Description

Technical Field

[0001] The utility model relates to the technical field of cleaning, in particular to a bridge roadbed and pavement leveling device. Background Art

[0002] The roadbed and pavement structure of a bridge refers to the surface of the base layer laid under the concrete or asphalt layer. This base layer is usually constructed with plain concrete or crushed stone concrete. After the construction is completed, the first step is to carefully level and clean its surface, and then roughen it to enhance the bonding force between the subsequent concrete or asphalt layer and the roadbed to ensure the stability of the structure. Given the special location of the bridge, it is often attacked by strong winds, which may blow surrounding debris to the surface of the newly poured roadbed. Therefore, it is particularly important to level and clean the bridge roadbed in a timely manner to ensure that the quality of the road surface is not affected. When leveling the roadbed, manual or mechanical operations can be selected according to actual conditions. In mechanical leveling, a vibrator is often used to achieve surface leveling through the principle of vibration. Although it can effectively improve the flatness of the roadbed surface, it is powerless when dealing with attachments such as plastic bottles, small iron blocks and other foreign objects. These foreign objects may not be effectively removed, thus limiting the comprehensiveness of mechanical leveling. In contrast, although manual cleaning can handle these attachments more carefully, it may not be as efficient as mechanical operations, and the operation is more cumbersome. Utility Model Content

[0049] As a further solution of the utility model, driving wheels 10 are fixedly arranged on both sides of the main shaft 6, and the driving wheels 10 cooperate with the slag collecting mechanism;

[0050] The slag collecting mechanism also includes a driven wheel 11, a first swing arm 13, a second swing arm 14 and a secondary shaft 15. The driving wheel 10 is meshed with the driven wheel 11. The first swing arm 13 is rotatably set on the main shaft 6. The two driven wheels 11 are fixedly connected to the secondary shaft 15. The second swing arm 14 is rotatably connected to the secondary shaft 15, and the secondary shaft 15 is fixedly connected to the slag scraping assembly 12.

[0051] In this embodiment, the main shaft 6 drives the driving wheel 10 to rotate, the driving wheel 10 drives the driven wheel 11 to rotate, and the driven wheel 11 drives the scraper assembly 12 to rotate through the secondary shaft 15, so that the scraper assembly 12 can roll the broken slag into the inside of the slag collecting box 29;

[0052] A first swing arm 13 and a second swing arm 14 are also provided so that the secondary shaft 15 can move while rotating.

[0053] As a further solution of the utility model, an adjustment mechanism is further provided at one end of the second swing arm 14;

[0054] The adjusting mechanism includes a longitudinal rod 16, a movable block 17, a fixed block 18, a compression spring 19 and a telescopic rod 20. The longitudinal rod 16 is rotatably connected to the second swing arm 14. A sliding groove for the longitudinal rod 16 to slide is provided on the truss 1, and the longitudinal rod 16 and the truss 1 are slidably matched.

[0055] In this embodiment, when the longitudinal rod 16 moves in the slide groove of the truss 1, the cooperation of the second swing arm 14 and the first swing arm 13 can drive the secondary shaft 15 to move, thereby driving the scraper assembly 12 to adjust its position. When encountering relatively hard debris, the scraper assembly 12 can adjust and give way so that the debris can be better rolled into the interior of the slag collection box 29.

[0056] As a further solution of the utility model, one end of the longitudinal rod 16 away from the second swing arm 14 is rotatably connected to a movable block 17, a telescopic rod 20 is fixedly provided on the surface of the movable block 17, and a fixed block 18 is also provided on the truss 1.

[0057] In this embodiment, when the scraper assembly 12 encounters a relatively large and hard material, the hard debris will squeeze the scraper assembly 12, and the scraper assembly 12 will move upward. When the scraper assembly 12 moves upward, the driven wheel 11 is still engaged with the driving wheel 10, that is, the driven wheel 11 will move upward around the driving wheel 10 while rotating. Similarly, the secondary shaft 15 will also move upward, thereby driving the second swing arm 14 to squeeze the longitudinal rod 16, and the longitudinal rod 16 will drive the movable block 17 to squeeze the compression spring 19, so that the compression spring 19 stores a certain amount of reset elastic potential energy. Under the elastic potential energy of the compression spring 19 reset, the movable block 17 brings the longitudinal rod 16 to squeeze the second swing arm 14, so that the secondary shaft 15 and the scraper assembly 12 are constantly reset according to actual conditions;

[0058] That is, when encountering relatively large and hard debris, the scraper assembly 12 will give way upward, thereby increasing the distance between the soft film of the scraper assembly 12 and the debris collection box 29, so that the soft film can roll the large debris into the interior of the debris collection box 29. After the large debris is rolled in, under the resetting action of the compression spring 19, the scraper assembly 12 returns to the initial position and continues to roll in the debris, and so on, making the scraping effect better.

[0059] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
