DETAILED DESCRIPTION

[0030] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0032] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0033] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0034] The present application is further described below with reference to the accompanying drawings:

[0035] like Figures 1 to 11 As shown, the present application provides an intelligent trestle cleaning system, which is applied to a trestle channel 1 with a height difference. In the present application, the trestle channel 1 is generally used to accommodate and support a coal conveying trestle 2, including a guiding device 3, a traction device 4 and a cleaning device 5. The guiding device 3 is laid on the top of the trestle channel 1, making full use of the upper space of the trestle channel 1, without affecting the normal operation of the coal conveying trestle 2 and the normal passage of the staff. The traction device 4 is arranged at the higher end of the trestle channel 1, and the cleaning device 5 is movably arranged on the guiding device 3. The traction device 4 and the cleaning device 5 are connected. The traction device 4 is suitable for towing the cleaning device 5 and making the cleaning device 5 move at least along the length direction of the trestle channel 1. The cleaning device 5 is suitable for flushing the trestle channel 1.

[0036] When the traction device 4 releases the traction force, the cleaning device 5 can move toward the lower side of the trestle channel 1 along the length direction of the trestle channel 1 under the influence of gravity. When the traction device 4 is pulling, the cleaning device 5 can move toward the higher side of the trestle channel 1 along the length direction of the trestle channel 1. Since the coal dust and dust in the coal conveying trestle 2 are large, if a motor or other equipment is used to control the cleaning device 5, the motor is prone to failure and the maintenance cost is high. Therefore, combining the guiding device 3, the traction device 4 and the cleaning device 5 can reduce the driving structure and effectively reduce the driving difficulty of the cleaning device 5.

[0037] Among them, Figure 4 and 5 As shown, the guiding device 3 includes a track changing mechanism 32 and a plurality of guide rails 31 arranged at intervals along the width direction of the trestle channel 1. The ends of two adjacent guide rails 31 are suitable for being connected close to each other to form a track changing section 33. The track changing mechanism 32 is arranged at the track changing section 33. The track changing mechanism 32 is suitable for switching the cleaning device 5 entering the track changing section 33 between the two guide rails 31. It can be understood that the track changing mechanism 32 can enable the cleaning device 5 to enter different guide rails 31, so as to obtain different cleaning trajectories in the trestle channel 1. Due to the obstruction of the coal conveying trestle 2 in the trestle channel 1 and the support column 11 that may be set, the cleaning device 5 with a single cleaning trajectory has a poor cleaning effect on the trestle channel 1 and there are many cleaning dead angles. The guiding device 3 after applying the track changing mechanism 32 can help the cleaning device 5 plan the cleaning trajectory and achieve a higher cleaning coverage rate. The cleaning device 5 on the guide rail 31 connected by the track changing mechanism 32 only needs a single traction device 4 to achieve traction, and there is no need to set more traction devices 4, thereby effectively reducing the system complexity and control layout cost.

[0038] It is worth noting that although the present application limits the guide rail 31 to be along the length direction of the trestle channel 1, in fact, as long as the height difference can be continuously generated on the path of the guide rail 31 to drive the cleaning device 5 to move continuously, the shape of the guide rail 31 can be optimized according to the actual cleaning path, and the track changing mechanism 32 switches different guide rails 31 in the width direction of the trestle channel 1 is only a preferred choice for the present application.

[0039] like Figure 5In the illustrated embodiment, the track changing mechanism 32 comprises a track changing branch rail 321 and a flipper 322. The track changing branch rail 321 is arranged in the track changing section 33. The track changing branch rail 321 and the flipper 322 are connected. The flipper 322 is suitable for controlling the flipping of the track changing branch rail 321 and cooperating with one of the guide rails 31. In the present application, the guide rail 31 is a double-track track. The tracks will approach each other in the track changing section 33. The two inner tracks will cross and be interrupted, while the two outer tracks will continue to extend and approach each other. The control end of the track changing branch rail 321 is located at the cross and interruption of the two inner tracks. The movable end of the track changing branch rail 321 can be flipped relative to the control end and cooperating with one of the two outer tracks, thereby guiding the cleaning device 5 to obtain different guide rails 31.

[0040] like Figure 6 In the illustrated embodiment, the flipper 322 includes a displacement channel 3221 and a flipping channel 3222. The track-changing branch rail 321 is suitable for moving along the displacement channel 3221, moving to one side to disengage from the guide rail 31 and then entering the flipping channel 3222. The track-changing branch rail 321 is suitable for re-entering the displacement channel 3221 after flipping in the flipping channel 3222, and cooperating with one of the guide rails 31. The above-mentioned movement process can be achieved by setting a driving motor and a conventional transmission structure. The purpose of such a design is that the flipping action of the flipper 322 has less impact on the structure of the guide rail 31, and can make the connection between the two guide rails 31 more compact, so as to avoid the cleaning device 5 from getting stuck or derailing at the intersection of the two inner rails as much as possible.

[0041] like Figure 7 and 8 In the embodiment shown, at least one set of guide wheels 511 is provided on both sides of the cleaning device 5, the guide rail 31 includes a first sub-rail 311 and a second sub-rail 312, and the first sub-rail 311 and the second sub-rail 312 are provided with opposite guide grooves 313, the guide wheel 511 includes a first guide wheel portion 5111 and a second guide wheel portion 5112, the first guide wheel portion 5111 is adapted to move in the guide groove 313, and the second guide wheel portion 5112 is adapted to move along both sides of the guide groove 313, and when the track change support rail 321 is engaged with one of the guide rails 31, at least the guide groove 313 is enabled. The two sides of 13 are connected, the first guide wheel portion 5111 plays a role in stabilizing the movement along the guide rail 31, and the second guide wheel portion 5112 plays a role in guiding the first guide wheel portion 5111. When the track is changed, the guide groove 313 may be disconnected, but it is only necessary to ensure that the two sides of the guide groove 313 are connected, the second guide wheel portion 5112 can move along the two sides of the guide groove 313 along the guide rail 31, and help the first guide wheel portion 5111 to smoothly pass the track change position. This design can achieve higher track change stability between the cleaning device 5 and the guiding device 3.

[0042] like Fig. 9 and10 In the illustrated embodiment, the cleaning device 5 includes a movable seat 51 and a cleaning arm 52. The movable seat 51 is suitable for being movably connected to the guide rail 31. The cleaning arm 52 is movably arranged on the movable seat 51. A cleaning assembly is arranged at the movable end of the cleaning arm 52. The cleaning arm 52 is suitable for being unfolded relative to the movable seat 51 so that the cleaning assembly moves toward the bottom direction of the pier channel 1.

[0043] In some embodiments, guide wheels 511 are arranged on both sides of the moving seat 51, and a driving motor is arranged on the moving seat 51. One end of the cleaning arm 52 is rotatably connected to the moving seat 51. The driving motor can drive the cleaning arm 52 to rotate, so that the cleaning arm 52 rotates close to the top of the pier channel 1 to be folded, or rotates close to the bottom of the pier channel 1 to be unfolded. By setting the length of the cleaning arm 52, the cleaning component on the cleaning arm 52 can be cleaned at the middle height position of the pier channel 1, thereby improving the cleaning effect.

[0044] like Fig. 9 and 10 In the illustrated embodiment, the cleaning component includes at least one cleaning nozzle 521, and the cleaning nozzle 521 is provided with a plurality of cleaning rollers 5211 along the circumferential direction. A plurality of cleaning nozzles 5212 are provided along the length direction on the same side of the cleaning rollers 5211. The cleaning nozzles 5212 are suitable for spraying water and driving the cleaning nozzle 521 to rotate. The cleaning component is configured in a non-powered cleaning form, which can reduce the structural complexity and cost. It only needs to pass through a pressurized water flow and let the pressurized water flow be sprayed out from the cleaning nozzle 5212. The cleaning nozzle 521 can automatically rotate under the pressure of the water flow, thereby achieving comprehensive cleaning. At the same time, the pressurized water flow can also improve the cleaning effect.

[0045] like Figure 2 In the illustrated embodiment, when the cleaning arm 52 is unfolded relative to the movable seat 51, the plane where the cleaning nozzle 521 is located is parallel to the cross-section of the pier channel 1. When the cleaning device 5 moves along the guide device 3, the cleaning nozzle 521 can pass through the entire pier channel 1, thereby achieving overall cleaning of the pier channel 1.

[0046] like Fig. 9 and 10 In the illustrated embodiment, there are multiple cleaning nozzles 521. When there are two cleaning nozzles 521, the cleaning nozzle 5212 of at least one cleaning nozzle 521 is inclined away from the other cleaning nozzle 521, which can increase the cleaning coverage area of ​​the cleaning component, improve the cleaning efficiency, and save water resources.

[0047] like Fig. 9 and 10In the illustrated embodiment, there are multiple cleaning nozzles 521, and the cleaning nozzles 5212 on different cleaning nozzles 521 are located on different sides of the cleaning roller 5211, so that the cleaning nozzles 521 are suitable for rotating clockwise or counterclockwise when spraying water. For example, one cleaning nozzle 521 rotates clockwise and the other cleaning nozzle 521 rotates counterclockwise, which can effectively deal with cleaning dead corners. At the same time, multi-directional water flow can have a better cleaning effect on dust.

[0048] like Figure 2 In the illustrated embodiment, the traction device 4 includes a winding mechanism 41 and a water supply pipe 42, and both ends of the water supply pipe 42 are respectively connected to the winding mechanism 41 and the cleaning device 5, and the winding mechanism 41 is suitable for winding and retracting the water supply pipe 42 so that the cleaning device 5 is close to or away from the winding mechanism 41. By winding the water supply pipe 42, the remote activity control of the cleaning device 5 can be achieved, and the winding mechanism 41 can be arranged outside the trestle channel 1, thereby reducing the occupation of the space of the trestle channel 1, avoiding pollution by coal dust, improving the operation stability, and reducing the generation of cleaning dead corners.

[0049] In some embodiments, the traction device 4 is connected to a water supply device for supplying water to the water supply pipe 42 , and a pressure pump may also be provided to help increase the pressure of the water flow.

[0050] like Figure 5 and 11 In the illustrated embodiment, one or more pipe racks 6 are provided on the side of the guide rail 31 along the length direction, and a pipeline rack 61 is provided on the pipe rack 6. The pipeline rack 61 is suitable for being unfolded or folded when the cleaning device 5 passes by. When unfolded, the pipeline rack 61 is suitable for supporting the water supply pipe 42. The pipeline rack 61 can limit the sagging of the water supply pipe 42, thereby reducing the occupation of the space below the trestle channel 1 and reducing the length of the water supply pipe 42 that needs to be released when the cleaning device 5 travels to the other end of the guide rail 31, thereby reducing the system load.

[0051] In some embodiments, a pipe rack motor is provided on the pipe rack mechanism 6, and the pipe rack motor is rotatably connected to the pipeline rack 61. The pipe rack motor is suitable for controlling the rotation of the pipeline rack 61. This solution can perform individual control, remote control and linkage control on the pipe rack mechanism 6, and has better control freedom.

[0052] like Fig.11 In the illustrated embodiment, a linkage arm 62 is provided on the pipe rack mechanism 6, and the linkage arm 62 is fixedly connected to the pipeline rack 61 and is suitable for rotating relative to the guide rail 31. When the cleaning device 5 moves from the higher side to the lower side of the trestle passage 1, the linkage arm 62 is suitable for contacting the cleaning device 5 before the pipeline rack 61, and then the cleaning device 5 drives the pipeline rack 61 to rotate to the water supply pipe 42 through the linkage arm 62, so as to support the water supply pipe 42. This solution does not require a driving device, has a simple structure, is easy to arrange, and is not prone to failure.

[0053] like Figure 5 In the illustrated embodiment, a buffer device 7 is provided at the lower end of the guide rail 31 located at the pier channel 1. The buffer device 7 is suitable for limiting the separation of the cleaning device 5 from the end of the guide rail 31. The buffer device 7 can prevent the cleaning device 5 from rushing out of the guide rail 31 due to excessive speed, or avoid collision and damage with the wall at the end of the pier channel 1, thereby improving safety and stability.

[0054] In some embodiments, the buffer device 7 can be a cylinder buffer or a spring buffer.

[0055] like Figure 4 In the illustrated embodiment, a conveying device is arranged below the trestle passage 1, and a guide rail 31 is located on one side or both sides of the conveying device. In the present application, the conveying device is generally a coal conveying trestle 2, and guide rails 31 are arranged on both sides of the coal conveying trestle 2 and are connected by a track changing section 33, which can effectively eliminate cleaning dead corners and improve the cleaning effect.

[0056] like Figure 4 In the illustrated embodiment, support columns 11 are arranged in the pier channel 1, and guide rails 31 are located on one side or both sides of the support columns 11. Guide rails 31 are arranged on both sides of the support columns 11 and are connected by a track change section 33, so that the cleaning device 5 can avoid the support columns 11 and clean both sides of the support columns 11, which can effectively eliminate cleaning dead corners and improve the cleaning effect.
