[0025] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a road surface pre-cleaning device for bridge construction, comprising:

[0027] Mounting frame 1;

[0028] Two fixing frames 4 are both rotatably mounted on the mounting frame 1 and are respectively located on the sides of the mounting frame 1 to form an angle. The two fixing frames 4 are both provided with a cleaning brush 13. One end of the cleaning brush 13 is connected to a driver 12 for driving the cleaning brush 13 to rotate; and

[0029] The adjusting assembly includes two rotating members connected to the two fixing frames 4 and an adjusting member disposed between the two rotating members. The adjusting member is used to drive the two rotating members to rotate synchronously so as to increase or decrease the angle between the two fixing frames 4.

[0030] In the embodiment of the utility model, two cleaning brushes 13 are respectively carried by two fixing frames 4, and the cleaning brushes 13 are driven by the rotation of the driver 12 to perform cleaning work, and the angle area between the two cleaning brushes 13 is cleaned, and the two fixing frames 4 can be rotated on the mounting frame 1, so under the cooperation of the adjustment component, the adjustment member can be moved on the mounting frame 1, so that the angle between the two fixing frames 4 can be changed. When the angle between the two becomes smaller, the cleanable area between the two cleaning brushes 13 can be reduced, and the angle between the two fixing frames 4 can be increased, so that the angle between the two fixing frames 4 is increased, so that the cleanable area between the two cleaning brushes 13 is increased, which is suitable for cleaning roads of different widths, and does not need to replace other cleaning devices, saving costs and shortening construction period. The above-mentioned driver 12 is a driving motor.

[0031] Based on the above scheme, if Figure 1 and Figure 3 As shown, the rotating member is a gear 15, the rotating shaft of the fixing frame 4 passes through the mounting frame 1 and is connected to the gear 15, the adjusting member includes a telescopic rod 18 provided on the mounting frame 1 and a toothed plate 14 connected to the telescopic end of the telescopic rod 18, the toothed plate 14 is located between the two gears 15 and meshes with the two gears 15.

[0032] Specifically, when the angle between the two fixing frames 4 is adjusted by the cooperation of the rotating member and the adjusting member in the adjusting assembly, the telescopic rod 18 is started to extend the telescopic end of the telescopic rod 18, so that the tooth plate 14 moves between the two gears 15, and the gears 15 on both sides of the tooth plate 14 are synchronously driven to rotate through the cooperation of the teeth, so that the gears 15 drive the corresponding fixing frames 4 to rotate, thereby reducing the angle between the two cleaning brushes 13 and reducing the cleanable area. When the telescopic end of the telescopic rod 18 is retracted, the angle between the two cleaning brushes 13 can be increased to increase the cleanable area, and the stop position can be achieved when the telescopic rod 18 stops moving. The telescopic rod 18 can be any one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder.

[0033] Specifically, Figure 3 As shown, the tooth plate 14 is provided with a T-block 16, and the mounting frame 1 is provided with a T-slot 17 for the T-block 16 to slide and engage. The tooth plate 14 is limited by the T-block 16 and the T-slot 17, which can not only position the tooth plate 14, but also prevent the telescopic end of the telescopic rod 18 from being subjected to radial force.

[0034] Specifically, Figure 1 As shown, a sliding block 5 corresponding to two fixing frames 4 is slidably provided on the mounting frame 1, and the sliding block 5 passes through the mounting frame 1 and is connected to the fixing frame 4. The connection with the fixing frame 4 through the sliding block 5 increases the force points of the fixing frame 4, and ensures the stability of the fixing frame 4 during use and adjustment. In addition, the sliding block 5 is provided with a pulley 11, and the mounting frame 1 is provided with a slide groove 10 for the pulley 11 to slide. The sliding block 5 is slidably supported by the pulley 11, which reduces the friction between the sliding block 5 and the mounting frame 1 and improves the transmission efficiency.

[0035] like Figure 1 As shown, it also includes a supporting frame 2 and a screw rod 8 rotatably arranged on the supporting frame 2 . A driving block 19 is arranged on the mounting frame 1 , and the driving block 19 is transmission-connected with the screw rod 8 .

[0036] In the embodiment of the utility model, under the action of the carrier frame 2, the carrier frame 2 can be installed at the rear end and bottom end of the mobile equipment, so that the mobile equipment drives the two cleaning brushes 13 to perform mobile operations. When it is installed on the mobile equipment and no operation is required, the screw rod 8 is rotated to make the screw rod 8 rotate on the carrier frame 2, so that the mounting frame 1 moves upward under the action of the driving block 19, thereby separating the cleaning brush 13 from the road surface to avoid unnecessary wear. When it is used again in the future, the screw rod 8 is reversed to slowly drive the mounting frame 1 to descend, so that the cleaning brush 13 contacts the ground.

[0037] Specifically, Figure 1As shown, the support frame 2 is provided with a limiting rod 7, and the mounting frame 1 is sleeved on the limiting rod 7. The limiting rod 7 can be used to limit the mounting frame 1, which not only ensures the stability of the mounting frame 1 when in use, but also facilitates the adjustment of the mounting frame 1 through the screw rod 8. In addition, the support frame 2 is provided with a hand wheel 6, and the screw rod 8 passes through the support frame 2 and is connected to the hand wheel 6, and the screw rod 8 can be conveniently adjusted manually through the hand wheel 6.

[0038] Specifically, the support frame 2 is provided with a plurality of mounting holes 3 for bolts to pass through, and the bolts can be passed through the mounting holes 3 and installed on the mobile equipment. The detachable design facilitates disassembly for easy maintenance.

[0039] Specifically, a reinforcing rod 9 is connected between the mounting frame 1 and the driving block 19 , and the force points at the outermost edge of the mounting frame 1 are connected through the reinforcing rod 9 to ensure the stability of the mounting frame 1 in use.

[0040] In summary, the present invention can adjust the angle between the two fixed frames 4 by cooperating with each other through the telescopic rod 18, the tooth plate 14 and the two gears 15 in the adjusting assembly, thereby adjusting the range of the angle area between the two cleaning brushes 13, and can clean roads of different widths. The impurities attached to the road surface can be separated by the cleaning brush 13. In actual use, a negative pressure collection device can be installed on the mobile equipment to correspond to the angle between the two cleaning brushes 13, so as to adsorb and collect the cleaned impurities and dust. Moreover, after being fixedly installed on the mobile equipment through the supporting frame 2, the height of the cleaning brush 13 from the ground can be adjusted by the action of the screw rod 8 to facilitate subsequent continued use.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
