Description

Technical Field

[0001] This utility model relates to the field of road repair technology, and in particular to an asphalt pavement recycling and repair device. Background Technology

[0002] In the field of road construction, asphalt pavement is the main paving form of high-grade highways due to its advantages such as good driving comfort, low noise, strong adaptability to roadbed deformation, and convenient and quick maintenance. However, asphalt pavement materials have high porosity and poor temperature stability, aging resistance, and smoothness retention, making asphalt pavement prone to damage. Timely maintenance and repair of asphalt pavement can extend its service life and maximize the economic benefits throughout its entire life cycle.

[0003] Currently, road joint repairs commonly use hot recycling repair machines. The equipment is heated and positioned at the joint to soften the old material. Modified emulsified asphalt is then sprayed to enhance adhesion, new asphalt mixture is filled in, and finally, small compaction equipment is used to compact it into shape. However, when constructing in mountainous areas, the roadbed is narrow and the road surface is uneven, making it difficult for large repair equipment to pass, resulting in difficulties in repairing the joints. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an asphalt pavement recycling and repair device, which aims to improve the problem that the narrow roadbed and uneven road surface in mountainous areas make it difficult for large repair equipment to pass, resulting in difficulties in repair.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an asphalt pavement recycling and repair device, comprising a top plate, a heating mechanism provided at the bottom of the top plate for heating the pavement, a hydraulic rod provided on the top surface of the top plate, and an angle adjustment mechanism provided at the bottom of the hydraulic rod for adjusting the angle of the heating mechanism;

[0006] The heating mechanism includes a movable component, which is disposed at the four corners of the bottom surface of the top plate. The bottom surface of the hydraulic rod is provided with a housing, and the inner wall of the housing is provided with a heating component. The outer wall of the housing is slidably connected with a limit baffle, and the top of the limit baffle is provided with an elastic component. The outer wall of the housing is fixedly connected with multiple connecting ears.

[0007] As a further description of the above technical solution:

[0008] The angle adjustment mechanism includes a mounting plate, the top surface of which is fixedly connected to the bottom surface of the hydraulic rod, a mounting plate fixedly connected to the bottom of the mounting plate, a rotating plate rotatably connected to the bottom surface of the mounting plate, a fixed plate fixedly connected to the bottom surface of the mounting plate, a power assembly provided on the outer wall of the fixed plate, a support rod assembly provided on the outer side of the power assembly, a fixed block rotatably connected to the other end of the support rod assembly, and one end of the fixed block fixedly connected to the top surface of the rotating plate.

[0009] As a further description of the above technical solution:

[0010] The movable component includes a support leg, the top surface of which is fixedly connected to the bottom surface of the top plate, and a pulley is provided on the bottom surface of the support leg.

[0011] As a further description of the above technical solution:

[0012] The heating assembly includes a heating plate, the outer wall of which is fixedly connected to the outer wall of the outer shell, and a heating tube is provided on the top surface of the heating plate.

[0013] As a further description of the above technical solution:

[0014] The elastic component includes a fixed post, which is fixed to the top surface of the limiting baffle, and a spring is provided on the outer wall of the fixed post.

[0015] As a further description of the above technical solution:

[0016] The power assembly includes a motor, which is fixed to the outer wall of the fixed plate, and a threaded rod is fixedly connected to the output end of the motor.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, a heating tube is set on the top of the heating plate. The heating tube makes the heat evenly distributed on the heating plate, effectively avoiding heating blind spots, ensuring that the joint area is fully and evenly heated, and quickly heating the joint to the specified temperature. The limiting baffle can prevent the heat from spreading to unnecessary surrounding areas, concentrate the heat to heat the joint, and the fixing pile and connecting ear limit the displacement of the limiting baffle. The spring allows it to reset after heating is completed.

In this utility model, when the road surface is inclined, the threaded sleeve is displaced by the motor, the threaded sleeve pushes the diagonal brace, and the other end of the diagonal brace is rotatably connected to the top of the rotating plate through the fixed block. The diagonal brace pushes the rotating plate to rotate around one end of the mounting plate. The bottom surface of the rotating plate is fixedly connected to the top surface of the outer shell. When it is necessary to heat the road surface, the hydraulic rod is activated, the hydraulic rod pushes the heating mechanism and the angle adjustment mechanism to move downward. The angle adjustment mechanism adjusts the bottom angle of the heating plate to fit the road surface for heating, ensuring uniform heating. Attached Figure Description
