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 delivery of parts and on-site assembly during delivery or transportation, and parts of the high-power steam turbine need to be packaged during transportation, so that the risk of collision between a steam turbine rotor and static parts such as a steam seal, an oil retainer, a baffle 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 delivering the whole turbine, and is generally long-distance transportation of thousands of kilometers, road conditions are complex in transportation, various states such as frequent start and stop, acceleration, sudden braking, turning, jolt and the like can occur in a transportation vehicle, and because the inertia of the vehicle and the steam turbine equipment is large, the running state of the vehicle changes once every time, and the rotor inside the steam turbine and each static part sleeve have the risk of collision once, so that the 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 that before delivery and transportation, a bearing cover is opened, a thrust tile is taken out, an iron block is screwed in at the position of the thrust tile and clamped between a thrust disc of a turbine rotor and a thrust bearing support, so that the turbine is in a clamping state, and a clearance for front-back movement is avoided, thereby ensuring the transportation safety of the turbine. However, the method increases the complexity of the installation process to a certain extent, the bearing box cover increases the two disassembly and assembly processes along with the installation-taking out-installation of the thrust bearing, and the risk of abrasion of the turbine thrust disc is increased.
Disclosure of Invention
The invention aims to provide a novel auxiliary transportation device for a steam turbine, which is used for guaranteeing the safety of the steam turbine equipment in the transportation and loading and unloading processes.
The purpose of the invention is realized in the following way:
The invention relates to a novel auxiliary transportation device for a steam turbine, which is characterized in that: the novel rotor disc comprises a blocking plate, a limiting bolt and a cushion block, wherein the blocking plate is fixed on the end face of a rear shaft water tank through the blocking plate bolt, the cushion block is located between the end face of a rotor rear disc and the blocking plate, a protruding portion is arranged on one side of the cushion block, one side of the limiting bolt is provided with a hole, and the limiting bolt penetrates through the blocking plate and the protruding portion is inserted into the hole of the limiting bolt.
The invention may further include:
1. And a locking nut is arranged on the limit bolt part outside the blocking plate.
2. An asbestos rubber plate is arranged between the cushion block and the end face of the rotor rear wheel disc.
The invention has the advantages that: the auxiliary transportation device ensures that all parts of the steam turbine are not knocked in the transportation process, further ensures the overall safety and reliability of the steam turbine equipment, and can protect the cleanliness of the inside of the steam turbine to a certain extent and prevent pollutants from entering from the end part.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The invention is described in more detail below, by way of example, with reference to the accompanying drawings:
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 face of a rear wheel disc of a 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 assembly process, so that the rotor is prevented from being scratched. The blocking plate 5 is similar to a blind flange, a threaded through hole is formed in the center of the blind flange, the locking nut 3 is screwed into the limit bolt 2, and then screwed into the blocking plate 5 together until the cushion block 1 can contact the end face of the flange behind the rotor, and the protruding portion of the cushion block 1 is inserted into a hole corresponding to the limit bolt 2 at the other side of the blocking plate 5. After the blocking plate 5 is fixed with the end face of the rear bearing box by using the blocking plate bolt 4, the rotor is tightly propped by using the limit bolt 2, and finally, the cushion block 1 is locked by using the locking nut 3. This completes the axial limit of the rotor. After the use is finished, the blocking plate bolts 4 are directly removed one by one, and the whole dismantling of the device can be finished.
The realization process of the auxiliary transportation device comprises the following steps:
1. Starting from the end of the turbine rear bearing housing, a rational design is considered at this location. The end flange is matched with corresponding limit bolts, nuts, cushion blocks and the like to form the shaft end rotor plugging tool.
2. The installation flow of the tool is clear, and the convenience of assembly and disassembly is ensured.
The invention adopts the structural technologies of adding end flanges, limit bolts and the like, ensures the overall safety and reliability of the unit, and has simple structure and convenient operation.
