In the city, all can produce a large amount of house refuses every day, and because the urban area is wide, garbage transfer point distribution limit is large, in order to guarantee the instant cleaning of rubbish, needs usually that garbage removing cart transports, centralized recovery rubbish.Self-dumping garbage truck is mainly used in the unified recovery of rubbish, during recovery, opens the back door, by refuse compaction equipment, the rubbish of concentrating is sent into transport box, be transported to landfill yard after collection is full, in collection process, the back door of opening is in directly over refuse compaction equipment, easily interfere with it, cause the collision at refuse compaction equipment and back door, and, when reclaiming rubbish, if the back door is closed because fault falls, easily the dumper is caused personal injury, dangerous property.
China Patent Publication No. CN101628656A, open day on January 20th, 2010, the name of invention is called a kind of carriage back door of compression garbage truck, this application case discloses a kind of carriage back door of compression garbage truck, it comprises a body, door body periphery is provided with frame, the frame rear side is provided with the base plate of sealing, described base plate is by upper flat plate, middle plateform and lower dull and stereotyped three agllutinations close and form, lower plate height is the 1/3-1/2 of frame height, the upper flat plate height is the 1/3-2/5 of frame height, angle between lower flat board and frame front end face is 2 °-6 °, between lower flat board and middle plateform, angle is 174 °-178 °, between middle plateform and upper flat plate, angle is 167 °-171 °.This invention weak point is, rear overhang is opened above refuse compaction equipment in the back door, easily produces interference and has potential safety hazard with refuse compaction equipment.
The utility model content
The back door of garbage truck that the utility model has overcome prior art is easily with the refuse compaction equipment interference and there is the deficiency of potential safety hazard, provides a kind of and can not collide with refuse compaction equipment and the back door on-off structure of safe self-dumping garbage truck.
The utility model is achieved through the following technical solutions:
A kind of back door on-off structure of self-dumping garbage truck, comprise back door, the back door oil cylinder of being located at the transport box rear, described back door is provided with flip-arm, the piston rod of described back door oil cylinder and an end of a pivoted arm are hinged, the other end of described pivoted arm is connected with flip-arm, the end that described pivoted arm is connected with flip-arm is provided with slide shaft, and described transport box is provided with the slide plate with bar hole, and described slide shaft stretches in bar hole and is connected with slide plate slides.When open at the back door, hydraulic efficiency pressure system is to back door oil cylinder fuel feeding, and piston rod stretches out the drive pivoted arm and moves backward, and slide shaft slides into low order end along bar hole, begin to rotate, flip-arm turn to take slide shaft as the center of circle above transport box, and carry out garbage reclamation this moment, and the back door can not touch refuse compaction equipment fully, and because the back door is in transport box top, supported, can not dropped, safe.After garbage reclamation was completed, the back door was returned along former track and is closed.
As preferably, be provided with lower position block above described pivoted arm, described transport box side top is provided with upper limit position block, and the confined planes of described lower position block, upper limit position block is in same perpendicular.During open back door, limiting stopper can be controlled the maximum opening angle at back door, prevents from opening excessively, and during closing back door, the back door is for some time take lower position block as relying on upset to fall, the stability in the time of also improving flip-arm when providing good spacing and initially fall.
As preferably, described flip-arm comprises a horizon bar, and described horizon bar one end is provided with the fork bar that two ends are connected with horizon bar, and the other end of described fork bar is connected with the back door, and described horizon bar is the integral type structure with the fork bar.Horizon bar, fork bar be common consist of " Y " shape connection structure, guarantee enough Joint strenghts.
As preferably, be provided with elastomeric supporting bracket below described flip-arm, be provided with the nylon block that contacts with flip-arm above described supporting bracket.When the back door was closed, downward impact was larger, and elastomeric supporting bracket can provide the actv. buffering.The material of supporting bracket can be selected rubber or other elastomeric materials.During closing back door, in the end tension process, the upset jib slides on nylon block, and the nylon block friction is little, and hardness is higher, is beneficial to slip and not fragile.
As preferably, described slide plate is in the middle part of transport box short transverse, described bar hole level.Make structure distribution more reasonable, and can avoid the interference of movable part.The bar hole level can guarantee that pivoted arm is more stable when mobile.
Therefore, the beneficial effects of the utility model are: (1) has upper limit position block, lower position block, the stability in the time of can effectively controlling back door open angle and back door and initially fall; (2) combination of nylon block and elastomeric supporting bracket is arranged, has buffer capacity strong, the wear-resisting and characteristic flexibly of sliding.
