Crawler crane and deformation method thereof

Abstract

The invention discloses a crawler crane and a deformation method thereof. The crawler crane comprises a cargo boom, a superlift mast, a crawler beam, a frame, a slewing bearing, a rotary table, a superlift counterweight and a pull plate, the track beam comprises a left track and a right track, and the left track and the right track are both sectional tracks; the frame comprises a center support and side supports, the two sides of the center support are connected with side support sets formed by sequentially and detachably connecting a plurality of side supports end to end, the two ends of each side support set are connected with the crawler beams or the other side support set, and the other side support set is connected with the crawler beams. The central bracket is connected with the slewing bearing; the bottom of the rotary table is rotationally connected with the slewing bearing, and the rotary table is provided with at least one group of first connecting parts connected with the cargo boom and second connecting parts connected with the superlift mast; and each group of superlift masts is connected with a superlift counterweight through a pull plate. The method has the advantages of improving the modularization and generalization level of parts of manufacturers, facilitating production organization management, shortening the research and development period and increasing the profitability of customers.

Description

technical field [0001] The invention relates to a crawler crane and a deformation method thereof, belonging to the technical field of construction machinery. Background technique [0002] With the rapid development of petrochemical, electric power and other industries, the trend of large-scale hoisting is becoming more and more obvious. However, in practical applications, there are not too many super-large tonnage hoisting parts on a construction site, and most of them are small and medium-tonnage hoisting. If a super-large tonnage crawler crane is used for construction , resulting in waste, and at the same time as the construction progresses, the construction area of ​​the construction site is getting smaller and smaller, and the construction scope of the super tonnage crawler crane is limited. In this case, if a crawler crane is configured according to the working conditions, at least multiple types of crawler cranes are required to cover the hoisting of the heaviest parts...

[0002] With the rapid development of petrochemical, electric power and other industries, the trend of large-scale hoisting is becoming more and more obvious. However, in practical applications, there are not too many super-large-tonnage hoisting parts on a construction site, and most of them are small and medium-sized tonnage hoisting. If super-large-tonnage crawler cranes are used for construction , resulting in waste. At the same time, as the construction progresses, the construction area of ​​the construction site is getting smaller and smaller, and the construction scope of super-large tonnage crawler cranes is limited.

In this case, if the crawler cranes are configured according to the working conditions, at least multiple types of crawler cranes are required to cover the lifting of the heaviest parts and the lifting of ordinary parts, resulting in an increase in the idle rate of equipment and an increase in the purchase and use costs of crane users.
