Problems solved by technology

The telescopic movement of this utility model is mainly directly completed by the oil cylinder, and lacks more limiting parts. Therefore, although it has made some progress compared with the manually used rock bolt rig, to a certain extent, there is still a large swinging range of the drill pipe, and the drilling The accuracy of hole position positioning is not ideal, resulting in the poor quality of drilled anchor holes

Embodiment Construction

[0017] Shown in Fig. 1, Fig. 2, Fig. 3, the present invention comprises hydraulic motor, oil cylinder, support fixing mechanism, supporting mechanism, feeding mechanism and drilling mechanism. The rear bracket 6 is screwed together with the transition plate 14, the transition plate 14 is embedded in the connecting rotating body 8, the pressure ring 9 covers the transition plate 14 and is fixedly connected with the connecting rotating body 8 with bolts, after the above installation, the transition The disk 14 is free to rotate in the cavity formed between the pressure ring 9 and the coupling rotor 8 . Fix the bead 13 on the rear bracket 6 with screws, and insert the front bracket 1 into the chute formed by the bead 13 and the rear bracket 6 at the same time. After the above installation, the front bracket 1 and the rear bracket 6 should be able to move along the chute Slip fit. After one end of support guide post 15 passes through the guide hole on the rear support 6, it is sc...

Abstract

This invention relates to a rig using for the tunnel anchor below the coal mine. This invention resolves the problem of the existing technology. It supplies an airborne anchor pole rig that can locate more precise and assurance the quality of anchor hole. It includes hydraulic motors, tanks, fixation agencies, supporting agencies, feed and drilling sector. The front bracket inserts the sliding chute of back bracket. The supporting guide pole installed in the front bearer penetrates the guide hole of the back bracket. The guide plate connecting to feed tank is installed feed guide pole of the front bracket. The guiding hole on the hydraulic motor bed is installed on the feed guiding pole. Thus, all expanding components move along the guide pillar and the sliding chute, so the locating is more precise, the anchor hole has the high quality.

Description

Technical field [0001] The invention relates to a coal mine machine, in particular to a drilling rig used for anchoring and protection of an underground roadway in a coal mine. Background technique [0002] In roadway excavation, in order to prevent the roadway from collapsing, it is necessary to support the roof and side walls of the roadway. There are many support methods, but currently the most common method is bolt support. Nowadays, manual use of rock bolt rigs is very common. Due to the high labor intensity of manual single-machine operation, strong vibration of the drilling rig, large swing of the drill pipe, it is difficult to grasp the positioning of the drilling position, and it is easy to deviate, so that the quality of the drilled holes is not high. Replaced by airborne bolters. The Chinese patent with the notification number CN2232485 discloses a roadheader airborne bolter, which is mainly composed of a column oil cylinder, a compensation oil cylinder, a single...
