(5) УСТРОЙСТВО дл СПУСКО-ПОДЬЕМНЫХ ОПЕРАЦИЙ в СКВАЖИНЕ(5) DEVICE FOR CUTTING AND RISING OPERATIONS IN THE WELL

1one

изобретение относитсй к буреникг скважин, а именно к устройствам дл спуско-подъемных операций в скважине.The invention relates to drilling wells, namely to devices for tripping in a well.

Известно устройство дл спускоподъемных операций в скважине, содержащее кронблок, механизм захвата и перемещени труб и центратор f1 J,A device for tripping in a well is known, comprising a crown block, a mechanism for gripping and moving pipes and a centralizer f1 J,

Недостатками данного устройства вл ютс сложность конструкции и невозможность использовани при работе с трубами разной длины, что снижает область применени устройства.The disadvantages of this device are the complexity of the design and the inability to use when working with pipes of different lengths, which reduces the scope of application of the device.

Наиболее близким техническим решением из известных вл етс устройство дл спуско-подъемных операций в скважине, включающее кронблок, механизм захвата и перемещени труб и центратор, состо щий из поршн с центральным отверстием, подпружиненных центрирующих элементов и роли-ков z.The closest technical solution known is a device for hoisting operations in a well, including a crown block, a mechanism for gripping and moving pipes, and a centralizer consisting of a piston with a central bore, spring-loaded centering elements, and roller z.

Недостатком указанного устройства вл етс то, что его нельз использовать на передвижных установках, а также сложность конструкции, в результате чего снижаетс скорость проведени спуско-подъемных операций и тем самым снижаетс производительность труда.The disadvantage of this device is that it cannot be used on mobile units, as well as the complexity of the design, as a result of which the speed of the lifting and lowering operations is reduced and thus labor productivity decreases.

Цель изобретени - повышение производительности устройства за счет механизации управлени центратором.The purpose of the invention is to increase the productivity of the device by mechanizing the control of the centralizer.

Указанна цель достигаетс тем, что устройство снабжено двуплечим рычагом, шарнирно соединенным с кронблоком и св занным т гами с механизмом захвата и перемещени труб и 5 центратором, причем последний имеет установленный на корпусе центратора с возможностью поворота вокруг своей оси управл ющий ралик с рычагами, а центрирующие элементы св заны с валиком с помощью т г.This goal is achieved by the fact that the device is equipped with a two-arm lever pivotally connected to the crown block and connected to the mechanism for gripping and moving pipes and 5 by a centralizer, the latter having a control lever with levers mounted on its centralizer body centering elements are connected to the roller with the help of t.

Claims

FIG. 1 shows the general scheme of the device; in fig. 2 - centralizer; in fig. 3, node t in FIG. one; in fig. k double shoulders lever, general view. The device consists of a mechanism for capturing and moving pipes 1, a crown block 2 and a centralizer 3. The hub 3 consists of a body C having a centrally located opening with a cutout and spring-loaded centering elements 5 mounted on it. 7. The spring-loaded centering elements 5 are rotatably mounted and connected, by means of t, g 8, to a roller 9 / which passes into the lever 10 perpendicular to the roller, having a hole in which e enters tg 11, securing to the spring-loaded stop 12 located under the crank, the other end of the rod 11 is fastened to the lever 13, which is rotatably mounted around its axis Ik, under the spring-loaded two-arm, and to the other arm of the lever 13 fastened by flexible ha 15 with a mechanism for gripping and moving pipes. The device works as follows. In the process of lifting, the turned-off pipe located in the casing k of the centralizer 3, the upper worker captures with the capture mechanism 1. The arm of the lever .13 on which the gripping mechanism 1 hangs on the flexible 15, the weight of the pipe goes down until it stops, and the other arm of this lever 13 rises up and doesn’t pull the 11 with the support .12, which lifts the lever 10, while the roller 9 is rotated, and the rods 8, acting on the spring-loaded centering elements 5, retract them inside, the centralizer 3 opens, and the gripping mechanism 1 leads the pipe out of the centralizer 3 and installs it in the 9th flange. The weight of the pipe ceases to act on the lever 13, it returns to its original position under the action of a spring. The motor 11 with an anvil 12 is lowered, the interaction with the lever 10 is interrupted. The lowering of the lever 10 occurs due to the elastic spring force that is transmitted to the roller 9 through the tractor 8, the centralizer 3 is closed; Due to the mechanization of the control of the centralizer, the process of carrying out tripping operations is accelerated and thus labor productivity is increased. The invention is a device for tripping a borehole, including a crown block, a mechanism for gripping and moving pipes, and a centralizer consisting of a body with a central hole, spring-loaded centering elements and rollers, which, in order to improve the performance of the device due to mechanization of the centralizer control, it is equipped with a two-arm lever pivotally connected to the crown block and connected with the gripping and moving mechanism of the pipes and the centralizer, the latter having The centering pushes the control roller with levers with the possibility of rotation around its axis, and the centering elements are connected to the roller with the help of t.
