Multifunctional asphalt crack sealing machine

Abstract

The invention provides a multifunctional asphalt crack sealing machine belonging to road construction facilities. The machine comprises a rack, an asphalt melting box, a liquid gas storage tank carrying box, a liquid gas combustion mechanism, a molten asphalt outlet box, a crack sealing mechanism, a control mechanism and a rack travelling guide mechanism, wherein the asphalt melting box is arranged at one end of the rack; an box cover is arranged on the upper part of the asphalt melting box; an oil heating jacket is formed on the outer wall and bottom wall of the asphalt melting box; a liquid gas combustion mechanism cavity is formed below the asphalt melting box; the liquid gas storage tank carrying box is arranged at the other end of the rack; the liquid gas combustion mechanism is arranged in the liquid gas combustion mechanism cavity; the molten asphalt outlet box is arranged on the lower part of the asphalt melting box; the crack sealing mechanism is arranged on the molten asphalt outlet box; the control mechanism is carried on one side of the asphalt melting box and the liquid gas storage tank carrying box; the rack travelling guide mechanism comprises a guide wheel conduit, a guide wheel conduit fixing seat, a guide wheel and a spring; the guide wheel conduit fixing seat is fixed on the rack; the guide wheel conduit is fixed on the guide wheel conduit fixing seat; the guide wheel is arranged on a guide wheel seat; the spring is sleeved on a guide wheel seat lifting shaft; and the upper end of the spring is supported on the top wall of a guide wheel conduit cavity, and the lower end thereof is supported on a poking pin. The machine can meet the requirement of crack sealing operation for flexibility.

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
