Problems solved by technology

[0003] Because the concrete pavement to be cut contains a large number of irregularly arranged stones, it is difficult to cut, and the cut seam after cutting is seriously damaged, which affects the connection between the asphalt concrete filling and the cutting edge; the current common cutting method is to use a road cutting machine. This type of cutting machine will cause rockfall when cutting asphalt concrete pavement, which will seriously damage the cutting seam and cause serious pollution; there is also a kind of equipment that uses rolling to cut the road surface, but it is relatively heavy and difficult to use flexibly; The waste that needs to be removed after cutting is usually in one piece, making cleaning inconvenient

Embodiment 1

[0032] see Figure 1-5, a kind of municipal road damaged asphalt pavement cutting and cleaning equipment, comprising a cutting positioning seat 1 and a circular punching and rolling cutting device 2 arranged at the lower part of the cutting positioning seat 1, the cutting positioning seat 1 is used to control the rotation and rotation of the circulating punching and rolling cutting device 2 Linear movement, the function of the cutting positioning seat 1 is to fix the upper part of the damaged road surface, on which four legs with bottom nails can be set, the legs support the ground, and the upper part of the cutting positioning seat 1 can be equipped with common gear-driven Rotary disk, the bottom of the rotary disk is fixed with a rotating frame 11, and the rotating frame 11 is linearly slidably matched with the circulating punching and rolling cutting device 2; the circulating punching and rolling cutting device 2 includes a horizontally distributed rectangular bearing plate ...

Embodiment 2

[0034] see figure 2 , and the difference from Embodiment 1 is that the counterweight body 25 is fixedly arranged on the top of the bearing vertical plate 232. The counterweight body 25 is a box structure, and one side thereof is screwed with a water inlet pipe 251 and a drain pipe 252. The gap in the counterweight body 25 is With the floating plate 3, the counterweight body 25 can be made into a water tank, and the size of the inertial impact force can be increased by installing and draining water, which has the ability to adjust the cutting force, and can discharge water when not in use, reducing the transfer weight and facilitating transfer; The floating plate 3 is used to reduce the shaking range of the water body in the water tank, and has high safety.

Embodiment 3

[0036] see Figure 6 , and the difference from Embodiment 1 is that the suspension tube 22 is rotatably connected with a positioning tube 221, and the outer wall of the positioning tube 221 is fixedly provided with a row of punches 2211. Since the suspension tube 22 is distributed obliquely, the arrangement direction of this row of punches 2211 Arrange along the axial direction of the suspension tube 22, and gradually lengthen along the direction away from the hob cutter 27; after cutting the ground, the positioning tube 221 can be rotated to ensure that a row of punches 2211 are in contact with the ground part downwards. In the example 1, the circular punching function can break the damaged road surface and fragment the damaged road surface for easy cleaning; the positioning pipe 221 is provided with a locking member 4, which is a bolt used in conjunction with the suspension pipe 22, The positioning pipe 221 is fixed by using a common structure of bolt rotation and shrinkage,...

Abstract

The invention discloses municipal road damaged asphalt pavement cutting and cleaning equipment. The equipment comprises a cutting positioning seat and a circulating punching and rolling cutting devicearranged at the lower part of the cutting positioning seat, and the cutting positioning seat is used for controlling the rotating and linear motion of the circulating punching and rolling cutting device. According to the municipal road damaged asphalt pavement cutting and cleaning equipment, the circulating punching and rolling cutting device is mounted, and comprises a rectangular bearing plate,a suspension pipe, a circular punching combination, a cam, a balance weight body, a connecting rod and a hobbing cutter which are horizontally distributed, the suspension pipe is distributed in an inclined manner, the hobbing cutter is rotatably connected to the free end of the suspension pipe, the circular punching combination can apply inertia counter-acting force of the balance weight body tothe hobbing cutter and then is matched with the hobbing cutter to roll the road surface to achieve the effect of cutting the road surface, and the equipment is small in size, convenient to operate, high in flexibility, high in cutting safety and free of pollution.

Description

technical field [0001] The invention relates to the technical field of municipal road construction, in particular to a cutting and cleaning device for damaged asphalt pavement of municipal roads. Background technique [0002] Asphalt pavement is various types of pavement formed by paving and rolling asphalt concrete. After a period of use, asphalt pavement will crack and break, and the unevenness of unevenness will occur. Therefore, it needs to be repaired. The current repair method is partial The damaged pavement is cut in a closed loop, and the pavement after cutting is in the sinkhole state, and then new asphalt concrete is filled in the sinkhole, and finally rolled and flattened. [0003] Because the concrete pavement to be cut contains a large number of irregularly arranged stones, it is difficult to cut, and the cut seam after cutting is seriously damaged, which affects the connection between the asphalt concrete filling and the cutting edge; the current common cutting...
