The lower part of the carriage is equipped with a latch 21 in the form of a hydraulic cylinder with rods 22 and 23, sockets 24 in the disk 8 under the rod 22 and the socket 25 in the base under the rod 23. To the right of the drum ^{50 is} a tray 26 for transmitting pipes to a manipulator (not shown) when they are unloaded from the drum.

Устройство может быть размещено ⁵⁵на автомобильном полуприцепе или самоходной тракторной базе (не пока-₍заны) .The device can be placed ⁵⁵ on a car semitrailer or self-propelled tractor base (not shown ₍ not shown).

Предлагаемое устройство работает следующим образом.The proposed device operates as follows.

При загрузке устройства (подъем бурового снаряда) каретки 6 переводят в верхнее положение (фиг. 2). Для. этого шток , 22 фиксатора 21 вводят в гнездо 24 диска 8 барабана, а шток 23 выводят из гнезда 25 основания , Барабан 2 поворачивают приводом Зв положение загрузки. Вместе с ним перемещают каретки 6. После остановки барабана шток 22 фиксатора 21 выводят из гнезда 24 диска 8, а шток 23 вводят в гнездо 25 основания. Очередную трубу 13 подают манипулятором (не показан) на приемный элемент 19, с которого она скатывается в гнездо 17 диска 16, Затем гидроцилиндром 18 поворачивают диск 16 против часовой стрелки и труба 13 скатывается в трубоприемный ручей 9 барабана. Когда ручей заполнен, выключатель или счетчик труб (не показан) дает сигнал о заполнении ручья и на поворот барабана на шаг трубоприемных ручьев. При повороте барабана рычаг 10 скосом 20 каретки поворачивается и запирает ручей. Далее ведут заполнение следующего ручья. При выгрузке магазина (спуске бурового снаряда) каретки 6 переводят в нижнее положение (фиг. 3). Подачу трубы из трубоприемного ручья на лоток 2бдля захвата манипулятором (не показан) производят поворотом диска 16 гидроцилиндром 18 по часовой стрелке.When loading the device (lifting the drill), the carriage 6 is moved to the upper position (Fig. 2). For. of this rod 22 of the latch 21 is inserted into the socket 24 of the drum 8 of the drum, and the rod 23 is removed from the socket 25 of the base, the drum 2 is turned by the drive Sv to the loading position. Together with him, the carriage 6. After stopping the drum, the rod 22 of the latch 21 is removed from the slot 24 of the disk 8, and the rod 23 is inserted into the socket 25 of the base. The next pipe 13 is fed by a manipulator (not shown) to the receiving element 19, from which it rolls into the socket 17 of the disk 16, Then the disk 16 is rotated by the disk 16 counterclockwise and the pipe 13 rolls into the pipe receiving stream 9 of the drum. When the stream is full, a switch or a pipe counter (not shown) gives a signal that the stream is full and the drum rotates by a step of the pipe receiving streams. When the drum is rotated, the lever 10 with the bevel 20 of the carriage rotates and locks the stream. Next, the next creek is filled. When unloading the store (lowering the drill), the carriage 6 is moved to the lower position (Fig. 3). The pipe is supplied from the pipe receiving stream to the tray 2b for capture by a manipulator (not shown) by turning the disk 16 by the hydraulic cylinder 18 clockwise.

При освобождении трубоприемного ручья выключатель или счетчик свечей (не показан) дает сигнал для поворота барабана против часовой стрелки на шаг между трубоприемными ручьями.When the pipe receiving stream is released, a switch or a candle counter (not shown) gives a signal for turning the drum counterclockwise by a step between the pipe receiving streams.

Таким образом, в предлагаемом устройстве перемещение трубы от манипулятора до ручьев магазина относительно незначительно, а осуществление заполнения и разгрузки ручьев происходит путем скатывания труб. Все это и обусловило упрощение конструкции устройства и обеспечило ускорение работы.Thus, in the proposed device, the movement of the pipe from the manipulator to the store’s streams is relatively insignificant, and the filling and unloading of the streams is carried out by rolling the pipes. All this led to a simplification of the design of the device and provided acceleration of work.

Наибольший эффект от применения предлагаемого устройства может быть достигнут при бурении глубоких геолого-разведочных скважин в условиях, когда мобильность оборудования играет исключительную роль, а затраты времени на спуско-подъемные операции наиболее значительны.The greatest effect of the application of the proposed device can be achieved when drilling deep exploration wells in conditions where the mobility of the equipment plays an exceptional role, and the time spent on tripping and hoisting operations is most significant.

Claims

3E having valves and pipe feeding mechanism 2. A disadvantage of this device is the complexity of the design and the impossibility of the constant movement of the pipes. The purpose of the invention is to simplify the construction and ensure the possibility of a constant amount of pipe movement. The goal is achieved by the fact that the pipe feeding mechanism is made in the form of at least two curvilinear guides mounted concentrically to the drum on the base and the carriages with pivot jacks placed under them wherein each carriage has a lock for alternately connecting with the drum and base. FIG. 1 shows a device D for storing and transporting pipes; in fig. 2 - relative position of the magazine and the feed mechanism during loading (lifting of the drill string); in FIG. the same, when unloading (the descent of the drill string, yes). The device comprises a base 1, a drum 2, a drum drive 3 mounted on a base 3 with a coupling coupling k, guides 5 with carriages 6, also mounted on the base 1 around the drum 2, fixed on each side of the drum 2 limiting disks 7 and fixed on the drum under guides 5 are two discs 8 with tube-receiving trenches 9 equipped with gates in the form of pivot levers 10 with limiting springs 11. In trenches 9 are placed 12 and 13. Carriages 6 on guides 5 are mounted on rollers Ik. The upper part of each carriage 6 is made in the form of a disk 1b mounted on an axis 15 with sockets 17 for a pipe, a hydraulic cylinder 18 connected to it and a receiving element 19 with a bevel 20. The lower part of the carriage is provided with a lock 21 in the form of a hydraulic cylinder with rods 22 and 23, a 2k socket The disk 8 for the rod 22 and the sockets 25 at the base for the rod 23. To the right of the drum, a tray 26 is installed, designed to transfer the pipes to a manipulator (not shown) when they are unloaded from the drum. The device can be placed on an automobile semi-trailer or self-propelled tractor base (not shown). The proposed device works as follows. When the device is loaded (lifting the drill bit), the carriage 6 is moved to the upper position (FIG. 2). For of this, the stem 22 of the retainer 21 is inserted into the slot 2k of the disk 8 of the drum, and the stem 23 is withdrawn from the socket 25 of the base. The drum 2 is turned by the actuator 3 to the loading position. Together with it, the carriages 6 are moved. After the drum has stopped, the rod 22 of the retainer 21 is withdrawn from the socket 2k of the disk 8, and the rod 23 is inserted into the socket 25 of the base. The next pipe 13 is fed with a manipulator (not shown) to the receiving element 19, from which it rolls into the slot 17 of the disk 16. Then the hydraulic cylinder 18 rotates the disk 16 counterclockwise and the pipe 13 rolls into the drum receiving creek 9 of the drum. When the stream is full, a switch or a pipe counter (not shown) gives a signal that the stream is filled and the drum is rotated by the step of receiving pipes. When the drum is rotated, the lever 10 by the bevel 20 of the carriage turns and locks the stream. Next are filling the next stream. When the magazine is unloaded (the drill is lowered), the carriage 6 is moved to the lower position (FIG. 3). The pipe from the stream-receiving stream is fed to the tray 2bl of the grip by means of a manipulator (not shown) by turning the disk 16 by means of a hydraulic cylinder 18 clockwise. With the release of the pipe stream, a switch or a candle counter (not shown) gives a signal to rotate the drum counterclockwise by a step between the pipe streams. Thus, in the proposed device, the movement of the pipe from the manipulator to the store streams is relatively insignificant, and the implementation of filling and unloading the streams occurs by rolling the pipes. All this led to a simplified design of the device and ensured the acceleration of work. The greatest effect from the application of the proposed device can be achieved with the drilling of deep geological exploration wells in conditions where the mobility of equipment plays an exceptional role and the time spent on tripping is most significant. Claims The device for storing and transporting pipes during lowering-lifting operations contains a horizontal rotary drum magazine installed on the base with pipe receiving slots having gates and a pipe feeding mechanism, characterized in that, in order to simplify the design and ensure constant the magnitude of the movement of the pipes, the feed mechanism is made in the form of at least two curvilinear by 9% 1. 6 controllers mounted concentrically to the drum on the basis of carriages with rotary sockets arranged under them for a pipe, each carriage having a lock for alternately connecting with the drum and the base.
