Problems solved by technology

Compared with the crawler-type walking scheme, the tire-type structure is complex, expensive and wears a lot
At the same time, the rigid connection has extremely high requirements on the mechanical properties of the connecting mechanism between the trolley and the main engine, and it is not convenient for the superlift counterweight trolley to walk synchronously with the crawler crane, and it is not conducive to adjusting the offset of the superlift counterweight, and there is a superlift counterweight Hazard of tipping over

Embodiment Construction

[0027] The following combined with the attachment and the specific embodiments further explained the present invention, but it is not limited to the present invention.

[0028] like figure 1 As well as figure 2 As well as image 3 As well as Figure 4 and Figure 5 It shows that the present invention has a curivocated heavy car synchronization structure, including the bearing device and multiple heavy weights 2 for carrying weight. Among themFormed, each car body 10 includes a crawler walking mechanism 11, a crawler walking mechanism 11 to connect to the lower part of the car body 10 through the turn support component 12.The central part is connected to the rear of the host 4 through one connection component, and the weight 2 is placed on the two car body 10 according to the preset ratio.

[0029] The principle of the present invention is that the tracked walking mechanism below the two car body 11 can turn around through the turn support component 12, so that the structure provided ...

Abstract

The invention discloses a synchronous structure of crawler counterweight trolleys with multiple degrees of freedom, including a bearing device for bearing counterweights and a plurality of counterweight objects, wherein the bearing device mainly consists of two independent trolleys arranged side by side Each of the car bodies includes a crawler-type traveling mechanism, and the crawler-type traveling mechanism is connected to the lower part of the car body through a slewing support component, and a rigid connection is formed between the two car bodies through a connecting frame. The middle part of the connecting frame is connected to the rear part of the main engine through a connecting part, and the counterweights are respectively placed on the two car bodies according to a preset ratio.

Description

Technical field [0001] The invention involves the heavy structure of a crawler crane, especially a crawler -heavy car synchronization structure with a multi -freedom and a crane synchronization structure and a crane including the structure. Background technique [0002] Speed heavy -duty cars are mainly used in large tonnage crawle cranes and all -ground cranes. It and the over -lifting device cooperate with the stability of the boom, give full play to the performance of the litter arm frame, and have expanded the scope of applicable to the crane. [0003] The existing large tonnage crawler crane is generally used in a track or tire walking mechanism. The connection scheme between the host and the car basically adopts rigid connection.Compared to the tracking scheme, the tire -type structure is complex, the price is expensive and the loss is extremely large.At the same time, the rigid connection has high mechanical performance requirements for the connection mechanism between the...
