The hook portion of suspension hook is located at that mounting plate is outer and corresponding with the hook portion of mounting plate, and bayonet part is between two mobile articulated slabs and passes through
The mobile articulated shaft of pair is connect with mobile articulated slab, and interconnecting piece is connect by fixed hinge axis with two mounting plates；Main movement is hinged
The end of axis and secondary mobile articulated shaft is located in sliding slot；Safety cock is provided with hook portion and connecting column, the hook portion and active of safety cock
The hook portion of suspension hook hooks, and connecting column is connect after passing through mounting plate with dead-man's handle；Torsion spring is set on connecting column, both ends difference
It is fixed on two mounting plates.
Further, position corresponding with sliding slot is provided with protrusion on the lateral surface of mounting plate.
Further, the first end of power transmission pull rod is rotatablely connected by pin shaft and hanging ring.
Further, main mobile articulated shaft, secondary mobile articulated shaft and fixed hinge axis are the bolt equipped with nut.
Further, dead-man's handle is equipped with decorative pattern.
The beneficial effects of the utility model are:
Hanging ring is connect with boom hoisting (such as crane), rotates dead-man's handle, drives active suspension hook outside by safety cock
It rotates, behind gap of the rail head of rail across structure suspension hook and active suspension hook, dead-man's handle is unclamped, in the elastic force of torsion spring
Lower active suspension hook is acted on to reset, structure suspension hook and active suspension hook are stuck on the web of the rail of rail, during lifting, active suspension hook by
To the gravity of rail, mobile articulated slab is along sliding slot slide downward, due to the restriction effect of fixed hinge axis, active suspension hook
Inwardly rotation cooperates with structure suspension hook and clamps rail.From the foregoing, it will be observed that rail hook gear provided by the utility model can be square
Being mounted on rail just, has preferable chucking power, reduces the risk of unhook, improves hoisting safety.

Specific embodiment
The present embodiment provides a kind of rail hook gears, as shown in Figure 1 to Figure 3, including two mounting plates being oppositely arranged
1, structure suspension hook 2, hanging ring 3, power transmission pull rod 4, mobile articulated slab 5, active suspension hook 6, safety cock 7, dead-man's handle 8 and torsion spring 9；
Mounting plate 1 has curved hook portion, and medial surface is provided with sliding slot 10；Structure suspension hook 2 is column structure, connects two mounting plates 1
Hook portion, for example the through-hole that passes through for structure suspension hook 2 is set in the hook portion of mounting plate 1, structure suspension hook 2 is fastened after passing through；
The first end and hanging ring 3 of power transmission pull rod 4 are rotatablely connected, and second end is located between two mobile articulated slabs 5 and by main mobile hinge
Spindle 11 is connect with mobile articulated slab 5；Active suspension hook 6 includes curved hook portion and bayonet part and connection hook portion and bayonet part
