Abstract

The invention belongs to the technical field of automatic drill rod replacement of tunnel anchor rod trolleys, and mainly relates to an automatic drill rod replacing device of a tunnel anchor rod trolley. The automatic drill rod replacing device of the tunnel anchor rod trolley comprises a propelling beam bracket, a propelling drilling mechanism, a drill rod bin and a drill rod bin lifting mechanism. The propelling beam bracket is installed at the front end of a drill arm of the anchor rod trolley and mainly used for installing the propelling drilling mechanism and the drill rod bin lifting mechanism. The propelling drilling mechanism is installed on the propelling beam bracket, mainly has propelling, drilling and drill rod clamping functions, and comprises a rock drill, a propelling oil cylinder, a middle tray, a drill rod grabbing manipulator, a front-end top tray and a propelling beam. The automatic drill rod replacing device of the tunnel anchor rod trolley has the functions of automatically installing and disassembling the drill rod in the deep hole drilling process, the deep hole drilling efficiency is greatly improved, the number of constructors is reduced, the automatic drill rod replacing device has the advantages of being high in safety, low in labor intensity, low in construction cost and the like, and the effect that one machine has multiple purposes is achieved.

Description

technical field [0001] The invention belongs to the technical field of automatic drill rod replacement of a tunnel anchor trolley, and mainly relates to an automatic drill rod replacement device for a tunnel anchor trolley. Background technique [0002] In recent years, with the continuous improvement of the automation of tunnel construction machinery, multifunctional tunnel bolt trolleys have become a development trend, which can also greatly improve the economy of tunnel construction. Previously, the method of drilling deep holes in tunnels mainly used special equipment for deep hole drilling or manually added drill rods to the anchor trolley to complete the deep hole excavation. This method is economical and inefficient. 1. The labor intensity of personnel is high, which increases the tunnel construction cost. Contents of the invention [0003] In order to solve this existing drawback, the present invention proposes an automatic drill rod changing device for a tunnel b...
