Abstract
An opened type hydraulic dynamic clamp safety door interlocking locking device is composed of a dynamic clamp body, a safety door, a hydraulic motor, a manual change-over valve, a connecting connector, an interlocking wire, a fixing holder, a screw, an interlocking wire sleeve, an interlocking device and the like. The interlocking device is arranged on the manual change-over valve, the interlocking device is composed of a connector, an adjusting nut, a fastening nut, a spring and a locking pin. A connector body on the interlocking device is connected and fixed on a supporting holder of the manual change-over valve through a screw thread. The interlocking wire is arranged between the interlocking device and the safety door, one end of the interlocking wire is connected with the locking pin of the interlocking device, and the other end is fixed on the safety door. The safety door is closed well, the valve core locking of the manual change-over valve is released, the power clamp can operate normally, the safety door is opened, the valve core of the manual change-over valve is locked, and the power clamp can not operate, thereby achieving the purpose of interlocking protection. The opened type hydraulic dynamic clamp safety door interlocking locking device has simple structure, and is safe and reliable.
Description
Technical field
The utility model relates to the safe automatic safety device of the security protection facility, particularly open hydraulic power tongs of oil drilling and well workover usefulness Power Tong.It belongs to oilfield machinery security protection technology field.
Background technology
At present, oil drilling and well workover Power Tong are the common equipments that unloads drilling rod, sleeve pipe and oil pipe operation on the oil field, are divided into open-type, closed type and survivor of a murder attempt's type by the binding clip pattern, and the open-type Power Tong is a kind of of the most normal employing.The open-type Power Tong generally all requires to be equipped with safety door, and oilfield safety needs now, also requires to accomplish that safety door shuts, and Power Tong could run well; Safety door is opened, and Power Tong can not turn round, and plays the interlock protection, prevents the operator in maloperation or careless, and health or other object enter opening, security incident occurs.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, safe and reliable open hydraulic power tongs safety door interlock locking device.
Technical solutions of the utility model are made up of Power Tong caliper, safety door, hydraulic motor, hand-operated direction valve, jointing, train line, holder, screw, train line cover and interlock etc.But safety door is folding, is installed in Power Tong caliper opening part.On hand-operated direction valve, be provided with the interlock that constitutes by fittings body, adjusting nut, fastening screw nut, spring and stop pin.Fittings body on the interlock is fixed on by thread connection on the supporting seat of hand-operated direction valve, and stop pin and spring are contained in the fittings body.Be provided with train line between interlock and the safety door, train line one end is connected on the stop pin of interlock, and an end is fixed on the safety door by jointing.Train line overlap an end by holder and screw on the Power Tong caliper, an end is against on the fittings body of interlock.Train line is connected with stop pin, and train line transmission in the train line cover plays the spool effect of locking hand-operated direction valve; Spring plays reset response; Adjusting nut is adjusted the installation length of train line, and it is consistent with the safety door switch motion to guarantee that stop pin moves, and also tight with fastening screw nut.Safety door is closed, and the stop pin on the train line pulling interlock is removed the spool locking on the hand-operated direction valve, and hand-operated direction valve can normal running, and Power Tong runs well; Safety door is opened, and train line drives the stop pin on the interlock, and the spool on the locking hand-operated direction valve can't be operated hand-operated direction valve, and Power Tong plays safety door and is not related to regard to cisco unity malfunction, the interlock protection purpose that Power Tong can't turn round.It is characterized in that: be provided with interlock on hand-operated direction valve, described interlock is made of fittings body, adjusting nut, fastening screw nut, spring and stop pin.Fittings body on the interlock is fixed on the supporting seat of hand-operated direction valve by thread connection.Be provided with train line between interlock and the safety door, and train line one end is connected on the stop pin of interlock, an end is fixed on the safety door.
The beneficial effects of the utility model are, have improved the security reliability of open hydraulic power tongs, and simple in structure, convenient disassembly, its economy and obvious social benefit.
