A new type of automated airborne anchor drilling rig

Abstract

The present invention discloses a novel automated airborne anchor drilling rig. The drilling rig includes a carriage on which a drill head is slidably mounted. A multi-stage push cylinder is fixed within the carriage for pulling the drill head for reciprocating motion. The output shaft of the multi-stage push cylinder is tightly connected to the drill head. A rod changing device for replacing drill rods is rotatably mounted on the carriage. A motor for driving the entire drilling rig is fixed to the drilling rig. The anchor drilling rig of the present invention activates the multi-stage push cylinder, causing the drill head, consisting of a drill assembly and a drill base, to reciprocate back and forth on the guide rails of the carriage as required, thereby achieving feed, drilling, and retraction. When a task is completed, the drill head is retracted to load the rod. A hydraulic handle is used to activate the rotary cylinder of the rod changing device, causing the clamping frame connected to the rotary cylinder to swing and rotate, thereby driving the drill rod frame to rotate together, and the drill rod stored on the rod changing device is delivered to the upper portion of the drill rig guide rail. The drill head then advances and pushes the drill rod into the rig, completing the rod change.

Description

Technical Field

[0001] The invention relates to the field of anchor drilling rigs, in particular to a novel automated airborne anchor drilling rig. Background Art

[0002] Airborne anchor drilling rigs are widely used in coal mine anchoring equipment. They are in great demand and have a wide range of adaptability. However, when drilling anchor holes, the drill rod length is far from meeting the drilling depth requirement, and multiple rod replacement and rod connection drilling operations are required. At present, airborne anchor drilling rigs can only clamp one drill rod at a time. After drilling a hole once, manual labor is required to pick up the rod and install the rod again. After the drill rod is drilled into the hole, the rod replacement operation needs to be repeated many times until the drilling work is completed. The labor intensity of the workers is high, the auxiliary work time is long, and the time production efficiency is not high. At the same time, when the rod replacement operation is actually required, the drilling rig is mostly at a high place, and the workers often work with loads in a dangerous state, which has obvious safety hazards. The existing airborne anchor drilling rig has a relatively complex propulsion method, and the processing and manufacturing parts are numerous and complicated. The drilling rig operation is relatively complicated, difficult to control, and prone to misoperation. For this reason, we propose a new type of automated airborne anchor drilling rig to solve the above problems. Summary of the Invention

The anchor drilling rig of the present invention starts the multi-stage push cylinder, and the drill head composed of the drill assembly and the drill seat reciprocates back and forth on the guide rail of the slide according to work needs to realize the feeding, drilling and retracting actions. Compared with the existing anchor drilling rigs, the propulsion method is simple, the control is convenient, and the occurrence of incorrect operations is reduced; when a work is completed, the drill head returns to load the rod, and the rotating oil cylinder of the rod changing device is started by operating the hydraulic handle, so that the clamping frame connected to the rotating oil cylinder is swung and rotated, and the drill rod rack is driven to rotate together through the four guide rods fixed between the clamping frame and the drill rod rack, and the drill rod rack is sent to the upper part of the drill rig guide rail. The drill head is pushed forward and the drill rod is pushed in to complete the rod changing action. Compared with the existing anchor drilling rigs, it can change rods independently, which reduces the labor intensity of workers, reduces the auxiliary work time, and improves production efficiency.
