Description

Technical Field

[0001] This application relates to the field of road paving technology, and in particular to a road splicing and paving construction process. Background Technology

[0002] In the construction of highway reconstruction and expansion projects, due to differences in the construction time and settlement of new and old roads, the different requirements of new and old standards for road construction quality, and the significant differences in the processing technology and quality of materials from different eras, the quality of splicing construction, splicing position and size of newly built roads are greatly affected. Therefore, in the existing standards, the old road surface at the splicing point needs to be treated, and the splicing surface should be perpendicular to the road surface.

[0003] CN218667057U discloses a road surface cutting machine, including a machine body, a housing, a water tank, and a cutting blade. It also includes a first water pump, a second water pump, a switch, a filter device, a one-way valve, a dust cover, a water spraying device, and an atomizing nozzle. The water spraying device is composed of a universal joint and a threadedly fastened cylindrical adjustable nozzle. The cutting blade cuts the old road surface to define the location of the splicing surface.

[0004] Publication number CN213142739U discloses a dust removal system and a milling machine for a planer. The dust removal system includes: a first dust removal pipe, one end of which is connected to the space above the primary conveyor of the milling machine; a second dust removal pipe, located on the secondary conveyor of the milling machine, with its end away from the first dust removal pipe connected to the discharge port of the secondary conveyor; and a dust collection component, located on the secondary conveyor, with its first end connected to the first dust removal pipe and its second end connected to the second dust removal pipe. The dust collection component is used to draw dust from the first dust removal pipe into the second dust removal pipe. The dust collection component has multiple dust collection branch pipes extending to both sides of the receiving hopper of the secondary conveyor to draw dust from both sides of the receiving hopper into the second dust removal pipe. The milling machine then further breaks up the road surface on the side of the joint closest to the new road surface.

[0005] After crushing, the side of the cross-section closest to the new road surface is milled and leveled using a milling machine to form a cross-section splicing surface perpendicular to the road surface.

[0006] Regarding the aforementioned technologies, the inventors believe that in the process of processing spliced ​​surfaces, personnel first use a cutting machine to cut the road surface, and then use a milling machine to mill one side of the cut seam. This process requires multiple personnel to use two machines, which is inconvenient for moving the machines and also increases labor costs. Summary of the Invention

[0007] To mill a vertical splicing surface onto the road surface to be cut using a machine, this application provides a road splicing and paving construction process, employing the following technical solution: including the following steps:

[0008] s1: Pre-cutting treatment steps:

[0009] Clean up any debris from the road surface to be cut;

[0010] Plan the cutting locations on the road surface to be cut;

[0011] s2: Milling steps:

[0012] The road surface is milled using a milling machine, and the vertical cross-section formed by milling is the splicing surface;

[0013] s3: Lay asphalt on one side of the splicing surface, and wait for the asphalt to harden to form a new road surface;

[0014] The milling and planing device includes a bracket, a connector, a rotating assembly, a milling and planing assembly, and a drive assembly;

[0015] The connector slides linearly on the bracket;

[0016] The rotating assembly is rotatably connected to the connecting member, and the rotation axis of the rotating assembly on the connecting member is perpendicular to the sliding direction of the connecting member;

[0017] The milling assembly includes a cutter head slidably connected to the rotating assembly. The sliding direction of the cutter head on the rotating assembly is perpendicular to the rotation axis of the rotating assembly on the connector. The cutter head is connected to the rotating assembly via the driving assembly, which provides power for the sliding of the cutter head on the rotating assembly.

[0018] By adopting the above technical solution, the personnel first clean the road surface to be cut, then plan the cutting position on the road surface to be cut, then use a milling device to mill the road surface to be cut to form a splicing surface, and finally lay asphalt on one side of the splicing surface. After the asphalt solidifies, a new road surface is formed.

[0019] In the milling process: First, the drive assembly moves the cutter head away from the axis of rotation of the rotating assembly. Then, the rotating assembly rotates and drives the cutter head to break the road surface, forming an arc-shaped broken surface. After the breaking process is completed, the rotating assembly stops rotating, and the drive assembly drives the cutter head to be vertically inserted into the broken surface. Then, the connecting piece drives the rotating assembly to slide towards the side of the new road surface. The rotating assembly drives the cutter head to slide, thereby shaping the arc-shaped broken surface into a vertical splicing surface. Only one machine is needed to form the splicing surface.

[0020] Optionally, the cutting head is distributed in multiple rows along the circumferential direction of rotation of the rotating assembly and the connecting member on the rotating assembly.

[0021] By adopting the above technical solution, after the road surface is crushed by a row of cutters, the distance between the subsequent row of cutters and the rotation axis of the rotating component on the connecting piece is increased by the drive component, thereby gradually increasing the crushing and cutting depth and protecting the cutters.

[0022] Optionally, it also includes a linkage component, which includes a plurality of first links, the first links being slidably connected to the rotating component, the sliding direction being perpendicular to the rotation axis of the rotating component, a row of the cutter heads being mounted on one of the first links, and a drive component being connected between the first links and the connecting member, the drive component being used to drive the first links to slide on the rotating component.

[0023] By adopting the above technical solution, the drive component can drive a first connecting rod to slide on the rotating component, thereby driving a row of cutter heads to slide on the rotating component.

[0024] Optionally, the cutter head is divided into a crushing blade, which is a conical head, and the conical head of the crushing blade faces the side away from the rotation axis of the rotating assembly.

[0025] By adopting the above technical solution, a conical crushing blade is used in the crushing process to improve crushing efficiency.

[0026] Optionally, some of the blades are cutting blades with a cutting surface. When the cutting blade slides horizontally on the rotating assembly, the cutting surface is horizontal.

[0027] By adopting the above technical solution, a cutting blade is used in the cutting process to improve cutting efficiency.

[0028] Optionally, the cutter head is detachably connected to the first connecting rod via a mounting base.

[0029] By adopting the above technical solution, it is easier for personnel to replace the cutter head.

[0030] Optionally, the mounting base is provided with a plug-in slot, and the cutting head is fixed with a plug-in block that plugs into the plug-in slot.

[0031] By adopting the above technical solution, it is easier to improve the efficiency of personnel changing the cutting head.

[0032] Optionally, the drive assembly includes a sliding ring and at least one second link. The sliding ring slides on the rotating assembly, and the sliding direction is consistent with the rotation axis of the rotating assembly. One end of the second link is rotatably connected to one end of a first link, and the other end is rotatably connected to the sliding ring.

[0033] The rotating assembly has a driving assembly at each end of the rotation axis on the connector, and the two driving assemblies together drive the first connecting rod to slide.

[0034] By adopting the above technical solution, the two sliding rings slide in directions away from or close to each other. The sliding rings drive the second connecting rod to rotate on the sliding rings. The two second connecting rods together drive a first connecting rod to slide on the rotating assembly, thereby driving the cutter head to slide on the rotating assembly.

[0035] Optionally, the drive assembly further includes a third drive member mounted on the rotating assembly, the third drive member providing power for the sliding ring to slide on the rotating assembly.

[0036] By adopting the above technical solution, the third driving component drives the sliding ring to slide on the rotating assembly.

[0037] Optionally, the bracket is mounted on the vehicle body.

[0038] By adopting the above technical solution, it is easier for personnel to adjust the position of the milling and planing device.

[0039] In summary, this application includes at least one of the following beneficial technical effects:

[0047] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0048] This application discloses a road splicing and paving construction process.

[0049] A road surface splicing and paving construction process includes the following steps:

[0050] s1: Pre-cutting treatment steps:

[0051] Construction workers cleaned up debris from the road surface to be cut, and then drew the cutting lines on the road surface according to the design plan so that subsequent workers could carry out their work along the cutting lines.

[0052] s2: Milling steps:

[0053] Personnel use a milling device to mill along the cutting line on the road surface to be cut, and the resulting vertical cross-section serves as the splicing surface.

[0054] Reference Figure 1 , Figure 2 and Figure 3 The milling device includes a bracket 1, a connector 2, a rotating component 3, a milling component 4, and a drive component 5. The bracket 1 is mounted on the vehicle body 6, and the vehicle body 6 drives the milling device to the cutting line through the bracket 1.

[0055] Reference Figure 1 , Figure 2 and Figure 3In this application, the bracket 1 is rectangular, the connector 2 is linearly slidably connected to the bracket 1 along the first direction, and the rotating component 3 is rotatably connected to the connector 2. The rotating component 3 is parallel to the second direction along the rotation axis of the connector 2, and the second direction is perpendicular to the first direction. A first driving component 11 is installed on the bracket 1. In this application, the first driving component 11 is a cylinder. The body of the first driving component 11 is fixed to the bracket 1 by bolts. The output shaft of the first driving component 11 passes through the bracket 1 and is fixedly connected to the connector 2 so that the first driving component 11 drives the connector 2 to slide along the bracket 1, and the rotating component 3 slides with the connector 2.

[0056] The milling assembly 4 is slidably connected to the rotating assembly 3, and the milling assembly 4 is perpendicular to the rotation axis of the rotating assembly 3 along the connecting member 2 along the sliding direction of the rotating assembly 3. The driving assembly 5 provides power for the sliding of the milling assembly 4 on the rotating assembly 3.

[0057] Reference Figure 1 , Figure 2 and Figure 3 The rotating assembly 3 includes a rotating cylinder 31 and a second driving member 3432. In this embodiment, the rotating cylinder 31 is cylindrical. To increase the stability of the rotating cylinder 31, two brackets 1, two connectors 2, and two first driving members 11 are provided. Each bracket 1 is provided with a first driving member 11 and a connector 2 that is driven to slide along the bracket 1 by the first driving member 11. Both ends of the rotating cylinder 31 are coaxially welded with rotating shafts 33. Both ends of the rotating cylinder 31 are rotatably connected to a connector 2 through a rotating shaft 33. A second driving member 3432 is bolted to one side of the connector 2 away from the rotating cylinder 31. In this application, the second driving member 3432 is a motor. The output shaft of the second driving member 3432 is coaxially keyed to the rotating shaft 33.

[0058] Reference Figure 1 , Figure 2 and Figure 3 The milling assembly 4 includes a cutter head 41, which is slidably connected to the rotary drum 31. The sliding direction of the cutter head 41 on the rotary drum 31 is perpendicular to the axis of the rotary drum 31.

[0059] Reference Figure 1 and Figure 2 The cutter head 41 is provided in multiple rows. The multiple rows of cutter heads 41 are distributed along the circumferential direction of the rotating drum 31. Each row includes multiple cutter heads 41. The multiple cutter heads 41 in each row are distributed at intervals along a direction parallel to the rotation axis of the rotating drum 31. In this embodiment, the cutter heads 41 are provided in four rows.

[0060] Reference Figure 2 and Figure 3In order to drive the cutter head 41 to slide on the cylinder along a direction perpendicular to the cylinder's axis, the milling device also includes a linkage component 7. The linkage component 7 includes multiple first connecting rods 71, which are arranged parallel to the axis of the rotating cylinder 31. Specifically, in this embodiment, there are four first connecting rods 71, which are evenly distributed around the rotation of the rotating cylinder 31, and each first connecting rod 71 can slide along the rotating cylinder 31. In order to accommodate the first connecting rods 71 ​​and to allow the first connecting rods 71 ​​to slide along the rotating cylinder 31, four sliding grooves 311 are provided inside the rotating cylinder 31. Each first connecting rod 71 is located in one sliding groove 311 and can slide within the sliding groove 311. The two ends of the first connecting rod 71 extend out of the two ends of the rotating cylinder 31, and the first connecting rod 71 contacts the inner wall of the sliding groove 311 so that the inner wall of the sliding groove 311 guides the sliding of the first connecting rod 71. The sliding direction of the first connecting rod 71 in the sliding groove 311 is perpendicular to the axis of the rotating cylinder 31. In this embodiment, the purpose of setting the first link 71 is to drive multiple cutter heads 41 to move synchronously at one time. For this purpose, multiple cutter heads 41 in each row are fixedly connected to the same first link 71. Therefore, when any first link 71 slides, it can drive multiple cutter heads 41 connected to the first link 71 to slide synchronously.

[0061] Reference Figure 2 and Figure 3 In order to simultaneously drive multiple first connecting rods 71 ​​to slide, the milling device also includes at least one drive assembly 5. The drive assembly 5 includes a sliding ring 51 and at least one second connecting rod 52. The drive assembly 5 is connected between the rotating shaft 33 and the first connecting rods 71 ​​to realize the connection between the first connecting rods 71 ​​and the rotating shaft 33. Specifically, the sliding ring 51 is coaxially sleeved on the rotating shaft 33 and can slide along the axial direction of the rotating shaft 33. One end of the second connecting rod 52 is hinged to the first connecting rod 71 and the other end is hinged to the sliding ring 51. Therefore, when the sliding ring 51 slides along the rotating shaft 33, the first connecting rod 71 can be driven to slide along the rotating cylinder 31 through the second connecting rod 52.

[0062] Reference Figure 2 and Figure 3 Each drive assembly 5 may have one or more second connecting rods 52. When there is one second connecting rod 52 in the drive assembly 5, the sliding ring 51 moves and drives one first connecting rod 71 to move along the rotating drum 31. When there are multiple second connecting rods 52 in the drive assembly 5, the sliding ring 51 moves and can simultaneously drive multiple first connecting rods 71 ​​to slide along the rotating drum 31.

[0063] Reference Figure 2 and Figure 3Preferably, in this embodiment, a driving component 5 includes two second connecting rods 52, that is, a sliding ring 51 simultaneously drives two first connecting rods 71 ​​to slide; in order to ensure the smoothness of the sliding of the first connecting rod 71 along the rotating cylinder 31, each end of the first connecting rod 71 is connected to a second connecting rod 52, that is, each end of the first connecting rod 71 is driven by a driving component 5.

[0064] In addition, the other two first connecting rods 71 ​​in this application are also driven by a driving component 5 at each end; that is, in this application, each end of the rotating drum 31 is provided with two driving components 5. In order to ensure that the sliding rings 51 in the two driving components 5 at the same end of the rotating drum 31 can slide along the rotating shaft 33, the two sliding rings 51 at the same end of the rotating drum 31 are distributed along the axial direction of the rotating shaft 33, and the sliding rings 51 in the driving components 5 at the two ends of the first connecting rods 71 ​​are located on the side where the sliding rings 51 in the driving components 5 connected at the two ends of the other two first connecting rods 71 ​​are close to each other.

[0065] Reference Figure 1 , Figure 2 and Figure 3 Furthermore, in this application, the two first connecting rods 71 ​​connected to the same sliding ring 51 are distributed at a 180° angle in the circumferential direction of the rotating cylinder 31. That is, in the circumferential direction of the rotating cylinder 31, there is a first connecting rod 71 connected to another sliding ring 51 between the two first connecting rods 71 ​​connected to the same sliding ring 51.

[0066] Reference Figure 2 and Figure 3 In order to drive the sliding ring 51 to slide along the rotating shaft 33, the drive assembly 5 also includes a third drive member 53. In this application, the third drive member 53 is a cylinder. Each sliding ring 51 is connected to the rotating drum 31 through a third drive member 53. The cylinder body of the third drive member 53 is fixed to one end of the rotating drum 31. The output shaft of the third drive member 53 is fixedly connected to a sliding ring 51. The driving direction of the third drive member 53 is set parallel to the rotating shaft 33 of the rotating drum 31 so that the sliding ring 51 is driven by the third drive member 53 to slide along the rotating shaft 33.

[0067] Two third driving components 53 drive the two sliding rings 51 at both ends of the rotating drum 31 to move away from or closer to each other, thereby driving the second connecting rod 52 to rotate along the sliding rings 51. The second connecting rod 52 then drives the first connecting rod 71 to slide on the rotating drum 31.

[0068] Reference Figure 2 and Figure 3To facilitate the replacement and repair of the cutter head 41, each cutter head 41 in this application is connected to the first connecting rod 71 through a mounting base 72. Multiple receiving grooves 312 for accommodating the mounting bases 72 are provided on the rotating drum 31. Each mounting base 72 is located in a receiving groove 312 and can slide within the receiving groove 312 along the sliding direction of the first connecting rod 71 on the rotating drum 31. In order to connect the cutter head 41 to the mounting base 72, a plug-in groove 721 is provided on the mounting base 72. A plug-in block 411 is welded to one end of the cutter head 41 near the axis of the rotating drum 31. After the plug-in block 411 on the cutter head 41 is inserted into the plug-in groove 721 on the mounting base, the cutter head 41 is then fixed to the mounting base 72 by bolts.

[0069] Reference Figure 2 and Figure 3 In this embodiment, to facilitate the differentiation of multiple first connecting rods 71, two of the first connecting rods 71 ​​connected to the same sliding ring 51 are named crushing connecting rods, and the other two first connecting rods 71 ​​are named cutting connecting rods; the cutter head 41 connected to the crushing connecting rod through the mounting base 72 is called crushing cutter 412, and the cutter head 41 connected to the cutting connecting rod through the mounting base 72 is called cutting cutter 413; therefore, the distribution of crushing cutter 412 and cutting cutter 413 on the rotating drum 31 is as follows: in two adjacent rows of cutter heads 41, one row of cutter heads 41 is crushing cutter 412, and the other row of cutter heads 41 is cutting cutter 413.

[0070] Reference Figure 2 and Figure 3 The crushing blade 412 is a conical blade head 41, with the cone head facing away from the axis of the rotating drum 31, so as to facilitate the crushing of the road surface and improve construction efficiency; the cutting blade 413 is provided with a cutting surface 4131, and when the cutting blade 413 slides horizontally on the rotating drum 31, the cutting surface 4131 is also horizontal.

[0071] Reference Figure 1 , Figure 2 and Figure 3 A reserved gap is formed between the cutter heads 41 on two adjacent mounting seats 72 on the same first link 71.

[0072] Reference Figure 1 , Figure 2 and Figure 3 For ease of description, we name the first set of working blades as one row of crushing blades 412 and one row of cutting blades 413 in two adjacent rows of blades 41, and the second set of working blades as two adjacent rows of crushing blades 412 and cutting blades 413. We also name the circumference where the blades 41 are located as the reference circle. On the reference circle, the blades 41 in the first set of working blades are located on the reference circle, and the reserved gap formed by the second set of working blades is located on the reference circle.

[0073] When using the above-mentioned milling device to mill the road surface, the specific steps include the following:

[0074] Phase 1: Preparation phase, at which time the crusher 412 is located outside the rotating drum 31 and the cutting blade 413 is located inside the rotating drum 31;

[0075] Second stage: Crushing stage. The second driving component 34 drives the rotating drum 31 to rotate, and the rotating drum 31 drives the crushing blade 412 to rotate. The crushing blade 412 contacts the road surface and crushes the road surface. The crushing blade 412 crushes the road surface with the cutting surface 4131 into an arc-shaped crushed surface. After the rotating drum 31 rotates one revolution, the third driving component 53 drives the sliding ring 51 to slide. The sliding ring 51 drives the crushing connecting rod to slide on the rotating drum 31 through the second connecting rod 52. The crushing connecting rod drives the crushing blade 412 to move away from the axis of the rotating drum 31, thereby increasing the crushing radius. The rotating drum 31 rotates again.

[0076] The third stage: the cutting stage. Once the vertical depth of the arc-shaped fracture surface broken by the breaker 412 is sufficient, the third drive component 53, which drives the breaker 412, slides the breaker 412 into the rotating drum 31. Then, the second drive component 3432 drives the cutting blade 413 to rotate directly above the arc-shaped fracture surface. This causes the third drive component 53, which moves the cutting linkage, to begin operating, vertically inserting the cutting surface 4131 of the cutting blade 413 into the arc-shaped fracture surface. Subsequently, the first drive component 11 drives the connecting component 2 to slide on the support 1 along a length parallel to the road surface. The connecting component 2 then... The rotating drum 31 drives the cutting blades 413 to shape the arc-shaped broken surface into a vertical splicing surface. After one row of cutting blades 413 finishes working, the third drive member 53 drives the cutting blades 413 to retract above the road surface. The first drive member 11 drives the rotating drum 31 to return to its initial position. Then, the second drive member 3432 drives the rotating drum 31 to rotate. When the other row of cutting blades 413 rotates to the point where the cutting surface 4131 is perpendicular to the road surface, the third drive member 53, which drives the cutting linkage, starts to work. This process is repeated to cut the arc-shaped broken surface to form a vertical splicing surface.

[0077] s3: After the splicing surface is processed, personnel begin to lay asphalt on the side of the splicing surface away from the road surface to be cut. After the asphalt hardens, a new road surface is formed, thus splicing the old and new road surfaces together. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
