Description

Technical Field

[0001] This invention relates to the technical field of diesel engine manufacturing industry, specifically to a lifting tool for marine diesel engine bracket modules. Background Technology

[0002] Lifting equipment is a device used to lift heavy objects; it is also known as lifting slings. It plays an important role in lifting and hoisting operations.

[0003] Currently, the commonly used large-scale main unit bracket grids have not yet fully formed a modular assembly, requiring frequent use of cranes, which increases energy consumption and personnel input. At the same time, the installation of bracket grids requires individual installation, which significantly increases the installation cycle of bracket grids.

[0004] Therefore, a new lifting tool for the bracket module needs to be designed, which is mainly suitable for the overall transportation and installation of the bracket module. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a lifting tool for marine diesel engine bracket modules. This addresses the issues raised in the background section, such as the fact that the main engine bracket grating has not yet been fully modularized, requiring frequent use of cranes, increasing energy consumption and manpower, and the need for individual installation of the bracket grating, which significantly extends the installation cycle.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a lifting tool for a marine diesel engine bracket module, comprising:

[0009] The first lifting tool body has a second lifting tool body on its back;

[0010] Support beams are provided on both sides between the first lifting tool body and the second lifting tool body. Lifting beams are provided on the front and rear parts of the upper surface of the support beams. Lifting lugs are installed on the upper surface of the lifting beams. First connecting plates are installed on the front and back of the support beams. First connecting plates are also installed at corresponding positions of the first lifting tool body, the second lifting tool body and the first connecting plate of the support beam. First bolts are screwed between the first connecting plates.

The second connecting plate and the module bracket assembly are screwed together with a second bolt. Nuts are screwed onto the surfaces of the first bolt and the second bolt.

[0012] Preferably, the inner cavity of the first lifting tool body is uniformly provided with support columns, and mounting plates are installed on the upper and lower surfaces of the support columns. A mounting rod is screwed between the mounting plate and the first lifting tool body. The support columns can reinforce the first lifting tool body, and the support columns can be fixed to the surface of the first lifting tool body by the mounting rod and the mounting plate.

[0013] Preferably, fixing rods are evenly screwed onto the right side of the lower surface of the module bracket assembly, and the lower part of each fixing rod is screwed onto the upper surface of the first lifting tool body. The fixing rods can connect the module bracket assembly to the first lifting tool body, thereby improving the stability of the module bracket assembly.

[0014] Preferably, the left side of the module bracket assembly is a fixing plate, and a first threaded rod is screwed between the fixing plate and the upper part of the module bracket assembly. Rotating the first threaded rod can connect the fixing plate to the surface of the module bracket assembly.

[0015] Preferably, the lower part of the module bracket assembly is a reinforcing beam, and a second threaded rod is screwed between the reinforcing beam and the fixing plate.

Figure 3 A second bolt 6 is screwed between the second connecting plate 61 and the module bracket assembly 11, and nuts 7 are screwed onto the surfaces of both the first bolt 5 and the second bolt 6.

[0031] The second lifting tool body 2 is welded with a second connecting plate 61 that matches the modular bracket assembly 11. The second lifting tool body 2 and the modular bracket assembly 11 are fastened together by the second bolts 6 and nuts 7. The two support beams 3 are connected to the first lifting tool body 1 and the second lifting tool body 2 by the first bolts 5 and nuts 7 to ensure the stability of the entire lifting tool. The position of the two support beams 3 takes into account the center of gravity balance of the modular bracket assembly 11 and the lifting angle range to ensure the safety of the lifting process. The four lifting beams 4 are connected to the second lifting tool body 2 and the two support beams 3 by the second bolts 6 and nuts 7 respectively. The lifting of the entire modular bracket assembly 11 is completed by the four lifting lugs 41. The modular bracket assembly 11 can be installed as a whole on the surface of the first lifting tool body 1 and the second lifting tool body 2, avoiding the installation of individual parts, greatly reducing the installation cycle of the modular bracket assembly 11, and also forming a modular assembly of the bracket grid, reducing the number of times the crane is used, reducing energy consumption, and also reducing personnel input.

[0032] Please see Figure 2 The inner cavity of the main body 1 of the first lifting tool is evenly provided with support columns 8. Please refer to [link / reference].

[0037] The device firstly consists of a modular bracket assembly 11, which is composed of a fixing plate 13 and a reinforcing beam 15. A second threaded rod 16 connects the reinforcing beam 15 to the surface of the fixing plate 13, and a third threaded rod 17 mounts the reinforcing beam 15 onto the surface of the modular bracket assembly 11. A fixing rod 12 connects the modular bracket assembly 11 to the first lifting tool body 1, improving the stability of the modular bracket assembly 11. Then, a second connecting plate 61, matching the modular bracket assembly 11, is welded onto the second lifting tool body 2. The second lifting tool body 2 is then securely connected to the modular bracket assembly 11 using second bolts 6 and nuts 7. Two support beams 3 are connected to the first lifting tool body 1 and the second lifting tool body 2 via first bolts 5 and nuts 7. The connection ensures the stability of the entire lifting tool. The selection of the positions of the two support beams 3 takes into account the center of gravity balance of the modular bracket assembly 11 and the lifting angle range to ensure the safety of the lifting process. The four lifting beams 4 are connected to the second lifting tool body 2 and the two support beams 3 respectively through the second bolts 6 and nuts 7. Finally, the four lifting lugs 41 are used to complete the lifting of the entire modular bracket assembly 11. The modular bracket assembly 11 can be installed as a whole on the surface of the first lifting tool body 1 and the second lifting tool body 2, avoiding the installation of individual parts, greatly reducing the installation cycle of the modular bracket assembly 11, and also forming a modular assembly of the bracket grid, reducing the number of times the crane is used, reducing energy consumption, and also reducing personnel input.
