Abstract
This utility model discloses the cover plate collapse safety device of a kind of escalator; including photoswitch and multiple safe device for ejecting; safe device for ejecting is formed by controlling Magnet, spring control device and main protection; photoswitch is arranged on below the cover plate of escalator, by with coil and fixed magnet phase separation.Fixed magnet and control Magnet one_to_one corresponding, fixed magnet controls whole safe device for ejecting by controlling Magnet.Spring controls device and is connected to main protection; main protection is a rectangle iron block; the rear end of main protection controls device with spring and is connected; recessed grain part between centre and the leading portion of main protection is connected with controlling Magnet; and retrained by controlling Magnet; the front end of main protection can move forward and backward, and can hold cover plate when stretching out.Once cover plate subsides, and ambient light is irradiated to light and establishes by cable, thus connects circuit, gives and controls one signal of Magnet, thus safe device for ejecting is released, and effectively prevents the generation of peril.
Description
Technical field
This utility model relates to the safety guard of a kind of escalator, and particularly a kind of cover plate for escalator is anti-to collapse
Safety 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.
Utility model content
In order to overcome the defect of prior art, the purpose of this utility model patent is to provide one and can transport at escalator
The anti-cover plate of escalator that during row, 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, this utility model patent is by the following technical solutions:
The anti-safety device that collapses of cover plate for escalator of the present utility model, ejects dress including photoswitch and multiple safety
Putting, safe device for ejecting is formed by controlling Magnet, spring control device and main protection.Photoswitch is arranged on escalator
Cover plate below, by interacting with coil and fixed magnet, thus control each safe device for ejecting.Control Magnet to install
Stage casing groove position below main protection.Spring controls device and connects main protection.Main protection be one rectangular
Shape iron block, the rear end of main protection controls device with spring and is connected, the recessed grain portion between centre and the leading portion of main protection
Dividing and be connected with control Magnet, and controlled by controlling Magnet, the front end of main protection can move forward and backward, and holds and subside when stretching out
Cover plate.Spring controls device and utilizes the elastic force of self to eject by main protection.When cover plate subsides, main protection ejects
Cover plate is held from below.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.

Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is illustrated, to describe technology of the present utility model in detail
Scheme.The anti-safety device that collapses of cover plate for escalator of the present utility model, including photoswitch 1 and multiple safe device for ejecting,
Safe device for ejecting is formed, as shown in Figure 1 by controlling Magnet 2, spring control device 3 and main protection 4.Photoswitch 1 is pacified
It is contained in below the cover plate of escalator, by interacting with coil and fixed magnet, thus controls each safe device for ejecting.
Control Magnet 2 and be arranged on the groove position in the middle of below main protection 4 and between leading portion.Spring controls device 3 and connects main guarantor
Protection unit 4.Spring controls device 3 and utilizes the elastic force of self to eject by main protection 4, as shown in Figure 2.Main protection 4 is
One rectangle iron block, the rear end of main protection is connected with spring assembly 3, the recessed grain in the middle of main protection and between leading portion
Part is connected with controlling Magnet 2, and is controlled by controlling Magnet 2, and the front end of main protection can move forward and backward, permissible when stretching out
Hold the cover plate subsided.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
Becoming 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 preferred embodiment of the present utility model, this utility model is not restricted to the described embodiments, right
For those skilled in the art, in without departing from this utility model institute on the premise of, this utility model can also be made some
Plant modification and improvement, within these improvement and modification all should be included in the protection domain required by this utility model.
