Auxiliary supporting device for paver

Abstract

The invention discloses an auxiliary supporting device for a paver. The auxiliary supporting device comprises a rack of the paver, and two supporting assemblies which are arranged at the two ends of the rack in pairs and are same in structure. The supporting assembly comprises a fixed arm, a rotary arm, a telescopic arm and a wheel set, wherein the fixed arm is fixed to the rack, the rotary arm ishinged to the fixed arm, the telescopic arm is hinged to the rotary arm, and the wheel set is installed on the telescopic arm; a telescopic element II is hinged between the fixed arm and the rotary arm, and the telescopic element II changes the length of itself by stretching and retracting to enable the rotary arm to rotate around the fixed arm; and a telescopic element I is hinged between the rotating arm and the telescopic arm, and the telescopic element I enables the telescopic arm to rotate around the rotating arm by changing the length of the telescopic element I through stretching. Theauxiliary supporting device is simple and compact in structure, not only has an auxiliary supporting function, but also has a hoisting function, and effectively solves the gravity center problem of the paver and the hoisting installation problem of related parts.

Description

technical field [0001] The invention relates to an auxiliary supporting device for a paver, which is suitable for a paver with a rear center of gravity and a need for auxiliary hoisting, especially for a large-scale paver with an ultra-wide working condition. Background technique [0002] In recent years, with the continuous development of road construction, pavers have gradually developed in the direction of large width, large thickness, and multi-function. In order to meet the ever-increasing width requirements of the paver screed, the ensuing problem is that the center of gravity of the entire paver is constantly moving backwards, and even the head of the paver may warp when it is transferred. Due to the space limitation of the fuselage, the conventional method of adding counterweight cannot effectively solve this problem. In addition, there are many accessories of the paver and most of them are relatively heavy, especially the extension sections of the screed, which urg...

Problems solved by technology

Due to the space limitation of the fuselage, the conventional method of adding counterweight cannot effectively solve this problem

In addition, there are many accessories of the paver and most of them are relatively heavy, especially the extended sections of the screed, which urgently need hoisting and lifting equipment to assist in the installation process.
