Description
Technical field
This utility model belongs to test device technique field, is specifically related to a kind of pulling force automatic testing equipment.
Background technology
Power line tensile test is GB4706, a very important test in the product safety testing standard such as GB8898, GB4943, and the fixing device of test product power line is from pulling force at the terminals of wire, and insulation is from abrasion.Test process, first weighs the weight of product, and the test pulling force of utensil quality≤1kg is 30N, utensil quality>1kg, the test pulling force of<the test pulling force of 4kg is 60N, utensil quality>4kg is 100N；At distance Flexible Cord Fixing Device about 20mm, do a labelling when flexible cord stands the pulling force of correspondence, then, worst direction applies the pulling force of regulation, carries out altogether 25 times, the most persistently 1s.The displacement of last test labelling not can exceed that 2mm, does not has a equipment to can be used to do this test in the market, can only be by manually testing.Due to sample weight, adding the weight of counterweight and generally doing the get off muscle power of tester of a test is a kind of serious overdraw.Simultaneously because people is difficult to when drawing remain a constant speed, the pulling force causing line to bear is likely larger than standard-required value, on the time of 1s control be not especially good.
Utility model content
The purpose of this utility model is to provide a kind of pulling force automatic testing equipment, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of pulling force automatic testing equipment, including square steel support, support, trip bolt, electric magnet, counterweight, counterweight placing frame, control switch and power supply, described square steel support is provided with support, the two ends society of described support and trip bolt, the lower end of described square steel support is provided with electric magnet, the upper end of described electric magnet is provided with counterweight placing frame, the inside of described counterweight placing frame is provided with counterweight, one end of described electric magnet is connected with controlling switch by power line, the described switch that controls is connected with power supply by power line.
Preferably, between described support and square steel support, activity connects.
Preferably, described electric magnet is connected with controlling output switching terminal, and control switch input terminal is connected with power output end.
Technique effect of the present utility model and advantage: this pulling force automatic testing equipment is easy to install, greatly save manpower, and test pulling force and testing time more conform to standard-required, improves accuracy and the work efficiency of test.
Accompanying drawing explanation

In figure: 11, square steel support；12, support；13, trip bolt；14, electric magnet；15, counterweight；16, counterweight placing frame；17, control switch and 18, power supply.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullThis utility model provides a kind of pulling force automatic testing equipment as depicted in figs. 1 and 2，Including square steel support 11、Support 12、Trip bolt 13、Electric magnet 14、Counterweight 15、Counterweight placing frame 16、Control switch 17 and power supply 18，Square steel support 11 is provided with support 12，The two ends society of support 12 and trip bolt 13，The lower end of square steel support 11 is provided with electric magnet 14，The upper end of electric magnet 14 is provided with counterweight placing frame 16，The inside of counterweight placing frame 16 is provided with counterweight 15，One end of electric magnet 14 is connected with controlling switch 17 by power line，Control switch 17 to be connected with power supply 18 by power line，Support 12 is that activity connects between square steel support 11，Electric magnet 14 is connected with controlling switch 17 outfans，And control switch 17 inputs are connected with power supply 18 outfan，Controlling switch 17 is that portable time regulatable controls switch，
nullOperation principle: by the flexible cord of testing sample through removable mounting bracket 12，By close for 2 supports，Withstand Flexible Cord Fixing Device，Screw trip bolt 13，And sample body is fixed，Force value tests counterweight 15 corresponding for standard is put in counterweight placing frame 16,Stretch power line and with band, counterweight 15 be fixed on power line，The time of the On on regulation control switch 17 is 1s,The time of Off is 5S，Exchange turns direct current 24V power supply 18 be switched on civil power，Control switch 17 is switched on civil power，24V push-pull electromagnet 14，Can move down in the case of energising，Counterweight 15 is separated with counterweight placing frame 16，24V push-pull electromagnet 14，Can up move in the event of a power failure，Counterweight 15 contacts with counterweight placing frame 16，Control the enumerator on switch 17 and be shown as when 25 pulling out the power supply of portable time regulatable control switch 17 devices，This pulling force automatic testing equipment is easy to install，Greatly save manpower，Test pulling force and testing time more conform to standard-required，Improve accuracy and the work efficiency of test.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; although this utility model being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent; all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
