Изобретение относитс к управлению установками и предназначено дл точной регулировки величины возмущающей силы инерционного вибратора.The invention relates to the control of installations and is intended to fine-tune the magnitude of the disturbing force of the inertial vibrator.

Известно устройство дл управлени инерционным вибратором, содержащее систему трубопроводов дл подвода рабочей жидкости в гидроцилиндры с порщн ми-дебалансами и регулирующие органы с манометрами 1.A device for controlling an inertial vibrator is known, which comprises a piping system for supplying a working fluid to hydraulic cylinders with pressure balances and regulating bodies with pressure gauges 1.

Недостаток известного устройства заключаетс в низкой надежности и сложности регулировани , в результате чего не обеспечиваетс точность регулировани положени поршней-дебалансов.A disadvantage of the known device lies in the low reliability and complexity of adjustment, as a result of which the accuracy of the adjustment of the position of the pistons-unbalances is not ensured.

Цель изобретени повышение точности регулировани положени порщней-дебалансов .The purpose of the invention is to improve the accuracy of adjusting the position of the unbalance.

Эта цель достигаетс тем, что устройство снабжено двум последовательно расположенными гидродомкратами и двум силовыми цилиндрами, установленными в раме, при этом гидродомкраты соединены между собой плитой, с которой св заны также щтоки силовых цилиндров, рабочие полости которых соединены с соответствующими и равными им по объему полост ми гидроцилиндров вибратора.This goal is achieved by the fact that the device is equipped with two successive hydraulic jacks and two power cylinders installed in the frame, while the hydraulic jacks are interconnected by a plate, which also connects the power cylinder shafts, the working cavities of which are connected to the corresponding cavity equal to them in volume mi hydraulic cylinders vibrator.

Кроме того, плита снабжена указателем положени перемещени щтоков силовых цилиндров .In addition, the plate is provided with an indicator of the position of movement of the rods of the power cylinders.

На чертеже изображено предлагаемое устройство дл управлени инерционным вибратором.The drawing shows the proposed device for controlling an inertial vibrator.

Claims

The device contains a piping system 1-4 for supplying the working fluid to the hydraulic cylinders 5 and 6 with pressure debalances 7 and 8 and regulators 9 and 10 with electrical contact gauges 11 and 12. Two hydraulic jacks 13 and 14 and two power cylinders 15 and 16 are installed in frame 17. The hydraulic jacks 13 and 14 are interconnected by a plate 18, to which the rods 19 and 20 of the power cylinders 15 and 16 are connected, the working cavities 21 and 22 of which are connected to the corresponding cavities 23 and 24 of the hydraulic cylinders 5 and equal in volume and 6 of the vibrator 25. The plate 18 is provided with a pointer 26 to the position of the variable rods 19 and 20, power cylinders 15 and 16. In the upper part 27 of the frame 17, the rod 28 of the hydraulic jack 13 is screwed, and the jack of the hydraulic jack 14 - into the plate 18. To control the hydraulic jacks 13 and 14, use the handles 30 and 31, and for reset loads - valves 32 and 33. Electrocontact pressure gauges 11 and 12 are connected to signal lamps 34 and 35 and electric calls 36 and 37. Cavities 21 and 22 of power cylinders 15 and 16 are connected through a piping system 1-4 to vibrator bushes 38 and 39. In the cavity 23 and 24 of the hydraulic cylinders 5 and 6 of the vibrator 25, the pipelines 40-43 are connected. The pistons 44 and 45 of the power cylinders 15 and 16 through the rods 19 and 20 are rigidly connected to the plate 18. The device for controlling the inertial vibrator works as follows. The pistons 44 and 45 of the power cylinders 15 and 16 are in the lowest position, and the unbalance pistons 7 and 8 are in a balanced initial position, i.e. in the center of the axis of rotation of the cylinders 5 and 6. Thus, a null disturbing force is provided. After the vibrator 25 obtains the working speed, opening the valve 33 of the hydraulic cylinder 13 and raising and lowering the handle 30 of the hydraulic cylinder 14 while its valve 32 is closed, push the rod 29 of the hydraulic cylinder 14, which raises the plate 18 and the rods 19 and 20 and pistons connected to it 44 and 45. At the same time, the rod 28, resting against the frame 17, is sunk. Pistons 44 and 45, rising up, displace the working fluid, which, creating a certain pressure and flow through pipelines 1 and 2, affects the pistons-unbalances 7 and 8, mixing them simultaneously by the same amount to the periphery of the hydraulic cylinders 5 and 6 of the vibrator 25 until a predetermined magnitude of the extinguishing force is obtained. As the unbalance pistons 7 and 8 are mixed, the eccentricity of the vibrator 25 changes. The return of the pistons nonbalance 7 and 8 to its original position occurs in the reverse order. The valve 32 of the hydraulic cylinder 14 is opened and the valve 33 of the hydraulic cylinder 13 is closed. The hydraulic cylinder 13 is swung by the handle 13, while the rod 28, resting against the frame 17, forces the plate. 18 and the rods 19 and 20 connected to it and the rod of the hydraulic jack 14 are mixed down. The pistons 44 and 45 of the power cylinders 15 and 16 are returned to their original position, and under the action of the pressure of the working fluid, the unbalances 7 and 8 of the vibrator 25 are mixed into the zero position to the axis of rotation of the hydraulic cylinders 5 and 6. The lowermost position of the pistons 45 and 44 of the power cylinders 15 and 16 corresponds to the position of the pointer 26 at the mark “O and the position of the pistons of the unbalances 7 and 8 of the vibrator 25 in the center of the axis of the direction of the hydraulic cylinders 5 and 6. By adjusting the hydraulic jacks 13 and 14 of the pressure of the working fluid supplied to the hydraulic cylinders 5 and 6 of the vibrator 25, and reliably change and record the magnitude of the disturbing force. Electrical contact gauges 11 and 12 are set to a certain pressure, and if this pressure is exceeded, signal lamps 34 and 35 and electric calls 36 and 37 are turned on. In this case, the operator switches off the electric motor (not shown), which rotates the vibrator 25. Claims of the invention.
