The specific embodiment
Technological means and the effect thereof for further setting forth the utility model, taked, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
Consult Fig. 1 to Fig. 6, the utility model provides a kind of this shaft tower high altitude anti-falling dropping control device for achieving the above object, comprise from top to bottom and by bolt 0, be fixed on upper bracket 1, anti-sway ring 2 and the undersetting 3 on shaft tower successively, between described upper bracket 1, anti-sway ring 2 and undersetting 3, by steel strand wires 4, connect, described steel strand wires 4 are for having etch-proof stainless steel steel strand wires or aluminium Baogang steel strand wires.
Described upper bracket 1 and undersetting 3 are respectively by upper end and the lower end of the clamping fixed described steel strand wires 4 of screw bolt-type compression bonded line 13.
Described anti-sway ring 2 comprises first and second anti-fork 21 and 22, on described the first anti-fork 21, be provided with the first groove 211 of left opening, on the second anti-fork 22, be provided with the second groove 221 of right opening, described steel strand wires are through first and second groove 211 and 221.
Wherein anti-sway ring 2 is mainly used among a small circle, fixing steel strand wires 4, prevents that vibration on a large scale appears in these steel strand wires 4 when the upper and lower shaft tower of personnel, affects upper and lower personnel's safety or the difficulty of increase operation.This anti-sway ring 2 can also be for being arranged on the shaft tower position with certain angle, for turning in addition.
The steel strand wires 4 that fix with screw bolt-type jointing clamp 13 are provided with the screw rod 41 of sealing in the position of the end of a thread, rainwater can not beaten in the end of a thread position of steel strand wires 4 can effectively place corrosion like this.
On described steel strand wires 4, be also provided with catching device 5, this catching device 5 comprises that aviation aluminium main body 51, rotation are fixed on cam-type brake lever 52, the two blade saw radula sheets 54 that are connected with cam-type brake lever 52 by spring 53 in aviation aluminium main body 51 and are connected to the protection rope 55 on cam-type brake lever 52.
Described catching device 5 also comprises rotation cover 56, and when described rotation cover 56 is opened, these steel strand wires 4 can be arranged between described two blade saw radula sheets 54; After described swivelling cover 56 is screwed closure, this two blade saws radula sheet 54 can not come off from steel strand wires 4.
Concrete setting is that these steel strand wires are between two blade saw radula sheets 54.
This catching device 5 when staff upwards climbs, is fastened at staff's protection with it 55 other ends of restricting and is tied up on cam-type brake lever 52 after installing, and is provided with specially the hole for being protection rope 55 on this cam-type brake lever 52.When personnel swash, cam-type brake lever 52 upwards rotates under the drive of protection rope 55, and this sawtooth tongue piece 54 will unclamp the steel strand wires 4 that interlock compresses, thereby this catching device 5 moves upward together along with staff's rising.When this staff drops because of work mistake; protection rope 55 produces downward pulling force; make this cam-type brake lever 52 move to downward maximum angle place; now this cam-type brake lever 52 is oppressed sawtooth tongue pieces 54; sawtooth tongue piece 54 steps up steel strand wires 4; utilize frictional force resistance personnel tenesmus, thereby reach the effect of fall arrest.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection domain of the utility model claim.
