Utility model content
What the utility model solved is the generation of at all stopping load truck overloading from hardware technology aspect from source.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
Flame-out protection device is forced in a kind of anti-truckload overload, it is characterized in that: comprise load measuring sensor, car speed sensor, voltage amplifier, op amp, with door, level shifting circuit, level driving circuit and relay K M, described load measuring sensor is arranged in lorry axle spring plate, for exporting the real-time load signal of lorry, described car speed sensor, be arranged in lorry axle spring plate, for exporting the vehicle speed signal of lorry, the mouth of described load measuring sensor is connected with the in-phase input end of op amp by voltage amplifier, the inverting input of described op amp is connected with benchmark load-carrying limit value, the mouth of described op amp is connected with an input end of door, the vehicle speed signal that described car speed sensor exports is connected with another input end of door through level shifting circuit, describedly to be connected with the coil of relay K M by level driving circuit with the mouth of door, the normally closed contact of described relay K M is connected on supplying on solenoid of lorry.
Flame-out protection device is forced in the anti-truckload overload of aforesaid one, it is characterized in that: between described voltage amplifier, op amp, be provided with switch S, described switch S is single pole double throw switch, and described switch S gets to the control position that A end is the overload of anti-truckload; Get to B end and detect the whether qualified of anti-truckload overload pressure flame-out protection device for traffic constable.
Flame-out protection device is forced in the anti-truckload overload of aforesaid one, it is characterized in that: described load measuring sensor is piezoelectric transducer.
The beneficial effects of the utility model are: flame-out protection device is forced in the anti-truckload overload that the utility model provides, can solar obligation on lorry, realize just accepting under the static state of lorry stagnation of movement the signal that load measuring sensor inputs, if lorry has overload, cut off immediately on diesel motor for solenoid fuel feeding, make it to start, cannot to set out on a journey transport, and be provided with the testing button of police's inspection, whether qualified to detect its performance, also can detect driver whether to have reequiped do trick simultaneously, can limit or stop the generation of load truck overloading, have a good application prospect.
Accompanying drawing explanation
Fig. 1 is the circuit controling drawing that flame-out protection device is forced in anti-truckload overload of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, flame-out protection device is forced in anti-truckload overload of the present utility model, can solar obligation on lorry, to limit or to stop the generation of load truck overloading, + UCC is the power supply forcing flame-out protection device, comprise load measuring sensor, voltage amplifier, op amp, with door, level shifting circuit, level driving circuit and relay K M, load measuring sensor is piezoelectric transducer, be arranged in lorry axle spring plate, for exporting the real-time load signal of lorry, vehicle speed signal, then export from the car speed sensor of lorry, the mouth of load measuring sensor is connected with the in-phase input end of op amp by voltage amplifier, the inverting input of op amp is connected with benchmark load-carrying limit value, the mouth of described op amp is connected with an input end of door, the vehicle speed signal that car speed sensor exports is connected with another input end of door through level shifting circuit, be connected with the coil of relay K M by level driving circuit with the mouth of door, the normally closed contact of described relay K M is connected on supplying on solenoid of lorry.
Flame-out protection device is forced in anti-truckload overload of the present utility model, and be provided with switch S between voltage amplifier, op amp, described switch S is single pole double throw switch, and described switch S gets to the control position that A end is the overload of anti-truckload; Get to B end and detect the whether qualified of anti-truckload overload pressure flame-out protection device for traffic constable; traffic constable gets to B end when pushing-off the wagons checks switch S; it is just qualified that running driving engine should stop working immediately; traffic at random sampling observation lorry of setting out on a journey with or without this device of dismounting, can have and privately dismantle then heavy punishment.
The principle of work of the pressure flame-out protection device for overloading wagon of the present utility model is as follows, 1) when lorry normally travels, car speed sensor inherently exports vehicle speed signal, must output low level by level shifting circuit, this low level has been blocked and has been made and door output low level with door, thus make level driving circuit be in off condition, relay K M coil blackout, normally closed contact closes, normal for solenoid fuel feeding on diesel motor, absolutely not allow when guaranteeing that lorry travels to carry out overweight flame-out control to ensure safety; 2) when the static loading of lorry zero speed of a motor vehicle, vehicle speed signal is zero, and level shifting circuit exports high level and delivers to and door.During the loading of lorry parking quiescence, piezoelectric transducer then exports truckload signal in real time, if load-carrying exceedes limit value, amplifier then exports high level and delivers to and door, all input high level and door just export high level with door two input ends, now illustrate that lorry is parking quiescence and goods overweight state, level driving circuit is in conducting state, relay K M obtains electric, and its normally closed contact disconnects, and diesel motor cuts off for solenoid fuel feeding, lorry can not start, need to be unloaded into below self nominal payload, just can start, transport.
In sum; the pressure flame-out protection device of what the utility model provided prevent overloading wagon; can solar obligation on lorry; realize just accepting under the static state of lorry stagnation of movement the signal that load measuring sensor inputs; if lorry has overload, cut off immediately on diesel motor for solenoid fuel feeding; make it to start; cannot to set out on a journey transport; and the police being provided with police's inspection detects testing button; trick repacking is done to prevent driver; can limit or stop the generation of load truck overloading, have a good application prospect.
More than show and describe groundwork of the present utility model, principal character and advantage.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
