For example, the air release valve needs to be opened to blow the cylinder before starting the engine, the explosion pressure of the diesel engine needs to be detected, and the cylinder needs to be removed during maintenance. Operators climb up and down on the diesel engine, so it is necessary to design a maintenance platform to facilitate maintenance.
[0003] Currently, marine engine maintenance platforms are mainly fixed to the outside of the engine by bolts, and the entire inspection platform is assembled by bolts. However, the layouts of diesel engines on ships vary greatly, and the external layout environments of diesel engines also vary greatly. The maintenance part may interfere with the maintenance platform, and the assembly of some components is relatively troublesome. According to different layouts, the guardrails and handrails and the up-and-down ladders of the maintenance platform need to be interchanged positions, and the guardrails and handrails and the up-and-down ladders are connected by bolts, and disassembly requires tools. There is a risk of thread stripping over a long time, and the assembly efficiency is low, so it cannot be applied to most environments.
[0004] Therefore, it is necessary to provide a new marine diesel engine maintenance platform to solve the above technical problems. Content of the Utility Model

[0028] In the specific implementation process, as Figures 1 - 9 shown, a diesel engine maintenance platform for ships provided by the present invention includes a fixing device 2, a maintenance tabletop 3, a guardrail handrail 1, and an up-and-down ladder 6. The fixing device 2 is welded to the maintenance tabletop 3, and the guardrail handrail 1 and the up-and-down ladder 6 are respectively embedded in the fixing device 2;
[0029] The fixing device 2 includes a U-shaped bracket 21, a cabin body 22, a fixing bracket 25, a spring 221 and a connecting rod 222. The U-shaped bracket 21 is welded to the side of the maintenance tabletop 3. One end of the U-shaped bracket 21 away from the maintenance tabletop 3 is fixedly connected to the cabin body 22, and rectangular slots for the fixing bracket 25 to pass through are formed through the cabin body 22 and the U-shaped bracket 21. One end of the fixing bracket 25 is fixedly connected with a trapezoidal convex block, and the end of the fixing bracket 25 away from the trapezoidal convex block is fixedly connected to the connecting rod 222. The connecting rod 222 passes through a circular through-hole formed in the cabin body 22, and the radial dimension of the connecting rod 222 located in the cabin body 22 is larger than the radial dimension of the circular through-hole. A pull ring 24 is arranged at one end of the connecting rod 222 away from the fixing bracket 25. Both ends of the spring 221 are fixedly connected to the rectangular slot of the cabin body 22 and the side wall of the fixing bracket 25 respectively.
[0030] It should be noted that the radial dimension of the connecting rod 222 located in the cabin body 22 being larger than the radial dimension of the circular through-hole can prevent the fixing bracket 25 from being ejected out of the cabin body 22 by the spring 221, and a pull ring 24 arranged at one end of the connecting rod 222 away from the fixing bracket 25 can easily pull out the fixing bracket 25.
[0031] It should be noted that when there is interference between the guardrail handrail 1 and the maintenance position, the guardrail handrail 1 may not be installed.
[0032] Support devices are arranged at the bottom of the maintenance tabletop 3. The support devices include a plurality of support legs 5. The tops of the plurality of support legs 5 are fixedly connected to the bottom of the maintenance tabletop 3 through bolts, and fixing plates 4 are fixedly connected between adjacent support legs 5 through bolts.
[0033] When assembling the support legs 5 of the maintenance platform, use bolts to connect and fix the maintenance tabletop 3 and the support legs 5, and fixedly connect the fixing plates 4 between every two support legs 5 through bolts.
[0034] Positioning blocks 11 are respectively arranged on the guardrail handrail 1 and the up-and-down ladder 6. Rectangular grooves are formed in the positioning blocks 11, and the cross-sectional dimensions of the rectangular grooves match the cross-sectional dimensions of the trapezoidal convex blocks. Thus, the trapezoidal convex blocks can be completely embedded into the rectangular grooves to ensure the stability during connection.
[0035] It should be noted that the top of the up-and-down ladder 6 is provided with a positioning block 11 having the same structure as the guardrail handrail 1 and fixedly connected to the up-and-down ladder 6. The installation method and disassembly method are the same as those of the guardrail handrail 1. Thus, high-efficiency assembly and disassembly work can be achieved. The assembled entire maintenance platform can be placed at any maintenance position, which can be the ground or a pedestal. Combining the actual situation, the positions of the guardrail handrail 1 and the up-and-down ladder 6 can be converted.
[0036] Optionally, a reinforcing rod can also be fixedly connected in the middle of the guardrail handrail 1 to increase its stability.
[0037] The inner side wall of the U-shaped bracket 21 is fixedly connected with a U-shaped base 27, and the U-shaped base 27 can be fixedly connected with the side surface of the maintenance table 3.
[0038] The working principle provided by the present utility model is as follows: When installing the guardrail handrail 1 or the up and down ladder 6, the positioning block 11 fixedly connected to the bottom of the guardrail handrail 1 only needs to be inserted into the fixing device 2 on the side surface of the maintenance table 3. Through extrusion, the fixing bracket 25 is compressed inward. When the positioning block 11 at the bottom of the guardrail handrail 1 is compressed to the bottom of the fixing device 2, the spring 221 inside the fixing device 2 will eject the fixing bracket 25. The trapezoidal structure of the fixing bracket 25 is embedded in the rectangular groove of the positioning block 11, so that the guardrail handrail 1 is subjected to the limiting force in the horizontal and vertical directions, thereby achieving the purpose of fixing the guardrail handrail 1. The bottom of the fixing device 2 is fixedly connected with a U-shaped base 27, which can support the guardrail handrail 1 to ensure that it will not slide down. The guardrail handrail 1 and the up and down ladder 6 can be interchanged in position and can also be quickly disassembled;
[0039] When disassembling the guardrail handrail 1 or the up and down ladder 6, it is necessary to pull the pull ring 24. The pull ring 24 is connected to the fixed connecting rod 222, and the connecting rod 222 is connected to the fixed fixing bracket 25. When the pull ring 24 is pulled, the spring 221 is compressed, and the trapezoidal structure fixedly connected to the fixing bracket 25 is pulled out from the rectangular groove of the positioning block 11, and the spring 221 is compressed. At this time, the guardrail handrail 1 or the up and down ladder 6 can be easily pulled out, so as to realize the quick disassembly and assembly of the guardrail handrail 1.
[0040] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, are similarly included in the patent protection scope of the present utility model.
