Description

Technical Field

[0001] This invention relates to the field of road construction technology, and in particular to a crack sealing device for road construction. Background Technology

[0002] With rapid economic development and continuous social progress, more and more wide roads are being built. However, as the service life of the roads increases and more and more vehicles travel on them, cracks are easily generated. In order to facilitate the repair of cracks on the roads, road crack sealing devices have emerged. Due to their ease of use and ability to repair cracks, they are favored by construction workers.

[0003] Existing crack sealing devices typically involve workers aligning a crack sealing gun on a mobile platform with the cracks in the ground, and then controlling a material pump to seal the cracks. However, when the cracks are curved, the crack sealing gun needs to be moved. Since the crack sealing gun is fixed on the mobile platform, workers need to push the platform back and forth to align the crack sealing gun with the crack. This method increases the labor intensity of workers and reduces the efficiency of crack sealing. Summary of the Invention

[0022] One end of each of the drum tubes is fixedly connected to an air-blowing plate via a metal telescopic tube.

[0023] In some embodiments, the mobile platform is further provided with a pushing component and a storage tank.

[0024] In some embodiments, the bottom of the mobile platform is equipped with casters.

[0025] Compared with the prior art, the present invention has at least the following beneficial effects:

[0026] 1. By incorporating a regional adjustment component, when filling cracks in the ground, the filling pipe, fixed to a sliding plate, grouts the cracks. When the crack is curved, adjusting cylinder number one causes semicircular block number three to move along a linear guide rail, adjusting the filling pipe left and right. Alternatively, adjusting cylinder number two causes semicircular block number four to move along the linear guide rail via the sliding plate, adjusting the filling pipe forward and backward. Simultaneously adjusting cylinders one and two allows the filling pipe on the sliding plate to be adjusted at a 45-degree angle. This regional adjustment component allows the filling pipe to be moved and adjusted within a small area when filling curved cracks, eliminating the need for manual adjustment of the moving platform, reducing labor intensity, and improving the filling efficiency of the device.

[0027] Second, by setting up a material pushing component, when filling cracks, the drive motor can be started. The drive motor drives the active gear on the main shaft on both sides to rotate, which in turn drives the screw on the driven gear to rotate. During the rotation of the screw, the push rod on the screw tube moves forward, allowing the material pushing plate to push the excess filling material squeezed out of the filling tube into the crack. This makes full use of the filling material and saves resources. At the same time, during the movement of the push rod, it can slide within the limit track through the limit slider. The limit slider pulls the limit frame on the telescopic rod to limit the push rod, making its use more stable.

[0028] Third, by setting up an air-blowing component, before filling the crack, the air blower can be started to blow air into the hollow connecting plate through the air-blowing pipe. Then, the arc-shaped air-blowing plates on each branch pipe of the hollow connecting plate will treat the debris inside the crack, preventing the filling material from not adhering to the crack when filling it. At the same time, the direction of air blowing can be adjusted by the metal telescopic pipe. Attached Figure Description

A sliding guide rail 511 is fixedly connected to the lower part of the vertical rod of the bracket 509. A linear guide rail 512 is vertically connected to the linear guide rail 511, and the linear guide rail 512 can slide back and forth along the sliding guide rail 511 (the extension direction of the sliding guide rail 511 is the movement direction of the moving platform 1). A second semi-circular groove is opened on the linear guide rail 512, and a third semi-circular block 516 is located inside the second semi-circular groove.

[0048] During use, before filling the cracks, the blower 701 can be started to blow air into the hollow connecting plate 704 through the blower pipe 702. Then, the arc-shaped blower plates 707 on each of the branch blower pipes 705 on the hollow connecting plate 704 are used to remove debris inside the crack, preventing the filling material from not adhering to the crack during filling. The direction of the air blowing can be adjusted through the metal telescopic pipe 706. Then, the cracks on the ground are filled through the filling pipe 521 on the sliding plate 517. When the crack is curved, the first adjusting cylinder 505 can be adjusted. The extension and retraction of the first adjusting cylinder 505 causes the third semi-circular block 516 to drive the linear guide rail. 512 moves on the sliding guide rail 511 to adjust the crack filling tube 521 left and right. Alternatively, adjusting the second adjusting cylinder 506 can drive the fourth semicircular block 518, which in turn drives the slide plate 517 to move on the linear guide rail 512 to adjust the crack filling tube 521 back and forth. Simultaneously adjusting the first adjusting cylinder 505 and the second adjusting cylinder 506 can make the crack filling tube 521 on the slide plate 517 tilted at 45 degrees. Through the area adjustment component 5, when filling curved cracks, the crack filling tube 521 can be moved and adjusted in a small area, eliminating the need for workers to adjust the moving platform 1, reducing the labor intensity of workers, and improving the crack filling efficiency of the crack filling device. While filling the crack, the drive motor 614 can be started. The drive motor 614 drives the drive gear 612 on the main rotating shaft 611 on both sides to rotate, which in turn drives the screw 601 on the driven gear 609 to rotate. During the rotation of the screw 601, the push rod 604 on the screw tube 602 moves forward, which pushes the excess filling material squeezed out by the filling tube 521 into the crack by the push plate 607. This makes full use of the filling material and saves resources. At the same time, during the movement, the push rod 604 can slide in the limiting track 608 through the limiting slider 615. The limiting slider 615 pulls the limiting frame 617 on the telescopic rod 616 to limit the push rod 604, making its use more stable.
