Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 2 to 7, the vehicle of the present embodiment includes: a car 60, a coupler 70, an uncoupling frame 40, and a coupler yoke 50. The coupler 70 is rotatably disposed through the car 60, the coupler 70 includes a hook body 72, and a lock 10, a lock handle 20, and a lock handle 30 disposed on the hook body 72, wherein the lock 10 has a locked state partially protruding from the hook body 72 and an unlocked state located in the hook body 72. The lock handle 20 is rotatably disposed on the hook body 72, and the lock handle 20 cooperates with the vehicle lock 10 to switch the state of the vehicle lock 10. The lock lifting pin 30 is rotatably disposed on the hook body 72 and inserted into the lock handle 20, and the lock lifting pin 30 can rotate synchronously with the lock handle 20. The unhooking frame 40 is rotatably provided on a vehicle compartment 60 of the vehicle. The hook lever 50 is rotatably provided on the carriage 60, and the hook lever 50 pushes the lock latch 30 to rotate through the unhooking frame 40.

By applying the technical scheme of the embodiment, when the unhooking operation is required, the operator rotates the hook lifting rod 50, and the hook lifting rod 50 abuts against the unhooking frame 40 after rotating so as to drive the unhooking frame 40 to rotate. As the hook lever 50 continues to rotate, the unhooking frame 40 will abut against the lock lifting pin 30 after rotating a certain angle to start rotating the lock lifting pin 30. Once the lock lifter 30 is rotated, the lock lifter 20 is driven to rotate, so that the lock 10 is switched from the locked state to the unlocked state, and inter-coupler uncoupling is achieved. In addition, since the coupling lever 50, the uncoupling frame 40, and the lock lifter 30 are independent from each other and have no connection relationship, when the coupler 70 is reversed, the coupling lever 50 and the uncoupling frame 40 do not restrict the position of the lock lifter 30, so that the coupler 70 can be freely rotated, thereby achieving a function of freely reversing the coupler 70.

As shown in fig. 2 to 8, in the present embodiment, the lock lifting pin 30 includes a pin body 31 and a driving handle 32 disposed at an end of the pin body 31, the pin body 31 is inserted into the lock lifting 20, and the unhooking frame 40 cooperates with the driving handle 32 to drive the lock lifting pin 30 to rotate. The driving handle 32 drives the lock lifting pin 30 to rotate, so that the force required by the rotation of the lock lifting pin 30 can be reduced, and the uncoupling of the coupler is easier.

In the present embodiment, the distance between the end of the driving handle 32 remote from the pin body 31 and the axis of the pin body 31 is between 255mm and 260 mm. If the distance is too small, the force required to rotate the lock lifter 30 is still large, and if the distance is too large, two couplers hooked with each other may lose the wrong uncoupling in case the operator accidentally touches the driving handle 32; and the above structure makes the processing cost high.

As shown in fig. 3 to 5, 7 and 9, in the present embodiment, the driving handle 32 includes a first handle segment 321 and a second handle segment 322, an end of the first handle segment 321 away from the second handle segment 322 is connected to the pin body 31, the second handle segment 322 is bent away from the unhooking frame 40, and an obtuse angle is formed between the first handle segment 321 and the second handle segment 322 to form a fitting recess. As the unhooking frame 40 rotates, the protrusion on the unhooking frame 40 starts to gradually slide into the fitting recess by the second handle section 322. When the unhooking frame 40 is rotated continuously, the protrusion is always positioned in the matching recess. The above structure can effectively increase the friction area so that the driving handle 32 is more easily pushed, and the rotation angle of the driving handle 32 is more accurate, thereby effectively realizing unlocking.

As shown in fig. 8, in the present embodiment, the pin body 31 is provided with a stopper groove 314 extending in the circumferential direction thereof, and a portion of the hook body 72 extends into the stopper groove 314 to limit the rotation angle of the lock lifter 30. Specifically, the stopper groove 314 has two groove walls in the longitudinal direction thereof, and when the lock lifter 30 is rotated by a predetermined angle to switch the lock 10 to the unlocked state, the stopper groove 314 can abut against the hook body 72, and the above structure can remind the operator that the coupler has been uncoupled without rotating the hook lifter 50.

As shown in fig. 8, in the present embodiment, the pin body 31 includes a first mounting column section 311, a second mounting column section 312, and a driving section 313 connected between the first mounting column section 311 and the second mounting column section 312, an outer surface of the driving section 313 has a driving plane, the lock handle 20 is provided with a fitting hole adapted to the driving section 313, the driving handle 32 is connected to the first mounting column section 311, and the limiting groove 314 is provided on the first mounting column section 311. The structure is simple and easy to realize.

In this embodiment, the hook body 72 includes a housing and a bolt (not shown) disposed on the housing, the bolt extending into the limit groove 314 of the pin body 31 of the lock lifting pin 30. The structure is simple, the processing is convenient, and the realization is easy.

As shown in fig. 2 and 6, in the present embodiment, the hook lifting lever 50 includes a lever body 51 and a handle 52, and the lever body 51 is in abutting engagement with the unhooking frame 40. The structure facilitates the rotating of the hook lifting rod 50 by operators, reduces the force required for rotating the hook lifting rod 50 and reduces the labor intensity of the operators.

In this embodiment, the hook lifting lever 50 is formed by bending a steel bar. The bail 50 is made of a rigid material to prevent the coupler from becoming entangled when the coupler is rotated, as mentioned in the background of the invention.

As shown in fig. 2 and 6, the vehicle further includes a hook lifting bar base 90. The bail seat 90 is provided on the vehicle body 60 to mount the bail 50, and the above-described structure is simple. Preferably, in this embodiment, the hook lifting rod seat 90 is two at intervals, and the above structure can ensure the stability of the installation of the hook lifting rod 50, and also prevent the hook lifting rod seat 90 from being too large, thereby reducing the production cost.

As shown in fig. 2, in the present embodiment, the hook body 72 includes a large tooth 721 and a small tooth 722, the side of the small tooth 722 far from the large tooth 721 is provided with an interlocking pocket 100, the end of the large tooth 721 is provided with an interlocking socket 110, and the lock lifter 30 is provided on the side of the large tooth 721 far from the small tooth 722.

A fixed coupler is provided in the other car, and an interlock sleeve opening are also provided in the fixed coupler, the interlock sleeve head of the other car extends into the interlock sleeve opening 100 of the own car, and the interlock sleeve head 110 of the own car extends into the interlock sleeve opening of the other car. The structure ensures that the couplers of the two carriages can still be locked together when the carriages are overturned and poured, and the overturning of the carriages cannot be influenced. In order to achieve the above function, if the lock lifter 30 is provided on the side of the small tooth 722 far from the large tooth 721, at least the following three problems occur: 1. the position of the lock lifting pin 30 interferes with the interlocking pocket 100; 2. the lock lifting pin 30 will interfere with the interlock pocket 100 when rotated; 3. the interlock socket of the other car may interfere with the lock lifter 30. Therefore, in order to avoid the above-mentioned problems, the lock lifting pin 30 is provided on the side of the large tooth 721 away from the small tooth 722, so that the above-mentioned three problems can be effectively avoided.

In the present embodiment, since the lock lifter 30 is disposed on the side of the large tooth 721 away from the small tooth 722, the position of the lock lifter 20 is not changed, and thus the length of the first mounting column section 311 needs to be increased in order to enable the lock lifter 30 to be engaged with the lock lifter 20. Specifically, in the present embodiment, the length of the first mounting post segment 311 is between 215mm and 220 mm. If the length is too long, the production cost is high; if the length is too short, the lock lifter pin 30 cannot be engaged with the lock lifter 20 or the engagement effect is poor.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
