Rapid joint cutting device for traffic road pavement

Abstract

The invention discloses a traffic road pavement rapid joint cutting device, and relates to the technical field of road construction equipment, the traffic road pavement rapid joint cutting device comprises a moving shell, the inner wall of the moving shell is fixedly connected with a partition plate, the surface of the partition plate is slidably connected with a first moving inner shell, and the inner wall of the first moving inner shell is fixedly connected with a fixing shaft; a first motor is fixedly installed on the inner wall of the movable shell, a double-groove belt wheel is fixedly connected to the surface of an output shaft of the first motor, a first belt wheel is fixedly installed on the surface of the cutting disc, and the first belt wheel is in transmission fit with the double-groove belt wheel through a belt. Through mutual cooperation of the structures, the road surface joint cutting device has the effects that the automation degree is high, the road surface joint cutting efficiency is greatly improved, the joint cutting depth can be accurately controlled, and cut expansion joints are automatically cleaned.

Description

technical field [0001] The invention relates to the technical field of road construction equipment, in particular to a rapid road surface cutting device for traffic. Background technique [0002] The joints cut on the concrete pavement are called expansion joints. During the setting and hardening process of the concrete, the temperature of the concrete begins to drop. During the cooling process, the concrete has already set and hardened. The shrinkage caused by the cooling will cause the concrete to crack, and the direction of the cracks is relatively random, which seriously affects the quality of the road surface and service life, therefore, expansion joints are generally cut after concrete placement to prevent random cracks from appearing. [0003] The traditional cutting of expansion joints is generally carried out by manual hand-held tools, which not only has certain safety risks and high labor intensity, but also cannot accurately control the cutting depth of expansion ...
