Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge engineering, and particularly relates to a pavement compaction device for road and bridge engineering. Background Technique

[0002] Road and bridge engineering refers to the work of survey, design, construction, maintenance, management, etc. of roads and bridges, which can be divided into: subgrade, pavement, bridge, culvert, tunnel, drainage, protection, greening, traffic engineering, mechanical and electrical engineering, etc. During the construction stage of road and bridge subgrade, it is often necessary to lay asphalt on the pavement of the construction project. During the laying process, a pavement compactor is often used to compact the asphalt to improve the flatness of the asphalt pavement.

The utility model provides a pavement compaction device for road and bridge engineering. By moving the threaded rod, the collection box is driven to move to the right, so that the slider slides to the right on the top of the fixed frame, and at the same time, the scraping plate is driven to move to the right. The falling materials can be collected by the collection box.

[0004] However, in the pavement compaction device for road and bridge engineering of this utility model, the eccentric blocks in the pressure roller cannot be adjusted in terms of spacing. The fixed spacing of the eccentric blocks limits the adaptability of the roller to different working conditions and road surface conditions. When compacting roads with different materials and thicknesses, the fixed spacing of the eccentric blocks may not provide the best compaction effect, thus affecting the flatness and density of the road surface. Therefore, a pavement compaction device for road and bridge engineering is proposed to solve the problems raised above. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a pavement compaction device for road and bridge engineering, which has the advantages of strong applicability and easy use, and solves the problem that the eccentric blocks in the pressure roller cannot be adjusted.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a pavement compaction device for road and bridge engineering, including a compaction device body for road and bridge engineering, and the compaction device body is composed of a machine body, a pressure roller frame, a road roller, moving wheels, connecting arms, two eccentric blocks and a rotating shaft;

[0007] An adjusting mechanism for adjusting the distance between two eccentric blocks is arranged inside the rotating shaft. The adjusting mechanism includes a double-shaft motor installed inside the rotating shaft, adjusting lead screws fixedly installed on two output shafts of the double-shaft motor, and sliders slidably installed inside the rotating shaft and threadedly connected to the adjusting lead screws.

[0009] Furthermore, the connecting arm is welded to one side of the roller frame and fixedly connected to the power equipment on the machine body. The road roller is rotatably installed on the roller frame through a rotating shaft.

[0010] Furthermore, the two adjusting lead screws are arranged with opposite threads, so that the two eccentric blocks move relatively or away from each other, and the separated ends of the two adjusting lead screws are connected to the inner wall of the road roller through bearings.

[0011] Furthermore, an installation frame is installed on the side of the roller frame away from the machine body through bolts. The spray pipe and the water tank are respectively fixedly installed on the front and back sides of the installation frame, and the pump housing is fixed on the upper surface of the roller frame. A communication pipe communicating with the spray pipe and the water tank is connected to the outside of the pump housing.

[0012] Furthermore, a volume chamber is formed inside the pump housing, and both communication pipes communicate with the volume chamber. The driving gear and the driven gear are meshed with each other and rotatably installed inside the volume chamber.

[0016] Compared with the prior art, the utility model provides a road surface compaction device for road and bridge engineering, and has the following beneficial effects:

[0017] 1. The roadbed and bridge engineering pavement compaction device can adjust the vibration distribution of the rotating shaft by adjusting the distance between the eccentric blocks, changing the exciting force generated by the eccentric blocks during rotation, making the vibration energy more uniform or concentrated in a specific area, so as to achieve more effective compaction according to the characteristics of different subgrade materials and compaction requirements, with the advantages of strong applicability and easy use, and solving the problem that the eccentric blocks in the pressing roller cannot be adjusted.

[0018] 2. When the road roller of the roadbed and bridge engineering pavement compaction device rotates, the driving gear rotates through the linkage structure. The driving gear rotates and meshes with the driven gear, and uses the gear pump principle to extract the water in the water tank and convey it through the connecting pipe, and finally sprays it out through the nozzle, which can wet the road surface.

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 5 , a pavement compaction device for a road and bridge project, including a compaction device body 1 for a road and bridge project. The compaction device body 1 is composed of a machine body 101, a roller frame 102, a road roller 103, moving wheels 104, a connecting arm 105, two eccentric blocks 106, and a rotating shaft 107. The connecting arm 105 is welded to one side of the roller frame 102 and fixedly connected to the power equipment on the machine body 101. The road roller 103 is rotatably installed on the roller frame 102 through a rotating shaft. Steel balls are arranged inside the eccentric blocks 106. A driving device for the rotation of the road roller 103 and the rotating shaft 107 is arranged on the roller frame 102. The compaction device body 1 is a conventional device well-known to the public in the prior art, so the specific structural composition and working principle thereof will not be elaborated too much in this text. The moving wheels 104 are rotatably installed on the machine body 101.

[0027] In order to improve the compaction effect, in this embodiment, an adjustment mechanism 2 for adjusting the distance between the two eccentric blocks 106 is arranged inside the rotating shaft 107. The adjustment mechanism 2 includes a dual-axis motor 201 installed inside the rotating shaft 107, adjustment lead screws 202 fixedly installed on the two output shafts of the dual-axis motor 201, and sliders 203 slidably installed inside the rotating shaft 107 and threadedly connected to the adjustment lead screws 202. Guide blocks connected to the inner sides of the eccentric blocks 106 are welded to the outer surfaces of the sliders 203. By adjusting the distance between the eccentric blocks 106, the exciting force generated by the eccentric blocks 106 during rotation can be changed, and the vibration distribution of the rotating shaft 107 can be adjusted, so that the vibration energy is more uniform or concentrated in a specific area, thereby realizing more effective compaction according to the characteristics of different subgrade materials and compaction requirements.

[0028] It should be noted that the two adjustment lead screws 202 are arranged with opposite threads, so that the two eccentric blocks 106 move relatively or away from each other, and the separated ends of the two adjustment lead screws 202 are connected to the inner wall of the road roller 103 through bearings. A battery block is installed inside the rotating shaft 107 to supply power to the dual-axis motor 201. A limiting component for limiting the sliders 203 is arranged inside the rotating shaft 107. Heat dissipation holes are also opened inside the rotating shaft 107.

[0029] To improve the compaction environment, a watering mechanism 3 for use in conjunction with the road roller 103 is provided on the roller frame 102. The watering mechanism 3 includes a water tank 302, a pump housing 303, a spray pipe 304, a driving gear 306, and a driven gear 307. A linkage structure 308 is provided between the pump housing 303 and the road roller 103. On the side of the roller frame 102 away from the machine body 101, a mounting frame 301 is installed by bolts. The spray pipe 304 and the water tank 302 are respectively fixedly installed on the front and rear sides of the mounting frame 301, and the pump housing 303 is fixed on the upper surface of the roller frame 102. A connecting pipe 305 communicating with the spray pipe 304 and the water tank 302 is connected to the outside of the pump housing 303.

[0030] In this embodiment, a volume chamber 3031 is formed in the pump housing 303, and both connecting pipes 305 communicate with the volume chamber 3031. The driving gear 306 and the driven gear 307 are meshed with each other and rotatably installed in the volume chamber 3031. A water level sensor is provided on the water tank 302. The water tank 302 is provided with a water inlet pipe and a drain pipe, and sealing caps are threadedly installed at the ends of the water inlet pipe and the drain pipe.

[0031] Specifically, the linkage structure 308 is composed of a linkage shaft 3081, a synchronous pulley 3082, and a synchronous belt 3083. The number of synchronous pulleys 3082 is two. One of the synchronous pulleys 3082 is fixedly installed at one end of the linkage shaft 3081, and the other end of the linkage shaft 3081 is fixedly connected to the driving gear 306. The other synchronous pulley 3082 is connected to the end of the road roller 103. The synchronous belt 3083 can be disassembled and assembled for transportation after the compaction device body 1 is used up.

[0032] It can be understood that the road roller 103 and the watering mechanism 3 are used synchronously by means of the linkage structure 308, which can wet the road surface. The wet road surface can reduce the friction between the road roller 103 and the road surface, making it easier for the compaction device body 1 to compact the material and improving the flatness and density of the road surface.

[0033] The working principle of the above embodiment is as follows:

[0034] During use, the compactor body 1 moves by means of moving wheels, enabling the road roller 103 to compact the road surface of the road bridge. When the road roller 103 rotates, the drive gear 306 rotates through the linkage structure 308. The rotation of the drive gear 306 meshes with the driven gear 307 to pump the water in the water tank 302 by the gear pump principle and convey it through the connecting pipe 305, and finally spray it out through the spray pipe 304, which can wet the road surface, and at the same time can effectively reduce the flying of dust. Moreover, by driving the adjusting screw 202 by the double-shaft motor 201, the distance between the two eccentric blocks 106 can be adjusted, and the vibration distribution of the rotating shaft 107 can be adjusted, so that the vibration energy is more uniform or concentrated in a specific area, thereby realizing more effective compaction according to the characteristics of different subgrade materials and compaction requirements.

[0035] The installation methods, connection methods or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented. In addition, the electrical components that appear in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can realize the control of the electrical components through simple programming, and the existing publicly disclosed power connection technology also belongs to the common knowledge in this field. Therefore, the specific structural composition and working principle are not described in detail in this embodiment.
