Изобретение относитс к буровому инструменту, а именно, к соединению буровых штанг.FIELD OF THE INVENTION The invention relates to a drilling tool, namely to the coupling of a drill rod.
По основному авт. св. № 373390 известно устройство дл разгрузки резьбовых Соединений буровых штанг, содержащее разрезную кольцеобразную деталь, состо щую из нескольких сегментов и размещенную между торцами буровых штанг, соедин емых между собой при помощи резьбовых ниппел Kf муфты. Кольцеобразна деталь имеет конусные поверхности на обоих торцах. УГОЛ конусности торцевых поверхностей принимаетс с таким расчетом, чтобы при осевом нагружении возникала выталкивающа сила, стрем ща с раскрыть кольцеобразную деталь. В месте разъема кольцеобразна деталь ст нута болтом ll.According to the main author. St. No. 373390, a device for unloading threaded joints of drill rods is known, which contains a split ring-shaped part consisting of several segments and placed between the ends of the drill rods, interconnected by means of threaded nipples Kf of the coupling. The ring-shaped part has tapered surfaces at both ends. The angle of tapering of the end surfaces is taken so that under axial loading an ejection force occurs, tending to open the ring-shaped part. In place of the connector, the ring-shaped part of the string is bolt ll.
Недостаток известного устройства заключаетс в том, что разъединение концов штанг при существующих нагрузках от веса инструмента занимает много времени и требует трудоемких ручных операций.A disadvantage of the known device lies in the fact that the separation of the ends of the rods under the existing loads from the weight of the tool takes a lot of time and requires laborious manual operations.
Цель изобретени - упрс дение монуажа и демонтажа соединени буровых штанг..The purpose of the invention is to control the monoazha and dismantle the connection of the drill rods ..
Указанна цель достигаетс тем, что в устройстве ст гивающий элемент выполнен в виде подпружиненного стакана , установленного концентрично на наружной поверхности ниппел с возможностью взаимодействи с разрезной кольцеобразной деталью по ее наружной поверхности.This goal is achieved by the fact that in the device the tightening element is designed as a spring-loaded glass mounted concentrically on the outer surface of the nipple with the possibility of interaction with a split ring-shaped part along its outer surface.
На фиг. 1 изображено соединение, FIG. 1 shows the connection
0 общий ВИД; на фиг. 2 - йечение А-А на фиг. 1.0 overall appearance; in fig. 2 - treatment AA in FIG. one.
Устройств ДЛЯ разгрузки резьбовых соединений буровых штанг состоит из ниппел 1 и муфты 2, имеющих резьбу (например, коническую). На ниппеле укреплено неподвижно кольцо 3 и имеетс бурт 4. Концентрично на наружной поверхности ниппел подвижно укреплен отт гивающий элементDevices for unloading threaded joints of drill rods consists of nipple 1 and coupling 2 having a thread (for example, tapered). There is a fixed ring 3 on the nipple and there is a collar 4. Concentric on the outer surface of the nipple is a movably secured pull element.
стакана 5, к торцу которого прикреплена крьоака 6. Между кольцом 3 и крышкой 6 размещен упругий элемент 7 (пружина). Бурт ниппел имеет торцевую коническую поверхность Б, а торец муфты - зеркал, но отображенную коническую поверхность С, Образующие при соединении, муфты и ниппел конический паз. Угол наклона кониQ ческих поверхностей выбираетс наcup 5, to the end of which is attached to the cloac 6. Between the ring 3 and the cover 6 is placed an elastic element 7 (spring). The burt nipple has an end conical surface B, and the end of the coupling has mirrors, but the displayed conical surface C, which forms a conical groove at the connection, the couplings and nipple. The angle of inclination of the conical surfaces is chosen on
