Description

Anti-loose device for short joint of water tap

Technical Field

The utility model relates to the technical field of petroleum drilling equipment, in particular to a faucet short joint locking device.

Background

The power tap is a device which is arranged on the derrick of the workover rig and is used for providing rotary power. Besides being used for repair operations such as milling, grinding and milling, drilling cement plugs, bridge plugs, salvaging and the like, the drilling tool can also be used for drilling operations such as open-window sidetracking, open-hole drilling, coring and the like.

The power tap is mostly hydraulically driven and is usually composed of a power machine, a hydraulic pump, an oil tank, a control system, a hydraulic pipeline and a liquid motor rotating head (power tap body). When the load is not heavy or the special operation (not the conventional large well bore) is performed, the common water tap, the square drill pipe, the square bushing and the rotary table can be replaced, and the drill pipe string is driven to rotate.

When the existing power faucet works, the large faucet central pipe and the adapter are connected by adopting threads, so that the threads are easy to loosen due to vibration, reverse rotation and the like of the operation, and the thread profile is damaged or safety accidents such as fracture and the like are generated.
