Description

Technical Field

[0001] The present application relates to the technical field of power transmission pole end protection, and in particular to an anti-cracking protection device for a power transmission pole end. Background Art

[0002] Power transmission refers to the transmission of electricity generated by power plants to places where electricity is needed through transmission lines. It is the core link in the power industry, involving the transmission, distribution and reception of electric energy to ensure a stable supply of electricity. At present, high-voltage circuits are usually transmitted using iron tower transmission racks, while after the voltage is stepped down at local distribution stations, electricity transmission for local residents, industries, etc. is usually transmitted using smaller cement transmission poles.

[0003] At present, the distance between adjacent cement transmission poles is small when they are transported in the line, so a large number of transmission poles are needed when laying transmission poles in the local power supply area. Transmission pole manufacturing companies pile up transmission poles after continuous production and when transporting them to the power supply area. Figure 1 As shown in the figure, during transportation, the poles are also piled up on the transport vehicle. The main body of the cement transmission pole is cast in concrete. There are collisions between the transmission poles during hoisting and transportation and during unloading after transportation. Figure 2 As shown, there is a high probability of impact and breakage at the end of the transmission pole, which increases the company's production, transportation and replacement costs. In addition, during the later assembly process, the bottom end of the transmission pole will inevitably contact the ground, which will still cause the problem of impact and breakage at the bottom end. Summary of the invention

[0004] In response to the above-mentioned problems, the present application aims to provide a transmission pole end anti-cracking protection device, which provides a ring-shaped protection for the transmission pole that is easily broken under the impact of external forces, especially the end, thereby reducing the risk of easy cracking at the transmission pole end and reducing production and transportation costs.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a collision-proof crack protection device at the end of a transmission pole, characterized in that: the protection device is ring-circled at the end of the transmission pole, and an anti-separation structure is arranged on the inner side where the protection device abuts against the transmission pole, and the protection device is also provided with a strength enhancement structure connected to the transmission pole.

[0006] Preferably, the protection device is a metal protection sleeve that is looped around the end of the transmission pole.

[0007] Preferably, the anti-detachment structure is an embedding body provided on the inner wall of the metal protective sleeve and can be embedded in the outer wall of the transmission pole end.

[0008] Preferably, the transmission pole end has a stepped surface encircled by a metal protective sleeve;

[0009] The strength enhancement structure is an extension portion extending from the metal protective sleeve in the inner direction away from the end of the transmission pole and attached to the outer wall of the transmission pole.

[0010] The beneficial effects of the present application are as follows: the protective device is sleeved on the end of the transmission pole, and the transmission pole that is easily broken under the impact of external forces, especially the end, is protected by the sleeve, thereby reducing the risk of the transmission pole end being easily broken, and reducing the cost of production and transportation. The anti-detachment structure can effectively increase the integrity of the protective device sleeve on the conical structure of the transmission pole, thereby avoiding the disadvantage that the protective device is easy to fall during transportation and fails to play a protective role. And the strength enhancement structure can further increase the protection area of ​​the protective device and improve the protection effect on the transmission pole.

[0021] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0022] See attached Figures 1 to 8 A transmission pole end anti-cracking protection device is shown. The protection device is ring-shaped at the end of the transmission pole 1. The transmission pole that is easily broken under the impact of external force, especially the end, is protected by the ring-shaped protection, thereby reducing the risk of easy cracking of the transmission pole end and reducing the costs of production and transportation.

[0023] At present, cement transmission poles are usually cone-shaped, that is, large at the bottom and small at the top. During transportation, the transmission poles are laid flat, and the protective device is easy to detach from the cone-shaped transmission poles. Figure 4 As shown, in order to improve the integrity of the protection device and the transmission pole, an anti-separation structure is provided on the inner side where the protection device abuts against the transmission pole 1, which can effectively increase the integrity of the protection device ring on the conical structure of the transmission pole 1, thereby avoiding the disadvantage that the protection device is easy to fall during transportation and fails to play a protective role.

[0024] In order to further improve the protective effect of the protective device on the end of the transmission pole, the protective device is also provided with a strength enhancement structure connected to the transmission pole 1. Since the protective device only realizes partial protection of the end of the transmission pole, after the protective position of the protective device on the transmission pole 1 is hit by external force, it will affect the unprotected part of the transmission pole. Therefore, the strength enhancement structure can further increase the protection area of ​​the protective device and improve the protection effect of the transmission pole.

[0025] Specifically, Figure 3 As shown, the protective device is a metal protective sleeve 2 that is sleeved on the ends of the transmission pole 1. It is sleeved on both ends of the transmission pole 1 during the casting process of the transmission pole. After the transmission pole is solidified, the metal protective sleeve 2 sleeved on the two ends can effectively improve the protection during stacking and transportation, and ensure the integrity of the transmission pole 1.

[0026] To avoid the problem that the metal protective cover 2 is separated from the transmission pole 1 of the conical structure, as Figure 5-6 As shown, the anti-detachment structure is an embedding body 21 which is arranged on the inner wall of the metal protective sleeve 2 and can be embedded in the outer wall of the end of the transmission pole 1. Figure 5-6 As shown, the embedding body 21 can be a protrusion or a groove. When casting the transmission pole, the cement casting material will be embedded in the groove or the protrusion will be embedded in the transmission pole 1, thereby achieving the embedding tightness between the metal protective cover 2 and the outer wall of the transmission pole 1, solving the problem that the metal protective cover 2 is easy to fall off the transmission pole 1.

[0027] like Figure 7As shown, the protective height of the metal protective sleeve 2 on the end of the transmission pole 1 is equal to the width of the metal protective sleeve 2. When the metal protective sleeve 2 is hit by an external force, the end of the transmission pole 1 with the same width as the metal protective sleeve 2 will be broken from the transmission pole 1 body. Figure 8 Therefore, to solve this problem, Figure 8 As shown, the end of the transmission pole 1 has a step surface 1a surrounding the metal protective sleeve 2, that is, the inner diameter of the metal protective sleeve 2 is smaller than the outer diameter of the transmission pole, and then when the transmission pole 1 is formed, the step surface 1a can be formed on the outer wall of the transmission pole 1 through the inner wall surface of the metal protective sleeve 2.

[0028] like Figure 8 As shown in FIG. 1 , the strength enhancement structure is an extension portion 22 extending from the metal protective sleeve 2 toward the inner side away from the end of the transmission pole 1 and attached to the outer wall of the transmission pole 1. After the metal protective sleeve 2 is sleeved on the step surface 1a of the transmission pole 1, the extension portion 22 continues to extend from the step surface toward the inner side of the transmission pole 1 away from the end, as shown in FIG. Figure 8 As shown, Figure 7 When the impact is shown, the extension portion 22 and the main body of the transmission pole 1 are encircled to resist the problem of partial breakage of the transmission pole 1 at the step surface 1a, thereby further improving the protective effect of the metal protective sleeve 2 on the end of the transmission pole 1.

[0029] The principle of the present application is: during the molding and casting process of the transmission pole 1, the metal protective sleeve 2 is sleeved on the end of the transmission pole 1, and a step surface 1a that is in close contact with the transmission pole 1 is formed at the end of the transmission pole 1, and the embedded body 21 is embedded and fastened with the main body of the transmission pole 1, and the extension part 22 continues to protect the transmission pole 1 inward along the step surface 1a, so that the end can be effectively protected during the stacking and transportation process after the transmission pole is produced and formed, avoiding the problem that the end of the transmission pole 1 is easily broken by external force.

[0030] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
