Abstract
The utility model relates to a disc type brake control of a petroleum drill and a prospecting drill, which generally adopts a manual relief valve control. An operating lever of the relief valve realizes the control to the relief valve by a set of mechanic changeover device. The operating handle has the problems of large and heavy in volume, troublesome in operation, inconvenient in adjustment, maintenance and poor in trimming character. Some drillers are only equipped with an electric control system, so the braking will lose control in case of power off. In the disc type braking electric and hydraulic dual control system installed in the utility model, an electric control proportional electromagnetic valve control system and a manual relief valve control system are installed, both of which can switch over automatically thus achieve the double insurances. The manual system can be used to keep on controlling the braking once the drill site is power off, which guarantees the safety of the drilling tool and device.
