A comprehensive detection instrument and detection method for the dynamic performance of subway screen doors

Abstract

A comprehensive detection instrument and detection method for the dynamic performance of a subway screen door of the present invention comprises a support rod assembly and a force rod assembly, and also includes a door clamping force host unit; the force rod assembly is placed horizontally and can move along the horizontal direction. When one end of the force bar assembly is squeezed and moved, the other end will be squeezed to the force-bearing end of the door clamp force host unit; the support bar assembly includes a left support assembly, a middle support assembly, a right support assembly and a support length adjustment assembly; the left support assembly 1. The right support assembly is respectively inserted into the two ends of the middle support assembly, and the adjustment rod one of the support length adjustment assembly is inserted into the fixed ring one of the right support assembly. The invention supports the fixed door frame of the shielded door through the door clamping force detection device, which can realize the door closing force and speed curve detection at any height position, and the installation is stable without manual support; in addition, after the support rod assembly is installed, it can ensure The entire unit is level and parallel to the running direction of the sliding door, requiring no additional adjustments.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a comprehensive detector and a detection method for the dynamic performance of a subway screen door. Background technique [0002] The subway screen door is an important safety link in rail transportation. Its function is to isolate the passenger waiting area and the train operation area from each other. With the rapid development of urban rail transit, the number of passengers has increased on a large scale. At the same time, casualties caused by screen doors are not uncommon. The closing force of the screen door is too large and the closing speed is too fast, which can easily cause people to be pinched. Detection of dynamic performance such as closing force and closing speed of screen doors is one of the effective measures to prevent accidents such as pinching. [0003] In the industry standard CJ / T236-2006 "Urban Rail Transit Platform Screen Doors", there are clear requirem...

Problems solved by technology

But this device has the following disadvantages: (1) the length adjustment of the cross bar depends on the cooperation of the card hole and the block, so the length of the cross bar can only be adjusted discretely; Manual support is required; (3) The impact of closing the door causes the value of the pressure sensor to increase instantaneously, resulting in inaccurate readings

However, this device has the following disadvantages: (1) It can only measure the closing force of the last stroke; (2) The height is fixed, and it can only measure the closing force of one position; (3) The index is limited by the structure of the stopper and the locking teeth , so that the measured value is based on the tooth spacing, and the test results are discrete values ​​with low precision

But this device has the following disadvantages: (1) the length of the whole device is adjusted by adjusting the length of the connecting bolt in the connecting sleeve, and the length adjustment is 100 cm, which is time-consuming and labor-intensive for this adjustment method; (2) the length of the screen door The pedal area is small, the tripod is not suitable for placement, and the manual measurement will affect the test result; (3) The reading value of the test result is only the deformation of the spring, and the closing force and kinetic energy of the door need to be calculated, which cannot be directly measured
