Description

Technical Field

[0001] This invention relates to the field of train carriage cleaning equipment technology, and in particular to a cleaning suction nozzle for a train carriage cleaning vehicle. Background Technology

[0002] Coal plants, power plants, steel mills, and other enterprises need to purchase large quantities of lumpy or powdered raw materials, such as coal and ore, for their production and operation. These raw materials are generally transported by train. After unloading from the train cars, residual material remains on the inner walls of the cars and needs to be cleaned.

[0003] In the relevant existing technology, the cleaning equipment enters the carriage through a cleaning box. Brushes are set on the left and right sides of the cleaning box to clean the side walls of the carriage. At the same time, two negative pressure suction pipes are set in the width direction of the cleaning box and move back and forth. The residual material is sucked out through the suction nozzle at the bottom of the negative pressure suction pipe. The suction nozzle structure of the carriage cleaning vehicle is generally one of three types: double round straight pipe to single round straight pipe suction nozzle, double round oblique pipe to single round pipe suction nozzle, and inverted cone single pipe suction nozzle.

[0004] During the cleaning process, one of three types of suction nozzles is usually selected: double-round straight pipe to single-round straight pipe suction nozzle, double-round inclined pipe to single-round pipe suction nozzle, and inverted cone single pipe suction nozzle. However, a single suction nozzle is difficult to simultaneously handle the large-area cleaning of the carriage floor and the precise cleaning of corners, requiring frequent adjustments to the position of the cleaning vehicle, which further reduces cleaning efficiency. In addition, the edges on both sides of the carriage are at right angles, and neither right-angle suction nozzles nor cone suction nozzles can clean the right-angle edges. At this time, it is necessary to switch to a cleaning vehicle with an inclined pipe suction nozzle for secondary cleaning; otherwise, there will be omissions in the cleaning. The three different suction nozzles are difficult to coordinate in the cleaning of the carriage, and thus it is difficult to handle the cleaning and suction work of different areas and conditions in the carriage. Therefore, a cleaning suction nozzle for a train carriage cleaning vehicle is proposed to solve the above problems. Summary of the Invention

[0008] Preferably, both sides of the connecting plate are fixedly connected to a rotating shaft, and the connecting plate rotates on the side plate via the rotating shaft. One end of the rotating shaft passes through the side plate and the control box in sequence, and is fixedly connected to the inside of the switching worm gear.

[0009] Preferably, the reciprocating sweeping drive device includes a limiting frame seat, the surface of which is fixedly connected to the surface of the vehicle body.

[0011] Preferably, a limiting base is fixedly connected to the vehicle body, a limiting slide rod is fixedly connected inside the limiting base, and the movable support slides on the limiting slide rod.

[0012] Preferably, the tilt drive device includes a connecting base, the surface of which is fixedly connected to the surface of the vehicle body, a tilt control motor is fixedly connected to one side of the connecting base, the output shaft of the tilt control motor is fixedly connected to a key shaft, and a power transmission device is provided on the key shaft.

[0013] Preferably, the end of the key shaft is rotatably connected to the connecting base, and the surface of the key shaft is provided with a keyway.

[0015] Preferably, the end of the connecting rod passes through the movable support and the protective seat in sequence, and is fixedly connected to the transmission worm gear, wherein the protective seat is fixedly connected to the movable support.

[0016] The present invention has the following beneficial effects: 1. In this invention, by fixing the upper suction nozzle, tilting the lower suction nozzle, and two sets of semi-conical suction nozzles, and cooperating with the suction nozzle switching device, flexible switching between different cleaning modes can be achieved. The tilting drive device drives the tilting lower suction nozzle to rotate, replacing the traditional inclined tube suction nozzle, and overcoming the problem of the fixed tilt angle of the traditional inclined tube suction nozzle, achieving a flexible adjustment effect for the suction nozzle tilt angle. Simultaneously, the angle-adjustable tilting lower suction nozzle and the two sets of semi-conical suction nozzles, in conjunction with the suction nozzle switching device, achieve the coordinated cleaning effect of straight tube, conical tube, and inclined tube suction nozzles, thus meeting the working requirements of adapting to the conditions inside the vehicle compartment. The reciprocating cleaning drive device drives the three-tube suction nozzle coordinated device to reciprocate along the width of the vehicle body, achieving large-area cleaning without frequent adjustments to the sweeper's position, significantly improving cleaning efficiency.

[0017] 2. In this invention, when the switching control motor starts, it drives the double-headed worm gear to rotate. The double-headed worm gear drives the switching worm wheels on both sides to rotate synchronously. The switching worm wheels drive the rotating shaft to rotate, which in turn drives the connecting plate and the semi-conical suction nozzle to rotate around the rotating shaft, realizing the synchronous opening and closing of the two sets of semi-conical suction nozzles. When the semi-conical suction nozzle is fully open, the open suction nozzle at the bottom of the inclined suction nozzle forms a large area of ​​suction, which is suitable for cleaning large areas of the vehicle floor. When the semi-conical suction nozzle is fully closed, the tips of the two sets of semi-conical suction nozzles form a precise suction port, which is suitable for cleaning small areas such as corners and crevices in the vehicle.

[0018] 3. In this invention, when the tilt control motor starts, it drives the key shaft to rotate. The key shaft drives the power transmission device to rotate the connecting rod. The connecting rod drives the lower movable ring plate to rotate, which in turn drives the tilted lower suction nozzle to rotate around the connecting rod. Since the fixed upper suction nozzle and the movable support are fixedly connected through the upper fixed ring plate, and the fixed upper suction nozzle and the tilted lower suction nozzle are connected through a corrugated pipe, the flexibility of the corrugated pipe can adapt to the angle adjustment of the tilted lower suction nozzle, thereby realizing the adjustment of the overall tilt angle of the three-tube suction nozzle collaborative device. By adjusting the tilt angle, the suction nozzle can better fit the different angles of the vehicle floor, improving the adsorption effect. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1-3The present invention provides an embodiment of a cleaning suction nozzle for a train carriage cleaning vehicle, comprising a carriage body 1; a telescopic suction pipe 2, which is mounted on the carriage body 1; and a three-pipe suction nozzle coordination device 3, which is mounted at the end of the telescopic suction pipe 2. The three-pipe suction nozzle coordination device 3 includes a fixed upper suction nozzle 31, the top end of which is fixedly connected to the bottom end of the telescopic suction pipe 2, and a corrugated pipe 37 fixedly connected to the bottom end of the fixed upper suction nozzle 31. An inclined lower suction nozzle 32 is fixedly connected to the bottom end of the corrugated pipe 37. The corrugated pipe 37 has good flexibility, enabling it to adapt to the angle adjustment of the inclined lower suction nozzle 32 while ensuring the continuity of the suction channel. Two sets of symmetrical side plates 33 are fixedly connected to the inclined lower suction nozzle 32. The inner surface of the side plates 33... The unit is rotatably connected to a connecting plate 34, on which a semi-conical suction nozzle 35 is fixedly connected. A suction nozzle switching device 36 is provided on the inclined downward suction nozzle 32. By setting up a three-tube suction nozzle coordination device 3, including a fixed upper suction nozzle 31, an inclined downward suction nozzle 32, and two sets of semi-conical suction nozzles 35, and in conjunction with the suction nozzle switching device 36, different cleaning modes can be flexibly switched. When large-area cleaning is required, the two sets of semi-conical suction nozzles 35 are controlled to open, and large-area adsorption is achieved through the fixed upper suction nozzle 31 and the inclined downward suction nozzle 32. When cleaning small areas such as corners and crevices of the vehicle compartment is required, the semi-conical suction nozzles 35 are controlled to close, and precise adsorption is achieved through the tip of the semi-conical suction nozzles 35, which effectively improves the targeting and comprehensiveness of cleaning and avoids cleaning omissions. The cleaning effect of switching between straight and conical suction nozzles can be achieved without replacing the cleaning vehicle body 1, realizing the purpose of the straight and conical suction nozzles working together; the reciprocating cleaning drive device 4 is installed on the vehicle body 1 and is used to drive the three-tube suction nozzle coordinating device 3 to move back and forth along the width of the vehicle body 1; the tilting drive device 5 is installed on the vehicle body 1 and is used to drive the three-tube suction nozzle coordinating device 3 to rotate and tilt. The tilting drive device 5 drives the tilting suction nozzle 32 to rotate, replacing the traditional inclined tube suction nozzle. This overcomes the problem of a fixed tilt angle in traditional inclined tube suction nozzles, allowing for flexible adjustment of the nozzle's tilt angle. Combined with the flexible connection of the corrugated pipe 37, it can adapt to different ground slopes, corners, and debris distribution conditions inside the vehicle, ensuring the nozzle maintains the optimal suction angle with the cleaning surface and improving suction efficiency. By controlling the angle of the tilting suction nozzle 32, the straight and inclined tube states at the bottom of the nozzle can be switched, achieving a synergistic effect between the straight and inclined tube suction nozzles. Simultaneously, the angle-adjustable tilting suction nozzle 32 and two sets of semi-conical suction nozzles 35, in conjunction with the suction nozzle switching device 36, achieve a coordinated cleaning effect using straight, conical, and inclined tube suction nozzles, thus meeting the work requirements of the vehicle interior. The reciprocating cleaning drive device 4 drives the three-tube suction nozzle coordination device 3 to reciprocate along the width of the vehicle body 1, enabling large-area cleaning without frequent adjustments to the sweeper's position, significantly improving cleaning efficiency.

[0023] Reference Figures 4-7 The nozzle switching device 36 includes a control box 361, which is fixedly connected to the tilted nozzle 32. A switching control motor 362 is fixedly connected to the control box 361. The control box 361 adopts a waterproof and dustproof structure to prevent debris and dust from entering the interior and affecting the operation of the components during cleaning. A double-headed worm gear 363 is fixedly connected to the output shaft of the switching control motor 362. A switching worm wheel 364 is meshed on the surface of the double-headed worm gear 363. A rotating shaft 341 is fixedly connected to both sides of the connecting plate 34, and the connecting plate 34 rotates on the side plate 33 through the rotating shaft 341. The transmission ratio between the switching worm wheel 364 and the double-headed worm gear 363 is set according to the opening and closing angle requirements of the semi-conical nozzle 35 to ensure that the semi-conical nozzle 35 can be accurately opened and closed to the preset angle. One end of the rotating shaft 341 passes through the side plate 33 and the control box 361 in sequence and is fixedly connected to the interior of the switching worm wheel 364. When the switching control motor 362 starts, it drives the double-headed worm gear 363 to rotate. The double-headed worm gear 363 drives the switching worm wheels 364 on both sides to rotate synchronously. The switching worm wheels 364 drive the rotating shaft 341 to rotate, which in turn drives the connecting plate 34 and the semi-conical suction nozzle 35 to rotate around the rotating shaft 341, realizing the synchronous opening and closing of the two sets of semi-conical suction nozzles 35. When the semi-conical suction nozzle 35 is fully open, the suction nozzle opening at the bottom of the inclined suction nozzle 32 forms a large area of ​​suction, which is suitable for cleaning large areas of the vehicle floor. When the semi-conical suction nozzle 35 is fully closed, the tips of the two sets of semi-conical suction nozzles 35 form a precise suction opening, which is suitable for cleaning small areas such as corners and crevices in the vehicle.

[0024] Reference Figure 8The reciprocating cleaning drive device 4 includes a limiting frame 41, the surface of which is fixedly connected to the surface of the vehicle body 1. A drive motor 42 is fixedly connected to one side of the limiting frame 41. An adjusting rod 43 is fixedly connected to the output shaft of the drive motor 42. A movable support 44 is threadedly connected to the surface of the adjusting rod 43. A fixed ring plate 45 is fixedly connected to the movable support 44. The interior of the limiting frame 41 is a hollow rectangular structure to guide the movement of the movable support 44. A connecting rod 46 is rotatably connected to the movable support 44 below the fixed ring plate 45. A lower movable ring plate 47 is fixedly connected to the end of the connecting rod 46. The end of the adjusting rod 43 is rotatably connected to the limiting frame 41. The surface of the movable support 44 is slidably connected to the inner wall of the limiting frame 41. The limiting frame 41 limits the movement direction of the movable support 44 to prevent the movable support 44 from moving in the wrong direction. When a displacement occurs, the fixed ring plate 45 is fixed on the fixed upper suction nozzle 31, and the lower movable ring plate 47 is fixed on the inclined lower suction nozzle 32. When the drive motor 42 starts, it drives the adjusting rod 43 to rotate. The adjusting rod 43 drives the movable support 44 to move back and forth along the limiting frame 41 and the limiting slide rod 49 through the threaded transmission. The movable support 44 drives the three-tube suction nozzle coordination device 3 to move back and forth synchronously, realizing a large-area cleaning along the width direction of the vehicle body 1. The limiting base 48 is fixedly connected to the vehicle body 1, and the limiting slide rod 49 is fixedly connected inside the limiting base 48. The limiting slide rod 49 is set parallel to the adjusting rod 43. The bottom of the movable support 44 is provided with a sliding hole. The movable support 44 slides on the limiting slide rod 49 through the sliding hole. The limiting slide rod 49 further improves the stability of the movement of the movable support 44 and avoids the movable support 44 from tilting or getting stuck due to uneven force during the movement.

[0025] Reference Figure 8 The tilt drive device 5 includes a connecting base 51, the surface of the connecting base 51 is fixedly connected to the surface of the vehicle body 1, a tilt control motor 52 is fixedly connected to one side of the connecting base 51, a key shaft 53 is fixedly connected to the output shaft of the tilt control motor 52, a power transmission device 54 is provided on the key shaft 53, the end of the key shaft 53 is rotatably connected to the connecting base 51, and a keyway is provided on the surface of the key shaft 53. When the tilt control motor 52 starts, it drives the key shaft 53 to rotate. The key shaft 53 drives the power transmission device 54 to drive the connecting rod 46 to rotate. The connecting rod 46 drives the lower movable ring plate 47 to rotate, which in turn drives the tilted lower suction nozzle 32 to rotate around the connecting rod 46. Since the fixed upper suction nozzle 31 and the movable support 44 are fixedly connected by the upper fixed ring plate 45, and the fixed upper suction nozzle 31 and the tilted lower suction nozzle 32 are connected by the corrugated pipe 37, the flexibility of the corrugated pipe 37 can adapt to the angle adjustment of the tilted lower suction nozzle 32, thereby realizing the adjustment of the overall tilt angle of the three-tube suction nozzle collaborative device 3. By adjusting the tilt angle, the suction nozzle can better fit the different angles of the carriage floor, improving the adsorption effect.

[0026] Reference Figures 9-10 The power transmission device 54 includes a protective seat 541, a transmission worm wheel 542, and a transmission worm 543. The transmission worm 543 is slidably mounted on the key shaft 53. The inside of the transmission worm 543 has a keyway that mates with the keyway on the key shaft 53, enabling a sliding fit between the transmission worm 543 and the key shaft 53. This ensures that the transmission worm 543 can rotate synchronously with the key shaft 53 and slide along the axial direction of the key shaft 53. The outer ring end face of the transmission worm 543 is rotatably connected inside the protective seat 541. The surface of the transmission worm 543 meshes with the surface of the transmission worm wheel 542. The end of the connecting rod 46 passes through the movable support 44 and the protective seat 541 in sequence and is fixedly connected to the transmission worm 543. The protective seat 541 is fixedly connected to the movable support 44. When the tilt control motor 52 is started, it drives the key shaft 53 to rotate. The key shaft 53 drives the transmission worm gear 543 to rotate synchronously. The transmission worm gear 543 drives the transmission worm wheel 542 to rotate. The transmission worm wheel 542 drives the connecting rod 46 to rotate. The connecting rod 46 drives the lower movable ring plate 47 to rotate, thereby achieving the effect of driving the tilted lower suction nozzle 32 to rotate around the connecting rod 46.

[0027] Working principle: When cleaning the train carriage, the opening and closing state of the semi-conical suction nozzle 35 is adjusted by the nozzle switching device 36 according to the cleaning needs of the carriage. The switching control motor 362 is activated, driving the double-headed worm gear 363 to mesh with the switching worm wheel 364. The switching worm wheel 364 drives the connecting plate 34 and the semi-conical suction nozzle 35 to rotate around the rotating shaft 341, achieving synchronous opening and closing of the two sets of semi-conical suction nozzles 35. For large-area cleaning, the semi-conical suction nozzle 35 is fully opened, at which point the open nozzle opening at the bottom of the tilted suction nozzle 32 forms... For large-area suction areas, if precise corner cleaning is required, the semi-conical suction nozzle 35 is completely closed. When the semi-conical suction nozzle 35 is completely closed, the tips of the two sets of semi-conical suction nozzles 35 form a precise suction port, which is suitable for cleaning small areas such as corners and gaps in the vehicle compartment. Subsequently, by starting the drive motor 42 of the reciprocating cleaning drive device 4, the drive motor 42 drives the adjusting rod 43 to rotate, and drives the moving support 44 to reciprocate along the limiting frame 41 and the limiting slide rod 49 through the threaded transmission, thereby driving the three-tube suction nozzle cooperative device 3 to reciprocate and clean along the width direction of the vehicle body 1. Simultaneously, based on the slope and corners of the vehicle floor, the tilt control motor 52 of the tilt drive device 5 is activated. The tilt control motor 52 drives the transmission worm gear 543 to mesh with the transmission worm wheel 542 through the key shaft 53. The transmission worm wheel 542 drives the lower movable ring plate 47 to rotate through the connecting rotating rod 46, thereby driving the tilted lower suction nozzle 32 to rotate around the connecting rotating rod 46. This adjusts the tilt angle of the tilted lower suction nozzle 32, ensuring that the nozzle always maintains the optimal suction angle with the cleaning surface. By controlling the angle of the tilted lower suction nozzle 32, the straight tube and inclined tube states at the bottom of the nozzle are switched, achieving the synergistic effect of the straight tube and inclined tube suction nozzles. At the same time, the angle-adjustable tilted lower suction nozzle 32 and the two sets of semi-conical suction nozzles 35, in conjunction with the suction nozzle switching device 36, achieve the synergistic cleaning effect of straight tube, conical tube, and inclined tube suction nozzles, thus meeting the working requirements of adapting to the conditions inside the vehicle. The reciprocating sweeping drive 4 drives the three-tube suction nozzle coordination device 3 to sweep back and forth along the width of the vehicle body 1, achieving large-area sweeping without frequent adjustments to the position of the sweeper, thus significantly improving sweeping efficiency.
