Abstract
The anti-falling device of the attached scaffold is provided with a clamp locking mechanism which consists of a clamp, a pull rod, compression springs and spring seats, wherein the two sides are symmetrically distributed, the clamp is connected through a hinge pin, the inner side vertical rod of the lifting scaffold is arranged between the jaw of the clamp, the other end of the clamp is respectively provided with the pull rod which is connected with the hinge pin, the pull rod is respectively fixed with a retaining ring, the compression springs and the spring seats are respectively arranged below the retaining rings, the lower ends of the two pull rods are connected with a link rod, and the middle part of the link rod is connected with a hook lifting rod. The utility model has the advantages that when the steel rope connected with the scaffold and the lifting device is broken or the hoist is unhooked, the falling accident of the scaffold can not be caused.
Description
The utility model relates to the anti-drop device that adheres to scaffold that building operations is used.
The crossbeam that adheres to scaffold and be by fluctuating orbit is connected on the building, along with the increase of depth of building, adheres to scaffold and also constantly raises.Adhere to scaffold in the process that promotes or descend, because the steel rope breaking that scaffold is connected with jacking equipment, perhaps cucurbit is broken off relations, and all can cause the falling accident of scaffold.
The purpose of this utility model is to overcome above-mentioned weak point and the anti-drop device that adheres to scaffold is provided, and when running into the steel rope breaking that scaffold is connected with jacking equipment, perhaps cucurbit is broken off relations, and can not cause the falling accident of scaffold.
Description of the present utility model is as follows: one of crossbeam is connected with building floor plates face in the work progress, and the other end of crossbeam is connected with fluctuating orbit.The anti-drop device that adheres to scaffold is suspended on the inboard of the crossbeam outside, fluctuating orbit with cross-arm.What be connected with cross-arm is the extension arm of frame construction, hangs the body that is connected with anti-drop device below the arm.The clamp retaining mechanism is housed on body, and the clamp retaining mechanism is made up of clamp, pull bar, compression spring and spring base.Clamp, pull bar, compression spring symmetrical distribution both sides.Clamp connects by hinge pin, can swing, and forms jaw between the head of two clamps, and the inboard vertical rod of lifting false work just places between the jaw of clamp.The other end at two clamps respectively has a pull bar to be connected with its hinge pin.Each fixes a back-up ring on the pull bar, and a compression spring is respectively arranged below back-up ring, and the compression spring places in the spring base.Lower end at two pull bars connects a link rod, and the middle part of link rod is connected with the suspension hook bar, and suspension hook is equipped with in the bottom of suspension hook bar.Jacking equipment hangs on the suspension hook.When operate as normal, because the weight of jacking equipment, by link rod two pull bars are pulled down, the weighing apparatus that maintains an equal level of trying hard to keep of its pulling force and compression spring, because pull bar pulls down, two clamps rotate an angle around hinge pin, thereby jaw is opened, and the inboard vertical rod of lifting false work moves up and down between open jaw.Break off relations in case rope fracture or cucurbit are taken place, two pull bars lose gravity upwards operation under the compression spring action, drive two clamps around angle of hinge pin counter-rotation, thereby make jaw clamp the inboard vertical rod of lifting false work.Because the utility model device is suspended on the crossbeam of building, make the scaffold of oscilaltion and equipment aloft with regard to clamping stagnation, prevent to fall and accidents caused.
Description of drawings:
Fig. 1 is the installation site figure that adheres to the anti-drop device of scaffold of the present utility model.1-floor plates face among the figure, the 2-crossbeam, 3-hangs arm, 4-fluctuating orbit, the inboard column of 5-lifting false work.
Fig. 2 is the structural representation that adheres to the anti-drop device of scaffold of the present utility model.2-crossbeam among the figure, 3-hangs arm, the inboard column of 5-lifting false work, the 6-cross-arm, the 7-hinge pin, the 8-clamp, the 9-pull bar, the 10-back-up ring, 11-compresses spring, 12-spring base, 13-link rod, 14-suspension hook bar.
Embodiment makes like this: one of crossbeam (2) is connected with building floor plates face (1) in the work progress, and the other end of crossbeam (2) is connected with fluctuating orbit (4), and crossbeam (2) adopts i iron.The anti-drop device that adheres to scaffold of the present utility model is suspended on the outside of crossbeam (2), the inboard of fluctuating orbit (4) with cross-arm (6).What be connected with cross-arm (6) is frame construction and hangs arm (3), hangs the body that is connected with anti-drop device below the arm (3).The clamp retaining mechanism is housed on body.The clamp retaining mechanism is made up of clamp (8), pull bar (9), compression spring (11) and spring base (12).Clamp (8) connects by hinge pin (7), can swing, and forms jaw between the head of two clamps (8), and the jaw expansible can be clamped.The inboard vertical rod (5) of lifting false work just places between the jaw of clamp (8).The other end at two clamps (8) respectively has a pull bar (9) to be connected with its hinge pin.Go up each at pull bar (9) and fix a back-up ring (10).A compression spring (11) is respectively arranged below back-up ring (10), and compression spring (11) places in the spring base (12).Lower end at two pull bars (9) connects a link rod (13), and the middle part of link rod (13) is connected with suspension hook bar (14), and suspension hook is equipped with in the bottom of suspension hook bar, and jacking equipment just hangs on the suspension hook.When operate as normal, because the weight of jacking equipment, the elastic force that makes two pull bars (9) overcome compression spring (11) by link rod (13) pulls down, make two clamps (8) rotate an angle around hinge pin (7), thereby jaw is opened, the inboard vertical rod (5) of lifting false work moves up and down between open jaw, finishes lifting action.In case rope fracture or cucurbit are taken place breaks off relations, two pull bars (9) lose gravity upwards operation under compression spring (11) effect, drive two clamps around angle of hinge pin (7) counter-rotation, thereby make jaw clamp the inboard column (5) of lifting false work, prevent to fall and accidents caused.
Advantage of the present utility model: use the anti-fall device of attached scaffold, when running into scaffold and jacking equipment The steel rope breaking that connects, perhaps cucurbit is broken off relations, and can not cause the falling accident of scaffold.
