Subway platform screen door dynamic performance comprehensive detector and detection method

Abstract

The invention discloses a subway platform screen door dynamic performance comprehensive detector and a detection method. The detector comprises a supporting rod assembly and a stress rod assembly and further comprises a door clamping force host unit. The stress rod assembly is horizontally arranged and can move in the horizontal direction, and when one end of the stress rod assembly is extruded to move, the other end of the stress rod assembly can be extruded to the stress end of the door clamping force host unit. The supporting rod assembly comprises a left supporting assembly, a middle supporting assembly, a right supporting assembly and a supporting length adjusting assembly. The left supporting assembly and the right supporting assembly are inserted into the two ends of the middle supporting assembly respectively, and a first adjusting rod of the supporting length adjusting assembly is inserted into a first fixing ring of the right supporting assembly. The door clamping force detection device is supported on the fixed door frame of the shielding door, door closing force and speed curve detection at any height position can be achieved, the installation is stable, and manual supporting is not needed; besides, after the supporting rod assembly is installed, the levelness of the whole device can be guaranteed, the supporting rod assembly is parallel to the running direction of the sliding door, and extra adjustment is not needed.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a comprehensive detection instrument and detection method for the dynamic performance of a subway screen door. Background technique [0002] The subway screen door is an important safety link of rail transit. Its function is to isolate the passenger waiting area from the train operation area, and correspond to the train. It is a continuous barrier that can open and close the sliding door with multi-level control. 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 excessive closing force and fast closing speed of the screen doors can easily cause people to be pinched. The detection of dynamic properties such as closing force and closing speed of the screen door is one of the effective measures to prevent accidents such as pinching. [0003] In the in...

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
