Smoke machine strap bearing capacity testing device and testing method

Abstract

The invention discloses a smoke machine strap bearing capacity testing device and a testing method. The smoke machine strap bearing capacity testing device comprises a base and is characterized in that the base is fixedly connected to a lower fixing plate, the upper surface of the lower fixing plate is vertically connected to a guide column and a ball screw, the top ends of the guide column and the ball screw are connected to an upper fixing plate, a movable cross beam is arranged between the upper fixing plate and the lower fixing plate, and the movable cross beam is connected with the guide column and the ball screw; the upper part of the movable cross beam is provided with a stepping motor, the stepping motor is connected with a transmission device, the transmission device drives the movable cross beam to rise or fall, and the bottom part of the movable cross beam is connected to a tension sensor; a stay wire displacement sensor I is arranged between the movable cross beam and the lower fixing plate, the lower fixing plate is further connected to a stay wire displacement sensor II, and a stay wire end of the stay wire displacement sensor II is connected to a weight bracket. The smoke machine strap bearing capacity testing device is high in automation degree, low in labor intensity, convenient for observing changes of smoke machine straps, simple in structure and convenient to operate, and ensures high test precision, thereby effectively checking the quality of smoke machine strap components.

Description

Technical field [0001] The invention relates to a plant protection mechanical test device, in particular to an indoor load-bearing test device and a test method for checking the back strap of a fog machine. Background technique [0002] Fog machines, such as portable pulse fog machines, are in close contact with the human body during use. In the normal working state of the fog machine, the chemical tank is filled with chemical pesticides, the fuel tank is filled with gasoline, and the fog machine nozzle and protective cover work at a high temperature. If the fog machine strap breaks during use, it will cause serious harm to the human body. It may even be life-threatening and pollute the environment at the same time, so the quality of the back strap components of the haze machine is particularly important. According to the requirements of the standard, the back strap of the fog machine needs to be subjected to a load test. During the test, one end of the strap is hung on a suppo...

AI Technical Summary

Problems solved by technology

At present, there is no automatic loading and unloading of the strap of the fog machine and automatic measurement of the length of the strap of the fog machine in China.
