Description

Technical Field

[0001] The utility model relates to the technical field of cement poles, in particular to a high-strength cement pole. Background Art

[0002] As the name implies, electric poles are poles for electric wires. Electric poles play the role of supporting overhead wires. Common electric poles include wooden poles, cement poles, power towers, etc. Electric poles appear in various rural areas, fields, roads, and streets, and are one of the important infrastructures in early China. Concrete poles are poles made of concrete and steel bars or steel wires, which are prestressed and non-prestressed; iron poles are poles cast in pig iron. Various early electric poles started with wooden poles, even including high-voltage poles with not too high voltage levels. Later, due to the development of steel and reinforced concrete, and technical requirements, these two materials replaced most wooden poles.

[0003] When installing existing cement poles, the strength and stability of the poles are mainly determined by the strength of the cement poles themselves and the pre-embedded depth in the ground. If the pre-embedded depth is shallow, the poles are prone to shaking or even collapse. For example, the utility model patent with application number 202220972308.2 discloses a new type of cement pole, including a mounting chassis and a pole body. The pole body is fixed at the center of the top surface of the mounting chassis, and a circular array of reinforcing ribs is provided on the top surface of the mounting chassis. A climbing ring is fixed in an array in the vertical direction on the surface of the reinforcing ribs. The reinforcing ribs pass through the surface of the climbing ring. A mounting ring is provided near the top of the pole body. The mounting ring has the same structure as the climbing ring. A limit device is provided inside the mounting chassis. The limit device includes a power motor and a folding ring plate. The inner wall of the folding ring plate is against the outer wall of the climbing ring.

[0004] Although the above patent enhances the strength and stability of the pole body by providing reinforcing ribs and climbing rings, in the technical solution of the patent, the pole body is fixed only by inserting the mounting bolts at the edge of the mounting chassis into the ground. In places with loose soil, the bonding between the mounting bolts and the ground is poor, and the bolts may become loose after long-term use, thereby affecting the stability of the pole.

[0005] Therefore, it is necessary to develop a high-strength cement pole to address the above defects. Utility Model Content

[0009] Furthermore, the support plate has a right triangle cross section, there are four support plates and they are fixedly connected to the top surface of the fixing ring at the bottom.

[0010] Furthermore, a fixing plate is fixedly connected to the bottom of the support plate, and a plurality of threaded holes are opened on both sides of the fixing plate. The fixing plate is fixed to the top surface of the base by bolts passing through the threaded holes.

[0028] In a specific embodiment, Figures 1 to 4 As shown, it includes a pole body 1 and a base 2. A socket 3 is opened in the middle of the base 2, and the pole body 1 is vertically inserted into the socket 3; a steel skeleton 4 is cast inside the pole body 1, and the steel skeleton 4 includes longitudinal tie bars 401 and fixing rings 402; the longitudinal tie bars 401 are vertically arranged and longitudinally distributed along the circumference of the pole body 1, and a plurality of fixing rings 402 are horizontally spaced and fixedly connected to each longitudinal tie bar 401; a support plate 5 is fixedly connected to the bottom of the longitudinal tie bar 401, and the support plate 5 is vertically arranged and fixedly connected to the top surface of the base 2.

[0029] By pouring a steel skeleton 4 inside the pole body 1, the longitudinal tie bars 401 are reinforced by a fixing ring 402, thereby enhancing the strength of the pole body 1; at the same time, a base 2 is provided, a socket 3 is provided on the base 2, the bottom of the pole body 1 is inserted into the socket 3, and then the pole body 1 is fixed to the base 2 by a supporting plate 5, thereby improving the bonding strength between the pole body 1 and the ground, enhancing the overall stability of the cement pole, and being suitable for installation and use under different geological environment conditions.

[0030] In a specific embodiment, the cross section of the support plate 5 is a right triangle, there are four support plates 5 and the bottom surfaces are fixedly connected to the top surface of the fixing ring 402 at the bottom by welding.

[0031] By setting the support plate 5 to a right-angled triangle shape, the bottom surface of the support plate 5 is fixedly connected to the top surface of the fixing ring 402, and when the support plate 5 is fixed on the base 2, the overall weight of the pole body 1 can be dispersed to the longitudinal tensioning rod 401 through the fixing ring 402, thereby reducing the weight borne by the bottom of the pole body 1, enhancing the strength of the pole body 1, and extending the service life of the pole body 1.

[0032] Specifically, a fixing plate 6 is fixedly connected to the bottom of the support plate 5 , and a plurality of threaded holes 7 are provided on both sides of the fixing plate 6 . The fixing plate 6 is fixed to the top surface of the base 2 by bolts passing through the threaded holes 7 .

[0033] The support plates 5 are fixed to the top surface of the base 2 by bolts through the fixing plates 6 arranged at the bottom of the support plates 5 , so as to prevent the pole body 1 from rotating on the base 2 .

[0034] In a specific embodiment, a plurality of first connection rings 8 are fixedly connected to the outer wall of the middle fixing ring 402, and the first connection rings 8 extend out of the pole body 1; a second connection ring 9 is correspondingly fixedly connected to the top surface of the base 2, and the first connection rings 8 and the second connection rings 9 are connected by a steel cable 10.

[0035] By setting the first connecting ring 8 and the second connecting ring 9, and then connecting the first connecting ring 8 and the second connecting ring 9 through the steel cable 10, the connection strength between the base 2 and the pole body 1 is improved. When encountering severe weather such as strong winds, the steel cable 10 can pull and fix the pole body 1, so that the pole body 1 always remains in a vertical state. At the same time, fixing the first connecting ring 8 on the outer wall of the fixing ring 402 can disperse the tension force on the pole body 1 to the longitudinal tie rod 401, reducing the force on the cement part of the pole body 1.

[0036] In a specific embodiment, the outer wall of the base 2 is fixedly connected with fins 11 , and a plurality of fins 11 are vertically arranged and evenly distributed on the circumference of the base 2 .

[0037] By providing the fins 11 on the base 2, when the base 2 is buried in the ground, the contact area between the base 2 and the ground is increased, thereby improving the stability of the installation of the base 2.

[0038] Specifically, the fins 11 and the base 2 are integrally cast using cement.

[0039] In a specific embodiment, a protective sleeve 12 is provided in the middle of the outer wall of the pole body 1 , the protective sleeve 12 is fixedly connected to the first connecting ring 8 , and the inner wall of the protective sleeve 12 is tightly fitted to the outer wall of the pole body 1 .

[0040] By such arrangement, the tension on the first connecting ring 8 can be dispersed to the outer wall of the pole body 1 , thereby preventing cracks from occurring in the cement portion of the outer wall of the pole body 1 and increasing the service life of the pole body 1 .

[0041] In a specific implementation, the longitudinal reinforcement 401 is made of threaded steel bars.

[0042] Due to the simulated graining and other processing processes on the surface of the steel, the surface hardness of the steel can be improved, and the tensile and bending strength of the steel can also be improved. The rebar has the characteristics of high strength, high hardness, durability and stability. Casting it inside the pole body 1 can improve the strength of the pole body 1.

[0043] Working principle of the utility model: bury the base 2 in the ground so that the top surface of the base 2 is not higher than the bottom surface, then insert the bottom of the pole body 1 into the socket 3 on the base 2, and make the first connecting ring 8 and the second connecting ring 9 on the pole body 1 correspond one by one, so that the first connecting ring 8 is located directly above the second connecting ring 9. Then, bolts are respectively passed through the threaded holes 7 on the fixing plate 6 to fix the support plate 5 on the top surface of the base 2, and then the first connecting ring 8 and the second connecting ring 9 are respectively connected with the steel cable 10, and the steel cable 10 is tightened to keep it in a taut state, and the installation of the high-strength cement pole of the utility model is completed.
