Embodiment
Below in conjunction with accompanying drawing, introduction is in further detail done to the technical solution of the utility model:
Structure of the present utility model as shown in Figure 1, comprises base 1, starting stave 4, second riser 5, motor 8, oval cam 9, electric machine support 10, the time relay 12, hummer, the guide rail 2 be located on base 1, the slide block 3 be slidably matched with guide rail 2 and the optoelectronic switch 11 for detecting slide block 3 position; Described starting stave 4 lower end is fixed on slide block 3, and starting stave 4 upper end is provided with the first connection terminal 6; Described second riser 5 lower end is fixed on base 1, and the second riser 5 upper end is provided with the second connection terminal 7; Described motor 8 is fixed between starting stave 4 and the second riser 5 by electric machine support 10, and motor 8 output shaft drives oval cam 9 to rotate; The cambered surface of described oval cam 9 acts on starting stave 4 side; The coil of the described time relay 12 is connected with power supply by the normally closed contact of optoelectronic switch 11; Described hummer is connected with power supply by the normally opened contact of the time relay 12.
The described time relay 12 adopts Shanghai Yue Zhong Electric Appliance Equipment Co., Ltd model to be the on-delay type time relay of DAA01C.When the coil of the time relay 12 arrives its setting value continuous conduction time, the normally opened contact of the time relay 12 can close.
Described optoelectronic switch 11 adopts Nanjing Man Jisi Electric Applicance Co., Ltd model to be the electric switch that diffuses of MJS-FS50-JK, whether arrive below optoelectronic switch 11 for detecting slide block: when bouncing block 5 slide block and not arriving below optoelectronic switch 11, the light beam that optoelectronic switch 11 is launched can not be reflected back, and the normally closed contact of optoelectronic switch 11 closes; When slide block arrives below optoelectronic switch 11, the light beam that optoelectronic switch 11 is launched can be reflected back by slide block 5, and the normally closed contact of optoelectronic switch 11 disconnects.
Described first connection terminal 6 and the second connection terminal 7 all adopt Taiwan Tian De company model to be the connection terminal of TBR-20, for being connected and fixed the end of spiral cable.
Described guide rail adopts STAF company model to be the line slideway of BGXH20BN, and described slide block adopts STAF company model to be the guide rail slide block of BGXH20BN-N-Z0.
During test, the two ends of spiral cable 13 to be measured are separately fixed on the first connection terminal 6 and the second connection terminal 7 by staff, afterwards, installation's power source is connected by staff, oval cam 9 is driven to rotate after motor 8 is energized, when the major axis of oval cam 9 is rotated to horizontal direction by vertical direction, starting stave 4 and slide block 3 promote to the direction away from the second riser 5 by the cambered surface of oval cam 9, slide block 3 leaves the below of optoelectronic switch 11, now, spiral cable 13 is in extended state (as shown in Figure 2), when the major axis of oval cam 9 is rotated to vertical direction by horizontal direction, if the restoring force of spiral cable is normal, starting stave 4 and slide block 3 can pull to the second riser 5 direction by spiral cable, and slide block 3 is pulled to the below of optoelectronic switch 11, and the normally closed contact of optoelectronic switch is disconnected (as shown in Figure 1).So, as long as the restoring force of spiral cable 13 is normal, starting stave 4 just ceaselessly can do horizontal reciprocating movement, slide block 3 all can arrive the below of optoelectronic switch 11 once at regular intervals, thus the normally closed contact of optoelectronic switch is disconnected once, the coil electrify time of the time relay 12 cannot be accumulated to its setting value, and the normally opened contact of the time relay 12 disconnects always.When the restoring force of spiral cable 13 occurs weak, slide block 3 cannot arrive the below (as shown in Figure 3) of optoelectronic switch 11, the normally closed contact of optoelectronic switch 11 can close always, the coil of the time relay 12 continues energising, when being accumulated to its setting value the conduction time of the time relay 12 coil, the normally opened contact of the time relay 12 closes, and hummer and power supply are connected and started to pipe, to remind staff's cable fault.
