Description
Technical Field
The invention relates to a steam turbine, in particular to an auxiliary transportation device of the steam turbine.
Background
The high-power steam turbine generally adopts a mode of bulk delivery and field assembly during delivery or transportation, and parts of the high-power steam turbine need to be packaged in the transportation process, so that the risk of collision between a steam turbine rotor and static parts such as a steam seal, an oil retainer, a partition plate, a cylinder and the like does not exist. The small-sized steam turbine or the marine steam turbine generally adopts a transportation mode of complete machine delivery, and generally adopts long-distance transportation over thousands of kilometers, road conditions are complex in transportation, transportation vehicles can have various states such as frequent start-stop, acceleration, emergency braking, turning, bumping and the like, and because the inertia of the vehicles and the steam turbine equipment is large, when the driving state of the vehicles is changed once, a rotor inside the steam turbine and each static part sleeve have a risk of colliding with each other once, so that great safety risk is brought to the steam turbine in the transportation and loading and unloading processes.
The traditional method for solving the problem is to open the bearing cover before delivery and transportation, take out the thrust pad, screw in an iron block at the position of the thrust pad to be clamped between the thrust disc of the turbine rotor and the thrust bearing support, so that the turbine is in a 'blocked' state without a clearance of front and back movement, thereby ensuring the safety of the transportation of the turbine. However, the method increases the complexity of the installation process to a certain extent, and the bearing box cover increases two times of dismounting processes along with the 'installation-taking-out-installation' of the thrust pad, and also increases the risk of abrasion of the thrust disc of the steam turbine.
Disclosure of Invention
The invention aims to provide a novel auxiliary steam turbine transportation device for guaranteeing the safety of steam turbine equipment in the transportation and loading and unloading processes.
The purpose of the invention is realized by the following steps:
the invention relates to a novel auxiliary transportation device for a steam turbine, which is characterized in that: including closure plate, spacing bolt, cushion, the closure plate passes through the closure plate bolt fastening on rear axle water tank terminal surface, and the cushion is located between rotor rear wheel dish terminal surface and the closure plate, and the cushion sets up the bulge towards one side of closure plate, and a side of spacing bolt is opened porosely, and spacing bolt passes closure plate and bulge and inserts in the hole to spacing bolt.
The present invention may further comprise:
1. and a locking nut is arranged on the limiting bolt part outside the blocking plate.
2. An asbestos rubber plate is arranged between the cushion block and the end face of the rear wheel disc of the rotor.
The invention has the advantages that: the auxiliary transportation device provided by the invention ensures that all parts of the steam turbine are not collided in the transportation process, so that the overall safety and reliability of the steam turbine equipment are ensured, and in addition, the auxiliary transportation device can also protect the cleanliness inside the steam turbine to a certain extent and prevent pollutants from entering from the end part.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will now be described in more detail by way of example with reference to the accompanying drawings in which:
with reference to fig. 1, the invention comprises a cushion block 1, a rotor limit bolt 2, a lock nut 3, a blocking plate 5 and a blocking plate bolt 4, wherein the cushion block 1 is positioned between the limit bolt 2 and the end surface of the rear wheel disc of the rotor, and the contact surface of the cushion block 1 and the rotor is applied to an asbestos rubber plate pad with the thickness of about 3mm in the assembling process, so that the rotor is prevented from being scratched. The blocking plate 5 is similar to a blind plate flange, a threaded through hole is formed in the center of the blocking plate, the locking nut 3 is screwed into the limiting bolt 2, then the locking nut is screwed into the blocking plate 5 together until the cushion block 1 can contact with the end face of the flange behind the rotor, and the protruding portion of the cushion block 1 is inserted into the opening corresponding to the limiting bolt 2 on the other side of the blocking plate 5. After the blocking plate 5 is fixed well with the end face of the rear bearing box through the blocking plate bolt 4, the rotor is tightly jacked through the limiting bolt 2, and finally the cushion block 1 is locked through the locking nut 3. This completes the axial position limitation of the rotor. After the device is used, the whole device can be dismantled by directly dismantling the blocking plate bolts 4 one by one.
This auxiliary transportation device implementation process:
1. starting from the end of the rear bearing box of the steam turbine, reasonable design is considered at the position. The end flange is matched with a corresponding limiting bolt, a corresponding nut, a corresponding cushion block and the like to form a shaft end rotor plugging tool.
2. The installation process of the tool is determined, and the convenience of assembly and disassembly is ensured.
The invention adopts the structure technology of adding end flanges, limiting bolts and the like, ensures the integral safety and reliability of the unit, and has simple structure and convenient operation.
