Embodiment 1

[0047] Embodiment 1, refer to the attached Figure 5 , 6 .

[0048] The pipe seam anchor rod 501 is used, and the tail of the pipe seam anchor rod 501 is a pipe body with a gap, and the structure of the matching conversion joint 2-10 is: the anchor rod positioning head is the front cone 2-14, which is the same as the pipe seam anchor. The tail of the rod 501 is matched; the rear cylinder 2-15 of the conversion joint 2-10 is provided with a lever 2-11, and the lever 2-11 is connected with the plug-in slot 1-3 on the output end 1-1 of the rock drill match.

Embodiment 2

[0049] Embodiment 2, with reference to the attached Figure 7 , 8 .

[0050] Using the resin anchor rod 502, the structure of the matching conversion joint 2-10 is: the anchor rod positioning head is the front cylinder 2-16, the front cylinder 2-16 is provided with an inner hole 2-17, and the inner hole 2-17 and The tail of the resin bolt 502 is matched, and the rear end cylinder 2-15 of the conversion joint 2-10 is provided with a lever 2-11, and the lever 2-11 is connected with the plug slot 1 on the output end 1-1 of the rock drill. -3 to match.

Abstract

The invention relates to a joint conversion device and method for converting an anchor rod and a drill rod of a rock drill, and belongs to the technical field of tunnel drill jumbo. According to the technical scheme, a swing telescopic mechanism drives an adapter (2-10) to stretch and swing, an anchor rod positioning head is arranged at the front end of the adapter (2-10), and a deflector rod (2-11) is arranged at the rear end of the adapter (2-10); an anchor rod positioning head at the front end of the adapter (2-10) is matched with the tail structure of the anchor rod, and the anchor rod (5) is positioned on the adapter (2-10) by using different anchor rod positioning heads according to different anchor rods and is connected with the output end (1-1) of the rock drill through the adapter (2-10). The joint conversion device has the beneficial effects that the joint conversion device is used for automatically realizing conversion between the drill rod and the anchor rod, manual intervention is not needed, punching and anchor rod mounting are completed by adopting one rock drill, the space is saved, the working efficiency is improved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to a joint conversion device and method for converting a rock drill to an anchor rod and a drill rod, and belongs to the technical field of tunnel rock drilling trolleys. Background technique [0002] There are two operating methods for using a tunnel trolley (also known as a rock drilling rig): 1. Use two rock drills, one rock drill to install the drill rod, responsible for drilling holes, and the rock drill to leave after drilling the bolt hole, Another rock drill is used to install the bolt in the bolt hole; since the space for tunnel construction and underground mining is very narrow, using two rock drills to work alternately takes up a lot of space, is inconvenient to operate, and increases equipment investment. 2. After using a rock drill, after using the drill rod to complete the drilling, manually replace the drill rod on the rock drill with the bolt to complete the installation of the bolt; manually install the drill rod ...
