Vertical axis type drilling machine inclined hole boring machine

Abstract

The invention relates to a spindle-type drilling machine with angular hole drilling function. According to the technical proposal provided in the invention, a rotary bearing is provided on the chassis, a drilling tower bracket is provided on the rotary bearing, a drilling tower is hinged on the drilling tower bracket, a drilling machine body and the output rotary main shaft thereof are provided on the drilling tower, and an angle adjusting mechanism for adjusting the angle of the drilling tower is disposed between the drilling tower bracket and drilling tower. A rotary bearing is arranged between the drilling tower and chassis, so that the drilling tower can conveniently realize the conversion between transporting state and working state, the drilling hole angle of the drilling device can be randomly and continuously adjusted in the range of 0-90 DEG, the application range of the spindle-type drilling machine is increased, and the spindle-type drilling machine can also realize the functions of full-hydraulic power drilling machine. The invention can fully utilize the existing large amount of spindle-type drilling machine; and has the advantages of good economical performance, low production cost, saving a large amount of investment cost, quicker arrangement and relocation of equipment, good safety and reliable performance.

Description

technical field [0001] The invention relates to a kind of drilling which must be combined with a drilling tower in order to meet the requirements of the drilling process of drilling inclined holes, such as tripping drilling tools and handling accidents in the hole, during the drilling process of inclined drilling holes by using a vertical shaft drilling rig. equipment. Background technique [0002] The proportion of inclined hole drilling required in modern drilling projects is increasing. The use of advanced full hydraulic power head drilling rigs can meet the needs of drilling holes with any inclined angle, and the drilling efficiency is high and the drilling quality is good. However, the manufacturing cost of advanced full hydraulic power head drilling rigs is high and requires a large amount of capital investment, so traditional vertical shaft drilling rigs are still widely used to carry out the construction of drilling holes. The drilling process requires that the vert...

Problems solved by technology

Traditional four-legged towers, A-shaped towers or triangular supports are mainly equipped for vertically downward drilling holes, and their structures are mostly in the form of trusses, which are assembled from scattered rods at the drilling construction site, with large bearing capacity and stability. However, when drilling inclined holes, when the axis of the rotary vertical shaft of the drilling rig changes according to the inclination angle of the drilling hole, it is often difficult to achieve the same angle of the drilling tower, which will affect the drilling tower. The overall stress performance will lead to safety accidents in serious cases, especially when the inclination angle of the drilling hole needs to be changed frequently, the work of adjusting the inclination angle of the drilling tower will become very complicated and cumbersome, not only labor-intensive, but also directly lead to drilling Hole construction safety and drilling efficiency decline; it can be seen that the use of traditional vertical shaft drilling rigs and four-legged towers, A-shaped towers or triangular brackets can no longer meet the needs of modern drilling multi-angle oblique hole drilling
