Technical field
The utility model relates to a kind of tractor truck, particularly a kind of tractor truck automatic hanging unhook system.
Background technology
When utilizing tractor truck to carry out the traction of superimposed trailer, owing to relating to disengaging, coupled condition between superimposed trailer and tractor truck.Traditional method adopts manually carries out, and a people drives tractor truck in operator's compartment, makes its traction saddle near the superimposed trailer front end, is manually worn the latch that is connected superimposed trailer and tractor truck by another people.The shortcoming of this kind method is: chaufeur can't operate alone, needs two people to coordinate just and can carry out, and is very inconvenient; The traction saddle of tractor truck is not easy to aim at the superimposed trailer front end, need to repeatedly adjust the position of tractor truck, connects consuming time.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of the extension and breaks off relations convenient, fast and save artificial tractor truck automatic hanging unhook system.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of tractor truck automatic hanging unhook system, comprise the pulling force support beam that is connected and fixed with the tractor truck frame rear end, its innovative point is: comprise that also one is arranged on the traction saddle on the pulling force support beam, described traction saddle is provided with superimposed trailer and automatically is connected guide frame, have the vertically-guided hole on described traction saddle, in this pilot hole, latch is set; Also be provided with driver train on described tractor truck frame, described driver train can drive latch and vertically stretches under pilot hole guiding or break away from the traction saddle.
Further, described traction saddle superimposed trailer automatically is connected guide frame and is: the traction saddle is opening enlarging shape backward, and the lowermost end of enlarging just can chimeric superimposed trailer propons the top; When described superimposed trailer propons top propped up traction saddle enlarging lowermost end, the pin hole on superimposed trailer propons top alignd with the pilot hole that draws saddle.
Further, described driver train comprises leverage and changed course connecting rod mechanism, leverage comprises a drive link, drive link bearing, joystick and output pipe link, described drive link level is arranged on the drive link bearing, and drive link can freely rotate in the drive link bearing, one end of drive link is connected and fixed with the joystick that is positioned at tractor cab, and the other end is connected and fixed with the output pipe link; Described changed course connecting rod mechanism comprises diverted connection spare, vertically to pipe link and level to pipe link, described diverted connection spare is hinged with the reinforcement connecting element that is fixed on the tractor truck frame, diverted connection spare two ends are respectively hinged vertically to pipe link and level to pipe link, described vertical hinged to the other end and the latch of pipe link, level is hinged to the output pipe link of the pipe link other end and leverage.
Further, between described reinforcement connecting element and pulling force support beam, the support reinforcing part is set.
Principle of work: when needing to connect tractor truck and superimposed trailer, the staff drives the traction saddle of tractor truck near superimposed trailer, superimposed trailer at the traction saddle is connected under the effect of guide frame automatically, make superimposed trailer propons top automatically stretch in the traction saddle and prop up bottom surface, the pin hole that makes the superimposed trailer propons with draw the saddle pilot hole and align; The staff pulls joystick in operator's compartment, pull latch to be passed down through pilot hole and pin hole by the changed course connecting rod mechanism, thereby realizes that tractor truck is connected connection with superimposed trailer.And tractor truck and superimposed trailer need to be broken away from the time, directly by driver train, latch is mentioned and get final product.
The utility model has the advantage of: utilize the superimposed trailer of traction saddle automatically to be connected the guide frame automatic guide, realize the prelocalization that is connected of superimposed trailer and tractor truck; The driver train actuating bar that is positioned at operator's compartment by driver's operation again comes mobile latch, realize being connected of superimposed trailer and tractor truck, easy to operate, quick, only need a people to carry out, save artificial, and under structure function of the present utility model, strengthened pulling force support beam structure intensity, safety, reliability also are largely increased.In the utility model, automatic hanging unhook system adopts tailing, waste material to process, low cost of manufacture.
Description of drawings
Fig. 1 is the utility model tractor truck automatic hanging unhook system architecture schematic diagram.
Fig. 2 is leverage birds-eye view in the utility model.
The specific embodiment
As shown in Figure 1, pulling force support beam 1, traction saddle 2, latch 3, drive link 4, drive link bearing 5, joystick 6, output pipe link 7, diverted connection spare 8, vertically to pipe link 9 and level to pipe link 10.
Above-mentioned pulling force support beam 1 is connected and fixed with tractor truck frame back segment, is fixed with traction saddle 2 at the middle part of pulling force support beam 1, and this traction saddle 2 directly is welded and fixed with the aft end face of pulling force support beam 1.
Traction has vertically-guided hole 21 on saddle 2, and traction saddle 2 is provided with superimposed trailer and automatically is connected guide frame, is specially: traction saddle 2 is opening enlarging shape backward, and the lowermost end of enlarging just can chimeric superimposed trailer propons the unitor end on top.The unitor end on superimposed trailer propons top has the pin shaft hole of vertical direction, and this pin shaft hole aligns with the pilot hole 21 that draws saddle 2 when superimposed trailer propons top props up traction saddle 2 enlarging lowermost end.
