AI Technical Summary
The existing pedal mechanism is easily affected by wind and waves when working at the bow, causing it to move laterally, which may prevent it from aligning with the ladder of the offshore platform, or even break, creating safety hazards and reducing operation and maintenance efficiency.
A horizontally movable obstacle avoidance tread for marine use was designed. Through the cooperation of sliding supports and sliding tracks, and by utilizing elastic limit blocks and self-locking hook structures, the tread is ensured to remain aligned with the ladder position during lateral movement, thus preventing breakage.
This effectively prevents the pedal from breaking during lateral movement, ensuring the safety of personnel and equipment and improving the efficiency of offshore operation and maintenance.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pedal technology, specifically relating to a marine lateral movement limit obstacle avoidance pedal. Background Technology
[0002] When transporting maintenance personnel to and from offshore platforms, the most common method is to use bow-to-bow berthing. During this process, berthing bollards and cushioned rubber tires prevent direct collisions between the bow and the platform's ladder. However, this increases the distance between the bow deck and the ladder, causing significant inconvenience and safety hazards for maintenance personnel.
[0003] While conventional stepping mechanisms can reduce the jumping distance for maintenance personnel when passing over ships, in actual operations, maintenance vessels are often affected by wind, waves, and currents, causing them to sway and drift laterally. This results in significant lateral movement between the bow and the ladder, which can cause the stepping boards to fail to align with the ladder on the offshore platform. In some cases, the stepping boards may even break due to impact from the ship's bollard, leading to personal injury accidents for maintenance personnel and reducing the efficiency of offshore maintenance work. Utility Model Content

The sliding support is mounted on the sliding track and slides horizontally. A first elastic limiting block and a first limiting foot are provided on the right side of the mounting base plate, and a second elastic limiting block and a second limiting foot are provided on the left side of the mounting base plate. The tail end of the luffing tread is hinged to the upper surface of the sliding support. A first roller is installed on the bottom right side of the luffing tread, and a second roller is installed on the bottom left side of the luffing tread. The roller rolls on the upper surface of the mounting base plate, the first limiting foot, and the second limiting foot. The torsion spring rod is installed in the front center of the sliding support. The front right side of the sliding support is hinged to the central shaft hole of the first self-locking hook, and the left side of the sliding support is hinged to the central shaft hole of the second self-locking hook. The two ends of the first synchronizing rod are respectively hinged to the lower hinge end of the first self-locking hook and the lower hinge end of the torsion spring rod. The two ends of the second synchronizing rod are respectively hinged to the lower hinge end of the second self-locking hook and the upper hinge end of the torsion spring rod. The luffing pedal is set between the first and second mooring posts. The first and second mooring posts are equipped with ladders.

[0025] The sliding rail 2 is a dovetail groove guide rail, which has strong bearing capacity, is convenient to process and has low cost; the first and second mooring columns 16 and 18 have the same size and specifications, improving interchangeability; the second and first elastic limiting blocks 8 and 7 are symmetrically arranged on the left and right sides of the mounting bottom plate 1; the second and first limiting feet 10 and 9 are symmetrically arranged on the left and right sides of the mounting bottom plate 1; the first elastic limiting block 7 is arranged between the sliding rail 2 and the first limiting foot 9, and the second elastic limiting block 8 is arranged between the sliding rail 2 and the second limiting foot 10, so that the structure is more compact.
[0026] When the overboard personnel is ready to get on the offshore platform from the bow of the ship, the amplitude pedal 4 needs to be stepped on and put down, the amplitude pedal 4 is extruded to the outside of the first and second self-locking hooks 11 and 12, and then falls to the lowest position, and then the first and second self-locking hooks 11 and 12 are reset under the action of the first, second and torsion spring rods 13, 14 and 15, and hook the amplitude pedal 4.
[0027] When the amplitude pedal 4 is put down, the front end of the amplitude pedal 4 will extend into the first and second mooring columns 16 and 18, the first and second mooring columns 16 and 18 can move transversely, assisting the operation and maintenance personnel to climb the ladder 17 between the first and second mooring columns 16 and 18 through the amplitude pedal 4, when the ship moves transversely due to rolling or yawing, the amplitude pedal 4 will be pushed to slide the sliding support 3 on the sliding rail 2 under the action of the transverse force, keeping the amplitude pedal 4 always between the first and second mooring columns 16 and 18.
