Oil rig racking platform string discharge manipulator

Abstract

The invention provides an oil rig racking platform string discharge manipulator which comprises a manipulator body, a manipulator arm, a swing mechanism and a mounting seat, wherein the manipulator arm is hinged at the lower end of the manipulator arm, the upper end of the manipulator arm is connected with the swing mechanism, and the swing mechanism is arranged on the mounting seat. The manipulator body comprises a connecting seat, two manipulator fingers and a manipulator open-close driving mechanism, wherein each manipulator finger comprises multiple linear finger segments and arc joint segments which connect each of two adjacent linear finger segments, and the opening and closing of the manipulator body is realized by the manipulator open-close driving mechanism which drives the manipulator fingers to overturn. Each finger of the manipulator body is of a structure connected by the linear finger segments and the arc joint segments at intervals so as to be bent more smoothly. Therefore, when the manipulator open-close driving mechanism drives the manipulator body to overturn downwards and overturn till the manipulator body is in the opening state, the finger portion cannot expand outwards, the overall width cannot be enlarged, the fingers can be inserted and taken out of the arranged string conveniently, the discharge efficiency of the string is improved, and the discharge density cannot be reduced.

Description

technical field [0001] The invention relates to an auxiliary mechanical device of an oil drilling rig, in particular to a structural improvement for a manipulator for discharging pipe strings on the second-floor platform of an oil drilling rig. Background technique [0002] With the development of science and technology, the discharge of the second floor pipe string of oil drilling rig is usually carried out by manipulator device. In the prior art, the manipulator for pipe string discharge includes a manipulator, a manipulator, a rotary mechanism and a mounting seat. On the platform derrick. When the pipe string is discharged, the action of the slewing mechanism drives the mechanical arm to rotate to the discharge position, and the opening and closing action of the manipulator carries out the grabbing and discharging of the pipe string. [0003] The prior art has the following disadvantages and deficiencies: when the pipe string is finished or when the pipe string is deep ...

AI Technical Summary

Problems solved by technology

[0003] The prior art has the following disadvantages and deficiencies: when the pipe string is finished or when the pipe string is deep into the densely discharged pipe string to grab the pipe string, the manipulator needs to be opened. Driven by the combined driving mechanism, it is realized by moving back and forth or opposite to each other. After the manipulator is opened, the overall width of the fingers becomes larger. The width of the finger beam will increase the discharge gap of the pipe string on both sides of the finger beam, which will reduce the discharge density of the pipe string and affect the discharge efficiency of the pipe string
