Background
At present, the opening and closing of the car stopping fence of the mine inclined roadway are operated by a hitter, the car stopping fence is in a real-time state, a driver of the elevator cannot know the car stopping fence by himself or herself, the driver can only inform the car stopping fence through the hitter, safety mainly depends on the working state and the responsibility of the hitter, once the state of the hitter is poor or the responsibility is not strong, an error message is sent, the driver of the elevator cannot judge, and safety accidents can be caused by sending out a car according to instructions provided by the hitter.
Disclosure of Invention
The utility model aims at above-mentioned situation, let all staff in the scene can both accurately learn the real-time status on traffic fencing in actual operation, reduce the elevator driver to the dependence of coupler worker, the elevator driver can independently judge the traffic fencing switching condition, has been equivalent to a heavy safety protection more. Simple installation, simple structure, and is practical, reliable and safe.
In order to achieve the above object, the present invention provides a method for manufacturing a semiconductor device, comprising: the sound-light alarm device for the car stop fence structurally comprises a monitoring sensing component and a sound-light alarm which are in communication through a cable.
The monitoring induction assembly comprises an installation base, a u-shaped fixing bolt, an induction switch, a switch bracket, a reflective sheet, a protective cover and the like. The inductive switch can be a contact type or a non-contact type, and the contact type inductive switch uses a travel limit switch and is close to the car stop rail beam; the non-contact inductive switch can be a photoelectric mirror surface feedback inductive switch, a photoelectric diffuse reflection inductive switch and a magnetic induction switch, and a certain distance is reserved between the non-contact inductive switch and the beam of the car stopping fence, so that the non-contact inductive switch is in charge of acquiring real-time opening and closing state signals of the car stopping fence and sending the acquired signals to the audible and visual alarm in time.
The audible and visual alarm is responsible for receiving the current signal that inductive switch sent, judges and distinguishes, sends corresponding instruction, and the action of control inside contactor sends audible and visual warning signal, tells the field work personnel.
The audible and visual alarm is in a normal mode when the stop fence is completely closed and does not send audible and visual signals. Only when the car stopping fence is not closed or the car stopping fence is in an open state and loses the protection effect, the car stopping fence enters a working mode and can send out sound and light warning signals.
Between the normal mode and the working mode of the audible and visual alarm, the internal contactor acts according to the current signal provided by the inductive switch to realize autonomous switching without human participation.
Has the beneficial effects.
The utility model relates to a sound-light alarm device for car stopping fence, simple structure realizes easily, through the switching state on real-time supervision car stopping fence, provides correct information to all staff in the scene by audible-visual annunciator, and the lifting machine driver can directly acquire the switching state on car stopping fence not through the hitter, has avoided because the work error of hitter, and the lifting machine driver sends out the possibility that causes the incident according to the wrong instruction. The working strength of the grappler is reduced, the hidden danger is eliminated, and the safety of inclined roadway transportation is powerfully guaranteed.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to all the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The present invention will be described in detail below with reference to fig. 1, 2, and 3.
The sound-light alarm device for the vehicle barrier structurally comprises a monitoring induction component 9 and a sound-light alarm 3.
The monitoring sensing assembly 9 comprises a mounting base 11, a u-shaped fixing bolt 12, a photoelectric feedback sensing switch 20, a sensing switch bracket 15, a reflector 22, a protective cover 26 and the like.
The mounting base 11 is mounted on the upright post 10 of the car-stopping fence by using a u-shaped fixing bolt 12 and a fixing nut 13, and the height can be adjusted.
The inductive switch bracket 15 is mounted on the monitoring inductive component mounting base 11 by an adjusting bolt 16 and a fixing nut 17, and the left and right stroke distance can be adjusted.
The photoelectric feedback inductive switch 20 is divided into an upper part and a lower part, which are both installed on the inductive switch bracket 15 by a limit nut 19 and a fixing nut 18, the reflector 22 is fixed on the cross beam 21 of the car stopping fence by self-tapping screws or nail-free glue, and the specific position is the position right opposite to the inductive switch head when the cross beam 21 of the car stopping fence is completely closed.
The upper photoelectric feedback inductive switch 20 and the lower photoelectric feedback inductive switch 20 work independently and are responsible for monitoring the real-time opening and closing states of the car stopping fence 8 and sending real-time signals to the audible and visual alarm 3, and when one of the two switches fails, the other switch does not work normally.
When the photoelectric feedback inductive switch 20 is normally closed on the vehicle stopping rail 8, the reflector 22 faces the inductive switch, the inductive switch 20 keeps a normal state and sends a corresponding signal to the audible and visual alarm 3, the audible and visual alarm 3 makes a judgment according to the received signal, the internal contactor does not act, no sound and light signal is sent, and the device is in a normal mode.
Photoelectric feedback inductive switch 20 is not closed well or when being opened by the hitter and other people at car stopping fence 8, reflector panel 22 breaks away from inductive switch 20 induction area, trigger inductive switch 20 action and get into operating condition, inductive switch 20 sends corresponding signal to audible-visual annunciator 3, audible-visual annunciator 3 makes the judgement according to received signal, the action of inside contactor, the device gets into operating mode, send out sound and light signal, inform all on-the-spot staff that car stopping fence 8 has been opened, lose the guard action, the staff starts lifting machine 1 according to actual conditions, mine car 6 transports the operation through car stopping fence 8.
After the mine car 6 passes through the car stopping fence 8, a hitter closes the car stopping fence 8, the reflective sheet 22 enters the sensing area of the inductive switch 20, the inductive switch 20 returns to the normal state, the audible and visual alarm 3 automatically enters the normal mode, and the audible and visual alarm is stopped.
In addition to the features described in the specification, are known to those skilled in the art.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
