In conjunction with reference to figure 1, Fig. 2 and Fig. 8, show the preferred implementation of suspension bracket driver train 4 in the present embodiment, suspension bracket driver train 4 comprises motor 41, the chain wheel driving mechanism being driven by motor 41 and push rod 45.
Particularly, motor 41 is arranged on vehicle frame 1.Chain wheel driving mechanism comprises drive sprocket 42, driven sprocket 43 and driving chain 44.Drive sprocket 42 drives and is connected with motor 41.Driven sprocket 43 is arranged on vehicle frame 1.Driving chain 44 windings are on drive sprocket 42 and driven sprocket 43, and driving chain 44 can be full chain structure, also can adopt the unitized construction of chain and rod member, as long as guarantee that the part being set on drive sprocket 42 and driven sprocket 43 is always chain.The line of centres with drive sprocket 42 and driven sprocket 43 is divided driving chain 44, and driving chain 44 comprises the first chain segment 441 and the second chain segment 442 that is positioned at drive sprocket 42 both sides.Push rod 45 is connected with travelling cradle with driving chain 44 respectively, like this, when the mobile travelling cradle of needs, as long as open motor 41, can drive travelling cradle to move by chain 44, push rod 45, and the distance between suspension bracket 2 and suspension bracket 3 is changed.When the distance between suspension bracket 2 and suspension bracket 3 meets requiring of need lifting freight container, brake motor.
By above learning, in the present embodiment, suspension bracket 2 and suspension bracket 3 are travelling cradle, and wherein suspension bracket 2 is the first travelling cradle, and suspension bracket 3 is the second travelling cradle.For making suspension bracket 2 and suspension bracket 3 drive motion simultaneously by same suspension bracket driver train 4, to simplify the operation and to improve regulated efficiency, preferably, push rod 45 comprises the first push rod 451 and the second push rod 452, the first push rod 451 is connected with the first chain segment 441 with the first travelling cradle 2 respectively, the second push rod 452 is connected with the second chain segment 442 with the second travelling cradle 3 respectively, can realize at an easy rate in the transmission process of driving chain 44, control suspension bracket 2 and synchronously do move toward one another or do the movement deviating from mutually with suspension bracket 3.
Preferably, for realizing suspension bracket 2 and suspension bracket 3 automatically stopping in moving process, and the lifting space of stop position correspondence freight container to be lifted, this Self-loading-unloading transport trolley also comprises approach switch (not shown) and controller.Wherein approach switch is arranged on vehicle frame 1, being used for can be the first push rod 451 at push rod 45(, also can be the second push rod 452) send braking information to controller during apart from approach switch predeterminable range (this predeterminable range is for example 0), controller, for controlling motor 41 splines according to braking information, makes suspension bracket automatically stop moving and locating.Easily understand, for realizing the lifting of multiple different size freight container, approach switch can be for a plurality of, a plurality of stop positions of corresponding suspension bracket.
In addition, in a kind of unshowned embodiment, suspension bracket driver train 4 can be the first hydraulic actuating cylinder, the suspension bracket 3 of still take is example as travelling cradle, the first end of the first hydraulic actuating cylinder is connected with vehicle frame 1, and the second end is connected with suspension bracket 3, by controlling the flexible of the first hydraulic cylinder piston rod, realize the movement of suspension bracket 3, change the distance between suspension bracket 2 and suspension bracket 3.Certainly, when suspension bracket 2 is also travel(l)ing rest, suspension bracket 2 also can be promoted by hydraulic ram.
Referring to Fig. 6 and Fig. 7, preferably, on suspension bracket 3, be also provided with positioning plate 6 and rotary-locking device 7, positioning plate 6 at suspension bracket toward on vehicle frame during Stuff (to) 9, spacing to freight container 9, freight container 9 is successfully in place.Rotary-locking device 7 is for coordinating with the corner fittings hole of freight container 9 bottoms, two ends, realize the location of freight container 9, by rotary-locking device 7 is arranged on travelling cradle and is moved with travelling cradle, the relative position relation of travelling cradle and rotary-locking device 7 is determined, reduced location to the case time, and when realizing a tractor serves several purposes, can reduce on vehicle frame 1 and to revolve lock quantity as location.
Preferably, rotary-locking device 7 comprises lock housing 71, lock core 72, pipe link 73 and revolves lock oil cylinder 74.Wherein lock housing 71 is for example installed on travelling cradle 3 by the mode of welding, and has circular mounting hole.Lock core 72 is set in circular mounting hole, can rotate around self axis.The first end of pipe link 73 and lock core 72 are hinged.Revolve lock oil cylinder 74 be arranged on travelling cradle, and revolve lock the piston rod of oil cylinder 74 and the second end of pipe link 73 hinged.Like this, control and to revolve the flexible of lock oil cylinder 74 piston rods, can rotate by pipe link 73 pushing lock cylinders 72, realize the stretching out or bounce back of lock core 72 of rotary-locking device 7, realize the auto lock of freight container is located.
It should be noted that, in the present embodiment, although take suspension bracket 3, have been described in detail as example, easily understand, the structure suspension bracket 2 that suspension bracket 3 adopts also can adopt equally, such as also the structures such as positioning plate, rotary-locking device can be set on suspension bracket 2.
In sum, Self-loading-unloading transport trolley tool provided by the invention has the following advantages:
1) integrate freight container lifting, loading, unloading, transport, make the Self-loading-unloading of freight container faster, convenient;
2) both can load and unload, transport 40 forty equivalent unit 40s, also can, for handling, the transportation of other set of specifications vannings such as 20 feet of grades, realize a tractor serves several purposes;
3) rotary-locking device is arranged on travelling cradle, and the relative position relation of travelling cradle and rotary-locking device is determined, has reduced location to the case time, can reduce as location, to revolve lock quantity on vehicle frame when realizing a tractor serves several purposes; Can realize automatic rotary lock, make whole operating process faster, save time.
