Auxiliary runway repairing device

Abstract

The invention relates to the field of plastic runways, and particularly relates to an auxiliary runway repairing device. The technical problem of the invention is to provide the auxiliary runway repairing device. According to the technical scheme, the auxiliary runway repairing device comprises a cutting mechanism, a chamfering mechanism, a sweeping mechanism bottom frame and the like; the cuttingmechanism is connected with the sweeping mechanism; and the chamfering mechanism is connected with the cleaning mechanism. When the device is used, a broken hole in the plastic runway is automatically cut into a circular block; the size of the cut part can be adjusted according to the size of the broken hole; and a slope with a width of 5 mm is automatically cut off along the edge of the cut part, a pit in the cut part of the plastic runway is automatically cleaned up, subsequent work is facilitated, only one person is needed for operation in the whole process, work efficiency is high, brokenholes in the plastic runway can be cut off in a short time, and repair work is facilitated.

Description

technical field [0001] The invention relates to the field of plastic runways, in particular to an auxiliary repair device for runways. Background technique [0002] The plastic track is also called the all-weather track and field track. It is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance, effectively improving sports performance and reducing the rate of falls. The plastic runway is composed of polyurethane rubber and other materials. It has certain elasticity and color, and has certain anti-ultraviolet ability and aging resistance. It is internationally recognized as the best all-weather outdoor sports floor material. [0003] In the prior art, after many years ...

Problems solved by technology

[0005] In order to overcome the existing technology, the plastic runway will be damaged after years of exposure to the sun and rain. People are prone to tripping when running on a runway full of small holes. Because it consumes too much resources to replace the entire runway, people use repairing. The method to solve it is to mark the damaged part, use a wallpaper knife to cut it evenly along the outer edge of the line, dig out an approximately circular pit, cut a 5 mm wide slope along the outer edge, and then clean it The bottom layer of sand, dry the foundation, and then repair it. The preparation process is cumbersome and inefficient. However, there are many small holes on the runway, and the workload of the workers is heavy. At the same time, they work outdoors, and the high temperature weather seriously affects the work process. The technical problem of the present invention: to provide a runway auxiliary repair device
