(54) МАГАЗИН ДЛЯ БУРОВЫХ ШТАНГ(54) DRILLING ROD SHOP

1one

Изобретение относитс к буровой технике , а именно к устройствам дл хранени и выдачи буровых штанг в процессе бурени и приема штанг обратно в магазин при извлечении бурового става из скважин.The invention relates to a drilling technique, namely, devices for storing and dispensing drill rods during the drilling process and receiving the rods back to the magazine when retrieving a drill rod from wells.

Известен магазин дл буровых штанг, содержащий корпус барабанного типа, в котором штанги располагаютс на цилиндрической поверхности в захватах штанговедущих звездочек 1.A drill rod shop is known, comprising a drum-type casing in which the rods are located on a cylindrical surface in the grippers of rod-leading sprockets 1.

Однако дл выдачи штанг из магазина и приема их обратно в магазин осуществл ютс последовательные повороты штангОведуших звездочек на шаг размещени штанг, что ведет к значительному увеличению габаритов устройства при возрастании количества укладываемых штанг, начина с 15- 20 штанг.However, successive rotations of the rods of Lead Stars to the placement of rods are carried out to release the rods from the magazine and receive them back into the magazine, which leads to a significant increase in the size of the device as the number of rods increases, starting from 15 to 20 rods.

Известен также магазин дл буровых штанг, содержащий цилиндрический корпус , поворотный вал со штанговедущими звездочками и приводом поворота, включающим гидроцилиндр и св занный с ним рычагом храповой механизм 2.A drill rod shop is also known, comprising a cylindrical body, a rotary shaft with rod-bearing sprockets and a turn actuator comprising a hydraulic cylinder and a ratchet mechanism 2 associated with it.

Недостатком этого устройства вл етс его низка надежность, так как в процессе захвата штанг из наружного р да npxjИСХОДИТ выпадение штанг из внутреннего р да.A disadvantage of this device is its low reliability, since in the process of picking up the rods from the outer row, npxjOUND, the rods fall out of the inner row.

Цель изобретени - повышение надежности работы устройства при многор дном размещении штанг за счет предотвращени выпадений штанг из внутренних р дов до полной выдачи штанг из наружных р дов.The purpose of the invention is to increase the reliability of the device during the multilateral placement of the rods by preventing the rods from falling out of the inner rows until the rods are completely released from the outer rows.

Поставленна цель достигаетс тем, что магазин снабжен дополнительными, установленными на поворотном валу с возможностью осевого перемещени штанговедущими звездочками, ступицы которых выполнены в виде, ступенчатых стаканов, охватывающих с внешней стороны и с торцов штанги соседнего внутреннего р да, а рычаг выполнен с фиксирующими элементами, количество которых соответствует количеству р дов щтанг.The goal is achieved by the fact that the magazine is equipped with additional axle-mounted sprockets mounted on the rotary shaft with axial movement, the hubs of which are made in the form of stepped glasses covering from the outside and from the ends of the rod of the adjacent inner row, and the lever is made with locking elements, the number of which corresponds to the number of rows shtang.

На фиг. 1 представлено устройство, продольный разрез; на фиг. 2 - вид А на фиг. 1; на фиг. 3 - штанговедуща звездочка , разрез в увеличенном масштабе.FIG. 1 shows the device, a longitudinal section; in fig. 2 is a view A of FIG. one; in fig. 3 - shtanoveduschaya sprocket, a section on an enlarged scale.

Claims

The magazine consists of a cylindrical body 1 with end caps 2 and 3, a rotary shaft 4, at the ends of which, with key joints, there are 5-10 sprocket wheels mounted. Moreover, the internal (small) sprockets 7 and 8 are rigidly mounted on the shaft, and the rest are axially displaceable along the shaft 4 and fixed on the shaft in the desired position using spring-loaded latches 11. There are drill straps 12 in the grips of driving sprockets. In the cylindrical body 1 There is a window 13 for dispensing and receiving rods. The drive rotation of the shaft 4 consists of a hydraulic cylinder 14, pivotally connected to the cover 2 and the lever 15, mounted on the housing 16 of the ratchet mechanism. The ratchet wheel 17 on the key is seated at the end of the shaft 4, and the spring-loaded dog 18 is mounted on an axis in the housing 16 of the ratchet mechanism. Since the central angle between the axes of the adjacent rods (the pitch of the sprocket-like sprockets is approximately the same in all rows) increases from the outer rows to the inner rows, holes 15-2 are provided in the lever 15 at different distances from the shaft axis 4. The number of holes corresponds to the number Dov rod bars in the store. At the same stroke of the rod of the hydraulic cylinder 14, depending on the point of its connection with the lever 15, the angle of rotation of the pinnacles corresponds to the angle of installation of the rods in a certain row. The outer weight-bearing sprockets are made in the form of a sleeve 22 rigidly connected to the disk 23, which has a stepped rim 24. The disk 23 with the rim 24 form a chamber for the rod 12. The magazine operates as follows. After installing the magazine on the frame of the drilling rig or in the m & manipulator (not shown), it is inserted inside the cylindrical housing 1 through the window 13, seizes the outer row strut opposite the window, and, removing it through the window 13, feeds the drilling axis . Then, the hydraulic cylinder 14, which acts on the lever 15, the ratchet body 16 and the pawl 18, is put into operation, turns the ratchet wheel 17 with the shaft 4 and the rod-bearing sprockets to the step of installing the rods in this row. The next rod is brought to window 13. During the return stroke of the hydraulic cylinder rod, the spring-loaded pawl 18 slides along the teeth of the ratchet wheel 17 without rotating it. After issuing the last rod, the external sprockets 5 and 10 manually or with a special hydraulic cylinder (not shown) are retracted to the sides and mounted on spring-loaded latches 25. The hydraulic cylinder rod 14 is connected by a locking element 26 to the lever 15. The magazine is operated in that the same sequence as before, in the manipulator, seizes the bars of the next row. After issuing all the rods from the second row, the sprockets 6 and 9 are retracted to the side (shown by dotted lines), and the cylinder of the hydraulic cylinder is connected to the hole 21 of the lever 15. The magazine when receiving shtangs is carried out in the reverse order. First, the rods are placed in the inner row onto the claws of the sprockets 7 and 8. Then the sprockets 6 and 9 are moved, the hydraulic cylinder rod is mounted on the next hole and the rods are placed in the next row. Formula of the invention The drill rod shop, containing a cylindrical body, a turning shaft with shtamped sprockets and a rotational drive including a hydraulic cylinder and a ratchet mechanism associated with it, characterized in that, in order to increase the reliability of operation of the device during multi-way placement of shtangs, After falling out of internal rows, before full issuance of external rings, it is equipped with additional axle-mounted sprockets mounted on the rotary shaft with axial movement, the hubs of which are made in the form of stepped glasses covering from the outside and from the ends of the rod of the adjacent internal yes, and the lever is made with locking elements, the number of which corresponds to the number of rows of rods.
