As shown in fig. 1-2, the present invention relates to an embodiment, specifically to a method for installing a turbine condenser, comprising the steps of:

firstly, a gap exists between a condenser foundation 2 and an air compressor cooler foundation 1, a vertical installation tool 4 is installed in the gap between the air compressor cooler foundation 1 and the condenser foundation 2, the upper end face of the vertical installation tool 4 is flush with the upper end faces of the air compressor cooler foundation 1 and the condenser foundation 2, so that the smoothness of a road transported to the condenser foundation 2 is ensured, the vertical installation tool 4 comprises a plurality of support legs and a cross beam arranged at the upper ends of the support legs, the length of the cross beam is matched with the width of the gap between the air compressor cooler foundation 1 and the condenser foundation 2, the vertical installation tool 4 is used for paving roads, and the gap between the air compressor cooler foundation 1 and the condenser foundation 2 is consistent or has small size difference under common conditions, so that the vertical installation tool 4 can be commonly used in different places;

in this embodiment, the vertical installation tool 4 may also be designed to have a height and width adjustable structure, for example, a vertical telescopic support leg and a horizontal telescopic beam are adopted, so that the universality of the vertical installation tool 4 can be increased.

Then, the condenser 8 is transported to the position right above the condenser foundation 2 through the vertical installation tool 4 by the transportation moving platform 3, the transportation moving platform 3 consists of a frame supporting plate and a plurality of roller mechanisms positioned at the lower end of the supporting plate, the rollers can be universal wheels or transportation tankers, the transportation moving platform 3 can be driven by self power or external force to perform multi-directional translation, the accurate and stable transportation of the condenser 8 is ensured, the bulge at the lower end of the condenser 8 is arranged on the frame supporting plate, a groove matched with the convex part at the lower end of the condenser 8 can be arranged on the frame supporting plate of the transportation moving platform 3, the position of the lower end of the condenser 8, which is only the convex part, can be used as a reliable stress point, the condenser 8 is deformed by using the jack at other positions, and the transportation of the condenser 8 is stable due to the structural design;

after condenser 8 transported to the right place, the both sides of installing frock 4 perpendicularly are provided with detachable support piece 5, detachable support piece 5's lower extreme be provided with at least one first jack 6, particularly, detachable support piece 5 preferably H shaped steel crossbeam, first jack 6 is all installed at its downside both ends, detachable support piece 5 contacts with condenser 8 as the atress part, owing to adopt the face contact of large-span, make condenser 8 and detachable support piece 5 contact position of atress can not take place to deform, will detach support piece 5 and condenser 8 through first jack 6 and jack up together like this, transport moving platform 3 this moment just separates with condenser 8, shift out transport moving platform 3 from one side of condenser basis 2 again, use the jack for the first time is in order to realize taking out of transport moving platform 3.

Secondly, using the jacks for the second time, arranging a plurality of second jacks 9 at the positions of the original transporting and moving platforms 3 on the upper side of the condenser foundation 2, namely the positions of the protruding parts at the lower ends of the condensers 8, jacking the condensers 8 through the second jacks 9, adjusting the elevation of the condensers 8, enabling the condensers 8 to be installed in a butt joint mode with the steam turbine 7 above, and enabling the detachable supporting piece 5 to be separated from the condensers 8 at the same time, so that the detachable supporting piece 5 and the first jacks 6 can be taken out together easily, and the detachable supporting piece 5 and the first jacks 6 can be reused;

after condenser 8 adjustment installation is accomplished, take out perpendicular installation frock 4 between air compressor machine cooler basis 1 and the condenser basis 2, will dismantle support piece 5, first jack 6, second jack 9 and transport moving platform 3 and concentrate and place, constitute the simple and easy built-up installation frock that can recycle, it is very convenient.

In order to improve the stability of the transportation moving platform 3 during transportation of the condenser 8, the upside of the vertical installation tooling 4 is laid with a backing plate 11 spanning the air compressor cooler foundation 1 and the condenser foundation 2, the backing plate 11 is a steel plate, the transportation moving platform 3 moves on the backing plate 11, and the requirement for the structure of the vertical installation tooling 4 can be reduced.

Simultaneously, the upside on condenser basis 2 often can be provided with a plurality of and reserve hole 10, in order to ensure that the haul road is unobstructed, does not set up the parallels on reserving hole 10, condenser basis 2 on be provided with the steel sheet that will reserve hole 10 and cover, the steel sheet height keeps unanimous with perpendicular installation frock.

Therefore, the invention utilizes the transportation mobile platform to transport the condenser to the condenser foundation, repeatedly uses the jack and skillfully utilizes the limited position capable of bearing force at the bottom of the condenser to realize the taking out of the transportation mobile platform and the detachable supporting piece, simultaneously satisfies the jacking and adjustment of the condenser, can repeatedly utilize the tools used in the method, solves the problems of vertical transportation and installation, is also suitable for the transportation work of other large-scale equipment in a limited space, greatly shortens the construction period, greatly improves the hoisting safety and achieves the purpose of rapidness and safety.
