Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to an oil well pipe operating device suitable for storing and loading a tubular drilling drill (hereinafter referred to as a drill pipe) used in oil well drilling. .

(b) Conventional technology A drill pipe is pulled up from an oil well on a platform set up to excavate oil, disassembled, and stored in a fixed location.
Additionally, during work, the drill pipe must be returned to its designated location. The drill pipe is 30 meters long and is stored perpendicular to the oil well tank.

Traditionally, such drill pipes have been operated manually, by an operator-operated machine, or by a hydraulically operated machine.

(c) Problems to be solved by the invention However, in the above-mentioned manual or operator-operated work, the operator's vision is relied upon, making it difficult and inaccurate to adjust various operations. ,
There was a problem that there was a risk of an accident occurring.

(d) Means for solving the problem This invention was made by paying attention to the above-mentioned problem. The present invention aims to solve the above-mentioned problems by providing a first support member and a second support member that moves parallel and perpendicular to the first support member, and providing grips at several locations on the second support member.

(e) Examples An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention placed on a deck of an oil well platform, FIG. 2 is a side view of the same, and FIG. 3 is an enlarged sectional view of the gripping body.

The oil well pipe operating device includes a first support member 1 extending vertically.
, and the first support member l is comprised of a U-shaped channel member. The first support member 1 is a hydraulic motor 10
It is connected to the carrier 12 via a rotating part 9 that rotates in the direction of arrow B. The carrier 12 is moved in the direction of the arrow by the hydraulic device 11 on a rail 15 placed on a deck 20 of the platform.

The second support member 2 is provided adjacent to the first support member l,
It is connected to the first support member l by an articulated arm 6 actuated by a hydraulic device 7. The second support member 2 is provided with grips 3 at appropriate locations, and a pipe 8 is held by a hydraulic device 4.
Hold on to it firmly or break away from it.

The second support member 2 is formed somewhat longer than the first support member l, and the second support member 2 is supported on the first support member 1 by an articulated arm 6 actuated by two hydraulic devices 7. Therefore, in addition to the back and forth movement of the first support member 1 as shown by arrow A and the rotational movement of arrow B, the second support member 2 can also perform horizontal movement as shown by arrow C and vertical movement as shown by arrows. I can do it. The series of drill pipes is constituted by drill pipes 8.8' having a length of approximately 30 m, and during use, the drill pipes 8 suspended vertically in the hole 16 are stored at the position of the drill pipes 8', which are indicated by chain lines. drill pipe 8
The vertical movement indicated by the arrow is controlled by a hydraulic cylinder 5 which engages the first support member 1 and is mounted within the second support member 2. In order to easily store the drill pipe 8 in a vertical position in the well turret indicated by the dashed line 17, a suitable pipe support plate 18 and shelves 19 are provided on the deck 20 of the platform;
They are vertically spaced from each other.

The drill pipe 8 is firmly gripped by the gripper 3 driven by the hydraulic cylinder 4, raised vertically in the direction of the arrow by the hydraulic device 5 in the second support member z, and moved in the direction of the arrow A on the rail 15 by the hydraulic device 11. and move in the direction of arrow C by the articulated arm 6 driven by the hydraulic device 7.
By moving the rotary body 9 in the direction of arrow B by the rotary motor 10, the drill pipe 8 is planted on a pipe support plate 18, and is stored against a shelf 19. Drill Nog Eve 8
Contrary to the above, when using 1. The second support member is actuated and guided onto the hole 16.

Each of the above hydraulic devices can be operated by computer or remotely based on recorded data.

(f) Effects of the Invention Since this invention has the above-described configuration, there is no need for an operator to be present on the oil well turret, and there is no need to rely on the operator's vision. It has many advantages, such as being able to operate in various ways, being accurate, and posing no danger to humans.
