A kind of improved swing arm type self-loading and unloading vehicle
The utility model relates to a kind of self-chambering, self-unloading, transports the transport trolley of function certainly, is specially adapted to the on-the-spot large tank of frequent transhipment, the transport operation of casing of needing of field produces, belongs to the oilfield transportation device.
At present, existing swing arm type self-loading and unloading vehicle is made up of body with frame, subframe, arm, hydraulic efficiency pressure system, several parts of casing, is mainly used in the collection and the transportation of domestic waste.Because the arm of existing swing arm type self-loading and unloading vehicle adopts single working arm structure or adopts straight-arm lift arm and straight-arm swing arm arm structure, and with swing arm as telescopic boom, the working arm height is restricted always, can not be applied to the carrying of oil field with pressure break jar, clear water jar, movable barracks, therefore the carrying of oil field large tank, casing still relies on crane and flat-bed trailer, causes that the oil field equipment handling efficiency is low, cost is high.
Summary of the invention
The purpose of this utility model is exactly the shortcoming that overcomes prior art, and a kind of improved swing arm type self-loading and unloading vehicle is provided.
The purpose of this utility model is achieved in that a kind of improved swing arm type self-loading and unloading vehicle is made up of body with frame, subframe, subframe is fixed on the main girder of body with frame, postmedian at subframe is hinged with flexible lift arm, the other end of flexible lift arm and swing arm oil cylinder and L shaped swing arm are hinged, front end in L shaped swing arm is provided with hook, is hinged near an end of hook and the other end of swing arm oil cylinder in L shaped swing arm; The front portion of subframe is hinged with elevating ram, and the other end of elevating ram is hinged on the bottom of flexible lift arm.
The cross section of flexible lift arm and L shaped swing arm is a railway carriage or compartment shape structure.
Be fixed with locking bail at the subframe middle part, afterbody is equipped with sets upright roller, and hydraulic ram is equipped with in both sides.
The utility model is telescopic boom with the lift arm, and reduced the hinge-point of L shaped swing arm and flexible lift arm, thereby under the situation that guarantees loading and unloading Large Box, the required operating altitude of tank body, reduced in the loading and unloading process certainly requirement as much as possible to the operating altitude of whole working arm, improved the bending strength of arm effectively, do not need to cooperate carrying, the loading and unloading operation that just can finish large tank, casing with other vehicle, handling safety is quick.

The specific embodiment
As shown in Figure 1, a kind of improved swing arm type self-loading and unloading vehicle body with frame 1, subframe 8 is formed, subframe 8 is fixed on the main girder of body with frame 1, flexible lift arm 5 one ends of railway carriage or compartment tee section adopt articulated manner to be fixed on the postmedian of subframe 8, the top of the other end and swing arm oil cylinder 2 are hinged, the top is hinged by the L shaped swing arm of upper/lower positions place and railway carriage or compartment tee section 3, there is not pivotally attached one end to be welded with hook 4 in L shaped swing arm 3, be hinged at an end and the swing arm oil cylinder 2 of L shaped swing arm 3 near hook 4, elevating ram 10 1 ends adopt articulated manner to be fixed on the front portion of subframe 8, the other end is hinged on flexible lift arm 5 lower ends, be fixed with locking bail 9 at subframe 8 middle parts, so that pin vehicle-mounted case, tank body.Subframe 8 afterbodys are equipped with sets upright roller 6, adopts and to set upright the requirement that roller 6 reduces vehicle backing centering, makes car load have normal operation under the situation of certain angle in horizontal surface at case, tank body axis and chassis axis.In the both sides of subframe 8 hydraulic ram 7 is installed, when loading and unloading, hydraulic ram 7 support ground play stable car load.
In conjunction with Fig. 2 the utility model course of action is further described: during loading, operation elevating ram 10 stretches out flexible lift arm 5 backward, operate swing arm oil cylinder 2 simultaneously and drive L shaped swing arm 3, hook 4 is hung with casing to be closed, reclaim elevating ram 10, drive casing and move on car, the flexible lift arm 5 of elongation makes locking bail 9 fastened housings then, promptly finishes loading operation; When unloading, shrink flexible lift arm 5, make casing break away from locking bail 9, operation elevating ram 10 drives flexible lift arm 5 and stretches out, drive the casing hang on the hook 4 simultaneously and move backward, treat that casing all lands after, make hook 4 break away from casings by operation swing arm oil cylinder 2 and promptly finish the operation of getting off.
