[0002] Most of the pavements of bridges are now asphalt pavements and concrete pavements, and the bridge pavements need to be frequently maintained during use;

[0003] There are many types of maintenance. When pouring concrete and asphalt, watering maintenance needs to be carried out during the final setting process, that is, heat preservation and moisture preservation. During the use of asphalt pavements, maintenance is also required. For example, when the pavement of a bridge is damaged, the damaged pavement needs to be first cut off, then shoveled off, and finally asphalt repaired;

[0004] However, there is a problem when cutting damaged asphalt bridge pavements. That is, existing road cutters often cut asphalt through cutting wheels. When moving the cutter to the next damaged area, when passing through uneven asphalt pavements, the uneven pavement will contact the cutting wheel, thus causing damage to the cutting wheel.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Please refer to Figures 1-4 , as an embodiment of the present invention, the bridge pavement maintenance device includes a truss 1, and a cutting mechanism is arranged above the truss 1:

[0028] The cutting mechanism includes a cutting blade 12, and the cutting blade 12 is used for cutting the bridge pavement. A contraction mechanism is also arranged above the truss 1;

[0029] The contraction mechanism includes a slide rod 13. The contraction mechanism and the cutting mechanism cooperate with each other. When it is necessary to cut the bridge pavement, the contraction mechanism retracts the slide rod 13. At this time, the cutting blade 12 is exposed to the bottom of the truss 1 to cut the pavement. When it is necessary to protect the cutting blade 12, the contraction mechanism pushes the slide rod 13. At this time, the cutting blade 12 slowly leaves the pavement and retracts to the inside of the truss 1.

[0030] In this embodiment, through the cooperation between the cutting mechanism and the retracting mechanism, when it is necessary to cut the damaged asphalt pavement of the bridge, the retracting mechanism is started, and the sliding rod 13 in the retracting mechanism will slide. At this time, the cutting blade 12 will slowly contact the ground, thereby driving it to cut the asphalt through the cutting mechanism. When it is necessary to move the entire device to other damaged asphalt, the sliding rod 13 will slide in the opposite direction. At this time, the cutting blade 12 will slowly leave the road surface, so that during the movement of the entire device, the cutting blade 12 will gradually retract back, thereby protecting the cutting blade 12.

[0031] As a further solution of the utility model, a motor 2 is fixedly arranged on the top of the truss 1, and a transmission mechanism is arranged at one end of the output shaft of the motor 2.

[0032] In this embodiment, the rotation of the output shaft of the motor 2 drives the transmission mechanism to operate.

[0033] As a further solution of the utility model, the transmission mechanism includes a first pulley 3, a belt strip 4 and a second pulley 5. The first pulley 3 is fixedly arranged at one end of the output shaft of the motor 2. The first pulley 3 and the second pulley 5 are connected by the belt strip 4, and the second pulley 5 cooperates with the cutting mechanism.

[0034] In this embodiment, the output shaft of the motor 2 drives the first pulley 3 to rotate. Similarly, the first pulley 3 drives the second pulley 5 to rotate through the belt strip 4, and the second pulley 5 drives the cutting mechanism to operate.

[0035] As a further solution of the utility model, the cutting mechanism further includes a driving gear 6, a driven gear 7, a round rod 8, a movable rod 10 and a double swing arm assembly;

[0036] The driving gear 6 is fixedly arranged on one side of the second pulley 5, and the driving gear 6 is meshed with the driven gear 7 to drive the driven gear 7 to rotate. The round rod 8 is fixedly arranged on the surface of the driving gear 6 away from the second pulley 5;

[0037] The double swing arm assembly includes a first swing arm 9 and a second swing arm 11, wherein the first swing arm 9 is rotatably connected to the round rod 8, an end of the first swing arm 9 away from the round rod 8 is rotatably connected to a movable rod 10, the movable rod 10 is rotatably connected to the second swing arm 11, the movable rod 10 is fixedly connected to a cutting blade 12, the movable rod 10 is fixedly passed through the cutting blade 12 and is also fixedly connected to the surface of the driven gear 7, and an end of the second swing arm 11 away from the movable rod 10 is rotatably connected to a slide rod 13;

[0038] The round rod 8 is rotatably connected to the truss 1 via a support frame.

[0039] In this embodiment, the second pulley 5 drives the driving gear 6 to rotate. The driving gear 6 meshes with the driven gear 7 and drives the driven gear 7 to rotate. The truss 1 is provided with a support frame to support the round rod 8, and it can be seen from the drawings that the support frame is provided in multiple numbers, so that the driving gear 6 can operate stably;

[0040] It should be noted that the first swing arm 9 makes a circular motion around the axis of the round rod 8. When the sliding rod 13 pulls the second swing arm 11 to move towards the armrest, at this time the second swing arm 11 will pull the movable rod 10. Since the movable rod 10 is fixedly connected to both the cutting blade 12 and the driven gear 7, the movable rod 10 will make a circular motion around the axis of the round rod 8 through the first swing arm 9, that is, drive the cutting blade 12 to retract upwards. At this time, the driven gear 7 will also rotate itself while making a revolution around the axis of the driving gear 6, that is, contract upwards synchronously with the cutting blade 12.

[0041] As a further solution of the present invention, the retracting mechanism further includes a cylinder 14. The cylinder 14 is fixedly arranged on the truss 1, and the output end of the cylinder 14 is fixedly connected to the sliding rod 13. The cylinder 14 is used to push the sliding rod 13 to slide.

[0042] In this embodiment, the output end of the cylinder 14 drives the sliding rod 13 to run back and forth. To sum up, the sliding rod 13 drives the second swing arm 11 to run back and forth, so that the cutting blade 12 can be exposed and retracted. When cutting the road surface is required, the output end of the cylinder 14 retracts, and at this time it drives the sliding rod 13 to approach the cylinder 14. The sliding rod 13 will push the second swing arm 11 towards the cylinder 14, and the second swing arm 11 will drive the cutting blade 12 and the driven gear 7 downwards through the movable rod 10. Similarly, when retracting, only need to extend the cylinder 14 forward.

[0043] As a further solution of the present invention, universal wheels 15 are fixedly arranged at the bottom of the truss 1. The universal wheels 15 are used to turn in any direction.

[0044] In this embodiment, the universal wheels 15 facilitate turning in any direction on the irregular damaged asphalt road surface.

[0045] As a further solution of the present invention, a chute 101 is further opened on one side of the truss 1 close to the cylinder 14, and the sliding rod 13 is inside the chute 101. The sliding rod 13 is slidably matched with the truss 1.

[0046] In this embodiment, the sliding rod 13 runs inside the chute 101 opened on the truss 1, preventing the sliding rod 13 from falling off the truss 1 and ensuring the stable operation of the cutting mechanism.

[0047] As a further solution of the present utility model, the number of the second swing arms 11 is set to two, and the two second swing arms 11 are respectively arranged on the left and right sides of the cutting blade 12.

[0048] In this embodiment, the second swing arms 11 are arranged on both sides to ensure the stable operation of the cutting mechanism.

[0049] The above embodiments are exemplary rather than restrictive. Therefore, without departing from the spirit or basic features of the present utility model, all technical solutions that can implement the present utility model in other specific forms are included in the present utility model.
