It is interior, and the draft gear 1 be internally provided with the safe pull-up space 5 of connection and safe error prevention device 15 to interface 16.It is logical
It crosses trailer wagon connection traction object and by traction object, plays the role of slowing down two articles produced impulse force in traction, make traction
The output of power is gentler, will not be excessive because of impulse force so that destruction is by traction object, and there is idler wheel in trailer wagon lower section so that drawing
Trolley is all more convenient during movement and work.
Referring to Fig. 2, the pulling force liquidate with the side middle part of action plate 111 be provided with pulling force liquidate use annular
Slot 112, the pulling force liquidates to be liquidated in the pulling force with liquidating equipped with pulling force with closed at annular groove 112 with action plate 111
Baffle ring 113, the pulling force liquidates to be connected with the end face of action plate 111 in its center location pulling force transmission connecting rod 12.It is main
It is that input terminal pulling force is conducted to by traction object to act on, while slows down the input speed of input terminal pulling force, makes pulling force and rebound
Power liquidates, and slows down the impulse force generated in distraction procedure.
Referring to Fig. 3, the safety prevents misusing and the safety is provided in babinet 151 prevents misusing safe space 152, it is described
Safety is anti-misuse safe space 152 be close to the anti-one end for misusing docking mouth 154 of safety be provided with the safety prevent misusing every
Board slot 153, the safety, which prevents misusing, docks mouth 153 and being communicated to interface 16 inside draft gear 1, and the safety prevents misusing peace
It is provided with a safety in the total space 152 to prevent misusing displacement bar 155, the safety prevents misusing displacement bar 155 close to safe mistake proofing
One end of septalium 153 is provided with a safety to prevent misusing partition plate 156, the safety is prevented misusing anti-away from safety in babinet 151
It misuses and is provided with that a safety is anti-to misuse feed inlet 157 to one end of interface 154, the safety prevents that it is by linking up to misuse feed inlet 157
The anti-safety for misusing safe space 152 of extraneous and safety prevents that misusing feeding-passage 158 and safety prevents misusing in feeding-passage 158
Safe anti-159 two parts of protective door of misusing form, and prevent that misuse babinet 151 prevents misusing septalium 153 close to safe in the safety
The side of one end is provided with that a safety is anti-to misuse blow vent 1510, and what the safety prevented misusing blow vent 1510 is internally provided with a ditch
Lead to the anti-safety for misusing safe space 152 of extraneous and safety to prevent misusing venthole 1511, the safety prevents misusing the thickness of partition plate 156
Degree prevents that misusing partition plate 156 prevents misusing displacement in safety much larger than the anti-size for misusing 1511 bore of venthole of safety, the safety
When being moved on bar 155, prevent that the part for misusing septalium 153 can leave safety and prevent misusing septalium 153 completely positioned at safety.
During use, by preventing that misusing feed inlet 157 is packed into a large amount of compressible safe materials, makes to prevent misusing safe sky safely safely
Between thrusts are generated in 152 the anti-partition plate 156 of misusing of safety are promoted to misuse septalium 153 into safety is anti-, and ensure that the thrust is less than
The limiting value for the pulling force that can bear by traction object, at work, input tractive force continue to increase, the peace in compressive traction device
Full substance, the thrust that the safe material compressed at this time generates is also increasing, prevents when the thrust in draft gear 1 is more than safety
When misusing thrust caused by the substance in babinet 151, safety prevents that safety will be pushed away under force by misusing partition plate 156
Anti- to misuse septalium 153, such Partial security substance runs past the anti-venthole 1511 of misusing of safety and enters in U-type groove 17, rises
To mistake proofing and warning function, the result being damaged so as to avoid tractive force caused by excessive by traction object.
Specifically used mode：In present invention work, in use, mobile trailer wagon is to drawing object and by among traction object,
By preventing that misusing feed inlet 157 is packed into a large amount of compressible safe materials safely, make to prevent misusing in safe space 152 safely to generate
Thrust promotes the anti-partition plate 156 of misusing of safety to misuse septalium 153 into safety is anti-, and ensures that the thrust is less than by traction object institute energy
The limiting value of pulling force is born, fixed link 4 and the connection of pulling force output rod 13 traction object are inputted and by traction object by pulling force respectively,
During work, traction object is connected and by traction object by trailer wagon, plays and slows down two articles produced punching in traction
The effect of power, the output for making tractive force is gentler, will not be excessive because of impulse force so that destroying by traction object.Meanwhile input traction
Power continues to increase, the safe material in compressive traction device 1, and the thrust that the safe material compressed at this time generates is also increasingly
Greatly, when the thrust in draft gear 1, which is more than safety, prevents misusing thrust caused by the substance in babinet 151, safety is anti-to misuse
Partition plate 156 will pushed away from safety under force to be prevented misusing septalium 153, and such Partial security substance runs past safety
Anti- venthole 1511 of misusing plays mistake proofing and warning function into U-type groove 17, so as to avoid tractive force it is excessive caused by quilt
The result that traction object is damaged.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Profit requirement rather than above description limit, it is intended that all by what is fallen within the meaning and scope of the equivalent requirements of the claims
Variation is included within the present invention.Any reference numeral in claim should not be considered as to the involved claim of limitation.
