Description

The no subframe lifting structures of a kind of dumping car
Technical field
The utility model belongs to the dumping car technical field, relates to the no subframe lifting structures of a kind of dumping car concretely.
Background technology
Existing dumping truck mostly adopts one of following several lifting mechanisms:
1, twin-tub direct pushing machine structure
When there is subframe in this mechanism, car load center of gravity height, lateral stability is poor, causes the rollover accident easily; During no subframe, then oil cylinder stroke is long, and the ground Clearance is little, and crossing ability is poor, only is suitable for the good road surface transportation, is not suitable for occasions such as building site, mine.This train of mechanism pressure maximum, to compartment longeron requirement of strength height, otherwise, easy deformation.
2, the compound lifting mechanism of T formula
The existing compound lifting mechanism of T formula system initial pressure is big, and weight is heavier, and cylinder pedestal is stressed big, and is higher to the vehicle frame rigidity requirement, toughness deficiency, vehicle frame fault rate height.
3, subframe F formula lifting support is arranged
Superpose on main car frame in this structure and be provided with the subframe that is used to install F formula lifting support, subframe makes this mechanism's quality big, the cost height, and charge material amount factor of utilization is low, the oil consumption height; Car load center of gravity height, riding stability are poor, particularly turn in the driving process and very easily cause the rollover accident.During this mechanism lifting lifting levelling of the land degree is required high, otherwise, rollover easily.
The utility model content
The purpose of this utility model has been to provide a kind of and has cancelled subframe and adopt F formula lifting support can guarantee the no subframe lifting structures of dumping car of frame strength rigidity simultaneously.
The technical solution of the utility model is as follows:
The no subframe lifting structures of a kind of dumping car, comprise vehicle frame, the compartment, strength beam, vibration damper steel plate hanger and F formula lifting support, described strength beam is provided with near described vibration damper steel plate hanger, wherein said F formula lifting support is by elevating ram, tie rod and triangle arm are formed, three angles of described triangle arm are point of connection, one end of described tie rod and first point of connection of described triangle arm are hinged, it is hinged that the tie rod that the other end and bottom surface, compartment are provided with is connected journal stirrup, one end of described elevating ram and second point of connection of described triangle arm are hinged, it is hinged that the oil cylinder that the other end and bottom surface, compartment are provided with is connected journal stirrup, between the left-right longeron of described vehicle frame, be provided with support beam, this support beam middle part is provided with the triangle arm and connects journal stirrup, the 3rd point of connection of described triangle arm is hinged on described triangle arm and connects on the journal stirrup, and the two ends of described support beam are connected with described vehicle frame by the flute profile connecting panel.
Adopt said structure to provide a hinged strong point by the triangle arm that is designed to of support beam, simultaneously for to guarantee that the rigidity at the support beam place of connecting to ground and intensity are provided with the flute profile connecting panel, realized like this cancellation subframe after the application of F formula lifting support on main car frame, and guarantee the strength and stiffness of main car frame behind the cancellation subframe, improve distribution of stress, prevent fracture, improve vehicle frame service life.Thereby can play reduction car load center of gravity raising riding stability after cancelling subframe simultaneously.
The two ends of described strength beam are connected with the left-right longeron of described vehicle frame by brace panel.
Be connected with vibration damper steel plate on the vibration damper steel plate hanger, this zone is subjected to concentrated force bigger, guarantees the rigidity and the intensity of this junction by setting up brace panel.
The cross-sectional plane of described support beam is a rectangle, the welding of this support beam and described flute profile connecting panel, this flute profile connecting panel base fall in the groove of described vehicle frame left-right longeron and with its riveted joint.
The riveted joint of flute profile connecting panel and vehicle frame left-right longeron has solved the flexible problem of vehicle frame distortion, support beam and flute profile connecting panel be welded to connect the stiff problem that has then solved the huge hoisting force of crossbeam when vehicle frame directly bears the compartment by lifting, thereby satisfied the operating needs of car load.
Described brace panel extend to described vibration damper steel plate hanger and with the join domain of flute profile connecting panel.
Described brace panel is a channel-section steel, and the outer rim of this channel-section steel is a triangle, the base drop in the groove of described vehicle frame left-right longeron and with its riveted joint, side and the riveted joint of described strength beam, the overlap-add region of described brace panel and described flute profile connecting panel is riveted.
Beneficial effect: the utility model has been realized the cancellation subframe by the improvement to vehicle frame and has been adopted F formula lifting support can guarantee frame strength rigidity simultaneously, reduced the car load center of gravity, improve roadability.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the connection diagram of F formula lifting support and vehicle frame;
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
Embodiment: as Fig. 1,2, shown in 3: the no subframe lifting structures of a kind of dumping car, comprise vehicle frame 1, compartment 2, strength beam 8, vibration damper steel plate hanger 9 and F formula lifting support, described strength beam 8 is provided with near described vibration damper steel plate hanger 9, wherein said F formula lifting support is by elevating ram 3a, tie rod 3b and triangle arm 3c form, three angles of described triangle arm 3c are point of connection, first point of connection of the end of described tie rod 3b and described triangle arm 3c is hinged, it is hinged that the tie rod that the other end and 2 bottom surfaces, compartment are provided with is connected journal stirrup 4, second point of connection of the end of described elevating ram 3a and described triangle arm 3c is hinged, it is hinged that the oil cylinder that the other end and 2 bottom surfaces, compartment are provided with is connected journal stirrup 5, between the left-right longeron of described vehicle frame 1, be provided with support beam 6, these support beam 6 middle parts are provided with the triangle arm and connect journal stirrup 7, the 3rd point of connection of described triangle arm 3c is hinged on described triangle arm and connects on the journal stirrup 7, and the two ends of described support beam 6 are connected with described vehicle frame 1 by flute profile connecting panel 11.
