Description

Technical Field

[0001] The utility model relates to the technical field of the support system of the air-cooling equipment of a power plant, in particular to a support structure of a brake for a W-shaped air-cooling transmission shaft. Background Art

[0002] In the northwest region of China, the water resource shortage is significant. However, there are many thermal power plants distributed in this area. To achieve the water-saving goal, these thermal power units widely adopt air-cooling technology, and the W-shaped air-cooling structure is a relatively common air-cooling form in recent years.

[0003] In a conventional W-shaped air-cooling system, the motor is generally arranged on the fan platform outside the wind筒, and is connected to the reducer inside the wind筒 through a long transmission shaft. When overhauling this system, the operators need to enter the inside of the wind筒. To ensure safety, it is required that the fan blades stop rotating at this time.

[0004] However, the actual situation is that most W-shaped air-coolings did not consider the blade braking device in the preliminary design, and a transmission shaft brake device needs to be added later to realize the braking of the fan blades. Since the flange of the transmission shaft to be braked is located between the motor and the wind筒, the space in this area is extremely narrow, and the fan platform is only a thin plate, and there is no steel structure support under it. If the brake equipment is directly placed on this thin plate platform, there will be problems such as ineffective fixation, which will lead to situations such as easy deformation of the equipment, insufficient stiffness, and poor stability.

Figure 2 DD section view, Figure 6 This utility model relates to a support structure for a W-type air-cooled drive shaft brake device. Figure 2 EE sectional view, such as Figure 1-6As shown in the figure, a support structure of a W-shaped air-cooled drive shaft holding brake device 8 of a preferred embodiment is shown, including a support beam 3, a fixed beam 7 and an equipment base plate 2. One end of the fixed beam 7 is perpendicularly welded to one end of the support beam 3. The other end of the fixed beam 7 and the other end of the support beam 3 are both perpendicularly welded to an octagonal beam 1, and together with the octagonal beam 1, they enclose a "square" structure. The equipment base plate 2 is arranged directly above the support beam 3. The holding brake device 8 is installed on the top of the equipment base plate 2. Two side vertical plates 4 and a middle vertical plate 5 are welded between the bottom of the equipment base plate 2 and the top of the support beam 3. The two side vertical plates 4 are respectively located on both sides of the equipment base plate 2, and the middle vertical plate 5 is welded between the two side vertical plates 4.

[0035] In this application, by enclosing a "square" structure with the support beam 3, the fixed beam 7 and the octagonal beam 1, and setting the two side vertical plates 4 and the middle vertical plate 5 between the equipment base plate 2 and the support beam 3, a stable and reliable support structure is provided for the holding brake device 8, effectively solving the problem that the original fan platform cannot fix the holding brake device 8 after adding the drive shaft holding brake device 8, enabling the holding brake device 8 to be stably installed and meeting the braking requirements of the fan blades.

[0036] More preferably, the octagonal beam 1 can be a part of the steel support structure on the periphery of an external device (such as a thermal power unit).

[0037] Furthermore, as a preferred embodiment, the support beam 3 includes an upper wing plate 31, a lower wing plate 32 and a web 33 connected between the upper wing plate 31 and the lower wing plate 32, and the upper wing plate 31, the lower wing plate 32 and the web 33 form an "I" - shaped structure; both side bottom plates and the middle vertical plate 5 are welded to the upper wing plate 31; two stiffening plates 6 are also welded between the upper wing plate 31 and the lower wing plate 32, and the two stiffening plates 6 are respectively located directly below the two side vertical plates 4.

[0038] In this application, the support beam 3 with an "I" - shaped structure has high strength and stiffness, and can better bear the weight of the holding brake device 8 and the acting forces during operation; the welding of both side bottom plates and the middle vertical plate 5 to the upper wing plate 31, and the setting of the two stiffening plates 6 further enhance the connection strength between the support beam 3 and the equipment base plate 2 and the stability of the overall structure, which is beneficial to controlling the height and planar position of the holding brake device 8 and the running amplitude during the braking process.

[0039] Furthermore, as a preferred embodiment, a number of first reinforcing plates 34 are provided between the upper wing plate 31 and the web 33, and between the lower wing plate 32 and the web 33. The setting of the first reinforcing plates 34 increases the connection strength between the upper wing plate 31, the lower wing plate 32 and the web 33, improves the overall stiffness and stability of the support beam 3, makes the support beam 3 not easily deformed when bearing the weight of the holding brake device 8 and the operating load, thus ensuring the normal operation of the holding brake device 8 and extending its service life.

[0040] Furthermore, as a preferred embodiment, a plurality of first reinforcing plates 34 are equally spaced along the length of the web 33. The equally spaced first reinforcing plates 34 can evenly distribute the load borne by the support beam 3, making the stress on each part of the support beam 3 more balanced, further enhancing the strength and stability of the support beam 3, and ensuring that the brake device 8 can operate stably under different working conditions.

[0041] Furthermore, as a preferred embodiment, several second reinforcing plates are provided between the equipment base plate 2 and each side upright plate 4, and between the upper wing plate 31 and each side upright plate 4. The provision of the second reinforcing plates enhances the connection strength between the equipment base plate 2, the upper wing plate 31, and the side upright plates 4, improves the integrity and stability of the entire support structure, and enables the vibration and force generated by the brake device 8 during operation to be better transmitted and dispersed, reducing local stress concentration, thereby ensuring the normal operation and service life of the brake device 8.

[0042] Furthermore, as a preferred embodiment, both the fixed beam 7 and the support beam 3 are I-beam structures. The fixed beam 7 and the support beam 3, both of which are I-beam structures, have high strength and rigidity, enabling them to better withstand the weight of the brake device 8 and various loads during operation. At the same time, the I-beam structure is easy to process and install, which helps to improve the overall performance and stability of the support structure and meet the support requirements of the brake device 8.

[0043] Furthermore, as a preferred embodiment, the octagonal beam 1 includes at least two structural beams 101, which are welded perpendicularly together. The other end of the fixed beam 7 and the other end of the supporting beam 3 are also welded perpendicularly to the two structural beams 101. The octagonal beam 1, composed of at least two vertically welded structural beams 101, forms a stable polygonal structural system when welded perpendicularly to the fixed beam 7 and the supporting beam 3. This enhances the stability and load-bearing capacity of the entire support structure, better adapting to the operating requirements of the brake device 8 under different working conditions and ensuring stable installation and operation of the equipment.

[0044] Furthermore, as a preferred embodiment, each structural beam 101 is an "I"-shaped steel structure.

[0045] Furthermore, as a preferred embodiment, the brake clamping device 8 and the equipment base plate 2 are connected by bolts. Connecting the brake clamping device 8 and the equipment base plate 2 by bolts facilitates the installation and disassembly of the brake clamping device 8, and makes equipment maintenance and repair easier; at the same time, the bolt connection provides reliable connection strength, ensuring that there is no relative displacement between the brake clamping device 8 and the equipment base plate 2 during operation, thus guaranteeing the normal operation of the equipment and its braking effect.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
