[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0020] like Figure 1-5 As shown, the crane winch splicing structure of the embodiment includes two sets of winch units 1 that are spliced ​​together to form a complete winch. The two sets of winch units 1 are fixedly connected by a connecting component. Each winch unit 1 includes several radially arranged limiting rods 2. Each limiting rod 2 is provided with a fixing hole 21. The connecting component includes a fixing disc 3 and a fixing bolt 4. The fixing bolt 4 passes through the fixing hole 21 and is fixedly connected to the fixing disc 3.

[0021] This design facilitates transportation and installation, and reduces operational difficulty: the complete winch is divided into two sets of interlocking winch units. Compared with a large, integrated winch, the weight and size of a single unit are significantly reduced, making it easier to handle and hoist. Especially in the assembly of large cranes, it reduces the requirements for handling equipment and simplifies the installation process.

[0022] According to one embodiment of the present invention, at least two fixing holes 21 are provided radially.

[0023] This design enhances connection stability and reduces structural sway. At least two radially distributed fixing holes allow fixing bolts to secure the limiting rod from multiple radial points. Compared to single-point fixing, multi-point constraint can significantly limit the radial displacement and circumferential rotation of components, preventing swaying caused by vibration and traction load during winch operation, and ensuring a more stable connection between the spliced ​​winch unit and the fixed disc.

[0024] According to one embodiment of the present invention, the limiting rod 2 further includes a connecting rod 5 located at the semi-circular bottom of the winch unit 1. The connecting rod 5 is provided with a fixing through hole 51, the axis of which is perpendicular to the axis of the fixing disc 3. A wear-resistant layer 52 is fixedly provided at the end of the fixing through hole 51. The connecting assembly further includes a fixing bolt 4, which passes through the fixing through holes 51 of the two sets of connecting rods 5 of the keyboard unit.

[0025] This design specifically strengthens the bottom support of the winch unit, improving the stability of the splicing. The inserted fixing bolts can form a "lateral constraint" on the bottom of the two sets of winch units from the direction perpendicular to the disc, preventing the bottom from being misaligned or loosened due to vibration or force during winch operation, making the splicing of the two sets of units tighter and the overall deformation resistance stronger.

[0026] According to one embodiment of the present invention, the fixed disc 3 is provided with an elongated through hole 31, which is arranged adjacent to the fixing through hole 21 of the connecting rod 5.

[0027] This design resolves assembly alignment errors and reduces installation difficulty.

[0028] According to one embodiment of the present invention, the winch unit 1 further includes a bearing ring 6 fixedly disposed between the two limiting rods 2.

[0029] With this design, the steel cable is initially wound around the bearing ring, providing a foundation for the winding of the steel cable; the bearing ring is also equipped with clamps for fixing the steel cable thereon.

[0030] According to one embodiment of the present invention, the limiting rod 2 is provided with a bearing through hole 53, which is located on the side away from the center of the fixing through hole 21; it also includes a bearing bolt 54 passing through the bearing through hole 53, and the bearing ring 6 is fixedly connected to the bearing bolt 54.

[0031] This design avoids interference from the fixing bolts on the winding of the steel cable.

[0032] According to one embodiment of the present invention, a double-hole gasket 55 is also included, which is disposed against the side wall of the connecting rod 5.

[0033] This design disperses bolt pressure, preventing deformation and damage to the sidewalls of the connecting rod; it also enhances connection sealing and anti-loosening effects.

[0034] According to one embodiment of the present invention, the double-hole gasket 55 is provided with a folded edge 551 for covering and limiting the two sets of connecting rods 5.

[0035] This design precisely limits the two sets of connecting rods, preventing relative displacement; it also enhances the integrity of the gasket and connecting rods, improving the anti-loosening effect.

[0036] According to one embodiment of the present invention, at least one set of the winch units 1 is provided with a protrusion 7 for easy gripping and operation.

[0037] This design provides a clear point of force application, reducing the difficulty of moving the winch unit.

[0038] According to one embodiment of the present invention, the limiting rod 2 is provided with a weight-reducing drainage cavity 22.

[0039] This design reduces weight without sacrificing strength, lowers the overall load and operational difficulty, drains accumulated water and impurities, reduces the risk of rust during outdoor operations, extends service life, and meets the long-term use requirements of harsh outdoor environments.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
