fig. 3 is a schematic structural view of a handle unlocking limiting device of the emergency unlocking device with a locking function.
Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific examples:
referring to fig. 1 and 2, the emergency unlocking device with a locking function of the present invention includes a cover plate device 1, an indicator light and buzzer 2, an operating handle 3, a door opening sensor 4, a handle unlocking limiting device 5 and a detection switch 6.
The door opening sensor 4 is hidden at the back of the cover plate device, is invisible at the front, prevents malicious damage, and is connected with the door leaf of the cover plate device 1. The detection switch 6 is connected with the cab and controlled by the cab. The door opening sensor 4 and the detection switch 6 are respectively connected with the handle unlocking limiting device 5, and the handle limiting device 5 is controlled by the door opening sensor 4 and the detection switch 6 to lock or release the degree of freedom of the operating handle 3. The indicator light and the buzzer 2 are used for reminding the state of the operating handle of the passenger.
Referring to fig. 3, the handle unlocking limiting device is specifically composed of a lock rod 51, a locking electromagnet 53 and a holding electromagnet 54.
The locking lever 51 is rotatable about a pivot 52, and one end thereof is provided with a latch structure which engages with a connecting block of the operating handle when rotated to a locked state, thereby enabling the degree of freedom of the operating handle 3 to be locked or released. The other end of the lock rod 51 is provided with a guide hole, the locking electromagnet 53 is provided with a connecting rod 531, the connecting rod 531 is clamped in the guide hole, and the locking electromagnet 53 is connected with a return spring 532. When the locking electromagnet is powered on, the locking electromagnet moves rightwards, drives the connecting rod to push the locking rod 51 to rotate, and is reset through the reset spring when the power is lost. The holding electromagnet 54 is connected to a vertically extendable limiting rod 541, and the limiting rod 541 limits the rotation of the lock lever 51.
In the initial state, the door leaf of the cover plate device is closed, and the handle unlocking limiting device is in the unlocking state. At the moment, the lock rod is abutted to the right side of the limiting rod, the lock rod does not limit the degree of freedom of the operating handle, and the reset spring stretches.
When the door leaf of the cover plate device is opened, the door opening sensor is triggered, the control handle unlocking limiting device performs state switching, the electromagnet is kept powered to control the limiting rod to descend, the locking electromagnet is driven by restoring force of the reset spring to translate to drive the connecting rod to move, the locking rod rotates under the pulling of the connecting rod, the locking rod limits the degree of freedom of the operating handle, the handle unlocking limiting device is in a locking state, the detection switch is triggered to send a signal to the cab at the same time, the electromagnet is powered again, and the limiting rod is controlled to ascend. At the moment, the operating handle cannot be pulled, but the buzzer triggers to buzz, and the indicator light is in a waiting state to prompt a user that the use requirement of the equipment is responded.
After the cab receives the signal, the cab can communicate with passengers through talkback or automatically judge whether the use requirement of the emergency unlocking device is really met.
If the operation is allowed, after the cab sends an operation allowing signal through the detection switch, the electromagnet is kept powered to control the limiting rod to descend, then the locking electromagnet is powered to move horizontally, the connecting rod pushes the lock rod to rotate, the lock rod releases the degree of freedom of the operating handle, the handle unlocking limiting device is in an unlocking state, and the electromagnet is kept to control the limiting rod to ascend again. The indicator light is in a use state, and prompts passengers that the operation can be carried out.
And if the operation is not allowed, the handle unlocking limiting device keeps a locking state until the door leaf of the cover plate device is closed, and the handle unlocking limiting device restores to an unlocking state. The indicator light and the buzzer are extinguished.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above described embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
