Abstract

A building fitting lifting basket safety box is used in the building fitting lifting basket. The safety box is composed of an inside box and an outside box. The inside box is provided with a groove, and the outside box is provided with a projection and two blocks. The safety box and a lifting basket are fixed by a guide bracket. A hoist rope of the lifting basket and a safety rope are all passed by the safety box. Once the hoist rope occurs the break, the safety box can clamp the lifting basket to the safety rope to prevent the lifting basket from falling and protect the personal safety.

Description

Building fitting lifting basket safety box

The utility model relates to a kind of safety stop of elevation and subsidence mechanical, is a kind of building finishing hanging basket safety box specifically.

The finishing hanging basket is used for the work such as decoration, repairing and cleaning of building outside.For prevent hanging basket when work because of hoist rope disrumpent feelings dropping suddenly therefore the so that accident that causes casualties will install safety stop thereon.The safety stop of using on the at present domestic and international elevation and subsidence mechanical is centrifugal, for example design by room, corridor building machinery research institute, the centrifugal force stop hanging basket safety rope that the building finishing hanging basket safety stop that Wuxi Engineering Machinery Plant produces utilizes flyball to produce, flyball is then by the series of gears transmission mechanism control.Therefore this centrifugal hanging basket safety has: the stop distance is longer, complex structure, and weight is big, shortcomings such as cost height.

The purpose of this utility model is to provide building finishing hanging basket safety box a kind of simple in structure, in light weight, safe.

The purpose of this utility model can reach by following measure:

Safety box is made up of inside and outside two cans, outer box is fixed on the hanging basket frame, there is one can contact with the safety wire rope and on the inwall of outer box along the groove of safety rope longitudinal extension, inner box rotates around dead axle in the box outside, the end that inner box is relative with safe wire rope is fixed a special-shaped projection that work plane is coarse, two pulleys up and down are housed on the right side of projection, the axle of top sheave is bearing on the wall of outer box and as the pivot of inner box rotation, hoist rope from the right side of top sheave along the interior tangent line altogether of pulley up and down, the left side of walking around lower sheave links to each other with the reel of hoist engine, safe steel wire penetrating groove links to each other with weight with gap between special-shaped projection, inner box and outside be equipped with one between the box and adjust screw and a spring.On special-shaped projection and work plane that safe wire rope contacts, have groove and rib tooth.

Fig. 1 is the installation site schematic diagram of finishing hanging basket safety box.

Fig. 2 is the structural representation of finishing hanging basket safety box.

Below in conjunction with drawings and Examples the utility model is further described:

As shown in Figure 1, 2, finishing hanging basket 6 is hung on the outrigger 2 on roof 1 by hoist rope 3, and the reel 7 of hoist engine can be with hoist rope 3 around going into or emit, and whole hanging basket is hoisted or descends.For preventing to drop, a safety box 5 is installed on the saddle 8 of hanging basket because of the hoist rope 3 unexpected disrumpent feelings hanging baskets that cause.The upper end is cemented in the safe wire rope 4 on the outrigger 2, be passed down through on outer box 9 inwalls of safety box groove 15 be fixed on inner box 10 on special-shaped projection 14 between the gap link to each other with weight 17, owing to the safe wire rope 4 of effect of weight 17 vertically is suspended from above the ground.Hoist rope 3 is through outer box 9, and inner box 10 is supported on the pulley 11 on the inner and outer box, and the pulley 12 that is supported on the inner box is guided on the reel 7 of hoist engine.Two pulleys 11,12 had both play the guiding role up and down, played projection relieving effect voluntarily again.When hoist rope 3 is mentioned hanging basket 6, because the downward tension force of hoist rope makes pulley 12 rotate counterclockwise with the pivot of inner box 10 around pulley 11, so make the special-shaped projection 14 that is fixed on the inner box away from safety wire rope 4, it is adjusted by adjusting screw 16 away from the size in gap, thus hoist or decline work in the hanging basket lifting freely.Just in case when hoist rope is disrumpent feelings, the tension force of hoist rope itself disappears, spring 13 then makes inner box 10 clockwise rotate around the pivot of pulley 11 rapidly, projection 14 is pressed on safe wire rope in the groove 15 on the outer box inwall immediately, owing to have groove and rib tooth on the projection work plane, the frictionally self-locking is become one with safety box and safe wire rope, and safety box is fixed on the hanging basket saddle, drops so prevented hanging basket.

Compare with known centrifugal hanging basket safety, the utility model has following advantage:

(1) safe. The generation hoist rope is disrumpent feelings, and the hanging basket distance of glide is less than 100mm.

(2) simple in structure, in light weight. The utility model---construction and decoration lifting basket safety box only has more than ten common parts altogether, and structure is very simple, and its gross weight is no more than 3 kilograms.

(3) cost is low.Since simple in structure, in light weight, make and produce cost of the present utility model, and cost descends significantly.A common centrifugal hanging basket safety is wanted thousands of units, and this building finishing hanging basket safety box only needs dozens of yuan.

Claims

1, a kind of building finishing hanging basket safety box, it is characterized in that this box is made up of inside and outside two cans, outer box 9 is fixed on the hanging basket frame 8, there is one can contact with safety wire rope 4 and on the inwall of outer box along the groove 15 of safety rope longitudinal extension, inner box 10 rotates around dead axle in the box 9 outside, the end that inner box is relative with safe wire rope is fixed a special-shaped projection 14 that work plane is coarse, two pulleys up and down are equipped with on its right side, the axle of top sheave 11 is bearing on the wall of outer box 9 and as the pivot of inner box 10 rotations, hoist rope 3 from the right side of top sheave 11 along the interior tangent line altogether of pulley up and down, the left side of walking around lower sheave 12 links to each other with the reel 7 of hoist engine, the gap that safe wire rope 4 passes groove 15 and 14 of special-shaped projections links to each other with weight 17, inner box and outside be equipped with one between the box and adjust screw 16 and a spring 13.

2, by the described building finishing hanging basket of claim 1 safety box, it is characterized in that having groove and rib tooth on special-shaped projection 14 work planes.
