The bridge expansion joint cleaning device is used for cleaning bridge expansion joints.

Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a cleaning device for bridge expansion joints. Background Art

[0002] In municipal roads, bridges can be seen everywhere, such as viaducts, overpasses, etc. Due to the large temperature difference throughout the year, the expansion and contraction of objects will occur. In bridge construction, these factors are often taken into account to increase the service life of the bridge. Therefore, various preset gaps are usually provided in the bridge, and such gaps are usually called bridge expansion joints.

[0003] At present, the cleaning of bridge expansion joints is mainly carried out by inserting the suction head of a vacuum cleaner into the expansion joint to suck out the sundries. However, the sundries in the expansion joint will form lumps over a long time, so the vacuum cleaner cannot effectively suck them out. Content of the Utility Model

A toggle plate is fixed on the drive shaft. The drive shaft is fixed to the output shaft of a drive motor. A vacuum cleaner is fixed on a groove plate at one end of the vehicle frame. The suction pipe of the vacuum cleaner is fixed to a suction head.

[0007] For the cleaning device for bridge expansion joints, the suction head is of a cylindrical tube structure. Screws are fixed at both ends of the suction head. After the screws pass through the sliding holes of the groove plate, they are threadedly connected to fastening nuts.

[0008] For the cleaning device for bridge expansion joints, the toggle plate comprises an annular plate and a back plate. The annular plate is fixed on the back plate. A plurality of cylindrical-arranged insertion holes are formed in the annular plate. A toggle rod is slidably connected in each insertion hole. A fixed ring buckle is fixed on the annular plate through a bolt.

[0009] For the cleaning device for bridge expansion joints, the fixed ring buckle comprises four concentric annular buckles, and the four annular buckles are connected and fixed through a fixing plate.

[0010] For the cleaning device for bridge expansion joints, two limiting shafts are fixed on the toggle rod, and a limiting wheel is rotatably connected to each limiting shaft. Advantageous Effects

[0011] 1. The utility model is provided with a dial plate, and the dial plate is in the structure of a dial tooth, which can break up the caked sundries in the expansion joint, so that they can be effectively sucked out by a vacuum cleaner, ensuring the cleaning effect of the expansion joint.

[0012] 2. The position of the lever of the dial plate of the utility model can be adjusted, so that it can be applicable to different expansion joint depths and improve its applicability. Description of the Drawings

Detailed Embodiment

[0020] Referring to Figures 1 to 6 as shown, a bridge expansion joint cleaning device, which comprises a vehicle frame 5. The vehicle frame is a square ring frame. Four openings 12 are formed on the vehicle frame. Each opening is connected with a wheel through a wheel axle. A handrail 2 is fixed on the vehicle frame for pushing the device to move. The vehicle frame is connected with a drive shaft 11 through a bearing. A dial plate 7 is fixed on the drive shaft. The drive shaft is fixed with the output shaft of a drive motor 6. A vacuum cleaner 1 is fixed on a groove plate 13 at one end of the vehicle frame. The suction pipe 3 of the vacuum cleaner is fixed with a suction head 4.

[0021] During use, the pushing device is moved, and the driving motor drives the dial to rotate clockwise. The dial has a toothed structure, which can break up the lumps in the expansion joint. The sundries after being broken up can be sucked out by the suction head of the vacuum cleaner and sucked into the vacuum cleaner to facilitate the cleaning of the expansion joint.

[0022] For the bridge expansion joint cleaning device described above, the suction head has a cylindrical tube structure. Screws are fixed at both ends of the suction head. After the screws pass through the sliding holes of the groove plate, they are threadedly connected to the fastening nut 10. Through the setting of this sliding hole, since the depths of the expansion joints of different bridges vary, by loosening the fastening nut, the suction head can be slid to change its inserted position, making it applicable to expansion joints of different depths.

[0023] For the bridge expansion joint cleaning device described above, the dial includes an annular plate 71 and a back plate 72. The annular plate is fixed on the back plate. A plurality of cylindrical-arranged insertion holes 79 are formed in the annular plate. A dial rod 73 is slidably connected in each insertion hole. A fixed ring buckle 74 is fixed on the annular plate by bolts. Two limit shafts 78 are fixed on the dial rod, and a limit wheel 77 is rotatably connected to each limit shaft.

[0024] For the bridge expansion joint cleaning device described above, the fixed ring buckle includes four concentric annular buckles 75, and the four annular buckles are connected and fixed by a fixing plate 76.

[0025] The fixed ring buckle has a total of four annular openings, which are concentrically arranged and can adjust the position of the dial rod. As shown in the figure, at this time, the innermost annular buckle is located between the two limit wheels. Loosen the adjusting nut 81. A through-long screw 80 is fixed on the annular plate. The through-long screw passes through the fixing plate and is threadedly connected to the adjusting nut. Then pull out the fixed ring buckle. At this time, adjust the position of each dial rod so that the second annular opening is located between the two limit wheels. Then buckle the fixed ring buckle again. In this way, the adjustment of the position of the dial rod can be realized, making it applicable to the cleaning of expansion joints of different depths.
