Description
Technical field:
The utility model relates to Transport Appropriation Rolling Stock technical field, particularly the tipper lifting mechanism of the large corner of a kind of little stroke.
Background technology:
Dumping car refers to and a set of hydraulic efficiency pressure system is housed, and compartment can be tilted to certain angle, can rely on a class vehicle of gravity unloaded of cargo voluntarily.For nation, environmental sanitation greening or garbage transporting etc., as: tumbrel, mine dumping car, refuse tipper, Coal Transport dumping car etc.Dumping car comprises general truck engine, chassis and operator's compartment, also has the mechanisms such as hydraulic lifting mechanism, tiltable compartment and power takeoff in addition.
Hydraulic lifting mechanism design generally has two schemes: 1, vertically install on the end wall of operator's compartment one end in compartment; 2, the attached vehicle frame under compartment is installed; There is following problem at present in the design in scheme 2: in order to ensure flip angle, and hydraulic actuating cylinder need adopt long, and between the region that two crossbeams that long hydraulic actuating cylinder is not easy to be contained in attached vehicle frame are separated; Like this, or increase the spacing of crossbeam, or during non-unloading, compartment can not be set level completely on attached vehicle frame.No matter which kind of mode all can cause vehicle body built on the sand above.
Summary of the invention:
Given this, the tipper lifting mechanism designing the large corner of a kind of folding little stroke is necessary.
A tipper lifting mechanism for the large corner of little stroke, comprising: load lifting cylinder, support arm, draw high arm, attached vehicle frame; Wherein, on the sidewall that support arm fixed end is articulated in attached cross member of frame and this sidewall is side near operator's compartment, support arm fixed end can only pivotally rotate, and cannot relatively attached vehicle frame lifting, the other end of support arm is support arm lifting end, support arm lifting end and the pivot joint of load lifting cylinder one end, the load lifting cylinder other end and car bottom pivot joint, load lifting cylinder is by changing the length at its two ends thus to compartment acting, realizing the inclination in compartment; Support arm lifting end also with draw high the pivot joint of arm movable end, draw high the arm other end for drawing high arm fixed end, drawing high arm fixed end is articulated on car bottom, and draw high arm fixed end comparatively load lifting cylinder and car bottom articulated section closer to compartment afterbody, draw high arm fixed end to rotate around its pivot, and cannot relatively compartment away from or close, the distance between load lifting cylinder two drive-connecting shaft (namely under the complete contraction state of load lifting cylinder) under its non-workmanship state is less than the distance drawn high between arm two drive-connecting shaft; Support arm resettlement section is provided with near operator's compartment side at the aforementioned crossbeam of attached vehicle frame, load lifting cylinder is positioned at support arm resettlement section in non-workmanship state lower branch arm lifting end major part, the part being meant to support arm lifting end protrusion support arm resettlement section of aforementioned " major part " should be less than the half of support arm lifting end end height, and the height point of support arm lifting end projection is not higher than the horizontal surface drawing high arm fixed end vertex place; The benefit of such setting is the whole height that can reduce compartment and attached vehicle frame under the prerequisite not changing compartment physical dimension, compartment and attached vehicle frame are combined more firmly and reduce dumping car center of gravity.
Attached vehicle frame is fixed in dumper frame, compartment tail end is hinged on attached vehicle frame afterbody, when starting load lifting cylinder and starting to tilt compartment, load lifting cylinder extends promotion compartment and upwards rotates, drive while compartment rotates and draw high arm fixed end and move, and then haul support arm upwards rotate by drawing high arm, that is: make load lifting cylinder also move to same direction together, thus decrease the stroke of load lifting cylinder.
Preferably, support arm is a pair and be arranged in parallel, and load lifting cylinder and support arm articulated section, between this is to support arm, is drawn high arm and are all be arranged in parallel a pair, the support arm lifting end pivot joint drawing high arm and its side, place of every side.
Preferably, the pivot of support arm and attached vehicle frame is the first pivot, the pivot of support arm and load lifting cylinder is the second pivot, support arm is the 3rd pivot with the pivot drawing high arm, the angle of the first pivot, the second pivot, the 3rd pivot line is greater than 0 degree and is less than 180 degree, and the 3rd pivot is positioned at compared with the second pivot closer to compartment place.Load lifting cylinder and the angle that draws high between arm when the advantage of setting like this is to increase non-dumping; Although the pivot of load lifting cylinder and car bottom and the pivot not conllinear drawing high arm and car bottom, even if the second pivot, the 3rd pivot axles being collinear can be guaranteed in theory, when non-dumping load lifting cylinder with draw high arm can not be parallel (parallel, can cause and rotate dead point, no matter load lifting cylinder exports much power, all cannot promote compartment in this to rotate), but the output that when increasing non-dumping by such design, load lifting cylinder and the angle drawn high between arm can be relatively little promotes heavier compartment and rotates.
Preferably, distance between load lifting cylinder two drive-connecting shaft is draw high arm two drive-connecting shaft spacing 4/5 ~ 6/7 under its non-workmanship state, the angle of the first pivot, the second pivot, the 3rd pivot line is 90 ~ 110 degree, and the distance between the second pivot and the 3rd pivot is draw high arm two drive-connecting shaft spacing 1/7 ~ 1/5.
Preferably, load lifting cylinder cylinder barrel and support arm lifting end and pivot joint, piston of load lifting cylinder masthead end and car bottom pivot joint.
The utility model load lifting cylinder, when promoting compartment and rotating, by the support arm that arranges, draws high arm straps and moves load lifting cylinder and also moving towards the direction in convergence compartment, thus load lifting cylinder can be made to promote compartment by short effective travel complete large corner; The utility model vibrational power flow is reasonable simultaneously, avoids the load lifting cylinder problem that load is excessive in initial acting.
