Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a roadbed compacting device. Background Art

[0002] The roadbed is the foundation of a track or road surface. It is a geotechnical structure formed by excavation or filling. When building a road, a roller is needed to compact the earth. Existing rollers all use rollers to roll the road. The roller is installed on the frame of the roller. A vibration mechanism is arranged inside the roller. During the rolling process of the roller, the vibration mechanism inside the roller drives the roller to vibrate, thereby compacting and flattening the road surface.

[0003] Since the pressure of the drum on the ground is huge, the dirt will adhere to the surface of the drum. The existing solution is to install a scraper on the frame. The scraper rests against the surface of the drum. As the drum rotates, the scraper scrapes off the adhesion on the surface of the drum. Although this method can effectively remove the material on the surface of the drum, friction will occur between the scraper and the drum, and the service life is not high. Utility Model Content

[0004] In order to solve the problems mentioned in the background technology, the purpose of the utility model is to provide a roadbed compacting device.

[0005] In order to achieve the above objectives, the technical solution of the utility model is:

[0006] A roadbed compaction device comprises a U-shaped frame, a roller is installed between the two side arms of the frame, and hanging plates are movably arranged on both sides of the axial direction of the roller on the outside of the frame, and at least three shafts parallel to the roller are fixedly connected to the side of the hanging plate facing the roller, and multiple shafts located on the same hanging plate are evenly arranged around the circumference of the roller, and rollers are rotatably installed on the ends of the shafts, and the rollers are in contact with the inner wall of the wheel shell of the roller. An arc-shaped scraper is detachably installed between the two hanging plates, and the scraper is arranged at the front end of the frame and is located obliquely below the roller, and the scraper is clearance-matched with the outer wall of the wheel shell of the roller.

[0007] Furthermore, two limit rods are fixedly connected to the side of the hanging plate facing the drum, and the two limit rods on the same hanging plate are respectively arranged on the upper and lower sides of the side arms of the frame. An anti-slip block is detachably connected to the limit rod, and the side arms of the frame are clamped between the hanging plate and the anti-slip block.

[0008] The beneficial effects of the utility model are as follows: under the action of the hanging plate and multiple rollers, no matter how the drum shakes, the distance between the scraper and the wheel shell of the drum is constant, so the mud on the surface of the wheel shell of the drum can be effectively scraped off, and because the scraper and the wheel shell of the drum are clearance-matched, the scraper will not wear out quickly, effectively extending the service life of the scraper; and the scraper is arranged at the front end of the frame, so that the drum can just press the scraped mud back onto the road surface.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.

[0014] Example

[0015] like Figure 1-Figure 3As shown, a roadbed compacting device includes a U-shaped frame 1, a roller 2 is installed between the two side arms of the frame 1, and hanging plates 3 are movably arranged on both sides of the axial direction of the roller 2 on the outside of the frame 1. Four shafts 31 parallel to the roller 2 are fixedly connected to the side of the hanging plate 3 facing the roller 2. The four shafts 31 located on the same hanging plate 3 are evenly arranged around the circumference of the roller 2. A roller 32 is rotatably installed at the end of the shaft 31. The roller 32 is in conflict with the inner wall of the wheel shell of the roller 2. An arc-shaped scraper 4 is detachably installed between the two hanging plates 3. Preferably, both ends of the scraper 4 in the length direction are welded with connecting blocks 41, and the connecting blocks 41 are connected by Bolts and nuts are fixed on the hanging plate 3, the scraper 4 is arranged at the front end of the frame 1 and is located obliquely below the drum 2. The scraper 4 is matched with the outer wall of the wheel shell of the drum 2 with a gap of 0.2 cm. Two limit rods 33 are fixedly connected to the side of the hanging plate 3 facing the drum 2. The two limit rods 33 located on the same hanging plate 3 are respectively arranged on the upper and lower sides of the side arms of the frame 1. The limit rods 33 are threadedly connected with anti-slip blocks 34. The side arms of the frame 1 are clamped between the hanging plate 3 and the anti-slip blocks 34. Under the action of the limit rods 33 and the anti-slip blocks 34, the hanging plate 3 can be prevented from rotating to a large extent, and the hanging plate 3 can be prevented from moving along the axial direction of the drum 2.

[0016] The frame 1 and the drum 2 are conventional components of a road roller, and their principles are not described in detail. When in use, the frame 1 is mounted on the body of the road roller, and the drum 2 is pushed forward by the body. During the forward movement of the drum 2, the eccentric vibration mechanism inside the drum 2 drives the drum 2 to vibrate, thereby compacting the earth. Under the action of the hanging plate 3 and multiple rollers 32, no matter how the drum 2 vibrates, the distance between the scraper 4 and the wheel shell of the drum 2 is constant, so the soil on the surface of the wheel shell of the drum 2 can be effectively scraped off, and because the scraper 4 and the wheel shell of the drum 2 are clearance-matched, the scraper 4 will not wear out quickly, effectively extending the service life of the scraper 4; and the scraper 4 is arranged at the front end of the frame 1, so that the drum 2 can just press the scraped soil back on the road surface.

[0017] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. All modifications, equivalent substitutions, improvements, etc. within the spirit and principles of the present invention should be included in the protection scope of the present invention.
