Abstract

The utility model discloses a hoisting device of small guard boats. Guard boats can not be timely hoisted by the existing supralittoral hoisting machines, and occasion for fire protection and patrol is delayed to cause passive work, so the hoisting device of small guard boats is provided to overcome the problems. An upright post is fixed on a boat body. The upright post is sheathed with a rotary disk which can rotate around the upright post. One end of a hoisting rod is hinged on the rotary disk. A steel rope installed on a windlass on the boat passes round the upper part of the rotary disk, a fixed pulley on the free end of the hoisting rod and a movable pulley on a hoisting hook on the lower part of the free end of the hoisting rod. An end head is fixed on the free end of the hoisting rod. When the utility model is used, people can put guard boats on the boat body to water without use of supralittoral hoisting machines and time spent on finding right positions, people only operate the rotary disk and the windlass and other operations are completely completed by the utility model. The utility model has the advantages of good time saving capability, good labor saving capability and reliable use. The utility model can also ensure the safety of both guard boats and people and can satisfy the needs of emergency patrol.

Description

The patrol small lifting appliance

Technical field

The utility model belongs to lifting tool, specifically a kind of lifting appliance with patrol small waterborne.

Background technology

The patrol small that fire-fighting waterborne is used, for example on the deck of the fire fighting ship of the band patrol small of using on the sea port dock, generally lay the patrol small that to carry out flexible patrol, in case when needing that water is executed the task under the guard boat, need employ on the bank that loop wheel machine is put into water with guard boat or guard boat be sling by water and be put on the fixed mount of fire fighting ship with loop wheel machine on the bank.The said method impropriety is: because when using on the bank loop wheel machine, want earlier loop wheel machine to be reached the correct position that the bank can be hung guard boat and guard boat be put into water, therefore can not in time guard boat be put in the water or from water and sling, incur loss through delay the best opportunity of fire patrol work, it is passive to cause to work.

The utility model content

Technical problem to be solved in the utility model is, overcomes the existing usefulness loop wheel machine on the bank guard boat of can not in time slinging, and incurs loss through delay fire patrol and causes opportunity passively to work, and a kind of patrol small lifting machine is provided.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: be fixed with column on hull, be with the rotating disk that can rotate around it on the column, an end of suspension rod is hinged on rotating disk; Installation winch steel rope is aboard ship walked around the movable pulley on rotating disk top and free-ended fixed pulley of suspension rod and the suspension rod free end bottom suspension hook, and the free end of suspension rod is fixed in the termination.

The utility model also has following technical characterictic:

Between the free end of suspension rod and rotating disk, be connected with the location pulling rope.

In the time the guard boat above the hull need being put in the water, rotate rotating disk and make guard boat above the suspension hook subtend hull of suspension rod free end bottom, put down the lifting rope that suspension hook catches on guard boat; Start winch, steel rope is sling guard boat by each fixed pulley and movable pulley, and rotary turnplate makes the guard boat subtend water surface of slinging again, and the backward rotation winch loosens steel rope, and guard boat will steadily be put on the water surface.

Advantage of the present utility model and good effect are, owing to from ship, guard boat is put down water, do not use loop wheel machine on the bank, do not spend the time of centering position yet, only need to be installed on people's management of a ship suspension rod and winch work on the column rotating disk, can finish lifting, the transposition of guard boat and transfer, time saving and energy saving saving of labor, use reliably, can guarantee man-machine safety, the needs when satisfying emergent the patrol.

Description of drawings

Fig. 1 looks scheme drawing for master of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1,, be installed with column 9 at the afterbody of hull 1, the useful bearing of cover supporting on the column 9, the rotating disk 12 that can rotate around column 9, rotating disk 12 tops are installed with on the pulley bracket 11 that is bearing in column 9 tops; One end of suspension rod 10 is hinged on rotating disk 12, its other end be can be up and down free end rotationally;

Be installed in the steel rope 6 of the winch 13 on the hull 1, guiding fixed pulley 14, the fixed pulley 8 at pulley bracket 11 tops, suspension rod 10 free-ended fixed pulleys 5.2 by column 9 bottoms, walk around the movable pulley 5 on the suspension hook 4 downwards, upwards walk around second fixed pulley 8.1 at suspension rod 10 free-ended second fixed pulley 5.1, pulley bracket 11 tops again, end is fixed in the free end of suspension rod 10, thereby play the effect that deceleration and suspension rod 10 luffings, suspension hook 4 hoist and land, make guard boat 3 stable rising and falling.

During use, rotate rotating disk 12, make the guard boat 3 on the thwart 2 on the suspension hook 4 subtend hulls 1, start winch 13 and decontrol steel rope 6, suspension hook 4 falls to catching on the lifting rope of guard boat 3; Promoting suspension hook 4 makes guard boat 3 leave thwart 2; Rotate rotating disk 12, make the water surface outside the guard boat 3 subtend hulls 1, loosen steel rope 6 free end of suspension rod 10 is slowly fallen, guard boat 3 can steadily be put on the water surface.

In order when guard boat 3 is put into the water surface, to control position, suspension rod 10 free-ended whereabouts, between permanent seat 10.1 on suspension rod 10 free ends and the rope seat 7 on the pulley bracket 11, connect the location with pulling rope 15 is arranged.

Claims

1, a kind of patrol small lifting appliance comprises installation winch aboard ship, it is characterized in that: be fixed with column on hull, be with the rotating disk that can rotate around it on the column, an end of suspension rod is hinged on rotating disk; Installation winch steel rope is aboard ship walked around the movable pulley on rotating disk top and free-ended fixed pulley of suspension rod and the suspension rod free end bottom suspension hook, and the free end of suspension rod is fixed in the termination.
