  • the drilling tool is mounted in angular contact bearings, which are structurally relatively narrow, and for this reason are relatively less wear-resistant.
  • the base (the distance between the bearings) is 60 mm, which, to ensure sufficient rigidity of the shank attachment during its rotation, is relatively insufficient, which leads to runout of the shank, and as a result, to its rapid wear. For this reason, liner seals also wear out, which leads to a decrease in drilling rod purge efficiency, and the liner is destroyed when loads are exceeded, including in unforeseen extreme conditions.
  • the well-known technical solution of the device does not provide for the possibility of increasing the impact energy and torque of the drill rod (the torque in the known device is 720 Nm), it does not provide an increase in the service life of the perforator (tail) assemblies, bearings and replacing bearings with more powerful ones.

  • the work of the perforator is possible without pressurized gas under pressure, with no impact and blowing, which allows the use of a perforator in facilities where there is no compressed gas.
  • Torque to the shank of the perforator is transmitted from the hydraulic motor through a kinematic chain - hydraulic motor-coupling-shaft-shank.
  • Compressed gas purging of technological equipment (drill rod) during drilling is carried out through the purge channel (19) of the perforator shank.
  • the front of the punch is easily detachable.

Abstract

L'invention concerne un perforateur pour couvrir les trous de coulée de fours industriels, comprenant un corps (1) dans lequel se trouvent: une unité de répartition (3) dans laquelle se trouve un piston-percuteur (4), au moins deux tiges (2), un arbre (5) connecté d'un côté à un moteur hydraulique (6) via un embrayage (8) fixé sur deux paliers (7) et, de l'autre, à une queue (13), un tourillon (9), un insert (10) et deux paliers à roulements à deux pistes (12). La cavité de travail du perforateur est isolée par au moins cinq joints (14), et les extrémités du corps (1) du perforateur sont fermées d'un côté par un couvercle (15) et, de l'autre, par un flanc (16). En outre, la distance entre les centres des roulements (12) est d'au moins 163 mm.
