The bonding strength of strong fixed board 11 and screw shell 12；Bolt is fixedly connected with 19 end of movable plate respectively at 11 both ends of fixed plate
Portion, 19 the other end of movable plate are slidably connected sliding slot 20, and 20 fixed connection apparatus body 1 of sliding slot, movable plate 19 can be along sliding slots
20 move up and down without rotatable；The 12 internal whorl connection wire rod 13 of screw shell, 13 top of screw is fixedly connected with first
Bevel gear 14,13 top axle of screw hold 1 upper wall of rotary connecting device body, 14 right end of first bevel gear engagement connection the second cone tooth
Wheel 15, and second bevel gear 15 is fixedly connected with 16 left end of shaft；Firm 17 lower end of bar of 16 left part of shaft rotation connection, consolidates
17 upper end fixed connection apparatus body of bar, 1 upper wall, 16 right end of shaft are fixedly connected with runner 18, and rotating wheel 18 drives 16 turns of shaft
Dynamic and then driving second bevel gear 15 and first bevel gear 14 rotate the height for adjusting screw shell 12 and then drive worm gear 3 and drive
Dynamic worm screw 2 separates.
5 surface scrolls of take-up reel connect flexible steel wire 25, and 25 lower end of flexible steel wire, which is worn, connects friction pulley 27, friction pulley 27
Lower end is rotatablely connected fixing bracket 26, and 26 lower end fixed connection apparatus body 1 of fixing bracket, when flexible steel wire 25 upwards or to
Reduce the friction of flexible steel wire 25 and device body 1 during lower movement by friction pulley 27, avoid damage flexible steel wire 25；The dress
Put 1 lower end of body and be fixedly connected with leg 10, leg 10 is used for holding meanss body 1 to be prevented from skidding with ground good contact.
1 right end sidewalls of described device body are fixedly connected with fixed catheter 21,21 interpolation connecting sleeve lever 28 of fixed catheter, loop bar 28
It can be moved left and right in fixed catheter 21；28 left end of loop bar is hinged shift fork 22, and 22 lower end of shift fork sets limited block 29, and limits
Position block 29 is fixedly connected with loop bar 28, and limited block 29 is so that shift fork 22 rotates counterclockwise maximum to horizontal level, when worm gear 3 and driving
When worm screw 2 engages, shift fork 22 is separated with ratchet 4, causes shift fork 22 and 4 knot of ratchet when screw shell 12 drives worm gear 3 to move up
Close, prevent cargo from falling the locking of ratchet 4 by shift fork 22.
2 upper end of the driving worm screw rolls connection transmission belt 8, and 8 upper end of transmission belt rolls connection driven shaft 7, and driven shaft 7
Left end is fixedly connected with fan 9, and driving worm screw 2 rotates follows rotation and then 9 turns of driving fan by the drive driven shaft 7 of transmission belt 8
Dynamic blowing cools down for construction worker's relieving summer-heat.
The operation principle of the utility model is：The 23 energization work of driving motor drives driving worm screw 2 to rotate and then drive snail
Wheel 3 follows rotations, and since worm gear 3 is fixedly connected with ratchet 4, ratchet 4 is fixedly connected with take-up reel 5, therefore worm gear 3 and ratchet 4 and receipts
Drum 5 becomes an entirety, and three is synchronous when moving up and down or rotating, and worm gear 3 drives take-up reel 5 to rotate tightening wire hawser
Rope 25 and then by the heavy lift of 25 lower end of flexible steel wire, since Worm Wheel System has self-locking effect, i.e., only by driving
Worm screw 2 drives worm gear 3 to rotate, and when driving motor 23 to break down or emergency case has a power failure, worm gear 3 cannot drive driving
Worm screw 2 inverts, and ensures that the weight of 25 lower end of flexible steel wire will not fall and causes casualty situations, when weight is promoted to desired height
After carry out off-load, rotating wheel 18 after off-load, runner 18 drive shaft 16 rotate so that drive second bevel gear 15 and first cone
Gear 14 rotates, and the first bevel gear 14 of rotation drives the screw 13 of connection fixed thereto to rotate synchronously, since screw 13 can only
Rotate and cannot move up and down, and screw shell 12 can only be moved up and down under the action of movable plate 19 and cannot rotated, therefore work as
Screw 13 moves up and down when rotating with the screw shell 12 that it is threadedly coupled, and screw 13 drives screw shell 12 to move up, thread bush
Cylinder 12 drives the worm gear 3 of lower end rotation connection, and ratchet 4, take-up reel 5 are overall to move up, and worm gear 3 is with driving during movement
Dynamic worm screw 2 separates, and shift fork 22 interacts with ratchet 4 and pins ratchet 4 again while separation, and operating personnel buttress at this time
Handle 6, twitches loop bar 28 and drives shift fork 22 to be separated with ratchet 4, slowly rotate the loading that handle 6 fixes 25 lower end of flexible steel wire
Thing is put down carries heavy lift again.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of the spirit or essential attributes without departing substantially from the utility model, it can realize that this practicality is new in other specific forms
