Description

Technical Field

[0001] This invention relates to the field of guiding devices, and more particularly to a resonant fracture trajectory guiding device and method. Background Technology

[0002] Cement concrete pavements possess advantages such as high strength, good stability, good durability, low maintenance costs, and suitability for nighttime driving, leading to their widespread application in early highway construction in my country. However, with my country's rapid economic development and the continuous increase in traffic volume and axle load, many early-constructed cement concrete pavements have suffered varying degrees of damage, significantly impacting their road performance. Therefore, researching and developing reliable, stable, durable, and inexpensive new technologies to retrofit old cement concrete pavements with asphalt overlays has become an urgent need for the industry.

[0003] The most advanced method currently available is full-section resonant crushing technology. It applies excitation force to old cement concrete pavements through the generation of special resonant waves, causing the old cement concrete slabs to break at their natural frequencies, creating novel mechanical structural layers with special scientific significance: a fracture layer and an interlocking layer. The fracture layer functions similarly to a damper, while the interlocking layer functions similarly to a spring oscillator. Full-section resonant crushing technology can completely eradicate reflective cracks, achieve rapid construction to reduce construction time impacts, and, more importantly, possesses the typical mechanical properties of long-life pavements, providing significant guidance for the design of future long-life pavements.

[0004] The most commonly used resonant crushing equipment is the resonant crusher. When in use, it needs to move forward along a fixed trajectory to crush the road surface. The existing trajectory guidance device is relatively bulky and inconvenient to transport, so it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a resonance fracture trajectory guiding device and method to solve the above-mentioned technical problems.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A resonant crushing trajectory guiding device includes several guide rails arranged side by side, with the guide rails on the same side connected end to end. Each guide rail has multiple threaded holes at both ends. A first connecting plate is provided between two adjacent guide rails, and the first connecting plate is connected to the threaded holes by multiple first screws. A sliding groove is provided on the guide rail along the length of the guide rail, and a slider is slidably connected in the sliding groove. The slider is connected to the resonant crusher through a connecting mechanism.

[0008] Preferably, the connecting mechanism includes a hydraulic lifting column, and a connecting cap is fitted on the top of the telescopic end of the hydraulic lifting column. The connecting cap is connected to the telescopic end through a connecting screw, and the connecting cap is fixedly connected to the resonant crusher.

[0009] Preferably, both ends of the slide are funnel-shaped.

[0010] Preferably, connecting cylinders are provided on the guide rails at the leftmost and rightmost ends, and a fixing rod is slidably inserted into the connecting cylinder.

[0011] Preferably, a second connecting plate is fixed on the connecting cylinder, and the second connecting plate is connected to the guide rail by a plurality of second screws.

[0012] Preferably, a limiting block is fixed to the top of the fixing rod.

[0013] Preferably, a spring is fitted onto the fixing rod, and the top of the spring is fixedly connected to the bottom of the connecting cylinder.

[0014] Preferably, the bottom end of the fixing rod is spike-shaped.

[0015] The beneficial effects of this invention are:

[0016] This invention designs an assembly-type guide device that can be easily and quickly assembled and disassembled. When needed, an appropriate number of guide rails can be transported to the destination and assembled. After use, the guide rails can be disassembled, packaged, and transported away, effectively solving the shortcomings of existing track guide devices that are bulky and inconvenient to transport.
