Embodiment Construction

[0012] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0013] As shown in the figure, the casing 9 of the present invention is provided with the input shaft 1 matched with the core drilling machine in the casing, and the driving gear 2 that slides up and down on the input shaft is sleeved. Sliding forward and reverse operation mechanism, when the driving gear slides to the bottom, the intermediate gear 4 set on the intermediate shaft 3 meshes with the driving gear and the counter gear 6 meshes with the driving gear when the driving gear slides to the top. The intermediate gear meshes with the forward gear 5, the forward gear and the reverse gear are set on the hollow shaft 7, the upper end of the hollow shaft is provided with a turntable 8 which rotates synchronously with it,...

Abstract

The invention relates to a mating rotary disc of a rock core drill. The mating rotary disc of the rock core drill comprises a shell, an input shaft and a driving gear, a clockwise and anticlockwise operating mechanism, an intermediate gear and an anticlockwise gear are arranged on one side of the driving gear, the clockwise and anticlockwise operating mechanism is used for the driving gear to vertically slide, the intermediate gear is meshed with the driving gear and sleeved with an intermediate shaft when the driving gear slides to the lower side, and the anticlockwise gear is meshed with the driving gear when the driving gear slides to the lower side. The intermediate gear is meshed with the clockwise gear, both the clockwise gear and the anticlockwise gear are sleeved with a hollow shaft, the upper end of the hollow shaft is provided with a rotary plate synchronously rotating with the hollow shaft, two shifters are arranged at the opposite corners of the rotary plate, a driving lever is fastened on the shifters, and the middle of the driving lever is provided with a square drill hole connected with a square drill pipe. Since the driving gear is matched with the clockwise and anticlockwise gears and drives the hollow shaft to drive the rotary plate via the same, the shifters and the driving lever on the shifters can rotate to finally drive the square drill pipe in the square drill hole in the middle of the driving lever to rotate, and large-torque output is realized.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to a rotary table for supporting a core drilling machine. Background technique [0002] The core drilling rig is a machine that uses the rotary action of the tubular drill bit to cut and grind the rock, and continuously drills deep to extract the core. It is generally used for drilling, and the existing core drilling rig has a small torque and cannot be used for drilling wells or foundation pile hole construction. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, and to provide a supporting rotary table for a core drilling machine that provides relatively large torsion. [0004] The present invention is achieved through the following technical solutions: [0005] A rotary table for a core drilling rig, a casing, an input shaft matched with the core drilling rig arranged in the cas...
