Description

Technical Field

[0001] This utility model relates to the field of protection technology for the lifting and overturning of marine engine bases and frames, and in particular to a corner protection device for overturning marine engine bases and frames. Background Technology

[0002] The engine base and frame of a marine engine require eight flipping operations during the welding process. During flipping and hoisting, the wire rope is tightly attached to the top and bottom plates. When the engine is lifted, there is a great deal of pressure between the wire rope and the steel plate. This force can have a serious impact on the steel plate and the wire rope, which may cause the surface of the steel plate to deform and crack under pressure, or cause the wire rope to be partially or completely cut, posing a very serious safety hazard.

[0003] Currently, the common solution to this problem is to add corner protectors between the steel plate and the wire rope. However, existing corner protectors often require repeated welding and cutting during installation, and their fixed positions make them difficult to adjust and lack flexibility.

[0007] Furthermore, the positioning plate is a hinge plate; the rotating shaft is a cylindrical hinge shaft.

[0008] Furthermore, a strip-shaped protrusion is provided in the middle of the upper surface of the positioning plate along the extension direction.

[0009] Furthermore, the length of the corner protector is 450~550mm and the thickness is 4~6mm.

[0016] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] It should be noted that in the description of this utility model, the terms "upper", "lower", "top", "bottom", "one side", "the other side", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not mean that the device or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0018] See appendix Figures 1-3 The present invention proposes a corner protection device for flipping a marine engine base frame, comprising a rotating shaft 1, a positioning plate 2, a strong magnet 3, and an arc-shaped guard plate 4.

[0019] The positioning plate 2 has evenly distributed circular grooves on its surface; the strong magnets 3 are embedded in the circular grooves one by one; the front long side of the positioning plate 2 is rotatably connected to the upper long side of the arc-shaped guard plate through the rotating shaft 1.

[0020] In this embodiment, the positioning plate 2 can be a hinge piece, the rotating shaft can be a cylindrical hinge shaft, the positioning plate 2 and the rotating shaft 1 together form a hinge structure, and the arc-shaped guard plate 4 is fixedly connected to one side of the hinge shaft as a whole by welding.

[0021] Both the positioning plate 2 and the arc-shaped guard plate 4 are metal plates.

[0022] The upper surface of the positioning plate 2 has a strip-shaped protrusion 21 extending in the middle direction.

[0023] The length of the corner protector is generally set to 450~550mm, and the thickness is set to 4~6mm.

[0024] The usage process of this utility model is as follows:

[0025] 1. Preparation stage

[0026] First, determine the horizontal and vertical positions of the corner protector on the surface of the steel plate 5 based on the position of the lifting lugs, the length of the wire rope, and the process being performed. Then, attach one side of the positioning plate 2 to the surface of the steel plate 5 using a strong magnet 3, and slowly lower the other side until it is completely attached to the surface of the steel plate 5. Adjust the corner protector to the calculated position so that the inner circle of its curved guard plate 4 naturally contacts the corners of the upper and lower edges of the steel plate.

[0027] 2. Tilting and hoisting

[0028] According to the process, the wire ropes are hung on the corresponding lifting lugs, and the hooks are used to straighten the wire ropes to ensure they are in the position of the corner protection device. After lifting, the inner and outer sides of the arc-shaped guard plate 4 contact the workpiece steel plate 5 and the wire rope respectively to ensure safety during production. After the flipping and lifting is completed, the arc-shaped guard plate 4 is flipped counterclockwise and placed on the strip protrusion on the surface of the longer hinge piece 2. Under the magnetic force of the strong magnet 3, it is ensured that it will not flip due to accidental contact. During the next flipping and lifting, it is flipped clockwise and placed on the corner, and the above operation is repeated.

[0029] 3. Recycling after completion

[0030] After all the flipping and hoisting work is completed, while the corner protector is in working condition, slowly pull the corner protector from the side of the steel plate 5 until it leaves the surface of the steel plate 5. Check whether the corner protector is damaged after flipping and hoisting, and then classify and store it for reuse.

[0031] This invention can be placed on the top and bottom plates of the machine base frame, abandoning the traditional welding fixing method. Fixation is achieved through an array of neodymium iron boron magnets 3, saving time in preparation for tilting and hoisting. During tilting and hoisting, the arc-shaped protective plate 4 is lowered clockwise, allowing the wire rope to contact and press against it, protecting the wire rope and the top and bottom plates of the frame. After tilting and hoisting is completed and welding is in preparation, the arc-shaped protective plate 4 is retracted counterclockwise, providing ample space for side plate welding without affecting construction. The strip-shaped protrusion 21 ensures that the arc-shaped protective plate 4 does not contact the strong magnets 3 when retracted, and is also protected by the magnetic force of the strong magnets 3, preventing tilting due to contact.

[0032] This invention can effectively protect the machine base and frame, ensure safety in the tilting and hoisting process, prevent economic losses and repair work caused by friction between the wire rope and the steel plate, and help ensure that the production plan is completed on time.
