Abstract

The invention discloses a grabbing structure for automatically grabbing a pipe rod, which comprises a grabbing mechanism, the grabbing mechanism is fixedly arranged on a claw base, one end of the claw base is provided with a sensing assembly which senses the grabbing mechanism, and one end of the grabbing mechanism is provided with a grabbing hydraulic cylinder which is matched with the sensing assembly. A support connected with the grabbing hydraulic cylinder is arranged in the middle of the claw base. The position of the pipe rod is fed back through the sensing assembly, the grabbing mechanism can accurately grab the pipe rod under feedback of the sensing assembly, then the grabbing hydraulic cylinder is used for driving the grabbing mechanism to clamp or loosen the pipe rod, the grabbing mechanism can clamp or loosen the pipe rod more flexibly, the operation difficulty is effectively reduced. The grabbing hydraulic cylinder and the grabbing mechanism are fixedly connected through the claw base, the structure is simplified, the installation process is simplified, meanwhile, cost is reduced, and the pipe rod conveying and placing efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of oil field workover operation equipment, and in particular relates to a grabbing structure for automatically grabbing pipe rods, a lifting device and equipment thereof. Background technique [0002] Usually, several pipes and rods need to be used during workover operations in the oil field. The traditional transportation and placement of pipes and rods are carried out by manual rolling and pulling. risk of damage, etc. [0003] At present, the transportation and placement of pipes and rods is carried out by hoists or transporters, which can reduce the labor force. However, due to the harsh environment of oil field workover operations, there are greater safety risks in larger hoists or transporters, and the operation It is difficult, and it is not suitable for the placement of pipes and rods in oil field workover operations. [0004] At this stage, there is an automated manipulator for the transportation ...
