Combined cutting tool type airport pavement joint cleaning machine

Abstract

The invention relates to a combined cutter type airport pavement crack cleaning machine; the complete machine essentially consists of a power device comprising an engine, a gear box, a chassis, a driving wheel and a clutch and brake operation mechanism, a crack cleaning device and a guiding device which are electrically controlled, and a pull-type seat. The crack cleaning device essentially consists of a cutter lifting mechanism, a combined cutter and a cutter folding mechanism; the guiding device essentially consists of a guide wheel, a guide wheel support rod and an electrical guiding lifting pushing rod. The machine has no dust pollution, does not damage the airport pavement and can meet the high requirements of the airports to environment protection; the designed crack cleaning device is a high-strength shear type floating cutter, can realize electrical lifting, is applicable to joints with different width, can flexibly control the depth of the crack needed to be cleaned, and can quickly clean embedded materials and impurities which lose effect in the joints of the airports with high quality. The machine has compact integral structure, is flexible and convenient to be operated and moved, and is an ideal device for repairing the joints of the airport and concrete pavement.

Description

technical field [0001] The invention relates to a road seam cleaning machine, in particular to a combined cutter type airport road seam cleaning machine. Background technique [0002] When concrete pavements are laid, joints are left. Over time, the original caulking material will gradually age, which will not only accelerate the damage of the road surface at the joint, but also cause safety hazards to the operation of the vehicle. Especially for airport runways, which are crucial to flight safety, the invalid objects in the joints must be cleaned up in time, and new materials must be re-embedded to fully bond the joint walls. Existing all kinds of pavement seam cleaning machines, some are bulky and bulky, inconvenient to operate, some are not ideal in cleaning speed and effect, some are dusty when cleaning seams, and the environment is seriously polluted, thus restricting these seam cleaning machines Promotion and application in certain occasions. For example, most of th...

AI Technical Summary

Problems solved by technology

The workload of manual seam cleaning is heavy and the construction period is long, so that the internal work of the airport and the navigation of the aircraft will be affected to a certain extent; and the quality of manual seam cleaning is difficult to guarantee, which directly affects the effect of refilling in the subsequent process
