Moving device based on linear bearing and linear motion shaft

Abstract

The invention belongs to the technical field of petroleum equipment, and relates to a moving device based on linear bearings and linear motion shafts. The moving device comprises the vertically-arranged linear motion shafts, an upper fixed disc is arranged at the upper ends of the linear motion shafts, a lower fixed disc is arranged at the lower ends of the linear motion shafts, an upper movable disc and a lower movable disc are sequentially arranged between the upper fixed disc and the lower fixed disc, the linear motion shafts are sleeved with the upper movable disc and the lower movable disc through the linear bearings, the upper movable disc and the lower movable disc are connected and fixed through connecting rods, and the upper movable disc is connected with a driving device. By adopting the combined design of the linear bearings, the upper movable disc, the lower movable disc, the driving device and the linear motion shafts, the advantages of the linear bearings and the linear motion shafts are combined, under the drive of the driving device, the upper movable disc and the lower movable disc move up and down along the linear motion shafts, and finally free lifting for an oil pumping pipe is realized.

Description

technical field [0001] The invention belongs to the technical field of petroleum equipment, and relates to a transmission device for pumping equipment, in particular to a motion device based on a linear bearing and a linear optical axis. Background technique [0002] At present, the drainage and pumping of liquid storage tanks in oilfield gas gathering stations is still in the stage of manual operation. When pumping water, the monitoring personnel remotely open the valve, and the personnel outside the station lower the pipeline of the suction port to the bottom of the liquid storage tank according to experience. When the water level is lower than about 20cm, the monitoring personnel or the PKS system remotely close the valve and stop the operation. When pulling oil, the work area arranges guardians to go to the station, and the pulling personnel insert the hose on the car into the tank. According to experience, the hose head is parked in the oil layer. When cloudy, pull out...

Problems solved by technology

[0003] However, the above-mentioned traditional methods all rely on the experience of the operators and monitors. Especially when pumping oil, they cannot scientifically and accurately locate the hauling target and control the hauling volume. Moreover, the tank area in the station is a flammable and explosive area, and personnel operations Other factors such as static electricity in the process increase potential safety hazards, and the output oil is an item with high economic value.

During the process of producing water and oil, it is impossible to accurately measure the hauling volume, and disputes often arise between the two parties on the hauling volume

In addition, due to the lack of effective control measures in the entire process of producing water and oil, the guardians, under the sugar-coated shells of criminals, connected with the inside and outside, and reselling the output oil occurred. Even if the company suffered economic losses, It is also not conducive to the harmony of the oil region
