A. 4 and bracing frame 1; Stock 2 is sleeved on the two sliding block joint of outside of standard knot 3; First pulley 13, second pulley 14, the 3rd pulley 15 all are contained in the top of stock 2; Second pulley 14 is between first pulley 13 and the 3rd pulley 15, and boatswain chair 12 is contained in the bottom in the standard knot 3, is fixed with the 4th pulley 16, the 5th pulley 17 and two permanent seats 24 on the boatswain chair 12; The 6th pulley 18, the 7th pulley 19, the 8th pulley 20 and the 9th pulley 21 coaxial stock 2 bottoms that are packed in; Fast suspension bracket is established motor 5, fixedly otic placode 6, first connects otic placode 7, second and connects otic placode 8, the 9th pulley 21 and the tenth pulley 22 and be packed on the bracing frame, and the suspension bracket mouth of establishing motor 5 is connected with an end of first steel rope 9 soon, and the other end of first steel rope 9 is after pile warp is crossed the tenth pulley the 22, the 11 pulley 23 and the 6th pulley 18 successively; Upwards pile warp first pulley 13 backs get into boatswain chair 12 downwards; Upwards return behind pile warp the 4th pulley 16, the 14 back switching-overs of pile warp second pulley are downward, through upwards returning behind the 5th pulley 17; The 15 back switching-overs of pile warp the 3rd pulley downwards; Be connected with fixing otic placode 6 through the 9th pulley 21 back, the first connection otic placode 7 is connected with an end of second steel rope 10, and other end pile warp the 8th pulley 20 of second steel rope 10 is connected with corresponding permanent seat 24; Second connects otic placode 8 is connected with an end of the 3rd steel rope 11, and other end pile warp the 7th pulley 19 of the 3rd steel rope 11 is connected with corresponding permanent seat 24.

The specific embodiment two: combine Fig. 3 that this embodiment is described, second pulley 14 of this embodiment and the 13 vertical settings of first pulley, first pulley 13 and the 3rd pulley 15 laterally arrange.Other composition and annexation are identical with the specific embodiment one.

The specific embodiment three: combine Fig. 1 that this embodiment is described, the combination mechanism of this embodiment also comprises rotary support 25 and axis of revolution 26, and rotary support 25 is connected with bracing frame 1 through axis of revolution 26.Other composition and annexation are identical with the specific embodiment one.

The specific embodiment four: combine Fig. 1 that this embodiment is described, the combination mechanism of this embodiment also comprise have a spring auto-lock function climb pawl 27, climb the top that pawl 27 is packed in stock 2.In the process that standard knot 3 rises,, climb pawl 27 and just can collude the horizontal steelframe of catching on the standard knot 3 whenever arriving certain altitude.This structure makes standard knot 3 after rise, can't fall voluntarily, thereby has guaranteed the safe reliability that the tower frame is established.Other composition and annexation are identical with the specific embodiment one.

Principle of work: folding, the upright and work of hoisting of body of the tower (stock 2 and standard knot 3) is to rely on fast suspension bracket to establish motor 5 to accomplish.When body of the tower folded accumbency, the triangle end of stock 2 leant out rotary support 25 under the effect of S. A. 4, and standard knot 3 is near stock 2 bottoms.Connect otic placode 7 from first and be connected otic placode 8 with second via the 6th pulley 18 and the 9th pulley 21, second steel rope 10 and the 3rd steel rope 13 that finally are fixed in two permanent seats 24 are in tensioned state.At this moment; Use fast suspension bracket to establish motor 5 and carry out the take-up operation; Then first steel rope 9 can be moved to the left by traction standard knot 3 interior boatswain chairs 12; Under second steel rope 10 before and 11 effects of the 3rd steel rope, the triangle shaped tip of stock 2 can be taken in rotary support 25, and body of the tower slowly erects simultaneously.After treating that body of the tower is upright, insert set pin 28, stock 2 and S. A. 4 are pinned, body of the tower is kept upright, break off second steel rope 10 and the 3rd steel rope 11 then, standard knot 3 is risen from stock 2.

Along with fast suspension bracket is established motor 5 soon and further carried out take-up action, first steel rope 9 drives standard knot 3 and rises overally through first pulley 13, second pulley 14 and the 3rd pulley 15 traction boatswain chairs 12.The mobile up-down of standard knot 3 is to rely on fast suspension bracket to establish motor 5 to accomplish through the traction of 9 pairs of boatswain chairs 12 of first steel rope.

When the tower machine need be operated opposite with said process when mode of operation returns to folded state.The fast suspension bracket of tower machine is established motor 5 and is worked in the unwrapping wire state, before standard knot 3 is packed up, at first will draw back and climb pawl 27, makes between stock 2 and the standard knot 3 to be separated.The effect of establishing motor 5 unwrapping wire and standard knot 3 self gravitations through too fast suspension bracket, but the inside of standard knot 3 at high speed retraction stocks 2.When standard knot 3 during near the bottom part of stock 2, connect second steel rope 10 and the 3rd steel rope 11 again this moment, extracts set pin 28; Then under motor 5 unwrapping wire effects; Rotary support 25 tilts to drop to the ground, and in this stage, stock 2 begins to tilt to drop to the ground to rotary support 25.Finally, fast suspension bracket is established motor 5 unwrapping wire and is finished, and body of the tower is lying on the rotary support 25, and the 7th pulley 19 and the 8th pulley 20 lean out, and standard knot 3 arrives at the bottom of stock 2, and whole tower machine folding movement is accomplished.
