Trigger firing device aging test platform

Abstract

A trigger firing device aging test platform comprises a test table. A testing table bracket is fixed to the bottom of the test table. The left end and the right end of the test table are each provided with a cylinder body fixing support for fixing a fire protection bazooka. A trigger firing device comprises a trigger and a reset handle, wherein a tension spring for making the trigger reset is arranged in the reset handle, and the fired trigger is kept in a to-be-fired state after the reset handle is bent. A slide groove is formed in the position, axially corresponding to the fire protection bazooka, of the test table. A rack slide block is arranged in the slide groove. The trigger firing device aging test platform further comprises a trigger testing device, a reset handle testing device and a motor driving device. One end of the trigger testing device makes contact with the trigger. The other end of the trigger testing device is connected with the rack slide block. One end of the reset handle testing device is connected with the reset handle. The other end of the reset handle testing device is fixed to the rack slide block. One end of the motor driving device is connected with the rack slide block. The other end of the motor driving device is connected with a motor shaft and used for driving the rack slide block to slide back and forth.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment detection and fire extinguishing, and in particular relates to an aging test platform of a trigger firing device. Background technique [0002] my country is a country with frequent fires. Every year, fires cause huge economic and environmental losses in our country. Fire bazookas have been more and more used in forest fires and high-rise fires due to their better remote fire extinguishing effects. Fire bazookas As the most important part, the trigger firing device of the fire bazooka must be subjected to an aging test before leaving the factory. Commonly used fire bazooka trigger firing devices include a trigger and a reset grip. After the trigger is pulled and fired, it is locked. After bending in place to reset the trigger spring, the trigger can continue to be pulled. Therefore, the quality of the trigger and the reset grip is very important for fire bazookas. However, most of th...

[0002] my country is a country with frequent fires. Every year, fires cause huge economic and environmental losses in our country. Fire bazookas have been more and more used in forest fires and high-rise fires due to their better remote fire extinguishing effects. Fire bazookas As the most important part, the trigger firing device of the fire bazooka must be subjected to an aging test before leaving the factory. Commonly used fire bazooka trigger firing devices include a trigger and a reset grip. After the trigger is pulled and fired, it is locked. After bending in place to reset the trigger spring, the trigger can continue to be pulled. Therefore, the quality of the trigger and the reset grip is very important for fire bazookas. However, most of the aging detection of fire bazooka trigger firing devices is done manually by testers. The firing of the trigger and the bending and reset of the reset grip, due to the limitations of the time and strength of human operation during the manual test, make the number of cycles of the aging test of the trigger firing device of the fire bazooka less, the test results are not objective enough, and the test process is not enough Stablize
