Embodiment 1

[0047] Object to be hung (overweight horizontal equipment) is an overweight horizontal high-pressure heater 13 with a weight of 320 tons.

[0048] According to the hoisting and positioning scheme of the super-heavy horizontal high-pressure heater 13 designed, the installation of the haulage chute and traction facilities and the arrangement of the two hoisting machines are completed, and the super-heavy horizontal high-pressure heater 13 is determined before entering the site. The loading direction of the heater 13 should be consistent with the plan. After the overweight horizontal high-pressure heater 13, stop the transport vehicle to the unloading position, and use a 600-ton crawler crane and a 450-ton crawler crane to lift and unload the truck; for the convenience of equipment transportation, the manufacturer will The super-heavy horizontal high-pressure heater 13 arrives obliquely. After unloading, the high-pressure heater needs to be turned around. A 600-ton crawler crane a...

Abstract

The invention relates to an overweight horizontal high-pressure heater hoisting system and hoisting method. The overweight horizontal high-pressure heater hoisting system comprises a first crawler crane, a second crawler crane and a hauling slide way; the main arm rotating coverage ranges of the first crawler crane and the second crawler crane are partially overlapped, and the hauling sliding wayis located on the outer side of the longitudinal area where the first crawler crane and the second crawler crane are located and is close to the first crawler crane in the transverse direction; the distance between the first crawler crane and the hauling slide way is 3500mm-4500 mm shorter than that between the second crawler crane and the hauling slide way, a to-be-hoisted object enters from theedge of the coverage area of the second crawler crane and one side close to the first crawler crane, and the central axis of the hauling slide way is perpendicular to the longitudinal direction, and the starting point of the to-be-hoisted object and the hauling slide way are positioned on two sides of the first crawler crane respectively. Hoisting in place of large and heavy equipment such as 320-ton equipment is achieved, and the equipment can rotate by 90 degrees.

Description

technical field [0001] The invention belongs to the technical field of metal material preparation, and in particular relates to an overweight horizontal high-pressure heater hoisting system and hoisting method. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] High-pressure heaters are heavy equipment in power plants. At present, a single horizontal high-pressure heater for a million-turbine generator set weighs about 190 tons at most. The high-pressure heaters of the million turbo-generator units in this project are horizontal, and the maximum weight of a single unit is 320 tons. [0004] The hoisting and positioning work of the large horizontal high-pressure heater is ca...
