Description

Technical Field

[0001] This utility model relates to the field of elevator speed governors, and in particular to an elevator speed governor tensioning and anti-jump device. Background Technology

[0002] Elevator speed governors are usually important components of elevator safety protection systems. They ensure that the elevator can brake in time when it is overspeeding to prevent accidents, while also monitoring and controlling the speed of the elevator car.

[0003] Existing elevator speed governors typically include a speed governor body and a tensioning anti-jump device. An elevator rope is installed between the speed governor body and the tensioning anti-jump device. The tensioning anti-jump device includes a tension wheel, a support frame, and a counterweight. The tension wheel is slidably mounted on the support frame, and the counterweight performs a counterweight operation on the tension wheel to provide tensioning and anti-jump protection for the elevator rope.

[0004] When a rope moves on a tensioning pulley, friction is generated. In order to protect the rope from wear, a quantitative lubrication operation is usually performed. Existing technology usually requires personnel to apply lubricant to the rope, but this method is cumbersome. Therefore, it is necessary for the tensioning and anti-jump device of the elevator speed limiter to automatically lubricate the rope on the tensioning pulley. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] This utility model provides, for example Figure 1-4 The image shows an elevator speed governor tensioning anti-jump device.

[0042] Example 1

[0043] The system includes a speed governor body 1, a sliding frame 3, and an auxiliary mechanism 5. The speed governor body 1 and the tension wheel 4 are arranged vertically opposite each other and installed on the side of the elevator car. The rope is connected to the side of the elevator car. The sliding frame 3 helps to support the tension wheel 4 and facilitates its vertical guidance. A support frame 2 is provided below the speed governor body 1. The support frame 2 is U-shaped, which facilitates the installation of the sliding frame 3 and the tension wheel 4. The tension wheel 4 is rotatably installed inside the support frame 2, which helps to tension the rope and prevent it from jumping. A rope is provided between the speed governor body 1 and the tension wheel 4. The sliding frame 3 is sleeved on the tension wheel 4 and is slidably installed on the support frame 2. The auxiliary mechanism 5 is located inside the support frame 2 and is used for automatic quantitative lubrication of the rope.

[0044] Furthermore, the auxiliary mechanism 5 includes a limiting frame 51, a cavity, oil-absorbing cotton 55, a driving component, and a supporting component. The limiting frame 51 is U-shaped and helps to prevent the rope from jumping and detaching from the tension wheel 4. It also facilitates the sliding of the oil-absorbing cotton 55 on it. The cavity is conducive to storing lubricating oil. The application of lubricating oil to the oil-absorbing cotton 55 requires a quantitative and time-limited setting to prevent over-application. The oil-absorbing cotton 55 can penetrate into the interior of the lubricating oil to absorb it. An elastic body can be installed at the bottom of the oil-absorbing cotton 55 and driven by the driving rod 58. This allows the oil-absorbing cotton 55 to be in an expanded state inside the cavity to absorb lubricating oil. When the rope is being lubricated, the elastic body squeezes the oil-absorbing cotton 55 from the bottom so that the lubricating oil is squeezed onto the rope, thus achieving the lubrication operation. The limiting frame 51 is sleeved on the outside of the tensioning wheel 4, and the cavity is opened inside the limiting frame 51. The oil-absorbing cotton 55 is slidably disposed inside the limiting frame 51, and the oil-absorbing cotton 55 is slidably inserted into the inner cavity of the cavity. The oil-absorbing cotton 55 is located at the bottom of the rope, the driving component is located at the bottom of the limiting frame 51, and the support component is located on the limiting frame 51. The support component is used to connect the oil-absorbing cotton 55 to the driving component.

[0045] Furthermore, the auxiliary mechanism 5 also includes a connecting pipe 56 and a fixing member. The connecting pipe 56 facilitates the addition of lubricating oil into the cavity. The connecting pipe 56 is fixedly inserted and connected to the side of the limiting frame 51, and the fixing member is located inside the support frame 2.

[0046] Specifically, the support components include a fixed head 57, a drive rod 58, an adhesive plate 59, a collection frame 510, and a connecting post 511. The fixed head 57 helps to support the oil-absorbing cotton 55, facilitating its vertical driving operation. The drive rod 58 helps to move the fixed head 57 to drive the oil-absorbing cotton 55 vertically up and down, allowing for its storage and use. The adhesive plate 59 helps to seal the bottom of the cavity wall after the oil-absorbing cotton 55 is stored, preventing lubricating oil leakage. The collection frame 510 helps to collect and store lubricating oil that leaks from the limiting frame 51. The connecting post 511 is beneficial for supporting the limiting frame 51 for installation, and also for guiding and supporting the sliding of the drive rod 58. The fixing head 57 is fixedly connected to the bottom of the oil-absorbing cotton 55, and the end of the drive rod 58 is fixedly connected to the bottom of the fixing head 57. The outer wall of the drive rod 58 is slidably inserted into the limiting frame 51. The fitting plate 59 is fixedly sleeved on the outside of the drive rod 58. The collecting frame 510 is fixedly connected to the other end of the drive rod 58. The connecting post 511 is fixedly connected to the bottom of the limiting frame 51, and the outer wall of the drive rod 58 is slidably inserted into the connecting post 511.

[0047] Specifically, the driving components include an electric push rod 512 and a support frame 513. The electric push rod 512 is electrically connected to an external power source via an external switch. The electric push rod 512 facilitates the automatic movement of the collection frame 510 to automatically drive the oil-absorbing cotton 55, which is convenient for lubricating the rope, saving manpower, and optimizing the operation steps. The support frame 513 is U-shaped, which is beneficial for supporting the electric push rod 512 and facilitating its installation. The electric push rod 512 is located at the bottom of the collection frame 510, and its output end is connected to the collection frame 510 for transmission. The support frame 513 is fixedly sleeved on the outside of the electric push rod 512.

[0048] Example 2

[0049] Based on Embodiment 1, the fastener includes an assembly plate 52, a fixing seat 53, a threaded post 54, and an assembly ring. The assembly plate 52 facilitates the support of the connecting post 511 for installation. The fixing seat 53 and the threaded post 54 facilitate vertical positioning of the assembly plate 52. The assembly ring facilitates locking and fixing the threaded post 54, making it easy to install and disassemble the assembly plate 52 and use it as needed. The assembly plate 52 is fixedly sleeved on the outside of the connecting post 511. The bottom of the assembly plate 52 is fixedly connected to the support frame 513. The fixing seat 53 is fixedly connected to the inner wall of the support frame 2. The threaded post 54 is fixedly connected to the top of the assembly plate 52. The outer wall of the threaded post 54 is slidably inserted into the inner cavity of the fixing seat 53. The assembly ring is threadedly inserted into the outside of the threaded post 54.
