Abstract

The invention relates to a portable drilling machine capable of implementing wire-line core drilling, which comprises a base, a post, a mast, an inclined support, a sliding sleeve device, a back plate, a hydraulic power supply, a hydraulic power head, a winch, a pulley, a steel wire rope, an elevator, a Trojans gripper and a feed lifting device, wherein the post is fixed on the base; the sliding sleeve device is arranged on the post; the back plate is connected with the sliding sleeve device; the hydraulic power source is connected with the hydraulic power head by a hydraulic oil pipe; the hydraulic power head is connected with the back plate; the winch is fixed on the base; the pulley is fixed on the upper end of the mast; one end of the steel wire rope is a free end bypassed through the pulley, and the other end of the steel wire rope is fixed on the winch; the elevator is connected with the free end of the steel wire rope; and the Trojans gripper is installed on the base. As the portable drilling machine disclosed by the invention is provided with the portable winch, the mast, the pulley, the steel wire rope, the elevator and the portable Trojans gripper, the wire-line core drilling can be realized.

Description

technical field [0001] The invention relates to a drilling rig, in particular to a portable drilling rig capable of wireline core drilling. Background technique [0002] At present, when drilling shallow holes with a depth of about 30m to 50m, the core drilling process is adopted. The continuous lifting, lowering, unloading and connecting of drill pipes not only seriously affect the drilling efficiency, but also It will cause damage to the hole wall and cause accidents in the hole such as hole collapse and drill sticking. Using the wireline core drilling process can solve the above problems. But there is still no portable drilling rig that can realize wireline coring drilling in the market at present, and this drilling rig is a product that is badly needed in the market. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a portable drilling rig that can implement wireline core drilling, which overcomes the need fo...
