Specific embodiment
To a kind of of the present invention, there is bispin and the double-beam gantry lifting from defense structure with reference to embodiment and accompanying drawing
Machine is described in detail.
As shown in Fig. 1～Fig. 6, a kind of of the present invention has bispin and the double-beam gantry crane from defense structure, including
There is girder 1, the supporting leg 3 being connected for support girder 1 with girder 1, it is supported on the trolley body on girder 1, described dolly machine
Structure includes the trolley frame 11 of driving lower edge girder 1 movement being supported on girder 1 and in travelling mechanism 6 by trundle 15,
And it is arranged on two groups of completely identical in structure jack machinisms that hook block weight is used on trolley frame 11, described girder 1 upper cover
Have for preventing trolley body and girder 1 to be subject to the defense structure 2 of erosion of exposing to the sun and rain, the drive mechanism of described jack machinism
It is reel and the drive mechanism of fixed pulley axis rotation in opposite direction.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, described defense structure 2 includes for keeping out the wind to trolley body and girder 1
The shape of a saddle cover 22 taken shelter from rain, and be arranged on the π shape structure for reinforcing shape of a saddle cover 22 intensity of shape of a saddle cover 22 inner side
Reinforcement 21, described reinforcement 21 is fixedly welded on described girder 1, described shape of a saddle cover 22 pass through reinforcement 21 with
Described girder 1 is fixedly connected.Described reinforcement 21 is provided with more than 2, and the present embodiment is provided with 3.
Defense structure 2 is welded on the outside of girder 1 by reinforcement 21, and shape of a saddle cover 22 is in the shape of a saddle, and the left and right sides can
Think truss structure, for increasing the security and stability of structure, the uniform three reinforcement floors in inner side, described shape of a saddle cover 22 is
Thin plate, acts primarily as and protects trolley and girder from the climatic effect such as expose to the sun and rain, extend the use of trolley and girder
The effect in life-span.By doing force analysis to girder, it is understood that girder institute main inclusion two parts loaded, trolley is certainly
Weight and lifting material weight, due to power application point not on girder so that girder is while bearing pressure, also can
Acted on by moment of torsion, heterocoelous defense structure and Main Girder Welding are integrated, the mechanics mould of simply supported beam is changed from structure
Type, improves the stress of girder, increased the stability that each mechanism runs.
As shown in Figure 5, Figure 6, described drive mechanism includes and is arranged on trolley frame 11 by being connected to the defeated of motor 7
The reel 5 that decelerator on shaft drives, two ends are arranged on the fixed pulley axis 14 on trolley frame 11, are fixed on fixed pulley axis 14
The fixed pulley group being made up of the fixed pulley 13 of more than 2, and be arranged on below fixed pulley group and by steel wire rope 10 with fixed
The running block being made up of plural movable pulley 12 that assembly pulley connects, the lower end of described running block is connected with suspension hook
16, wherein, one end of described steel wire rope 10 is fixedly connected on described trolley frame 11, and the other end is fixedly connected on described volume
On cylinder 5.
As shown in fig. 7, the winding arrangement of described steel wire rope 10 is: one end of steel wire rope 10 is fixed on trolley frame 11
Afterwards, with immediate movable pulley 12 and fixed pulley axis 14 start by movable pulley, fixed pulley, movable pulley, fixed pulley order successively
It is fixed on after being wound to last movable pulley 12 on described reel 5.The winding structure of this steel wire rope can make reel 5 He
Fixed pulley axis 14 realize opposite direction rotation so as to be cancelled each other a part by the inertia force that turning moment is formed, thus reduce right
The pressure of girder 1.
In drive mechanism, motor 7 passes through decelerator 4, and band movable reel 5 rotates, and such as raising weight then makes steel wire rope 10
Around coiling 5, reel rotates counterclockwise, and as shown in Figure 6, Figure 7, steel wire rope 10 drives movable pulley 12 successively, fixed pulley 13, due to
The other end of steel wire rope 10 is fixed on trolley frame 11, will be shifted up for this whole running block, under the drive of steel wire rope 10, fixed
Pulley spindle 14 rotates clockwise.Reel 5 rotates counterclockwise the inertia force just phase rotating clockwise generation with fixed pulley axis 14
Instead it is possible to realize, from offsetting a part, thus the pressure to girder for the minimizing, strengthening the stability that mechanism runs.Under weight
During fall, spool shaft rotates clockwise, and fixed pulley axis rotate counterclockwise, the inertia force also contrast of generation.So that girder
Stress performance is obviously improved, and stability and security performance are obviously improved.
