When, the hydraulic oil of the EF mouth output of turning gradient control valve 93 enters the automatically controlled P mouth for promoting operation valve group 97 by working oil path, automatically controlled
Promotion operation valve group 97 can control hydraulic oil and enter lift cylinder, and drive system is promoted and landing.
Carload freight self-unloading principle:
As shown in Fig. 1, Fig. 7, Fig. 8, under traffic condition, steel pipe 10 is lifted into three bracket systems of driven rear car,
Steel pipe is fixed using ratchet euphroe, since the first rear wheel assembly 28 and ground are there are gap 30mm, when vehicle to run, only
Two driving wheels of drawing head front truck and the second rear wheel assembly 29 roll, in order to the steering of vehicle.When the vehicle is run to tunnel,
It is changed to travel backward, steel pipe is pushed in tunnel.For tube group butt welding, pipe is broken at steel pipe butt welding in tunnel with sandbag
Pier 20 when steel pipe front end reaches and contacts pipe pier 20, releases the fixed rope of steel pipe, rises preceding liter first with preceding lifting cylinder 31
Bracket 32 is dropped to appropriate height, then manipulates translation oil cylinder 44 and shrinks inclined roller bracket 42, with supporting steel pipe；It at this time can be by preceding liter
It drops bracket system 3 to land, steel pipe keeps constant slope, and vehicle slowly exits, due to middle lifting roller support device 4 and rear lifting
Idler wheel is fitted on roller support device 5, steel pipe under the action of with pipe pier frictional force, by idler wheel roll slowly with rear car
It is detached from, recycles other end pipe pier by steel pipe support.And lifting roller support device 5 can adjust the liftoff of steel pipe 10 after manipulating
Highly, it is welded convenient for seamless interfacing group of the group to steel pipe 10；Vehicle smoothly unloads steel pipe and drops back from completion self-unloading process.
Bidirectional driving working principle:
For the manipulation of left-hand drive room 21 to move forward, the right manipulation of driver's cabin 22 is to travel backward.Bridge maneuvering system is main
Include:
1) diverter manipulates.Couple a course changing control reversal valve jointly at two diverter oil inlets, passes through rotation
Which diverter movement of manipulation may be selected in the valve handle.
2) electronic ignition switch, E-Gas, luminous lamp switch.Use for reference mature double control switch connection principle connection.
3) brake pedal.This vehicle braking system is gas cap oil type, and the gas that engine air compressor generates divides two-way respectively to enter
Major and minor driver's cabin brake pedal valve, by being respectively connected to the both ends of a gas circuit shuttle valve after brake pedal valve, the gas circuit shuttle valve control
Wet brake on drive axle processed, achievees the purpose that bi-directional braking.
4) shift control.The flexible axle of the shift control handle control of major and minor driver's cabin is connected in series, and co- controlling becomes
It shifts gears on fast case valve rod, two-way shift control is made to realize linkage.
The present invention has the advantages that
1) preceding lifting bracket device, rear lifting roller support device and rear lifting roller support device in this lifting system
It is all made of U-shaped hoisting frame, left and right stability is high；Flexible friction pad is arranged in preceding promotion frame, enhances hoisting frame carrying and stablizes
Property, improve the functional reliability of lifting device.
2) this hoisting way adds roller movement pattern using carrying roller, and movement is flat when can be realized oil transportation steel pipe self-unloading
