Problems solved by technology

[0003] The upper and lower bodies of most crawler cranes are connected by rotating rollers and bolts. Generally, the diameters of rollers and bolts are limited, and their ability to bear radial loads directly affects the lifting capacity, that is, the tonnage level of the crane is limited.
At present, the connection support form of the rotary roller structure has a bottleneck, which cannot meet the design requirements of larger cranes

Embodiment Construction

[0014] The wheel-set supporting trolley device of the super large crawler crane includes a combined trolley mechanism 2, a driving mechanism 4 and a hook roller mechanism 1. The combined trolley mechanism 2 is composed of a multi-stage beam frame hinged step by step and a wheel set 10 at the bottom. The driving mechanism 4 and The hook roller mechanism 1 is respectively connected to the combined trolley mechanism 2; the wheel set 10 at the lower part of the trolley device is adapted to the circular track 17 on the lowering base 5, and the upper part of the trolley device is connected and fixed to the upper platform 3 to form a support. The combined trolley mechanism 2 is hinged on the two ends of the first-level beam frame 9 with two second-level beam frames 13 respectively, and the two ends of the second-level beam frame 13 are hinged with two third-level beam frames 11 respectively, and each three-level beam frame 11 There are two wheels below, and the eight wheels under the f...

Abstract

The invention relates to an ultra-large type crawler crane wheel set type bearing trolley device which is suitable for slewing bearing of an ultra-large type crawler crane. The device is assembled between a base and a platform. The trolley device mainly comprises a combination trolley mechanism, a driving mechanism and a hook roller mechanism. The combination trolley mechanism is composed of multiple stages of beam frames which are hinged step-by-step and wheel sets at the bottom of the mechanism, and the driving mechanism and the hook roller mechanism are respectively connected to the combination trolley mechanism. The wheel sets on the lower portion of the trolley device are matched with an annular track on a lower trolley base, the upper portion of the trolley device is fixedly connected with an upper trolley platform, and bearing is formed. The ultra-large type crawler crane wheel set type bearing trolley device integrates driving, rotating and bearing, limitation of bearing radius factors in the crane design is avoided, the anti-tipping-over capability is improved, due to the upper trolley and lower trolley bearing mode of the trolley device, larger loads can be borne, and the working condition of large load moment and the large working radius is facilitated.

Description

[0001] 1. Technical Field [0002] The invention relates to a slewing support mechanism of a crawler crane, in particular to a slewing trolley device used for connecting and supporting the loading and unloading of a large tonnage crawler crane. 2. Background technology [0003] The upper and lower bodies of most crawler cranes are connected by slewing rollers and bolts. Generally, the diameters of rollers and bolts are limited, and their ability to withstand radial loads directly affects the lifting capacity, that is, the tonnage level of the crane is limited. At present, the connection support form of the slewing roller structure has bottlenecked, which cannot meet the design requirements of larger cranes. The wheel-type supporting trolley device breaks through the limitation of the bearing radius, greatly enhancing its ability to withstand bending moments, and its anti-rolling ability is also significantly improved. In other words, the trolley device is a breakthrough to break ...
