The course of work of the embodiment of the present invention is briefly described with reference to the accompanying drawing.
To first direction rotation hand wheel 16, screw rod 4 is also rotated to first direction under the drive of handwheel 16, screw rod 4 and spiral shell
Threaded connection between mother 12 moves screw rod 4 axially upward, and the second limiting section 9 on screw rod 4 passes through lower thrust-bearing 19
Push the spring bottom base 7, spring bottom base 7 drives cylinder 1 to move axially upward by bolt 15, when cylinder 1 moves upwards
After certain distance, the clutch claw 20 of 1 one end of cylinder is separated with cable holder, and live spindle 3 only drives warping end to rotate when rotating,
Cable holder is not driven to rotate.
At this point, warping end spooled cable, sliding axially for hawser can apply an axial thrust load to cylinder 1, when this axial direction
When component is upward, which is transferred to spring 5 by cylinder 1, bolt 15, spring bottom base 7, since spring 5 is in pressure
Contracting state, and 6 position of spring top base remains unchanged, spring 5 is transferred to a tensile force reversed with axial thrust load is generated
Cylinder 1 plays the role of being tensioned cylinder 1, so that the not upward vibration of cylinder 1；When the axial thrust load is downward, axial thrust load transmitting
To the second limiting section 9, since 9 holding position of the second limiting section is constant, it will a power reversed with axial thrust load is generated, so that
The not downward vibration of cylinder 1.
To second direction (opposite with first direction) rotation hand wheel 6, screw rod 4 is under the drive of handwheel 16 also to second direction
Rotation, the threaded connection between screw rod 4 and nut 12 move axially downwards screw rod 4, and the first limiting section 8 on screw rod 4 is logical
18 push the spring top base 6 of up-thrust bearing is crossed, spring top base 6 passes through 5 push the spring bottom base 7 of spring, spring bottom base 7
Cylinder 1 is pushed to move axially downwards, after cylinder 1 moves downward certain distance, the clutch claw 20 and anchor chain of 1 one end of cylinder
Wheel engagement when live spindle 3 rotates, drives cable holder rotation.
At this point, warping end spooled cable, sliding axially for hawser can apply an axial thrust load to cylinder 1, when this axial direction
When component is upward, which is transferred to spring 5 by cylinder 1, bolt 15, spring bottom base 7, since spring 5 is in pressure
Contracting state, and 6 position of spring top base remains unchanged, spring 5 is transferred to a tensile force reversed with axial thrust load is generated
Cylinder 1 plays the role of being tensioned cylinder 1 and cable holder, so that the not upward vibration of cylinder 1 and cable holder；When the axial thrust load to
When lower, axial thrust load is transferred to the second limiting section 9, since 9 holding position of the second limiting section is constant, it will generates one and axial direction
The reversed power of component, so that the not downward vibration of cylinder 1.
The embodiment of the present invention drives cylinder to move up and down by handwheel rotary screw, when screw rod moves upwards, is located at screw rod
On lower thrust-bearing push the spring bottom base, drive cylinder move upwards, realize cylinder and peripheral equipment separation.Screw rod to
When lower movement, the up-thrust bearing push the spring top base on screw rod is moved downward, thus base under holddown spring and spring
Seat drives cylinder to move downward, and realizes the engagement of clutch claw and peripheral equipment on cylinder.Meanwhile in spooled cable, pass through
The reaction force that spring and the second limiting section generate overcomes the vibration up and down of cylinder, to be tensioned cylinder and peripheral equipment.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
