Problems solved by technology

This can lead to the often necessary replacement of the drill pipe after opening the taphole more difficult
The drill rod can become jammed in the drill rod receptacle due to the plastic deformation of the rear end of the drill rod in the drill rod receptacle, so that the drill rod cannot be easily removed from the drill rod receptacle without problems

Embodiment Construction

[0035] figure 1 A side view of the tapping machine 10 on the partly shown blast furnace wall 11 is shown. The tapping machine 10 has a foot 12 and a positioning device 13 for moving and positioning a carriage 14 arranged thereon, which has a drill rod 15 and a drilling and percussion mechanism 16 . The drill rod 15 is inserted into the drill rod receptacle 17 of the drilling and percussion mechanism 16 and can be moved back and forth along the carriage 14 in the direction of the blast furnace wall 11 by the longitudinal movement of the drilling and percussion mechanism. Furthermore, fastening means 19 are provided on the front end 18 of the bracket 14 , which securely fasten the bracket 14 to the holder 20 on the blast furnace wall 11 . Thus, in particular precise tapping hole drilling can be performed. Furthermore, a clamping device 21 with a lever drive 22 is arranged on the front end 18 , wherein the lever drive 22 is connected via a drive shaft 23 to an actuating cylinde...

Abstract

Holding device (27) comprises a gripping device, which is arranged on a mounting. A tap hole drilling machine (10) exhibits a mounting (11) having a movably arranged drill- and hammer mechanism (16). The drill- and hammer mechanism comprises a drill rod receptacle (17) for connecting the drill rod. The gripping device acts relative to drill rod receptacle for holding the drill rod. The drill rod is firmly fixed on the mounting by the gripping device. An independent claim is also included for removing the drill rod from drill rod receptacle of tap hole drilling machine, comprising moving the drill rod receptacle to the gripping device such that the drill rod is removed from the drill rod receptacle.

Description

technical field [0001] The invention relates to a holding device for a drilling rod of a tapping machine and a method for removing a drilling rod from a drilling rod receptacle of a tapping machine. Background technique [0002] Tappers are sufficiently known from the prior art and are basically used for opening channels for the melt by drilling holes in the blast furnace wall. Known tapping machines are basically formed by a carriage with a drilling and striking mechanism arranged thereon. The drilling and percussion mechanism has a drill rod holder for connecting a drill rod several meters long. The carriage is made of the sliding carriage type and is mounted eg rotatably or pivotably so that said carriage can be moved upstream of the taphole of the blast furnace into a position provided for drilling. For drilling, the front end of the bracket is usually fixed firmly to the blast furnace by means of fastening devices as well. Accordingly, relatively high feed forces can...
