Description

Technical Field

[0001] This utility model relates to the field of marine motor maintenance technology, and in particular to an auxiliary track for marine motor maintenance. Background Technology

[0002] Marine generator sets are power generation devices specifically designed for ships and similar environments, providing a stable and reliable power supply to vessels at sea. They are a crucial piece of equipment on board, responsible for providing a stable and reliable power source to ensure the ship's normal operation and the proper functioning of its various equipment.

[0003] Marine generator sets are located in the ship's engine room below deck and consist of a diesel engine and a generator mounted on a common base and connected by a coupling. Due to the generator's complex structure and prolonged use, its failure rate is relatively high. Common faults include difficulty starting the generator, excessive noise, and constant vibration. Therefore, generators require maintenance after prolonged operation. During generator maintenance, it is usually necessary to disconnect the entire generator from the diesel engine before proceeding. However, due to space limitations and the crane capacity of the ship's engine room, it is impossible to easily lift the entire generator. The only option is to use a crane on the dock to lift the entire generator ashore for maintenance after the ship is moored. However, this method of lifting the entire generator ashore requires time to coordinate lifting equipment, select suitable times, and consider weather conditions. These factors all extend maintenance time, affecting the ship's normal operation, and incurring additional lifting costs, leading to an increase in overall maintenance costs. Furthermore, lifting the entire generator ashore involves complex operating procedures and strict safety requirements, requiring specialized technicians and equipment, increasing the operational difficulty and risk. Summary of the Invention

[0004] To address the shortcomings of the existing technology, a marine motor maintenance auxiliary track is provided, which facilitates on-site maintenance of the generator without the need to hoist the entire generator ashore, reducing the impact of generator maintenance on the normal operation of the ship, eliminating the need for additional hoisting costs, and lowering maintenance costs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is a marine motor maintenance auxiliary track, which includes multiple spaced bases, support columns at both ends of the upper surface of each base, a support guide mechanism for connecting the support columns at the same end, a positioning frame that docks with the support guide mechanism at one end of each of the two support guide mechanisms, a lifting device on each positioning frame, and a carrying trolley that runs along the positioning frame and the support guide mechanism.

[0006] The aforementioned auxiliary track for ship motor maintenance includes a base comprising two parallel horizontal plates and a first vertical plate disposed between the two horizontal plates for connecting them. Multiple first reinforcing plates are provided on both sides of the first vertical plate to strengthen the connection between the two horizontal plates.

[0007] The aforementioned auxiliary track for ship motor maintenance includes a support and guide mechanism comprising a first support plate on a support column at the same end, a second support plate above the first support plate, a second longitudinal plate between the first and second support plates for connecting the two, and multiple second reinforcing plates on both sides of the second longitudinal plate for strengthening the connection between the first and second support plates.

[0008] The aforementioned auxiliary track for ship motor maintenance has first limiting plates on both sides of the second support plate.

[0009] The aforementioned auxiliary track for ship motor maintenance includes a positioning frame comprising a base plate, an upright plate disposed on the base plate, and a third support plate disposed on the upright plate with its surface flush with the surface of the second support plate, wherein a through cavity is provided on the third support plate.

[0010] The aforementioned auxiliary track for marine motor maintenance includes a lifting device comprising a hydraulic cylinder and a plate mounted on the output shaft of the hydraulic cylinder.

[0011] The aforementioned auxiliary track for ship motor maintenance includes a carrier trolley comprising a carrier plate, second limiting plates on both sides of the upper surface of the carrier plate, and rollers at the bottom of the carrier plate.

[0012] The aforementioned auxiliary track for marine motor maintenance has a fixed cylinder on the second support plate for insertion into the support column.

[0013] The beneficial effects of this utility model's auxiliary track for ship motor maintenance are as follows: Multiple bases are spaced apart, with support columns at both ends of the upper surface of each base, and a support guide mechanism connecting the support columns at the same end. A positioning frame is installed at one end of each support guide mechanism, and a lifting device is installed on each positioning frame. A carrying trolley runs along the positioning frame and support guide mechanism. This facilitates on-site maintenance of the generator, eliminating the need to hoist the entire generator ashore, reducing the impact of generator maintenance on normal ship operations, eliminating additional hoisting costs, and lowering maintenance costs.

[0014] By providing a fixing cylinder on the second support plate for insertion into the support column, the support column and base can be detached. When not in use, the detachable structure makes it easier to move to less frequently used areas compared to the whole unit. Furthermore, the support column and base can be separated, allowing the base to be placed on the second support plate for storage, thus reducing the lateral space occupied.

Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figure 1-2 As shown, a marine motor maintenance auxiliary track includes multiple spaced-apart bases. Support columns 1 are provided at both ends of the upper surface of each base. It also includes a support guide mechanism for connecting the support columns 1 at the same end. A positioning frame is provided at one end of each support guide mechanism to mate with it. A lifting device is provided on each positioning frame. The lifting device includes a hydraulic cylinder 13 and a plate 14 mounted on the output shaft of the hydraulic cylinder. It also includes a carrying trolley that runs along the positioning frames and support guide mechanisms. The carrying trolley includes a carrying plate 15, with second limiting plates 16 on both sides of the upper surface of the carrying plate 15, and rollers 17 at the bottom of the carrying plate 15.

[0022] The base includes two parallel horizontal plates 2 and a first vertical plate 3 located between the two horizontal plates 2 for connecting the two. Multiple first reinforcing plates 4 are provided on both sides of the first vertical plate 3 to strengthen the connection between the two horizontal plates 2.

[0023] The support and guiding mechanism includes a first support plate 5 mounted on a support column 1 at the same end, a second support plate 6 above the first support plate 5, a second longitudinal plate 7 connecting the first support plate 5 and the second support plate 6, and multiple second reinforcing plates 8 on both sides of the second longitudinal plate 7 to strengthen the connection between the first support plate 5 and the second support plate 6. First limiting plates 19 are provided on both sides of the second support plate 6.

[0024] The positioning frame includes a base plate 9, an upright plate 10 disposed on the base plate 9, and a third support plate 11 disposed on the upright plate 10 and whose surface is flush with the surface of the second support plate 6. A through cavity 12 is provided on the third support plate 11.

[0025] The method of using this utility model is as follows: First, remove the fasteners of the coupling connecting the diesel engine output shaft and the generator rotor shaft. Then, lift the generator stator housing base using the lifting device on the positioning frame. Next, place the carrying trolley below the generator stator housing base. Lower the lifting device to allow the generator stator housing base to fall onto the carrying trolley. Then, lower the lifting device below the cavity. Finally, connect the hand-operated hoist in the ship's engine room to the holes on the ear plate of the generator stator housing base, and then manually pull the generator stator housing base onto the second support plate for maintenance. With the above structure, the generator can be maintained on-site without lifting the entire generator ashore, reducing the impact of generator maintenance on the normal operation of the ship, eliminating additional hoisting costs, and lowering maintenance costs.

[0026] Example 2

[0027] The similarities between this embodiment and Embodiment 1 will not be repeated here. The differences are as follows: Figure 3 As shown, a fixing cylinder 18 for insertion into the support column 1 is provided on the second support plate 6. With the above structure, the support column 1 and the base are detachable. When not in use, the detachable structure is easier to move to areas with low usage compared to the whole structure. Moreover, the support column 1 and the base can be separated. When storing, the base can be placed on the second support plate 6, reducing the lateral space occupied.

[0028] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
