The specific embodiment

Extremely shown in Figure 8 as Fig. 1, the utility model integrated hydraulic rear carriage plate type self-discharging carriage, comprise envelope 1 and bonnet 2, wherein, be respectively arranged with support bracket 3 on the both sides of envelope 1 rear end, the top of support bracket 3 is hinged with pivot arm 4, pivot arm 4 is the U-shaped structure, it comprises left side arm 41, right arm 42 and postbrachium 43, left side arm 41, all along the length direction setting of envelope 1, postbrachium 43 is arranged on the top of bonnet 2 to right arm 42, by pivot arm 4 is set to the U-shaped structure, improved the structural strength of pivot arm 4, and improved when promoting bonnet 2 synchronism that bonnet 2 both sides are raised by pivot arm 4.The vertical section of left side arm 41, right arm 42 and postbrachium 43 is ∩ shape structure, and it constitutes by side plate 8, side plate 9 and upper cover plate 10.Support bracket 3 is arranged within the space that side plate 8, side plate 9 and upper cover plate 10 surrounded.Be provided with lifting device 7 between the bottom of support bracket 3 and the pivot arm 4, lifting device 7 is hydraulic actuating cylinder or air cylinder, lifting device 7 also is arranged within the space that side plate 8, side plate 9 and upper cover plate 10 surrounded, by support bracket 3 and lifting device 7 being arranged within the space that side plate 8, side plate 9 and upper cover plate 10 surrounded, can prevent that support bracket 3 and lifting device 7 are in loading, unloading goods or transportation, by the goods scratch, break etc., it has improved the service life of support bracket 3 and lifting device 7.Under the lifting force effect of lifting device 7, pivot arm 4 can be around the rotation of its hinge-point, thus the rear end of the pivot arm that is 4 lift, open bonnet 2, to increase the unloading outlet in compartment.Also be provided with latch hook 13 on the bottom of envelope 1, when bonnet 2 is fastened on envelope 1 rear end, the lower end that latch hook 13 pins bonnet 2, when needs were unloaded, latch hook 13 was opened automatically.

The afterbody of pivot arm 4 is provided with L shaped pull bar 5, the bending mouth direction of L type pull bar 5 is for upwards being provided with, and place, inflection point, pull bar 5 middle part is articulated and connected with pivot arm 4, pull bar 5 can rotate flexibly around its hinge-point, one end of pull bar 5 is captiveed joint with bonnet 2, and the other end of pull bar 5 is fixedly connected on the side plate of envelope 1 by hinge 6.The rear end of pivot arm 4 is provided with projection 11, and when bonnet 2 was fastened on envelope 1 rear end, bonnet 2 was resisted against on the projection 11.

For the hydraulic actuating cylinder that prevents lifting device 7 or air cylinder after lifting; hydraulic actuating cylinder or air cylinder easily by the goods scratch in the envelope 1, phenomenon such as break; the position of the close support bracket 3 of envelope side plate is provided with backplate 12; backplate 12 is fixedly connected on the inwall of envelope side plate; and the height of backplate 12 is not less than the height of support bracket 3; backplate 12 actvies have been protected lifting device 7; improved its service life; and backplate 12 also can effectively be protected support bracket 3, and it has prevented to make that owing to support bracket 3 is hit to bend pivot arm 4 can't be by the phenomenon of lifting.

During work, lifting device 7 lifts the rear end of pivot arm 4 earlier, and pivot arm 4 will be around its hinge-point rotation, and pull bar 5 also will be picked up, thereby make bonnet 2 be picked up.Length owing to bonded assembly hinge 6 on the pull bar 5 is what limit simultaneously, because the length of hinge 6 can not be extended, under the limitation of length of hinge 6, hinge 6 pulling pull bars 5 are around its hinge-point rotation, so that bonnet 2 opens certain angle under the rotation of pull bar 5 like this.Bonnet 2 not only can open under the kicking up of pivot arm 4 rear ends in the present embodiment, can also further open certain angle under the rotation of pull bar 5, thereby has increased the unloading outlet in compartment more.The envelope front end is by front end high pressure lifting device jack-up subsequently, and goods will draw off from the envelope rear end.

The utility model is by being provided with support bracket 3, made things convenient for the installation of back railway carriage or compartment bucket 2 and lifting device 7, and improved support strength to bonnet 2 and lifting device 5, simultaneously, because support bracket 3 has certain height, bonnet 2 is after being propped on the basis of support bracket 3 like this, and the lift height of bonnet 2 will be higher, thereby further increases the unloading outlet in compartment.The utility model is convenient to the unloading of bulk goods, improves the speed of unloading, improves conveying efficiency.And of the present utility model simple in structure, be beneficial to the transformation of used car.

As Fig. 9, shown in Figure 10, the utility model integrated hydraulic rear carriage plate type self-discharging carriage, can directly bonnet 2 be articulated and connected on pivot arm 4, the position of its hinge-point can be according to the actual requirements, be arranged on the top or the bottom of pivot arm, after lifting device 7 lifts the rear end of pivot arm 4, bonnet 2 also will be picked up.
