Description

Technical Field

[0001] This utility model relates to the field of docks, and in particular to a movable dock railing. Background Technology

[0002] In traditional dock operations, winch tracks are typically installed around the parapet wall area. During actual production, workers sometimes stand above these tracks to observe operations within the dock, posing a significant risk of falls from height and mechanical injuries, resulting in substantial safety hazards.

[0003] The commonly used protective measure is to install fixed railings on the parapet structure. However, traditional fixed railings are rigidly connected to the dock parapet with expansion bolts, which has significant drawbacks in practical applications: First, when a ship needs to be launched and the winch is used for cable-laying operations, part of the railing must be removed. The fixed structure makes the disassembly and assembly process time-consuming and labor-intensive, seriously affecting operational efficiency. Second, repeated disassembly and assembly not only increases labor costs but also damages the dock structure. Third, this fixing method not only makes the railings non-removable and unable to flexibly adapt to the safety protection needs of different operational stages, but also causes irreversible damage to the internal structure of the parapet, which is not conducive to the long-term maintenance and structural integrity of the dock facilities. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dock movable railing that can reduce the safety risks in the area surrounding the dock and is easy to disassemble.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a dock movable railing, the innovation of which is: including a number of transition railings and hand-operated railings installed on the parapet wall of the dock; The transition railing includes a first fixing member and a first railing. The first fixing member is a U-shaped channel steel structure and is fixed to the parapet wall by bolts and nuts. The first railing is fixed to the side of the first fixing member. The handrail includes a second fixing member and a second railing. The second railing includes a second main railing and a second secondary railing. The second fixing member is a U-shaped channel steel structure and is fixed to the parapet wall by bolts and nuts. The second fixing member includes a second main fixing member connected to the second main railing and a second secondary fixing member connected to the second secondary railing. The second main railing and the second main fixing member are connected by bolts and nuts. One side of the second secondary railing is hinged to the second secondary fixing member, and the other side is hinged to the second main railing. The second main railing is also equipped with a ring, and a protective steel wire rope is installed between the rings of adjacent second main railings. The two sides of the protective steel wire rope are fixed to the ring by the cooperation of the rigging spiral buckle and the rope clamp. A limiting ring for the protective steel wire rope to pass through is also installed at the top of the first railing.

[0006] Furthermore, the first railing is fixed to the first fixing member by bolts and nuts, and the second main railing is fixed to the second main fixing member by bolts and nuts.

[0007] Furthermore, among the handrails described, the handrails located at the end of the parapet wall have one second auxiliary railing connected to the side of the second main railing near the center of the parapet wall; the handrails located at the remaining positions of the parapet wall have two second auxiliary railings connected to the two sides of the second main railing in a figure-eight shape.

[0008] Furthermore, warning layers are also provided on the outer walls of the first and second railings.

[0009] The advantages of this utility model are as follows: The movable railing of this utility model is connected to the parapet wall by the cooperation of the fixing parts and the railing. It is convenient to disassemble and maintain. It can be quickly removed by simply removing the connecting bolts and nuts. It can ensure the stability and lightness of the structure without damaging the dock parapet wall, and also ensure the convenience of disassembly and installation.

[0010] The design of the warning layers on the first and second railings enhances the warning effect.

[0011] The movable railing of this utility model, through its modular design and detachable connection, effectively reduces the safety risks to workers in the area surrounding the dock while ensuring that the normal operation of the dock is not affected. It has significant safety protection value and engineering practicality. Attached Figure Description
