Problems solved by technology

Although this structure is detachable, there are the following problems: First, because the size of the H-frame structure is limited by the height of the chassis of the whole machine, its structural strength and rigidity are difficult to be guaranteed. This phenomenon is especially obvious in large-scale construction machinery
Secondly, due to this connection form, only the upper plane of the longitudinal beam and the H-frame cooperate to carry the load, the load-bearing structure is relatively simple, and it is easy to cause stress concentration at the connection part, the load-bearing capacity is limited, and the reliability and stability are not strong.
[0004] In addition to the lap connection method, there are also some construction machinery chassis where the H-frame is inserted into the longitudinal beam. This type of connection will greatly weaken the structural strength of the longitudinal beam, and the application range is limited. Where the load is severe

Abstract

The invention discloses a construction machinery chassis connection structure, which comprises an H frame, a longitudinal beam, an H frame bending connecting plate and an H frame horizontal connecting plate for connecting the H frame and the longitudinal beam, and the H frame bending connecting plate and the H frame The horizontal connecting plate is welded in a Z-shaped structure; the bent connecting plate of the H frame is welded under one end of the H frame; The frame horizontal connecting plate is fixedly connected with the longitudinal beam bottom plate of the longitudinal beam in the horizontal direction. In the present invention, the connection between the H frame and the longitudinal beam is composed of the top surface and the side surface. The three-dimensional connection structure bears evenly, and stress concentration is not easy to occur. The structural strength of the connection is greatly enhanced, and the connection reliability is high; The H frame provides sufficient structural space to ensure that the H frame has sufficient structural strength; the structure is simple, and the connection form is mainly embodied by a bent plate, which reduces the welding structure and welding cost.

Description

technical field [0001] The invention relates to a connection structure, in particular to a construction machinery chassis connection structure, which belongs to the technical field of construction machinery. Background technique [0002] At present, the construction machinery chassis, especially the crawler type construction machinery chassis, generally consists of three parts: the H frame placed in the middle for connecting the boarding vehicle and the longitudinal beams on the left and right sides used to arrange the walking system. For the chassis of large-scale construction machinery, due to its large dead weight and large lateral peripheral dimensions, it is not convenient for overall transportation, so a detachable chassis is required. [0003] In the existing detachable construction machinery chassis, the main form is that the H frame is lapped on the longitudinal beam. The H frame of this structure is completely placed on the top surface of the longitudinal beam, and...
