Description

Technical Field

[0001] This invention relates to the field of in-situ regeneration technology for asphalt pavements, specifically a high-frequency vibration scraping device. Background Technology

[0002] In-situ recycling of asphalt pavement refers to recycling without reducing the grade and layer of the recycled pavement, while maintaining the original gradation. The self-recycling capacity of RAP (recycled asphalt material) determines the degree of utilization of RAP in the in-situ recycling process.

[0003] The self-regeneration capacity of RAP (Rapid Asphalt Pavement) depends on both the damage condition of the original pavement and the asphalt pavement removal process. Designing a reasonable new removal process to minimize damage to the aggregates in RAP and maximize its self-regeneration capacity can lay the technical foundation for in-situ regeneration of asphalt pavements. Milling and loosening are two common asphalt pavement removal techniques. Milling and crushing involves using a milling machine's cutter to break up the old road surface and remove it from the original surface. The milled mixture is then transported to trucks using the inertia of the rotating cutter and a conveying device. The entire process is streamlined and automated, allowing crushing and loading to be carried out simultaneously. This results in continuous operation, high efficiency, and meets the requirements of modern construction. However, the gradation curve of the recycled material is severely damaged, leading to a low recycling rate. Loosening and crushing mainly involves demolition using machinery such as excavator breakers and bulldozer rippers. The extrusion of the drill bit and the tilling of the ripper cause the road material to be squeezed and deformed, resulting in cracks. The crushed road material is then loaded onto trucks by loaders and other machinery. Compared with milling and crushing, aggregate crushing is reduced. However, the crushing thickness and the smoothness of the crushed road surface cannot be precisely controlled, and it is only suitable for overall road surface crushing.

[0004] To address this, we propose a high-frequency vibratory scraping device capable of non-destructively removing old asphalt pavement materials, especially surface layer materials. Summary of the Invention

[0005] One of the technical problems this application aims to solve is how to remove old asphalt pavement materials, especially surface layer materials, without damage.

[0010] In some embodiments, the protective cover body consists of a main protective cover and a secondary protective cover, both of which are provided with rollers at their bottoms, and a flexible connecting layer is provided between the main protective cover and the secondary protective cover.

[0011] In some embodiments, a rotating seat one is provided on the main protective cover, and a rotating seat two is provided on the secondary protective cover. The rotating seat one and the rotating seat two are provided with fixing holes, and a plug-in bolt passes through the fixing holes. An adjusting nut and a fixing nut are sequentially threaded onto the plug-in bolt, and a detection component is provided between the main protective cover and the secondary protective cover.

[0012] In some embodiments, the detection component includes fixed plates disposed on both sides of a rotating seat, a pressing rod slidably disposed inside each fixed plate, a return spring sleeved on the outer side of each pressing rod, and a blocking plate disposed on the outer side of each pressing rod.

The impact blade is driven by a high-frequency hydraulic impact device to perform high-frequency vibration cutting. This method can efficiently break the asphalt pavement structure while avoiding excessive crushing or thermal damage to the old asphalt material (especially the surface aggregate), thus maximizing the preservation of the physical properties of the raw materials and providing high-quality raw materials for subsequent recycling.

Detailed Implementation

[0018] 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.

[0019] Example 1: Please refer to Figures 1-17 The present invention provides a technical solution: A high-frequency vibration shoveling device includes a traveling carriage 1, a tool holder 2, and an impact shovel 3. A support frame 4 is provided at the front of the traveling carriage 1. A rotation adjustment component 5 is provided between the support frame 4 and the tool holder 2. A depth adjustment component 6 is provided on the rotation adjustment component 5. A high-frequency hydraulic impact device 7 is provided on the tool holder 2. The impact shovel 3 is located at the front end of the high-frequency hydraulic impact device 7. A limiting seat 10 for guiding the impact shovel 3 is provided on the tool holder 2. In this design, the traveling vehicle 1 uses a common existing engineering vehicle, which will not be described in detail. The support frame 4 is located at the front of the traveling vehicle 1, providing installation support for subsequent structures. The high-frequency hydraulic impact device 7 consists of an impact system and a rebound absorption system, as shown in the attached diagram. Figure 3 As shown: The impact system is a key part of the hydraulic impact device. It consists of main components such as cylinder, impact piston, reversing valve, gear adjustment plug, accumulator, and guiding and sealing devices. When the hydraulic pump provides pressurized oil, the reversing valve controls the impact piston to reciprocate and impact the blade handle, converting the pressure energy of the liquid into the impact energy of the impact piston. The impact energy is then transmitted to the road surface in the form of stress waves through the blade, causing the road surface to be removed.

[0020] The rebound absorption system consists of a body, a buffer piston, and a buffer bushing. When the impact piston completes its impact and begins its return stroke, the rebound force of the blade is transmitted to the buffer piston. The buffer piston rebounds and absorbs the rebound energy under the action of the pressure oil in the buffer chamber, causing the buffer piston to decelerate. Therefore, the rebound absorption system plays a role in protecting the impact device.

[0021] Working principle of the impact system: (1) Return motion: As attached Figure 4 As shown, the impact piston has completed its previous impact process, the directional valve has ended its reversing motion, and the entire impact system is in the initial return state. At this time, the pressure oil (Qi) input by the hydraulic pump passes through the valve port f and oil passage (Qp1) of the directional valve and reaches the front chamber V1 of the piston. The pressure oil acts on the working surface A1 of the impact piston, pushing the impact piston to perform a return acceleration motion. The low-pressure oil in the rear chamber V2 of the piston passes through the oil passage (Qp2) and the valve port h of the directional valve, connecting with the return oil circuit. When the piston continues to return to a certain position, the signal hole c opens, and the oil in the left chamber V3 of the directional valve passes through the oil passage (Qv1), connecting with the return oil circuit, and the directional valve prepares to reverse.

[0022] The impact piston continues its accelerated return motion, causing signal port a to open, as shown in the attached diagram. Figure 5As shown, the high-pressure oil in the piston's front chamber V1 connects to the right chamber V4 of the directional control valve via the oil passage (Qv2) of the gear adjusting plug. The pressure oil acts on the right end face A4 of the directional control valve, pushing it to begin its leftward reversing motion. When the directional control valve's moving ports e and g open, and ports f and h close, the piston's front chamber V1 connects to the return oil circuit, and the piston's rear chamber V2 connects to the pressure oil (Qi). At this time, the piston's rear end face A2 undergoes a return deceleration motion under the action of the pressure oil until it stops moving.

[0023] (2) Stroke motion: As attached Figure 6 As shown, after the return stroke, the rear end face A2 of the impact piston begins to accelerate under the action of pressurized oil. The piston moves forward to the signal hole b, which opens. The oil in the right chamber V4 of the reversing valve connects to the return oil circuit through the oil passage (Qv2) of the gear adjusting plug, preparing for reversing. The piston continues to accelerate to the signal hole d, which opens. The pressurized oil in the rear chamber V2 of the piston connects to the left chamber V3 of the reversing valve through the oil passage (Qv1). The pressurized oil acts on the left end A3 of the reversing valve, pushing the reversing valve to begin reversing to the right. The piston remains in the stroke state until it impacts the drill bit.

[0024] As attached Figure 7 As shown, when the reversing valve moves to the right, and the valve ports e and g are closed, and f and h are opened, and the piston front chamber V1 is connected to the high-pressure oil, if the piston has not yet struck the tail, the piston will begin to perform a stroke deceleration motion under the action of the pressure oil, and repeat the return motion described in (1) after striking the tail. If the piston has struck the tail before the valve ports e and g are closed and f and h are opened, the piston will have multiple impacts under the combined action of the high-pressure oil and the rebound force of the tail until the energy is balanced. Then the reversing valve moves to open the f and h ports, and the piston begins the return motion described in step (1).

[0025] The rotation adjustment component 5 includes a drive motor 51 mounted on the support frame 4. A drive shaft 52 and a transmission shaft 53 are rotatably mounted on the support frame 4. The drive shaft 52 is connected to the output end of the drive motor 51. A drive gear 54 is mounted on the drive shaft 52. A transmission gear 55 that meshes with the drive gear 54 is mounted on the transmission shaft 53. A swing frame 56 is mounted on the transmission shaft 53. The depth adjustment component 6 is mounted on the swing frame 56. The drive motor 51 starts and drives the drive shaft 52 to rotate. Through the meshing between the drive gear 54 and the transmission gear 55, the transmission shaft 53 and the swing frame 56 are driven to rotate and adjust. The angle between the impact blade 3 and the ground is the cutting angle. In this scheme, the rotation range of the cutting angle is designed to be between 10° and 20°, preferably 15°.

[0026] The tool holder 2 is slidably mounted on the swing frame 56. The depth adjustment component includes a fixed seat 61 mounted on the swing frame 56. A screw 62 is threadedly connected to the fixed seat 61. A connecting frame 63 is mounted on the tool holder 2. One end of the screw 62 is rotatably connected to the connecting frame 63 via a bearing. A turntable is mounted on the end of the screw 62 away from the connecting frame 63. Multiple fastening bolts are mounted on the swing frame 56. Because the tool holder 2 slides within the swing frame 56 and the impact scraper 3 slides within the tool holder 2, the scraping angle of the impact scraper 3 can be controlled after the swing frame 56 is adjusted. Then, multiple fastening bolts are loosened, and the screw 62 is rotated by rotating the turntable, so that the connecting frame 63 and the tool holder 2 are adjusted accordingly within the swing frame 56 to achieve the target scraping depth. Then, the turntable is loosened and multiple fastening bolts are tightened to achieve the positioning of the tool holder 2. The secondary positioning by the fastening bolts can avoid the high-frequency vibration from affecting the accuracy of the screw 62 and ensure subsequent precise adjustment.

[0027] The impact shovel 3 includes a blade holder 31 disposed at the front end of the high-frequency hydraulic impact device 7. A blade head 32 is detachably disposed on the blade holder 31. The limiting seat 10 includes a guide seat 11 disposed on the blade holder 2. Counterweights 12 are detachably disposed on both sides of the guide seat 11. The blade holder 31 is slidably disposed in the guide seat 11. The blade head 32 is mounted on the blade holder 31 by bolts. The counterweights 12 are mounted on the guide seat 11 and the blade holder 2 by bolts. However, the mounting method is not limited to bolt mounting; other detachable mounting methods are also possible. The guide seat 11 can guide and limit the blade holder 31, effectively ensuring the accuracy of the blade reciprocating motion. The design of the counterweight 12 can balance the high-frequency vibration during operation, avoid the tip lifting phenomenon, improve the overall stability of the equipment, ensure the accuracy of the cutting trajectory, reduce the fatigue damage of vibration to the equipment body, and extend the life of key components.

[0028] In use, the drive motor 51 starts and drives the drive shaft 52 to rotate. Through the meshing between the drive gear 54 and the transmission gear 55, the transmission shaft 53 and the swing frame 56 are rotated and adjusted to adjust the angle between the impact blade 3 and the ground to 15°. Then, the target cutting depth of the impact blade 3 is adjusted. Specifically, the screw 62 is rotated by rotating the turntable, so that the connecting frame 63 and the blade holder 2 slide downward within the swing frame 56 to achieve the target cutting depth. Then, the turntable is loosened and multiple fastening bolts are tightened to position the blade holder 2. The secondary positioning by the fastening bolts can avoid the high-frequency vibration from affecting the accuracy of the screw 62 and ensure the subsequent accurate adjustment. Finally, the traveling vehicle 1 starts, the high-frequency hydraulic impact device 7 starts, and the impact system and rebound absorption system start working, driving the impact blade 3 to scrape the asphalt ground. During the process, the blade holder 31 slides back and forth in the guide seat 11 to avoid deviation of the impact blade 3 head 32.

[0029] Example 2: Please refer to Figures 11-17 The present invention provides a technical solution: A high-frequency vibration scraping device includes telescopic rods 13 on both sides of the bottom of the tool holder 2. A connecting spring 14 is sleeved on the outside of each telescopic rod 13. A fixed support 15 is provided at the bottom of each telescopic rod 13. A sliding strip 16 is slidably arranged inside each fixed support 15. A protective cover body 8 is provided on the outside of the two sliding strips 16. The fixed support 15 and the sliding strip 16 are interference-fitted. An eight-shaped lever is provided at the bottom of the fixed support 15 to guide the scraped waste to both sides of the traveling vehicle 1 to avoid affecting the tire trajectory of the traveling vehicle 1. The design of the telescopic rod 13 and the connecting spring 14 ensures that the fixed support 15 can adapt to the needs of different target cutting depths, thereby ensuring that the protective cover body 8 is stably installed on the fixed support 15. During installation, simply insert the sliding strip 16 inside the protective cover body 8 into the fixed support 15. Since the fixed support 15 and the sliding strip 16 are interference fit, they can be effectively limited.

[0030] The protective cover body 8 is composed of a main protective cover 81 and a secondary protective cover 82. Both the main protective cover 81 and the secondary protective cover 82 are provided with rollers at their bottoms, and a flexible connecting layer is provided between the main protective cover 81 and the secondary protective cover 82.

[0031] Because the cutter head 32 is designed to be detachable, different sizes of cutter heads 32 can be replaced according to the road conditions. Therefore, the size of the auxiliary guard 82 in this solution is not unique and can be selected and adjusted according to the size of the cutter head 32.

[0032] Designing the protective cover body 8 as a main protective cover 81 and a secondary protective cover 82 improves the ease of use of the protective cover body 8, making it convenient for construction personnel to handle. The roller design allows it to move on the ground when the vehicle 1 moves forward, providing auxiliary support. The flexible connection layer is made of wear-resistant materials, such as polyester fiber or polyurethane rubber. The front of the secondary protective cover 82 is also equipped with a front shield to prevent dust or impurities from falling into the front of the un-shoveled ground and affecting subsequent construction.

[0033] Example 3: Please refer to Figures 11-17 The present invention provides a technical solution: A high-frequency vibration scraping device includes a rotating seat 17 on the main guard 81 and a rotating seat 28 on the auxiliary guard 82. The rotating seats 17 and 28 have fixing holes through which insertion bolts 19 pass. An adjusting nut 20 and a fixing nut 21 are threaded onto the insertion bolts 19 in sequence. The fixing nut 21 is always in a loose state. The adjusting nut 20 can be rotated to loosen or tighten it, thereby allowing the rotating seats 17 and 28 to be adjusted or fixed. A detection component 9 is provided between the main guard 81 and the auxiliary guard 82. The rotating seat 17 and rotating seat 28 can rotate by inserting bolt 19 and fixing nut 21 (not tightened). At this time, when the vehicle 1 moves, the auxiliary guard 82 and rotating seat 28 can adaptively rotate and adjust according to the ground conditions. For example, when going uphill, the auxiliary guard 82 will tilt upward, so rotating seat 218 will rotate counterclockwise relative to rotating seat 17. When going downhill, the auxiliary guard 82 will tilt downward, so rotating seat 218 will rotate clockwise relative to rotating seat 17.

[0034] The detection component 9 includes fixed plates 91 disposed on both sides of the rotating seat 17. A pressing rod 92 is slidably disposed inside each fixed plate 91. A return spring 93 is sleeved on the outside of each pressing rod 92. A blocking plate 94 is disposed on the outside of each pressing rod 92. The two ends of the return spring 93 are connected to the fixed plate 91 and the blocking plate 94 respectively. A controller 95 is disposed on the main cover 81. The controller 95 is provided with two trigger switches 96 that are in contact with the connected pressing rods 92 respectively.

[0035] When going uphill, the rotating seat 2 18 rotates counterclockwise. At this time, it will squeeze the squeezing rod 92 on the upper part of the rotating seat 1 17, causing the squeezing rod 92 to slide backward in the fixed plate 91, thereby squeezing the adjacent trigger switch 96 on the controller 95, thus reminding the construction personnel to pay attention to going uphill, and controlling the drive motor 51 through the controller 95 to rotate the swing frame 56 upward. When going downhill, the rotating seat 2 18 rotates clockwise. At this time, it will squeeze the squeezing rod 92 at the bottom of the rotating seat 1 17, causing the squeezing rod 92 to slide backward in the fixed plate 91, thereby squeezing the adjacent trigger opening on the controller 95, thus reminding the construction personnel to pay attention to going downhill, and controlling the drive motor 51 through the controller 95 to rotate the swing frame 56 upward.

[0036] Example 4: Please refer to Figures 11-17 The present invention provides a technical solution: A high-frequency vibration shovel cutting device, wherein the main guard 81 and the auxiliary guard 82 are each provided with a pipe joint 22, and a negative pressure dust suction pipe 23 is connected to the pipe joint 22, and the negative pressure dust suction pipe 23 is connected to a negative pressure device on the support frame 4; The negative pressure suction pipe 23 can be connected through the pipe connector 22. In this solution, only the main cover 81 is connected to the negative pressure suction pipe 23. The pipe connector 22 that is not connected to the negative pressure suction pipe 23 is sealed with a plug. If both the main cover 81 and the secondary cover 82 are connected to the negative pressure suction pipe 23, a T-connector is required to connect to the negative pressure equipment. This is not a common structure and will not be described in detail.

[0037] Example 5: Please refer to Figures 11-14 The present invention provides a technical solution: A high-frequency vibration shovel cutting device, wherein the tool holder 2 is provided with a sliding groove for sliding of the sliding bar 16, and locking blocks 24 are slidably arranged on both sides of the tool holder 2, and limit springs 25 are provided on the outer side of the locking blocks 24, and the top two sides of the locking blocks 24 are chamfered. To facilitate carrying the protective cover body 8, a sliding groove is provided on the tool holder 2, so that both the main protective cover 81 and the auxiliary protective cover 82 can be installed in the sliding groove via the sliding strip 16. This eliminates the need for other carriers or tools to carry the protective cover body 8. To limit the placement of the protective cover body 8, a limiting spring 25 and a locking block 24 are designed. When placing it, simply push it inward with force, and when taking it out, simply pull it outward with force. The protective cover body 8 placed on the tool holder 2 can protect the high-frequency hydraulic impact device 7 and improve the service life of the high-frequency hydraulic impact device 7.
