Embodiment Construction

[0026] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0027] Such as figure 1 The shown automatic drilling self-locking device of a rotary drilling rig includes a self-locking pilot valve 1, an annular self-locking electromagnet 2, a pressure plate 3 and a handle 4, and the pressure plate 3 is fixed on the bottom end of the handle 4. The self-locking pilot valve 1 is correspondingly arranged under one side of the pressure plate 3, and the annular self-locking electromagnet 2 is sleeved on the top of the self-locking pilot valve 1. When the handle 4 is pressed down to the maximum position, the annular self-locking electromagnet 2 can be connected with the pressure Disc 3 sucks and locks.

Abstract

The invention relates to a rotating drill rig automatic drilling self-locking device, drilling control system and control method. The rotating drill rig automatic drilling self-locking device includesa handle, a pressure plate, a power head motor, a main valve, a self-locking pilot valve, a ring self-locking electromagnet, a pressing solenoid valve, a main pump, an auxiliary valve, a floating solenoid valve, a winch motor and a pressing oil cylinder; and the drilling self-locking function of a power head can be achieved, the pressing linkage can be controlled through the system, the intelligent operation of automatic drilling can be realized, the fatigue intensity of operators can be lowered, and construction efficiency is improved.

Description

[0001] Technical field: [0002] The invention relates to the technical field of rotary drilling rigs, in particular to a rotary drilling rig, an automatic drilling self-locking device for a rotary drilling rig, an automatic drilling control system and a control method. [0003] Background technique: [0004] Rotary drilling rig is a kind of hole-forming mechanical equipment with a high degree of electromechanical integration. It is often used in pile foundation construction. Drilling is a key link in the operation cycle. However, the construction strata are complex and diverse, and the various strata are very different. The most troublesome is the rock strata, especially the moderately weathered and slightly weathered rock strata. It often takes several hours of continuous drilling to drill a single pile. However, this process requires the operator to continuously perform the same action, which brings severe visual and muscle fatigue to the operator, making the operator misera...
