Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, 2, the utility model provides a kind of free safety belt, and it comprises mechanism of twisting rope 1, retaining mechanism 2 and safety belt 3.Wherein: mechanism of twisting rope 1 has housing 11, be provided with rope-winding shaft 12 in described housing 11, described rope-winding shaft 12 is connected with clockwork spring 13, one end of described clockwork spring 13 is connected with described rope-winding shaft 12, its other end is connected with described housing 11, and described rope-winding shaft 12 is wound with safety rope 14; Retaining mechanism 2 has ratchet 21, described ratchet 21 is set on described rope-winding shaft 12, and described ratchet 21 is axially convexly equipped with drag ring 211, and described rope-winding shaft 12 is connected with multiple linkage block 22, described linkage block 22 contacts with described drag ring 211, and the lower end of described ratchet 21 is provided with ratchet 23; Safety belt 3 is connected to one end that described safety rope 14 stretches out described housing 11.
Specifically, the upper end of the housing 11 of mechanism of twisting rope 1 is connected with upper hook 4 by steel wire rope 15, and on this, housing 11 can be suspended on works by hook 4.In the utility model, housing 11 is made up of two panels half housing make-up, is provided with a rope-winding shaft 12 in housing 11, and the two ends of rope-winding shaft 12 are connected with two panels half housing respectively.This rope-winding shaft 12 is connected with clockwork spring 13, and the outer end of clockwork spring 13 is connected with the inwall of housing 11, and rope-winding shaft 12 is also wound with safety rope 14, and safety rope 14 is stretched out from the bottom of housing 11 and is connected with safety belt 3 with draw ring 51 by lower draw-bar 5.
Retaining mechanism 2 is arranged in housing 11, the ratchet 21 of retaining mechanism 2 is set on rope-winding shaft 12, ratchet 21 is convexly equipped with drag ring 211 along its axial direction, rope-winding shaft 12 is connected with polylith linkage block 22, in the utility model, on rope-winding shaft 12, radial symmetric is connected with two pieces of linkage blocks 22, and this linkage block 22 is substantially in fan-shaped, its one end is fixedly connected on rope-winding shaft 12, contacts outside its other end with drag ring 211 madial wall of ratchet 21.Ratchet 23 is positioned at the lower end of ratchet 21, and it is connected on housing 11, and when ratchet 21 rotates, ratchet 21 is meshed with ratchet 23, thus ratchet 21 will stop the rotation under effect established by the card of ratchet 23.
Further, housing 11 is connected with acoustic control mechanism 16, this acoustic control mechanism 16 has telescopic electromagnet 161, and under the state that electromagnet 161 stretches out acoustic control mechanism 16, this electromagnet 161 offsets with ratchet 23.This acoustic control mechanism 16 is made up of battery, the sound control circuit plate be electrically connected with battery and the electromagnet 161 that is connected with sound control circuit plate, after sound control circuit plate receives outside voice signal, control electromagnet 161 is stretched out acoustic control mechanism 16 by it, make one end contact of electromagnet 161 on ratchet 23, this acoustic control mechanism 16 can the position of fixed pawl 23 further, makes ratchet 23 establish more firm with the card of ratchet 21.
Safety belt 3 in use, is tied up to the waist of workman by this free safety belt, and this free safety belt is suspended on works by upper hook 4 by workman, and operative is convenient, need not change hitch point.Workman, under the effect of self gravitation, safety rope 14 slowly can be pulled out in housing 11, thus workman according to the length of the control safety rope 14 of need of work freedom and flexibility, and can be able to move freely; This safety rope 14 is in the process of pull-out, rope-winding shaft 12 is with safety rope 14 together slow circumvolve, the clockwork spring 13 now rope-winding shaft 12 connected is tightened, when safety rope 14 pull out long need regain time, workman only no longer need apply any pulling force to safety rope 14, and this safety rope 14 can be wrapped on rope-winding shaft 12 in automatic retracted to housing 11 under the effect of clockwork spring 13.In the utility model, safety rope 14 is in pull-out process slowly, because the speed ratio of rope-winding shaft 12 is slower, the frictional force be now connected between linkage block 22 on rope-winding shaft 12 and the drag ring 211 of ratchet 21 is not enough to make linkage block 22 drive ratchet 21 to rotate, ratchet 21 relative volume reel for rope 12 transfixion.
When there is suddenly the situation of landing in workman in work high above the ground, safety rope 14 can drive rope-winding shaft 12 to rotate fast, the linkage block 22 be now connected on rope-winding shaft 12 will with rope-winding shaft 12 fast rotational, the outside of linkage block 22 and drag ring 211 madial wall of ratchet 21 produce larger frictional force instantaneously, and together rotate with rope-winding shaft 12 under making the frictional force effect of ratchet 21 between linkage block 22 and drag ring 211, ratchet 21 will block with ratchet 23 after rotation to be established, ratchet 21 is stopped the rotation under the effect of ratchet 23, thus effectively control the rotation of rope-winding shaft 12, safety rope 14 is made to stop pull-out housing 11, the available protecting life security of workman.
Free safety belt of the present utility model, workman can the length of control safety rope 14 of freedom and flexibility, and can move freely, and operative is convenient and flexibly; The retaining mechanism 2 of this free safety belt; during the landing situation that can happen suddenly in workman's work high above the ground; the linkage block 22 of retaining mechanism 2 is made to drive ratchet 21 to rotate; block and establish to make to be positioned at ratchet 23 below ratchet 21 and ratchet 21 and limit the rotation of ratchet 21; and effectively control the rotation of rope-winding shaft 12; prevent safety rope 14 further pull-out housing 11, the available protecting life security of workman.
The foregoing is only several embodiment of the present utility model, those skilled in the art can carry out various change or modification to the utility model embodiment according to content disclosed in application documents and not depart from spirit and scope of the present utility model.
