Specific embodiment
A kind of two-freedom feedback adjustment rope grip mechanism as depicted in figs. 1 and 2, it is characterised in that: including shell 1, shell
It is enclosed structure that the internal symmetry of body 1, which is equipped with two groups of movable back wedges 2, ball row 6 and the main wedge 7 of card rope, shell 1, be can be used
Monoblock type or the mode of seperated splicing.
Ball row 6 is freely placed between movable back wedge 2 and the main wedge 7 of card rope, and card is made to restrict main wedge 7 relative to movable back wedge 2
In vertical direction movement to roll, the two sides of shell 1 are equipped with multiple groups plunger shaft 9, and 9 tail portion of plunger shaft of every side is ganged up, and
There are hull outside interface, each plunger shaft 9 is equipped with force adjustment piston 5, and 2 lateral surface of movable back wedge and the rod end of force adjustment piston 5 are solid
Fixed connection can move in the horizontal direction adjustment with force adjustment piston 5, and 2 top of movable back wedge is groove type structure, and limiter stud 3 is pacified
Mounted in the lower part of groove, force adjustment motor 4 is mounted on groove top, and the lower part of limiter stud 3 is threadedly coupled with movable back wedge 2, limit
The spindle nose of 3 top inner hole of power stud and force adjustment motor 4 cooperates, and 3 top of limiter stud is cylinder, with leading for card main 7 top of wedge of rope
To Kong Peihe.
3 lower part of limiter stud is external screw thread, the screw-internal thread fit with 2 top of movable back wedge, 3 top of limiter stud
For the diameter cylinder small compared with external screw thread, there is interior circular hole at the top of limiter stud 3, there is a guide key groove in hole side, interior circular hole, guide key groove with
The spindle nose of force adjustment motor 4 cooperates, and allows force adjustment motor 4 that limiter stud 3 to be driven to rotate, and limiter stud 3 can be relative to tune
Force motor 4 and movable back wedge 2 move in the vertical direction.
The main wedge 7 of the card rope is wedge structure, and there is the arc groove 10 of cooperation wirerope 8 in inside, has at the top of the main wedge 7 of card rope
The guide plate 11 stretched out outward has the pilot hole cooperated with limiter stud 3 on guide plate 11, and guide hole size is than limiter stud
Upper cylindrical diameter is big, smaller than limiter stud lower external thread diameter, when card restricts main wedge 7 along the up and down motion of limiter stud 3,
Moving downward position will be limited by 3 hierarchic structure of limiter stud, which can be carried out by the up and down motion of limiter stud 3
Control adjustment.
It is living to force adjustment that the inside of the plunger shaft 9 is full of hydraulic medium, the external hydraulic pump of hull outside interface and valve group
Plug 5 is controlled, and under external force, the piston rod of force adjustment piston 5 can be stretched out or be retracted from plunger shaft.
Before use, filling hydraulic medium to 1 plunger shaft 9 of shell, keep the piston rod of force adjustment piston 5 fully extended, it is left at this time
Spacing between right two groups of main wedges of card rope is minimum, is then shut off the external interface of plunger shaft 9.This movement can pass through external hydraulic pump
And valve group is controlled.Then according to the height and position of preset clamping force parameter adjustment limiter stud 3.
When work, the main 7 clamped wire rope 8 of wedge of card rope, and moved downward with wirerope 8.When the main wedge 7 of card rope moves downwardly to
Stop when the stepped locations of limiter stud 3, generates certain chucking power.By external chucking power detecting element, measurement is practical
The chucking power numerical value of generation, and be compared with preset chucking power.When the chucking power of detection, feedback is less than preset value, control
Force adjustment motor 4 processed operates, and force adjustment motor 4 drives limiter stud 3 to move downward, and the main wedge 7 of card rope is allow to continue to move downward, from
And increase chucking power；When the chucking power of detection, feedback is greater than preset value, the external interface of control 1 plunger shaft of shell is opened, row
Section hydraulic medium out, force adjustment piston 5 bounce back, and increase the spacing of two groups of left and right wedge, to reduce chucking power.By above
Mode can in real time feed back the chucking power of rope grip mechanism, be adjusted, to obtain accurate, stable chucking power.The above inspection
It surveys, control process can be realized by external electrical, Hydraulic Elements.
When work, rope grip mechanism maintains certain chucking power, and limiter stud 3 is moved upwards to be stretched out with force adjustment piston 5
Difficulty, so it is not recommended that movement.
