When preparing Schindler elevator shaft, we should pay attention to check whether the shaft has been cleared of garbage and determine the position of scaffolding so that it will not affect the plumb line and guide rail. When erecting scaffolding frames, we should add a crossbar at regular intervals. Pay attention to some debugging when hanging plumb lines in the hoistway, that is, locate the formwork at the upper part of the hoistway, then put down the vertical lines that locate the car, counterweight guide rail and door, and fix the vertical line position on the lower formwork after setting the vertical line position. When handling guide rails, it should also be noted that guide rails are generally provided in bundles and lifted by forklift or crane. When operating the guide rail in these two ways, the two lifting points must be one meter apart. In order to ensure the contact quality, the machined ends of the guide rail and the connecting plate must be thoroughly cleaned.
When adjusting the guide rail, pay attention to using measuring tools and fixtures to adjust the guide rail. The back of the bracket can be padded for easy adjustment. When installing the guide bracket, there are also some debugging, that is, the bracket drills holes at each fixed point on the wall and fixes it with expansion bolts or chemical fixatives, nuts and washers. When the bracket is fixed at the beam splitting, it should be welded directly. If the shaft wall is uneven, a washer can be used. The guide rail must be installed at a right angle, and the sign of the right angle is that the pointer matches the mark engraved on the adjustment gauge.
In order to obtain ideal riding quality, the deviation from the center should be less than 0.5 mm If the pointer deviates from the center, it must be adjusted according to the original vertical line. When adjusting the guide rails, the contact points of each guide rail must be strictly checked. If the contact points have prominent edges, they must be leveled. After the guide rail is adjusted, the guide rail bracket shall not be welded again.
The above is the debugging problem of Schindler elevator that Bian Xiao talked about today. Bian Xiao talked about it in detail. I believe everyone has a preliminary understanding. We can see that we must be careful when debugging Schindler elevator. Details are important. Don't overlook the details. Only in this way can we successfully debug Schindler elevator.
