Description

Technical Field

[0001] The utility model relates to the field of marine diesel engines, in particular to a marine diesel engine base single-piece wing plate assembly and flipping safety auxiliary device. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] The engine base section of a marine diesel engine is an important component of the main body of the engine base and the main structural component that supports the movement of the crankshaft. There is a risk of positioning weld fracture during the assembly of the wing plate and the intermediate bearing seat and the first welding flipping process. Since the assembly and welding of the engine base section are high-frequency operations, the safety of the construction work is further reduced.

[0004] When assembling the segmented wing plate of the machine base and the intermediate bearing seat, since the height exceeds 2 meters, the relative position relationship between the top wing plate and the intermediate bearing seat is difficult to flexibly adjust. The existing conventional operation method uses the method of spot welding positioning blocks and wedge irons to adjust the position of the wing plate. The inventor found that the method of spot welding positioning blocks and wedge irons requires spot welding of multiple positioning blocks, which has the problem of low work efficiency; and the positioning blocks or wedge irons are easy to fall off during the flipping process, which has certain safety hazards in the operation;

[0005] In addition, the prior art also uses a U-shaped piece placed between the wing plate and the intermediate bearing seat. The setting of the U-shaped piece can facilitate the installation of the wing plate when the wing plate and the intermediate bearing seat are assembled, but the structural setting of the U-shaped piece is unreasonable. During the flipping process after the wing plate and the intermediate bearing seat are positioned and welded, there is still a problem that the wing plate is easily broken relative to the intermediate bearing seat under the action of gravity.

[0009] In the auxiliary device as described above, the main crossbeam can be placed on the top side of the wing plate and the intermediate bearing seat through a groove. The length of the groove is greater than the width of the top side of the wing plate, thereby ensuring the structural strength of the main crossbeam. In addition, the distance between the two fasteners is greater than half of the maximum width of the wing plate, thereby effectively confirming the position of the fasteners and effectively balancing the torque. This not only facilitates the assembly of the wing plate relative to the intermediate bearing seat, but also effectively offsets the gravity on the wing plate during the flipping process after the two are positioned, thereby avoiding the wing plate from breaking under the action of gravity.

[0010] The above-mentioned marine diesel engine base single-piece wing panel assembly and flipping safety auxiliary device, the main crossbeam is provided with at least four fasteners, wherein the first fastener and the second fastener are located on one side of the main crossbeam, the fourth fastener is located on the other side of the main crossbeam, and the middle section of the main crossbeam is also provided with a third fastener;

[0011] The side walls on both sides of the main cross beam are respectively and sequentially provided with a first fastener, a second fastener, a third fastener and a fourth fastener.

[0012] In the above-mentioned single-piece wing assembly and flipping safety auxiliary device for a marine diesel engine base, the distance between the first fastener and the second fastener is less than or equal to 120 mm, and the first fastener and the second fastener pass through the side wall of the main beam and abut against the wing.

[0015] In the above-mentioned single-piece wing plate assembly and flipping safety auxiliary device for a marine diesel engine base, the depth of the groove is greater than the depth of the top side groove of the wing plate;

[0016] The depth of the groove is 10-30 mm deeper than the depth of the groove on the top side of the wing plate.

[0017] The above-mentioned marine diesel engine base single-piece wing panel assembly and flipping safety auxiliary device, the side wall of the main cross beam is provided with a threaded hole, and the fastener is provided with an external thread structure to cooperate with the threaded hole;

[0023] The beneficial effects of the above utility model are as follows:

[0024] 1) The utility model provides an auxiliary device, and the main crossbeam can be placed on the top side of the wing plate and the intermediate bearing seat through a groove. The length of the groove is greater than the width of the top side of the wing plate, thereby ensuring the structural strength of the main crossbeam. In addition, the distance between the two fasteners is greater than half of the maximum width of the wing plate, thereby effectively confirming the position of the fasteners and effectively balancing the torque. This not only facilitates the assembly of the wing plate relative to the intermediate bearing seat, but also effectively offsets the gravity on the wing plate during the flipping process after the two are positioned, thereby avoiding the breakage of the wing plate under the action of gravity.

[0025] The movable fasteners are convenient for adjusting the positions of part or all of the fasteners according to the wing plate and the intermediate body bearing seat to ensure that the clamping force on the wing plate and the intermediate body is balanced.

[0026] 2) The auxiliary device provided in the utility model allows the main crossbeam to be placed in the intermediate bearing seat through the groove to position the wing plate, so that the auxiliary device can be used to quickly and safely adjust the position of the wing plate during the segmented assembly of the machine base, and prevent the safety hazards caused by the breakage of the wing plate positioning weld. During the welding process, the device is used for the first flipping before the base welding to strengthen the connection strength between the wing plate and the intermediate bearing seat, so as to avoid the cracking of the positioning weld between the wing plate and the intermediate bearing seat due to the impact during the flipping process and the inertia of the wing plate movement.

[0029] 5) The depth of the groove in the utility model is reasonably set and does not need to be set too deep. It is 10-30mm deeper than the depth of the groove on the top side of the wing plate. In this way, the main crossbeam mainly limits the length of the groove, and a relatively shallow depth can be beneficial to the assembly and flipping of the wing plate. There is no need for a too deep main crossbeam, which is beneficial to avoid waste of materials while ensuring operational safety.

[0030] 6) In the present invention, reinforcing components are provided at the threaded holes, which can enhance the strength of the main cross beam at each fastener and increase the service life of the entire auxiliary device. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The main crossbeam of the auxiliary device provided in this embodiment can be first placed on the intermediate bearing seat through the groove to position the wing plate, so that the auxiliary device can be used to quickly and safely adjust the position of the wing plate during the segmented assembly of the machine base, and prevent the safety hazard caused by the fracture of the wing plate positioning weld. The length of the groove is greater than the width of the top side of the wing plate, ensuring the structural strength of the main crossbeam, and the distance between the two fasteners is greater than half of the maximum width of the wing plate, which effectively confirms the position of the fasteners and effectively balances the torque.
