Abstract
A kind of lift bridge reversing lifting device, including: it is connected to cab lift bridge switch and the lift bridge electromagnetic valve of automobile key power supply, described lifting air bag is connected to gas receiver by lift bridge electromagnetic valve, the control end of lifter electromagnetic valve promotes relay by reversing and is connected to cab lift bridge switch, and reversing promotes the control end of relay and is connected to back-up lamp holding wire.When normally moving forward, astern signal line promotes relay do not work without electricity, reversing, is normally closed relay owing to reversing promotes relay, does not affect the break-make of circuit, and lift bridge electromagnetic valve normally works, and vehicle bridge can normal hoisting or carrying.When reversing, astern signal line is energized, and reversing promotes the magnet exciting coil energising of relay, and the normally-closed contact of outfan disconnects, and now lift bridge electromagnetic valve power-off, the most no matter whether this front axle or not loaded state, and vehicle bridge is all by lifting.Tire does not contacts with ground.So, would not occur misrouting the situation to occurring tire to eat tire.
Description
Technical field
The present invention relates to a kind of lift bridge reversing lifting device.
Background technology
At present, increasing truck is with lift bridge.It has good relative to the advantage of common vehicle bridge
Economy, during heavy duty, vehicle bridge can lower load capacity, vehicle bridge is mentioned during unloaded or underloading, make wheel and ground without
Frictional resistance, reduces oil consumption, reduces tire wear simultaneously.But it is servo-actuated that lift bridge has a drawback to be that this bridge is usually, in reversing
During, if vehicle bridge is the state of carrying, the tire on this bridge be easy to misroute to, make tire wear aggravate.At present
For solving this problem on market, typically install backing locking mechanism additional, make lift bridge wheel not occur to turn in the case of reversing
Dynamic.Install this mechanism additional, relatively costly.
Summary of the invention
The present invention is in order to overcome the deficiency of above technology, it is provided that a kind of low cost when truck is moveed backward by vehicle bridge
Mention, make tire not contact with ground, prevent to misroute to lift bridge reversing lifting device.
The present invention overcomes its technical problem be the technical scheme is that
A kind of lift bridge reversing lifting device, including: it is connected to cab lift bridge switch and the lifting of automobile key power supply
Bridge electromagnetic valve, described lifting air bag is connected to gas receiver by lift bridge electromagnetic valve, and the control end of described lifter electromagnetic valve leads to
Crossing reversing lifting relay and be connected to cab lift bridge switch, described reversing promotes the control end of relay and is connected to back-up lamp
Holding wire.
The invention has the beneficial effects as follows: when normally moving forward, astern signal line promotes relay not work without electricity, reversing
Making, be normally closed relay owing to reversing promotes relay, do not affect the break-make of circuit, lift bridge electromagnetic valve normally works, vehicle bridge
Can normal hoisting or carrying.When reversing, astern signal line is energized, and reversing promotes the magnet exciting coil energising of relay, outfan
Normally-closed contact disconnect, now lift bridge electromagnetic valve power-off, the most no matter whether this front axle or not loaded state, and vehicle bridge all will carry
Rise.Tire does not contacts with ground.So, would not occur misrouting the situation to occurring tire to eat tire.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
In figure, 1. the reversing of automobile key power supply 2. cab lift bridge switch 3. promotes relay 4. back-up lamp holding wire 5.
Lift bridge electromagnetic valve.
Detailed description of the invention
1 the present invention will be further described below in conjunction with the accompanying drawings.
A kind of lift bridge reversing lifting device, including: be connected to the cab lift bridge switch 2 of automobile key power supply 1 with
And lift bridge electromagnetic valve 5, promoting air bag and be connected to gas receiver by lift bridge electromagnetic valve 5, the control end of lifter electromagnetic valve 5 leads to
Crossing reversing lifting relay 3 and be connected to cab lift bridge switch 2, reversing promotes the control end of relay 3 and is connected to back-up lamp
Holding wire 4.When normally moving forward, astern signal line 4 promotes relay 3 do not work without electricity, reversing, owing to reversing lifting continues
Electrical equipment 3 is normally closed relay, does not affect the break-make of circuit, and lift bridge electromagnetic valve 5 normally works, and vehicle bridge can normal hoisting or hold
Carry.When reversing, astern signal line 4 is energized, and reversing promotes the magnet exciting coil energising of relay 3, and the normally-closed contact of outfan breaks
Opening, now lift bridge electromagnetic valve 5 power-off, the most no matter whether this front axle or not loaded state, and vehicle bridge is all by lifting.Tire and ground
Face does not contacts.So, would not occur misrouting the situation to occurring tire to eat tire.
