Description

Technical Field

[0001] This utility model relates to the field of engineering machinery, and in particular to a road pothole rapid repair paver. Background Technology

[0002] When traffic accidents cause localized road damage, underground pipeline bursts, or improper construction leads to road collapses, requiring immediate repairs to eliminate safety hazards, traditional manual repairs or small-scale mechanical operations involve multiple steps and can take hours or even days, making it difficult to meet the needs for rapid traffic restoration.

[0003] Existing technologies, such as the utility model with publication number CN221895487U, relate to the field of traffic engineering technology and propose a road paver. The paver includes a base plate, a material box fixedly connected to the center of the inner wall of the base plate, an inlet at the center of the top of the material box, an outlet at the center of the bottom of the material box, an adjusting groove at the bottom of the inner wall of the material box located on the right side of the outlet, and two opposing sliding grooves at the bottom of the inner wall of the material box located on the front and rear sides of the center of the outlet, respectively. A fixed platform is fixedly connected to the bottom of the adjusting groove. In this utility model, the coordination of the material box, outlet, adjusting groove, fixed platform, motor, gears, rack and pinion, adjusting plate, and sliding grooves achieves the adjustment of the material flow rate. The appropriate flow rate can be adjusted according to actual paving needs and the needs of the workers, thereby avoiding material waste to a certain extent and further improving the flexibility of the device.

[0004] The inventors discovered in their daily work that existing equipment has a problem: due to the limited scraper area, it requires repeated piling and compacting of materials to repair road surfaces with different degrees of damage, which reduces construction efficiency and prevents rapid repair, thus hindering the quick restoration of normal traffic flow.

A connecting block is fixedly connected to the surface of the connecting block. A positive and negative threaded rod is threadedly connected to the surface of the connecting block. A limit block is fixedly connected to one side of the positive and negative threaded rod. A slot is formed on the surface of the scraper and a slot is formed on the surface of the scraper.

[0007] Furthermore, a hanging rod is fixedly connected to the lower surface of the mounting base, a stepper motor is provided below the mounting base, the surface of the stepper motor is fixedly connected to the hanging rod, a sub-plate is provided below the mounting base, the surface of the sub-plate is tightly fitted with the inner surfaces of scraper one and scraper two, a base is fixedly connected to the inner surface of the sub-plate, a slot is opened on the surface of the base, and a groove is opened on the inner wall of the slot.

[0008] Furthermore, the drive end of the stepper motor is connected to a telescopic rod, a support plate is fixedly connected to the surface of the telescopic rod, a protrusion is fixedly connected to the surface of the support plate, the protrusion is slidably connected to the inner wall of the groove, and a card seat is fixedly connected to the surface of the sub-plate, with an insertion hole on the surface of the card seat.

[0009] Furthermore, the surface of the mounting base is provided with a sliding groove, the inner wall of the sliding groove is slidably connected with a pressure plate, the lower surface of the pressure plate is fixedly connected with a first limiting post, the lower surface of the pressure plate is fixedly connected with a second limiting post, and the lower surface of the pressure plate is fixedly connected with an insertion rod.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting an adjustment component, during use, rotating the turntable causes the positive and negative threaded rods to rotate. Utilizing the positive and negative threads on the surface of the threaded rods, connecting blocks one and two, which are threaded together on the surface of the threaded rods, move towards each other during rotation, thereby achieving the effect of separating scraper one and scraper two to both sides. After separation, the stepper motor is turned on, pushing the auxiliary plate forward until it stops at the same plane as scraper one and scraper two. With the special structural design of its rear base, the auxiliary plate can move downwards and diagonally to a position level with the bottom surface of the scraper while moving forward, thereby achieving the effect of lengthening the scraper. After the extension is completed, the pressure plate is used to finally fix scraper one, scraper two, and the auxiliary plate. By setting an adjustment component, the scraper width can be quickly changed, reducing the number of back-and-forth operations. This significantly improves efficiency, especially in the repair of large-area road potholes, and increases the overall work efficiency. Moreover, the wider scraper can cover a larger area at once, reducing seams and unevenness. Attached Figure Description

[0015] Please see Figure 1-8 This utility model provides a technical solution: a road pothole rapid repair paver, including a vehicle body 1, a handrail 2, a mounting base 3 and an adjustment component 4. The handrail 2 is fixedly connected to the upper surface of the vehicle body 1, and the mounting base 3 is fixedly connected to the surface of the vehicle body 1. The adjustment component 4 includes a scraper 41 and a positive and negative threaded rod 43.

[0016] The specific settings and functions of adjustment component 4 will be explained below.

[0017] In this embodiment: scraper 41 is slidably connected to the surface of mounting base 3, connecting block 42 is fixedly connected to the surface of scraper 41, a threaded rod 43 is provided below mounting base 3, the threaded rod 43 is threadedly connected to the surface of connecting block 42, a turntable 44 is rotatably connected to one side of the threaded rod 43, scraper 48 is slidably connected to the surface of mounting base 3, scraper 48 and scraper 41 are symmetrically arranged, connecting block 49 is fixedly connected to the surface of scraper 48, connecting block 49 is fixedly connected to the surface of connecting block 49, threaded rod 43 is threadedly connected to the surface of connecting block 49, a limit block 410 is fixedly connected to one side of the threaded rod 43, a slot 429 is opened on the surface of scraper 41, and a slot 430 is opened on the surface of scraper 48.

[0018] In this embodiment: scraper 1 41 and scraper 2 48 are symmetrically arranged. Using the positive and negative threads of the positive and negative threaded rod 43, the turntable 44 rotates and the positive and negative threaded rod 43 rotates. Connecting block 1 42 and connecting block 2 49 move towards each other, thereby achieving the effect of separating scraper 1 41 and scraper 2 48 to both sides. The limiting block 410 ensures that connecting block 2 49 is disengaged from the mounting base 3.

[0019] Specifically, a hanger 45 is fixedly connected to the lower surface of the mounting base 3, a stepper motor 46 is provided below the mounting base 3, the surface of the stepper motor 46 is fixedly connected to the hanger 45, a sub-plate 411 is provided below the mounting base 3, the surface of the sub-plate 411 is tightly fitted with the inner surfaces of scraper 1 41 and scraper 2 48, a base 412 is fixedly connected to the inner surface of the sub-plate 411, a slot 413 is provided on the surface of the base 412, and a groove 414 is provided on the inner wall of the slot 413.

[0020] Specifically, the drive end of the stepper motor 46 is connected to a telescopic rod 47, the surface of the telescopic rod 47 is fixedly connected to a support plate 415, the surface of the support plate 415 is fixedly connected to a protrusion 416, the protrusion 416 is slidably connected to the inner wall of the groove 414, the surface of the sub-plate 411 is fixedly connected to a card holder 417, and the surface of the card holder 417 is provided with an insertion hole 428.

[0021] In this embodiment: the stepper motor 46 operates the telescopic rod 47 to push the sub-plate 411 forward, so that the sub-plate 411 is pushed to the same plane as scraper 1 41 and scraper 2 48.

[0022] In this embodiment: due to the separation of scraper 1 41 and scraper 2 48, the bottom of the sub-plate 411 is unsupported and descends under the influence of gravity. To ensure that its bottom surface is level with the bottom of scraper 1 41 and scraper 2 48, the base 412 provided thereafter has a slot 413. The slot 413 is used to fix the sub-plate 411 and the support plate 415. The groove 414 inside the slot 413 is used to lock the protrusion 416 and connect the support plate 415 and the sub-plate 411. The length of the groove 414 is such that when the sub-plate 411 is supported, the protrusion 416 is located in the lower part of the groove 414. When unfolded, the sub-plate 411 moves downward under its own weight, and the protrusion 416 is stuck in the upper part of the groove 414, so that the sub-plate 411 is level with the bottom of scraper 1 41 and scraper 2 48.

[0023] Specifically, the surface of the mounting base 3 is provided with a sliding groove 431, and a pressure plate 418 is slidably connected to the inner wall of the sliding groove 431. A limit post 419 is fixedly connected to the lower surface of the pressure plate 418, a second limit post 421 is fixedly connected to the lower surface of the pressure plate 418, and an insertion rod 420 is fixedly connected to the lower surface of the pressure plate 418. In this embodiment: when the pressure plate 418 is not fixed, it will slide down the slide groove 431 at a constant speed until it reaches the bottom of the slide groove 431. The first limiting post 419 fixes the scraper 41 through the slot 429 opened on the surface of the scraper 41. The second limiting post 421 fixes the scraper 48 through the slot 430 opened on the surface of the scraper 48. The insertion rod 420 fixes the sub-plate 411 by inserting into the insertion hole 428 of the card seat 417 on the surface of the sub-plate 411.

[0024] Specifically, a second fixing seat 427 is fixedly connected to the surface of the mounting base 3, a first fixing seat 422 is fixedly provided on the upper surface of the pressure plate 418, a pin 423 is connected to the surface of the first fixing seat 422, a locking block 424 is fixedly connected to the surface of the pin 423, and a square groove 425 is provided on the surface of the first fixing seat 422.

[0025] Specifically, a limiting ring 426 is fixedly connected to the surface of the pin 423. The side of the limiting ring 426 away from the fixing seat 422 is fixedly connected to the surface of the pin 423. A limiting ring 432 is fixedly connected to the surface of the pin 423. The side of the limiting ring 432 away from the fixing seat 427 is fixedly connected to the surface of the pin 423.

[0026] In this embodiment: the first limiting ring 426 is to ensure that the pin 423 does not slide out of the second fixing seat 427 when the pin 423 fixes the first fixing seat 422; the second limiting ring 432 is to ensure that the pin 423 does not slide out from the other side of the second fixing seat 427 when the pin 423 is pulled out of the first fixing seat 422; the locking block 424 is set to lock the translation of the first fixing seat 422 to ensure stability during locking.

[0027] Working principle: When encountering large areas of road potholes, the rotating turntable 44 drives the positive and negative threaded rods 43 to rotate. Utilizing the positive and negative thread characteristics on their surfaces, the connecting blocks 42 and 49, which are respectively threaded to the positive and negative threaded rods 43, move in opposite directions. This, in turn, causes scraper 41 and scraper 48 to separate to both sides. Once the scrapers are separated, the stepper motor 46 is started, driving the secondary plate 411 forward. During the forward movement of the secondary plate 411, due to the separation of scraper 41 and scraper 48, the bottom of the secondary plate 411 is unsupported and is affected by gravity. As the sub-plate 411 descends, to ensure its bottom surface is flush with the bottoms of scraper 1 41 and scraper 2 48, a slot 413 is provided on the subsequent base 412. The slot 413 is used to fix the sub-plate 411 and the support plate 415. The groove 414 inside the slot 413 is used to lock the protrusion 416 and connect the support plate 415 and the sub-plate 411. The length of the groove 414 ensures that when the sub-plate 411 is supported, the protrusion 416 is located in the lower part of the groove 414. When unfolded, the sub-plate 411 moves downward under its own weight, while the protrusion 416 is locked in the upper part of the groove 414. The process involves aligning the sub-plate 411 with the bottom of scraper 1 41 and scraper 2 48, then rotating the turntable 44 to return scraper 1 41 and scraper 2 48 to the center, thus tightening the sub-plate 411 and completing the initial fixation. This increases the effective length of the scraper. After the scraper is lengthened, the pin 423 is rotated to align the locking block 424 on the surface of the pin 423 with the square groove 425 of the fixing seat 1 422. The pin 423, used for limiting, is then pulled out along the square groove 425, releasing the pressure plate 418 from its fixation. The pressure plate 418 slides down along the sliding groove 431 on its back, and the insertion rod 42 on its lower surface... The 0 is inserted into the insertion hole 428 of the card holder 417 on the surface of the sub-plate 411. The limiting post 419 and the limiting post on its surface are respectively inserted into the slot hole 429 and the slot hole 430 opened on the surface of scraper 41 and scraper 48, so as to finally fix scraper 41, scraper 48 and sub-plate 411. By setting the adjustment component 4, the scraper width can be quickly changed, reducing the number of back-and-forth operations. Especially in the repair of large-area road potholes, efficiency is significantly improved, the overall operation efficiency is improved, and the wide scraper can cover a larger area at one time, reducing joints and unevenness.
