Anchor-rope-free oil-electricity dual-purpose workover rig controller capable of preventing long-time overload

Abstract

The invention relates to the technical field of workover rig control devices, and particularly relates to an anchor-rope-free oil-electricity dual-purpose workover rig controller capable of preventing the long-time overlaod. The anchor-rope-free oil-electricity dual-purpose workover rig controller capable of preventing the long-time overlaod comprises a workover rig main body, a controller main body, a winch and a steel wire rope; the controller main body is arranged on one side of the upper end of the workover rig main body; and two first convex grooves and two second convex grooves are sequentially formed in the top of the workover rig main body from left to right. The anchor-rope-free oil-electricity dual-purpose workover rig controller capable of preventing the long-time overlaod has the beneficial effects that by utilizing an arranged buffer device, when a workover jig works in an overload state, the buffer device applies a leftward pulling force to the winch, and then the winch slowly moves rightwards, so that the winch is prevented from being damaged, and meanwhile, the tension on the steel wire rope is reduced, thereby preventing the phenomenon that the steel wire rope is broken or fractured due to the overload; and by utilizing an arranged alarm device, when the workover rig works in the overload state, the alarm device gives out alarm sound so as to remind workers that the workover rig works in the overload state.

Description

technical field [0001] The invention relates to the technical field of control devices for workover rigs, in particular to a controller for a dual-purpose oil-electric workover rig without a guyline to prevent long-time overload. Background technique [0002] The workover rig or well drilling rig is the most basic and main source of power in workover and downhole operations. Aiming at the current situation of oilfield workover rigs, combined with the current development trend of workover rigs, and based on the concepts of safety, high efficiency, energy saving and environmental protection, we have designed a dual-purpose oil-electric workover rig without guy ropes. The comprehensive performance index is higher than the traditional drive system. The system has the characteristics of large starting torque, small starting current, high system efficiency, and good energy-saving effect. The system power can be set according to the capacity of the well site transformer to ensure ...

Problems solved by technology

The workover rig is prone to overload in actual use. If the wire rope is overloaded for a long time, the wire rope will be broken, and in severe cases, the wire rope will break, which will cause the hook of the traveling car to fall, causing incalculable losses. Delay the construction period, and it is easy to cause accidents to hurt the staff on site
