The track frame of the existing crawler crane shown in fig. 1 has a substantially rectangular cross section, that is, the upper end surface is a plane, and as the crawler crane works in a muddy place for a long time, a large amount of mud is often accumulated on the track frame, so that the track frame is not easy to clean during maintenance or overhaul. Meanwhile, the accumulation of silt influences the engagement of the track shoe to a certain extent, so that the abrasion of the track shoe is aggravated, and the service life of the track shoe is influenced to a certain extent. Meanwhile, the appearance aesthetic feeling of the whole vehicle is reduced due to the accumulation of the silt, and the sensory effect of the whole vehicle is influenced. Therefore, the track frame convenient for cleaning soil needs to be designed, so that abrasion to the track plate caused by sediment accumulation and the like is reduced, and the service life is prolonged.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Interpretation of related terms

The cross-sectional characteristic of the track frame refers to a shape of a cross-sectional projection of a cross section of the track frame body.

Example 1

As shown in fig. 4 to 6, the track frame convenient for cleaning soil comprises a driving seat 1 and a guiding seat 2 which are respectively fixed on the end parts of two sides of the track frame, a connecting piece 3 is fixed between the driving seat 1 and the guiding seat 2, a first stressed seat 4 and a second stressed seat 5 are sequentially and fixedly arranged on the connecting piece 3, and square holes are respectively arranged in the middle parts of the first stressed seat 4 and the second stressed seat 5.
