Abrasion resistance detection device for fire hose

Abstract

The invention discloses an abrasion resistance detection device. The abrasion resistance detection device comprises a base, a stand column, a base, an expansion base, an expansion plate, a driving assembly, a receding groove, an installation plate, a sliding base, a support, a servo motor, a rotating shaft and a grinding wheel, wherein the sliding base is driven by a horizontal moving assembly toslide in the direction of the expansion base. The abrasion resistance detection device is advantaged in that a fire hose is sleeved on the expansion seat, an expansion plate is driven by the driving assembly to move towards the radial outer side of the expansion seat, further, an outer wall of the expansion plate abuts against the inner side of the fire hose, compared with the prior art that the fire hose is expanded in a water filling mode, working efficiency is improved to at least a certain degree, in addition, the expansion plate makes rigid contact with the fire hose, so the surface of the expansion plate is not prone to sinking in the abrasion resistance detection process, and abrasion resistance detection efficiency is improved.

Description

technical field [0001] The invention relates to the field of wear resistance detection equipment, in particular to a wear resistance detection device for fire hoses. Background technique [0002] Fire hose (fire hose) is a hose used to transport high-pressure water or foam and other flame-retardant liquids. A traditional fire hose is lined with rubber and wrapped with a linen braid on the outside. Advanced fire hoses are made of polymeric materials such as polyurethane. Both ends of the fire hose have metal connectors that can be connected to another hose to extend the distance or to a nozzle to increase the pressure of the liquid spray. Fire hoses are divided into two types: lined fire hoses and leaking fire hoses. Lined fire hoses include rubber fire hoses, TPU fire hoses, polyester glue-filled hoses, hemp plastic-coated hoses. According to the working pressure, it is divided into four categories: 0.8MPa, 1.0MPa, 1.3MPa and 1.6MPa. According to the diameter, it is div...

Problems solved by technology

[0004]In the prior art mentioned above, the fire hose is filled with water to expand into a columnar shape, and then the wear resistance test can be carried out. The water filling process is relatively slow, which leads to the detection efficiency In addition, after being filled with water, the fire hose still has a certain elastic deformation, which affects the accuracy of wear resistance detection.
