Description

Technical Field

[0001] The utility model relates to the field of elevator equipment, in particular to an anti-slip mechanism for winding elevator steel ropes. Background Art

[0002] With the continuous development of urban construction, a traction machine is the power device of an elevator. The traction wheel of the existing traction machine is placed inside the machine base. When assembling and overhauling the steel rope, it is necessary to open the machine base for operation. The winding of the elevator steel rope completes the lifting and lowering of the elevator car.

[0003] According to the retrieved anti-slip mechanism for a steel rope with the publication number of CN2730616Y, it includes a fixed shaft, a swing frame, a rotating shaft, a rolling wheel, a V-shaped rolling wheel frame and a steel rope. Two three-section arm type swing frames, one end of which is sleeved on the fixed shaft, and a grooved roller is provided at the other end of the two swing frames. A V-shaped rolling wheel frame is installed on the swing frame, and the V-shaped rolling wheel frame can rotate relative to the swing frame. A rotating shaft with a wedge-shaped groove is provided between the two V-shaped rolling wheel frames. The steel rope is wound in the wedge-shaped groove of the rotating shaft. A rolling wheel is provided on the V-shaped rolling wheel frame, and the rolling wheel presses against the outer edge of the steel rope. This mechanism can work both when the rotating shaft rotates clockwise and counterclockwise. There is no slipping phenomenon between the steel rope and the rotating shaft, effectively reducing the wear of the steel rope. It can be used in places where no slipping is required between the steel rope and the rotating shaft, such as: the drum of a winch, a high-rise escape device, etc.

[0004] However, when implementing the above technical solutions, the following problems exist: In the above technical solutions, there are many pulleys around which the steel rope is wound, which is not conducive to the winding of the steel rope. The wear rate of the rolling frame and the rolling wheel is too high during use, and the service life of the overall structure is relatively low. It cannot prevent the end of the steel rope from stretching and shaking during winding, and does not provide good protection for the internal shaft. The internal structure is relatively compact and complex, which is not convenient for elevator workers to monitor, install, disassemble and repair. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: an anti-slip mechanism for winding elevator steel ropes, including a main body frame 1 and a winding mechanism 5. Fixed shaft seats 2 are arranged on both sides of the top of the main body frame 1. An inner side of one end of the fixed shaft seat 2 is provided with a motor mounting seat 3. A motor protection housing 4 is arranged on the top of the motor mounting seat 3. The winding mechanism 5 is arranged inside the motor protection housing 4. A traction motor 501 is arranged on the top of the motor mounting seat 3. A driving rope wheel 502 is arranged on one side of the traction motor 501. An elevator steel cable 503 is wound around the outer surface of the driving rope wheel 502. A protection disc 504 is arranged at an outer end of the driving rope wheel 502. A steel cable isolation rod 505 is arranged outside the driving rope wheel 502. A central bottom plate 506 is arranged on one side of the bottom of the motor mounting seat 3. Buffer springs 507 are arranged on both sides of the central bottom plate 506. A steel cable chute 508 is arranged outside the buffer springs 507.

[0022] Furthermore, the winding mechanism 5 includes a traction motor 501, a driving rope wheel 502, an elevator steel cable 503, a protection disc 504, a steel cable isolation rod 505, a central bottom plate 506, buffer springs 507 and a steel cable chute 508. The bottom of the main body frame 1 is a machine room floor 6. A cable groove 7 is formed in the center of the central bottom plate 506. The cable groove 7 enables the elevator steel cable 503 during the winding process to always rise and fall within a specified area, improving the personal safety of elevator maintenance personnel in the machine room.

[0023] Furthermore, the main body frame 1 and the fixed shaft seat 2 are fixedly connected. There are two groups of fixed shaft seats 2. The fixed shaft seat 2 and the motor mounting seat 3 are fixedly connected. The motor mounting seat 3 and the motor protection housing 4 are connected by a card slot. The main body frame 1 and the fixed shaft seat 2 lift the height of the winding mechanism 5 away from the ground, facilitating better monitoring, maintenance, installation and disassembly of the winding mechanism 5 by elevator maintenance personnel. The motor mounting seat 3 is used to mount the traction motor 501, and the motor protection housing 4 is used to protect the traction motor 501. While ensuring good ventilation and cooling of the traction motor 501, foreign objects are prevented from falling in to prevent damage to the traction motor 501.

[0024] Furthermore, the traction motor 501 is rotatably connected to the drive sheave 502. The drive sheave 502 is provided with several groups of transmission grooves. The traction motor 501 is in transmission connection with the elevator steel cable 503 through the drive sheave 502. The transmission grooves of the drive sheave 502 correspond to the elevator steel cables 503 one by one. The width of the transmission grooves of the drive sheave 502 matches the diameter of the elevator steel cable 503. The drive sheave 502 with a larger diameter improves the structural strength of the winding mechanism 5. At the same time, the multiple groups of transmission grooves provided on the drive sheave 502 are used to wind multiple groups of elevator steel cables 503, increasing the friction with the elevator steel cables 503, preventing the elevator steel cables 503 from slipping and the drive sheave 502 from idling when the drive sheave 502 rotates, reducing the probability of elevator lifting failures, and improving the safety of elevator passengers.

[0025] Furthermore, the drive sheave 502 is rotatably connected to the protective disc 504. The motor protective housing 4 is bolted to the cable isolation rod 505. There are two groups of cable isolation rods 505. The inner distance of the cable isolation rods 505 is slightly larger than the diameter of the drive sheave 502. The protective disc 504 provides protection for the drive sheave 502 and the elevator steel cables 503, ensuring the cleanliness of the mechanical surface of the winding mechanism 5 and improving the service life of the device. The cable isolation rods 505 are intercepted on both sides of the drive sheave 502, ensuring that the elevator steel cables 503 are transmitted on the inner drive sheave 502 and preventing the elevator steel cables 503 from malfunctioning and coming out of the groove.

[0026] Furthermore, the motor seat 3 is bolted to the central base plate 506. The central base plate 506 is fixedly connected to the buffer springs 507. There are six groups of buffer springs 507. The buffer springs 507 are fixedly connected to the cable chute 508. There are two groups of cable chutes 508. The central base plate 506 and the cable chute 508 constitute a horizontal buffer mechanism through the buffer springs 507. The groove of the cable chute 508 and the elevator steel cable 503 form a sliding structure. The grooves of the cable chute 508 correspond to the elevator steel cables 503 one by one. The central base plate 506 is bolted to the motor seat 3, facilitating maintenance personnel to regularly disassemble and replace the buffer mechanism with a high wear rate at the bottom. The two buffer springs 507 on both sides extrude the two cable chutes 508 outwards, and the two cable chutes 508 extrude the elevator steel cables 503 outwards, keeping the elevator steel cables 503 sliding within the grooves of the cable chute 508. At the same time, it improves the straightness of the elevator steel cables 503, reduces the rope stretching and jitter of the elevator steel cables 503 during the winding process, has a good winding and stretching posture during continuous transmission, prevents the elevator steel cables 503 from coming out of the groove during the winding process, and improves the service life and safety of the elevator steel cables 503.

[0027] Furthermore, the machine room floor 6 and the cable trough 7 are connected by a card slot. There are two sets of cable troughs 7. The elevator steel cable 503 is bent into two sets and passes through the cable trough 7 to be connected to the bottom elevator car and the counterweight. The cable trough 7 enables the elevator steel cable 503 during the winding process to always lift and lower within the specified area, improving the personal safety of elevator maintenance personnel in the machine room.

[0028] Working principle: First, the traction motor 501 starts to drive the driving rope wheel 502 to rotate. The elevator steel cable 503 winds and lifts on the driving rope wheel 502. The driving rope wheel 502 with a larger diameter improves the structural strength of the winding mechanism 5. At the same time, multiple sets of transmission grooves provided on the driving rope wheel 502 are used to wind multiple sets of elevator steel cables 503, increasing the friction force with the elevator steel cable 503, preventing the elevator steel cable 503 from slipping and the driving rope wheel 502 from idling when the driving rope wheel 502 rotates, reducing the probability of elevator lifting failures, and improving the safety of elevator passengers. The protective disc 504 provides a protective effect for the driving rope wheel 502 and the elevator steel cable 503, ensuring the cleanliness of the mechanical surface of the winding mechanism 5 and increasing the service life of the device. Then, the cable isolation rod 505 intercepts on both sides of the driving rope wheel 502 to ensure that the elevator steel cable 503 is transmitted on the inner driving rope wheel 502, preventing the elevator steel cable 503 from malfunctioning and coming out of the groove. The central bottom plate 506 is bolted to the motor seat 3, facilitating maintenance personnel to regularly disassemble and replace the buffer mechanism with a high wear rate at the bottom. Finally, the two buffer springs 507 extrude the two cable chutes 508 outwards. The two cable chutes 508 extrude the elevator steel cable 503 outwards, enabling the elevator steel cable 503 to slide within the groove of the cable chute 508. At the same time, it improves the straightness of the elevator steel cable 503, reduces the rope stretching and jitter of the elevator steel cable 503 during the winding process, and has a good winding and stretching posture during the continuous transmission process, preventing the elevator steel cable 503 from coming out of the groove during the winding process, and improving the service life and safety of the elevator steel cable 503. The main body frame 1 and the fixed shaft seat 2 lift the winding mechanism 5 to a height away from the ground, facilitating elevator maintenance personnel to better monitor, repair, install, and disassemble the winding mechanism 5. The motor seat 3 is used to install the traction motor 501. The motor protection housing 4 is used to protect the traction motor 501, ensuring good ventilation and cooling for the traction motor 501 while preventing foreign objects from falling in and protecting the traction motor 501 from damage. The cable trough 7 enables the elevator steel cable 503 during the winding process to always lift and lower within the specified area, improving the personal safety of elevator maintenance personnel in the machine room. In this way, the working process of an elevator steel wire rope winding anti-slip mechanism is completed.
