Description

Technical Field

[0001] The utility model relates to the technical field of generators, and more specifically, to a braking device for a thermal generator. Background Art

[0002] A thermal power generator is an important piece of electricity production equipment. It uses the combustion of fuel to generate heat energy, and then through a series of energy conversion processes, it ultimately converts the heat energy into electrical energy.

[0003] Traditional thermal power generator braking systems have the following drawbacks: Due to the asynchronous braking action of the brake pads, the force applied to both sides of the brake disc is unevenly distributed. This uneven force distribution accelerates uneven wear of the brake pads, increasing replacement frequency and maintenance costs. Furthermore, it can induce vibration or shaking during braking, reducing the stability and safety of the generator set and even posing a risk of damage to surrounding equipment and structures. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a braking device for a thermal generator, which has the advantage of being easy to use.

[0026] When the brake disc 2 needs to be braked, the servo motor 10 is started, so that the servo motor 10 drives the screw 9 to rotate, the screw 9 drives the connecting block 8 to move inward, and the connecting block 8 drives the rectangular plate 6 to move inward, so that the tooth block 12 drives the gear 13 to rotate, the gear 13 drives the circular shaft 14 to rotate, and the circular shaft 14 drives the circular block 15 to rotate, so that the connecting rod 16 swings inward, thereby driving the brake pad 27 to contact the brake disc 2, and the brake disc 2 is braked by the friction between the brake pad 27 and the brake disc 2.

[0027] By starting the servo motor 10, the rectangular plate 6 moves inward to drive the gear 13 to rotate, and the connecting rod 16 moves inward, thereby driving the brake pad 27 to contact the brake disc 2, so that the brake disc 2 is braked by the friction between the brake pad 27 and the brake disc 2. Compared with the braking device of the traditional thermal power generator, the braking device of this thermal power generator clamps and brakes the brake disc 2 by the synchronous inward movement of the brake pad 27, thereby achieving the effect of synchronous braking, making the wear of the brake pad 27 consistent, and improving the service life of the brake pad 27.

[0028] Among them, a slot 23 is opened at the front end of the mounting plate 22, and card slots 24 are opened on both sides of the inside of the slot 23. An insertion shaft 26 is movably installed inside the slot 23, and blocks 28 located inside the card slot 24 are fixedly installed on both sides of the bottom of the insertion shaft 26.

The return spring 25 is located on the inner side of the insertion shaft 26.

[0029] When the brake pad 27 needs to be replaced, just press the brake pad 27 inward to make the plug shaft 26 move inward to drive the block 28 out of the inside of the slot 24, then rotate the brake pad 27 to make the plug shaft 26 drive the block 28 to rotate, and rotate the block 28 to the bottom of the slot 23. At this time, the return spring 25 releases its elastic potential energy to push the block 28 out of the inside of the slot 23, thereby removing the brake pad 27.

[0030] By pressing the brake pad 27 inward, the plug shaft 26 moves inward to drive the block 28 out of the inside of the slot 24, and the block 28 is rotated to the bottom of the slot 23. At this time, the return spring 25 releases its elastic potential energy to push the block 28 out of the inside of the slot 23, thereby removing the brake pad 27. Compared with the braking device of the traditional thermal power generator, the braking device of this thermal power generator disengages the block 28 from the slot 23 by pressing and rotating the brake pad 27, thereby completing the replacement of the brake pad 27, which is convenient for use.

[0031] A limiting groove 7 is provided above the boss 5 , and a connecting block 8 is fixedly installed below the rectangular plate 6 , and the connecting block 8 is movably connected to the inside of the limiting groove 7 .

[0034] The servo motor 10 is started, so that the servo motor 10 drives the screw 9 to rotate, the screw 9 drives the connecting block 8 to move inward, and the connecting block 8 drives the rectangular plate 6 to move inward.

[0035] Among them, gear blocks 12 are evenly fixedly installed on both sides of the rectangular plate 6, and the gear blocks 12 are engaged with the gears 13. A long plate 11 is fixedly installed on the front end of the rectangular plate 6.

[0036] The connecting block 8 drives the rectangular plate 6 to move inward, so that the tooth block 12 drives the gear 13 to rotate, the gear 13 drives the circular shaft 14 to rotate, and the circular shaft 14 drives the circular block 15 to rotate.

[0037] A fixing block 17 is fixedly installed above the circular shaft 14 , and the fixing block 17 is located above the circular block 15 .

[0038] By installing the fixing block 17 above the circular shaft 14 , the fixing block 17 limits the circular block 15 to prevent the circular block 15 from being separated from the circular shaft 14 .

[0041] The working principle and use process of this utility model:

[0042] When the brake disc 2 needs to be braked, the servo motor 10 is started, so that the servo motor 10 drives the screw 9 to rotate, the screw 9 drives the connecting block 8 to move inward, and the connecting block 8 drives the rectangular plate 6 to move inward, so that the tooth block 12 drives the gear 13 to rotate, the gear 13 drives the circular shaft 14 to rotate, and the circular shaft 14 drives the circular block 15 to rotate, so that the connecting rod 16 moves inward, thereby driving the brake pad 27 to contact the brake disc 2, and thus the brake disc 2 is braked by the friction between the brake pad 27 and the brake disc 2.

[0043] When the brake pad 27 needs to be replaced, just press the brake pad 27 inward to make the plug shaft 26 move inward to drive the block 28 out of the inside of the slot 24, then rotate the brake pad 27 to make the plug shaft 26 drive the block 28 to rotate, and rotate the block 28 to the bottom of the slot 23. At this time, the return spring 25 releases its elastic potential energy to push the block 28 out of the inside of the slot 23, thereby removing the brake pad 27.
