In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides an elevator sedan-chair door striking protection device, includes sedan-chair door plant, strengthening rib, spacing backplate, deformation safety switch and deformation detection switch, the welding has two strengthening ribs on the sedan-chair door plant by the way, spacing backplate is installed to the ditch inslot of sedan-chair door plant, the internally mounted of strengthening rib has deformation safety switch and deformation detection switch, and deformation safety switch's bottom contact extends the strengthening rib directional spacing backplate.
Furthermore, the deformation detection switch is connected to an elevator control system through a cable, and the elevator control system is respectively connected to the voice broadcasting system and the building BA system.
Further, the deformation safety switch is connected in series into a safety loop of the elevator system.
Further, the deformation detection switch may be a correlation photoelectric or magnetic induction switch.
Compared with the prior art, the beneficial effects of the utility model are as follows:
in summary, the following steps: this elevator sedan-chair door striking protection device, deformation detection switch judge the deformation of door plant, and deformation detection switch gives elevator control system with signal transmission, and control system control voice broadcast system carries out the action of voice prompt stopping the door plant striking to personnel in the car, receives deformation detection switch signal for a long time like the system, explains that the sedan-chair door causes permanent damage. At this time, the elevator control system outputs the information to the BA system of the building to inform relevant persons in time. Receive the striking action and when deformation can cause the potential safety hazard to elevator normal operating at the sedan-chair door plant, the deformation safety switch of dress in the strengthening rib can touch spacing backplate, and elevator system safety circuit breaks off, prevents that the elevator from causing the injury to personnel in elevator and the sedan-chair because of the deformation of sedan-chair door plant and the layer door gear in the well bumps in the continuation operation process.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, an elevator sedan-chair door striking protection device, including sedan-chair door plant 1, strengthening rib 2, spacing backplate 3, deformation safety switch 4 and deformation detection switch 5, the welding has two strengthening ribs 2 on the sedan-chair door plant 1 by the way, can increase the intensity of sedan-chair door plant 1, spacing backplate 3 is installed to the ditch inslot of sedan-chair door plant 1, the internally mounted of strengthening rib 2 has deformation safety switch 4 and deformation detection switch 5, utilize the principle of sharp correlation to judge the deformation of door plant, this switch can be correlation photoelectricity, also can be magnetic induction switch.
Referring to fig. 4, a deformation detection switch 5 is connected to an elevator control system through a cable, the elevator control system is respectively connected to a voice broadcasting system and a building BA system, the voice broadcasting system and information provided for the building BA system are indirectly controlled through the deformation detection switch 5, the deformation detection switch 5 transmits a signal to the elevator control system, the control system controls the voice broadcasting system to perform voice reminding on personnel in a car to stop the behavior of impacting a door panel, if the system receives a deformation detection switch signal for a long time, which indicates that a car door is permanently damaged, at the moment, the elevator control system outputs the information to the building BA system and timely informs related personnel, a bottom contact of the deformation safety switch 4 extends out of a reinforcing rib 2 to point to a limiting protection plate 3, the deformation safety switch 4 is connected into a safety loop of the elevator system in series, when the door panel is impacted and deformed to cause potential safety hazards to normal operation of the elevator, the deformation safety switch 4 arranged in the reinforcing rib 2 can touch the limiting protection plate 3, the safety loop of the elevator control system is disconnected, and the elevator is prevented from being injured by the elevator and personnel in the elevator due to collision between the deformation of the car door plate 1 and a landing door device in a well in the continuous operation process.
When the sedan-chair door is too big by the striking dynamics, because clearance is less between elevator sedan-chair door and the layer door, make sedan-chair door 1 make elevator sedan-chair door and elevator layer door bump after seriously protruding outside the elevator shaft. As shown in fig. 2 deformation safety switch 4 sets up behind the vertical strengthening rib 2 of sedan-chair door plant 1, and deformation safety switch 4 cluster goes into elevator system safety circuit, receives strong impact back when the sedan-chair door, and deformation safety switch 4 moves after touchhing spacing backplate 3, and elevator safety circuit is timely moved, and the system is stopped promptly to the elevator, prevents that elevator sedan-chair door and elevator layer door from colliding and plays the guard action to personnel in the car.
In summary, the following steps: this elevator sedan-chair door striking protection device, deformation detection switch 5 judge the deformation of door plant, and deformation detection switch 5 gives elevator control system with signal transmission, and control system control voice broadcast system carries out pronunciation to personnel in the car and reminds and stop the action to the door plant striking, receives deformation detection switch 5 signal for a long time like the system, explains that the sedan-chair door causes permanent damage. At this time, the elevator control system outputs the information to the BA system of the building to inform relevant persons in time. Receive the striking action and when deformation can cause the potential safety hazard to elevator normal operating at sedan-chair door plant 1, dress deformation safety switch 4 in strengthening rib 2 can touch spacing backplate 3, and elevator system safety circuit breaks off, prevents that the elevator from causing the injury to personnel in elevator and the sedan-chair because of sedan-chair door plant in deformation and the well of sedan-chair door plant collision of sedan-chair door plant 1 in continuing the operation process.
