Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal simulation testing machine technology, and in particular to a door anti-fall device and system for a thermal simulation testing machine. Background Technology
[0002] Thermal simulation testing machines are among the most widely used equipment in the fields of high-temperature performance testing of metallic materials and simulation research of thermal processing in production sites. They are frequently used in scientific research practices and new material development in research institutions. Taking the Gleeble thermal simulation testing machine manufactured by DSI Corporation in the United States as an example, to meet various testing needs, the machine body is designed with an incline. It has front and rear doors. When loading samples or cleaning the machine, the operator needs to open either the front or rear door. These doors are supported by hydraulic support rods, and when erected, they are positioned directly above the operator's head, tilted approximately 30° towards the operator's standing direction. These two doors weigh about 10 kilograms. If the hydraulic support rods suddenly fail, these two doors will tilt and fall, striking the operator's head and causing fatal injury.
[0003] To prevent the aforementioned safety accidents, a door anti-fall device suitable for the Gleeble thermal simulation test machine has been designed. The purpose is to hook and lock the front and rear doors together, providing secondary protection and preventing the doors from falling. Utility Model Content
