Concrete pavement cutter travel mechanism

Abstract

The invention belongs to the technical field of concrete processing machinery, and particularly relates to a concrete pavement cutter travel mechanism. The concrete pavement cutter travel mechanism comprises a cutter body, wherein a roller is arranged below the machine body, the axis of the roller is connected with a rotating shaft through a flat key, the upper side of a stander is hinged to a crankshaft, the lower end of the crankshaft is hinged with a connecting rod in a suspension manner, the lower end of the connecting rod is hinged to the rotating shaft, the lower end of the crankshaft is also hinged with an air cylinder piston rod, and the air cylinder piston rod is obliquely arranged on the right side of the crankshaft; the machine body on the right lower side of the crankshaft is hinged with a swinging rod, and the free end of the swinging rod is hinged to the middle part of the connecting rod. By adopting the concrete pavement cutter travel mechanism, the roller can be automatically folded and unfolded and can be prevented from being damaged.

Description

technical field [0001] The invention belongs to the technical field of concrete processing machinery. Background technique [0002] "Concrete cutting" refers to the construction technology of cutting concrete components, walls, roads, etc. by using tools such as hydraulic wall saws, electric disc saws, water drills or road cutters. It has strong cutting ability, no static damage, and high efficiency. High, water cooling, no construction dust and other characteristics. The joints cut into concrete pavements are called 'condensation joints'. During the setting and hardening process of concrete, the hydration of cement releases a large amount of heat, which causes the temperature of concrete to rise; most of the hydration reaction of cement ends, and the temperature of concrete begins to drop. During the cooling process, the concrete has solidified and hardened, and the shrinkage caused by the cooling will cause the concrete to crack, and the direction of the cracks is relati...

AI Technical Summary

Problems solved by technology

[0003] The existing concrete pavement cutting machines all use rollers to move to the place to be cut. The rollers are hinged to the cutting machine, and manual operation is required when using and retracting. If the gravity of the cutting machine moves, the rollers will bounce back to the stacking position, causing the rollers to be impacted during this process and causing damage. Moreover, because the cutting machine is very heavy, it will take more physical strength to manually turn the rollers
