Abstract

The invention relates to a general drilling stand for a light geological drilling rig, which comprises an upright, a slide sleeve device, a base, an upper chain wheel, a lower chain wheel, a chain, an inclined support, a gear reduction device and a general interface backplate, wherein the slide sleeve device is arranged on the upright in a sleeving manner, the upper chain wheel is fixed on the gear reduction device, the gear reduction device is fixed at the upper end of the upright, the lower chain wheel is fixed at the lower end of the upright through a chain wheel shaft, the upper end of the chain bypasses the upper chain wheel, the lower end of the chain bypasses the lower chain wheel, and the chain is connected with the slide sleeve device; one end of the inclined support is fixed at the upper end of the upright and the other end of the inclined support is fixed on the base; and one side of the general interface backplate is connected with the slide sleeve device. According to the invention, the general interface backplate can be connected with various kinds of drilling rig power heads through a flange, and the drilling stand is stably supported with the lightest structure weight due to the adoption of the structure design of the single upright and the inclined support.

Description

technical field [0001] The invention relates to a novel universal drill stand for a portable drilling rig, in particular to a universal drill stand for a portable geological drilling rig. Background technique [0002] The drill frame is an important part of the drilling rig. The stability, lifting capacity and structural weight of the drill frame directly determine the overall performance of the drilling rig. [0003] Currently, most of the drill stands on the market are part of a specific drilling rig and are not universal. And, the existing drill stands on the market are such as anchor column type, column type, disc type, portal type drill stand. The structural weights of these drill stands are all above 100kg, which cannot meet the needs of portable drilling rigs. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a universal drilling frame for portable geological drilling rigs, which overcomes the defects in t...
