Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ship ladders, in particular to a ship ladder. Background Art
[0002] A pilot is a person who guides ships to navigate safely, berth or leave docks, or pass through locks and other restricted waters in a certain navigation area. When a pilot receives a task, he first takes a shuttle boat to approach the ship that needs to be piloted. The crew drops a soft ladder for the pilot to safely board and leave the ship. The pilot needs to climb the ladder to the bridge and give commands to the ship to enter and leave the port. In the process of climbing the ship, the pilot faces various uncertain weather conditions at any time, especially big waves, typhoons and other severe weather, which is very dangerous.
[0003] When encountering continuous big waves, the pilot holds the ropes on both sides of the ladder with both hands to improve his own stability and waits for the sea surface to stabilize before continuing. However, long-lasting big waves will cause great physical loss to the pilot, and the insufficient friction between the pilot's feet and the ladder pedals may easily cause the pilot's feet to separate from the pedals, aggravating the pilot's panic and increasing safety risks. Utility Model Content

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.
[0017] like Figure 1-3 As shown, a soft ladder for boarding and disembarking a ship comprises a plurality of pedals 1, mounting seats 2 are respectively arranged on the upper and lower sides of both ends of the pedals 1, and also comprises a rope 3 for connecting two adjacent pedals 1, and the two ends of the rope 3 are respectively fixedly connected to the mounting seats 2 on the adjacent pedals 1, and a limiting component is arranged in the middle of the upper surface of the pedal 1, and the limiting component comprises a vertical plate 4, and the vertical plate 4 is fixed to the pedal 1 by bolts, and hook plates 5 are respectively arranged on both sides of the upper end of the vertical plate 4, and the distance between the end of the hook plate 5 away from the vertical plate 4 and the upper surface of the pedal 1 is smaller than the distance between the other end of the hook plate 5 and the upper surface of the pedal 1, and the inner side surface of the hook plate 5 close to one end of the vertical plate 4 is provided with a needle 6, and the width of the hook plate 5 is smaller than the width of the pedal 1.
[0018] The pedal 1 is made of wood or aluminum alloy. The pedal 1 is used for the pilot to step on. There is a cross bar in the middle of the mounting seat 2. The two ends of the rope 3 pass through the cross bar in the mounting seat 2 and form a ring. The rings at both ends of the rope 3 are then fixed so that the rope 3 cannot be separated from the cross bar, thereby completing the installation and fixation of adjacent pedals 1.
[0019] When the pilot goes up or down the ladder, he or she grasps the ropes 3 on both sides of the ladder with both hands, and then moves through the pedal 1 to get on or off the hull. When the pilot encounters long waves on the ladder, the safest way is to stop moving and hold the rope 3, wait for the waves to pass, and then move after the ladder is stable. However, when the waves hit the hull, seawater will flow over the pedal 1, resulting in a decrease in the friction between the pilot's feet and the pedal 1. At the same time, when encountering long waves, the pilot needs to keep his or her feet attached to the pedal 1 at all times. Due to the long time, the pilot's physical strength is greatly consumed, which puts the pilot in a more dangerous environment. In the case of a long period of sea wave turbulence, the pilot can hold the rope 3 with both hands, and the two feet can approach the vertical board 4 respectively, and put the feet into the hook board 5. After the feet enter the hook board 5, the instep is arched, and the upper surface of the shoe collides with the inner upper surface of the hook board 5. During the collision, the needle 6 will penetrate into the shoe surface. The arch of the instep and the action of the needle 6 can provide sufficient friction for the pilot's shoes, so that the pilot can reduce the loss of physical strength while waiting for the waves to pass, and avoid the risk of physical weakness caused by sticking the feet to the pedal 1 for a long time.
[0020] The pilot can also lift up the instep, hook the hook plate 5 with the instep, and cooperate with the needle 6. Compared with simply standing on the pedal 1, it can also effectively reduce the pilot's physical strength consumed in maintaining stability on the pedal 1. By arching or lifting the instep, the pilot can change the posture of the foot at any time to prevent soreness and discomfort in the foot caused by maintaining a certain posture for a long time.
[0021] Furthermore, both ends of some pedals 1 are extended, and at least one pedal 1 of normal length is provided between the two extended pedals 1. By extending the pedals 1, the anti-twisting ability of the soft ladder can be improved, thereby facilitating the protection of the pilot on the soft ladder.
[0022] Furthermore, the pedal 1 has a first surface 7 and a second surface 8, the second surface 8 of the pedal 1 faces the hull, the hook plate 5 has a third surface 9 and a fourth surface 10, the fourth surface 10 of the hook plate 5 faces the hull, the shortest distance between the third surface 9 and the first surface 7 is greater than the shortest distance between the fourth surface 10 and the second surface 8, and the shortest distance between the fourth surface 10 and the second surface 8 is greater than zero, the distance between the first surface 7 and the third surface 9 is used to accommodate the pilot's ankle, when the pilot's shoe enters under the hook plate 5, the pilot's heel abuts against the upper side edge of the first surface 7, the distance between the second surface 8 and the fourth surface 10 is used to accommodate the pilot's forefoot, to prevent the distance between the second surface 8 of the pedal 1 and the hull from being too close, resulting in the pilot's shoe being unable to effectively enter under the hook plate 5, the position of the hook plate 5 corresponds to the position of the instep, so that the shoe at the instep can be better connected to the needle 6 on the hook plate 5.
[0023] Furthermore, the upper surface of the pedal 1 is located in the treading area between the adjacent mounting plate and the hook plate 5, and the width of the treading area is greater than the width of the area below the hook plate 5. When the pilot uses the soft ladder normally, he can go up and down the soft ladder normally through the treading area on the pedal 1. Since the treading area is a commonly used area and the area below the hook plate 5 is not commonly used, the width of the treading area is greater than the width of the area below the hook plate 5, which can improve the comfort and convenience of the pilot in using the soft ladder under normal sea conditions.
[0024] Furthermore, one end of the hook plate 5 away from the vertical plate 4 is arranged to be arc-shaped, so as to facilitate the rapid squeezing of the shoes on the feet into the hook plate 5 .
[0025] The device can provide greater friction for the pilot's feet through the hook plate 5 and the needles on the hook plate 5, reduce the loss of physical strength during the long period of waiting for the waves to stabilize, and make it easier for the pilot to climb on the soft ladder stably for a longer period of time. It also makes it easier for the pilot to have sufficient physical strength to get off the soft ladder after the waves are relatively stable, thereby reducing safety hazards.
