The turning-over tool has the advantages of simple structure, low cost, safety, high efficiency and strong universality, and can be suitable for turning-over operation of the cylinder covers with various sizes.
Description
Technical Field
The utility model relates to manufacturing equipment of a marine diesel engine, in particular to a turning-over auxiliary tool for a large-scale low-speed marine diesel engine cylinder cover, and belongs to the technical field of mechanical manufacturing.
Background
The cylinder cover of the large marine low-speed diesel engine is of a revolving body structure and generally has the characteristics of large size (the maximum excircle diameter is 1800mm) and heavy weight (the finished product is 3-8 tons). In the processing process, the cylinder cover is often required to be lifted and turned over, the lifting and turning process of the cylinder cover is time-consuming and labor-consuming, and a large safety risk exists.
The existing cylinder cover turning-over operation is to directly pass a steel wire rope through a through hole on a cylinder cover body for carrying out pocket hanging, then to continuously adjust the position of the steel wire rope to find a proper hanging point, so that the cylinder cover reaches an ideal inclination angle, then to place the best stress point of the cylinder cover on the steel wire rope by taking one or more independent sleepers capable of freely moving as fulcrums, and then to slowly put down the steel wire rope to complete the turning-over. The turning-over mode needs to repeatedly adjust the stress position of the steel wire rope, and meanwhile, the movable sleepers are easy to displace when being in contact with the cylinder cover, and are easy to slip when a plurality of sleepers are superposed and stressed, so that the cylinder cover is in an unbalanced and unstable state in the turning-over process, and easily sideslips, and safety accidents of turning-over operation are caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defect of the existing cylinder cover turning mode, provides a simple, efficient and safe turning auxiliary tool for a large-scale low-speed marine diesel engine cylinder cover, solves the problem of gravity center balance in the cylinder cover hoisting process, ensures that the cylinder cover turning operation is safer, avoids safety accidents caused by no effective support, and reduces the safety risk of the operation.
The technical scheme adopted for solving the technical problems is as follows:
the utility model provides a stand up auxiliary fixtures that is used for large-scale low-speed marine diesel cylinder head which characterized in that: the lifting device comprises a step type frame, an upper sleeper and a lower sleeper; the step type frame is formed by welding steel plates and is fixed on the ground, the step type frame is provided with a lower groove and an upper groove which are arranged in a step type mode, the lower sleepers are installed in the lower groove, and the upper sleepers are installed in the upper groove.
Furthermore, the lower part of the step type frame is provided with a plurality of mounting feet, and the mounting feet are provided with fixing holes for being connected with the ground.
Further, the step frame is fixed on the ground through expansion screws.
Compared with the traditional turning-over method, the utility model has the following advantages:
1. the utility model takes the sleepers in the step type frame fixed on the ground as stressed fulcrums, thereby avoiding the sideslip or overturn of the cylinder cover caused by the unfixed sleepers in the turnover process, ensuring that the turnover process is more stable and reliable, and eliminating potential safety hazards.
2. The turnover tool is simple in structure and low in cost, and the turnover operation is completed by utilizing the height difference between the tool and the ground, so that the requirement of the turnover operation of the cylinder cover is met.
3. The turnover device has strong universality, safety and high efficiency, and can be suitable for turnover operation of cylinder covers with various sizes.

Detailed Description
The utility model and its method of use are described in further detail in connection with the accompanying drawings and the following examples, which should not be construed as limiting the scope of the utility model as claimed.
The utility model is used for turning over the cylinder cover of the low-speed marine diesel engine.
Referring to fig. 1 and 2 in combination, a turning-over assisting tool is shown to be placed in a suitable place and fixed on the ground, and comprises a step-type frame 1, an upper sleeper 3 and a lower sleeper 2.
Referring to fig. 3 and 4, the step frame 1 is formed by welding steel plates of different shapes, and includes a plurality of mounting legs 11, a lower groove 12 and an upper groove 13; the lower groove 12 and the upper groove 13 form a step-type arrangement, the mounting leg 11 is arranged at the lower part of the step-type frame 1, and the mounting leg 11 is provided with a fixing hole 14 for fixedly connecting with the ground through an expansion screw.
Referring to fig. 1, the lower sleeper 2 is installed in the lower groove 12, and the upper sleeper 3 is installed in the upper groove 13.
The following are two ways of turning over the cylinder cover by using the utility model.
Referring to the case that the cylinder cover is turned over from the small end in fig. 5, firstly, a steel wire rope WR penetrates through the cylinder cover CC to be hung, a proper hanging point is found by adjusting the position of a shackle SK, the cylinder cover CC is lifted and then moved to the position above the turning-over auxiliary tool, and after the outer circle of the large end of the cylinder cover CC is contacted with an upper sleeper 3, a main hook and the steel wire rope WR are slowly lowered until the cylinder cover CC is turned over to the horizontal position.
Referring to fig. 6, in the case that the cylinder head is turned over from the large end, similarly, a steel wire rope WR penetrates through the cylinder head CC to be hung, a proper hanging point is found by adjusting the position of the shackle SK, the cylinder head CC is lifted and then moved to the position above the turning-over auxiliary tool, and after the outer circle of the small end of the cylinder head CC is in contact with the upper sleeper 3, the main hook and the steel wire rope WR are slowly lowered, so that the large end of the cylinder head CC falls to the lower sleeper 2 until the cylinder head CC is in the horizontal position to realize turning over.
The above-described embodiments are not intended to limit the scope of the present invention, and the scope of the present invention is not limited to the above-described embodiments, but also includes other modifications and alternatives obvious to the present invention. All equivalent changes and modifications made according to the content of the present application should be within the technical scope of the present invention.
