[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 An electrical construction equipment lifting device includes an H-shaped bracket. The H-shaped bracket includes a horizontal end 102 and two vertical ends 101. The two vertical ends 101 are symmetrically fixed on both sides of the horizontal end 102. The bottom of the horizontal end 102 rests on the top of the protective wall of the building. The two vertical ends 101 are located on both sides of the protective wall of the building. Alternatively, a fixed object with a rectangular top can be used to replace the protective wall of the building as the support part of the H-shaped bracket. The fixing position of the H-shaped bracket can be selected according to the construction environment of the building top. A fastening mechanism 2 is provided on the vertical end 101, and the fastening mechanism 2 is located below the horizontal end 102.

[0025] like Figure 1 and Figure 2 The top of the vertical end 101 is provided with a U-shaped groove 3. The inner surface of the U-shaped groove 3 is fixedly connected with a wear-resistant metal layer 301. The wear-resistant metal layer 301 is made of high-strength alloy steel or surface-hardened metal, which has high strength and excellent wear resistance, thus improving the service life of the equipment. The H-shaped bracket is provided with a support shaft 4, which can pass through the cable reel 100 to provide support for the cable reel 100.

[0026] Both ends of the support shaft 4 are located inside the U-shaped groove 3 to ensure the horizontality of the support shaft 4 and to provide support for the support shaft 4. Two limiting rings 5 ​​are fixedly connected to the outer surface of the support shaft 4. The two limiting rings 5 ​​are respectively attached to the side of the two vertical ends 101 that are close to each other, in order to restrict the lateral movement of the support shaft 4 and prevent the support shaft 4 from detaching from the H-shaped bracket.

[0027] like Figure 3 and Figure 4The fastening mechanism 2 includes a threaded rod 201, which is threadedly connected to the vertical end 101. The vertical end 101 has a threaded hole corresponding to the threaded rod 201. One end of the threaded rod 201, located below the horizontal end 102, is rotatably connected to a fastening pressure plate 202. The other end of the threaded rod 201, located outside the vertical end 101, is fixedly connected to a rotating disk 203, which allows the threaded rod 201 to rotate by manually controlling the rotating disk 203.

[0028] like Figure 3 and Figure 4 A transverse slide groove 6 is provided on the horizontal end 102. The transverse slide groove 6 can reduce the weight of the device and make it easier to carry. A transverse slider 7 is fixedly connected to the top of the fixing plate 202 by a round shaft. The transverse slider 7 and the transverse slide groove 6 are slidably connected to ensure the horizontal movement of the fixing plate 202 and prevent the fixing plate 202 from rotating.

[0029] like Figure 1 and Figure 2 A transverse groove 8 is provided on one side of the vertical end 101. The inner wall of the transverse groove 8 is bent upward to form an arc-shaped lifting groove 9. The arc-shaped lifting groove 9 is adapted to the support shaft 4. When carrying the device, the coil 100 is carried alone. At this time, the support shaft 4 can be moved from the transverse groove 8 into the arc-shaped lifting groove 9, so that the two limiting rings 5 ​​fit against the two sides of the two vertical ends 101. By manually pulling the support shaft 4 upward, the entire device can be lifted upward, which facilitates the carrying and transportation of the device.

[0030] like Figure 1 and Figure 2 Both vertical ends 101 are fixedly connected to concave reinforcing brackets 10 on the side away from each other, which improves the support strength of the vertical ends 101. The concave surface of the concave reinforcing bracket 10 and the opening of the transverse groove 8 are on the same side, which will not hinder the support shaft 4 from moving into the arc-shaped lifting groove 9.

[0031] like Figure 2 , Figure 3 and Figure 4 A fixing hole 11 is provided on the horizontal end 102, and an extension plate 12 is fixedly connected to both sides of the bottom of the vertical end 101. A fixing slot 13 is provided on the extension plate 12. The extension plate 12 is threaded to the external mechanism by passing a bolt through the fixing slot 13. The extension plate 12 and the H-shaped bracket can also be fixed.

[0032] The working principle of the electrical construction equipment lifting device provided by this utility model is as follows:

[0033] During electrical construction, when cable laying requires lifting the cable reel 100, the bottom of the horizontal end 102 is placed on top of the protective wall at the top of the building. Then, the rotating disc 203 is rotated clockwise. The rotating disc 203 drives the threaded rod 201 to rotate, causing the two locking plates 202 to press tightly against both sides of the protective wall at the top of the building, thus securing the H-shaped bracket.

[0034] Then, the support shaft 4 is passed through the cable reel 100, and both ends of the support shaft 4 are placed in the U-shaped groove 3 of the H-shaped bracket to support the support shaft 4 and the cable reel 100. When laying the cable, the cable reel 100 can rotate the support shaft 4 to release the cable during the process of pulling the cable.

[0035] After the cable laying is completed, remove the support shaft 4 and the cable reel 100 upwards, and then rotate the rotating disk 203 counterclockwise. The rotating disk 203 drives the threaded rod 201 to rotate, causing the two fixing plates 202 to separate from the wall. At this time, the H-type bracket can be removed.

[0036] Compared with related technologies, the electrical construction equipment lifting device provided by this utility model has the following beneficial effects:

[0037] This utility model uses a support shaft 4 to pass through the cable reel 100 and rest in the U-shaped groove 3 of the H-shaped bracket. The H-shaped bracket is placed above the protective wall on the top of the building. The fastening mechanism 2 fastens the H-shaped bracket above the protective wall on the top of the building, thereby fixing the H-shaped bracket and supporting the cable reel 100 for cable laying. Compared with mechanical cable laying brackets, the H-shaped bracket is more compact and lightweight, making it easier and less labor-intensive to transport to the top of the building. It is convenient to use the H-shaped bracket to support the cable reel 100 for cable laying during electrical construction on the top of the building.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
