Description

Technical Field

[0001] The present disclosure belongs to the field of assembled electric poles, and particularly relates to an assembled concrete electric pole. Background Art

[0002] In power engineering and telecommunications infrastructure construction, concrete poles are widely used to support electrical wires, communication lines, and other equipment. Traditionally, concrete pole installation methods involve digging a deep pit at the construction site, pouring a large concrete base at the bottom, and then erecting the pole on the base. While this method ensures the stability of the pole, the on-site pouring of the base is time-consuming and labor-intensive, potentially leading to low efficiency and increased construction costs. To improve construction efficiency, modern technologies have introduced solutions with prefabricated bases and poles.

[0003] For example, Chinese patent application number CN202322520086.8 discloses an assembled tower foundation structure, including a tower mechanism, a seat mechanism disposed on the outside of the tower mechanism, a reinforcement mechanism disposed on the outside of the tower mechanism, and a first connecting mechanism and a second connecting mechanism disposed on the outside of the tower mechanism. This assembled tower foundation structure first plugs into a first slot to connect the seat mechanism and the tower mechanism, then plugs into a third slot and a second slot to connect the reinforcement mechanism to the seat mechanism and the tower mechanism, then screws a threaded rod into the lower end of the tower body to fix the position between the seat mechanism and the tower mechanism, and finally screws a connecting sleeve into a fixing slot to fix the position between the reinforcement mechanism and the seat mechanism and the tower mechanism, thereby solving the problems existing in cast-in-place concrete foundations and integral prefabricated foundations.

[0004] However, in the above patent, the threaded rod needs to be threadedly connected to the lower end of the tower body during assembly, and the screw rod is arranged on a connecting plate connected to the seat mechanism. Since the tower and the seat mechanism are both heavy, it is not convenient to rotate them to achieve threaded connection, and it is more difficult to rotate the two to achieve threaded connection. Therefore, there is a problem in the prior art that it is inconvenient to assemble the pole body and the base. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention aims to provide an assembled concrete pole, which solves the problem in the prior art that it is inconvenient to assemble the pole body and the base.

[0006] The purpose of this disclosure can be achieved through the following technical solutions:

[0007] An assembled concrete pole comprises a pole body and a base;

[0008] The rod body is in the shape of a cylindrical shell placed vertically with an open lower end. Two first circular through holes are opened at different heights on the peripheral wall of the rod body near the lower end. The central axes of the first circular through holes pass perpendicularly through the central axis of the rod body. The first circular through holes penetrate the peripheral walls on both sides of the lower end of the rod body, and the vertical planes where the central axes of the two first circular through holes are located are perpendicular to each other.

[0009] The base is arranged directly below the rod body, and a pair of second circular through holes corresponding to the first circular through holes are opened on the peripheral wall of the base, and the diameter of the second circular through holes is equal to that of the first circular through holes. The upper end surface of the base is opened with a circular groove for accommodating the rod body, and the diameter of the outer peripheral wall of the circular groove is equal to the diameter of the outer peripheral wall of the rod body, and the diameter of the inner peripheral wall of the circular groove is equal to the diameter of the inner wall of the rod body. When the lower end of the rod body is inserted into the circular groove, any second circular through hole can be placed coaxially with the corresponding first circular through hole;

[0010] A sliding rod is slidably connected to each of the second circular through holes. The sliding rod has the same diameter as the second circular through hole, and the sliding rod passes through the first circular through hole corresponding to the second circular through hole. The sliding rod is detachably connected to the base through a locking portion.

[0011] The principles and effects of the above technical solution are as follows:

[0012] During assembly, first insert the lower end of the rod into the circular groove, and place the first circular through hole on the rod coaxially with the corresponding second circular through hole on the base. Then insert the sliding rod into the base from the side of the second circular through hole, so that the sliding rod passes through the first circular through hole. Finally, lock the sliding rod and the base with the locking part to install.

[0013] The installation process of the base and the pole body is simple and convenient, which solves the problem in the prior art of inconvenient assembly of the pole body and the base. At the same time, the matching arrangement of the two sliding rods and the circular groove can ensure the stability of the installation connection between the pole body and the base.

[0014] Four first slots are provided on the outer peripheral wall of the lower end of the rod body, and are placed vertically downward. The four first slots are evenly distributed in a ring shape around the central axis of the rod body. The first slots pass through the lower end of the rod body, and the width of the first slots away from the outer peripheral wall of the rod body is greater than the width of the first slots near the outer peripheral wall of the rod body.

[0015] Four first clamping strips are fixed on the outer peripheral wall of the annular groove, which are adapted to and correspond to the first clamping grooves one by one. The first clamping strips are used to be inserted into the corresponding first clamping grooves and slidably connected thereto;

[0016] Four second clamping strips are fixed to the inner peripheral wall of the rod body and are evenly distributed in a ring around the central axis of the rod body. The second clamping strips are all coaxially placed with the rod body, and the lower ends of the second clamping strips are flush with the lower end of the rod body. The width of the second clamping strip near the central axis of the rod body is greater than the width of the second clamping strip away from the central axis of the rod body.

[0017] Four second clamping grooves are provided on the inner peripheral wall of the annular groove, which are adapted to and correspond to the second clamping strips one by one. The second clamping strips are used to be inserted into the corresponding second clamping grooves and slidably connected thereto.

[0018] Any second card strip is located between two adjacent first card slots. Any two second card strips arranged opposite to each other constitute a group. The two groups of second card strips correspond one-to-one to the two first round through holes. Any first round through hole passes through the two second card strips in the corresponding group.

[0019] The locking portion includes a pair of bolts respectively fixed to the two ends of the slide rod, the bolts are coaxially placed with the slide rod, the diameter of the bolts is smaller than the diameter of the slide rod, and when the slide rod is inserted into the second circular through hole, the bolts at both ends of the slide rod extend out of the second circular through hole, and nuts are threadedly sleeved on the bolts, and the circumscribed diameter of the nuts is larger than the diameter of the second circular through hole;

[0020] A pad is fixed at a position on the peripheral wall of the base corresponding to the second circular through hole, and a third circular through hole is opened on the pad and is placed coaxially with the second circular through hole. The diameter of the third circular through hole is greater than or equal to the diameter of the slide rod. One end of the pad is in contact with the peripheral wall of the base, and the other end of the pad is in a vertical plane perpendicular to the central axis of the third circular through hole. The circumscribed circle diameter of the nut is greater than the diameter of the third circular through hole.

[0021] There are two nuts sleeved on the bolts.

[0022] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0023] Fixed connection: refers to the process of connecting two separate profiles or parts into a complex part or component using fasteners such as screws, bolts and rivets.

[0024] Threaded connection: refers to the connection and fixation between objects achieved through the mutual engagement of threads.

[0025] Beneficial effects of the present disclosure:

[0026] 1. When assembling, you only need to insert the lower end of the rod into the circular groove first, and place the first circular hole on the rod coaxially with the corresponding second circular hole on the base. Then, insert the slide rod into the base from the side of the second circular hole, so that the slide rod passes through the first circular hole. Finally, lock the slide rod and the base with the locking part to install.

[0027] The installation process of the base and the pole body is simple and convenient, which solves the problem of inconvenience in assembling the pole body and the base in the prior art. At the same time, the coordinated arrangement of the two sliding rods and the circular groove can ensure the stability of the connection between the pole body and the base during installation.

[0028] 2. The coordinated arrangement of the first slot, the first clip strip, the second slot, and the second clip strip improves the stability of the connection between the rod body and the base, and facilitates the positioning of the first circular through hole and the corresponding second circular through hole, thereby avoiding deviation and misalignment between the first circular through hole and the corresponding second circular through hole after the rod body is inserted into the circular groove, thereby facilitating the subsequent insertion of the sliding rod;

[0029] 3. By arranging the first circular through hole through the second clamping strip, when the slide rod is inserted through the first circular through hole, the thickness of the rod wall at the contact point between the rod body and the slide rod is increased, thereby improving the strength of the contact point between the rod body and the slide rod and reducing the risk of the rod wall at the contact point between the rod body and the slide rod during subsequent use;

[0030] 4. The arrangement of bolts and nuts at both ends of the slide bar facilitates the detachable connection between the slide bar and the base, and the arrangement of two nuts on each bolt improves the stability of the fit between the bolts and nuts. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0038] Combined here Figures 1 to 5An embodiment of an assembled concrete pole will now be described. Specifically, the assembled concrete pole is constructed as a split structure, comprising a pole body, a base 200, a slide bar 300, and a locking portion. During assembly, the lower end of the pole body 100 is first inserted into the annular groove 202, and the first circular through hole 101 on the pole body 100 is coaxially positioned with the corresponding second circular through hole 201 on the base 200. The slide bar 300 is then inserted into the base 200 from the side of the second circular through hole 201, passing through the first circular through hole 101. Finally, the slide bar 300 is locked and installed with the base 200 using the locking portion.

[0039] The installation process of the base 200 and the rod body 100 is simple and convenient, and the coordinated arrangement of the two sliding rods 300 and the annular groove 202 can ensure the stability of the installation connection between the rod body 100 and the base 200.

[0040] Please refer to Figures 1 to 5 , an assembled concrete pole, comprising a pole body 100 and a base 200;

[0041] The rod body 100 is in the shape of a cylindrical shell placed vertically with an open lower end. Two first circular through holes 101 at different heights are opened on the peripheral wall of the rod body 100 near the lower end. The central axes of the first circular through holes 101 pass perpendicularly through the central axis of the rod body 100. The first circular through holes 101 pass through the peripheral walls on both sides of the lower end of the rod body 100, and the vertical planes where the central axes of the two first circular through holes 101 are located are perpendicular to each other.

[0042] The base 200 is arranged directly below the rod body 100. A pair of second circular through holes 201 corresponding to the first circular through holes 101 are opened on the peripheral wall of the base 200. The second circular through holes 201 are equal in diameter to the first circular through holes 101. A circular groove 202 is opened on the upper end surface of the base 200 for placing the rod body 100. The outer peripheral wall diameter of the circular groove 202 is equal to the outer peripheral wall diameter of the rod body 100, and the inner peripheral wall diameter of the circular groove 202 is equal to the inner wall diameter of the rod body 100. When the lower end of the rod body 100 is inserted into the circular groove 202, any second circular through hole 201 can be placed coaxially with the corresponding first circular through hole 101.

[0043] A sliding rod 300 is slidably connected to each of the second circular through holes 201. The sliding rod 300 has the same diameter as the second circular through hole 201 and passes through the first circular through hole 101 corresponding to the second circular through hole 201. The sliding rod 300 is detachably connected to the base 200 via a locking portion.

[0044] The pole body 100 is usually made of concrete or other composite materials. A steel frame is usually wrapped inside the pole body 100 to ensure sufficient strength and durability to support the functional requirements of the pole.

[0045] The base 200 is made of concrete or other composite materials. In this embodiment, the base 200 is circular. In actual use, the base 200 can also be selectively made into other shapes such as rectangle and triangle.

[0046] The slide bar 300 is usually made of metal materials, such as stainless steel, carbon steel or alloy steel, to ensure its strength and durability, suitable for long-term use and bearing corresponding loads. The surface of the slide bar 300 can usually be galvanized or sprayed with an anti-rust coating to further improve its corrosion resistance.

[0047] The pole body 100 and base 200 of the concrete pole are prefabricated separately and can be assembled together when in use. During assembly, the lower end of the pole body 100 is first inserted into the annular groove 202, and the first circular through hole 101 on the pole body 100 is placed coaxially with the corresponding second circular through hole 201 on the base 200. Then, the sliding rod 300 is inserted into the base 200 from the side of the second circular through hole 201, so that the sliding rod 300 passes through the first circular through hole 101. Finally, the sliding rod 300 and the base 200 are locked and installed by the locking part.

[0048] The installation process of the base 200 and the pole body 100 is simple and convenient, which solves the problem in the prior art that it is inconvenient to assemble the pole body 100 and the base 200. At the same time, the matching arrangement of the two sliding rods 300 and the annular groove 202 can ensure the stability of the installation connection between the pole body 100 and the base 200.

[0049] In order to improve the stability of the connection between the rod body 100 and the base 200 and to facilitate the coaxial placement of the second round through hole 201 and the corresponding first round through hole 101 during installation, four first clamping grooves 102 arranged vertically downward are opened on the outer peripheral wall of the lower end of the rod body 100. The four first clamping grooves 102 are evenly distributed in a ring shape around the central axis of the rod body 100. The first clamping grooves 102 pass through the lower end of the rod body 100, and the width of the first clamping grooves 102 away from the outer peripheral wall of the rod body 100 is greater than the width of the first clamping grooves 102 close to the outer peripheral wall of the rod body 100.

[0050] Four first clamping strips 203 are fixed on the outer peripheral wall of the annular groove 202, which are adapted to and correspond to the first clamping slots 102 one by one. The first clamping strips 203 are used to be inserted into the corresponding first clamping slots 102 and slidably connected thereto;

[0051] By cooperating with the first card slot 102 and the first card strip 203, the stability of the connection between the rod body 100 and the base 200 can be improved, and the first circular through hole 101 and the corresponding second circular through hole 201 can be positioned conveniently, thereby avoiding deviation and misalignment between the first circular through hole 101 and the corresponding second circular through hole 201 after the rod body 100 is inserted into the annular groove 202, thereby facilitating the subsequent insertion of the sliding rod 300.

[0052] Four second clips 103 are fixed to the inner peripheral wall of the rod body 100 and are evenly distributed in a ring around the central axis thereof. The second clips 103 are all coaxially arranged with the rod body 100. The lower ends of the second clips 103 are flush with the lower end of the rod body 100, and the width of the second clips 103 near the central axis of the rod body 100 is greater than the width of the second clips 103 away from the central axis of the rod body 100.

[0053] Four second slots 204 are provided on the inner peripheral wall of the annular groove 202, which are adapted to and correspond to the second clip strips 103. The second clip strips 103 are used to be inserted into the corresponding second slots 204 and slidably connected thereto; this can further improve the stability of the rod body 100 and the base 200 after installation and connection.

[0054] Any second clip 103 is located between two adjacent first slots 102, and any two second clips 103 arranged relative to each other form a group, and the two groups of second clips 103 correspond one-to-one to the two first circular through holes 101, and any first circular through hole 101 passes through the two second clips 103 in the corresponding group; by setting the second clip 103 and the first circular through hole 101 passing through the second clip 103, when the sliding rod 300 is inserted through the first circular through hole 101, the thickness of the rod wall at the contact part between the rod body 100 and the sliding rod 300 is increased, the strength of the contact part between the rod body 100 and the sliding rod 300 is improved, and the risk of the rod wall at the contact part between the rod body 100 and the sliding rod 300 being broken during subsequent use is reduced.

[0055] In order to facilitate the detachable connection between the sliding rod 300 and the base 200, the locking part includes a pair of bolts 301 respectively fixed at both ends of the sliding rod 300. The bolts 301 are placed coaxially with the sliding rod 300. The diameter of the bolts 301 is smaller than the diameter of the sliding rod 300. When the sliding rod 300 is inserted into the second circular through hole 201, the bolts 301 at both ends of the sliding rod 300 extend out of the second circular through hole 201. Nuts 302 with threaded connections are sleeved on the bolts 301. The circumscribed circle diameter of the nuts 302 is larger than the diameter of the second circular through hole 201. Before the sliding rod 300 is inserted into the second circular through hole 201, the nuts 302 are removed first. After the bolts 301 at both ends extend out of the second circular through hole 201, the nuts 302 are tightened on the bolts 301 until the nuts 302 are squeezed into contact with the base 201.

[0056] In order to improve the contact stability between the nut 302 and the base 200, a pad 400 is fixed at the position of the second circular through hole 201 on the peripheral wall of the base 200, and a third circular through hole is opened on the pad 400 and is placed coaxially with the second circular through hole 201. The diameter of the third circular through hole is greater than or equal to the diameter of the slide rod 300. One end of the pad 400 is in contact with the peripheral wall of the base 200, and the other end of the pad 400 is in the shape of a vertical plane perpendicular to the central axis of the third circular through hole. The circumscribed circle diameter of the nut 302 is greater than the diameter of the third circular through hole; when the nut 302 is tightened, it is in contact with the pad 400.

[0057] There are two nuts 302 sleeved on the bolt 301 to improve the stability of the connection between the nut 302 and the bolt 301.
