Abstract

The invention relates to a stretching-drawing system device for a two-arm hydraulic anchor rod drill rig. The stretching-drawing system device is characterized by comprising a stretching-drawing machine bracket, a high-pressure valve, a pressure gauge, a filter, a supercharger and hydraulic hoses, wherein a high-pressure valve opening A and a high-pressure valve opening B are respectively formed in the high-pressure valve; a filter opening A and a filter opening B are formed in the filter; the hydraulic hoses comprise a hydraulic hose I, a hydraulic hose II, a hydraulic hose III and a hydraulic hose IV; the hydraulic hose I is connected with the filter opening A; one end of the hydraulic hose IV is connected with the filter opening B; the other end of the hydraulic hose IV is connected with the supercharger; the hydraulic hose II is connected with the high-pressure valve opening A; the hydraulic hose III is connected with the high-pressure valve opening B. The overall technical scheme is ingenious and practical in design, reasonable in layout and convenient to operate; the limited space is fully utilized; the advancement and the mechanization degree of the drill rig are further improved.

Description

technical field [0001] The invention relates to an anchor cable tensioning device, in particular to a tensioning system device for a two-arm hydraulic rock bolt drilling rig. [0002] place. Background technique [0003] In the past, the coal industry in my country used wood to support the shed-style support, and this old-fashioned support method often caused landslide accidents. The Chinese people have carefully designed the anchor net support method used in the industry, which greatly reduces potential safety hazards. Previous anchor net support needs several kinds of equipment to complete, such as single hydraulic or pneumatic bolter, hand-held or outrigger side bolter, manual, electric or pneumatic anchor cable tensioning machine and ladder . The existing equipment or ladders have the following technical problems; 1) The existing hydraulic drilling rigs on the market can only meet the anchoring installation of the anchor bolt hole and the anchor bolt anchor cable on ...
