Gantry type mining hydraulic drill carriage

Abstract

The invention discloses a gantry type mining hydraulic drill carriage. The gantry type mining hydraulic drill carriage comprises a gantry support, a front drilling machine, a rear drilling machine, a hydraulic station and two parallel crawler traveling mechanisms, wherein traveling motors are both arranged on the two crawler traveling mechanisms, the gantry support is composed of two supporting legs and a platform, the lower ends of the two supporting legs are arranged on the two crawler traveling mechanisms, the platform is horizontally fixed to the upper ends of the two supporting legs, the hydraulic station is arranged on the platform, the front drilling machine and the rear drilling machine are used for drilling a roadway roof and are the same in structure, and a cavity for allowing a reversed loader for transporting coal to pass through is formed between the two supporting legs of the gantry support and the platform. According to the gantry type mining hydraulic drill carriage, due to the fact that the space allowing the coal mine reversed loader to pass through is formed between the two supporting legs in the gantry and the platform, the hydraulic drill carriage can cross the reversed loader to conduct drilling operation, and the technical problem that the hydraulic drill carriage and the reversed loader cannot work in the same position area of a roadway is solved.

Description

technical field [0001] The present invention relates to a gantry type mining hydraulic drilling rig, more specifically, to a gantry type mining hydraulic drilling rig. Background technique [0002] In the mining process of coal mines, it is first necessary to excavate the roadway. In the process of roadway excavation, the roadway with a certain width is firstly excavated by the roadheader, and then the roof and side walls of the roadway are supported. At the same time, the roadway roof needs to be implemented. Advance pre-splitting means splitting the roof of the roadway from the roof of the coal mining area. In the process of splitting, energy-concentrated blasting is usually used to achieve it. The method is to drill a series of drill holes (commonly known as blastholes) at equal intervals on both sides of the top wall of the roadway, and then insert holes with directional blasting function into the drill holes. The detonator is used to isolate the roof of the roadway fro...

Problems solved by technology

However, due to the cross operation in the process of roadway excavation, the roadheader is at the front, and the coal mine excavated by the roadheader needs to be transported out by a belt loader. It is also located at the back of the roadheader. In this way, during the drilling operation of the hydraulic drilling rig, it is necessary to drill across the transfer machine, which will cause the existing hydraulic drilling rig to be unable to reach the side of the roadway, resulting in inability to Do normal drilling
