Description
Technical field
The present invention relates to a kind of personnel's climbing protection device, specifically refer to, be applicable to the protective device of boats and ships open deck and relevant climbing operating area.
Background technology
According to the requirement in AMSA (Australian Maritime Safety Authority) maritime affairs instruction the 32nd section of specification; in the above region of the open deck of ship; as mast; crane and other need operating area such as climbing operation etc. that emergent device for lowering persons should be set; general employing vertical ladder; and length need install guard circle additional more than the vertical ladder of 3m; circle hoop is with the setting being evenly and at intervals no more than 900mm; topmost the circle hoop at place should be connected with the upper end of railing, and the circle hoop located bottom should be positioned at more than the deck or platform be connected with this staircase platform and is not less than 2m but is not more than in the plane of 2.2m.Because this protective device is only arranged on the above region of open deck of ship usually, as mast, crane and other need to climb the region of operation.And the temporary protection when guard circle arranged can only provide the hypsokinesis of personnel's health, vertically falls for personnel can not play stop defencive function owing to stepping on sky landing.
According to the requirement of SOLAS (Convention on the Life Safety at Sea); only arrange the ladder access entering cargo hold; for the passage of the cargo tank of oil carrier and chemical tanker, SOLAS and IBC specification also but with the addition protective garment, the personal protection requirement of eye protector and breathing equipment.The not clear and definite the protection how personnel of tackling fall, also failed call arranges guard circle device.
In addition in the continuous climbing process of vertical passway for escaping, because the impact of vertically enclosing well cannot arrange this guard circle.For in the safeguard protection draft resolution 6.2.4.5 bar of lashing of container, MSC.1/Circ.1352 (stowage of goods and be solid code of safe practice) points out that the length of fixing vertical ladder is more than 3m, then need to arrange guard circle and prevent personnel from falling in cabin.
Can find out; because the guard circle arranged more than deck can only partly play personal protection effect; in cabin and other position can not installing such device personnel cannot be made to be effectively protected, and for personnel climb time vertically fall and can not play a protective role.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of personnel's climbing protection device, can play a protective role to the staff vertically dropped.
The technical scheme that the present invention 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 invention 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, beneficial effect of the present invention is:
1, the present invention 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 present invention staff's climbing protection device expands defencive function greatly.
3, applied range of the present invention, 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.
