Problems solved by technology

[0002] With the continuous development of my country's petroleum equipment, elevators are an indispensable equipment. However, at this stage, manual elevators or simple hydraulic elevators are used more often. The degree of automation is not high, and the labor intensity on site is high.
Even if a hydraulic elevator is used, because there are many control hydraulic pipelines, a separate external hydraulic source is required. Many external factors make the simple hydraulic elevator unusable

Embodiment Construction

[0033] Such as figure 1 , 2 , 3, in one embodiment of the present invention, the power elevator includes an elevator body and a power device installed in the elevator body, and the elevator body includes an elevator body 11, a left valve 12, a right valve 13, an inner The liner 14, the latch 15 and the safety mechanism 16, the power unit includes a power unit 21, a control cable 22, a control box 23, a control valve, a valve driving cylinder, a latch driving cylinder and a power linkage mechanism;

[0034] The two ends of the elevator main body 11 are respectively movably connected with the left valve 12 and the right valve 13, for example, through the connection pin 3 for rotatable connection, and the lining 14 is arranged inside the elevator main body 11, the left valve 12 and the right valve 13. It should be noted that there is a space for the inner liner 14 arranged on the right valve 13 to rise and fall. Common, so I won't go into too much detail. On the left shutter 1...

Abstract

The invention discloses a power elevator and a control method thereof. The power elevator comprises an elevator body and a power device; the elevator body comprises an elevator main body, a left valve, a right valve, linings, a plunger latch and a safety mechanism, the left valve and the right valve are movably connected to the two ends of the elevator main body separately, the linings are arranged on the inner sides of the elevator main body, the left valve and the right valve, the plunger latch is movably connected to the left valve, and the movable safety mechanism is arranged on the rightvalve; and the power device comprises a power unit, a control valve, a valve driving cylinder, a plunger latch driving cylinder and a power connecting rod mechanism, the power unit is connected with the control valve through a pipeline, the control valve is connected with the valve driving cylinder and the plunger latch driving cylinder separately, the valve driving cylinder is connected with theleft valve and the right valve through the power connecting rod mechanism, and the plunger latch driving cylinder is connected with the plunger latch through the power connecting rod mechanism. According to the elevator, the power device is integrated into the power elevator body, therefore, hydraulic pipeline connection is reduced, energy consumption is reduced, automatic control of the elevatorcan be achieved, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of oil drilling and workover wellhead equipment, in particular to a new type of power elevator for suspending drill pipes, oil pipes, casing drill collars and other pipe strings and a control method thereof. Background technique [0002] With the continuous development of my country's petroleum equipment, elevators are an indispensable equipment. However, at this stage, manual elevators or simple hydraulic elevators are used more often. The degree of automation is not high, and the labor intensity on site is high. . Even if a hydraulic elevator is used, due to the large number of control hydraulic pipelines, a separate external hydraulic source is required. Many external factors make the simple hydraulic elevator unusable. [0003] Therefore, in view of the current situation, it is urgent to develop a new type of electro-hydraulic power elevator to overcome the shortcomings of the above elevators, and to help the rapi...
