide rail 321 is arranged along the circumference of the upper section 101, and the second slide rail 331 is arranged along the circumference of the lower section 103.

[0037] The upper slider 363 slides in the first slide rail 321 , and the lower slider 366 slides in the second slide rail 331 , and drives the grinding rope 370 to move on the end surface of the rail 100 to grind the end surface of the rail 100 .

[0038] In this embodiment, a limit block 340 is fixedly provided on the upper bracket 320, and a first rack 351 is fixedly provided on the upper end of the positioning rod 352, and the first rack 351 is arranged along the second direction. The positioning assembly also includes a first motor 341, which is fixedly provided on the limit block 340, and the output shaft of the first motor 341 is fixedly connected to the first gear 342, the axis of the first gear 342 is arranged vertically, and the first gear 342 and the first rack 351 are meshed. The first motor 341 is started to drive the first gear 342 to rotate, and since the first gear 342 and the first rack 351 are meshed, the first rack 351 starts to move along the second direction relative to the first gear 342, the first rack 351 drives the positioning rod 352 to move, and the positioning rod 352 drives the grinding rope 370 to move synchronously.

[0039] In this embodiment, along the second direction, the width of the middle section 102 of the rail 100 is the distance moved by the first rack 351. The positioning rod 352 limits the grinding rope 370. When the positioning rod 352 moves, it does not exceed the width range of the middle section 102 of the rail 100, so as to ensure that the grinding rope 370 grinds all the end faces of the rail 100 while preventing the grinding rope 370 from cutting the track connector 200.

[0040] In this embodiment, a second rack is fixedly arranged in the first slide rail 321, and the second rack is arranged along the extension direction of the first slide rail 321. A third rack is fixedly arranged in the second slide rail 331, and the third rack is arranged along the extension direction of the second slide rail 331. The first driving assembly includes two second motors 361 and two second gears 362, wherein one second motor 361 is fixedly arranged on the upper slider 363, and the other second motor 361 is fixedly arranged on the lower slider 366, and the output shaft of each second motor 361 is fixedly connected to a second gear 362. The second gear 362 on the upper side meshes with the second rack, and the second gear 362 on the lower side meshes with the third rack. When the second motor 361 is started, the second motor 361 drives the second gear 362 to rotate, thereby driving the upper slider 363 to slide in the first slide rail 321, and the lower slider 366 to slide in the second slide rail 331.

[0041] In this embodiment, the second driving assembly includes two third motors 364 and two winches 365. One of the third motors 364 is fixedly disposed on the upper slider 363, and the other third motor 364 is fixedly disposed on the lower slider 366. The output shaft of each third motor 364 is fixedly connected to a winch 365. The upper and lower ends of the grinding rope 370 are respectively wound around the two winches 365. When the third motor 364 is started, the third motor 364 drives the winch 365 to rotate, and the upper and lower winches 365 cooperate to reciprocate the grinding rope 370, so that the grinding rope 370 grinds and removes rust on the end surface of the rail 100.

[0042] In this embodiment, each capstan 365 is provided with a fixing hole 3651, and the grinding rope 370 passes through the fixing hole 3651 and is fixed to the capstan 365. During installation, the upper end of the grinding rope 370 is first fixed to the fixing hole 3651 of the upper capstan 365, and the upper end of the grinding rope 370 is wound around the upper capstan 365, and then the grinding rope 370 is passed through the track seam, and then the lower end of the grinding rope 370 is fixed to the fixing hole 3651 of the lower capstan 365, and the lower end of the grinding rope 370 is wound around the lower capstan 365.

[0043] In this embodiment, a plurality of positioning buckles 353 are fixedly provided on the positioning rod 352, and the plurality of positioning buckles 353 are distributed in sequence along the vertical direction. A positioning groove is provided on each positioning buckle 353, and the positioning groove is arc-shaped, with the arc-shaped opening facing the end face of the rail 100. The grinding rope 370 passes through the plurality of positioning grooves in sequence. The plurality of positioning grooves make the grinding rope 370 and the end face of the rail 100 closely attached to ensure that the end face of the rail 100 can be ground.

[0044] What is different from this embodiment is that a limiting groove is provided on the positioning rod 352, and a plurality of positioning buckles 353 are slidably disposed in the limiting groove, and each positioning buckle 353 can be fixed in the limiting groove by a movable bolt. At this time, the spacing between the plurality of positioning buckles 353 is adjustable to adapt to tracks of different sizes.

[0045] In this embodiment, the rail transit cleaning and maintenance equipment further includes two fixing bolts 332 , which are vertically arranged and used to fix the upper bracket 320 and the lower bracket 330 together.

[0046] In this embodiment, the rail transit cleaning and maintenance equipment further includes a connecting mechanism, which includes a limit plate 310, which is arranged in a direction perpendicular to the second direction, and is arranged above two upper brackets 320, and the limit plate 310 and the upper bracket 320 are connected by bolts. First, the two grinding mechanisms are installed in the track gap between the two rails 100, each grinding mechanism corresponds to the end face of a rail 100, and then the two grinding mechanisms are connected together using the limit plate 310. The two grinding mechanisms can start working at the same time, the overall time required is less, and the work efficiency is higher.

[0047] Working process: Two adjacent rails 100 are fixedly connected by rail connectors 200, and a rail gap is formed between the end faces of the two rails 100. First, two grinding mechanisms are installed in the rail gap between the two rails 100, each grinding mechanism corresponds to an end face of the rail 100, and then the two grinding mechanisms are connected together using a limit plate 310.

[0048] The second motor 361 is started, and the second motor 361 drives the second gear 362 to rotate, thereby driving the upper slider 363 to slide in the first slide rail 321, and the lower slider 366 to slide in the second slide rail 331. At the same time, the third motor 364 is started, and the third motor 364 drives the capstan 365 to rotate. The upper and lower capstans 365 cooperate to reciprocate and release the grinding rope 370, so that the grinding rope 370 grinds and removes rust from the end surface of the rail 100. At the same time, the first motor 341 is started, and the first motor 341 drives the first gear 342 to rotate. Since the first gear 342 and the first rack 351 are meshed, the first rack 351 starts to move along the second direction relative to the first gear 342, and the first rack 351 drives the positioning rod 352 to move synchronously.

[0049] The moving length of the first rack 351 and the positioning rod 352 is the width of the middle section 102 of the rail 100 along the second direction. The positioning rod 352 does not exceed the width of the middle section 102 of the rail 100 when moving, so as to ensure that the grinding rope 370 grinds all the end surfaces of the rail 100 while preventing the grinding rope 370 from cutting the rail connector 200.

[0050] like Figure 7 and Fig.11 The shapes of the grinding rope 370 when the upper slider 363 and the lower slider 366 are in different positions are shown.

[0051] When the two grinding mechanisms are working, the two grinding ropes 370 are arranged in sequence along the second direction, so that the two grinding ropes 370 are staggered to prevent the two grinding ropes 370 from interfering with each other during work, and can adapt to narrower track gaps.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
