[0002] The intelligent noise reduction equipment for elevator traction systems is a device that reduces the noise generated by the traction system during elevator operation. Through mechanical structure optimization and material innovation, it reduces the operating noise of the traction system, thereby improving the comfort and environmental friendliness of elevator use.

[0003] The existing elevator traction system generates noise when controlling the raising and lowering of the car and counterweight plate. This noise not only affects the passenger experience but may also interfere with the surrounding environment of the machine room. Therefore, an intelligent noise reduction device for elevator traction systems is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent noise reduction device for elevator traction systems to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent noise reduction device for an elevator traction system, comprising a fixed base, a mounting platform fixedly connected to the top of the fixed base, a motor fixedly connected to the top of the mounting platform, a speed control and braking box fixedly connected to one side surface of the motor, a drive rod fixedly connected to the output end of the motor, a traction sheave fixedly connected to one end of the drive rod, a counterweight steel wire rope rotatably connected to the surface of the traction sheave, an elevator car steel wire rope rotatably connected to the surface of the traction sheave, and a volute-type sound insulation and sealing cover fixedly connected to one side surface of the speed control and braking box. The bottom of the volute-shaped soundproof sealing cover is provided with a counterweight plate limiting groove, and the bottom of the volute-shaped soundproof sealing cover is provided with an elevator car limiting groove. Interception nets are fixedly connected to both ends of the volute-shaped soundproof sealing cover, and streamlined sound-absorbing cotton is fixedly connected to both ends of the volute-shaped soundproof sealing cover. An installation groove is provided on the surface of the volute-shaped soundproof sealing cover, and a heat dissipation vent is provided inside the volute-shaped soundproof sealing cover. Several protective drainage rings are fixedly connected to the inner wall of the installation groove, and each of the protective drainage rings has an arc-shaped heat dissipation drainage groove inside. Several protective rods are fixedly connected to the inner wall of the installation groove.

[0006] By setting up the above structure, when the elevator is running, the volute-type soundproof sealing cover can wrap around the traction sheave to form a closed space, blocking the transmission of noise and protecting the internal components. The streamlined sound-absorbing cotton inside can absorb the noise of the traction sheave operation. Combined with the volute-type cavity, it can improve the noise reduction effect and improve the passenger ride comfort. The intercepting nets at both ends of the volute-type soundproof sealing cover can block the intrusion of debris and provide a stable environment for the noise absorption function of the streamlined sound-absorbing cotton.

[0012] By setting up counterweight plate limiting grooves and elevator car limiting grooves, the counterweight plate wire rope and elevator car wire rope can be guided to slide down respectively, constraining the running trajectory. The protective drainage ring in the installation groove protects the heat dissipation port through the annular structure. Its arc-shaped drainage groove, together with the heat dissipation port, can effectively dissipate heat.

With the coordinated cooperation of various structures, the heat dissipation and protection effect of the traction sheave in the elevator traction system can be achieved.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting a volute-shaped soundproof sealing cover, allows the elevator to enclose the traction sheave during operation, forming a closed space that blocks noise transmission and protects internal components. The streamlined sound-absorbing cotton inside absorbs the noise from the traction sheave's operation. Combined with the volute-shaped cavity, this enhances noise reduction and improves passenger comfort. The intercepting nets at both ends of the volute-shaped soundproof sealing cover prevent debris from entering, providing a stable environment for the streamlined sound-absorbing cotton to absorb noise.

The elevator has a streamlined sound-absorbing cotton 13 and a volute-shaped soundproof sealing cover 9. The surface of the volute-shaped soundproof sealing cover 9 has an installation groove 14, and the interior of the volute-shaped soundproof sealing cover 9 has a heat dissipation vent 15. Several protective drainage rings 16 are fixedly connected to the inner wall of the installation groove 14, and each of the protective drainage rings 16 has an arc-shaped heat dissipation drainage groove 17. Several protective rods 18 are fixedly connected to the inner wall of the installation groove 14. By setting up the volute-shaped soundproof sealing cover 9, when the elevator is running, the volute-shaped soundproof sealing cover 9 can wrap around the traction sheave 6 to form a closed space, blocking noise transmission and protecting internal components. The streamlined sound-absorbing cotton 13 inside can absorb the operating noise of the traction sheave 6. Combined with the volute-shaped cavity, it can improve the noise reduction effect and enhance passenger comfort. The intercepting nets 12 at both ends of the volute-shaped soundproof sealing cover 9 can prevent the intrusion of debris, providing a stable environment for the noise absorption function of the streamlined sound-absorbing cotton 13.

[0025] The drive rod 5 rotates inside the speed control and braking box 4.

[0026] The traction sheave 6 is located inside the volute-type soundproof sealing cover 9.

[0027] The counterweight plate wire rope 7 slides inside the counterweight plate limiting groove 10.

[0028] The elevator car wire rope 8 slides inside the elevator car limit groove 11.

[0029] Two intercepting nets 12 are located outside the streamlined sound-absorbing cotton 13. By setting the counterweight plate limiting groove 10 and the elevator car limiting groove 11, the two can guide the counterweight plate wire rope 7 and the elevator car wire rope 8 to slide down respectively, constraining the running trajectory. The protective drainage ring 16 in the mounting groove 14 protects the heat dissipation port 15 through the annular structure. Its arc-shaped drainage groove and heat dissipation port 15 can effectively dissipate heat. At the same time, the protective drainage ring 16 and the protective rod 18 can strengthen the structure of the mounting groove 14 and enhance the deformation resistance of the volute-type sound insulation sealing cover 9. With the coordinated cooperation of the various structures, the heat dissipation and protection effect of the traction wheel 6 in the elevator traction system can be achieved.

[0030] Working principle and usage process of this utility model:

[0031] The motor 3 is fixed by the fixed base 1 and the mounting platform 2. When the motor 3 starts, it drives the traction sheave 6 to rotate via the drive rod 5, which in turn pulls the counterweight steel wire rope 7 and the elevator car steel wire rope 8 to lift the elevator car and the counterweight. The speed control and braking box 4 synchronously controls the speed and braking of the drive rod 5. At the same time, the volute-shaped sound insulation sealing cover 9 wraps around the traction sheave 6. The streamlined sound-absorbing cotton 13 inside absorbs the operating noise of the traction sheave 6. The intercepting nets 12 at both ends prevent the intrusion of debris. The counterweight limit groove 10 and the elevator car limit groove 11 guide the counterweight steel wire rope 7 and the counterweight steel wire rope 7 to slide down respectively. The protective drainage ring 16 in the mounting groove 14 cooperates with the heat dissipation vent 15 through the arc-shaped heat dissipation drainage groove 17 to dissipate the heat generated by the operation of the traction sheave 6 in time. The protective rod 18 enhances the structural strength of the mounting groove 14, thereby reducing noise while ensuring the stable operation of the noise reduction equipment.
