[0001] This utility model relates to the field of fixing device technology, and in particular to an adjustable fixing device for transportation and hoisting. Background Technology
[0002] In the transportation and hoisting of large components, traditional binding and hoisting methods are prone to surface damage and loss of control due to center of gravity shift, especially in the hoisting of precision equipment or irregularly shaped structures where the risks are even higher. In recent years, the combination technology of integrated lugs and hoisting fixing devices has become an industry trend: lugs, as standardized lifting points and fixing interfaces, can be quickly connected to modular fixing devices, reducing local stress concentration through force distribution design, and are combined with intelligent sensors to monitor the hoisting status. This technology significantly improves hoisting safety and efficiency, while reducing human error, and is suitable for high-precision engineering needs in complex working conditions.
[0003] In the prior art, lifting lugs are mostly molded in one piece during production, which means that they cannot be adjusted according to different installation objects during use, resulting in poor versatility and thus narrowing the scope of application of the lifting lugs. At the same time, it also increases the installation cost during use. Based on this, this utility model is proposed. Utility Model Content

DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0025] In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.
[0026] Embodiment 1: refer to Figures 1-5 An adjustable fixing device for transportation and hoisting, comprising mounting bottom plates 1 fixed on both sides of goods, further comprising: the mounting bottom plates 1 are fixedly connected with sliding rails 11, the sliding rails 11 are slidably connected with support plates 2, and fixing holes 113 are formed in the mounting bottom plates 1; the support plates 2 are fixedly connected with cylindrical bosses 22, and the cylindrical bosses 22 are slidably connected with lifting lugs 3; the lifting lugs 3 and the cylindrical bosses 22 jointly clamp and limit the sling, and when the two support plates 2 slide, the angle of inclination of the sling when hoisting the goods changes.
[0027] In this utility model, a fixing hole 113 is provided on the mounting base plate 1. The mounting base plate 1 is fixedly connected to the shelf or the cargo body by welding or plugging through the fixing hole 113, thereby completing the fixation of the entire device. The lifting lug 3 and the cylindrical boss 22 together clamp and position the hook lock wrapped around the lifting lug 3. The lifting lug 3 can slide on the cylindrical boss 22, thereby changing the distance between the lifting lug 3 and the cylindrical boss 22, so as to be suitable for lifting cables of different thicknesses.
[0028] By sliding the support plate 2, the cylindrical boss 22 and the lifting lug 3 can be moved vertically within a small range, thereby changing the position of the lifting lug 3 on both sides. Thus, without changing the length of the sling, when the lifting lug 3 is pulled, the cargo itself can be tilted horizontally, which can cope with sloping ground and irregularly shaped parts with an unstable center of gravity.
[0029] Example 2: Refer to Figures 1-5 Similar to Embodiment 1, but with a further improvement: a limiting rod 221 is fixedly connected to the cylindrical boss 22; a limiting groove 31 is provided on the lifting lug 3; the lifting lug 3 is slidably connected to the limiting rod 221 through the limiting groove 31; an adjusting bolt 35 is rotatably connected to the lifting lug 3; the adjusting bolt 35 is connected to the cylindrical boss 22 by threads; a connecting rod 32 is fixedly connected to the lifting lug 3; a positioning plate 33 is fixedly connected to the other end of the connecting rod 32; a sliding groove 222 is provided on the cylindrical boss 22; and the sliding groove 222 is connected to the connecting rod 32. Corresponding to the position, the positioning plate 33 has multiple sets of mounting holes 331. The positioning plate 33 is fixedly connected to the base 4 through the mounting holes 331. The base 4 is slidably connected to the sliding rod 41. The sliding rod 41 is connected to the base 4 by a tension spring 42. The sliding rod 41 is rotatably connected to the hook 43. The lifting lug 3 is rotatably connected to the buckle 3. The buckle 34 is engaged with the lifting lug 3. The support plate 2 is provided with insertion holes 21 and positioning holes 23 respectively. The sliding track 11 is provided with auxiliary through holes 111 and insertion holes 112 respectively.
[0030] In this utility model, the cylindrical boss 22 and the lifting lug 3 are slidably connected by a limiting rod 221 and a limiting groove 31. This method can restrict the rotation of the lifting lug 3. By rotating the adjusting bolt 35, the lifting lug 3 can be slid on the cylindrical boss 22, thereby adjusting the distance between the lifting lug 3 and the cylindrical boss 22.
[0031] The positioning plate 33 has multiple sets of mounting holes 331. Preferably, the mounting holes 331 are threaded. The base 4 is installed and fixed to the mounting holes 331 by bolts. Users can install multiple bases 4 as needed. The tension spring 42 pulls the sliding rod 41 to keep it moving downward, so that the hook 43 and the buckle 34 can always be engaged in the case of external human interference. When the hook 43 and the buckle 34 are engaged, the hook lock can be effectively prevented from slipping off the lifting lug 3. The positioning plate 33 is fixedly connected to the lifting lug 3 by the connecting rod 32, so that the lifting lug 3 can drive the positioning plate 33 to move synchronously when it moves, thereby ensuring that the hook 43 and the buckle 34 are always engaged.
[0032] A bolt rod can be inserted into the insertion hole 112 on the side of the sliding rail 11 and the insertion hole 21 on the support plate 2 to complete the positioning of the support plate 2. At the same time, the positioning hole 23 is threaded, and the bolt is connected to the positioning hole 23 after passing through the auxiliary through hole 111 to complete the auxiliary positioning of the support plate 2.
[0033] When using the crane, the user first fixes the mounting base plate 1 to the shelf or goods, slides the support plate 2 to the appropriate position and then fixes the support plate 2. Then, the user rotates the adjusting bolt 35 to adjust the distance between the lifting lug 3 and the cylindrical boss 22, and puts on the rope. Finally, the user fastens the buckle 34 to the hook 43 and then starts the crane to transport the goods.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
