Drilling boom device of two-boom hydraulic rock bolt drilling carriage

Abstract

The invention relates to a drilling boom device of a two-boom hydraulic rock bolt drilling carriage. The drilling boom device comprises a drilling boom hinged support, a telescopic boom outer cylinder, a telescopic oil cylinder, a gap adjusting block, a telescopic boom, a drilling boom supporting oil cylinder, an adjusting oil cylinder, a feed mechanism, a drilling boom swing oil cylinder and a drilling boom fixing support, wherein the telescopic oil cylinder is arranged between the telescopic boom and the telescopic boom outer cylinder, the telescopic boom outer cylinder is in pivot connection with the drilling boom hinged support, and the drilling boom hinged support is fixed on the drilling boom fixing support through a pin shaft. The drilling boom supporting oil cylinder is respectively connected with the drilling boom hinged support and the telescopic boom outer cylinder through a pin shaft, the adjusting oil cylinder is respectively connected with the telescopic boom outer cylinder and the feed mechanism through a pin shaft, and the telescopic boom is arranged below the feed mechanism and connected with the feed mechanism through a pin shaft. The drilling boom device of the two-boom hydraulic rock bolt drilling carriage is compact in the whole-vehicle structure, reliable in strength, and capable of realizing the upper, the lower, the left and the right swing of the feed mechanism of the hydraulic rock bolt drilling carriage by the utilization of the connecting rod principle and stretching out and drawing back freely during construction.

Description

technical field [0001] The invention relates to a drilling arm device, in particular to a two-arm hydraulic rock bolt drilling vehicle drilling arm device for coal mine operation. The invention belongs to coal mine underground excavation equipment, and particularly relates to a two-arm hydraulic bolter drilling arm device which is suitable for large, medium and small coal mines and is required for continuous mining, continuous excavation, and comprehensive excavation construction of various roadways. Background technique [0002] At present, the main methods of tunneling in coal mines are continuous mining, continuous excavation, and fully mechanized excavation, and the support methods are combined support of bolts, anchor cables, joists, and anchor nets; Crawler-type liftable roof anchor rod and anchor cable construction drilling rig. [0003] Such as the Chinese Patent No.: 200720102731.2 disclosed crawler-type liftable roof anchor bolt anchor cable construction drilling ...

Problems solved by technology

[0003] Such as the Chinese Patent No.: 200720102731.2 disclosed crawler-type liftable roof anchor bolt anchor cable construction drilling rig, there are two drilling rig devices, one advance support, crawler-type walking mechanism; The drilling rig platform is installed on the frame; there is a coal pushing shovel plate at the front part of the crawler walking part under the drilling rig platform; a hydraulic cylinder type advance support is installed at the front end of the platform, and one side of the advance support is equipped with a The hydraulic drilling rig for roof anchor and anchor cable; the hydraulic drilling rig for roof anchor and anchor cable construction adopts double columns, and the slideways of the left and right moving parts are installed on the double columns, and the hydraulic drilling rig rotates left or right; The hydraulic drilling rig for cable construction is installed on the middle side of the drilling rig platform, or on the left side, or on the right side. On the slideway, the oil cylinder installed on the drilling rig platform pushes the drilling rig to move back and forth as a whole. The construction drilling rig uses the column lifting device, the beam slideway and the swinging device to complete the lifting, left and right movement and swing angle of the hydraulic rock bolter rig, so as to It meets the construction requirements, but the disadvantage of this construction drilling rig is that the hydraulic rock bolter can only construct upwards, leftwards or rightwards, and cannot construct forwards, and cannot adapt to the construction of gas discharge holes, gas prediction holes, Requirements for geological drilling and water exploration holes; technical personnel in the field are also constantly trying to solve this problem, but most of the equipment on the market is complex in structure, high in cost, and troublesome to disassemble and maintain when problems occur. , there is an urgent need for a new technical solution to solve this technical problem
