Abstract

The invention belongs to the technical field of drilling rig equipment, and proposes a self-propelled double-column drill carriage which is characterized by comprising a chassis. A travelling track isarranged below the chassis, the chassis is provided with a column, a guide rail is rotatably arranged at the middle of the column, a rotator is slidably arranged on the guide rail, the column includes a bottom pillar arranged on the chassis, the upper portion of the bottom pillar is connected with a pneumatic telescopic pillar, a first abutting seat is hinged to the top of the pneumatic telescopic pillar, rotating supporting rods are also rotatably arranged on the chassis, a rotating shaft of each rotating supporting rod is arranged in the horizontal direction, the length of the rotating supporting rod is larger than the distance between the chassis and the ground, the rotating supporting rod is telescopic and can be locked, the number of the rotating supporting rods is four, the rotatingsupporting rods are located at four corners of the chassis respectively, and a second abutting seat is hinged to one end of the rotating supporting rod far away from the chassis. According to the self-propelled double-column drill carriage, the problems that when a drilling rig is in drilling process, the chassis is instable easily and shakes, which results in a poor drilling effect is solved.

Description

technical field [0001] The invention belongs to the technical field of drilling rig equipment, and relates to a self-propelled double-column drilling vehicle. Background technique [0002] A drilling rig is generally composed of a chassis, a working mechanism, a drilling rig, a power unit, a transmission device, etc. The chassis is used to complete steering, braking, walking, etc., but the traditional chassis is directly used to support the bottom after stopping walking, so that the drilling rig During the drilling process, the chassis is easily unstable and shakes, resulting in poor drilling effect. Contents of the invention [0003] The invention proposes a self-propelled double-column drilling rig, which solves the above problems. [0004] Technical scheme of the present invention is realized like this: [0005] A self-propelled double-column drilling rig, including a chassis, a traveling crawler is arranged under the chassis, a column is arranged on the chassis, a gu...
