An Air Leg Support Device for Rock Drilling Machines Convenient for Angle Adjustment

Abstract

The invention discloses a rock drill air-leg supporting device convenient to adjust an angle. The rock drill air-leg supporting device convenient to adjust the angle includes a rock drill main body, an upper connecting seat, a bottom rotating seat, a middle fixing rod, air-leg main bodies, installation pieces, first connecting shafts, connecting rods, a bottom installing plate, fixing claws and afixing bottom plate; a first fixing rod and a second fixing rod are arranged in the middle of the rock drill main body in a penetrating mode, and the top ends of the second fixing rod and the first fixing rod are correspondingly clamped with the a second limiting plate and a first limiting plate mutually, and the second limiting plate and the first limiting plate are further clamped with the two sides of the upper connecting seat mutually; and the bottom of a winding shaft is wound with a connecting wire, and a limiting block is installed at the top of the connecting wire. During the use, therock drill air-leg supporting device convenient to adjust the angle can not only facilitate the multi-angle adjustment work of the rock drill above the whole device, but also facilitate the angle fixing work after the adjustment work is completed, and the accurate drilling work of the rock drill is ensured.

Description

technical field [0001] The invention relates to the related field of technical rock drills, in particular to an air leg support device for rock drills that is convenient for angle adjustment. Background technique [0002] The rock drill air leg support device is an important accessory used to support the rock drill and has a propulsion function, so as to achieve an auxiliary device for fixing the rock drill. It is generally convenient to use the rock drill to drill horizontal or upturned positions. For rock work, the air leg type support device on the existing market has the following problems in the process of using; [0003] 1. In the process of fixing the rock drilling machine, the air leg support device on the existing market cannot perform multi-angle rotation of the rock drilling machine well, and cannot perform well after the position adjustment of the rock drilling machine is completed. The effect of the fixed position will cause the drilling angle of the rock drill...
