[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-5 The present invention provides a technical solution, an integrated cleaning and maintenance device for subway rail transit, including a mobile vehicle 1 that moves along the track and a detection camera 56 for detecting the track, wherein the mobile vehicle 1 is an electric mobile platform.

[0036] The cleaning part 2 includes an outer shell 21 with its top fixed to the front end of the mobile trolley 1, a cleaning roller 22 with two ends of the central axis rotatably mounted on the two side walls of the front end of the outer shell 21, a spiral blade shaft 23 with two ends rotatably mounted on the two side walls of the rear part of the outer shell 21 and the spiral blades on both sides of the center rotating in opposite directions, a transmission member 24 for driving the cleaning roller 22 and the spiral blade shaft 23 to rotate synchronously, and a cylindrical brush 25 rotatably mounted in pairs on the rear wall of the outer shell 21 near the two sides and used for cleaning the side walls of the track, a shovel plate 211 is fixed to the bottom end of the front part of the outer shell 21, and a discharge port 212 is opened on the rear wall of the outer shell 21 corresponding to the center of the spiral blade shaft 23.

[0037] Among them, the cleaning roller 22 is a rotating shaft structure with plastic bristles fixed on the outer peripheral wall, and the spiral blades of the spiral blade shaft 23 are tangent to the rear part of the top surface of the shovel plate 211. A slot 214 is provided at the bottom of the outer shell 21 corresponding to the position of the track, and the paired cylindrical brushes 25 are respectively located on both sides of the slot 214. A horizontal plate 215 extending in the horizontal direction is fixed near the bottom end of the rear wall of the outer shell 21, and the top end of the central axis of the cylindrical brush 25 is rotatably mounted on the horizontal plate 215. The top surface of the horizontal plate 215 is respectively provided with transmission parts 26 for driving the cylindrical brush 25 to rotate near the two ends.

[0038] The storage box 4 is fixed to the rear of the top surface of the mobile trolley 1 , the front end of the scraper conveyor mechanism 3 is fixed to the rear wall of the outer shell 21 corresponding to the discharge port 212 , and the unloading end of the scraper conveyor mechanism 3 is fixed to the top of the front of the storage box 4 .

[0039] The detection frame 5 is arranged at the rear end of the mobile vehicle 1. The detection frame 5 includes an arc-shaped guide rail 541 located above the track and a moving member 55 that slides back and forth along the arc-shaped guide rail 541 at the bottom. The rear wall at the bottom of the moving member 55 is respectively fixed with a detection camera 56.

[0040] In summary, the mobile trolley 1 carries the entire device and moves along the subway track. The front cleaning roller 22 can cover the width of the track. The shovel plate 211 is made of wear-resistant plastic material, has a certain elasticity, and the front end is arranged in a comb shape. The transmission member 24 drives the cleaning roller 22 and the spiral blade shaft 23 to rotate synchronously. The cleaning roller 22 cleans the garbage on the surface of the subway track and moves to the direction of the spiral blade shaft 23. The spiral blade shaft 23 transfers the garbage to the discharge port 212, so that the garbage is transported from the discharge port 212 to the storage box 4 by the scraper conveying mechanism 3.

[0041] At the same time, the transmission member 26 drives the cylindrical brush 25 to rotate at a high speed. The bristles of the cylindrical brush 25 are metal wires, so as to clean the rust and attachments on both sides of the rail.

[0042] The detection camera 56 realizes semi-circular detection of the rail under the fixed support of the moving part 55. The detection camera 56 is arranged to be slightly inclined toward the rear side, so that when the detection camera 56 performs semi-circular movement on the upper side of the rail, the detection range can cover the entire rail. In addition, the rail is cleaned before the detection camera 56 detects the rail, so the detection effect is improved.

[0043] Since dust is easily generated during the rust removal of the rails and the cleaning of the track lines, dust removal management is required. Side holes 213 are respectively opened at the bottom of the rear end of the two side walls of the outer shell 21 corresponding to the position of the cylindrical brush 25, and dust hoods 8 with suction ports facing inward are respectively installed in the side holes 213. A vacuum pump 6 is provided at the front of the top of the mobile trolley 1, and the input end of the vacuum pump 6 is connected to the outlet of the dust hood 8 through a pipeline. That is, the vacuum pump 6 and the dust hood 8 are used to facilitate the removal of dust generated at the rails, thereby ensuring the detection effect of the detection camera 56.

The transmission member 26 includes a transmission box body 2 261 fixed to the top surface of the horizontal plate 215 and having two power output shafts respectively connected to the top of the central shaft of the cylindrical brush 25, and a motor 2 262 fixed to the top surface of the transmission box body 261 and having a power output shaft connected to the power input shaft of the transmission box body 261. Among them, the transmission box body 1 241 and the transmission box body 2 261 can be belt driven, chain driven or gear driven, so that a single shaft can synchronously drive two shafts.

[0046] See also Figure 4-7 The detection frame 5 also includes a fixed vertical plate 51 whose top end is fixed to the rear end of the moving vehicle 1, a bracket 54 fixedly connected to the bottom end of the rear wall of the fixed vertical plate 51 and used to fix and support the arc guide rail 541, and a power mechanism for driving the moving member 55 to slide back and forth along the arc guide rail 541.

[0047] Among them, the rear wall of the fixed vertical plate 51 is fixed with grooves 512 extending in the horizontal direction in pairs, and a linkage frame 52 that slides back and forth in the horizontal direction is arranged between the two grooves 512. The two ends of the linkage frame 52 are respectively provided with support rods 522, and the rear wall of the support rod 522 is sleeved with a short shaft 523. The moving member 55 includes a rectangular frame 551 that slides along the arc-shaped guide rail 541 and a connecting plate 552 fixed to the front end of the top of the rectangular frame 551. The center of the connecting plate 552 is provided with a sliding groove 553 that is matched with the short shaft 523 in a sliding engagement in the vertical direction, and the detection camera 56 is fixed to the middle of the rear wall of the rectangular frame 551. That is, when the linkage frame 52 slides back and forth horizontally, the connecting plate 552 is pushed and pulled by the short shaft 523, so that the connecting plate 552 drives the rectangular frame 551 to slide back and forth along the arc-shaped guide rail 541.

[0048] Specifically, the fixed vertical plate 51 is provided with an axial hole 511 at the middle position between the two slots 512, and the motor 3 57 is installed at the position corresponding to the axial hole 511 on the front wall of the fixed vertical plate 51. After the power output shaft of the motor 3 57 passes through the axial hole 511, a driving wheel 53 is fixedly mounted thereon. The outer peripheral wall of the driving wheel 53 is provided with a half-circle of teeth. The linkage frame 52 also includes a frame 521 whose top and bottom parts are respectively slidably connected to the slots 512 in the horizontal direction, and the ends of the support rod 522 are respectively fixed to the two ends of the frame 521. The top and bottom surfaces of the inner cavity of the frame 521 are respectively provided with racks 524 that mesh with the teeth on the driving wheel 53. That is, the motor 3 57 drives the driving wheel 53 to rotate, and the teeth on the outer peripheral wall of the driving wheel 53 are alternately meshed with the racks 524 on the top and bottom of the inner cavity of the frame 521, thereby realizing the horizontal reciprocating sliding of the frame 521.

[0049] In order to reduce frictional resistance and improve the smoothness of movement, a plurality of groove wheels 513 are rotatably installed in the groove body 512 and are rollingly engaged with the top and bottom of the frame body 521. Groove wheels 554 are rotatably installed on the upper and lower sides of the middle of the inner cavity of the rectangular frame 551, and the inner and outer edges of the arc guide rail 541 correspond to the groove wheels 554 for rolling engagement.
