DETAILED DESCRIPTION

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0019] like Figure 1 As shown, the split adjustable stern shaft mounting trolley includes a body 1, an adjusting body 2 and a supporting body 3. Four small wheels 101 are provided at the four corners of the bottom of the body. Four first blocks 102 are provided on the top of the body 1. The four blocks 102 are distributed in a rectangular shape. The adjusting body 2 is arranged between the four first blocks 102 on the top of the body 1. Second blocks 201 are provided at the four corners of the adjusting body 2. The four first blocks 102 are all provided with a first through hole. A first bolt top screw 103 is installed in the first through hole. The first bolt top screw 103 abuts against the second block. The adjustment can be adjusted by adjusting the first bolt top screw 103. The joint body 2 is positioned in the length direction of the vehicle body 1, and a support body 3 is provided on the adjusting body 2. The support body 3 is fixed on the base 304. Second through holes are respectively provided on the four corners of the base 304. Second bolt top screws 301 are installed in the second through holes. The second bolt top screws 301 abut against the adjusting body 2. By adjusting the second bolt top screws 301, the height of the support body 3 can be changed; the upper surface of the support body 3 is a concave arc shape, and the arc shape is adapted to the shape of the lower surface of the stern shaft 6. The tangent direction of the arc shape is the same as the length direction of the vehicle body 1, and the moving direction of the vehicle body 1 is the same as the width direction of the vehicle body 1.

[0020] Example 1

[0021] The present invention discloses a split type adjustable stern shaft mounting trolley, comprising a vehicle body 1, an adjusting body 2 and a supporting body 3, as follows Figure 1 As shown in the figure, the vehicle body 1 is equipped with four small wheels and travels on two parallel tracks, with four jackscrews installed on its left and right sides. The adjustment body 2 is located on the vehicle body 1, with four baffles installed on its left and right sides for use with the four jackscrews on the vehicle body 1. The support body 3 is located on the adjustment body 2, with four vertical jackscrews installed at its four corners. The upper portion of the support body 3 is semicircular and matches the surface of the stern shaft. This trolley can be used for towing and installing large shafts. Its features include flexible movement, easy adjustment, and simple disassembly, which can effectively improve installation efficiency and save installation time and costs.

[0022] like Figure 2 As shown, the present invention provides a detachable stern shaft mounting trolley, which consists of three parts: a vehicle body 1, an adjustment body 2 and a support body 3.

[0023] like Figure 3As shown, the vehicle body 1 is partially equipped with four small wheels 101, which travel on two parallel horizontal tracks 5 fixed to the mounting platform 4. Two first blocks 102 are welded to the left and right sides of the vehicle body 1, and each first block 102 is installed with a high-strength first bolt jackscrew 103. The adjustment body 2 is located on the vehicle body 1, and two second blocks 201 are welded to the left and right sides. They are used in conjunction with the four first bolt jackscrews 103 on the vehicle body 1 to adjust the left and right position of the stern shaft 6. The support body 3 is above the adjustment body 2, and its four corners are equipped with four high-strength second bolt jackscrews 301 in the vertical direction for adjusting the vertical position of the stern shaft 6. The upper portion of the support body 3 is arc-shaped, with the arc radius slightly larger than the stern shaft radius. Three cork boards 302 are evenly installed on the arc, and the cork boards are padded with thick rubber 303 to prevent the surface of the support body 3 from hard contact with the surface of the stern shaft 6.

[0024] When in use, the stern shaft 6 is hoisted onto several trolleys, and the stern shaft 6 is adjusted up and down and left and right by turning the first bolt screw 103 and the second bolt screw 301 on the trolley so that the axis coincides with the ship installation axis. Then, the trolley is dragged by external force to move and the stern shaft 6 is slowly inserted into the stern tube.

[0025] like Figure 4 As shown, when dismantling, use a wrench to relieve the force of the first bolt jackscrew 103 and the second bolt jackscrew 301, loosen the second bolt jackscrew 301 until the support body 3 contacts the regulating body 2, keep the support body 3 at a safe distance from the axial surface, use the external force of the crane to move the support body 3 along the axis and separate it from the trolley, and move the support body 3 out; then, use the same method to move the regulating body 2 out; finally, with the cooperation of manpower, use the crane to move the vehicle body 1 out from the side of the stern shaft 6.

[0026] By continuously dragging and adjusting the position of the trolley in time, the trolleys in place are removed in turn, and the stern shaft 6 is installed to the final position.

[0027] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
