[0035] Example 2

[0036] Figure 1 , 2 The figure shows a trackless, tooling-integrated stern work platform, which shares one main platform 1 and one common tooling 3, and the main platform 1 is equipped with four travel mechanisms 2. When installing the propeller 5, the common tooling 3 is fixedly connected to the main platform 1, and then the propeller 5 is placed on the common tooling 3. Then the main platform 1 is driven to drive along the left and right directions into the area between the rudder arm and the propeller bracket, and then each wheel of the travel mechanism 2 is rotated 90°, and then the main platform 1 is driven along the bow and stern directions to drive the propeller close to the propeller bracket, so as to start installing the propeller.

[0037] After the propeller is installed, each wheel of the traveling mechanism 2 is rotated back to 0°, and then the main platform 1 is driven to move out of the propeller installation area in the left and right directions, and finally to the front of the dock wall to prepare for the installation of the rudder blade. The rudder blade 6 is placed in the hanging basket 4, and then the hanging basket 4 is placed on the common tooling 3, and then the main platform 1 is driven to move the rudder blade close to the rudder arm in the bow and stern directions, so as to start installing the rudder blade.

[0038] The entire installation process does not require laying ground rails, dismantling or replacing tooling, or burning any hanging tags.

[0039] Figure 3 The main platform 1 is shown as being used to bear weight and is welded from steel sections. It has the characteristics of high strength and good rigidity, and is stress-relieved after welding.

[0040] Figure 4The traveling mechanism 2 is shown, which is composed of two sets of hydraulic motors 19 (symmetrically arranged on the left and right), one set of traveling reducer 10, one set of traveling rubber wheels 18, one set of steering hydraulic motor 7, one set of steering reduction worm 8, one set of steering reduction turbine 9, and one set of steering encoder 17, to realize traveling drive and steering adjustment. The traveling reducer 10 is provided with a brake.

The displacement in the up-down direction is achieved by the synchronous lifting of four sets of jacking cylinders; the displacement in the horizontal direction (fore and stern, left and right) is achieved by the synchronous transverse movement of two sets of transverse movement mechanisms 14 and the synchronous adjustment of two sets of support point spacing adjustment mechanisms 15; the rotation in the up-down direction is achieved by the reverse transverse movement of two sets of transverse movement mechanisms 14; the rotation in the fore-stern direction is achieved by the height difference of the left and right jacking cylinders 11; the rotation in the left and right direction is achieved by the height difference of the jacking cylinders 11 on the same side.

[0042] The lateral movement mechanism 14 is composed of a lateral movement bracket, a linear guide rail and a slider, a rolling screw and a nut, a precision reducer and a servo motor, etc., which are respectively installed on the jacking cylinder to achieve fine lateral adjustment of the rudder and the propeller. The lateral movement bracket is connected to the jacking cylinder and moves up and down with the jacking cylinder. The linear guide rail and the slider are installed on the lateral movement bracket as a guide for lateral movement and bear the load weight. At the same time, the servo motor, the precision reducer, and the ball screw are also installed on the lateral movement bracket to achieve precise lateral adjustment of the rudder and the propeller.

[0043] The nut locking mechanism 13 is mainly composed of a screw and a nut, and is installed on the lateral movement mechanism. When the rudder and propeller are installed and adjusted, they still need to be supported by the lifting cylinder to assist the lifting cylinder. During operation, the screw is used to support the load, and the nut is used to lock the screw, and the load weight is transferred to the bearing structure through the nut. The screw adopts a T-shaped thread with self-locking performance, and the nut adopts an open and close nut for easy operation.

[0044] The support point spacing adjustment mechanism 15 consists of a set of moving platforms, a set of push-pull cylinders and a set of static platforms. The moving platform is installed and fixedly connected to the lifting cylinder. There is rolling friction contact between the moving platform and the static platform and the lateral rollers are used as guides. The push-pull cylinders are used to drive the moving platform to move between the moving platform and the static platform, thereby realizing the adjustment of the spacing between the rudder propeller support points.

[0045] Figure 6 The basket 4 is shown as a hanging basket, which is used to bear the weight of the rudder blade and is installed on the rudder and oar bracket. It is welded from steel sections and has the characteristics of high strength and good rigidity. After welding, stress relief treatment is performed. Four lateral support cylinders 16 are installed on the rudder blade supporting hanging basket to fix the rudder blade position and adjust the lateral angle of the rudder blade.

[0046] The advantages of the utility model are as follows:

[0047] 1. A set of main platform carrying tooling, the main platform is equipped with four rubber wheels, and can be continuously and automatically turned within the range of ±90°, so there is no need to lay guide rails on the bottom of the dock. The transfer direction of the rudder blades and propellers can be adjusted at will, which improves the transfer efficiency.

[0048] 2. Four sets of lifting cylinders, two sets of lateral movement mechanisms, two sets of cylinder locking mechanisms and two sets of support point spacing adjustment mechanisms are used to form a tooling that can be used for both propellers and rudder blades. When installing the rudder blades, you only need to put the rudder blades into a special hanging basket, and then install the hanging basket on the tooling to start installing the rudder blades. This not only improves efficiency but also reduces the number of steel structures, achieving cost reduction and efficiency improvement.
