Abstract

The invention relates to an ejection device for machining a drill stem. The ejection device comprises a supporting frame; a drill stem supporting base and a connection platform are arranged above the supporting frame, the drill stem supporting base comprises a fixed base and a movable base which are arranged in a spaced mode, the drill stem is placed between the fixed base and the movable base, and the upper surface of the movable base is lower than the upper surface of the connection platform; the movable base is movably installed on a bracket through a vertical guide rod, the bracket is fixedly connected with the supporting frame, and the guide rod is sleeved with a vertical spring arranged between the bracket and the movable base; an ejection mechanism is arranged below the drill stem and comprises an ejection hydraulic cylinder and an ejection block installed at the upper end of an piston rod of the ejection hydraulic cylinder, a cylinder body of the ejection hydraulic cylinder is fixedly connected with the supporting frame, and the upper surface of the ejection block is provided with an ejection bevel inclining in the output direction of the drill stem. The ejection device for machining the drill stem is simple in structure and reasonable in design; by means of an elastic lifting type supporting structure, the ejecting force can be reduced, moreover, the drill stem can be prevented from being output unstably, and the working reliability of the ejection device is high.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a processing device for drill pipes. Background technique [0002] The drill rod is a rod-shaped or tubular part that transmits power to the drill bit and enters the drill hole with the drill bit. It is an important part of the drilling machine. The drill pipe is made of light pipe and original steel pipe after many times of processing. After the drill pipe is processed, it is ejected and then exported to the connection platform. In the existing ejection device, the drill pipe needs to be completely ejected from the drill pipe support seat, so that the drill pipe can be smoothly rolled forward and exported, which requires a relatively large ejection force, and the ejection is not stable. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the applicant has conducted research and improvement to provide a ejector devic...
