Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Such as Figure 1-3 As shown, a hydraulic cylinder drives an iron driller's walking mechanism with a lifting function, including a base 1 and a suspension frame 2 installed on the base 1; the base 1 includes two translation components, and the two translation components are connected by cross braces 20; The bottom of the suspension frame 2 is connected with the two translation assemblies, and the inner side of the suspension frame 2 is connected with the pincer head assembly 19 .

[0036] Such as Figure 4 As shown, the translation assembly includes a fixed inner slide rail 4 and an outer slide rail 5 that is slidably connected, and a translation cylinder 8 installed between the inner slide rail 4 and the outer slide rail 5, that is, the inner side is realized through the telescopic movement of the translation cylinder 8 . Relative m...

Abstract

The invention discloses an iron driller's walking mechanism driven by a hydraulic cylinder with a lifting function, which includes a base and a suspension frame installed on the base; the base includes two translation components connected through cross braces; The components are connected, and the inside of the suspension frame is connected to the clamp head assembly. The invented walking mechanism uses translational oil cylinder to drive the translation of the base, canceling the bulky structure of the hydraulic motor driving the rack and pinion; The oil cylinders are equipped with linear displacement sensors, which can realize precise positioning in the horizontal and vertical directions while satisfying the walking function of iron drillers, which not only effectively reduces production costs, but also improves the controllability, smoothness of operation, and Accuracy and work efficiency are improved, and the maintainability and environmental adaptability of the iron driller's traveling mechanism are improved.

Description

technical field [0001] The invention belongs to the technical field of petroleum drilling and production equipment, and relates to a traveling mechanism of an iron driller driven by a hydraulic cylinder with a lifting function, and an adjustment method of the traveling mechanism. Background technique [0002] As an advanced torque make-up and break-out equipment, the iron drilling machine can complete make-up and break-out of drill pipes, drill collars and other drilling tools in automatic drilling production, improving production efficiency and safety. At present, the iron drillers used in oil fields mainly include telescopic arm type, track type, and suspension type. Therefore, it is more used in marine working environments such as floating platforms and semi-submersible ships. [0003] However, judging from the current use of rail drillers on offshore platforms, the traveling mechanism of most rail drillers uses symmetrically arranged dual hydraulic motors to drive rack ...
