Automatic lubricating device for steel wire rope for swabbing truck

Abstract

The invention discloses an automatic lubricating device for a steel wire rope for a swabbing truck. The device comprises a shell, oil cavities, a trigger mechanism and a switching connecting rod, wherein the oil cavities, the trigger mechanism and the switching connecting rod are arranged in the shell; the shell is fixed on a running track of the steel wire rope of the swabbing truck, and a passing channel which allows the steel wire rope to penetrate through the shell is formed in the shell through sliding mechanisms; the oil cavities are distributed on the periphery of the steel wire rope ina surrounding mode, first oil outlet holes are formed in the bottom of the wall surface, facing the steel wire rope, of the oil cavities, and a spigot structure for limiting a switching joint is arranged on the outer sides of the first oil outlet holes; the trigger mechanism is clamped on the steel wire rope, and generates displacement / idling due to friction force in the operation of the steel wire rope; and the switching connecting rod is connected between the parts, at the trigger mechanism and the first oil outlet holes, of the spigot structure, and cooperates with the displacement / idlingstate of the trigger mechanism on the steel wire rope so as to enable the switching joint to be capable of achieving switching between two kinds of stations which allow the first oil outlet holes inthe oil cavities to be opened or plugged. According to the device, the steel wire rope of the swabbing truck can be conveniently, efficiently, timely, fully and stably lubricated.

Description

technical field [0001] The invention relates to a lubricating device, in particular to a lubricating device for a steel wire rope, more specifically, an automatic lubricating device for a steel wire rope used in a swabbing vehicle. Background technique [0002] Swabbing is a liquid drainage method that uses a pump rod and a pump with a rubber ring and a valve to lift up and down in the tubing, so that the liquid in the well is discharged out of the well. Swabbing is used to reduce the fluid column pressure in the well, induce oil flow or test the production of low pressure and low production wells. That is to say, swabbing is a liquid drainage test production technique in the field of oil and gas field development. [0003] The suction truck is an important tool for the implementation of the suction method. It is connected by a wire rope and drives the downhole tools to perform corresponding lifting and lowering actions in the well. During the operation of the suction truc...

Problems solved by technology

In fact, the suction truck often breaks due to insufficient lubrication of the wire rope during operation, which causes complex situations in the mine, seriously affects the production progress on site, and causes large economic losses

[0004] However, in the existing pumping car technology, there is no technology that can automatically lubricate the wire rope.

For a long time, the lubrication of the steel wire rope of the pumping vehicle has been realized by manually applying lubricating oil, which not only makes the labor intensity of the lubricating workers high, but also poses a great safety risk, and there is a lubrication cost in the way of manually applying lubricating oil High, low lubrication efficiency, untimely and insufficient lubrication, resulting in poor lubrication effect of the wire rope of the swabbing car. The main cause of frequent fracture phenomena
