Description
Technical field
The utility model relates to a kind of anti-pinch of induction automatically emergency staircase, belongs to elevator technology field.
Background technology
Existing elevator, the anti-pinch of car door normally, by infrared ray, the first-class sensing apparatus of making a video recording, detects between car door and has after object, the drive motor of controlling device for doors control car door stops car door mobile.When above-mentioned sensing apparatus breaks down, or because collection signal is when unintelligible, can cause pinch resistant functionality malfunctioning, elevator occurs crush people's accident.
Summary of the invention
The purpose of this utility model is: a kind of anti-pinch of induction automatically emergency staircase is provided, as elevator anti-pinch additional function, improves the safety factor of elevator.
The technical solution of the utility model: include doorframe, be provided with slideway in doorframe bottom, in slideway, be provided with pulley, on slideway, be provided with car door, be provided with drive motor on doorframe, feed belt connects drive wheel, drive wheel connects rotating band and flower wheel, on rotating band, connect hanger, hanger connects car door, and hanger hangs on door track; After the transmission shaft coupling torque inductor of drive motor, connect feed belt, moment inductor connects signal amplifier again, signal amplifier connection door control setup, and controlling device for doors control signal wire is connected to drive motor.
Above-mentioned automatic induction anti-pinch emergency staircase, on the axle of described moment inductor, both sides are provided with locating piece, on the turning cylinder of feed belt and the transmission shaft of drive motor, be respectively equipped with the positioning groove coordinating with locating piece, be provided with positioning screw hole in positioning groove side, above locating piece, be provided with positioning screw hole.
The beneficial effects of the utility model: car door of the present utility model by arranging moment inductor on drive motor, gather the turn signal of drive motor, when car door is clamped after object, the rotating torque of drive motor changes, controlling device for doors can stop drive motor in time, and Accident prevention further worsens.In order to facilitate installation and the replacing of moment inductor, adopt the quick connection mode of locating piece and positioning groove, moment inductor is stuck between drive motor and two axles of belt pulley, then screw is fixing.And without connections such as flanges, avoid installing while replacing and also need to remove belt pulley and motor could be changed.The utility model can be the in the situation that of existing anti-pinch equipment malfunction, prevents that car door from crushing people's accident deterioration, can be used as elevator anti-pinch accessory equipment and use.

Detailed description of the invention
Embodiment 1 of the present utility model: make doorframe 1, in doorframe 1 bottom, slideway 4 is set, in slideway 4, be provided with pulley 8, on slideway 4, be provided with car door 2, be provided with drive motor 3 on doorframe 1, feed belt 10 connects drive wheel 11, drive wheel 11 connects rotating band 12 and flower wheel 13, on rotating band 12, connect hanger 14, hanger 14 connects car door 2, and hanger 14 hangs on door track 15; After the transmission shaft coupling torque inductor 5 of drive motor 3, connect feed belt 10, moment inductor 5 connects signal amplifier 6 again, signal amplifier 6 connection door control setups 7, and controlling device for doors 7 control signal wires are connected to drive motor 3.
For easy for installation, as shown in Figures 2 and 3, on the axle of moment inductor 5, both sides make locating piece 9, on the turning cylinder of feed belt 10 and the transmission shaft of drive motor 3, be respectively equipped with the positioning groove 16 coordinating with locating piece 9, produce positioning screw hole 17 in positioning groove 16 sides, above locating piece 9, produce positioning screw hole 17.Moment inductor 5 is from top to bottom prevented, locating piece 9 is stuck in positioning groove 16, then fixing by the screw in positioning screw hole 17.
When work, drive motor 3 drives feed belt 10 and drive wheel 11 to rotate, pull rotating band 12, car door 2 is moved, moment inductor 5 detects the rotating torque of drive motor 3, in the time that the rotating torque of drive motor 3 changes, illustrating between car door 2 has had object or person body to be jammed, now moment inductor 5 sends signal to controlling device for doors 7 by signal amplifier 6, controlling device for doors 7 stops in time drive motor 3 and works, the Clamping force that prevents car door 2 strengthens, and causes the further deterioration of accident.
