One leg mechanism is respectively arranged about the support leg device that adopts usually at present.Each leg mechanism has a horizontal telescopic hydraulic cylinder and horizontal support legs, vertical support hydraulic actuating cylinder and vertical leg.It is overhanging together that horizontal telescopic hydraulic cylinder drives horizontal support legs drive vertical leg during lifting operation, shrinks when travelling; Vertical support Driven by Hydraulic Cylinder vertical leg supports vehicle body, shrinks when travelling.During expansion, horizontal support legs and vertical leg are formed the H type.When being used for superimposed trailer, because the semi-trailer direction changing angle is bigger, the vertical component after supporting leg is regained still can interfere with the superimposed trailer car body.
The utility model content
The utility model is in order to overcome weak point of the prior art, provide a kind of employing rope traction to assist folding and unfolding, can be with the mode folding and unfolding supporting leg of side, vertical half-twist, after being regained, supporting leg is positioned at the side of vehicle frame, when avoiding turning to and the support leg device that interferes of superimposed trailer car body.
The utility model is achieved through the following technical solutions:
A kind of steel rope is assisted the folding and unfolding support leg device, it is characterized in that, comprise that the folding and unfolding that is installed on the vehicle body both sides props up leg mechanism, each folding and unfolding is propped up leg mechanism and is comprised pivoted arm, telescopic drive mechanism, the plinth plate, haulage cable, described pivoted arm is rotatably connected by turning cylinder and vehicle body side, the corresponding position of described pivoted arm and vehicle body side is respectively arranged with the horizontal location hole, manually locating dowel pin inserts in two cooresponding horizontal location holes, described telescopic drive mechanism captives joint with pivoted arm, described haulage cable one end is connected with the extension wire rope hole of vehicle body side, the other end is connected with hook on the described telescopic drive mechanism expansion link, described expansion link end is provided with bulb, described plinth plate is placed on the strong point, described plinth plate is provided with and the corresponding ball cap of described bulb, and described pivoted arm closes at the side of vehicle frame along the bodywork length direction when vehicle '.
Described telescopic drive mechanism is a hydraulic actuating cylinder, and expansion link is the piston rod of hydraulic actuating cylinder.
The utlity model has following technique effect:
The auxiliary folding and unfolding support leg device of steel rope of the present utility model adopts rope traction, mode folding and unfolding supporting leg with side, vertical half-twist, guaranteed tractor truck single-piece stability under arbitrary operating mode, simultaneously, because pivoted arm is positioned at the side of vehicle frame along the bodywork length direction when vehicle ', can prevent that supporting leg and tractor truck interfere when turning to.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The scheme drawing of the auxiliary folding and unfolding support leg device horizontality of the utility model steel rope as shown in Figure 1, comprise that the folding and unfolding that is installed on the vehicle body both sides props up leg mechanism, each folding and unfolding is propped up leg mechanism and is comprised pivoted arm 7, telescopic drive mechanism 8, plinth plate 11, haulage cable 4, pivoted arm 7 is rotatably connected by turning cylinder 6 and vehicle body 2 sides, pivoted arm 7 is respectively arranged with the horizontal location hole with the corresponding position of vehicle body side, manually locating dowel pin 1 inserts in two cooresponding horizontal location holes, realizes the horizontal location between pivoted arm and the vehicle body.Described telescopic drive mechanism 8 captives joint with pivoted arm 7.Haulage cable 4 one ends are connected with the extension wire rope hole 3 of vehicle body side, and the hook 5 on the expansion link 9 of the other end and telescopic drive mechanism is connected, and expansion link 9 ends are provided with bulb 10.Plinth plate 11 is placed on strong point place, and plinth plate 11 is provided with and described bulb 10 corresponding ball caps.Described pivoted arm closes at the side of vehicle frame along the bodywork length direction when vehicle '.
Vehicle body is the car body part of superimposed trailer, and being mainly used in provides a stabilised platform.Pivoted arm is the major part that connects hydraulic actuating cylinder or oil cylinder and vehicle frame, for pack up, stretching routine provides a centre of gration, and picking-up hydraulic actuating cylinder or oil cylinder rotate together.Hydraulic actuating cylinder is the vitals of the auxiliary folding and unfolding support leg device of the utility model steel rope, is the main operating unit of retractable operation, is retractable operation, the main confession power source of stablize car body.Hydraulic actuating cylinder is that main type of attachment is fixed on the pivoted arm with bolt.Haulage cable is a key stressed member of realizing packing up supporting leg.Because support leg device weight of the present utility model surpasses 400kg, the individual can't finish the whole process of packing up, and in order to guarantee tractor truck single-piece stability under arbitrary operating mode, prevents when turning to and tractor truck interferes, adopt rope traction, pack up in the mode of side, vertical half-twist.
During expansion, get the strong point place that two plinth plates are placed on the left and right sides respectively, haulage cable one end that each folding and unfolding is propped up in the leg mechanism is connected with the extension wire rope hole 3 of vehicle body side, the other end hangs on the hook, the hydraulic actuating cylinder horizontal direction is stretched out fully, the tensioning haulage cable, as shown in Figure 1.Extract the manual locating dowel pin in the horizontal location hole, pivoted arm can be rotated, stretch on operating hydraulically operated cylinder top, under the effect of deadweight and haulage cable, it is that axle rotates together with the rotating shaft that pivoted arm holds up hydraulic actuating cylinder, as shown in Figure 2, until perpendicular to the ground, as shown in Figure 3, regain then hydraulic actuating cylinder to haulage cable pausing operation when loosening, and haulage cable got loose from hook, the plinth plate be placed on bulb on the hydraulic cylinder piston rod under after, stretch on operating hydraulically operated cylinder top, makes bulb fall in the ball cap of plinth plate and block, as shown in Figure 4.At this moment, propping up leg mechanism by two folding and unfoldings supports car body.
The withdrawal process is opposite with the evolutionary operation process.
Although the disclosed auxiliary folding and unfolding support leg device of a kind of steel rope that relates to has been carried out special description with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
