Abstract
The method for improving limit reliability of driller features that a device for monitoring lifting speed and height and controlling lifting power and brake is installed on driller to make the lifting speed in safety range.
Description
The present invention is a kind of method that improves the hoisting system of rig limit anticollision reliability.
The anticollision device of existing oil drilling, geological prospecting rig that drilling well is used, employing be the anticollision device that only has single spacing braking function.The rig tourist bus has corresponding security improvement speed in the differing heights position in whole lifting operation process.If operating personnel operate in strict accordance with operational procedure, this single spacing braking anticollision device can satisfy safety requirements substantially.But, various tourist buses are answered back to the overhead traveling crane accident in the reality, all are in operating personnel's operate miss, and the tourist bus rate of climb surpasses respective specified speed, spacing braking anticollision device loses timely stopping power and causes under huge lifting power or rising action of inertia.
Purpose of the present invention is to provide a kind of limit anticollision device that can help to realize timely spacing braking, improves the method for anticollision reliability.
The objective of the invention is to realize as follows: a cover is installed on rig rig tourist bus hoisting velocity and hoisting depth are monitored, and can promote the device that power is imported and skidding is controlled to rig, comprising: the rangefinder that tests the speed (1), signal processing converter (2), motor switch (3), cable (4), power supply (5).The rangefinder that tests the speed is used for surveying the hoisting depth and the hoisting velocity of rig tourist bus (9); The rangefinder that tests the speed can be mechanical (as: synchronous motor formula), also can be the radar detection formula.Signal processing converter (2) is that a kind of electronics calculates processor, is used for handling the detectable signal of rangefinder (1) of testing the speed, and the "on" and "off" of control motor switch (3).Motor switch (3) is installed on rig and promotes in dynamic Control gas circuit (or circuit) (6) and the skidding control gas circuit (or circuit) (7), promotes the input and the skidding of power in order to control.Connect by cable (4) between them.The mechanical rangefinder that tests the speed can be installed in a certain rotating shaft (8) in the Hoisting System; The rangefinder that tests the speed of radar detection formula can be installed on the drilling derrick (10).When rig promotes operation, this covering device is monitored rig hoisting depth and hoisting velocity, if the rig hoisting velocity surpasses fixing speed, " hypervelocity " signal that signal processing converter (2) will be detected the rangefinder that tests the speed (1) converts " opening " or " pass " that rig promotes motor switch (3) in the dynamic Control gas circuit (or circuit) (6) to, lifting dynamic Control gas circuit (or circuit) " is led to " or " breaking ", thereby remove rig and promote the power input, make rig tourist bus (9) before the limit anticollision height that arrives the limit anticollision device, its speed in action of gravity drops to the fixing speed scope, thereby for limit anticollision create can effective spacing braking condition.Do not stop yet behind the limiting altitude position rising if tourist bus rises to, signal adapter " offside " signal that rangefinder detects that will test the speed converts skidding control gas circuit (or circuit) to.(7) " opening " or " pass " of middle motor switch (3) " led to " skidding control gas circuit (or circuit) or " breaking " carries out skidding.
