Counterweight balance equipment of crane

Abstract

The invention discloses counterweight balance equipment of a crane. The counterweight balance equipment comprises balance blocks, rate pulley blocks, guide pulley blocks and steel wire ropes, wherein the balance blocks are arranged behind a trolley; the rate pulley blocks are arranged on a cross beam and the balance block; the guide pulley blocks are arranged on the trolley and a lifting tool mechanism; the two ends of each steel wire rope are fixed in front of or behind the trolley; the steel wire ropes move round the guide pulley blocks on the trolley and the lifting tool mechanism and the rate pulley blocks on the cross beam and the balance block, and are used for connecting the trolley, the lifting tool mechanism and the balance blocks in series; the balance blocks and the lifting tool mechanism make a reverse movement under the traction action of the steel wire ropes; the balance blocks moves along guide brackets and are provided with balance block fixing devices. The counterweight balance equipment is especially suitable for large or ultra-large container bank cranes and container yard rail-mounted gantry cranes with lifting tool mechanisms with larger self weight.

Description

technical field [0001] The invention relates to the field of cranes, and more specifically relates to a counterweight balancing device of a crane. Background technique [0002] In order to adapt to the rapid development of container transportation, terminals around the world generally purchase large and efficient shore-to-shore container cranes (hereinafter referred to as quayside cranes) to maximize loading and unloading efficiency, reduce ship berthing time, and meet the requirements of large-scale ships. However, the large installed capacity of super-large quay cranes has led to increased energy consumption in operation. Facing the trend of rising global energy prices, terminal profits have declined instead, and it does not conform to the concept of "low carbon and environmental protection" advocated by the world and my country's "12th Five-Year Plan" Energy saving planning requirements. [0003] In addition, due to the large number of gantry cranes in the container yard,...
