Description
Technical Field
[0001] This utility model belongs to the field of lifting fixture technology, specifically relating to a hydraulic shaft lifting fixture. Background Technology
[0002] In actual production processes, lifting equipment is used. Existing lifting equipment mostly uses steel wire ropes to directly fix the lifting frame, and the lifting hook on the lifting frame hooks the items to complete the lifting work. However, in actual use, due to the uncertainty of the environment, such as limited space, it is necessary to adjust the length of the lifting fixture, so the traditional lifting fixture is no longer suitable.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0020] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.
[0022] This utility model provides, for example Figure 1-3 The hydraulic shaft lifting fixture shown includes
[0023] The lifting frame 1 is configured as a mounting bracket for the clamping part 4. It has a cross structure and 4-6 clamping parts 4 are fixed at the bottom by bolts. The clamping part 4 can be a mechanical claw for gripping objects.
[0024] The lifting column 2 is a column-shaped structure. One end of it is fixed at the overlapping position of the cross structure of the lifting frame 1, and the other end is set as a ring structure, which is fixed relative to the lifting column 2.
[0025] The linkage mechanism 3 has one end detachably connected to the ring structure of the lifting column 2, and the other end connected to the lifting rope 37, which can be made of steel wire rope. Specifically, the linkage mechanism 3 includes a lower lifting part 31 and an upper lifting part 34, which are connected by a connecting end 33 and can rotate relative to the connecting end 33.
[0026] The lower lifting part 31 is a columnar structure, with one end set as a lifting hook and the other end surface set with a threaded part 32. The upper lifting part 34 is also a columnar structure, with one end set as a lifting ring 36 and the other end surface set with a threaded part 35, and the lifting ring 36 is set away from the threaded part 32.
[0027] The connecting end 33 includes two mounting rings 331. The interior of the two mounting rings 331 is respectively provided with internal threads that match the threaded part 32 and the threaded part 35. The two mounting rings 331 are connected by three connecting plates 332. The two ends of the connection of the three connecting plates 332 are fixed to the outside of the mounting rings 331, thus forming a cylindrical space between the mounting rings 331. The lower lifting part 31 and the upper lifting part 34 can move in this cylindrical space, and their positions can be adjusted by rotating the lower lifting part 31 and the upper lifting part 34.
[0028] During use, the hydraulic shaft lifting fixture grabs the object through the clamping part 4, and then drives the linkage mechanism 3 through the lifting rope 37, thereby moving the lifting frame 1 to complete the lifting work. In this process, if it is necessary to adjust the lifting length, or adjust the length of the linkage mechanism 3 according to the site environment, it can be done by rotating the lower lifting part 31 and the upper lifting part 34, which is convenient and practical.
