Asphalt auxiliary pouring equipment for municipal road cracks

Abstract

The invention relates to an auxiliary pouring equipment for cracked asphalt on municipal roads, which includes a machine frame, traveling wheels, a pouring device and a material storage box. Mechanism and No. 2 driving mechanism, the material storage box includes box body, electric heating pipe, feeding pipe, lifting plate, lifting cylinder, rotating mechanism, stirring shaft, stirring frame, sliding block, connecting frame, threaded rod and fixed cylinder. The invention provides a kind of asphalt auxiliary pouring equipment for municipal road cracks, which uses a multi-point filling method to fill road cracks. During the pouring process, the storage box can evenly stir the molten asphalt inside to ensure the temperature of the molten asphalt everywhere. Consistent, the infiltration speed of molten asphalt is accelerated by pressurization after pouring, so that the molten asphalt can be closely combined with deep cracks to achieve the purpose of improving the filling strength.

Description

technical field [0001] The invention relates to the technical field of municipal roads, in particular to an auxiliary asphalt pouring equipment for municipal road cracks. Background technique [0002] Regardless of whether it is cement or asphalt pavement, various damages, deformations and other defects will appear one after another after being opened to traffic for a period of time. Crack is one of the most common, most prone and earliest diseases among all kinds of damages on the pavement. It accompanies the whole service life of the road and aggravates with the growth of road age. [0003] After cracks appear on the pavement, they should be sealed and repaired in time, otherwise rainwater and other debris will enter the surface structure and subgrade along the cracks, resulting in a decrease in the bearing capacity of the pavement, accelerating partial or piece-by-piece damage to the pavement, and shortening the service life of the pavement. [0004] When there are crack...

AI Technical Summary

Problems solved by technology

[0005] (1) The existing filling equipment uses more than one nozzle to inject molten asphalt into road cracks. The diameter of the nozzle is small, so it can only fill a small section of cracks each time, and the filling efficiency is low. Its position is controlled to carry out filling operations along the crack trend. Due to the poor accuracy of manual operation, the deviation between the nozzle movement route and the actual crack trend is large, and it often consumes more asphalt than the actual demand to ensure Everywhere the cracks are filled;

[0006] (2) The existing filling equipment is provided with storage containers to store, heat and keep warm the molten asphalt, but after the asphalt enters these storage containers, the position remains basically unchanged, so there will be differences with those set in the storage containers. The temperature of the asphalt near the heating element is high, and the temperature of the asphalt far away from the heating element is low, the asphalt is heated unevenly, which directly affects the subsequent pouring effect
