Multifunctional motive power head of full hydraulic drilling machine

Abstract

The invention relates to a multifunctional motive power head of a full hydraulic drilling machine, which is provided with a motive power head installing seat arranged on a mast body of the drilling machine, wherein the back side of the motive power head installing seat is provided with a vertical slide guide rail surface matched with the mast body of the drilling machine, a transverse slide rail is arranged on the front side of the motive power head installing seat, a transverse slide seat body is arranged on the transverse slide rail, a rotating shaft which is arranged in the transverse direction is arranged on the upper part of the transversal slide seat body, the upper part of a motive power head assembly is fixedly connected with the rotating shaft, and both sides of the rotating shaft are provided with motive power head up-tilting turning driving oil cylinders. Sliding friction is changed into rolling friction, the fit gap is small, the vibration in the drilling is small, and thework is stable. The installation of an up-tilting turning type structure and the dismounting of a drilling rod and a drilling tool are convenient, the time is saved, and the work efficiency is improved. Large-range transverse movement of the motive power head makes the main shaft be disengaged from the center of a drilling hole, a large-diameter sleeve pipe can be conveniently dismounted, and theaccidents in the hole can be conveniently processed. The rigidity of a plug pulling device is good, the work is stable, each action and each work condition requirements of the drilling process can berealized, and the multifunction effect is really realized.

Description

technical field [0001] The present invention relates to a technical equipment for the exploration and development of coal, coal-bed methane, natural gas and other resources, especially a coal-bed methane drilling rig used in the exploration and development of coal-bed methane, gas pumping and discharge, and construction of coal mine safety and emergency projects. Multifunctional power head. Background technique [0002] With the continuous expansion of the demand for mineral resources such as coal, oil, and natural gas, the amount of mining is increasing year by year, while the reserves are getting smaller and smaller. The energy crisis is intensifying on a global scale. Seeking new alternative energy has become a social development in today's society. the only way. The exploration and development of coalbed methane is carried out under this background. Previously, the main domestic equipment used for coalbed methane exploration and development were oil drilling rigs, hydr...

AI Technical Summary

Problems solved by technology

Practice has shown that among the above types of drilling rigs, oil drilling rigs are component-assembled, which can meet the requirements of coalbed methane exploration and construction functionally. However, there are many independent unit components, the overall structure is huge, the power consumption is huge, relocation is difficult, and the construction period is long. The cost is too high, because it is driven by a turntable, has no pressurization function, the drilling efficiency is low, and it is difficult to lower the enlarged diameter casing; the traditional vertical shaft core drilling rig with mechanical transmission and hydraulic feed commonly used in the geological and coal industries requires investment in equipment Low cost, easy relocation, and the vertical shaft has a pressurization function, which can meet the drilling construction with a depth of less than 1,000 meters and a diameter of less than 300mm, but it cannot fully meet the technical requirements of coalbed methane exploration and construction (for example, large-diameter casing cannot be installed)
