Description
Technical field
The utility model relates to building machinery, but relates in particular to the retaining mechanism that a kind of anti-hoisting scaffold is fallen
Background technology
Along with building constantly increases, but hoisting scaffold is improved synchronously by lifting means.Hoisting scaffold is in the process that promotes, if the stressed member that lifting means damages or promotes damages, the stressed mistake of hoisting scaffold is carried and will be produced the phenomenon of falling, in case when therefore taking place when falling, one retaining mechanism must be arranged, a kind of fall arrest retaining mechanism of lifting means that will fall and the locking of pin hand.
But the mechanical type anti-fall device of the present hoisting scaffold of using always as shown in Figure 3, and it mainly is made up of cylindrical shell 117,118 pressing plates, spring 121, load axle 120 and office's pin 119.When scaffold was desired to fall owing to certain accident, the stressed mistake of scaffold was carried, and drive office pin 119 is transferred to, and load axle 120 ejects under the effect of spring force, play anti-fall effect in the strut rail space of the vertical framework of load axle 120 meeting insertion integral-scaffolds.The load axle meeting flexural deformation of this anti-drop device, anti-fall weak effect, the strut rail space processing trouble of the vertical framework of scaffold.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, but designs a kind of anti-fall reliable for effectly and be convenient on scaffold to install the retaining mechanism that a kind of anti-hoisting scaffold implemented is fallen, and it is implemented by following technical scheme:
Comprise the pressing plate return spring, guide pillar, thimble, steel ball, steel ball return spring and cross-under pressing plate and the lock body on described anti-fall pull bar, pressing plate places the upside of lock body, several guide pillars are connected on the pressing plate end face facing to lock body one side, the pressing plate return spring is plugged on the guide pillar, its free end is pressed and is touched on lock body, be evenly equipped with several inclined holes and several pilot holes on the lock body, each inclined hole upside is provided with the centre hole that is communicated with it, steel ball and steel ball return spring place in the inclined hole, thimble is plugged in the centre hole and by touching on steel ball from weight, guide pillar is plugged in the pilot hole, described lever one end is connected the pressing plate upper end, one end is connected with the free end of pressing plate return spring, at lever pressing plate is produced described pushing and pressing and do the time spent, pressing plate by thimble pushing and pressing steel ball along inclined hole to moving away from anti-fall pull bar axis direction, and compression steel ball return spring, at lever pressing plate is not had described pushing and pressing and do the time spent, the pressing plate return spring makes the pressing plate return, and steel ball return spring pushing and pressing steel ball moves to close anti-fall pull bar axis direction along inclined hole.
Described lock body is made up of cylinder, post circle and gland, and gland is connected the upper end of cylinder by screw, and post circle close-fitting is at the outer circumferential side of cylinder, and described several inclined holes and several pilot holes are separately positioned on cylinder and the post circle, and several centre holes are arranged on the gland.
The outer circumferential side of described gland is connected with dust cover.
The utility model connects the retaining mechanism and the lifting means that can be locked on the anti-fall pull bar by a lever, and this lifting means connects scaffold.When the scaffold that can promote falls, lever is rotated, the steel ball on the retaining mechanism will be pressed on the anti-fall pull bar, and whole retaining mechanism is locked on the anti-fall pull bar.Like this, scaffold and lifting means also are locked on the anti-fall pull bar.And retaining mechanism can only move up, and can not move down, so this locking is very reliable.Retaining mechanism is simple in structure simultaneously, needs only its cross-under on anti-fall pull bar, installs very convenient.
Description of drawings
Fig. 1 is the structural representation that the utility model is in locking state.
Fig. 2 is the structural representation that the utility model is in releasing orientation.
But Fig. 3 is the mechanical type anti-fall device structural representation of existing hoisting scaffold.
Among the figure, 2 anti-fall pull bars, 3 levers, 20 retaining mechanisms, 21 pressing plates, 22 dust covers, 23 pressing plate return springs, 24 guide pillars, 25 post circles, 26 inclined holes, 27 steel ball return springs, 28 steel balls, 29 glands, 30 thimbles, 31 cylinders, 32 dust covers, 33 pilot holes.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Contrast Fig. 1, retaining mechanism 20 of the present utility model mainly is made up of pressing plate 21, return spring 23, guide pillar 24, thimble 30, steel ball 28, steel ball return spring 27, pressing plate 21 and lock body.Lock body then is made up of cylinder 31, post circle 25 and gland 29, and gland 29 is connected the upper end of cylinder 31 by screw, and post circle 25 close-fittings are in the outer circumferential sides of cylinder 31.Be evenly equipped with three centre holes on the gland 29, the position of cylinder 31 corresponding three centre holes is provided with three inclined holes 26, and each centre hole is communicated with corresponding inclined hole 26.Return spring 23 places the bottom of inclined hole 26, and steel ball 28 is placed on the upper end of return spring 23, and thimble 30 is plugged in the centre hole, and its lower end is by touching on steel ball from weight.
Lifting means and scaffold act on retaining mechanism of the present utility model by lever 3, and an end of lever 3 is connected (see figure 3) by the upper end of the pressing plate 21 in bolt 13 and the retaining mechanism, and the other end is connected with lifting means and scaffold.
Be at lifting means and upwards climb or when climbing state downwards, to produce active force to the link of lever 3, link to retaining mechanism produces downward active force thus, make pressing plate 21 to pressing down, thimble 30 downward pressing steel balls 28, steel ball 28, be not pressed on the anti-fall pull bar 2 to moving away from anti-fall pull bar axis direction along inclined hole 26, steel ball return spring 27 is compressed, and retaining mechanism is in releasing orientation.At this moment, lifting means drive scaffold climbs or climbs, and retaining mechanism is inoperative to lifting means and scaffold.
When lifting means loses when supporting suddenly, the link of lever 3 is not produced active force, then the pressing plate 21 no downward pressures on 3 pairs of retaining mechanism 20 tops of lever.Pressing plate 21 will move up under the effect of return spring power 5, and this moment, thimble no longer was subjected to the compacting of pressing plate 21, and steel ball moves to close anti-fall pull bar axis direction along inclined hole under the effect of steel ball return spring, makes steel ball be locked on the anti-fall pull bar.And anti-fall pull bar is fixed, so whole anti-drop device can only move up, can not move down, and plays the fall arrest effect in the scaffold lifting process, i.e. locking state.Like this, retaining mechanism 20 just can effectively prevent lifting means and the falling of the scaffold that is attached thereto, and connection system for guide rail firmly is locked on the anti-faller.
