Description

Simple and efficient rotary cutting device for street well

Technical Field

The utility model belongs to the technical field of town road ground well maintainer construction equipment, concretely relates to be applied to city street and carry out rotary-cut device to the ground well.

Background

Along with the rapid development of urban economy, urban construction steps are accelerated, urban traffic flow is increased suddenly and secondarily, and the road inspection well cover is subjected to the action of repeated impact of vehicles, so that the well cover is damaged and subsided, and the same-well road surface cracks, subsidence and other diseases can be caused frequently. The well frame of the common road inspection well is directly located on the inspection well built by bricks, the increase of traffic and the running of overweight vehicles lead to the fracture and collapse of mortar and bricks at the bottom of the well cover, and thus the well cover sinks on the road surface. The damage of the well periphery is common, the cast iron well cover frame is easy to vibrate, the well frame is arranged below the asphalt surface layer, and the asphalt on the well periphery is cracked due to severe vibration or settlement of the well frame. The urban road drainage system has the advantages that the facility function and the urban image are seriously influenced, the urban road drainage system is one of the strong municipal focus problems reflected by people, and the urban road drainage problem is also troubled.

In the road maintenance process, the saw blade form is mostly adopted for the repairing and cutting of the round well lid, and the saw blade cutting can only follow the limitation of straight line cutting and can not turn during cutting, so that only rectangular repairing pits can be formed during cutting, and most repairing modes are round hole square repairing modes. And when forming rectangle pothole, pothole edge is not the square type but the groined type, and the waste material clearance around to after the cutting has formed unnecessary cutting joints, can fill the restoration to the pothole in the repair process, but unnecessary cutting joints only simply fills pitch, leads to the peripheral structural strength of pothole to reduce, and the vehicle rolls the friction repeatedly, and because of factors influences such as expend with heat and contract with cold, can form new crack at the pothole periphery in different seasons, and then caused new road surface damage.

When the circumference of the road inspection well cover is cut, the traditional inspection well cover circumference cutting machine also adopts a saw blade cutting mode, for example, the road circumference inspection well cover cutting machine with the publication number of CN 108487031A, a rotating frame is fixedly connected on the outer wall of one side of a base through bolts, a driven gear is arranged inside the rotating frame, a rotating rod is welded at the central position of the bottom of the driven gear, a rotating rod seat is arranged at one end of the rotating rod, which is far away from the driven gear, a telescopic rod is welded on the outer wall of one side of the rotating rod seat, a disk is welded at one end, which is far away from the rotating rod seat, on the telescopic rod, the distance between the disk and the rotating rod seat can be adjusted according to the requirement, thereby the cutting radius is adjusted, a channel is erected through the distance between adjacent disks, the channel is drawn out from a groove, the cutting machine can move in the channel conveniently, the saw blade is continuously ground and bent in the cutting slit, so that the cutting life of the saw blade is short. And traditional inspection shaft lid circumference cutting machine is very inconvenient when carrying out the centre of a circle location, needs the manual work to squeeze into the location nail, still need take out the location nail after having cut, wastes time and energy. The utility model provides a circular well lid hole cutting machine of road for CN 110565495A, circular well lid hole cutting machine of road includes frame, mount pad and cutting device, wherein, the mount pad along from top to bottom to movable mounting in the frame, cutting device include along from top to bottom to the axis rotate install in the cutterhead subassembly of mount pad below, cutterhead subassembly include along the level to the blade disc that extends, the lower terminal surface of blade disc is equipped with a plurality of edges the blade that blade disc circumference interval set up, it is a plurality of the blade is followed but the radial position synchronization adjustment of blade disc, so that circular well lid hole cutting machine of road adapts to the well lid hole of the different diameter sizes of cutting shaping. When the technology is used for construction, each blade is in an inclined state in the downward drilling process, the cutting end face cannot be neatly cut, the stress of the cutter head is uneven, and the construction quality and the service life of equipment are affected.
