Example one
As shown in fig. 1, the embodiment of the utility model provides a big case lifting safety interlock, including limit switch 1, first sensor 2, signal converter 4, throttle position sensor control 6, limit switch 1 is connected with signal converter 4 electricity, and signal converter 4 is connected with first sensor 2 and throttle position sensor control 6 electricity respectively; the limit switch 1 controls the normal electrification of the signal converter 4, the signal converter 4 controls the first sensor 2 to start monitoring displacement signals and output voltage signals to the signal converter 4, and the voltage signals are amplified by the signal converter 4 and then transmitted to the throttle position sensor control 6, so that the rotating speed of an engine is controlled.
Furthermore, the device is also provided with an alarm device 5, the alarm device 5 is electrically connected with the limit switch 1, and the limit switch 1 controls the normal electrification of the alarm device 5. The alarm device 5 includes a flashing warning light or an audible and visual alarm as long as the driver can hear or see the alarm device to perform an alarm function. When the alarm device 5 is in the power-on state, a driver is reminded that the large box starts to lift.
Further, the device is also provided with a second sensor 3, the second sensor 3 is electrically connected with the limit switch 1, and the second sensor 3 is used for monitoring the lifting distance of the large box. When the lifting distance is more than 5mm, the limit switch 1 is turned on, the signal converter 4 and the alarm device 5 work normally, the alarm device 5 reminds a driver that the large box starts to lift, and the signal converter 4 controls the first sensor 2 to start monitoring displacement signals; when the lifting distance is less than 5mm, the limit switch 1 is turned off, and the signal converter 4 and the alarm device 5 cannot work.
Further, the first sensor 2 is located 5-10 mm away from the flange, and the first sensor 2 is used for monitoring the displacement of the flange; the accelerator position sensor control 6 is electrically connected with the engine, and the accelerator position sensor control 6 controls the rotating speed and running of the generator; the signal converter 4 is composed of two relays and a control circuit. After the signal converter 4 normally works, the first sensor 2 monitors the displacement signals and outputs 2-5V voltage to the signal converter 4, the 2-5V voltage is amplified by the signal converter 4 and then converted into 9-24V voltage, the amplified voltage is output to the throttle position sensor control 6, and then the throttle position sensor control 6 can control the rotating speed condition of the engine. When the displacement of the flange plate is larger than a preset value, the signal converter 4 outputs 9-24V voltage to the accelerator position sensor control 6, so that the rotating speed of the engine is controlled to be in an idling state, and the idling state can be 550-650 revolutions, so that the vehicle is prevented from normally running under the lifting state of a large box; when the displacement of ring flange is less than the default, first sensor 2 can not monitor the displacement signal of ring flange, and the engine is in normal condition to make the vehicle normally travel under big case lifting state.
Further, when the displacement of the flange plate is larger than a preset value, the signal converter 4 outputs 12V voltage to the accelerator position sensor control 6, and keeps the voltage for 3 seconds, so that the rotating speed of the engine is controlled to be in an idle speed state, wherein the idle speed state can be 550-650 revolutions, and normal running of the vehicle in a large box lifting state is prevented.

When no operation is performed on the self-reset button 7, the self-reset button 7 is in a closed state, and the signal converter 4 can output voltage to the accelerator position sensor control 6, so that the engine is controlled; when the self-reset button 7 is pressed, the self-reset button 7 is in an open state, and the signal converter 4 cannot output a voltage to the accelerator position sensor control 6, thereby releasing the control of the engine.
The utility model discloses a working process and theory of operation as follows:
when utilizing the utility model discloses a during safety interlock is lifted to big case, when big case lifting distance is greater than 5mm, limit switch 1 is opened, give signal converter 4 and 5 normal circular telegrams of alarm device, guarantee that it is in normal operating condition, at this moment, alarm device 5 reminds driver's big case to begin to lift, signal converter 4 control first sensor 2 begins to monitor the displacement volume of ring flange and to signal converter 4 output 2 ~ 5V's voltage, signal converter 4 transmits behind the voltage amplification for throttle position sensor control 6, when the displacement volume of ring flange is greater than the default, signal converter 4 exports 9 ~ 24V's voltage to throttle position sensor control 6, and then the rotational speed of throttle position sensor control 6 control engine, make the engine be in idle state, thereby make the vehicle can not normally travel under big case lifting condition. When the displacement of the flange plate is smaller than the preset value, the first sensor 2 cannot monitor the displacement signal of the flange plate, and the engine is in a normal state, so that the vehicle can normally run in a large box lifting state.
In the lifting process of the large box, when a vehicle needs to be moved to clear materials adhered in the large box, a driver can press the self-reset button 7, the self-reset button 7 releases the control on the accelerator position sensor control 6, so that the control on the engine is released, the alarm device 5 is still in a normal working state at the moment, and when the materials are cleared completely or the driver leaves the self-reset button 7, the self-reset button 7 automatically returns to the whole control system.
Example two
The utility model discloses still relate to a tipper, including embodiment one a big case lift safety interlock still includes big case, frame, transmission shaft, steering wheel and panel board.
