Description

Technical Field

[0001] This utility model relates to the field of steam turbine technology, specifically a transport base for a steam turbine. Background Technology

[0002] A steam turbine, also known as a steam engine, is a rotary steam power unit. High-temperature, high-pressure steam passes through a fixed nozzle, becomes an accelerated airflow, and is then injected onto blades, causing a rotor equipped with rows of blades to rotate and perform work. Steam turbines are the main equipment in modern thermal power plants and are also used in the metallurgical industry, chemical industry, and ship propulsion systems.

The fastening bolt 4 matches the fixing hole. There are two fixing holes on one side, and there is a washer between the fastening bolt 4 that matches the two fixing holes. The washer can relieve vibration.

[0023] Fastening ropes 11 are respectively fitted at both ends of the turbine body 6. During the installation, the fastening ropes 11 can be wound several times as needed. The fastening ropes 11 are steel wire ropes. The two ends of the turbine body 6 are fixed by the fastening ropes 11, which further enhances the stability of the turbine body 6 during transportation.

A clamping block 10 is fixed to the telescopic end of the electric push rod 9, and the clamping block 10 abuts against the fastening rope 11. After the fastening rope 11 is wound up, both ends of the fastening rope 11 are passed through mounting blocks 7, and the electric push rod 9 pushes the clamping block 10 to move, causing the clamping block 10 to clamp the fastening rope 11 tightly, preventing it from loosening.

[0025] The top surface of support block 2 and the bottom surface of top block 3 are respectively provided with arc-shaped grooves, and the top and bottom surfaces of turbine body 6 are respectively in contact with the arc-shaped grooves. Both arc-shaped grooves are smaller than semicircles, and the arc-shaped grooves can play a certain limiting role for turbine body 6.

Finally, it is fixed by fastening bolts 4.

[0027] Rubber rings are fitted at both ends of the surface of the turbine body 6, and rubber pads are attached to the surface of the arc-shaped groove. The fastening rope 11 is fitted onto the surface of the rubber rings. The rubber rings and rubber pads are used to increase friction.

A retaining block 10 is slidably disposed within the grooves 12, and multiple retaining grooves 14 are formed at the end of the retaining block 10 closest to the fastening rope 11. Rubber rings are attached to the surface of the retaining grooves 14, which abut against the fastening rope 11. After the fastening rope 11 passes through the mounting hole, the retaining block 10 can be moved by the electric push rod 9, and the retaining block 10 abuts against the fastening rope 11 through the retaining grooves 14, at which point the fastening rope 11 is secured within the mounting hole and the retaining grooves 14.
