Abstract
The utility model discloses an automatic escalator with chain breakage detection device, this automatic escalator can in time control the host computer when the step chain breaks off and shut down, avoids personnel's injury and automatic escalator spare part to damage. The utility model discloses a step chain track arranges the step chain in step chain track, still arranges detection sensor in step chain track in addition, detection sensor is in the below of step chain.
Description
Technical field
The utility model belongs to the escalator technical field, relates in particular to a kind of escalator with broken chain detecting device.
Background technology
During existing escalator normal operation, step chains is moved in the step chains track as drive disk assembly.Yet in case the open circuited situation of step chains takes place, main frame is work as usual still, so not only can cause personnel to injure, and can cause the damage of the related components such as step of escalator.
The utility model content
Technical problem to be solved in the utility model provides a kind of escalator with broken chain detecting device, and this escalator can be shut down by timely main control system when step chains disconnects, and avoids personnel to injure and the escalator damage of components.
The utility model comprises the step chains track, arranges step chains in the step chains track, also arranges detecting sensor in addition in the step chains track, and described detecting sensor is in the below of step chains.
During escalator generation chain rupture accident in the utility model, because the effect of gravity, step chains can move downward voluntarily, cause the spacing of step chains and detecting sensor to be dwindled, until step chains touching detecting sensor, produce electric signal, trigger master controller and make Main Engine Cut-Off.
Preferably, described detecting sensor is connected in the step chains track by a plate.
Preferably, described detecting sensor is in the segmental arc place of step chains rail end.
Detecting sensor is in the segmental arc place of step chains rail end, so not only can not hinder the proper motion of step chains, and step chains when disconnecting because the effect of gravity, it can be assembled to the segmental arc place of step chains rail end, thereby can guarantee the reliability of open circuited step chains touching detecting sensor.
Figure of description
Fig. 1 is the structural representation with escalator of broken chain detecting device.
The specific embodiment
As shown in Figure 1, arrange step chains 2 in the present embodiment in the step chains track 1 of escalator, arrange detecting sensor 3 in described step chains track 1, described detecting sensor 3 is in the below of step chains 2.Preferably, described detecting sensor 3 is connected in the step chains track 1 by a plate 4.
When chain rupture accident took place, because the effect of gravity, step chains 2 can move downward voluntarily, caused the step chains 2 and the spacing of detecting sensor 3 to be dwindled, and until step chains 2 touching detecting sensors 3, produced electric signal, triggered master controller and made Main Engine Cut-Off.
In addition, detecting sensor 3 preferably is in the segmental arc place of step chains track 1 end, so not only can not hinder the proper motion of step chains 2, and step chains 2 when disconnecting because the effect of gravity, it can be assembled to the segmental arc place of step chains track 1 end, thereby can guarantee the reliability of step chains 2 touching detecting sensors 3.
Claims (3)
1, the escalator that has broken chain detecting device comprises the step chains track, arranges step chains in the step chains track, it is characterized in that: also arrange detecting sensor in the step chains track, described detecting sensor is in the below of step chains.
2, the escalator with broken chain detecting device according to claim 1, it is characterized in that: described detecting sensor is connected in the step chains track by a plate.
3, the escalator with broken chain detecting device according to claim 1 and 2 is characterized in that: described detecting sensor is in the segmental arc place of step chains rail end.
