Description

Technical Field

[0001] This invention relates to a rubber track laying device, belonging to the field of road paving technology. Background Technology

[0002] The quality of rubber track installation directly affects user experience and lifespan. Key requirements include minimal debris on the surface, uniform rubber granule density, and a smooth, compacted surface. However, existing rubber track installation equipment suffers from several technical defects in actual operation, as follows: 1. Inability to adaptively adjust material distribution: The discharge ports of existing equipment's storage bins are mostly of fixed size or manually adjustable, and the material distribution cannot be linked to the forward speed of the laying vehicle. When the vehicle speed increases, insufficient material distribution results in sparse particle distribution; when the vehicle speed decreases, excessive material distribution causes particle accumulation, ultimately leading to uneven overall track density and affecting performance.

[0003] 2. Large differences in paving density at bends: When the paving vehicle turns, the inner and outer sides travel different distances. However, the paving mechanisms on both sides of the traditional equipment are powered synchronously, resulting in particle accumulation on the inner side of the bend and insufficient particles on the outer side. This makes it impossible to ensure the uniformity of paving in the bend area, requiring subsequent manual repairs and increasing operating costs.

[0004] In view of the shortcomings of the existing technology, there is an urgent need for an integrated rubber track laying device that integrates functions such as debris cleaning, adaptive material laying, precise leveling, and reliable resetting, so as to solve the problems of low laying efficiency, unstable quality, and high operating costs. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems of low laying efficiency, unstable quality and high operating cost of existing technologies, and to provide a rubber track laying device. To achieve the above objectives / to solve the above technical problems, the present invention is implemented using the following technical solution: A rubber running track laying device, comprising: A paving vehicle, wherein the paving vehicle is equipped with a material shovel mechanism for clearing debris from the ground in the forward direction, and the material shovel mechanism is equipped with a material receiving unit; The material spreading mechanism, located at the bottom of the spreading vehicle, is used to control the amount of rubber granules released. The leveling mechanism, located behind the material spreading mechanism, is used to simultaneously level and compact the rubber granules. The power wheel mechanism includes two independently driven drive wheels, which are connected to the sides of the paving vehicle through their respective drive shafts. A drive motor is coaxially connected to each drive shaft. The paving mechanism is connected to the drive shafts through a gear transmission mechanism. The reset linkage mechanism is connected to the movable plate of the material spreading mechanism and is used to automatically close the discharge port when the machine stops.

[0006] Optionally, the material spreading mechanism includes a material storage bin, the movable plate is movably disposed at the bottom of the material storage bin, the two ends of the movable plate are provided with connecting columns, the connecting columns are connected to one wheel of the concentric double-row wheel on the material spreading mechanism through connecting ropes, and the other wheel of the concentric double-row wheel is connected to the centrifugal disc of the gear transmission mechanism through connecting ropes.

[0007] Optionally, the gear transmission mechanism includes a driving bevel gear mounted on a drive shaft, the driving bevel gear meshing with a driven bevel gear, the driven bevel gear being fixed by a mounting plate, the driven bevel gear being coaxially mounted with a first amplifying gear, the first amplifying gear meshing with a second amplifying gear, the second amplifying gear being coaxially mounted with a third amplifying gear, the third amplifying gear meshing with a fourth amplifying gear, the centrifugal disc being coaxially mounted with the fourth amplifying gear, and the concentric double-row wheels being mounted on the mounting plate.

[0008] Optionally, the centrifuge disc includes a disc body, on which at least three movable chambers are provided at intervals. Each movable chamber is provided with a centrifuge block and a return spring. One end of the return spring is fixed to the inner side wall of the movable chamber, and the other end is connected to the centrifuge block. The centrifuge disc is provided with a central shaft hole in the middle, and the connecting rope passes through the central shaft hole and is connected to the centrifuge block.

[0009] Optionally, a release bearing is provided at the end of the centrifugal block away from the reset spring, the outer ring of the release bearing is connected to the centrifugal block, and the inner ring of the release bearing is connected to the connecting rope.

[0010] Optionally, the leveling mechanism includes a leveling motor, the output end of which is connected to a cam, the cam is connected to a connecting plate, the connecting plate is provided with a leveling spring assembly, and the bottom of the leveling spring assembly is provided with a leveling plate.

[0011] Optionally, multiple sets of connecting rods are provided between the connecting plate and the flat plate, and the leveling spring assembly is sleeved on the connecting rods.

[0012] Optionally, the reset linkage mechanism includes a first link, a second link, and a turbine spring. One end of the first link is hinged to a movable plate, and the other end is connected to the second link via a linkage shaft. The other end of the second link is fixed to the bottom of the paving vehicle. The turbine spring is sleeved on the linkage shaft and is compressed when the two links bend relative to each other. When released, it pushes the two links to unfold, thereby resetting the movable plate.

[0013] Optionally, the storage bin is provided with an installation frame.

[0014] Optionally, the receiving unit includes a bucket, a receiving chamber, a receiving box, and a retaining frame. The bucket is located at the front end of the paving vehicle. One end of the receiving chamber connects to the tipping outlet of the bucket, and the other end connects to the receiving box. The retaining frame surrounds the upper part of the receiving chamber.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. Efficient and clean debris removal ensures the quality of the foundation material; The material shoveling mechanism is integrated with the paving vehicle, and the bucket shovels up debris synchronously with the vehicle's movement, eliminating the need for a separate cleaning process and greatly improving operational efficiency. When the bucket tilts and tipes, debris flows into the detachable receiving box through the receiving chamber groove. Combined with the interception function of the baffle frame, debris is completely prevented from splashing, ensuring a clean working area and reducing the amount of secondary cleaning work. The detachable design of the receiving box facilitates quick cleaning of collected debris, ensuring continuous operation.

[0016] 2. The amount of material applied is adaptively adjusted to ensure uniform density throughout the entire area; By utilizing the linkage design of the centrifugal disc and the power wheel mechanism, the forward speed of the paving vehicle is directly related to the opening of the discharge port: the faster the vehicle speed, the higher the rotation speed of the centrifugal disc, the greater the displacement of the centrifugal block, the larger the opening of the discharge port, and the faster the rubber particles are scattered; the opposite is true when the vehicle speed is slowed down, which fundamentally ensures the consistency of the paving density at different vehicle speeds without the need for manual intervention.

[0017] It adopts two independent power wheel mechanisms, and the speed of the drive shafts on both sides is different when turning (slower on the inner side and faster on the outer side). This drives the centrifugal discs on the corresponding sides to generate different centrifugal forces, so that the outlet of the storage bin has an approximately fan-shaped opening. This ensures that the amount of rubber particles spilled on the inner and outer sides of the curve matches the travel distance, and completely solves the problem of uneven density at the turning point.

[0018] 3. Leveling and compaction are carried out simultaneously and efficiently, improving the quality of the paved surface; The leveling mechanism and the material spreading mechanism work synchronously. After the rubber granules are scattered on the ground, the leveling motor drives the cam to rotate at high speed. In conjunction with the leveling spring assembly, the plate is lifted and lowered at high frequency, which instantly compacts the rubber granules and improves the adhesion of the granules and the flatness of the surface. The leveling spring assembly provides stable elastic pressure, ensuring uniform force on the leveling plate and preventing insufficient or excessive compaction in certain areas. This ensures the consistency of the runway surface and eliminates the need for subsequent secondary leveling, simplifying the operation process. Attached Figure Description

Connecting column 304: A columnar structure vertically fixed to the bottom of the movable plate 303, serving as the connecting fulcrum for the pull rope, transmitting the power of the concentric double-row wheels 305 to the movable plate 303, causing it to slide. Concentric double-row wheel 305: A combination of two wheels of different sizes fixed on the same axis. The smaller wheel is used to wind the pull rope connected to the centrifugal block 3074, and the larger wheel is used to wind the pull rope connected to the movable plate 303.

[0037] like Figure 9 As shown, the release bearing 3076 is located at one end of the centrifugal block 3074. The outer ring is connected to the centrifugal block 3074, and the inner ring is connected to the pull rope. It is used to release the amount of twisting of the pull rope during the rotation of the centrifugal disc 307, so as to prevent the pull rope from being twisted continuously.

[0038] Driven bevel gear 308: A bevel gear fixed coaxially with centrifugal disc 307. It receives power by meshing with driving bevel gear 309, converting the horizontal rotation of drive shaft 502 into the vertical rotation of centrifugal disc 307.

[0045] Connecting rod 403: A rigid connecting component, one end of which is fixed to the leveling plate 402, and the other end is connected to the plate 404, transmitting the elastic force of the leveling spring assembly 401 and the lifting force of the cam 406.

[0046] Connecting plate 404: an intermediate transition component used to connect multiple connecting rods 403, so that the entire plate 402 is subjected to uniform force, and at the same time cooperates with cam 406 to achieve intermittent lifting.

[0047] Leveling motor 405: The power source of the leveling mechanism 4, fixed to the bottom of the paving vehicle 1, drives the cam 406 to rotate at high speed, providing power for the leveling action.

[0048] Cam 406: Eccentric wheel structure, fixed to the output shaft of leveling motor 405. When rotating, it intermittently lifts connecting plate 404, and works with leveling spring assembly 401 to realize the up-and-down reciprocating motion of leveling plate 402.

[0049] like Figure 8 As shown, the reset linkage mechanism 6 includes a first link 601, a second link 603, and a turbine spring 604.

[0053] Turbine spring 604: An elastic component sleeved on the linkage shaft 602. It is compressed when the two connecting rods are bent relative to each other, and when released, it pushes the two connecting rods to unfold, thereby driving the movable plate 303 to reset.

[0054] like Figure 2 As shown, the material shoveling mechanism 2 includes a bucket 201, a receiving chamber 202, a receiving box 203, and a retaining frame 204. The bucket 201 is located at the front end of the paving vehicle 1. One end of the receiving chamber 202 is connected to the tipping outlet of the bucket 201, and the other end is connected to the receiving box 203. The retaining frame 204 surrounds the upper part of the receiving chamber 202.

[0055] Bucket 201: The front end is a wedge-shaped digging component made of hard and wear-resistant material. In the initial state, it is flat and in contact with the ground. As the paving vehicle 1 moves forward, it digs up gravel, fallen leaves and other debris. It can be tilted upwards and dumped under the drive of the tipping motor.

[0056] Material receiving chamber 202: An inclined material guiding channel, one end of which connects to the tipping outlet of the bucket 201, and the other end connects to the material receiving box 203, guiding the dumped debris to flow in a directional manner and preventing it from scattering.

[0057] Receiving box 203: A detachable storage component used to collect debris conveyed by the receiving chamber 202. It can be quickly disassembled and cleaned when the box is full, ensuring continuous operation.

[0058] Material stop frame 204: A protective structure surrounding the outlet of the receiving cavity 202. Its height is higher than the edge of the cavity to prevent debris from splashing when it is poured, thus avoiding contamination of the working environment or affecting the accuracy of subsequent material laying.

[0059] Working principle, 1. Start-up and preliminary preparation: After the paving vehicle starts, the drive motor 501 starts working, driving the drive shaft 502 to rotate, which in turn drives the drive wheel 503 to rotate, providing forward power for the paving vehicle. At this time, all mechanisms are in the initial state: the bucket 201 is leveled and in contact with the ground, the movable plate 303 blocks the outlet of the storage box 301 under the action of the reset linkage mechanism 6, the leveling motor 405 is on standby, and the leveling plate 402 lightly touches the ground or is in the position to be compacted under the action of the leveling spring group 401.

[0060] 2. Debris removal and shoveling operations: As the paving vehicle moves forward, the bucket 201 rubs against the ground, scooping up debris such as gravel and fallen leaves that could affect the quality of the paving. At preset intervals, based on the amount of debris accumulated, the tipping motor (not shown) starts, driving the bucket 201 to tilt upwards. The debris inside is then dumped by gravity into the receiving chamber 202, and guided into the receiving box 203. The retaining frame 204 effectively intercepts splashed debris, preventing contamination of the work area. After dumping is complete, the bucket 201 tilts back to its original position. During this process, the paving vehicle pauses to ensure complete removal of debris before continuing to shovel material.

[0061] 3. Material laying power transmission and outlet opening: As the paving vehicle moves forward, the drive shaft 502 drives the active bevel gear 309 on the shaft to rotate. The active bevel gear 309 meshes with the driven bevel gear 308, transmitting power to the driven bevel gear 308, which in turn drives the centrifugal disc 307, which is fixed coaxially with it, to rotate synchronously. The mounting plate 306 provides stable support for the transmission group.

[0062] When the centrifugal disc 307 rotates, the three centrifugal blocks 3074 inside move along their respective movable chambers 3072 towards the outer periphery of the disc body 3071 under the action of centrifugal force, compressing the return spring 3073. A pull rope connected to one of the centrifugal blocks 3074 extends through the central shaft hole 3075 to the bottom of the paving vehicle and is wound around the small wheel of the concentric double-row wheel 305. When the centrifugal block 3074 moves outward, it pulls the pull rope, causing the small wheel to rotate; since the large wheel of the concentric double-row wheel 305 is coaxially fixed with the small wheel, the large wheel rotates synchronously and winds up the pull rope wound on its surface. The pull rope pulls the movable plate 303 through the connecting column 304, causing the movable plate 303 to slide along the mounting frame 302 towards the power wheel mechanism 5. The outlet of the storage bin 301 is gradually opened, and the internal rubber particles fall to the ground under the action of gravity.

[0063] At the same time, when the movable plate 303 slides, it drives the first link 601 of the reset linkage mechanism 6 to move, so that the first link 601 and the second link 603 are bent relative to each other through the linkage shaft 602, compressing the turbine spring 604 and storing elastic potential energy for subsequent reset.

[0064] 4. Core advantage of adaptive material distribution adjustment: (1) Adjustment of material quantity based on vehicle speed: The forward speed of the paving vehicle is controlled by the rotation speed of the drive motor 501: the faster the vehicle speed, the higher the rotation speed of the drive shaft 502, the faster the transmission speed of the active bevel gear 309 and the driven bevel gear 308, the higher the rotation speed of the centrifugal disc 307, the greater the centrifugal force on the centrifugal block 3074, the farther the distance moved along the movable cavity 3072, and the longer the length of the pulling rope. This series of chain reactions leads to an increase in the rotation angle of the concentric double-row wheel 305, a longer sliding distance of the movable plate 303, a larger opening of the outlet of the storage box hopper 301, and a synchronous increase in the speed and total amount of rubber granules falling; conversely, the slower the vehicle speed, the smaller the centrifugal force, the smaller the opening of the outlet, and the less the amount of granules falling, ultimately achieving consistency in the density of rubber granules at different vehicle speeds; (2) Adjustment of material distribution based on turning: Since the power wheel mechanism 5 is set up independently on both sides of the vehicle, the inner drive wheel 503 rotates slowly and has a small turning radius when turning, while the outer drive wheel 503 rotates quickly and has a large turning radius. The rotation speeds of the corresponding active bevel gear 309, driven bevel gear 308, and centrifugal disc 307 on both sides will differ accordingly: the inner centrifugal disc 307 rotates at a low speed, the centrifugal block 3074 moves a short distance, the corresponding movable plate 303 slides a short distance, and the outlet opening is small; the outer centrifugal disc 307 rotates at a high speed, the centrifugal block 3074 moves a long distance, the corresponding movable plate 303 slides a long distance, and the outlet opening is large. Finally, the outlet of the storage bin 301 presents an approximately fan-shaped opening state, ensuring that the density of rubber particles distributed on both sides of the curve is uniform and avoiding the problem of accumulation on the inner side and sparse distribution on the outer side.

[0065] 5. Leveling and compaction operations: As rubber granules are scattered onto the ground, the leveling motor 405 starts, driving the cam 406 to rotate at high speed. During the rotation, the cam 406 intermittently contacts the connecting plate 404, lifting the connecting plate 404 upwards. This, in turn, causes the leveling plate 402 to move upwards via the connecting rod 403, while simultaneously compressing the leveling spring assembly 401. When the cam 406 rotates away from the connecting plate 404, the leveling spring assembly 401 releases its elastic potential energy, pushing the connecting plate 404 downwards rapidly. This causes the leveling plate 402 to press instantly against the ground, leveling and compacting the scattered rubber granules. This ensures that the track surface is flat and the compaction meets design requirements. This action is repeated continuously, achieving simultaneous "material laying and leveling".

[0066] 6. When the mechanism resets and stops operation: When the paving vehicle completes its work or needs to pause, the drive motor 501 stops working, the drive shaft 502 and the centrifugal disc 307 stop rotating, and the centrifugal force disappears. The centrifugal block 3074 resets along the movable cavity 3072 under the elastic force of the return spring 3073, and the pull rope loosens. Simultaneously, the compressed turbine spring 604 in the reset linkage mechanism 6 releases its elastic pressure, pushing the first link 601 and the second link 603 to unfold and reset, causing the movable plate 303 to slide in the opposite direction along the mounting frame 302, returning to its initial position and re-sealing the outlet of the storage hopper 301, stopping the spillage of rubber particles. The leveling motor 405 stops working, the leveling plate 402 resets, completing one work cycle.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
