Description

Technical Field

[0001] The utility model relates to the technical field of track auxiliary equipment, in particular to a subway track cleaning auxiliary tool. Background Art

[0002] Too much dust and impurities on the subway track can easily threaten the safety during driving. Therefore, keeping the subway track clean is an important part of ensuring the safe operation of the subway. However, as the subway operation time increases, the residual garbage and dust in the subway track reach a certain level, which will cause the subway environmental safety alarm and even threaten the safety of subway operation. However, when cleaning the track, the existing track cleaning device uses a suction fan to absorb the dust and impurities in the track. However, this cleaning method cannot effectively clean the impurities that are difficult to absorb and adhere to the inner wall of the track, resulting in poor cleaning effect of the device. The inability to efficiently clean the dust and impurities on the surface of the rail easily increases the workload of the staff. Utility Model Content

[0014] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 7 It is given, including a U-shaped main body 1 with an opening facing downward, a yield groove with an opening facing forward is opened on the front side of the main body 1, a left-right axial rotating shaft 2 is rotatably connected in the yield groove, a cleaning wheel 3 is coaxially arranged on the rotating shaft 2, L-shaped support plates 4 are slidably connected to the left and right sides of the main body 1, the two support plates 4 can slide relative to or away from each other, the front end of the support plate 4 extends into the yield groove and is rotatably connected to the upper and lower axial guide rods 5, a cross-shaped cleaning column 6 is coaxially arranged on the guide rod 5, conical dust suction ports 7 with larger inside and smaller outside are opened on the left and right sides of the main body 1, the openings of the two dust suction ports 7 are opposite to each other, a debris groove 8 with an opening facing upward is opened in the main body 1, and the left and right sides of the debris groove 8 are connected to the outer ends of the dust suction ports 7 through guide tubes 9 respectively.

[0016] In order to facilitate the simultaneous rotation of the cleaning wheel 3 and the cleaning column 6, a main bevel gear 10 is coaxially provided on the upper end of the guide rod 5, and auxiliary bevel gears 11 that can mesh with the main bevel gear 10 on the corresponding side are coaxially provided on the left and right sides of the rotating shaft 2.

[0017] In order to enable the two support plates 4 to slide relative to or away from each other, a fixed plate 12 is slidably connected inside the main body 1 and is located behind the support plate 4 and in the left and right directions. The left and right sides of the fixed plate 12 are respectively provided with inclined grooves 13 with the inner side higher and the outer side lower. The rear side of the support plate 4 is slidably connected to the inclined groove 13 on the corresponding side through an insertion rod 14. An upper and lower axial screw rod 15 is rotatably connected to the main body 1. The screw rod 15 is threadedly connected to the fixed plate 12. The upper end of the screw rod 15 passes through the main body 1 and is coaxially provided with a knob.

[0018] In order to facilitate the generation of continuous negative pressure in the debris groove 8, a rectangular groove is opened in the main body 1 and is located in front of the debris groove 8. The debris groove 8 is connected to the rectangular groove through a circular groove. An air filter 16 is coaxially arranged in the circular groove. A left-right axial motor 17 is arranged in the rectangular groove. A plurality of negative pressure blades 18 located on the left side of the circular groove are coaxially arranged at the output end of the motor 17. An exhaust hole connected to the rectangular groove is opened on the right side of the main body 1.

[0019] In order to enable the motor 17 to drive the rotating shaft 2 to rotate, the right end of the rotating shaft 2 and the output end of the motor 17 are connected via a belt 19 .

[0020] In order to facilitate the main body 1 to slide along the rails and to block the opening of the debris groove 8, a push handle is provided on the upper side of the main body 1, and a protective plate 20 that can block the opening of the debris groove 8 is provided on the upper end of the main body 1.

[0021] When the utility model is in use, the main body 1 is first placed on the rail, and the two cleaning columns 6 are located on both sides of the rail, and then the knob is turned to drive the fixing plate 12 to slide upward along the main body 1 through the screw rod 15, and the fixing plate 12 drives the two supporting plates 4 to slide relatively through the inclined groove 13 and the insertion rod 14. The relative sliding of the two supporting plates 4 drives the main bevel gear 10 to engage with the auxiliary bevel gear 11 on its corresponding side, so that the cleaning column 6 contacts the side wall of the rail, and the cleaning wheel 3 contacts the upper side of the rail.

[0022] When it is necessary to clean the dust on the rails, the motor 17 is first started. The motor 17 rotates to drive the rotating shaft 2 to rotate through the belt 19. The rotating shaft 2 drives the cleaning column 6 and the cleaning wheel 3 to rotate coaxially through the main bevel gear 10 and the auxiliary bevel gear 11, so that the cleaning wheel 3 and the cleaning column 6 can clean the side of the rails. At the same time, the motor 17 drives the negative pressure blade 18 to rotate. Under the action of the negative pressure blade 18, the gas in the rectangular groove is discharged to the outside through the exhaust hole. At this time, the gas in the debris groove 8 flows into the rectangular groove through the circular groove, and under the action of the air filter 16, it can effectively prevent the dust in the debris groove 8 from flowing into the rectangular groove, so that negative pressure is generated in the debris groove 8. Under the action of the negative pressure, the negative pressure absorbs the dust on the surface of the rail into the debris groove 8 through the conduit 9 and the dust suction port 7;

[0023] At the same time, the main body 1 can be pushed to move along the rail by the push handle, and the dust on the surface of the rail can be continuously sucked through the dust suction port 7 during the continuous operation of the motor 17, so as to facilitate the cleaning of the rail. After the rail is cleaned, firstly, the knob is turned to drive the fixing plate 12 to slide downward through the screw rod 15, and the fixing plate 12 drives the two supporting plates 4 to slide along the main body 1 in reverse through the inclined groove 13 and the plug rod 14, and the supporting plate 4 drives the two main bevel gears 10 to no longer mesh with the auxiliary main bevel gear 10, and at the same time, the cleaning column 6 no longer contacts the surface of the rail, and then the main body 1 is removed from the main body 1, and finally the protective plate 20 is pulled out to clean the dust in the debris groove 8 for the next use.

[0024] The utility model has the advantages of simple structure, convenient operation, novel concept and strong practicality. The cleaning column, cleaning wheel, supporting plate, fixing plate and inclined groove are arranged, which not only facilitates to adjust the position of the cleaning column and makes the cleaning column contact with the surface of the rail, but also enables the cleaning column and the cleaning wheel to rotate to clean the residual dust marks on the surface of the rail, thereby improving the cleaning effect of the rail. The debris groove, dust suction port, motor, negative pressure blade and air filter are arranged, which not only facilitates to continuously absorb the dust on the surface of the rail into the debris groove for collection, but also improves the cleaning effect of the rail and reduces the workload of the staff at the same time.
