Description

Rod holder for increasing or changing the link of the rod during the sucker-rod (punching) drilling of holes.

It was filed on October 19, 1938 in NKNeft, No. 19391. Published on July 31, 1940.

The proposed rod holder for increasing or changing the link of the rod during the rod (punching) drilling of bore-holes facilitates the production of this operation by eliminating turning the rod, which is in the hole, and provides for rapid expansion of the rod, which increases the productivity of the driller.

The tube holder is provided with a collar at one end, by means of which it is fixed on the CONSOL stop pipe, fixed in the auxiliary hole by wedging the stop bars with the pick of the rod, and at the other end carries the collar integral with the clamp rod.

In FIG. 1 depicts a side view of a rod holder for increasing the OR of a link of a rod link in the case of a rod (punching) drilling holes; FIG. 2 - front view; FIG. 3 is a horizontal section through aa of FIG. one; FIG. 4 is a vertical section through bb of FIG. one.

Near the hole with a hole of a drill (punching) drill is drilled

a small auxiliary hole into which the cantilever abutment tube 6 of the rodholder is inserted. In the pipe 6 there is a rod / fitted at the end with a lance, by means of which, during rotation of the spindle shaft 2, the extension strips 3, equipped with leaf springs 3, are pushed outward and fixed by means of wedging the pipe 6 in the hole. A pipe 4 is strengthened on pipe 6 using a hotsuit 5. At the other end of pipe 4, a mobile collar 7 is secured, which is integral with the clamping device 8, 9 FOR the drill rod A.

When raising or changing the link of the rod, the pipe 4 with the collar 7 is supplied to the rod A, and the latter is fixed by means of the pressure plate 10 connected to the spring screw 11 carrying the steering wheel 12 in the required place.

Unscrewing the bar and screwing the next link, the bar A is released by unscrewing the clamping screw. Pipe 4 is appropriately retracted to the side; further drilling is performed.

with the subsequent repetition of these operations.

The subject matter of the invention

Rod for parashchivaniya or change the link rod when the rod (punch) drilling holes, characterized by the use of

pipe 4, one end of which is provided with a collar 5 for securing it to the anvil pipe 6 secured in the auxiliary hole with the help of a drill pin and / and the other end for securing the collar 7 constituting one piece with the clamping device 8, 9 for drill rod.
