Drill rods belong to the series of rock drilling tools, also known as drill rods

Introduction

Details

Drill rods belong to the series of rock drilling tools, also known as drill rods.
Material: Pneumatic drill rod body is made of 55SiMnMo, 90CrMo hexagonal hollow alloy steel as raw materials.
Specifications: The common specifications of pneumatic drill rods are B19/B22/B25, etc.
Product Usage
Application fields: Pneumatic drill rods are widely used in mine roadway support drilling, mine rock drilling, coal mine rock roadway, bridge tunnel excavation and other engineering construction.
Application Field:
Product Advantage
1: The pneumatic drill rod has the characteristics of rapid connection, adaptability to any angle, convenience and speed.
2: The anchor cable drill pipe has strong bending resistance, strong durability, easy disassembly and assembly, and convenient operation.
3: The rock-drilling air drill pipe is very wear-resistant (100 times that of the traditional drill pipe) and can be used for coal, water and gas exploration.
4: The slag discharge is fast, which saves time and effort, and is cost-effective compared with similar products.
The high-pressure forging process used for the pneumatic drill rod, and the vacuum overall quenching and tempering heat treatment. The application of CNC automation equipment to process and shape ensures stable and reliable product quality
Maintenance Instructions
In order to use the anchor rod and drill rod correctly and ensure normal service life, the following points must be paid attention to:
1. According to the test comparison or the product recommendation of our factory, choose the correct drill rod type.
2. The company’s tapered drill products have the “G” trademark on the rod body and collar plate. From the end of the rod body, the “G” opening of the collar plate is concave to the right, the rod body is a convex mark, and the excellent drill mark is “G ︱” , “G ‖”, the general drill marks are “G”, “G-1″. In order to track product quality, there is also a batch number on the drill body.
3. It should be ensured that the drill rod and the drill bit cooperate well (consistent taper); if the taper of the drill rod is smaller than the taper of the drill bit, the tip will be easily broken.
4. For the drilling hole depth > 2.0 meters, it is recommended to use a sleeve rod, that is, first use a short drill rod to open the hole, and then use a long drill rod to continue drilling to improve the service life of the drill rod (according to the depth of the hole, it can be used 2 sockets or 3 sockets).
5. The opening should be stable, and the propelling air volume should be appropriately reduced to prevent the drill rod from working in a bent state, otherwise the service life of the drill rod will be shortened.
6. During the drilling and withdrawal process, try to avoid the bending force of the drill rod to improve the service life of the drill rod.
7. The air volume of the rock drill should be adjusted according to the site conditions (rock conditions) to ensure the normal operation of the rock drilling.
8. For the rock condition of the stuck drill, a cross-shaped drill bit should be used.
9. The user shall not arbitrarily change the structure of the drill rod or use it after reprocessing, so as not to affect the normal service life of the drill rod.
10. When the ordinary drill rod is prone to early batch fracture in normal use, the excellent drill should be replaced; when the excellent drill is not used, the large-sized drill rod should be replaced, or the wind pressure should be reduced.
11. The diameter of the drill rod body should match the power of the rock drill, and if the power is large, a large-sized drill rod should be used.
