The utility model content
The purpose of the utility model just provides a kind of employing machinery and handles, and is easy to use, and back springboard is directly installed on the transport trolley, can according to condition of service adjustment back springboard mode of operation the time commercial transport superimposed trailer that puts down back lifting mechanism.
The solution of the utility model is such: include two symmetrical rotating springboards, be used to carry the commercial vehicle/comm..vehicle wheel and go, point is articulated and connected with the back frame lug before the described springboard, is connected with the triangle arm on the springboard; Described triangle arm and oil cylinder piston bar are hinged, make the swing arm structure of the flexible drive triangle arm rotation that constitutes the oil cylinder piston bar between springboard, triangle arm and the oil cylinder piston bar.
According to such scheme, the utility model can have following two kinds of concrete enforcement structures:
The structure of lifting when 1, stretch on oil cylinder top, this kind structure, described springboard be connected with the triangle arm be left and right sides springboard the bottom respectively with about two symmetrically arranged triangle arms be welded to connect; Described swing arm structure be meant before the triangle arm point and oil cylinder piston bar be articulated and connected with springboard before point and the hinged swinging structure that constitutes of back frame lug, the oil cylinder piston bar be promote with the springboard welding after the triangle arm drive upwards swing of springboard.
2, the structure of oil cylinder when retraction top lifting, this kind structure, described springboard be connected with the triangle arm be springboard and respectively with about the short rod of two symmetric arrangement be articulated and connected point articulated connection the behind short rod and the triangle arm; Described swing arm structure be meant on the triangle arm point and oil cylinder piston bar be articulated and connected with the triangle arm before the hinged swinging structure that constitutes of supporting seat on point and the back vehicle frame, the oil cylinder piston bar is that pulling drives upwards swing of springboard with springboard bonded assembly triangle arm.
Be hinged with the long draw back segment at said springboard, back vehicle frame is hinged with the long draw leading portion, and in fortune turner condition, said long draw back segment and long draw leading portion are connected to integral body with connecting pin.
Said long draw back segment and long draw leading portion junction are provided with pull bar interlude connecting panel, and described connecting pin is to be connected with the long draw back segment or to be connected with the long draw leading portion.
The utility model has the advantages that and adopt the mode of mechanical control to operate, just can carry out lifting or the whereabouts of springboard or stop in the desired position at operator's station, easy to use, safe and reliable.
Description of drawings
Accompanying drawing is the embodiment of the utility model.
Accompanying drawing 1 is embodiment one structural representation that the utility model oil cylinder pushes up lifting when stretching.
Embodiment two structural representations of lifting when accompanying drawing 2 is the utility model oil cylinder retraction.
Accompanying drawing 3 is the utility model and the scheme drawing that is connected of vehicle frame afterbody 10.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
The utility model overall design thinking is: include two symmetrical rotating springboards, be used to carry the commercial vehicle/comm..vehicle wheel and go, point is articulated and connected with the back frame lug before the described springboard, is connected with the triangle arm on the springboard; Described triangle arm and oil cylinder piston bar are hinged, make the swing arm structure of the flexible drive triangle arm rotation that constitutes the oil cylinder piston bar between springboard, triangle arm and the oil cylinder piston bar.
According to above-mentioned thinking, the embodiment of the utility model has:
Embodiment one: shown in accompanying drawing 1, the utility model includes rotating springboard 6, and described springboard 6 is hinged with long draw back segment 5, and long draw back segment 5 is connected through pin 3 with long draw leading portion 2, and long draw leading portion 2 is hinged with the vehicle frame aft mount.Springboard 6 and 4 welding of triangle arm, point is hinged with the piston rod of oil cylinder 1 before the triangle arm, and the bearing of the base of oil cylinder 1 and vehicle frame afterbody is hinged.The bearing 8 of the rear portion of springboard 6 and vehicle frame afterbody is hinged, and present embodiment is that the oil cylinder piston bar is the structure that the triangle arm drive springboard after promotion is welded with springboard is upwards swung.
Embodiment two: shown in accompanying drawing 2; The utility model includes rotating springboard 6; Described springboard 6 is hinged with long draw back segment 5; Long draw back segment 5 is connected through pin 3 with middle connecting plate 7, and middle connecting plate is connected with long draw leading portion 2 through pin, and long draw 2 is hinged with the vehicle frame aft mount.The middle part of springboard 6 and short rod 9 following point articulated, short rod 9 go up the back point articulated of point and triangle arm 4, the piston rod head of going up point and oil cylinder 1 of triangle arm 4 is hinged, the following point of triangle arm and the bearing 8 of vehicle frame afterbody are hinged.The bearing 8 of the rear portion of springboard 6 and vehicle frame afterbody is hinged, and present embodiment is that the oil cylinder piston bar is that pulling drives the upwards structure of swing of springboard with springboard bonded assembly triangle arm.
The utility model is divided into three kinds of operating modes when using, and describes respectively below:
1, entrucking operating mode: throw off earlier the leading portion 2 and back segment 2 of long draw, handle oil cylinder then and eject or bounce back, springboard 6 is turned to minimum, an end of springboard 6 contacts with ground, and commercial vehicle/comm..vehicle can be opened the transport trolley of getting on the bus along springboard.
2, commercial vehicle/comm..vehicle transportation operating mode: handle oil cylinder, springboard 6 is turned to midway location, long draw back segment 5 and long draw leading portion 2 usefulness are connected to become integral body, springboard 6 is fixing.
Empty wagons operating mode: confirm that earlier long draw leading portion 2 separates with long draw back segment 5, handle oil cylinder 1 then, springboard 6 is turned to vertical position.
