Problems solved by technology

[0005] However, with the continuous improvement of the load-carrying capacity of the crawler chassis, the structure of the existing variable-gauge crawler chassis is bound to have the problem of poor working stability
Taking a large-tonnage crane as an example, under the condition of extreme working load or improper operation method, the overturning moment will lead to a large structural stress at the connection part between the underframe and the crawler frame, resulting in destructive accidents such as plastic deformation or even fracture.
Therefore, there are problems of poor local structural rigidity and poor working stability of the whole machine.

Embodiment Construction

[0031] The present invention improves the design based on the existing crawler chassis. The core of the scheme is that the chassis adopts a split structure between the connecting beams on the front and rear sides, and the connecting beams respectively have attachments extending toward the chassis. seat to reliably connect the fixed connection relationship between the crossbeam and the underframe; the length of the attached seat is designed according to the task requirements, thereby ensuring that the distance between the front and rear beams on each side of the underframe and the track frame meets the working stability requirements Require.

[0032] The present embodiment will be described in detail below in conjunction with the accompanying drawings.

[0033] The orientation words such as front, rear, left, and right involved in this article are defined based on the traveling direction of the crawler chassis. It should be understood that the use of the orientation words shoul...

Abstract

The invention discloses a crawler chassis which comprises an underframe, two crawler frames and two connecting crossbeams, wherein the two crawler frames are symmetrically arranged at the right side and the left side of the underframe; the two connecting crossbeams are symmetrically arranged at the front side and the rear side of the underframe; the ends of the right side and the left side of the two connecting crossbeams are respectively connected with the crawler frames at the right side and the left side; the front connecting crossbeam is provided with an auxiliary seat extending backward, and the rear connecting crossbeam is provided with an auxiliary seat extending forward; and the auxiliary seats on the two connecting crossbeams are detachably and fixedly connected with the underframe. The crawler chassis meets the design requirements through the length of the auxiliary seats and can meet the requirement of external size for transportation while guaranteeing working stability, thereby greatly improving the stress conditions of all parts of the crawler chassis and enhancing the rigidity of the chassis. In addition, the external size and the weight of the underframe are effectively reduced to further facilitate transportation and installation of a whole machine. On the basis, the invention also discloses a crawler crane with the chassis.

Description

technical field [0001] The invention relates to a walking chassis of construction machinery, in particular to a crawler chassis and construction machinery with the chassis. Background technique [0002] The crawler chassis has the characteristics of large ground contact area, good passability and strong adaptability, and can walk with a load, so it has been widely used in various construction machinery. [0003] The traditional crawler chassis mainly includes two main parts, the underframe and the track frame. As an intermediate connecting part, the underframe is used to carry the upper vehicle and bear the force transmitted by each component. The connection between the underframe and the track frame is realized by inserting the beam fixed on it into the track frame. In order to meet the requirements of different purposes and transportation, most of the crawler chassis used on existing construction machinery have the function of changing the track gauge. See figure 1 , wh...
