Abstract
The utility model relates to an approach-type self-discharging truck safety device which is used for a tipping skip type self-discharging truck. A positive electrode of a truck power supply E is connected with an audible and visual alarm through an induction type proximity switch CD, and the other end of the audible and visual alarm is connected with ground. Compared with the prior art, the utility model has the advantages of simple structure, easy maintenance, high operational reliability, long service life, etc. When the skip is lifted, a technique of automatic braking or extinguishing is used particularly, and the safe operation problem of a self-discharging truck is thoroughly solved.
Description
The utility model relates to a kind of proximity dumping truck safety device, specifically a kind of safety device of tipping bucket type dumping car.
That Chinese patent ZL92224925.3 discloses is a kind of " back-pressure buffer type automobile incline bucket safety alarm ", mainly mechanical stroke switch and the combined aural and visual alarm material on the automobile beam constitutes below the tipping bucket by being installed on, and power line voltage inputs to the sound and light alarm equipment through travel switch.When automobile was in non-discharging state, tipping bucket was pressed on the shock strut of travel switch, made the contact open in the travel switch, and no current passes through in this moment sound and light alarm equipment.When tipping bucket rose, shock strut moved under the contained spring effect, the closing of contact in the travel switch, and circuit turn-on, sound and light alarm equipment send sound and light signal and report to the police.The use of this device has warning function to the driver, can avoid because of the tipping bucket accident that object causes around the vehicle running collision that do not reset.Existing problem is: adopt the mechanical stroke switch to extract tipping bucket lifting signal, the top ripple vibration in the vehicle ' directly acts on the travel switch, usually causes the travel switch damage or causes misoperation.In addition, mechanical stroke construction of switch complexity, and must often safeguarding, otherwise can not goodly move malfunctioningly because of lubricating, even damage because of corrosion.
The purpose of this utility model provide a kind of simple in structure, be easy to safeguard, the proximity dumping truck safety device of functional reliability height, long service life, to reach the purpose of guaranteeing the dumping car safe operation.
The purpose of this utility model is achieved in that
A kind of proximity dumping truck safety device has combined aural and visual alarm, and the positive pole of automobile power source E is connected to combined aural and visual alarm through induction type near switch GD, the other end ground connection of combined aural and visual alarm.
The two ends of combined aural and visual alarm are parallel with a relay J, the open contact JK1 of relay and the two ends that are parallel to power supply E after the coil of electromagnetic valve F is connected, and electromagnetic valve F is installed in the pipeline of automobile air brake system.
The two ends of combined aural and visual alarm are parallel with a relay J, and one of the normally closed contact JK2 of relay is terminated at the positive pole of power supply E, and other end D inserts the working power positive input terminal of automotive ignition system.
Relay J is with the two ends that are parallel to combined aural and visual alarm after a normally closed push button switch AH connects.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the schematic circuit diagram of the utility model proximity dumping truck safety device.
Fig. 2 is the installation site structural representation of electromagnetic valve in the automobile air brake system among Fig. 1.
As shown in Figure 1, the positive pole of automobile power source E, enters 1 pin by its 2 pin and draws near switch GD through induction type, is connected to the combined aural and visual alarm that constitutes in parallel with indicator lamp RL by buzzer phone JB.3 pin, 4 pin near switch GD are its working power end, and 4 pin and power supply E positive pole join, 3 pin ground connection.Relay J and one is often closed the two ends that are parallel to combined aural and visual alarm after button switch AH connects.The open contact JK1 of relay and the two ends that are parallel to power supply E after the coil of electromagnetic valve F is connected.Electromagnetic valve F is that two position three-way valve is installed among the pipeline S of automobile air brake system, sees Fig. 2, and among the figure: DW is a spring brake, and JK is that motor-driven blow off valve, QK are the spring brake manually actuated control valve, and Q is a compressed air inlet port.
When dumping car was in non-discharging mode of operation, tipping bucket DX was in the effective range of induction type near switch GD, as Fig. 1.At this moment, be open circuited near the contact switch in the switch GD.When tipping bucket DX rises, when leaving the effective range near switch GD, GD in-to-in contact switch closure.Electric current is anodal through entering combined aural and visual alarm near switch GD by power supply E, and buzzer phone JB and indicator lamp RL send sound and light alarm simultaneously.While cutin relay J, make relay normally open contact JK1 adhesive, electromagnetic valve F is moved to position shown in Figure 2, the former pressurized air that is present in the spring brake DW is discharged by electromagnetic valve F through motor-driven blow off valve JF, brute spring in the drg DW with brake locking, makes vehicle be in braking mode by push rod.DX resets when tipping bucket, enter effective range near switch GD after, GD in-to-in contact switch is disconnected, buzzer phone JB, indicator lamp RL and the whole dead electricity of relay J, all clear.Relay normally open contact JK1 is released simultaneously, and electromagnetic valve F resets, and pressurized air enters spring brake DW from admission port Q through manually actuated control valve QK, electromagnetic valve F and motor-driven blow off valve JF, and brake is released.When tipping bucket DX is in the rise state, clean when needing short range to move the parking stall for goods in the tipping bucket is unloaded, press the button switch AH, can make relay coil J dead electricity, relay normally open contact JK1 disconnects, and electromagnetic valve F resets, and brake discharges.This moment, vehicle can move freely.Hand leaves button A, and relay J is switched at once, and vehicle enters braking mode again.
Vehicle for adopting the non-air brake system has a relay normally closed contact JK2 in addition in the utility model, one is terminated at the positive pole of power supply E, and other end D inserts the power supply positive input terminal of automotive ignition system, as the working power of ignition system.When tipping bucket DX was in the discharge position of rise, relay J was in conducting state, and contact JK2 is disconnected, and automobile can't start because of the ignition system dead electricity is flame-out.At this moment, press and often close button AH, make coil J dead electricity, contact JK2 closure can make automotive ignition system temporarily restore electricity, and can short range move the parking stall.After tipping bucket resetted, acoustooptic alarm system stopped, the relay J dead electricity, and contact JK2 closure, ignition system recovers normal working.
Compared with prior art, the utility model approach-type self-discharging truck safety device structure letter Single, be easy to safeguard, avoided available technology adopting mechanical stroke switch, because of the vehicle top Ripple vibration direct effect reaches the not good caused misoperation of maintenance thereon, action is malfunctioning, is To damaging functional reliability height, long service life. Particularly tipping bucket is in the rise state The time, the use of Braking mode or flame-out technology, the safety work that has thoroughly solved dump truck Problem.
