Description

Technical Field

[0001] This utility model relates to the technical field of ship hull translation and assembly devices, specifically a translational giant ship hull section assembly device. Background Technology

[0002] Hull assembly is a core technology in shipbuilding, referring to the process of assembling prefabricated giant hull modules into a complete hull in a slipway or dry dock according to design precision. When assembling hull sections, auxiliary assembly devices are needed to position the assembly position.

[0003] For example, publication number CN105667710A (titled "A Transposition and Positioning Device and Method for a Ship's Annular Section") includes a power module vehicle, a positioning device, and a control device. The power module vehicle is used to translate the annular section. The positioning device is a tracking total station used to acquire the position information of the annular section transported by the power module vehicle in real time. The control device is electrically connected to both the power module vehicle and the tracking total station, and is used to receive the position information of the annular section and control the power module vehicle to transport the annular section to a set target position. The power module vehicle includes a module vehicle and a power head located at one end of the module vehicle. Multiple module vehicles can be driven side-by-side laterally and / or longitudinally. The control device is electrically connected to the power head. The translation and positioning device and method use a module vehicle as the translation equipment, and multiple module vehicles can be combined according to the tonnage of the annular section. It has a wide range of applications, and the positioning device and control device achieve precise positioning while the module vehicle is being translated, which is safe and efficient.

[0004] The aforementioned hull translation positioning device assists in the positioning of hull modules by setting up a translation carrier structure. However, after the hull is joined, there is a lack of effective fixing mechanism between the two modules, which makes it easy for the hull to loosen after joining. To address this, we provide a translational giant hull section joining device. Utility Model Content

[0005] The purpose of this utility model is to provide a translational giant hull section assembly device to solve the problem mentioned in the background art that the existing hull translational positioning device uses a set translational carrier structure to assist in the assembly and positioning of hull modules, but the lack of an effective fixing mechanism between the two modules after the hull is assembled makes it easy for the hull to loosen after assembly.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a translational giant hull section assembly device, including translational guide seats, two translational guide seats are provided, two translational carriers are provided above the two translational guide seats, and four movable joint seats are welded to the bottom of each of the two translational carriers, with two adjacent movable joint seats being movably connected to one translational guide seat.

[0007] Also includes:

[0008] The central support is welded and set at the middle section of the two translation guide seats, and the upper end of the central support is fixed with a second hydraulic cylinder by screws. Two crossbeam plates are symmetrically welded at one end of the piston rod of the second hydraulic cylinder, and crossbeam plates are welded at the lower end of the two crossbeam plates.

[0009] A threaded push rod is movably disposed inside the crossbeam clamping plate, and a handle and a clamping head are welded to both ends of the threaded push rod, respectively.

[0010] Vertical columns are welded to the upper end of the translation vehicle. There are four vertical columns, and three rope loops are welded to the inner wall of each of the four vertical columns. A first hydraulic cylinder is installed on the inner side of each of the four vertical columns. The four first hydraulic cylinders are fixedly connected to the translation vehicle by screws. A support top is welded to the top of the piston rod of each first hydraulic cylinder.

[0011] Preferably, both translation guide seats have guide inner rods welded inside, and guide holes are provided at the connection positions of the movable seat and the guide inner rods. The movable seat is guided and movably connected to the translation guide seat through the guide holes.

[0012] Preferably, an inner roller is movably disposed in the bottom groove of the movable connector via a bearing and a connecting shaft, and the movable connector is rolledly connected to the translation guide via the inner roller.

[0013] Preferably, a transmission screw hole is provided at the movable position where the threaded top rod and the crossbeam clamping plate pass through, and the transmission screw hole and the crossbeam clamping plate are an integral structure.

[0014] Preferably, one end of each of the translation vehicles is welded with an end seat, and a traction ring is welded to the lower inner wall of the end seat.

[0015] Preferably, both ends of the crossbeam plate are provided with ship receiving seats, and both ship receiving seats are welded to the crossbeam plate.

[0016] Preferably, each end of the translation guide is provided with two mounting end blocks, and the four mounting end blocks are integrated with the translation guide as a single structure.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention uses a second hydraulic cylinder to lower two crossbeam clamping plates. Bolts are installed in the receiving seat to fix the crossbeam clamping plates to the two giant hull modules. Finally, rotating the handle drives the threaded push rod to move along the crossbeam clamping plates, so that the clamping head abuts against the edge of the hull module's closing end, thereby clamping and fixing the two giant hull modules at the closing position. This overcomes the problem that existing hull translation and positioning devices use a translation vehicle structure to assist in the hull module's closing and positioning, but lack an effective fixing mechanism between the two modules after the hull is closed, which makes it easy for the hull to loosen after closing.
