Automatic drill pipe assembly and disassembly mechanism of trenchless horizontal directional drilling machine

Abstract

The invention discloses an automatic drill pipe assembly and disassembly mechanism of a trenchless horizontal directional drilling machine. The automatic drill pipe assembly and disassembly mechanism is convenient, quick and reliable to use and comprises a beam and a power head device which is slidingly arranged on the beam, a left drill pipe box fixing base and a right drill pipe box fixing base are fixed on the beam, jacking oil cylinders are fixedly arranged on the inner side of the left drill pipe box fixing base and the inner side of the right drill pipe box fixing base respectively, jacking plates are arranged on piston rods of jacking oil cylinders, drill pipe boxes are fixedly arranged on the left drill pipe box fixing base and the right drill pipe box fixing base through bolts, a left supporting base and a right supporting base are fixedly arranged on the beam between the left drill pipe box fixing base and the right drill pipe box fixing base respectively, upper pipe supporting bases are arranged on the left supporting base and the right supporting base respectively, supporting steps which are matched with drill pipes are arranged at front ends of upper pipe supporting bases, and magnet sheets are arranged at upper ends of supporting steps and on side faces of supporting steps.

Description

technical field [0001] The invention relates to a non-excavation horizontal directional drilling machine, in particular to an automatic loading and unloading drill rod mechanism of the non-excavation horizontal directional drilling machine. Background technique [0002] During the construction process of trenchless horizontal directional drilling rigs, automatic rod loading and unloading mechanisms are generally used. The existing automatic rod loading and unloading mechanisms are mainly composed of: drill pipe box, drill pipe grabbing mechanism, drill pipe lifting device, drill pipe It is composed of a translation device and a drill pipe unscrewing mechanism. Its actions are numerous and complicated, and misoperation, unreliable work, drill pipe slipping, failures and other situations often occur, and may even cause major accidents such as collapse of drilled holes and buried drills. The existing automatic loading and unloading mechanism cannot guarantee the accuracy, coo...

AI Technical Summary

Problems solved by technology

Its actions are numerous and complicated, and misoperation, unreliable work, drill pipe slipping, failures, etc. often occur, and may even cause major accidents such as collapse of drilled holes and buried drills.

The existing automatic loading and unloading mechanism cannot guarantee the accuracy, coordination, reliability and stability of each action at all, and the efficiency is extremely low, and the construction cost remains high. At present, some construction units even prefer to use the most primitive construction method ——Manual loading and unloading, and unwilling to use the existing automatic loading and unloading mechanism for construction, which greatly increases the labor intensity of construction personnel

At the same time, the design of the existing automatic loading and unloading rod mechanism itself is bulky and complicated, the production and processing of the product are complicated, and the adaptability is poor, which cannot meet the needs of modern production and processing.
