Hoisting and flipping tooling for high-pressure heater piping system

Abstract

The invention discloses a hoisting and overturning tool of a high-pressure heater pipe system. The hoisting and overturning tool comprises two header supports, at least one jacketing support and an overturning device; each header support comprises a first supporting ring, a first annular groove with whelps at the bottom is formed in the outer circle of each first supporting ring, positioning sleeve covers are arranged on the upper side and the outer side of the inner circle of each first supporting ring, and each first supporting ring is formed by oppositely splicing a first left semi ring and a first right semi ring; the jacketing support comprises a second supporting ring, a second annular groove with whelps at the bottom is formed in the outer circle of the second supporting ring, positioning supporting frames are arranged on the upper side, the outer side, the left side and the right side of the inner circle of the second supporting ring, and the second supporting ring is formed by oppositely splicing a second left semi ring and a second right semi ring; and the overturning device comprises a band and beam, a transverse rod is arranged at the lower portion of the band and beam, one end of the band and beam is provided with a gear motor, and a plurality of chain wheels are arranged on the transverse rod. By means of the above hoisting and overturning tool, the pipe system can be conveniently hoisted and overturned, and the pipe system is not prone to occurring deformation damage during hoisting and overturning.

Description

technical field [0001] The invention relates to the field of production tooling for high-pressure heaters, in particular to the hoisting and flipping tooling for piping systems of high-pressure heaters. Background technique [0002] A high-pressure heater is a device that can use high-temperature steam from a steam turbine to heat water. The high-pressure heater mainly includes the cylinder and the piping system used for heat exchange in the cylinder. The piping system needs to be manufactured outside the cylinder and turned 90 degrees before it can be sent into the cylinder for installation. The structure of the piping system includes: For the tube bundle composed of heat pipes, on the outer surface of the tube bundle, there are several ring-shaped supporting accessories that can support and position the tube bundle along the tube bundle. The tank shell, and the two ends of each heat exchange tube in the tube bundle are respectively connected with the side walls of the hea...
