Description
Technical field
The invention belongs to subsurface boring technical fields, and in particular to a kind of Directional Drilling operation on the sea clamping drilling rod safety dress
It sets.
Background technique
The construction of Directional Drilling land-sea crossing project is to draw reaming, marine Recycling of drill rod operation on land.At sea recycling is bored
When bar, after the single drill pipe shackle that drilling machine is held tightly, a large amount of drilling rods in tail portion can be fallen into the sea because of rebound.Therefore it needs a kind of new
Type device draws tail portion drilling rod to be recycled, it is made not depart from operation ship.
Summary of the invention
For above situation, the present invention provides a kind of Directional Drilling operation on the sea clamping drilling rod safety devices, on solving
The problem of stating provides more effective technical solution.
The technical solution adopted by the invention is as follows: a kind of Directional Drilling operation on the sea clamping drilling rod safety device, including support,
Pull rod and taper pullover, the support are fixedly mounted in front of drilling machine in lower margin square hole, and the support totally two, each branch
Seat is fixedly connected by one end of a removable pin I and pull rod, and the other end of the every pull rod is connected by removable pin II
Taper pullover is connect, taper pullover and drilling machine are separately positioned on the two sides of support, and drilling rod is fixed in taper pullover and and drilling machine clamp
Mouth is connected.
Further, the drilling rod is hung with slips by lifting lug, and the drilling rod is stuck in inside taper pullover by slips.
Further, the support and pull rod setting at an angle, the support and pull rod institute angle Du Kegen
It is adjusted correspondingly according to drilling rod and horizontal plane institute are angled.
Further, the inner conical surface taper of the taper pullover is adapted with the male cone (strobilus masculinus) taper of the slips.
Further, the taper of the male cone (strobilus masculinus) of the inner conical surface and slips of the taper pullover is 1:3.
Further, two supports or two pull rods are symmetrical arranged about drilling rod.
Beneficial effects of the present invention: 1, at sea Recycling of drill rod when, prevent drilling machine hold tightly single drill pipe shackle after, tail portion
Drilling rod is fallen into the sea because of rebound, tail portion drilling rod to be recycled is drawn using the device, to prevent drilling rod separating operation ship；2, it ties
Structure is simple, easy to use, safe and practical.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention.
Fig. 2 is schematic top plan view of the invention.
Wherein: 1, support, 2, pull rod, 3, drilling rod, 4, slips, 5, taper pullover, 6, removable pin I, 7, removable pin II.
Specific embodiment
In order to which the purpose of the present invention, technical solution is more clearly understood, with reference to the accompanying drawings and examples to the present invention
It is described in further detail, it should be understood that described herein the specific embodiments are only for explaining the present invention, is not used to the present invention
The restriction of protection scope, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention.
Referring to Fig.1, Fig. 2, the Directional Drilling return and drag drilling rod safety device, including support 1, pull rod 2 and taper pullover 5.
Support 1 is fixedly welded in front of drilling machine in lower margin square hole using steel plate reinforcement, and support 1 totally two, each support 1 is logical
It crosses a removable pin I 6 to be fixedly connected with one end of a pull rod 2, the other end of every pull rod connects taper by removable pin II 7
Pullover 5, taper pullover 5 and drilling machine are separately positioned on the two sides of support 1.Drilling rod 3 be arranged in taper pullover 5 and with drilling machine jaw
It is connected, slips 4 is hung with by lifting lug on drilling rod 3, when needing clamping drilling rod 3, the slips 4 for being suspended on 3 top of drilling rod is pasted
In 5 inside of taper pullover, then embraces drilling rod 3 and be inserted into taper pullover 5, to block drilling rod 3.
Two supports of the device or two pull rods are symmetrical arranged about drilling rod, support 1 with pull rod 2 is at an angle sets
It sets, 2 angle degree of support 1 and pull rod can be adjusted correspondingly according to drilling rod 3 and horizontal plane institute are angled.Taper pullover 5
The taper of inner conical surface is adapted with the taper of the male cone (strobilus masculinus) of slips 4, the cone of the male cone (strobilus masculinus) of the inner conical surface and slips 4 of taper pullover 5
Degree is 1:3, and drilling rod 3 can be stuck in taper pullover 5 just.Slips 4 is designed as multiple-piece slips, and multiple-piece slips is compared
It is lighter in three-chip type slips.Be additionally provided with and be easily installed or the earrings of lifting operation on taper pullover 5, earrings altogether there are two.
At sea when Recycling of drill rod, tail portion drilling rod is because rebound generates a setback force, and at this moment, slips 4 is embraced by slip insert
Tight drilling rod 3,3 male cone (strobilus masculinus) of slips and 5 inner conical surface contact of taper pullover, and then two pull rods 2 and 1 stress of support is driven to lead
Draw drilling rod 3, so that drilling rod 3 no longer retreats.When discharging drilling rod 3, drilling machine draws drilling rod, so that slips 4 follows drilling rod 3 to drilling machine
Direction is moved out taper pullover 5, and after drilling rod 3 is detached from taper pullover 5, the spin-up of slips 4 is left brill by cucurbit on pulling lifting lug
Bar.Primary trip-out work is completed.
The device of our company setting is to set pull rod to 3600mm, and supporting stand size is set as 180*180*1000, support
The height for being embedded in ground underfooting is set as 140mm, and pull rod and support are arranged to the angle of design, in actual use, pull rod
It can be adjusted accordingly according to drilling rod with horizontal plane institute angle degree with the angle of support.The device apply in general to not less than-
20 DEG C of marine environment.
