[0001] The invention relates to the field of rudder stock hoisting, in particular to a rudder stock hoisting tool. Background Art

[0002] The rudder stock is the axis of rotation of the rudder blade. It is used to bear and transmit the force acting on the rudder blade and the force applied by the rudder to the steering device. In other words, the steering gear rotates the rudder blade through the rudder stock, and the rudder blade bears the reaction force of the water to turn the ship. Because the rudder stock is the component that bears the torque and bending moment caused by the rudder pressure, it is relatively heavy and requires a lifting device to move the rudder stock. The existing rudder stock lifting device is often unable to quickly fix the rudder stock to the lifting device during use. The fixing of the rudder stock is time-consuming and labor-intensive, and the moving process is not stable. Therefore, it is necessary to design a rudder stock lifting device that is easy to use.

[0033] Working principle of the present invention:

[0034] When in use, the push rod 801 is pushed along the slide groove by manpower, and the end of the push rod 801 in contact with the elastic spring 803 will rotate clockwise through the support block 802. The push rod 801 will cause the movable rod 804 to rotate during the movement. The movement of the movable rod 804 will cause the matching block 704 to move toward the side close to the elastic spring 803 and drive the square plate 702 to move to the same side. The movement of the square plate 702 will cause the positioning block 701 to move out of the inside of the positioning groove 9, so that the connecting plate 2 can be separated from the rudder stock 1. The push rod 801 will be in a state of rotation during the movement. During the movement, the elastic spring 803 will generate a deformation force. After the push rod 801 is released, the elastic spring 803 will give the push rod 801 the same force, so that the push rod 801 drives the movable rod 804 to rebound to its original position. The square plate 702 will generate a deformation force during the movement. When the push rod 801 is released, the tension spring 703 will give the square plate 702 the same force, so that the square plate 702 drives the matching block 704 and the positioning block 701 rebounds to the inside of the positioning groove 9, thereby achieving the fixation of the connecting plate 2 and the rudder stock 1.

[0035] To sum up: the rudder stock lifting fixture is achieved by symmetrically arranging four lifting fixtures 3 on the connecting plate 2, and the lifting fixture 3 includes a limiting column 4 and a fixing block 5 that cooperates with the limiting column 4; by arranging a positioning device 7 and a pushing device 8 in the groove 6 of the fixing block 5, the positioning block 701, the square plate 702, the tension spring 703, the matching block 704, the pushing device 8, the push rod 801, the support block 802, the elastic spring 803, the movable rod 804, the positioning groove 9, the sliding hole 10 and the L-shaped block 11 are used in coordination, so that the rudder stock can be quickly fixed to the lifting during use, thereby improving the efficiency of lifting and fixing, and at the same time improving the stability of the moving process.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
