Problems solved by technology

At present, crawler cranes with booms are used as auxiliary cranes. The crawler cranes in the past can only share the lifting weight of the main crane, and cannot support the heavy objects to walk smoothly, let alone follow the rotation of the bottom of the heavy objects.

Embodiment Construction

[0024] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-5 As shown, the crawler frame structure provided by the present invention includes a crawler frame 1, a rotating load-bearing beam 2, a support mechanism 3 and a support 4, wherein: the two sides of the crawler frame 1 are respectively fixedly connected with a connecting mechanism 11, and the two support 4 They are respectively connected with the connecting mechanisms 11 on both sides of the crawler frame 1 . A support mechanism 3 is provided on the top surface of each support 4 . The support mechanism 3 has a through hole, and the axes of the through holes on the two support mechanisms 3 coincide. The two ends of the rotating load-bearing beam 2 penetrate into the through holes of the two support mechanisms 3 and are rotatably connected with the support mechanisms 3 . The supporting mechanism ...

Abstract

The invention relates to a crawler frame structure. The crawler frame structure comprises a crawler frame, a rotating bearing beam, supporting mechanisms and supports. Two sides of the crawler frame are respectively provided with one support; the top face of each support is provided with one supporting mechanism; each supporting mechanism is provided with a through hole, and axial leads of the through holes in the two supporting mechanisms on the two sides of the crawler frame coincide with each other; two end portions of the rotating bearing beam penetrate into the through holes in the two supporting mechanisms and are connected with the supporting mechanisms in a rotating mode; the rotating bearing beam can rotate within the angle range of 0 degree to 90 degrees. The crawler frame structure can make a weight lifting process stable and make overall stress even.

Description

technical field [0001] The invention relates to a tail runner, in particular to a crawler frame structure on the tail runner. Background technique [0002] With the development of national construction, the quality, volume and lifting height of heavy objects that need to be lifted are constantly increasing. Cranes with crawler chassis are more and more widely used because of their advantages such as small grounding pressure and the ability to carry loads. The working conditions that crawler cranes need to adapt to are becoming more and more diverse. When hoisting large vertical heavy objects, a kind of auxiliary crane is needed, which supports the bottom of the heavy object to walk when hoisting, and a crawler frame structure that rotates with the rotation of the heavy object during the upright process of the heavy object. At present, crawler cranes with booms are used as auxiliary cranes. The crawler cranes in the past can only share the lifting weight of the main crane, a...
