Single hydraulic prop is a new type of environmental protection support equipment, which can be used together with metal hinged roof beam, mainly used for supporting roof of gun working face and general mining working face, and can also be used as point column or other temporary support alone.
The single hydraulic prop is characterized by low comprehensive cost, small volume, reliable support, high support height and convenient use and maintenance. So what are the key points when installing?
Main points of single hydraulic prop installation:
Supporting device 1. This is to make a homework, two people with one will individual hydraulic prop drunbility, bearing on the substance, and took hold of his hand, hands up column move fluid injection gun, liquid injection gun into valve mouth before, we should use liquid injection gun to flush valve mouth, while the other one is to check the roof, the roof beam, please hold on to prevent roof beam falls to the people. Before lifting the column, the top beam should be adjusted so that it is perpendicular to the coal wall, and ensure that it is well connected to the top.
2. During the installation process, the three-valve nozzle should be pointed toward the goaf area.
3. After the use of the nozzle, it should be hung on the handlebars of the single hydraulic prop. It is forbidden to put the nozzle on the bottom plate.
4. It is strictly forbidden to use liquid leakage or invalid single hydraulic prop, and it is strictly forbidden to use improper way to handle liquid leakage three-use valve.
5. When using the single hydraulic prop, the miner should hold the palm up to prevent the roof from falling and damaging the arm during the lifting process.
6. The single hydraulic prop must reach the specified initial support force before the injection can be stopped.
