Fig. 1 is a schematic structural view of an apparatus for improving safety of an elevator according to the present invention.
Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1
The embodiment discloses a device for improving elevator safety. The device mainly comprises the following parts: double-deck structure sedan-chair door, electric capacity detected value, electric capacity value analysis appearance, elevator master control, elevator door machine, car communication board.
The double-layer structure elevator door is connected with a capacitance detector, the capacitance detector is connected with an elevator main control board, and the elevator main control board is respectively connected with an elevator door motor and an elevator car communication board;
the capacitance detector is arranged in the elevator car and moves along with the elevator car; the capacitance value analyzer is installed in the elevator control cabinet. Illustratively, the capacitive detector is mounted at the top or bottom of the elevator car, and the location of the capacitive detector is not limiting to the present solution.
The capacitance detector is connected with a capacitance value analyzer in the elevator control cabinet along with the hoistway cable.
The double-layer structure car door adopts double-layer structure steel, and the stability and the safety of the structure of the car door are mainly ensured by the car door at one side close to a hoistway in the double-layer structure car door, and the strength, the hardness and the like of the double-layer structure car door all meet the national standard requirements; the door near the car is preferably made of thinner steel, and the door near the car is insulated. The double-layer structural steel is adopted for the car door, after direct current is conducted to the car door close to one side of the hoistway, the whole car door forms a loop, and a capacitor is formed by adopting the double-layer structural steel of the car door. C=u/d, where C represents a capacitance value between the double-layered structural steels, U is a voltage value added between the double-layered structural steels, d is a distance between the double-layered structural steels, and when the car door is pressed or leaned against with a certain force, the distance between the double-layered structural steels of the car door is reduced, and the capacitance value between the two plates is also changed correspondingly.
When a passenger extrudes the car door, the distance between the two-layer structural steel of the car door is reduced, the corresponding capacitance value is increased, the capacitance value is detected by using the capacitance detector, the detected capacitance value is transmitted to the capacitance value analyzer, and the capacitance value analyzer analyzes the capacitance value. Under normal conditions, the capacitance value analyzer does not transmit signals to the elevator main control board, and if the capacitance value is larger than a preset judgment threshold value, the capacitance value analyzer transmits signals to the elevator main control board. If the elevator is in the running process, the elevator main control board sends out a safety prompt through the car communication board until the elevator can not receive the signal sent by the capacitance value analyzer; if the elevator is in a stop-and-wait door-opening state, the elevator main control board delays door opening by controlling the elevator door motor, and sends a safety prompt through the car communication board until a signal sent by the capacitance value analyzer is not received.
Example two
The embodiment discloses a device for improving the safety of an elevator, and particularly discloses a double-layer structure elevator door, wherein the double-layer structure elevator door is made of double-layer structure steel, the distance between the two layers is 30mm, wherein the elevator door is close to one layer of an elevator shaft and is designed according to the national standard, and the safety and the stability of the elevator door are mainly guaranteed; the thickness of the steel material is lower than the national standard at one layer close to the car, and one side close to the car is coated with an insulating layer for insulation treatment. The double-layer structure car door mainly has the effect of feeling the acting force of passengers on the car door, when passengers squeeze or lean against the car, the car door can deform, the distance between the two layers of car doors is reduced, the plasticity of the plate is strong, and the plate can be quickly restored to the original state after being stressed.
The outer door plate of the car door close to one side of the hoistway is supplied with 15v voltage, at this time, the whole car door forms a loop, and at this time, according to c=u/d, the capacitance value between the double-layer structural steels of the car door is 0.5F. The capacitance detector monitors the capacitance value between the two plates of the car door in real time and transmits the capacitance value to the capacitance value analyzer. Under normal conditions, the capacitance value analyzer is not transmitted to the elevator main control board by signals, when passengers have larger acting force on the car door, the car door with the double-layer structure deforms, the distance between steel materials with the double-layer structure of the car door is reduced, and the capacitance value is increased. When the minimum distance between the steel plates of the double-layer structure of the elevator door is 25mm (in practice, the value can be determined according to experiments), and the capacitance is increased to 0.6F, the capacitance value analyzer sends a signal to the elevator main control board, and if the elevator is in the running process, the elevator main control board sends a safety prompt through the elevator car communication board until the signal sent by the capacitance value analyzer is not received; if the elevator is in a stop-and-wait door-opening state, the elevator main control board delays door opening by controlling the elevator door motor, and sends a safety prompt through the car communication board until a signal sent by the capacitance value analyzer is not received.
The above examples are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above examples, and any other changes, modifications, substitutions, combinations, and simplifications that do not depart from the spirit and principle of the present invention should be made in the equivalent manner, and the embodiments are included in the protection scope of the present invention.
