Embodiment 1

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

[0048] According to the designed overweight horizontal high-pressure heater 13 hoisting and in-position plan, complete the installation of hauling slides, traction facilities and the arrangement of two hoisting machines, and determine the overweight horizontal high-pressure heater before the overweight horizontal high-pressure heater 13 enters the site. The loading direction of the heater 13 should be consistent with the plan. After the overweight horizontal high-pressure heater 13, park the transport truck to the unloading position, and use a 600-ton crawler crane and a 450-ton crawler crane to lift the unloading truck; for the convenience of equipment transportation, the manufacturer will The overweight horizontal high-pressure heater 13 arrives at an angle. After unloading, the high-pressure heater needs to be turned around. A 600-...

Abstract

The invention relates to a hoisting system and hoisting method for an overweight horizontal high-pressure heater, comprising a first crawler crane, a second crawler crane, and a hauling slide; the main arms of the first crawler crane and the second crawler crane rotate Coverage partially overlaps, the hauling chute is located outside the longitudinal area where the first crawler crane and the second crawler crane are located, close to the first crawler crane, and in the transverse direction, the first crawler crane is compared to the second crawler crane The distance between the crane and the hauling chute is 3500‑4500mm short, and the objects to be hoisted enter from the edge of the area covered by the second crawler crane and the side close to the first crawler crane, the central axis of the hauling chute is perpendicular to the longitudinal direction, The starting point of material entry and the hauling slideway are respectively located on both sides of the first crawler crane. It realizes the hoisting and positioning of relatively heavy and large-scale equipment such as 320-ton equipment, and the equipment can be rotated 90 degrees.

Description

technical field [0001] The invention belongs to the technical field of metal material preparation, and particularly relates to a hoisting system and a hoisting method for an overweight horizontal high-pressure heater. Background technique [0002] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] High-pressure heaters are heavy equipment in power plants. At present, a single horizontal high-pressure heater of one million steam turbine generator sets weighs about 190 tons. The high-voltage heater of the million-turbine-generator unit of this project is horizontal, and the maximum weight of a single unit is 320 tons. [0004] The hoisting and positioning of the large-scale horizontal high-pressure heate...
