Description
Technical field
The utility model relates to a kind of devices for preventing cover board from touching steam-cured room, belong to field of mechanical technique.
Background technique
Concrete is conserved after pouring, and currently used maintenance process is that natural curing is that steam is supported
Shield, steam curing is carried out by steam-cured room, and the concrete poured is delivered to steam-cured interior by production line in mold, into
It needs to open die cover plate before entering steam-cured room, if production line is still being run at this time, cover board will touch steam-cured room, cause cover board
With the damage of steam-cured room, accordingly, it is desirable to provide a kind of device for preventing cover board from touching steam-cured room.
Utility model content
The main purpose of the utility model is to provide a kind of device for preventing cover board from touching steam-cured room, photoelectric detection switch
When detecting the signal that die cover plate is opened, production line emergency stop switch is controlled by control circuit and is opened, production line emergency stop is made,
Avoiding production line from continuing to run causes die cover plate to touch steam-cured room, can effectively solve the problems in background technique.
A kind of device for preventing cover board from touching steam-cured room, including the photoelectric detection switch being set on steam-cured room, the photoelectricity
In control circuit of the detection switch access for controlling production line emergency stop route, the control circuit includes the detection being mutually in parallel
Circuit and execution circuit.
Further, the detection circuit includes photoelectric detection switch, and one end of the photoelectric detection switch and power supply are just
Extremely it is connected, is connected after the other end series relay A normally opened contact a of photoelectric detection switch with power cathode, photoelectric detection switch
Both ends be parallel with relay B control contact.
Further, the execution circuit includes relay B normally-closed contact, one end of the relay B normally-closed contact with
Positive pole is connected, after the other end of relay B normally-closed contact series connection reset button and relay A control contact with power cathode
It is connected, the both ends of the reset button are parallel with relay A normally opened contact b.
Further, the photoelectric detection switch is located at outside steam-cured chamber inlet at 3.5 meters, and the installation of photoelectric detection switch is high
Degree is equal to steam-cured chamber inlet height.
Relay A is powered after pressing reset button when utility model works, later relay A normally opened contact a and relay
Device A normally opened contact b is closed, and relay A is self-locking, and the emergency stop route for producing route at this time is connected to relay A control contact, emergency stop
Route is in closed state, and relay A persistently powers to optoelectronic switch, and optoelectronic switch is started to work, if optoelectronic switch detects
When die cover plate does not cover, photoelectric switching signal line is powered to relay B, and relay B normally-closed contact disconnects, and relay A is self-locking same
When cancel, relay A controls contact and disconnects, and emergency stop route disconnects, and whole assembly line stops working, and optoelectronic switch stops working,
Reset button is pressed again after only correcting need to be handled well at this time, can restore the above process.
Detailed description of the invention
Fig. 1 is the circuit diagram of the utility model control circuit.
In figure: 1, photoelectric detection switch；2, relay A normally opened contact a；3, relay B controls contact；4, relay A is normal
Open contact b；5, relay B normally-closed contact；6, reset button；7, relay A controls contact.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1, the present embodiment provides a kind of device for preventing cover board from touching steam-cured room, including being set on steam-cured room
Photoelectric detection switch, the photoelectric detection switch access in the control circuit for controlling production line emergency stop route, the control
Circuit includes the detection circuit and execution circuit being mutually in parallel.
Relay A is powered after pressing reset button when work, later relay A normally opened contact a and relay A normally opened contact
B is closed, and relay A is self-locking, and the emergency stop route for producing route at this time is connected to relay A control contact, and emergency stop route is in and closes
Conjunction state, relay A persistently power to optoelectronic switch, and optoelectronic switch is started to work, if optoelectronic switch detects die cover plate not
Gai Shi, photoelectric switching signal line are powered to relay B, and relay B normally-closed contact disconnects, and relay A is self-locking to be cancelled simultaneously, relay
Device A controls contact and disconnects, and emergency stop route disconnects, and whole assembly line stops working, and optoelectronic switch stops working, and only needs to handle at this time
Reset button is pressed again after good correcting, can restore the above process.
Further, the detection circuit includes photoelectric detection switch, and one end of the photoelectric detection switch and power supply are just
Extremely it is connected, is connected after the other end series relay A normally opened contact a of photoelectric detection switch with power cathode, photoelectric detection switch
Both ends be parallel with relay B control contact.
Further, the execution circuit includes relay B normally-closed contact, one end of the relay B normally-closed contact with
Positive pole is connected, after the other end of relay B normally-closed contact series connection reset button and relay A control contact with power cathode
It is connected, the both ends of the reset button are parallel with relay A normally opened contact b.
Further, the photoelectric detection switch is located at outside steam-cured chamber inlet at 3.5 meters, and the installation of photoelectric detection switch is high
Degree is equal to steam-cured chamber inlet height.
It is above that certain exemplary embodiments of the utility model are only described by way of explanation, undoubtedly, for
Those skilled in the art can be with a variety of different without departing from the spirit and scope of the utility model
Mode is modified described embodiment.Therefore, above-mentioned attached drawing and description are regarded as illustrative in nature, and should not be construed as
Limitation to the utility model claims protection scope.
