Description

Technical Field

[0001] The present application relates to the technical field of track cleaning, and in particular, to a cleaning system and an operating method of a track cleaning vehicle. Background Art

[0002] At present, the top of the carriages of coal transport trains used in domestic railway coal transport lines all adopt an open roof structure. When coal transport trains enter and exit tunnels and when vehicles meet or pass each other in tunnels, the air turbulence formed will roll the coal powder and some coal lumps in the carriages out of the carriages and scatter them on the roadbed surface, drainage ditches and shelters in the tunnels. The coal powder brought up by the trains will seriously affect the train driver's vision. When the coal powder and coal lumps are deposited thickly, they will bury the rails, sleepers, spike fasteners and electrical equipment, making them impossible to repair, endangering the driving safety of the trains.

[0003] The sweeping and suction working device of the railway ballast bed suction vehicle adopts an operation mode combining double roller brush sweeping and vacuum negative pressure suction. This working device can only clean the coal powder scattered within the range of the sleepers. The cleaning range is limited and cannot cover the entire ballast bed surface.

[0004] Therefore, the traditional railway roadbed suction truck can only clean the sewage within the range of the rail sleepers, which is a technical problem that technical personnel in this field urgently need to solve.

[0005] The above information disclosed in the background section is only for enhancing understanding of the background of the present application and therefore it may contain information that does not form the prior art known to a person of ordinary skill in the art. Summary of the invention

[0006] The embodiments of the present application provide a cleaning system and an operating method of a track cleaning vehicle to solve the technical problem that a conventional railway track bed suction vehicle can only clean within the range of the track sleepers.

[0007] According to a first aspect of an embodiment of the present application, a cleaning system for a track cleaning vehicle is provided, comprising:

[0008] A cleaning component, used for cleaning the track;

[0009] A mounting assembly, wherein the upper end of the mounting assembly is used to be fixed to the rail cleaning vehicle, and the lower end is fixed to the cleaning assembly, and the mounting assembly is used to extend and retract in the lateral direction to drive the cleaning assembly to extend and retract in the lateral direction;

[0010] Among them, when the installation component is extended to a preset extended position in the lateral direction, the cleaning component at least partially exceeds the limit of the track cleaning vehicle to clean the track; when the installation component is retracted to a preset retracted position in the lateral direction, the cleaning system meets the limit requirements of the track cleaning vehicle.

[0011] According to a second aspect of an embodiment of the present application, there is provided an operation method of a cleaning system of a track cleaning vehicle, comprising the steps of cleaning the track bed outside the track; the steps of cleaning the track bed outside the track specifically include the following steps:

[0012] The cleaning component extends in a lateral direction until it reaches a preset extended position;

[0013] The cleaning component descends in the vertical direction until it reaches a preset cleaning operation height;

[0014] The suction device and the roller brush device are working;

[0015] When it is necessary to stop the sewage suction work, the following steps are also included:

[0016] The suction device and the roller brush device stop working;

[0017] The cleaning component rises in the vertical direction until it reaches a preset storage height;

[0018] The dirt-cleaning device is retracted in the lateral direction until it is retracted to a preset retracted position.

[0019] The embodiment of the present application adopts the above technical solution, which has the following technical effects:

[0020] The cleaning component is installed by the installation component, and the extension and retraction of the cleaning component in the lateral direction is realized by the extension and retraction of the installation component in the lateral direction. In this way, when the installation component is retracted in the lateral direction to a preset retracted position, the cleaning system meets the limit requirements of the track cleaning vehicle. At this time, the track cleaning vehicle that meets the limit requirements can travel on the track, thereby realizing the need for the track cleaning vehicle to reach and leave the working area. When the track needs to be cleaned, when the installation component is extended in the lateral direction to a preset extended position, the cleaning component at least partially exceeds the limit of the track cleaning vehicle, and the track is cleaned. At this time, the cleaning component is realized to clean the part of the track that exceeds the limit range of the track cleaning vehicle, such as the roadbed. The cleaning system of the embodiment of the present application realizes the extension and retraction of the cleaning component in the lateral direction through the installation component, so that at least a part of the cleaning component can exceed the limit of the track cleaning vehicle, and can clean the part of the track that exceeds the limit of the track cleaning vehicle.

[0032] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0033] In the background technology, the width of the sweeping and suction working device of the railway roadbed suction vehicle in the lateral direction is limited by the railway's limit requirements for locomotives and vehicles, resulting in the sweeping and suction working device being able to only clean the coal powder scattered within the sleeper range, and being unable to clean the entire roadbed surface outside the locomotive limit range.

[0034] Embodiment 1

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cleaning system of the rail cleaning vehicle of the embodiment of the present application includes:

[0036] A cleaning assembly 200, for cleaning the track;

[0037] The mounting assembly 300, the upper end of which is used to be fixed to the rail cleaning vehicle, and the lower end of which is fixed to the cleaning assembly 200, and the mounting assembly 300 is used to extend and retract in the lateral direction to drive the cleaning assembly 200 to extend and retract in the lateral direction;

[0038] Among them, when the installation component 300 is extended to a preset extended position in the lateral direction, the cleaning component 200 at least partially exceeds the limit of the track cleaning vehicle to clean the track; when the installation component 300 is retracted to a preset retracted position in the lateral direction, the cleaning system meets the limit requirements of the track cleaning vehicle.

[0039] The cleaning system of the track cleaning vehicle of the embodiment of the present application is installed by installing the cleaning component through the installation component, and the cleaning component is extended in the lateral direction by the extension and contraction of the installation component in the lateral direction. In this way, when the installation component is retracted in the lateral direction to the preset retracted position, the cleaning system meets the limit requirements of the track cleaning vehicle. At this time, the track cleaning vehicle that meets the limit requirements can travel on the track, thereby realizing the need for the track cleaning vehicle to reach and leave the working area. When the track needs to be cleaned, when the installation component is extended in the lateral direction to the preset extended position, the cleaning component at least partially exceeds the limit of the track cleaning vehicle, and the track is cleaned. At this time, the cleaning component is realized to clean the part of the track that exceeds the limit range of the track cleaning vehicle, such as the roadbed. The cleaning system of the embodiment of the present application realizes the extension and contraction of the cleaning component in the lateral direction through the installation component, so that at least a part of the cleaning component can exceed the limit of the track cleaning vehicle, and can clean the part of the track that exceeds the limit of the track cleaning vehicle.

[0040] Specifically, the cleaning system also includes:

[0041] A fixing member 100, used for fixing to the body of the track cleaning vehicle;

[0042] The upper end of the mounting assembly 300 is fixed to the fixing member 100 .

[0043] Specifically, Figure 1 and Figure 2As shown, the fixing member is a fixed beam with a rectangular frame cross section, and the two beam plates where the long sides of the rectangular frame of the fixed beam are located are arranged above and below, and the installation component is fixed to the lower beam plate of the fixed beam.

[0044] The two beams where the long sides of the rectangular frame are located are arranged up and down, so that the lower beam of the fixing part is used to fix with the body of the rail cleaning vehicle, the fixing area is larger, and the fixing is more convenient and stable; the lower beam of the fixed beam fixes the installation component, the fixing area is larger, and the fixing is more convenient and stable.

[0045] During implementation, the mounting assembly is also used to extend in the vertical direction to drive the cleaning assembly to move downward to a preset cleaning operation height and to retract and reset;

[0046] When the mounting assembly is extended in the lateral direction to a preset extended position and the cleaning assembly moves downward to a preset cleaning operation height, the cleaning assembly at least partially exceeds the limit of the track cleaning vehicle to clean the track bed outside the track;

[0047] When the mounting assembly is located at a preset retracted position and the cleaning assembly moves downward to a preset cleaning operation height, the cleaning assembly can clean the track.

[0048] In this way, the coal ash between the two rails in the track can be cleaned, and the coal ash on the roadbed outside the track can also be cleaned, so that the scope of the cleaning operation of the cleaning system can be changed, with better adaptability and strong versatility.

[0049] In implementation, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cleaning assembly includes a cleaning cover and a cleaning body installed in the cleaning cover; the installation assembly includes a transverse subassembly, and the transverse subassembly includes:

[0050] The transverse guide groove 311 is arranged on the upper cover plate of the cleaning cover, and the guide direction is the transverse direction;

[0051] The transverse plate 312 is fixed relative to the track cleaning vehicle in the transverse direction, and specifically, is fixed relative to the fixing member 100 in the transverse direction, and the edge of the transverse plate 312 serves as a transverse guide rail and is slidably matched with the transverse guide groove 311;

[0052] The transverse driving device 313 has two ends respectively fixed to the transverse plate 312 and the cleaning cover, the telescopic direction of the transverse driving device 313 is consistent with the guiding direction of the transverse guide groove 311, and the telescopic movement of the transverse driving device 313 drives the cleaning component to telescope in the transverse direction.

[0053] In this way, the transverse guide groove, the transverse plate and the transverse drive device cooperate to conveniently realize the extension and retraction of the transverse drive device to drive the cleaning component to extend and retract in the transverse direction; at the same time, the structure is simple and easy to implement.

[0054] Specifically, there are two transverse guide grooves 311 and the notches of the two transverse guide grooves are arranged opposite to each other.

[0055] In this way, the two opposite edges of the transverse moving plate are respectively slidably matched with the two transverse moving guide grooves, so that the relative sliding in the transverse direction is smoother and the force is more balanced.

[0056] In implementation, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the installation assembly also includes a lifting subassembly; the lifting subassembly includes:

[0057] A fixing sleeve 321, the upper end of which is used to be fixed to the lower surface of the track cleaning vehicle. Specifically, the upper end of the fixing sleeve 321 is fixed to the lower surface of the fixing member 100;

[0058] A lifting base 322 is fixed on the upper surface of the transverse plate 312 and sleeved on the inner surface of the fixed sleeve 321;

[0059] The lifting drive device 323 has two ends fixed to the transverse plate 312 and the fixed sleeve 321 respectively, and the longitudinal extension and retraction of the lifting drive device 323 drives the transverse plate 312 and the cleaning assembly 200 to rise and fall.

[0060] The lifting subassembly can drive the cleaning assembly to rise and fall to meet the height requirements of the cleaning work. Through the cooperation of the fixed sleeve, the lifting base and the lifting drive device, the longitudinal extension of the lifting drive device drives the lifting of the transverse plate and the cleaning assembly; at the same time, the structure is simple and easy to implement.

[0061] In implementation, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the cleaning body comprises:

[0062] A suction device 210 and a rolling brush device 220 are arranged in front and back, and the rolling brush device 220 rolls in the direction of the suction device 210 and upwards;

[0063] Wherein, when the cleaning system moves with the rail cleaning vehicle, the suction device 210 is located in front of the roller brush device 220 .

[0064] The operation mode combines the roller brush cleaning of the roller brush device with the vacuum negative pressure suction of the suction device, and the cleaning effect is good and the efficiency is high. The suction device and the roller brush device are arranged front and back, and the roller brush device is in the direction of the suction device and rolls upward, so that dirt such as coal ash is rolled up by the roller brush device, and the suction device sucks the dirt that is rolled up, and the cleaning efficiency is high. The coal dust and dust on the entire track bed surface are swept up and immediately sucked into the dust removal device of the track cleaning vehicle to solve the pollution problem of coal dust and dust on the track bed and ensure the safety of railway electrical equipment and driving.

[0065] In implementation, the suction device 210 can be adjusted forward and backward relative to the roller brush device 220 in the forward and backward direction.

[0066] After the roller brush of the roller brush device is worn, the suction device can be timely adjusted toward the roller brush device to maintain the distance between the suction device and the roller brush of the roller brush device.

[0067] The structure of the suction device is described below. In order to achieve that the suction device can be adjusted forward and backward relative to the roller brush device in the forward and backward direction. Figure 5 As shown, the suction device 210 includes:

[0068] Suction hood 211;

[0069] A connecting pipe 212, wherein the connecting pipe 212 is fixed to an upper cover opening of the suction cover 211 to form a suction channel;

[0070] A slide seat 213, the slide seat 213 is fixed on the outside of the connecting pipe 212, the slide seat 213 has a front and rear guide groove, and the guiding direction of the front and rear guide groove is the front and rear direction;

[0071] The suction hood guide frame 214 is fixed at the opening of the upper cover plate of the cleaning hood body. The suction hood guide frame has front and rear guide rails 214-1. The front and rear guide rails 214-1 cooperate with the front and rear guide grooves to enable the suction hood 211 and the connecting pipe 212 fixed together to move forward and backward relative to the roller brush device.

[0072] In this way, the suction hood and the connecting pipe fixed together can be adjusted forward and backward relative to the roller brush device. When the roller brush of the roller brush device is worn, the suction device can be adjusted in time to be close to the roller brush device to maintain the distance between the suction device and the roller brush of the roller brush device, thereby ensuring the best cleaning effect.

[0073] In implementation, such as Figure 5 As shown, the suction device also includes:

[0074] An adjusting screw hole, wherein the adjusting screw hole is arranged at a frame edge of the suction cover guide frame, and the screwing-in and screwing-out direction of the adjusting screw hole is consistent with the guiding direction of the front and rear guide grooves;

[0075] The adjusting bolt 215 is inserted into the adjusting screw hole to support the sliding seat 213; the adjusting bolt 215 enables the suction hood 211 and the connecting pipe 212 fixed together to be adjusted forward and backward relative to the roller brush device in the forward and backward direction.

[0076] By adjusting the screw hole and the adjusting bolt, fine adjustment of the suction hood relative to the front-rear direction of the roller brush device is achieved.

[0077] In implementation, such as Figure 5 As shown, the suction hood 211 includes an inner suction hood 211-1 and an outer suction hood 211-2, the upper end of the outer suction hood 211-2 is fixed to the outside of the lower end of the inner suction hood 211-1, and a preset gap is maintained between the upper end of the outer suction hood 211-2 and the lower end of the inner suction hood 211-1, and the preset gap is used to supply air to the suction hood.

[0078] That is, the suction hood adopts a double-layer air supply structure, and the suction hood can be supplied with air through a preset gap to prevent dirt such as coal powder from accumulating and blocking the hood opening, so that the suction efficiency can be maintained at a high level.

[0079] Specifically, the central plane of the suction hood forms a preset angle with the vertical direction, and the value range of the preset angle is greater than or equal to 5° and less than or equal to 30°, so that the coal powder swept by the roller brush can more easily enter the suction hood.

[0080] Specifically, the hood opening in the suction hood adopts the form of a round sky and a square earth, the upper hood opening of the suction inner hood adopts a round hood opening, the lower hood opening of the suction inner hood, and the upper hood opening and the lower hood opening of the suction outer hood adopt square hood openings.

[0081] The suction hood with such a structure has high suction efficiency.

[0082] In implementation, such as Figure 1 and Figure 2 As shown, there are two cleaning components 200 and two mounting components 300, and the cleaning components correspond to the mounting components one by one;

[0083] When the two installation components 300 are extended in the lateral direction to a preset extended position, the two cleaning components 200 are separated in the lateral direction, and each exceeds the limit of the track cleaning vehicle to clean the track; when the installation components 300 are retracted in the lateral direction to a preset retracted position, the two cleaning components 200 are adjacent to each other in the lateral direction, and the cleaning system meets the limit requirements of the track cleaning vehicle.

[0084] Two cleaning components are installed under the same fixing part. The two cleaning components can be lifted, moved horizontally and cleaned at the same time, and can clean the sleepers and the ballast on both sides of the track. The structure is symmetrical, the force is relatively balanced, and the cleaning efficiency is also high. The left cleaning component can move horizontally to the left, and the right cleaning component can move horizontally to the right. It can clean coal within the sleeper range and the ballast outside the sleeper range, covering the entire ballast surface and covering a wide range.

[0085] Specifically, the two cleaning components 200 of the same fixing member are symmetrically arranged.

[0086] In implementation, such as Figure 6 As shown, the roller brush device 220 includes:

[0087] Roller brush shaft 221;

[0088] Two bearings and two bearing seats 222, the two bearing seats are installed at both ends of the roller brush shaft through two bearings; wherein the bearing seats are fixed to the cleaning cover;

[0089] The roller brush mounting seat 223 is fixed to the portion of the roller brush shaft between the two bearing seats; wherein the outer diameter of the roller brush mounting seat is greater than or equal to the outer diameter of the bearing seat,

[0090] A plurality of roller brushes 224, wherein the roller brushes 224 are fixed to the roller brush mounting seat 223, and the bearing seat 223 is located inside the roller brush 224;

[0091] The sprocket 225 of the roller brush device is fixed to one end of the roller brush shaft and is located outside the bearing seat at the same end;

[0092] Wherein, the sprocket of the roller brush device drives the roller brush shaft to rotate, thereby driving the roller brush to rotate.

[0093] The sprocket, roller brush shaft, roller brush mounting seat and roller brush of the roller brush device are fixed together, and two bearing seats are fixed to the cleaning cover body and are rotatably connected through bearings. In this way, the sprocket of the roller brush device rotates, driving the roller brush shaft to rotate, and then driving the roller brush to rotate. The bearing seat of the roller brush shaft is located inside the roller brush, so that the roller brush has a larger lateral coverage range.

[0094] Specifically, the groove in the roller brush mounting seat 223 and the position where the roller brush shaft 221 is exposed are notches for weight reduction, and the roller brush mounting seat 223 is an integral body.

[0095] In implementation, the two bearing seats are respectively mounted on two opposite side plates of the cleaning cover, and the sprocket of the roller brush device is exposed from one side plate of the cleaning cover;

[0096] like Figure 4As shown, the roller brush device also includes a roller brush driving device 226, which is fixed in the cleaning cover and the sprocket of the roller brush driving device and the sprocket of the roller brush device are exposed from the same side of the cleaning cover; wherein the sprocket of the roller brush driving device and the sprocket of the roller brush device are driven by a chain.

[0097] The chain realizes the synchronous transmission of the sprocket of the roller brush driving device and the sprocket of the roller brush device, thereby realizing the rotation of the roller brush.

[0098] Specifically, the roller brush driving device adopts a hydraulic motor.

[0099] Specifically, the two opposite side plates on which the two bearing seats are installed in the cleaning cover are support plates, and the strength and hardness of the support plates need to meet the requirements for supporting the roller brush device.

[0100] Specifically, the rear side plate of the cleaning cover is provided with an inspection port for inspecting the roller brush device and facilitating replacement of the roller brush; the front side plate of the roller cleaning cover is fixedly connected to the suction cover.

[0101] Specifically, detachable rubber plates are arranged around the bottom of the cleaning cover, and the rubber plates increase the sealing performance to prevent coal powder from splashing outwards during operation.

[0102] The working principle of the cleaning system of the rail cleaning vehicle in the above embodiment is: when performing sweeping and suction cleaning operations within the range of the sleeper, the cleaning assembly is lowered to a height suitable for the cleaning work by adjusting the lifting subassembly; when performing sweeping and suction cleaning operations within the sleeper and the ballast bed, the cleaning assembly is lowered to a height suitable for the cleaning work by adjusting the lifting subassembly, and then the cleaning assembly is moved laterally to the working position by adjusting the transverse subassembly. After adjusting the working position, the hydraulic motor is started to drive the roller brush device to rotate, and the roller brush sweeps up the coal powder and dust and other garbage pollutants on the ballast bed into the suction hood; at the same time, the suction fan rotates at the hood opening to form suction (suction flow) to suck the corresponding garbage pollutants into the suction hood, and then through the connecting pipe, it is filtered by the dust removal system and then falls into the conveyor belt through the unloader, and the materials are transported away by the conveyor belt.
