Abstract

The utility model relates to a balancing frame at the outer part of a self-dumping truck, which comprises an upper frame and a lower frame. The utility model is characterized in that the upper frame and the lower frame are respectively divided into two independent sections, and the structures of the upper frame and the lower frame adopt enclosed type tubular type structures, the two sections of the lower frame are mutually communicated through a penetrating axle, the two sections of the upper frames are respectively arranged at the outer sides of the two sections of the lower frame, and the end of each section of the upper frame is connected with the corresponding end of the lower frame through minor axle to form a connecting rod structure. The balancing frame has the advantages that structurally the traditional balancing supporting frame which is suitable for being installed on the girder of the frame and at the inner side of a sub frame is changed into a structure which is suitable for being installed at the outer side of the sub frame, therefore the installation position of the traditional balancing supporting frame is changed, so as to ensure the position of a supporting point to be more close to the front end of a cage body and the outer width, the space length between the balancing supporting frame and an overturning axle and the self transverse pitch of the balancing supporting frame are increased, the transverse stability of the vehicle is effectively improved, the hoisting stability of the vehicle is enhanced, and the roll-over phenomenon of the vehicle during the hoisting process is effectively avoided.

Description

Dumping car external balance frame

Technical field: the utility model relates to a kind of dumping car external balance frame, belongs to the dumping car field of components.

Background technology: the arrangement of the balance bracket of present domestic dumping truck is frame beam and subframe inboard, so its structure design also is for adapting to this arrangement design-calculated, because the restriction of its structure, it is nearer to be installed on the dumping car rear fulcrum and trip shaft, and laterally span is short, when dumper skip is longer, stabilization is not obvious, because the operation operating mode of discharging vehicle is poor, the phenomenon of vehicle rollover when once lifting taking place has caused economic loss for user and main engine plants.

Summary of the invention: the purpose of this utility model provides a kind of spacing that can strengthen between balance fulcrum and the trip shaft, increase the horizontal span between the equalizer bar, effectively improve the lifting stability of the lateral stability and the raising vehicle of vehicle, the dumping car external balance frame of effectively avoiding vehicle when lifting, to turn on one's side.

The objective of the invention is to be achieved through the following technical solutions:

Dumping car external balance frame of the present utility model comprises puts on the shelf and undercarriage, it is characterized in that: put on the shelf and undercarriage respectively have independently two sections, every section upper and lower structure is case type tubular structure, two sections undercarriages are connected by a thru shaft, put on the shelf for two sections and be located at the outside of two sections undercarriages respectively, its each section is put on the shelf all has a termination to connect into bar linkage structure with minor axis with the corresponding termination of undercarriage.

The utility model has the advantages that: the balance bracket that structurally traditional being fit to is installed in frame beam and subframe inboard has made to be suitable for the structure of installation outside subframe into, thereby installing the installation site that has changed the conventional balanced support, by the dumping car balance bracket being arranged in the vehicle frame outside, the position that makes fulcrum is more near envelope front end and outer wide place, the spacing of balance bracket and trip shaft and the transverse pitch of balance bracket self have been strengthened, effectively improved the lateral stability of vehicle, improve the lifting stability of vehicle, avoided the vehicle phenomenon of when lifting, turning on one's side to take place effectively.

Description of drawings: Fig. 1 is the structural representation of external balance support of the present invention;

Fig. 2 is the birds-eye view of Fig. 1.

The specific embodiment: with reference to accompanying drawing, balance bracket 1 of the present utility model is divided into puts 3 and undercarriage 7 two parts on the shelf, put on the shelf 3 and undercarriage 7 respectively have independently two sections, every section upper and lower structure is case type tubular structure, two sections undercarriages 7 are connected by a thru shaft 9, two sections 3 outsides that are located at two sections undercarriages 7 respectively of putting on the shelf, its each section is put on the shelf all has a termination to connect into bar linkage structure with minor axis 5, axle sleeve 6 with the corresponding termination of undercarriage.When on dumping car, installing, put 3 on the shelf in the outside, fixing with two axles 2 respectively with the bearing 11 of dump truck van floor beam 10 two ends welding.Undercarriage 7 is connected with subframe 9 by thru shaft 8 in the inboard, is installed in the outside of subframe 9.The axle head of all must be installed alemite 4.When vehicle ', balance bracket 1 put on the shelf 3 and undercarriage 7 two parts be folded state.

During the dump truck van lifting, but put on the shelf 3 and undercarriage 7 be pivot point anticlockwise direction rotation with axle 2,3 liftings of following envelope of putting on the shelf simultaneously are that pivot point can be opened along clockwise direction with respect to undercarriage 7 with minor axis 5.
