Description

Technical Field

[0001] The present application relates to the field of ship deck manufacturing equipment, and in particular to a special combined support tooling for PCTC movable decks. Background Art

[0002] As specialized vehicle carriers, PCTC vessels typically feature multi-layered, retractable decks in their cargo holds to accommodate the loading height requirements of various vehicle types. During construction, these decks must be installed layer by layer using large lifting equipment onto support blocks atop the interior columns. Because the accuracy of the deck's installation directly impacts the safety and efficiency of roll-on / roll-off vehicle operations, the flatness of the support system is extremely stringent.

[0003] If a local gap or excessive pressure develops between the movable deck and the support base after it is in place, the thickness of the adjustment pads on the support base must be repeatedly reground to achieve millimeter-level precision. Traditionally, the deck is continuously suspended by a crane for leveling. Operators measure the gap in real time while the deck is suspended, then remove the pads for machining and trimming before reinstalling the crane for verification.

[0004] With regard to the above-mentioned related technologies, the inventors believe that the leveling of a single deck requires the crane to maintain precise hovering for several hours or even longer, which seriously restricts the efficiency of the crane's use in other key processes in the assembly site, will occupy a large amount of crane resources, and result in a long installation period for the movable deck.

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0027] As specialized vehicle carriers, PCTC vessels typically feature multi-layered, retractable decks in their cargo holds to accommodate the loading height requirements of various vehicle types. During construction, these decks must be installed layer by layer using large lifting equipment onto support blocks atop the interior columns. Because the accuracy of the deck's installation directly impacts the safety and efficiency of roll-on / roll-off vehicle operations, the flatness of the support system is extremely stringent.

[0028] If a local gap or excessive pressure develops between the movable deck and the support base after it is in place, the thickness of the adjustment pads on the support base must be repeatedly reground to achieve millimeter-level precision. Traditionally, the deck is continuously suspended by a crane for leveling. Operators measure the gap in real time while the deck is suspended, then remove the pads for machining and trimming before reinstalling the crane for verification.

[0029] With regard to the above-mentioned related technologies, the inventors believe that the leveling of a single deck requires the crane to maintain precise hovering for several hours or even longer, which seriously restricts the efficiency of the crane's use in other key processes in the assembly site, will occupy a large amount of crane resources, and result in a long installation period for the movable deck.

[0030] In order to effectively improve the installation efficiency of the movable deck, increase the utilization rate of the crane, and avoid occupying crane resources for a long time, the present application provides a special combined support tooling for the PCTC movable deck.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses a PCTC movable deck dedicated combined support tooling. Figure 1 、 Figure 2 A dedicated combined support tooling for a PCTC movable deck includes a tubular base 1 with a fine-tuning assembly at its bottom for adjusting its height. A heightening assembly 2 is also located at the top of the base 1 to adjust the overall height of the equipment so that the base 1 fits better with the movable deck.

[0033] An upper support plate 11 is horizontally provided at the top end of the base 1 , and the upper support plate 11 is fixedly connected to the base 1 . A lower support plate 12 is horizontally provided at the bottom end of the base 1 , and the lower support plate 12 is fixedly connected to the base 1 .

[0034] In some embodiments, the fine-tuning assembly includes an oil pump located below the base 1, the top of the oil pump is connected to the lower support plate 12, and the oil pump includes a cylinder end, the interior of the cylinder end is slidably connected to a piston end, the piston end slides relatively inside the cylinder end under the push of the pressurized oil, and the piston end is fixedly connected to the lower support plate 12, thereby driving the entire base 1 to move in the height direction through the oil pump.

[0035] Reference Figure 1 、 Figure 4 A reinforcement member 3 is also provided at the top of the lower support plate 12. The reinforcement member 3 is located inside the base 1, and the reinforcement member 3 is fixedly connected to the inner side wall of the base 1, and the bottom end of the reinforcement member 3 is fixedly connected to the lower support plate 12. The reinforcement member 3 is used to strengthen the lower support plate 12 to reduce the damage to the lower support plate 12 caused by the oil pump during driving.

[0036] The reinforcement member 3 includes a first reinforcement rod 31 and a second reinforcement rod 32 arranged opposite to each other. The first reinforcement rod 31 and the second reinforcement rod 32 are rod-shaped structures.
