A road crack filling machine

Abstract

The invention discloses a crack filling machine for roads. There are heat-resistant silicone skirts on the side and right sides, heat-resistant silicone sheets arranged horizontally on the bottom of the cover plate, an injection port through the cover plate is provided on the top surface of the cover plate, and micro The micro switch is equipped with a vertically downward driving rod, and the top of the cover plate is equipped with a joint filling device. The joint filling device includes a tank body arranged vertically, and the relative position of the side wall of the tank body is set. There is a handle for easy moving of the tank and an injection port that can be opened and closed. There is a crack repair agent inside the tank body, a piston is installed on the top of the crack repair agent, and an electric push rod is installed on the top of the piston to control the automatic lifting of the piston. The beneficial effects of the invention are: not only higher repair efficiency but also more environmental protection.

Description

technical field [0001] The invention belongs to the technical field of road repair, and in particular relates to a road crack filling machine. Background technique [0002] Asphalt pavement is one of the main structural forms of highways, bridges, and urban roads. Under the action of various factors, functional defects such as cracks, edge collapse, and misalignment often appear on the pavement. In order to ensure the smooth flow of the road, road cracks need to be repaired Repairing, at present the main repairing method mostly adopts injecting corresponding crack repairing agent into the crack. [0003] The liquid crack repair agent is injected into the crack and finally solidifies to achieve the purpose of strengthening the foundation, filling the void or lifting the floor. In order to inject the crack repair agent conveniently, a corresponding crack repair agent filling machine is required. Most of the current joint filling machines use trolleys Structure, the bottom of ...

AI Technical Summary

Problems solved by technology

[0004] First of all, the cracks on the road are narrow and tortuous, and the structure of the trolley is large, so it cannot be conveniently turned with the cracks. The crack repair agent sprayed out by the nozzle is often sprayed on the road surface, and cannot be sprayed into the cracks, which not only affects the construction efficiency, but also requires follow-up Cleaning is very troublesome. Then, the main structure of the crack repair agent is asphalt. Asphalt has a large odor and is toxic to a certain extent if it is inhaled for a long time. Most of the traditional joint filling machines will expose the crack repair agent to the air during the filling process. In the process, it will cause air pollution and even affect the personal safety of the construction workers. Then, after the crack filling agent is poured into the cracks, the traffic cannot be resumed until the crack repairing agent is completely solidified. If it is a traffic artery, the time required for the crack repairing agent to solidify will cause Huge property loss. Finally, the traditional joint filling machine requires construction personnel to keep an eye on the injection volume of the crack repair agent, and judge whether the crack is completely filled and whether there is bubbles based on experience. The whole repair process is time-consuming and laborious
