Light hydraulic drilling machine

Abstract

The invention provides a light hydraulic drilling machine. The light hydraulic drilling machine comprises a frame, a sliding frame and a supporting frame, a sliding frame guide sleeve is arranged above the frame, the sliding frame is connected with the frame in the mode that a sliding frame rear guide rail penetrates through the sliding frame guide sleeve, the lower side of the sliding frame is connected with a sliding frame front guide rail, an attachment plate penetrates through the sliding frame front guide rail to be fixed on the sliding frame, a drill box is arranged on the attachment plate, a long feeding oil cylinder is fixed to the inner side of the sliding frame, a short feeding oil cylinder is further arranged on the inner side of the sliding frame, a multiplication mechanism isarranged on the short feeding oil cylinder, an oil cylinder displacement sensor is arranged on the outer surface of the short feeding oil cylinder, and a pressure sensor is connected to the drill boxthrough a hydraulic rubber pipe. Compared with the prior art, the light hydraulic drilling machine has the following beneficial effects that the light hydraulic drilling machine is designed for various carrier characteristics of drilling machines in China, and can be applicable to various anchor rod (cable) machines, driving anchor machines, heading machines, drilling all-in-one machines and othersupporting equipment.

Description

technical field [0001] The invention is a light hydraulic drilling rig, which belongs to the field of drilling equipment. Background technique [0002] At present, the drilling rigs used in underground coal mines generally include dovetail directional drilling rigs and support columns and sliding frame separation cylindrical directional drilling rigs. Among them, the dovetail groove of the dovetail guide drilling machine is easy to wear, and the drilling machine works unstable after the wear; the cylindrical guide drilling machine with separate support column and carriage is bulky, heavy, and has strict requirements on the size of the carrier. At present, the above two drilling rigs have no self-feedback function. When the drilling rig is feeding, the feeding speed does not match the hardness of the roof rock. Personal safety hazard. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provid...
