Description

A kind of automatic anticollision device for pulley of petroleum well drilling derrick
The present invention is a kind of automaton, is meant a kind of pulley of petroleum well drilling derrick automatic anticollision control device especially.
Existing petroleum well drilling derrick bumps for preventing the derrick coaster, all uses following these two kinds of devices.A kind of device is on the position of 4 meters of distance crown fixed pulley groups, hawser across the derrick two ends is installed, one end of hawser is fixed, the other end is moved to below the derrick, driving a simple and crude tripping gear that constitutes with the iron wire crotch, then is the mechanical air valve of executing by weight below again.During work, in case when having the running block accident of fishhook and rising to the warning line that forms by hawser, just make that the iron wire of tripping gear is stretching, weight falls, and at this moment, the air valve handle relies on the weight action of gravity, turn over certain angle, impel brake gas circuit ventilation work, realize skidding.It is long that this method exists the weight fall time, the steel wire bending, and it is malfunctioning to break off relations, and weight is stuck, problem and hidden danger such as freezes during low temperature, causes brake failure, the accident of coaster collision.Another kind of device is on the capstan barrel of wirerope feeler lever to be installed, and drives mechanical air valve with feeler lever.When travelling block rises, in case rise to risk altitude, twine neat wirerope and will just drive feeler lever, make air valve work, braking brake.This matching requirements wirerope must be arranged around neatly, otherwise is easy to generate misoperation, makes Control Failure.These prior aries, being provided with the travelling block operating position shows, watch the hoisting depth of travelling block below by the author, operation by rule of thumb, like this under night or complicated weather conditions, or, prior art reliability and safety are affected because under the influence of composite factors such as operator's self fatigue and error, the symptom of a trend of accident is a lot.
The purpose of this invention is to provide and a kind ofly can show the coaster height, when coaster rises to certain altitude, carry out braking brake automatically, make coaster pulley of petroleum well drilling derrick automatic anticollision control device out of service safely and reliably.
According to the present invention, a kind of like this automatic anticollision device for pulley of petroleum well drilling derrick is provided, it comprises, one by the power sensor, extension spring, the height restriction device that cable wire is formed; The position sensing device of a differentiation coaster position; Signal to described height restriction device and position sensing device output carries out limiting altitude to be differentiated, and sends the main control unit of electromagnetic valve actuating signal.
According to feature more specifically of the present invention, the present invention also comprises a coaster lever position indicator; Height restriction device of the present invention also comprises a pretension adjusting device; Position sensing device of the present invention comprises three hall probes that are installed in crown, one to the hall probe output signal rise, the position sensor signal treatment circuit of decline and position discrimination.
Compared with prior art, advantage of the present invention is significant.First, derrick coaster lever position indicator of the present invention makes the operator can intuitively differentiate the coaster position, and the coaster that numeral shows and the relative distance of crown overhead traveling crane are brought great convenience to the operator, especially under night or IFR conditions, the present invention shows safety, reliable especially.The second, whole device reaction speed is fast, is pure velocity of electrons from picking up signal to carrying out brake.The 3rd, the control of limiting altitude coaster anticollision is monitored simultaneously by two paths of signals, reliability, and safety increases greatly.The 4th, choosing of all spare and accessory parts all can be considered compliance of the present invention under the adverse circumstances during enforcement, as waterproof, anti-mud, freeze proof etc.
The present invention uses at the oil field derrick, has market and promotional value widely.
From detailed description, can better understanding be arranged to the present invention below in conjunction with accompanying drawing.
