Description

Technical Field

[0001] This utility model belongs to the field of drilling equipment technology, specifically relating to a rod support device for supporting the middle of an anchor bolt. Background Technology

[0002] In the propulsion systems of rock drilling equipment such as engineering drilling rigs, rock drilling jumbos, and anchor bolt jumbos, the anchor bolts used in the drilling device are slender rods. During drilling, they are prone to bending deformation under the action of thrust, which leads to a decrease in hole straightness, a decrease in drilling efficiency, an increase in drill bit consumption, and an acceleration of drilling rig wear. In order to maintain the stability of the anchor bolt, a front-end support rod is usually fixed at the end of the propulsion beam, and a sliding support rod is installed in the middle of the end of the propulsion beam, so as to prevent the anchor bolt from bending and deforming in the middle part due to rotation and axial pressure.

[0003] When drilling with a drilling device, although the central support rod can slide and reset under the action of gravity, when drilling horizontally or vertically downwards, because there is no drive mechanism on the feed beam that matches the central support rod, the central support rod cannot move synchronously with the drilling device after drilling is completed, thus preventing the central support rod from resetting. This reduces the drilling efficiency of the drilling device. Utility Model Content
