Technical field
The utility model belongs to industrial furnace field, more particularly to a kind of multiple spot lifting adaptive equalization device, is mainly used in
The lifting of external equipment in stove.
Background technology
Multiple spot lifting adaptive equalization device is at present in mine field using more.But the device belongs to vertical lifting, by
It is unrestricted when highly being applied on mine, so being widely used.But in industrial furnace field, because industrial premises highly has
Limit, the device when using shared height space it is too big, effective lifting altitude is too low, it is impossible to use, therefore, is needing multiple equilibrium
During lifting, the method for manual adjustment rope length can only be used, inefficiency, accuracy is poor, time-consuming to take a lot of work.
The content of the invention
In order to solve problems of the prior art, it is adaptive that the purpose of this utility model is to provide a kind of multiple spot lifting
Bascule, to solve at present when needing multiple equilibrium to lift by crane, the operation of manual adjustment rope length.
In order to realize foregoing invention purpose, the utility model uses technical scheme as described below：
A kind of multiple spot lifts by crane adaptive equalization device, including support frame, is set respectively in the left and right sides of support frame upper end
There is support platform, some boom hoistings are provided with support platform, boom hoisting includes fixed pulley group, movable pulley, slide, liquid
Cylinder pressure and steel wire rope, the hydraulic cylinder is horizontal to be fixedly connected in support platform, and the piston rod of hydraulic cylinder is with that can prop up
The slide connection that support platform upper surface horizontally slips, the movable pulley is horizontal to be fixed on slide, the fixed pulley group bag
Include the fixed pulley A being fixedly connected in support platform, fixed pulley B, fixed pulley C, fixed pulley D, wherein fixed pulley B and fixed pulley C
Respectively positioned at the front and rear sides of movable pulley and close to the left side edge of support platform, fixed pulley A and fixed pulley D are respectively fixedly connected with
On the left surface and right flank of support platform, the steel wire rope pile warp fixed pulley A, fixed pulley B, fixed pulley C and determines cunning successively
Take turns D；The hydraulic cylinder in boom hoisting in the support platform of the left and right sides is connected by an oil pipe respectively into and out of hydraulic fluid port.
Further, the boom hoisting set in the support platform is at least a set of.
Further, the slide slip is fitted in support platform upper surface and is provided with chute.
Due to using above-mentioned technical proposal, the utility model has following superiority：
The utility model causes the steel wire rope of each Heave Here by the movable pulley on Hydraulic Cylinder slide and slide
Stress is identical, it is ensured that the balance of lifting, and each hydraulic cylinder into and out of hydraulic fluid port be connected so that the steel of each Heave Here
Cord stress can be automatically adjusted, so as to reach adaptive equalization, the Stability and veracity of adjustment be improved, while also significantly
Improve operating efficiency.
Brief description of the drawings

Fig. 2 is Fig. 1 top view；
In figure：1- movable pulleys；2- slides；3- hydraulic cylinders；4- fixed pulley groups；5- oil pipes；6- steel wire ropes.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described in detail to the technical solution of the utility model.
As shown in Figure 1, 2, a kind of multiple spot lifting adaptive equalization device, including support frame, the left and right in support frame upper end
Both sides are respectively arranged with support platform, are provided with some boom hoistings in support platform, boom hoisting include fixed pulley group 4,
Movable pulley 1, slide 2, hydraulic cylinder 3 and steel wire rope 6, the hydraulic cylinder 3 is horizontal to be fixedly connected in support platform, hydraulic cylinder
3 piston rod is connected with the slide that can be horizontally slipped in support platform upper surface, and the movable pulley 1 is horizontal to be fixed on cunning
On seat 2, the fixed pulley group 4 includes fixed pulley A, fixed pulley B, fixed pulley C, the fixed pulley D being fixedly connected in support platform,
Wherein fixed pulley B and fixed pulley C are respectively positioned at the front and rear sides of movable pulley and close to the left side edge of support platform, fixed pulley A
Be respectively fixedly connected with fixed pulley D on the left surface and right flank of support platform, the steel wire rope 6 successively pile warp fixed pulley A,
Fixed pulley B, fixed pulley C and fixed pulley D；The hydraulic cylinder in boom hoisting in the support platform of the left and right sides into and out of hydraulic fluid port point
It is not connected by an oil pipe 5.
The boom hoisting set in the support platform is at least a set of.
The slip of slide 2 is fitted in support platform upper surface and is provided with chute.
Adaptive equalization of the present utility model adjusts process：
1st, in initial state, each hydraulic cylinder in the support platform of the left and right sides is in middle position, by each hydraulic cylinder and
Oil pipe is filled after hydraulic oil, sealing closing；
2nd, after lifting starts, because the fixed pulley group of each boom hoisting only changes the direction of steel wire rope, steel wire is not changed
The size of rope tension, so the lifting power of each boom hoisting is exactly the tension force of steel wire rope, movable pulley transmission cord tension（Also
It is lifting power）And act on hydraulic cylinder, because the hydraulic cylinder oil inlet of each boom hoisting connects together, oil-out is also connected in
Together, when the power that the steel wire rope tension of each boom hoisting is delivered on hydraulic cylinder is identical, hydraulic cylinder is failure to actuate, when each rises
When power on the hydraulic cylinder of device for hoisting is unequal, the hydraulic cylinder meeting automatic telescopic of each boom hoisting passes through the action of hydraulic cylinder
To promote the movable pulley on slide and slide to move left and right, and then the length after steel wire rope pile warp fixed pulley D is adjusted, until each
The hydraulic cylinder force of individual boom hoisting is identical, so as to ensure that the tension force on each steel wire rope is identical, also ensures that the flat of lifting
Weighing apparatus property.
