Abstract
The utility model relates to an intelligent self-triggered unloading device of a test load, comprising a framework, a lifting motor, a working platform, a photoelectric sensor, a delay circuit, a motor control circuit and a power supply, wherein the lifting motor is arranged on the framework and the lifting motor is provided with a liftable movable shaft; the working platform is connected and fixed at the top end of the movable shaft; the photoelectric sensor is mounted on the framework, and is used for detecting a swinging condition of a suspended weight on a power line; the photoelectric sensor is electrically connected with the delay circuit and the delay circuit is electrically connected with a motor control circuit; the delay circuit and the motor control circuit are respectively connected with the power supply; and after detecting that the suspended weight stops swinging, the photoelectric sensor sends a signal to the delay circuit, the delay circuit triggers the motor control circuit, and the motor control circuit controls the motor to lift and fall so as to support the suspended weight on the power line. According to the intelligent self-triggered unloading device disclosed by the utility model, the load of the power line can be detached in time, the test completely accords with the requirements of electric appliance safety standards, and the accuracy of a detected result is improved.
Description
Technical field
The utility model belongs to electric equipment products detection technique field, relates to a kind of electric equipment products power lead bending proving installation, specifically is a kind of after electric equipment products power lead cripping test finishes, can be with the power lead self-discharging device of loading.
Background technology
In the electric equipment products safety detection, usually need carry out the power lead cripping test to the power lead of the electric equipment products that move when the operate as normal.According to the products standards testing requirements; Power lead need add certain load (concrete grammar is that Suspension hanger weighs and extension is heavily swung on power lead) during test; Then by the crooked certain number of times of certain crooked speed, again the situation of power lead is detected after the off-test.This test should reach following requirement: (1) should not cause the short circuit between the lead; (2) should not cause the twisted wire silk fracture in any stranded conductor to surpass 10%; (3) should not cause lead to be thrown off from its connection terminal; (4) should not cause unclamping of conductive wire protection apparatus; (5) should not cause the damage of flexible cord or flexible cord protective device; The twisted wire that (6) should not cause rupturing penetrates insulation course and becomes the electric conductor that is prone to touch.
But in actual mechanical process,, often can not in time unload the load on the power lead after the off-test, and then influence is to the accurate judgement of testing result behind the power lead cripping test because this test period cycle is longer.Show in all at present electric equipment products testing agencies and the flexing test equipment of electric equipment products manufacturing enterprise, all do not have behind the power lead cripping test through relevant device the power lead load is unloaded timely and effectively according to investigation.
Above situation explanation designs a kind of power lead that can in time unload and loads, and makes test meet the security appliance standard-required fully, and the automatic discharge mechanism of highly versatile is very essential.Such device has great application potential in the detection of electric equipment products testing agency, electric equipment products manufacturing enterprise.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art; Provide a kind of simple and reasonable test load from triggering intelligent discharge mechanism; It can in time unload the power lead load, makes test meet the security appliance standard-required fully, improves the accuracy of testing result.
The technical scheme that provides according to the utility model: test load is characterized in that: comprise framework, lifting motor, workbench, photoelectric sensor delay circuit, circuit for controlling motor and power supply from triggering intelligent discharge mechanism; Lifting motor is installed on the framework, and lifting motor has a liftable shifting axle, and said workbench is fastened on the top of shifting axle, and photoelectric sensor is installed on the framework, and photoelectric sensor is used to detect hangs heavy swing situation on the power lead; Photoelectric sensor is electrically connected with delay circuit; Delay circuit is electrically connected with circuit for controlling motor; Delay circuit, circuit for controlling motor are electrically connected with power supply respectively, and photoelectric sensor sends signal and gives delay circuit when detecting extension and heavily stopping swinging, and delay circuit triggers circuit for controlling motor; Circuit for controlling motor control motor goes up and down, and is heavy with the extension of holding on the power lead.
As the further improvement of the utility model, said base of frame is provided with fine-tuning leg.
The utility model compared with prior art; Advantage is: the utility model is simple and reasonable, and low cost of manufacture adopts photoelectric sensor to come acquired signal and control lifting motor through delay circuit, circuit for controlling motor; Lifting motor drives workbench and rises automatically; Hold the load on the power lead, reach the self-discharging function of power lead load, control mode succinctly is prone to row; The utility model highly versatile can be fit to the automatic unloading requirement of dissimilar power lead flexing test equipments, warranty test result's accuracy.
