Fig. 2 is the structural representation of Gooseneck-type semitrailer of the present invention,
Fig. 3 is the structural representation of Gooseneck-type semitrailer of the present invention, the structural representation when this gooseneck portion shown in the figure launches with the facial formation of carrying continuous level.
The specific embodiment
Referring to Fig. 2, Gooseneck-type semitrailer of the present invention comprises gooseneck portion 11, suspension installation portion 12, carries face 13 and running part 15; Wherein, Said gooseneck portion 11 is positioned at the front portion of said Gooseneck-type semitrailer; Suspension installation portion 12 is positioned at the rear portion of said Gooseneck-type semitrailer; Said carrying facial 13 links to each other with said suspension installation portion 12 with gooseneck portion 11 between said gooseneck portion 11 and said suspension installation portion 12 and respectively, and said running part 15 is positioned at the below of suspension installation portion 12.When using this Gooseneck-type semitrailer transportation large-scale engineering machinery, usually provide tractor truck to link to each other with gooseneck portion 11 to Gooseneck-type semitrailer, under the dynamic action of tractor truck, this Gooseneck-type semitrailer is realized carrying cargo.
This gooseneck portion 11 comprises tractive unit 111 and connecting portion 112; Wherein, this tractive unit 111 is in order to linking to each other with tractor truck, and then the motion of traction Gooseneck-type semitrailer; Connecting portion 112 is carrying between face 13 and the tractive unit 111 and is linking to each other with carrying facial 13 with tractive unit 111 respectively.
One end of said connecting portion 112 can be articulated in the rear end of said tractive unit 111 through the two first detachable rotating shafts 114,115 with locating, and certainly, this first rotating shaft number also can be set to many; When removing one first rotating shaft 114, drawbar frame 111 can rotate around this root first rotating shaft 115; The other end of said link span 112 can be hinged through the two second detachable rotating shafts 117,118 with facial 13 front ends of carrying with locating, and this second rotating shaft number also can be set to many; When removing one second rotating shaft 117, this link span 112 can rotate around remaining one second rotating shaft 118 of this root.
Also be set with at two said first rotating shafts 114, fixed link 116 between 115 near the position of itself and connecting portion 112 junctions at said tractive unit 111.
The Gooseneck-type semitrailer actuating device 14 among the present invention and the control setup of this actuating device of control; Under the effect of this actuating device 14, these gooseneck portion 11 deployable upper surface of said tractive unit 111 and connecting portion and upper surfaces that carry facial 13 of making form continuous level; And an end of this continuous level contacts with ground; When handling goods 2, this goods 2 can move to carrying facial 13 places along the end that this continuous level contacts with ground; Simultaneously, under the effect of this actuating device 14, also can make continuous level return to the gooseneck shape.
This actuating device 14 comprises telescopic support device 141 and flexible draw off gear 142, and wherein, these telescopic support device 141 1 ends are hinged with the fixed link 116 that is positioned at tractive unit 111 and connecting portion 112 junctions; Its other end vertical support on the ground; Should also be hinged with fixed link 116 by flexible draw off gear 142 1 ends, the other end is hinged with second rotating shaft 118 of carrying facial 113 junctions with being positioned at connecting portion 112, and this end also can be connected second rotating shaft, 117 places certainly.
This telescopic support device 141 comprises hydraulic actuating cylinder and the piston rod that links to each other with hydraulic actuating cylinder and hydraulic actuating cylinder is done fore and aft motion in cylinder pressure effect lower edge; When telescopic support device 141 when supporting Gooseneck-type semitrailer, Driven by Hydraulic Cylinder piston rod direction earthward vertically stretches out; When piston rod contacts with ground, but this Gooseneck-type semitrailer of its effective support; Obviously, this hydraulic actuating cylinder also can adopt air cylinder to substitute, and like this, can reach same technique effect.
The structure of being somebody's turn to do flexible draw off gear 142 is identical with the structure of said telescopic support device 141, and it also comprises hydraulic actuating cylinder and the piston rod that links to each other with hydraulic actuating cylinder and hydraulic actuating cylinder is done fore and aft motion in cylinder pressure effect lower edge; Certainly, this hydraulic actuating cylinder also can adopt air cylinder to substitute.
This control setup is electrical control composite sets such as PLC, travel switch, computing machine.
Referring to Fig. 3; When Gooseneck-type semitrailer loading and unloading large cargo; When needing to launch gooseneck portion 11 with vehicle main body 13 formation continuous levels, at first remove first rotating shaft 114 from tractive unit 11 and connecting portion 112 junctions, flexible draw off gear 142 is launched; Should stretch draw off gear 142 in expansion process; It promotes tractive unit 11 through coupled anchor shaft 116 is that the center clockwise rotates (plane, figure place that provides with Fig. 2 and Fig. 3 is a plane of reference) with first rotating shaft 115, and when it turned to connecting portion 112 equal angular positions, this tractive unit 11 was positioned on the identical inclined-plane with these connecting portion 112 upper surfaces; Remove from connecting portion 112 second rotating shaft 117 with carrying facial 13 junctions then, telescopic support device 141 is shunk, in telescopic support device 141 contraction processes; This tractive unit 11 and connecting portion 112 by gravitys; With second rotating shaft 118 is the center conter clockwise to rotating near the ground direction, when tractive unit 11 1 ends lean when locate on ground the upper surface of this tractive unit 11 and connecting portion 112 and the upper surface formation continuous level that carries facial 13; This continuous level and ground-surface angle are smaller; Heavy construction mechanism climbs to more easily and carries on the face, saves time, laborsaving, very convenient.Overcome existing Gooseneck-type semitrailer owing to reasons in structure, cat ladder and ground angle are big, are unfavorable for the shortcoming of handling goods 2.
In conjunction with reference to figure 2, when the completed loading goods, when needing continuous level retraction formation gooseneck shape; Telescopic support device 141 is launched; In telescopic support device 141 stretching process, this tractive unit 11 and connecting portion 112 are that the center clockwise direction is rotated away from the ground direction along second rotating shaft 118 under the thrust of telescopic support device 141; When it rotates to its original position angle of living in, be positioned at original position to second rotating shaft 117 of removing; At this moment, the connecting portion 112 relative faces 13 that carry are able to fix; Then, flexible draw off gear 142 is shunk; Should stretch draw off gear 142 in contraction process; Pulling tractive unit 11 is that the center rotates counterclockwise with first rotating shaft 115; When it rotates to its original position angle of living in, be positioned at original position to first rotating shaft 114 of removing, at this moment; Tractive unit 11 relative these connecting portions 112 are able to fix, thereby make the continuous level retraction form the gooseneck shape.
In order to make telescopic support device 141 edges and ground vertical basically stretching, extension or contraction; Between these telescopic support device 141 bottoms and the facial 13 front end bottom surfaces of carrying, be hinged with pilot bar 143; Under the guide function of this pilot bar 143; Telescopic support device 141 is in motion process, and these telescopic support device 141 maintenances are vertical basically with ground; It also plays fixation to bracing or strutting arrangement 141 simultaneously.When tractor truck with after this trailer is connected, bracing or strutting arrangement 141 needs further to shrink, and with ground certain distance is arranged, 141 fixations of 143 pairs of bracing or strutting arrangements of pilot bar this moment prevent that in vehicle operating bracing or strutting arrangement 141 swings back and forth.
