Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, and more specifically, to a municipal road cutting device. Background Art

[0002] In the process of municipal road maintenance and reconstruction, pavement cutting is an important preparatory work. During the coagulation and hardening process of concrete pavement, cement hydration will release a lot of heat, causing the concrete temperature to rise. Then the concrete temperature begins to drop. During the cooling process, the concrete has already coagulated and hardened. The shrinkage caused by the cooling will cause the concrete to crack. The direction of these cracks is relatively random, which seriously affects the quality and service life of the pavement. Therefore, generally after the concrete is poured, the contraction joints should be cut. The cutting depth is about one-third of the thickness of the road slab. This can induce concrete shrinkage cracks to occur along the cut joints and prevent random cracks. The pavement cutting machine is mainly used for cutting the pavement. It can cut expansion joints on the paved pavement through the high-speed rotating blade. It is widely used in the paving of cement roads and asphalt roads.

[0003] The existing equipment is not easy to control the cutting depth during normal use, which makes it inconvenient for the staff to use it normally. At the same time, the existing device lacks dust reduction function, which causes a lot of dust to be generated when people cut the road surface with the device, causing damage to the environment. To solve the above problems, we have launched the following device Utility Model Content

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides a municipal road cutting device, including a base, a support frame and a through hole, the support frame is fixedly connected to the upper surface of the base, an adjusting mechanism is arranged inside the support frame, a cutting mechanism is arranged and connected to the lower surface of the adjusting mechanism, the adjusting mechanism includes a bearing, the bearing is passed through the surface of the support frame, a rotating shaft is passed through the bearing, a knob is fixedly connected to the upper end of the rotating shaft, a threaded column is fixedly connected to the lower end of the rotating shaft, a threaded tube is threadedly connected to the lower end of the threaded column, a movable frame is fixedly connected to the lower end of the threaded tube, a cutting mechanism is arranged inside the movable frame, a through hole is opened on the surface of the base, the position of the through hole corresponds to the position of the cutting mechanism, a fixing platform is fixedly connected to the upper surface of the base, a nozzle is fixedly connected to the upper surface of the fixing platform, and the position of the nozzle corresponds to the position of the through hole.
