Description

Technical Field

[0001] The invention mainly relates to drilling construction technology, in particular to a core drilling rig. Background Art

[0002] At present, core drilling rigs are widely used in geological and mineral resource exploration, hydrology, water wells and tunnel engineering drilling and construction.

[0003] At present, the vertical axis core drilling rig has a vertically arranged rock drilling track, which makes it impossible to achieve angle conversion of the coring drill bit in the vertical plane. When it comes to oblique coring drilling, this model cannot adapt, limiting its scope of application.

[0004] In the prior art, the core drilling rig is tilted and fixed by manually building a support, and then the corresponding operation is performed. However, this operation mode is firstly inefficient and consumes too much auxiliary time; secondly, there are certain safety hazards for the operators; thirdly, it is troublesome to remove the support, which increases the labor intensity of the workers, and the operation of removing the support is slower and less efficient. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a core drilling rig which has a simple and compact structure, low cost, convenient operation, wide application range, can improve drilling efficiency, and can realize oblique drilling.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A core drilling rig comprises a thrust beam, a thrust driving member, a coring drill rod, a rotary driving member, a rotary power head, a side swing hinge seat and a mounting seat, wherein the thrust driving member is mounted on the thrust beam, the coring drill rod is mounted on the thrust beam and can move up and down along the thrust beam, the rotary power head is mounted on the top of the coring drill rod, the output end of the rotary driving member is connected to the rotary power head, the rotary driving member is also connected to the output end of the thrust driving member, the side swing hinge seat forms a movable hinge with the thrust beam and the mounting seat, a side swing driving member is installed between the thrust beam and the side swing hinge seat and between the side swing hinge seat and the mounting seat, a surface formed by the side swing driving member driving the thrust beam to swing intersects with a surface formed by the side swing driving member driving the side swing hinge seat to swing.

[0008] As a further improvement of the above technical solution:

[0009] The surface formed by the side-swing driving member driving the propulsion beam to swing is perpendicularly intersected with the surface formed by the side-swing driving member driving the side-swing hinge seat to swing.

[0010] A horizontal rotary drive member is mounted on the mounting seat, a hinge frame is provided at the bottom of the rotary drive member, and the side-swing hinge seat and the corresponding side-swing drive member are both hinged to the hinge frame.

[0011] A guide column is arranged on the propulsion beam, a fixing seat is sleeved on the guide column, and the rotary driving member and the rotary power head are arranged on the fixing seat.

[0012] A rod protection sleeve is fixedly mounted on the bottom end of the guide column, and the coring drill rod is sleeved in the rod protection sleeve.

[0013] A supporting foot is provided at the bottom of the propulsion beam.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] When the core drilling rig of the present invention is used, the mounting base is connected to an excavator or other power equipment, and the rotary drive member is started. The rotary drive member drives the coring drill rod to perform rotary cutting or rotary grinding through the rotary power head. At the same time, the propulsion drive member drives the coring drill rod to move along the propulsion beam through the rotary drive member and the rotary power head to achieve coring drilling. When angle conversion is involved, one or two side-swing drive members are started to drive the propulsion beam to swing in two different vertical planes to form an inclination angle to achieve inclined coring drilling. Compared with the traditional structure, the core drilling rig realizes the angle conversion of the coring drill rod through the cooperation of the side-swing drive member and the side-swing hinge seat, thereby achieving inclined coring drilling, and has a wide range of applications; and the swing drive member and the side-swing hinge seat are both assembled on the propulsion beam, and there is no need to manually build and dismantle the bracket. The overall structure is simple and compact, and the operation is convenient, which greatly improves the drilling efficiency and reduces the labor cost. BRIEF DESCRIPTION OF THE DRAWINGS
