Problems solved by technology

[0002] The power head drilling rig of the existing engineering drilling rig has the following technical problems when adding a foot and pulling out the drill: when adding a foot, due to the small height difference between the power head and the drilling rig platform, the installation and disassembly of the short-connected drill pipe and the drill pipe cause It is very inconvenient and increases the labor intensity; when pulling out the drill and adding feet, the height of the joint between the shorted drill pipe and the drill pipe is relatively high, which brings inconvenience to the actual operation

Embodiment Construction

[0018] Combine Figure 1-3 , The present invention provides a device for quick installation and disassembly of drill rods, which is mainly suitable for external geared drill rods with internal teeth of engineering drilling rigs. The device is mainly composed of a barrel protecting mechanism, a driving mechanism and an actuator.

[0019] Among them, the upper part of the barrel protecting mechanism is provided with a cylinder 1, which can move up and down along the shorting drill rod 2, the cylinder 1 is sleeved on the outer surface of the shorting drill rod 2, and the lower part of the barrel protecting mechanism is provided with an annular steel plate 3 , The ring steel plate 3 is respectively connected with the driving mechanism and the executive structure. Preferably, the cylinder 1 and the ring-shaped steel plate 3 are welded into one body by the lug-shaped steel plate. The cylinder protection mechanism is a cylindrical structure as a whole, divided into two half cylinder pr...

Abstract

The invention provides a quick mounting and dismounting device for a drill rod. The quick mounting and dismounting device is used for inner tooth embedded outer gear type drill rods of an engineeringdriller and mainly composed of a protection cylinder mechanism, a driving mechanism and an executing mechanism. A cylinder capable of moving up and down long a short connection drill rod is arranged on the upper portion of the protection cylinder mechanism, the outer surface of the short connection drill rod is sleeved with the cylinder, and an annular steel plate is arranged on the lower portionof the protection cylinder mechanism and connected with the driving mechanism and the executing mechanism. The driving mechanism adopts hydraulic oil cylinders, operation is convenient and quick, andthe labor intensity is relieved. The executing mechanism is provided with roller ways and a steel ball, the problem that the short connection drill rod drives the dismounting device to rotate is solved, and quick dismounting and mounting between the short connection drill rod and the drill rod can be achieved.

Description

Technical field [0001] The invention relates to the technical field of engineering drilling rigs, and in particular to a quick installation and disassembly device for an internal gear-inlaid external gear type drill rod of an engineering drilling rig. Background technique [0002] The power head rig of the existing engineering drilling rig has the following technical problems during the lengthening and tripping: When the length is lengthened, the height difference between the power head and the drilling rig platform is small, which is caused by the installation and disassembly of the short drill rod and the drill rod. Great inconvenience and increased labor intensity; when tripping and lengthening, the height of the joint between the short drill pipe and the drill pipe is relatively large, which brings inconvenience to the actual operation. Summary of the invention [0003] Aiming at the problems in the prior art, the present invention provides a quick installation and disassembly...
