Technical Field

The invention belongs to the technical field of elevator equipment, and particularly relates to an anti-pinch structure for an elevator and an anti-pinch method thereof.

Background

An elevator is a permanent transport device serving a number of specific floors in a building, the cars of which travel in at least two rigid tracks perpendicular to the horizontal or inclined at an angle of less than 15 ° to the vertical. There are also steps, where the tread plates are mounted on a track for continuous operation, commonly known as escalators or moving walkways. A fixed elevator apparatus serving a predetermined floor. The vertical lift elevator has a car that runs between at least two vertical rows of rigid guide rails or guide rails with an angle of inclination of less than 15 °. The size and the structural form of the car are convenient for passengers to access or load and unload goods. It is customary to use elevators as a generic term for vertical transport means in buildings, irrespective of their drive mode. Modern elevators are mainly composed of a traction machine (winch), guide rails, a counterweight, safety devices (such as a speed limiter, a safety gear, a buffer and the like), a signal control structure, a car, a hall door and the like. These parts are installed in the hoistway and machine room of the building, respectively. Most of existing elevators are prevented from being clamped through infrared induction or are prevented from being clamped through mechanical pressure induction, but the inspection effect of the two anti-clamping structures on thin and thin objects such as a child traction rope or a pet traction rope is very poor, and safety accidents are easily caused.

Disclosure of Invention

The invention aims to provide an anti-pinch structure and an anti-pinch method for an elevator, and solves the problems that most of existing elevators are anti-pinch through infrared induction or mechanical pressure induction, but the two anti-pinch structures have very poor inspection effects on thin objects such as a child traction rope or a pet traction rope and are easy to cause safety accidents.

The invention adopts the following technical scheme:

the utility model provides a prevent pressing from both sides structure for elevator, including layer door, car and control module, be equipped with the door plant on layer door and the car respectively, the door plant includes first door and second door, first door side is equipped with a plurality of recess, the recess inner wall is equipped with pressure measurement, second door side is equipped with the telescopic link, the telescopic link cooperatees with the recess, layer door top and bottom that are close to car one side are equipped with first proximity switch respectively, the top and the bottom of car cooperate with two first proximity switches respectively, the side of first door is equipped with the second proximity switch, pressure measurement, the telescopic link, first proximity switch and second proximity switch respectively with control module electric connection.

Furthermore, there are two grooves, and the two grooves are respectively located at the trisection of the first door.

Furthermore, the rod wall of the telescopic rod is made of brittle materials, and the brittle materials are made of ceramics.

An anti-pinch method for an anti-pinch structure of an elevator: when the second proximity switch detects that the first door and the second door are closed, the control module controls the telescopic rod to be inserted into the groove, the car ascends or descends, when the first proximity switch is separated from the car, the pressure detection device starts to work, if thin and thin objects such as ropes are clamped between the first door and the second door, two ends of each rope are blocked and move, when the ropes contact the telescopic rod and enable the pressure detection module to detect a set pressure value, the control module controls the car to stop emergently, and controls the car to return to the original layer door and open the door plate.

The invention has the advantages that: this a prevent pressing from both sides structure and prevent pressing from both sides method simple structure for elevator is to the infrared supplement of preventing pressing from both sides structure or machinery prevent pressing from both sides structure of tradition, and this structure is obvious to thin, thin article anti-pinch effect such as rope class, and is safer.
