Asphalt concrete pavement longitudinal joint cutting equipment

Abstract

The invention relates to asphalt concrete pavement longitudinal joint cutting equipment. The equipment comprises baseboards, travelling wheels, assisting travelling devices, an installation rack and acutting device, wherein the number of the baseboards is two, the travelling wheels are installed at the lower ends of the baseboards, the assisting travelling devices are installed at the upper endsof the baseboards, the upper ends of the assisting travelling devices are connected with the installation rack, the cutting device is installed at the lower end of the installation rack, the assistingtravelling devices comprise power mechanisms and assisting travelling mechanisms, and the cutting device comprises a position adjusting mechanism and a cutting mechanism. By means of the equipment, the problems can be solved that in an existing curve longitudinal contraction joint cutting process, the working stability is poor, the cutting effect is not ideal, and potential safety hazards exist;the function of automation longitudinal joint cutting of an arc road can be achieved, and the equipment has the advantages that the working stability is good, the cutting effect is good, the safety ishigh and the like.

Description

technical field [0001] The invention relates to the field of asphalt concrete pavement processing equipment, in particular to a longitudinal seam cutting equipment for asphalt concrete pavement. Background technique [0002] Concrete is mainly divided into asphalt concrete and cement concrete. At present, asphalt concrete is the most widely used. The upper layer of asphalt concrete pavement is composed of concrete panels with a certain thickness, which has the property of thermal expansion and contraction. Due to changes in temperature throughout the year, concrete will expand and contract to varying degrees. And within a day and night, when the daytime temperature rises, the temperature of the top surface of the concrete slab is higher than that of the bottom surface, and this temperature gradient will cause the middle part of the slab to protrude. When the temperature drops at night, the temperature of the top surface of the concrete slab is lower than that of the bottom ...
