Bolt machine use matters needing attention

Precautions for use 1. Before drilling, it is necessary to ensure the stability of roof and coal gang and carry out safe operation. 2. Stop the bolt machine from being placed on the ground. As the drilling rig is flat on the ground, once the ventilation is misoperated, the air leg suddenly sticks out, which will cause accidents. 3, bolt machine drilling, stop wearing gloves to hold the drill pipe. 4. When the eye is opened, the drilling rig shall be stabilized to open the eye. 5, pneumatic bolting machine drilling, should be uniform speed plus atmospheric leg thrust, to prevent the formation of uneven thrust due to slow drilling speed, sticking, broken drill, chipping blade and other incidents. 6. Anchor Rig Return

Current Situation and Development Trend of Bolt Drilling Machine at Home and Abroad

Bolt support is a kind of roadway support method developed rapidly in recent years. By anchoring the anchor in the rock, the mechanical state of the surrounding rock itself is improved, and the supporting body and the surrounding rock itself form a unified structure that can bear the load, so as to improve the strength of the rock itself, prevent or delay the deformation of the surrounding rock, and effectively maintain the integrity of the surrounding rock and the shape of the roadway section. Anchor drilling rig is the key construction equipment in the construction of bolt support. The construction speed of bolt support and the quality of support depend largely on the anchor drill. Bolt support drilling rig technology is one of the key technologies that affect the speed, quality and efficiency of bolt support construction.

Brief Introduction of Anchor Rig

Bolt drilling rig is an indispensable tool in coal mine bolt support, and the development of bolt support requires a large number of bolt hole drilling equipment to ensure. Anchor drilling rig is also called anchor drilling rig in some places, which is a drilling tool in coal mine roadway bolt support work. It has outstanding advantages in improving the support effect, reducing the support cost, speeding up the speed of roadway, reducing the auxiliary transportation volume, reducing the labor intensity, and improving the utilization rate of roadway section. Anchor drilling rig is the key equipment of bolt support, which affects the quality of bolt support-the location, depth, accuracy of the hole and the installation quality of the bolt, and involves

Pneumatic Anchor Rig Use and Maintenance

With the development of bolt support technology, as the main mechanical equipment in the production process of bolt support, the bolt drilling rig has developed from the original single function, poor reliability, low technical content and poor safety to today's new drilling rig with high reliability, good safety and high degree of automation. At present, the use status of some mine bolting rigs is not very good. It is often that a new drilling rig needs to be repaired on the ground in less than two months, which seriously affects normal production. Whether the anchor drill can work normally and whether it can be eliminated accurately and timely after the failure is to improve the support effect, speed up the speed of roadway, reduce labor intensity, improve production efficiency and improve

Installation and operation of hydraulic bolter

The complete work of the hydraulic bolter has a lot to do with the correctness of its installation, so the installation before use must be especially careful and careful. When the location of the pump station and the host is determined. Connect the two oil inlet and return pipes between the oil pump outlet valve seat of the pump station and the oil inlet and return ports of the main engine. After confirming that the pipeline connection is correct, add about 120 liters of N46 anti-wear hydraulic oil into the oil tank, which can also be replaced by 30# mechanical oil. It is better to keep the liquid level at the middle and upper part of the oil mark. Hydraulic oil can also be added into the oil tank in advance according to the user's conditions. However, when using the hydraulic bolter, there are many small details that need to be closed.
