Air tightness testing device for fire extinguisher bottle bodies

Abstract

The invention discloses an air tightness testing device for fire extinguisher bottle bodies, which relates to the technical field of fire extinguisher testing. The air tightness testing device comprises a water storage assembly, a positioning assembly, a pressing assembly and a lifting assembly, wherein the water storage assembly is used for containing clear water required for detecting the air tightness of a plurality of fire extinguisher bottle bodies, and the water storage assembly comprises a water storage pool, a supporting plate and a Foma wheel; the positioning assemblies comprise a front group and a rear group, are used for automatically positioning the fire extinguisher bottle bodies in the front row and the rear row, and comprise positioning pipes, positioning plates, positioning blocks and rotating strips; the front pressing assembly and the rear pressing assembly are arranged and can be used for automatically pressing fire extinguisher bottle bodies in the front row and the rear row; each pressing assembly comprises a first fixing plate, a hydraulic cylinder, a hinge block, a hinge rod and a pressing pipe; the left lifting assembly group and the right lifting assembly group can be used for automatic lifting of the fire extinguisher bottle bodies in the front row and the rear row; and each lifting assembly comprises a mounting shaft, a driving motor, a sliding rod and a sliding block. In conclusion, the device has the advantages of being ingenious in design, reasonable in structure, convenient to detect and efficient.

Description

technical field [0001] The invention relates to the technical field of fire extinguisher testing, in particular to an airtightness testing device for a fire extinguisher bottle body. Background technique [0002] The production of fire extinguisher bottles usually goes through processes such as bottle body rolling, longitudinal seam welding, upper and lower heads, and bottle mouth valve seat welding. After the prototype of the bottle body is produced, in order to ensure product quality and later use, it is generally necessary to conduct an airtight test on the welded seam of the bottle body to detect whether there are trachoma in the welded seam. [0003] The existing detection method is to manually connect the threaded joint at the end of the gas source tube of the gas source device to the bottle mouth seat above the bottle body, then open the gas source valve to inflate and pressurize the container, and at the same time press the bottle body into the water to observe Whet...

AI Technical Summary

Problems solved by technology

Although this method can detect the airtightness of the fire extinguisher bottle, the whole process is manually operated, which makes the labor intensity of the workers high and the work efficiency low.
