The axial rotation of kelly 29.
When practical operation of the present invention, the pulley 14 on holder 13 can drive Mobile base 2 to be moved, when being moved to needs
It behind position, needs to fix Mobile base 2 on the spot, when fixed, rotary worm 8, worm screw 8 engages with worm gear 10,10 band of worm gear
Dynamic first threaded rod 9 rotation, since the first nut 11 is connect by first connecting rod 12 with the second column 6, the second column 6 and with the
One sliding block 5 connects, and the first sliding block 5 can only slide in the first sliding groove 4, therefore be restricted can be for the first nut 11
It is moved on one threaded rod 9, the first threaded rod 9 drives the second column 6 to be moved down in the first column 3, the second column 6 from first
It is stretched in column 3, the upper surface of the second column 6 and bridge 1 contact and support Mobile base 2, at this moment play a supporting role
Be the second column 6, pulley 14 is not contacted with bridge 1, to have the function that Mobile base 2 is fixed, to bridge 1 into
When row repair, worker station repairs the both sides of bridge 1 in hanging basket 18, since the thickness of bridge 1 is larger, in order to facilitate work
People can comprehensively repair bridge 1, it is therefore desirable to hanging basket 18 can up and down adjustment, when adjusting, rotate the first bull stick 20, first
Bull stick 20 is rotated with moving gear 21, and gear 21 is engaged with rack 22, and rack 22 drives the second telescopic rod 17 in the first telescopic rod 16
In move up and down, after regulating the position of hanging basket 18, by the effect of gravity free-falling is occurred for hanging basket 18 in order to prevent, because
This will be fixed the first bull stick 20 to prevent gear 21 from being engaged with rack 22, when fixed, the second bull stick 23 of rotation, and second turn
Bar 23 drives the rotation of the first helical gear 24, the first helical gear 24 to be engaged with the second helical gear 27, and the second helical gear 27 drives second
Threaded rod 26 rotates, and since the second nut 28 is connect by second connecting rod 39 with third sliding block 38, and third sliding block 38 can only be
It is slided in third sliding slot 37, therefore the second nut 28 can move on the second threaded rod 26, the second nut 28 is with the first card
Bar 29 and the first card slot 30 are clamped, and at this moment the first bull stick 20 is fixed on sleeve 19, and gear 21 stops move opposite with rack 22
Dynamic, to which position of second telescopic rod 17 in the first telescopic rod 16 is fixed, worker can carry out activity.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
