Description

Technical Field

[0001] The present invention relates to the technical field of pavement repair, in particular to a device and method for measuring pavement deformation during grouting treatment of road damage. Background Art

[0002] With the acceleration of urbanization and the continuous improvement of transportation infrastructure, road construction and maintenance have become crucial components of urban management and transportation security. Over the long term, old pavement surfaces can develop various defects, such as cracks, potholes, looseness, and subsidence, due to factors such as natural aging, vehicle loads, and climate change. These defects not only impact the road's service life and driving comfort but can also lead to traffic accidents, necessitating timely and effective repair.

[0003] Traditional methods for treating old pavement damage rely primarily on manual labor, which is inefficient and labor-intensive. For example, removing old pavement materials typically requires manual labor using shovels or small machinery, while cutting damaged areas requires manual operation of a cutting machine. Unloading and tamping processes are also often performed manually. These methods present the following challenges:

[0004] Low efficiency: Manual operations are slow and cannot meet the needs of large-scale road repairs.

[0005] High labor intensity: Long-term manual operation can easily lead to fatigue, affecting construction quality and efficiency.

[0006] Unstable construction quality: The accuracy and stability of manual operation are limited, making it difficult to ensure the smoothness and density of the repaired road surface.

[0007] Furthermore, most existing pavement repair equipment is single-purpose and can only perform one or a few processes. This requires frequent equipment replacement, increasing construction time and costs. For example, cutting equipment can only be used to cut pavement, unloading equipment can only be used to remove old pavement material, and ramming equipment can only be used to compact the pavement. This decentralized equipment configuration not only reduces construction efficiency but also increases equipment maintenance and management costs.

[0008] Therefore, a road deformation measurement device and method for grouting treatment of road damage are needed to improve the above problems. Summary of the Invention

[0021] A measuring method of a pavement deformation measuring device for grouting treatment of road damage comprises the following steps:

[0022] Step 1: Moving and positioning the device:

[0023] The device is moved by the universal wheels at the lower end of the frame. The design of the universal wheels enables the device to flexibly turn and adapt to different construction sites;

[0024] The construction workers control the moving direction of the device through the handrail and move the device to the location of the old road surface that needs to be treated;

[0025] Step 2: Shoveling and cutting:

[0026] The scraping mechanism is installed at the front end of the frame and is used to remove the surface material of the old road surface; the second hydraulic cylinder drives the swing arm to move up and down, adjusting the height of the electric pick so that it can touch the road surface;

[0027] Once the motor is started, it drives the one-way screw to rotate, and the internal thread slide moves along the screw, thereby pushing the electric pick to perform the ground-shoveling operation and remove the damaged part of the old road surface;

[0028] Step 3: Cutting operation:

[0029] The cutting mechanism is installed on one side of the shoveling mechanism and is used to cut old road surfaces. The hydraulic cylinder drives the mounting plate up and down to adjust the height of the cutting disc mounting plate.

[0030] After the motor 2 is started, it drives the hexagonal slide bar and the transmission shaft to rotate through the transmission of the pulley 1 and the pulley 2, thereby driving the cutting disc on the cutting disc mounting disk to perform cutting operations;

[0031] At the same time, after the third motor is started, it drives the bidirectional screw to rotate, and the internal thread sleeve moves along the screw, pushing the semicircular push plate to slide in the concave groove, thereby adjusting the position of the cutting blade to achieve cutting of roads of different widths;

[0032] Step 4: Unloading and recycling:

[0033] The unloading mechanism is installed on one side of the cutting mechanism to collect and process the cut old road material; the hopper is fixed on the upper end of the frame, and the conveyor belt is installed at the bottom of the hopper to transport the cut material to the discharge port;

[0034] The hydraulic cylinder drives the baffle to open and close, controls the opening and closing of the discharge port, and discharges the cut material out of the device or recycles it to a designated location;

[0035] Step 5: Ramming and compaction:

[0036] The tamping mechanism is installed on the lower side of the discharge mechanism and is used to tamp and compact the treated road surface; the hydraulic cylinder drives the vibrating pressure plate up and down to adjust its contact position with the road surface;

[0037] After the motor 4 is started, it drives the eccentric block to rotate, generating vibration, and compacts the treated road surface through the vibrating pressure plate to ensure that the repaired road surface is flat and stable;

[0038] Step 6: Hydraulic and power systems:

[0039] The hydraulic pump box is fixed on the upper end of the frame, providing hydraulic power for the device to drive the extension and retraction of hydraulic cylinders 1, 2, 3 and 4;

[0040] Motor 1, Motor 2, Motor 3 and Motor 4 respectively provide power to drive the operations of shoveling, cutting, unloading and tamping.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. Efficient integrated design: The device integrates multiple functions such as shoveling, cutting, unloading, and tamping, and is carried and moved as a whole by the frame, avoiding the tedious process of operating multiple equipment separately in traditional construction, greatly improving construction efficiency and shortening construction period.

[0043] 2. Flexible unloading control: The unloading mechanism uses a hydraulic cylinder to drive a baffle to control the opening and closing of the discharge port. This allows for precise control of the timing and amount of material discharge, avoiding material waste and clutter in the construction area. Furthermore, the conveyor belt design allows for rapid and even delivery of materials to the designated location, ensuring continuity during the construction process.

[0044] 3. Precise Shoveling and Cutting Functions: The shoveling mechanism is driven by a hydraulic cylinder and motor, combined with a one-way lead screw and an internally threaded slide, enabling flexible extension and precise positioning of the electric pick, effectively adapting to the removal of road defects at varying depths and locations. The cutting mechanism, driven by a motor-driven pulley and featuring a bidirectional lead screw and a semicircular push plate, enables precise feeding and position adjustment of the cutting blade, ensuring smooth and accurate cutting to meet the requirements of cutting and repairing various road defects.

[0045] 4. Reliable ramming and compacting effect: The ramming mechanism adopts a combination of hydraulic cylinder and vibrating pressure plate. The motor drives the eccentric block to generate vibration, which can effectively tamp and compact the repaired road surface, improve the flatness and bearing capacity of the road surface, ensure the repair quality, and extend the service life of the road surface.

[0046] 5. Convenient Operation and Stability: The entire device is supported by universal wheels, allowing for flexible movement and adjustment of positions on the construction site. Furthermore, the movement of each mechanism is powered by a hydraulic pump box, ensuring stable and reliable power transmission. Operators can coordinate the various mechanisms through simple control devices, reducing operational difficulty and labor intensity while improving construction safety and reliability.

[0047] 6. Strong applicability: The device is suitable for treating a variety of road surface diseases. Whether it is local damage, cracks or large-scale potholes and other diseases, it can be effectively repaired through its multiple functional modules. It has wide applicability and practicality, can meet the needs of different construction scenarios, and provides an efficient and reliable solution for road maintenance and repair.
