Fig. 4 shows the structural schematic diagram of lifting device configuration tension sensor of the present invention.Fig. 5 A shows that the present invention affects rope
Tension state be tensioning state when tension sensor action schematic diagram.Fig. 5 B shows that the tension state of the invention for affecting rope is
The action schematic diagram of tension sensor when relaxed state.Cooperation is refering to Fig. 4, Fig. 5 A and Fig. 5 B, in one embodiment, lifting dress
Setting 1 may include a tension sensor 50, which is electrically connected the clutch driving unit 12, and the tension sensor 50
To sense the tension state for affecting rope 30, the tension state includes tensioning state and relaxed state.Such as Fig. 4 and Fig. 5 A institute
Show, when it is tensioning state that the tension sensor 50, which measures the tension state for affecting rope 30, the clutch driving unit 12 connection
The fixed pulley 11 so that the fixed pulley 11 enter the controlled rotation mode, and then can control the lifting carrier 40 to be risen, under
Drop stops the operations such as lifting.As shown in figs. 4 and 5b, which measures the tension state for affecting rope 30 as pine
When relaxation state, which is detached from the fixed pulley 11, so that mode is freely rotated into this in the fixed pulley 11, at this time
The fixed pulley 11 can be rotated synchronously with the floating of the lifting carrier 40, and the lifting counterweight 20 can provide an acting in opposition
Power holds the lifting carrier 40, and can prevent this from rope 30 being affected to loosen from the fixed pulley 11.
Referring again to Fig. 4, Fig. 5 A and Fig. 5 B, in one embodiment, the tension sensor 50 include a mechanical detecting part 51 and
One light sensing part 52.This affects rope 30 for the machinery detecting part 51 contact, which detects the position of the machinery detecting part 51
Variation is moved, to judge that this affects the tension state of rope 30.
The machinery detecting part 51 includes a connecting support 511, a mobile bar 512, an idler wheel part 513 and a spring 514.The shifting
Lever 512 runs through the connecting support 511.The idler wheel part 513 connects one end of the mobile bar 512, and the idler wheel part 513 contacts this and leads
Dynamic search 30.The spring 514 is sheathed on the mobile bar 512, and the both ends of the spring 514 abut the connecting support 511 and the rolling respectively
Gear member 513.
The light sensing part 52 detects the change in displacement of the mobile bar 512, to judge that this affects the tension state of rope 30.
In one embodiment, which can be pressure sensor, and the pressure sensor contacts this and affects rope
30, to sense the tension state for affecting rope 30.
Refering to Fig. 6 A to Fig. 6 F, show that lifting device of the present invention is applied to each action schematic diagram attended on board respectively.Such as figure
Shown in 6A, which can be installed on a steamer 2.Cooperation is intended to attend on board refering to Fig. 5 A and Fig. 6 B when crewman P takes canoe B
When, the fixed pulley 11 of the rotating member 10 enters the controlled rotation mode, and measured this of the tension sensor 50 affects rope at this time
30 tension state is tensioning state, and the clutch driving unit 12 links the fixed pulley 11, and drives 11 up time of fixed pulley
Needle rotation, so that the lifting carrier 40 declines.
Cooperation is refering to Fig. 5 B and Fig. 6 C, when the lifting carrier 40 drops to the water surface, because water surface surface tension effects are in this
Carrier 40 is gone up and down, the decrease speed one of the lifting carrier 40 can be made slow, measured this of the tension sensor 50 affects rope at this time
30 tension state can be changed to relaxed state moment, and then the actuation clutch driving unit 12 is detached from the fixed pulley 11, so that
Mode is freely rotated into this in the fixed pulley 11, in this mode, the fixed pulley 11 can with the floating of the lifting carrier 40 and
It rotates synchronously, and opposition provided by the lifting counterweight 20 can hold the lifting carrier 40 and prevent this from affecting rope 30
It is loosened from the fixed pulley 11.In addition, canoe B can (figure not be drawn using a connection piece after the lifting carrier 40 drops to the water surface
Out) together with the lifting carrier 40 connection, so that canoe B can be synchronous with water surface floating with the lifting carrier 40.
As shown in Figure 6 D, when canoe B is jacked up upwards by water flow W, which can be upward together with canoe B
It is mobile, so that the distance between the lifting carrier 40 and canoe B not will receive the fluctuating of water flow W and change, and then ensure ship
Member P can climb up safely the lifting carrier 40.
As illustrated in fig. 6e, after crewman P climbs up the lifting carrier 40, canoe B can be detached from the lifting carrier 40, and should
Fixed pulley 11 is again introduced into the controlled rotation mode, and the clutch driving unit 12 can drive the fixed pulley 11 to turn counterclockwise at this time
It is dynamic, so that the lifting carrier 40 rises.As fig 6 f illustrates, after the lifting carrier 40 rises to appropriate location, crewman P can be suitable
Benefit is attended on board.
As described above, lifting device 1 of the invention, which controls this using the clutch driving unit 12 of the rotating member 10, determines cunning
The different rotation modes of wheel 11, and match the lifting of the lifting carrier 40 by the lifting counterweight 20 and regulate and control this and affect rope 30
Tension state, can make the lifting carrier 40 and canoe B synchronize float up and down, to ensure the lifting carrier 40 and canoe B
The distance between not will receive the fluctuating of water flow W and change, and then improve the safety attended on board of crewman.In addition, liter of the invention
Falling unit 1 is equally applicable for other operation at sea utensils other than it can be applied to attend on board.
Above-described embodiment is only to illustrate the principle of the present invention and its effect, the not limitation present invention, therefore art technology
