Embodiment 1

[0058] A hydraulic elevator control system, such as Figure 1 to Figure 6 As shown, it includes the first reversing solenoid valve 101 for controlling the opening / closing of the elevator, and the control oil circuit for controlling the opening / closing of the elevator through the first reversing solenoid valve 101, and the control oil circuit for driving Execute the oil cylinder to control the opening / closing of the elevator;

[0059] The executive oil cylinder includes a first oil cylinder 9 and a second oil cylinder 10, and the first oil cylinder 9 and the second oil cylinder 10 are connected in parallel to the control oil circuit;

[0060] The control oil circuit includes an oil inlet port P and an oil return port T. After the oil inlet port is connected to the first reversing solenoid valve 101, a first oil port 111 and a second oil port 112 are provided. Through the first The reversing solenoid valve 1 controls the first oil passage end 111 and the second oil passage end ...

Embodiment 2

[0097] A hydraulic elevator control method, comprising the following steps:

[0098] Open the elevator;

[0099] Such as figure 2 As shown, the electromagnet YV02 is energized, the elevator starts to open the door, and the first reversing solenoid valve 101 changes direction. The card executes the door opening command; the high-pressure oil circuit passes through the P port of the oil inlet port, and is divided into two branch flows after passing through the first pressure relief valve 105, and the hydraulic direction valve 103 of the branch circuit changes direction, so that the closing signal switch 202 and the return The oil terminal T is connected to complete the pressure relief, and the door closing signal switch 202 controls the door closing signal light to go out; the high pressure oil in the branch circuit 2 passes through the second directional valve 4, and flows to the fourth oil cylinder 6, and the fourth oil cylinder 6 works to open the latch, and the opening of ...

Embodiment 3

[0104] On the basis of the design of embodiment 2, with Figure 4 For example, it also includes elevator flipping;

[0105] When the elevator door is in the open state and needs to be turned up, the door opening signal is first given to YV02 to be energized, and then the electromagnet YV01 is energized at the same time, the second reversing solenoid valve 104 is reversed under the action of the electromagnet YV01, and the first overflow valve 102 oil At this time, the door opening pressure is determined by the first pressure relief valve 105, the set pressure of the first pressure relief valve 105 is greater than the pressure of the third sequence valve 309, and the high pressure oil passes through the third hydraulic control check valve 310 , the oil circuit passes through the third sequence valve 309, the balance valve 304 and the first one-way throttle valve 303 to the fifth oil cylinder 5, the jaws of the main body of the elevator start to turn up, and when it reaches the ...

Abstract

The invention discloses a hydraulic elevator control system and method, and belongs to the technical field of petroleum drilling machine devices. The system comprises a first reversing electromagnetic valve used for controlling the elevator to be opened / closed, a control oil way used for controlling the elevator to be opened / closed through the first reversing electromagnetic valve, and an execution oil cylinder used for achieving driving through the control oil way, and the elevator is controlled to be opened / closed through the execution oil cylinder. According to the hydraulic elevator control system and method, the problem that a traditional hydraulic elevator usually adopts a mechanical arm or manual operation mode is solved, the elevator opening and closing efficiency is effectively improved through hydraulic control, the automation effect is better achieved for petroleum drilling field operation, and the operation efficiency is higher.

Description

technical field [0001] The invention relates to a hydraulic elevator control system and a control method, belonging to the technical field of oil drilling rig devices. Background technique [0002] Hydraulic elevator is one of the key equipment for oil drilling. Its function is mainly used to hold drill pipe, oil pipe, casing and other pipe strings, assist other equipment, and complete the operation of drilling string. [0003] The hydraulic elevators in the prior art generally adopt a side-by-side door structure. At present, in domestic drilling and workover tripping operations, most of the elevators used are mechanical manual elevators. During the operation, workers need to manually open and close the elevators repeatedly. , the degree of automation is low, the work efficiency is low, the labor intensity of skilled workers is high, and there are potential safety hazards. As the automation and unmanned drilling has become the main development trend of petroleum equipment,...
