Изобретение относитс к профилактике и ремонту бурильного оборудова- :ии и может быть использовано при восстановлении деталей замков бурильных труб, изнашиваемых по диаметру .The invention relates to the prevention and repair of drilling equipment: it can also be used in restoring parts of drill pipe locks worn in diameter.
Целью изобретени вл етс обеспечение многократности ремонта замка .The aim of the invention is to provide multiple repair of the lock.
На фиг.1 представлен изношенный замок бурильной трубы; на фиг.2 то же, после восстановлени .Figure 1 presents the worn lock drill pipe; Figure 2 is the same after recovery.
Изношенную в процессе бурени деталь 1 замка (муфту или ниппель) вместе с бурильной трубой 2 после достижени определенной нормы величины износа протачивают на величину наибольшего износа, захватьша полностью изношенный объем 3.A part 1 of the lock that is worn out during drilling (a sleeve or a nipple) together with a drill pipe 2, after reaching a certain rate of wear, is pierced by the amount of greatest wear, capturing a completely worn volume 3.
На полученную таким образом цилиндрическую поверхность 4 напрессовывают втулку, состо щую из двухOn the thus obtained cylindrical surface 4, a sleeve consisting of two

частей: втулки, армированной твердым сплавом 5 5 располагаемой на месте наибольшего износа, и второй втулки 6. Напрессованные втулкиparts: bushings, reinforced with a hard alloy 5 5 located at the place of greatest wear, and the second sleeve 6. The pressed bushings
5 закрепл ют на замке сварным пшом 7, который вьтолн ют по близлежащим друг к другу торцам втулки. Втулки могут быть изготовлены из износостойких материалов.5 is secured on the lock by a welded rod 7, which is threaded along the adjacent ends of the sleeve. Bushings can be made of wear-resistant materials.
О При необходимости последующего восстановлени при напрессовкв примен ют втулки, имеющие длину, отличную от втулок, прш1ен емых при пре- дьщущем ремонте, вследствие чего О If necessary, the subsequent restoration at press-ons use bushings having a length other than the sleeves made during the preceding repair, as a result of which
15 сварной шов каждый раз располагаетс на новом месте, что исключает пов торные приварки на одних и тех же местах тела замка. Благодар этому термическое вли ние сварки сводит20 с к минимуму и лишь незначительно вли ет на механические свойства тела замка.15 the weld seam is placed at a new location each time, which excludes secondary welding on the same parts of the lock body. Due to this, the thermal effect of welding minimizes 20 s and only slightly affects the mechanical properties of the lock body.
