Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and more specifically, to a detachable ladder for water conservancy engineering. Background Technology

[0002] Water conservancy projects, as a crystallization of human wisdom in harmonious coexistence with nature, encompass a wide range of fields and complex systems engineering. They aim to effectively manage and utilize water resources through scientific planning and technological means to serve the sustainable development of society and the economy. Specifically, water conservancy projects are not limited to traditional core functions such as flood control, drainage, irrigation, and hydropower generation. They also extensively involve the construction and maintenance of water diversion (supply) systems, tidal flat management to improve the ecological environment, soil and water conservation projects to prevent soil erosion, and the implementation of water resource protection strategies to ensure the cleanliness and safety of water resources. Because urban pipelines are buried underground for extended periods and are affected by various natural factors and human activities, their inspection and maintenance are particularly important and challenging. In this process, ladders, as an indispensable auxiliary tool, play a crucial role.

[0003] A search revealed Chinese patent application number 202320802987.3, which discloses a detachable ladder for water conservancy projects. The ladder includes a ladder frame and a guardrail mechanism. The ladder frame includes a crossbeam, and the guardrail mechanism is provided on the outer surface of the ladder frame. The guardrail mechanism includes a ring guardrail, a support plate, a support tube, a connecting component, and a reinforcing component. The ring guardrail is fitted onto the front surface of the ladder frame, and the inner surface of the ring guardrail is fixed with a support plate. The end of the support plate extends into the support tube, and a connecting component is provided between the two. A reinforcing component is provided on the outer side of the ring guardrail. This invention combines the ladder frame and the guardrail mechanism, allowing adjustment of the distance between two adjacent ring guardrails according to the ladder frame size. This increases the installation and usage range of the ladder frame and improves the safety of maintenance personnel. The entire guardrail mechanism is installed as a whole with screws, making it easy to assemble and disassemble. It also increases the load-bearing capacity of the guardrail mechanism, improving the safety of the ladder frame.

[0004] While the aforementioned patent allows for the disassembly of the circular guardrail for convenient installation and transportation, the following shortcomings still exist during use: 1. Repeated disassembly and assembly of the circular guardrail not only increases workload but may also lead to damage or loss of components, affecting subsequent use and safety; 2. The fixation of the bottom of the ladder is crucial to its stability. If the fixation is not secure or effective fixing measures are lacking, the safety risks during the climbing process will be greatly increased.

[0005] Therefore, there is an urgent need for a detachable ladder for water conservancy projects to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a detachable ladder for water conservancy projects to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A detachable ladder for hydraulic engineering includes two to five sets of ladder bodies hinged together, with adjacent hinges staggered about the ladder bodies. Linear guide rails are fixedly connected to both side walls of each ladder body. Five to twenty sets of annular guardrails are slidably connected to each ladder body via two sets of linear guide rails. Adjacent annular guardrails are connected by evenly distributed protective ropes. Limiting bolts for positioning are provided on both side walls of the top and bottom annular guardrails. A top fixing component is also provided on the top side wall of the ladder body, and a bottom reinforcing component is symmetrically arranged about the central axis of the ladder body on the bottom side wall.

[0009] As a preferred technical solution of this application, the bottom reinforcement component includes a connecting frame fixedly connected to the side wall of the ladder body, a connecting piece rotatably connected to the inner wall of the connecting frame, an adjusting screw rotatably connected to the bottom wall of the connecting piece, a support sleeve sleeve sleeved on the outer wall of the adjusting screw, a support seat rotatably connected to the end of the support sleeve sleeve away from the adjusting screw, and a connecting part rotatably connected to the outer wall of the support sleeve sleeve. The side wall of the support sleeve sleeve is also provided with a first magnetic block.

[0010] As a preferred technical solution of this application, the connecting part includes a first connecting rod fixedly and rotatably connected to the outer wall of the support sleeve rod, a second connecting rod rotatably connected to the end of the first connecting rod away from the support sleeve rod, and the end of the second connecting rod away from the first connecting rod rotatably connected to the ladder body.

[0011] As a preferred technical solution of this application, the outer wall of the adjusting screw is fixedly connected to a handle, the bottom wall of the support base is also provided with an anti-slip pad, and the side wall of the ladder body is also provided with a second magnetic block that matches the first magnetic block.

[0012] As a preferred technical solution of this application, the top fixing component includes a hook fixedly connected to the side wall of the ladder body and symmetrically arranged about the central axis of the ladder body, a mounting rod snapped into the inner wall of the hook, and a mounting seat fixedly connected to both ends of the mounting rod. The top wall of the mounting seat is also provided with a mounting hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. The sliding ring guardrail system allows all ring guardrails to be slid onto the main body of the ladder at the top during transport. When in use, the ring guardrails are unfolded. This sliding ring guardrail system not only solves the space occupation problem of the ladder during transportation, but also improves the efficiency and safety of use through its rapid deployment and flexible adjustment features, avoiding repeated disassembly and assembly.

[0016] 2. By setting up bottom reinforcement components, moving the support sleeve, and rotating the adjusting screw, the support base gradually contacts the ground and presses against the ladder body to fit against the wall, providing stable support for the bottom of the ladder. This stability not only prevents slight swaying during use and enhances the overall stability of the ladder, but also avoids noise and unnecessary wear caused by swaying. More importantly, it provides sufficient resistance in emergency situations (such as wind force, personnel misoperation, etc.) to prevent the ladder from tilting or collapsing, greatly increasing safety during use and reducing potential safety hazards during construction.
