Description
Technical field
This utility model relates to a kind of anti-strike electric cable test device, belongs to cable testing technology field.
Background technology
Anti-strike electric cable possesses good external shock resistance ability, is mainly used in the occasion that some mechanical shocks are strong, have weight to fall, for instance the field such as mining, hydraulic system.At present, anti-strike electric cable, when carrying out shock-testing, is repeatedly knocked by the hand-held weight of tester, then observes whether cable copper core exposes.This test mode not only labor intensive, and when copper core expose degree inconspicuous time, tester can not find sometimes.
Utility model content
This utility model is for the problem in background technology, it is proposed to a kind of anti-strike electric cable test device.
This utility model, for solving problem above, adopts the following technical scheme that
A kind of anti-strike electric cable test device, including base, cylinder, air cylinder support, buzzer, relief relay, and for controlling the electromagnetic valve of cylinder gas path on-off；Described base is provided with shock testing machine, binding post and power supply；Described cylinder is fixed on above shock testing machine by air cylinder support, and the direction of stretching out of cylinder piston rod is straight down, is provided with copper billet in the lower end of cylinder piston rod；The positive pole pin of described buzzer is connected with copper billet by wire, and the negative pin of buzzer is connected with power cathode；Described electromagnetic valve is connected with power supply by the action contact of relief relay.
Preferably, described power supply adopts direct-current switch power supply.
Preferably, described buzzer adopts direct-current piezoelectric type buzzer.
Technique effect:
1, anti-strike electric cable can be carried out repeated stock test by this utility model automatically, and when exposing occurs in cable copper core, device can pass through buzzer and remind tester in time, it is to avoid artificial erroneous judgement occur.
2, this utility model is rational in infrastructure, practical function, has good promotional value.

Detailed description of the invention
Below in conjunction with accompanying drawing the technical solution of the utility model done and introduces in further detail:
Structure of the present utility model is as it is shown in figure 1, include base 1, cylinder 5, air cylinder support 6, buzzer 7, relief relay, and is used for controlling the electromagnetic valve of cylinder 5 gas path on-off；Described base 1 is provided with shock testing machine 2, binding post 3 and power supply 4；Described cylinder 5 is fixed on above shock testing machine 2 by air cylinder support 6, and the direction of stretching out of cylinder 5 piston rod is straight down, is provided with copper billet 8 in the lower end of cylinder 5 piston rod；The positive pole pin of described buzzer 7 is connected with copper billet 8 by wire, and the negative pin of buzzer 7 is connected with power supply 4 negative pole；Described electromagnetic valve is connected with power supply 4 by the action contact of relief relay.
Described power supply 4 adopts direct-current switch power supply, for being powered to parts such as buzzer 7 and electromagnetic valves.
The direct-current piezoelectric type buzzer that described buzzer 7 adopts Jiangsu Xinhua Huayu Electronic Co., Ltd. model to be HYT-3105A, for carrying out sound prompting when cable copper core exposes.
Described cylinder 5 adopts FESTO company of Germany model to be the single-acting cylinder of ESNU-8-10-P-A, is used for promoting copper billet 8 that cable is impacted.
Described electromagnetic valve adopts the 2W040-10BH electromagnetic valve of Shanghai Hao Shi valve company limited.When solenoid valves, the valve of electromagnetic valve is opened, and cylinder 5 gas circuit is connected, and cylinder piston rod can be exited by air pressure；When electromagnetic valve power-off, the valve closing of electromagnetic valve, cylinder 5 gas circuit disconnects, and cylinder piston rod can be retracted.
Described relief relay adopts Taiwan ANLY company model to be the relief relay of AG4Q-HS, and when relief relay is energized, the action contact of relief relay time-interleaved can disconnect according to set and close.
During use, cable under test 9 is placed on shock testing machine 2 by tester, one end of cable under test is connected fixing with binding post 3 simultaneously, the other end of cable under test is accessed power supply 4 positive pole, afterwards, relief relay only need to be accessed power supply by tester, so that the action contact of relief relay alternately disconnects and closes: when the action contact of relief relay disconnects, electromagnetic valve disconnects with power supply, valve closing, cylinder 5 gas circuit disconnects, and cylinder piston rod is retracted, and copper billet 8 is pulled up (as shown in Figure 2)；When the action closing of contact of relief relay, electromagnetic valve and power on, valve is opened, and cylinder 5 gas circuit is connected, and cylinder piston rod stretches out, and is pushed down on rapidly by copper billet 8, so that cable under test 9 is carried out one-shot (as shown in Figure 3) by copper billet 8.So, as long as relief relay continues to be energized, cylinder will drive copper billet 8 repeatedly cable under test 9 to be impacted.When the overcoat of cable under test is broken through by copper billet 8, copper billet 8 can contact with the copper core of cable under test, so that the positive pole pin of buzzer 7 passes sequentially through copper billet 8 and connects with power supply 4 positive pole with cable copper core, the positive pole pin of buzzer and negative pin are sounded a buzzer after producing pressure reduction, to remind the copper core of tester's cable under test to expose.
