Problems solved by technology

[0003] The length of the drill pipe is generally about nine meters, long and heavy. Therefore, it is difficult to take out the drill pipe when pulling it out, or even if it can be taken out, it will cause the drill pipe to break and require the help of equipment
There are special equipment such as extubation machines on the market, but the price is high

Abstract

The invention discloses a drill rod puller. The drill rod puller comprises a transverse beam frame and a slip, wherein the slip is arranged in the middle of the transverse beam frame; the contact surface between the slip and the transverse beam frame is an inclined plane and an included angle is formed between the contact surface and the vertical direction; a clamping hole through which a drill rod passes is formed in the middle of the slip; the slip is in a longitudinal splitting form; and the drill rod is tightly clamped by the slip and the transverse beam frame which are wedged through the inclined plane. The drill rod puller disclosed by the invention has the advantages of simple structure, low manufacture cost, and convenience for operation; the drill rod can be reliably pulled; the drill rod puller is small in size, can be mounted in site and also can be used in a complicated utilization environment so that the drill rod puller has relatively great flexibility.

Description

technical field [0001] The invention relates to a drill pipe pulling device. Background technique [0002] The drill pipe is a rod connected in the drilling tool to transmit power. It is a steel pipe with a thread at the end, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or the bottom hole device at the bottom of the drilling well. The purpose of the drill pipe is to transport the drilling mud to the drill bit, and together with the drill bit to raise, lower or rotate the bottom hole device, it must be able to withstand huge internal and external pressure, twisting, bending and vibration. [0003] The length of the drill pipe is generally about nine meters, and it is long and heavy. Therefore, it is difficult to take out the drill pipe when it is pulled out, or even if it can be taken out, the drill pipe will be broken, and equipment is needed. There are special equipment such as extubation machines on the market,...
