Embodiment Construction

[0024] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0025] Such as figure 1 As shown, the present invention provides a mechanical pedal missing detection device, which detection device includes: a rotating shaft 10, and first rotating arms 11 and The second rotating arm 12 can drive the rotating shaft 10 to rotate when the extended end of the first rotating arm 11 is moved by force, and then the rotating shaft 10 drives the second rotating arm 12 to rotate. Similarly, the rotation of the second rotating arm 12 It is also possible to drive the first rotating arm 11 to rotate through the rotating shaft 10; the extended end of the first rotating arm 11 is provided with a contact roller 13, and the contact roller 13 is in rolling contact with the lower surface of the moving walkway pedal so that the seco...

Abstract

The invention provides a mechanical footboard loss detecting device and a passenger conveyor with the same. The footboard loss detecting device comprises a rotating shaft, a first rotating arm, a second rotating arm, a contact roller, a resetting mechanism and a sensor, wherein the contact roller is arranged at an extending end of the first rotating arm and is in rolling contact with the lower surface of a footboard of the passenger conveyor so that the second rotating arm is placed at a non-alarm position, the resetting mechanism comprises an elastic part for leading the second rotating arm to move to an alarm position, the sensor is arranged on the movement trace of the second rotating arm, and the second rotating arm contacts with the sensor when moving to the alarm position, so that the sensor generates a footboard loss alerting signal. The mechanical footboard loss detecting device continuously contacts with the lower surface of the footboard through the contact roller, when the footboard is lost, an empty space is generated at the position of the footboard, the contact roller is not pressed, the second rotating arm rotates to press the sensor under the action of spring force, and the sensor generates the footboard loss alerting signal, so that loss of the footboard can be timely detected.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a mechanical pedal loss detection device. In addition, the present invention also relates to a moving walk with the above-mentioned detection device. Background technique [0002] The mechanical pedal loss device is a device used to detect the loss of pedals in sidewalks. Most of the existing industries use photoelectric sensors to detect the pulses generated by the pedal ribs, but the reliability and stability of the sensors in this solution are not good. , which can easily lead to inaccurate test results. Contents of the invention [0003] The purpose of the present invention is to provide a mechanical pedal loss detection device and a moving walk with the detection device, so as to solve the technical problems of poor reliability and poor stability in the existing detection methods. [0004] To achieve the above object, according to one aspect of the present invention, a...
