The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The following is combined Figures 1 to 4 This invention describes a lifting device for mixed-tower anchor cables provided in an embodiment of the present invention. It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any particular limitation on the present invention.

[0027] An embodiment of this utility model provides a lifting tool for mixed tower anchor cables, such as... Figures 1 to 3 As shown, it includes: a clamp 100 for clamping the mixed tower anchor cable; and multiple inner lining pads 200, each inner lining pad having a different thickness and all adapted to the clamp 100, with one of the multiple inner lining pads 200 being placed on the inner side of the clamp 100.

[0028] The lifting tool for mixed-tower anchor cables provided by this utility model includes a clamp 100 and multiple inner lining pads 200. The clamp 100 is used to clamp the mixed-tower anchor cables. The multiple inner lining pads 200 have different thicknesses, and each inner lining pad 200 can be adapted to the clamp 100. When lifting the anchor cables, an inner lining pad 200 of appropriate thickness can be selected and placed inside the clamp 100 according to actual needs. Through this structural design, the versatility of the lifting tool for mixed-tower anchor cables can be greatly improved.

[0029] In one embodiment of this utility model, the inner liner 200 is a rubber pad. Furthermore, the inner liner 200 should completely cover the contact area between the clamp 100 and the anchor cable to avoid frictional damage to the anchor cable caused by the clamp 100.

[0030] The inner liner 200 can be made of a rubber material with high elasticity, wear resistance and good insulation properties. It has a certain thickness to provide effective protection for the anchor cable. At the same time, the inner liner 200 has anti-slip texture, which increases the friction with the surface of the anchor cable and prevents the anchor cable from sliding during hoisting. This avoids damage to the surface of the anchor cable caused by direct friction with metal parts during hoisting.

[0031] In one embodiment of the present invention, the clamp 100 includes: a first U-shaped clamp 110; and a second U-shaped clamp 120, wherein the second U-shaped clamp 120 is connected to the first U-shaped clamp 110.

[0032] In another embodiment of this utility model, the clamp 100 further includes a clamp 300, which is connected between the first U-shaped clamp 110 and the second U-shaped clamp 120. The clamp 300 can be a steel clamp 300.

[0033] For example, the inner liner 200 includes a first half-liner and a second half-liner. During use, an inner liner 200 of appropriate thickness is first selected based on the actual working conditions. The first half-liner 200 is placed inside the first U-shaped clamp 110, and the second half-liner is placed inside the second U-shaped clamp 120. The first U-shaped clamp 110 and the second U-shaped clamp 120 are then connected to clamp the tower anchor cable, and finally, a clamp 300 is used to lock the first U-shaped clamp 110 and the second U-shaped clamp 120 together.

[0034] The first U-shaped clamp 110 and the second U-shaped clamp 120 are connected to each other to encircle and clamp the anchor cable. At the same time, the clamping length of the clamping cylinder 100 is not less than 2m to ensure the stability of the anchor cable during hoisting.

[0035] In one embodiment of this utility model, the first U-shaped clamp 110 and the second U-shaped clamp 120 are mated together to form a conical locking surface, and the clamp 300 is locked to the conical locking surface. For example, the inclination angle of the conical surface can be set to 92°.

[0036] like Figure 1 and Figure 2 As shown, the first U-shaped clamp 110 and the second U-shaped clamp 120 are aligned and can form a conical locking surface. It is important to emphasize that the conical locking surface is an inverted conical locking surface; that is, when hoisting from bottom to top, the upper diameter of the conical locking surface is larger than the lower diameter. With this structural design, the clamp 300 is locked onto the conical locking surface. Due to the limiting effect of the conical surface, the clamp 300 can be prevented from slipping, and its locking effect is more reliable.

[0037] In one embodiment of the present invention, the clamp 300 includes: a clamp body 310, on which a locking notch is formed; a connecting ear 320, which is disposed at the locking notch; and a connector, which is locked to the connecting ear 320.

[0038] Furthermore, in one embodiment of the present invention, a conical locking cavity is formed on the inner side of the hoop 310, and the conical locking cavity is adapted to the conical locking surface.

[0039] For example, such as Figures 1 to 3 As shown, a locking notch is formed on the hoop 310, and a connecting lug 320 is provided at the location of the locking notch. A connecting piece is connected to the connecting lug 320. During use, firstly, an inner liner 200 of appropriate thickness is selected based on the actual working conditions. The inner liner 200 is placed on the inner side of the first U-shaped clamp 110 and the second U-shaped frame. The first U-shaped clamp 110 and the second U-shaped clamp 120 are then connected to clamp the anchor cable of the tower. Finally, the clamp 300 is fitted onto the outer side of the first U-shaped clamp 110 and the second U-shaped clamp 120, and moved to a suitable height position so that the cavity surface of the conical locking cavity of the clamp 300 fits as closely as possible to the conical locking surface. Finally, the connecting lug 320 is locked in place using the connecting piece. For example, as... Figure 4 As shown, the connector can be a connecting bolt, and multiple connecting bolts can be connected to the connecting lug 320.

[0040] In one embodiment of this utility model, there are two locking notches, which are symmetrically arranged with the central axis of the hoop 310 as the axis of symmetry; each locking notch is provided with a connecting ear 320, and each connecting ear 320 is locked with a connecting piece.

[0041] To improve the stress state of the clamp 300 and enhance the locking fit between the conical locking cavity of the clamp 300 and the conical locking surface of the clamp 100, two locking notches can be symmetrically provided on the clamp body 310. In other words, the clamp body 310 is designed as a symmetrical split structure. Each locking notch is provided with a connecting lug 320, which is locked in place by a connector.

[0042] In one embodiment of the present invention, the clamp 300 further includes a lifting lug 400, which is disposed on the clamp body 310.

[0043] Furthermore, in one embodiment of this utility model, the lifting lug 400 includes: a first lug plate disposed on the hoop 310; and a second lug plate disposed on the hoop 310, wherein the second lug plate and the first lug plate are symmetrically arranged about the central axis of the hoop 310. The first and second lug plates are symmetrically welded to both sides of the hoop 310, forming an integral structure with the hoop 310. The lifting lug 400 can be made of high-strength alloy steel of the same material as the hoop 310, and connected by a special welding process to ensure that the strength of the welded part is not lower than that of the base material. The first and second lug plates are flat, with a square through hole in the middle, the size of which matches common lifting ropes or hooks. This design facilitates connection with various lifting equipment to realize the lifting operation of the clamp 100 and the anchor cable it holds.

[0044] During use, firstly, select a rubber liner 200 of appropriate thickness based on the diameter of the anchor cable to be hoisted. Place the rubber liner 200 between the anchor cable and the clamp 100, ensuring that the rubber liner 200 completely covers the area where friction or collision may occur. Then, connect the first U-shaped clamp 110 and the second U-shaped clamp 120 to fit over the anchor cable, and install the steel clamp 300. Adjust the position of the clamp 300 so that the clamp 100 can tightly grip the anchor cable.

[0045] Next, use lifting ropes or hooks to pass through the square perforations on the lifting lug 400 to reliably connect the lifting sling to the lifting equipment. During the connection process, ensure that the ropes or hooks are securely connected to the lifting lug 400 without any signs of loosening. Start the lifting equipment and slowly raise the lifting sling to begin lifting the anchor cable. During the lifting process, closely monitor the anchor cable to ensure its stability and prevent any swaying or slippage. Once the designated position is reached, slowly lower the lifting sling to precisely place the anchor cable at the predetermined location.

[0046] After the hoisting is completed, first remove the hoisting rope or hook from the lifting lug 400, then loosen the connecting bolts of the steel clamp 300, remove the clamp 100, and finally remove the inner liner 200 to complete the disassembly of the lifting equipment.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
