Efficient highway subgrade maintenance pavement crack pouring device

Abstract

The invention discloses an efficient highway subgrade maintenance pavement crack pouring device. An auxiliary cutting part of the efficient highway subgrade maintenance pavement crack pouring device sequentially comprises a hydraulic rod, a cylindrical gear, a vertical sliding rotating shaft, a bevel-gear-shaped driving gear and groove expanding assemblies from top to bottom in a rack, wherein thegroove expanding assemblies are arranged in a bilateral symmetry mode. The groove expanding assembly comprises a horizontal sliding rotating shaft, a cylindrical spring, a gasket, an auxiliary cutterand a bevel-gear-shaped driven gear, the bottom of a gear tooth gap of the driving gear is fixedly connected with rolling wheels installed on sliding rods, and all the sliding rods extend into the driving gear in a sliding fit mode and make smooth contact with the bottom end face of a sliding column capable of vertically sliding in the driving gear. The top end of the sliding column is connectedwith a compression spring, in the downward moving process of the driving gear, the rolling wheel makes extrusion contact with the top faces of gear teeth of the driven gear, and the length of the portion, capable of sliding into the driving gear, of the sliding rod needs to allow the driving gear and the driven gear to be kept in a standard meshing state. After crack pouring of pavement cracks isconducted, the crack pouring effect is good, and the durability is high.

Description

technical field [0001] The invention relates to the technical field of road engineering maintenance, in particular to an efficient road surface filling device for road subgrade maintenance. Background technique [0002] As an important infrastructure in the city, urban roads are the channels for citizens to travel and live. Under normal circumstances, when overhauling urban roads with severe road surface damage, measures to stop traffic must be taken, and the cycle is long, which aggravates urban congestion to a certain extent, affects the smooth flow of urban roads and the lives of citizens, and cracks in the road surface It is the most common form of road disease. When it rains, rainwater enters the roadbed along the cracks, causing further damage or collapse of the road, thus shortening the service life of the road. Studies have shown that cracks are mainly divided into two categories according to different causes: one is the structural damage cracks caused by the drivin...
