Device consists of damper between lifter and generator of vertical pulses tied with string from below. The damper corresponds to a vertical pressure tight cylinder with a piston, internal cavity of which under the piston is filled with gas. The generator is made as a tubular case consisting of serially connected power cylinders; on top the tubular case is coupled with a rod of the damper piston. The cylinders are equipped with power pistons serially tied by means of hollow rods so, that their sub-piston cavities are inter-communicated and are communicated with a piston valveless pump via a distributor and a safety valve. A lower rod of the power piston is blinded from beneath and is connected with the string. The distributor consists of a cylinder case with two chambers divided with a partition. The safety valve is installed between the distributor and the piston valveless pump; it communicates this branch with a buffer reservoir. Between the lower rod of the hydro-cylinder and the string there is installed a T-branch connected with an additional pump with a reservoir, which communicates with annular space of the well. Over a point of freeze-in the string is equipped with a vibrator of radial action consisting of a hollow cylinder encasing a rod with pass channel and of a seat positioned in the pass channel of the rod; a ball is inserted in the seat. The cylinder is made eccentric, centre of gravity of which is set off relative to axis of the device.

FIELD: mining. SUBSTANCE: vibrator comprises body connected with upper and lower adapters, rod arranged in upper adapter casing and provided with flange-like hammer and cams to interact with upper adapter anvil and lower adapter cams, and ball cage arranged between anvil working elements and hammer working elements. Said anvil working elements and hammer working elements are composed by bearing cages articulated with upper adapter and rod flange. EFFECT: longer life, lower costs. 1 dwg
The invention relates to mining, namely, devices for retrieval from the well stuck pipe or rod. A device for stuck emergency pipe string, comprising a housing, a cavity which is placed over the spindle and located between the housing and the spindle drum site in the form of balls and a split resilient sleeve (see ed. the certificate of the USSR No. 1265282, CL EV 23/00, 1986). The disadvantages of this device should be attributed to the relatively rapid failure of his drum site, elements of which are subjected to increased wear on each shot. Another disadvantage is the need for high precision manufacturing elements of the percussion mechanism, leading to a rise in the cost of the device as a whole. The closest in technical essence and the achieved result is a vibrator, comprising a housing connected to the upper and lower adapters placed in the cavity of the upper adapter stem with drummer flange and Cams for engagement respectively with the upper anvil adapter and Cams the lower adapter and installed between work items anvil and striker of the ball cage (see ed. the certificate of the USSR No. 117796, CL EV 31/107, 1960). The disadvantage of this vibrator is small resource of its impact site, and PE is first of all its operational elements, made in the form of fixed rivets. This leads to rapid wear of the rivets and as a consequence reduce the effectiveness of the work as shock mechanisms, and the vibrators, and this is due to the appreciation of drilling operations and extending the period of exploration. In connection with the stated technical result of the invention is to increase the service life of the vibrator and as a consequence reducing the cost of drilling operations. This technical result is achieved by the fact that in the vibrator, comprising a housing connected to the upper and lower adapters placed in the body cavity of the stem with drummer flange and Cams for engagement respectively with the upper anvil adapter and Cams the lower adapter and installed between work items anvil and striker ball holder according to the invention the working elements of the anvil and striker made in the form of clips with bearings, Rethimno connected to the upper adapter and the flange of the stem. The invention is illustrated by the drawing, which shows a General view of the vibrator in the longitudinal section in the working position. The proposed vibrator includes a housing 1, which is connected with the upper and lower adapters 3 and 4 and placed in the cavity of the housing 1, the shaft 2. The upper adapter 3 and the shaft 2 is equipped with the COO is responsible anvil 9 and drummer 6, made in the form of a flange. The anvil 9 and the striker 6 is made of wear-resistant material and equipped with work items 7 and 8 in the form of clips with bearings, Rethimno connected respectively with the upper adapter 3 and the flange 6 of the rod 2. Between work items 7 and 8 are placed with the opportunity to interact with them in the working position of the ball holder 5. The upper end of the lower adapter 4 and the lower end of the flange 6 is equipped with Cams 10 and 11, interacting in the lowest position of the piston rod 2, and serve to transmit torque to the fishing tool (not shown). For sealing the vibrator is provided by seals 12, fixed in the circular bores of the upper and lower adapters 3 and 4. The principle of operation of the vibrator is as follows. Together with the fishing tool on a drill string vibrator down into the well to contact the emergency column. In this case, the shaft 2 of the vibrator goes down and slow turning his jaws 10 are in engagement with the Cams 11 of the lower adapter 4. Then, without lifting a drill string, it rotates the rotor of the drilling machine and connect the fishing tool with the emergency column. Convinced of the reliability of the connection, the entire projectile lift slightly upwards, so that the Cams 10 disengage from the Cams 11 and Shari the new ferrule 5 is in contact with the working elements 7 and 8. Next, pull the string of drill pipe and begin to rotate. When this ball holder 5 is rolled over the roller bearings 7 and 8, creating a vibrational load due to vertical movement of the ball cage relative to the working elements 7 and 8. During this stroke the ball cage 5 can be adjusted by changing the distance between work items 7 and 8 or by changing the height of the rim of the pellet holder 5. In the proposed vibrator due to the quality of work items incorporating ball or roller bearings 7 and 8 exclude their one-sided wear that takes place in the prototype. And one-sided wear significantly reduces the service life of the working elements 7 and 8, which is of special importance in severe accidents associated with sticking disaster columns. In this case, the liquidation of accidents is greatly increased and the effective operation of the vibrator will significantly reduce the overhead of time in an emergency. The removable connection of the working elements 7 and 8 with the top adapter 3 and the flange 6 also allows you to reuse all of the elements of the vibrator except wear items: ball cage 5 and the working elements 7 and 8. In General, this will increase the life of the vibrator and as a consequence to reduce the cost of carrying out n the productive operations. Vibrator, comprising a housing connected to the upper and lower adapters placed in the cavity of the upper adapter stem with drummer flange and Cams for engagement respectively with the upper anvil adapter and Cams the lower adapter and installed between work items anvil and striker of the ball holder, characterized in that the working elements of the anvil and striker made in the form of clips with bearings, Rethimno connected to the upper adapter and the flange of the rod.
