Description

The invention relates to the mining industry, in particular, to devices that allow the process of installing spark plugs for drilling pipes to be carried out during tripping operations during the drilling of exploration wells.

The purpose of the invention is to simplify the construction of a device for installing spark plugs for drill pipes.

FIG. 1 shows a device for installing spark plugs for drill pipes; FIG. 2 is a section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The device contains a frame 1 with guide grooves 2, in the bottom 3 of which longitudinal grooves 4 are made. Under the grooves there are guides 5 along which the carriage 7 of the mechanism for moving candles is moving on rollers or rollers 6. For movement of the carriage 7, translational movement actuator 8 is installed under the chutes, for example a pneumatic cylinder. In the carriage 7, there are holes for installation 9; removable pushers 10 made in the form of a crescent-shaped scraper rod, the longitudinal peaks 4 made in the bottom of the grooves 2 serving simultaneously to drain the flushing fluid.

The holes 9 in the carriage 7 are located under the slots 4 and their number is equal to the number of slots.

The device works as follows.

After lifting the spark plug of the drill pipe 11 out of the borehole, it is installed in the guide chute 2 behind the rod pusher 10 with the help of an elevator. Then, the translational drive 8 is turned on, which is connected with the carriage 7 and moves it through the rollers 6 installed in the guides 5, This rod pusher 10 is installed in the hole 9 of the carriage 7 and moves with it along the longitudinal groove 4, interacts with the end of the plug and moves it along the guide chute to the extreme right position. By reversing the drive, the carriage with the pusher returns to its original position. After installing one row of candles, a removable pusher is placed in the next hole of the carriage, made under the second guide chute, the next row of candles is installed, and the process of installing candles of drill pipes continues until the entire candlestick is filled.
