Multifunctional asphalt crack sealing machine

Abstract

The utility model relates to a multifunctional asphalt joint filling machine, which belongs to road construction facilities. Including the frame; the asphalt melting box is set at one end of the frame, the upper part is equipped with a box cover, the outer wall and the bottom wall form an oil heating jacket, and the lower part forms a liquefied gas combustion mechanism chamber; the liquefied gas tank carrying box is set at the end of the frame The other end: the liquefied gas combustion mechanism is located in the cavity of the liquefied gas combustion mechanism; the molten asphalt lead-out box is set at the lower part of the asphalt melting box; the joint filling mechanism is set on the molten asphalt lead-out box; the operating mechanism is mounted on the asphalt melting box and one side of the liquefied gas tank carrying box, it also includes a frame travel guide mechanism, which includes a guide wheel guide, a guide wheel guide fixing seat, a guide wheel and a spring, the guide wheel guide fixing seat is fixed on the frame, and the guide wheel guide is fixed On the guide wheel catheter fixing seat, the guide wheel is set on the guide wheel seat, and the spring is sleeved on the lifting shaft of the guide wheel seat. The upper end of the spring is supported on the top wall of the guide wheel catheter cavity, and the lower end is supported on the dial pin. . It can reflect the flexibility requirements of joint filling operations.

Description

technical field [0001] The invention belongs to the technical field of road construction facilities, and in particular relates to a multifunctional asphalt joint filling machine. Background technique [0002] Previously, the road construction and municipal facility maintenance departments usually filled the cracks on the asphalt pavement and the expansion joints reserved on the cement pavement by hand pouring. Undoubtedly, this operation method has low work efficiency and labor-intensive labor. The strength and the quality of joint filling vary with the experience and sense of responsibility of the constructors and waste materials, and the mechanical asphalt joint filling machine can basically make up for these deficiencies. [0003] In the published Chinese patent documents, various technical information about asphalt joint filling machines can be seen, such as the "friction type asphalt pavement joint filling machine" recommended by document A), the authorized announcement...

AI Technical Summary

Problems solved by technology

But there are also opposite situations. For example, when it is necessary to fill the expansion joints reserved on the cement pavement, the asphalt joint filling machine should meet the requirements of forward travel. Only in this way can the joints be filled quickly, otherwise the asphalt will overflow the expansion joints and spread To the road surface on both sides of the expansion joint, it not only causes waste of raw materials (asphalt), but also affects the appearance of the road surface

However, it must be ensured that the joint filling nozzle (also known as the asphalt discharge nozzle) of the joint filling pipe of the joint filling mechanism is always aligned with the expansion joint during the fast forward walking process, and is not limited to the above patent disclosures. The seam filling mechanism cannot meet this requirement
