Special device for placing No.8 and No.9 high-pressure heaters of high-position-arranged steam turbine in place

Abstract

The invention discloses a special device for placing No.8 and No.9 high-pressure heaters of a high-position-arranged steam turbine in place, and belongs to the technical field of thermal power plants of electric power systems. A low-pressure heater foundation is arranged on the ground, a foundation portal frame is arranged on the low-pressure heater foundation, a hauling track is arranged on the foundation portal frame, a heater is in sliding fit with the hauling track, and the effect is that during use, two cranes are matched for hoisting, equipment is hoisted to an in-place height by the single main crane, and the auxiliary crane is matched with the main crane for hook replacement. After the hook replacement is completed, a winch arranged in a factory building is matched with the main crane to drag the heater to the low-pressure heater foundation along the hauling track, or after the equipment is hoisted to the in-place height through the single main crane, a traveling crane and the main crane are used for hoisting in place, and installation of the special device for placing the No.8 and No.9 high-pressure heaters of the steam turbine in place is realized. The technical purpose of hoisting large equipment for high-position equipment in the prior art is achieved.

Description

technical field [0001] The invention relates to the technical field of electric power system thermal power plants, in particular to a special device for installing No. 8 and No. 9 steam turbines at high positions. Background technique [0002] The high-level layout scheme has the advantages of shortening the length of the pipeline, reducing the coal consumption of power supply, and improving the thermal efficiency of the unit. The high-level arrangement of steam turbines has also caused chain changes in equipment arrangement, pipeline arrangement, structural design, and seismic design. The heat recovery system adopts a 9-level heat recovery system. Compared with the early 7-level heat recovery system, a combined low-pressure heater No. 8 / 9 is added, and the exhaust device that is conventionally arranged on the 0-meter floor is also increased to the 43-meter floor. . [0003] No. 8 / 9 of this project has a low weight of 71 tons and a length of 19 meters. It is arranged betwe...
