Detailed description of the invention

The exemplary embodiment embodying this utility model feature and advantage will describe in the following description in detail. Iting should be understood that this utility model can have various changes on different embodiments, it is all without departing from scope of the present utility model, and explanation therein and be shown in and be substantially treated as purposes of discussion, and is not used to restriction this utility model.

Below in conjunction with a preferred embodiment, dumper of the present utility model and the structure of vehicle frame, function and principle are described in detail.

Refer to Fig. 1 and Fig. 3, the present embodiment provides a kind of dumper, including traction, vehicle frame and be arranged on the walking mechanism below vehicle frame, this vehicle frame includes the subframe being arranged on chassis, the carriage chassis being arranged on subframe and the platform floor 4 being located on carriage chassis, and the afterbody of carriage chassis and subframe are rotatedly connected so that carriage chassis realizes upset.

Carriage chassis and subframe all include two longerons and are connected between two longerons many spaced crossbeams, namely, carriage chassis includes two carriage chassis longerons 31 and multiple carriage chassis crossbeam 32, and subframe includes two subframe longitudinal beams 21 and multiple chassis cross-member 22. Carriage chassis longeron 31 protrudes downward from carriage chassis crossbeam 32 and the ledge outside fitted in subframe longitudinal beam 21, and the lateral surface of the direct Contact Pair longitudinal beam 21 of medial surface of carriage chassis longeron 31, the upper surface of subframe longitudinal beam 21 directly contacts the lower surface of carriage chassis crossbeam 32. The overall structure of vehicle frame, carriage chassis longeron 31 entire body is outside subframe longitudinal beam 21, the lower aerofoil of carriage chassis crossbeam 32 contacts with the top airfoil of subframe longitudinal beam 21, both the Guan Bi height of vehicle frame had been reduced, reduce again vehicle frame loading end height, prevent vehicle frame from vacillating now to the left, now to the right and the changing of the relative positions, improve dumper operation stability.

Further, the lower surface of carriage chassis longeron 31 inwardly concaves and forms groove, the lower surface of carriage chassis crossbeam 32 inwardly concaves and forms groove, enhance rigidity and the carriage chassis bending resistance when lifting of carriage chassis longeron 31 and carriage chassis crossbeam 32, decrease longeron deformation, improve bearing capacity.

In actual use, the upper surface of carriage chassis longeron 31 can also have and inwardly concaves and form groove, or the upper and lower surface of carriage chassis longeron 31 has above-mentioned groove simultaneously, improves rigidity, to strengthen the bending resistance of carriage chassis longeron 31.

The lateral surface of carriage chassis longeron 31 fixes the wing support 33 connecting multiple horizontally sets, and the wing supports the upper surface level of 33 and supports platform floor 4, and the cross section along its length of wing support 33 is outside in the structure become narrow gradually to vehicle frame by frame interior. Additionally, the lower surface of wing support 33 inwardly concaves and forms groove, improve rigidity, to strengthen the bending resistance of wing support 33. The lower surface of platform floor 4 supports 33 respectively with the wing, the upper surface of carriage chassis longeron 31, carriage chassis crossbeam 32 is welded to form frame structure with carrying from the weight of loading space.

It should be understood that the present embodiment further groove structure, can be support the through setting of length direction along crossbeam, longeron or the wing, it can also be multiple groove that is intervally arranged along its length, each groove is through place beam body all in the width direction, its purpose is for improving the rigidity of crossbeam, longeron or wing support, increases bending resistance.

Referring again to Fig. 2 and Fig. 3, the both sides of carriage chassis rear end are respectively flexibly connected with subframe by a switching mechanism. Switching mechanism includes rotating shaft 51 and axle bed, and the lower end of axle bed is rotatably connected with rotating shaft 51, and upper end is fixing with carriage chassis to be connected. Further, this axle bed includes interior returning face plate 52, outer roll-over panels 53, widens fixed bin 54, lining 55 and parallels 56.

Subframe longitudinal beam 21 is provided with mean for the first through hole that rotating shaft 51 wears.

Outer roll-over panels 53 projects in parallel out and is set in rotating shaft 51 along the lateral surface of carriage chassis longeron 31, interior returning face plate 52 stretch out along carriage chassis and parallel contact in the medial surface of subframe longitudinal beam 21 to being set in rotating shaft 51. Widen fixed bin 54 below carriage chassis longeron 31 and between outer roll-over panels 53 and subframe longitudinal beam 21, and widen fixed bin 54 and transversely run through to arrange and be arranged in the second through hole therein for rotating shaft 51; Wherein, the lower surface of the upper surface and carriage chassis longeron 31 of widening fixed bin 54 has gap, it is to avoid the carriage chassis longeron 31 interference to widening fixed bin 54 in carriage chassis switching process. Parallels 56 is arranged between carriage chassis longeron 31 and interior returning face plate 52, and parallels 56 is positioned at the top of subframe longitudinal beam 21. The setting widening fixed bin 54 and parallels 56 is for being easily installed interior returning face plate 52 and outer roll-over panels 53, and improves the stability of axle bed.

Axle bed also includes the lining 55 running through described first through hole and described second through hole, and rotating shaft 51 is arranged in lining 55.

In sum, carriage chassis entire body, on subframe, reduces loading end height, improves the operating stability of dumper, avoid and when left and right vehicle wheel waves and bear high torque, cause subframe and the dislocation of carriage chassis longeron, it is ensured that the safety that vehicle travels; The groove structure of carriage chassis longeron, crossbeam and wing support, substantially increases rigidity, decreases deformation, enhances bending resistance during vehicle frame lifting.

Although describing this utility model with reference to exemplary embodiment, it is to be understood that, term used is to illustrate and exemplary and nonrestrictive term. The spirit without deviating from utility model or essence can be embodied as in a variety of forms due to this utility model, it is to be understood that, above-mentioned embodiment is not limited to any aforesaid details, and should explain widely in the spirit and scope that appended claims limit, therefore fall into the whole changes in claim or its equivalent scope and remodeling all should be appended claims and contained.
