Hydraulic hoisting, slipping and emplacing method and equipment for large scale press components

Abstract

The invention discloses a hydraulic hoisting, slipping and emplacing method and equipment for large scale press components, which have the advantages of simple structure, safety, reliability, recoverability and repeated use. The hydraulic hoisting, slipping and emplacing equipment comprises two main beams which are parallel to each other and horizontally arranged. Three upright posts are fixedly connected to the lower part of each main beam, a fundamental base connected with the ground is arranged at the bottom of each upright post, two hoisting beams parallel to each other are arranged above the two main beams, the two ends of each of the two hoisting beams are mounted on the upper end surfaces of the main beams through end beams, two lifting oil cylinders are arranged above each hoisting beam, each lifting oil cylinder is mounted on the upper end surface of the hoisting beam through the lifting oil cylinder base at bottom, at least one stranded wire is arranged in each lifting oil cylinder, and a first hydraulic crawl device is mounted among the ends of the end beams and the main beams.

Description

technical field [0001] The invention relates to a hoisting device and a hoisting method, in particular to a device and a method for lifting and sliding a large component into place. Background technique [0002] Large presses are strategic equipment related to national security and economic development, as well as basic equipment for electric power, aviation, military and other manufacturing industries. As a big manufacturing country, my country is imminent in building and introducing large-scale presses, no matter in terms of international political relations and national defense needs, or in terms of realizing the transformation from a big equipment manufacturing country to a powerful country. A powerful country in the field must equip its own large presses. [0003] On this basis, Wuxi Turbine Blade Co., Ltd. imported SPKA22400 clutch screw press from German SMS company, with a maximum striking force of 35,000 tons. It is currently the most powerful forging equipment in t...

Problems solved by technology

[0006] There are the following problems in the above three methods: 1) There are no extra-large cranes with a capacity of more than 1500 tons in China. 200 tons of masts, and a large number of lifting tools such as 20 tons of winches are needed in addition. The biggest problem of this method is that the safety performance is not good, and the winches, guide sliders and wind ropes are not easy to install and anchor; 3) The third method needs to make a The gantry crane with a lifting capacity of 400 tons and a span of 21m is expensive to manufacture, difficult to recycle, and is restricted by the production license of the crane
