Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment:

Further describe embodiment in conjunction with the accompanying drawings, the utility model is to be support with the serial helicopter fuselage 12 of rice-17, at its 7#, 10# strengthens on outside mooring point of cabinet and the armrack hanging point and the fuselage appearance special-shaped corbel 9 of configuration that fits, there is a bench board 7 at the middle part of corbel with support pull bar 4 horizontal fixed, two supporting legs 8 are arranged to floor mounted below the outside of bench board, be vertically installed with a principal post 3 on the bench board mediad, principal post is to be formed by five joint butt joints, three joints are formed open-air mated condition in the middle of when dispatching from the factory, do not need dismounting generally speaking, the higher authorities' a joint is fixed a criss-cross arm 2, following a joint is connected with middle three joint counterparts, arm one end stretches out to the horizontal 95-100 of fuselage direction °, two ends are respectively equipped with a fixed pulley 1 on arm, on column, be higher than bench board one descending operation platform 10 is installed laterally, the descending operation platform is provided with bottle gouard moved by hands 6, the cable wire of bottle gouard moved by hands upwards through outside fixed pulley and inboard fixed pulley to the following handling connecting element 11 that is connected with, in column top and arm, be connected with support pull bar 4 with multi-functional lug respectively between the outside, in arm inboard and bench board inboard and principal post, be respectively equipped with the support pull bar between the joint, between descending operation platform and the bench board and the arm outside, also be connected with the support pull bar respectively.In order to lift the parts of Different Weight, on arm, be respectively equipped with A, B, four suspension centres of C, D apart from fuselage line of centers corresponding position.

The package program of this device is as follows: (1) assembling table: the special-shaped corbel that will have lug earlier is installed on the fuselage of helicopter, and the midway location of lug before and after hoist attachment is placed on, bench board is lifted, the following joint of column is inserted in the centre hole, insert in the hole of saving down after middle joint column being loaded onto bottle gouard moved by hands, with hanging belt holder post two ends, spur bottle gouard moved by hands again and slowly bench board is sling.When exceeding 10 centimeters of fuselage fuel cell vertexs below the bench board, stop to hoist, with it to the slow translation of fuselage, until fuselage lug point of connection position, slowly move again, until the mounting hole of aiming at fuselage lug point, be respectively charged into bolt of rear end plate and fastening again, prop up firm flat-bed outer ledge with supporting leg, fall the bottle gouard moved by hands suspension hook, bench board is fallen naturally, (2) arm and column to dress, it is also fastening good earlier arm assembly and the following joint column that connects to be linked to each other with middle joint column, and is placed in the ground of fuselage side by installation direction, again with hoist attachment device distance that goes up the joint column of translation outside fuselage, and the center guarantees and the table axis basically identical, hangs the two ends that the joint column is gone up in the jail with suspender belt again, spurs bottle gouard moved by hands again and slowly it is sling, when near bench board to joint chair the time stop to hoist, behind the flange mounting hole of aligning to joint chair, distinguish bolt of rear end plate again, fall suspension hook and remove suspender belt.(3) column, arm docks with bench board, earlier with about 3 meters of hoist attachment translation outside fuselage, and the center guarantees and the table axis basically identical, again the center of gravity of arm and columns assemblies is placed the center of hoist attachment, following joint column is inserted in the bench board centre hole, after installing two bottle gouards moved by hands on the middle joint column, insert in the hole of following joint column again, lifting chain with two bottle gouards moved by hands saves column and arm on hoisting point position ties, pulling bottle gouard moved by hands lifting chain is manually guarded the center-of-gravity position displacement, and slowly it is sling, when near bench board to joint chair the time, stop to hoist, aim at flange mounting hole, be respectively charged into bolt of rear end plate and fastening joint chair; Pinion the main gear reducer output shaft of arm and column bonded assembly cross joint and helicopter respectively with two hanging belts, two suspender belts have been connected and fixed respectively with bottle gouard moved by hands, pulling hoists and leads chain, tighten up suspender belt and remove the lifting chain that is fixed on hoisting point position, slowly pull-up arm and last joint column, when the joint column is pulled up to the upright position in the range estimation, stop pull-up, below bench board both sides lug place with above the support pull bar fastening, again any support pull bar in the outside, both sides is adjusted to the size that is connected with arm, multi-functional lug is pushed in the arm lug, penetrate bolt and fastening, continue the size that pulling is gone up the joint column and regulated the support pull bar, adjust other all support pull bars and fixing of packing into successively.From bench board bottom root is supportted the pull bar connecting element again and pushes column, penetrate bolt and fastening, and by the squareness adjustment of the levelness of bench board or column, lock all and support pull bar up and down, put down then, remove hanging belt.

During the lifting weight, at first should carry out unloaded trail run, check that the positive back whole process of jigger is no abnormal, the rotary suspension arm anglec of rotation is greater than 120 °, each turning unit should rotate flexibly, carry out weight again after the no catching phenomenon lifts by crane.During the weight lifting, should lift by crane the weight of regulation at the suspension centre of each regulation, after the weight lifting, should observe the whole state of suspender on helicopter, overweight phenomenon can not be arranged, below object, answer hauling rope of pre-hung along the drop point direction, under the traction of hauling rope pulling force, a/s rotative speed slowly rotates the handle of speed reduction gearing, and hanging object is slowly rotated along the regulation hand of rotation, after going to drop point, stop the rotation, slowly weight unloaded.Behind the rigging out, remove by the anti-order of stack-mounted.
