Abstract
The invention discloses a safety device for preventing collapse of a cover plate of an escalator. The safety device comprises an optoelectronic switch and a plurality of safe ejection devices, wherein the safe ejection devices comprise control magnets, spring control devices and main protection devices; the optoelectronic switch is mounted below the cover plate of the escalator; all the safe ejection devices are controlled through the interaction of coils and fixed magnets; the fixed magnets and the control magnets are in one-to-one correspondence; the fixed magnets control all the safe ejection devices through the control magnets; the spring control devices are connected with the main protection devices; the main protection devices are rectangular iron blocks; the back ends of the main protection devices are connected with the spring control devices; groove parts between the middle parts and the front sections of the main protection devices are connected with the control magnets, and are restrained by the control magnets; and the front ends of the main protection devices can move back and forth, and can drag the cover plate when stretching out. According to the safety device, once the cover plate collapses, external light irradiates the optoelectronic switch, a circuit is energized, a signal is sent to the control magnets, the safety ejection devices are released, and dangerous accidents are effectively prevented.
Description
Technical field
The present invention relates to the safety guard of a kind of escalator, particularly a kind of anti-safety that collapses of cover plate for escalator
Device.
Background technology
Escalator is now widely available in public places such as market, railway stations, brings convenience to people at escalator
While, gradually send out to currently use escalator also brings and much bother or cause great casualties, automatically hold up using
During ladder, it some times happens that escalator upper and lower cover plates breaks down, it is still within, in the middle of use, not finding.?
Do not recognize problem, still use, often result in the biggest harm.Fix upper and lower cover plates device when escalator to go out
Now loosen or completely cisco unity malfunction time, personnel step in ignorant situation, and cover plate is prominent to subside, in order to avoid so
The generation again of thing, thus design a safety device preventing cover plate for escalator from subsiding.
Summary of the invention
In order to overcome the defect of prior art, the purpose of patent of the present invention is to provide one can be in escalator operation mistake
The anti-cover plate of escalator that in journey, upper and lower cover plates subsides suddenly to prevent cover plate from falling down in time subsides safety device.
In order to achieve the above object, patent of the present invention is by the following technical solutions:
The anti-safety device that collapses of the cover plate for escalator of the present invention, including photoswitch and multiple safe device for ejecting, safe bullet
Go out device and formed by controlling Magnet, spring control device and main protection.Photoswitch is arranged under the cover plate of escalator
Side, by interacting with coil and fixed magnet, thus controls each safe device for ejecting.Control Magnet and be arranged on main protection
Groove position in stage casing below device.Spring controls device and connects main protection.Main protection is a rectangle iron block, main
The rear end of protection device controls device with spring and is connected, the recessed grain part between centre and the leading portion of main protection and control magnetic
Ferrum connects, and is controlled by controlling Magnet, and the front end of main protection can move forward and backward, and holds the cover plate subsided when stretching out.Bullet
Spring controls device and utilizes the elastic force of self to eject by main protection.When cover plate subsides, main protection ejects from lower Orly
Live cover plate.When cover plate normally works, main protection is hidden in the inside, does not affect normal work.
Photoswitch includes power supply and photoelectric sensor.Photoswitch and multiple coil, the composition parallel connection of multiple fixed magnet
Circuit.Fixed magnet and control Magnet one_to_one corresponding, fixed magnet is by controlling Magnet and then controlling safe device for ejecting.
Whole control system is by photoswitch, multiple fixed magnet, multiple coil, multiple spring and multiple control group of magnets
Become, control Magnet and pass through spring and magnetic, with fixed magnet phase separation.
Accompanying drawing explanation
Fig. 1 is the anti-safety apparatus structure schematic diagram that collapses of cover plate for escalator of the present invention；
Fig. 2 is that cover plate for escalator of the present invention is prevented collapsing the safe device for ejecting structural representation of safety device；
Fig. 3 is that cover plate for escalator of the present invention is prevented collapsing the circuit diagram of safety device control system；

Detailed description of the invention
Preferable examples of the present invention will be described below in conjunction with the accompanying drawings, to describe technical scheme in detail.This
The anti-safety device that collapses of the cover plate for escalator of invention, including photoswitch 1 and multiple safe device for ejecting, safe device for ejecting
Formed, as shown in Figure 1 by controlling Magnet 2, spring control device 3 and main protection 4.Photoswitch 1 is arranged on escalator
Cover plate below, by interacting with coil and fixed magnet, thus control each safe device for ejecting.Control Magnet 2 to pacify
It is contained in the groove position in the middle of below main protection 4 and between leading portion.Spring controls device 3 and connects main protection 4.Spring
Controlling device 3 utilizes the elastic force of self to eject by main protection 4, as shown in Figure 2.Main protection 4 is a rectangle ferrum
Block, the rear end of main protection is connected with spring assembly 3, the recessed grain part in the middle of main protection and between leading portion and control magnetic
Ferrum 2 connects, and is controlled by controlling Magnet 2, and the front end of main protection can move forward and backward, and can hold the lid subsided when stretching out
Plate.The main protection 4 ejected holds the cover plate 9 of whereabouts from below, thus prevents cover plate from subsiding.
Photoswitch 1 includes power supply and photoelectric sensor.Photoswitch 1 respectively with multiple coils, multiple fixed magnet 5 groups
Become parallel circuit.Each fixed magnet 5 is corresponding with controlling Magnet 2 one_to_one corresponding, and fixed magnet 5 is by controlling Magnet 2 and then control
Make safe device for ejecting.
Whole control system is by photoswitch 1, multiple fixed magnet 5, multiple coil, multiple spring and multiple control Magnet
2 compositions.Fixed magnet 5 by spring and magnetic, and controls Magnet 2 phase separation 2, as shown in Figure 3.
Under normal circumstances, cover plate normally works when not occurring subsiding whole system, and spring controls device 3 and is in compression
State, and be connected with main protection 4.In now main protection 4 is hidden in whole device, referred to as off working state, such as Fig. 4
Shown in.Once cover plate subsides, and ambient light is irradiated to photoswitch 1, thus connects circuit, gives and controls one signal of Magnet, controls
Magnet 2 is started working, and controls Magnet 2 and down moves, discharges safe device for ejecting, and spring controls device 3 and utilizes the elastic force of self,
Main protection 4 is ejected, as it is shown in figure 5, the main protection 4 ejected holds the cover plate 9 of whereabouts from below.Thus from following
Hold cover plate 9, it is to avoid cover plate landing.
By the time, after the cover plate collapsed is repaired, main protection returns in situ.Control system can utilize and fix magnetic
The spring handle that ferrum 5 is connected controls Magnet 2 and moves on to the groove of main protection 4.
The foregoing is only the preferred embodiments of the present invention, the present invention is not restricted to the described embodiments, for industry
For technical staff, in without departing from institute of the present invention on the premise of, the present invention can also make several modification and improvement, these
Within improvement and modification all should be included in protection domain of the presently claimed invention.
