The coefficient of friction of cooperation is low more than steel sheave, therefore it is not needed plus lubricating oil, solves pulley problem of rustiness, reduces client
To the cost of product maintenance maintenance.
Detailed description of the invention
Fig. 1 is a kind of side structure schematic diagram of the novel keel block of embodiment of the utility model；
Fig. 2 is a kind of positive structure schematic of the novel keel block of embodiment of the utility model.
Specific embodiment
1 and 2 pair of the utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of novel keel block, including
Pedestal 1, lower end are equipped with winch 2, and winch 2 is a kind of reel winding wire ropes or chain lifting or traction
Light and small heavy-duty hoisting equipment, also known as elevator, winch 2 is by the control rotation of boom 3 to make lifeboat liter in the novel keel block
It falls.1 upper end of machine base is hinged with the boom 3 by 15 connection winch 2 of steel cable, and pedestal 1 and 3 junction of boom are additionally provided with for solid
Determine the angle pulley 4 of steel cable 15.
Boom 3, tail end and pedestal 1 are hinged, 3 front end of boom be additionally provided with driving pulley 5 and with fixed lifeboat
Ship loop chain 6 is fished, winch 2 can control boom 3 by angle pulley 4, driving pulley 5 and steel cable 15 and rotate, and 6 lower end of ship loop chain is fished to set
There is suspension hook 7.
As shown in Fig. 2, control-rod 8, is fixedly connected with 3 front end of boom, 8 one end of control-rod, which is connected with, can protrude into lifeboat
Interior control steel cable 159, control steel cable 159 and the switch of winch 2 connect, therefore control steel cable 159 and can control the operating of winch 2.
Therefore by the control-rod 8, operator's liter of i.e. controllable lifeboat in lifeboat is fallen.
In the present embodiment, driving pulley 5 is made of PA66 nylon material.PA66 nylon material has wear-resisting, anti-corrosion
The features such as performance is strong.It is low more than steel sheave with the coefficient of friction of steel bearings cooperation, therefore it is not needed plus lubricating oil, subtracts
Lack the material of fuel filler neck, this part of copper oil pipe.Also client's long-time service is greatly facilitated.
In the present embodiment, 3 front end of boom is equipped with the fixation through hole for fixing pulley spindle, and driving pulley 5 passes through cunning
Wheel is located in 3 two sides of boom.3 two sides of boom are provided with symmetrical driving pulley 5, make 3 uniform force of boom, connect more steady
Gu.
In the present embodiment, pedestal 1 is additionally provided with mobilizable fixed arm 10, and fixed arm 10 is provided with boom 3 and is used for
The fixed hook 11 of fixed lifeboat, when boom 3 slings lifeboat can by fixed hook 11 and steel cable 15 to lifeboat into
Row is fixed.Since sea generally has larger sea wind, lifeboat is easy rocking by breeze during hanging and falling, and
By steel cable 15 around the fixed hook 11 and lifeboat on fixed arm 10 and boom 3, but lifeboat is during being hung
It keeps stablizing.
In the present embodiment, it is additionally provided with the first Universal pulley 12 between boom 3 and fishing ship loop chain 6, ship loop chain 6 is fished to pass through
Universal pulley is flexibly connected with boom 3.First Universal pulley 12 can make that ship loop chain 6 is fished arbitrarily to rotate, and facilitate the selection of suspension hook 7 suitable
Angle to lifeboat lift by crane.
In the present embodiment, 8 lower end of control-rod is provided with the second Universal pulley 13, and control steel cable 159 is universal by second
Pulley 13 connects control-rod 8, and the second Universal pulley 13 can arbitrarily be rotated with control steel cable 159, prevents control steel cable 159 from using
It knots in the process, and then influences operation.
In the present embodiment, control 159 lower end of steel cable is equipped with for making the pouring weight 14 of the holding of steel cable 15 straight down.It is sitting in
Operator in lifeboat can operate winch 2 for lifeboat into the water by control steel cable 159, since sea generally has
Larger sea wind causes control steel cable 159 to be easy to be blown partially, and operator is not easy to obtain control steel cable 159, therefore is controlling steel cable
159 lower ends, which are tied with pouring weight 14, can make steel cable 15 keep vertically downward direction.
Above-described is only some embodiments of the utility model, for those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
