Abstract
The utility model relates to a vehicle contactless type lifting warning device used for special automobiles equipped with a lifting device, such as a self-discharging vehicle, and for preventing the lifting device from being in a hoisting state during the driving process. The utility model comprises a proximity switch (1), a relay contactor (2), a sounding device (4) and a light emitting device (5), etc., wherein, the proximity switch (1) is communicated with the relay contactor (2), the relay contactor (2) is communicated with the sounding device (4) and the light emitting device (5), and the proximity switch (1) adopts an inductance type proximity switch. The proximity switch (1) transmits detected signals to the relay contactor (2), and the relay contactor (2) isolates and amplifies the signals, and drives the sounding device (4) and the light emitting device (5) to alarm, so as to remind the drivers. The utility model has the advantages that the utility model is not required to be contacted with real objects, has no abrasion, and can send out alarm signals through electric induction; the structure is simple, the wiring is convenient, the cost is low, the warning is reliable, and the effect is good.
Description
Technical field
That the utility model relates to is that special-use vehicle that a kind of dumping car etc. is equipped with jacking system uses, prevent that in its driving process jacking system still is in the automobile-used contactless lifting warning device of lifting state.
Background technology
Dumping cars etc. are equipped with the special-use vehicle of jacking system, and are abnormally dangerous if it is in the lifting state in the process of moving, are easy to cause major accident.For preventing accident, in time remind the driver, all need to install additional the lifting warning device, avoid special-use vehicle when being in the lifting state, to travel.The general employing of existing lifting warning device presses down mechanical contact formula lifting warning device, it be with contact switch as incoming signal, also have employing in oil circuit the setting pressure switch as incoming signal; Add compositions such as voltage transformer, amplifier, sound-producing device.Its shortcoming is: when overweight or shock absorption device was impaired when piece under pressure carrying, contact switch was fragile, causes warning device to lose efficacy complex structure, cost height; Then wiring complexity of pressure switch, the cost height is installed inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile-used contactless lifting warning device for special-use vehicle that dumping car etc. is equipped with jacking system, and it is in kind that it need not contact, passes through electric induction, can give the alarm, and simple in structure, easy-to-connect, cost is low, and it is reliable, effective to report to the police.
The object of the present invention is achieved like this, and it includes near compositions such as switch, relay-contactless switch, sound-producing device, light-emitting devices.Be communicated with relay-contactless switch near switch, relay-contactless switch is communicated with sound-producing device, light-emitting device, is near switch, relay-contactless switch, sound-producing device, light-emitting device power supply by automobile power source.
Near switch is inductance approach switch, can be normally closed positive-negative-positive inductance approach switch, also can be often to open the NPN inductance approach switch.
Inductance approach switch belongs to a kind of position transduser that switching value output is arranged, it is made up of LC high frequency oscillator and amplification treatment circuit, utilize metal object when the vibration inductive head that can generate an electromagnetic field near this, make interior of articles produce eddy current, this eddy current reacts near switch, makes near the decay of switch vibration ability, and internal current changes, identify thus and have or not metal object approaching, and then the on-off of master cock.Because the lifting device of special-use vehicle is metal object, whether the lifting device of special-use vehicle is in the lifting state, just can detect by this type of inductance approach switch.Near switch detected signal is passed to relay-contactless switch, relay-contactless switch is isolated, amplifying signal, and drives sound-producing device and light-emitting device, is reported to the police the prompting chaufeur by sound-producing device and light-emitting device.
When being non-metallic objectsit is not a metal object, only needing to change condenser near switch into by inductance type and get final product as object to be detected.
Because the utility model has adopted near switch, it is in kind that the lifting warning device need not contact, therefore, the utlity model has it and need not the contact material object, do not have wearing and tearing, by electric induction, can give the alarm; And simple in structure, easy-to-connect, characteristics such as cost is low, and it is reliable to report to the police, effective.
Four, description of drawings
Fig. 1 is the utility model (is normally closed positive-negative-positive inductance approach switch near switch) circuit diagram;
Fig. 2 is near switch being the circuit diagram when often opening the NPN inductance approach switch.
Five, the specific embodiment
Fig. 1, Fig. 2 are two embodiment of the present utility model, and it includes near compositions such as switch 1, relay-contactless switch 2, sound-producing device 4, light-emitting devices 5.Be communicated with relay-contactless switch 2 near switch 1, relay-contactless switch 2 is communicated with sound-producing device 4, light-emitting device 5, is near switch 1, relay-contactless switch 2, sound-producing device 4, light-emitting device 5 power supplies by automobile power source 3.
Near switch 1 is inductance approach switch, can be normally closed positive-negative-positive inductance approach switch (as shown in Figure 1), and this embodiment's is that normally closed positive-negative-positive TK22P35D is near switch near switch 1.
Near switch 1 also can be often to open NPN type inductance approach switch (as shown in Figure 2), this embodiment near switch 1 for often opening NPN type TK22NC35D near switch.
Near switch 1 detected signal is passed to relay-contactless switch 2, relay-contactless switch 2 is isolated, amplifying signal, and drives sound-producing device 4 and light-emitting device 5, is reported to the police by sound-producing device 4 and light-emitting device 5.
When being non-metallic objectsit is not a metal object, only needing to change condenser near switch 1 into by inductance type and get final product as object to be detected.
Therefore, the utlity model has it and need not the contact material object, there are not wearing and tearing, by electric induction, namely Can give the alarm; And simple in structure, easy-to-connect, the characteristics such as cost is low, and it is reliable to report to the police, effective.
