Description

Technical Field

[0001] The invention relates to the technical field of road construction, and in particular to a traffic engineering road repairing device. Background Art

[0002] Traffic engineering road repair equipment is a special equipment used to repair and maintain road surface damage. Its design and function are aimed at improving the efficiency and quality of road repair. It includes road repair machines, excavators, rollers, pavers, concrete mixing plants and mixer trucks. Road repair machines are mainly used to repair damaged parts of existing roads, such as cracks, potholes and other defects, to ensure the normal use of roads. According to different repair methods, road repair machines can be divided into two types: cold mix road repair machines and hot mix road repair machines. Before construction, the road surface needs to be thoroughly cleaned to remove dust, debris and loose asphalt particles. For wider cracks, grooves need to be opened first to better fill the repair agent. Spray or brush the repair agent evenly on the road area that needs to be repaired. Compact the repaired road surface to improve the density and stability of the repair layer.

[0003] After filling the materials, the existing road repair devices need to roll and compact the materials, but the existing rolling methods are often manual, which will lead to inconsistent rolling time at various positions in the horizontal direction, resulting in inconsistent rolling compaction at various positions, affecting the quality of road repair. In addition, due to the uneven repair range, there will be time differences at various positions during rolling, which will cause uneven horizontal movement of the internal materials when each position is subjected to rolling pressure, which will also lead to inconsistent rolling compaction at various positions in the horizontal direction. In the vertical direction, the density of the material close to the bottom of the pit is usually greater than the density of the material close to the road surface, so conventional filling and compaction will lead to reduced repair quality of the repaired road surface.

[0004] For example, the Chinese invention patent with the announcement number CN111809494B provides a road repair cutting machine, which integrates the two operations of cutting and drilling by setting a cutting mechanism and a drilling mechanism. However, when the material is squeezed after filling, the problem of uneven squeezing in the horizontal and vertical directions still occurs. Summary of the invention

[0016] Furthermore, the square frames are square in shape, and each square frame matches the shape of its corresponding square groove.

[0024] Since the side wall of the roadbed has a weaker supporting effect on the material as it is closer to the center of the square groove, the annular cone bars that gradually rise and widen from the outside to the inside increase the contact area between the material and the original road surface material. The annular cone bars provide horizontal support for the material, reducing the horizontal displacement of the filler at the square groove when the road surface is compressed later, making the material more evenly compressed and having a better compression effect. When the road surface after filling and extrusion is rolled by vehicles, due to the presence of the annular cone bars, the pressure on the top of the filler will cause the bottom filler to gather to reduce the downward movement space of the top filler. Since the top filler is compressed first, the horizontal movement space of the top filler is also reduced, and the repaired road surface is less likely to collapse under pressure.

[0025] Filler compaction stage: In the initial state, the upper side of the complete plate and the upper side of the trapezoidal plate are inclined toward the middle of the square frame. First, the vertical sides of the square frame and the annular cone bar are butted against each other, and the complete plate and the trapezoidal plate are butted against the hypotenuse of the annular cone bar. After that, after the material is put into the square groove where the hypotenuse of the annular cone bar is located, the complete plate and the trapezoidal plate are rotated so that the complete plate and the trapezoidal plate are gradually set vertically, and the material is flattened. The horizontal compaction unit flattens the material, thereby completing the horizontal and vertical extrusion, making the material more compacted. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Reference Figures 1 to 7 As shown, a traffic engineering road repair device provided by an embodiment of the present invention is used to be installed on a repair vehicle 100, and includes a cutting mechanism and a compacting mechanism. The cutting mechanism includes a tool holder 308, a cutting assembly, and a transmission assembly. The tool holder 308 is horizontally slidably arranged on the repair vehicle 100, and the cutting assembly includes a vertical cutting wheel 304 and a bevel cutting wheel 303. Both the vertical cutting wheel 304 and the bevel cutting wheel 303 are arranged on the tool holder 308 so as to be able to move up and down. The axial direction of the vertical cutting wheel 304 is arranged in the horizontal direction, and the bevel cutting wheel 303 is arranged obliquely. The distance between the upper end of the vertical cutting wheel 304 and the upper end of the bevel cutting wheel 303 is greater than the distance between the lower end of the vertical cutting wheel 304 and the lower end of the bevel cutting wheel 303. Both the vertical cutting wheel 304 and the bevel cutting wheel 303 can rotate around their own axes.

[0037] The transmission assembly drives the cutting assembly to move along multiple square paths on the road surface. The multiple square paths are concentrically arranged. From the outside to the inside, the distance between two adjacent square paths gradually increases. The vertical cutting wheel 304 and the bevel cutting wheel 303 cut multiple concentrically arranged square grooves 200 on the road surface from the outside to the inside. From the top to the bottom, the width of the square grooves 200 gradually decreases. After the multiple square grooves 200 are cut on the road surface, multiple annular cone bars 210 are formed between two adjacent square grooves 200 at the bottom of the roadbed. The height of the annular cone bars 210 gradually increases from the outside to the inside, and the width of the annular cone bars 210 gradually increases from the outside to the inside.

[0038] Since the inclination angle of the bevel wheel 303 remains unchanged, the vertical cutting wheel 304 and the bevel wheel 303 descend to the same height when cutting the road surface. Therefore, the wider the cut square groove 200 is, the wider the annular cone strip 210 is, and the higher the height is.

[0039] The compaction mechanism includes a mounting frame 407 and a plurality of compaction assemblies. The mounting frame 407 is rotatably mounted on the repair vehicle 100. The plurality of compaction assemblies are distributed along the circumference of the mounting frame 407, and each compaction assembly includes a horizontal compaction unit and a vertical compaction unit. The vertical compaction unit includes a square frame 404 and two complete plates 401 and two trapezoidal plates 402. The square frame 404 is slidably mounted on the mounting frame 407, and each square frame 404 is disposed in a square slot 200.

[0040] The complete plate 401 and the trapezoidal plate 402 are arranged along the up-down direction, and the lower side of the complete plate 401 and the lower side of the trapezoidal plate 402 are both rotatably connected to the square frame 404. The two complete plates 401 and the two trapezoidal plates 402 are alternately arranged along the circumference of the square frame 404, and each trapezoidal plate 402 is used to abut against the two complete plates 401. The horizontal compaction unit is used to compact the material in the square trough 200 in the horizontal direction.

[0041] The traffic engineering road repair device includes a cutting stage and a filler compaction stage. In the cutting stage, the vertical cutting wheel 304 and the bevel cutting wheel 303 are driven by the transmission assembly to move from outside to inside along multiple paths, and the vertical cutting wheel 304 and the bevel cutting wheel 303 cut multiple square grooves 200 on the road surface, and multiple annular cone bars 210 are formed on the bottom of the roadbed, and the longitudinal section of the annular cone bar 210 is a right triangle.

[0042] Since the support effect of the side wall of the roadbed on the material is weaker as it is closer to the center of the square groove 200, the annular cone bar 210, which gradually rises and widens from the outside to the inside, increases the contact area between the material and the original road surface material. The annular cone bar 210 provides horizontal support for the material, reduces the horizontal displacement of the filler at the square groove 200 when the road surface is compressed later, and makes the material more evenly compressed, and the compression effect is better. When the road surface after filling and extrusion is rolled by a vehicle, due to the presence of the annular cone bar 210, the pressure on the top of the filler will cause the bottom filler to gather, so as to reduce the downward movement space of the top filler. Since the top filler is compressed first, the horizontal movement space of the top filler is also reduced, and the repaired road surface is less likely to collapse under pressure.

[0043] Filler compaction stage: In the initial state, the upper side of the complete plate 401 and the upper side of the trapezoidal plate 402 are both inclined toward the middle of the square frame 404.

After that, after the material is put into the square groove 200 where the hypotenuse of the annular cone bar 210 is located, the complete plate 401 and the trapezoidal plate 402 are rotated so that the complete plate 401 and the trapezoidal plate 402 are gradually set vertically, and the material is flattened, and the horizontal compaction unit flattens the material, thereby completing the horizontal and vertical extrusion, so that the material is pressed more tightly.

[0044] In this embodiment, the vertical compaction unit has a first state and a second state. The first state of the vertical compaction unit is that the complete plate 401 and the trapezoidal plate 402 are arranged vertically. The second state of the vertical compaction unit is that the complete plate 401 and the trapezoidal plate 402 are arranged obliquely, and the upper side of the complete plate 401 and the upper side of the trapezoidal plate 402 are both close to the middle of the square frame 404. When the vertical compaction unit rotates from the second state to the first state, the material is squeezed.

[0045] Each trapezoidal plate 402 is provided with first inclined surfaces on both sides close to the complete plate 401, and the two first inclined surfaces gradually move away from each other from top to bottom, and the first inclined surfaces are used to abut against the complete plate 401. Each trapezoidal plate 402 is provided with a mounting groove, and when the vertical compaction unit is in the first state, the mounting groove is vertically arranged.

[0046] Each first inclined surface is provided with a protruding plate 403, which is arranged parallel to the trapezoidal plate 402.

As the square slots 200 move from outside to inside, the areas of the square frames 404 decrease and the heights of the square frames 404 increase. The height of the square frame 404 matches the depth of the square slot 200, that is, the upper end of the square frame 404 is flush with the upper end of the annular cone bar 210 that abuts against it.

[0059] Cutting stage: first move the cutting mechanism to the desired cutting position. In the initial state, the slider 305 on the tool holder 308 is in the first slide groove 3011 farthest from the second rotating shaft 302 .

[0060] The first power source 3061 is started, and the first power source 3061 drives the first power roller 306 to rotate. Since the first power roller 306 and the connecting plate 301 are in frictional contact, the first power roller 306 drives the tool holder 308 to move along the first direction when it rotates, and the slider 305 slides in the first slide groove 3011.

The waste material generated by the cutting is manually removed. After the tool holder 308 moves from one end of the first slide groove 3011 to the other end, the second motor is started, and the second motor drives the second rotating shaft 302 to rotate, and the second rotating shaft 302 drives the connecting plate 301 to rotate until the vertical cutting wheel 304 and the bevel cutting wheel 303 cut out four material discharge grooves on the road surface, and the four material discharge grooves form the first square groove 200.

[0062] After that, the second power source 3071 is started, the second power source 3071 drives the second power roller 307 to rotate, the second power roller 307 drives the slider 305 to enter the second slide groove 3012, and then the slider 305 enters the next first slide groove 3011 through the first power roller 306. The vertical cutting wheel 304 and the bevel cutting wheel 303 cut the second square groove 200 on the road surface, and then cut the third square groove 200 and the last square groove 200 in sequence. The first square groove 200 has the largest area, and the last square groove 200 has the smallest area.

[0063] Since the distance between two adjacent first chutes 3011 increases along the second direction and closer to the second rotating shaft 302, the width of the multiple discharge troughs cut out increases as they approach the center of the square trough 200, and the upper end of the discharge trough is closer to the road surface.

[0064] The bottom of the roadbed is cut into an annular cone bar 210, and the slope of the annular cone bar 210 is the same from the outside to the inside, the height of the annular cone bar 210 gradually increases from the outside to the inside, and the width of the annular cone bar 210 gradually increases from the outside to the inside. Since the side wall of the roadbed has a weaker supporting effect on the material closer to the center of the square groove 200, the annular cone bar 210 that gradually rises and widens from the outside to the inside increases the contact area between the material and the original road surface material. The annular cone bar 210 provides horizontal support for the material, reduces the horizontal displacement of the filler at the square groove 200 when the road surface is compressed in the later stage, and makes the material more evenly compressed, and the compression effect is better.

[0065] When the road surface after filling and extrusion is rolled over by vehicles, due to the presence of the annular cone bar 210, the pressure on the top of the filler will cause the bottom filler to gather, so as to reduce the downward movement space of the top filler. Since the top filler is compressed first, the horizontal movement space of the top filler is also reduced, and the repaired road surface is less likely to collapse under pressure.

[0066] Filler compaction stage: After cutting, the compaction mechanism is first moved to the square groove 200. In the initial state, the vertical compaction unit is in the second state, and the extended plate 403 is in the installation groove. The longitudinal section of the square groove 200 is an inverted right triangle, and the complete plate 401 and the trapezoidal plate 402 are parallel to the hypotenuse of the inverted right triangle.

[0067] First, place the square frame 404 with the largest area in the second square slot 200. Feed materials into the first square slot 200 through the feed hopper 409. Start the second hydraulic cylinder 405 and the third hydraulic cylinder 406, which drive the complete plate 401 and the ladder plate 402 to gradually vertically set up and flatten the materials. Start the fourth hydraulic cylinder 410, which drives the horizontal pressing plate 408 to move downward and compact the materials so that the materials are flush with the road surface.

[0068] Then the first rotating shaft 420 is rotated, the first rotating shaft 420 drives the mounting frame 407 to rotate, the mounting frame 407 drives another compacting assembly to rotate into the square slot 200, the square frame 404 in another vertical compacting unit is in the third square slot 200, the material is put into the second square slot 200, and another horizontal compacting unit compacts the material in the second square slot 200, until multiple square slots 200 are filled in sequence, and the last square slot 200 is manually filled and compacted. The square slots 200 are filled in batches so that the area where each square slot 200 is located can be filled evenly, and the material is squeezed horizontally and vertically to make the material more compacted.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
