Description

Technical Field

[0001] The present application relates to a side suction device and a railway tunnel cleaning vehicle, belonging to the technical field of railway machinery design and manufacturing. Background Art

[0002] The railway tunnel cleaning vehicle is used for tunnel dust removal and coal removal. The vehicle can clean the track bed of high-speed railways, ordinary railways and stations, absorb dust, solid debris and tiny stones deposited or adsorbed on the surface of the track bed, ensure the cleanliness of the railway and driving safety, prevent dust and debris from polluting the air and damaging the sensor components of high-speed trains, especially EMUs, and ensure safe operation of the line.

[0003] The side suction device is the main working device of the railway tunnel cleaning vehicle. The convenience and flexibility of the working device position adjustment mechanism directly determines the operating performance of the railway tunnel cleaning vehicle. At present, the mechanisms used in China to achieve the position adjustment of the working device are mostly mechanical arms with vertical lifting and horizontal lateral guide rail slide mechanisms and mechanical arms with multi-section arm mechanisms with rotation functions.

Although the control of the robotic arm of the vertical lifting and horizontal lateral movement guide rail slide mechanism is simple, when the working device has a large operating range, it is not conducive to the layout of the conveying pipeline due to limited space, resulting in pipeline obstruction, increased local resistance, and blockage.

[0056] 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.

[0057] In the process of implementing this application, the inventors found that the mechanisms commonly used to achieve position adjustment of the working device are mostly robotic arms with vertical lifting and horizontal transverse guide rail slide mechanisms and robotic arms with multi-section arm mechanisms with rotation functions. This structure requires a large installation space, which is not conducive to the layout of the working device.

[0058] In view of the above problems, a side suction device is provided in the embodiment of the present application, which is suitable for application to a railway tunnel cleaning vehicle, such as Figure 1-Figure 3 As shown, the side suction device includes a support mechanism 1 provided on a railway tunnel cleaning vehicle, a moving mechanism 2 connected to the support mechanism 1, a suction mechanism 3 provided at the end of the moving mechanism 2 for sucking dirt on the operating surface, and a sewage suction pipeline 4 having one end connected to the suction mechanism 3 and the other end connected to the railway tunnel cleaning vehicle;

[0059] Among them, the moving mechanism 2 has a first working state and a second working state. In the first working state, the moving mechanism 2 is moved relative to the supporting mechanism 1 by the force, thereby driving the suction mechanism 3 away from the supporting mechanism 1 and close to the operating surface. The suction mechanism 3 generates negative pressure to clean and suck the dirt on the operating surface. After the dirt enters the suction mechanism 3, it is transported to the railway tunnel cleaning vehicle through the sewage suction pipeline 4; in the second working state, the moving mechanism 2 is moved relative to the supporting mechanism 1 by the force, thereby driving the suction mechanism 3 away from the operating surface and close to the support mechanism 1.

[0060] Specifically, the motion mechanism 2 in the present application can realize the pitch, oblique extension, vertical lifting and lowering, and the swing and leveling functions of the suction device, and can also realize one-key expansion and retraction, realizing the coal cleaning operation from the outside of the sleeper to the ballast wall, the top surface of the drainage ditch cover, and the outside of the sleeper to the double-track center line area; the dirt enters the suction mechanism 3 and is transported to the dust removal system of the railway tunnel cleaning vehicle through the sewage suction pipeline 4. After the dust is settled and filtered by the dust removal system, it is discharged to the conveyor belt through the unloading system. The conveyor belt transports the coal powder to the material car, realizing a full set of coal powder cleaning operations on both sides of the line sleepers.

[0061] Further, the motion mechanism 2 includes a first motion mechanism 21 and a second motion mechanism 22. The first motion mechanism 21 is connected to the support mechanism 1, and the first motion mechanism 21 is moved relative to the support mechanism 1 by the force; the second motion mechanism 22 is connected to the first motion mechanism 21, and the second motion mechanism 22 is moved relative to the first motion mechanism 21 by the force. It should be noted that the second motion mechanism 22 can also move relative to the support mechanism 1. There is no restriction on the sequence and movement mode of the first motion mechanism 21 and the second motion mechanism 22 relative to the support mechanism 1. The sequence includes but is not limited to the first motion mechanism 21 first moving relative to the support mechanism 1, and the second motion mechanism 22 then moving relative to the support mechanism 1 or the second motion mechanism 22 moving relative to the first motion mechanism 21, or the second motion mechanism 22 first moving relative to the support mechanism 1 or moving relative to the first motion mechanism 21, and the first motion mechanism 21 then moving relative to the support mechanism 1; the movement mode includes but is not limited to translation, swinging, telescopic, lifting, etc.

[0062] Furthermore, the first motion mechanism 21 includes a first connecting member 211 rotatably connected to the support mechanism 1, a first swinging member 212 rotatably connected to the support mechanism 1 at one end and connected to the first connecting member 211 at the other end, and a first telescopic assembly 213 arranged on the first connecting member 211; the first swinging member 212 generates a force to swing around the support mechanism 1, and drives the first connecting member 211 to swing relative to the support mechanism 1, and the first telescopic assembly 213 is subjected to the force to reciprocate along the extension direction of the first connecting member 211. Among them, the first swinging member 212 can be a variable amplitude oil cylinder or a cylinder 51 capable of swinging, etc., which is not limited here; the first connecting member 211 is a connecting rod, which plays a role in fixing and driving the first telescopic assembly 213 to swing as a whole; the reciprocating movement includes but is not limited to telescopic, sliding and other ways that can achieve reciprocation. As can be seen from the above, the first telescopic assembly 213 can simultaneously achieve telescopic and relative movement of the support mechanism 1.

[0063] Optionally, the first telescopic assembly 213 includes a first arm, a second arm and a first telescopic member 2132, wherein the first telescopic member 2132 is disposed in the second arm, the first arm is sleeved with the first connecting member 211, and the second arm is sleeved with the first arm. The first telescopic member 2132 may be a telescopic oil cylinder, a cylinder 51 or the like that can realize a telescopic mode, and the first telescopic member 2132 generates a force to drive the second arm to move along the first arm, thereby driving the first arm to move along the first connecting member 211, so as to realize that the second arm is close to or away from the first arm, and the first arm is close to or away from the first connecting member 211.

[0064] Optionally, the first connecting member 211 is sleeved on the outside of the first arm, and the first arm is sleeved on the outside or inside of the second arm; the first arm has a first position completely located in the first connecting member 211, and a second position extending out of the first connecting member 211, and the first arm can move between the first position and the second position; the second arm has a third position completely located in the inside or outside of the first arm, and a fourth position extending out of the first arm, and the second arm can move between the third position and the fourth position. The first telescopic member 2132 generates a force to drive the second arm to move back and forth between the third position and the fourth position, and can also stay at any position between the third position and the fourth position; in the initial state, the first arm is located at the first position, and the second arm is located at the third position. When the second arm is located at the fourth position, the first telescopic member 2132 continues to drive the second arm to move in a direction away from the first arm. At this time, the first arm moves from the first position to the second position, and can also stay at any position between the first position and the second position. Both can be adjusted as needed, and there is no limitation here.

[0065] Specifically, the first connecting member 211 is sleeved on the outside of the first arm, and one of the inside of the first connecting member 211 or the outside of the first arm can be provided with a slide rail, and the other can be provided with a pulley; when the first arm is sleeved on the outside of the second arm, one of the inside of the first arm or the outside of the second arm can be provided with a slide rail, and the other can be provided with a pulley. It can be known that the movement mode between the first connecting member 211 and the first arm, and between the first arm and the second arm is not limited to the sliding mode, and when the sliding mode is adopted, it is not limited to the matching mode of the pulley and the slide rail, and can also be the mode of inner and outer slide rails or other modes that can achieve sliding.

[0066] The movement mode of the first movement mechanism 21 can realize extension and retraction and swing in the first direction, thereby driving the suction mechanism 3 to move closer to or away from the support mechanism 1 .

[0067] Furthermore, the sewage suction pipeline 4 includes a fixed pipe 41, a first sleeve and a second sleeve. The fixed pipe 41 is connected and fixed to the first connecting piece 211, the first sleeve is sleeved with the fixed pipe 41, and the second sleeve is sleeved with the fixed pipe 41; the second sleeve is connected and fixed to the second arm. When the second arm moves along the first arm, the second sleeve is driven to move along the first sleeve, thereby driving the first sleeve to move along the fixed pipe 41.

[0068] Specifically, the fixed tube 41 is sleeved on the outside of the first sleeve, and the first sleeve is sleeved on the outside or inside of the second sleeve. The first sleeve has a fifth position completely located in the fixed tube 41 and a sixth position extending from the fixed tube 41, and the first sleeve can move between the fifth position and the sixth position, or stay at any position between the fifth position and the sixth position; the second sleeve has a seventh position completely located in the first sleeve and an eighth position extending from the first sleeve, and the second sleeve can move between the seventh position and the eighth position, or stay at any position between the seventh position and the eighth position.

[0069] In the initial state, the first sleeve is located at the fifth position and the second sleeve is located at the seventh position. When the first telescopic member 2132 generates a force to drive the second arm to move from the third position to the fourth position, due to the fixed connection relationship between the second arm and the second sleeve, the second sleeve is driven to move from the seventh position to the eighth position; when the second sleeve reaches the eighth position and continues to move in the direction away from the seventh position, it drives the first sleeve to move from the fifth position to the sixth position, thereby realizing the extension of the sewage suction pipeline 4.

[0070] When the first telescopic member 2132 generates a force to drive the second arm to move from the fourth position to the third position, it can drive the second sleeve to move from the eighth position to the seventh position; when the second sleeve reaches the seventh position and continues to move in the direction away from the eighth position, it drives the first sleeve to move from the sixth position to the fifth position, thereby achieving the retraction of the sewage suction pipeline 4.

[0071] Specifically, one of the outer side of the first sleeve or the inner side of the fixed tube 41 may be provided with a slide rail, and the other may be provided with a pulley; when the first sleeve is sleeved on the outer side of the second sleeve, one of the inner side of the first sleeve or the outer side of the second sleeve may be provided with a slide rail, and the other may be provided with a pulley. It can be known that the movement mode between the fixed tube 41 and the first sleeve, and between the first sleeve and the second sleeve is not limited to the sliding mode, and when the sliding mode is adopted, it is not limited to the matching mode of the pulley and the slide rail, and it can also be the mode of inner and outer slide rails or other modes that can achieve sliding.

[0072] Optionally, the sewage suction pipeline 4 is arranged in parallel with the first telescopic component 213 to achieve telescoping and swinging in the first direction.

[0073] Furthermore, the first motion mechanism 21 also includes a second connecting member 2131, a first fixing member 215, a second fixing member and a drag chain 216, the second connecting member 2131 is respectively connected to the ends of the second arm and the second sleeve, the first fixing member 215 is arranged on the second connecting member 2131, the second fixing member is connected and fixed to the first connecting member 211 and is located on the peripheral side of the fixed tube 41, the two ends of the drag chain 216 are respectively connected to the first fixing member 215 and the second fixing member, the second arm and the second sleeve are both connected to the second connecting member 2131; when the first telescopic member 2132 drives the second arm to move, due to the connection and fixing relationship between the second connecting member 2131 and the second arm, the second connecting member 2131 is moved by the force, driving the first fixing member 215 to move in the first direction, thereby pushing or pulling the drag chain 216 to roll to enter or leave the second fixing member.

[0074] Specifically, an oil pipe is provided in the drag chain 216, and the oil pipe is respectively connected to the first telescopic member 2132 and the first swing member 212. When the first telescopic member 2132 is a variable amplitude cylinder and the first swing member 212 is a telescopic cylinder, the oil pipe provides power for both, and the oil pipe can move with the drag chain 216, and the drag chain 216 also plays the role of fixing the oil pipe.

[0075] Furthermore, if Figure 4 and Figure 5 As shown, the second motion mechanism 22 includes: a third connecting member 221 connected to the first motion mechanism 21, a second telescopic assembly connected to the third connecting member 221 at one end and connected to the suction mechanism 3 at the other end, and a second swinging member 223 connected to the third connecting member 221 at one end and connected to the second telescopic assembly at the other end; when the second telescopic assembly moves, it can drive the suction mechanism 3 to approach or move away from the operating surface, and the second swinging member 223 generates a force to drive the second telescopic assembly to swing relative to the first motion mechanism 21. The lifting or swinging of the suction device can be achieved through the extension and contraction of the second telescopic assembly and the swinging of the second swinging member 223, so as to adjust the height position of the suction device in real time to adapt to the thickness of the coal seam; the second swinging member 223 can adjust the horizontal posture of the dust inlet 34 of the suction device relative to the operating surface in real time.

The telescopic arm has a ninth position completely located in the fixed arm 222 and a tenth position almost completely extended from the fixed arm 222. When the second telescopic member drives the telescopic arm to move from the ninth position to the tenth position, it can drive the suction mechanism 3 to approach the operating surface; when the second telescopic member drives the telescopic arm to move from the tenth position to the ninth position, it can drive the suction mechanism 3 away from the operating surface. It can be understood that the second telescopic member can drive the telescopic arm to stay at the ninth position, the tenth position, or any position between the ninth position and the tenth position.

[0077] Specifically, the movement mode between the telescopic arm and the fixed arm 222 includes but is not limited to sliding, telescopic, etc. When the sliding mode is adopted, a pulley can be provided on one of the outer side of the telescopic arm and the inner side of the fixed arm 222, and a slide rail can be provided on the other. Of course, the inner slide rail and the outer slide rail can also be used. There is no limitation here. As long as the sliding mode can be achieved, it belongs to the scope of the present application.

[0078] Furthermore, if Figure 6 and Figure 7 As shown, the suction mechanism 3 includes a suction pipe 31, a cleaning member 32, a power member 33 and a dust inlet 34. The suction pipe 31 is connected to the sewage suction pipeline 4; the power member 33 drives the cleaning member 32 to rotate to clean the dirt, particles, etc. in the contact area of ​​the cleaning member 32 on the operating surface. The suction pipe 31 generates negative pressure to drive the dirt rolled up by the cleaning member 32 into the suction pipe 31 through the dust inlet 34, and enter the dust removal system of the railway tunnel cleaning vehicle through the sewage suction pipeline 4. The dust removal system removes the particles to the conveyor belt after processing. Among them, the cleaning member 32 can be a roller brush, a cleaning brush, a rag, etc., which is not limited here; the power member 33 can be a device with driving force such as a motor or an electric motor.

[0079] Specifically, a fan is also provided on the suction pipe 31. The negative pressure generated by starting the fan acts on the suction pipe 31 to form a negative pressure air duct in the suction pipe 31, which is convenient for sucking away dust, particulate matter, etc. During negative pressure pneumatic transportation, the local resistance of the pipeline can be reduced to avoid pipe blockage.

[0080] Optionally, the fixed pipe 41 is connected to the railway tunnel cleaning vehicle through a first connecting pipe, and the second sleeve is connected to the dust outlet of the suction pipe 31 through a second connecting pipe, and both the first connecting pipe and the second connecting pipe are flexible pipes that can be extended and retracted. The first connecting pipe and the second connecting pipe can both be corrugated pipes to achieve flexible connection between the fixed pipe 41 and the railway tunnel cleaning vehicle, and between the second sleeve and the dust outlet of the suction pipe 31.

[0081] Furthermore, if Figure 8As shown, the side suction device also includes a locking mechanism 5 arranged on the support mechanism 1, and the locking mechanism 5 includes a cylinder 51, a support seat 52, a limiter 53 and a moving member 54. The support seat 52 is fixed on the support mechanism 1, and the cylinder 51 is fixed on the support seat 52. The output end of the cylinder 51 is connected to one end of the moving member 54, and the other end of the moving member 54 is provided with a limiter 53; the cylinder 51 generates a force that is transmitted to the moving member 54 through the output end to drive the moving member 54 to move, so as to move the limiter 53. The limiter 53 can be a structure with a limiting function such as a limiter plate or a limiter buckle. The suction mechanism 3 and the limiter plate can be connected by clamping, magnetic attraction or snap connection, etc., which is not limited here.

[0082] Specifically, there are two sets of locking mechanisms 5, and the two sets of locking mechanisms 5 are respectively arranged on both sides of the support mechanism 1. When the suction mechanism 3 approaches the support mechanism 1, the limiting members 53 of the two sets of support mechanisms 1 are respectively moved toward the direction close to the suction mechanism 3 by the force and clamp the suction mechanism 3. It can be understood that when the limiting members 53 are limiting plates, when the suction mechanism 3 enters the space between the two limiting plates, the suction mechanism 3 is clamped by the two limiting plates to achieve locking.

[0083] Furthermore, the support mechanism 1 includes a first support member 11 and a second support member 12, the first support member 11 is installed on the railway tunnel cleaning vehicle, the second support member 12 is arranged at the upper end of the first support member 11, and the angle between the extension line of the second support member 12 and the extension line of the first support member 11 is greater than 90°. One end of the first swing member 212 is fixedly connected to the second support member 12, and the other end is connected to the first connecting member 211.
