Abstract

The invention discloses a multifunctional robot for a drilling site. The multifunctional robot comprises a crane and a telescopic arm, wherein the front end of the telescopic arm is hinged to a ram sleeve by a connecting sleeve, the connecting sleeve and the ram sleeve are connected by a ram sleeve swinging oil cylinder to form the rotary driving fit, the ram sleeve is of a hollow structure, and sleeves the exterior of a ram, a ram rack is arranged on the ram, the ram rack is in movable fit with a ram displacement hydraulic motor speed reducer and a ram rack brake which are arranged on the ram sleeve, the lower end of the ram is in rotary fit with a manipulator machine frame through a rotary disc bearing, and a pipe grabbing gripper, a friction wheel and a floating positioning roller are arranged at the bottom surface of the manipulator bottom frame, and are connected and driven by an oil cylinder. The multifunctional robot has the advantages that the equipment, such as drill pipes, drill collars, casings and protecting pipes, required by the automatic conveying and the fetching and storage of a land petroleum drilling platform are realized, and the multifunctional robot can be widely applied to the field of automatic modification of land petroleum drilling machines and offshore drilling platforms.

Description

technical field [0001] The invention relates to the field of automatic mechanical devices for oil well site operations, in particular to a multifunctional robot for drilling sites, which can be widely used in the automation transformation of drilling and completion operation machinery on land oil drilling platforms. Background technique [0002] At present, domestic oil drilling rigs mainly rely on pneumatic or hydraulic winches to lift and lower oil pipe strings, and most of them are manually pushed from the pipe rack to the runway, which has a low degree of automation and unsafe factors. Contents of the invention [0003] One object of the present invention is to make up for the deficiencies of the prior art, and to provide a drilling system that realizes the automatic delivery and pick-up of drill pipes, drill jacks, casings, protective pipes and other management equipment required in the operation of onshore oil drilling platforms. Field-use multifunctional robot. [...
