The outer surface of the flange fixing piece is smooth and is unthreaded.
The bearing rope is a flexible wire, can be freely bent, and can limit different pipe diameters.
The tail end on the flange fixing piece is provided with two additional safety rope holes for additional fixing of the safety hook and the bearing object thereof outside the flange.
The middle part on the flange stationary blade is equipped with at least one bolt fixed orifices.
The general safety hook of input type water level gauge installation step as follows:
(1) Removing the fixing bolts of the flange of the water level gauge and the water level measuring pipeline, and lifting the water level gauge a little;
(2) An externally added safety rope hole at one end of the anti-falling device is fixed with a water level measuring pipeline through a rope, the other end of the anti-falling device penetrates through a loop line with the water level gauge as a allowance, so that a bearing rope can bear the weight of the water level gauge cable, and then the other end of the anti-falling device is placed at the symmetrical end of the flange;
(3) The water level gauge is dropped, and a flange fixing bolt passes through a bolt fixing hole of the anti-falling device to be fixed;
(4) The additional safety rope hole at the other end is fixed with the water level measuring pipeline through a rope.
The invention has the following characteristics:
1. the flexible connection reducing design can be suitable for the requirements of pipelines with different diameters.
2. Separated from the water level gauge body to avoid the asset waste of the integral replacement of the water level gauge.
3. The measuring loop and the measuring mode are not involved, so that the influence on the measuring precision of the existing equipment after installation is avoided.
The invention has the advantages and beneficial effects that:
the invention designs an anti-falling lock chain for flange plates with different diameters in order to improve the safety and reliability of an input type water level gauge. The processing mode and the installation condition of the reserved cable are designed by using the input type water level gauge, and the reserved cable can be installed and used under the condition that the water level gauge is not replaced. Through the additional installation of the invention, the water level gauge can bear most of the weight, on one hand, the water level gauge is protected from falling into a measuring pipeline, and on the other hand, the pulling force of the cable to the connecting terminal caused by cold contraction of the cable when the temperature changes is monitored.
