Description

Technical Field

[0001] This invention relates to the field of road shoulder slipforming technology, specifically a slipforming and casting device for highway earth road shoulders. Background Technology

[0002] "Roadside soil" is a common abbreviation in the highway engineering industry, generally referring to low-grade soil that can be used for filling roadbeds, shoulders, medians, etc. When forming road shoulders from roadside soil, a shoulder slipform paver is typically used. A typical shoulder paver consists of a storage bin, a feeder, a high-frequency vibrating forming mold, tracked tracks, and a diesel generator set. The roadside soil is shaped into a shoulder using the forming mold and vibration. During the compression forming process, the roadside soil first passes through crushing rollers and a screw conveyor, causing it to be crushed... After being crushed and laterally distributed by the screw conveyor, the material is arranged laterally. However, "longitudinal material fluctuation" may occur, that is, the amount of material entering the forming mold is uneven. This may result in some areas of the road shoulder being short of material during forming, which is quite inconvenient. In actual operation, some defective road shoulders may appear. If the defective road shoulder is short, it can be repaired by removing the defective road shoulder. However, the general repair method mostly relies on manual labor or excavators to remove the road shoulder and then use a rammer to repair it. This method relies on manual removal and the repair process is relatively complicated and inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide a slipform casting device for highway earth shoulders to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

A guide rail is fixedly connected to the bottom of each slider, and an agitation component is provided on each guide rail.

[0007] Furthermore, the agitation component includes:

[0008] The system comprises two sliding frames and two gearboxes. The tops of the two sliding frames are slidably engaged with the interior of adjacent guide rails. Multiple agitating rollers are rotatably connected to one side of the interior of each sliding frame. The multiple agitating rollers on the two sliding frames are arranged alternately. The two gearboxes are fixedly connected to the other side of the interior of each sliding frame. One end of each agitating roller passes through the adjacent gearbox. A connecting rod is rotatably connected between the top and bottom ends of each gearbox. A bevel gear is fixedly sleeved on the outer wall of each connecting rod and one end of the adjacent multiple agitating rollers. The bevel gear on each connecting rod meshes with the bevel gear on the adjacent agitating roller.

[0009] Furthermore, each guide rail is fixedly connected to both ends with a hydraulic push rod, and the movable ends of the two hydraulic push rods on each guide rail are fixedly connected to the top ends of the two adjacent slide frames, respectively.

[0010] Furthermore, each guide rail has a toothed plate fixedly connected to its top surface, each guide rail has two guide grooves, each agitator has two connecting rods that pass through the two guide grooves on the adjacent guide rails, each connecting rod has a drive gear fixedly sleeved at its top, and each toothed plate has teeth that mesh with the teeth of the two adjacent drive gears.

[0011] Furthermore, a motor box is fixedly connected to one end of the slide rail, and two drive motors are installed inside the motor box. The motor shafts of the two drive motors are respectively fixedly connected to one end of two screws.

[0012] Furthermore, multiple main hydraulic cylinders are fixedly connected to the top of the top shell, and the movable end of any one of the main hydraulic cylinders is fixedly connected to the slide rail.

[0013] Furthermore, the forming mechanism includes:

[0014] The system includes a pressure plate, a secondary hydraulic cylinder, and a smoothing frame for smoothing and shaping the road shoulder. The pressure plate is located between the two side plates and is J-shaped. A vibration box is installed above the pressure plate, and a vibration motor is installed inside the vibration box. The secondary hydraulic cylinder is fixedly connected to one end of the top shell, and a connecting shell is fixedly connected to the movable end of the secondary hydraulic cylinder. A shock absorber is installed between the connecting shell and the pressure plate. The smoothing frame is located below the connecting shell, and support arms are rotatably connected to both sides of the connecting shell.

[0015] Furthermore, each sliding frame has a baffle rotatably connected to the top of the other side via a pivot, each sliding frame is fixedly connected to a connecting box, each connecting box contains a swing cylinder, and the output end of each swing cylinder is fixedly connected to the adjacent pivot.

[0016] Furthermore, the top surface of the smoothing frame is provided with multiple counterweights, and one end of each side panel is fixedly connected with an inclined guide plate.

[0017] Furthermore, in the same stirring component, one of the sliding frames has slots at both the top and bottom, and the other sliding frame has protrusions fixedly connected to both the top and bottom. The protrusions slide and engage with the interior of the adjacent slots, and the bottom surface of any sliding frame is a slope.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. By using the top shell and mold mechanism to limit the road soil, and then using the dispersing mechanism to agitate the road soil, the road soil is evenly distributed. Then, the road soil is vibrated and compacted by the forming mechanism to form a road shoulder. When a defective road shoulder appears, the defective road shoulder can be cut and broken by the dispersing mechanism to restore the road shoulder to road soil. Then, the road soil is pre-compressed by the dispersing mechanism, and then the pre-compressed road soil is compacted and formed by the forming mechanism, which facilitates the reconstruction of the road soil.

[0020] 2. The height of the slide rail and two agitators can be adjusted by starting the main hydraulic cylinder. By starting the two drive motors, the screws and sliders can drive the two agitators to move along the slide rail, thereby adjusting the specific position of the agitators between the two side plates. When it is necessary to agitate the road soil, the hydraulic push rod on the agitator can be started to drive the adjacent slide frame to move back and forth, so that the two slide frames on the agitator move synchronously and in opposite directions to make transverse cuts. Then, the slide frames on the agitator cut into the soil layer during transverse cuts. At the same time, the movement of the slide frames can drive the drive gear to rotate by the tooth plate, so that the drive gear drives the adjacent agitator roller to rotate back and forth through the connecting rod and bevel gear. Then, the position of the agitator can be adjusted so that the agitator roller and the slide frame can agitate the soil layer to make the soil layer distribution more uniform.

[0021] 3. After the soil layer enters the space under the pressure plate, the vibration motor is started to drive the pressure plate to vibrate and compact the soil layer. The height of the pressure plate can be adjusted by starting the auxiliary hydraulic cylinder. When the pressure plate is compacting the soil layer, the swing cylinder can be started to make the baffle block the adjacent sliding frame. Then, the stirring mechanism is moved to make the baffle and sliding frame assist in pressing the soil layer under the pressure plate, so that the soil layer under the pressure plate is under pressure all around, improving the compactness of the road shoulder.

[0022] 4. When a defective shoulder appears, the vehicle body is moved to the defective shoulder, along with the two side plates and the top shell. Then, the cylinder is activated to move the two side plates, increasing the width between them. The positions of the two agitator components are then adjusted so that the sliding frames on the agitator components cut the two ends of the defective shoulder, separating it from the normal shoulder. The cylinder is then activated again to reset the side plates. The positions of the two agitator components are then adjusted to gradually move towards the center of the defective shoulder. The rotating agitator roller and the moving sliding frame break the defective shoulder into road soil, which is then vibrated and compacted again by the forming mechanism and mold mechanism to form a new road shoulder.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-7 In this embodiment of the invention, a slipform casting device for highway earth shoulders includes a slipform paver, comprising:

[0033] The system comprises a top shell 100, a mold mechanism 200 for confining the road soil, a forming mechanism 300 for shaping the road soil, and a dispersing mechanism 400 for agitating or cutting the road soil. A connecting piece for connection to a slipform paver is fixedly connected to one side of the top shell 100. The mold mechanism 200 is located inside the top shell 100 and includes two side plates 210. Multiple guide rails 110 are fixedly connected to the inner top surface of the top shell 100, and the top ends of both side plates 210 are slidably engaged with the multiple guide rails 110. Cylinders 220 are fixedly connected to opposite sides of the top shell 100 via connecting frames, and the movable ends of the two cylinders 220 are respectively fixedly connected to the two side plates 210. The forming mechanism 300... Located between the two side plates 210, the dispersing mechanism 400 includes a slide rail 410, and two sliders 412 are slidably engaged inside the slide rail 410. Two screws 411 are rotatably connected between the two ends of the slide rail 410. Each slider 412 has two circular through holes, and the two circular through holes on each slider 412 are slidably engaged with the two screws 411 respectively. An internal threaded cylinder is fixedly fitted inside one of the circular through holes on each slider 412, and the two internal threaded cylinders are screwed into the two screws 411 respectively. A guide rail 430 is fixedly connected to the bottom of each slider 412, and an agitation component is provided on each guide rail 430.

[0034] Specifically, the slipform paver is an existing highway shoulder slipform paver. It consists of a top shell 100, a mold mechanism 200, and a forming mechanism 300, forming the mold of the shoulder paver. In use, the shoulder paver spreads the highway soil in front of the top shell 100, which is connected to the vehicle body via connectors. The shoulder paver moves forward, allowing the highway soil to naturally enter between the two side plates 210. Then, by moving the two sliders 412, the positions of the two agitator components are adjusted, causing them to agitate the highway soil. Adjusting the positions of the two agitator components further moves them above the soil layer to scrape it. The soil is vibrated and compacted to form a road shoulder. During the road shoulder paving process, if defects occur in part of the road shoulder, the positions of the two agitators can be adjusted by moving the slider 412 so that the two agitators are located on opposite sides of the defective road shoulder. Then, the agitators cut the defective road shoulder, and the soil that makes up the defective road shoulder is broken up. If necessary, more soil is added manually, and then the agitators work with the forming mechanism 300 to reshape the soil into a road shoulder, which facilitates the paving of the soil road shoulder.

[0035] Example 1

[0036] like Figures 4-7 As shown, in this embodiment, the agitation component includes:

[0037] Two sliding frames 440 and two gearboxes 450 are provided. The tops of the two sliding frames 440 are slidably engaged with the interior of adjacent guide rails 430. Multiple agitating rollers 441 are rotatably connected to one side of the interior of each sliding frame 440. The multiple agitating rollers 441 on the two sliding frames 440 are arranged alternately. The two gearboxes 450 are respectively fixedly connected to the other side of the interior of each sliding frame 440. One end of each agitating roller 441 passes through the adjacent gearbox 450. A connecting rod 451 is rotatably connected between the top and bottom ends of the gearbox 450. A bevel gear is fixedly sleeved on the outer wall of each connecting rod 451 and one end of the multiple adjacent agitating rollers 441. The bevel gear on each connecting rod 451 meshes with the bevel gear on the adjacent agitating roller 441. Hydraulic push rods 432 are fixedly connected to both ends of each guide rail 430. Two hydraulic push rods 432 on each guide rail 430 are connected to the other end of each guide rail 430. The movable end of rod 432 is fixedly connected to the top of two adjacent slide frames 440 respectively. A toothed plate 431 is fixedly connected to the top surface of any guide rail 430. Two guide grooves are opened on the top surface of any guide rail 430. Two connecting rods 451 in any stirring component pass through the two guide grooves on the adjacent guide rail 430 respectively. A drive gear 452 is fixedly sleeved at the top of any connecting rod 451. The gear teeth on any toothed plate 431 mesh with the gear teeth of the two adjacent drive gears 452. A motor box 420 is fixedly connected to one end of slide rail 410. Two drive motors are installed inside the motor box 420. The motor shafts of the two drive motors are fixedly connected to one end of two screws 411 respectively. Multiple main hydraulic cylinders 470 are fixedly connected to the top of the top shell 100. The movable end of any main hydraulic cylinder 470 is fixedly connected to slide rail 410.

[0038] In this embodiment, the controller controls the opening and closing of two drive motors, which in turn drive two sliders 412 via screws 411. This allows the sliders 412 to adjust the positions of the two agitating components. A synchronous controller synchronously controls the opening and closing of multiple main hydraulic cylinders 470, which in turn move the slide rail 410, adjusting its height and that of the two agitating components. When the road soil enters between the two side plates 210, the height of the slide rail 410 is adjusted, causing the bottom of the sliding frame 440 on any agitating component to press into the road soil. As the sliding frame 440 presses into the road soil, the synchronous controller activates two hydraulic push rods 432 on the agitating component, causing them to move adjacent sliding frames 440 back and forth. This results in the two sliding frames 440 on any agitating component moving in opposite directions, allowing the sliding frames 440 to laterally cut the soil layer below, facilitating their entry into the road soil. Simultaneously, the sliding frames 440 move... At this time, the drive gear 452 on the adjacent gearbox 450 can roll on the toothed plate 431, thereby causing the drive gear 452 to drive the adjacent connecting rod 451 to rotate, thereby causing the connecting rod 451 to drive the adjacent multiple agitating rollers 441 to rotate reciprocally through the bevel gear. The agitating rollers 441 have protrusions on their surfaces to break up soil clods. After the sliding frame 440 enters the road soil, the two drive motors are started to drive the two agitating components to move reciprocally, causing the sliding frame 440 and the reciprocating rotating rollers 441 to move in opposite directions on the agitating components. The stirring roller 441 tumbles and breaks up the road soil. After tumbling, the stirring component can be moved above the soil layer to scrape the bottom of the sliding frame 440, making the soil layer more evenly distributed and the road soil more evenly distributed between the two side plates 210. Then, as the vehicle body moves the top shell 100, the road soil is naturally vibrated and compacted by the forming mechanism 300 to form a road shoulder. The sliding frame 440 is relatively high, and the top of the sliding frame 440 is always exposed outside the road soil.

[0039] In this embodiment, if a defective shoulder appears, the main hydraulic cylinder 470 is activated to detach the agitator from the soil layer. The vehicle body then moves the top shell 100 to the defective shoulder. The two agitators are then positioned on either side of the defective shoulder. The hydraulic push rod 432 drives the adjacent sliding frame 440 to move back and forth, causing the bottom of the sliding frame 440 to cut the shoulder laterally. Two cylinders 220 are activated to move the side plates 210 away from each other, increasing the space between the two side plates 210. This facilitates the sliding frame 440 cutting the shoulder, separating the defective shoulder from the normal shoulder. The position of the agitators is then moved and their height is continuously adjusted, causing the two agitators to gradually move towards the center of the defective shoulder. The moving sliding frame 440 and agitator roller 441 break up the defective shoulder. The cylinder 220 is then activated to reset the side plates 210, and new road soil is manually added from the gap between the top shell 100 and the shoulder, facilitating the repair of the defective shoulder.

[0040] like Figure 1 As shown, in this embodiment, the molding mechanism 300 includes:

[0041] The structure includes a pressure plate 310, an auxiliary hydraulic cylinder 320, and a smoothing frame 330 for smoothing and shaping the road shoulder. The pressure plate 310 is located between two side plates 210 and is J-shaped. A vibration box 311 is installed above the pressure plate 310, and a vibration motor is installed inside the vibration box 311. The auxiliary hydraulic cylinder 320 is fixedly connected to one end of the top shell 100. The movable end of the auxiliary hydraulic cylinder 320 is fixedly connected to a connecting shell 321, and a shock absorber 322 is installed between the connecting shell 321 and the pressure plate 310. The smoothing frame 330 is located below the connecting shell 321. Support arms 323 are rotatably connected to both sides of the connecting shell 321. One end of each support arm 323 is rotatably connected to the top surface of the smoothing frame 330. Multiple counterweights 331 are provided on the top surface of the smoothing frame 330. An inclined guide plate 211 is fixedly connected to one end of each side plate 210.

[0042] In practice, when the road soil enters the compaction plate 310, the vibration motor is started to drive the compaction plate 310 to vibrate, so that the compaction plate 310, together with the two side plates 210, vibrates and compacts the road soil. The height of the compaction plate 310 can be adjusted by starting the auxiliary hydraulic cylinder 320 through the controller. The shock absorber 322 is a spring-damped shock absorber 322, which reduces the impact of vibration on the auxiliary hydraulic cylinder 320 and the connecting shell 321. Then, as the vehicle moves, the smoothing frame 330 moves synchronously, so that the smoothing frame 330 smooths the road shoulder under the heavy pressure of the counterweight block 331.

[0043] like Figure 4 and Figure 7 As shown, in this embodiment, a baffle 460 is rotatably connected to the top of the other side of any sliding frame 440 via a rotating shaft, a connecting box 461 is fixedly connected to any sliding frame 440, a swing cylinder is provided inside any connecting box 461, and the output end of any swing cylinder is fixedly connected to the adjacent rotating shaft.

[0044] In practice, during normal shoulder paving, the swing assembly can be moved to detach from the soil layer, and then the swing cylinder can be activated to make the baffle 460 block the adjacent sliding frame 440. Then, the stirring assembly is inserted into the soil layer and presses the soil layer below the pressure plate 310. This causes the soil layer below the pressure plate 310 to be subjected to pressure from the pressure plate 310, the two side plates 210, the stirring assembly, the shaped shoulder, and the ground, thereby improving the compactness of the shoulder. The upward-curved end of the J-shaped pressure plate 310 is located between the two side plates 210, and the straight end is located outside the two side plates 210, thus preventing the soil layer from falling onto the pressure plate 310 when it is pushed.

[0045] In this embodiment, when repairing a defective shoulder, after the shoulder is broken and agitated by the agitating components, the position of the agitating components can be adjusted to detach them from the road soil. Then, the swing cylinder is activated to rotate the adjacent baffle 460, causing the baffle 460 to cover the adjacent sliding frame 440. The two agitating components are then moved to both ends of the defective shoulder. The baffle 460, along with the sliding frame 440, is then inserted into the soil layer. When the sliding frame 440 is inserted, it cuts the soil layer laterally to facilitate insertion. Furthermore, by moving the two agitating components to both ends of the defective shoulder, the sliding frame 440 and the baffle 460 press down on the soil layer, ensuring that the road soil is in close contact with the shoulder near the defective shoulder. Then, the two agitators pull out the soil layer and move it partially towards the center of the defective shoulder before re-inserting it into the soil layer. This process of pushing the soil layer towards both ends of the defective shoulder is repeated, allowing the agitators to repeatedly push, pull out, move towards the center of the defective shoulder, and re-insert the soil layer. This allows the road soil layer to be pre-compacted by the baffle 460 in sequence. Then, the vehicle body moves the forming mechanism 300, which uses the pressure plate 310 and side plate 210 to vibrate and compact the road soil. If the amount of soil is insufficient, road soil can be manually added to the shoulder between the two side plates 210. Then, by adjusting the position of the agitator, the upper sliding frame 440 and the baffle 460 push the newly added road soil to the defective shoulder.

[0046] Example 2

[0047] Based on Embodiment 1, the tightness of the two sliding frames 440 in the same agitation assembly is improved by setting slots and ridges.

[0048] like Figure 5 As shown, in this embodiment, one of the sliding frames 440 in the same stirring component has slots at both the top and bottom, and the other sliding frame 440 has protrusions fixedly connected to both the top and bottom. The protrusions slide and engage with the interior of the adjacent slots, and the bottom surface of any sliding frame 440 is a slope.

[0049] In practice, the two sliding frames 440 in the same agitator are interlocked by the convex strip and the slot, and the bottom ends of the two sliding frames 440 are in contact with each other. This makes it difficult for the bottom end of the sliding frame 440 to be embedded with foreign objects and open when cutting the soil layer. In addition, the inclined surface at the bottom end of the sliding frame 440 facilitates the sliding frame 440 to make transverse cuts on the road soil and road shoulders.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
