Description

Technical Field

[0001] The utility model relates to the technical field of elevator rope wheels, in particular to an elevator rope wheel with a function of reducing vibration rate. Background Art

[0002] The elevator sheave, as an important component in the elevator system, plays a key role. The elevator sheave, also commonly known as the traction sheave or rope sheave, is a key component in the elevator system used to drive the elevator car up and down. It converts the rotational power of the motor into the vertical movement of the elevator car through the winding and friction of the wire rope.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1 to 4 As shown, the utility model provides an elevator rope reel with a function of reducing vibration rate, comprising a wheel frame 1;

[0029] A wheel body 2 movably connected to the inside of the wheel frame 1;

[0030] A traction rope 3 is wrapped around the surface of the wheel body 2, and the front and back sides of the wheel frame 1 are movably connected to the rocker arm 4 through a pin shaft. The side of the rocker arm 4 away from the wheel frame 1 is movably connected to the tensioning wheel 5 through a pin shaft. The side of the traction rope 3 away from the wheel body 2 is hung on the surface of the tensioning wheel 5. The tensioning wheel 5 is elastic. A transmission structure 6 is provided on the front side of the wheel frame 1, and the transmission structure 6 can drive the rocker arm 4 to swing.

[0031] refer to Figure 2 The transmission structure 6 includes a connecting frame 7 fixedly connected to the front of the wheel frame 1, and a screw 8 is movably connected to the interior of the connecting frame 7 through a bearing. The surface of the screw 8 is threadedly connected to a screw sleeve 9. The side of the rocker arm 4 close to the wheel frame 1 is fixedly connected to a sleeve 10, and the sleeve 10 extends to the interior of the connecting frame 7 away from the side of the rocker arm 4 and is located on the back of the screw sleeve 9. The back of the screw sleeve 9 is fixedly connected to a sliding rod 11 located inside the sleeve 10, and the sliding rod 11 is slidably connected to the sleeve 10. The right end of the screw 8 passes through the right side of the connecting frame 7 and is fixedly connected to the rotating wheel.

[0032] As a technical optimization solution of the present invention, precise control of the position of the rocker arm 4 is achieved through the cooperation of the screw 8, the screw sleeve 9, the sleeve 10, the slide rod 11 and the rotating wheel, which not only simplifies the operation process, but also improves the flexibility and accuracy of the adjustment. By rotating the rotating wheel, the screw 8 can be driven to rotate, and then the screw sleeve 9 can be driven to move, and finally the rocker arm 4 can be swung to adjust the position of the tensioning wheel 5 and the tension of the traction rope 3.

[0033] refer to Figure 4 The end of the rocker arm 4 away from the wheel frame 1 is movably connected to the bracket 12 through a pin shaft, and the end of the bracket 12 away from the rocker arm 4 is movably connected to the support roller 13 through a pin shaft. The end of the traction rope 3 away from the tensioning wheel 5 is hung on the surface of the support roller 13.

[0034] As a technical optimization solution of the present invention, by further connecting the bracket 12 and the support roller 13, an additional support point is provided for the traction rope 3, which helps to disperse the tension of the traction rope 3 and reduce the risk of wear and breakage caused by excessive force on a single point. At the same time, the rotation of the support roller 13 reduces the friction resistance between the traction rope 3 and the support roller 13, thereby reducing energy consumption and noise.

[0035] refer to Figure 3 The surface of the wheel frame 1 is fixedly connected to a cross bar 14 located at the top of the connecting frame 7, and a tooth plate 15 is fixedly connected to the side of the cross bar 14 away from the connecting frame 7. The end of the bracket 12 close to the rocker 4 is fixedly connected to a gear 16, and the gear 16 and the tooth plate 15 are engaged with each other.

[0036] As a technical optimization solution of the present invention, the meshing design of the gear 16 and the tooth plate 15 ensures the synchronization and stability of the rocker arm 4 and the support roller 13 during movement, thereby avoiding additional vibration and noise caused by the lack of synchronization between the rocker arm 4 and the support roller 13.

[0037] refer to Figure 4 The front of the tooth plate 15 is fixedly connected to an angle plate 17 , and the side of the angle plate 17 away from the tooth plate 15 is fixedly connected to the front of the cross bar 14 .

[0038] As a technical optimization solution of the present invention, the angle plate 17 is fixedly connected to the cross bar 14, thereby enhancing the connection strength between the tooth plate 15 and the wheel frame 1, helping to prevent the tooth plate 15 from being displaced or deformed during the force application process, thereby ensuring the accuracy and stability of the engagement between the gear 16 and the tooth plate 15.

[0039] refer to Figure 4 The back of the support roller 13 is fixedly connected to a limiting ring 18 , and the traction rope 3 is located between the limiting ring 18 and the bracket 12 .

[0040] As a technical optimization solution of the present invention, by providing a limiting ring 18, the position of the traction rope 3 on the support roller 13 is limited, thereby preventing the traction rope 3 from deflecting or falling off during operation.

[0041] The working principle and use process of the utility model are as follows: the rope-winding wheel is in a stationary state, the wheel body 2 is located inside the wheel frame 1, the traction rope 3 is wound around the surface of the wheel body 2, the rocker arm 4 is movably connected to the front and back sides of the wheel frame 1 through a pin, and the tensioning wheel 5 is movably connected to the side of the rocker arm 4 away from the wheel frame 1 through a pin. The tensioning wheel 5 is elastic and can be extended and retracted as needed to adjust the tension of the traction rope 3. The movement of the screw sleeve 9 is connected through the sliding rod 11 and the sleeve plate 10 to drive the rocker arm 4 to swing on the wheel frame 1, and the swing of the rocker arm 4 will further drive the tensioning wheel 5 to move. Since the tensioning wheel 5 is elastic, it will expand and contract according to the position change of the rocker arm 4, thereby adjusting the winding tightness and angle of the traction rope 3 on the tensioning wheel 5. This adjustment helps to reduce the vibration and noise of the traction rope 3 during operation. In order to more accurately control the position of the rocker arm 4 and the support roller 13, when the rocker arm 4 drives the bracket 12 to move, the gear 16 on the bracket 12 will engage with the tooth plate 15 fixed on the cross bar 14. This meshing relationship ensures the synchronous movement of the rocker arm 4 and the support roller 13, thereby achieving more stable and precise control of the traction rope 3.

[0042] To sum up: the elevator rope pulley with the function of reducing the vibration rate realizes the effective tensioning and adjustment of the traction rope 3 through the combined design of the wheel body 2, the wheel frame 1, the rocker arm 4 and the tensioning pulley 5. The elastic design of the tensioning pulley 5 can absorb part of the vibration, thereby reducing the vibration rate during the operation of the elevator and improving the comfort and safety of riding.
