Technical Field

[0001] The utility model relates to the field of traction machine brakes, in particular to an elevator traction machine brake. Background Art

[0002] The traction machine is a part of the elevator system, which is mainly used to provide the lifting power of the elevator. It provides traction by driving the steel rope of the elevator, so that the elevator can rise or fall. When the elevator needs to brake, a braking device is usually required to achieve this.

[0003] As the braking device of the traction machine, the traction machine brake is a mechanical part that slows down or stops the moving parts in the traction machine. It is generally divided into drum brakes, disc brakes and plate brakes. When the existing traction machine brake adopts disc brakes, the brake disc will rub back and forth with the brake surface, generating friction noise, which will cause the experience to deteriorate and cause customer complaints. Therefore, an elevator traction machine brake is proposed to address the above problems. Utility Model Content

[0010] Preferably, the noise reduction component includes a sound insulation cover, which is fixedly installed on the outer side of the side wall of the traction wheel close to the fixed plate, and the sound insulation cover is arranged on the outer side of the brake disc. An installation cavity is opened inside the sound insulation cover, and a through groove is opened on the inner wall of the sound insulation cover, and the upper and lower side walls of the installation cavity are respectively fixedly connected with sound insulation plates.

[0027] See also Figure 1-4 As shown, the elevator traction machine brake comprises a traction machine body 1, a rotating shaft 2 is fixedly mounted on the front end of the traction machine body 1, and a traction sheave 3 is fixedly mounted on the rotating shaft 2;

[0028] A fixed plate 4, wherein the fixed plate 4 is fixedly mounted on the front end of the traction machine body 1, and the rotating shaft 2 is rotatably connected to the fixed plate 4;

[0029] A brake assembly 6, mounted on the fixed plate 4, and the traction sheave 3 is braked by the brake assembly 6;

[0030] A noise reduction component 5 is arranged outside the brake component 6, and the noise generated during the braking process is reduced by the noise reduction component 5;

[0031] During operation, the traction machine body 1 drives the rotating shaft 2 and the traction wheel 3 to rotate, providing the lifting power of the elevator. When the elevator needs to stop or slow down, the braking component 6 applies force to the traction wheel 3 to prevent the traction wheel 3 from rotating, thereby braking the movement of the elevator, and absorbing the noise generated during the braking process through the noise reduction component 5 to prevent the noise from being too loud and affecting the surrounding environment.

[0032] The brake assembly 6 includes a brake disc 61, which is arranged between the traction wheel 3 and the fixed plate 4. A guide bolt 64 is movably installed in a through hole 66 opened on the fixed plate 4. One end of the guide bolt 64 is threadedly connected to the brake disc 61. A spring 65 is sleeved on the other end of the guide bolt 64. The two ends of the spring 65 are respectively fixedly connected to the fixed plate 4 and the end of the guide bolt 64. An electromagnetic block 62 is fixedly installed on the side wall of the fixed plate 4. A magnetic plate 63 is fixedly installed on the side wall of the brake disc 61. The magnetic plate 63 corresponds to the electromagnetic block 62. When working, When braking is required, the control system automatically energizes the electromagnetic block 62, and the electromagnetic block 62 generates a repulsive force that repels the magnetic plate 63, thereby pushing the magnetic plate 63 and the brake disc 61 to move toward the traction wheel 3. The guide bolt 64 and the through hole 66 cooperate to enable the brake disc 61 to move horizontally stably. The brake disc 61 contacts the traction wheel 3 to generate friction, thereby braking the traction wheel 3. During the braking process, the spring 65 is stretched. When braking is not required, the electromagnetic block 62 is de-energized, the repulsive force disappears, and the brake disc 61 is reset under the rebound action of the spring 65, thereby not blocking the rotation of the traction wheel 3.

[0033] The noise reduction component 5 includes a sound insulation cover 51, which is fixedly installed on the outer side of the side wall of the traction wheel 3 close to the fixed plate 4, and the sound insulation cover 51 is arranged on the outer side of the brake disc 61. An installation cavity 52 is opened inside the sound insulation cover 51, and a through groove 53 is opened on the inner wall of the sound insulation cover 51. The upper and lower side walls of the installation cavity 52 are respectively fixedly connected with sound insulation plates 54; during operation, noise is generated when the brake disc 61 contacts the side wall of the traction wheel 3, and the noise is blocked by the sound insulation cover 51 to preliminarily reduce the noise. In addition, the noise is introduced into the installation cavity 52 by opening a through groove 53 on the inner wall of the sound insulation cover 51, and the noise is further weakened by the sound insulation plate 54, which can effectively reduce the noise.

[0034] The sound insulation panels 54 on the upper and lower sides are provided in multiple groups and are arranged in an interlaced manner; when working, the noise is reduced multiple times by the multiple groups of sound insulation panels 54, thereby improving the noise reduction effect.

[0035] The sound insulation plates 54 on the upper and lower sides are inclined toward the through slot 53; during operation, when noise is introduced into the gap between the sound insulation plate 54 and the inner wall of the installation cavity 52, the noise will collide with the side wall multiple times, thereby effectively reducing the noise.

[0036] The side wall of the sound insulation cover 51 is provided with a mounting hole 8, in which a fixing bolt 7 is arranged, and a threaded hole 9 is provided on the side wall of the traction wheel 3 at a position corresponding to the mounting hole 8, and the fixing bolt 7 is threadedly connected in the threaded hole 9; during operation, the fixing bolt 7 and the threaded hole 9 cooperate to facilitate the installation and fixing of the sound insulation cover 51.

[0037] Embodiment 2

[0038] See also Figure 5 As shown, compared with Example 1, as another implementation of the utility model, the sound insulation board 54 is fixedly installed with sound-absorbing cotton 10 in the middle; when working, the sound-absorbing cotton 10 absorbs noise, which can further weaken the noise and improve the noise reduction effect.

[0039] Working principle: when braking is required during operation, the electromagnetic block 62 is automatically energized through the control system, and the electromagnetic block 62 generates a repulsive force that repels the magnetic plate 63, thereby pushing the magnetic plate 63 and the brake disc 61 to move toward the traction wheel 3. Through the cooperation of the guide bolt 64 and the through hole 66, the brake disc 61 can move stably horizontally, and the brake disc 61 contacts the traction wheel 3 to generate friction, thereby braking the traction wheel 3; during the braking process, the spring 65 is stretched. When braking is not required, the electromagnetic block 62 is powered off, the repulsive force disappears, and the brake disc 61 is driven to reset under the rebound action of the spring 65, thereby not blocking the rotation of the traction wheel 3. In addition, when the brake disc 61 contacts the side wall of the traction wheel 3, noise is generated. The noise is blocked by the soundproof cover 51 to initially reduce the noise. In addition, the noise is introduced into the installation cavity 52 by opening a through groove 53 on the inner wall of the soundproof cover 51, and the noise is further weakened by the soundproof board 54, which can effectively reduce the noise.
