Two curb plates hang the bottom plate to two curb plates articulate a set of hanger plate respectively, can stabilize the couple structure, avoid warping, guarantee that the tup is accepted in the locking reliability.

Further preferably, the two side plates on the first hook or the two side plates on the second hook are connected through a reinforcing plate.

Further strengthening the hook structure.

Further preferably, the pushing device is arranged between the side plate of the first hook and the side plate of the second hook.

Preferably, the hanging plates are arranged side by side, every two adjacent hanging plates are arranged at intervals, a groove is formed between every two adjacent hanging plates, and the tops of the first hook and the second hook extend into the groove.

The connecting piece of clamping the hook by the two hanging plates can ensure the hinge reliability and avoid the hook from falling off.

Preferably, the pushing device is an oil cylinder, an electric cylinder or an air cylinder, and two ends of the pushing device are respectively and rotatably connected with the first hook and the second hook.

Compared with the prior art, the utility model discloses the beneficial effect who has is: utilize thrust unit control safety latch hook to open and shut to utilize the meshing tooth to realize the synchronous of two couples and open and shut, realize that two couples form the safety latch hook, can reduce the structural strength of single couple when more safe and reliable, and then can simplify the overall structure of safety latch hook, can set up electromagnetism tamping machine safety latch hook alone to every tup, every tup independent control, the security is better, has improved the availability factor of tamping machine. Two couples are opened and shut through the gear is synchronous, ensure that the angle of opening and shutting of two couples is unanimous, avoid appearing the skew and lead to the couple to obstruct the condition that the tup normally falls, the reliability is higher, long service life.
