Description

Anchor rod propelling device Technical Field The invention belongs to the technical field of tunnel construction equipment, and particularly relates to an anchor rod propelling device. Background Along with the mechanized replacement of people proposed and gradually popularized in the field of engineering construction by China, the implementation of automatic people reduction regulations is carried out, the anchor rod trolley is important primary support equipment in the construction of railway and highway weak surrounding rock tunnels in China, the great advantage of the anchor rod trolley is gradually applied to the railway and highway tunnels, and meanwhile, the traditional manual installation is gradually replaced by the mechanized construction. At present, anchor rod trolleys at home and abroad adopt a screwing nut mode to enable anchor rods to generate prestress when anchor rods are installed, the friction resistance difference between nut threads and anchor rod threads and between nuts and backing plates is large due to the fact that the installation of the anchor rods is large when surrounding rocks are reinforced, if all anchor rods are installed one by one, a great amount of time and labor are wasted when the tension machines are required to be assembled and disassembled repeatedly, and engineering progress is seriously affected.
