Problems solved by technology

[0004] Although the use of the winch can realize the retraction of the working boat, it has the following disadvantages in the retraction process: (1) the retraction speed is slow, and it needs to be carried out slowly to achieve stable retraction. Cause damage to the hull of the working boat; (2) The operation is troublesome. When retracting and retracting, the hull needs to be fixed in multiple directions before it can be retracted. Generally, at least 4 directions need to be fixed; (3 ) has many restrictions on retraction and deployment. In high sea conditions or when the mother ship is sailing, the workboat cannot be retracted. When the workboat is retrac

Embodiment 1

[0036] Example 1, such as figure 1 , figure 2 , image 3 As shown, this embodiment provides a stern slide type working boat retracting device, which includes a groove 1 arranged obliquely downward on the stern of the hull. The shape of the groove 1 is mainly designed according to the line type of the working boat. In the embodiment, the side wall of the groove 1 is composed of two parts, one part is a vertical downward side wall, another part is an inclined downward side wall, and between the two side walls is a channel of the groove 1. , The width of the channel of the groove 1 is much smaller than the width of the opening of the groove 1, and the line type of the general working boat is also a shape with a wide upper and a narrow bottom. Therefore, the shape of the groove 1 is generally based on the specific working boat. Therefore, the scope of protection of the present invention is not limited to the shape provided by the embodiment of the present invention. The stern door ...

Embodiment 2

[0053] Embodiment 2. This embodiment provides another stern slide type working boat retractable device.

[0054] Considering that 1 to 2 working boats generally need to be placed on the mother ship, in this embodiment, according to real-time requirements, such as Picture 10 , Picture 11 As shown, the difference between this embodiment and embodiment 1 is that two grooves 1 are arranged side by side on the stern part of the hull, and the side walls of the two grooves 1 on the side of the hull are much higher than the two grooves. 1 Adjacent side walls, the height of which is the height of the side walls of the vertical part described in embodiment 1, and the position where two grooves 1 are adjacent to each other, and the guide rail 31 is set on the side wall of groove 1 Above. Of course, two sets of traction devices 3 and two sets of traction slide assembly 4 are also provided. Two sets of stern door slides 5 are set on the stern door 4, and three guides are set on the stern d...

Abstract

The invention belongs to the field of auxiliary equipment of ships and relates to a work boat launching and restoring device, in particular to a stern slipway type work boat launching and restoring device. The stern slipway type work boat launching and restoring device comprises a chute which is obliquely and downwardly arranged on a stern portion of a ship body, the tail end of the chute is movably connected with a stern door, a traction device is arranged on the two sidewalls of the chute, a traction slipway assembly matched with a line type of the work boat is arranged in the chute along the oblique direction of the chute, and a stern door slipway matched with the traction slipway assembly is arranged on the stern door. By arranging the chute on the stern portion and the stern door matched with the chute, a passageway allowing the work boat to go in and go out of the ship body is formed; the traction device arranged on the chute is used for providing power for the work boat to go in/go out; the stern slipway type work boat launching and restoring device is simple in structure, highly reliable, capable of working in severe sea conditions or sailing processes of a mother ship and free from potential safety hazards.

Description

Technical field [0001] The invention belongs to the field of ship auxiliary equipment, and relates to a working boat retracting device, in particular to a stern slide type working boat retracting device. Background technique [0002] When large ships are navigating at sea, in order to make up for the inability of large ships to perform tasks in shallow waters or narrow waters due to low speed and large hulls, it is generally necessary to equip the ships with 1 to 2 high-speed offshore vessels. Small boats are used as work boats to cope with the above shortcomings. [0003] At present, domestic work boats generally use winches for retraction and unwinding. The work boats are hoisted by wire ropes for retraction and unwinding. The work boats are lifted and lowered by winches. The winches generally include motors, couplings, reduction gearboxes, drums, and motors. The gearbox device is connected with the gearbox device through the coupling, the gearbox device and the reel are connect...
