Abstract
The utility model provides a carrying channel arrangement structure of a hydraulic turbine disassembled below a hydropower station, which is applied to the hydropower station with the hydraulic turbine disassembling mode of disassembling below; two adjacent units are used as a pair, equipment transportation rails of each unit are arranged, the equipment transportation rails of the paired units are arranged in a convergent rail and communicated to a convergent point of the convergent rail, a public object lifting hole is arranged above the convergent point, and the object lifting hole is matched with the inlet and the outlet of a rotating wheel of the unit. The utility model discloses only arrange the angle through the change passageway of tearing down of unit in pairs, just can realize the public purpose that hangs the thing hole of two units to save the civil engineering investment in power station and increase other equipment and arrange the purpose in space.
Description
Technical Field
The utility model relates to a transport passageway arrangement structure of formula hydraulic turbine is torn open down in power station is applicable to and is equipped with even number unit, and adopts the power station of tearing open formula hydraulic turbine structure down.
Background
The hydraulic turbine of power station dismantles the mode and usually has to pull down, in pull down and pull down three kinds of modes, and wherein pull down formula structure can pull out runner, bottom ring, stator etc. of the hydraulic turbine and flow through fragile part and overhaul under the state of not dismantling the generator to avoid dismantling, the engineering volume of repacking to the generator that does not need to overhaul, practiced thrift repair time greatly.
In a hydropower station adopting a downward-dismounting type water turbine, a unit-type downward-dismounting carrying channel setting mode is generally adopted, namely, an independent downward-dismounting carrying channel is arranged on a water turbine layer (or a water inlet valve layer) of each unit and used for carrying dismounted rotating wheels, tail water cone pipes, bottom rings, guide vanes and other components. The above "unit" transfer lane arrangement mainly has the following two disadvantages: 1) because of arranging a plurality of transport passageway needs of tearing down, need the factory building length of extension power station, increase the construction investment of power station. 2) A plurality of lifting holes are required to be arranged on each unit generator layer to serve as lifting channels for disassembling equipment, so that the equipment arrangement space and the overhauling and maintaining space of the layer in a power plant can be influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: aiming at the problems, the carrying channel arrangement structure of the downward-dismounting type water turbine saves investment and does not influence the arrangement space of equipment in a plant. Therefore, the utility model adopts the following technical scheme:
a carrying channel arrangement structure of a hydraulic turbine disassembled downwards in a hydropower station is applied to the hydropower station with the hydraulic turbine disassembled downwards; the device is characterized in that two adjacent units are used as a pair, a device transportation rail is arranged for each unit, the device transportation rails of the paired units are arranged in a convergent rail and communicated to a convergent point of the convergent rail, a public object lifting hole is arranged above the convergent point, and the object lifting hole 4 is matched with the inlet and the outlet of a rotating wheel of the unit.
Further, the tracks 3 of the paired units are arranged symmetrically.
Furthermore, the arrangement structure is applied to a hydropower station which is provided with even number of units and has a water turbine disassembly mode of a downward disassembly type.
The utility model has the advantages that: the utility model discloses only arrange the angle through the change passageway of tearing down of unit in pairs, just can realize the public purpose that hangs the thing hole of two units to save the civil engineering investment in power station and increase other equipment and arrange the purpose in space.
Drawings
Fig. 1 is a plan view of an embodiment of the present invention.
Detailed Description
As shown in fig. 1. Two hydroelectric generating set units are arranged in a hydropower house, and the units are arranged in a downward-detachable structure. When the unit needs to be overhauled, the rotating wheel 1 of the unit is detached and placed on the carrying trolley 2, and the carrying trolley 2 runs on the equipment conveying track 3 of the carrying channel.
The utility model provides a lower transport passageway arrangement structure of tearing open formula hydraulic turbine is the equipment transportation track 3 of two mated units and assembles the track arrangement and lead to its convergent point 30, is equipped with the public thing hole 4 that hangs directly over convergent point 30, hang the discrepancy of the runner of the big small adaptation unit in thing hole 4. Therefore, the rotating wheels 1 of the two units can be conveyed to the position right below the common object hanging hole 4 through the structure and are hung out of the object hanging hole 4.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art can change, add or replace the above examples within the scope of the present invention.
Claims (3)
1. A carrying channel arrangement structure of a hydraulic turbine disassembled downwards in a hydropower station is applied to the hydropower station with the hydraulic turbine disassembled downwards; the device is characterized in that two adjacent units are used as a pair, a device transportation rail (3) of each unit is arranged for each unit, the device transportation rails (3) of the paired units are arranged in a convergent rail and communicated to a convergent point (30) of the convergent rail, a common object hanging hole (4) is formed above the convergent point, and the object hanging hole (4) is matched with the inlet and the outlet of a rotating wheel (1) of each unit.
