Detailed Description

The following explains an embodiment of the present invention with reference to the drawings.

As shown in fig. 1 to 3, the fixing device for the folding coupler of the railway vehicle of the embodiment mainly includes a coupler base 3, a limiting block 2, a pull rod 1, a tension spring 5 and a rotation pin 7. The hook seat 3 is provided with a bottom plate 31 and two hooks 32 fixed on the bottom plate, the tail parts of the limit blocks 2 and the hooks 32 are rotatably connected through rotating pins 7, the head parts of the limit blocks 2 and the pull rod 1 are connected through limit columns 21 fixed at the bottoms of the limit blocks 2, the head sizes of the limit columns 21 are larger than the sizes of the neck parts of the limit columns, the pull rod 1 is provided with a pull rod long circular hole 11 through which the neck parts of the limit columns 21 pass, and the hook seat 3 is provided with a hook seat long circular hole 33 for accommodating the head parts of the limit. The head of the limiting block 2 is provided with a recess 22, when the head of the limiting block 2 is lifted, the recess 22 and the hook heads of the two hooks 32 form a space for accommodating and limiting a hook fixing rod 8 (the hook fixing rod 8 is fixed at the bottom of a hook 4), and two ends of the tension spring 5 are respectively connected with the hook seat 3 and the pull rod 1 and used for pulling the pull rod 1, so that the pull rod 1 pushes the limiting block 2 through the limiting column 21 to lift the head of the limiting block 2. The hanger base 3 is fixed on a bumper beam of a vehicle through a cushioning amount mounting plate 6.

In this example, a protrusion 12 is provided on the upper surface of the pull rod 1, and a positioning pin 34 for limiting the protrusion 12 is fixed to the hook base 3. The two ends of the tension spring 5 respectively hook the rotating pin 7 and the pin arranged on the convex block 12.

During assembly, the long circular hole of the pull rod and the limiting column are installed on the hook seat together, the rotating pin is screwed in to fix the limiting block, the spring is installed to generate pretension force to tension the pull rod, and finally the positioning pin is installed to limit the vertical positioning of the pull rod.

When the coupler is fixed, the coupler is only required to be rotated, the spring pretensioning force is overcome by slope pressing of the coupler fixing rod limiting block, the effect on the limiting block is released after the coupler fixing rod enters the hook, and the limiting block receives the pretensioning force of the tension spring and automatically bounces and limits and fixes the coupler fixing rod. Does not need any tool and can be operated by a single person. Because the pull rod is tensioned by the spring and pushed towards the direction of the hook, the head of the limiting block keeps a lifting state, the hook fixing rod is limited to be separated from the hook, and the hook fixing rod is limited, so that the hook is fixed.

When the coupler is released, the pulling rod is pulled to overcome the pretension force of the spring, so that the limiting column is pulled, the limiting block can only rotate around the rotating pin due to the limitation of the rotating pin, the limiting block falls into the coupler seat, the coupler fixing device is unlocked, the coupler fixing rod is released, and then the coupler is fixed through releasing.

The fixing device for the folding coupler is particularly suitable for being applied to railway vehicles.

In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
