Detailed description of the invention
For knowing the technical characterstic that this programme is described, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in FIG. 1 to 3, this utility model includes frame 1, is provided with guide groove in the rear end of frame 1, is provided with the tail-gate 2 being slidably connected with it in guide groove, and tail-gate 2 is connected with frame 1 by hoist cylinder 3.Hoist cylinder 3 is two, and is arranged at the left and right sides of tail-gate 2.The cylinder barrel end of hoist cylinder 3 is articulated with in the frame 1 above tail-gate 2, and the cylinder rod end of hoist cylinder 3 is articulated with on tail-gate 2.Be provided with connecting hole 4 in tail-gate 2 upper end, connecting hole 4 is two, and is arranged at the left and right sides of tail-gate 2 upper end.Being connected with rotation bar 5 in the frame 1 between the cylinder barrel end and tail-gate 2 top of hoist cylinder 3, rotate and be fixed with the hook 6 matched with connecting hole 4 on bar 5, hook 6 is two, and two hooks 6 are arranged on the rotation bar 5 positive corresponding with two connecting holes 4.Rotate bar 5 to be connected with the tumbler 7 making it rotate.Tumbler 7 includes connecting plate 701, and one end of connecting plate 701 is connected with rotating bar 5, and the other end of connecting plate 701 is hinged with the cylinder rod end of telescopic oil cylinder 702, and the cylinder barrel end of telescopic oil cylinder 702 is hinged with the bracer 703 being connected in frame 1.In order to ensure connecting plate 701 and rotate the intensity that bar 5 is connected, one end of connecting plate 701 is welded with rotating bar 5.
This utility model controls to rotate bar 5 by tumbler 7 and rotates, the hook 6 on rotation bar 5 is made to hang on the connecting hole 4 of tail-gate 2 upper end, so that long-time firm hang-up after milling machine tail-gate 2 rise, so that workman is to the internal maintenance in milling storehouse, effectively solve the potential safety hazard because electrohydraulic system fault causes, avoid the tail-gate 2 long-term stress of hoist cylinder simultaneously, extend its service life.
Connecting hole 4 and hook 6 are two, further ensure the fixing that tail-gate 2 is hung up.
Tumbler 7 can also be rotary handle, controls to rotate the rotation of bar 5 by manpower.
nullWhen tail-gate 2 is promoted and hangs up by needs，First pass through control device and control three-position four-way electromagnetic directional valve I 8 right position access system，Telescopic oil cylinder 702 rodless cavity fuel feeding promotes rotation bar 5 to turn clockwise (from left sides)，Make to be welded in the hook 6 rotated on bar 5 to rotate with，Rise for tail-gate 2 and vacate space，Then by controlling the device unidirectional electromagnet cut off valve 10 of control left position access system，Control the right position of three-position four-way electromagnetic directional valve II 9 and access system，Hoist cylinder 3 rod chamber fuel feeding promotes tail-gate 2 until it is minimum point during vertical state that tail-gate 2 upper end connecting hole 4 crosses hook 6，Then by controlling device control three-position four-way electromagnetic directional valve I 8 left position access system，Telescopic oil cylinder 702 rod chamber fuel feeding drives rotation bar 5 to rotate (by left sides) counterclockwise until hook 6 lower ends fully extend in the connecting hole 4 of tail-gate 2 upper end，Then control the left position of three-position four-way electromagnetic directional valve II 9 and access system，Telescopic oil cylinder 702 rodless cavity fuel feeding decline tail-gate 2，Hang on hook 6 until tail-gate 2 upper end connecting hole 4 is firm，Then control position in three-position four-way electromagnetic directional valve II 9 and three-position four-way electromagnetic directional valve I 8 and access system，This process remaining, system is accessed in the left position of unidirectional electromagnet cut off valve 10，Namely the whole process of tail-gate 2 automatic lifting firm hang-up is completed.When tail-gate 2 needs to cancel hang-up and when declining, its each parts sequence of movement and tail-gate 2 hang up process contrast, are tail-gate 2 inverse process that promote and hang up, do not repeat herein.
Above-mentioned detailed description of the invention cannot function as the restriction to this utility model protection domain, and for those skilled in the art, any alternate modification made to this utility model embodiment or conversion all fall within protection domain of the present utility model.
