As corresponding safety measures such as personnel have safety belt and backup protection rope to be protected, ground staff has safe fence, safety caps.
But during staff climbs upper steel tower from ground, but lack corresponding security protection.Once staff is climbing
Accident occurs during stepping on to make a misstep or slip, extremely easy danger of falling.There are two types of solutions in work at present, first is that
Slide rail is set in the main material of climbing, installs anti-fall device, but this programme needs are all laid in every base shaft tower, at
This is very high and substantially increases workload.Second is that wearing disconnection-prevention gloves are climbed, but this method can only be realized
Both hands, which are grabbed, climbs nail and is climbed, and while being climbed need to allow on hand anti-dropping device be inserted in climb nail after carry out subsequent action again, this
The climbing time of staff is greatly extended, and usually climbing for proficiency main material is followed closely in one trick when climbing shaft tower with us
It is far from each other to climb mode.
Summary of the invention
To overcome the above deficiencies, the invention provides a kind of angle steel tower climbing for effectivelying prevent worker to fall is anti-
Protection unit.
The present invention overcomes the technical solution used by its technical problem to be:
A kind of angle steel tower climbing protective device, comprising:
Outer housing, the u-shaped structure in cross section；
Two clamping plates, are vertically arranged inside outer housing, and two clamping plates are parallel to each other；
It is horizontally spaced respectively on the inner wall of left and right two of outer housing to be provided with several otic placodes I；
Several otic placodes II, it is horizontally spaced to be set on clamping plate lateral surface；
Several connecting rods, described connecting rod one end are articulated and connected by pin shaft I and otic placode I, and the other end passes through pin shaft II and respective side
Otic placode II be articulated and connected；
One end of several extension springs, the extension spring is connected with clamping plate, and the other end is connected with outer housing, works as extension spring
In a free state, the spacing between two clamping plates is greater than the angle steel of angle steel tower or foot follows closely outer diameter；
The lower end of two inner walls in left and right of outer housing is horizontally installed with rubber block respectively, and the spacing of two rubber blocks is small
Outer diameter is followed closely in the angle steel or foot of angle steel tower；
The clamping plate is connected by rope with the body of worker.
The beneficial effects of the present invention are: when worker falls, since worker's body is connected by rope with clamping plate, clamping plate by
It using the inside side oscillation of connecting rod and stretches extension spring when downward pulling force, so that the spacing between two clamping plates becomes smaller, together
When rubber block stress deformation, angle steel or foot nail enter in outer housing, since two clamping plate spacing become smaller, thus until clamping plate
Step up to nail in angle steel or foot, prevent outer housing from falling, since two clamping plates make the therefore clamping generation of gradually relative motion
Frictional force is gradually increased, to also achieve buffering when worker falls.After worker steps on angle steel tower again, rope not by
Power, extension spring drive clamping plate to reset to dynamic realize of backswing, do not need to improve shaft tower on a large scale, both saved at
This, and improve work efficiency, the worker for being obtains most in the case where having no need to change oneself climbing posture and climbing speed
Effective protection, greatly improves the personal safety of staff.
