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. It relates to an automatic drill rod changing device for a tunnel anchor trolley. The automatic drill rod changing device for a tunnel anchor trolley includes a propulsion beam bracket, a propulsion drilling mechanism, a drill rod storehouse, and a drill rod storehouse lifting mechanism; The beam bracket is installed on the front end of the drill arm of the bolt trolley, and is mainly used to install the advancing drilling mechanism and the lifting mechanism of the drill rod warehouse; the advancing drilling mechanism is installed on the advancing beam bracket, mainly It has the functions of propulsion, drilling, and brazing. The propulsion drilling mechanism includes a rock drill, a propulsion cylinder, a middle tray, a brazing manipulator, a front end top plate, and a propulsion beam; The function of rod and unloading greatly improves the efficiency of deep hole drilling and reduces construction personnel. It has the advantages of high safety, low labor intensity and low construction cost, and realizes the effect of one machine with multiple functions.
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...
