(1) When using the drilling rig to drill, the driver should be placed in the drilling position, so that the front end is against the rock, and the distribution should be careful to let the drilling rig move forward, so that the drill bit touches the rock; When opening the hole, first quietly let the drilling rig drive, when the drill rod is in place in the rock, it is allocated to the full open position.
(2) Before starting the drilling rig, check whether the charging pressure of the accumulator is normal; Check whether the scouring water pressure and the lubricating air pressure can be; Check whether there is sufficient lubricating oil in the lubricator, and whether the oil supply is appropriate; Check the reverse tendency of the oil pump motor. (3) If the drilling rig cannot open the hole smoothly, it should first assign the rock drill to retreat, and then let the rock drill move forward to open the hole from the beginning.
(4) When replacing the drill bit, the drill bit should be gently pressed against the rock, so that the motor of the drill can be reversed to complete the sensitive unloading head.
(5) The inspection of hydraulic components can only be prevented under the condition of pole cleaning, and after the connecting tissue is removed, it must be quickly plugged with the cleaning tightly matched plug. Before the repaired rock drill is used from scratch, it is necessary to circulate the hydraulic oil into the oil circuit to wash the components of the hydraulic system.
(6) The oil level and oil supply of the lubricator should be checked regularly; The gear with reverse structure is regularly filled with high-temperature grease; Check the oil level in the lubricating oil tank regularly and remove the dirt in the oil tank

  • Le treillis galvanisé est un type de grillage fabriqué à partir de fils d'acier inoxydable, qui ont été traités par galvanisation. Ce processus consiste à plonger le métal dans du zinc fondu, créant ainsi une couche protectrice qui prévient la rouille et la corrosion. Grâce à cette protection, le treillis galvanisé est idéal pour une utilisation en extérieur, où il est souvent exposé aux conditions climatiques.


  • Ένα από τα κύρια πλεονεκτήματα των μεταλλικών δικτύων είναι η αυξημένη αντοχή και ευελιξία που προσφέρουν. Σε περιπτώσεις σεισμών ή άλλων φυσικών καταστροφών, η ενίσχυση με μεταλλικά δίκτυα μπορεί να αποτρέψει την κατάρρευση των κατασκευών, προσφέροντας επιπλέον ασφάλεια στους κατοίκους. Το σκυρόδεμα, από μόνο του, είναι πολύ ισχυρό υπό συμπίεση, αλλά οι ρωγμές που μπορεί να δημιουργηθούν υπό εφελκυσμό μπορούν να θέσουν σε κίνδυνο την ακεραιότητά του. Με την προσθήκη μεταλλικών δικτύων, οι ικανότητες του σκυροδέματος βελτιώνονται σημαντικά.
