Abstract

The invention discloses a full hydraulic intelligent shaft umbrella drill which comprises a telescopic supporting column and a sleeve, wherein the sleeve is arranged outside the supporting column, andis driven by an angling cylinder to rotate around the axis of the supporting column; main arms are distributed in the circumferential direction of the sleeve in a ring array; the main arms are hingedto the sleeve; sliding frames are hinged to the other ends of the main arms; the full hydraulic intelligent shaft umbrella drill is also provided with a pitching cylinder and an overturning cylinder;and a supporting cylinder is controlled to ascend and descend and expand and retract by a control valve, when the device is adjusted to a proper position, three side supports are fully opened, are supported by the side wall of a shaft and are used for fixing the umbrella drill, and when three drill arms are enabled to be drilled downwards, the stability of the device meets the working requirement. The three drill arms adopt hydraulic control translation scheme. The lifting, pitching and left-right swinging of the drill arms and the propelling, rotating and impacting of a rock drill are controlled by a remote controller.

Description

Technical field: [0001] The invention relates to a fully hydraulic intelligent shaft umbrella drill. Background technique: [0002] At present, coal mine shafts are mainly constructed by drilling and blasting. The equipment used is mainly pneumatic rock drills, which use compressed air as power. During construction, high-pressure gas is introduced into the shaft through pipelines, and manual hand-held drilling rigs are used to drill holes. The efficiency is extremely low and the dust is relatively large. . The noise when the rock drill is started can reach 90 decibels, which seriously affects the physical and mental health of workers. With the continuous progress of rock drilling products. Some construction projects have begun to use pneumatic umbrella drills as equipment for shaft development. Pneumatic umbrella drills use a foldable mechanical structure to arrange the drill arm around the column, and the drill arm is driven by a linear oil cylinder or a swing rigid to ac...
