The utility model is characterized in that the dust cover of the gravity contact swing needle comprises a gravity contact swing needle, a gravity contact swing needle support shaft, a contact sheet steel, a dust cover and an insulating base; the gravity contact swing needle support shaft is arranged at the upper end of the dust cover; the gravity contact swing needle is sleeved on the gravity contact swing needle support shaft to swing side to side by taking gravity as power; both ends of the contact sheet steel are connected with the insulating base; the insulating base is fixed at both sides of the dust cover; the dust cover comprises a sealing ring for power cords; the warning device comprises a plurality of power cords, a switch, a loudspeaker (an indicator) and a plurality of batteries; one end of the power cord is connected with the contact sheet steel; the power cords, the switch and the loudspeaker (the indicator) are connected in series. The utility model overcomes the deficiencies of prior art and has the advantages of simple structure, easy processing, convenient use, reliability and security. The utility model is suitable for dump trucks.
Description
Technical field
The utility model relates to engineering dump truck safety lifting siren horn.
Background technology
The engineering dump truck load carrying ability is that the engineering dump truck wagon box progressively promotes during unloading about 10 to 45 tons, and the goods center of gravity is also along with higher.If engineering dump truck shakiness or Uneven road, the center of gravity of engineering dump truck changes, and causes the roll-over accident of engineering dump truck.Because busier during the engineering dump truck operation, Uneven road, chaufeur reason such as work long hours the chaufeur brain occurs and is in palsy or does not get off and observe vehicle and whether be in state of equilibrium, and roll-over accident frequently takes place under these circumstances.Particularly in recent years, the load carrying ability of engineering dump truck continued to increase and vehicle body lengthening, the observation difficulty of equilibrium problem whether when causing chaufeur to the engineering dump truck operation.At present, on market not about the device of engineering dump truck safety lifting.
Summary of the invention
The utility model overcomes deficiency of the prior art, provides a kind of simple in structure, is easy to processing and manufacturing, easy to use, reliable, safe engineering dump truck safety lifting siren horn.
Engineering dump truck safety lifting siren horn of the present utility model comprises that gravity touches to wave pin dust boot, alarm device and form.Described gravity touch wave the pin dust boot by gravity touch wave pin, gravity touch wave the needle rack axle, touch steel disc, dust boot, insulating base and door form.Described dust boot upper end is provided with gravity and touches and wave the needle rack axle, and gravity touches and waves the pin upper end and be enclosed within gravity and touch and wave the needle rack axle, is power with gravity, swing to the left and right; Touch steel disc and connected to form by two sheetmetals and single line, its two sheetmetals are fixed on the insulating base; Insulating base is fixed on the both sides of dust boot; Dust boot is provided with the power lead seal ring; Door is located at the dust boot front.
Described alarm device is made up of power lead, switch, loud speaker (indicator lamp), battery.One end of described power lead with touch steel disc and be connected; Power lead is connected with switch, loud speaker (indicator lamp).
Description of drawings
Fig. 1 the utility model structural representation
Fig. 2 the utility model circuit diagram
Among the figure: gravity touches and waves pin dust boot 1 gravity and touch and wave pin 2 and touch steel disc 3 insulating bases 4 gravity and touch and wave needle rack axle 5 power lead seal rings 6 and touch space 7
The specific embodiment
Gravity touches the upper end of waving pin dust boot 1 and is provided with gravity and touches and wave needle rack axle 5 among Fig. 1, gravity touches and waves needle rack axle 5 and gravity and touch and wave pin 2 and be connected, gravity touches and waves pin 2 length is 80mm, its other end is hung vertically in and touches the touching in the middle of the space 7 of steel disc 3, touching space 7 distances middle and that touch between the steel disc 3 is 4-8mm, touch steel disc 3 and connected to form by two sheetmetals and single line, its two sheetmetals are fixed on the insulating base 4.
Among Fig. 2 power lead by power lead seal ring 6, one ends with touch steel disc 3 and be connected, the power supply of power lead and 24V, switch, loud speaker are contacted, wherein switch, loud speaker are assemblied in the operator's compartment.Engineering dump truck electric current majority is a single wire system, and engineering dump truck itself is exactly a negative pole, negative pole occurs if any live wire and forges iron, and produces and refluxes.
Gravity touches and waves pin dust boot 1 and be assemblied in engineering dump truck crossbeam supporting traverse central horizontal position, in case vehicle body take place when crooked, gravity touch wave pin along with to touch steel disc 3 near or touch.The vehicle body skewness can not surpass 6 degree.The vehicle body skewness reaches 6 when spending in the engineering dump truck lifting process, and gravity touches and waves pin 2 and touch steel disc 3 and touch, and at this moment switches in the alarm device circuit, and loud speaker begins alarm.According to the alarm of loud speaker, chaufeur can be noted engineering dump truck safety lifting problem.
