Description

Technical Field

[0001] The invention relates to a road surface repairing and cleaning device, belonging to the technical field of road surface maintenance. Background Art

[0002] With the rapid development of the transportation industry, asphalt pavement, as one of the main forms of roads, bears a heavy traffic load. However, due to the influence of various factors, such as climate, traffic flow, construction quality, etc., asphalt pavement will inevitably suffer various damages during use, among which potholes are one of the most common forms of damage. Potholes not only affect the aesthetics of the road, but more importantly, they pose a threat to driving safety, so they need to be repaired in a timely manner.

[0003] When repairing existing potholes, it is necessary to use a road cutting machine to cut the edges of the potholes. After cutting, the excess asphalt pavement inside the potholes is removed. After removal, the inside of the potholes is blown clean with high-pressure air, and finally the cold patch material is laid into the potholes and compacted.

[0004] The inventors have discovered that the prior art has at least the following technical problems:

[0005] The edges of potholes are usually irregular in shape. After being cut by a road cutting machine, a large part of the asphalt pavement inside the saw seam (pothole edge) needs to be removed. When the pothole is too large, more edges need to be removed. When construction workers use electric picks to remove them, they need to work for a long time, which greatly increases the labor intensity. When all the pieces are broken, they are collected on the truck with a shovel. The construction efficiency is very low, which affects the subsequent traffic. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, provide a road surface repair and cleaning device, reduce the operating intensity of construction workers, and improve work efficiency.

[0046] A weighing box 321 is provided at the upper end of the collecting box 32 for placing counterweights and tools.

[0047] A positioning assembly 5 is installed at the front end of the chassis 33 corresponding to the swing frame 13 , and the positioning assembly 5 is used to support and fix the swing frame 13 .

[0048] The positioning assembly 5 includes a positioning seat 51, a support rod 53 and an electric cylinder 52. The positioning seat 51 is installed on the front end of the chassis 33, the support rod 53 is hinged to the front end of the positioning seat 51, the fixed end of the electric cylinder 52 is hinged to the rear end of the positioning seat 51, and the telescopic end of the electric cylinder 52 is hinged to the support rod 53. When the electric cylinder 52 is actuated, the support rod 53 is lifted up, and the upper end of the support rod 53 supports the swing frame 13, thereby positioning the swing frame 13 to the upper end, thereby avoiding interference between the impact assembly 11 and the ground when the equipment is simply moved. During construction, the telescopic end of the electric cylinder 52 can be retracted.

[0049] The impact assembly 11 includes an impact column 111 installed at the front end of the swing frame 13 , and a plurality of impact claws 112 are installed on one side of the impact column 111 .

[0050] The cross section of the impact column 111 is square, and the impact claws 112 are installed on one of the surfaces. The impact claws 112 are installed on the impact column 111 in a row, which ensures the working efficiency.

[0051] An arc groove 131 is provided on one side of the swing frame 13 corresponding to the impact column 111, and the impact column 111 is connected and fixed through the arc groove 131. The impact column 111 is fixed by screws passing through the arc groove 131. The position of the impact column 111 can be adjusted accordingly, thereby adjusting the angle of the impact claw 112.

The mounting seat is installed on the separation cylinder 121 by screws. A row of springs are fixed on the mounting seat. A separation head 122 is distributed and fixed on each spring. The setting of the springs makes the separation head 122 work more reliably and can effectively perform secondary separation on the asphalt pavement damaged by the impact of the front-end impact claw 112, thereby avoiding the situation where the asphalt pavement is not completely separated, resulting in the rear end being unable to be cleaned well.

[0056] The crank-connecting rod mechanism 14 includes a crank shaft 141 installed at the output end of the driving mechanism I 16, and a connecting rod 142 is hingedly installed on the crank shaft 141. The other end of the connecting rod 142 is hinged to the swing frame 13, wherein the connecting rod 142 is a retractable elastic rod arrangement, and a compression spring is installed in the middle of the connecting rod 142 to prevent the impact claw 112 from rigidly impacting the ground, thereby reducing wear and damage to the equipment.

[0057] The support frame 15 is arranged in an I-shape, and the middle part is used for articulating the swing frame 13 . A support seat 151 is correspondingly installed at the upper end of the support frame 15 , and the support seat 151 is used for supporting the crank shaft 141 .

[0058] The cleaning assembly 42 includes a cleaning cylinder 421, on the outer surface of which cleaning brushes 422 are distributed. A crankshaft 141 is installed at the output end of the driving mechanism Ⅰ16, and one end of the crankshaft 141 away from the driving mechanism Ⅰ16 is connected to the cleaning cylinder 421 through a belt drive.

[0059] The collecting bin 35 is an arc-shaped plate matched with the cleaning brush 422 , a rubber plate is installed at the front end of the arc-shaped plate, and a conveyor belt 341 is provided at the rear end of the arc-shaped plate.

[0060] An output cleaning pulley 43 is installed at the end of the crank shaft 141, an input cleaning pulley 44 is installed at the end of the cleaning cylinder 421, a belt is installed between the output cleaning pulley 43 and the input cleaning pulley 44, and there is also an adjusting pulley 344 that cooperates with each other on the belt between the output cleaning pulley 43 and the input cleaning pulley 44.

An operating table 62 is correspondingly arranged on one side of the transparent window 61 . The transparent window 61 is a transparent plastic or transparent glass plate for viewing the conveying status of the conveyor belt 341 .

[0066] Working process or working principle:

[0067] like Fig.10 As shown, the road surface 7 is divided into a lower base layer 71, and an asphalt layer 72 is laid on the base layer 71. When potholes appear on the road surface, after cutting with a road surface cutting machine, the middle is an area to be removed 73.

[0068] When the equipment reaches the designated position, the electric cylinder 52 in the positioning component 5 is controlled to lower the swing frame 13, and the driving mechanism Ⅰ16 can be started accordingly. The driving mechanism Ⅰ16 drives the swing frame 13 to swing up and down, and the impact claw 112 crushes the area to be removed 73. The separation head 122 in the separation component 12 rotates during the up and down swinging process to perform secondary separation on the broken asphalt pavement, so as to achieve a better separation effect. The cleaning component 42 at the rear end pushes the broken asphalt pavement blocks from the collection bin 35 to the conveyor belt 341, and then sends them into the collection box 32.

[0069] The description of the direction and relative position relationship of the structure in the present invention, such as the description of front, back, left, right, up, and down, does not constitute a limitation of the present invention, but is only for the convenience of description.
