Detailed description of the invention
In order to further illustrate principle of the present utility model and structure, in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
This utility model, when describing orientation, is front with orientation, dumper headstock place, after orientation, tailstock place is.
Self-discharging semitrailer of the present utility model includes vehicle frame, the walking mechanism being arranged at vehicle frame lower rear and is arranged at the compartment above vehicle frame, is provided with elevating ram between front end, compartment and vehicle frame front end.
Refering to Fig. 2 to Fig. 8, this self-discharging semitrailer vehicle frame includes: main body of vehicle frame 21, is arranged on the towing plate 23 of main body of vehicle frame 21 front bottom surface and is arranged on the towing pin 24 on this towing plate 23.
Main body of vehicle frame 21 includes: two longerons and be connected to the crossbeam between two longerons.
The position of the close front end that towing plate 23 is connected between two longerons, towing pin 24 is fixed on towing plate 23 and extends downwardly from towing plate 23.When semitrailer docks with tractor, tractor saddle is positioned at below towing plate 23 and slides into along towing plate 23 and mounts with towing pin 24.
Position after the corresponding towing pin 24 of main body of vehicle frame 21 is provided with supporting leg 26, and when semitrailer separates with tractor, supporting leg 26 supports vehicle frame together with the walking mechanism 3 at vehicle frame 2 rear.
Position before the corresponding towing pin 24 of main body of vehicle frame 21 is additionally provided with support means 25, and this support means 25 can be supported in ground, it is also possible to packs up and is positioned on towing plate 23.
Support means 25 can switch on duty or off working state by lifting, upset or expanding-contracting action, during duty, support means 25 can be supported in ground, thus when semitrailer separates with tractor and during elevating ram (when getting rid of extension lifting operation), trailer front portion can be using support means 25 as support, the opposing oil cylinder support reaction to vehicle frame front portion, it is ensured that the security and stability after lifting, prevents trailer front portion stress from damaging；During off working state, support means 25 can be retracted to its bottom surface be not less than the bottom surface of towing plate 23 by lifting, upset or expanding-contracting action, it is ensured that tractor and semitrailer normally mount, and do not affect normal transport operation.
The concrete structure of support means 25 is varied, enumerates the structure of several preferred embodiment below with reference to accompanying drawing.
Support means first embodiment.
Refering to Fig. 2 to Fig. 6, the support means 25 of the present embodiment includes: two support seat 251 and two support bars 252, two bottom surfaces supporting both sides and support seat 251 that seat 251 is separately fixed at main body of vehicle frame front end are not less than the bottom surface of towing plate 23, and each support bar 252 correspondence is arranged on one and supports on seat 251.
It is preferred that support seat 251 is in sleeve-shaped, support bar 252 is arranged in the support seat 251 of sleeve-shaped.
Support bar 252 includes: the body of rod 2521 supports sole 2522 with being hinged on the body of rod 2521 bottom one, supports sole 2522 and can strengthen the contact area with ground, improves the stability used.
The Breadth Maximum of the body of rod 2521 is less than supporting the Breadth Maximum of seat 251 inner core and can move up and down in supporting seat 251, support the Breadth Maximum of sole 2522 more than the Breadth Maximum supporting seat 251 inner core, thus when the body of rod 2521 moves up and puts in place, support sole 2522 and can be exposed to support the lower section of seat 251.
Tractor is affected and semitrailer normally mounts for avoiding supporting sole 2522, support seat 251 when mounted, preferably make its bottom surface bottom surface one setpoint distance higher than towing plate 23, this setpoint distance is substantially equal to support the height of sole 2522, thus form a receiving space supporting seat 251 bottom surface, just can accommodate support sole 2522, make support sole 2522 be not less than the bottom surface of towing plate 23 when support bar 252 collapsed state, it is ensured that tractor and semitrailer can normally mount.
