Bogie frame for caterpillar type multifunctional paver walking system

Abstract

The invention discloses a bogie frame for a caterpillar type multifunctional paver walking system. The bogie frame for the caterpillar type multifunctional paver walking system comprises a first frame body arranged at the outer side of a side wall board at the right side of a rack of a paver, a second frame body arranged at the outer side of a side wall board at the left side of the rack of the paver and a connecting shaft sequentially penetrating through the side wall board at the right side, a scraper system and the side wall board at the left side. The front end of the first frame body and the front end of the second frame body are respectively hinged with a front girder of the rack. A first hinging hole is formed in the rear portion of the first frame body and a second hinging hole corresponding to the first hinging hole in position is formed in the rear portion of the second frame body. One end of the connecting shaft is hinged in the first hinging hole and the other end of the connecting shaft is hinged in the second hinging hole. The bogie frame is simple in structure, convenient to use, and capable of enabling transverse load and longitudinal load of a caterpillar in contact with the ground to be even, reducing factors of deformation of the rack due to the bogie frame, enabling a caterpillar board to be attached to the ground well and guaranteeing driving stability of the paver.

Description

technical field [0001] The invention relates to the field of paver, in particular to a trolley frame used for the walking system of a crawler-type multifunctional paver. Background technique [0002] The design of the frame of the paver is required to follow the principle of elastic deformation. Reasonable design of frame components can effectively control elastic deformation, avoid plastic deformation, overcome the destructive force of frame deformation on components, and increase the self-leveling ability of paver at the same time. The crawler walking device has a large grounding area, a small grounding specific pressure, good adhesion, strong climbing ability, small turning radius, and strong ability to cross ditches and pits, so the crawler walking system is often used on large paver. The trolley frame, as the basic component of the crawler walking mechanism, can be rigidly connected to the frame on the basis of ensuring the elastic frame. Using the elastic deformation...

Problems solved by technology

[0003] However, for multi-functional paver with a paving width greater than 14m, the weight of the machine itself is large, the fuselage is long, and the walking system will have an impact on the rigidity of the overall frame.

If the rigid connection between the trolley frame and the paver on the side wall is easy to cause deformation of the frame, it will be accompanied by phenomena such as deviation, stagnation, and tilting of the frame, and will also break the original stable structure of the elastic frame
