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.
Of the invention is a little:
1) vehicle scheme is using double articulated frame structures, in order to relatively swing；Then joined by pivoting support
It connects and improves the performance that vehicle adapts to complicated road in order to relative rotation.
2) bidirectional driving function；And left and right driver's cabin is located at the same end of vehicle frame, convenient for handling pipeline and stringing, driver
It is high to drive vehicle comfort.
3) driven rear car is segmented, is divided into two sections.After dismantling, Rear frame leading portion and drawing head front truck constitute four-wheel car
Structure, in order to which headstock has enough to meet the need place；In addition, the first rear wheel assembly 28 and ground is there are gap 30mm, when vehicle to run, only
Tire on the driving wheel assembly 27 of drawing head front truck and the second rear wheel assembly 29 rolls, in order to the steering of vehicle.
4) requirement transported according to large diameter steel pipe using low platform body frame structure for automotive, arc clamping device, and utilizes ratchet
Euphroe fixes steel pipe, the safety of transport, high stability.
5) self-unloading steel pipe function.By manipulating preceding lifting bracket device 3, middle lifting roller support device 4, going up and down idler wheel afterwards
Bracket system 5 is realized, and the surfaces such as idler wheel contacted with steel pipe, has laid protective polyurethane layer, and guarantee is transported steel pipe table
Face is not scraped off, and ensure that steel pipe anticorrosive layer quality.
6) vehicle good appearance, it is easy to operate；Vehicle body is relatively narrow, and occupancy lane space is few, convenient for fortune pipe and stringing.
Although the embodiments of the invention are described in conjunction with the attached drawings, but patent owner can be in appended claims
Within the scope of make various deformations or amendments, as long as it does not exceed the scope of protection described in the claims to the invention, all should
Within protection scope of the present invention.
