DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0033] Embodiment 1:

[0034] like Figures 1 to 3 As shown, this embodiment proposes a high-strength concrete pole, including: a skeleton and a concrete layer, the concrete layer is cast outside the skeleton; the skeleton includes: a central column 1, a support plate 2, a first end transverse plate 3, an intermediate transverse plate 4, a second end transverse plate 5, a reinforcing bar 6, a limit bar 7, a rotation limiting mechanism 8 and a limit-release block 9, the central column 1 is a cylindrical structure, at least three support plates 2 are distributed outside the central column 1, each support plate 2 is located in the radial direction of the central column 1, the central column 1 and the support plate 2 are welded with the first end transverse plate 3 at one end, the central column 1 and the support plate 2 pass through the second end transverse plate 5 and all the intermediate transverse plates 4, the second end cross plate 5 and the middle cross plate 4 can slide relative to the center column 1 and the support plate 2, the first end cross plate 3 is provided with a plug hole for the reinforcing strip 6 and the limiting block 9 to be inserted, the inner wall of the plug hole is recessed to form a rotating cavity for the limiting block 9 to rotate, the reinforcing strip 6 is fixed to the limiting block 9, the reinforcing strip 6 is a cylindrical structure, a limiting strip 7 is extended outside the reinforcing strip 6, the limiting strip 7 is recessed to form a plurality of limiting grooves, the second end cross plate 5 and each middle cross plate 4 are correspondingly provided with a limiting groove, and a rotation limiting mechanism 8 is formed at the connection between the reinforcing strip 6 and the second end cross plate 5, and the rotation limiting mechanism 8 is used to limit the rotation of the reinforcing strip 6.

[0035] In order to design a simple-structured rotation-limiting mechanism 8 and facilitate simultaneous adjustment of the rotation-limiting mechanism 8 and the reinforcing strip 6, the rotation-limiting mechanism 8 includes: an extension rod 81, an elastic member 82, and a rotation-limiting ring 83. The reinforcing strip 6 extends an extension rod 81 in a direction away from the first end cross plate 3. The extension rod 81 is connected to the rotation-limiting ring 83 through the elastic member 82. The rotation-limiting ring 83 can move in a direction parallel to the reinforcing strip 6 relative to the extension rod 81, and the rotation-limiting ring 83 cannot rotate relative to the extension rod 81. The second end cross plate 5 is provided with a rotation-limiting hole, and the rotation-limiting hole is used for inserting the rotation-limiting ring 83. Under the elastic force of the elastic member 82, the rotation-limiting ring 83 can be kept inserted into the rotation-limiting hole. The finger can keep the rotation-limiting ring 83 from being separated from the rotation-limiting hole, and the hand can rotate the reinforcing strip 6 at the same time, avoiding the need to keep the rotation-limiting ring 83 from being separated from the rotation-limiting hole with one hand and rotating the reinforcing strip 6 with the other hand, thereby simplifying the operation and improving the operation efficiency.

[0036] In order to install the elastic member 82 , the end of the extension rod 81 away from the reinforcing strip 6 extends to form an end plate 84 . The end plate 84 is connected to the elastic member 82 , and the rotation limiting ring 83 is located between the end plate 84 and the second end cross plate 5 .

[0037] In order to facilitate the installation of the elastic member 82 , the first spring can be installed by passing the limiting ring 83 and the first spring through the reinforcing strip 6 and the limiting strip 7 . The elastic member 82 is the first spring, and the first spring is located between the end plate 84 and the limiting ring 83 .

[0038] In order to prevent the limiting ring 83 from rotating relative to the extension rod 81, the extension rod 81 is located on the side of the second end cross plate 5 away from the middle cross plate 4. The extension rod 81 is a rectangular structure and does not extend into the second end cross plate 5. Therefore, the second end cross plate 5 cannot limit the rotation of the reinforcement strip 6 by interacting with the extension rod 81.

[0039] The rotation limiting ring 83 is a hollow rectangular parallelepiped structure, and the shape of the rotation limiting hole matches the shape of the rotation limiting ring 83 .

[0040] For the convenience of manufacturing, the limiting block 9 and the limiting strip 7 are both rectangular structures, and the extension rod 81, the limiting block and the limiting strip 7 are parallel to each other (that is, the sides of the extension rod 81, the limiting block and the limiting strip 7 are parallel to each other), so that they can be pulled out of the mold at one time during demoulding.

[0041] The first end cross plate 3 includes: a first plate body 31 and a second plate body 32, the first plate body 31 and the second plate body 32 are connected by screws, the first plate body 31 and the second plate body 32 are buckled to form a rotating cavity, a plug hole is provided on the first plate body 31, the first plate body 31 is welded to the central column 1 and the support plate 2, and a limiting mechanism 10 is clamped between the first plate body 31 and the second plate body 32, and the limiting mechanism 10 is used to limit the reinforcing strip 6 without the limiting strip 7 from being separated from the first end cross plate 3.

[0042] One reinforcement strip 6 is provided with a limit strip 7 , a rotation limiting mechanism 8 and a release limiting block 9 , while other reinforcement strips 6 are not provided with a limit strip 7 , a rotation limiting mechanism 8 and a release limiting block 9 . A limit release mechanism 10 is installed between the first plate body 31 and the second plate body 32 .

[0043] The limiting mechanism 10 includes: a moving seat 101, a limiting rod 102 and a second spring 103. The moving seat 101 is installed between the first plate body 31 and the second plate body 32. The moving seat 101 can move in a direction perpendicular to the reinforcing rod. The moving seat 101 acts on the limiting block 9. The moving seat 101 is fixed to one end of the limiting rod 102. The other end of the limiting rod 102 is inserted into the limiting groove formed by the depression of the reinforcing strip 6. The surface of the second plate body 32 close to the first plate body 31 is depressed to form an accommodating groove. The middle part of the limiting rod 102 is placed in the accommodating groove. The moving seat 101 moves under the guidance of the first plate body 31 and the second plate body 32. The contact surfaces between the moving seat 101 and the limiting block 9 are both arc surfaces, which avoids the moving seat 101 and the limiting block 9 from being easily damaged, protects the moving seat 101 and the limiting block 9, and extends their service life.

[0045] This embodiment provides a method for producing a high-strength concrete pole, comprising the following steps:

[0046] S1, prepare materials: S11, prepare the center column 1 and the support plate 2, the center column 1 and the support plate 2 are integrally formed during production; S12, prepare the first end horizontal plate 3, the middle horizontal plate 4 and the second end horizontal plate 5; S13, prepare the reinforcing strip 6, the limit strip 7, the rotation limiting mechanism 8 and the limit release block 9, the reinforcing strip 6, the limit strip 7 and the limit release block 9 are integrally formed during production, and the rotation limiting mechanism 8 is installed on the reinforcing strip 6;

[0047] S2, welding the first end horizontal plate 3 to the center column 1 and one end of the support plate 2;

[0048] S3, pass the central column 1 and the support plate 2 through the middle horizontal plate 4 and the second end horizontal plate 5, and ensure that the rotation limit hole of the second end horizontal plate 5 faces upward;

[0049] S4, pass the reinforcing strip 6, the limiting strip 7 and the limiting block 9 through the middle horizontal plate 4 and the second end horizontal plate 5, and insert the limiting block 9 into the first end horizontal plate 3;

[0050] S5, adjusting the positions of the second end transverse plate 5 and the middle transverse plate 4 so that the second end transverse plate 5 and each middle transverse plate 4 are aligned with a limiting groove;

[0051] S6, rotating the reinforcing bar 6, so that the second end transverse plate 5 and each middle transverse plate 4 are screwed into a limiting groove;

[0052] S7, adjusting the rotation limiting mechanism 8 to limit the rotation of the reinforcing strip 6; and

[0053] S8. Place the entire frame into a mold and use concrete to pour to form an electric pole.

[0054] Step S13 includes the following steps:

[0055] S131, prepare the reinforcing strip 6, the limiting strip 7, the extension rod 81, the end plate 84 and the limiting block 9, the reinforcing strip 6, the limiting strip 7, the extension rod 81, the end plate 84 and the limiting block 9 are integrally formed during manufacturing; and

[0056] S132, pass the reinforcing strip 6, the limiting strip 7, the extension rod 81 and the limiting block 9 through the first spring and the limiting rotation ring 83, and the first spring is located between the end plate 84 and the limiting rotation ring 83.

[0057] When preparing the first end cross plate 3 in step S12, the following steps need to be performed: S121, make the first plate body 31 and the second plate body 32; S122, prepare the movable seat 101, the limit rod 102 and the second spring 103, and the movable seat 101 and the limit rod 102 are integrally formed during the production; S123, pass the limit rod 102 through the second spring 103; S124, place the limit rod 102 into the receiving groove, and ensure that the second spring 103 is located between the movable seat 101 and the receiving groove wall; S125, buckle the first plate body 31 and the second plate body 32, and use screws to connect the first plate body 31 and the second plate body 32 to form the first end cross plate 3.

[0058] The design idea of ​​the present application is as follows: First, in order to prevent the troublesome operation caused by welding multiple various types of cross plates on the surface, a reinforcing strip 6 with a limiting strip 7, a rotation limiting mechanism 8 and a detachment limiting block 9 is designed, so that only one first end cross plate 3 needs to be welded, which simplifies the operation steps. By rotating the reinforcing strip 6, the middle cross plate 4 and the second end cross plate 5 are inserted into the limiting groove formed by the limiting strip 7, thereby stabilizing the distance between each cross plate and avoiding the random movement of each cross plate during the pouring process. Although the limiting force of the limiting groove wall on the middle cross plate 4 and the second end cross plate 5 is not very large, after the subsequent concrete is poured outside, the position of the middle cross plate 4 and the second end cross plate 5 can be made more stable. By rotating the reinforcing strip 6 and the extension rod 81, multiple middle cross plates 4 and the second end cross plate 5 can be positioned, which greatly simplifies the operation. The steps of operation are improved, and the operation efficiency is improved; furthermore, after the entire skeleton is installed, the skeleton needs to be moved to the molding mold. If the reinforcing strip 6 without the limit strip 7, the rotation limiting mechanism 8 and the limiting block 9 is only inserted into the first end cross plate 3, the middle end cross plate and the second end cross plate 5, it is very likely that the reinforcing strip 6 will be detached during the transfer process. In order to avoid this phenomenon, a limiting mechanism 10 is designed in one end cross plate. By implementing one limiting mechanism 10, more than two reinforcing strips 6 can be restricted from detaching. At the same time, only the limiting mechanism 10 needs to be installed during installation. Because when the middle cross plate 4 and the second end cross plate 5 are limited, the limiting block 9 can push the moving seat 101 to move, so that the limiting mechanism 10 limits the reinforcing strip 6, further simplifying the operation, and also stabilizing the position of the reinforcing strip 6, thereby improving the operation efficiency.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
