[0008] A column bracket is provided, wherein a crossbeam is fixedly provided on the column bracket, a clamping plate is fixedly provided on the crossbeam, and a rail pulley is slidably installed on the crossbeam.

[0009] The utility model is further configured as follows: the crossbeam is fixedly connected to the turret seat ring through a splint.

[0010] The utility model is further configured as follows: a water jet propulsion device is provided below the crossbeam.

[0011] By adopting the above technical solution, the position of the water jet propulsion device is limited.

[0012] The utility model is further configured as follows: a pulley ring is fixedly provided on the rail pulley.

[0013] The present invention is further configured as follows: the crossbeam is an I-shaped structure.

[0014] By adopting the above technical solution, the shape of the beam is limited.

[0015] The utility model is further configured as follows: a water jet propeller lifting ring is fixedly provided on the water jet propeller.

[0016] The beneficial effects of the utility model are:

[0017] The utility model installs a column bracket above the rear end of the water jet propeller, installs one end of a crossbeam on the column bracket, fixes the other end of the crossbeam on the turret seat ring with a splint, installs a rail pulley on the crossbeam, connects one end of two hand chain hoists to the pulley lifting ring, and connects the other end to the water jet propeller lifting ring. After the water jet propeller is lifted by the hand chain hoist, the whole is slid to the bottom of the turret seat ring, and then the water jet propeller is lifted out by means of a workshop crane, so that the water jet propeller can be vertically lifted.
