Description

store in the form of combs, on a candlestick with side stops, where the lower candles are mounted on a compact candlestick by the upper mechanism for moving pipes between the borehole axis and the sections of the store due to its greater run-up by rolling the candles of each subsequent row and the horizontal component of the candle weight.

The disadvantage of this installation is that it does not provide for the compact installation of candles required for a mobile unit.

Closest to the proposed ASP-3 system, installed on stationary towers, including the console section of the store in the form of combs installed in the tower, candlesticks with restrictions, fenced off by stationary barriers with wings on the sections and corridors, in width equal to the diameter of the largest dimension of the plug of the drill plug, as well as the mechanism for moving the pipes between the axis of the well and the sections of the magazine.

However, the known system is not designed for a wide range of pipes, and when candles are installed in it, a large windage is created, takes up a lot of space and has a lot of weight, which is why it is not acceptable for hanging on a mobile unit.

The purpose of the invention is to expand the scope of use by ensuring the installation of pipes of different diameters and increasing their stability in the shop sections.

This goal is achieved by the fact that, in a device for vertical placement of pipes in drilling or production towers, sections of the magazine are mounted on brackets with the possibility of fixed rotation in a plane perpendicular to the longitudinal axes of the fingers of the dies, while the fingers of the dies are installed with the possibility of rotation and fixation around their axes and have a parallelogram shape in cross section, and the orientation mechanism of the lower ends of the pipes is made in the form of a lever rigidly connected with a stand mounted on a horizontal axis in the plane of symmetry of the sections of the shop and the candlestick, with the possibility of discrete rotation under the action of the drive, made in the form of a cable-loading mechanism and a worm gear, and the cable-cargo mechanism is arranged with the possibility of rearrangement to fill or another part of the candlestick.

Thus, regulation of the width of the magazine section is provided depending on the diameter of the installed candles.

(pipes), and when installing the candlesticks on the candlestick (left and right parts), the bottom moves along the flap and horizontal lever that guides the candle to the place of its installation in the row, after filling which the lever is turned to fill the second row, etc. ., and after filling the right side, the left one.

Figure 1 shows the installation on a mobile unit, a general view; Fig. 2 is a view along arrow A in Fig. 1 (a magazine for pipe installation); on fig.Z - section bb in figure 1 (centralizer); Fig. 4 is a view along arrow B in Fig. 2 (rotary sections of the magazine for mounting the top of the pipes); figure 5 is the same, top view; figure 6 - podpubnik, side view; 7 - the same, top view; in Fig.8 is a view along arrow G in Fig.6; figure 9 - pipe grip, side view; in fig. 10 - the same, top view; figure 11 is a cross-section dD in figure 9; on Fig - filled sections of the store; in fig. 13-22 - the sequence of the technological process of installing pipes in the store section and on the candlestick.

The device contains divided rods with mini-fingers of the magazine for the top of the pipes right 1 and left 2 sections, tower 3, hanging block 4, stop 5, trolley 6, monorail 7 of the trolley 6, rope 8 folding stores, pipe elevator 9, guide cable 10 trolleys 6, handle 11 controls coil winch 19, fixture 13 for installing lower pipes, pipe spider 14, hauling ropes 15, hydraulic rotating (transfer) lever 16 with three degrees of freedom of movement for installing pipes, forked pulley block 17, centralizer 18 for pipes, wrench 19 for screwing-down pipe and pipe gripping 20.

Sections of shops (Figures 4 and 5) with fingers 21 are attached to their supports 22 by means of hinges 23, axis 24 is parallel to the slot of 25 fingers, installation of similar hinges is also possible between the fingers of sections (not shown). To store the hinge (axis 26 in the support 27) attached screw 28, the other end of which is passed through the support 29.

When screwing the nut 30 onto the screw 28, the latter has the ability to rotate the frame at an angle a from position 1 to position 2. Thus, the distance between fingers from A to B changes from larger to smaller and in the section into which large pipes are installed It is possible to install smaller pipes.

The maximum angle of the max turning of the magazine is determined by the smallest and Omin by the largest dimensions of the diameters of the pipes installed in it.

If there are hinges, you can also install multi-dimensional columns 2, 21/2, 3, and 4 tubing pipes between the fingers of each section. To do this, you need to turn the sections of the shops as well as individual fingers inside the template there are four angles a4, a3 -Gr2l / 211 and a211 corresponding to the specified tubing diameters.

To strengthen the fingers from horizontal forces, it is possible to have a hinge (D, E, F, 3 axis of the hinges), connecting to each section at least one more section (shown by dash-dotted lines), and in the right quadrilateral formed by the ZHD and ZHD (Fig. 12 ), and it is also possible to install the hinge in a pair of finger sections connected in pairs (upper and lower) to each other.

Candlestick design

A horizontal lever 32 with an axis 33 on the bearings is fixed on the candlestick in a plane passing through the center of the well and the candlestick on the posts 31, which is fixed by a nut with the help of the ratchet device 34 through the worm gear 35 (other means of fastening and turning are also possible). with the help of a self-brake, a pair of worms to-the-worm wheel).

On one side of the horizontal lever 32, a horizontal horizontal bar a is provided, parallel to the axis of rotation of the lever extending the stop b, on the other hand, a counterweight 36 is installed. On both sides of the floor 37 of the candlestick there are lateral stops 38 parallel to the axis of rotation and the horizontal bar. On axis 33, at an angle a, there are two axes 39, on which alternately, depending on how half of the candlestick is filled, a sash 41 is installed with a cable-cargo drive 40.

Pipe grip 20 consists of a body 42, pivotally suspended (axis 43 of rotation) to the bracket 44 of the lever 16 rotation, and buildings

45 and 46. The inner diameter of the housings 45 and

46 has a slot, the size of which is larger than the body of the pipe 47, but smaller than the body of the coupling 48. Thus, the coupling, hitting the housing 45 and 46, can no longer jump sideways. A cone-shaped funnel 49 is provided on the side of the housing 45 for ease of dispensing.

walking the pipe into the body of the pipe grip. Three rollers 50 are located underneath the housing 46 on the right side, along which the end of the coupling 48 of the pipe 47 is rolled during screwing-unscrewing (on the left side, the coupling 48 with the side surface rolls along the inner surface of the housing 45). To prevent the pipe from falling out of the pipe grip at the time of screwing-in or unscrewing or installing the pipes on the candlestick, mechanical locking of the pipe grip may be provided.

The installation of the pipes is carried out as follows. Initially, the device is installed in the extreme position A. To do this, it is necessary to unravel the ratchet by the handle of the screw pair, turn the lever 32 and lock it again. At the same time, the transfer lever 16 moves the candle from the center of the well (position I) to the flap 41 (position II), moves the flap 41 away, then the horizontal lever 32 picks up the pipe to position III, moves it to position IV, with further movement the pipe (candle) abuts into the inclined face (pillar 31) of the lever 32 and begins to slide along it towards the section formed by the bar a (position A) and the stop b, and the transfer lever moves the tube (candle) from position III to position V and VI, then winds up bottom of pipe into section to the stop b. Similarly, the following pipes are installed until the section is completely filled, then the horizontal lever 32 is rotated so that between the rows of installed pipes and the bar and the distance is slightly larger than the size of the pipe sleeve, and the next row and so on are installed. d.

After filling one half of the candlestick, turn the horizontal lever 32 to the other side and install the pipes in the same way. At the same time, the flap 41 is turned.

To rotate the lever at a certain angle, depending on the installed pipes, the corresponding risks on the dividing head (not shown) are carried out on the lever and the stand.
