Description

Technical Field

[0001] This utility model relates to the technical field of asphalt mixture compaction equipment, and in particular to a low-temperature warm-mix asphalt mixture rapid compaction equipment. Background Technology

[0002] In asphalt pavement construction, compaction is a crucial step in ensuring pavement density, durability, and performance. Traditional hot-mix asphalt mixtures require compaction at high temperatures (typically 150–180°C), resulting in high energy consumption and significant pollution. Low-temperature warm-mix asphalt mixtures, through the addition of warm-mix agents or foaming technology, lower the construction temperature to 100–130°C, reducing carbon emissions and fuel consumption, and aligning more closely with green construction trends. When laying low-temperature warm-mix asphalt mixtures, compaction is required using road rollers. Road rollers used in asphalt pavement construction include static rollers, pneumatic tire rollers, and vibratory rollers. Vibratory rollers are relatively more efficient; compared to static rollers and pneumatic tire rollers, they require significantly fewer compaction passes to achieve the same compaction degree, enabling faster completion of the compaction work and shortening the project cycle.

[0003] Currently, to enhance compaction efficiency, scrapers are installed near the steel wheel of vibratory rollers to promptly remove asphalt, mud, and other impurities adhering to the wheel surface, preventing any impact on compaction quality and efficiency. However, scrapers are prone to wear under continuous scraping conditions, requiring frequent replacement to maintain normal function. Currently, vibratory roller scrapers are mostly installed using a large number of bolts for fastening. During replacement, operators must use tools to disassemble each bolt individually. This method of fixing is not only physically demanding but also significantly increases equipment downtime for maintenance, reducing overall construction efficiency. Utility Model Content

[0004] This utility model relates to a rapid compaction device for low-temperature warm-mix asphalt mixtures. It uses a rapid limiting component to quickly insert and limit the scraper, so that when the scraper is severely worn and needs to be replaced, the operator does not need to use tools to disassemble the bolts one by one. This not only saves physical labor, but also effectively reduces equipment downtime for maintenance and significantly improves overall construction efficiency.

[0005] In a first aspect, this utility model provides a rapid compaction device for low-temperature warm-mix asphalt mixtures, specifically comprising: a vibratory roller body, on which a scraper mounting seat is fixedly installed; a groove is provided on the scraper mounting seat, and a scraper is slidably connected inside the groove; a quick-limiting component is installed on the lower part of the front end face of the scraper mounting seat, and an L-shaped snap-on support plate is fixedly installed on the upper part of the front end face of the scraper mounting seat; and a limiting through hole is provided on the front end face of the scraper.

[0006] Furthermore, strip-shaped sliders are provided on the upper part of both the front and rear ends of the scraper, and the strip-shaped sliders are slidably connected to the groove.

[0007] Furthermore, the number of limiting through holes is four, and the four limiting through holes are evenly distributed on the scraper.

[0008] Furthermore, the quick-stop assembly includes four rectangular slide cylinders, which are uniformly and fixedly installed on the lower part of the front end face of the scraper mounting seat. Each rectangular slide cylinder has a rectangular slider slidably connected inside it. Each rectangular slider has a limiting rod fixedly connected to its rear end face, penetrating the rear side wall of the rectangular slide cylinder. Each rectangular slider has a pulling rod fixedly connected to its front end face, penetrating the front side wall of the rectangular slide cylinder. Each pulling rod has a spring sleeved on its exterior inside the rectangular slide cylinder. The front ends of the four pulling rods are fixedly connected to a synchronous pull rod, and the front end face of the synchronous pull rod has a handle in the middle.

[0009] Furthermore, a snap-fit ​​plate is fixedly connected to the middle of the upper end face of the synchronous pull rod, and a strip-shaped snap-fit ​​opening is provided on the front end face of the snap-fit ​​plate.

[0010] Furthermore, when the scraper is fixed inside the scraper mounting seat, the four limiting rods are respectively inserted into the four limiting through holes.

[0011] Furthermore, the lower part of the front end face of the L-shaped buckle support plate has two rectangular openings that are symmetrically arranged on the left and right sides, and each rectangular opening is slidably connected to an elastic buckle, and each rectangular opening is equipped with a spring; a reinforcing plate is fixedly connected to both the left and right sides of the L-shaped buckle support plate.

[0012] This utility model provides a rapid compaction device for low-temperature warm-mix asphalt mixtures, which has the following beneficial effects:

[0013] 1. This utility model slidably connects the scraper to the inside of the scraper mounting base, and then uses a quick-connect limiting component to quickly insert and limit the scraper. Therefore, when the scraper is severely worn and needs to be replaced, simply pull the synchronous pull rod forward manually, pulling it out from the four limiting through holes along with the four limiting rods. Then, slide the scraper to the left or right to remove and replace it. Thus, during the replacement process, the operator does not need to use tools to disassemble the bolts one by one, which not only saves physical labor but also effectively reduces equipment downtime for maintenance and significantly improves overall construction efficiency.

[0014] 2. This utility model, through the cooperation of an L-shaped buckle support plate, a rectangular opening, elastic buckles, a snap-fit ​​plate, and a strip-shaped snap-fit, enables the two elastic buckles to engage with the strip-shaped snap-fit ​​when the synchronous pull rod moves forward to its limit position. Through the snap-fit ​​action of the elastic buckles and the strip-shaped snap-fit, the forward-moving synchronous pull rod can be effectively limited. Thus, when disassembling the scraper, it is not necessary to keep pulling the synchronous pull rod forward by hand, which significantly optimizes the operation process and greatly improves the convenience and efficiency of quick scraper replacement.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1: Please refer to Figures 1 to 5 :

[0030] This utility model proposes a rapid compaction device for low-temperature warm-mix asphalt mixture, comprising: a vibratory roller body 1, on which a scraper mounting seat 2 is fixedly installed; a groove 201 is provided on the scraper mounting seat 2, and a scraper 3 is slidably connected inside the groove 201; a rapid limiting component 4 is installed on the lower part of the front end face of the scraper mounting seat 2, and an L-shaped buckle support plate 5 is fixedly installed on the upper part of the front end face of the scraper mounting seat 2; a limiting through hole 302 is provided on the front end face of the scraper 3 for insertion with a limiting rod 403.

[0031] The upper part of both the front and rear ends of the scraper 3 is provided with strip sliders 301, and the strip sliders 301 are slidably connected to the grooves 201; there are four limiting through holes 302, and the four limiting through holes 302 are evenly distributed on the scraper 3.

[0032] The quick-stop component 4 includes four rectangular slide cylinders 401, which are uniformly fixedly installed on the lower front face of the scraper mounting seat 2. Each rectangular slide cylinder 401 has a rectangular slider 402 slidably connected inside. Each rectangular slider 402 has a limiting rod 403 fixedly connected to its rear end face, penetrating the rear side wall of the rectangular slide cylinder 401. Each rectangular slider 402 has a pulling rod 404 fixedly connected to its front end face, penetrating the front side wall of the rectangular slide cylinder 401. Each pulling rod 404 is fitted with a spring inside the rectangular slide cylinder 401. The front ends of the four pulling rods 404 are fixedly connected to a synchronous pull rod 405, and the front end face of the synchronous pull rod 405 has a handle in the middle. The quick-stop component 4 is used to quickly limit the scraper 3.

[0033] When the scraper 3 is fixed inside the scraper mounting base 2, the four limiting rods 403 are respectively inserted into the four limiting through holes 302, and the scraper 3 is quickly and effectively limited inside the scraper mounting base 2.

[0034] Example 2, based on Example 1, such as Figures 2 to 5As shown, a snap-fit ​​plate 406 is fixedly connected to the middle of the upper end face of the synchronous tie rod 405, and a strip-shaped snap-fit ​​opening 407 is provided on the front end face of the snap-fit ​​plate 406; two rectangular openings 501 are symmetrically provided on the lower part of the front end face of the L-shaped snap-fit ​​support plate 5, and an elastic snap 502 is slidably connected inside each rectangular opening 501, and a spring is installed inside each rectangular opening 501; a reinforcing plate 503 is fixedly connected to both the left and right sides of the L-shaped snap-fit ​​support plate 5; through the L-shaped snap-fit ​​support plate 5 and the rectangular openings The cooperation of 501, elastic buckle 502, snap-fit ​​plate 406 and strip-shaped bayonet 407 allows the two elastic buckles 502 to engage with the strip-shaped bayonet 407 after the synchronous pull rod 405 moves forward to its limit position. Through the engagement of the elastic buckles 502 and the strip-shaped bayonet 407, the forward-moving synchronous pull rod 405 can be effectively limited. Therefore, when disassembling the scraper 3, it is not necessary to keep pulling the synchronous pull rod 405 forward by hand, which further improves the convenience of disassembling and replacing the scraper 3.

[0035] The working principle of this embodiment is as follows: When compacting the low-temperature warm-mix asphalt mixture for road surface paving, the vibratory roller body 1 rapidly compacts the low-temperature warm-mix asphalt mixture. During the compaction process, the scraper 3 removes asphalt, mud, and other impurities adhering to the surface of the steel wheel on the vibratory roller body 1, thereby improving the compaction effect and efficiency.

[0036] When the scraper 3 is severely worn and needs to be replaced, simply pull the synchronous pull rod 405 forward manually. This will move the four pull rods 404, the four rectangular sliders 402, and the four limit rods 403 forward simultaneously, causing the four limit rods 403 to be pulled out from the four limit through holes 302. At this point, the scraper 3 loses its fixing function inside the scraper mounting seat 2. Then, the scraper 3 can be slid to the left or right to remove and replace it. Thus, during the replacement process, the operator does not need to use tools to remove the bolts one by one, which not only saves physical strength but also effectively reduces the equipment downtime for maintenance.

[0037] When the synchronous pull rod 405 moves forward to its limit position, the front end of the snap-fit ​​plate 406 contacts the lower rear side of the L-shaped snap-fit ​​support plate 5, and at this time, the two elastic snaps 502 engage with the strip-shaped snap-fit ​​407. Through the engagement of the elastic snaps 502 and the strip-shaped snap-fit ​​407, the forward-moving synchronous pull rod 405 can be effectively limited, so that when disassembling the scraper 3, it is not necessary to keep pulling the synchronous pull rod 405 forward by hand, thus further improving the convenience of disassembling and replacing the scraper 3. After the new scraper 3 is installed inside the scraper mounting seat 2, the two elastic snaps 502 are pinched in opposite directions at the same time to separate the two elastic snaps 502 from the strip-shaped snap-fit ​​407. Then, the synchronous pull rod 405 loses its limiting effect, and finally the four limiting inserts 403 are inserted into the four limiting through holes 302, realizing the quick replacement operation of the scraper 3.
