Problems solved by technology

This method requires the staff to have certain work experience, which increases the labor intensity of the workers and affects the work progress
In addition, this method cannot detect and solve problems in time when problems occur. Often when problems are found, the drill has been stuck, and in severe cases, the machine equipment has been damaged.

Embodiment Construction

[0012] like figure 1 As shown, the mast angle automatic adjustment device for the core drilling rig has an inclination sensor, and the inclination sensor sends the collected drilling angle signal to the central processing unit, and the central processing unit analyzes and processes the drilling angle signal transmitted by the inclination sensor , the current angle information is displayed on the monitor, and the central processing unit is connected with the solenoid valve of the outrigger oil cylinder at the same time.

[0013] like figure 2 As shown, firstly, the drilling angle of the drilling tower is calibrated, and the inclination sensor collects the angle of the drilling tower in real time during drilling, and at the same time transmits the angle signal to the programmable controller; the programmable controller analyzes the signal sent by the inclination sensor, that is, through the The internal control program of the programmable controller calculates the deviation be...

Abstract

The invention discloses an automatic mast angle adjustment device for a core-drilling machine, relating to the technical field of core-drilling machines. The device is provided with a tilt sensor. The tilt sensor sends the acquired drilling angle signal to a programmable controller, the programmable controller computes the deviation between the current angle and the preset angle through the internal control programs, and if the deviation exceeds the preset angle deviation range, the programmable controller sends a control signal to a solenoid valve of a hydraulic leg and a support oil cylinder acts. The device has the benefits of being convenient to install and use, being capable of automatically adjusting the angle of the mast and keeping the angle of the mast in the required drilling angle deviation range all the time.

Description

technical field [0001] The invention relates to the technical field of core drilling rigs, in particular to an automatic mast angle adjustment device for core drilling rigs, which is suitable for automatically adjusting the angles of platforms and masts above the ground during the drilling process of core drilling rigs for exploration, so as to meet the drilling requirements of construction. angle. Background technique [0002] At present, domestic and foreign rock core drilling rigs all have no mast angle automatic adjustment device. During the construction process of the core drilling rig, the drilling construction angle is fixed. If the mast and platform are tilted due to other reasons such as ground subsidence or hydraulic outrigger leakage during long-term work, the drilling angle will change, and once the deviation is too large, it may cause a stuck drill accident. If it is not handled properly, it will also complicate the situation in the hole, thus consuming a lot ...
