Abstract

The utility model relates to a safety anti-falling device for a simple elevator, comprising an electric lock and a stop welded on the guide rail and the hanging scaffold of the elevator, wherein, the electric lock is formed by an electric magnet, a lock tongue, a tension spring, a connecting plate, a casing, a clamping plate, etc. The stop is an iron plate, an iron frame, or the hanging scaffold self which is arranged on the hanging scaffold or the track and can block the lock tongue. The utility model can be arranged on the elevator and can be used for preventing the hanging scaffold falling and ensuring job safety, having the advantages of simple structure, low cost, easy installation, simple operation, and safety.

Description

Safety device for preventing wrong fall of lifter

The utility model relates to a kind of safe anti-fall device that is used for the simplified elevator aspect.

Used elevator of unit such as factories and miness, building operation such as well cabinet frame, portal frame, delta queue door frame etc., for preventing that hanging scaffold from contingencies such as disconnected rope or brake failure taking place, often take falling protector to be installed or to be used iron rod, steel rope tangles methods such as hanging scaffold, but existing falling protector is complex structure mostly, the cost height has inconvenience in the use; Tangle this way poor reliability of hanging scaffold with iron rod or steel rope, can not guarantee safety.

It is a kind of simple in structure that the purpose of this utility model is to provide, and fitting operation is easy, and is cheap, safe and reliable elevator safety anti-fall device.

Technical solution of the present utility model is: form elevator safety anti-fall device by the electric lock and the buting iron that are welded on respectively on elevator guide rails and the hanging scaffold.Wherein, electric lock is to be made of electromagnet, dead bolt, connecting panel, extension spring, case panel, clamping plate etc., one end of connecting panel 5 is connected with the bottom of extension spring 2, the other end is connected with electromagnet 8, the top of extension spring 2 is fixed on the lock body top, the inner end that is embedded in the dead bolt 13 in the both sides clamping plate 11 is connected with the middle part of connecting panel 5, and the tip of the tongue end of dead bolt 13 is stretched out outside the housing 1 by the opening part of case panel 12, and case panel 12 and buting iron 15 are welded on respectively on elevator guide rails 10 and the hanging scaffold 16.

When the utility model uses, by electric switch control dead bolt 13, when hanging scaffold 16 when track 10 rises, buting iron 15 moves along the inclined-plane of dead bolt 13, and dead bolt 13 is kick-backed in the lock body automatically.When hearing the sound that card reaches, dead bolt 13 heavily stretches out outside the lock body again under the pulling force of extension spring 2, blocks buting iron 15, just reaches the purpose that prevents that hanging scaffold from descending.When hanging scaffold descends, must be in electrical power, the electromagnet adhesive of also switching on simultaneously, dead bolt 13 is retracted in the lock body, do not have the lock tongue obstacle in the track, hanging scaffold is able to smooth decline, and its principle is the same with the door built-in lock, want to open the door and must use key, only the key of electric lock is the control of current consumer switch.

Advantage of the present utility model is that structure and principle are simple, easy to install and use, cheap, dependable performance, and the safety guard-safeguard effect is obvious, and is applied widely.

Following accompanying drawing has been described an embodiment of the present utility model.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model scheme of installation.

Below in conjunction with accompanying drawing the utility model is described in detail.

In the present embodiment, form elevator safety anti-fall device by electric lock 17 and buting iron 15, wherein, electric lock 17 is by electromagnet 8, and dead bolt 13, connecting panel 5, extension spring 2, case panel 12, clamping plate 11 etc. constitute.One end of connecting panel 5 is connected with the bottom of extension spring 2 by bearing pin 3, the other end is connected with electromagnet 8 by bearing pin 7, electromagnet 8 is towed electromagnet, the top of extension spring 2 is fixed on the lock body top, the inner end that is embedded in the dead bolt 13 in the both sides clamping plate 11 is connected with the middle part of connecting panel 5 by bearing pin 6, the tip of the tongue end of dead bolt 13 is stretched out outside the housing 1 by the opening 14 of case panel 12, dead bolt 13 is connected with both sides clamping plate 11 by bearing pin 4, case panel 12 and buting iron 15 are welded on respectively on elevator guide rails 10 and the hanging scaffold 16, in the present embodiment, electric lock 17 is welded on the elevator guide rails 10 by case panel 12, buting iron 15 is welded on the elevator hanging scaffold 16, and want mounted in pairing mode, this installation form of the present utility model is applicable to that two layers are used elevator; Three layers of elevator time spent, two pairs of elevator safety anti-fall devices can be installed, when the elevator more than four layers is installed the utility model, electric lock 17 can be welded on the elevator hanging scaffold 16, buting iron 15 is welded on the elevator guide rails 10, at this moment, the elevator cable moves with hanging scaffold, buting iron 15 can be iron plate, iron hoop, brandreth etc., when if dead bolt 13 can block hanging scaffold 1, can directly adopt hanging scaffold itself to do buting iron, as long as can block the dead bolt of electric lock, hanging scaffold can not be descended get final product, 9 is the electromagnet power supply switch among the figure.

When the utility model uses, notice that under normal circumstances buting iron can not sit on above the electric lock dead bolt, should maintain the distance more than two centimeters between the two, be convenient to the dead bolt retraction.When if buting iron sits on the dead bolt, must start the rising button, descend again after making buting iron leave dead bolt.

When the utility model is installed, can be in hanging scaffold flat bed place, in down and each position, top install, be the best but preferably match to use with the flat bed limit switch.

The effect of the utility model safety guard-safeguard is obvious, and behind the hanging scaffold flat bed, electric lock can produce the sound that card reaches, and the operator can see that hanging scaffold has been blocked by electric lock and relieved on hanging scaffold handling goods.

The utility model applicability is extensive, can be on the two sides or the four sides for installing on the elevator of guide rail.No matter elevator guide rails is channel-section steel, or angle steel, I-beam section, garden steel, steel pipe etc. all can be installed and play the safety guard-safeguard effect.
