Problems solved by technology
However, most of the drill pipe conveying devices currently developed in our country have single functions and large working limitations. They have poor stability during operation and are easy to cause damage to the drill pipe thread and the rod body, which will bring many problems in practical applications. unfavorable factors

Embodiment Construction
[0020] The present invention will be further described below with reference to accompanying drawing:
[0021] Such as figure 1 Shown: a ground drill pipe lifter, mainly including a platform 1 and a lifting frame 2, the platform 1 and the lifting frame 2 are connected by a rotating mechanism 11, and the lifting frame 2 can rotate around the rotating shaft of the rotating mechanism 11 rotate.
[0022] A drill pipe conveying device 3 is installed on the outside of the stand 1, and the drill pipe conveying device 3 is driven by a hydraulic cylinder 4, and the drill pipe conveying device 3 can convey the ground drill pipe to the limit groove 17 of the lifting frame 2;
[0023] Two hydraulic lifting mechanisms 9 are installed in the platform 1, when the lifting frame 2 falls to the position of the platform 1, the lifting mechanism 9 stretches out, and through the square hole 16 in the lifting frame 2, the The drill rod 18 is held out from the limiting groove 17.
[0024] The lift...

A ground drill rod lifting device comprises a table frame and a lifting frame which are connected through a rotary mechanism. The lifting frame can rotate around a rotary shaft of the rotary mechanism, a drill rod conveying mechanism can overturn drill rods from the ground into a limiting groove in the lifting frame, and a drill rod bearing mechanism can adjust the extension lengths, at the end of the lifting frame, of the drill rods. A drill rod clamping mechanism can lock the drill rods into the limiting groove in the drill rod lifting process, the lifting frame can be pushed to be overturned through a lifting hydraulic cylinder, and the drill rods are lifted to a preset position of a drilling platform. Additionally, the drill rods can also be conveyed back to the ground from the drilling platform through the opposite process. The ground drill rod lifting device is safe and reliable, on the basis that the operation stability and efficiency are improved, the structure is simplified, the limitation of existing equipment in the using process is overcome, and the conveying task of the drilling rods of different models in a well field can be completed.
Description
technical field [0001] The invention belongs to the technical field of drilling rod lifting devices for petroleum machinery, and in particular relates to a ground drilling rod lifting device. Background technique [0002] In the field of oil drilling, the delivery of drill pipe is an important factor affecting the drilling efficiency. During the drilling process, land oil drilling rigs spend about 40% of their time processing drill pipe. my country's traditional land drilling rigs mainly use drill floor drawworks and cranes to complete the transportation of drill pipes on the well site. During the transportation of drill pipes, electric or pneumatic small winches are generally used to connect wire ropes to lift the drill pipes up and down the drilling site. It is one of the most dangerous jobs in drilling operations that must be completed with the cooperation of the derrick worker during tripping and tripping operations. In addition, this work is highly repetitive and labor...
