Abstract
The utility model discloses an antilocking device for a drilling tool. The antilocking device comprises a coupling belt. The coupling belt is formed by arc-shaped parts surrounding the external diameter of a drilling rod and an ear plate extending out of each arc-shaped plate, wherein a pin hole is arranged on each ear plate; the coupling belt is locked on the drilling rod via the pin holes through a pin roll; an arc-shaped antiloosening snapping plate extends out of the upper end of the coupling belt along an axial direction; the antiloosening snapping plate is matched with a baffle block on the external diameter of the lower end of a protective joint to form an antirotation structure; the other end of the coupling belt is provided with a snapping block containing a U-shaped neck; the U-shaped neck is clamped on the external side of the drilling rod; and the external side has two sides or four sides. The protective joint of a top driving device and a lower drilling tool are locked in a threaded connection state via a mechanical structure, so thread loosening is prevented; and torque of disassembling the lower joint coupling screw thread of the drilling rod is transmitted via the structure, so damage to the drilling screw thread is reduced.
Description
Technical field
The utility model belongs to the technical field of all-hydraulic water drilling rig and coal bed gas drilling machine rig tool, specifically a kind of locking device of top-drive device lifting and upper shackle.
Background technology
The rig of existing top drive, use the condition next top drive unit of two sides and square kelly, by box cupling, drilling rod is promoted to a high position, clamp by Type B drilling rod lower end or drilling rod is collapsed button by the pincers of its structure, then use top-drive device by lower box cupling shackle, under top-drive device, fall behind, add holding equipment by manipulator or other drilling rod is accommodated to shackle, because top-drive device is connected by screw buckle with hoop, cannot ensure whether to connect tight, easily shine into drilling tool and come off, drilling tool drops to well head and shines into major accident.
Utility model content
The purpose of this utility model is to provide a kind of top-drive device and promotes and transfer, rotate a kind of locking device of detaining shackle on drilling tool, be applicable to box cupling band two sides and cubic drilling tool, can be used for promoting and transfer, swivel shackle, upper button, mainly play transmitting torque and prevent the device that drilling tool is threaded off.
For achieving the above object, the technical solution adopted in the utility model is: a kind of drilling tool locking device, it is characterized in that: there is box cupling band, box cupling band has arch section and the extended otic placode of arch section of parcel drilling rod external diameter, otic placode is provided with pin-and-hole, pin-and-hole makes box cupling locking on drilling rod by bearing pin, box cupling band upper end edge axis direction is extended with the locking clamp of arc, described locking clamp coordinates with the block being arranged on the external diameter of protection joint lower end, form anti-rotation structure, the other end of box cupling band is connected with the fixture block with U-shaped draw-in groove, U-shaped draw-in groove is clamped in drilling rod the outside in two sides or four directions.
The utility model beneficial effect is: project organization main purpose is that the protection joint of top-drive device and lower drilling tool are threaded connection under state, are separately pinned by frame for movement; prevent that screw thread from releasing; and unload screw threads of coupler under drilling rod and pass through this structure transmitting torque, the injury that alleviates thread of drilling tool.Concrete operation situation: top-drive device and drill rod thread button collapse button (screw thread pine one button); After being installed, drilling tool locking device is promoted to eminence, after accommodating, lower drill pipe slip use top-drive device to carry out shackle, utilize drilling tool coupling band two sides and cubic structure, rig is connected by locking device, prevent that box cupling from coming off with transmitting torque for upper shackle.(locking by drilling tool locking device transmitting torque of the present invention and upper end button); Top drive is outwarded winding drilling rod is moved to mouse hole, dismantle drilling tool locking device shackle drilling rod (because of before collapse a loose button, unusual good the unloading of this button), the next top drive unit that closes connects well head to a upper drilling rod, installs that locking device promotes, swivel shackle.
Brief description of the drawings
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use state reference map of the present utility model.
Detailed description of the invention
A kind of drilling tool locking device as shown in Figure 1, 2; there is box cupling band 7; box cupling band has arch section and the extended otic placode 2 of arch section of parcel drilling rod external diameter; otic placode is provided with pin-and-hole; pin-and-hole 6 makes box cupling locking on drilling rod by bearing pin; box cupling band upper end edge axis direction is extended with the locking clamp 5 of arc; described locking clamp 5 coordinates with the block 8 being arranged on the external diameter of protection joint lower end; form anti-rotation structure; the other end of box cupling band is connected with the fixture block 3 with U-shaped draw-in groove, and U-shaped draw-in groove is clamped in drilling rod the outside in two sides or four directions.If locking device when rotate under the drilling rod of its underpart clamping drives, locking clamp 5 runs into stopping of block 8 makes it can not continue rotation, can transmitting torque, and prevent from protecting joint to separate with the dropout of drilling rod, cause danger.
