Description

Technical Field

[0001] The present invention relates to the technical field of high-speed train equipment, and more specifically, to a high-speed train cleaning machine. Background Art

[0002] When high-speed trains are running, pollutants such as dust, carbon powder, iron filings and shellac in the air are easily attached to the surface of the trains, and after long-term accumulation, yellow spots and stubborn dirt are formed on the surface of the trains. Therefore, the surface of the trains needs to be cleaned regularly to ensure the cleanliness of the surface of the trains. Most of the existing high-speed train cleaning methods are to slowly drive the high-speed train into the cleaning warehouse, and then use the high-speed train cleaning machine to clean the surface of the high-speed train in the cleaning warehouse.

[0003] Existing high-speed train cleaning machines often use a choice of brushing or high-pressure washing, but the train end face is an irregular curved surface, and a single brushing or high-pressure washing cannot effectively remove pollutants. In addition, when the high-speed train cleaning machine cleans various pollutants on the surface of the train, the subsequent high-speed trains that need to be cleaned can only stop and wait, which greatly reduces the cleaning efficiency of the train.

[0004] Therefore, how to enhance the cleaning effect of trains and improve the cleaning efficiency of trains is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0030] Compared with the above background technology, when a train enters the car wash garage, it does not need to stop and wait, but only needs to move forward slowly, and the two car washers can move to the two end faces of the train respectively along the travel direction of the train. Therefore, the gantry and high-pressure washing running device of a car wash machine move forward in the travel direction of the train, and at the same time, the brush shaft in the brush washing device installed on the gantry brushes the side of the train until the car wash machine moves to the front end face of the train, and the brush shaft moving device controls the spatial movement of the brush shaft, and cooperates with the movement of the gantry, so that the bristles on the brush shaft effectively fit the end face of the train for brushing.

Therefore, a combination of scrubbing and high-pressure washing is used to clean the end face and side of the train, and contour brushing and contour washing of the end face of the train are performed to clean the entire area of ​​the end face, avoiding the problem that the end face of the train is difficult to clean due to the irregular curved surface, and solving the problem that pollutants on the side of the train are difficult to clean, thereby enhancing the cleaning effect of the train. In addition, when cleaning the train, there is no need to stop and wait.

[0049] The core of the present invention is to provide a high-speed train cleaning machine, which can enhance the cleaning effect of the train and improve the cleaning efficiency of the train.

[0050] It should be noted that the "longitudinal" mentioned below refers to the direction of travel of the train, and the "lateral" refers to the direction perpendicular to the direction of travel of the train; directional words such as "horizontal" and "vertical" are defined based on the accompanying drawings.

[0051] Please refer to Figures 1 to 10 The present application provides a high-speed train cleaning machine, including two car washing machines, both of which can be moved to the two end surfaces of the train along the travel direction of the train. The car washing machines include a gantry 1, a scrubbing device 2 and a high-pressure washing running device 3.

[0052] The gantry 1 can move along the traveling direction of the train.

[0053] The scrubbing device 2 is used for scrubbing the sides and ends of the train, and is disposed on the gantry 1 ; the scrubbing device 2 comprises a brush shaft 28 for scrubbing the ends and sides of the train and a brush shaft movement control device for controlling the spatial movement of the brush shaft 28 .

[0055] The high-pressure flushing mechanism includes a high-pressure flushing frame 314, a distance adjusting mechanism 316 for adjusting the distance between the high-pressure flushing frame 314 and the side of the train, a rotation control mechanism 32 for controlling the horizontal angle of the high-pressure flushing frame 314 and a high-pressure nozzle 318 for spraying detergent on the side and end face of the train; the distance adjusting mechanism and a plurality of high-pressure nozzles 318 are all arranged on the high-pressure flushing frame 314, and a crank-connecting rod mechanism is arranged on the high-pressure flushing frame 314, and it is connected to the high-pressure nozzle 318 to drive the high-pressure nozzle 318 to swing back and forth vertically.

[0056] It should be noted that the two car washers are used to clean the end and side faces of the train, and both can be moved along the travel direction of the train, that is, the longitudinal direction of the car wash station. One car washer can be moved to the first station of the front face of the train for cleaning. Figure 2 As shown, C is the first station and C1 is the front face of the train, and another car washing machine can be moved to the rear face of the train for cleaning, such as Figure 2 As shown, D is the second station and D2 is the rear end face of the train. Therefore, the car washing machine that can be moved to the first station for cleaning is called the first station car washing machine, and the car washing machine that can be moved to the second station for cleaning is called the second station car washing machine.

[0057] The first station car washing machine and the second station car washing machine both include a gantry 1, a scrubbing device 2 and a high-pressure washing running device 3, wherein the gantry 1 and the high-pressure washing running device 3 can both move in the longitudinal direction, the scrubbing device 2 is fixedly installed on the gantry 1, and the gantry 1, the scrubbing device 2 and the high-pressure washing running device 3 are all placed on both sides of the train.

[0058] The scrubbing device 2 includes a brush shaft 28 for scrubbing the end face and side face of the train and a brush shaft movement control device for controlling the spatial movement of the brush shaft 28; the high-pressure flushing running device 3 includes a high-pressure flushing mechanism and a crank-connecting rod mechanism; the high-pressure flushing mechanism includes a high-pressure flushing frame 314, a distance adjustment mechanism 316, a high-pressure nozzle 318 and a rotation control mechanism 32; a plurality of high-pressure nozzles 318 are arranged in the high-pressure flushing frame 314, and the high-pressure flushing frame 314 has openings at the positions where the high-pressure nozzles 318 are arranged, so that the high-pressure nozzles 318 spray detergent to the train; the rotation control mechanism 32 is fixed on the high-pressure flushing frame 314, and the rotation control mechanism 32 can control the horizontal rotation of the high-pressure flushing frame 314, thereby adjusting the horizontal angle of the high-pressure nozzles 318; the distance adjustment mechanism 316 can adjust the distance between the high-pressure flushing frame 314 and the side face of the train, and it is arranged on the high-pressure flushing frame 314; the crank-connecting rod mechanism is arranged on the high-pressure flushing frame 314, and it is connected to the high-pressure nozzles 318 to drive the high-pressure nozzles 318 to swing vertically.

[0059] During the use of the above device, when a train enters the car wash garage, it does not need to stop and wait, but only needs to move forward slowly, and the two car washers can move to the two end faces of the train respectively along the travel direction of the train. Therefore, the gantry 1 and the high-pressure washing running device 3 of the car wash machine at the first station move forward in the travel direction of the train, and at the same time, the brush shaft 28 in the brush washing device 2 installed on the gantry 1 brushes the side of the train until the car wash machine moves to the front end face of the train, and the brush shaft 28 is controlled by the brush shaft 28 moving device to move in space, and cooperates with the movement of the gantry 1, so that the bristles on the brush shaft 28 effectively fit the end face of the train for brushing.

[0060] After the scrubbing device 2 completes scrubbing, the high-pressure washing running device 3 moves to the front face of the train, the distance adjustment mechanism 316 adjusts the distance between the high-pressure washing frame 314 and the side of the train, so that the detergent sprayed by the high-pressure nozzle 318 in the high-pressure washing frame 314 covers the end face of the train, the rotation control mechanism 32 controls the rotation of the high-pressure washing frame 314 to adjust the horizontal angle of the high-pressure washing frame 314, and then adjusts the horizontal angle of the high-pressure nozzle 318, the crank connecting rod mechanism connects the high-pressure nozzle 318 to drive the high-pressure nozzle 318 to swing vertically, so that the high-pressure nozzle 318 can swing horizontally and vertically, and then the detergent sprayed by the high-pressure nozzle 318 can effectively cover the irregular curved surface of the end of the train, so as to realize the contour washing of the end face of the train. When the first station car washing machine moves to the front face of the train to complete the scrubbing and high-pressure washing operations, the scrubbing device 2 and the high-pressure washing running device 3 of the second station car washing machine can be moved to the rear end face and side of the train for cleaning, thereby saving the cleaning time of the high-speed train.

[0061] Therefore, the scrubbing device 2 and the high-pressure flushing running device 3 are both used to clean the sides and ends of the train. When cleaning the end face of the train, the high-pressure flushing mechanism of the high-pressure flushing running device 3 can control the rotation control mechanism 32 to drive the horizontal rotation of the high-pressure nozzle 318, control the vertical swing of the crank connecting rod mechanism to drive the vertical swing of the high-pressure nozzle 318, and control the distance adjustment mechanism 316 to adjust the distance between the high-pressure flushing frame 314 and the side of the train, thereby ensuring that the detergent sprayed by the high-pressure nozzle 318 can effectively cover the irregular curved surface of the end of the train; at the same time, the scrubbing device 2 can control the brush shaft 28 movement control device to adjust the spatial movement of the brush shaft 28, and cooperate with the walking action of the gantry 1 to make the bristles on the brush shaft 28 effectively fit the end face of the train for contour brushing. Therefore, a combination of brushing and high-pressure washing is used to clean the end and sides of the train, and the end of the train is brushed and washed in a contour manner, cleaning the entire area of ​​the end, avoiding the problem of the train end being difficult to clean due to its irregular curved surface, and solving the problem of the difficulty in cleaning pollutants on the side of the train, thereby enhancing the cleaning effect of the train. In addition, when the train is washed, there is no need to stop and wait. When one cleaning machine moves to the front end of the train to complete the brushing and high-pressure washing operations, the other cleaning machine moves to the rear end of the train to complete the brushing and high-pressure washing operations, thereby improving the cleaning efficiency of the train.

[0062] Optionally, the distance adjustment mechanism of the present application adopts an electric push rod structure to adjust the distance between the high-pressure washing frame 314 and the side of the train, and the number of electric push rods can be set according to actual needs; the rotation control mechanism 32 adopts a rotating motor to control the horizontal angle of the high-pressure washing frame 314.

[0063] In addition, optionally, the number of high-pressure nozzles 318 is not unique and can be set according to actual needs.

[0064] In this specific embodiment, the gantry 1 includes a ladder 11, a running channel 13, a gantry bracket 12 and a gantry running motor 14; the ladder 11 is arranged on the side of the gantry to avoid obstructing the train from passing through the garage, the running channel 13 is used for operators to stand on it for observation and maintenance, the gantry bracket 12 is arranged below the running channel 13 to facilitate the installation of the scrubbing device on the gantry bracket 12, and the gantry running motor 14 is used to drive the running wheels of the gantry 1 to move along the driving direction of the train, and the running wheels are arranged at the bottom end of the gantry 1.

[0065] It should be noted that the running wheel setting method of the present application is a conventional technical means, and its specific setting method can refer to the existing technology, and this application will not go into details.

[0066] In this specific embodiment, the gantry support 12 is provided with a train end face detection radar 26 for detecting the train end face and a gantry travel detection radar 27 for detecting the gantry travel state. Specifically, the train end face detection radar 26 is used to detect the longitudinal travel speed of the train, and the gantry travel detection radar 27 is used to detect the longitudinal travel speed of the gantry 1, so as to adjust the longitudinal travel speed of the gantry 1 according to the longitudinal travel speed of the train.

[0067] It should be noted that the train end face detection radar 26 and the gantry travel detection radar 27 are both connected to the control system through signals, so that the speed value is fed back to the control system. When the gantry 1 travel speed is lower than or higher than the upper limit value, the control system can transmit information instructions to the gantry travel motor 14 to increase or decrease the motor speed to adjust the travel speed of the gantry 1.

[0068] In this specific embodiment, a transverse travel motor 25 is provided at the upper end of the scrubbing device 2 , and the transverse travel motor 25 is slidably connected to the gantry bracket 12 .

[0069] Specifically, the transverse travel motor 25 can be slidably connected to the gantry bracket 12, and the transverse travel motor 25 is fixedly connected to the upper end of the scrubbing device 2, so that the transverse travel motor 25 controls the scrubbing device 2 to move in a direction perpendicular to the travel direction of the train. When the train end face detection radar 26 and the gantry travel detection radar 27 fail, and the gantry travel motor 14 fails, the scrubbing device 2 loses control, or the scrubbing device 2 cannot be moved away from the end face of the train, the transverse travel motor 25 can drive the scrubbing device 2 away from the train surface, and minimize the interference area of ​​the scrubbing device 2 on the train end face, thereby avoiding collision and damage between the train and the scrubbing device 2.

[0070] In this specific embodiment, the brush shaft movement control device includes a vertical telescopic mechanism, which includes a vertical telescopic arm 21 that can be vertically telescopic and a vertical telescopic electric push rod 22 for pushing the vertical telescopic arm 21 to be vertically telescopic. One end of the vertical telescopic arm 21 is connected to the horizontal walking motor 25, and the other end is connected to the vertical telescopic electric push rod 22.

[0071] Specifically, one end of the vertical telescopic arm 21 is fixedly connected to the transverse walking motor 25, and the other end of the vertical telescopic arm 21 is fixedly connected to the vertical telescopic electric push rod 22, and the vertical telescopic electric push rod 22 and the vertical telescopic arm 21 are both vertically arranged, so that the vertical telescopic electric push rod 22 pushes the vertical telescopic arm 21 to extend and retract in the vertical height of the train, which is convenient for adjusting the distance between the brush shaft 28 and the end face of the train.

[0072] Optionally, the vertical telescopic arm 21 in the present application is in the form of a three-section arm with a rope-row slider, and the vertical stroke can reach 2.8m, covering the cleaning area at the vertical height of the train. Other types of structures can also be selected according to actual needs.

[0073] In this specific embodiment, the brush shaft movement control device also includes a horizontal rotation mechanism 23 for controlling the horizontal position of the brush shaft 28, a rotation mechanism 24 for controlling the rotation of the brush shaft 28, and a swing mechanism 29 for controlling the vertical and horizontal state conversion of the brush shaft 28; the horizontal rotation mechanism 23 is connected to the lower part of the vertical telescopic mechanism, the turntable of the horizontal rotation mechanism 23 is connected to the upper end of the swing mechanism 29, the side end of the swing mechanism 29 is connected to the rotation mechanism 24, and the output ends of the rotation mechanism 24 and the swing mechanism 29 are both connected to the brush shaft 28.

[0074] Specifically, the horizontal rotating mechanism 23 is arranged at the lower part of the vertical telescopic mechanism, the horizontal rotating mechanism 23 is fixedly connected to the vertical telescopic mechanism, and the central axis of its turntable is parallel to the vertical telescopic direction of the vertical telescopic mechanism, so that the horizontal rotating mechanism 23 drives the brush shaft 28 to rotate around its central axis, thereby adjusting the horizontal position of the brush shaft 28; the upper end of the swing mechanism 29 is provided with a horizontal rotating mechanism 23, and the side end of the swing mechanism 29 is provided with a rotating mechanism 24, the swing mechanism 29 is fixedly connected to the horizontal rotating mechanism 23 and the rotating mechanism 24 through a fixing plate, the output end of the rotating mechanism 24 is connected to the brush shaft 28 to drive the brush shaft 28 to rotate around its central axis, and the output end of the swing mechanism 29 is connected to the brush shaft 28 to realize the vertical state and horizontal state conversion of the rotating shaft 28.

[0075] During use of the above structure, the swing mechanism 29 in the brushing device swings the brush shaft 28 upward to a horizontal state, and then the horizontal rotating mechanism 23 moves the brush shaft 28 to the end face of the train, and makes the brush shaft 28 perpendicular to the travel direction of the train to complete the conversion of the brush shaft 28 from the side brush state to the end brush state, and then the vertical telescopic mechanism controls the vertical telescopic extension of the brush shaft 28 to adjust the height of the brush shaft 28 on the end face of the train, and cooperates with the walking action of the gantry 1 along the travel direction of the train to complete the brushing of the brush shaft 28 from top to bottom on the end face of the train, so that the bristles on the brush shaft 28 effectively fit the end face of the train for brushing, thereby completing the brushing profiling function.

[0076] Optionally, the horizontal slewing mechanism 23, the rotating mechanism 24 and the swinging mechanism 29 of the present application respectively adopt a slewing reduction motor, a rotating motor and a swinging motor with simple structure and convenient installation.

[0077] It should be noted that the length of the brush shaft 28 of the present application is adapted to the width of the end face of the train. Since the height of the train is greater than the width of the train, when the side brush of the car washing machine at the first station is used, that is, the side of the train is brushed, the vertical telescopic mechanism of the brushing device 2 controls the vertical extension of the brush shaft 28 for rotational brushing, while the side brush of the car washing machine at the second station keeps the vertical telescopic mechanism from extending, thereby ensuring that the side of the train is cleaned without dead angles.

[0078] In this specific embodiment, the crank-connecting rod mechanism includes a reciprocating mechanism motor 311 arranged at the upper end of the high-pressure washing frame 314, a crank connecting rod 312, a long connecting rod 313 and a short connecting rod 315 arranged along the height of the high-pressure washing frame 314; one end of the crank connecting rod 312 is connected to the output shaft of the reciprocating mechanism motor 311, and the other end of the crank connecting rod 312 is hinged to the long connecting rod 313, one end of a plurality of short connecting rods 315 is hinged to the long connecting rod 313, and the other end thereof is hinged to the corresponding rotating shaft 319; the interface of the rotating shaft 319 is connected to the high-pressure nozzle 318, and a plurality of rotating shafts 319 are horizontally arranged in the high-pressure washing frame 314.

[0079] Specifically, the crank-connecting rod mechanism is used to drive the high-pressure nozzle 318 to swing back and forth vertically.

[0082] It should be noted that the signal of the ground rail running wheel motor 38 is connected to the control system so as to remotely control the rotation frequency of the ground rail running wheel motor, thereby adjusting the longitudinal moving speed of the high-pressure flushing running device 3.

[0084] Specifically, in order to further enhance the flushing effect of the train, on the basis of the high-pressure flushing running device 3 having a high-pressure flushing structure for flushing the train, a detergent spraying mechanism is added, the detergent spraying mechanism is arranged on one side of the support frame 31, and the high-pressure flushing mechanism is arranged on the other side of the support frame 31; the detergent spraying mechanism includes a detergent spraying pipe 36 and an outer cylinder 39, the outer cylinder 39 is arranged on the outside of the detergent spraying pipe 36, the outer cylinder 39 contains detergent for cleaning the train, and the detergent spraying pipe 36 extracts the detergent in the outer cylinder 39 to flush the side and end faces of the train.

It should be noted that the water pressure value of the high-pressure water pump 33 needs to be adjusted before cleaning the train, and the water pressure value is adjusted according to the mileage of the train and the pollution state obtained by visual observation to ensure the removal effect of pollutants.

[0086] Optionally, the high-pressure water pump 33 of the present application adopts a plunger pump. The type and setting position of the high-pressure water pump 33 are not unique and can be adjusted according to actual needs.

[0087] The use process of the above-mentioned high-speed train cleaning machine structure is as follows:

[0088] When the train first enters the garage, the first station car washing machine and the second station car washing machine are both located at the entrance of the garage, and the brush shafts 28 of the two stations are in the side brushing state. When the high-speed train slowly enters the garage, the gantry running wheel motor 14 and the ground rail running wheel motor 38 of the first station car washing machine are started, and the high-pressure washing running device 3 and the gantry 1 move forward longitudinally. The longitudinal forward start time of the gantry 1 is earlier than that of the high-pressure washing running device 3 to ensure that the train is brushed after being sprayed with detergent. At the same time, the detergent spray pipes 36 of the high-pressure washing running device 3 of the first station car washing machine and the second station car washing machine wash the side of the high-speed train, and the brush shaft 28 of the brush washing device 2 rotates to brush.

[0089] When the first station car washing machine moves forward to the front end face of the train, the first station car washing machine moves forward to the front of the front end face of the high-speed train, the detergent spray pipe 36 sprays detergent to the front end face of the train, and the distance to the end face of the train is detected by the train end face detection radar 26. If it is greater than or equal to the set safety distance, the brush shaft 28 is swung up 90 degrees by the swing mechanism 29, and then the horizontal rotation mechanism 23 is horizontally rotated 90 degrees to move the brush shaft 28 to the front end face of the train and perpendicular to the travel direction of the train, and the rotating mechanism 24 is controlled to make the brush shaft 28 rotate. At the same time, the driving speed of the gantry running motor 14 is slowly reduced, cooperating with the train end face detection radar 26, until the bristles of the brush shaft 28 touch the top of the front end face of the train and reach a bristle eating amount of 100mm.

[0090] When the first station car washer is profiling and brushing the end face of the train, the gantry running wheel motor 14 slowly speeds up, and the vertical telescopic electric push rod 22 pushes the vertical telescopic arm 21, so that the bristles of the brush shaft 28 are brushed from top to bottom. After brushing, the rotary reduction motor controls the brush shaft 28 to rotate 90 degrees in the opposite direction, and the vertical telescopic electric push rod 22 retracts the vertical telescopic arm 21, and drives the swing mechanism 29 to swing the brush shaft 28 down 90 degrees to restore it to the side brushing state. At the same time, the brushing device 2 is moved to the back of the high-pressure washing running device 3 through the gantry running motor 14.

[0091] When the first station car washer is profiling and high-pressure washing the end face of the train, the ground rail running wheel motor 38 is controlled to move the high-pressure washing running device 3 longitudinally to the front face of the train, and the distance adjustment mechanism 316 pushes out the high-pressure washing support frame 314, and the high-pressure water pump 33, the reciprocating mechanism motor 311 and the rotation control mechanism 32 work, so that the high-pressure nozzle 318 can swing horizontally and vertically for washing. After completing the high-pressure washing of the front face of the train, the distance adjustment mechanism 316 is controlled to retract the high-pressure washing support frame 314.

[0092] When the first station car washing machine high-pressure washes the side of the train, the brush shaft 28 rotates around its central axis, and the vertical telescopic arm electric push rod 22 extends, and its extended length is the train cleaning height minus the train width. At the same time, the high-pressure washing running device 3 is in a high-pressure washing state, and the distance adjustment mechanism 316 adjusts the distance between the high-pressure nozzle 318 and the side of the train to meet the set distance. At the same time, the rotating mechanism 32 rotates the high-pressure washing frame 314 to make the outlet direction of the high-pressure nozzle 318 close to and perpendicular to the side of the train, and the reciprocating mechanism motor 311 is started to perform reciprocating swinging of the high-pressure nozzle 318 for washing.

[0093] During the above operation of the car washer at the first station, the brush shaft 28 of the brush shaft device 2 of the car washer at the second station keeps brushing the side of the train, and the detergent spray pipe 36 of the high-pressure washing running device 3 washes the side of the train. At this time, the car washer at the first station washes the side of the train, and the car washer at the second station brushes and washes the side of the train.

[0094] When the second station car washer moves forward to the rear end face of the train, when the train end face detection radar 26 detects the distance of the train end face, which is greater than or equal to the set safety distance, the brush shaft 28 is swung up 90 degrees by the swing mechanism 29, and then the horizontal rotary mechanism 23 is horizontally rotated 90 degrees, and the gantry travel motor 14 is driven, and the bristles of the brush shaft 28 are close to the rear end face of the train until the bristles touch the top of the front end face of the train. This action process is similar to the first station car washer. The subsequent second station car washer's profiling brushing of the train's end face, profiling of the train's end face and high-pressure washing of the train's side are similar to the above-mentioned first station car washer, and the operation process will not be described in detail.

[0095] It should be noted that a proximity switch is set at the end point of the outbound direction of the garage. When the proximity switch 15 detects the end point, the car washing machine at the first station can be stopped slowly, eliminating the risk of the car washing machine falling off the track.

[0096] Optionally, the number of car wash stations in the present application is not unique, and parallel horizontal stations can be set according to the number of trains, such as Figure 1 The B area.
