Preferred again, sender unit is a photoemission cell 2; Signal receiving device is a photoelectric receiving tube, and promptly first signal receiving device is first photoelectric receiving tube 3, and the secondary signal receiving device is second photoelectric receiving tube 4; Warning device is a combined aural and visual alarm, and promptly first warning device is that first combined aural and visual alarm, 7, the second warning devices are rising tone light crossing-signal 8.
The driving warning that the utility model provides is in when work, when driving 1 handling object, switch 9 closures of weighing, photoemission cell 2 electroluminescence.When driving 1 moves to first photoelectric receiving tube, 3 places of Crane Rail 6; The 1 beginning arrival point dough figurine row of channels 5 of promptly driving a vehicle; After first photoelectric receiving tube 3 receives the optical signal that is sent by photoemission cell 2 optical signal is converted into electric signal; And the electric signal after will transforming outputs in first combined aural and visual alarm 7 that is installed in entrance, 5 two ends, walkway, ground, the rising tone light crossing-signal 8 and gives the alarm through Programmable Logic Controller 10; Remind the ground staff to drive a vehicle 1 with this, notice that the high-altitude object falls soon through walkway, ground 5.When driving 1 when moving to second photoelectric receiving tube, 4 places of Crane Rail 6, second photoelectric receiving tube 4 receives from the optical signal of photoemission cell 2 outputs, converts the optical signal that receives into electric signal and mouth in Programmable Logic Controller 10.10 pairs of electric signal that receive of Programmable Logic Controller carry out analyzing and processing and stop to first combined aural and visual alarm 7, rising tone light crossing-signal 8 output signals; Make first combined aural and visual alarm 7, rising tone light crossing-signal 8 stop to report to the police; Remind the ground staff to drive a vehicle 1 with this, can pass through walkway, ground 5 safely through walkway 5.
Perhaps when driving 1 moves to second photoelectric receiving tube, 4 places of Crane Rail 6; The 1 beginning arrival point dough figurine row of channels 5 of promptly driving a vehicle; After second photoelectric receiving tube 4 receives the optical signal that is sent by photoemission cell 2 optical signal is converted into electric signal; And the electric signal after will transforming outputs in first combined aural and visual alarm 7 that is installed in entrance, 5 two ends, walkway, ground, the rising tone light crossing-signal 8 and gives the alarm through Programmable Logic Controller 10; Remind the ground staff to drive a vehicle 1 with this, notice that the high-altitude object falls soon through walkway, ground 5.When driving 1 when moving to first photoelectric receiving tube, 3 places of Crane Rail 6, the optical signal that first photoelectric receiving tube 3 receives, convert the optical signal that receives into electric signal and mouth in Programmable Logic Controller 10 from photoemission cell 2 outputs.10 pairs of electric signal that receive of Programmable Logic Controller carry out analyzing and processing and stop to first combined aural and visual alarm 7, rising tone light crossing-signal 8 output signals; Make first combined aural and visual alarm 7, rising tone light crossing-signal 8 stop to report to the police; Remind the ground staff to drive a vehicle 1 with this, can pass through walkway, ground 5 safely through walkway 5.
After driving 1 handling object passes through first photoelectric receiving tube 3 of Crane Rail 6; But when before second photoelectric receiving tube, 4 places of no show Crane Rail 6 still, turning back to this process of first photoelectric receiving tube, 3 places again and occurring; Photoemission cell 2 continues luminous; First photoelectric receiving tube 3 continues to receive the optical signal that sent by photoemission cell 2 and optical signal is converted into electric signal, and the electric signal after will transforming again continues to output in the Programmable Logic Controller 10.10 pairs of electric signal that receive of Programmable Logic Controller carry out analyzing and processing, and continue treated electric signal is outputed in first combined aural and visual alarm 7, the rising tone light crossing-signal 8.First combined aural and visual alarm 7, the rising tone light crossing-signal 8 that are installed in entrance, 5 two ends, walkway, ground receive electric signal and continue and give the alarm, and remind the ground staff to drive a vehicle 1 fully through walkway, ground 5 with this, notice that the high-altitude object falls.
Perhaps after driving 1 handling object passes through second photoelectric receiving tube 4 of Crane Rail 6; But when before first photoelectric receiving tube, 3 places of no show Crane Rail 6 still, turning back to this process of second photoelectric receiving tube, 4 places again and occurring; Photoemission cell 2 continues luminous; Second photoelectric receiving tube 4 continues to receive the optical signal that sent by photoemission cell 2 and optical signal is converted into electric signal, and the electric signal after will transforming again continues to output in the Programmable Logic Controller 10.10 pairs of Programmable Logic Controllers receive to such an extent that electric signal carries out analyzing and processing, and continue treated electric signal is outputed in first combined aural and visual alarm 7, the rising tone light crossing-signal 8.First combined aural and visual alarm 7, the rising tone light crossing-signal 8 that are installed in entrance, 5 two ends, walkway, ground receive electric signal and continue and give the alarm, and remind the ground staff to drive a vehicle 1 fully through walkway, ground 5 with this, notice that the high-altitude object falls.
When driving 1 not during the handling object, the switch 9 of weighing in the instrument case of load limiter breaks off, and makes photoemission cell 2 can not get electroluminescence.Even when driving 1 moves to first photoelectric receiving tube, 3 places or second photoelectric receiving tube, 4 places of Crane Rail 6; First photoelectric receiving tube 3 and second photoelectric receiving tube 4 can not receive optical signal; So no electric signal outputs to Programmable Logic Controller 10; Also no signal outputs in first combined aural and visual alarm 7, the rising tone light crossing-signal 8, thereby guarantees when driving a vehicle 1 not during the handling object, and first combined aural and visual alarm 7, rising tone light crossing-signal 8 do not give the alarm all the time.
The utility model adopts the state of the handling object of will driving a vehicle, and is delivered on the acoustic-optic alarm of ground, and tip ground personnel dodge.As yet not during the handling object, even warning is not sent in the driving walking yet, the safety to the ground staff in the time of reflecting the driving operation so truly has or not influence in driving.The utility model is rational in infrastructure, and effect is remarkable, and is practical.
It should be noted last that; The above specific embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to instance the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
