Description

Technical Field

[0001] This invention relates to the field of highway engineering technology, specifically to a pavement crack treatment device for highway engineering. Background Technology

[0002] Many surface defects in cement pavements, if not repaired promptly, can quickly develop into incurable problems. Currently, there are no ideal solutions for these defects; the common approach is to wait until the damage has progressed to a certain extent before patching, leading to a significant waste of valuable materials. Furthermore, the cost of prolonged road closures is increasingly being recognized. Developing materials and technologies that can promptly repair these surface defects would be a significant contribution to the maintenance of cement concrete roads in my country and to reducing material waste. In recent years, some enterprises and road maintenance organizations have conducted extensive research and exploration, discovering some effective solutions and materials.

[0003] When repairing a road surface, it is necessary to remove impurities from the cracks and then fill them with concrete. During the filling process, it is necessary to maintain the relative balance between the device and the road surface. While road crack repair devices on the market are efficient when repairing smooth roads, they often cannot maintain balance when repairing roads with large potholes and cracks. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a road surface crack treatment device for highway engineering, comprising a shell, a leveling device provided in the inner cavity of the shell, a first support frame fixedly connected to the upper surface of the shell, a mixing device provided at the end of the first support frame away from the shell, a slide rail fixedly connected to the side surface of the shell, and a pouring device provided between the opposite surfaces of the slide rail.

[0005] Preferably, the leveling device includes a panel, a limiting base fixedly connected to the upper surface of the panel, a limiting block fixedly connected to the inner wall of the outer shell, the limiting block being fitted into the slot of the limiting base, a limiting strip fixedly connected to the upper surface of the panel, and a slot hole formed on the upper surface of the panel. The leveling device includes a left fixing plate, an alignment post fixedly connected to the lower surface of the left fixing plate, the alignment post being fitted into the slot hole formed on the upper surface of the panel, and an elastic plate fixedly connected to the lower surface of the left fixing plate. The elastic plate is pressed and adapted to the lower surface of the panel. By setting the leveling device, the road crack treatment device can remain stable even on uneven road surfaces, thereby ensuring stability and accuracy when treating road cracks. By setting the limiting block and the limiting base, the outer shell can be fixed to the upper surface of the panel, thereby preventing dust and mud from contaminating the leveling device during crack treatment. The setting of the elastic plate and the alignment post allows the left fixing plate to be tightly fixed to the panel.

[0006] Preferably, an arc-shaped plate is fixedly connected to the upper surface of the left fixed plate, the arc-shaped plate is sleeved on the outer surface of the limiting strip, a right fixed plate is fixedly connected to the end of the arc-shaped plate away from the left fixed plate, a balancing device is provided at the end of the right fixed plate away from the arc-shaped plate, and a limiting plate is fixedly connected to the left outer surface of the balancing device. By setting the right fixed plate and the arc-shaped plate, the left fixed plate and the right fixed plate are kept on the same plane, and the limiting plate is pressed and adapted to the lower surface of the panel, so that the left fixed plate and the right fixed plate are always tightly combined with the panel during the support process.

By setting a balancing device, the panel can remain stable even on uneven road surfaces, thus enabling the road crack repair work to proceed smoothly. During operation, the device is placed on the road surface to be repaired. Due to the uneven road surface, the support legs are in contact with the ground under the action of gravity. Under the action of the rack column on the outer surface of the arc-shaped spring, the outer surface of the support leg engages with the rack column, thereby keeping the support leg fixed and achieving the effect of stabilizing the device.

[0008] Preferably, the stirring device includes a second support plate fixedly connected between opposite surfaces of the slide rails. The stirring device also includes a feed hopper fixedly connected between opposite surfaces of a first support frame.

During operation, the operator pours the repair material into the material box, then connects the rotating motor to the power supply and turns on the rotating motor switch. The rotating motor starts to work, driving the rotating column and stirring blade to rotate, thereby achieving the stirring effect of the material. After stirring, the material flows into the casting device through the discharge pipe.

[0009] Preferably, the stirring plate includes a fourth support plate, which is fixedly connected to the outer surface of the rotating column. A first support block is fixedly connected to the upper surface of the fourth support plate, and a striking block is fixedly connected to the end of the fourth support plate away from the rotating column.

[0012] I. The road surface crack treatment device used in this highway project, by setting a leveling device, can maintain stability on uneven road surfaces, thus ensuring stability and accuracy in treating road surface cracks. By setting a limiting block and a limiting base, the outer shell can be fixed to the upper surface of the panel, thereby preventing dust and mud from contaminating the leveling device during crack treatment. The setting of elastic plate and alignment column allows the left fixing plate to be tightly fixed to the panel.

[0013] II. The road surface crack treatment device used in this highway project, by setting up a balancing device, can keep the panel stable even on potholed road surfaces, thus enabling the road surface crack repair work to proceed smoothly. During operation, the device is placed on the road surface to be repaired. Due to the potholes, the support legs are in contact with the ground under the action of gravity. Under the action of the rack column on the outer surface of the arc-shaped spring, the outer surface of the support leg meshes with the rack column, thereby keeping the support leg fixed and achieving the effect of stabilizing the device.

[0014] III. The road surface crack treatment device used in this highway project, by setting up a mixing device, can mix the repair material, thereby increasing the firmness of the repair. During operation, the operator pours the repair material into the material box, then connects the rotating motor to the power supply and turns on the rotating motor switch. The rotating motor starts working, driving the rotating column and mixing blade to rotate, thereby achieving the mixing effect of the material. After the material is mixed, it flows into the pouring device through the discharge pipe. The setting of the impact block, the first elastic strip and the second elastic strip can deeply mix the material, making the substances in the material that are difficult to mix more evenly. The setting of the scraper can scrape the material on the outer surface of the material box.

[0015] IV. The road surface crack treatment device used in this highway project can pour the mixed material by setting up a pouring device. After mixing, the material enters the telescopic hose and the guide pipe through the discharge pipe. The circular plate acts as a diversion device to prevent the material from piling up. Under the action of the guide plate, the mixed material can flow evenly into the crack. Attached Figure Description
