Fig. 2 is the cantilever crane collapsed state schematic diagram of the utility model.

Specific embodiment

As shown in Figure 1, anti-high wind derrick crane pylon described in the utility model, including by being perpendicularly fixed on ground Tower body 1, and be horizontally placed on 1 top of tower body cantilever crane constitute pylon ontology, cantilever crane by linking arm 2, be articulated with connection Crane arm 3 that 2 front end of arm longitudinally rotates is articulated with the counter-jib 4 that 2 rear end of linking arm longitudinally rotates and constitutes；Linking arm 2 and tower body 1 is connected, and is provided with horizontal position locating piece in the hinged place of linking arm 2 and crane arm 3, linking arm 2 and counter-jib 4, horizontal Position locating piece can be the positioning pin of activity inserting, when linking arm 2 and crane arm 3 and linking arm 2 and counter-jib 4 are in level Positioning pin is plugged when position, it is fixed, and guarantees the normal use of derrick crane.

The preceding hydraulic cylinder extension bar that fixed oriented 3 direction of crane arm extends on 1 leading flank of tower body of 2 lower section of linking arm 5, preceding hydraulic cylinder extension bar 5 lays two along 1 width direction interval of tower body, and hydraulic cylinder extension bar 5 is arranged in parallel before two, stretches It holds and is mutually hinged with the lower surface of crane arm 3；Fixed oriented 4 direction of counter-jib is prolonged on 1 trailing flank of tower body of 2 lower section of linking arm The rear hydraulic cylinder extension bar 6 stretched, rear hydraulic cylinder extension bar 6 lay two along 1 width direction interval of tower body, hydraulic cylinder extension after two Bar 6 is arranged in parallel, and the lower surface of telescopic end and counter-jib 4 is mutually hinged；Pass through preceding hydraulic cylinder extension bar 5 and rear hydraulic cylinder extension The contraction of 6 working beam of bar drives the crane arm 3 and counter-jib 4 to be swung down to upright position, folds, resists to complete cantilever crane Typhoon；By preceding hydraulic cylinder extension bar 5 and rear 6 working beam of hydraulic cylinder extension bar stretch drive crane arm 3 and counter-jib 4 to On turn to horizontal position, guarantee the normal use of derrick crane.

Counter-balanced carriage 7 and hoist engine 8 are provided on counter-jib 4, horizontal row is furnished with several clump weights 9, elevator in counter-balanced carriage 7 The hook 11 that lifting clump weight 9 is gone up and down is provided on the steel wire tow line 10 of machine 8；Specifically, matching above clump weight 9 can be located at The movable pulley 12 moved horizontally is set on weight frame 7, and the moving direction of movable pulley 12 is consistent with the orientation of clump weight 9；It is leaning on Setting first fixed pulley 13 horizontal with movable pulley 12 on the counter-balanced carriage 7 of nearly 8 side of hoist engine, positioned at the flat of 8 oblique upper of hoist engine The second fixed pulley 14 is provided on weighing apparatus arm 4, steel wire tow line 10 successively pile warp the second fixed pulley 14, the first fixed pulley 13 and movable pulley After 12, it is fixed on counter-balanced carriage 7 other side opposite with the first fixed pulley 13, hook 11 is located at the fixing end of steel wire tow line 10 and moves Between pulley 12；First fixed pulley 13 and the second fixed pulley 14 carry out steel wire tow line 10 to subtract power while playing the guiding role, It can safely, smoothly put down clump weight 9.

The operating process of the utility model is as follows:

As shown in Fig. 2, according to the special scheme of installing and dismounting, pulling out linking arm 2 first when typhoon will come temporarily and rising The positioning pin of weighing arm 3, linking arm 2 and 4 hinged place of counter-jib.

Then it by 8 unwrapping wire of hoist engine being arranged on counter-jib 4, drives the hook 11 for hanging with clump weight 9 to fall, will match Pouring weight 9 is put on ground, later 8 take-up of hoist engine, increase hook 11, then hang next piece of clump weight 9, is driven its whereabouts； Movable pulley 12 is moved to 13 direction of the first fixed pulley while unloading clump weight 9 one by one, and hook 11 is made to rise to and will hang Clump weight 9 right above, avoid mutual collision, guarantee that clump weight 9 falls steadily.

(the gravity of the side after quantity that clump weight 9 specifically unloads is folded according to crane arm 3 after unloading part clump weight 9 Depending on, the purpose is to guarantee that 2 both ends of linking arm are horizontal always), by the contraction of preceding hydraulic cylinder extension bar 5 drive crane arm 3 to Lower rotation, that completes crane arm 3 folds (i.e. crane arm 3 turns to vertical state).

Remaining clump weight 9 is unloaded, to all clump weights by 8 unwrapping wire of hoist engine being arranged on counter-jib 4 again later It after 9 all unsnatch, is rotated down by the shrinkage band dynamic balancing arm 4 of rear hydraulic cylinder extension bar 6, completes folding (i.e. for counter-jib 4 Counter-jib 4 turns to vertical state).

After crane arm 3 and counter-jib 4 all fold, fixation appropriate carried out to it complete derrick crane preventing The whole operation process of model typhoon.
