Abstract
Description
Technical Field
[0001] This invention relates to the field of municipal equipment technology, specifically to a hot-mix asphalt paving equipment. Background Technology
[0002] Asphalt is a complex, dark brown mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid widely used for road paving, such as... Figure 9 As shown, when the road surface around the manhole cover is damaged, workers need to first cut the asphalt road surface in the damaged area around the manhole cover along a square structure, then clean the cut road surface, and then lay new asphalt mixture in the cut area.
[0003] Existing technologies also provide technical solutions for asphalt recycling and separation. For example, Chinese invention patent with publication number CN108867290A discloses an asphalt paving device for road engineering. First, the asphalt is mixed and fed through a mixing drum and a conveying drum to avoid asphalt sticking and ensure smooth construction. Then, the asphalt is efficiently paved by a paving plate and a compaction roller connected to a reciprocating motion mechanism.
[0004] However, the above patent application has the following shortcomings: 1. Since a manhole cover is installed at the center of the cutting area, when the paving equipment is pushed to move in the cutting area, the manhole cover will obstruct the wheels, thus preventing the paving of the edge area of the manhole cover. In addition, the internal space of the square cutting area is narrow, which makes it inconvenient for the paving equipment to move in the cutting area.
[0005] 2. Due to the lack of cleaning equipment, the paving equipment will spill asphalt onto the original road surface outside the cutting area during the asphalt laying process. After the asphalt is laid, the staff will need to clean up the asphalt on the original road surface again, which increases the number of steps for the staff. Summary of the Invention
[0006] This invention provides a hot-mix asphalt paving device to solve the problems in related technologies, such as the inconvenience of paving equipment in cutting areas, the inability to fully pave the edge areas of manhole covers, and the need for workers to clean the asphalt on the original road surface again due to the lack of outer edge cleaning.

[0011] In one embodiment, the scraping assembly includes a second outer cover. A first extension rod is installed on the left side of the lower horizontal section of the support frame. The second outer cover is installed at the left end of the first extension rod. An air supply pipe is provided on the right side of the second outer cover and below the first extension rod. A connecting groove is provided on the inner side wall of the second outer cover. A baffle plate is installed inside the connecting groove via a rotating shaft. A scraping roller is rotatably installed at the center of the inner part of the second outer cover. The top of the scraping roller is fixedly connected to the second toothed disc on the right side. A receiving groove is provided on the vertical side wall of the scraping roller.
[0012] In one embodiment, the extrusion assembly includes a first outer cover, a second extension rod is mounted on the right side of the lower horizontal section of the support frame, the first outer cover is mounted on the left end of the second extension rod, a cylindrical roller is rotatably mounted inside the first outer cover, and the top of the cylindrical roller is fixedly connected to the second toothed disc on the right side.
[0013] In one embodiment, the external cleaning component includes a limiting block. A groove is formed on the front surface of the bottom frame, and the limiting block is slidably installed inside the groove. The rear of the limiting block is connected to the closing plate. An outer limiting sleeve is rotatably installed on the front right side of the limiting block. An inner limiting plate is reciprocally installed on the right side of the outer limiting sleeve along its length.

[0015] In one embodiment, the adjusting assembly includes a second spring frame, a fixing groove is provided below the left vertical section of the sealing plate, a backstop rod is slidably installed inside the fixing groove, a second spring frame is installed between the horizontal section of the backstop rod and the bottom of the fixing groove, and the sealing plate and the backstop rod are both provided with elongated holes, and a plug rod is detachably installed inside the elongated holes.
[0016] In summary, the present invention has at least one of the following beneficial technical effects:
[0017] 1. In this invention, the bottom frame rotates around the manhole cover's axis. Under the action of the first spring frame, the anti-reverse rod and the sealing plate repeatedly move towards and away from the manhole cover. The anti-reverse rod, under the action of the first spring frame, remains in contact with the edge wall of the square groove, and one side of the sealing plate always corresponds to the edge of the square groove, thus ensuring that all the asphalt within the bottom frame remains within the square groove. During the rotation of the bottom frame, the spreading plate at the bottom of the bottom frame spreads the spilled asphalt, keeping it flat and thus fully spreading it around the edge of the manhole cover. Simultaneously, the movement of the sealing plate drives the outer cleaning component to clean the existing road surface outside the square groove, and the inner cleaning mechanism can clean up any spilled asphalt at the manhole cover.
[0018] 2. The present invention, through the arrangement of the first and second toothed discs, enables the cylindrical roller and the scraping roller to rotate simultaneously. The rotation of the cylindrical roller squeezes the asphalt within the manhole cover area to the outside of the manhole cover. The scraping roller is located on one side of the bottom frame. This allows the scraping roller to both prevent some asphalt from falling onto the manhole cover and scrape the remaining asphalt into the collection trough through its own rotation. When the collection trough rotates to the conveying port of the second outer cover, the suction of the external negative pressure device can transport the asphalt in the collection trough to the outside through the air pipe. This ensures the cleanliness of the manhole cover area.
[0019] 3. In this invention, while the bottom frame rotates, the anti-blocking frame drives the crossbar to rotate synchronously via an electrically controlled telescopic rod. At the same time, the crossbar connected to the anti-blocking frame rotates along the spiral groove on the outer wall of the upright. During this process, the crossbar causes the anti-blocking rod to drive the vibrator to move downward. When the bottom frame rotates in the opposite direction, the anti-blocking rod will drive the vibrator to move upward. The up-and-down moving vibrator agitates the asphalt inside the top frame, preventing the asphalt inside the top frame from becoming blocked. Attached Figure Description

[0041] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0042] like Figure 1 , Figure 10-14As shown, a hot-mix asphalt paving equipment includes a base plate 1, a support frame 2, uprights 3, an anti-blocking mechanism 4, a paving mechanism 5, and an internal cleaning mechanism 6. The uprights 3 are installed at the top axial position of the base plate 1. A U-shaped support frame 2 is set on the outer wall of the uprights 3 and above the base plate 1. The uprights 3 and the support frame 2 can slide up and down relative to each other and rotate relative to each other. The internal cleaning mechanism 6 is set along the annular surface of the base plate 1. The paving mechanism 5 is set on the right side of the base plate 1. The anti-blocking mechanism 4 is set between the paving mechanism 5 and the uprights 3. A hydraulic rod is installed on the top of the uprights 3, and one end of the top of the hydraulic rod is connected to a transport vehicle.
[0043] like Figure 1-3 , Figure 5 and Figure 6 As shown, the paving mechanism 5 includes a top frame 53. An electrically controlled telescopic rod 21 is installed on the right side of the horizontal section of the support frame 2. The top frame 53 is installed at the right end of the electrically controlled telescopic rod 21. An inverted U-shaped bottom frame 51 is installed at the bottom of the top frame 53. A discharge port is opened at the top of the bottom frame 51. A spreader 55 is installed below the front surface of the bottom frame 51. An external cleaning component 52 is provided on the right side of the front surface of the bottom frame 51. A positioning frame is installed on the right side of the rear surface of the bottom frame 51. A U-shaped closing plate 54 is slidably installed on the right end of the bottom frame 51. The left end of the closing plate 54 is located directly below the discharge port and its width is greater than the width of the discharge port. A caster wheel 542 is installed below the right vertical section of the closing plate 54. A first spring frame 56 is installed between the right vertical section of the closing plate 54 and the right end of the bottom frame 51. A T-shaped anti-reverse rod 57 is slidably installed below the left vertical section of the closing plate 54. An adjustment component 58 is installed between the anti-reverse rod 57 and the closing plate 54.
[0044] In practice, the paving equipment is moved to the manhole cover by a transport vehicle. The casters 542 move synchronously along the ground, positioning the base plate 1 directly above the manhole cover. Then, the external hydraulic rods on the transport vehicle move the uprights 3 and the base plate 1 downwards until the base plate 1 is pressed firmly against the manhole cover. The hydraulic rods prevent the base plate 1 from detaching from the center of the manhole cover. Next, the length of the electrically controlled telescopic rod 21 is adjusted so that the base frame 51 aligns with the edge of the manhole cover. The anti-reverse rod 57 is moved and placed in the cut square groove. During this process, the anti-reverse rod 57 moves the sealing plate 54 synchronously, compressing the first spring frame 56. The compressed first spring frame 56 provides a reverse pulling force to the sealing plate 54. Under this reverse pulling force, the anti-reverse rod 57 is pressed tightly against the wall of the square groove, and the left end of the sealing plate 54 is positioned above the wall of the square groove. The asphalt mixture is then poured into the top frame 53. The asphalt in the top frame 53 flows out from the outlet of the bottom frame 51. The sealing plate 54 always blocks the corresponding part on the right end of the outlet. The blocking effect of the sealing plate 54 prevents it from flowing into areas outside the square groove. Next, the bottom frame 51 is pushed to rotate around the manhole cover axis. Under the action of the first spring frame 56, the anti-reverse rod 57 and the sealing plate 54 repeatedly move towards and away from the manhole cover. The pull of the first spring frame 56 ensures that the anti-reverse rod 57 always keeps in contact with the edge wall of the square groove, and thus one side of the sealing plate 54 always corresponds to the edge of the square groove. This allows all the asphalt in the base frame 51 to remain in the square groove. During the rotation of the base frame 51, the paving plate 55 at the bottom of the base frame 51 will spread the flowing asphalt, keeping the asphalt flat. This allows for full spreading at the edge of the manhole cover. At the same time, the movement of the sealing plate 54 can drive the outer cleaning component 52 to clean the original road surface outside the square groove. The inner cleaning mechanism 6 can clean up the asphalt spilled at the manhole cover. After cleaning is completed, the hydraulic rod can drive the main rod 3 and the base plate 1 to move up and reset, and the transport vehicle can tow the paving equipment to the next working point.
[0045] like Figure 1As shown, the anti-blocking mechanism 4 includes an anti-blocking frame 43. The anti-blocking frame 43 is installed on the top of the electrically controlled telescopic rod 21. A horizontal rod 44 is slidably installed inside the anti-blocking frame 43. The upright rod 3 consists of a sleeve with a spiral groove 31 on its outer wall and an inner rod slidably installed inside the sleeve. The base plate 1 is installed at the lower end of the inner rod. An external hydraulic rod is connected to the upper end of the inner rod. The support frame 2 is rotatably connected to the sleeve. The left end of the horizontal rod 44 is slidably connected to the spiral groove 31. A U-shaped anti-blocking rod 42 is installed at the right end of the horizontal rod 44. A vibrating rod 41 is installed on the right side of the anti-blocking rod 42. The vibrating rod 41 is located at... Inside the top frame 53, during operation, while the bottom frame 51 rotates, the anti-blocking frame 43 drives the crossbar 44 to rotate synchronously via the electrically controlled telescopic rod 21. At the same time, the crossbar 44 connected to the anti-blocking frame 43 rotates along the spiral groove 31 on the outer side wall of the upright 3. During this process, the crossbar 44 causes the anti-blocking rod 42 to drive the vibrator 41 to move downward. When the bottom frame 51 rotates in the opposite direction, the anti-blocking rod 42 drives the vibrator 41 to move upward. The up-and-down moving vibrator 41 agitates the asphalt inside the top frame 53, preventing the asphalt inside the top frame 53 from becoming blocked.
[0046] like Figure 4 As shown, the adjusting component 58 includes a second spring frame 582. A fixing groove 541 is provided below the vertical section on the left side of the sealing plate 54. A backstop rod 57 is slidably installed inside the fixing groove 541. A second spring frame 582 is installed between the horizontal section of the backstop rod 57 and the bottom of the fixing groove 541 and sleeved on the outer wall of the backstop rod 57. Both the sealing plate 54 and the backstop rod 57 have elongated holes inside. An insert rod 581 is detachably installed inside the elongated holes. In specific operation, after the asphalt paving is completed, the insert rod 581 is pulled outward. Then, the compressed second spring frame 582 will push the backstop rod 57 to slide upward and place the backstop rod 57 on the road surface outside the square groove. Then, the bottom frame 51 can be rotated to further smooth the poured asphalt road surface with the paving plate 55 at the bottom of the bottom frame 51.
[0047] like Figure 1 , Figure 2 and Figure 12As shown, the external cleaning component 52 includes a limiting block 521. A groove is provided on the front surface of the bottom frame 51. The limiting block 521 is slidably installed inside the groove. The rear of the limiting block 521 is connected to the closing plate 54. An outer limiting sleeve 522 is rotatably installed on the front right side of the limiting block 521. An inner limiting plate 523 is slidably installed on the right side of the outer limiting sleeve 522 along its length. A storage box 524 is installed on the front right side of the bottom frame 51. The storage box 524 and the inner limiting plate 523 are rotatably connected. Next, during actual operation, as the sealing plate 54 moves continuously, it will drive the limiting block 521 to move synchronously, ensuring that the limiting block 521 is always at the edge position outside the square groove. The spilled asphalt can be collected through the outer limiting sleeve 522 and the inner limiting plate 523. When the sealing plate 54 drives the limiting block 521 to move to the right, the asphalt collected by the outer limiting sleeve 522 and the inner limiting plate 523 can be moved into the collection box 524, thereby ensuring the cleanliness of the road surface.
[0048] like Figure 7-8 As shown, the internal cleaning mechanism 6 includes a first toothed disc 62. The first toothed disc 62 is installed on the outer wall of the upright 3 and in the inner groove of the support frame 2. The two sides of the first toothed disc 62 are meshed with second toothed discs 64. A scraping component 63 is installed below the left second toothed disc 64, and a squeezing component 61 is installed below the right second toothed disc 64.
[0049] like Figure 8-9 As shown, the scraping assembly 63 includes a second outer cover 632. A first extension rod is installed on the left side of the lower horizontal section of the support frame 2. The second outer cover 632 is installed on the left end of the first extension rod. An air supply pipe 633 is provided on the right side of the second outer cover 632 and below the first extension rod. A connecting groove is provided on the inner side wall of the second outer cover 632. A baffle plate 634 is installed inside the connecting groove via a rotating shaft. A scraping roller 631 is rotatably installed at the center of the inside of the second outer cover 632. The top of the scraping roller 631 is fixedly connected to the second toothed disc 64 on the left side. A storage groove is provided on the vertical side wall of the scraping roller 631. Figure 9 As shown.
[0050] like Figure 8As shown, the extrusion assembly 61 includes a first outer cover 611. A second extension rod is installed on the right side of the lower horizontal section of the support frame 2. The first outer cover 611 is installed at the right end of the second extension rod. A cylindrical roller 612 is rotatably installed inside the first outer cover 611. The top of the cylindrical roller 612 is fixedly connected to the second toothed disc 64 on the right side. In actual operation, during the rotation of the bottom frame 51, the support frame 2 will simultaneously drive the first outer cover 611 and the second outer cover 632 to rotate around the upright 3 as the axis. Since both second toothed discs 64 are engaged with the first toothed disc 62, this allows the extrusion assembly to rotate smoothly during the rotation process. The cylindrical roller 612 and the scraping roller 631 rotate on their own, and the scraping roller 631 is located on the side close to the bottom frame 51. This allows the scraping roller 631 to prevent some asphalt from falling onto the manhole cover, and the rotation of the cylindrical roller 612 to squeeze the asphalt within the manhole cover area to the outside of the manhole cover. The rotation of the scraping roller 631 can also scrape off the residual asphalt, allowing the asphalt to move into the collection groove opened by the scraping roller 631. When the collection groove rotates to the conveying port of the second outer cover 632, the suction of the external negative pressure device can transport the asphalt in the collection groove to the outside through the air pipe 633.
[0051] The working principle of this invention is as follows: First, the paving equipment is pulled above the manhole cover by a transport vehicle, so that the base plate 1 is directly above the center of the manhole cover. Then, the base plate 1 below the upright 3 is moved downward by the external hydraulic rod. When the base plate 1 contacts the manhole cover, the pressure of the hydraulic rod can prevent the base plate 1 from leaving the center of the manhole cover. The length of the electrically controlled telescopic rod 21 is adjusted so that the bottom frame 51 corresponds to the edge of the manhole cover. After the anti-reverse rod 57 is placed in the cut square groove, the asphalt mixture is poured into the top frame 53. The asphalt in the top frame 53 will flow out from the bottom of the bottom frame 51.
[0052] Step 2: Push the bottom frame 51 to rotate around the axis of the manhole cover. During this process, all the asphalt in the bottom frame 51 is left in the square groove. The asphalt that flows out can be spread by the paving plate 55 at the bottom of the bottom frame 51 to keep the asphalt flat.
[0053] Step 3: While paving, the movement of the sealing plate 54 can drive the outer cleaning component 52 to clean the original road surface outside the square groove, and the inner cleaning mechanism 6 can clean up the asphalt spilled at the manhole cover.
