Hydraulic anchor drill is a kind of equipment used for anchor support operations in coal mines, tunnels and other projects. Its working principle is to provide power through the hydraulic system to drive the drill bit to rotate and perform drilling operations. It has the advantages of safety and explosion-proof, reasonable structure, convenient operation, high power, high efficiency, long service life and labor saving.
When using, you need to pay attention to the following points:
1. Safety inspection before drilling: Check that the operating switches of the main machine should be in the middle position (zero position); check whether the hydraulic oil pipe and water pipe are connected correctly; check the location of the designated drilling hole to ensure the stability of the roof and coal side. If necessary, temporary support should be used for the roof and coal side; check whether there are obstacles on the bottom plate of the designated drilling location.
2. Safety measures during drilling: When the drill rig rotates, you cannot touch the rotating drill rod with your hands or gloves, and one-handed operation is not allowed; the legs cannot be extended too quickly when drilling holes, otherwise the drill rod will be deformed and broken or the drill bit will be damaged; when the drill rig is suddenly loaded, the operating arm will swing in a certain direction, and the operator should maintain the correct standing position to prevent sprains; when the drill rig is used in the case of super-high roof, special safety measures should be formulated by the user unit.
Technical features:
1. Hydraulic drive: The hydraulic power system is used to provide strong torque and stable speed to ensure the drilling efficiency and quality in hard materials.
2. Portability: The design is lightweight, easy to carry and operate, and is particularly suitable for use in complex terrain or limited space.
3. Easy operation: It usually has a simple and intuitive control system, so operators can quickly get started and reduce training time.
4. Versatility: In addition to drilling and installing anchors, some models can also perform operations such as reaming and cleaning holes.
5. Safety: Equipped with a variety of safety protection devices, such as overload protection, emergency stop button, etc., to ensure safety during operation.
The emergence of hydraulic anchor drilling rigs has greatly improved the construction efficiency and safety of geotechnical engineering, and is one of the indispensable and important tools in modern engineering construction.
