Description
The present invention is a kind of automatic bayonet socket bindiny mechanism that compensates of band gap that drilling machine is used that relates to, and is specially adapted to the position that auger, water brill etc. connect drill bits, brill tube, the frequent loading and unloading of extension bar and so on that extend.
Existing drilling machine connects drill bit, bores tube, the method for attachment of lengthening extension bar is that screwed connection adds cone and sets upright, locatees, this connection advantage is that simple in structure, good rigidly, concentricity can guarantee with the accuracy of manufacture, it is time-consuming that maximum shortcoming is detained on being, shackle is required great effort very much, and operating efficiency is too low.Number of patent application 00266786X water bores uses the bayonet type quick-connect machanism, pointed out the bayonet type quick connecting method, but there is not safe anti-drop function, in a single day stall suddenly when water drills body of wall, the danger that comes off because of effect of inertia generation bayonet socket easily, this mechanism is with steel ball stake transfer torque with offer the bayonet socket that does not seal in female joint in addition, and the weak point of bayonet socket distortion takes place easily for unreasonable on stressed.The patent application in another this field, application number 01203777X water bores uses quick-connect machanism, it is the three steel ball snap joints transfer torque mechanisms of holding concurrently, it has not only unloads but also slip-off preventing and eliminate joint gap fast, has transmission rigidity, but it belongs to accurate and baroque bindiny mechanism, be not suitable in the site operation of condition harshness, using, maximum weak point in the practicality is in the engineering the drilling construction, inevitably often run into mud, the drilling cuttings machine is assorted is stained with bindiny mechanism's fitting face and the difficulty even stuck of unloading, and in a single day this mechanism come off in boring, do not connect because of passing sliding sleeve, the new difficulty of junk occurs not dragging for.I also once applied for a patent, the bayonet socket bindiny mechanism of application number 022459642 band safety locking pin, attempt to solve quick connection with the bayonet socket mode, solve the slip-off preventing function with safety locking pin, but because the two-part cylinder that it is used is set upright, it there is inevitable fit-up gap, thereby greatly reduce the connection rigidity, jounce easily takes place in the running, thereby but having limited the weak point of its scope of application, this patent application determines to recall.
The purpose of this invention is to provide a kind of band gap bayonet socket bindiny mechanism of compensation automatically, it will solve technically: the first, connect, dismantle quick; The second, gapped automatic compensation function can satisfy the requirement of needed coupling stiffness of drilling machine and smoothness of operation; The 3rd, it is succinct that structural component is wanted, has brill upright opening in harshness, bubble in muddy water, work also harmless extensive compliance and durability: the 4th, have come off function and insert the band gap bayonet socket bindiny mechanism of compensation automatically that can make things convenient for a kind of function admirable that connects again along boring of anti-inertia in case come off.
Our technical scheme is to centralize near the non-self-locking cone from the locking angle with a pair of, use female pushing sleeve of slip and gap compensation stage clip and carry out the bayonet type quick-connect machanism that clearance automatic compensation is a core, for reaching transmission rigidity and avoiding jounce in the running, adopted and allowed female coupling tap be nested with in the female joint cavity to be slidingly matched, all the time push the female coupling tap cover of reasonable length to be close to die nipple face in the male joint with axially putting gap compensation stage clip, reach in and the kilter of rigidity.Our concrete scheme is that the bayonet socket bindiny mechanism that band gap compensates automatically is made up of four parts such as female joint body, male joint, slip female coupling tap cover and gap compensation stage clips, bayonet socket bindiny mechanism is abutted against closely and sets upright from the non-self-locking cone centering of the locking angle, this cone can not only maintain good connection rigidity but also not have self-locking, can rotate to do bayonet socket operation and be convenient to withdraw.On the barrel of the oral area of female joint body, axially open two to three uniform J type bayonet slot, on the corresponding axle journal of male joint, put two to three uniform buckling and torsion pass square boss, buckle in the trip groove of the J type bayonet socket on the female joint body with it, gap compensation stage clip is being pushed slip female coupling tap cover all the time makes the female coupling tap face seamlessly be close to the cone of male joint, slip female coupling tap cover root is equipped with sealing ring, and the chamber that slip female coupling tap on the female joint body is overlapped seals.On the outer rim of slip female coupling tap cover, establish the movable stopper slot of slip female coupling tap cover, on the slip female coupling tap cover chamber wall of female joint body, radially be provided with the movable limited screw of slip female coupling tap cover, limited screw is at the die nipple body pushing slip female coupling tap cover of male joint, the torsion pass boss snaps under the situation of bayonet slot packs into, it can be gap compensation stage clip certain precompression is set, and slip female coupling tap cover then is limited to stay in the female joint body when also making male joint withdraw female joint.Grease holes is also annotated as maintenance in the limited screw hole, and the movable stopper slot that female coupling tap puts is then held concurrently and often is in good lubrication state for oil storage fat groove makes slip female coupling tap cover.Sealing is by cone self fitted seal between cone.In order to solve anti-inertia that bayonet socket the connects function that comes off, measure of the present invention is to have done improvement on bayonet slot, bayonet slot on the female joint body is made the J font, it has the bayonet socket translot that axially enters groove, cross break that buckles torsion pass square boss, and establishes the disconnection proof clamping hook groove as J word eave tile on buckle translot head.Design gaps compensation stage clip has precompressed thrust, and no the pressure of the drill state buckles the torsion pass boss and is crushed on all the time in the trip groove, and has well, and chance stops to bore the inertia falling-off effect that may occur suddenly during anti-drilling body through walls.For this bindiny mechanism is used on the drilling machine, end thrust does not drop on the bearing torque square boss during work, put the cavity bottom of slip female coupling tap cover at the female joint body, if the slip female coupling tap overlaps spacing thrust step, work as public affairs, female joint connects, buckle torsion pass square boss when snapping in bayonet slot translot position, distance (e) between slip female coupling tap cover and the spacing thrust step, generally can be located at the 0.5-1.0 millimeter, and J type bayonet socket translot direct-axis is to staying a gap greater than (e) value (f) to buckling torsion pass square boss, thrust passes on the spacing thrust step when guaranteeing operate as normal, makes to buckle a torsion pass square boss torsion pass square.Because the effect of the gap of this connection compensation stage clip, between die nipple body and the slip female coupling tap cover is gapless, radial clearance and oscillating quantity, depend on the manufacturing play of slip female coupling tap cover and the ratio of slip female coupling tap cover and its external diameter, for reducing the harmful effect of play in transmission of slip female coupling tap cover, satisfy instructions for use, should use the less slip cooperating relationship in gap between slip female coupling tap cover and the chamber wall, the ratio of the female coupling tap that slides in addition cover length and its external diameter is big more, then transmission rigidity is good more, experimental results show that, its practical ratio is best at 1-1.1, and the stable bond of die nipple body, practical ratio should be best at 0.9-1.0 between die nipple body length and die nipple body outside diameter.Use near determining about the male and female cone from the non-self-locking cone face angle optimum value of the locking angle, proof will have the measured to the greatest extent rigidity of setting upright, again not self-locking by experiment, still can make things convenient for rotating operation bayonet socket and withdrawing, the optimum value of face angle 8 ° 30 '-9 ° 30 ' between.The such structure and the impact of performance of generation, it is low to have solved the efficient of then unloading that transmission rigidity is good generally in the prior art, otherwise the transmission rigidity that the efficient of unloading is high is then poor, perhaps bore and use quick-connect machanism as number of patent application 01203777X water, this three steel balls connect the transfer torque of holding concurrently fast because than precision and complex structure, meet mud in the construction, drilling cuttings, machine is assorted, the unities of contradictions such as unpractical weak point of the difficulty of
