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...

Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] Such as Figure 1 to Figure 3 As shown, a construction machinery chassis connection structure includes a longitudinal beam 1 and an H frame 2, and also includes an H frame bending connecting plate 201 and an H frame horizontal connecting plate 202 for connecting the H frame 2 to the longitudinal beam 1, and the H frame The frame bending connecting plate 201 and the H frame horizontal connecting plate 202 are welded to form a Z-shaped structure; the H frame bending connecting plate 201 is used as the Z-shaped horizontal folding upper part and the H frame horizontal connecting plate 202 as the Z-shaped horizontal bottom edge The welding is in a Z-shaped structure; the H frame bending connecting plate 201 is welded under one end of the H frame 2; the H frame 2 is fixedly connected with the longitudinal beam top plate 101 of the longitudinal beam 1 through the H frame be...
