Description

Technical Field

[0001] This utility model relates to the field of cement pole technology, and in particular to a modular utility pole that is easy to transport. Background Technology

[0002] Cement utility poles are mainly made of cement and internal reinforcement. They are important auxiliary equipment in power line transmission. Most common cement utility poles are not easy to disassemble, which makes transportation inconvenient.

[0003] To facilitate transportation, modular cement utility poles are increasingly used. However, in existing technologies, such as the modular cement utility pole described in patent CN219974053U, a threaded hole is drilled in the main pole, and a threaded pipe is fixed to the auxiliary pole, connecting the auxiliary pole to the main pole via a threaded connection. This requires screwing the main pole or auxiliary pole for thread fixing, which is not only inconvenient in practice, but also prone to slippage due to misalignment between the main pole and auxiliary pole during operation, easily affecting the construction progress. Therefore, there is an urgent need for a modular utility pole that is easy to transport and solves the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a modular utility pole that is easy to transport, so as to solve the problems existing in the prior art and realize the construction and assembly of the modular utility pole.

[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides a modular utility pole that is easy to transport, comprising:

[0006] The main rod has a top ring fixed to the top of its inner cavity. The top ring is arranged coaxially with the main rod, and a connection range is defined between the outer periphery of the top ring and the inner ring of the main rod.

[0007] A secondary rod is positioned above the main rod. A connecting sleeve is fixed to the bottom end of the secondary rod. The outer circumference of the connecting sleeve is threaded, and the inner ring of the connecting sleeve abuts against the outer circumference of the top ring.

[0008] A retaining ring is located between the main rod and the auxiliary rod. The top and bottom surfaces of the retaining ring are respectively provided with a first groove and a second groove. The bottom end of the auxiliary rod is embedded in the first groove, and the top end of the main rod is embedded in the second groove. A casting hole is provided on one side of the retaining ring, and the two ends of the casting hole extend through the connection section and the outside.

[0010] Preferably, a second connecting ring is fixedly connected to the top of the main rod, the outer wall of the second connecting ring is welded to the reinforcing bars inside the main rod, and the top ring is coaxially fixed to the inner ring side of the second connecting ring.

[0011] Preferably, the top ring is a tapered structure with its tip facing the auxiliary rod, and a through hole is provided in the center of the top ring. The inner diameter of the connecting sleeve is greater than the smallest diameter end of the top ring and smaller than the largest diameter end of the top ring.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figures 1-3 This utility model provides a modular utility pole that is easy to transport, comprising:

[0025] Main rod 1, with a top ring 2 fixedly connected to the top of the inner cavity. The top ring 2 is arranged coaxially with the main rod 1, and a connection range is defined between the outer periphery of the top ring 2 and the inner ring of the main rod 1.

[0026] The auxiliary rod 3 is set above the main rod 1. The bottom end of the auxiliary rod 3 is fixed with a connecting sleeve 4. The outer circumference of the connecting sleeve 4 is threaded, and the inner ring of the connecting sleeve 4 abuts against the outer circumference of the top ring 2.

[0027] The retaining ring 5 is located between the main rod 1 and the auxiliary rod 3. The top and bottom surfaces of the retaining ring 5 are respectively provided with a first groove 51 and a second groove 52. The bottom end of the auxiliary rod 3 is embedded in the first groove 51, and the top end of the main rod 1 is embedded in the second groove 52. A casting hole is provided on one side of the retaining ring 5, and the two ends of the casting hole are connected to the section and the outside.

[0028] This technical solution defines a connection interval between the top rod and the inner ring side of the main rod 1, and abuts the connecting sleeve 4 at the bottom of the auxiliary rod 3 against the outer circumference of the top ring 2. The threaded portion of the connecting sleeve 4 is arranged within the connection interval, and the abutment between the connecting sleeve 4 and the top ring 2 isolates the inner side of the connection interval. Furthermore, by setting a retaining ring 5 between the main rod 1 and the auxiliary rod 3, the auxiliary rod 3 is fitted into the first groove 51 and the main rod 1 into the second groove 52, thus covering and isolating the outer side of the connection interval. Communication with the interior of the connection interval is only achieved through a pouring hole on one side of the retaining ring 5. The main rod 1 and the auxiliary rod 3 are connected and fixed by pouring concrete. Simultaneously, the threads on the outer wall of the connecting sleeve 4 increase the contact area with the poured concrete, improving the connection stability between the main rod 1 and the auxiliary rod 3. Compared to existing technologies that connect utility poles by screwing in threads, this patent effectively achieves the goal of facilitating the construction and assembly of modular utility poles.

[0029] Furthermore, a first connecting ring 6 is fixedly connected to the bottom of the inner part of the secondary rod 3. The outer wall of the first connecting ring 6 is welded to the reinforcing bars inside the secondary rod 3. The connecting sleeve 4 is coaxially fixed to the inner ring side of the first connecting ring 6.

[0030] Furthermore, a second connecting ring 7 is fixedly connected to the top of the main rod 1. The outer wall of the second connecting ring 7 is welded to the reinforcing bars inside the main rod 1, and the top ring 2 is coaxially fixed to the inner ring side of the second connecting ring 7.

[0031] Specifically, during the casting and preparation of the main pole 1 and the auxiliary pole 3, the first connecting ring 6 and the second connecting ring 7 are welded and fixed to the reinforcing bars inserted inside them to form the prefabricated structure of the main pole 1 and the auxiliary pole 3. The combined structure of the main pole 1 and the auxiliary pole 3 facilitates transportation, and the main pole 1 and the auxiliary pole 3 are assembled at the pole installation site. The ease of combination between the main pole 1 and the auxiliary pole 3 improves construction efficiency.

[0032] Furthermore, the top ring 2 is a tapered structure with its tip facing the auxiliary rod 3. A through hole is opened in the center of the top ring 2. The inner diameter of the connecting sleeve 4 is greater than the smallest diameter end of the top ring 2 and smaller than the largest diameter end of the top ring 2.

[0033] By designing the top ring 2 as a conical structure, under the fixed support of the first connecting ring 6 and the second connecting ring 7, the top ring 2 abuts against the connecting sleeve 4, and the connecting sleeve 4 is fixed on the inclined side wall of the top ring 2, thereby improving the connection stability between the main rod 1 and the auxiliary rod 3.

[0034] Furthermore, the outer periphery of the retaining ring 5 is provided with several vent holes, which are connected to the connecting section.

[0035] During the concrete pouring process, the vent holes effectively fill the connection area with concrete, ensuring the contact and fixation effect between the concrete and the outer wall of the connecting sleeve 4.

[0036] Furthermore, the length of the secondary rod 3 is not less than one-quarter of the length of the main rod 1, and the length of the secondary rod 3 does not exceed one-half of the length of the main rod 1.

[0037] Specifically, taking a common 15-meter utility pole as an example, by setting the length of the main pole 1 to 12 meters and the length of the auxiliary pole 3 to 3 meters, since the common utility pole structure is hollow at the bottom and solid at the top, the main pole 1 and auxiliary pole 3 are combined to form a composite utility pole. This facilitates transportation, and by making the main pole 1 hollow and the auxiliary pole 3 solid, the bending resistance of the overall utility pole after combination can be improved.

[0038] Furthermore, an annular base 8 is fixedly connected to the bottom end of the main rod 1, improving the stability of the fixed support for the main rod 1.

[0039] This utility model provides a connection process for a modular utility pole that is easy to transport:

[0040] Place the main rod 1 and the auxiliary rod 3 horizontally, and move the connecting sleeve 4 toward the top ring 2 until the connecting sleeve 4 extends into the main rod 1. Continue to move the auxiliary rod 3 along the direction of the main rod 1, and the main rod 1 also provides a movement tendency along the direction of the auxiliary rod 3, until the auxiliary rod 3 is embedded in the first groove 51 and the main rod 1 is embedded in the second groove 52. The connecting sleeve 4 and the top ring 2 are pressed together, so that the positions of the main rod 1 and the auxiliary rod 3 are coaxially distributed. Then, pour concrete into the pouring hole. During the pouring process, gently tap the retaining ring 5 to expel the concrete and the air in the connection area through the vent hole, so that the concrete fills the connection area. After concrete seeps out from the vent hole at the top and the pouring hole is also filled with concrete, wait for the concrete to dry completely, thus completing the combination connection of the main rod 1 and the auxiliary rod 3.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
