Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0028] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the present invention has a multi-degree-of-freedom crawler counterweight trolley synchronous structure, including a bearing device for carrying the counterweight and a plurality of counterweight objects 2, wherein the bearing device mainly consists of two independent car bodies 10 arranged side by side. Each car body 10 includes a crawler-type traveling mechanism 11, and the crawler-type traveling mechanism 11 is connected to the lower part of the car body 10 through a slewing support component 12, and a rigid connection is formed between the two car bodies 10 through a connecting frame 13. The connecting frame 13 The middle part is connected with the rear part of the main engine 4 through a connecting part, ...

The invention discloses a multivariant synchronous structure of a crawler-type counterweight trolley, which comprises a bearing device for bearing counterweights and a plurality of counterweights, wherein the bearing device is mainly formed by two independent vehicle bodies which are arranged in parallel, each vehicle body comprises a crawler-type travelling mechanism, the crawler-type travelling mechanisms are connected with the lower parts of the vehicle bodies through slewing bearing parts, the two vehicle bodies form rigid connection through a connection frame, the middle part of the connection frame is connected with the rear part of a host machine through a connection part, and the counterweights are respectively arranged on the two vehicle bodies according to a preset proportion.
Description
technical field [0001] The invention relates to a counterweight structure of a crawler crane, in particular to a synchronous structure of a crawler counterweight trolley with multiple degrees of freedom and a crane including the structure. Background technique [0002] The superlift counterweight trolley is mainly used in large-tonnage crawler cranes and all-terrain cranes. It cooperates with the superlift device to increase the stability of the boom, give full play to the performance of the crane jib, and expand the scope of application of the crane. [0003] Existing large-tonnage crawler crane superlift counterweight trolley generally adopts crawler type or tire type walking mechanism, and the connection scheme between the main engine and the trolley basically adopts rigid connection. Compared with the crawler-type walking scheme, the tire-type structure is complex, expensive and has a great loss. At the same time, the rigid connection has extremely high requirements on ...
