Description

A kind of quick-locking device
Technical field
The utility model is related to technical field of oil extraction equipment more particularly to a kind of quick-locking devices.
Background technology
During oil drilling, on casing head of well head, for controlling the blowout apparatus of high pressure oil, gas and water.In well oil When atmospheric pressure is very high, preventer can close well head and (shut), when weighted mud is pressed into out of drilling rod, have four-way under flashboard, can The mud by gas cut is replaced out, increases the pressure of fluid column in well, to push down the ejection of high-pressure oil gas.
However in preventer pressure-bearing makes a trip experiment, due to about 3 meters or so of drilling rod height and manual operation is dangerous, A quick-locking device is now designed for installing drilling rod.
Utility model content
The purpose of this utility model is and a kind of quick locking dress proposed in order to solve shortcoming in the prior art It puts.
To achieve these goals, the utility model employs following technical solution:A kind of quick-locking device, including work Make platform, the top of the workbench is connected with preventer by screw rod, and the top of the preventer is connected with mould by connecting rod Intend drilling rod, the top of the simulation drilling rod is equipped with locking buckle, and the top slide of the locking buckle is arranged with sliding block, the cunning The top of block is through oil cylinder is arranged with, and the locking buckle is made of locking pin, spring and oil inlet, and oil inlet is arranged on lock On the bottom side outer wall being tightly buckled.
As further describing for above-mentioned technical proposal:
There are two the spring is set altogether, and two springs are symmetrical about the vertical center line of locking buckle, and spring is in dish Shape.
As further describing for above-mentioned technical proposal:
The outside diameter of the simulation drilling rod is equal to the internal diameter of location hole that locking buckle bottom opens up.
As further describing for above-mentioned technical proposal:
The vertical center line of the preventer, simulation drilling rod and locking buckle is in same horizontal line.
As further describing for above-mentioned technical proposal:
The oil pipe for leading to oil is connected between the oil cylinder and locking buckle.
In the utility model, the quick-locking device, firstly, since the setting of locking buckle, in constructing operation, works as cunning When block downlink, simulation drilling rod can tightly be lockked so that it, which is installed, consolidates, secondly as the setting of oil cylinder, Ke Yitong Cross to logical hydraulic fluid port lead to by so that locking check lever overcome spring force, by its retraction location hole, such mode enables to The locking device can achieve the purpose that automatic unlocking, finally, due to which this locking device is realized by the elastic force of spring Lock and unlock so that its at work, operation it is more convenient, practicability is stronger.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.
With reference to Fig. 1-2, a kind of quick-locking device, including workbench 1, the top of workbench 1 is connected with anti-by screw rod Spray apparatus 2, the top of preventer 2 are connected with simulation drilling rod 3 by connecting rod, and the top of simulation drilling rod 3 is equipped with locking buckle 4, lock The top slide of tight buckle 4 is arranged with sliding block 5, and the top of sliding block 5 is through oil cylinder 6 is arranged with, and locking buckle 4 is by locking pin 7, bullet Spring 8 and oil inlet 9 form, and oil inlet 9 is arranged on the bottom side outer wall of locking buckle 4.
Spring 8 is altogether there are two settings, and two springs 8 are symmetrical about the vertical center line of locking buckle 4, and spring 8 is in dish Shape, the outside diameter of simulation drilling rod 3 are equal to the internal diameter of location hole that 4 bottom of locking buckle opens up, preventer 2, simulation drilling rod 3 It is in same horizontal line, is connected between oil cylinder 6 and locking buckle 4 for logical oil with the vertical center line of locking buckle 4 Oil pipe.
Simulation drilling rod 3 can be locked by locking buckle 4, and a certain amount of lubricating oil, workbench 1 are stored in oil cylinder 6 For a kind of detachable structure, preventer 2 is for closing well head in the operation process such as formation testing, well workover, completion, preventing gas blowout accident Occur, full envelope and half sealed two kinds of functions and is integrated, have it is simple in structure, it is easy to operate, it is high pressure resistant the features such as, be that oil field is commonly used The security seal wellhead assembly for preventing blowout.
Operation principle:In an experiment, it needs the preventer 2 of built-in analog drilling rod 3 being positioned on workbench 1 first, work Platform is moved into press, and the action of oil cylinder 6 allows 5 downlink of sliding block that simulation drilling rod 3 is connected automatically on sliding block 5;Rapid abutting joint work Dress is mainly made of load housing, disk spring 8, locking check lever etc., and tooling has locking check lever to stretch out and two kinds of shapes of retracting State, original state are stretching state, and disk spring 8 compresses locking check lever, is allowed to head and stretches out load housing location hole;It retracts Locking check lever can be overcome 8 elastic force of spring, positioning of being retracted by state by 9 fuel feeding of logical hydraulic fluid port in load housing Hole;After logical 9 fuel cut-off of hydraulic fluid port and release, locking check lever is automatically switched to original state.
The preferable specific embodiment of the above, only the utility model, but the scope of protection of the utility model is not This is confined to, in the technical scope that any one skilled in the art discloses in the utility model, according to this practicality Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
