Splitting and propelling mechanism and drill jumbo containing same

Abstract

The invention provides a splitting and propelling mechanism. The splitting and propelling mechanism comprises a propelling guide rail, a sliding block tray, a splitting and installing base, a clampingdevice and a splitting machine, wherein the sliding block tray is arranged on the propelling guide rail in a sliding mode, the splitting and installing base and the clamping device are both arrangedon the sliding block tray, the clamping device is used for clamping a splitting machine body, and the splitting and installing base is used for fixing a connecting plate on the splitting machine. According to the splitting and propelling mechanism, the splitting machine body is clamped through the clamping device, the connecting plate of the splitting machine is fixed through the splitting installing base, the clamping device is used for clamping or loosening, so that the problems of too high rigidity, no movable displacement space and the like when the splitting machine pushes a hole can be solved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to a splitting propulsion mechanism and a drilling and splitting jumbo comprising the splitting propulsion mechanism. Background technique [0002] With the rapid development of high-speed railway and expressway traffic construction, the development of tunnel mechanical excavation construction equipment will be greatly promoted. The traditional tunnel construction is usually excavated by drilling and blasting, but due to vibration, noise restrictions, and explosive control, etc. Factors, and in the surrounding rock geology with high hardness level, the difficulty of blasting excavation is obviously increased, which makes the excavation by drilling and blasting method limited under special geological conditions and specific working conditions. As a supplement to the drilling and blasting method or an effective alternative to the excavation of short and medium-le...

AI Technical Summary

Problems solved by technology

However, since most of the current splitting construction uses manual hand-held splitters to split rocks, and manually inserts the splitter into the splitting hole, this method has the problem of low work efficiency

At the same time, for the airborne splitter, the cross shaft structure designed by the splitter comes with the purchased splitter, and most of them are only suitable for vertical splitting. The defect of this structure is that the splitter can swing arbitrarily and cannot maintain It is in a horizontal position with the propulsion beam. For the splitting of the hole on the face of the face, the splitting machine cannot be inserted into the hole vertically, and the splitting head of the splitting machine can only face downward freely. Cracked head stuck to the ground causing damage
