Description

Technical Field

[0001] The present invention relates to the technical field of cement utility poles, in particular to a spliced ​​cement utility pole and an assembling method thereof. Background Art

[0002] In the construction of infrastructure such as electricity and communications, cement utility poles serve as key structures for supporting cables. Their installation stability and construction convenience directly affect the quality and efficiency of the project. Traditional cement utility poles are mostly integrally cast structures, which have problems such as transportation difficulties and the need for large lifting equipment during installation. In particular, their construction adaptability is poor in areas with complex terrain. To solve the above problems, the industry has gradually developed spliced ​​cement utility poles, which reduce transportation costs and construction difficulty by decomposing the pole body into multiple units for transportation and on-site assembly. However, the existing splicing technology still has obvious defects:

[0003] Insufficient assembly stability: The sections of the pole body and the pole body and the foundation are only connected by simple bolts, and the connection strength is weak. Under the action of long-term loads (such as wind force and cable tension), it is easy to loosen and deflect, and even cause safety hazards.

[0004] The assembly operation is cumbersome: Traditional splicing structures lack precise positioning. During assembly, the segment positions need to be adjusted multiple times to align the connection holes, and the bolt tightening process requires repeated calibration, which increases construction time and labor costs.

[0005] Existing patent CN202510288529.6 discloses a modular, recyclable, assembled cement pole and its assembly process. The pole comprises a modular cement pole unit, an installation unit, and a cable support unit. The modular cement pole unit utilizes a multi-section assembly structure, with the installation unit semi-buried in the ground and the modular cement pole unit mounted on top. In this patent, the bottom of the cement pole is connected via a support base, anchor rods, a mounting base, and mounting bolts, resulting in poor installation stability. Furthermore, the direct use of bolts makes installation inconvenient. Summary of the Invention

[0040] like Figure 1As shown, a spliced ​​cement electric pole includes an upper pole 1, a lower pole 2 and a connecting pole 3 connected in sequence. The top end of the lower pole 2 is connected to the upper pole 1 through a connecting structure, and the bottom end of the lower pole 2 is connected to the connecting pole 3 through a connecting structure, thereby assembling a complete pole body. A connecting seat 4 is provided at the bottom end of the connecting pole 3, and the connecting seat 4 is provided on a pre-buried base 5. The base 5 and the connecting seat 4 are an integrated reinforced concrete structure, pre-buried underground. The connecting pole 3 can be pre-buried underground, or the top end can be exposed on the ground. A positioning mechanism is provided between the connecting pole 3 and the connecting seat 4, and the positioning mechanism includes a limiting structure and a locking structure. The limiting structure limits the connecting pole 3 and the connecting seat 4, and the locking structure performs a preliminary locking on the connecting pole 3 and the connecting seat 4, so as to facilitate the installation of the connecting pole 3.

[0041] like Figure 6 、 Figure 8 、 Figure 11 As shown, the limiting structure includes a slot 17 disposed at the center of the upper surface of the connecting base 4. The diameter of slot 17 is slightly larger than the outer diameter of the connecting rod 3, so that the bottom end of the connecting rod 3 is precisely inserted into slot 17. A plurality of positioning slots 25 are provided on both sides of slot 17. Positioning slots 25 are connected to slot 17 and are located on the upper surface of the connecting base 4.

[0042] like Figure 7 、 Figure 9 As shown, the locking structure includes a number of locking units corresponding to the positioning plate 14. The locking unit includes an insert block 23, which is slidably arranged in a sliding hole 24. The sliding hole 24 is vertically arranged in the connecting seat 4. A power structure is provided in the connecting seat 4 to drive the insert block 23 to slide up and down in the sliding hole 24. The positioning plate 14 is provided with a socket 15 for inserting the insert block 23 into the positioning plate 14, and the insert block 23 slides into the socket 15 along the sliding hole 24. A locking assembly for locking the insert block 23 is provided on the positioning plate 14, and the preliminary locking of the connecting seat 4 and the connecting rod 3 is achieved through the locking assembly.

[0043] The locking assembly includes a locking block 28, which is slidably arranged in a mounting groove 27, and the mounting groove 27 is arranged in the positioning plate 14. A locking hole is provided at one end of the insert block 23 close to the locking block 28.

An inclined surface is provided at the bottom of the end of the locking block 28 close to the insert block 23 to facilitate the insertion of the locking block 28 into the locking hole. A pull rod 29 is rotatably provided at the end of the locking block 28 away from the insert block 23 to facilitate pulling the locking block 28 to slide in the mounting groove 27. The pull rod 29 is rotatably and slidably connected to the positioning plate 14, and one end of the pull rod 29 is located outside the positioning plate 14.

[0044] like Figure 10 As shown, a limiting cylinder 31 is fixedly provided on the positioning plate 14, and the limiting cylinder 31 is located outside the pull rod 29.

A handle 32 is fixedly provided at the end of the pull rod 29, and the edge of the handle 32 is located in the through groove and slides along the through groove. The through groove has a limiting effect on the sliding of the pull rod 29. The handle 32 drives the locking block 28 to slide in the mounting groove 27 through the pull rod 29. The handle 32 slides to the end of the limiting cylinder 31 and rotates to slide out of the through groove. Under the action of the second spring 30, the locking block 28 is positioned to prevent the locking block 28 from rebounding under the action of the second spring 30, thereby facilitating the disassembly of the connecting rod 3.

[0045] like Figure 12 As shown, the power structure includes a connecting plate 20, which is located below the connecting seat 4. A lifting platform 18 is provided in the slot 17. The lifting platform 18 and the connecting plate 20 are fixedly connected by a plurality of guide rods 19. The guide rods 19 are slidably connected to the connecting seat 4. A first spring 21 is provided between the connecting plate 20 and the connecting seat 4 to facilitate the rebound of the connecting plate 20 and the removal of the plug 23 from the socket 15, thereby facilitating the removal of the connecting rod 3. The connecting seat 4 and the plug 23 are connected by a transmission plate 22, the middle portion of which is hinged to a fixed block 26. The fixed block 26 is fixedly mounted on the base 5. The fixing pins provided on the connecting plate 20 and the plug 23 are respectively located in the elongated holes provided at both ends of the transmission plate 22. The fixing pins are adapted to the elongated holes and slide along the elongated holes. The transmission plate 22 realizes transmission between the connecting plate 20 and the plug 23 through the elongated holes and the fixing pins.

[0046] A fixing plate 16 is fixed to the bottom end of the connecting rod 3, and a fixing hole is provided on the fixing plate 16. The fixing plate 16 is located above the connecting seat 4. The fixing plate 16 fixes the connecting rod 3 to the connecting seat 4 through bolts and fixing holes, thereby improving the stability of the connection between the connecting rod 3 and the connecting seat 4.

[0047] like Figure 2 As shown, the connection structure includes a flange 9, which is fixedly mounted at the bottom end of the upper rod 1, the ends of the lower rod 2, and the top end of the connecting rod 3. The flange 9 is provided with connection holes 10, through which bolts pass to securely connect the upper rod 1 to the lower rod 2, and the lower rod 2 to the connecting rod 3. Several reinforcing ribs 13 are evenly distributed on the outer wall of the flange 9 to enhance its strength.

[0048] like Figure 3 、 Figure 4 、 Figure 5As shown, the bottom inner wall of the upper rod 1 is provided with an annular groove 8. A boss 11 is fixedly mounted on the top inner wall of the upper rod 1, matching the groove 8. The boss 11 is inserted into the groove 8, ensuring the overlap between the upper rod 1 and the lower rod 2, and enhancing the stability and strength of the connection between the upper rod 1 and the lower rod 2. The sidewalls of the groove 8 are provided with several arcuate retaining grooves 6, one end of which is connected to a chute 7. The chute 7 is arranged axially along the upper rod 1 and extends to the bottom surface of the flange 9. A retaining pin 12 is fixedly mounted on the top outer wall of the boss 11, matching the chute 7 and the retaining groove 6. The retaining pin 12 slides along the chute 7 into the end of the retaining groove 6 away from the chute 7, achieving a preliminary connection between the upper rod 1 and the lower rod 2. The retaining grooves 6 and chute 7 ensure the positioning of the upper rod 1 and the lower rod 2, facilitating a secure locking between the upper rod 1 and the lower rod 2.

[0049] The above-mentioned method for assembling the spliced ​​cement utility pole comprises the following steps:

[0050] S1. Insert the boss 11 of the lower rod 2 into the groove 8 of the upper rod 1, and slide the limit pin 12 along the slide groove 7 to the end. Then rotate the upper rod 1 or the lower rod 2, and the limit pin 12 slides along the limit groove 6 to the end. At this time, the connecting hole 10 on the flange plate 9 at the bottom end of the upper rod 1 is exactly aligned with the connecting hole 10 on the flange plate 9 at the top end of the lower rod 2. The bolt passes through the connecting hole 10 and fixes the upper rod 1 and the lower rod 2 through the double nut.

[0051] S2. Insert the bottom end of the connecting rod 3 into the pre-buried slot 17 of the connecting base 4, and insert the positioning plate 14 into the positioning groove 25. Under the action of gravity, the connecting rod 3 pushes the lifting platform 18 downward. The lifting platform 18 drives the connecting plate 20 downward via the guide rod 19. The connecting plate 20 drives the insert block 23 upward along the slide hole 24 via the transmission plate 22. The insert block 23 is inserted into the insertion hole 15 of the positioning plate 14. The locking block 28, under the action of the second spring 30, is inserted into the locking hole of the insert block 23, completing the initial locking and positioning of the connecting rod 3 and the connecting base 4.

[0052] S3. Bolts are passed through the fixing holes on the fixing plate 16 and nuts are tightened to fix the connecting rod 3 and the connecting seat 4, thus completing the installation of the connecting rod 3.

[0053] S4. Lift the assembled upper rod 1 and lower rod 2, place the bottom end of the lower rod 2 on the top end of the connecting rod 3, align the connecting holes 10 on the flange 9, and fix the connecting rod 3 and the lower rod 2 with bolts and double nuts to complete the assembly.

[0054] In order to further improve the strength of the connection between the connecting rod 3 and the lower rod 2, the upper rod 1 and the lower rod 2 can also be connected.

[0055] Therefore, the use of the spliced ​​cement utility pole and the assembling method thereof described in the present invention can solve the problems of unstable assembly and inconvenient assembly operation of existing utility poles.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
