Abstract
The utility model relates to a traction frame, in particular to a traction frame capable of preventing a traction pin from falling off. The traction pin is connected with a lifting claw into a whole through an iron chain; and a lifting claw pin is arranged on a bracket of the traction frame to prevent the traction pin from falling off. When a vehicle works normally, the traction pin is clamped by the lifting claw to be prevented from falling off; when the traction pin is required to be pulled out, the iron chain is lifted to drive the lifting claw to rotate by a certain angle, and then the traction pin can be pulled out. The traction frame of the utility model has the benefits that: 1, the traction pin of the engineering machinery vehicle can be prevented from being shocked to fall off so as to strengthen the safety of the whole vehicle; and 2, the traction pin and the traction frame are connected into a whole by the iron chain, so that the traction pin can be quickly inserted and pulled out and can also be prevented from being lost.
Description
Technical field
The utility model relates to a kind of drawbar frame, relates in particular to the drawbar frame that a kind of anti-towing pin comes off.
Background technology
Engineering machinery vehicle often uses drawbar frame to draw article; Because ground is uneven or the vehicle vibrations are bigger; The towing pin of drawbar frame is often deviate from mounting hole, causes towing pin to be lost or the rope of drawing article comes off, even causes personnel's the injures and deaths or the loss of property.
The utility model content
The utility model technical matters to be solved is: the drawbar frame that provides a kind of anti-towing pin to come off, prevent that towing pin is given a shock to come off, and the insertion of Rapid Realization towing pin and extracting guarantees the integraty of engineering machinery vehicle.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is:
The drawbar frame that a kind of anti-towing pin comes off; It comprises drawbar frame 1, towing pin 2, iron chains 3, support 4, sincere pawl 5, bolt 6, nut 7, spring cotter 8, bolt 9, pad 10; Drawbar frame 1 is fixed on the engineering machinery vehicle through bolt 9 and pad 10; Towing pin 2 connects as one through iron chains 3 and sincere pawl 5, and sincere pawl 5 passes through bolt 6, nut 7 and spring cotter 8 pin joints on the support 4 of drawbar frame 1.
The principle of work of the utility model is: during the engineering machinery vehicle normal operation, sincere pawl 5 blocks towing pin 2 and prevents that it from scurrying out and come off; When need are extracted towing pin 2, iron chains 3 is mentioned, turn an angle thereby drive sincere pawl 5, can extract towing pin 2 this moment.
The beneficial effect of the utility model is: can prevent effectively that 1, the engineering machinery vehicle towing pin is come off by shake, has strengthened the safety of car load.2, towing pin and drawbar frame connect as one by iron chains, but the plug of Rapid Realization towing pin also can prevent losing of towing pin.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Wherein, 1-drawbar frame, 2-towing pin, 3-iron chains, 4-support, the sincere pawl of 5-, 6-bolt, 7-nut, 8-spring cotter, 9-bolt, 10-pad.
The specific embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
With reference to accompanying drawing; This specific embodiment does; The drawbar frame that a kind of anti-towing pin comes off, it comprises drawbar frame 1, towing pin 2, iron chains 3, support 4, sincere pawl 5, bolt 6, nut 7, spring cotter 8, bolt 9, pad 10, drawbar frame 1 is fixed on the engineering machinery vehicle through bolt 9 and pad 10; Towing pin 2 connects as one through iron chains 3 and sincere pawl 5, and sincere pawl 5 passes through bolt 6, nut 7 and spring cotter 8 pin joints on the support 4 of drawbar frame 1.
The principle of work of this specific embodiment is: during the engineering machinery vehicle normal operation, sincere pawl 5 blocks towing pin 2 and prevents that it from scurrying out and come off; When need are extracted towing pin 2, iron chains 3 is mentioned, turn an angle thereby drive sincere pawl 5, can extract towing pin 2 this moment.
The beneficial effect of this specific embodiment is: can prevent effectively that 1, the engineering machinery vehicle towing pin is come off by shake, has strengthened the safety of car load.2, towing pin and drawbar frame connect as one by iron chains, but the plug of Rapid Realization towing pin also can prevent losing of towing pin.
