Description

Technical Field

[0001] The utility model relates to the field of driving safety, in particular to an automatic ringing device in a driving area. Background Art

[0002] When the crane of the cold-rolled plate mill is lifting steel coils or overhauling in the single-frame area, due to the dense distribution of ground equipment and personnel, when the crane is operating in this area to lift steel coils or the crane is cooperating with the ground equipment for overhaul, according to safety standards, the crane driver should always manually ring the bell to alert the ground personnel in this area to pay attention, avoid ground personnel being directly under the objects being hoisted by the crane, and prevent the hoisted objects from falling and causing personal safety accidents.

[0003] When the crane in the cold-rolled plate mill is lifting steel coils or performing maintenance in the single-frame area, the crane driver is required to manually ring the bell all the time. However, the crane driver may occasionally forget to ring the bell manually due to distraction or unexpected situations during operation. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the driving operator may forget to ring the bell manually due to the driver's attention being distracted or unexpected situations occurring during operation.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is as follows: the utility model is an automatic ringing device in the driving area, including a driving vehicle, a proximity switch, a first detection sensing iron block and a second detection sensing iron block, the proximity switch is arranged on the driving vehicle, the first detection sensing iron block is arranged on the external structure and is located close to the side of the proximity switch, and the second detection sensing iron block is arranged on the external structure and is located on the side of the first detection sensing iron block.

[0006] Furthermore, the area between the first detection sensing iron block and the second detection sensing iron block is an automatic driving ringing area.

[0007] Furthermore, the proximity switch is electrically connected to an electric bell.

[0008] Preferably, the automatic alarm circuit for a vehicle entering or leaving an automatic ringing area is provided with an electric bell, a proximity switch, an electric bell ringing contactor, an intermediate relay for controlling a vehicle entering a specified area with automatic ringing, and an intermediate relay for controlling a vehicle leaving a specified area with automatic ringing.

[0009] The beneficial effects achieved by the utility model using the above structure are as follows:

[0010] 1. The manual bell function of driving has human control factors, and it is inevitable that the bell will not ring occasionally due to violations. The design and invention of the automatic alarm bell device can well solve the objective defects of manual bell ringing, that is, the driver occasionally fails to ring the bell according to safety regulations due to distraction or unexpected circumstances.

[0011] 2. The design and invention of the automatic alarm bell device is cost-effective, improves the intelligent level of driving, and solves the personal safety hazards in the process of safe production. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is the electrical schematic diagram of the automatic bell ringing device in the driving area proposed by the utility model. DETAILED DESCRIPTION

[0014] like Figure 1~Figure 2 As shown, the utility model is an automatic bell device for a driving area, comprising a driving vehicle, a proximity switch, a first detection sensing iron block and a second detection sensing iron block, the proximity switch being arranged on the driving vehicle, the first detection sensing iron block being arranged on an external structure and being located close to a side of the proximity switch, the second detection sensing iron block being arranged on an external structure and being located on a side of the first detection sensing iron block, the area between the first detection sensing iron block and the second detection sensing iron block being an automatic bell area for driving, and an electric bell being electrically connected to the proximity switch.

[0015] When the vehicle enters the boundary of the automatic alarm area of ​​the vehicle from the first detection sensing iron block or the second detection sensing iron block, the position detection proximity switch senses the position signal, and the automatic alarm device receives the position sensing signal and starts to automatically alarm and turn on the electric bell until the vehicle exits the boundary of the automatic ringing area of ​​the vehicle, then the position detection proximity switch senses the position signal, and the automatic alarm device receives the position sensing signal and automatically stops the alarm and turns off the electric bell.

[0016] Electrical working process: After the AC 220V power switch is closed, when the proximity switch SQ enters the automatic ringing area from the driving non-automatic ringing area, the first detection sensing iron block or the second detection sensing iron block senses the position signal, the K1 coil is energized and attracted, the KM1 coil is energized and remains attracted, the electric bell DL is energized and starts to alarm and ring, and at the same time, when the proximity switch SQ does not sense the position signal, the K1 coil is de-energized. When the driving vehicle exits from the automatic ringing area to the non-automatic ringing area, the proximity switch SQ senses the position signal again through the first detection sensing iron or the second detection sensing iron block, the K2 coil is energized, and then the KM1 contactor coil is de-energized, the electric bell DL is de-energized and stops the alarm, and then when the proximity switch SQ does not sense the position signal, the K2 coil is also de-energized. The automatic alarm ringing device repeats the above working process.

[0017] It should be understood that although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
