A subway safety screen door strength detection device

Abstract

The invention discloses a subway safety screen door strength detection device, which comprises a bottom plate and a top plate, an earthquake simulation device is arranged on the top of the bottom plate, and the earthquake simulation device includes two electric telescopic rods placed in parallel, and the two electric telescopic rods One end of the rod is welded with a second fixing plate, and the outer walls of one side of the two second fixing plates are provided with adjustment holes, and the inner walls of the adjustment holes are fixed with rolling rollers distributed equidistantly by bolts. The top of the bottom plate is welded with a fixing seat. The invention can drive the drive plate to vibrate in irregular horizontal and vertical directions, well simulate the vibration of the transverse wave and vertical wave of the earthquake, can change the vibration amplitude, and improve the adjustable performance of the device. Cooperate with the screen door body when blowing air, so that the wind passes between the screen door body and the sliding plate, increases the wind speed, reduces the load of the blower under the condition of satisfying the wind pressure, and saves electric energy.

Description

Technical field [0001] The present invention relates to the field of shielding door detection, and more particularly to a subway safety shield door strength detecting device. Background technique [0002] At present, the main structure of the subway shielding door requires 30 years of design life. After installation is completed, there is no significant structural adjustment and maintenance during normal operation. When the tunnel wind pressure generated during the train will bring a wind pressure load on the shield door, the screen passengers may also generate impact loads on the shield door structure. Many times the earthquake will also affect the mask door, and the horizontal wave and vertical Waves cannot simulate, need to detect the strength of the mask door, provide a reliable design basis. [0003] Afterwards, the Chinese patent authorization number is a patent of CN206362640U, which discloses a urban rail transit station block screen detecting a crowd extrusion loading de...

AI Technical Summary

Problems solved by technology

The above-mentioned patents have the following deficiencies: it is impossible to simulate the wind pressure on the screen door when the subway enters and exits the station due to an earthquake, the extrusion of the crowd, the strength of the impact force and the superimposed pressure of its own weight, and it is impossible to flexibly adjust the strength of this force size

And above-mentioned patent can not solve this type of problem, therefore, needs a kind of subway safety screen door intensity detection device badly
