Description

Technical Field

[0001] The invention relates to the technical field of railway maintenance, and in particular to a rail cleaning device. Background Art

[0002] Railways are track lines for trucks and other vehicles to travel on two parallel tracks pulled by locomotives. As the speed of high-speed trains and EMUs increases, the risks faced by trains and passengers are increasing. These risks mainly come from drivers, dispatchers, railway track environment and external operating environment. In addition, the garbage on the railway comes from outside the protective net. Affected by natural factors such as wind and rain, the garbage can easily enter the railway tracks inside the protective net. Therefore, cleaning agencies are needed to clean up the garbage on the railway to reduce the risk of accidents.

[0003] When garbage falls on the railway track, the cleaning method usually adopted in the existing technology is to have workers sit on the transport vehicle, and when they find garbage along the railway, they get off the transport vehicle and clean up the garbage manually. This method of cleaning railway garbage takes too long and the effect of cleaning garbage is not obvious, resulting in the failure to remove the garbage from the railway in time, which in turn causes the garbage to be rolled into the wheels of the railway car when the train passes, causing movement resistance to the train, increasing energy consumption, and even causing the risk of locking the train wheel system, turning the rolling friction between the wheel and the track into sliding friction, damaging the wheel and the track.

DETAILED DESCRIPTION

[0051] The present invention will be further described below in conjunction with the accompanying drawings.

[0052] Please also read Figure 1 , Figure 2 and Figure 3 The present invention provides a rail cleaning device 100, comprising a housing 1, a fixing frame 2, a grabbing assembly 15 and a driving assembly 6. The housing 1 can move in a first direction (such as Figure 1 The fixing frame 2 is connected to one end of the box body 1, and the fixing frame 2 is provided with a second direction (as shown in the X direction). Figure 3 The gripping assembly 15 includes a first rod body 13, a connecting seat 12 and a mechanical gripper 19. The first rod body 13 extends in a third direction (as shown in the Y direction). Figure 1 The first rod 13 is connected to the connecting seat 12, and the mechanical gripper 19 is connected to the connecting seat 12, wherein the first direction, the second direction and the third direction are perpendicular to each other. The driving assembly 6 is arranged on the box body 1, and the driving assembly 6 is connected to the connecting seat 12 and can drive the first rod 13 to move along the guide rod 14 through the connecting seat 12, so as to drive the mechanical gripper 19 to move.

[0053] Among them, track wheels 35 are arranged at the bottom of the box body 1. When the rail cleaning device 100 is placed on the rail, the track wheels 35 cooperate with the rail and can roll along the rail, thereby driving the rail cleaning device 100 to move along the rail.

[0054] In this embodiment, the rail cleaning device 100 is placed on the rail, the first direction is roughly coincident with the extension direction of the rail, the second direction can be roughly located in the horizontal plane and roughly perpendicular to the extension direction of the rail, and the third direction is roughly parallel to the vertical direction. When the box body 1 moves along the rail to a position where there is garbage, the drive assembly 6 applies a force along the second direction to the connecting seat 12 to drive the first rod body 13 to move along the guide rod 14, thereby driving the mechanical gripper 19 to move in a horizontal plane in a direction perpendicular to the rail, so that the mechanical gripper 19 can grab the garbage and place it in the collection box 20 of the box body 1.

[0055] The driving assembly 6 of the present application drives the first rod body 13 to move along the guide rod 14 through the connecting seat 12 to drive the mechanical gripper 19 to move, thereby expanding the gripping range of the mechanical gripper 19, that is, expanding the cleaning range of the rail cleaning device 100, and improving the cleaning efficiency and cleaning effect.

[0056] Please also read Figure 1 , Figure 2 and Figure 4 In some embodiments, the rail cleaning device 100 further includes a connecting plate 8, which is connected to the fixed frame 2. The driving assembly 6 includes a second rod body 10, a limiting sleeve 9, and a spring 11. The second rod body 10 is rotatably connected to the connecting seat 12, and the rotation axis of the second rod body 10 extends along the first direction. The limiting sleeve 9 is sleeved on the second rod body 10, and the limiting sleeve 9 is rotatably connected to the connecting plate 8, and the rotation axis of the limiting sleeve 9 extends along the first direction. The spring 11 is compression sleeved on the second rod body 10, and the two ends of the spring 11 are respectively abutted against the connecting seat 12 and the limiting sleeve 9. Among them, when the limiting sleeve 9 rotates, it drives the second rod body 10 to rotate, so that the elastic force applied by the spring 11 to the connecting seat 12 forms a component force along the second direction.

[0057] It should be noted that the rotation angle range of the limiting sliding sleeve 9 in this embodiment is limited, that is, the limiting sliding sleeve 9 in this embodiment cannot rotate 360°, but swings within a certain angle range.

[0058] Specifically, when the rail cleaning device 100 is not working, the limiting sleeve 9 can be in the initial position. At this time, the extension direction of the second rod body 10 can be parallel to the vertical direction, and the direction of the elastic force applied by the spring 11 to the connecting seat 12 can be parallel to the vertical direction, that is, the spring 11 does not form a component force along the second direction on the connecting seat 12, and the connecting seat 12 will not form a component force along the second direction on the first rod body 13, so the first rod body 13 will not move along the guide rod 14.

[0059] When the rail cleaning device 100 is working, the limiting sleeve 9 rotates to drive the second rod body 10 to rotate. At this time, the direction of the elastic force applied by the spring 11 to the connecting seat 12 is inclined relative to the second direction and the third direction. Therefore, the elastic force applied by the spring 11 to the connecting seat 12 forms a component force along the second direction, causing the connecting seat 12 to apply a component force along the second direction to the first rod body 13, so that the first rod body 13 moves along the guide rod 14, thereby driving the mechanical gripper 19 to move along the second direction.

[0060] It should be noted that the limiting sleeve 9 has an extreme position when it rotates, and when the limiting sleeve 9 is at the extreme position, the extension direction of the second rod 10 forms an angle with both the second direction and the third direction. It is understandable that when the limiting sleeve 9 rotates from the initial position to the extreme position, the second rod 10 also rotates to the extreme position relative to the connecting seat 12, so that the first rod 13 moves to the extreme position on the guide rod 14, causing the mechanical gripper 19 to move to the farthest position in the second direction, that is, the extreme position of the limiting sleeve 9 determines the movement range of the mechanical gripper 19 in the second direction.

[0061] In this embodiment, the limiting sleeve 9 swings to drive the second rod body 10 to rotate relative to the connecting seat 12, thereby driving the first rod body 13 to drive the mechanical gripper 19 to move, thereby enhancing the stability and controllability of the drive of the first rod body 13, and at the same time enabling precise movement of the mechanical gripper 19.

[0062] In some other embodiments, the driving assembly 6 can be connected to the second rod body 10 and drive the second rod body 10 to rotate.

[0063] Please also read Figure 2 , Figure 4 and Figure 5 In some more specific embodiments, the driving assembly 6 further includes a limit plate 63 and a first bending rod 65. The limit plate 63 is rotatably connected to the box body 1, the rotation axis of the limit plate 63 extends along the first direction, and the limit plate 63 can swing around the rotation axis, the limit plate 63 is provided with a first movable cavity 631, one end of the first bending rod 65 is slidably connected to the first movable cavity 631, and the other end is passed through the connecting plate 8 and connected to the limit sleeve 9, and the rotation axis of the first bending rod 65 coincides with the rotation axis of the limit sleeve 9. Among them, when the limit plate 63 swings, it drives the first bending rod 65 to rotate to drive the limit sleeve 9 to rotate.

[0064] In order to achieve the swinging of the above-mentioned limiting sleeve 9 within a certain angle range, the present embodiment is connected to the box body 1 with a limiting plate 63 that swings within a certain angle range. When the limiting plate 63 swings, it drives the first bending rod 65 to rotate, and at this time, one end of the first bending rod 65 connected to the first movable cavity 631 can move in the first movable cavity 631 to prevent the first bending rod 65 from being stuck with the limiting plate 63. Since the limiting plate 63 swings within a certain angle range, the first bending rod 65 will not rotate within a 360° range, that is, the first bending rod 65 swings within a certain angle range along its own rotation axis, thereby driving the limiting sleeve 9 to swing within a certain angle range.

[0065] In this embodiment, the limiting plate 63 swings within a certain angle range and the first bending rod 65 limits the limiting sleeve 9 from swinging within a certain angle range. At the same time, a first movable cavity 631 is provided to prevent the first bending rod 65 and the limiting plate 63 from getting stuck.

[0066] In some examples, a first limit block 64 may be mounted on one end of the first bending rod 65 connected to the first active cavity 631, and the side wall of the first limit block 64 abuts against the inner wall of the first active cavity 631 formed by the limit plate 63, thereby preventing the first bending rod 65 from having an empty stroke in the first active cavity 631.

[0067] Please continue reading Figure 2 , Figure 4 and Figure 5 In some more specific embodiments, the limiting plate 63 is provided with a second active cavity 632. The driving assembly 6 further includes a supporting plate 7, a motor 3 and a second bending rod 61. The supporting plate 7 is connected to the box body 1, the motor 3 is provided in the box body 1, one end of the second bending rod 61 is slidably connected to the second active cavity 632, and the other end penetrates the supporting plate 7 and is connected to the motor 3. The motor 3 drives the second bending rod 61 to rotate to drive the limiting plate 63 to swing.

[0068] The transmission path in this embodiment is that the motor 3 can drive the second bending rod 61 to rotate 360°. When the second bending rod 61 rotates 360°, it can drive the limiting plate 63 to swing within a certain angle range. When the limiting plate 63 swings within a certain angle range, it drives the first bending rod 65 to swing within a certain angle range. When the first bending rod 65 swings within a certain angle range, it drives the limiting sleeve 9 to swing within a certain angle range.

[0069] It should be noted that the distance between one end of the second bending rod 61 connected to the limit plate 63 and the rotation axis of the limit plate 63 is smaller than the distance between one end of the first bending rod 65 connected to the limit plate 63 and the rotation axis of the limit plate 63, so as to meet the requirements of the above-mentioned transmission path.

[0070] In some embodiments, a second limit block 62 can be mounted on one end of the second bending rod 61 connected to the second active cavity 632. The side wall of the second limit block 62 abuts against the inner wall of the second active cavity 632 formed by the limit plate 63, thereby preventing the second bending rod 61 from having an empty stroke in the second active cavity 632.

[0071] In some other examples, the drive assembly 6 may also include a connecting shaft 4 and a flywheel 5, the two ends of the connecting shaft 4 are respectively connected to the motor 3 and the end of the second bending rod 61 away from the second active cavity 632, and the flywheel 5 is sleeved on the connecting shaft 4. Among them, the flywheel 5 is a physical energy storage device that can store energy when the motor 3 is driven. When the motor 3 stops driving or requires additional power, the flywheel 5 can release the stored energy to provide a continuous or enhanced power output for the drive assembly 6, which is particularly important for the rail cleaning device 100 when it requires instantaneous high power or continuous and stable operation. At the same time, through the cycle of energy storage and energy release of the flywheel 5, the energy utilization efficiency of the motor 3 can be optimized and unnecessary energy consumption can be reduced. This is helpful to reduce energy consumption and operating costs for the rail cleaning device 100 that needs to work continuously for a long time. In addition, the flywheel 5 has a large moment of inertia, which can effectively reduce the fluctuation and mutation of power output. When the rail cleaning device 100 is working, the stable power output helps to maintain the stability of the mechanical gripper 19 and the uniformity of the cleaning effect.

[0072] In some other more specific embodiments, the motor 3 may also be directly connected to the limiting plate 63 .

[0073] Please also read Figure 1 , Figure 2 and Figure 6 In some embodiments, the gripping assembly 15 further includes a first telescopic rod 16 and a second telescopic rod 18. One end of the first telescopic rod 16 is connected to the connection seat 12, and the other end can be telescoped along the second direction. One end of the second telescopic rod 18 is connected to an end of the first telescopic rod 16 away from the connection seat 12, and the other end can be telescoped along the third direction and connected to the mechanical gripper 19.

[0074] When the garbage is located below the mechanical gripper 19, the second telescopic rod 18 extends and drives the mechanical gripper 19 to descend to grab the garbage. After the mechanical gripper 19 grabs the garbage, the second telescopic rod 18 shortens and drives the mechanical gripper 19 to rise, and the connecting seat 12 drives the first rod body 13 to move along the guide rod 14, so that the mechanical gripper 19 can place the garbage in the collection box 20.

[0075] When the garbage is on the outside of the mechanical gripper 19 in the second direction, the first telescopic rod 16 extends along the second direction, thereby driving the mechanical gripper 19 to move outward along the second direction. When the mechanical gripper 19 moves to directly above the garbage, the second telescopic rod 18 extends and drives the mechanical gripper 19 to descend to grab the garbage. After the mechanical gripper 19 grabs the garbage, the second telescopic rod 18 shortens and drives the mechanical gripper 19 to rise, the first telescopic rod 16 contracts and drives the mechanical gripper 19 to retract, and the connecting seat 12 drives the first rod body 13 to move along the guide rod 14, so that the mechanical gripper 19 can place the garbage in the collection box 20.

[0076] In this embodiment, the first telescopic rod 16 is provided to expand the gripping range of the mechanical gripper 19, thereby improving the cleaning efficiency.

[0077] In some other embodiments, the telescopic direction of the first telescopic rod 16 may also be inclined relative to the second direction.

[0078] See also Figure 6 In some more specific embodiments, the number of the first telescopic rod 16, the second telescopic rod 18 and the mechanical gripper 19 are all two, the two first telescopic rods 16, the two second telescopic rods 18 and the two mechanical grippers 19 are arranged in a one-to-one correspondence, and the two first telescopic rods 16 are respectively arranged on both sides of the connecting seat 12 in the second direction.

[0079] In this embodiment, a first telescopic rod 16 is provided on both sides of the connecting seat 12, which can simultaneously drive two mechanical grippers 19 away from the connecting seat 12 in the second direction, so that the two mechanical grippers 19 can grab the garbage on both sides at the same time, thereby further improving the cleaning efficiency.

[0080] In some other more specific embodiments, the number of the second telescopic rods 18 and the mechanical grippers 19 can be three or even more.

[0081] Please also read Figure 2 and Figure 7 In some embodiments, the housing 1 is provided with a receiving cavity 38, and a through hole 39 communicating with the receiving cavity 38 is provided at the bottom of the housing 1. The rail cleaning device 100 further includes a cleaning brush 29 and a grinding disc 30, both of which are disposed in the receiving cavity 38 and can extend out of the receiving cavity 38 through the through hole 39.

[0082] The cleaning brush 29 may be connected to the first motor box 28 and rotated by the drive of the first motor box 28. Similarly, the grinding disc 30 may be connected to the second motor box 37 and rotated by the drive of the second motor box 37.

[0083] When the rail cleaning device 100 only performs the cleaning method of clamping garbage, the cleaning brush 29 and the grinding disc 30 are accommodated in the accommodating chamber 38. When the rail cleaning device 100 performs the cleaning method of cleaning the rail, the cleaning brush 29 and the grinding disc 30 extend through the hole 39, thereby cleaning and grinding the surface of the rail. It can be understood that the cleaning method of clamping garbage and the cleaning method of cleaning the rail can be performed simultaneously or separately, which is not limited here.

[0084] In some other embodiments, a grinding disc 30 or a cleaning brush 29 may be provided.

[0085] Please continue reading Figure 2 and Figure 7 In some more specific embodiments, the rail cleaning device 100 further includes two guide posts 27 and a movable plate 26. The two guide posts 27 are disposed in the accommodating cavity 38, and the extending directions of the two guide posts 27 are parallel to the axial direction of the through hole 39. The cleaning brush 29 and the grinding disc 30 are connected to the movable plate 26, and the movable plate 26 is sleeved on the two guide posts 27 and can move along the guide posts 27.

[0086] The number of the through holes 39 may be two, and the cleaning brush 29 and the grinding disc 30 correspond to one of the through holes 39 respectively.

[0087] In this embodiment, when the rail cleaning device 100 executes the cleaning method of cleaning the rail, the movable plate 26 moves along the guide column 27 and drives the cleaning brush 29 and the grinding disc 30 to move, so that the cleaning brush 29 and the grinding disc 30 extend through the through hole 39 at the same time and clean and grind the rail respectively.

[0088] The two guide posts 27 can limit the movable plate 26 to move only along the extension direction of the guide posts 27 . Meanwhile, the two guide posts 27 can also prevent the movable plate 26 from tilting up on one side and sinking on the other side during movement.

[0089] In some other more specific embodiments, the number of the guide post 27 may also be one.

[0090] Please continue reading Figure 2 and Figure 7 In some more specific embodiments, the rail cleaning device 100 further includes a slide rail 25, a third telescopic rod 23 and a cross-shear frame 24. The slide rail 25 is disposed on the movable plate 26, the third telescopic rod 23 is disposed in the accommodating cavity 38, and the telescopic direction of the third telescopic rod 23 is parallel to the extension direction of the slide rail 25. The cross-shear frame 24 has at least two movable ends 22, one of which is slidably disposed on the slide rail 25, and the other movable end 22 is connected to the third telescopic rod 23. When the third telescopic rod 23 is extended or retracted, the cross-shear frame 24 is driven to extend or retract to drive the movable plate 26 to move.

[0091] The number of the slide rails 25 and the third telescopic rods 23 can both be two, and the extension direction of the slide rails 25 and the telescopic direction of the third telescopic rods 23 can both be parallel to the first direction. The cross-cutting frame 24 can have four movable ends 22, two of which are respectively connected to the two third telescopic rods 23, and the other two movable ends 22 are respectively slidably disposed on the two slide rails 25.

[0092] When the rail cleaning device 100 executes the cleaning method of cleaning the rails, the two third telescopic rods 23 are extended, so that the two movable ends 22 connected to the two third telescopic rods 23 are close to each other in the first direction, and at the same time, the two movable ends 22 connected to the slide rail 25 are driven to approach each other in the first direction, so that the height of the shear frame 24 in the third direction is increased, thereby driving the movable plate 26 to move along the third direction and avoiding displacement in the first direction and the second direction, thereby driving the cleaning brush 29 and the grinding disc 30 to extend through the through hole 39 and respectively clean and grind the rails.

[0093] Please refer again Figure 1 In some embodiments, the rail cleaning device 100 further includes a support rod 32, which is disposed on the outer wall of the box body 1 and can be extended and retracted along a third direction.

[0094] When problems occur during the cleaning process of the rail cleaning device 100, the support rod 32 can be extended and supported on the ground, thereby propping up the rail cleaning device 100 and making the rail cleaning device 100 suspended in the air, preventing the rail cleaning device 100 from moving when the rail cleaning device 100 is being repaired.

[0095] In some examples, the rail cleaning device 100 further includes an extension seat 31, a rotating seat 33 and a support leg 34. The extension seat 31 is disposed on the outer wall of the box body 1. Both ends of the support rod 32 are respectively connected to the extension seat 31 and the rotating seat 33. The side of the rotating seat 33 facing away from the rotating seat 33 is connected to the support leg 34. When a problem occurs during the cleaning process of the rail cleaning device 100, the extension seat 31 drives the support rod 32 to extend and drives the rotating seat 33 and the support leg 34 close to the ground, and finally the support leg 34 is supported on the ground.
