Description

Technical Field

[0001] This utility model relates to the field of cement pole technology, and in particular to the pole segment connection structure of cement poles. Background Technology

[0002] Prefabricated concrete poles typically refer to pole structures assembled on-site from multiple precast concrete segments. This design divides the entire pole into several sections, primarily to alleviate the difficulties of transporting long poles, making them easier to move to complex terrain areas, and assemble them into a complete pole on-site.

[0003] Currently, flange connections are commonly used between pole segments. This involves pre-embedding steel flanges at the ends of each pole segment. During construction, the lower pole segment is fixed first, and then a crane is used to lift the upper segment to a high altitude for connection. After the bolt holes of the upper and lower flanges are aligned, high-strength bolts are inserted and tightened to form a whole pole segment.

[0004] During the connection of the pole segments, the technicians found that because the upper pole segment was suspended in the air, the pole segment was heavy, and due to the swaying of the crane and the tilt of the lifting point, the flange hole positions could not be quickly aligned during the connection, which affected the construction efficiency to some extent. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0006] Therefore, one objective of this utility model is to propose a segment connection structure for cement poles, characterized by the inclusion of an axis positioning component and an angle positioning component. During hoisting construction, this structure can guide the flange hole positions of the upper and lower pole segments to automatically align, achieving rapid and accurate docking, effectively reducing the difficulty of manual adjustment, and significantly improving the efficiency of flange connection.

[0007] To achieve the above objectives, the first aspect of this utility model proposes a segment connection structure for a cement pole, comprising: an upper pole segment, a lower pole segment, and a connecting mechanism, wherein the lower pole segment is disposed below the upper pole segment, and the connecting mechanism comprises a reinforcing component, an axis positioning component, and an angle positioning component, wherein the reinforcing component is disposed between the upper pole segment and the lower pole segment, the axis positioning component is disposed at the bottom inner side of the reinforcing component, and the angle positioning component is disposed outside the axis positioning component.

[0008] In addition, the pole segment connection structure of the cement pole proposed above according to this utility model may also have the following additional technical features: Specifically, the reinforcement assembly includes a first flange and a second flange, wherein the first flange is installed on the inner side of the bottom end of the upper rod section, and a plurality of first positioning rods are connected to the inner wall of the first flange; the second flange is installed on the inner side of the top end of the lower rod section, and a plurality of second positioning rods are connected to the inner wall of the second flange.

[0009] Specifically, the axis positioning assembly includes an elastic telescopic rod, multiple support frames, and multiple limiting members. The fixed part of the elastic telescopic rod is fixedly installed on the inner bottom end of the second flange. The multiple support frames are respectively disposed on the outer side of the elastic telescopic rod. Multiple connecting rods are rotatably connected between the top of the support frame and the moving part of the elastic telescopic rod, and between the bottom of the support frame and the fixed part of the elastic telescopic rod. The multiple limiting members are respectively installed between the corresponding support frame and the fixed part of the elastic telescopic rod.

[0010] Specifically, the limiting component includes a slide rail, a sliding frame, and multiple connecting tubes. The slide rail is installed on the side of the support frame near the connecting rod. The sliding frame is slidably installed on the inner side of the slide rail. Multiple insert rods are fixedly connected to one side of the sliding frame. The multiple connecting tubes are respectively fixedly installed on the outer side of the fixed part of the elastic telescopic rod. The insert rods are slidably connected to the connecting tubes.

[0011] Specifically, the angle positioning assembly includes multiple limiting rods, two clamping frames, two rollers, and multiple springs. The multiple limiting rods are respectively fixedly installed on the side of the support frame away from the connecting rod. The two clamping frames are respectively slidably installed on both sides of the support frame and are slidably connected to the corresponding limiting rods. The two rollers are respectively rotatably connected to the side of the two clamping frames away from the support frame. The multiple springs are respectively sleeved on the outside of the corresponding limiting rods and support and push the two clamping frames away from each other.

[0012] Compared with existing technologies, this invention has the following advantages: Through the coordinated operation of the axis positioning component and the angle positioning component, this invention can automatically perform centering and circumferential angle correction during the lowering of the hoisting pole section, eliminating the need for repeated manual adjustments and quickly achieving precise alignment of the upper and lower flange hole positions. This structure significantly reduces the difficulty and risk of high-altitude operations and greatly improves docking efficiency and connection reliability.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The pole segment connection structure of the cement pole according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0020] like Figures 1-3 As shown in the figure, a segment connection structure for a cement pole according to an embodiment of the present invention includes: an upper pole segment 1, a lower pole segment 2, and a connecting mechanism 3.

[0021] The lower rod segment 2 is located below the upper rod segment 1. The connecting mechanism 3 includes a reinforcing component 31, an axis positioning component 32, and an angle positioning component 33. The reinforcing component 31 is located between the upper rod segment 1 and the lower rod segment 2. The axis positioning component 32 is located at the bottom inner side of the reinforcing component 31. The angle positioning component 33 is located outside the axis positioning component 32.

[0022] Specifically, technicians will use the pole segment connection structure of this cement pole for quick connection when performing pole segment connection.

[0023] First, the technicians pre-embedded the lower pole section 2 into the ground and fixedly connected the lower pole section 2 to the ground.

[0024] Then, the technicians used a crane to lift the upper pole section 1 and transport it above the lower pole section 2, and then initially aligned the upper pole section 1 and the lower pole section 2.

[0025] Next, the technicians operated the crane to gradually lower the upper pole section 1. The reinforcement component 31 inside the upper pole section 1 triggered the axis positioning component 32 located at the bottom inner side of the reinforcement component 31 of the lower pole section 2. The axis positioning component 32 simultaneously supported the upper pole section 1 and the lower pole section 2 from the inside, so that the axis of the upper pole section 1 and the axis of the lower pole section 2 coincided, preventing the upper pole section 1 from shifting or tilting during docking.

[0026] At the same time, the angle positioning component 33 on the outside of the axis positioning component 32 also starts to operate. As the axis positioning component 32 simultaneously supports the upper rod segment 1 and the lower rod segment 2 from the inside, the angle positioning component 33 contacts and squeezes the inside of the upper and lower rod segments, aligning the reinforcing component 31 between the upper and lower rod segments, making it convenient for workers to directly use bolts to drill holes later.

[0027] Finally, the technicians used a lift to reach the connecting mechanism 3 and used bolts to lock the reinforcing components 31 of the upper and lower rod sections, thus completing the connection of the upper and lower rod sections.

[0028] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the reinforcement component 31 includes a first flange 311 and a second flange 313.

[0029] The first flange 311 is installed on the inner side of the bottom end of the upper rod section 1, and multiple first positioning rods 312 are connected to the inner wall of the first flange 311.

[0030] The second flange 313 is installed on the inner side of the top of the lower rod section 2, and multiple second positioning rods 314 are connected to the inner wall of the second flange 313.

[0031] Specifically, the first flange 311 and the upper rod section 1 are pre-cast integrally, and the second flange 313 and the lower rod section 2 are pre-cast integrally.

[0032] Specifically, the first limiting rod 331 and the second limiting rod 331 are welded and fixed to the first flange 311 and the second flange 313 respectively, and the first limiting rod 331 and the second limiting rod 331 have the same specifications. When the first limiting rod 331 and the second limiting rod 331 are aligned, the positioning holes on the first flange 311 and the second flange 313 are aligned.

[0033] The axis positioning assembly 32 includes an elastic telescopic rod 321, multiple support frames 322, and multiple limiting members 324.

[0034] The fixing part of the elastic telescopic rod 321 is fixedly installed on the bottom inner side of the second flange 313.

[0035] Multiple support frames 322 are respectively arranged on the outside of the elastic telescopic rod 321. Multiple connecting rods 323 are rotatably connected between the top of the support frame 322 and the moving part of the elastic telescopic rod 321, and between the bottom of the support frame 322 and the fixed part of the elastic telescopic rod 321.

[0036] Multiple limiting components 324 are respectively installed between the fixed parts of the corresponding support frame 322 and the elastic telescopic rod 321.

[0037] Specifically, a compression plate is fixedly connected to the top of the moving part of the elastic telescopic rod 321.

[0038] It should be noted that the diameter of the fixed part and the diameter of the moving part of the elastic telescopic rod 321 connected to the connecting rod 323 are the same.

[0039] The limiting component 324 includes a slide rail 3241, a sliding frame 3242, and multiple connecting pipes 3244.

[0040] It should be noted that when the elastic telescopic rod 321 is not compressed or contracted, the support frame 322, under the connection of the connecting rod 323 and the restriction of the limiting member 324, is parallel and attached to the outside of the elastic telescopic rod 321. Specifically, the slide rail 3241 is installed on the side of the support frame 322 near the connecting rod 323, and the sliding frame 3242 is slidably installed on the inside of the slide rail 3241. Multiple insert rods 3243 are fixedly connected to one side of the sliding frame 3242, and multiple connecting pipes 3244 are respectively fixedly installed on the outside of the fixed part of the elastic telescopic rod 321. The insert rods 3243 and the connecting pipes 3244 are slidably connected.

[0041] The angle positioning assembly 33 includes multiple limit rods 331, two clamping frames 332, two rollers 333, and multiple springs 334.

[0042] Among them, multiple limiting rods 331 are fixedly installed on the side of the support frame 322 away from the connecting rod 323, two clamping frames 332 are slidably installed on both sides of the support frame 322, and the two clamping frames 332 are slidably connected to the corresponding limiting rods 331, two rollers 333 are rotatably connected to the side of the two clamping frames 332 away from the support frame 322, and multiple springs 334 are respectively sleeved on the outside of the corresponding limiting rods 331, and the multiple springs 334 respectively support and push the two clamping frames 332 away from each other.

[0043] It should be noted that there are two requirements for the initial alignment of the upper and lower rod segments. First, the first flange 311 must be fitted onto the outside of all the support frames 322 to facilitate the support frames 322 to be supported. Second, all the first positioning rods 312 must be inserted between the two clamping frames 322 in the corresponding angle positioning components 33 to facilitate the clamping frames 322 to align the first positioning rods 312 and the second positioning rods 314.

[0044] Specifically, after the upper rod section 1 is hoisted above the lower rod section 2 to meet the initial alignment requirements, the upper rod section 1 is gradually lowered so that the first flange 311 gradually contacts and presses down on the compression plate at the top of the moving part of the elastic telescopic rod 321, causing the elastic telescopic rod 321 to contract. As the elastic telescopic rod 321 contracts, the connecting rod 323 on the outside of the moving part and the fixed part of the elastic telescopic rod 321 rotates. The connecting rod 323 pushes the support frame 322 outward. When the support frame 322 is pushed outward, it drives the sliding frame 3242 away from the elastic telescopic rod 321, and the sliding frame 3242 slides in the slide rail 3241, restricting the support frame 322 to always remain parallel to the elastic telescopic rod 321.

[0045] As the support frame 322 expands outward, the roller 333 contacts the inner walls of the first flange 311 and the second flange 313 respectively. Since the inner walls of the first flange 311 and the second flange 313 are arc-shaped, the two clamping frames 332 are driven to gradually approach each other from both sides of the first positioning rod 312 and the second positioning rod 314.

[0046] When the first flange 311 and the second flange 313 come into contact, the first positioning rod 312 and the second positioning rod 314 are tightly clamped and aligned by the clamping brackets 332 on both sides. The axes of the upper rod section 1 and the lower rod section 2 are synchronously expanded and aligned by multiple support brackets 322, completing the precise automatic alignment of the upper rod section 1 and the lower rod section 2. Technicians can use bolts to lock and fix the aligned first flange 311 and the second flange 313.

[0047] In summary, the segment connection structure of this utility model for cement poles achieves rapid and precise docking of pole segments through the synergistic action of the reinforcing component 31, the axis positioning component 32, and the angle positioning component 33. After the lower pole segment 2 is pre-embedded and fixed, the upper pole segment 1 is hoisted and initially aligned before being lowered. During the lowering process, the axis positioning component 32 is triggered, and the elastic telescopic rod 321 retracts, causing the support frame 322 to expand outward, thus internally tightening the upper and lower pole segments to ensure axis alignment. At the same time, the clamping frame 332 in the angle positioning component 33 gradually retracts under the push of the support frame 322, clamping and aligning the positioning rods on the upper and lower flanges. Finally, the connection is completed by fixing the flanges with bolts. This structure significantly improves docking accuracy and construction efficiency.
