Description
Technical field
The utility model belongs to technical field of petroleum machinery, is related to a kind of rotating disk hydraulic control driving means.
Background technology
The electric drive commonly used in oil-well drilling equipment and Mechanical Driven rotating disk, are primarily present two problems：
One is in normal drilling process, if run out of steam suddenly, to stall can rotating disk, at the same brake automatically engage into
Row brake.In the moment of rotating disk stalling, rotating disk can be reversed because of the reaction torque of drilling rod, and conventional air clutch formula brake
Reaction is relatively slow, and brake torque also than relatively limited, typically plays a part of to accelerate rotating disk stalling.Therefore, if run out of steam suddenly,
After rotating disk is reversed, it is likely that cause drilling rod to thread off and fall in well.In order to avoid such case generation, rotating disk must lose dynamic
Stall at once after power, and can not reverse.
Two is that operation is cumbersome, is typically controlled using two functional units.One is controlling switch, for controlling
The start and stop and steering of rotating disk, another is control handwheel, for controlling the rotating speed of rotating disk.
Utility model content
The purpose of this utility model is to provide a kind of rotating disk hydraulic control driving means, solve in prior art pneumatic tyre from
The brake reaction of clutch formula is relatively slow, and brake torque is also than relatively limited；Two cumbersome problems of operation.
The technical scheme that the utility model is adopted is, a kind of rotating disk hydraulic control driving means, including control handwheel, control
The connection corresponding with proportional amplifier respectively of the left, center, right connecting line of handwheel processed, the left-right signal input line of proportional amplifier and ratio
Two end-coils of magnetic valve are connected respectively, and proportion magnetic valve constitutes a closed-loop path, ratio with balanced valve, hydraulic motor
Magnetic valve is connected with the fuel feeding and oil return pipeline of hydraulic mechanism, and proportion magnetic valve and hydraulic motor are additionally by draining pipeline and liquid
Press mechanism connects.
Rotating disk hydraulic control driving means of the present utility model, are further characterized in that：
Control handwheel has neutral and double-direction control function, that is, it is two-way handwheel to control handwheel, and proportional amplifier is two-wire
Circle amplifier, proportion magnetic valve is twin coil proportioning valve.
The beneficial effects of the utility model are：1) by using hydraulic system driving rotating disk, rotating disk being changed to into hydraulic motor
Drive, when hydraulic motor runs out of steam, by being arranged on hydraulic circuit in balanced valve, lose pilot pressure using balanced valve
The characteristic that hydraulic oil flows through can be blocked afterwards, moment blocks flowing of the hydraulic oil in hydraulic motor, make hydraulic motor keep stopping
Only state；If the reaction torque of drilling rod makes rotating disk have the trend of reversion, oil pressure can be raised automatically in the oil return pipeline of hydraulic motor,
Make hydraulic motor produce reverse moment of torsion with the reversal trend of the rotating disk that contends with, reach the state for making rotating disk keep stalling, prevent down
The generation for turning and threading off.2) by using double-direction control handwheel, original unidirectionally controlled handwheel being changed to into double-direction control handwheel, hand
Wheel middle position is output as " 0 "；Handwheel is turned left, then rotating disk is rotated forward；Handwheel is turned right, then rotating disk reversion；Originally need two operations
The work that step is completed, it is only necessary to which rotating a handwheel just can complete.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, handwheel is 1. controlled, 2. proportional amplifier, 3. proportion magnetic valve, 4. balanced valve, 5. hydraulic motor.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
With reference to Fig. 1, structure of the present utility model is, including control handwheel 1, controls the left, center, right connecting line difference of handwheel 1
Connection corresponding with the proportional amplifier 2 of dual control, the left-right signal input line of proportional amplifier 2 and two end lines of proportion magnetic valve 3
Circle is connected respectively, and proportion magnetic valve 3 constitutes a closed-loop path, proportion magnetic valve 3 and liquid with balanced valve 4, hydraulic motor 5
The fuel feeding of press mechanism and oil return pipeline connect, and proportion magnetic valve 3 and hydraulic motor 5 connect additionally by draining pipeline and hydraulic mechanism
Connect.
Control handwheel 1 has neutral and double-direction control function, is two-way handwheel due to controlling handwheel 1, and proportional amplifier 2 is
Twin coil amplifier, proportion magnetic valve 3 is twin coil proportioning valve, and when the left-hand rotation of handwheel 1 is controlled, controllable hydraulic motor 5 is rotated forward；
When control handwheel 1 is turned right, controllable hydraulic motor 5 is inverted；During control 1 time middle position of handwheel, hydraulic motor 5 stops operating.So as to
The function that a handwheel control rotating disk rotates forward, stops, inverting can be realized, operation extremely facilitates.
Control handwheel 1 cuts off output signal after " 0 " is gone back to automatically by normally opened contact, it is ensured that " 0 " position will not be because of signal
Drift rotates hydraulic motor 5.The oil inlet quantity of hydraulic motor 5 is controlled by controlling handwheel 1, proportion magnetic valve 3, hydraulic motor is made
5 rotating speeds realize stepless speed regulation.
The course of work of the utility model device is：
1) driller's rotation control handwheel 1, control handwheel 1 leaves middle position, and control handwheel 1 sends signal to proportional amplifier 2,
One output end of proportional amplifier 2 sends current signal, drives the one of coil motion on proportion magnetic valve 3, makes ratio
The 3 one direction conductings of example magnetic valve.
2) hydraulic oil passing ratio magnetic valve 3 reaches balanced valve 4, and enters hydraulic motor by one group of valve of balanced valve 4
5, while the hydraulic oil into balanced valve 4 controls another group of valve opening of the balanced valve 4, arrange the oil in hydraulic motor 5
Go out, so as to form hydraulic circuit, the rotary work of hydraulic motor 5.
2) as control handwheel 1 anglec of rotation increases, the output signal electric current of proportional amplifier 2 increases, and proportion magnetic valve 3 is opened
Degree increases, and the hydraulic fluid flow rate for passing through increases, and the rotating speed of hydraulic motor 5 increases.
3) 1 time middle position of driller's operational control handwheel, the normally opened contact controlled in handwheel 1 is opened, it is ensured that output signal disconnects.
3 times middle positions of proportion magnetic valve, the hydraulic oil for making the two entrances of balanced valve 4 is connected with oil return opening, the liquid of the two entrances of balanced valve 4
Force feed loses pressure.
4) after the equal decompression of hydraulic oil of the two entrances of balanced valve 4, balanced valve 4 is closed, and the hydraulic oil in hydraulic motor 5 is put down
Weighing apparatus valve 4 is shut in pump, hydraulic motor 5 is rotated.Even if there is external force to attempt rotational hydraulic motor 5, hydraulic motor 5 is not yet
Can rotate.
