Technical Field

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

[0003] At present, with the continuous development of science and technology, the power of steam turbines is getting bigger and bigger, but it also makes the transportation of steam turbines difficult. Steam turbines are often placed on a transport base and pulled and moved by large transport machinery.

[0004] In the process of moving the steam turbine on a transport base, when encountering a bumpy road section, the steam turbine on the transport base is prone to shaking, and may even cause the steam turbine to topple over and injure workers. Therefore, a transport base for a steam turbine that can limit the position of the steam turbine is proposed. Utility Model Content

[0008] Preferably, a slide groove is provided at the front and rear of the top of the base and at one side of the installation frame, and a blocking plate is slidably connected inside the two slide grooves via a slider.

[0009] Preferably, the front and rear portions of one side of the blocking plate are fixedly connected with ropes, and one end of the rope is fixedly connected to the outer surface of the connecting plate.

[0011] Preferably, a second guide frame adapted to the rope is fixedly connected to the top of the fixed plate.

[0012] Beneficial Effects

[0013] The utility model provides a transport base for a steam turbine. Compared with the existing technology, it has the following advantages:

[0014] Beneficial effects:

[0015] The utility model controls the extension of two electric telescopic rods at the same time, so that the electric telescopic rod drives the connecting plate to move, and the connecting plate drives the arc-shaped limit plate to move through the telescopic tube and the telescopic rod, so that the two arc-shaped limit plates are close to the steam turbine, and the front and rear sides of the steam turbine are clamped, thereby limiting the position of the steam turbine well, and effectively preventing the steam turbine from shaking during transportation; and the rubber pad under the steam turbine can well reduce the impact force of the steam turbine shaking, thereby better protecting the steam turbine and ensuring the stability of steam turbine transportation.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1-3The utility model provides a technical solution: a transport base for a steam turbine, comprising a base 1 and a steam turbine 2 located above the base 1, a mounting frame 3 is fixedly connected to the top of the base 1, a rubber pad 4 is slidably connected to the inside of the mounting frame 3, a fixing plate 5 is fixedly connected to the front and rear of the top of the mounting frame 3, an electric telescopic rod 6 is fixedly connected to the top of the opposite side of the two fixing plates 5, the electric telescopic rod 6 is electrically connected to an external power supply and is controlled by a control switch, and a limiting mechanism 7 adapted to the steam turbine 2 is provided at the telescopic end of the electric telescopic rod 6.

[0022] It should be noted that, by installing the rubber pad 4 in the frame 3, the impact force on the shaking of the turbine 2 can be effectively reduced, and by sliding the sealing plate 9 out of the slide groove 8, the rubber pad 4 can be conveniently taken out and replaced, and then the new rubber pad 4 is put into the installation frame 3, and then the sealing plate 9 is slid into the slide groove 8 for sealing.

[0023] Furthermore, in order to seal the rubber pad 4 in the installation frame 3 and facilitate the replacement of the rubber pad 4, a slide groove 8 is opened at the front and rear of the top of the base 1 and on one side of the installation frame 3, and the inside of the two slide grooves 8 is slidably connected with a sealing plate 9 through a slider.

[0024] Furthermore, in order to pull the blocking plate 9 to block the right side of the installation frame 3, the front and rear parts of one side of the blocking plate 9 are fixedly connected with a rope 10, one end of the rope 10 is fixedly connected to the outer surface of the connecting plate 71, the front and rear parts of the top of the installation frame 3 and one side of the fixed plate 5 are fixedly connected with a first guide frame 11 adapted to the rope 10, and the top of the fixed plate 5 is fixedly connected with a second guide frame 12 adapted to the rope 10.

[0025] Furthermore, in order to limit the steam turbine 2, the limiting mechanism 7 includes a connecting plate 71, which is fixedly connected to the telescopic end of the electric telescopic rod 6, and a telescopic cylinder 72 is fixedly connected to the side of the connecting plate 71 close to the steam turbine 2, and a telescopic rod 73 is slidably connected inside the telescopic cylinder 72, and an arc-shaped limiting plate 74 is fixedly connected to the end of the telescopic rod 73 close to the steam turbine 2, and a spring 75 is sleeved between the outer surface of the telescopic cylinder 72 and the outer surface of the telescopic rod 73.

[0026] When in use, put the rubber pad 4 into the installation frame 3, and then place the steam turbine 2 on the rubber pad 4, and control the two electric telescopic rods 6 to extend at the same time, so that the electric telescopic rod 6 drives the connecting plate 71 to move, so that the connecting plate 71 drives the arc-shaped limiting plate 74 to move through the telescopic cylinder 72 and the telescopic rod 73, so that the two arc-shaped limiting plates 74 move toward the middle, and the two arc-shaped limiting plates 74 will limit the steam turbine 2. Through the action of the spring 75, the telescopic cylinder 72 and the telescopic rod 73 further push the arc-shaped limiting plate 74, so that the limiting of the steam turbine 2 is more stable. When the connecting plate 71 moves, the connecting plate 71 will pull the rope 10, so that the rope 10 pulls the blocking plate 9 to move to the left, so that the blocking plate 9 blocks the right side of the installation frame 3;

[0027] When the steam turbine 2 needs to be removed, the two electric telescopic rods 6 are controlled to contract at the same time, so that the two arc-shaped limit plates 74 move forward and backward, and the two arc-shaped limit plates 74 no longer limit the steam turbine 2. At the same time, the two connecting plates 71 move forward and backward, so that the connecting plates 71 no longer pull the rope 10, and the rope 10 no longer tightens the blocking plate 9. Then the staff pulls the blocking plate 9 to the right to slide the blocking plate 9 out of the two slide grooves 8, so that the blocking plate 9 no longer blocks the rubber pad 4. After the steam turbine 2 is removed, the rubber pad 4 is taken out and replaced by pulling it to the right.
