Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to an asphalt paver, particularly an asphalt paver for concrete core wall construction. Background Technology

[0002] An asphalt concrete core wall is a central seepage barrier in an earth-rock dam made of asphalt concrete. In engineering projects, dense asphalt concrete core walls are often used, constructed in layers. During construction, a formwork recessed below the dam surface or ground level is first erected, then concrete is poured into the formwork groove, followed by asphalt pouring on top of the concrete layer.

[0003] After the concrete layer is poured, a large amount of construction waste such as gravel and concrete blocks remains on top of it. This waste needs to be cleaned before the paver can work. Larger pieces of construction waste are carried away by workers, but smaller pieces of gravel and stones are numerous and widely distributed. Workers need to sweep these small pieces into a dustpan with brooms and then pour them out of the formwork trough. This is not only inefficient but also labor-intensive. Although some pavers have cleaning functions, they are only suitable for flat ground and cannot effectively remove construction waste from the trough. Furthermore, because the asphalt is not compacted after paving, the density of the asphalt layer is uneven and its firmness is insufficient, which directly affects the service life of the asphalt layer. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an asphalt paver for concrete core wall construction. This asphalt paver is capable of cleaning small construction wastes within the formwork groove, which is not only highly efficient but also allows for the collection of the cleaned construction wastes for centralized processing.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An asphalt paver for concrete core wall construction includes a paver body, a paving hopper, paver tracks, and a screeding device, and further includes:

[0007] A tamping assembly used to compact asphalt;

[0008] A long track is set on one side of the paver body, with side plates bolted to both sides of the track and a ramp bolted to the head end of the track.

[0009] An active roller is rotatably connected between the side plates on both sides, and a driven roller is also rotatably connected between the side plates on both sides;

[0010] Several auxiliary rollers are rotatably connected between the two side plates;

[0011] A conveyor belt is provided on the surfaces of a drive roller, a driven roller, and an auxiliary roller, wherein the drive roller, the driven roller, and the auxiliary roller are all in rolling contact with the inner surface of the conveyor belt;

[0012] Several scrapers fixed to the surface of the conveyor belt;

[0013] A support frame bolted to one side of the side plate, with a drive motor for powering the drive roller bolted to the top of the support frame;

[0014] A hopper is connected to the bottom of the long channel, and discharge pipes are connected to both sides of the bottom of the hopper;

[0015] Collection boxes are set on both sides of the paver body, and the other end of the hopper extends to the top of the collection box;

[0016] A shaking assembly used to make the collection box shake up and down;

[0017] A lifting assembly used to control the height of a long track.

[0018] The working principle of this invention is as follows: The hydraulic rod is activated, causing its output shaft to retract and lower the side plate and long track into the template groove. The drive motor is activated, driving the active roller to rotate. Then, the conveyor belt begins to move, and the scraper on the surface of the conveyor belt follows the movement. After the scraper moves to the bottom, it pushes small construction waste materials to move. The scraper moves in the direction of the conveyor belt and pushes the construction waste materials through the ramp and long track into the discharge hopper. The waste materials entering the discharge hopper enter the collection box through the discharge pipe, realizing the collection and processing of construction waste materials. Through the contact between the paver track and the rubber rollers, the platform moves up and down, shaking the waste materials entering the collection box. The asphalt falling from the paving hopper enters the template groove. The subsequent screeding device performs the asphalt paving operation. Moreover, the traveling wheels drive the transmission rod and drive rod to rotate, causing the movable column and pressure plate to move up and down reciprocally, compacting the laid asphalt.

[0019] The tamping assembly includes a traveling wheel, a lower plate, a support plate, and a transmission rod. The lower plate is bolted to the underside of the surface of the ironing device. The traveling wheel is rotatably connected to the surface of the lower plate. The support plate is bolted to the top of the ironing device. The transmission rod is rotatably connected to the support plate, and the transmission rod is connected to the rotating shaft of the traveling wheel via a belt drive. The tamping assembly also includes a support plate and a connecting column bolted to the other side of the top of the ironing device. A drive rod is rotatably connected to the surface of the support plate, and the transmission rod is connected to the drive rod via a belt drive. Both sides of the surface of the drive rod are rotatably connected to a connecting rod. A movable sleeve is welded to the other end of the connecting column. A movable column is slidably arranged on the inner wall of the movable sleeve. A connecting piece that is hinged to the connecting rod is bolted to the top of the movable column, and a pressure plate is bolted to the bottom of the movable column.

[0020] The above structure enables the compaction of asphalt, improving the firmness of asphalt paving and ensuring the effectiveness of asphalt paving.

[0021] The lifting assembly includes a hydraulic rod and a vertical frame bolted to the top of the paver body. A slider is slidably connected to the inner wall of the vertical frame. Vertical strips are also bolted to both sides of the inner wall of the vertical frame, and the slider is slidably connected to the surface of the vertical strips. A fixed column is bolted to one side of the slider, and the other end of the fixed column is bolted to the side plate.

[0022] The above structure allows for adjustment of the vertical height of the side panels and the track.

[0023] The vertical height of the inner wall of the vertical frame is greater than the maximum extension range of the hydraulic rod.

[0024] The above structure is used to prevent the slider from being restricted by the vertical frame.

[0025] The material shaking assembly includes a platform, a sliding sleeve, and a sliding rod. The sliding rod is bolted to the top of the paver body, the sliding sleeve is bolted to one side of the platform and slidably connected to the surface of the sliding rod, and a rubber roller is bolted to the bottom of the platform, and the rubber roller is in rolling contact with the surface of the paver track.

[0026] The above structure prevents waste from accumulating in the collection bin and easily overflowing.

[0027] The top of the shelf is also fixed with a magnet.

[0028] The above structure is used to adsorb and fix the collection box.

[0029] The shaft of the drive roller extends to the outside of the side plate, and the output shaft of the drive motor is connected to the shaft of the drive roller through gear transmission.

[0030] The above structure is used to provide power to the drive roller.

[0031] The two ends of the long track are designed to be flush, and the middle section of the long track is designed to be inclined. The direction of the side plate is similar to the shape of the long track.

[0032] The above structure is used to lift the waste material.

[0033] The driven roller has the same size as the driving roller, and the auxiliary roller has a smaller size than the driving roller. The range of the auxiliary roller is similar to the direction of the side plate.

[0034] The above structure keeps the conveyor belt taut, preventing it from becoming loose.

[0035] Both the conveyor belt and the scraper are made of rubber, and the width of the scraper is the same as the width of the conveyor belt.

[0036] The above structure allows the scraper to better adapt to the surface of long tracks.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0038] 1. This invention uses a drive motor to rotate the active roller, which in turn moves the conveyor belt and scraper. The scraper pushes the construction waste in the template groove through the ramp and long channel into the discharge hopper, thus cleaning the construction waste in the template groove. This improves work efficiency and reduces workload. The cleaned construction waste then passes through the discharge hopper and discharge pipe into the collection box for centralized processing.

[0039] 2. The present invention, through the setting of the shaking component, can shake the collection box up and down, so as to avoid the waste entering the collection box being too concentrated and overflowing.

[0040] 3. The present invention, through the setting of the lifting component, can control the height of the long track and the side plate so that the long track and the side plate can enter the template groove or move out of the template groove. Attached Figure Description

A long track 8 is provided on one side of the paver body 1, with side plates 7 bolted to both sides of the track 8. A ramp 9 is bolted to the head end of the track 8. The bottom of the ramp 9 is flat, and the top of the ramp 9 is inclined. A drive roller 10 is rotatably connected between the side plates 7 on both sides, and a driven roller 11 is also rotatably connected between the side plates 7 on both sides. The drive roller 10 is positioned at a higher position, and the driven roller 11 is positioned at a lower position. Several auxiliary rollers 12 are rotatably connected between the plates 7. The surfaces of the drive roller 10, driven roller 11 and auxiliary roller 12 are provided with a conveyor belt 13. The drive roller 10, driven roller 11 and auxiliary roller 12 are all tumbled to the inner surface of the conveyor belt 13. Several scrapers 14 are fixed on the surface of the conveyor belt 13. A support frame 15 is bolted to one side of the side plate 7. A drive motor 16 is bolted to the top of the support frame 15. A hopper 17 is connected to the bottom of the long track 8. Discharge pipes 18 are connected to both sides of the bottom of the hopper 17. Collection boxes 19 are provided on both sides of the paver body 1. The other end of the hopper 17 extends to the top of the collection box 19.

[0054] The tamping assembly 5 includes a traveling wheel 51, a lower plate 52, a support plate 53, and a transmission rod 54. The lower plate 52 is bolted to the underside of the surface of the ironing device 4. The traveling wheel 51 is rotatably connected to the surface of the lower plate 52. The support plate 53 is bolted to the top of the ironing device 4. The transmission rod 54 is rotatably connected to the support plate 53, and the transmission rod 54 is connected to the shaft of the traveling wheel 51 via a belt drive. The tamping assembly 5 also includes a support plate 55 and a connecting column 59. The support plate 55 and the connecting column 59 are bolted to the other side of the top of the ironing device 4. The surface of the support plate 55... A drive rod 56 is rotatably connected to the surface of the paver, and the transmission rod 54 is connected to the drive rod 56 via a belt drive. Connecting rods 57 are rotatably connected to both sides of the surface of the drive rod 56. A movable sleeve 510 is welded to the other end of the connecting column 59. A movable column 511 is slidably disposed on the inner wall of the movable sleeve 510. A connecting piece 58 is bolted to the top of the movable column 511, and the connecting piece 58 is hinged to the connecting rod 57. A pressure plate 512 is bolted to the bottom end of the movable column 511. In this embodiment, during the movement of the paver, the scalding device 4... The asphalt is smoothed by contact with the ground, and at the same time, the two sides of the smoothing device 4 contact the ground on both sides of the core wall formwork groove. When the paver moves, the traveling wheels 51 travel along the ground and rotate. The traveling wheels 51 drive the transmission rod 54 to rotate. Then, the transmission rod 54 drives the drive rod 56 to rotate through the belt. The drive rod 56 drives one end of the connecting rod 57 to make a circular motion. The other end of the connecting rod 57 drives the movable column 511 to move up and down through the connector 58, which makes the movable column 511 slide up and down along the inner wall of the movable sleeve 510. The moving column 511 drives the pressure plate 512 to move up and down reciprocally to compact the asphalt, thereby achieving the vibration compaction operation of the asphalt, improving the firmness of the asphalt paving, ensuring the asphalt paving effect, and also causing the traveling wheels 51 to rotate during the movement of the paver, providing power for the up and down movement of the pressure plate 512 to perform the vibration compaction operation, eliminating the need for an additional power source and reducing the energy consumption of the paver; the screeding device 4 consists of a screeding heating device and a screeding plate. The screeding device 4 is existing technology, and its detailed structure and working method will not be described in detail.

[0055] The lifting assembly 6 includes a hydraulic rod 61 and a vertical frame 62. The hydraulic rod 61 and the vertical frame 62 are bolted to the top of the paver body 1. A slider 64 is slidably connected to the inner wall of the vertical frame 62. Vertical bars 63 are also bolted to both sides of the inner wall of the vertical frame 62, and the slider 64 is slidably connected to the surface of the vertical bars 63. A fixing column 65 is bolted to one side of the slider 64, and the other end of the fixing column 65 is bolted to the side plate 7. In this embodiment, by opening the hydraulic rod 61, its output shaft extends, which can drive the slider 64 to move in the vertical direction. The slider 64 moves up and down, and through the connecting column 59, it drives the side plate 7 and the long track 8 to move in the vertical direction, thereby achieving the effect of adjusting the vertical height of the side plate 7 and the long track 8.

[0056] The vertical height of the inner wall of the vertical frame 62 is greater than the maximum extension range of the hydraulic rod 61. In this embodiment, since the vertical movement range of the slider 64 depends on the extension range of the output shaft of the hydraulic rod 61, the vertical height of the inner wall of the vertical frame 62 is limited to prevent the slider 64 from being restricted by the vertical frame 62.

[0057] The material shaking assembly 20 includes a platform 201, a sliding sleeve 202, and a sliding rod 203. The sliding rod 203 is bolted to the top of the paver body 1. The sliding sleeve 202 is bolted to one side of the platform 201 and slidably connected to the surface of the sliding rod 203. A rubber roller 204 is also bolted to the bottom of the platform 201, and the rubber roller 204 is in rolling contact with the surface of the paver track 3. In this embodiment, the collection box 19 is placed on the surface of the platform 201 during use, and the crushed stone discharged from the discharge pipe 18... Once the construction waste enters the collection bin 19, the paver body 1 moves along its tracks. The paver tracks 3 contact the rubber rollers 204, causing the rubber rollers 204 to drive the platform 201 to shake up and down. The platform 201 can move up and down along the surface of the slide bar 203 via the sliding sleeve 202, ensuring that the platform 201 can only move up and down. The platform 201 shakes the waste in the collection bin 19, preventing the waste that falls into the collection bin 19 from accumulating together and easily overflowing.

[0058] A magnet 205 is also fixed on the top of the shelf 201. In this embodiment, the collection box 19 is made of metal, and the magnet 205 on the top of the shelf 201 can attract and fix the collection box 19.

[0059] The shaft of the drive roller 10 extends to the outside of the side plate 7, and the output shaft of the drive motor 16 is connected to the shaft of the drive roller 10 through gear transmission. In this embodiment, by setting the drive motor 16, when the drive motor 16 is turned on, its output shaft can drive the shaft of the drive roller 10 to rotate through the gear, thereby providing power to the drive roller 10.

[0060] The two ends of the long channel 8 are designed to be flush, and the middle section of the long channel 8 is designed to be inclined. The direction of the side plate 7 is similar to the shape of the long channel 8. In this embodiment, the scraper 14 pushes the construction waste in the template groove into the long channel 8, and transports it to the top through the inclined part of the long channel 8, so as to achieve the effect of lifting the waste.

[0061] The driven roller 11 has the same size as the driving roller 10, and the auxiliary roller 12 has a smaller size than the driving roller 10. The range of the auxiliary roller 12 is similar to the direction of the side plate 7. In this embodiment, through the design of several auxiliary rollers 12, the conveyor belt 13 can be supported, so that the conveyor belt 13 is in a taut state and the conveyor belt 13 is prevented from becoming loose.

[0062] Both the conveyor belt 13 and the scraper 14 are made of rubber, and the width of the scraper 14 is the same as the width of the conveyor belt 13. In this embodiment, both the rubber conveyor belt 13 and the scraper 14 are elastic, which allows the scraper 14 to better adapt to the surface of the long track 8.

[0063] The working principle of this invention is as follows: After concrete is poured and solidified inside the wall formwork, the paver body 1 is first driven to the top of the concrete core wall formwork, with the paver tracks 3 positioned on both sides of the formwork. Then, the hydraulic rod 61 is activated to retract its output shaft, causing the slider 64 and fixed column 65 to descend, and the side plate 7 and long track 8 to descend, so that the bottom surface of the slope 9 near the head end of the long track 8 is in contact with the bottom surface of the formwork groove. At this time, the scraper 14 located near the driven roller 11 is also in contact with the bottom surface of the formwork groove. The drive motor 16 is then activated, and its output shaft drives the drive roller 10 clockwise via gears. The conveyor belt 13 begins to rotate, driving the auxiliary roller 12 and driven roller 11 to rotate as well. The scraper 14 on the surface of the conveyor belt 13 also moves accordingly. After the scraper 14 moves downwards, it moves towards the long track 8, while the paver is in a forward-moving state. The scraper 14 contacts small gravel, small concrete blocks, and other small construction waste in the formwork groove, pushing these construction wastes forward. The scraper 14 moves in the direction of the conveyor belt 13, pushing the construction waste from the surface of the ramp 9 into the long track 8, and then the construction waste moves with the scraper 14. The waste material is discharged above the long track 8 and then falls into the hopper 17, cleaning the concrete core wall formwork groove without requiring workers to use brooms and dustpans, thus improving the efficiency of the cleaning operation. The waste material entering the hopper 17 enters the collection box 19 through the discharge pipe 18, also collecting and processing construction waste. At the same time, during the movement of the paver, the paver track 3 contacts the rubber rollers 204, causing the platform 201 to move up and down, shaking the waste material entering the collection box 19 to prevent the waste material from accumulating and easily overflowing. After the collection box 19 is full, the paver temporarily stops, and the workers... The operator removes the full collection box 19 and replaces it with an empty one. During the paver's movement, the asphalt falling from the paving hopper 2 enters the template groove, and the subsequent screeding device 4 performs the asphalt paving operation. The traveling wheels 51 move along the ground and drive the transmission rod 54 and drive rod 56 to rotate, causing the movable column 511 and pressure plate 512 to move up and down to compact the paved asphalt. After the asphalt in the paving hopper 2 is used up, the side plate 7 and the long track 8 are raised, and the paver reverses to compact and screed the previously paved asphalt again, thereby improving the asphalt's firmness.

[0064] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
