Cement concrete pavement grooving device for highway engineering

Abstract

The invention discloses a cement concrete pavement grooving device for highway engineering, and belongs to the technical field of equipment for highway construction. The cement concrete pavement grooving device for highway engineering comprises a fixed bottom plate, rotating seats are arranged at the lower ends of supporting legs, rolling wheels are arranged in the middle of the rotating seats, electric push rods are arranged on the left side and the right side of the fixed bottom plate correspondingly, universal wheels are arranged at the four corners of the bottom face of a base plate correspondingly, and a plurality of grooving blades are arranged in the middle of the outer wall of the circumference of a main shaft; a centering assembly is arranged on the front side of the middle of the bottom face of the fixed bottom plate, and a dedusting assembly is arranged on the rear side of the middle of the bottom face of the fixed bottom plate. Through cooperation of the rolling wheels arranged in the middle of the rotating seats, the electric push rods on the two sides of the middle of the fixed bottom plate and the universal wheels at the four corners of the bottom face of the base plate, workers can put down and put away the universal wheels conveniently according to actual requirements, and thus the workers can conduct transverse groove carving treatment on the road surface conveniently and rapidly, the device can be quickly moved, the grooving difficulty is greatly reduced and the grooving efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of equipment for road construction, and more specifically, relates to a cement concrete pavement carving device for road engineering. Background technique [0002] In the process of cement concrete pavement construction, in order to ensure that the pavement is skid-resistant, it is necessary to use the groove process to increase the friction coefficient of the pavement to ensure the safety of vehicles. Commonly used grooves are horizontal grooves and vertical grooves. The trend of the transverse groove is perpendicular to the driving direction, and the longitudinal groove is parallel to the driving direction. Because the coefficient of friction of transverse grooves is higher than that of longitudinal grooves, horizontal grooves are more widely used in the construction of ordinary roads. In order to quickly and high-quality complete the work of pavement lateral groove. Relevant staff often use the cement ...

AI Technical Summary

Problems solved by technology

Although the above-mentioned device can realize the engraving of road grooves, there are still the following problems: In order to make the traffic in rural areas more convenient, a large number of rural roads have been built in my country. Due to the narrow surface of the rural roads and poor load-bearing capacity, when related construction When units need these township roads to carry out grooving operations, large-scale construction equipment is difficult to use

However, the first type of device lacks measures to control the moving direction of the device, which requires extremely high technical level of the operator. A little carelessness will cause the road surface to be skewed and affect the effect of road surface grooves. Although the second type of device You can control the use angle of the universal wheels, but you need to adjust the four universal wheels every time, which is inconvenient to use

Both devices are too inefficient for notching work

In addition, in the existing grooving device, multiple rollers are usually set at the bottom of the device to achieve grooving during movement, and a depth display scale is provided, but according to the width of the grooving, the narrower trough is smaller than the gap between the two wheels. so that at least four wheels are stably supported at the same time to make the depth of the groove uniform, and the width of the wider groove may be greater than the distance between the two wheels during the engraving process, so that the groove in the groove device If one side is inclined, especially when using the artificial handrail to press the pushing device, it is easy to cause the depth of the groove cutter body to go deep into the ground to change, so that the depth of the groove body is different
