Technical Field

[0001] This utility model relates to the field of road compaction technology, specifically to an asphalt concrete road compaction and leveling device. Background Technology

[0002] Asphalt concrete, commonly known as asphalt concrete, is typically made by manually selecting aggregates with a specific gradation, such as crushed stone or crushed gravel, stone chips or sand, and mineral powder, and mixing them with a certain proportion of road asphalt material under strictly controlled conditions. Asphalt concrete can be divided into two main categories based on the binder used: petroleum asphalt and coal tar pitch.

[0003] Currently, asphalt concrete pavement paving is mostly done by pavers. However, the compaction rollers on existing asphalt concrete pavers are of fixed size and difficult to adjust. Sometimes, when the width of the asphalt concrete pavement is narrow, using longer rollers for compaction occupies a lot of space. Therefore, an asphalt concrete pavement compaction and leveling device is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an asphalt concrete pavement compaction and leveling device to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an asphalt concrete pavement compaction and leveling device, comprising a base plate, two vertical plates fixedly connected to the bottom outer surface of the base plate, a rotating shaft rotatably connected between the two vertical plates, a motor fixedly installed on the outer surface of one of the vertical plates, a fixed roller fixedly sleeved on the outer surface of the rotating shaft, two adjusting roller sleeves provided on both sides of the outer surface of the rotating shaft located on the fixed roller, adjusting sleeves fixedly connected to both sides of the outer surface of the two adjusting roller sleeves, side plates fixedly connected to the upper and lower outer surfaces of the adjusting sleeves, a first connecting hole opened on the outer surface of the two side plates, a first screw provided in the corresponding first connecting hole of the two side plates, and a first nut threaded on the outer surface of the first screw.

[0006] Furthermore, the interior of the fixed roller is hollow, and the outer surface of the fixed roller is provided with a plurality of first through holes. The outer surface of the fixed roller is provided with a second through hole outside the first through holes. A sealing cap is threadedly connected to the interior of the first through holes. The sealing cap is located at the second through hole, and the outer surface of the sealing cap is provided with a plum blossom groove.

[0007] Furthermore, hydraulic rods are fixedly installed at the four corners of the bottom of the base plate, and the output end of the hydraulic rods is fixedly connected to a mounting plate. The outer surface of the mounting plate is equipped with casters.

[0008] Furthermore, two blocking sleeves are provided on the outer surface of the rotating shaft to the side of the adjusting roller.

A second screw is provided in the corresponding second connecting hole of the connecting plate. A second nut is threaded on the outer surface of the second screw.

[0009] Furthermore, slots adapted to the adjusting sleeve and side plate are provided on both sides of the fixed roller.

[0010] Furthermore, rectangular bars are fixedly connected to the upper and lower outer surfaces of the rotating shaft, and rectangular grooves that match the rectangular bars are opened inside the fixed roller, adjusting roller sleeve, adjusting sleeve and blocking sleeve.

[0011] Furthermore, the number of the first and second through holes is four, and they are arranged in a linear array.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to the following: Figures 1-4 This utility model provides a technical solution: an asphalt concrete pavement compaction and leveling device, including a base plate 1, two vertical plates 2 fixedly connected to the bottom of the base plate 1, a rotating shaft 3 rotatably connected between the two vertical plates 2, a fixed roller 5 sleeved on the rotating shaft 3, and an adjusting roller sleeve 6 provided at both ends of the fixed roller 5, and the adjusting roller sleeve 6 sleeved on the rotating shaft 3; an adjusting sleeve 7 fixedly connected to both ends of the adjusting roller sleeve 6; the outer diameter of the adjusting sleeve 7 is adapted to the inner diameter of the fixed roller 5, so that the adjusting sleeve 7 is embedded in the slot 10 of the fixed roller 5.

[0022] Furthermore, the adjusting roller sleeve 6 includes two arc-shaped roller sleeves, and the adjusting sleeve 7 includes two arc-shaped sleeves. Both ends of any arc-shaped roller sleeve are fixed with arc-shaped roller sleeves. The arc-shaped sleeves are provided with side plates 8, and the side plates 8 are provided with first connecting holes. When the two arc-shaped roller sleeves are arranged opposite each other, the side plates of the two arc-shaped sleeves located at the same end are arranged opposite each other, so that the two first connecting holes are connected. The first connecting holes are used to lock the two arc-shaped roller sleeves through the first screw 9. More specifically, the outer surface of the first screw 9 is threaded with a first nut for locking the two arc-shaped roller sleeves to form the adjusting roller sleeve 6.

[0023] Furthermore, in this embodiment, the interior of the fixed roller 5 is hollow, specifically as follows: Figure 3 As shown in the slot 10, the end of the fixed roller 5 is provided with a slot that is adapted to the side plate 8. The slot is connected to the slot 10, so that the adjusting sleeve 7 can be inserted into the slot of the fixed roller 5 to connect the fixed roller 5 and the adjusting sleeve 6.

[0024] Furthermore, two blocking sleeves 14 are provided between the adjusting roller sleeve 6 and the vertical plate 2. Each blocking sleeve 14 is fixedly connected to a connecting plate 15, and the connecting plate 15 has a second connecting hole. The two blocking sleeves 16 are arranged opposite each other so that the two second connecting holes are connected. The two blocking sleeves 14 are locked by passing the second screw 16 through the two second connecting holes in sequence and by locking the two blocking sleeves 14 with the second nut. Specifically, the two blocking sleeves 14 are put on the rotating shaft 3, and the two connecting plates 15 are connected by the second screw 16 and the second nut, thereby installing the two blocking sleeves 14 on the rotating shaft 3. The blocking sleeves 14 block and fix one side of the adjusting roller sleeve 6 to prevent the adjusting roller sleeve 6 from sliding.

[0025] Furthermore, a rectangular strip 17 is fixedly connected to the outer surface of the rotating shaft 3. The fixed roller 5, adjusting roller sleeve 6, adjusting sleeve 7 and blocking sleeve 14 are all provided with rectangular grooves that are adapted to the rectangular strip 17. Specifically, when the rotating shaft 3 rotates, it drives the rectangular strip 17 to rotate, so that the rectangular strip 17 drives the adjusting sleeve and adjusting sleeve 7 on the rotating shaft 3 to rotate, so as to avoid the adjusting sleeve and adjusting sleeve 7 from being unable to rotate due to sliding force.

[0026] Furthermore, hydraulic rods 11 are fixedly installed at the four corners of the bottom of the base plate 1. The output end of the hydraulic rods 11 is fixedly connected to the mounting plate 12. The outer surface of the mounting plate 12 is equipped with movable wheels 13. Specifically, when no compaction work is being carried out, the mounting plate 12 is driven by the hydraulic rods 11, so that the movable wheels 13 contact the ground, which facilitates the movement of the device.

[0027] Furthermore, the outer surface of the fixed roller 5 is provided with several mounting through holes, and the mounting through holes are threadedly connected to a sealing cover 18, the outer surface of which is provided with a plum blossom groove.

[0028] In this embodiment, the mounting through hole is formed by two interconnected first through holes and second through holes. Specifically, the fixed roller 5 has several first through holes on its circumference, and the second through holes are located outside the first through holes. The first through holes have threads inside for connecting the sealing cover 18, so that the sealing cover 18 is located at the second through hole. The outer surface of the sealing cover 18 has a perforated groove. Specifically, by aligning a screwdriver with the perforated groove on the sealing cover 18, the sealing cover 18 is rotated and removed. Water is then poured into the fixed roller 5 to adjust the pressure on the road surface. When compaction is not required, the sealing cover 18 is unscrewed to drain the water from the fixed roller 5, reducing the overall weight of the device and facilitating subsequent movement of the device.

[0029] Furthermore, the number of mounting holes is four, arranged in a linear array.

[0030] Furthermore, a motor 4 is provided at one end of the rotating shaft 3. The motor 4 is fixed to one of the vertical plates 2, and the motor 4 drives the rotating shaft 3 to rotate.

[0031] In this invention, the motor 4 drives the rotating shaft 3 to rotate, which in turn drives the fixed roller 5 to rotate. The fixed roller 5 moves on the asphalt concrete pavement, thereby compacting the asphalt concrete pavement. Depending on the size of the asphalt concrete pavement, the adjusting roller sleeve 6 can be installed or removed. During installation, the adjusting roller sleeve 6 is placed on the surface of the rotating shaft 3 so that the two side plates 8 correspond. The two side plates 8 are connected by the first screw 9 and the first nut, thereby fixing the two adjusting roller sleeves 6. Then, the adjusting sleeve 7 near the fixed roller 5 is inserted into the slot 10 to connect the fixed roller 5 and the adjusting roller sleeve 6, thus enabling the compaction of larger asphalt concrete pavements. During disassembly, the above steps are reversed to compact smaller asphalt concrete pavements, thereby facilitating the flexible adjustment of the rolling range of the equipment according to the width of the asphalt concrete pavement and reducing the space occupied by the pressure roller.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
