Abstract
The utility model relates to an unloading alarm of a tipper, which is composed of a power supply, a self-locking switch, a normally closed proximity switch, a DC relay of 24 V, a speech alarm device, a flash alarm device and a change-over switch, wherein, the power supply adopts a vehicle-carrying power supply; the normally closed proximity switch has a positive and a negative conductors; the two conductors come out from a power supply lead and are provided with the self-locking switch; the self-locking switch is connected with the normally closed proximity switch and the DC relay of 24 V in series; the normally closed proximity switch is arranged on the upper surface of a tipper chassis at the back of an operator cabin; a good bucket under a reset state can make the normally closed proximity switch under an off state; when the good bucket is raised, the normally closed proximity switch under a normally closed state; the normally closed proximity switch is connected with the DC relay of 24 V in series; normally open contacts of the DC relay of 24 V are connected with the speech alarm device and the flash alarm device in series; the speech alarm device and the flash alarm device are connected with the change-over switch which carries out selected control; then, the change-over switches on the normally open contacts of the DC relay, and the unloading alarm of a tipper is formed. The utility model can be used as an assistant of safe driving for an operator of the tipper.
Description
Technical field: the utility model relates to warning device, relates in particular to dumping car unloading annunciator.
Background technology: dumping car lifts the unloading of goods bucket, mainly implements unloading operation by the operating experience of chaufeur, because navigating mate often is eager to make up for lost time, forgets sometimes after the unloading goods bucket is put down, and promptly drives to travel, and therefore causes the accident.
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of dumping car unloading annunciator is provided, when the goods bucket lifted the enforcement unloading, audio alert was implemented in the automatic conducting of alarm circuit, enquiry bucket does not put down comes the position that resets fully, and audio alert does not just stop.This just can remind chaufeur to carry out proper handling effectively, and the goods bucket after the unloading is resetted, and guarantees safety.
Summary of the invention: dumping car unloading annunciator described in the utility model, include power supply, self-lock switch, closed type near switch, 24V DC relay, phonetic alarm device, flashing alarm device, change-over swith and relay normally open contact composition, said power supply adopts the vehicle power of dumping car, said closed type is a 24V direct current photoelectric switch near switch, and positive and negative two leads are arranged.Come out by power supply lead wire, be provided with self-lock switch, its role is in the automotive servicing process, wagon box lifts, can be with the way cut off of closing self-lock switch, and self-lock switch series connection closed type is near switch and 24V DC relay.Said closed type is near switch, be arranged at above the chassis of dumping car operator's compartment back, the goods bucket of dumping car should be near closed type near switch under reset mode, make closed type be in off-state near switch, in case dumping car goods bucket lifts, said closed type switch then is in normally off, the circuit of conducting dumping car unloading described in the utility model annunciator.Closed type is near switch serial connection 24V DC relay, the open contact of 24V DC relay, series connection is connected to phonetic alarm device and flashing alarm device, said flashing alarm device can be arranged on the position of being convenient to driver's observation in the operator's compartment, said phonetic alarm device divides makes two parts, the less loud speaker of one volume can be set in operator's compartment, a loud speaker that volume is bigger is set outside car, so that reliable the warning, and personnel to avoid personal injury beyond this point around informing car body.Phonetic alarm device and flashing alarm device are connected to change-over swith, and audio alert and flashing light alarm are selected control, can audio alert, also can flashing light alarm, and also can report to the police simultaneously.Said change-over swith is connected with the open contact of 24V DC relay again, promptly forms dumping car unloading annunciator described in the utility model.
Dumping car unloading annunciator described in the utility model, when dumping car goods bucket lifts the enforcement unloading, closed type is near switch turning circuit automatically, carry out the warning of voice and flash of light dual mode simultaneously, be unlikely to take place again the phenomenon that the goods bucket does not reset and runs with regard to driving, become the assistant that the dumping car driver safety is driven, the accident that can avoid dumping car goods bucket to hang bad road sign and so on preferably.
Description of drawings: accompanying drawing is the structural representation of dumping car unloading annunciator described in the utility model.1-power supply, 2-self-lock switch, 3-closed type is near the open contact of switch 4-24V DC relay 5-phonetic alarm device 6-flashing alarm device 7-change-over swith 8-24V DC relay
The specific embodiment: referring now to accompanying drawing, be described as follows in conjunction with the embodiments: dumping car unloading annunciator described in the utility model, including power supply 1, self-lock switch 2, closed type forms near the open contact 8 of switch 3,24V DC relay 4, phonetic alarm device 5, flashing alarm device 6, change-over swith 7 and 24V DC relay, said power supply 1 adopts the vehicle power of dumping car, said closed type is a 24V direct current photoelectric switch near switch 3, and positive and negative two leads are arranged.Come out by power supply 1 lead-in wire, be provided with self-lock switch 2, its role is in the automotive servicing process, wagon box lifts, can be with the way cut off of closing self-lock switch 2, and self-lock switch 2 series connection closed types are near switch 3 and 24V DC relay 4.Said closed type is near switch 3, be arranged at above the chassis of dumping car operator's compartment back, the goods bucket of dumping car should be near closed type near switch 3 under reset mode, make closed type be in off-state near switch 3, in case dumping car goods bucket lifts, 3 on said closed type switch is in normally off, the circuit of conducting dumping car unloading described in the utility model annunciator.Closed type is near switch 3 serial connection 24V DC relay 4, the open contact 8 of 24V DC relay, series connection is connected to phonetic alarm device 5 and flashing alarm device 6, said flashing alarm device 6 can be arranged on the position of being convenient to driver's observation in the operator's compartment, said phonetic alarm device was made two parts in 5 minutes, the less loud speaker of one volume can be set in operator's compartment, a loud speaker that volume is bigger is set outside car, so that reliable the warning, and personnel to avoid personal injury beyond this point around informing car body.Phonetic alarm device 5 and flashing alarm device 6 are connected to change-over swith 7, and audio alert and flashing light alarm are selected control, can audio alert, also can flashing light alarm, and also can report to the police simultaneously.Said change-over swith 7 is connected with the open contact 8 of 24V DC relay again, promptly forms dumping car unloading annunciator described in the utility model.Dumping car unloading annunciator described in the utility model, when dumping car goods bucket lifts the enforcement unloading, closed type is near switch 3 turning circuit automatically, carry out the warning of voice and flash of light dual mode simultaneously, be unlikely to take place again the phenomenon that the goods bucket does not reset and runs with regard to driving, become the assistant that the dumping car driver safety is driven, the accident that can avoid dumping car goods bucket to hang bad road sign and so on preferably.
