Description

The invention relates to the field of construction and can be used in the construction of multi-unit thermal power plants.

The purpose of the invention is to reduce material consumption, installation time and operating costs.

In FIG. 1 shows a plan of a thermal power plant: in FIG. 2 is a section 1-1 in FIG. 1; in FIG. 3 is a section 2-2 in FIG. 1; In FIG. 4 - node I in FIG. 3 in FIG. 5 - moving the platform under the generator; in FIG. 6 - moving the generator on the platform; in FIG. 7 is a section BB of FIG. 5, in FIG. 8 - node II in FIG. 7; in FIG. 9 - node III in FIG. 1.

The power plant includes power units 1 installed in parallel to each other, each of which includes a gas turbine unit 2 and an alternating current generator 3 mounted on a support frame 4 and an air intake 5 with air ducts 6 to the gas turbine unit 2. The power unit 1 is mounted on the base 7 and connected by a gas duct 8 s chimney 9.

Each of the power units 1 is located in a separate main box 10 of two channels 11, 12, in the upper 12 of which an air collector 5 is installed. Section 11 is made at the end of the opening 13 with a removable or opening cover 14, which is mounted with the possibility of displacement, by 00

For example, by pulling to the air intake section 12, in addition, at the end 13 of the box 10, a contour docking element 15 is installed, for example, in the form of a channel 16.

The auxiliary box 17 is configured to dock to the contour docking element 15 of the box 10 by means of a contour connecting element 18 with a seal 19 on the bolts 20.

The power unit 1 is installed on the base 21 by means of a support frame 4, which is made up of a generator 22 and a turbine 23 parts, which are interconnected with a connector, for example, on the bolts 20. Each part of the frame 4 includes contour elements 24 and connecting beams 25, on which intermediate supporting nodes 26 are placed. The bases 21 are made with a longitudinal through channel 27 and walls 28 on which the frames 4 are installed with the formation of openings 29 under the power unit 1.

The hoisting-and-transport device of the station is made in the form of a platform 30 which includes longitudinal 31 and transverse beams 32, is mounted on swivel trolleys 33 and is equipped with jacks 34, different located respectively intermediate intermediate nodes 26.

The tracks are installed in two mutually perpendicular directions, with the longitudinal path 35 placed along the boxes 10, and the transverse paths 36 installed along the longitudinal axes of the power units 1, brought into the openings 29 of the channels 27 under the support frame 4 and intersect the longitudinal paths 35. In places intersections of paths 35 and 36 mounted rotary cells 37.

The drive for moving the platform 30 is made in the form of winches 38 with a cable 39, a retractable roller 40 and a gripping mechanism 41. the winches 38 and the retractable rollers 40 are mounted on additional bases 42, which are placed separately for the longitudinal 35 and each transverse 36 ways. In addition to the winch 38 for the longitudinal path 35, the station also has at least one winch 38 for moving along the transverse path 36, which is installed on the path on which the platform 30 is located.

The claimed device operates as follows. The power unit 1 installed in a separate main box 10 operates independently of the neighboring ones and upon failure of one of the units, the operating conditions of the others do not change. In the event of a failure, for example, of generator 3 with damage requiring repair in the factory

Under conditions, box 30 is delivered to box 10 along tracks 35 and 36. Open the cover 14, roll the trolley 30 into the opening 29 under the generator part 22 of the support frame 4, jack lifts 34 are brought under the intermediate support nodes 26 of the connecting beams 25, free generator 3 from communications with base 7, turbine unit 2 and communications, transmit weight

0 of the generator 3 by means of elevators 34 to the platform 30, which is moved along the paths 36 until the first carriage 33 is placed on the rotary cell 37, the section 12 is returned to its original position, the cell 37 is rotated 90 ° until its paths coincide with the longitudinal paths 35, the first carriage 33 is moved along the paths 35, and the second carriage 33 along the transverse paths until the latter reaches the reversed rotary cell 37, the second carriage 33 is deployed along the longitudinal paths 35 and the generator 3 is transported to the dispatch area for repair.

If the gas turbine unit 2 is damaged, its dismantling is carried out in a similar sequence after dismantling the generator 3 and its shelter in the auxiliary box 17, which is separately located on the territory of the station, for example, at the end of the longitudinal tracks 35 It is possible to use the auxiliary box 17 to repair the generator 3 with the extraction of its rotor, which is provided for by operational requirements m.

5, in this case, the auxiliary box 17 is delivered on the platform 30 to the corresponding main box 10, mounted on the distribution support parts 43, mated the contour connecting element 18 with the seal 19 to the contour butt element 16 on the bolts 20, demonstrate the cover 15 of the hatch 14 and receive the ability to disassemble the rotor and necessary repairs in the room.

. Using the auxiliary box 17 allows you to reduce the size of all the main boxes 10. Also reduces the size of the main boxes 10 location

0 of the air intake section in the 2nd Rus, while reducing the length of the air ducts 6. The presence of protrusions 27 on the base 7 significantly increases its stiffness, which leads to material savings, and allows

5 to transport the unit through the most economical land vehicle. At the same time, bottom 28 is used as the base under path 36, which also saves material. The implementation of the support frame 4 of two elements with a detachable connection between them makes it possible to reduce the size of the transport trolley 30 and use these elements as temporary supports during dismantling. The use of transport trolleys 30 instead of overhead cranes qualitatively reduces the cost of both building structures and the vehicles themselves. At the same time, the volume of the premises was reduced, the time of their installation and the workload were reduced. Operating and repair costs have also been reduced, since it is possible to quickly replace an emergency unit with a standby unit or one delivered to the station in connection with the airport. At the same time, the working conditions and the quality of repairs were improved. The economical and easy-to-operate drives of the transport trolleys 33 in the form of winches 38 with by-pass rollers 40 on additional bases 42.
