DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0028] Combination Figure 1 The utility model is a wire rope wedge sleeve clamp, comprising a connecting sleeve 1 for lifting the wire rope and a clamping mechanism 2 assembled on the outside for fixing the connecting sleeve 1;

[0029] The clamping mechanism 2 includes a clamping arm 21 and a clamping groove 211 provided on the inner wall thereof for limiting and fixing the edge of the connecting sleeve 1. Two sets of pressing plates 22 and fixing bolts 221 for connecting the two sets of pressing plates 22 are provided at the bottom end of the clamping arm 21. A mounting hole 23 is provided above the clamping arm 21.

[0030] The opening of the mounting hole 23 is provided with a lifting ear 25, and the bottom of the lifting ear 25 is provided with a locking component 26 located inside the mounting hole 23 and used to lock the lifting ear 25.

[0031] First, the wedge sleeve refers to the connecting sleeve 1, and the connecting sleeve 1 is clamped into the clamping groove 211 by the clamping arm 21. The function of the clamping groove 211 is to prevent the connecting sleeve 1 from axial movement. Then, the entire connecting sleeve 1 is fixed by two sets of pressure plates 22 at the bottom of the clamping arm 21 and the fixing bolts 211. The purpose is to prevent the radial movement of the connecting sleeve 1. When the wire rope is hoisted, the clamp clamps the wedge sleeve and the center of gravity of the wire rope is always consistent, which effectively solves the problem of getting stuck. Compared with the prior art, the utility model patent effectively solves the problem of getting stuck by using a wedge sleeve clamp, making the installation of the wedge sleeve easier, reducing labor, and improving work efficiency.

[0032] Secondly, the lifting ear 26 installed on the mounting hole 23 can be rotated left and right one hundred and eighty degrees, and the locking assembly 26 is used to lock the lifting ear 26. This is because during the lifting process of the wire rope, it is not necessarily vertical lifting. During this period, there may be a certain angle difference between the lifting device and the wire rope. The rotatable lifting ear 26 can be more conducive to maintaining the stability of the wedge sleeve during the lifting process.

[0033] The utility model is further described below in conjunction with embodiments.

[0034] Combination Figure 2 and Figure 5 In this embodiment, a sliding groove 24 is provided on the inner wall of the mounting hole 23, a first ring 251 and a second ring 252 are fixedly provided on the bottom end of the lifting ear 25, and a notch is provided on the second ring 252;

[0035] Furthermore, the first ring 251 and the second ring 252 are respectively arranged at the front and rear ends of the mounting hole 23, and the structures of the two are slightly different.

[0036] In this embodiment, the locking assembly 26 includes a latch 261 fixedly connected to the first collar 251, a bearing 262 is sleeved on the outer periphery of the latch 261 to enable it to be rotatably connected to the mounting hole 23, and a plurality of groups of insertion holes 2611 surrounding the central axis are formed on the surface of the end of the latch 261;

[0037] Furthermore, the latch pin 261 is rotatably connected to the mounting hole 23 via the bearing 262 , and since the first ring 251 at the lower end of the lifting ear 25 is fixedly connected to the latch pin 261 , the lifting ear 25 can rotate in the mounting hole 23 .

[0038] In this embodiment, one end of the latch 261 is equipped with a movable rod 263, a spring 264 is sleeved on the outer periphery of the movable rod 263, and one end of the movable rod 263 is provided with a gasket 265 located inside the mounting hole 23;

[0039] Furthermore, the movable rod 263 can move forward and backward inside the mounting hole 23 , and the spring 264 cooperates with the gasket 265 to reset the movable rod 263 .

[0040] In this embodiment, a push rod 266 is movably provided at the tail end of the movable rod 263, and a limit plate 267 is fixedly provided at the end of the movable rod 263;

[0041] Furthermore, a lever and fulcrum structure is formed between the push rod 266 and the gasket 265. By pressing the push rod 266, the limit plate 267 can be lifted. At the same time, the movable rod 263 moves inside the mounting hole 23 and disengages from the latch 261, so that the latch 261 can rotate inside the mounting hole 23. During this process, the spring 264 is compressed. As the push rod 266 is released, the compressed spring 264 is released and the movable rod 263 is reset and reconnected with the latch 261, so that the latch 261 is locked, thereby fixing the position of the lifting ear.

[0042] In this embodiment, the front end of the movable rod 263 is provided with a sliding sheet 2631 sliding inside the sliding groove 24, and the front end of the movable rod 263 is also provided with two groups of plug rods 2632 matching the plug holes 2611;

[0043] Furthermore, the movable rod 263 and the sliding slot 24 are mutually limited, so that when the movable rod 263 and the latch 261 are connected to the insertion hole 2611 through the insertion rod 2632, the latch 261 cannot rotate.

[0044] In this embodiment, the connecting sleeve 1 includes a rope body 11 passing through the interior thereof, and a fixing member 12 for fixing the rope body 11;

[0045] Furthermore, the rope body 11 can be fixed by the fixing member 12 after passing through the connecting sleeve 1 .

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
