The technical solution of the utility model is:
A kind of hoisting and overturning device of heavy towers section, comprise the upper hanger lifting and the lifting of lower hanger that are separated and arrange, described upper hanger lifting comprises two hoisting and overturning mechanisms be symmetrical set, described hoisting and overturning mechanism comprise connect successively up and down lifting supporting mechanism, stand up auxiliary mechanism and stressed gripping body; Described auxiliary mechanism of standing up comprises single block, is arranged with steel rope in the pulley groove of described single block; Described lifting supporting mechanism comprises annular suspender belt, and described annular suspender belt is connected to the suspension ring of single block by the female shackle of corresponding first arcus; Described stressed gripping body comprises two upper hangers setting up and down, and described upper hanger is connected to the two ends of described steel rope respectively by the female shackle of corresponding second arcus; Described lower hanger lifting comprises about two the support gripping bodies arranged, and described support gripping body comprises eyes suspender belt setting up and down and lower hanger, is connected between described eyes suspender belt with lower hanger by the female shackle of corresponding 3rd arcus.
The mounting hole place of described upper hanger and lower hanger is provided with assembling bolt.
The nut that described assembling bolt comprises outer-hexagonal bolt, bullet pad, plain cushion and matches with outer-hexagonal bolt.
Advantage of the present utility model:
By design of the present utility model, in the situation ensureing that in hoisting process, product is injury-free, reduce lifting risk, guarantee carrying out smoothly of hoisting and overturning, the most important thing is to improve production efficiency greatly, saved cost.

Detailed description of the invention
Now embodiment is described in further detail structure of the present utility model by reference to the accompanying drawings for the ease of it will be appreciated by those skilled in the art that:
With reference to Fig. 1-2, a kind of hoisting and overturning device of heavy towers section, comprise the upper hanger lifting and the lifting of lower hanger that are separated and arrange, described upper hanger lifting comprises two hoisting and overturning mechanisms be symmetrical set, described hoisting and overturning mechanism comprise connect successively up and down lifting supporting mechanism, stand up auxiliary mechanism and stressed gripping body; Described standing up in pulley groove that auxiliary mechanism comprises 45T single block Isosorbide-5-Nitrae 5T single block 1 is arranged with Φ 50mm steel rope 2; Described lifting supporting mechanism comprises the long 45T for 2.5m annular suspender belt 3,45T annular suspender belt 3 is connected to 45T single block 1 suspension ring by the female shackle 4 of corresponding 55T first arcus; Described stressed gripping body comprises two upper hangers 5 setting up and down, and described upper hanger 5 is connected to the two ends of Φ 50mm steel rope 2 respectively by the female shackle 8 of corresponding 35T second arcus; Described lower hanger lifting comprises about two the support gripping bodies arranged, described support gripping body comprises category-A eyes suspender belt 6 setting up and down and lower hanger 7, described category-A eyes suspender belt 6 is connected by the female shackle 9 of corresponding 35T the 3rd arcus with between lower hanger 7, and the load-bearing of category-A eyes suspender belt 6 is 30T; The mounting hole place of described upper hanger 5 and lower hanger 7 is provided with the nut (mark) that M42 assembling bolt 10, M42 assembling bolt 10 comprises outer-hexagonal bolt, bullet pad, plain cushion and matches with outer-hexagonal bolt.
Described upper hanger 5 and lower hanger 7 design 3 times of safety factors, improve the safety of hoisting and overturning.
Be separately positioned on the corresponding position of heavy towers section 12 liang of end flanges 11 by upper hanger 5 and lower hanger 7, re-use M42 assembling bolt 10 and upper hanger 5 and lower hanger 7 are connected with the flange 11 at two ends and lock respectively.150T gauntry crane is transported to by 100T flat truck, 45T annular suspender belt 3, the female shackle 4 of 55T first arcus, 45T single block 1, Φ 50mm steel rope 2 and the female shackle 8 of 35T second arcus being connected to together, hanging on 100T main hook as promoting suspension centre (being hanger lifting); Using 30T and length is the female shackle 9 of the category-A eyes suspender belt 6 of 8m and 35T the 3rd arcus link together hang over 50T auxiliary hook on as auxiliary suspension centre (being lower hanger to lift).
Female for four of the suspension centre that hoists 35T second arcuses shackle 8 be connected with corresponding upper hanger 5 respectively during hoisting and overturning, the female shackle 9 of two 35T the 3rd arcus of auxiliary suspension centre is connected with corresponding lower hanger 7 respectively; Operating personal need require operation according to ground commanding, and first adjust hoisting heavy tower section 12, handling, to assigned position, is guaranteed that heavy towers section 12 is apart from more than half meter, ground, and completed lifting and the transport of heavy towers section 12; Suspension centre will be assisted motionless as bench mark, the suspension centre that slowly will hoist raises, and Φ 50mm steel rope 2 can rotate and uniform stressed along with 45T single block 1, and upper hanger 5 is promoted to top and just completes heavy towers section 12 and stand up process, heavy towers section 12 is vertically placed on frock moulding bed, removes lower hanger 7.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
