[0003] When a large diesel engine is assembled and installed, in-machine operations are inevitable. To avoid interference with moving parts, the space available for operations inside the machine is limited. Therefore, it is difficult to control the standing positions and force application points of the operators. Moreover, the oil stains and the like inside the machine have a greater impact on in-machine operations, increasing the danger of operations and leaving the personal safety of the personnel unguaranteed.

[0004] In the prior art, Chinese Utility Model Patent CN205078341 U discloses a pedal and handrail inside the frame of a marine low-speed diesel engine, which uses an oval hole opened on the crosswise plate inside the frame as a climbing pedal and also enables it to have the function of a handle to achieve operations such as assembly and maintenance inside the frame. However, this structure has the following problems: 1. The space inside the main engine is large, and there is no designed suitable standing area during the overhaul, disassembly, and assembly operations of moving parts, making the operations difficult; 2. The contact area of the in-machine step is small, and the operators cannot stand steadily; standing for a long time easily causes fatigue; 3. When the space inside the main engine is small, the operator's body cannot be fully stretched when standing on the step; there are safety hazards. Therefore, the above structure has many inconveniences when performing operations inside the main engine. Summary of the Utility Model

The support structure and the step structure are vertically arranged, where the support structure is vertically arranged and the pedal structure is horizontally arranged. The support structure forms a clamping groove and is clamped in the waist-shaped hole on the diesel engine frame. The support structure provides support for the step structure. The step structure is welded to the lower part of the support structure. The step structure and the support structure are integrally in an L shape, and a standing platform is provided for the operator through the pedal structure.

[0031] In this embodiment, the support structure includes a first baffle 3, a second baffle 4 and a support block 2. The first baffle 3 and the second baffle 4 are arranged in parallel. The support block 2 is located between the first baffle 3 and the second baffle 4. The first baffle 3, the second baffle 4 and the support block 2 form a clamping groove for being clamped in the waist-shaped hole on the frame or at the position that needs to be clamped on the frame.

[0032] In this embodiment, the support block 2 is of a U-shaped structure. The two sides of the support block 2 are respectively welded to the first baffle 3 and the second baffle 4. The two ends of the support block 2 are higher than the upper surfaces of the first baffle 3 and the second baffle 4. Threaded holes are respectively arranged on the two end parts of the support block 2, and jacking bolts 1 are installed in the threaded holes. The jacking bolts 1 press against the end face of the waist-shaped hole to realize the locking of the support block.

[0033] Furthermore, semi-circular grooves are arranged at the upper ends of the first baffle 3 and the second baffle 4. The semi-circular grooves correspond to the bottom of the U-shaped structure of the support block. The installation of the jacking bolts is facilitated by the arranged semi-circular grooves. The clamping stability of the support structure is improved by the arranged two baffles. The support structure is further closely attached to the waist-shaped hole on the frame by the arranged jacking bolts, and the installation stability of the whole tooling is further improved.

[0034] In this embodiment, the support block 2 and the waist-shaped hole on the diesel engine structure adopt a small clearance fit in the circumferential direction. The thickness of the support block is greater than the thickness of the waist-shaped hole. Specifically, the thickness of the support block is 1-2 mm greater than the thickness of the diesel engine structure steel plate. Stable support is provided for the whole tooling through the waist-shaped hole.

[0035] In this embodiment, the step structure includes a first support plate 6, a second support plate 7 and a pedal 5. The first support plate 6 is vertically welded at the middle position of the second support plate 7. The pedal 5 is welded on the first support plate 6 and the second support plate 7.

[0036] Furthermore, the end part of the first support plate 6 is welded to the step structure to realize the installation of the support structure and the step structure.

[0037] In this embodiment, the pedal is made of an anti-slip patterned plate, which provides a standing platform for the operator and can play an anti-slip role to ensure the safety of the operator.

[0038] The installation process of the internal step tooling of the diesel engine provided in this embodiment is as follows:

[0039] First, weld the first baffle 3 and the second baffle 4 to the support block 2, then connect the first support plate 6, the second support plate 7, the second baffle 4 and the pedal 5 by welding, and finally screw the jacking bolt 1 into the threaded hole on the support block 2.

[0040] During use, only need to engage the card slot formed by the first baffle 3, the second baffle 4 and the support block 2 to the corresponding position, and then tighten the jacking bolt so that the end of the jacking bolt presses against the end face of the installation position, then the step tooling 9 can be installed on the frame 8 of the diesel engine. As Figure 3 and 4 shown. After the assembly is completed, only need to disassemble the step tooling, which will not occupy the internal space of the diesel engine and has the advantages of convenient disassembly and assembly.
