Hydraulic anchor rod trolley

Abstract

The invention discloses a hydraulic anchor rod trolley, which comprises an engineering chassis, a working arm, an auxiliary arm, an anchor rod mechanism, an electrical system, a hydraulic system and acab. The anchor rod mechanism comprises a propulsion beam and a rock drill, an anchor rod bin is arranged on one side of the propulsion beam, a sliding guide rail, a caliper device, a rod grabbing device and a rod mounting device are arranged on the propulsion beam, the rod mounting device transfers a drill pipe or an anchor rod between the caliper device and the anchor rod bin, the rock drill isslidably connected with thesliding guide rail, and comprises a first sliding base, a power device, an output shaft and a connecting sleeve, the power device drives the output shaft to rotate, the output shaft is matched with one end of the connecting sleeve in a threaded mode, and the other end of the connecting sleeve is matched with the drill pipe or the anchor rod in a threaded mode; and the caliper device comprises a drill-rod clamping device and a drill-rod lifter which are arranged successively from front to rear. Switching between the anchor rod and drilling operation is realized on the basis of the engineering chassis, the sliding guide rail, a propulsion device and the like, and the multi-functionalization of the anchor rod trolley is realized.

Description

technical field [0001] The invention relates to the technical field of mining and tunnel engineering machinery, in particular to a hydraulic bolt trolley used for rock drilling and bolting. Background technique [0002] Bolting machine, also known as soil nailing machine, bolting rig or pneumatic impact machine, is mainly used for rock and soil bolting, roadbed, slope treatment, underground deep foundation pit support, tunnel surrounding rock stability, prevention of landslides and other disasters. Underground engineering support and high-rise building foundation treatment. It is also suitable for non-prestressed bolt support of deep foundation pit spray protection and slope soil nailing engineering. At this stage, rock drilling and bolt support construction in mines and tunnels are two different modes of operation. Existing hydraulic rock bolting jumbo is only used for bolting operation, and hydraulic rock drilling jumbo is only used for rock drilling operation, and the t...

AI Technical Summary

Problems solved by technology

The existing hydraulic rock bolting jumbo is only used for bolting operations, and the hydraulic rock drilling jumbo is only used for rock drilling operations, and the two cannot be interchanged or replaced

When the roadheader operation is completed, the support operator needs to move the rock bolter to the newly exposed empty roof area to install the drill pipe or anchor rod, and perform anchor rod and anchor cable support for the newly exposed roof and two sides After the support is completed, move the bolter to a safe place in the back, so that each cycle needs to dismantle and install the equipment, which is repeated many times per shift, which is very troublesome and time-consuming...
