Abstract
The invention relates to a rapid drill stem hoisting adapter comprising a drill stem, a lifting ring, a linkage sliding sleeve, fixture blocks, and a cone. The outer walls of the fixture blocks are arc-shaped and provided with drill stem threads, and the inner walls of the fixture walls are tapered. The diameter of the lower end of each fixture block is large. A tapered body formed by a plurality of fixture blocks is suspended on the linkage sliding sleeve, the lifting ring passes through the linkage sliding sleeve, and the lower part of the lifting ring is connected with the tapered body. The tapered body with a small-diameter upper end and a large-diameter lower end is matched with the inner walls of the fixture blocks, the fixture blocks are connected with the drill stem threads, a damping lock is arranged between the lifting ring and the linkage sliding sleeve, the fixture blocks are expanded by lifting the tapered body of the lifting ring upwards so that the threads on the outer walls of the fixture blocks are connected with the threads on the inner wall of the drill stem to press the lifting ring to enable the tapered body to be apart from the fixture blocks, the fixture blocks are retracted, and the threads on the outer walls of the fixture blocks are separated apart from the threads on the inner wall of the drill stem. Therefore, the rapid drill stem hoisting adapter can be rapidly connected with and separated from the fixture blocks, and has advantages of easiness and convenience for hoisting of the drill stem, high operation efficiency, and low labor intensity of workers. The invention can meet requirements of on-site construction, and has obvious economic benefits.
Description
Technical field
The present invention is that oil drilling hangs the instrument that drilling rod is used, and is a kind of quick dop of drilling rod that hangs.
Background technology
In oilfield drilling, the drilling rod that lies in ground be sling and the drilling rod in the well is lain in ground, in this process, needing linkage is connected drilling rod with travelling block, be to use the male thread of plug to be connected at present, plug is suspended on the travelling block, then drilling rod is hung with the box thread of drilling rod, adopting plug to hang drilling rod needs to unload screw thread, it is cumbersome to work, and labor strength is big, inefficiency, engineering time is long, can not satisfy the site operation requirement.
Summary of the invention
The objective of the invention is to design a kind of quick dop of drilling rod that hangs, make it in that to hang drilling rod easy, high efficiency, labor strength is low.
The object of the present invention is achieved like this: comprise drilling rod, also comprise suspension ring, interlock sliding sleeve, fixture block, cone, the outer wall of fixture block is a circular arc, on the outer wall of fixture block drill rod thread is arranged, and the fixture block inwall is conical, lower end diameter is big, the several piece fixture block is formed cone and is suspended on the interlock sliding sleeve, and suspension ring pass the interlock sliding sleeve, and the suspension ring bottom is connected with cone, the little lower end diameter of cone upper end diameter cooperates with the fixture block inwall greatly, and fixture block is connected with drill rod thread.
Between suspension ring and the interlock sliding sleeve damping lock is installed.
The invention has the beneficial effects as follows: go up lifting ring cone and strut fixture block, the fixture block outer wall thread is connected with the drilling rod inner thread, press down suspension ring, cone and fixture block are thrown off, receive in the fixture block, fixture block outer wall thread and drilling rod inner thread are thrown off, therefore, the present invention can be connected and throw off fast with drilling rod, it is easy to hang drilling rod, high efficiency, and labor strength is low, can satisfy the site operation requirement, have remarkable economic efficiency.
Description of drawings
Fig. 1 is the assembling drawing of the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described.
Embodiments of the invention comprise suspension ring 1, interlock sliding sleeve 2, fixture block 4, cone 5, drilling rod 6, the outer wall of fixture block 4 is a circular arc, on the outer wall of fixture block 4 drill rod thread is arranged, fixture block 4 inwalls are conical, and lower end diameter is big, and several piece fixture block 4 is formed cone and is suspended on the interlock sliding sleeve 2, suspension ring 1 pass interlock sliding sleeve 2, suspension ring 1 bottom is connected with cone 5, and the little lower end diameter of cone 5 upper end diameter cooperates with fixture block 4 inwalls greatly, and fixture block 4 is threaded with drilling rod 6.Between suspension ring 1 and the interlock sliding sleeve 2 damping lock 3 is installed, suspension ring 1 can not taken off in interlock sliding sleeve 2 easily, be convenient to carry and use.
When needs are sling drilling rod 6, the present invention is put into drilling rod 6 internal threads, and last lifting ring 1 is connected the cone 5 up fixture blocks 4 that strut under the suspension ring 6, the outer wall thread of fixture block 4 is connected with the inner thread of drilling rod 6, thereby drilling rod 6 can be sling, when putting down drilling rod 6, press down suspension ring 1, cone 5 and fixture block 4 are thrown off, fixture block 4 can move inward, and fixture block 4 outer wall threads and drilling rod 6 inner threads are thrown off, and it can be taken out.
