Technical Field

[0001] This utility model relates to the field of gantry crane ship transport tower technology, specifically a gantry crane ship transport tower structure that is easy to hoist and manufacture. Background Technology

[0002] According to the needs of shipping complete gantry cranes, especially large gantry cranes, due to their large weight, high center of gravity, and complex and special structure, the long distances and unpredictable weather during cross-sea transportation by ships, as well as strong winds and waves, place extremely high demands on the lashing of cargo on ships. The cargo needs to be secured with strong and reliable sea lashing equipment, which requires the equipment to be highly safe, efficient, simple and convenient.

[0003] However, existing tower equipment has a fixed lifting unit position during use, which may limit the applicable scope of tower gantry structure lifting work and thus affect the work efficiency of tower gantry structure lifting work.

[0004] To address the aforementioned deficiencies, Chinese Patent No. CN220886733U discloses a tower gantry structure, including supports and an adjustment mechanism. Each support has a mounting groove at its lower end, and a mounting plate is fixedly connected to the lower end of each mounting groove. A crossbeam is fixedly connected to the upper end of each adjacent support, and sliding grooves are provided on the opposing inner surfaces of the left and right crossbeams. The adjustment mechanism includes a sliding plate, a screw, and a guide post. The screw is rotatably connected to the sliding groove on the left end, and the left end of the sliding plate is threaded to the middle of the screw. The guide post... The sliding plates are fixedly connected to the inside of the sliding groove on the right end. The right end of each sliding plate is slidably connected to the middle of the guide column to realize the longitudinal movement of the sliding plates. The sliding plates are slidably connected between the sliding grooves. Symmetrically distributed connecting plates are fixedly connected between the sliding plates. The end of each connecting plate near the center of the sliding plate is fixedly connected to a mounting base. A winch is rotatably connected between the mounting bases.

This effectively expands the applicable scope of tower gantry structure hoisting work and thus effectively improves the work efficiency of tower gantry structure hoisting work.

[0005] The aforementioned device utilizes an adjustment mechanism to achieve longitudinal displacement of the hoisting unit during use, which can meet different hoisting requirements. However, the tower assembly of the aforementioned device is relatively complicated during use, and it is easily affected by external factors, which can impact the applicable scope of hoisting operations.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figure 1 - Figure 2 The present invention provides the following technical solution: a gantry crane ship transport tower structure that is easy to hoist and manufacture, including a lower support 1, an upper support 2 at the top of the lower support 1, mounting blocks 7 at the four corners of the top of the upper support 2, a fixing seat 8 at the top of the mounting blocks 7, and a hoist fixing mechanism for easy installation at the top of the fixing seat 8.

[0019] The designed gantry fixing mechanism allows for quick and stable connection of lifting equipment to the tower structure, effectively improving lifting efficiency. This mechanism is rationally designed, easy to operate, and significantly shortens preparation time, saving valuable time throughout the transportation process. The stabilizing rods 4 at the four corners of the lower support 1, along with the support hinges 5 and support rods 3, form a robust support system. During ship transport, this system effectively resists external impacts from strong winds and waves, ensuring the stability of the tower structure and preventing swaying or tilting, thus ensuring cargo safety during transport. The limiting rod 6 further enhances the stability of the tower structure by restricting the movement range of related components on the inner side of the lower support 1, preventing structural imbalance due to excessive component displacement and providing additional safety for the entire tower structure. The lifting lugs 13 and mounting components 14 in the gantry fixing mechanism not only facilitate the installation of lifting equipment but also utilize high-quality materials. The material and structural design have been carefully considered, possessing high strength and durability, capable of withstanding significant lifting forces, ensuring no breakage or damage occurs during lifting. The mounting platform 10 and support plate 11 at the top of the fixed base 8 provide a solid support foundation for the entire tower structure. The design of the mounting platform 10 allows the support plate 11 to be securely installed on it, and the support plate 11 is connected to the ladder 9 through the fixed base 8, facilitating climbing and operation for workers, improving work convenience and safety. The ladder 9 is designed with the actual needs of workers in mind, and its material and structure conform to ergonomic principles, ensuring comfort and safety during climbing. The connection between the ladder 9 and the fixed base 8 is firm and reliable, preventing loosening or detachment. The clamping block 12 at the top of the support plate 11, through welding, effectively fixes relevant components during the lifting process, preventing slippage or displacement during transportation, thereby ensuring the accuracy and stability of the lifting work.

[0020] Example 2: Based on Example 1, this example solves the problem of low efficiency caused by the structural fixation and cumbersome assembly of traditional tower cranes during hoisting. Please refer to [link / reference]. Figure 2 - Figure 5 The stabilizer bar 4 was also disclosed, and its specific structure is as follows: the stabilizer bar 4 is welded to the top four corners of the lower bracket 1, the outer surface of the stabilizer bar 4 is provided with a support hinge 5, the outer surface of the support hinge 5 is welded with a support rod 3, the inner side of the lower bracket 1 is provided with a limit rod 6, the hanger fixing mechanism includes a lifting lug 13, the lifting lug 13 is welded to the top of the fixing seat 8, and the top of the fixing seat 8 is fixedly installed with an installation part 14.

[0021] Before assembly, the lower support 1 of the tower is made into sections, transported to the assembly site, and assembled. The joints between the two sections are not welded at the moment, and the diagonal bracing at the bottom that connects to the ship's deck is not welded at the moment. The upper support 2 of the tower is made as a whole, and the diagonal bracing on one side of the column is not welded at the moment (it will be welded after it is loaded onto the ship) to facilitate tower repositioning. After the above assembly is completed, the gantry crane is used to lift and turn each section into an upright position. The upper support 2 of the tower and the lower support 1 of the tower are first joined together to form a component, and then the whole assembly is lifted and then joined together to complete the overall assembly and joining of the tower. The joints are welded, and all welds are subject to ultrasonic UT100% inspection.

[0022] Example 3: Based on Example 1, this example addresses the shortcomings of traditional tower structures in terms of ease of operation and safety. Please refer to [link / reference]. Figure 3 - Figure 6 The installation platform 10 was also disclosed, and its specific structure is as follows: the top of the fixed base 8 is fixedly installed with the installation platform 10, the outer surface of the installation platform 10 is provided with a support plate 11, the bottom surface of the support plate 11 is fixedly installed with the fixed base 8, the outer surface of the fixed base 8 is provided with a ladder 9, and the top of the support plate 11 is welded with a clamping block 12.

[0023] Through the rational layout and design of the mounting platform 10, support plate 11, fixing seat 8, ladder 9, and clamping block 12, the entire tower structure not only possesses high strength and stability but also greatly facilitates the operation and maintenance of workers. The dimensions and shape of the mounting platform 10 are precisely calculated to perfectly fit the support plate 11, providing stable support for the support plate 11. The support plate 11 is made of high-strength material, capable of withstanding significant pressure and tension, ensuring that it will not deform or be damaged during hoisting. The fixing seat 8 not only tightly connects to the support plate 11 but also provides a stable installation foundation for the ladder 9. The step height and width of the ladder 9 are designed according to ergonomic principles, allowing workers to maintain a comfortable posture and reduce fatigue during climbing. The clamping block 12 is fixed to the top of the support plate 11 through precise processing and welding, enabling precise fixation of relevant components during hoisting and ensuring the smooth progress of the hoisting work. This overall design not only improves the performance of the tower structure but also reduces the operational difficulty and safety risks for workers, providing a more reliable and efficient solution for gantry crane shipping.
