Abstract
The utility model relates to a connecting structure for an engineering drill rig and a drill rod, comprising a taper sleeve 2, a conical body 4 and locking nuts 5. The drill rod can be connected or disassembled conveniently, and the utility model having the advantages of favorable stiffness, strength, coaxial degree, sealing performance, rapid and convenient disassembly and assembly and low labor intensity is a connecting structure for the drill rod with the value of popularization.
Description
The utility model relates to the syndeton that a kind of engineering driller drilling rod connects usefulness.
Engineering driller is in heavy caliber creeps into, drilling rod is to work under the situation of low speed, large torque, so drilling rod should possess enough stiffness, intensity and axiality, do not leak owing to also require it under 40 kilograms of mud pressures, to work, therefore better seal must be arranged.Rig all has certain drilling depth when creeping into, will interconnect between the drilling rod, and demolition, installation are frequent, and it is quick and convenient so just to require drilling rod to connect dismounting, to increase work efficiency and to reduce labor intensity.Drilling rod connection at present is divided three classes substantially.The first kind is for being threaded, and moment of torsion is by the screw thread transmission, and therefore, dynamic load is big more, and screw thread is tight more, makes the locking rear thread be difficult for unclamping, and has increased the weight of probing labour intensity; Second class is that flange connects, and flange is by 2 pin torsion passes, and 6 bolts connect, and so just make its upper and lower drilling rod be difficult for centering, and dismounting is difficult for; The 3rd class is that tooth embedding mode connects, though solved the contradiction of above two big class drilling rods, torsion pass and dismounting all touch the mark, and its upper and lower tooth embedding gap is big, so intensity, stiffness are relatively poor, axiality and sealing are also bad, and use is restricted.Therefore, it is very necessary designing a kind of novel drilling rod syndeton.
The purpose of this utility model promptly is to design a kind of novel engineering driller drilling rod draw bail according to the problem that prior art exists, and has that drilling rod connects easy accessibility, is connected firmly, the moment of torsion transmission effect is good, the characteristics of good sealing effect.
How the purpose of this utility model realizes if being described in detail in detail with reference to the accompanying drawings.
Accompanying drawing 1 is the utility model mounting structure figure.
Accompanying drawing 2 is the utility model section of structure.
1 is the drilling rod body among the figure, and 2 is coning sleeve, and 8 is the O RunddichtringO, and 4 is the tapering body, and 5 is nut, and 6 is retaining pin, and 7 is spring, and 8 is pin, and 9 is the embedding of cone tooth, and 10 is the embedding of tapered sleeve tooth, and 11 is the retaining hole, and 12 is screw thread, and 13 are retaining, and 14 is the power-assisted hole.
With reference to accompanying drawing, the utility model is by coning sleeve 2, tapering body 4 and locking screw Female 5 form. Coning sleeve 2, tapering body 4 are contained in respectively the two ends of drilling rod, tapering Body 4 is a garden cylindrical shell, and its rear end is welded on the drilling rod, and its front portion is one to the top The conial tube that tilts, the outer middle side part of this conial tube is provided with " O " RunddichtringO, should The outside, tapering body 4 middle parts is provided with a plurality of outstanding identical cone teeth of size, spacing Embedding 9 has retaining hole 10 on it. Coning sleeve 2 is a garden tube, its rear end welding On drilling rod, front end is gradually big conial tube of opening, before its tapering and the tapering body 4 Section's tapering is identical, and these coning sleeve 2 anterior outsides are provided with screw thread 12, and the tip is provided with cone Cover dental inlay 10, tapered sleeve dental inlay 10 sizes, spacing are identical with cone dental inlay 9. On it Also have retaining hole 11, locking nut 5 is garden ring nut, and there is screw thread 12 inboard, There is gear 13 on the top, and its outside is provided with a plurality of power-assisteds hole 14 and a retaining device, ends Unloading device is by retaining pin 6, form around thereon spring and the pin 8 of outer end thereof. Retaining pin 6 can snap in retaining hole 11 under spring 7 effects. The utility model uses The time, earlier two drilling rods that welded tapering body 4, coning sleeve 2 to plugging in tapering Body 4 just in time inserts within the coning sleeve 2, and cone dental inlay 9 and tapered sleeve dental inlay 10 are just in time Staggered snapping in screws off nut 5 then, because the effect of gear 13 and screw thread 12 is logical Cross power-assisted hole 14 power-assisteds, nut 5 is screwed after, tapering body 4 and coning sleeve 2 is namely Be stuck tightly, the O RunddichtringO has played sealing function. So far, two Drilling rod namely connects together tightly, cone dental inlay 9 and the cone of torque by being stuck Cover dental inlay 10 is transmitted. At this moment, rotational pin 8 puts down retaining pin 6, once nut 5 derotations, retaining pin can snap in a plurality of retainings hole 11 automatically. Work as drilling rod Use when needing dismounting, extract retaining pin 6, insert power-assisted hole 14 with bar, unclamp Behind the nut 5, can separate drilling rod.
The utility model is used for the engineering drilling rod connects, have obvious superiority. At first, connect because drilling rod is the tapering setting, eliminated drilling rod and be difficult for neutralization The shortcoming in gap. Sealing ring has prevented stagnant leakage. Pass square with the tooth embedding but use nut check , screw thread can not locked tighter and tighter so that moment of torsion transmits. In addition, retaining device Nut can not be refunded, eliminated the possibility that drilling rod comes off. With in the past various connections Mode is compared, and has stiffness, intensity, axiality, sealing and has all obtained fine The characteristics of ground solution, and demolition, installation are convenient, rapid, greatly alleviated workman's labor Fatigue resistance is a kind of engineering driller drilling rod syndeton with promotional value.
