Combined counterweight structure and crawler crane with same

Abstract

The invention discloses a combined counterweight structure. The combined counterweight structure comprises a first counter mechanism and second counter mechanisms, wherein the first counter mechanismis fixedly arranged at the tail part of a rotary table, the second counter mechanisms are detachably arranged on the left side and the right side of the rotary table, the first counter mechanism comprises trays fixed at the tail part of the rotary table and first counter blocks arranged on the trays; the second counter mechanisms comprises detachable counter blocks, the counter blocks comprises extension parts and counterweight parts, the counter blocks comprises second counter blocks and third counter blocks, the third counter blocks are hung on the second counter blocks. The invention discloses a crawler crane with the combined counterweight structure. According to the combined counterweight structure, the space at the tail part of the rotary table is fully utilized, so that the stress of the tail part of the rotary table is more uniform, the stability of rotation, traveling and weight of the whole crane can be guaranteed, under the condition that the counterweight is not disassembled, the width of the whole crane is effectively reduced, the walking trafficability of the whole crane on a narrow road surface is improved, disassembling and assembling of components such as the counterweight and a boom are reduced, the convenience of short-distance transferring is greatly improved, the rotating field efficiency is greatly improved, and the use cost is reduced.

Description

technical field [0001] The invention relates to a combined balance weight structure, in particular to a combined balance weight structure and a crawler crane thereof, belonging to the technical field of engineering machinery. Background technique [0002] Crawler cranes are a relatively important type of mechanical equipment in construction machinery and equipment, and play an important role in infrastructure construction, wind power construction, nuclear power construction, and petrochemical construction. As an important part of the crawler crane, the counterweight has an important influence on the stability and lifting performance of the whole vehicle. When the crawler crane for wind power is used for the installation and construction of wind power equipment, the road surface for short-distance transition is relatively narrow, and there is a high requirement for the width of the whole machine when walking without dismantling the counterweight. [0003] Due to the large si...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the disadvantages that the combined counterweight mechanism in the prior art cannot walk on narrow roads, the counterweight is difficult to disassemble, and the center of gravity of the main engine shifts after the counterweight is removed, and provides a combined counterweight structure. The technical solution is as follows:
