Two-crawler material paving machine

Abstract

The invention relates to a two-crawler material paving machine capable of realizing self-site transfer, which comprises a main frame, wherein two walking crawlers are respectively arranged on two sides of the main frame, and a material distributing device and a paving device are arranged below the main frame; the walking crawlers are mounted below a side beam of the main frame through one or two mounting seats which can rotate in the horizontal plane, the walking crawlers can rotate around the mounting seats which are used as fixed shafts, and the mounting seats are connected with mounting parts of the walking crawlers through connecting parts; and at least one walking crawler is mounted below the side beam of the main frame through the two mounting seats, at least one walking crawler can rotate around one of the mounting seat which is used as the fixed shaft, when the walking crawlers rotate around the fixed shafts, an independent walking device is detachably mounted on the other mounting seat, and the independent walking device is connected with the other mounting seat through the connecting part; and steering mechanisms are arranged between the walking crawlers and the main frame. The two-crawler material paving machine can solve the problems that the existing large two-crawler material paving machine only adopts a large transport vehicle for transmission and can not carry out the site transfer conveniently.

Description

technical field [0001] The invention relates to a material paver, in particular to a two-crawler type material paver which can be easily transferred. Background technique [0002] In recent years, China's road construction projects are increasing, mainly in the construction of grade roads, such as first-class roads, expressways, etc. These roads are wide, and the construction units have high quality requirements, and the paving of the stable layer requires full-width or half-width paving at one time Forming, in order to meet the paving needs of wide pavement, wide pavers have also begun to appear on the market. For example, the Chinese utility model patent No. 00260856.1 discloses a base stabilized soil paver, which consists of a receiving vehicle, a cloth plow, a primary paving module, a secondary paving module, a frame, a lifting column, an operating table, and a sensor. It is composed of bracket, power assembly, crawler frame, support wheel, walking track and cloth plow ...

AI Technical Summary

Problems solved by technology

[0003] In order to achieve wide-width paving, the above two types of paver have a relatively large span of the frame itself, and the frame is supported by two walking crawlers installed on both sides of the frame, and installed on both sides of the main frame during transition The walking track itself cannot turn, and the paver can only walk along the center line of its lateral width. However, due to the large lateral width of the paver and limited by the width of the road, most road paver cannot directly drive on it , Usually, the paver needs to be transported away by a large loading vehicle, which brings a lot of inconvenience to the construction unit

Therefore, it is necessary to develop a paver that can transfer by itself to solve the problem of inconvenient transfer during construction
