Bituminous pavement damage repairing and filling device

Abstract

The invention discloses an asphalt pavement damage repairing and filling device, and relates to the technical field of repairing and filling devices. The whole chassis is of a rectangular structure, two wheels are coaxially installed on the front side position of the bottom of the chassis, a universal wheel is locked and fixed to the middle position of the rear side of the bottom of the chassis, and two L-shaped push rods are welded to the rear side position of the top end of the chassis in a left-right symmetrical vertical supporting mode; a horizontal supporting ring is welded to the top end of the front half portion of the base plate in a supporting mode, a star-shaped support is welded to the interior of the horizontal supporting ring, an annular fireproof cover is welded to the outer circle of the circumference of the base plate, and a repairing liquid box is welded to the top end of the annular fireproof cover in a supporting mode. When the butt joint slides up and down to be in butt joint with and separated from the butt joint disc during disassembly and replacement of the gas tank, the limiting swing rod can be driven to swing, retract and expand in a linkage meshing mode, and the problems that when the gas tank is disassembled and replaced, a swing switch and the limiting swing rod need to be manually operated additionally, and use is troublesome, inconvenient and strenuous are solved.

Description

technical field [0001] The invention relates to the technical field of pavement repairing devices, in particular to an asphalt pavement damage repairing and filling device. Background technique [0002] Asphalt pavement has the advantages of firmness, wear resistance and long service life, but due to long-term overload operation and natural factors, it is likely to be damaged before the maintenance period. This requires timely repairs to the road surface. Most of the existing pavement repairs are to pave one deck of asphalt or cement on the damaged pavement, which requires an asphalt pavement damage repair filling device. [0003] Most of the limit barrier components for heating gas tanks on existing road surface repair devices have certain design defects, and most of their driving structures cannot be combined with the driving mechanism of the gas tank gas connection parts, resulting in the need for additional manual switches when disassembling and replacing gas tanks The...
