Description

Technical Field

[0001] This invention relates to the field of compaction machinery technology, and more specifically to a compaction device and its operating method with edge compaction function. Background Technology

[0002] With the continuous expansion of my country's high-speed railway construction scale, the number of high-speed railway transition sections is increasing. The transition section is a section that requires special treatment when the roadbed connects with structures, and it is the key to controlling uneven settlement of the roadbed.

[0003] However, the number of defects in the transition section is also increasing year by year. Traditional small compaction equipment has its vibration damping devices set on both sides, which makes it impossible to achieve edge compaction. The effective compaction range is about 10cm away from the structure. Within this 10cm range, manual compaction is still required. However, it is not easy to control the compaction degree when manually compacting the edge of the transition section. Water seepage and settlement problems often occur in the edge section, which can easily damage the structure and waterproof layer. Furthermore, when the existing compaction equipment is compacting the edge section, it is easy to cause collisions, which can damage the compaction equipment and the transition section.

[0004] Therefore, how to provide a compaction device and operation method with edge compaction function that optimizes vibration reduction, solves the problem of non-edge compaction, improves the construction quality of transition sections, and avoids collisions is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a compaction device and operating method with edge compaction function, which aims to solve one of the problems in the above-mentioned background technology, optimize the vibration reduction to solve the problem of edge compaction, improve the construction quality of the transition section and avoid collisions.

[0006] To achieve the above objectives, in one respect, the present invention provides a compaction device with edge-fitting compaction function, comprising:

[0007] The frame includes a horizontal support, a vertical support, and a semi-circular support. The top of the vertical support is connected to the vehicle body. The horizontal support is connected to the right end of the vertical support. The semi-circular support is connected to the left end of both the horizontal support and the vertical support. A drive assembly is provided on the horizontal support. A shock absorber is provided between the drive assembly and the horizontal support. The inner ring of the semi-circular support has a groove.

[0008] A steel wheel, the right end of which is connected to the drive assembly, and the left end of which is rotatably mounted in the semi-circular bracket, the left end of which extends out of the semi-circular bracket and beyond the left end of the vehicle body;

[0009] A shock-absorbing assembly is disposed within the groove and contacts the steel wheel;

[0010] The compaction detection device includes an image acquisition camera, an image data processor, and a route trajectory prediction display. Multiple image acquisition cameras are installed on the exterior of the vehicle body. Each image acquisition camera is connected to the image data processor via a signal. The image data processor is connected to the route trajectory prediction display via a signal. The route trajectory prediction display is located at an observable position on the exterior of the vehicle body.

[0011] Furthermore, the shock-absorbing assembly includes a roller and two shock-absorbing layers. One shock-absorbing layer is disposed at the bottom of the groove, and the other shock-absorbing layer is disposed at the opening end of the groove and in contact with the steel wheel. The roller is disposed between the two shock-absorbing layers.

[0012] Furthermore, the drive assembly includes a drive motor, a transmission shaft, and eccentric wheels. The drive motor is located at the end of the shock absorber away from the horizontal support. The transmission shaft is fixedly connected to the output end of the drive motor. The end of the transmission shaft away from the drive motor extends into the interior of the steel wheel. Multiple eccentric wheels are provided, and all of the multiple eccentric wheels are fixedly mounted on the transmission shaft.

[0013] Furthermore, the horizontal support is U-shaped, the vertical support is L-shaped, and the steel wheel can rotate within the horizontal and vertical supports.

[0014] Furthermore, it also includes a scraper, which is hinged to one end of the horizontal support, and the scraper is used to clean the outer surface of the steel wheel.

[0015] Furthermore, it also includes a collision warning device, which is installed on the vehicle body and is connected to the route trajectory prediction display via a signal. The collision warning device provides early warning to avoid collisions with structures in the transition section.

[0016] On the other hand, the present invention also provides an edge-fitting compaction operation method, using the above-described compaction equipment with edge-fitting compaction function, including the following steps:

[0017] Step 1: Identify the transition section that needs to be compacted;

[0018] Step 2: The left end of the steel wheel is used to press and compact the transition section, with a maximum distance of 3cm between the steel wheel and the structure.

[0019] Step 3: The shock absorber dampens the right end of the steel wheel, and the shock absorption assembly dampens the left end of the steel wheel.

[0020] Step four: The image acquisition camera collects information from various locations on the vehicle body and sends the collected information to the image data processor for processing. The route trajectory prediction display analyzes the processed data and predicts the vehicle's trajectory. In conjunction with the collision warning device, it provides early warning to avoid collisions between the vehicle body and the structure in the transition section during the compression process.

[0021] Step 5: The scraper cleans the outer surface of the steel wheel.

[0022] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a compaction device with edge compaction function. By setting the left end of the steel wheel to extend out of the semi-circular bracket and beyond the left end of the vehicle body, the shock absorber and shock absorption component dampen the left and right ends of the steel wheel. Without the influence of the frame and shock absorber of traditional compaction equipment, it can compact the transition section edge by edge, solving the problem of not being able to compact edge. By setting a compaction detection device, it can avoid the compaction device from colliding with the structure of the transition section. Attached Figure Description

[0033] The steel wheel 6 has its right end connected to the drive assembly 3, and its left end rotatably mounted in the semi-circular bracket 23. The left end of the steel wheel 6 extends out of the semi-circular bracket 23 and beyond the left end of the vehicle body 1. The left end of the steel wheel 6 is not affected by the traditional compaction equipment frame 2 and shock absorber 4, and can perform edge compaction on the transition section, achieving a maximum distance of 3cm between the small compaction equipment and the structure, thus solving the problem of edge compaction.
