Balance weight fastening and hoisting device and crawler crane with same

Abstract

The invention discloses a balance weight fastening and hoisting device which comprises fasteners for being connected with balance weights. Connecting holes matched with the balance weights are formedin the fasteners, and the fasteners are fixedly connected with the balance weights. Hoisting parts are arranged at the tops of the fasteners. The balance weights are in two sets, the fasteners are symmetrically arranged on the two sets of balance weights, and the fasteners are arranged on the side faces of the balance weights. The invention further discloses a crawler crane with the balance weightfastening and hoisting device. The balance weight fastening and hoisting device enables the balance weights to be more effectively connected into a whole, reduces the risk of overturning caused by dislocation among the balance weights due to shaking, and is safer and more reliable. After the balance weights are assembled on a deck, the whole balance weights are mounted on a main machine through one-time hoisting by means of hoisting holes of the fasteners, potential safety hazards that the balance weights are unstably installed due to sea surface shaking when the balance weights are sequentially mounted on the main machine are avoided, and meanwhile the balance weights can be integrally hoisted, so that the hoisting efficiency of the balance weights is improved.

Description

technical field [0001] The invention relates to a counterweight fastening and hoisting device, in particular to a counterweight fastening and hoisting device and a crawler crane thereof, belonging to the technical field of engineering machinery. Background technique [0002] Crawler cranes are an important category of 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 is used for offshore operations, the working conditions are even harsher, and higher requirements are placed on the safety and reliability of the fastening and hoisting of the counterweight. The existing product uses a fastening chain to pass through the middle hole of the balance weight, the top and bottom of ...

AI Technical Summary

Problems solved by technology

[0003] In the case of a flat ground with a small slope, the use of chain fastening can ensure the safe and stable use of the counterweight. However, when the crawler crane is used on a sea ship, the hull is subjected to the impact of waves. In severe cases, the hull shakes violently, and even the inclination angle exceeds The use of cranes on land is required. At this time, the effect of fastening the chain to fasten the balance weight is poor, and the balance weight is easy to misalign and tip over, causing safety hazards
