[0001] This utility model relates to the field of utility pole technology, and in particular to cement poles that facilitate the installation of power lines. Background Technology

[0002] Cement poles (also known as concrete poles) are columnar support structures made primarily of concrete. They are widely used in power transmission, communication lines, and lighting systems, mainly serving as supports for overhead lines.

[0003] In the current process of power line installation, it is usually necessary to first bury and fix the cement pole in the ground, and then workers use climbing tools to reach the top of the pole to install the mounting frame and the power line.

[0004] However, this operation has obvious problems: the risk to workers is high during high-altitude operations, and due to the narrow working space at the top of the pole, it is impossible to carry a large number of wires and installation equipment. They need to climb up and down multiple times, which is not only inefficient, but also increases the workload and safety hazards. Summary of the Invention

[0005] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0006] Therefore, one objective of this utility model is to provide a cement pole that facilitates the installation of electrical wires. By setting up a lifting component, the mounting frame and electrical wires can be pre-installed on the ground. Then, the component automatically lifts the mounting frame to the top of the pole and locks it, thereby avoiding workers working at heights and improving installation efficiency and safety.

[0007] To achieve the above objectives, the first aspect of this utility model provides a cement pole for easy installation of electrical wires, comprising: a pole body assembly, a lifting assembly, and a mounting frame. The pole body assembly includes a cement pole body and an inner sleeve, wherein the inner sleeve is fitted over the cement pole body from above and onto the inside of the cement pole body. The lifting assembly includes a counterweight, a first lifting rope, a connecting plate, a second lifting rope, and an assembly tube.

The connecting plate is fixedly mounted on the top end of the first lifting rope. The second lifting rope is fixedly mounted on the top end of the connecting plate. The top of the inner sleeve has a first through hole for the second lifting rope to pass through, and the top end of the second lifting rope extends through the first through hole to the outside of the inner sleeve. The assembly tube is slidably mounted on the outside of the cement pole body, and the top end of the assembly tube is connected to the top end of the second lifting rope. The mounting frame is mounted on the outside of the assembly tube.

[0008] In addition, the cement pole for facilitating the installation of power lines as described above according to this utility model may also have the following additional technical features: Specifically, the mounting frame includes a first frame and a second frame, wherein the first frame and the second frame are respectively fixedly installed on the left and right sides of the assembly tube, and the first frame and the second frame are fixedly connected by bolts and nuts.

[0009] Specifically, the top and inner side of the inner sleeve are provided with limiting components, the limiting components including a first guide wheel, a second guide wheel, a sealing cover and a guide rail, wherein the first guide wheel is fixedly installed on the inner side of the top of the inner sleeve; the second guide wheel is fixedly installed on the outer side of the top of the inner sleeve; the sealing cover is fixedly installed on the top of the inner sleeve; and the guide rail is fixedly installed on the inner side of the inner sleeve.

[0010] Specifically, the second suspension rope, supported and guided by the first guide wheel and the second guide wheel, does not contact the edge of the first perforation.

[0011] Specifically, the connecting plate is slidably connected to the guide rail, and a film is provided between the two to increase sliding damping.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] The following describes an embodiment of the wrought iron spray painting device with reference to the accompanying drawings.

[0019] like Figures 1-7 As shown, the cement pole for easy installation of power lines according to this utility model embodiment includes: pole body assembly 1, lifting assembly 2 and mounting frame 3.

[0020] The pole assembly 1 includes a cement pole 11 and an inner sleeve 12.

[0021] It should be noted that after the cement pole 11 is buried in the ground and the soil is backfilled and compacted, a chuck is used to attach it to the bottom of the cement pole 11 on the ground, and the chuck is fixed to the ground with ground nails to enhance the cement pole 11's ability to resist horizontal thrust.

[0022] The inner sleeve 12 is fitted onto the inside of the cement pole 11 from above.

[0023] The lifting assembly 2 includes a counterweight 21, a first lifting rope 22, a connecting plate 23, a second lifting rope 24, and an assembly tube 25.

[0024] The counterweight 21 is slidably installed on the inner side of the cement pole 11. The bottom end of the first lifting rope 22 is fixedly installed on the top of the counterweight 21. The connecting plate 23 is fixedly installed on the top of the first lifting rope 22. The second lifting rope 24 is fixedly installed on the top of the connecting plate 23. The top of the inner sleeve 12 has a first through hole for the second lifting rope 24 to pass through. The top of the second lifting rope 24 passes through the first through hole and extends to the outside of the inner sleeve 12. The assembly tube 25 is slidably installed on the outside of the cement pole 11. The top of the assembly tube 25 is connected to the top of the second lifting rope 24.

[0025] It should be noted that the cement rod 11 is a rod with equal diameter at the top and bottom, which is conducive to the stable sliding and rising of the assembly pipe 25 on its outer side.

[0026] It should be noted that a limiting baffle is fixedly connected to the top outer side of the inner sleeve 12, and a plug shaft is fixedly connected to the bottom end of the baffle. The top end of the assembly tube 25 is provided with a plug hole. When the assembly tube 25 is raised to the top, the top end of the assembly tube 25 is tightly fitted with the bottom end of the baffle, and the plug shaft is inserted into the plug hole, which limits the rising height of the assembly tube 25 and prevents the assembly tube 25 from rotating due to horizontal disturbance during use.

[0027] Mounting bracket 3 is installed on the outside of assembly tube 25.

[0028] It should be noted that after the cement pole 11 is installed and fixed, the initial position of the counterweight 21 is set in the middle of the cement pole 11. At this time, the assembly pipe 25 is suspended 20 cm above the ground by the second hoisting rope 24. Workers can directly install the mounting bracket 3 on the outside of the assembly pipe 25 on the ground and directly install the wire on the mounting bracket 3. After the installation is completed, the positioning of the counterweight 21 is removed, and the counterweight 21 slides down naturally, lifting the wire and the mounting bracket.

[0029] In addition, it should be noted that the weight of the counterweight 21 is much greater than the weight of the wire, the mounting bracket 3 and the assembly tube 25, and can easily lift the wire, the mounting bracket 3 and the assembly tube 25.

[0030] In one embodiment of this utility model, such as Figure 2 As shown, the mounting frame 3 includes a first frame 31 and a second frame 32.

[0031] The first frame 31 and the second frame 32 are respectively fixedly installed on the left and right sides of the assembly tube 25, and the first frame 31 and the second frame 32 are fixedly connected by bolts and nuts.

[0032] Specifically, when installing the mounting bracket 3 on the outside of the assembly tube 25, the first bracket 31 and the second bracket 32 ​​are surrounded on the outside of the assembly tube 25. The first bracket 31 and the second bracket 32 ​​are fixedly connected together by bolts and nuts. Then, the first bracket 31 and the second bracket 32 ​​are fixedly installed on the outside of the assembly tube 25 by bolts, thus completing the double installation and fixing of the mounting bracket 3. After that, the wires can be installed on the top of the first bracket 31 and the second bracket 32 ​​respectively.

[0033] In one embodiment of this utility model, such as Figure 5 and Figure 6 As shown, a positioning component 5 is provided on the outer side and bottom of the cement pole 11. The positioning component 5 includes a bolt 51, a positioning plate 52 and a self-locking mechanism 53.

[0034] Among them, the plug 51 is installed on both sides of the bottom of the cement pole 11, and the counterweight 21 has slots on both sides for the plug 51 to be inserted and positioned. It should be noted that positioning holes for inserting bolts 51 are provided on both sides of the cement pole 11. When the counterweight 21 is in the initial position, the bolts pass through the positioning holes and are inserted into the slots on both sides of the counterweight 21 to lock the initial height of the counterweight.

[0035] The positioning plate 52 is fixedly installed at the bottom of the cement pole 11, and the self-locking mechanism 53 is set at the top of the positioning plate 52.

[0036] It should be noted that the self-locking mechanism 53 includes a positioning block 531 and a spring 532. The positioning block 531 is slidably installed on the inner side of the storage groove at the top of the positioning plate 52. The spring 532 is disposed between the positioning block 531 and the storage groove, providing a supporting force for the positioning block 531 to slide out of the storage groove.

[0037] In addition, it should be noted that the top of the positioning block 531 is inclined on the side near the counterweight block 21, and the bottom outer side of the counterweight block 21 is provided with a positioning groove for the positioning block 531 to be inserted.

[0038] Specifically, when the bolts 51 installed on both sides of the cement pole 11 are removed at the same time, the counterweight 21 is not fixed and begins to slide down. As the bottom of the counterweight 21 contacts the inclined surface of the positioning block 531, the positioning block 531 compresses the spring 532 and retracts into the storage groove. When the bottom end of the counterweight 21 presses firmly against the top of the positioning plate 52, the positioning block 531 aligns with the positioning groove on the outer side of the bottom of the counterweight 21. The spring 532 pushes the positioning block 531 to slide into the positioning groove and lock the counterweight.

[0039] In one embodiment of this utility model, such as Figure 6 and Figure 7As shown, the top and inner side of the inner sleeve 12 are provided with a limiting component 4, which includes a first guide wheel 41, a second guide wheel 42, a sealing cover 43 and a guide rail 44.

[0040] The first guide wheel 41 is fixedly installed on the inner side of the top of the inner sleeve 12, the second guide wheel 42 is fixedly installed on the outer side of the top of the inner sleeve 12, the sealing cover 43 is fixedly installed on the top of the inner sleeve 12, and the guide rail 44 is fixedly installed on the inner side of the inner sleeve 12.

[0041] It should be noted that both the first guide wheel 41 and the second guide wheel 42 are vertically arranged, and the edge partitions of the first guide wheel 41 and the second guide wheel 42 extend beyond the second hoisting rope 24, effectively guiding the second hoisting rope 24 to move vertically and preventing the second hoisting rope 24 from detaching from the first guide wheel 41 and the second guide wheel 42 during movement.

[0042] The second suspension rope 24, supported and guided by the first guide wheel 41 and the second guide wheel 42, does not contact the edge of the first perforation.

[0043] The connecting plate 23 is slidably connected to the guide rail 44, and a film is provided between the two to increase the sliding damping.

[0044] Specifically, when the counterweight 21 slides down, it drives the connecting plate 23 to slide down within the guide rail 44 via the first suspension rope 22. Due to the effect of the film, the friction between the connecting plate 23 and the guide rail 44 is increased, making... The connecting plate 23 slides down steadily and at a constant speed within the guide rail 44. The connecting plate 23 drives the assembly tube 25 to rise at a constant speed on the outside of the cement pole 11 via the second hoisting rope 24, lifting the mounting bracket 3 and the wires on the outside of the assembly tube 25 to the top of the cement pole 11. When the top of the assembly tube 25 is tightly attached to the bottom of the baffle, the insertion hole at the top of the assembly tube 25 is penetrated and inserted by the insertion shaft of the baffle, and the counterweight 21 is locked by the self-locking mechanism 53, the mounting bracket 3 and the wires are lifted and hoisted.

[0045] In summary, the cement pole for easy installation of electrical wires of this utility model has a structure on the inner side of the cement pole body 11 that allows the assembly pipe 25 to be quickly lifted by the natural fall of the counterweight block 21. This moves the work that originally required workers to climb high to assemble the mounting frame and electrical wires to be completed on the ground in advance, replacing the high-altitude work of workers, improving the safety of the installation work, and the working area on the ground is wider than the working area at the top of the cement pole, which can realize the cooperation of multiple workers to install, improve the assembly efficiency of the mounting frame 3 and electrical wires, and shorten the operation time.
