Description

The two rocking arms in rotatable seat ground, the inside/outside backguy suspended mixture bar of filling the span of a man's arms

Technical field

The utility model relates to power system project of transmitting and converting electricity transmission line construction field, especially super-pressure, UHV transmission line engineering shaft tower lifting group is vertical.

Background technology

Because each shaft tower type is different, landform, geological condition, transport routes and unit in charge of construction's actual conditions around the group vertical rod tower are different, and the tower erection method can be divided into: integral body is stood up and the vertical two large classes of minute system of solutions.And steel tower is because physical features and weight factor adopt minute system of solutions cube formulas more.For highly high, weight is large, and is with a varied topography, and root is opened large steel tower, should adopt the rocker pole group vertical.

Rocker pole is the crane gear that is formed by combining by rocking arm, mainmast and shaft principal post, the pole position generally is positioned at the steel tower center; rocking arm is used arm of when lifting; what the rocker pole arm was different with general tower crane is that rocking arm is the variation of finishing the amplitude of hanging piece by the changing-breadth system of arm end, and swinging up and down of arm is defined as rocking arm.

Backguy rocker pole in more rocker pole adopts and suspend in the present stage line construction adds revolution and supports between mainmast and pole shaft principal post, can 360 ° of rotations.This type of pole advantage is: convenient, to rotate flexibly during lifting, and the lifting scope is wide, and efficient is high, can be one-sided, bilateral lifts by crane simultaneously, and compare with the instrument such as tower crane, greatly reduce the expense that produces in the assembling process, economical rationality.But this pole shortcoming is: (1) is suspended, the restriction of interior backguy, belongs to the pin-ended type in the mechanics of materials, length factor μ=1, and lift heavy is light.When running into the large steel tower of weight, can only strengthen main material, strengthen the pole cross section, virtually increase expense, workload and difficulty when increasing construction; (2) during the vertical steel tower of group, hoisting weight is by heavy gradually light, when steel tower height during far above the pole overall length, because such pole dead weight is large, promotes difficulty, wastes time and energy.

Summary of the invention

In order to overcome the defective that existing rocker pole lift heavy is not enough, promote difficulty, design under a kind of equivalent material specification, lift heavy is large, can be in group tower process with highly increasing, and become at any time the mixing pole of suspended holding pole by the rocker pole dismounting.

The technical scheme that its technical problem that solves the utility model adopts is:

The two rocking arms in a kind of rotatable seat ground, the inside/outside backguy suspended mixture bar of filling the span of a man's arms comprises mainmast, rocking arm, principal post, rotary system, tackling system, changing-breadth system, and wherein: the following principal post of rotary system lower end is the chassis, can make whole pole main body base ground; Pivoting support is arranged on the pole middle part, the following part shaft of pivoting support seat ground, and the above part order of connection of pivoting support is: principal post-four-way section (connecting rocker arm)-mainmast.The pole rotating disk adopts the pivoting support structure, and the above part of rotating disk can 360 ° of rotations, and during rotation, backguy is motionless; By four-way section connecting rocker arm, rocking arm all arranges changing-breadth system and tackling system between mainmast, principal post, can about, left and right adjusting, front 1/3 place of rocking arm is provided with anticollision device, collision-prevention device, it is detachable that this puts collision device; Lifting rope forms tackling system by principal post is inner, rocking arm is inner and the fairlead at top jointly with the lifting tackle pulley; The luffing rope is inner by principal post, the fairlead of mast top, jointly forms changing-breadth system with the luffing tackle pulley; The mainmast top is rotation holding pole head, plays the inside/outside backguy with the body of the tower of the vertical steel tower of group and forms hinged structure; When pole seat ground used, the utility model was that an end is fixed an end hinged structure in mechanics of materials pressure bar stabilization, length factor μ=0.7, and mostly be middle flexibility bar, promoted greatly the lifting capacity of pole; Because pole has adopted rocking arm, efficiently solve the lifting problem that large of steel tower base section is opened member simultaneously.

Along with the tower erection height increases, pole institute lift heavy amount is gradually light, and the lifting amplitude is gradually little, at this moment, can extract the punching axle that pole is connected with rocking arm out under the pole Light Condition, by the pole corner block rocking arm is unloaded to ground; Remove simultaneously pivoting support and following part rod body section, the bottom connects support system, sets four groups of bearing ropes, and the top is rotary holding pole head, namely can be assembled into inside/outside backguy suspended holding pole, is easy to lifting, and lift heavy, lifting amplitude are fit to, and be convenient, flexible.

Described utility model main body is Q345;

Described utility model main body adopts welding procedure;

With bolts between the described utility model body of rod and the body of rod;

Described mainmast top is provided with rotary system;

Described rotary system adopts 360 ° of pivoting supports;

Described rocking arm is partly established tackling system and changing-breadth system;

The punching shaft type is adopted in described rocking arm and pole coupling part;

Described rocking arm for preventing and the pole collision, adds anticollision device (detachably) at the rocking arm front end when luffing;

The beneficial effects of the utility model are during construction, when not increasing dead weight, to increase the lift heavy amount that risen, and rotate flexibly; After tower erection reach a certain height, detachable became the suspended holding pole form again, has reduced deadweight, and according to lift heavy light actual conditions gradually, lifting is convenient.The engineering tower erections such as the 1000kV UHV transmission line construction of implementing for China provides another effectively new the selection.
