The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
As depicted in figs. 1 and 2, a kind of fall-preventing self-locking device comprises self-locking device body 1, and self-locking device body 1 comprises upper flat plate 10, following flat board 11, connects upper flat plate 10 and following dull and stereotyped 11 accepting groove 13 and the boss 12 that is connected with upper flat plate 10; Be provided with parallel and parallel each other 6, two first guide wheels 6 of first guide wheel of a pair of and self-locking device body 1 respectively by rivet 8 and upper flat plate 10 and dull and stereotyped 11 link to each other down at an end of self-locking device body 1 with wheel track; Be provided with a pair of and self-locking device body 1, first guide wheel 6 and parallel each other 5, two second guide wheels 5 of second guide wheel respectively by rivet 8 and upper flat plate 10 and dull and stereotyped 11 link to each other down at the other end of self-locking device body 1; Being provided with perpendicular drum-type the 3rd guide wheel 4, the three guide wheels 4 on the other end upper flat plate 10 of self-locking device body 1 is connected on the upper flat plate 10 by straight-neck rivet 7; Be provided with rotating pin 3 in the connecting hole of boss 12, rotating pin 3 is installed in spring 9 and latch 2 on the self-locking device body by the connecting hole of boss 12; One end of spring 9 is connected with boss 12, and the other end is connected with latch 2.On latch 2, be provided with lacing hole 14, as installing and using.
During work, fall-preventing self-locking device is stuck on the i-beam track, can slide up and down on i-beam track, on one's body the lacing hole of staff by latch is installed in fall-preventing self-locking device.I-beam track type falling proof device has kept the operation principle of lever braking, and locking is rapid, good reliability.When the operating personnel normally moved up and down, catching device moved with human body is smooth, when the operation personnel accidentally drop suddenly (foot) fall, catching device is under the effect of gravity, the lever phenomenon takes place be locked on the track, locking glides and is shifted is zero substantially, has reached suitable ideal effect.This kind catching device locking principle is a physical phenomenon, locking safety, reliable.Anti-fall main body in the catching device is the one material, has reduced complex mechanical construction, can not cause a hidden trouble owing to attaching parts go wrong.The catching device shell does not stress when anti-fall, and security reliability is high and do not have downslide, is convenient to regularly do safety test.
