The utility model provides a technical scheme that its technical problem adopted is: the alarm device for the running of the travelling crane comprises a door sill, a magnetic absorption switch and a photoelectric switch, wherein the door sill is arranged in the middle of the travelling crane, the magnetic absorption switch is arranged in the middle of the door sill and controls the door sill to be opened and closed, the magnetic absorption switch is connected with a door sill alarm, and the door sill alarm gives an alarm when the magnetic absorption switch is not closed;
photoelectric switches are oppositely arranged on two sides of the door sill and connected with a pedestrian alarm for monitoring the alarm when people go in and out of the bus.
The magnetic attraction switch is arranged at the position opposite to the magnetic attraction block on the fence, adsorbs the magnetic attraction block to close the fence, and is used for triggering the fence alarm to alarm when the stress magnetic attraction switch of the fence is disconnected with the magnetic attraction block.
Specifically, photoelectric switch includes photoelectric switch emission module and photoelectric switch receiving module, and photoelectric switch emission module installs on the rail of door hurdle one side, and photoelectric switch receiving module installs relatively on the rail of door hurdle opposite side for triggering pedestrian's alarm when photoelectric signal is blocked and report to the police.
Specifically, the door sill alarm adopts an audible and visual alarm for prompting that the door sill is not closed through light voice, and the pedestrian alarm adopts an audible and visual alarm for prompting that a person cannot drive through light voice.
The utility model discloses following beneficial effect has:
the utility model discloses a warning device of driving operation adopts and inhales magnetic switch AND gate fence alarm cooperation, monitors the switch condition of door fence, only need during the warning close the door fence can, do not need to park and maintain, influence work goes on, adopt photoelectric switch and pedestrian alarm cooperation, the monitoring has unmanned business turn over maintenance, can not drive when someone, guarantee personnel's safety, avoid the driver of driving a vehicle because of blindly under the condition of not knowing the reason to repair, use manpower sparingly and time, improve work efficiency.
Drawings
Fig. 1 is a schematic structural diagram of a warning device for driving operation.
In the figure: 1, driving a vehicle; 2-door fence; 3-fencing; 4-a magnetic attracting switch; 5-a photoelectric switch transmitting module; 6-photoelectric switch receiving module; 7-a doorsill alarm; 8-pedestrian alarm.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely further described in detail below with reference to the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the alarm device for driving operation comprises a driving vehicle 1, a door sill 2, a fence 3, a magnetic attraction switch 4, a photoelectric switch, a door sill alarm 7 and a pedestrian alarm 8, wherein the door sill 2 is installed in the middle of the driving vehicle 1, the magnetic attraction switch 4 is installed in the middle of the door sill 2, and the magnetic attraction switch 4 controls the opening and closing of the door sill 2.
The magnetic attraction switch 4 is connected with a door sill alarm 7, and the door sill alarm 7 gives an alarm when the magnetic attraction switch 4 is not closed; install rail 3 around driving 1 upper portion, rail 3's middle part is through round pin axle articulated door fence 2 one side, and the piece is inhaled to 2 opposite side mid-mounting of door fence magnetism, and the piece relative position is inhaled with magnetism to install on rail 3 and is inhaled magnetic switch 4, inhales magnetic switch 4 and adsorbs the piece and close door fence 2 for door fence 2 atress magnetism is inhaled switch 4 and is inhaled the piece disconnection time with magnetism and trigger door fence alarm 7 and report to the police. The door sill alarm 7 adopts an audible and visual alarm and is used for prompting that the door sill is not closed through light and voice.
Photoelectric switches are oppositely arranged on two sides of the door sill 2 and connected with a pedestrian alarm 8 device for monitoring the alarm when a person enters or leaves the bus. Photoelectric switch includes photoelectric switch emission module 5 and photoelectric switch receiving module 6, and photoelectric switch emission module 5 installs on the rail 3 of door hurdle 2 one side, and photoelectric switch receiving module 6 relatively installs on the rail 3 of door hurdle 2 opposite side for triggering pedestrian alarm 8 when photoelectric signal is blocked and report to the police. The pedestrian alarm 8 adopts an audible and visual alarm for prompting that a person cannot drive by light and voice.
The working mode is as follows: the magnetic attraction switch 4 replaces a travel switch, and the door sill 2 is prevented from being opened due to vibration. If people get off the vehicle or the door bar 2 is opened due to other external force reasons, the magnetic absorption switch 4 acts to control the relay of the door bar 2 to be disconnected, and the door bar alarm 7 gives an alarm to remind people of closing the door bar 2.
