Abstract

The utility model discloses a safety anti-falling device for construction hanging basket, which can make the hanging basket hang on the construction frame timely when the hanging basket is fallen accidentally, and the utility model is fixed on the construction hanging basket. The device comprises a hanging rod, one end of the hanging rod is provided with a hook, and the other end of the hanging rod is fixedly connected to a hanging seat; the hanging seat has a rotating connection with the hanging basket along a pin shaft, both ends of a spring are respectively connected to the hanging seat and the spring, and a steel rope is directly connected with the hanging rod and the steel cable of the hanging basket. The utility model solves the problem that the hanging rods in the existing anti-falling devices has not reliable anti-falling effect, and even cause the problem of the collapse of the construction frame because the sliding is not nimble and the outer extending section is straight line which is not easy to hang on the construction frame. The utility model has the advantages of simple structure, low cost, and good effect.

Description

The safe anti-drop device of building hanging basket

The utility model is a kind ofly to be fixed on the usefulness on the building hanging basket so that hanging basket can be suspended on the safe anti-drop device of building on the derrick in time when accident is fallen.

Existing building hanging basket anti-drop device can see that the former is its elevation from Fig. 1 and Fig. 2.The latter is its vertical view.Represent building hanging basket 7 with double dot dash line among the figure.On four angles of hanging basket an anti-drop device is housed respectively.Each anti-drop device includes the block set 2 and the pulley 5 that are fixed on the band through hole on the building hanging basket 7, but the peg 1 of a move left and right is housed in the through hole of block set, on the extension bar affixed one walk around pulley and be tightened on the cable wire 6 of hanging basket so that peg is retracted within the wire rope 4 in the cover block hole, an energy also has been installed when cable wire 6 is torn in the through hole simultaneously, that is during wire rope 4 ' lax, an end of peg can in time stretch out the outer spring 3 of cover block hole '.Dotted line among Fig. 1 and Fig. 2 is expressed the overhanging position of peg.Overhanging peg can rest on the crosspiece of derrick hanging basket in time when falling.Thereby prevent that hanging basket from further falling.The shortcoming of this anti-drop device is: 1) because of peg is bigger with the slip resistance between the block set, it is dumb to move, even inactive because of the jail of becoming rusty between the two.Therefore this device is difficult for outstanding resting on the derrick, and its anti-fall effect is unreliable, even loses efficacy; 2) overhanging section of peg is linear, it can only be shelved on crosspiece and can not hang, so essential uniform two or more anti-drop devices simultaneously on each hanging basket, and hanging basket the peg in each device all should be simultaneously overhanging when falling, otherwise hanging basket tilts, peg slippage from the derrick crosspiece, and hanging basket still falls; 3) hanging basket that tilts to fall can clash into derrick, thereby causes the accident that derrick collapses.

The purpose of this utility model is the shortcoming that overcomes above-mentioned existing hanging basket anti-drop device, provide a kind of simple in structure, cost is low, can prevent the safe anti-drop device of the building hanging basket that hanging basket falls timely and effectively.

The safe anti-drop device of building hanging basket includes: be connected hanging seat, peg, wire rope and spring on the hanging basket, characteristics of the present utility model are: a 1) end band crotch shape of peg, and end is fixed on the hanging seat in addition; 2) have the axis hole that it is rotatably connected with the bearing pin composition with hanging basket on the hanging seat; 3) wire rope has directly connected the cable wire of peg and hanging basket; 4) two ends of spring are connected on hanging seat and the hanging basket, and the spring after installing can be swung outside hanging basket around bearing pin should be satisfied with the peg spring-loaded time.

To and contrast accompanying drawing by embodiment below, the utility model anti-drop device will be done further narration.Have in the accompanying drawing:

Fig. 1 and Fig. 2 are respectively the elevation and the vertical views of existing building hanging basket anti-drop device;

Fig. 3 is the safe anti-drop device structural perspective in use of the utility model building hanging basket;

Fig. 4 is the elevation among Fig. 3;

Fig. 5 is the A-A sectional view among Fig. 4;

Fig. 6 is the structure elevation of the spring in the utility model anti-drop device when installing on diverse location.

See from Fig. 3, the safe anti-drop device of four the utility model building hanging baskets is housed on the hanging basket 9 that has a cable wire 8, each device is fixed on the channel beam 5 of hanging basket, (cable wire 8 among the figure, hanging basket 9 and channel beam 5 are all represented with double dot dash line), their downward projection is all in the downward projection of hanging basket.Thereby do not influence the normal operation of hanging basket in the building derrick.

The structure of the safe anti-drop device of each building hanging basket also can further be seen from Fig. 4 and Fig. 5.It includes peg 1, hanging seat 2, spring 3 and wire rope 4.One end band crotch shape of peg, end is welded on the hanging seat in addition, with the affixed one of hanging seat.Hanging seat comprises the steel disc in two tape spool holes, and the two ends of bearing pin 7 are fixed in the axis hole.And this bearing pin simultaneously kink one with hanging basket on the through hole of the block set 6 that is welded into one of channel beam 3 in.One end of wire rope 4 is fixed on the peg, and end is tightened and is fixed on the cable wire in addition.Spring 3 can be extension spring, also can be stage clip, and its end is fixed on the channel beam 5 of hanging basket, and end is fixed on the hanging seat in addition.Do the time spent at spring force, the crotch end of peg should rotate outside the sidewall of hanging basket and stop on this position.Spring also can the position B from Fig. 4 be changed to position C or the D among Fig. 6.The quantity of spring can be more than 1 or 1.

In use, earlier wire rope is tightened, at this moment cable wire 8 remains on the position of vertical line, and the downward projection of the safe anti-drop device of building hanging basket is in the downward projection of building hanging basket.If meet accident, as cable wire 8 be torn or hanging basket soaring, then wire rope 4 is promptly loose, rotate in peg outside to hanging basket under spring 3 effect.The overhanging peg of rotation can be hanging on the crosspiece of building derrick the hanging basket that falls in time.Thereby the accident of avoiding hanging basket to fall.

The advantage of the safety anti-falling device of the utility model building hanging basket is: 1) hanging seat is at bullet Neatly rotation under the effect of spring power. Therefore, in the moment that cable wire is pulled apart, peg can reach The time to be extended to the hanging basket downward projection outer and be suspended to by the crotch on it on crosspiece of derrick, it Anti-fall effective. Really play the effect of safe anti-falling: 2) simple in structure, cost is low, And exposing of spring both is convenient to safety inspection. Also be convenient to the maintenance to it, thereby guaranteed anti-The reliability of fall device, and long service life.
