Abstract
Disclosed is a speed measuring device of an escalator mainframe. A photoelectric detector (2) is mounted on the mainframe through a mainframe speed measuring photoelectric support (1). Evenly-distributed holes on the mainframe is used for positioning by means of approaching fixing intelligent light, and accordingly excessively high or excessively low speed of the mainframe is prevented, when the excessively high or excessively low speed of the mainframe reaches a certain extent, an escalator stops to prevent accidents, and operation safety of the escalator is increased.
Description
Technical field
The present invention relates to a kind of
The speed measuring device of staircase main frame.
Background technology
Tachogenerator is positioned at the two ends of elevator, when elevator finds that for a long time the data of sensor are constant, elevator can speed fall very low, with brownout! When having the people to pass through, elevator speed becomes normal speed at once, and the people is delivered to the destination.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of speed measuring device of staircase main frame is provided.
The present invention is achieved through the following technical solutions goal of the invention:
A kind of speed measuring device of staircase main frame is installed detection photoelectricity by the main frame photoelectric support that tests the speed on described main frame.
Beneficial effect:
Utilize well-distributed hole on main frame, locate with approaching fixedly intelligent optical, prevent that main frame speed is excessive or too small, excessive or too small when surpassing certain amplitude when main frame, elevator will auto-stop, avoids the generation of accident, increase staircase Operation safety.
Description of drawings
Fig. 1 is the integral structure schematic diagram.
Fig. 2 is the partial enlarged drawing of Fig. 1.
The specific embodiment
A kind of speed measuring device of staircase main frame is installed and is surveyed photoelectricity 2 by the main frame photoelectric support 1 that tests the speed on described main frame.Utilize well-distributed hole on main frame, locate with approaching fixedly intelligent optical, prevent that main frame speed is excessive or too small, excessive or too small when surpassing certain amplitude when main frame, elevator will auto-stop, avoids the generation of accident, increase staircase Operation safety.
Claims (1)
1. the speed measuring device of a staircase main frame is characterized in that: install and survey photoelectricity (2) by the main frame photoelectric support (1) that tests the speed on described main frame.
