Inclined hoisting method of single hoisting point of steam drum

Abstract

The invention discloses a method and device for hoisting a steam pocket in a single hoisting point inclination manner. The device for hoisting the steam pocket comprises a beam, a support pillar, a winding engine, a cable and a pulley group, wherein the pulley group comprises a first fixed pulley, a second fixed pulley and a moving pulley. The method for hoisting the steam pocket in an inclination manner is used for hoisting the steam pocket and comprises the following steps: firstly installing the hoisting device on an installing frame, checking and marking the steam pocket, and connecting the steam pocket and the hoisting device so as to lift to a certain height; adjusting the steam pocket to have a certain hoisting slant angle alpha; and starting the winding engine and lifting the steam pocket to the top of the installing frame, hoisting a steam pocket installing support through auxiliary hoisting equipment, calibrating an installing frame elevation datum point after the hoisting is finished, confirming the installing frame elevation datum point of the steam pocket, correcting and installing the steam pocket, and dismantling the hoisting device. The device and the method disclosed by the invention have the advantages that the work efficiency can be improved, the hoisting time is shortened, the hoisting security is improved, and the hoisting cost is reduced.

Description

technical field [0001] The invention relates to the field of hoisting, in particular to an oblique hoisting method for a single hoisting point of a steam drum. Background technique [0002] Known: the hoisting method of boiler steam drum that adopts at present mainly is to utilize tower crane or large-scale truck crane to carry out hoisting. To use a tower crane to hoist the steam drum, the tower crane must be built in the boiler site where the steam drum needs to be installed. The construction progress is slow, the cost is high, and the construction period is long. The use of truck cranes for hoisting can speed up the construction progress, but because of the truck cranes, the hoisting costs are expensive. At the same time, large-scale car hoisting is required, and the requirements for hoisting equipment are high. At the same time, the height of the truck crane is limited, and when the installation position of the steam drum is high, the truck crane cannot complete the ho...
