Abstract
A safety catch device of a boat scaffold is hanged on the outer side of a cantilever beam. Two clamps are connected with the body of the device symmetrically via an eccentric pin shaft, and the position of the clamp jaw between the two clamps is provided with an inner side vertical rod of the scaffold. The two clamps are capable of swaying around the pin shaft for leading the clamp jaw to fasten or loosen the vertical rod. Two draw rods are connected with the two sides of the two clamps via hinge pins, and the two draw rods are provided with shoulder girdles which are provided with retainer pliers, and a compression spring and a spring seat are arranged under the retainer pliers. The lower ends of the two draw rods are connected with a cross bar via screw bolts, and the center of the cross bar is connected with a connecting rod which is connected with the lift hook of a lifting apparatus. When a wire cable is broken or a hoist is unhooked, the safety catch device of a boat scaffold is utilized, even if the scaffold is disconnected with the wire cable which is connected with the lifting apparatus or the hoist is unhooked, because of weight loss, the clamp jaw of the two clamps holds the inner side vertical rod firmly, thereby the falling accident of the scaffold can not happen.
Description
Affiliated technical field
The utility model relates to the safety dropping prevent mechanism of scaffold.
Background technology
Scaffold is the common equipment of building operations, and boat scaffold is in lifting process, and the steel cable that scaffold is connected with jacking equipment disconnects, and perhaps cucurbit is broken off relations, and can cause the falling accident of scaffold.Before this, safety dropping prevent mechanism also is not set on scaffold.
The utility model content
The purpose of this utility model is the safety dropping prevent mechanism that a kind of boat scaffold is provided in order to address the above problem, even the steel cable that scaffold is connected with jacking equipment disconnects, perhaps cucurbit is broken off relations, and also can not cause the falling accident of scaffold.
The technical scheme that its technical problem that solves the utility model adopts is: fix a semi girder on the floor plates face, there is the extension arm of frame construction in this mechanism, is suspended on the outside of semi girder.Locking member is made up of two clamps, two pull bars, two compression springs and spring base, cross bar, and two clamps are connected on the body of this mechanism with the bearing pin of off-centre symmetrically, are the inboard vertical rod of scaffold on the middle jaw position of two clamps.Two clamps can be swung around bearing pin, to form jaw to the clamping of vertical rod or unclamp.Two pull bars are connected the both sides of two clamps by hinge pin, on two pull bars omoplate are arranged, and there is back-up ring at the place at omoplate, and compression spring and spring base are arranged below back-up ring.Connect a cross bar in the lower end of two pull bars by bolt, be connected with connecting rod in the central authorities of cross bar, the suspension hook of connecting rod and jacking equipment is connected.When operate as normal, under the gravity of jacking equipment, two pull bars are pulled down by cross bar, its pulling force and compression spring balance each other, and the jaw of two clamps unclamps; Steel cable disconnects or cucurbit is broken off relations when taking place, and tightly embraces the inboard vertical rod of scaffold because of losing jaw that weight makes two clamps, prevents to fall.
Effective effect of the present utility model is, uses the safety dropping prevent mechanism of boat scaffold of the present utility model, even the steel cable that scaffold is connected with jacking equipment disconnects, perhaps cucurbit is broken off relations, and also can not cause the falling accident of scaffold.
Description of drawings
Figure is the structural representation of the safety dropping prevent mechanism of boat scaffold of the present utility model.1-connecting rod among the figure, the 2-cross bar, the 3-spring base, 4-compresses spring, the 5-back-up ring, the 6--pull bar, the 7--hinge pin, the 8-clamp, the 9--bearing pin, the 10--vertical rod, 11--hangs arm, 12--semi girder.
Specific implementation method
Fix a semi girder (12) on the floor plates face, there is the extension arm (11) of frame construction in this mechanism, is suspended on the outside of semi girder (12).Locking member is made up of two clamps (8), two pull bars (6), two compression springs (4) and spring base (3), cross bar (2), two clamps (8) use eccentric bearing pin (9) to be connected on the body of this mechanism symmetrically, are the inboard vertical rod (10) of scaffold on the middle jaw position of two clamps (8).Two clamps (8) can be around bearing pin (9) swing, to form jaw to the clamping of vertical rod (10) or unclamp.Two pull bars (6) are connected the both sides of two clamps (8) by hinge pin (7), on two pull bars (6) omoplate are arranged, and back-up ring (5) is arranged at the omoplate place, and compression spring (4) and spring base (3) are arranged below back-up ring (5).Connect a cross bar (2) in the lower end of two pull bars (6) by bolt, be connected with connecting rod (1) in the central authorities of cross bar (2), the suspension hook of connecting rod (1) and jacking equipment is connected.When operate as normal, under the gravity of jacking equipment, two pull bars (6) are pulled down by cross bar (2), its pulling force and compression spring balance each other, and the jaw of two clamps (8) unclamps; Steel cable disconnects or cucurbit is broken off relations when taking place, and tightly embraces the inboard vertical rod (10) of scaffold because of losing jaw that weight makes two clamps (8), prevents to fall.
Claims (2)
1. the safety dropping prevent mechanism of boat scaffold, it is characterized in that: two clamps are connected on the body of this mechanism with eccentric bearing pin symmetrically, it on the middle jaw position of two clamps the inboard vertical rod of scaffold, two pull bars are connected the both sides of two clamps by hinge pin, on two pull bars, omoplate is arranged, there is back-up ring at the place at omoplate, compression spring and spring base are arranged below back-up ring, lower end at two pull bars connects a cross bar by bolt, there is connecting rod in central authorities at cross bar, and the suspension hook of connecting rod and jacking equipment is connected.
2. the safety dropping prevent mechanism of boat scaffold according to claim 1, it is characterized in that: there is the extension arm of frame construction in this mechanism, is suspended on the outside of semi girder.
