It is enough to fix support plate.When to make that sheet reset is supported to unclamp walling crib, manually unclamp fixed mechanism by guide rod, first
Supporting plate can be made to move up reset under the elastic force effect of spring, so as to unclamp two support sheet resets by walling crib.
When guide rod to be made moves down, manual rotation's turntable rotates first rotating shaft, and torsional spring distorts therewith, and first turn
Axis rotation drives convex block rotation, contacts the vertical plane of convex block with universal wheel, can then move down guide rod, is oriented to
Bar move down drive guide rod on all components move down, such universal wheel moves down therewith, when universal wheel to
Under when being moved to the downside of convex block, unclamp turntable, reset first rotating shaft rotation under the action of torsional spring, first rotating shaft rotation is multiple
Position convex block resets therewith, and universal wheel is blocked fixation by such convex block, and strut and idler wheel can prevent oscillating rod to lower swing, so
Guide rod can be fixed, prevent guide rod from moving up.When guide rod to be made moves up reset, repeating aforesaid operations is
It can.
Directive wheel play the guiding role, and wirerope can be made more smoothly to move up and down, and prevents wirerope double swerve, bullet
Spring plate is worked as a buffer with elasticity.
Beneficial effect is: the support member of supporting mechanism of the present invention can support walling crib, and fixed mechanism can will prop up
The support member of support mechanism, which is blocked, prevents walling crib from falling, and so that reel is released wirerope, walling crib can be so put into well, nothing
Need manually walling crib is put into well, so as to improve walling crib place efficiency, can reduce labor intensity, by countersunk nut from
It screws out, the present invention can so be split, so as to be moved easily the present invention in card slot.

When needing for walling crib to be put into well, the present invention is placed at well mouth, the present invention is made to be located at well mouth
Surface, and walling crib is made to be located at the lower section that the present invention places.When initial, supporting mechanism 11 is located at eminence, and manually starting motor 8 makes
Reel 9, which rotates counterclockwise, releases wirerope 10, and supporting mechanism 11 moves down therewith, when supporting mechanism 11 is moved downward to well
When the downside of circle, motor 8 is closed.Unclamp fixed mechanism 12 by the support member of supporting mechanism 11, then people again
Work supports the support member of supporting mechanism 11 by walling crib, then makes support member card of the fixed mechanism 12 by supporting mechanism 11
Firmly, then restarting motor 8 makes reel 9 release wirerope 10, so walling crib can be put into well, when walling crib is put into water
After suitable position in well, motor 8 is closed.It unclamps fixed mechanism 12 by the support member of supporting mechanism 11, then makes to prop up
The support member of support mechanism 11 unclamps walling crib, and subsequent start-up motor 8 makes reel 9 rotate clockwise withdrawal wirerope 10, such as
This makes supporting mechanism 11 move up reset, after supporting mechanism 11 moves up reset, closes motor 8.So it is not necessarily to
Manually walling crib is put into well, efficiency is placed so as to improve walling crib, can reduce labor intensity.Repeating aforesaid operations will
Walling crib is put into well one by one, after the completion of the whole placements of walling crib, countersunk nut 4 can be screwed out out of card slot 6, can so be incited somebody to action
The present invention is split, and so as to be moved easily the present invention, when needing to reuse the present invention, countersunk nut 4 is screwed in and is blocked
The present invention can be combined in slot 6.
Manually unclamp fixed mechanism 12 by guide rod 114, pressing pressing plate 115 still further below moves down guide rod 114,
Guide rod 114, which moves down, drives supporting plate 116 to move down, and the first spring 117 is upheld therewith, and supporting plate 116 moves downwards through
First connecting rod 118 and slide bar 1110 can be such that support plate 1111 is displaced outwardly, and support walling crib when support plate 1111 is displaced outwardly
When firmly, manually make fixed mechanism 12 that guide rod 114 is fixed, it so can be fixed by support plate 1111.When support plate to be made
It when walling crib is unclamped in 1111 resets, unclamps fixed mechanism 12 by guide rod 114, is acted in the elastic force of the first spring 117
Under supporting plate 116 can be made to move up reset, walling crib is unclamped so as to reset two support plates 1111.
When guide rod 114 to be made moves down, manual rotation's turntable 123 make first rotating shaft 122 rotate, torsional spring 125 with
Distortion, first rotating shaft 122 rotation drive convex block 124 rotate, contact the vertical plane of convex block 124 with universal wheel 129, with
After can move down guide rod 114, guide rod 114, which moves down, drives all components on guide rod 114 to move down,
Such universal wheel 129 moves down therewith, when universal wheel 129 is moved downward to the downside of convex block 124, unclamps turntable 123, In
Reset the rotation of first rotating shaft 122 under the action of torsional spring 125, the rotation of first rotating shaft 122 resets convex block 124 and resets therewith, so
Universal wheel 129 is blocked fixation by convex block 124, and strut 1211 and idler wheel 1212 can prevent oscillating rod 127 to lower swing, such energy
