[0002] A cement pole is a commonly used support device in the process of erecting power cables. After the steel reinforcement cage is tied, it is formed by pouring concrete. Due to its low raw material cost, high structural strength, and good corrosion resistance under normal circumstances, it was widely used in the initial stage of building the power system in our country. The traditional cement pole is formed by integral casting, and currently, multi-section assembled cement poles are mostly used in the market.

[0003] However, in some extreme regions, the corrosion and weathering rate of cement is fast, resulting in a short service life. While the cost of electric poles made of pure metal is high, and their strength is not as good as that of cement poles, and at the same time, the recycling difficulty is large. At the same time, the top of the cement pole is usually fixed with multiple groups of cables by installing a support arm to extend outward. However, this makes the cable maintenance and repair process difficult, and it needs to be moved to the side bracket, which requires a higher strength of the side bracket and has a higher risk.

[0021] By providing a modular recyclable prefabricated cement pole and its assembly process in the embodiments of the present application, the problems of short service life, difficult recycling and high cable maintenance difficulty of the existing prefabricated cement poles are solved.

[0022] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0023] The embodiments of the present invention disclose a modular recyclable prefabricated cement pole and its assembly process. Embodiment

[0024] As shown in the attached Figures 1-9 figure, it includes a modular cement pole unit 1, an installation unit 2 and a cable support unit 3. The modular cement pole unit 1 adopts a multi-section assembled structure. The installation unit 2 is installed in a semi-buried manner on the ground, and the modular cement pole unit 1 is installed on its top; The modular cement pole unit 1 includes a metal outer cylinder 11, a ladder 12, a cement pipe 13, a connecting piece 14, a connecting flange 15, an assembly chamber 16 and fixing bolts 17. The connecting flanges 15 are integrally formed at both ends of the metal outer cylinder 11 and are used for assembling two adjacent groups of metal outer cylinders 11. The cement pipe 13 is detachably arranged inside the metal outer cylinder 11 and is used to provide supporting force. The connecting piece 14 is arranged between two adjacent groups of metal outer cylinders 11 and is used to connect two adjacent groups of cement pipes 13. A ladder 12 is fixedly welded to the outer wall of the metal outer cylinder 11, and fixing bolts 17 are fixedly installed inside the connecting flange 15, and the fixing bolts 17 penetrate through the connecting piece 14.

[0025] The connecting piece 14 includes an embedded flange plate 141, a plug rod 142 and a positioning pipe 143 which are integrally formed on the upper and lower sides of the embedded flange plate 141 respectively. An assembly chamber 16 is formed inside the connecting flange 15, and the embedded flange plate 141 is installed in the assembly chamber 16. The cement pipe 13 is hollow, and a jack 132 is formed in the side wall at the bottom end of the cement pipe 13. The positioning pipe 143 is movably inserted into the bottom cement pipe 13, and the plug rod 142 is movably inserted into the jack 132 of the top cement pipe 13. The lowermost connecting piece 14 is installed in the installation unit 2.

[0026] The installation unit 2 includes a support base 21, an anchor rod 22, an installation base 23, an assembly positioning groove 24 and installation studs 25. The anchor rod 22 is installed at the bottom of the support base 21. The installation base 23 is installed on the top of the support base 21 by bolts. The assembly positioning groove 24 runs through the middle parts of the support base 21 and the installation base 23, and a group of positioning pipes 143 penetrate through the assembly positioning groove 24. The installation studs 25 are threadedly connected to the side wall of the installation base 23 and penetrate into the lowermost cement pipe 13.

[0027] Working principle: When the device is assembled, first, the ground is tamped and leveled. Then, the support base 21 is anchored to the ground through the anchor rod 22, and then the installation base 23 is fixed to the support base 21 by bolts to complete the assembly of the installation unit 2. Then, the cement pipe 13 is inserted into the metal outer cylinder 11. Then, the embedded flange plate 141 is installed at the bottom of the metal outer cylinder 11, and the plug rod 142 is inserted into the jack 132. Then, one modular cement pole unit 1 is installed in the installation base 23, so that the positioning pipe 143 penetrates through the assembly positioning groove 24. Then, the installation stud 25 is installed into the cement pipe 13. Then, multiple modular cement pole units 1 are stacked vertically upwards in sequence, and the upper positioning pipe 143 is inserted into the lower cement pipe 13. Then, fixing bolts 17 are installed between two connecting flanges 15 for splicing. In this way, two adjacent groups of cement pipes 13 are nested through the positioning pipe 143, preventing the fixing bolts 17 from loosening and breaking due to shaking at the connection, and playing an anti-bending role. Before installing the topmost modular cement pole unit 1, first install a plurality of cable support units 3 on its outer surface, and then hoist them to the top for assembly, thus completing the overall installation. Embodiment

[0028] Refer to the attached Figures 1-9 As shown, on the basis of the first embodiment, more specifically, the cable support unit 3 includes a support arm 31, a cable mounting bracket 32, and a traction member 36. The support arm 31 is installed on the side wall of the top of the modular cement pole unit 1. The cable mounting bracket 32 is arranged on the support arm 31. The traction member 36 is arranged inside the support arm 31 and is used to traction the cable mounting bracket 32 to move along the support arm 31 towards or away from the modular cement pole unit 1, and the traction member 36 is used to fix the cable mounting bracket 32.

[0029] One end of the support arm 31 is fixedly welded with a connecting seat 33. The connecting seat 33 is fixedly installed on the outermost metal outer cylinder 11 at the top through bolts. An insulating terminal 35 is installed on the cable mounting bracket 32. A sliding groove 34 is formed on the outer surface of the support arm 31. The cable mounting bracket 32 slides along the sliding groove 34 under the traction of the traction member 36.

[0030] The traction member 36 includes a slip ring 361, a self-locking mechanism 362, an annular traction steel cable 363, a fixed pulley 366, and a winding roller 367. The slip ring 361 is integrally formed in the middle of the cable mounting bracket 32 and is slidably arranged on the outer surface of the support arm 31. The self-locking mechanism 362 is fixedly arranged inside the slip ring 361 and is movably clamped with the inner part of one end of the support arm 31. The winding roller 367 is rotatably arranged inside the other end of the support arm 31. The fixed pulley 366 is installed inside the support arm 31. One end of the annular traction steel cable 363 is wound around the outer surface of the winding roller 367, and the other end bypasses the outer surface of the fixed pulley 366. The annular traction steel cable 363 is connected to the self-locking mechanism 362. A threaded groove is formed on the surface of the winding roller 367. The annular traction steel cable 363 is wound in the threaded groove and extends towards the fixed pulley 366 at both ends. Thus, when the winding roller 367 rotates, one side of the annular traction steel cable 363 is wound up, and the other side of the annular traction steel cable 363 is released, so as to effectively drive the annular traction steel cable 363 to move.

[0031] The self-locking mechanism 362 includes a sliding block 3621, a wedge block 3622, a movable slot 3623, a retaining ring 3624, a triangular plug 3625, a plug slot 3626, and a spring 3627. The sliding block 3621 is slidably disposed in the support arm 31, and both sides of the annular traction cable 363 pass through the upper and lower ends of the sliding block 3621 respectively; the wedge block 3622 is movably inserted into both sides inside the sliding block 3621, and it is movably inserted into the support arm 31; the movable slot 3623 is opened inside the sliding block 3621; the retaining ring 3624 is slidably disposed in the movable slot 3623, and it is fixedly connected to the annular traction cable 363; the plug slot 3626 is opened in the wedge block 3622; the triangular plug 3625 is movably inserted into the plug slot 3626, and its top is fixedly connected to the retaining ring 3624; the spring 3627 is disposed between the two sets of wedge blocks 3622.

[0032] A fixing portion 37 is fixedly welded to the inner wall of the support arm 31. The wedge block 3622 is movably inserted into the fixing portion 37. A worm gear 364 is fixedly disposed on the side surface of the winding roller 367. A worm 365 is rotatably disposed inside the support arm 31. The worm 365 meshes with the worm gear 364.

[0033] Working principle: When the device is in use, the cable mounting bracket 32 is at the end of the support arm 31, and the cables are fixed to the insulating terminals 35, thereby realizing the isolated erection of multiple groups of cables; During maintenance, the operator climbs to the top of the modular cement pole unit 1 through the ladder 12. At this time, by inserting the hexagon wrench into the top inside of the worm 365 and then rotating it clockwise, the worm 365 drives the worm gear 364 to rotate, so that the winding roller 367 rotates clockwise. At this time, the winding roller 367 winds up the upper side of the annular traction cable 363 and releases the lower side of the annular traction cable 363, so that the annular traction cable 363 moves on the outer surface of the fixed pulley 366. At this time, the annular traction cable 363 drives the retaining ring 3624 to move. The retaining ring 3624 moves inside the movable slot 3623 towards one end close to the winding roller 367. First, it drives the triangular plug 3625 to move, so that the triangular plug 3625 pushes the two sets of wedge blocks 3622 towards the middle, compressing the spring 3627. At this time, the wedge blocks 3622 move out of the fixing portion 37. At this time, the retaining ring 3624 abuts against the inner end of the movable slot 3623. At this time, the retaining ring 3624 pushes the entire sliding block 3621 to move along with the annular traction cable 363, so that the entire cable mounting bracket 32 moves along the sliding groove 34 towards one end close to the metal outer cylinder 11. And because the worm gear 364 and the worm 365 have self-locking properties, the insulating terminals 35 continuously drive the cables to move to the side of the metal outer cylinder 11, thus facilitating maintenance; After the overhaul is completed, reverse-rotate the worm 365 to drive the worm wheel 364 to rotate in the reverse direction, causing the annular traction cable 363 to move in the reverse direction. At this time, the retaining ring 3624 first slides to the other end inside the movable groove 3623. At this time, under the action of the spring 3627, the two wedge-shaped blocks 3622 move outward from inside the sliding block 3621. Then, the retaining ring 3624 pushes the sliding block 3621 to move along with the annular traction cable 363 towards the outer end of the support arm 31. When the sliding block 3621 moves to the fixing part 37, the inclined surface of the wedge-shaped block 3622 abuts against the outer side wall of the fixing part 37, causing the wedge-shaped block 3622 to be squeezed into the sliding block 3621, compressing the spring 3627. When the sliding block 3621 is in place, the wedge-shaped block 3622 moves outward under the action of the spring 3627 and is inserted into the fixing part 37, thus achieving automatic locking. At this time, stop rotating the worm 365, so that the cable mounting bracket 32 moves to the outer end of the support arm 31 and achieves self-locking fixation. At the same time, the annular traction cable 363 is further self-locked through the worm wheel 364 and the worm 365, effectively preventing the cable mounting bracket 32 from moving during use.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
