Accompanying drawing explanation
Fig. 1 is the structural representation of tower crane vertical ladder of the present invention traction anti-fall device;
Fig. 2 is the result of use figure of tower crane vertical ladder of the present invention traction anti-fall device;
Fig. 3 is the top view of tower crane vertical ladder of the present invention traction anti-fall device.
In figure: adsorbent equipment 1, movable pulley 2, sliding rail 3, rotating pin 4, carriage 5, spring hanging plate 6, spring hanging plate hole 7, spring 8, spring eye 9, closedown structure part 10, towing pad 11, hook ring 12, self-locking platen 13, locking stop step 14, waistband 15, pull rope 16.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further.
In the drawings, primarily of adsorbent equipment 1, movable pulley 2, sliding rail 3, rotating pin 4, carriage 5, spring hanging plate 6, spring hanging plate hole 7, spring 8, spring eye 9, closedown structure part 10, towing pad 11, hook ring 12, self-locking platen 13, locking, tower crane vertical ladder traction anti-fall device of the present invention stops that step 14, waistband 15, pull rope 16 form.
Described traction anti-fall device comprises sliding rail 3, carriage 5, closedown structure part 10, locking stop step 14; The chute arranged outside of described sliding rail 3 has row's locking to stop step 14, carriage 5 is provided with in the chute of sliding rail 3, described carriage 5 both sides are provided with movable pulley 2, and left and right, carriage about 5 two ends diagonal position is provided with groove, is provided with adsorbent equipment 1 in groove; Be provided with rotating pin 4 in the middle of described carriage 5, described closedown structure part 10 is connected with carriage 5 by rotating pin 4, and in the middle of described closedown structure part 10, upside is provided with spring eye 9; Described carriage 5 top is provided with spring hanging plate 6, and described spring hanging plate 6 arranged outside spring hanging plate hole 7, is provided with spring 8 between described spring hanging plate hole 7 and spring eye 9; Described closedown structure part 10 arranged outside has towing pad 11, and described towing pad 11 is provided with hook ring 12, described hook ring 12 is connected with waistband 15 below by pull rope 16; Self-locking platen 13 is fixedly connected with inside described closedown structure part 10.
Described adsorbent equipment 1 is magnet, and described magnet surface is provided with plastic insulating layer.
Described spring 8 is subject to downward tractive force more than the stretching that can deform during 19.6N.
Described closedown structure part 10 is made up of thickness 10mm steel plate.
Described adjacent locking stops that the distance between step 14 is 180mm.
When using tower crane vertical ladder of the present invention traction anti-fall device, first sliding rail 3 is arranged on the side of tower crane cat ladder by bolt, again waistband 15 tie up with it, waistband 15 moves up through pull rope 16 and drives closedown structure part 10 and carriage 5 to move upward.When moving downward, because spring 8 is subject to tractive force more than the stretching that just can deform during 19.6N, so when normally moving downward, waistband 15 moves downward through pull rope 16 and drives closedown structure part 10 and carriage 5 to move downward.When the health that meets accident drops suddenly; spring 8 is out of shape drop-down opening; closedown structure part 10 is rotated down; making self-locking platen 13 be stuck in locking stops on step 14; carriage 5 and closedown structure part 10 is made to stop moving downward; prevent tower crane operating personnel from stepping on empty tenesmus and causing danger, thus play a protective role in cat ladder process.
Tower crane vertical ladder traction anti-fall device structure of the present invention is simple; highly versatile; safe and reliable; adopt mechanical drive principle, safe effect is good, simply easy for installation on tower crane equipment vertical ladder; mounting cost can be reduced; protection tower crane operating personnel personal safety, prevents stepping on sky and falls, eliminate safe hidden trouble.
