(54) БУРОВАЯ МАЧТА(54) DRILLING MAST

.Изобретение относитс к буровой технике, а именно к буровын мачтам дл использовани в механизированных и.автоматизированных буровых установках.The invention relates to drilling machinery, in particular to drilling masts for use in mechanized and automated drilling rigs.

Известна бурова мачта, содержаща ногис установленными на них фермами , на которых крепитс свечеподающее устройство Г1.The boring mast is known, which has legs with trusses mounted on them, on which the candle-feeding device G1 is attached.

Недостатком данной мачтн вл етс то, что при монтаже и демонтаже свечеподающего устройства требуютс верхолазные работа. The disadvantage of this mast is that the installation and disassembly of the candle-feeding device requires steeplejack work.

Наиболее близкой к предлагаемой по технической сущности и достигаемому результату вл етс . 6yj3OBa мачта , содержсцца ноГи с кронштейнами стрелами дл свечеподающего устройства . Closest to the proposed technical essence and the achieved result is. 6yj3OBa mast, supporting arms with brackets for the candle-feeding device.

При применении данной мачты исключены , верхолазные работы при монтаже и демонтаже свечеподающего устройства t23.When using this mast excluded, climbing works during installation and dismantling of the t23 candle-feeding device.

Однако данна мачта требует применени сложных верхолазных работ и значительной затраты времени при изменении положени кронштейнов. Эти работы необходимо проводить на высоте более 20 м от шарниров ног мачты , вышкомонтажной бригадой, перемещениеHowever, this mast requires the use of complex climbing activities and a considerable amount of time when changing the position of the brackets. These works should be carried out at a height of more than 20 m from the hinges of the legs of the mast, the crew of the assembly team, moving

кронштейнов провод т в процессе бурени скважины при -изменении длины свечи бурильных труб, которое влечет за собой изменение положени свечеподающего устройства св аант ного с кронштейнами.The brackets are carried out while drilling the well with a change in the length of the plug of the drill pipe, which entails a change in the position of the plug-in device attached to the brackets.

Целью изобретени вл етс снижение затрат времени и трудоемкости монтажных работ при изменении высоты The aim of the invention is to reduce the time and complexity of installation work when changing the height

10 подвеса свечеподающего устройства.10 suspension candle suppressor device.

Эта цель достигаетс тем, что мачта снабжена т го1й переменной длины , соединенной с ногой, при этом один конец крон11тейна-стрелы шарнир15 но закреплен на ноге, а другой иар .нирно с т гой.This goal is achieved by the fact that the mast is equipped with a variable length that is connected to the leg, with one end of the crown boom being hinged on the leg, and the other end fittingly with the leg.

На фиг. 1 представлена схема креплени кронштейнов-стрел к ногам буровой мачты; на фиг. 2 - расположе20 ние кронштейнов-стрел в плане; на фиг. 3 - сечение А-А па фиг. 1. .FIG. 1 is a diagram of the attachment of the bracket arms to the legs of the drilling mast; in fig. 2 - arrangement of brackets-arrows in the plan; in fig. 3 is a section AA of FIG. one. .

Бурова мачта содержит ноги 1, кронштейны-стрелы 2 с подвесами 3 дл креплени свечеподающего устрой25 ства 4 .The drill mast contains legs 1, arms-arrows 2 with suspensions 3 for fastening a candle-feeding device 4.

Ноги 1 соединены между собой балгкой 5i на которой установлены с возможностью поворота кронштейны-стрелы 2, посредством проушин б и осей / The legs 1 are interconnected by a balck 5i on which the boom arms 2 are installed with the possibility of rotation, by means of eyelets b and axes /

Claims

30 7. In the front part of the boom arms 2, screw rods 8 are hingedly attached, which with the aid of nuts 9 and supports 10 are connected to the projections 11 of the front faces of the legs 1 of the mast buckle. Arrows-booms 2 have the ability to rotate around plane 7, for example, turning at an angle of (limits i ЗР allows candle-supporting device 4 to move with a height of ± 1 m, which at the present time determines the tolerance limit for pipe lengths The arms-booms 2 are connected between each other by a cross beam 12, on which the rollers (blocks) 13 of the lifting equipment are installed, to prevent the front arms of the brackets from moving. The arms 2 are mounted on the legs of the 1 drill tower 14. 2 are laid on the mast. To the eyes 6, beams 5 on the axis x 7 are suspended by brackets 2 with suspensions 3 and screw rods .8. Then, the wires 8 are fastened to the supports 10 on the projections 11 legs 1 of the drill Mast arms. Arrows 2 are connected to each other by means of a cross member 12 carrying rollers 13. Brackets 14 are fixed on legs 13. Brackets 14 are attached on legs 1 and connected, with bracket arms 2.. after mounting the brackets on arrows 2 they are supplied with a wire sink device 4 and attached to the suspensions 3, after which the mast is raised. The device is ready for operation. If it is necessary to move to a new length of spark plugs in drill pipes, the work on moving the power supply device 4 is carried out in the following order. Through the rollers 13 mounted on the cross bar 22, the crown brackets 2 are connected to a lifting device, for example, a Talev block, an auxiliary winch, etc. (connection not shown) and transfer the load from the weight of the candle-giving device 4 to the lifting device after which the nuts 9 of the screw rods 8 and the attachment of the brackets -14 are loosened and the front part of the boom-brackets 2 with is carried out. Candidate the device to the mark corresponding to the new length of the drill pipe candles. A new position is fixed by tightening the nuts 9 of the screw tons 8 and fixing the brackets 14 on the legs of the 1 drilling mast. The process of mechanization and automation of tripping operations in drilling imposes more stringent requirements on the length of spark plugs of drill pipes, which makes it necessary to move the candle-feeding device up or down. This is achieved by turning the front ends of the boom arms with a jacketed device relative to the rear axle. The use of the proposed mouth-. In comparison with the known, the properties will provide: -reduction of the lifting time of the feeding of the candle-feeding device, approximately 2 times; - reduction in the number of workers; on these jobs and the possibility of them being carried out by the forces of the drilling crew; -expansion of the range of lengths of drill pipes in the selection of candles. The invention of the Drill Tower containing legs with arms-brackets for the Candlestick device, so that in order to reduce the time and complexity of the installation work when the height of the suspension device is changed, it is equipped with a variable length, connected to the leg, with one end of the bracket-boom pivotally attached to the leg, and the other end pivotally connected to the rod.
