[0042] figure 1 This is a block diagram of the operation steps of the mast vertical adjustment control method provided by the first embodiment of the present invention, please refer to figure 1 .

[0043] The mast vertical adjustment control method provided in this embodiment includes the following steps:

[0044] S1: Receive the effective signal of vertical adjustment. The effective sag adjustment signal is issued by the operating switch and transmitted to the controller. After the controller receives the effective sag adjustment signal, the mast sag adjustment control device enters the sag adjustment mode and the sag adjustment function is turned on.

[0045] S2: Detect the current mast angle value. The angle of the mast is detected in real time by the inclination sensor. The inclination sensor sends the current mast angle to the controller.

[0046] S3: Calibrate the mast angle. According to the current mast angle value, judge whether it is within the adjustable range of sag adj...

[0079] The mast drooping control device provided in this embodiment includes a controller, an operation switch, an inclination sensor, a display, and an electric control valve group. The controller is connected to the operation switch, an inclination sensor, the display, and the electric control valve group, respectively.

[0080] The operating switch is used to send a sag signal to the controller. The tilt sensor is used to detect the mast angle. The controller selects the current output parameter from the preset current parameter curve according to the mast angle detected by the tilt sensor, and controls the electric current according to the current output parameter. The output current value of the control valve group, the display is used to display the current angle of the mast and display current output parameters and other related information, and the electronic control valve group is used to adjust the mast angle until the mast angle is zero.

[0081] Specifically, the control...

Abstract

A mast verticality adjustment control method and device provided by the invention relate to the technical field of rotary drilling rigs. The mast verticality adjustment control method comprises the following steps: receiving an effective verticality adjustment signal; detecting the current angle value of a mast; calibrating the angle of the mast; selecting current output parameters from a preset current parameter curve according to the current angle value of the mast; and controlling the output current value according to the current output parameters, and adjusting the angle of the mast untilthe angle of the mast reaches zero. According to the mast verticality adjustment control method, the requirement parameters in the use of equipment can be automatically identified, the use parameterscan be automatically modified in order to meet the use conditions, and the use parameters of the mast can be automatically discriminated, so that the separate configuration of control parameters for each piece of equipment and the change of parameters after long-time use are avoided. The mast verticality adjustment control device provided by the invention has a function of self-adjusting the verticality adjustment parameter curve of the mast of a rotary drilling rig, and has strong adaptability.

Description

Technical field [0001] The invention relates to the technical field of rotary drilling rigs, in particular to a mast vertical adjustment control method and a device thereof. Background technique [0002] At present, the method of the mast control system of rotary drilling rigs is generally that the handle signal is transmitted to the controller. The controller determines the output current according to the signal of the inclination sensor, and finally acts on the mast action valve block to control the mast movement, ensuring stability Under the premise of controlling the verticality of the mast. [0003] This control method has the following shortcomings: each device needs to set the mast control parameters; after the hidden danger of shaking, a new set of parameter programs needs to be updated; there is the hidden danger of the mast shaking back and forth when adjusting the sag during use, etc. problem. Summary of the invention [0004] The purpose of the present invention is to ...
