Description
Art
The present invention relates to a kind of water drilling quick-acting connector of water drilling with anti-locking function, drilling machine, water drilling etc. are particularly suitable for use in
The position that connection drill bit, drilling pipe and lengthening extension bar etc. are often unloaded.
Background technology
The conventional methods such as current drilling machine connection drill bit, drilling pipe and lengthening extension bar are to be equipped with High angle using standard screw thread
With the characteristics of conical surface righting centering, this connection method advantage is simple in construction, and rigidity is good, has the disadvantage, the very time-consuming expense of shackle
Power, Connection Time length can also be got rusty or even occur lock-up condition because of screw thread position water enchroachment (invasion).Patent No. ZL200410083954.x
The appearance of quick safety connecting mechanism technology, having started drilling machine, water drilling etc. can be unloaded drill bit, drilling pipe and lengthening with free-hand moment
The new height of extension bar.But this technology fails to popularize over 10 years, discovery patent structure design of tracing it to its cause is still suffered from
These weak points, have impact on its Popularization And Development below.Weak point is one is it sets cylinder before and after employing connection cone
Righting section, manufacture difficulty is big, and sets sealing in small end righting Duan Shangshe O circle sealings above, deep endoporus, easily because of impurity, hole
The reasons such as footpath corrosion, can cause seal failure.Weak point the second is connect lock tube auto-lock function deficiency, the self-locking that patent is provided soon
Angular data is 5 degree to 7 degree, this in the quiescent state self-locking it is feasible, but boring bar tool be vibrations working condition, easily release failure, often go out
Existing boring procedure drilling pipe is come off, and lock tube Self-locking angle need to be turned down significantly.The three of weak point are the cone connections that the patent is provided
Face angle according to be 8 degree Ban between self-locking and non-self-lock-ing to 9 degree, actually it be unfavorable for it is free-hand unload, rational grafting
Face angle should be non-Self-locking angle, and lock tube should then develop to low value self-locking angular direction.Weak point is the fourth is fast and safely connect machine
Structure be as be between rig, water drilling and drilling pipe to be unloaded with its moment function realize its be worth, that is, under normal circumstances,
Connect female joint soon long-term with drilling pipe, scrap and just unload down even up to drilling pipe, it may appear that connect soon female joint because it is long when
Between do not load and unload and by the locked situation of corrosion, female joint screwed connection position is connect soon to be needed with anti-locking function.Also one
Weak point is that quick safety connecting mechanism design technology is bad, manufacturing cost it is high, it is necessary to do structural reform with meet it is low into
The need for this big production.
The content of the invention
In order to overcome the poor efficiency and the patent No. of screwed connection in current drilling machine bindiny mechanism
ZL200410083954.x quick safety connecting mechanisms remain weak point, can further develop the patented technology again
