[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a pole lifting device, which includes a lifting body 10, a lifting ring 20, and a limiting component 30. The lifting body 10 is used to fix the pole and is provided with a guide rail 111. The inner groove wall of the guide rail 111 is provided with a plurality of positioning holes 112. The end of the lifting ring 20 is slidably disposed in the guide rail 111 and can rotate in the guide rail 111. The limiting component 30 includes a first limiting member 31, which includes a first segment 311 and a second segment 312 connected to the first segment 311. The first segment 311 is rotatably connected to the lifting ring 20, and the second segment 312 is at least partially placed in the guide rail 111 and is used to be inserted into one of the positioning holes 112 to limit the lifting ring 20.

[0028] By setting a guide rail 111 on the hoisting body 10 and setting a positioning hole 112 on the inner groove wall of the guide rail 111, the pole column is fixed on the hoisting body 10 during hoisting. The end of the lifting ring 20 can slide or rotate in the guide rail 111. By setting a first limiting member 31, the first section 311 of the first limiting member 31 is rotatably connected to the lifting ring 20, and the second section 312 is at least partially placed in the guide rail 111 and inserted into one of the positioning holes 112. The hoisting angle can be adjusted by inserting the second section 312 into different positioning holes 112, and the lifting ring 20 can also be limited. This allows the pole column to be hoisted at a certain fixed hoisting angle, replacing the existing hoisting method of ordinary hooks, thereby effectively improving the stability and reliability of pole column hoisting.

[0029] In this embodiment, the hoisting body 10, the lifting ring 20, and the first limiting member 31 are all made of metal materials, preferably high-strength metal materials, including but not limited to carbon steel and alloy steel; the hoisting body 10 can be an integral structure or a welded structure.

[0030] Specifically, the hoisting body 10 includes an arc-shaped body 11 and a straight body 12. The straight body 12 is connected to the arc-shaped body 11. The arc-shaped body 11 is provided with a guide rail 111. The first limiting member 31 is located on the side of the lifting ring 20 close to the straight body 12. The arc-shaped body 11 is bent toward the side of the straight body 12 where the pole is fixed.

[0031] By setting up an arc-shaped body 11 and a straight body 12, the pole post is fixed on the straight body 12. The arc-shaped body 11 bends toward the side of the straight body 12 where the pole post is fixed. The lifting ring 20 slides on the guide rail 111 of the arc-shaped body 11. The first limiting member 31 restricts the movement of the lifting ring 20 toward the side closer to the straight body 12, thereby limiting the lifting ring 20.

[0032] Furthermore, guide rails 111 are provided on opposite sides of the arc-shaped body 11, and the two ends of the lifting ring 20 are slidably disposed on the corresponding guide rails 111. The two sides of the lifting ring 20 are slidably disposed in the corresponding guide rails 111. The positioning holes 112 on the inner groove walls of the two guide rails 111 are provided one-to-one. There are two second sections 312, and the two second sections 312 are partially placed in the two guide rails 111 and are both inserted into the corresponding positioning holes 112.

[0033] By providing guide rails 111 on both sides of the arc-shaped body 11 and corresponding positioning holes 112 on both sides, the smooth movement of the lifting ring 20 can be ensured, and the stability of the first limiting member 31 in the limiting position can also be guaranteed. In other embodiments, the guide rails 111 can also be provided in the middle of the arc-shaped body 11.

[0034] In this embodiment, both sides of the arc-shaped body 11 are provided with arc-shaped grooves as guide rails 111. The lifting ring 20 is U-shaped, and the end of the lifting ring 20 is cylindrical. The end of the lifting ring 20 is slidably disposed in the arc-shaped groove of the arc-shaped body 11 and can rotate in the arc-shaped groove. The cross-section of the arc-shaped body 11 is I-shaped. The first segment 311 of the first limiting member 31 is a straight rod with a circular cross-section. The two ends of the first segment 311 are respectively connected to a second segment 312, and the second segment 312 is an L-shaped rod with a circular cross-section. The bottom wall of the arc-shaped groove is provided with a positioning hole 112. The two second segments 312 of the first limiting member 31 are respectively placed in the two guide rails 111 and are inserted into the corresponding positioning hole 112. It can be understood that when the second segment 312 of the first limiting member 31 is deformed by force, it can be inserted into the positioning hole 112 or pulled out from the positioning hole 112.

[0035] Optionally, the straight body 12 includes a first mounting part 121, a straight section 122, and a second mounting part 123. One end of the straight section 122 is connected to the arc-shaped body 11 via the first mounting part 121, and the other end of the straight section 122 is connected to the second mounting part 123. The first mounting part 121 and the second mounting part 123 are used to fix the pole post. By providing the first mounting part 121 and the second mounting part 123 at both ends of the straight section 122, the first mounting part 121 and the second mounting part 123 respectively fix different positions of the pole post to ensure the stability of the pole post fixation.

[0036] Optionally, the first mounting part 121 is provided with a first mounting surface 1211, and the second mounting part 123 is provided with a second mounting surface 1231. Both the first mounting surface 1211 and the second mounting surface 1231 are used to fix the pole post. By providing corresponding mounting surfaces on the first mounting part 121 and the second mounting part 123, the accuracy of the pole post fixing position can be ensured.

[0037] In this embodiment, both the first mounting portion 121 and the second mounting portion 123 are cylindrical structures, and the cross-section of the straight section 122 is square. The axial directions of the first mounting portion 121 and the second mounting portion 123 are parallel and perpendicular to the extension direction of the straight section 122. The end faces of the first mounting portion 121 are flush with the two opposite planes of the straight section 122, and the end faces of the second mounting portion 123 are also flush with the two opposite planes of the straight section 122. The end face of the first mounting portion 121 near the arc-shaped body 11 is the first mounting plane 1211, and the end face of the second mounting portion 123 near the arc-shaped body 11 is the second mounting plane 1231.

[0038] The first mounting part 121 is provided with a first mounting hole 1212, and the second mounting part 123 is provided with a second mounting hole 1232. Both the first mounting hole 1212 and the second mounting hole 1232 are used for fasteners to pass through and fix the pole post. By providing corresponding mounting holes on the first mounting part 121 and the second mounting part 123, and using fasteners to fix the pole post, loosening at the connection between the pole post hanger and the pole post is prevented.

[0039] Optionally, the first mounting hole 1212 is a circular hole. In this embodiment, there are four first mounting holes 1212, which are arranged in pairs in a square pattern; the first mounting holes 1212 penetrate the first mounting portion 121 along the axial direction of the first mounting portion 121 and form corresponding openings on the first mounting plane 1211.

[0040] Optionally, the second mounting hole 1232 is an oblong hole. In this embodiment, two second mounting holes 1232 are provided at intervals. The second mounting hole 1232 passes through the second mounting portion 123 along the axial direction of the second mounting portion 123 and forms a corresponding opening on the second mounting plane 1231. The length direction of the second mounting hole 1232 is parallel to the extension direction of the straight section 122.

[0041] By setting the first mounting hole 1212 as a round hole and the second mounting hole 1232 as an oblong hole, the pole post can be accurately fixed using the fastener at the first mounting hole 1212. The position of the fastener at the second mounting hole 1232 can be adjusted adaptively, which is convenient for the staff to adjust the installation and can also adapt to the hole position requirements of different pole posts.

[0042] Furthermore, a first protective layer is provided on the first mounting plane 1211, and the first mounting plane 1211 contacts the pole post through the first protective layer. In this embodiment, a second protective layer is provided on the second mounting plane 1231, and the second mounting plane 1231 contacts the pole post through the second protective layer. By setting the corresponding protective layers, the lifting body 10 contacts the pole post through the protective layers, which can better protect the surface of the pole post.

[0043] Optionally, the first protective layer and / or the second protective layer are made of polyurethane, rubber, or plastic. In this embodiment, both the first and second protective layers are made of polyurethane. Polyurethane has high impact resistance and compressive strength, effectively buffering mechanical stress and preventing scratches or deformation of the electrode post. In other embodiments, materials with good elasticity and wear resistance, such as rubber or plastic (including but not limited to epoxy resin), can also be used for the first and second protective layers. The materials used for the first and second protective layers can be the same or different.

[0044] Optionally, the limiting assembly 30 also includes two second limiting members (not shown), which are detachably fixed to the arc-shaped body 11. One second limiting member is located between the lifting ring 20 and the first limiting member 31, and the other second limiting member is located on the side of the lifting ring 20 away from the first limiting member 31. The second limiting members are at least partially placed in the guide rail 111 to limit the end of the lifting ring 20 from sliding in the guide rail 111.

[0045] A second limiting member is added to the first limiting member 31 and fixed to the arc-shaped body 11. One second limiting member is located between the lifting ring 20 and the first limiting member 31, and the other second limiting member is located on the side of the lifting ring 20 away from the first limiting member 31. The second limiting member is placed at least partially inside the guide rail 111, thereby blocking the end of the lifting ring 20 from both sides to prevent the end of the lifting ring 20 from sliding and shifting inside the guide rail 111 during the lifting process. Even if the second section 312 of the first limiting member 31 deforms and detaches from its corresponding positioning hole 112, the second limiting member can still limit the lifting ring 20.

[0046] The second limiting component consists of a bolt and a nut. The bolt head is placed inside the first guide rail 111, and the nut is placed inside the second guide rail 111. The bolt tail passes through the positioning hole 112 of the guide rail 111 and is threadedly connected to the nut, thus fixing it to the arc-shaped body 11. The bolt head and nut are used to stop the end of the lifting ring 20 from being placed inside the corresponding guide rail 111. For the same guide rail 111, the second section 312 of the first limiting component 31 and the second limiting component are separately inserted into different positioning holes 112. In other embodiments, a second limiting component can also be provided and fixed to the guide rail 111, with part of the second limiting component placed inside the guide rail 111, thereby stopping the lifting ring 20 inside the guide rail 111.

[0047] The following is a detailed description of the use of the pole lifting device:

[0048] The staff first adjusts the appropriate angle and installs the lifting ring 20 and the first limiting piece 31 on the hoisting body 10. Then, the pole is fixed at the first mounting plane 1211 and the second mounting plane 1231 with bolts. The pole is then lifted by the hoisting device. The lifting ring 20 rotates in the guide rail 111 of the hoisting body 10, and the pole will naturally remain vertical. The pole can then be transferred using a transfer vehicle.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
