The utility model provides a special frock of hook-type jack-up coaster protection, includes guard plate and pressure sensor, and the guard plate suit is in the outside of hook-type coaster, connects through hinge means between the guard plate, and the guard plate of head and the tail both ends department passes through connecting device to be connected into the ring, and the inboard contact surface department welding with the hook-type coaster of guard plate has pressure sensor.

In a preferred scheme, the hinge device comprises a supporting plate and a rotating shaft; the backup pad respectively with the outer wall welding of guard plate, through rotation axis interconnect between the backup pad, the backup pad can rotate with the mutual folding and the expansion of control guard plate around the axle center of rotation axis.

In a preferred scheme, the connecting device comprises a connecting plate, a connecting bolt and a butterfly nut; the connecting plates are respectively welded with the protection plates at the head end and the tail end, connecting bolts penetrate through the connecting plates, and butterfly nuts are in threaded connection with the connecting bolts and used for locking and fixing the connecting plates.

In a preferred scheme, the pressure sensor is of a plate type structure, a wireless sensor is arranged inside the pressure sensor, and the wireless sensor can be in wireless connection with the remote mobile device.

This patent can reach following beneficial effect:

1. the tool is convenient to use and easy to fold, store and release, can effectively protect the side plates of the pulley, prevents the side plates of the pulley from deforming and falling off due to long-term unbalanced stress, and prolongs the service life of the pulley;

2. the frock can prevent the opening board landing and the improper opening of coaster, has avoided the safety risk that the heavy object falls from the eminence, has improved the security that coaster lifted by crane work by a wide margin.
