Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

A kind of telescopic skid-steer loader working device, comprises scraper bowl 1, dump ram 2, swing arm 3, boom cylinder 4 and vehicle frame 5, and described scraper bowl 1 is articulated with A point with swing arm 3; Described dump ram 2 one end and scraper bowl 1 are articulated with B point, the other end be articulated with C point with swing arm 3; Described boom cylinder 4 one end and swing arm 3 are articulated with D point, and the other end and vehicle frame 5 are articulated with E point; Described swing arm 3 is articulated with F point with vehicle frame 5; Described swing arm 3 is stretching structure, and it comprises guiding swing arm 31, work swing arm 32, telescopic oil cylinder 33 and alignment pin 34, and described guiding swing arm 31 is articulated with F point, D point respectively with vehicle frame 5, boom cylinder 4; Described work swing arm 32 is articulated with A point with scraper bowl 1; Described telescopic oil cylinder 33 one end is articulated with F point with guiding swing arm 31, and the other end is articulated with G point with work swing arm 32; During non-elongate state, described guiding swing arm 31 is articulated with F point with vehicle frame 5, and described alignment pin 34 locks guiding swing arm 31 and work swing arm 32, and it, away from D point, is positioned at the rear portion of F point.Described guiding swing arm 31 is U-shaped with the cross section of work swing arm 32 overlapping region; Described work swing arm 32 is N-shaped with the cross section of guiding swing arm 31 overlapping region, and its afterbody has a U-type groove, and channel opening, towards F point, is convenient to the relative motion of guiding swing arm 31 and work swing arm 32 with this.According to lever principle, the arm of force is longer, institute is stressed less, in order to improve the reliability of service load and mechanism, the elongation of telescopic oil cylinder 33 is made to be L1, guiding swing arm 31 is L2 with the length of work swing arm 32 overlapping region, and the numerical relation of described L1 and L2 is: L1 < L2, and the cylinder body end of telescopic oil cylinder 33 and vehicle frame are articulated with F point.Making D point be L3, G point be L4, C point to F point along the distance in swing arm direction to F point along the distance in swing arm direction is L5 to F point along the distance in swing arm direction, and the numerical relation of described L3, L4 and L5 is: L3 < L4 < L5.

When the equipment of radial lifting just can meet the discharge height needed for operating mode and unload distance, do not take out alignment pin 34, now, equipment of the present utility model is the equipment of radial lifting.When operating mode needs larger discharge height and unloading distance, take out alignment pin 34, now, equipment of the present utility model is the equipment of similar vertical lifting, but due to the mating reaction of boom cylinder 4 and telescopic oil cylinder 34, it can significantly improve discharge height and unloading distance, reaches real vertical lifting, and has some functions of telescopic arm forklift truck.

Although be described in detail the utility model above in conjunction with the embodiments; but described those skilled in the art can understand; under the prerequisite not departing from present inventive concept, can also change above-described embodiment or change etc., still drop in protection domain of the present utility model.
