Description

Technical Field

[0001] The utility model relates to the technical field of elevator safety monitoring, in particular to an elevator steel rope breakage monitoring device. Background Art

[0002] An elevator's wire rope is a critical load-bearing component, and its safety is directly related to the safety of passengers and cargo. A broken wire in the wire rope, especially during operation, can cause the elevator to suddenly stop, fall, or lose control, leading to serious accidents.

[0003] Since the elevator wire rope is long and perpendicular to the elevator shaft, inspectors need to inspect along the entire length of the wire rope, which makes the inspection process relatively cumbersome and dangerous. In addition, the elevator wire rope needs to be inspected 360 degrees, which makes the inspection process more difficult.

[0004] Therefore, in view of the fact that the length of the elevator wire rope perpendicular to the elevator shaft is long and 360-degree detection is required, which makes the inspection process of the elevator wire rope difficult and dangerous, an elevator wire rope broken wire monitoring device can be designed to solve the above problem.

[0023] See also Figure 2-Figure 4 In this embodiment, the first shell 2 and the second shell 3 are rotatably connected by a hinge at the rear end. A first inner shell 501 is installed in the first shell 2, and a second inner shell 502 is slidably connected in the second shell 3. Two rotating wheels 503 are rotatably connected in the first inner shell 501 and the second inner shell 502. The outer sides of the rotating wheels 503 are fixedly connected with soft sleeves 504, and the soft sleeves 504 are provided with curved grooves 505. A plurality of protruding ribs 506 are fixed in the curved grooves 505. The rotating wheels 503 located at the upper end of the first inner shell 501 are connected with a first motor 507, and the first motor 507 is installed on the front end surface of the first shell 2. The other sides of the two rotating wheels 503 in the first inner shell 501 are fixed with synchronous wheels 509, and the synchronous wheels 5 09 are both located at the rear end of the first shell 2, and a synchronous belt 510 is connected to the synchronous wheel 509 for common rotation. An electric push rod 508 is connected to one side of the second inner shell 502, and the electric push rod 508 is installed on one side of the second shell 3. The upper ends of the first shell 2 and the second shell 3 are both fixed with a T-shaped semicircular rail 601, and a semicircular sleeve 602 is slidably connected to the T-shaped semicircular rail 601. The lower ends of the semicircular sleeve 602 are provided with a tooth groove 603. A second motor 606 is installed at the rear end of the second shell 3, and a gear 605 is connected to the upper end of the second motor 606. The gear 605 is engaged with the semicircular sleeve 602 through the tooth groove 603. A fixed platform 604 is fixed to the semicircular sleeve 602 on one side, and the camera 1 is fixed to the fixed platform 604.

[0024] When in use, after opening and placing the steel wire rope inside the first outer shell 2 and the second outer shell 3, the first outer shell 2 and the second outer shell 3 are locked by the buckle 4, and then the electric push rod 508 pushes the second inner shell 502 so that the rotating wheel 503 and the soft cover 504 clamp the two sides of the steel wire rope. The soft cover 504 increases the fit between the rotating wheel 503 and the steel wire rope, and the protruding ribs 506 increase the friction force, so that the device can be used for steel wire ropes of different thicknesses;

[0025] Subsequently, the first motor 507, the synchronous wheel 509, and the synchronous belt 510 rotate the rotating wheel 503 on one side, thereby causing the device to be raised and lowered on the wire rope;

[0026] At the same time, the second motor 606 rotates the two semicircular sleeves 602 via the gear 605, allowing the camera 1 and the fixed platform 604 to rotate around the wire rope when the device is raised or lowered. This allows the camera 1 to capture 360-degree images or video information of the wire rope. The camera 1 transmits the information to the inspector's terminal, who then determines the health of the wire rope.

[0027] In addition, the device can be hung on the elevator wire rope for a long time, so that the monitor can use the device to check the elevator wire rope periodically to achieve long-term monitoring.

[0028] Through the above steps, by setting up the adjustable lifting component and the rotating shooting component, the device can clamp steel wire ropes of different specifications and be lifted and lowered on the steel wire ropes. At the same time, the camera 1 can also rotate around the steel wire rope when the device is lifted and lowered, so that the camera 1 can obtain 360-degree pictures or video information of the steel wire rope, thereby reducing the risk of elevator steel wire rope detection through remote monitoring and reducing the difficulty of detection through rotating shooting.
