Description

Technical Field

[0001] This utility model belongs to the technical field of boiler maintenance engineering, and in particular relates to a device for detecting slack in the working wire rope of a boiler inspection platform. Background Technology

[0002] With the rapid development of my country's economy and the continuous improvement of chemical technology, the number of boiler factories is increasing daily. These boiler factories were built in different historical periods. Due to long-term use and the influence of environmental factors, some boilers have shown significant performance degradation. Therefore, comprehensive overhaul is urgently needed, as it is crucial to ensure boiler efficiency and safe operation.

[0003] Currently, boiler maintenance is typically carried out using a boiler maintenance platform. However, while existing boiler maintenance platforms are equipped with fall protection devices, these devices have a problem: even if the working wire rope is not broken, the fall protection can still be accidentally triggered. When the fall protection of a multi-point boiler maintenance platform is triggered on only one of the points, the untriggered points will continue to descend, causing the platform to tilt. In this situation, personnel on the platform often need to rely on their perception of the platform's tilt to determine if any individual points have triggered the fall protection. If personnel fail to detect this in time, a certain safety risk exists. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a slack rope detection device for the working wire rope of a boiler inspection platform. It is adaptable to most climbing boiler maintenance platforms. During the platform's lifting and lowering process, a limit switch triggers protection, automatically stopping the platform to protect both the platform and the personnel on it. The device boasts advantages such as simple overall structure, easy installation, and good economic efficiency. It solves the problem in the prior art where, when the fall protection of a multi-point boiler maintenance platform is triggered individually, the untriggered lifting points continue to descend, causing the platform to tilt. Relying on the worker's perception of tilt in such situations can easily lead to accidents due to negligence, posing a safety risk.

[0005] This utility model is implemented as follows: a slack rope detection device for a boiler inspection platform's working wire rope, comprising a lifting equipment assembly and a detection assembly. The lifting equipment assembly includes a lifting machine body and a mounting frame for mounting the detection assembly and adapting it to the boiler maintenance platform. The detection assembly includes a vertical pipe, a limit switch, a roller clamping plate, a lead screw, a spring, a bushing, a roller sleeve, and a roller body. The vertical pipe is vertically connected to the mounting frame of the lifting equipment assembly, serving as a support structure for the detection assembly. The limit switch is mounted on the vertical pipe and is subject to... A stop signal is output upon triggering; the roller clamp is movably connected to the vertical pipe via a bushing, and its displacement changes with the tension of the wire rope; the lead screw passes through the roller clamp and is connected to a spring to adjust the initial tension; the spring is sleeved on the lead screw and drives the roller clamp to move through elastic deformation; the bushing is used to ensure that the roller clamp slides smoothly along the vertical pipe; the roller sleeve is sleeved on the roller body to assist in guiding the wire rope; the roller body is installed between the inner ends of the roller clamp via the roller sleeve and is in close contact with the working wire rope.

[0006] This design is compatible with most climbing boiler maintenance platforms. During the platform's lifting and lowering process, the limit switch is triggered for protection, and the platform automatically stops to protect the platform and the personnel on it. The overall structure is simple, easy to install, and economical.

[0007] As a preferred embodiment of this invention, the spring is a cylindrical helical compression spring, which is suitable for steel wire ropes with different tensions.

[0014] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0015] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] refer to Figures 1 to 2 As shown in the figure, this utility model provides a boiler inspection platform working wire rope slack detection device, including a lifting equipment assembly 1 and a detection assembly. The lifting equipment assembly 1 includes a lifting machine body 101 and a mounting frame 102, which is used to mount the detection assembly and is adapted to the boiler maintenance platform. The detection assembly includes a vertical pipe 2, a limit switch 3, a roller clamping plate 4, a lead screw 5, a spring 6, a bushing 7, a roller sleeve 8, and a roller body 9. The vertical pipe 2 is vertically connected to the mounting frame 102 of the lifting equipment assembly 1, serving as a support structure for the detection assembly. The limit switch 3 is installed on the vertical pipe. 2. When triggered, a stop signal is output; the roller clamp 4 is movably connected to the vertical tube 2 through the bushing 7, and its displacement changes with the tension of the wire rope; the lead screw 5 passes through the roller clamp 4 and is connected to the spring 6, which is used to adjust the initial tension; the spring 6 is sleeved on the lead screw 5 and drives the roller clamp 4 to move through elastic deformation; the bushing 7 is used to ensure that the roller clamp 4 slides smoothly along the vertical tube 2; the roller sleeve 8 is sleeved on the roller body 9 to assist in guiding the wire rope; the roller body 9 is installed between the inner ends of the roller clamp 4 through the roller sleeve 8 and is in close contact with the working wire rope.

[0017] The above solution can be adapted to most climbing boiler maintenance platforms. During the platform's lifting and lowering process, the limit switch 3 is triggered for protection, and the platform automatically stops to protect the platform and the personnel on it. The overall structure is simple, easy to install, and economical.

[0018] Specifically, the spring 6 is a cylindrical helical compression spring 6, which is adapted to steel wire ropes with different tensions.

[0019] Specifically, the roller body 9 is made of nylon, and the U-shaped groove on its surface is adapted to the diameter of the steel wire rope to prevent slippage.

[0020] Specifically, the mounting bracket 102 of the lifting equipment component 1 is provided with threaded mounting holes for mounting the vertical pipe 2.

[0021] The working principle of this utility model: In use, the working wire rope passes through the hoist in the lifting equipment component 1, and the protective wire rope passes through the safety lock. When the safety lock is triggered to lock the rope during platform operation, the working wire rope will be in a loose state as the platform continues to descend. At this time, the tension on the spring 6 decreases and slowly extends, pushing the roller clamp 4 to move along the vertical pipe 2 towards the limit switch 3, so that the roller clamp 4 touches the limit switch 3, preventing the platform from continuing to descend, avoiding platform tilt and causing accidents, and protecting the platform and the safety of the workers on the platform.

[0022] This device eliminates the need for human judgment, automatically monitoring and triggering shutdown via mechanical structure. Limit switches are activated the instant the rope is released, far faster than manual reaction time, ensuring timely response and significantly improving safety reliability. It reduces safety risks at the source, adaptable to steel wire ropes with varying tension requirements, and compatible with most climbing boiler maintenance platforms. It boasts high adaptability and flexibility, a simple overall structure, easy installation, and low maintenance costs, making it suitable for mass application in industrial settings. During platform lifting, limit switches trigger protection, automatically stopping the platform to protect both the platform and personnel on it. The overall structure is simple and easy to install.
