Moreover, during long-term braking operation, a large amount of heat can accumulate in the brake chassis, which can reduce the braking effect.

[0004] Therefore, a high-efficiency mechanical braking chassis for steam turbines is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A high-efficiency mechanical braking chassis for steam turbines includes a connecting chassis 1, an auxiliary component 2 fixedly connected to the top of the connecting chassis 1, and a heat dissipation component 3 fixedly connected to the top of the auxiliary component 2.

[0027] The heat dissipation assembly 3 includes a brake body 301. Through holes 302 are provided on both sides of the brake body 301. A conduit 303 is connected to the inner wall of the through hole 302. A square block 304 is connected to the other end of the conduit 303. A square groove 305 is provided on the top of the square block 304. The square groove 305 is connected to the other end of the conduit 303. An exhaust fan 306 is fixedly connected to the top of the square block 304.

[0028] In this embodiment: by setting a connecting chassis 1, the connecting chassis 1 can fix the auxiliary component 2; by setting a brake body 301, precise stopping can be achieved when the brake body 301 is braking; by setting a through hole 302, the through hole 302 can assist in guiding the installation position of the guide tube 303; by setting a guide tube 303, the guide tube 303 can guide the heat energy accumulated in the brake body 301 into the square groove 305 through the through hole 302; by setting a square block 304, the square block 304 can fix the guide tube 303 and fix the exhaust fan 306; by setting an exhaust fan 306, the exhaust fan 306 can remove the heat energy in the square groove 305, and extract the heat energy in the brake body 301 through the square groove 305, the guide tube 303 and the through hole 302.

[0029] Specifically, such as Figure 4 As shown, the auxiliary component 2 includes a guide rod 201, a damping spring 202 is sleeved on the surface of the guide rod 201, and a limit ring 203 is fixedly connected to the bottom of the guide rod 201. The bottom of the damping spring 202 contacts a positioning block 204.

[0030] Specifically, such as Figure 4 As shown, the top of the positioning block 204 is provided with a sliding hole 205, the inner wall of the sliding hole 205 is slidably connected to the surface of the guide rod 201, and the front side of the positioning block 204 is provided with a mating groove 206, which is connected to the sliding hole 205.

[0031] Specifically, such as Figure 1 , Figure 3 , Figure 4 As shown, a protective pad 4 is provided at the bottom of the inner wall of the mating groove 206. The protective pad 4 is made of rubber material.

[0032] In this embodiment: By setting the guide rod 201, the guide rod 201 can limit the damping spring 202, preventing the damping spring 202 from falling out of the desired position. When the guide rod 201 is pushed by the vibration force, it can slide within the sliding hole 205. The sliding hole 205 can limit the sliding position of the guide rod 201, preventing the sliding position from deviating. During sliding, the damping spring 202 moves closer to the positioning block 204 and is compressed. Through the rebound force of the damping spring 202, the guide rod 201 is reset. During the rebound process, the vibration force is relieved. The square groove 305 can provide the guide rod 201 with room to move. The protective pad 4 can protect the guide rod 201 and prevent damage due to accidental contact during the sliding process of the guide rod 201.

[0033] Specifically, such as Figure 2 As shown, a brake disc 5 is provided inside the brake body 301, and the brake disc 5 is circular.

[0034] Specifically, such as Figure 3 , Figure 5 As shown, a support 6 is fixedly connected to the bottom of the brake body 301. The bottom of the support 6 is fixedly connected to the top of the guide rod 201, and the bottom of the support 6 is in contact with the top of the damping spring 202.

[0035] In this embodiment: by setting a brake disc 5, the brake disc 5 can cooperate with the brake body 301 to achieve a precise braking effect. By setting a support 6, the support 6 can fix the brake body 301, and by contacting the damping spring 202, the support 6 can compress the damping spring 202 when it receives the impact of vibration.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, a turbine body 7 is fixedly connected to the rear side of the top of the chassis 1, and a shaft 8 is fixedly connected to the front side of the turbine. One end of the shaft 8 passes through the brake body 301 and extends to the front side of the brake body 301. The surface of the shaft 8 is fixedly connected to the inner wall of the brake disc 5.

[0037] Specifically, such as Figure 1 , Figure 2 As shown, a bearing 9 is fixedly connected to the surface of the other end of the shaft 8, and a fixing seat 10 is fixedly connected to the surface of the bearing 9. The fixing seat 10 is fixedly connected to the top of the connecting chassis 1.

[0038] In this embodiment: by setting the turbine body 7, the turbine body 7 can fix the shaft 8. The shaft 8 can fix the brake disc 5. The connection between the brake disc 5 and the shaft 8 means that there is no need to contact the shaft 8 during braking, so that the surface of the shaft 8 will not be worn due to braking. The bearing 9 can provide rotation space for the shaft 8. The fixing seat 10 can fix the bearing 9.

[0039] Working principle: When the turbine body 7 experiences vibration, the connection between the support 6 and the guide rod 201 causes the support 6 to move the guide rod 201 downwards. During this movement, the support 6, in conjunction with the positioning block 204, compresses the damping spring 202. The guide rod 201 is then limited by the sliding hole 205. Subsequently, the rebound force of the damping spring 202 resets the support 6, causing the guide rod 201 to reset as well. During the reset process, the guide rod 201 is limited by the limiting ring 203, allowing the guide rod 201 to... 01 will not detach from the sliding hole 205. When heat dissipation is required, the exhaust fan 306 can be powered on and started, so that the exhaust fan 306, under the fixation of the square block 304, can extract and discharge the heat energy accumulated in the brake body 301 through the square groove 305, the guide tube 303 and the through hole 302, thereby preventing the accumulation of heat energy in the brake body 301. When braking, the brake body 301 can be started, so that the brake body 301 clamps the brake disc 5, and uses the friction torque to reduce the speed of the shaft 8, and after deceleration, the turbine body 7 is stopped.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
