Description

Technical Field

[0002] In the installation of thermal power plants, the generator stator is an important core component of the steam turbine unit, and the completion node of its installation also belongs to a major construction period node of the whole project. With the continuous increase in the capacity of thermal power generating units, the volume and weight of the generator are also increasing continuously, and the single-piece weight of the generator stator is much greater than the lifting capacity of the overhead crane in the turbine building, which brings certain difficulties to the installation and positioning of the generator stator. After adopting the arc transition structure, the lifting rigging can be directly arranged on the beam, and the generator stator can be lifted and positioned without using a lifting hook.

[0003] However, the traditional conventional lifting of the generator stator uses an overhead crane for lifting. Usually, a lifting beam is used in cooperation with a large-tonnage lifting hook for lifting and positioning during the lifting process, which not only reduces the convenience, but also is prone to deviation in position during lifting. At the same time, vibration will be generated during operation, causing the lifting beam to be impacted and reducing its service life. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment, please refer to Figures 1 - 5 The present utility model provides a technical solution:

[0027] A large equipment hoisting crossbeam arc transition structure includes a hoisting crossbeam 1. The top of the hoisting crossbeam 1 is respectively provided with a top assembly 2 and a shock absorption assembly 3, and the top assembly 2 is located on the top of the shock absorption assembly 3.

[0028] In this embodiment, according to Figure 1 , Figure 2 and Figure 3As shown, the top component 2 includes a connecting plate 5 at the top of the hoisting crossbeam 1. At the top of the connecting plate 5, an arc plate 201 and a fixed baffle 202 are respectively arranged. The arc plate 201 is located on the side of the fixed baffle 202. The bottom of the arc plate 201 is fixedly connected to a support plate 203, and the bottom of the support plate 203 is fixedly connected to the connecting plate 5. On the side of the fixed baffle 202, a first bolt 204 is provided. The first bolt 204 penetrates through the fixed baffle 202 and extends into the arc plate 201. The first bolt 204 is threadedly connected to the fixed baffle 202. At the top of the fixed baffle 202, a second bolt 205 is provided. The second bolt 205 penetrates through the fixed baffle 202 and extends into the connecting plate 5. The second bolt 205 is threadedly connected to the fixed baffle 202. There are two fixed baffles 202, and the two fixed baffles 202 are respectively located on both sides of the arc plate 201. There are multiple support plates 203, and the multiple support plates 203 are all located between the arc plate 201 and the connecting plate 5.

[0029] Among them, the arc plate 201 and the hoisting crossbeam 1 are supported by the support plate 203. The support plate 203 can keep the arc plate 201 from deforming. When the sling or wire rope for hoisting directly acts on the arc plate 201 during hoisting, the fixed baffle 202 can limit the lateral offset of the position of the flexible sling or wire rope.

[0030] In this embodiment, according to Figure 1 、 Figure 4 and Figure 5 As shown, the shock-absorbing component 3 includes a guiding groove 301 opened at the top of the hoisting crossbeam 1. A guiding rod 302 is fixedly connected in the guiding groove 301. A shock-absorbing spring 303 is sleeved on the outer surface of the guiding rod 302. A moving block 304 is slidably connected to the outer surface of the guiding rod 302. The moving block 304 abuts against the shock-absorbing spring 303. The top of the moving block 304 is fixedly connected to a first fixing seat 305. The bottom of the connecting plate 5 is fixedly connected to a second fixing seat 306. An articulated rod 307 is hinged between the first fixing seat 305 and the second fixing seat 306. An installation groove 6 is opened at the top of the connecting plate 5. A weight sensor 7 is fixedly connected in the installation groove 6. An installation cover 4 is clamped at the opening of the installation groove 6. The installation cover 4 is located on the top of the weight sensor 7. The outer surface of the hoisting crossbeam 1 is coated with anti-corrosion paint. The connecting plate 5 has the same width as the hoisting crossbeam 1.

[0031] Among them, the first fixing seat 305 and the second fixing seat 306 are hinged by the articulated rod 307. When the arc plate 201 generates a downward pressure, the moving block 304 will squeeze the shock-absorbing spring 303, and then shock absorption can be achieved through the shock-absorbing spring 303.

[0032] Working process of the utility model: When a large equipment hoisting crossbeam with an arc transition structure designed by this solution is working, first check whether the device is in normal use. Fix the fixed baffle 202 on the connecting plate 5 through the second bolt 205, and connect it to the side of the arc plate 201 through the first bolt 204 to improve the stability of the arc plate 201 during operation. The arc plate 201 and the hoisting crossbeam 1 are supported by the support plate 203, and the support plate 203 can keep the arc plate 201 from deforming. When the sling or steel wire rope for hoisting directly acts on the arc plate 201 during hoisting, the fixed baffle 202 can limit the lateral displacement of the flexible sling or steel wire rope, ensuring that the flexible sling or steel wire rope always acts on the arc plate 201 without lateral displacement, improving convenience and stability. There is a damping effect between the connecting plate 5 and the hoisting crossbeam 1 during operation. Since the first fixed seat 305 and the second fixed seat 306 are hinged by the hinge rod 307, when the arc plate 201 generates downward pressure, the moving block 304 will squeeze the damping spring 303, and then damping can be achieved through the damping spring 303, thereby reducing the damage of vibration to the hoisting crossbeam 1. At the same time, an anti-corrosion paint is applied on the outer surface of the hoisting crossbeam 1 to improve the service life of the hoisting crossbeam 1. The staff can understand the load on the arc plate through the weight sensor 7, improving the practicability.
