The specific embodiment
Hereinafter also describe in conjunction with the embodiments the utility model in detail with reference to accompanying drawing.Need to prove, in the situation that do not conflict, embodiment and the feature among the embodiment among the application can make up mutually.
As shown in Figures 1 to 4, according to embodiment of the present utility model, a kind of High Altitude Platform Operation Van comprises vehicle frame, rotary table and climbing support 10, and wherein rotary table is arranged on the vehicle frame rotationally, and climbing support 10 liftably is arranged on the rotary table.Climbing support 10 can be ladder or jib.
The working end of climbing support 10 is provided with working bucket 20, levelling gear 30 and driver train 40, wherein working bucket 20 is connected to the end, working end of climbing support 10 turningly, levelling gear 30 is connected with working bucket with climbing support 10 respectively and is connected, driver train 40 can directly drive with working bucket 20 and be connected, and cooperate with levelling gear 30, realize leveling and the upset of working bucket 20, also can drive and be connected to levelling gear 30, by the action control of control levelling gear 30 realizations to working bucket 20.
In the present embodiment, levelling gear 30 comprises leveling cyclinder 31 and connecting rod, and the first end of leveling cyclinder 31 is hinged to climbing support 10, the second ends and is connected with the connecting rod driving.Connecting rod comprises first connecting rod 32, second connecting rod 33 and third connecting rod 34, and wherein the first end of first connecting rod 32 is fixedly connected on the end, working end of climbing support 10, and the second end is hinged on the working bucket 20.The first end of second connecting rod 33 is hinged on the telescopic end end of leveling cyclinder 31, and the second end is hinged on the bottom of working bucket 20, and is positioned at the below of the hinge-point of first connecting rod 32.The first end of third connecting rod 34 is hinged on the telescopic end end of leveling cyclinder 31, and the second end is hinged on the middle part of first connecting rod 32.Third connecting rod 34 can be identical with the hinge of second connecting rod 33 in the telescopic end end of leveling cyclinder 31.
When leveling cyclinder 31 carries out expanding-contracting action, drive second connecting rod 33 actions.Because third connecting rod 34 is connected between first connecting rod 32 and the second connecting rod 33, under the connection function of third connecting rod 34, the telescopic end of leveling cyclinder 31 rotates around the hinge of third connecting rod 34 on first connecting rod 32 take the length of third connecting rod 34 as the radius of gyration.Under the induced effect of leveling cyclinder 31, an end of second connecting rod 33 is with leveling cyclinder 31 motions, and the other end drives working bucket 20 motions.First connecting rod 32 is fixedly connected on the climbing support 10, the hinge of itself and working bucket 20 is fixing hinge, when therefore second connecting rod 33 moves, can drive working bucket 20 and rotate around the hinge of first connecting rod 32 with working bucket 20, thus leveling and the rotary movement of realization working bucket 20.
In the middle of a unshowned embodiment, levelling gear 30 comprises first connecting rod 32 and leveling cyclinder 31, the first end of first connecting rod 32 is fixedly connected on the end, working end of climbing support 10, the second end of first connecting rod 32 is hinged on the working bucket 20, the first end of leveling cyclinder 31 is hinged on the climbing support 10, and the second end is hinged on the working bucket 20.When leveling cyclinder 31 is made expanding-contracting action, because the restriction of first connecting rod 32, working bucket 20 is merely able to rotate around the hinge of itself and first connecting rod 32, by the expanding-contracting action of control linkage at the telescopic end of the leveling cyclinder 31 of working bucket 20 bottoms, just can make working bucket 20 realize leveling and rotary movement.
Be connected for the ease of between working bucket 20 and connecting rod and the leveling cyclinder 31, can be fixedly connected with connecting panel in the bottom of working bucket 20, connecting rod and leveling cyclinder 31 all are fixedly connected on the connecting panel.Preferably, connecting panel is L shaped bending plate, and a bending edges of L shaped bending plate is fixedly connected on the diapire of working bucket 20, and another bending edges is fixedly connected on the sidewall of working bucket 20.
Between leveling valve 43 and leveling cyclinder 31, balance cock 44 can also be set, to guarantee the steady action of leveling cyclinder 31.The quantity of leveling cyclinder 31 can be adjusted according to practical situations, in addition, can also check valve, line filter and return filter etc. be set at hydraulic tubing, to improve further the serviceability of hydraulic drive mechanism 40.
The setting position of each parts in the present embodiment and shape all can suitably be adjusted according to the service condition of reality.
In addition, the end, working end of climbing support 10 also can removably connect a working bucket erecting frame, and working bucket 20, levelling gear 30 and driver train 40 all can be fixedly installed on this working bucket erecting frame.This kind structure is convenient to working bucket 20 and leveling system thereof are carried out Assembly ﹠Disassembly more, also more is convenient to change, and uses convenient.
When work, driving pump 42 oil suction from hydraulic reservoir 41, and produce pressure oil.Handle leveling valve 43, can make pressure oil enter leveling cyclinder 31, and pushing piston and piston rod movement, thereby make working bucket 20 upset and the leveling that are hinged on the second connecting rod 33.
From above description, can find out, the utility model the above embodiments have realized following technique effect: the working bucket that High Altitude Platform Operation Van comprises liftable climbing support and is arranged on the end, working end of climbing support, the working end of climbing support also are provided with levelling gear and the driver train of control working bucket action.Because the levelling gear of control working bucket action and the driver train of driving levelling gear all are arranged on the end, working end of climbing support, therefore greatly having reduced levelling gear is connected with pipeline between the driver train, reduced loss of pressure, the speed of response of levelling gear is faster, regulates sensitiveer.Owing to being arranged near the levelling gear between the driver train, therefore need not to consider the impact on other system, structure is simpler, installs also convenient.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
