Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship technology, in particular to a soft ladder winch device. BACKGROUND

[0002] When a ship enters or exits a port, the local maritime department requires a pilot to guide the ship to enter or exit the port. However, the specification requires that the ship be equipped with a pilot boarding and disembarking device on both sides to effectively achieve the purpose of safely boarding and disembarking the pilot. The boarding and disembarking device is generally composed of an aluminum gangway and a pilot soft ladder. When the distance between the sea level and the deck of the ship is less than 9 meters, the pilot soft ladder is directly placed, and the pilot climbs on the ship. When the distance between the sea level and the deck of the ship is greater than 9 meters, the pilot soft ladder and the aluminum gangway are used in cooperation. Therefore, the ship is equipped with a pilot soft ladder.

[0003] Generally, the pilot soft ladder is arranged on the main deck close to the side of the ship. The soft ladder is not used when the ship is sailing, and is stored in a storage seat near the gangway. When the ship enters or exits the port, the crew places the pilot soft ladder close to the outer plate of the side of the ship, so that the pilot can climb on the ship. Because the soft ladder is heavy, manual recovery is low in efficiency and difficult. Generally, an electric winch is provided on the main deck to realize the winding and unwinding of the pilot soft ladder by using electric detection. However, the width of the channel on the main deck is effective, and the conventional electric winch occupies the channel space after recovering the soft ladder, which affects the width of the escape channel of the ship. In addition, the soft ladder itself protrudes from the side of the ship body, so that the soft ladder is easily damaged. SUMMARY

[0034] The specific embodiments of the present application will be described in further detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0035] Please combine Figs. 1 to 4 The embodiment of the present application provides a soft ladder 50 winch device, which comprises a vertical beam 10, a winch assembly 30 and a guide 40.

[0036] Specifically, the vertical beam 10 is fixed on the main deck 60 in the vertical direction, and the vertical beam 10 is provided with a fixing piece 20 for fixed connection with one end of the soft ladder 50; the winch assembly 30 comprises a power piece 32, a winding drum 33 and two brackets 31 symmetrically arranged in the vertical direction, the lower end of the bracket 31 is fixedly connected with the main deck 60, and a storage space for storing the soft ladder 50 is defined between the bracket 31 and the vertical beam 10, the winding drum 33 is rotatably arranged between the two brackets 31, the power piece 32 is installed on the top of the bracket 31, and the power output end of the power piece 32 is connected with one end of the winding drum 33, a plurality of protruding guide plates 90 are circumferentially and interval ly distributed on the barrel of the middle part of the winding drum 33, and under the condition that the winding drum 33 is driven to rotate, the plurality of guide plates 90 alternately abut against the steps of the soft ladder 50 to pull the soft ladder 50 to move, thereby realizing the recovery or lowering of the soft ladder 50. The guide 40 is arranged at the front end of the main deck 60 for guiding the soft ladder 50.

[0037] Illustratively, the power piece 32 can be a motor, the free end of the soft ladder 50 is lapped on the winding drum 33, and then the motor is used to drive the winding drum 33 to rotate, so that the winding drum 33 can pull the soft ladder 50 to move, thereby realizing the automatic lowering of the soft ladder 50 without manual operation, which is beneficial to reduce the labor intensity. The power piece 32 adopts a motor, which is only an example, but is not limited thereto, and the power piece 32 can also be other power components capable of driving the winding drum 33 to rotate.

[0038] It should be noted that, since the soft ladder 50 is provided with the stepping plates for the waterman to step on, in order to realize the pulling of the soft ladder 50 and avoid the relative sliding of the soft ladder 50 during the pulling, when the free end of the soft ladder 50 is lapped on the winding drum 33, it is necessary to ensure that the guide plates 90 on the winding drum 33 are clamped between the adjacent stepping plates of the soft ladder 50, so that the power member 32 can drive the winding drum 33 to rotate.

[0039] Exemplarily, the above-mentioned "multiple" refers to two or more, which needs to be determined according to the actual situation, for example, in order to ensure that the soft ladder 50 is pulled more stably to avoid jumping, four guide plates 90 are distributed on the barrel of the winding drum 33, when the power member 32 drives the winding drum 33 to rotate, the guide plates 90 on the winding drum 33 are driven to alternately rotate, since the soft ladder 50 is clamped into a guide plate 90 every adjacent stepping plate, so that the guide plates 90 alternately and orderly pull the soft ladder 50 during the rotation of the winding drum 33, which ensures that the soft ladder 50 is more stably lowered or recovered.

[0040] Exemplarily, during the lowering or recovery of the soft ladder 50, the soft ladder 50 will contact the front end of the main deck 60, and then rub to cause damage, in the embodiment, the guide member 40 is arranged at the front end of the main deck 60, so as to avoid the contact between the soft ladder 50 and the front end of the main deck 60, which can effectively avoid the friction damage to the soft ladder 50. It should be noted that the guide member 40 can be a guide wheel, or other guide components in the prior art which can avoid the contact between the soft ladder 50 and the main deck 60, which is not limited.

[0041] Exemplarily, in order to avoid the disorder of the soft ladder 50 when it is recovered to the storage space, which causes the subsequent problem of disorderly lowering, a storage rack can be arranged in the storage space to orderly stack the soft ladder 50.

[0042] Exemplarily, during the use of the soft ladder 50 by the waterman, the winding drum 33 needs to be locked to avoid the relative rotation of the winding drum 33 during the use, which affects the safety of the waterman. It should be noted that the locking of the winding drum 33 can adopt a stop pin, and how the stop pin is used to limit the rotation of the winding drum 33 is a common knowledge, which can be referred to the prior art, and will not be described here.

[0043] The soft ladder 50 winch device based on the above technical features fixes the fixed end of the soft ladder 50 to the fixed part 20, and then overlaps the free end of the soft ladder 50 on the winding drum 33, so that the guide plate 90 on the winding drum 33 is clamped between the adjacent steps of the soft ladder 50, and then the winding drum 33 is rotated under the driving of the power part 32 to drive the guide plate 90 to orderly pull the soft ladder 50 to move, so that the soft ladder 50 stored in the storage space is lowered to the water surface, and the soft ladder 50 is ingeniously stored in the inside of the passage of the main deck 60. Compared with the traditional way of winding the soft ladder 50 on the winding drum 33, the passage space can be effectively reduced, the problem of damage of the soft ladder 50 protruding from the hull side can be avoided, and the impact of the sea wave on the soft ladder 50 during the navigation of the ship can be better prevented, and the service life is improved.
