I've been working on coal mining for over 20 years, and soft shielding is my old man. A lot of freshcombs asked me what it looked like and how it was structured, so i'd just sort out the pictures and notes of these years and tell the big guys. I'm sorrySoft cover standIt is the key guy who works under the wells to hold the ceiling, protect people and equipment, which is much more flexible than the old rigid stretcher and adjusts to the rise and fall of the coal layer。
Where's the soft cover frame
To be honest, most of the soft-covered images that can be found on the internet are the white-floor rendering in the product catalogue, looking at the rules, but far from the bottom of the well. I've got hundreds of live shots in my cell phone, with just installed, with a support frame going along with the coal layer, and with repairs to open up the interior structure. If you really want to see this thing, don't just stare at itHydraulic jacks, nodes, bottomsThose are the co-operations. The last time i filmed a series on the front of the 12th, stretching out from the rack to closing up, i saw 10 images in front of any cad drawings。
If you can't find a map, go over the technical manual for the major shelfers, and have a map of the structure with the label. But the best thing to do is to look down the well, or to find a teacher in the equipment department who borrows some old racks and taps the phone. The "sweetness" of the soft shield is reflected in itMultilink structureUp, several joints act independently and look like a folding bed, but gravity can hold up several tons of rock。
What about the soft shield
I've done this before. Tell you about the process. It is necessary to remove the coal machine, cut the power, confirm that the roof is stable, and then lay down from the bottom, and use the hydraulic roof to unload the stand, and to remove and sell each one of the jacks. The most important thing is that the drop points, the sales are so deep, they have to use a special tool, don't push it, they're all gone。
When you open the floor, you'll find three pieces of the main structure:The beam, the pole, the base seatIn the middle, it's tied up by four or five. In the poleHydraulic tankIt's the core, the cylinders are worn out or the seals are ageing, and the racks are leaking. The day-to-day repairs focused on these places, with flashlights and calibration gaps。
All right, all right, all right, all right, all right, all right, all right, all right. If you can't figure out which one to keep under the well, don't guess, ask the equipment section, or try it directly against the wrench, that's it. It's always safe to line up, and it's enough to get your hands on it。
