Mine air drill pipe Mine bolt drill pipe is based on the innovation and transformation of the wind drill pipe, is the replacement of the wind drill pipe products. It has the characteristics of wear-resistant, fast time-saving and labor-saving, and is more than a hundred times the life of the general air drill pipe, which is economical and practical. Mine bolt drill pipe is a new type of product. It can detect gas and water. It can be used alone or in combination. It can use new drill bits and old drill bits to prevent drill bits from falling off. Light weight, rapid connection, is an essential advanced tool for coal mine water exploration. Connecting the locator air drill pipe Connecting the locator anchor cable drill pipe, with a diameter of 19mm and an overall length of 1000mm, the thread form adopted for the rod body
Mine air drill pipe
Mine bolt drill pipe is reformed on the basis of wind drill pipe.It is an updated product of wind drill pipe. It has the characteristics of wear-resistant, fast time-saving and labor-saving, and is more than a hundred times the life of the general air drill pipe, which is economical and practical.
Mine bolt drill pipe is a new type of product. detectable gas, water exploration, can be single or combined, can use new drill bits and old drill bits, have the function of preventing drill bits from falling off. Light weight, rapid connection, is an essential advanced tool for coal mine water exploration.
Connecting the locator wind drill pipe
Connecting positioner anchor pipe, diameter19mm, the overall length is 1000mm, and the thread form of the rod body is rectangular thread.
Connecting the locator anchor cable drill pipe adopts advanced high-pressure forging production technology. The link form we adopt is male and female connection, and the rod body adopts55SiMnMo, 90CrMo high-quality hexagonal hollow alloy steel as raw materials, the product by high-pressure calcination, vacuum overall quenching and tempering heat treatment.
Connecting the locator anchor cable drill pipe is processed and formed by CNC automation equipment to ensure stable and reliable product quality. This type of wind drill pipe is mainly suitable for mine roadway support drilling.
In order to correctly use the anchor rod and ensure the normal service life, the following points must be paid attention:
1. According to the test comparison or the product recommend of our factory, the correct selection of drill rod type.
22. Ensure that the drill rod and the drill bit match well (the taper is consistent); if the taper of the drill rod is less than the taper of the drill bit, the tip is easy to break.
3For drilling hole depth> 2.0 m, recommend using a sleeve rod, that is, first use a short drill rod to open the hole, and then use a long drill rod to continue to extend the hole, in order to improve the service life of the drill rod (according to the hole depth, can use 2 sets of brazing or 3 sets of brazing).
4The hole should be stable, properly reduce the propulsion air volume, avoid the drill rod in the bending state of work, otherwise it will shorten the service life of the drill rod.
5In the process of drilling and withdrawal, try to avoid the bending force of the drill rod to improve the service life of the drill rod.
64. The air volume of the rock drill shall be adjusted according to the site conditions (rock conditions) to ensure the normal operation of rock drilling.
7For the rock condition of clamping, cross-shaped bit shall be used.
8The 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.
92. When normal use of ordinary drill rods is prone to batch early fracture, high-quality drill rods should be used instead; when high-quality drill rods are not used, large-size drill rods should be used instead, or wind pressure should be reduced.
102. The diameter of the drill rod shall match the power of the rock drill. If the power is large, the drill rod of large size shall be selected.
