Detailed Description

An elevator is a motor-powered vertical lift equipped with a box-like car for carrying passengers or cargo in a multi-story building to serve a fixed lifting device at a predetermined floor. A vertical lift elevator has a car that travels between at least two vertical rows of rigid guide rails. The size and the structural form of the car are convenient for passengers to access or load and unload goods.

The elevator hall door, also called elevator landing door, is generally composed of door, guide rail frame, pulley, slide block, door frame and sill. The opening and closing of the landing door are realized through the door opening blade arranged on the car door, each landing door is provided with a door lock, after the landing door is closed, the mechanical lock hook of the door lock is meshed, meanwhile, the landing door and the car door are closed through the electrical interlocking contact, the elevator control loop is switched on, and the elevator can be started to run at the moment. The elevator layer door has a fireproof effect in a building and is used for dividing fireproof subareas. The elevator landing door is a safety switch of the car door, and the situation that the door is not safely closed in place or the elevator cannot normally run in a locked state can be guaranteed.

The existing anti-collision of the elevator hall door generally adopts infrared detection, and when the infrared detection detects that people or objects approach, the door can be opened or closed or the operation of the elevator is stopped to protect the safety of passengers. But the judgment of the fault can not be carried out after the elevator hall door is collided and has the fault, so that the potential safety hazard of the elevator is caused.

The embodiment of the application provides an elevator hall door impact detection device, which comprises a collision sensor and a processor, wherein the collision sensor is connected with the processor, and the collision sensor is arranged on a hall door. The collision sensor is used for detecting collision strength and converting the collision strength into an electric signal to be transmitted to the processor, the processor determines that the collision strength exceeds a set threshold value, triggers a switch signal, transmits a detected result to a door control system of the elevator, transmits the detected result to a main control system of the elevator through the door control system of the elevator, and reports the detected result to an elevator monitoring system, so that elevator maintenance personnel are informed to confirm and take corresponding protective measures.

The collision sensor may be fixed to the hall door by a mechanical structure, but the collision sensor can be fixed only at a specific position by the mechanical structure, resulting in a low degree of flexibility in the deployment of the collision sensor. Therefore, in some embodiments, the collision sensor is provided with a magnet, and the collision sensor is fixed on the hall door through the magnet, so that flexible arrangement of the collision sensor can be realized through the magnet fixing mode. In some embodiments, the fixation of the impact sensor may also be achieved by means of mechanical structural fixation and magnet cooperation.

The collision sensor can use 360CAS5-4, the action threshold value is 7 +/-1 g, the collision sensor can act on all frequency bands at any frequency point, and no resonance out-of-state phenomenon exists; the magnetic field is insensitive to strong magnetism, gravity field, electromagnetic radiation and the like; the interference and the restriction of the installation angle, the installation posture and the installation state are avoided; the brake pad is insensitive to vibration, bump, sudden braking, shaking and the like; is not sensitive to high-speed rotation, namely centrifugal force; the device can bear 1000g of acceleration overload and is not damaged; the collision detection is spherical collision detection, and blind spots and dead angles are avoided. The action life of 360CAS5-4 is more than 100 ten thousand times, and the working temperature is between minus 38 ℃ and minus 125 ℃; the static current is zero, and no power consumption exists in a non-action state; the acceleration sensor integrates sensing and an actuator into a whole, can sense an acceleration threshold value without a complex auxiliary circuit and a control unit, integrates a sensor and an actuator into a whole, can sense the acceleration threshold value without the complex auxiliary circuit and the control unit, and executes a switch action.

The elevator hall door impact detection device needs an external power supply to supply power, generally, the elevator hall door impact detection device is directly connected with the external power supply to supply power, but the direct connection of the external power supply needs to arrange an additional power line on the hall door, and under the condition that the hall door is impacted, a line is often easily damaged, so that the elevator hall door impact detection device loses power. Therefore, in some embodiments, referring to fig. 1, the hoistway door collision detection device is provided with a battery, and the stability of the hoistway door collision detection device can be improved by supplying power to the hoistway door collision detection device through the battery.

After detecting that the hoistway door is impacted by a heavy object, the elevator hoistway door impact detection device needs to transmit a signal to a door control system of the elevator, and generally adopts a signal wire mode to transmit the signal to the door control system of the elevator. Therefore, in some embodiments, referring to fig. 1, the hoistway door impact detection device is provided with a wireless communication module, and the signal of the hoistway door impact detection device is transmitted to the door control system of the elevator through the wireless communication module, so as to realize wireless transmission of the signal.

Since the source of the collision of the hoistway door is generally the elevator waiting room, in order to prevent the collision damage of the elevator hoistway door collision detection device, in some embodiments, the elevator hoistway door collision detection device is arranged on the side of the hoistway door close to the hoistway, so as to prevent the elevator hoistway door collision detection device from direct collision. The elevator hoistway is the space in which the car and counterweight or hydraulic cylinder plunger move, which is bounded by the bottom of the hoistway pit, the hoistway walls, and the hoistway roof. The stability of the hoistway door impact detection device can be improved by arranging the hoistway door impact detection device on one side of the hoistway door close to the hoistway.

In some embodiments, referring to fig. 1, a speaker and an indicator light are further disposed on the hoistway door impact detection device, the speaker can emit a sound signal to remind passengers of getting away from the hoistway door after the hoistway door is impacted, and the indicator light can emit a light signal to achieve an alarm effect. Through the cooperation of speaker and pilot lamp, can realize audible and visual alarm.

After the hoistway door collision detection device detects that the hoistway door is collided with the collision exceeding the threshold value, the hoistway door collision detection device is in a locking state, and in some embodiments, referring to fig. 1, a reset button is further arranged on the hoistway door collision detection device, and after a maintenance person checks that the hoistway door is not in a fault, the maintenance button can be pressed to reset the hoistway door collision detection device.
