Description

The invention relates to the mining industry and can be used in auger drilling and drilling machines for mining, as well as in drilling exploration, gas and gas wells. A locking joint is known, containing a cylindrical sleeve with a locking element mounted on the end of one screw; and a shank included in it with tabs of the other screw flj. In the process of operation, the main elements (for example, locking rocker arms, springs, rollers) are prone to gagging, which leads to their rapid release. In addition, the transfer of the required moment from one section to another requires the best strength of spring-loaded plates and other elements of the lock joint, this will lead to large dimensions of the latter due to its design features. A locking connection is known, comprising a cylindrical sleeve with a locking element mounted on the end of one screw, and a shank entering it with protrusions of another screw. The locking element is designed as two articulated two-shoulder arms and spring-loaded stops mounted inside the coupling, installed in adjustable plugs fixed in the coupling body, with one ends of the two shoulders interacting with the lugs of the shank, while others are made with bevels that interact. with heads of spring-loaded stops. The joint is equipped with a spacer that is full, for example, in the form of a flat swivel roller installed between the ends of the double-arm levers, made with bevels, the ends of which are passed through the holes beyond the mu (| yy J5 J) This connection is complicated and unreliable, because spring-loaded ynopfel, installed in traffic jams on the coupling housing, are subjected to sealing with a buried mass. To eliminate the self-adjustment of the traffic jams, the fixtures are insignificant, and the gap between the inner wall of the building that is insignificant by design conditions The couplings and double-arm levers prevent the latter from operating even if the mineral gets slightly inside the coupling.To destroy special minerals sticking in this area of the mineral particles, special devices are necessary, for example, toothed racks. The purpose of the invention is to simplify the design and improve the reliability of the connection. This is achieved by installing a plate spring between the two levers on the axis of their rotation, the ends of which are placed in grooves made on the inner surface of the ends chagov. FIG. 1 is a schematic diagram of a lock joint; in fig. 2 shows a plate spring; in fig. 3 Dan S1D along arrow A in FIG. 2. The locking connection contains a cylindrical coupling 1 mounted on the end of one section 2 and the shank 3 with protrusions 4 of the other section 5 entering it. 8, coupling 1, has a fixed element made in the form of two double-arm 7 symmetrically arranged on the axis 6 and symmetrically arranged and 8, some of which are equipped with cams 9 and 10 interacting with the protrusions 4. Between the double-arm levers 7 and 8 on the axis 6 there is a plate spring 11, the ends 12 and 13 of which are placed in the slots 14 and 15, made on the inner surface ends ry Agov cams 9 and 1O. To remove the cams 9 and 10 {and 1 of steps 7 and 8 from the contact with the projections 4 of the needles 3, a pusher 16 is provided with a cone 17. The pusher is moved using a remote drive (not shown). Coupling i is equipped with pins 18. and 19, which interact respectively with the sleeves 2O to 21 of the catcher 22. The locking connection works as follows, When performing the joining operation, the shank 3 of the section 5 is fed inside the coupling 1. At the same time, the bevels of the cams 9 and 1O the bevels of the projections 4 of the shank 3. The ends of the levers 7 and 8 rotate around the axis 6 and drop over the projections 4. The constant contact of the cams 9 and 10 with the projections 4 is provided by the action of the clamps 12 and 13 of the spring 11 on the levers 7 and 8. When performing the separation sections 2 and 5 with n By means of a remote drive, the pusher 16 is moved towards the levers 7 and B. The taper 17, interacting with the ends of the levers 7 and 8, rotates them around axis 6, as a result of which the cams 9 and 1O converge and release the protrusions 4. The disconnected section 5 moves (left) until the shank 3 leaves the clutch 1. The pusher 16 moves back (to the right), under the action of the ends 12 and 13 of the spring 11, the levers 7 and 8 rotate around the axis 6 and take the initial position for filling the coupling steps. Installing the leaf spring between the two shoulders on the axis of rotation will increase the reliable connections in operation and the drill stem and will also significantly simplify the design and speed up the process of separation and connection of sections. The most successful invention can be used in the drilling of large-diameter wells, where it is necessary to overcome large bonding forces at the points of contact of the protrusions of the shank and the cams of two shoulders. The locking element and km control units are located inside the clutch, therefore they will not be subject to lightning, which will increase their service life. Formula of the invention The locking connection containing a cylindrical sleeve mounted on the end of one section, and a shank included in it with protrusions of another section, fixing element made in the form of two-arm levers with cams, in order to simplify design and increase reliability in operation, between the two shoulders levers on the axis of their revenge is set a plate spring, the ends of which are placed in grooves made on the inner surface of the ends of the pins.
