Description

Escalator cover plate with loosening alarm function

Technical Field

The utility model relates to an automatic staircase device, in particular to possess not hard up alarming function's staircase apron.

Background

The cover plate is a part of the escalator and is arranged in a boarding area and a disembarking area, and because the power and transmission parts of the elevator are usually arranged below the cover plate, once the pedal fails, a pedestrian falls, so that a large casualty accident is often caused, and the recent elevator people-eating accident is frequently reported. The main reasons for various accidents are that the cover plate cannot be found in time after loosening, the cover plate can be operated with diseases for a long time, accidents are finally caused, and the elevator cannot be correctly installed after being overhauled, so that the accidents are also a great cause. Therefore, the loose condition of the cover plate is found in time and fed back, and a large number of accidents can be avoided.

Detailed Description

As shown in fig. 1 to 3, the escalator cover plate with a loosening warning function comprises a top plate 1 and a bottom plate 2, wherein a support rib 3 and an insulating filler 4 are arranged between the top plate 1 and the bottom plate 2, and the insulating filler 4 is arranged at an edge installation part. In this embodiment, the cover plates are connected by the fastening screws 6, the fastening screws 6 include screw heads 61 and screw rods 62, the upper portions of the screw rods 62 are provided with conductive trigger sleeves 63, the trigger sleeves 63 are tubular, the trigger sleeves 63 are fixedly connected with the screw rods and/or the screw heads, and the outer diameter is smaller than the outer size of the screw heads. The top plate 1 and the bottom plate 2 are provided with mounting holes at the positions where the screws are mounted, and the insulating filling body 4 is provided with through holes 5 corresponding to the positions of the screws. The through hole 5 is sequentially provided with a countersunk portion 51 and a triggering portion 52 from top to bottom, wherein the inner diameter of the countersunk portion corresponds to the external dimension of the screw head, and the inner diameter of the triggering portion corresponds to the outer diameter of the triggering sleeve 63. Each through hole is correspondingly provided with a group of conducting strip groups 7, the conducting strip groups 7 are fixedly installed in the insulating filling body 4 and comprise a first conducting piece 71 and a second conducting piece 72, as shown in fig. 4, the inner end part of the first conducting piece 71 is a first trigger piece 711, the outer end part of the first conducting piece is a first contact 712, the inner end part of the second conducting piece 72 is a second trigger piece 721, the outer end part of the second conducting piece 72 is a second contact 722, the first trigger piece 711 and the second trigger piece 721 are located in the trigger part 52, the two trigger pieces are oppositely arranged and are in an inverted 'eight' shape, and the first contact 712 and the second contact 722 extend out of the insulating filling header 4 and are communicated with each other.

When the cover plate is installed, the fastening screw 6 is screwed down to be fixed, at the moment, the trigger sleeve 63 is in contact with the first trigger piece and the second trigger piece, the mounting hole of the top plate 1 can be sealed by the plug piece, the screw is prevented from being exposed, the first contact and the second contact are connected into the trigger circuit, the trigger circuit can trigger the related control mechanism to control the escalator motor to stop and give out sound and light alarm, and under the normal state, because the trigger sleeve 63 is in contact with the first trigger piece and the second trigger piece, the first contact and the second contact are conductive, and the trigger circuit is in a communicated state. When the cover plate is loosened, two situations may occur:

1. loosening of the fastening screw: when the fastening screw is loosened, the screw can move upwards or be in a non-horizontal state, and the change of the two positions can cause the trigger kit to be separated from the trigger sheet, so that the first contact and the second contact are electrically connected and disconnected, the trigger circuit is in a disconnected state, the control mechanism is triggered, the escalator motor is controlled to stop, and sound and light alarm is accompanied.

2. The cover plate is integrally loosened: when the cover plate is integrally loosened, the first contact and the second contact displace along with the cover plate and are separated from the trigger circuit, so that the trigger circuit is disconnected, the control mechanism is triggered, the escalator motor is controlled to stop, and sound and light alarm is accompanied.

The circuit and control method of the present invention can be realized by simple circuit connection and programming of the technical personnel in the field, the power supply also belongs to the common knowledge in the field, and the present invention is mainly used for protecting the mechanical device, so the present invention does not explain the control method and circuit connection in detail.
