Abstract

The utility model relates to a device used for protecting a vertical lift parking system against falling down. The device used for protecting a vertical lift parking system against falling down of the utility model comprises an upright and a lift platform, on which a sheave base is arranged, and a sheave is arranged on the sheave base; a sling passes through he lift platform and then hangs the sheave, the longitudinal width of a sheave installing hole on the sheave base is greater than the longitudinal width of the sheave shaft so that the sheave can move up and down in the sheave installing hole; pop-up devices are arranged on four peaks of the lift platform, and extension pillars of the pop-up devices are connected with a stay rope one end of witch is connected with the sheave shaft; the upright is provided with teeth coordinated with the pop-up devices. The utility model has a simple structure and high safety factor.

Description

The falling proof device of vertical lift type parking equipment

Technical field

The utility model relates to a kind of falling proof device of vertical lift type parking equipment.

Technical background

Vertical lift type parking equipment is by hoist cable lift platform to be risen to the height at place, garage, by moving guide rail it is moved in the garage again.In this equipment, the falling proof device of lift platform has this crucial effects to the safe operation of support equipment.The complex structure that existing falling proof device has, manufacturing cost height, the unreasonable structure, the safety factor that have are low.

Summary of the invention

The purpose of this utility model provide a kind of rational in infrastructure, safety factor is high, the falling proof device of the vertical lift type parking equipment of low cost of manufacture.

For achieving the above object, the utility model adopts following technical scheme:

The falling proof device of vertical lift type parking equipment described in the utility model comprises column and lift platform, lift platform is provided with pulley base, pulley is installed on the pulley base, hoist cable passes pulley lift platform is hung, vertical width of the pulley installing hole on the pulley base can move up and down pulley greater than vertical width of pulley axle in the pulley installing hole; Four jiaos of lift platform are provided with ejector, connect drag-line on the telescopic mast of ejector, and the other end of drag-line is connected with the wheel shaft of pulley, have the tooth of choking that cooperates with ejector on the column.

When normal the use, pulley is hung by hoist cable, is connected drag-line with pulley the telescopic mast of ejector is held, and the telescopic mast withdrawal does not hinder the motion of lift platform.Once hoist cable fracture or break away from pulley, the telescopic mast ejecting card of ejector is on the tooth of choking of column, and avoiding continues to glide causes the loss of personnel and property.The utility model is simple in structure, safety factor is high.

The specific embodiment

As shown in Figure 1, the falling proof device of vertical lift type parking equipment described in the utility model comprises lift platform 2 and the column 1 that is arranged on 2 four jiaos of lift platforms.Lift platform 2 is provided with pulley base 3, pulley 4 is installed on the pulley base 3, hoist cable 5 passes pulley 4 lift platform 2 is hung, and vertical width of the pulley installing hole on the pulley base 3 can move up and down pulley 4 greater than vertical width of pulley 4 wheel shafts in the pulley installing hole; Four jiaos of ejectors that are provided with as shown in Figure 6 of lift platform 2, this ejector comprises that being fixed on the lift platform 2 is guide pipe 9, is installed in telescopic mast 7 and spring in the guide pipe 9, spring makes telescopic mast 7 have the trend of outside ejection, the other end of drag-line 6 is fixed on the junction plate 10 after walking around two angle pulleys, junction plate 10 is pressed on the wheel shaft of pulley 4, has the tooth 8 of choking that cooperates with ejector on the column 1.As Fig. 2, shown in Figure 4, when normally using, hoist cable 5 hangs pulley 4, because the cause of deadweight, lift platform 2 has the trend of tenesmus, and the wheel shaft of pulley is positioned at the top of pulley installing hole, and wheel shaft is held drag-line, prevents that telescopic mast 7 from ejecting.

When sling falling, pulley loses pulling force, drops to the bottom of pulley installing hole under the effect of drag-line, and drag-line loses pulling force, and as Fig. 3, shown in Figure 5, telescopic mast ejects under spring action, is stuck on the tooth of choking of column, stops lift platform to continue to glide.

Certainly, the method of attachment of drag-line and pulley spindle can have multiple, can be pressed on the pulley spindle by junction plate as the utility model, also can will two drag-lines be pressed on the pulley spindle after connecting, can also directly be fixed on drag-line on the pulley spindle or allow drag-line pass through hole on the pulley spindle; Ejector also can have a variety of forms, can adopt extension spring also can adopt spring as the spring in the ejector.
