A drilling rig transformed from an excavator

Abstract

The invention discloses a drilling machine formed through transformation of an excavator. The drilling machine comprises an excavator body, an excavator forearm and a drilling machine working portion, wherein the drilling machine working portion replaces a bucket, is installed at the lower end of the excavator forearm through a rotary shaft, and can rotate with the axial direction of the rotary shaft as a circle center; the drilling machine working portion comprises a long maintenance working device and a drilling rod stand column assembly; the upper end of the maintenance working device is installed at the lower end of the excavator forearm through the rotary shaft; a hydraulic cylinder is installed on the excavator forearm, a cylinder body of the hydraulic cylinder is fixed to the excavator forearm, and a piston rod of the hydraulic cylinder is connected with the upper portion of the maintenance working device; and the drilling rod stand column assembly is installed on the maintenance working device through an installation shaft, a swinging oil cylinder is connected between the drilling rod stand column assembly and the maintenance working device, and through telescoping of the swinging oil cylinder, the drilling rod stand column assembly rotates with the axial direction of the installation shaft as a circle center.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a drilling rig transformed from an excavator. Background technique [0002] The main function of the drilling rig is to drive the drilling tool to break the rock at the bottom of the hole, and to lower or raise the drilling tool in the hole. It can be used to drill cores, ore cores, cuttings, gaseous samples, liquid samples, etc., to ascertain the conditions of underground geology and mineral resources. At present, drilling rigs are widely used in blast hole drilling operations in mines, coal, building materials, hydropower construction, highways, railway engineering and other earthwork engineering. Existing drilling equipment has some defects in design, which are mainly manifested in: (1) When the parts on the pushing beam need to be repaired and maintained, there will be no support after the pushing beam is rotated to the horizontal position.

AI Technical Summary

Problems solved by technology

Existing drilling equipment has some defects in design, which are mainly manifested in: (1) When the parts on the pushing beam need to be repaired and maintained, there will be no support after the pushing beam is rotated to the horizontal position. It is beneficial to the safety of maintenance personnel; (2) The existing drilling rig propulsion beam adopts a channel steel structure, because the propulsion beam carries many parts, which is heavy and easy to deform; (3) The dust catcher is fixed at the lower end of the propulsion beam and cannot Adjust the position flexibly. During the drilling operation, under the action of the impact force, there will be a large gap with the drilling hole plane, and the dust leakage will be large, which is not conducive to environmental protection; (4) The replacement of the existing drilling rig drill rod is manual method, which not only affects the efficiency of the drilling operation, but also increases the labor intensity of the operator; (5) The existing rock drill push trolley and the push beam are generally connected by a sliding connection, and the contact surface of the sliding connection is relatively large. During the running process, the resistance received by the propelling trolley is relatively large, which increases the energy consumption of the power source
