technical field:
The utility model relates to the locking a door of a kind of carriage back door, door opener, automatically the locking a door of especially a kind of dump truck cabin rear door, door opener.
background technology:
At present, the locking a door of known dump truck cabin rear door, door opener have two kinds, and one is manual lock door gear, and another kind is that hydraulic driven is locked a door automatically, door opener.So-called manual unit is that carriage back door is provided with hook and locker, first hangs up hook at closing time, then lock locker with hand, opens the door, closes the door and be very inconvenient, the large inefficiency of driver's working strength.Hydraulic driven is locked a door automatically, door opener is convenient and strength-saving, and efficiency is high, but needs outputting power, consumes the energy, does not meet the requirement of energy-conserving and environment-protective, complex structure, and price is high, and maintenance difficulty is large.Therefore, the convenience of some dumping car in order to unload, simply removes carriage back door or does not design carriage back door, causes cargo capacity few, in transit easy cargoes from scattering.
summary of the invention:
The purpose of this utility model is to provide when one can rise in compartment and automatically opens carriage back door, automatically the locking a door of the dump truck cabin rear door of auto lock carriage back door, door opener after compartment falls.
For achieving the above object, the technical solution adopted in the utility model is:
Automatically the locking a door of a kind of dump truck cabin rear door, door opener, comprise tapered end, connecting rod, U-shaped fork, locking wrench, it is characterized in that: tapered end, connecting rod, U-shaped fork, locking wrench connect in turn, form automatically the locking a door of dump truck cabin rear door, door opener, be arranged on the both sides of body of tipper carriage bottom.
According to automatically the locking a door of described dump truck cabin rear door, door opener, it is characterized in that: described tapered end is hook-type, comprise gib head and the neck of hook, the neck of hook is provided with two axis holes of size, little axis hole is connected with connecting rod by bolt, on the pivot pin that large shaft hole sleeve below little axis hole welds at cabin floor front end, tapered end can freely rotate around pivot pin.
According to automatically the locking a door of described dump truck cabin rear door, door opener, it is characterized in that: the other end of described connecting rod is that screw mandrel is connected with U-shaped fork, and screw mandrel is provided with setting nut between pitching with U-shaped, in order to regulate the length between tapered end and locking wrench.
According to automatically the locking a door of described dump truck cabin rear door, door opener, it is characterized in that: described U-shaped fork is U-shaped, two open ends are respectively provided with an aperture, by bolt, be connected with locking wrench, the bottom of U-shaped fork is provided with screw hole, is connected with the screw mandrel of connecting rod.
According to automatically the locking a door of described dump truck cabin rear door, door opener, it is characterized in that: described locking wrench is angle bar shape, endways one end is provided with an aperture, by bolt, is connected with U-shaped fork, corner is provided with a larger axis hole, is arranged on the anchor shaft of car bottom.
According to automatically the locking a door of described dump truck cabin rear door, door opener, it is characterized in that: on the main car frame of described locking wrench below, be respectively provided with an arch roof pressing plate, push down the other end of locking wrench, before the endways one end of locking wrench, be respectively provided with a limit shaft, the amplitude that limitation lock spanner opens.
The beneficial effects of the utility model are that simple structure, installs easily, price is low, and long service life is saved the energy, do not need additionaling power, entirely by the self gravitation of automatically the locking a door of compartment and dump truck cabin rear door, door opener, complete automatically the action of locking a door, open the door.In the time of rising in compartment, automatically open carriage back door, auto lock carriage back door after compartment falls, has reduced driver's operating sequence, has improved the work efficiency of dumping car.
accompanying drawing explanation:
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing 1 is structural representation of the present utility model.
1 tapered end, 2 connecting rods, 3U shape fork, 4 locking wrenchs, 5 setting nuts, 6 top pressing boards, 7 carriage back doors, 8 cabin floors, 9 main car frames, 10 limit shafts in figure.
the specific embodiment:
In the drawings, automatically the locking a door of a kind of dump truck cabin rear door, door opener, comprise tapered end 1, connecting rod 2, U-shaped fork 3, locking wrench 4, it is characterized in that: tapered end 1, connecting rod 2, U-shaped fork 3, locking wrench 4 connect in turn, form automatically the locking a door of dump truck cabin rear door, door opener, be arranged on the both sides of body of tipper carriage bottom.Tapered end 1 is hook-type, comprises gib head and the neck of hook, and the neck of hook is provided with two axis holes of size, and little axis hole is connected with connecting rod 2 by bolt, and on the pivot pin that the large shaft hole sleeve below little axis hole welds at cabin floor front end, tapered end 1 can freely rotate around pivot pin.The other end of connecting rod 2 is that screw mandrel is connected with U-shaped fork 3, is provided with setting nut 5, in order to regulate the length between tapered end 1 and locking wrench 4 between screw mandrel 1 and U-shaped fork 3.U-shaped fork 3, is U-shaped, and two open ends are respectively provided with an aperture, by bolt, is connected with locking wrench 4, and the bottom of U-shaped fork 3 is provided with screw hole, is connected with the screw mandrel of connecting rod 2.Locking wrench 4 is angle bar shape, and endways one end is provided with an aperture, by bolt, is connected with U-shaped fork 3, and corner is provided with a larger axis hole, is arranged on the anchor shaft of car bottom.On the main car frame 9 of locking wrench 4 belows, be respectively provided with an arch roof pressing plate 6, push down the other end of locking wrench 4, before the endways one end of locking wrench 4, be respectively provided with a limit shaft 10, the amplitude that limitation lock spanner 4 opens.
Principle of work: when self-discharging carriage rises certain altitude, locking wrench 4 leaves top pressing board 6, under the gravity of tapered end 1 self, tapered end 1 falls, carriage back door 7 is opened, limit shaft 10 blocks locking wrench 4, prevents that the amplitude that locking wrench 4 opens is excessive, to can be crushed on top pressing board 6 when falling after rise again.When falling compartment, locking wrench 4 is compressed by top pressing board 6, by straining at connecting rod 2 by tapered end 1 pull-up, pins carriage back door 7.
