Description

Technical Field

[0001] The utility model relates to the technical field of flameproof shell inspection, in particular to a shell finished product inspection platform. Background Art

[0002] Explosion-proof equipment is a commonly used equipment in places with explosion risks such as mines and chemical industries. It consists of an internal electrical core and a flameproof casing that isolates electrical components from external explosive media such as gas, smoke, and flammable materials. According to the standard, all equipment used in the coal mining field must be explosion-proof electrical equipment, and the flameproof casing should have sufficient mechanical strength. Therefore, after the flameproof casing is produced, the strength of the flameproof casing needs to be tested.

However, there is a lack of protective mechanism during the inspection. When the flameproof enclosure fails the inspection, it is easy to break and the generated fragments can easily cause harm to the inspectors. For this reason, we propose a finished shell inspection platform. Utility Model Content
