Description
Technical field
The utility model relates to technical field of hydraulic, and particularly oil hydraulic motor overcomes the reaction torque oil hydraulic circuit automatically.
Background technique
At present, adopt when power drilling tool is implemented directional drilling at the bottom of the hole, the hydraulic power head rig must have assisting agency to overcome that the reverse torque of power drilling tool does not change to keep drilling rod at the bottom of the hole; In the oil hydraulic circuit of general rig; The hydraulicdirectional control valve of on the drill power head oil hydraulic circuit, installing is a P type valve, and when the handle of hydraulicdirectional control valve placed meta, the oil hydraulic motor return opening led directly to fuel tank; The unit head oil hydraulic motor is in the forward and backward quick condition; Therefore can not reach the locking purpose, existing drill power head oil hydraulic circuit can not realize overcoming the function of reaction torque at the bottom of the hole, brings very big inconvenience to drilling construction.
The model utility content
The purpose of the utility model is to provide a kind of oil hydraulic motor to overcome the reaction torque oil hydraulic circuit automatically; Simple, convenient; Advantage with reliable in action has solved the hydraulic power head rig and has used the difficult problem that the power drilling tool reaction torque was difficult to be overcome at the bottom of the hole when power drilling tool crept at the bottom of the hole.
The purpose of the utility model is achieved in that a kind of oil hydraulic motor overcomes the reaction torque oil hydraulic circuit automatically; But fuel tank, oil hydraulic pump, unit head oil hydraulic motor, pressure-limit valve, one-way valve pressure-regulating and pressuring-limiting valve and hydraulicdirectional control valve cooperate through hydraulic pipe line and are communicated with; Hydraulicdirectional control valve is three six-way valves; The filler opening of oil hydraulic pump is communicated with fuel tank; The oil hydraulic pump oil outlet feeds fuel tank through the oil-feed mouth of pipe and the fuel-displaced mouth of pipe, first hydraulic pipe line, unit head oil hydraulic motor, second hydraulic pipe line, the collection tube mouth of hydraulicdirectional control valve, the oil return mouth of pipe of one-way valve, hydraulicdirectional control valve successively; Second hydraulic pipe line is communicated with fuel tank through Adjustable pressure limiting valve; The oil outlet of oil hydraulic pump is communicated with fuel tank and also feeds fuel tank through pressure-limit valve through the fuel-displaced mouth of pipe of the oil return oil-feed mouth of pipe, the oil return of hydraulicdirectional control valve; Second hydraulic pipe line is through the collection tube mouth of Pilot operated check valve and flow stop valve connection hydraulicdirectional control valve, and an end mouth of pipe of the import of Pilot operated check valve and flow stop valve is connected the collection tube mouth of hydraulicdirectional control valve jointly, common second hydraulic pipe line that is communicated with of the other end mouth of pipe of the outlet of Pilot operated check valve and flow stop valve.
The utility model has increased by one and has overlapped the device (hydraulically-controlled one-way valve and flow stop valve) of the oil hydraulic motor counter-rotating that is automatically locked in oil hydraulic circuit; After increasing this device on the oil hydraulic circuit of control rig; When power drilling tool creeps at the bottom of the rig employing hole, after the flow stop valve is closed, need not make this oil hydraulic circuit carry out any other control action; Hydraulicdirectional control valve is in the meta state; The unit head oil hydraulic motor possesses the function that overcomes reaction torque at the bottom of the hole automatically, and at this moment, operator also can be operated hydraulicdirectional control valve control positive and negative rotation of motor at any time with adjustment drilling tool face or carry out operation such as drilling tool unloading.The device of the utility model and above-mentioned increase is arranged on by the rig floor, adopts the principle of locked power motor oil return to overcome reaction torque, promptly utilizes the meta control oil channel of hydraulicdirectional control valve; Adopt Pilot operated check valve to pin oil circuit automatically, and take union valve group (being hydraulically-controlled one-way valve and flow stop valve) to guarantee the safety of the state that normally creeps into, in conventional drill power head oil hydraulic circuit, increase a hydraulic control lock valve (Pilot operated check valve) and a flow stop valve; Generally speaking, the flow stop valve is closed all the time and (when using drill power head to creep into, should be kept the flow stop valve to be in opening state; When adopting anchor head unloading drilling tool; Must the flow stop valve be opened), when operation hydraulicdirectional control valve handle carried out hydraulic pressure hydraulic oil switching-over work, the unit head oil hydraulic motor just changeed, reverses all unaffected; When power drilling tool is implemented directional drilling at the bottom of the employing hole; Do not change to keep drilling rod for the reaction torque that overcomes power drilling tool at the bottom of the hole, should make hydraulicdirectional control valve be in the meta state, Pilot operated check valve can stop unit head oil hydraulic motor counter-rotating oil return; Thereby power drilling tool reaction torque at the bottom of the counteracting hole; During power drilling tool, that the flow stop valve is open-minded at the bottom of not using the hole, promptly recover the state that normally creeps into.The utility model is simple, convenient, have the advantage of reliable in action, has solved the hydraulic power head rig and has used the difficult problem that the power drilling tool reaction torque was difficult to be overcome at the bottom of the hole when power drilling tool crept at the bottom of the hole.
