Description

Technical Field

[0001] This invention relates to the field of engineering vehicle technology, and in particular to a trough-shaped rail cleaning device and vehicle. Background Technology

[0002] Tram lines mostly use embedded grooved rails. Due to the special structure of the grooves in tram tracks, foreign objects such as sand and soil are very likely to accumulate and adhere to the inside of the grooved rails, even causing corrosion. Tramways and their associated engineering vehicles will also suffer damage to the rails and vehicle wheel treads due to the long-term operation of grooved rails containing foreign objects, affecting operational safety.

[0003] While current cleaning and vacuuming vehicles have track cleaning capabilities, they primarily target conventional steel rails and cannot fully meet the cleaning needs of grooved rails. There are some specialized cleaning devices for grooved rails, such as CN205617303U, which discloses a grooved rail cleaning device. This device mainly consists of a support frame and a dirt loosening mechanism and a roller brush mechanism mounted on a support. The support frame is attached to the rail vehicle via the support frame and the dirt loosening mechanism is connected to the support frame via a connecting plate. The roller brush mechanism is connected to the support frame. A vacuum cleaner hose is installed on the support frame. The torsion spring of the dirt loosening mechanism ensures its contact with the track groove, and the centrifugal force of the roller brush sweeps up the dirt, which falls within the suction range of the vacuum cleaner.

[0004] CN210368811U discloses a multi-functional sweeper with a trough rail, including a vehicle body, a cleaning device, a dust collection device, a clearance detection device, and a flushing device. The cleaning device cleans the garbage from the trough rail, and the dust collection device collects the garbage. The clearance detection device detects whether there is garbage in the cleaning area. If there is garbage, an alarm will be activated to remind the staff to deal with the garbage in time. Then the flushing device will clean the cleaning area again.

[0005] While the above solutions can clean the grooved rails to some extent, there are still blind spots in cleaning when crossing curves, resulting in unsatisfactory cleaning effects. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a trough rail cleaning device and vehicle that effectively cleans sand, soil, and other foreign objects accumulated in the special groove structure of the trough rail. Furthermore, when traversing curves, the water nozzles can be positioned radially within the track, effectively improving the cleaning efficiency of tram tracks.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0008] In a first aspect, embodiments of the present invention provide a trough rail cleaning device, comprising:

[0009] The spray cleaning device is connected to one end of the bogie via a curve steering mechanism, so that the spray nozzles of the spray cleaning device can enter the radial position of the track when passing through a curve; the spray cleaning device includes a horizontally arranged track spray pipe and a track bed spray pipe, both ends of which are connected by brackets; the track bed spray pipe is connected to a horizontal branch pipe via a vertical branch pipe, one end of which is connected to a first side wall spray pipe and the other end of which is connected to a second side wall spray pipe;

[0010] A vacuum suction device is installed at the other end of the bogie and includes a vacuum suction port for sucking up debris washed by the spray cleaning device.

[0011] As a further implementation, the curve steering mechanism is connected between the bracket and the axle box at the bottom of the bogie.

[0012] As a further implementation, the curve steering mechanism includes a mounting seat lever, a three-hole lever, and an axle box lever that are hinged in sequence, wherein the mounting seat lever is hinged to a mounting hanger on the bogie mounting beam, and the axle box lever is hinged to the axle box.

[0013] The middle part of the three-hole lever is hinged to the column on the bracket via a spraying device lever.

[0014] As a further implementation, solenoid valves are installed on the transverse branch pipes near the first side wall spray pipe and the second side wall spray pipe, respectively.

[0015] The horizontal branch pipe and the track spray pipe are respectively connected to hoses.

[0016] As a further implementation, a limiting plate is connected to the rear of the first end mounting beam of the bogie. The limiting plate has a circular hole through which the vertical branch pipe passes to support the horizontal branch pipe.

[0017] As a further implementation, the track spray pipe and the track bed spray pipe are respectively connected to the bracket via pipe clamps.

[0018] As a further implementation, the track spray pipe, the track bed spray pipe, the first side wall spray pipe, and the second side wall spray pipe are each provided with a number of spray nozzles.

[0019] Secondly, embodiments of the present invention also provide a trough rail cleaning vehicle equipped with the aforementioned trough rail cleaning device.

[0020] As a further implementation, the vehicles are coupled in pairs, and the coupled ends of the vehicles are equipped with a high-pressure jetting system.

[0021] As a further implementation, a central brush is also installed at the bottom of the vehicle, with side brushes on both sides of the central brush.

[0022] The beneficial effects of this invention are as follows:

[0023] (1) The spray cleaning device of the present invention is connected to the bogie through a curve turning mechanism, which enables the spray nozzle of the spray cleaning device to enter the radial position of the track when passing through a curve, effectively improving the cleaning efficiency of the tram track; and a vacuum suction device is installed to suck up the debris washed by the spray cleaning device. The two work together to make the cleaning of debris in the trough track more thorough.

[0024] (2) The curve steering mechanism of the present invention includes multiple levers, each lever can rotate around different round pins as axes. When the vehicle enters the curve, the vehicle body and the bogie generate relative head-shaking angle displacement. The levers keep the spray pipe and wheelset in the radial position of the track. The vertical branch pipe passes through the limiting plate, so that the horizontal branch pipe is placed on the limiting plate. When passing through the curve, the spray cleaning device can enter the radial position of the curve around the vertical branch pipe without generating a large horizontal or longitudinal displacement.

[0025] (2) The vehicle of the present invention is also equipped with a brush, which, together with a vacuum cleaning device, can achieve thorough cleaning. Attached Figure Description

Detailed Implementation

[0035] Example 1:

[0036] In a typical embodiment of the present invention, such as Figure 1 As shown, a trough-shaped rail cleaning device is presented.

[0037] Since general cleaning and suction devices and existing trough rail cleaning devices cannot thoroughly clean when passing curves, this embodiment provides a trough rail cleaning device that can effectively clean sand, soil and other foreign objects accumulated in the special groove structure of the trough rail, and can allow the water nozzle to enter the radial position of the rail when passing curves.

[0038] The cleaning device for trough rails will now be described in detail with reference to the accompanying drawings.

[0039] like Figure 1 As shown, the trough rail cleaning device includes a spray cleaning device 3 installed at one end of the bogie and a vacuum suction device installed at the other end of the bogie. The spray cleaning device 3 is connected to the bogie through the curve steering mechanism 2 so that the water nozzle enters the radial position of the track when passing through the curve, thereby improving the cleaning efficiency of the tram track.

[0040] The bogie includes a bogie body, a first end mounting beam 1, and a second end mounting beam. The first end mounting beam 1 is connected to one end of the bogie body, and the second end mounting beam is connected to the other end of the bogie body. The curve steering mechanism 2 is mounted on the first end mounting beam 1. At the same time, the curve steering mechanism 2 is also connected to the axle box 4 below the bogie body near the first end mounting beam 1. The axle box 4 is provided with a lever fulcrum seat.

[0041] like Figure 2As shown, the first end mounting beam 1 includes a box girder assembly 1.1, supporting stiffeners 1.2, mounting brackets 1.3, and limiting support plates 1.4. Multiple box girder assemblies 1.1 are spaced apart along the length of the box girder assembly 1.1 to improve the support strength of the first end mounting beam 1. The limiting support plate 1.4 is installed on one side of the box girder assembly 1.1 and is connected to the spray cleaning device 3 through the limiting support plate 1.4.

[0042] In this embodiment, the limiting plate 1.4 is an L-shaped plate. The L-shaped plate connects one end face of the limiting plate 1.4 with the box beam to form 1.1. The bottom of the other end face is equipped with a spray cleaning device 3, so that the spray cleaning device 3 is set below the end face of the first end mounting beam 1, which facilitates cleaning of the grooved rail.

[0043] The end face of the limiting plate 1.4 for mounting the spray cleaning device 3 is provided with a round hole 1.5, which is used to limit the displacement of the spray cleaning device 3, so that the spray cleaning device 3 can only rotate around the center line of the track, which makes it easier to reach the radial position of the curve when passing through the curve.

[0044] by Figure 1 With the view direction as a reference, the box girder consists of 1.1 and two mounting brackets 1.3 fixed at the bottom. The bottom of the mounting brackets 1.3 is connected to the lever fulcrum seat by bolts, and the lever fulcrum seat is connected to the curve steering mechanism 2.

[0045] As shown in Figures 4(a) and 4(b), the curve steering mechanism 2 includes a mounting base lever 2.1, a spraying device lever 2.2, a three-hole lever 2.3, and an axle box lever 2.4. The levers mentioned above are functional names. For example, the three-hole lever 2.3 indicates a lever with three mounting holes, and the mounting base lever 2.1 indicates a lever used to connect the mounting bracket 1.3.

[0046] One end of the mounting lever 2.1 is connected to the lever fulcrum seat, and the other end is connected to one end of the three-hole lever 2.3; one end of the axle box lever 2.4 is connected to the lever fulcrum seat at the end of the axle box 4, and the other end is connected to the other end of the three-hole lever 2.3; one end of the spraying device lever 2.2 is connected to the spraying and cleaning device 3, and the other end is connected to the middle position of the three-hole lever 2.3; all the above connections are made with round pins or rivet pins, so that each lever can rotate around different round pins as the axis.

[0047] like Figure 3 As shown, the spraying and cleaning device 3 includes a first side wall spray pipe 3.1, a second side wall spray pipe 3.9, a track spray pipe 3.7, a track bed spray pipe 3.8, etc. The track spray pipe 3.7 and the track bed spray pipe 3.8 are arranged horizontally with a certain distance between them; both ends of the track spray pipe 3.7 and the track bed spray pipe 3.8 are connected by corresponding brackets 3.5.

[0048] In this embodiment, a pipe clamp 3.4 is fixed to the top of each bracket 3.5, and the track spray pipe 3.7 and the track bed spray pipe 3.8 pass through the pipe clamp 3.4 to achieve position fixation. A column 3.6 is provided between two pipe clamps 3.4 of the same bracket 3.5, and the spray device lever 2.2 is connected through the column 3.6.

[0049] A transverse branch pipe 3.12 is provided on the upper side of the track bed spray pipe 3.8. One end of the transverse branch pipe 3.12 is connected to the first side wall spray pipe 3.1, and the other end is connected to the second side wall spray pipe 3.9. Solenoid valves 3.10 are installed on both the transverse branch pipe 3.12 and the second side wall spray pipe 3.9. The transverse branch pipe 3.12 is connected to the track bed spray pipe 3.8 via a vertical branch pipe 3.11. Furthermore, the transverse branch pipe 3.12 is connected to an L-shaped first flexible hose 3.2, and the track spray pipe 3.7 is connected to an L-shaped second flexible hose 3.3.

[0050] The vertical branch pipe 3.11 passes through the circular hole 1.5 of the limiting plate 1.4, so that the horizontal branch pipe 3.12 is set on the upper side of the limiting plate 1.4. When passing through the curve, the spray cleaning device 3 can enter the radial position of the curve around the vertical branch pipe 3.11 without producing a large horizontal or vertical displacement.

[0051] The first hose 3.2 and the second hose 3.3 are used to connect the water supply device. The track spray pipe 3.7, the track bed spray pipe 3.8, the first side wall spray pipe 3.1 and the second side wall spray pipe 3.9 are all equipped with several spray nozzles. The number of spray nozzles is set according to the cleaning requirements of different locations.

[0052] The vacuum suction device is connected to the second end mounting beam 5 via a mounting beam. The vacuum suction device includes a vacuum suction port 6 and a vacuum negative pressure device connected to the vacuum suction port 6. For example... Figure 6 As shown, the vacuum suction port 6 is L-shaped and has a certain curvature. Under the action of the vacuum negative pressure device, the vacuum suction port 6 can effectively suction and clean the trough-shaped track.

[0053] It should be noted that the vacuum negative pressure equipment is existing equipment and will not be described in detail here.

[0054] When the vehicle enters a curved track, because the bogie's primary suspension uses rubber springs, which have relatively low lateral and longitudinal positioning stiffness, the wheelset at the first end will sway to a radial position perpendicular to the track's centerline as the curve progresses. At this time, the axle boxes 4 on both sides of the first end will no longer be parallel to the vehicle's centerline, thus also driving the curve steering mechanism 2. Through lever transmission, this will also sway the spray cleaning device 3 to a position close to the curve's radial direction. This avoids the situation in conventional cleaning vehicles where the cleaning device is fixed to the vehicle body, resulting in a head-down angle where the vehicle's centerline is not parallel to the track after entering a small curved track, making it impossible for the cleaning device to effectively clean the track surface on the curve.

[0055] The spray cleaning device 3 and its bogie in this embodiment are suitable for small-radius curve tracks in various subways and stations, and can effectively clean the track surface of curved tracks. At the same time, the two ends of the bogie are equipped with mounting beams and vacuum suction ports 6. The vacuum suction ports 6 are connected to the equipment on the vehicle, which can suck away stones and other debris washed away at the first end, ensuring the cleaning effect of the trough track.

[0056] Example 2:

[0057] This embodiment provides a trough rail cleaning vehicle, equipped with the trough rail cleaning device described in Embodiment 1, such as... Figure 7 As shown, the vehicles are coupled in pairs. The outer ends of the two vehicles are equipped with rotating brushes, and the outer bogies are equipped with grooved rail cleaning devices. The coupling ends are equipped with high-pressure jet cleaning systems.

[0058] The high-pressure jet cleaning system is an existing device used to blow away large pieces of residual dirt and quickly dry the track, preventing water accumulation from reducing the track's friction.

[0059] Two sets of side brushes 7.1 and one set of center brushes 7.2 are installed in the middle of the vehicle. The two sets of side brushes 7.1 are arranged on the left and right. The side brushes 7.1 are used to clean the outer side of the track bed, and the center brushes 7.2 are used to clean the inner side of the track bed. Each set of side brushes 7.1 is equipped with two suction pipes, and each set of center brushes 7.2 is equipped with three suction pipes and one rectangular suction port. The side brushes 7.1 clean the outer side of the track, and the center brushes 7.2 clean the track bed. At the same time, vacuum negative pressure suction technology is used to suck foreign objects and dust into the waste bin on the vehicle.

[0060] The vehicle in this embodiment has functions such as sweeping, water spraying, vacuuming, and high-pressure air drying.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
