The technical scheme that the utility model solves the problem is as follows:
A kind of personnel's climbing protection device, is characterized in that:
It comprises two clamping plates and from the cable wire passed between clamping plate, is provided with at least one pair of locating shaft, limit shaft, clamp, positioning pulley and damper pulley between described two clamping plates,
Described clamp is arranged between two clamping plates by bearing pin, the described clamp both sides that are arranged on cable wire corresponding to limit shaft, the top of described clamp has the safety belt connecting hole of safety harness, the bottom of clamp is semicircle, described semicircle has gear part away from the side of cable wire, described bearing pin is in the semicircle eccentric part near cable wire one end, when clamp safety belt connecting hole one end upward time, the distance between clamp and limit shaft is a bit larger tham the diameter of cable wire; When clamp safety belt connecting hole one end turns to below, the gear part of clamp extrudes mutually with cable wire,
Described damper pulley and positioning pulley are positioned at the equal-height position of cable wire both sides, distance between damper pulley and positioning pulley is a bit larger tham the diameter of cable wire, the installing hole installing the damper pulley connecting axle place of damper pulley is the ellipse that major axis is in horizontal direction, damper pulley and damper pulley connecting axle have radially through screwed hole, set bolt penetrates in described screwed hole from the outside of damper pulley, installs and regulate bullet between described set bolt and damper pulley.
Be that the quantity of described locating shaft is at least a pair as further improving, be symmetricly set on the both sides of cable wire, the horizontal range between the locating shaft of described cable wire both sides is a bit larger tham the diameter of cable wire.
Further again, described positioning pulley and damper pulley are positioned at the below of limit shaft.
Further, described locating shaft is positioned at the top of limit shaft.
Operation principle of the present utility model is, cable wire is respectively between locating shaft, pass vertically through between limit shaft and clamp and between positioning pulley and damper pulley, when staff is when climbing, safety belt hauls safety belt connecting hole upwards, distance between clamp and limit shaft is a bit larger tham the diameter of cable wire, and it is up smoothly that safety belt hauls clamping plate; When staff surprisingly vertically falls; the upper end that safety rope hauls clamp overturns downwards; the semicircular gear part in clamp lower end contacts with cable wire and extrudes cable wire; now cable wire is clamped by clamp and limit shaft; stop the downslide of clamping plate; staff is protected, also by regulating the spacing between hold-down screw adjustment damping and cable wire in operation.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model can guarantee staff's normal operation, and effectively plays a protective role when vertically can fall when staff climbs.
2, rely on the measure arranging guard circle relative to prior art, the utility model personnel climbing protection device expands defencive function greatly.
3, the utility model applied range, both can be used as supplementary protection ship being provided with guard circle position, as work high above the ground region; Also may be used for the working environment cannot installing guard circle, personal protection and the extraordinary vertical personal protection enclosing well during as entered cargo hold.
