Problems solved by technology

[0002] During the construction of the dam, arc-shaped gates need to be installed on the flood gates, which requires the use of large-scale equipment for hoisting. The existing technology generally uses large-scale cranes for hoisting, but the hoisting of large-scale cranes has high requirements for the site, and the distance between the lifting points of heavy objects There are certain restrictions, and the space at the crest of a general dam is relatively narrow, so it is difficult to meet the site requirements for hoisting by a large crane. Low, and the hoisting of large cranes adopts single lifting point and long-distance hoisting, which has poor stability and potential safety hazards

Abstract

The invention discloses large radial gate lifting equipment comprising a bridge erecting machine provided with a loading and unloading channel, wherein the top of the bridge erecting machine is provided with a lifting trolley which a stretches across the loading and unloading channel and can move along the loading and unloading channel, the lifting trolley is provided with a winch, and the winch is arranged above the loading and unloading channel. The large radial gate lifting equipment disclosed by the invention can conveniently realize the lifting of a large radial gate of a dam; and the stability and safety of a lifting process are guaranteed. The invention also discloses a lifting method adopting the large radial gate.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a hoisting device and a hoisting method for a large arc gate used for a reservoir dam. Background technique [0002] During the construction of the dam, it is necessary to install arc gates on the flood gates, which requires the use of large-scale equipment for hoisting. The existing technology generally uses large-scale cranes for hoisting, but the hoisting of large-scale cranes has high requirements for the site, and the lifting point distance for heavy objects There are certain restrictions, and the space at the crest of a general dam is relatively narrow, so it is difficult to meet the site requirements for hoisting by a large crane. Low, and the hoisting of large cranes adopts single lifting point and long-distance hoisting, which has poor stability and poses safety hazards. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present inventio...
