It is fixedly connected with the pulley spindle of movable pulley, the free end winding pulley blocks of drawstring and the second fixed pulley, under the pulley spindle of movable pulley
End is fixedly connected with hook.The lifting elevator utilizes pulley principle, construction personnel is lifted equipment, it is narrow to start from space
Small substation uses.But since the structure of the lifting machine is simple, small, in hoisting heavy, pulling in a flash,
Speed increases, and acceleration increase, due to the characteristic of reaction force, then one end of transverse arm can cause larger vibrations, easily topple over
Or substation's loop wheel machine of turning on one's side, bad stability, so as to be produced to operator dangerous.In addition, artificial or machine is carried by drawstring
When rising weight, during rising, it is also possible to the change of larger speed is produced, therefore it is easy in the weight of the transverse arm other end
Generation shakes or rocks, so that influencing substation equipment falls on corresponding accurately position up.
The content of the invention
It is an object of the invention to provide a kind of substation's loop wheel machine, to solve, because loop wheel machine is small, to influence loop wheel machine mechanism steady
The problem of qualitative difference, make the steady lifting heavy of arm.
In order to achieve the above object, basic technology scheme of the invention is：A kind of substation's loop wheel machine, including base, frame body,
Jack machinism and balanced controls, the frame body are equipped with the vertical supporting frame being installed on above base, the vertical supporting frame
Upper end is provided with horizontal arm；The jack machinism includes pulley, and pulley is installed on one end of horizontal arm, is wound with pulley
Drawstring, one end of drawstring are connected with force piece, and the other end of drawstring is equipped with hook, and the balanced controls include air pump, active
Cylinder, slave cylinder, the pulley are connected with output shaft, and air pump is connected with input shaft, the input axis connection of the air pump
On the output shaft of pulley, the active cylinder is equipped with air inlet and gas outlet, and air pump connects the air inlet of active cylinder, actively
Cylinder is fixedly mounted on the inside of horizontal arm, and an active cavity is equipped with the active cylinder, is slided on the inner wall of active cavity
Dynamic sealing is connected with active piston, and through hole is offered in the middle part of active piston, and check valve, active cavity are fixedly connected with through hole
Active compression spring is internally provided with, one end of the active compression spring is fixedly connected on active piston, and the other end of active compression spring is fixed
It is connected on the inner wall of active cavity, connection slave cylinder is fixed in the gas outlet of active cylinder, and one is equipped with the slave cylinder

The operation principle of this programme is：Vertical supporting frame, the upper end peace of vertical supporting frame are provided with above base
Equipped with horizontal arm, this belongs to the frame structure of substation's loop wheel machine, and one end of horizontal arm is equipped with pulley, drawing is wound with pulley
Rope, one end connection force piece of drawstring, the other end of drawstring is connected with hook, tangles weight, startup force piece, weight with
Hook moves up, this belongs to the jack machinism of substation's loop wheel machine, and air pump is connected with by shaft on pulley, air pump it is another
One end connects active cylinder, and active cylinder connects slave cylinder, weight slide block is equipped with slave cylinder, and weight slide block is fixed and connected
Balance rope is connect, the side of horizontal arm is connected to by stabilizer, this belongs to the balanced controls of substation's loop wheel machine；
Weight is hung on hook, starts force piece, then pulley starts to rotate, the operating of the rotation driving air pump of pulley；
When the speed of equipment lifting weight changes larger, the rotation driving air pump fast turn-around of pulley, makes air
The air aeration quantity of pump becomes larger, then the active piston in the whole active cylinder of gas push is moved to active inside cavity, meanwhile,
Active compression spring in active cavity is compressed, while gas is entered in active cylinder by check valve, since active cylinder is received
To the impact of a large amount of gases, then gas enters slave cylinder and promotes relay piston inside slave cylinder, then relay piston
On relay piston bar rapidly promote weight slide block to be slided to the other end of horizontal arm, increase the pressure of the horizontal arm other end
Power, the larger pulling force suffered by balanced transversal arm lifting heavy side；
