Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described:
As shown in Figure 1, a kind of dumping truck lifting interlock alarming device, comprise power supply 1, limit switch 2, alarm lamp 3, buzzer phone 4, speed switch 8, limit switch 2 is arranged at carriage of dump truck bucket and car body joint, limit switch 2 connects alarm lamp 4, limit switch 2 connects buzzer phone 4 by the advance gear node 6 of the gear universal seclector 5 of dumping truck and reversing gear node 7, and speed switch 8 is in parallel with gear universal seclector 5.
Most dumping truck is all that automatic catch is arranged, utilize gear universal seclector 5 to realize the switching of each gear, as long as possess the dumping truck of gear universal seclector 5, just can realize technical scheme of the present invention, when dumping truck lifting, carriage of dump truck bucket is separated with car body, limit switch 2 closes, alarm lamp 3 glimmers, prompting driver is now in dumping truck lifting state, once gear universal seclector 5 is pushed to advance gear or reversing gear by now driver's maloperation, advance gear node 6 on gear universal seclector 5 or reversing gear node 7 will be communicated with and conducting buzzer phone 4, buzzer phone 4 is sounded alarm, further prompting driver stops advance or the reversing operation of dumping truck, prevent and have an accident, when being in neutral, buzzer phone can not be switched on.
As preferred embodiment, limit switch 2 is gone back Negotiation speed switch 8 and is connected buzzer phone 4, and speed switch 8 is arranged on dumping truck tire measure speed gears.
A circuit controlled by speed switch 8 in parallel again between limit switch 2 with buzzer phone 4, speed switch 8 is arranged on the measure speed gears of dumping truck tire, measure speed gears is generally positioned on dumping truck the near front wheel, under the prerequisite that limit switch 2 is closed, when dumping truck transfixion, speed switch 8 disconnects, once slip car accident, speed switch 8 will close, conducting buzzer phone 4 is sounded alarm, driver can know and there occurs car accident of slipping within the shortest time, take brake measure in time, prevent in dumping truck lifting process and have an accident because slipping car.
As preferred embodiment, dumping truck lifting interlock alarming device also comprises circuit breaker 9 and malfunction monitoring loop, circuit breaker 9 is arranged between power supply 1 and limit switch 2, and malfunction monitoring loop comprises contactless switch 10 and indicator lamp 11, and the normally closed contact of contactless switch 10 connects indicator lamp 11.
When whole device normally runs, circuit breaker 9 conducting, warning normally works, the indicator lamp 11 that the normally closed contact of contactless switch 10 connects does not work, when device circuit occurs under-voltage, short circuit, during the problems such as overload, circuit breaker 9 disconnects, warning quits work, the conducting of contactless switch 10 normally closed contact, indicator lamp 11 is energized Chang Liang, remind driver's dumping truck lifting-warning device et out of order, the element of dumping truck lifting-warning device can be protected on the one hand, driver can Timeliness coverage fault overhaul on the other hand, avoid because of fault cause warning device cannot and the accident of alarm.
