In the rail transportation system, in addition to the rails that people can see at a glance, those seemingly inconspicuous rail parts are also dedicated to the normal operation of the entire rail system, but few people can even notice them, even I don’t know what the names of these parts are.

Rail accessories include sleepers, connecting parts, track beds, anti-climbing equipment, rail braces, turnouts, fishtail bolts, etc. In addition to having comprehensive and reliable rail products, ZXSteel Group also produces various rail accessories that are very popular. With a high repurchase rate, it has been recognized by many users for many years.

In the construction of rail transit, the quality of fish bolts will affect the safety of the entire system, so you need to pay special attention to the purchase and installation. Let’s talk about the things that need to be paid attention to when anchoring the fishtail bolts.

1.  Clean up the nail holes so as not to affect the tightening effect, seal the bottom of the hole and use coarse sand to compact it

2.  Adjust the anchor frame to better control the position of the screw, fill it with solution but not too full

3.  The screw pile should be inserted vertically into the anchor frame and rotated left and right

4.  The square table of screw fasteners needs to be higher than the rail platform, about one millimeter higher than the steel belt fasteners, and about six millimeters higher than the plate fasteners

5.  After installation and solidification, clean up the overflowing solution.

In summary, it can be seen that the process of anchoring fishtail bolts is not complicated, but the operation must be carried out with a cautious attitude, so as to achieve the best installation effect and ensure the safe operation of the track system. In the daily maintenance work of railway workers, one of the tasks is to frequently check the loose fishtail bolts on the rails and fasten them in time to ensure the smooth passage of trains.
