Abstract
The utility model provides an automatic open-close control device for top-drive cock, which is adaptable to the fields of petroleum and geological drill, and which can reliably control cocks to open and close in time during normal operation and well blowing accidents. The automatic open-close control device for top-drive cock comprises a cylinder holder arranged on a torque beam, a cylinder is arranged on the cylinder holder through cylinder holder pins, and one end of a shifting fork is connected with the other end of the cylinder through cylinder piston rod pins. The torque beam is provided with an opening in the middle for the shifting fork to pass through, and a shifting fork holder is fixed at one side of the torque beam. A pinhole of the shifting fork is arranged on the shifting fork holder through a connection pin, the other end of the shifting fork is inserted into a slot outside a cock shutter, and the cylinder and the cock shutter are respectively arranged at both sides of the torque beam.
Description
Technical field
What the utility model belonged to oil, geological drilling field is that cock automatic shutter control device is driven on a kind of top.
Background technology
At present, the method of the top being driven the control of cock automatic shutter is the both sides that two execution oil cylinders are installed in the cock shutter, cock shutter in the direct push-and-pull, the opening and closing of cock in the realization, owing to carry out the oil cylinder asynchronism for two, can cause the stuck of cock shutter, open, closing control is unreliable, brings danger to drillng operation.
The utility model content
The purpose of this utility model is to provide a kind of suitable oil, top, geological drilling field to drive cock automatic shutter control device, in the process of normal operation and processing blowout, can in time control cock reliably and open and close.
In order to achieve the above object by the following technical solutions: comprise the oil cylinder holder, the oil cylinder holder is arranged on the torque beam, oil cylinder by oil cylinder fixedly seat pin be arranged on the oil cylinder holder, one end of described connection shift fork is connected with the other end of oil cylinder by the oil cylinder piston lever pin, perforate in the middle of the torque beam, connecting shift fork passes in the middle of torque beam, connect the side that the shift fork holder is fixed on torque beam, pin-and-hole is arranged on the connection shift fork holder by connecting pin in the middle of connecting shift fork, the other end that connects shift fork inserts in the groove of going up the cock shutter outside oil cylinder, last cock shutter lays respectively at the both sides of torque beam.
Described oil cylinder by oil cylinder fixedly seat pin be hinged on the oil cylinder holder.
One end of described connection shift fork is hinged by the other end of oil cylinder piston lever pin and oil cylinder.
Pin-and-hole is hinged on by connecting pin and connects on the shift fork holder in the middle of the described connection shift fork.
The other end of described connection shift fork inserts in the groove of going up the cock shutter outside
Adopt advantage of the present utility model to be: the oil cylinder arrangement convenience, solve last cock shutter and moved up and down process stuck problem easily, in time the cock switching is gone up in control reliably.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Embodiment
As shown in drawings, cock automatic shutter control device is driven on the top, comprise oil cylinder holder 1, the oil cylinder holder is fixed on the torque beam 4, oil cylinder 3 by oil cylinder fixedly seat pin 2 be hinged on the oil cylinder holder, an end that connects shift fork 6 is hinged with the other end of oil cylinder by oil cylinder piston lever pin 5, connect the side that shift fork holder 7 is fixed on torque beam, pin-and-hole is hinged on the connection shift fork holder by connecting pin 8 in the middle of connecting shift fork, perforate in the middle of the torque beam, connecting shift fork passes in the middle of torque beam, the other end that connects shift fork inserts in the groove of going up cock shutter 9 outsides oil cylinder, last cock shutter lays respectively at the both sides of torque beam.Cock 10 inner ball valves are opened, are closed in the upper and lower mobile realization of last cock shutter.The be dynamically connected swing of shift fork of oil cylinder telescopic band, what connect cock shutter on the fork controls moves up and down the opening and closing of cock in the realization.
