In order to address the above problem; According to the technical scheme of the utility model, drilling well rotating disk reaction torque release control device comprises magnetic patch, disk, Hall element, support, counting relay and electromagnetic valve; It is characterized in that: said disk is provided with through hole; This disk is solidly set on the said disk middle spindle, and the outer wall of this disk is provided with by the equally distributed groove of circumference, in this groove, places said magnetic patch; Hall element detects magnetic patch, and output pulse signal is to counting relay, and power supply passes through counting relay and is connected with the coil of electromagnetic valve, and the brake inlet end of normally closed air feeding apparatus of the inlet end of source of the gas through tracheae line and electromagnetic valve and rotating disk is connected; The output of electromagnetic valve is connected through the brake control end of normally closed air feeding apparatus of tracheae line and rotating disk, and the brake outlet side of normally closed air feeding apparatus of rotating disk is connected with the rotating disk brake clutch.
The utility model is through being provided with magnetic patch on disk, when rotating disk reversing disc rotated, Hall element detects magnetic patch, and output pulse signal is confirmed the position of rotating disk reversing to counting relay by counting relay; When discharging reaction torque, the position of confirming the rotating disk reversing is set, on counting relay when rotating disk is inverted to desired location; Power supply is through the coil power supply of counting relay to electromagnetic valve; Electromagnetic valve is opened, and source of the gas gets into the rotating disk brake clutch through the tracheae line, and rotating disk is stopped operating.Remove the rotating disk brake, only need click the SR on the counting relay, closed electromagnetic valve, the rotating disk brake clutch discharges, and brake is removed.
A preferred version according to the described drilling well rotating disk of the utility model reaction torque release control device; Said source of the gas also is connected with an end of brake switch through the tracheae line; The other end of brake switch is connected through the brake control end of normally closed air feeding apparatus of tracheae line and rotating disk, can realize thus that the driller operates with control automatically to carry out simultaneously; When rotating disk also is not inverted to desired location, driller's brake switch that closes, source of the gas gets into the rotating disk brake clutch through the gentle pipeline of brake switch, and rotating disk is stopped operating.
The beneficial effect of the described drilling well rotating disk of the utility model reaction torque release control device is: the utility model can be controlled the application position of drilling well rotating disk reversing automatically; The rotating disk counter-rotating arrives desired location, and control stops operating rotating disk automatically, the safe release reaction torque; And; Driller's operation can be carried out with automatic control simultaneously, can prevent effectively that the quick reversing of rotating disk from causing the generation of drilling tool dropout accident, is fit to industries such as oil, metallurgy and uses very much.
Description of drawings
Fig. 1 is the connection sketch map of the described drilling well rotating disk of the utility model reaction torque release control device.
Fig. 2 is described disk 5 structural representations of the utility model.
The specific embodiment
Referring to Fig. 1; Drilling well rotating disk reaction torque release control device; Be made up of brake normally closed air feeding apparatus 3, magnetic patch 4, disk 5, Hall element 6, support 7, counting relay 10, electromagnetic valve 11, source of the gas 14 and brake switch 13 of rotating disk brake clutch 1, rotating disk, said disk 5 is provided with through hole, and this disk 5 is solidly set on the said disk middle spindle 2; The outer wall of this disk 5 is provided with by the equally distributed groove 15 of circumference, in this groove 15, places said magnetic patch 4; Said Hall element 6 detects magnetic patch 4; Output pulse signal is to counting relay 10; Can adopt during practical implementation with Hall element 6 through support 7 be fixed on disk 5 near; And the end face of Hall element 6 is corresponding with the outer wall of disk 5, and Hall element 6 is connected with counting relay 10, and support 7 is fixed on the mount pad 9 of rotating disk 8; Power supply 12 is connected with the coil of electromagnetic valve 11 through counting relay 10, and source of the gas 14 is connected through the brake inlet end of normally closed air feeding apparatus 3 and an end of brake switch 13 of tracheae line and inlet end, the rotating disk of electromagnetic valve 11; The other end of the output of electromagnetic valve 11 and brake switch 13 all is connected through the brake control end of normally closed air feeding apparatus 3 of tracheae line and rotating disk, and the brake outlet side of normally closed air feeding apparatus 3 of rotating disk is connected with rotating disk brake clutch 1.
