Mechanical clamping device for lifting and supporting oil casing

Abstract

The invention discloses a mechanical clamping device for lifting and supporting an oil casing. The mechanical clamping device for lifting and supporting the oil casing comprises a mounting plate, a mounting cover and a clamping device; a mounting groove is formed in the mounting plate; an adjusting rod is mounted on the internal side of the mounting groove; a servo motor is fixed above the mounting plate; a first driving shaft is connected to the servo motor; a second driving shaft is positioned on the left side of a vertical plate; adjusting gears are mounted on the second driving shaft and the first driving shaft; a connecting rod is positioned on the internal side of a limiting cover; a limiting hole is formed in the connecting rod; a connecting shaft is mounted on a clamping device; and the clamping device is connected with a rotating disc through the connecting shaft. According to the mechanical clamping device for lifting and supporting the oil casing, the mechanical clamping device is convenient to adjust according to the lengths and diameters of the oil casings, the adaption ability of the mechanical clamping device to the oil casings with different models is improved, themechanical clamping device is beneficial for improving the clamping stability of the oil casings with the different models, and a situation that the oil casings are loosened and fall off in the machining process can be avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a mechanical clamping device for lifting and supporting oil casing. Background technique [0002] Oil casing usually needs to use laser cutting to cut out a number of longitudinal or helically staggered gaps of certain specifications on its surface. During the cutting process, it is usually necessary to stably clamp, support and lift the oil casing. For example, the publication number is CN205739071U The distance between the left and right of the clamping support device in the Chinese authorized patent is fixed, which is inconvenient to adjust according to the length of the casing, and at the same time it is not convenient to fit the surface of the casing for stable clamping and fixing, and it is easy to loosen and fall off when the oil casing is clamped In this case, two power sources are used for driving, and it is inconvenient to carry out coordinated movement bet...
