Description

Technical Field

[0001] This invention relates to the field of cement pole technology, specifically to a high-performance cement pole with a bottom end resistant to salt and alkali treatment and its manufacturing process. Background Technology

[0002] Cement poles can be used in power transmission lines, substations, and other applications. They can also be used to support communication lines and serve as streetlights, providing support for urban street lighting.

[0003] When installing existing cement poles, the bottom of the pole needs to be fixed. After fixing, the exposed part of the cement pole is supported again to further stabilize it. However, since the part supported on the cement pole has a certain height, a support mechanism needs to be installed each time it is supported. Moreover, because the installed support mechanism is quite high, it needs to be disassembled when the cement pole needs to be replaced, and the support mechanism also needs to be disassembled when a new cement pole is installed. This is a cumbersome operation. To address this, we propose a high-performance cement pole with a bottom anti-salt and alkali treatment and its manufacturing process. Summary of the Invention

[0004] This invention provides a high-performance cement pole with a bottom end resistant to salt and alkali treatment and its manufacturing process to solve the problems mentioned in the background art. When installing existing cement poles, the bottom of the pole needs to be fixed. After fixing, to further stabilize the pole, the exposed part is supported again. However, since the supported part of the pole has a certain height, a support mechanism needs to be installed each time it is supported.

[0009] As a preferred embodiment of the present invention, the fixing mechanism includes a vertical support ear, the vertical support ear being positioned corresponding to the oblique support ear, a bolt being movably installed inside the vertical support ear, and a nut being threaded onto the bolt.

[0010] As a preferred embodiment of the present invention, side plates are fixedly installed on both sides of the mounting plate, and insertion holes are opened on the top of the four side plates, and positioning steel nails are installed in the four insertion holes.

[0011] As a preferred embodiment of the present invention, the limiting mechanism includes a rotating groove formed on the annular side of the mounting column, an arc-shaped hole formed on the side of each of the four mounting plates, a rotating ring rotatably mounted in the four arc-shaped holes and the rotating groove, four top rods fixedly mounted on the top of the rotating rings, an arc-shaped column fixedly mounted on the top of each of the four top rods, the side of each of the four arc-shaped columns respectively contacting the side of each of the four L-shaped rods, and a limiting component mounted on each of the four rotating rings.

[0013] As a preferred embodiment of the present invention, a threaded hole is provided on one side of the inner wall of the rotating ring, a stud is installed in the threaded hole, and one end of the stud extends out of the threaded hole and is fixedly installed with an L-shaped handle.

[0014] A manufacturing process for a high-performance cement pole with a bottom end resistant to salt and alkali treatment, the process comprising the following steps: Step 1: Prepare high-quality cement, graded aggregates, suitable admixtures, and standard-compliant steel bars, and measure them accurately for later use; at the same time, clean and inspect the molds and apply release agent to prepare for subsequent production. Step 2: First, make the steel reinforcement into a skeleton and install it into the mold. Then, pour the well-mixed concrete into the mold in layers. After completion, apply anti-salt and alkali coating to the bottom of the cement pole and wrap it with anti-salt and alkali material. Then, steam curing and natural curing are carried out to make it reach the specified strength. Step 3: Conduct a visual inspection of the cement poles to ensure that the surface is free of defects; measure their dimensions to ensure that they meet the design requirements; test their compressive and flexural strength, and cement poles that pass the strength test are considered finished products.

[0015] Compared with the prior art, the present invention provides a high-performance cement pole with bottom end resistant to salt and alkali treatment and its manufacturing process, which has the following beneficial effects: During installation, the present invention first installs the mounting column, then installs the cement pole. After the cement pole is placed in, the moving mechanism moves, causing the four supporting mechanisms to rotate and align with the positions of the four fixed mechanisms. The four fixed mechanisms can fix the four supporting mechanisms respectively, thereby supporting the cement pole. During installation, the four supporting mechanisms are positioned low, which facilitates the placement of the cement pole. At the same time, the moving mechanism triggers the limiting mechanism, thereby limiting the bottom end of the cement pole.

[0016] In this invention, the four L-shaped rods move downwards, causing the four arc-shaped pillars to gradually separate from the four L-shaped rods. When the four arc-shaped pillars separate from the four L-shaped rods respectively, the four return springs are in a deformed state. Under the action of the four return springs, the four return sleeves move. The movement of the four return sleeves drives the four locking rods to move. The four locking rods enter the annular locking groove, thereby further limiting the bottom of the cement rod, thus facilitating the quick fixation of the cement rod. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention necessarily exceeds the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but still fall within the protection scope of this application.

[0020] Figures 1-9 This is the preferred embodiment of the present invention, which is described below in conjunction with the accompanying drawings. Figures 1-9 The present invention will be further described below.

[0021] This invention discloses a high-performance cement pole with a bottom end resistant to salt and alkali treatment, comprising a cement pole 3, a rectangular block 32 fixedly installed at the bottom of the cement pole 3, an annular limiting groove opened on the side of the cement pole 3, a rotating sleeve 1 rotatably installed in the annular limiting groove, four fixing mechanisms installed on the rotating sleeve 1, a mounting column 5 with a tapered bottom end set below the rotating sleeve 1, a circular groove opened at the top of the mounting column 5, the circular groove being adapted to the cement pole 3, four support mechanisms installed at the top of the mounting column 5, a moving mechanism installed at the bottom of the mounting column 5, a limiting mechanism installed on the side of the mounting column 5, the limiting mechanism and the moving mechanism being installed in cooperation, and the moving mechanism being installed in cooperation with the four support mechanisms.

[0022] With the above structure: during installation, the mounting column 5 is installed first, and then the cement rod 3 is installed. After the cement rod 3 is placed, the moving mechanism moves, thereby causing the four support mechanisms to rotate and correspond to the positions of the four fixed mechanisms. The four fixed mechanisms can fix the four support mechanisms respectively, thereby supporting the cement rod 3. During installation, the four support mechanisms are positioned low, which facilitates the placement of the cement rod 3. At the same time, the moving mechanism will trigger the limiting mechanism, thereby limiting the bottom end of the cement rod 3.

[0023] like Figure 5 , Figure 7 and Figure 8As shown, the moving mechanism includes movable slots 36 formed on the inner walls of the four sides of the circular groove. Each of the four movable slots 36 has a moving hole 31 on its top inner wall. Each of the four movable slots 36 has a movable block 33 slidably installed inside it. A circular seat 35 slidably installed inside the circular groove is fixedly installed on the side of the four movable blocks 33 that are close to each other. A rectangular slot 34 corresponding to the rectangular block 32 is formed on the top of the circular seat 35. A moving spring 37 is fixedly installed on the bottom of the circular seat 35. The bottom end of the moving spring 37 is fixedly installed on the bottom inner wall of the circular groove. An L-shaped rod 6 is fixedly installed on the top of each of the four movable blocks 33. The top ends of the four L-shaped rods 6 pass through the four moving holes 31 and are respectively connected to the four support mechanisms. The rectangular block 32 on the cement rod 3 is aligned with the rectangular groove 34 and moved. When the rectangular block 32 enters the rectangular groove 34, the bottom of the cement rod 3 contacts the top of the round seat 35. Under the weight of the cement rod 3, the round seat 35 moves downward. The movement of the round seat 35 drives the four movable blocks 33 to move downward and contact the bottom inner wall of the four movable grooves 36 respectively. The moving spring 37 is deformed, and the movement of the four movable blocks 33 drives the four L-shaped rods 6 to move.

[0024] like Figure 2 As shown, the support mechanism includes a mounting plate 4 fixedly installed on the side of the mounting column 5. Two mounting blocks 13 are fixedly installed on the top of the mounting plate 4. A rotating shaft 16 is fixedly installed on the side of the two mounting blocks 13 that are close to each other. A Z-shaped support arm 17 is rotatably sleeved on the rotating shaft 16. An inclined support ear 18 is fixedly installed at the end of the Z-shaped support arm 17 away from the mounting block 13. The inclined support ear 18 is installed in conjunction with the corresponding fixing mechanism. An extrusion hole 11 is opened on the vertical side of the Z-shaped support arm 17. A U-shaped block 10 is fixedly installed on the top of the L-shaped rod 6. An extrusion column 12 is fixedly installed on the inner wall of the U-shaped block 10 that is close to each other. One end of the extrusion column 12 passes through the extrusion hole 11. The movement of the four L-shaped rods 6 causes the four U-shaped blocks 10 to move downwards, and the movement of the four U-shaped blocks 10 causes the four extrusion columns 12 to move downwards, thereby extruding the inner walls of the four extrusion holes 11, which in turn causes the four Z-shaped support arms 17 to rotate. The rotation of the four Z-shaped support arms 17 causes the four inclined support ears 18 to rotate to the height of the rotating sleeve 1, thereby facilitating the later positioning support of the rotating sleeve 1 by the Z-shaped support arms 17.

[0025] like Figure 2 and Figure 9 As shown, the extrusion column 12 is located on the side of the rotating shaft 16 away from the mounting column 5, and the extrusion hole 11 is separated from the inner wall of the mounting column 5 by a gap. The advantage of this arrangement is that when the extrusion column 12 moves downward, it will drive the Z-shaped support arm 17 to rotate, which facilitates subsequent auxiliary support.

[0026] like Figure 1As shown, the fixing mechanism includes a vertical support ear 2, which corresponds to the position of the diagonal support ear 18. A bolt 9 is movably installed inside the vertical support ear 2, and a nut 8 is threaded onto the bolt 9. Through the arrangement of the vertical support ear 2, bolt 9, and nut 8, when the positions of the diagonal support ear 18 and the vertical support ear 2 are aligned, the bolt 9 is inserted into the diagonal support ear 18 and the vertical support ear 2, and then fixed by the nut 8, thereby providing support.

[0027] like Figure 1 and Figure 2 As shown, side plates 14 are fixedly installed on both sides of the mounting plate 4. Each of the four side plates 14 has a hole on its top, and a positioning steel nail 15 is installed in each of the four holes. The side plates 14 and the positioning steel nails 15 are used to provide support.

[0028] like Figure 4 and Figure 5 As shown, the limiting mechanism includes a rotating groove 28 formed on the annular side of the mounting column 5. Each of the four mounting plates 4 has an arc-shaped hole 21 on its side. A rotating ring 20 is rotatably mounted within the four arc-shaped holes 21 and the rotating groove 28. Four push rods 29 are fixedly mounted on the top of the rotating ring 20. An arc-shaped column 30 is fixedly mounted on the top of each of the four push rods 29. The sides of the four arc-shaped columns 30 respectively contact the sides of four L-shaped rods 6. Limiting components are installed on each of the four rotating rings 20. The limiting component includes a push rod 22 rotatably mounted on the bottom of the rotating ring 20. A locking rod 23 is rotatably mounted on the end of the push rod 22 away from the rotating ring 20. The side of the locking rod 23... A reset sleeve 26 is fixedly installed on the part, and a reset rod 25 is slidably installed inside the reset sleeve 26. Both ends of the reset rod 25 extend outside the reset sleeve 26. One end of the reset rod 25 is fixedly installed on the side of the mounting post 5. A reset spring 27 is sleeved on the reset rod 25. One end of the reset spring 27 is fixedly installed on the side of the mounting post 5, and the other end of the reset spring 27 is fixedly installed on the side of the reset sleeve 26. An annular groove 7 is opened on the annular side of the cement rod 3. A locking hole 19 is provided on one side of the locking rod 23, which is opened on the inner wall of the groove. One end of the locking rod 23 is slidably installed in the locking hole 19. The locking hole 19 corresponds to the position of the annular groove 7. The four L-shaped rods 6 move downwards, causing the four arc-shaped columns 30 to slowly separate from the four L-shaped rods 6. When the four arc-shaped columns 30 separate from the four L-shaped rods 6 respectively, the four return springs 27 are in a deformed state. Under the action of the four return springs 27, the four return sleeves 26 move. The movement of the four return sleeves 26 drives the four locking rods 23 to move. The four locking rods 23 enter the annular locking groove 7, thereby further limiting the bottom of the cement rod 3, thus facilitating the quick fixation of the cement rod 3.

[0029] like Figure 5As shown, a threaded hole is provided on one side of the inner wall of the rotating ring 20. A stud is threaded into the threaded hole, and one end of the stud extends out of the threaded hole and is fixedly mounted with an L-shaped handle 24. Rotating the L-shaped handle 24 causes it to rotate, thereby causing the stud to rotate and press against the inner wall of the rotating ring 20, thus completing the position limit of the rotating ring 20.

[0030] A manufacturing process for a high-performance cement pole with a bottom end resistant to salt and alkali treatment, the process comprising the following steps: Step 1: Prepare high-quality cement, graded aggregates, suitable admixtures, and standard-compliant steel bars, and measure them accurately for later use; at the same time, clean and inspect the molds and apply release agent to prepare for subsequent production. Step 2: First, make the steel reinforcement into a skeleton and install it into the mold. Then, pour the well-mixed concrete into the mold in layers. After completion, apply anti-salt and alkali coating to the bottom of the cement pole and wrap it with anti-salt and alkali material. Then, steam curing and natural curing are carried out to make it reach the specified strength. Step 3: Conduct a visual inspection of cement pole 3 to ensure that the surface is free of defects; measure its dimensions to ensure that it meets the design requirements; test its compressive and flexural strength, and cement poles that pass the strength test are finished products.

[0031] The working principle and usage process of this invention are as follows: In use, remove the four bolts 9 and four nuts 8 from the four vertical support ears 2. Then, align the rectangular block 32 on the cement rod 3 with the rectangular groove 34 and move it. When the rectangular block 32 enters the rectangular groove 34, the bottom of the cement rod 3 contacts the top of the round seat 35. Under the weight of the cement rod 3, the round seat 35 moves downward. The movement of the round seat 35 causes the four movable blocks 33 to move downward and contact the bottom inner walls of the four movable grooves 36 respectively. The moving spring 37 deforms, and the movement of the four movable blocks 33 causes the four L-shaped rods 6 to move. The movement of the four L-shaped rods 6 causes the four U-shaped blocks 10 to move downward. The movement of the four U-shaped blocks 10... The four extrusion columns 12 are moved downwards, thereby extruding the inner walls of the four extrusion holes 11, which in turn causes the four Z-shaped support arms 17 to rotate. The rotation of the four Z-shaped support arms 17 causes the four inclined support ears 18 to rotate to the height of the rotating sleeve 1. After the inclined support ears 18 rotate, they are in a vertical state. At this time, the four clamping rods 23 correspond to the positions of the annular clamping grooves 7. Then, the rotating sleeve 1 is rotated so that the four vertical support ears 2 contact the four inclined support ears 18 respectively. After inserting the four bolts 9 into the four inclined support ears 18 and the four vertical support ears 2 respectively, they are fixed by the four nuts 8 to provide support. The initial height of the four Z-shaped support arms 17 is low, which facilitates the installation of the cement pole 3. Simultaneously, the four L-shaped rods 6 move downwards, causing the four arc-shaped columns 30 to slowly separate from the four L-shaped rods 6. When the four arc-shaped columns 30 separate from the four L-shaped rods 6 respectively, the four return springs 27 are in a deformed state. Under the action of the four return springs 27, the four return sleeves 26 move. The movement of the four return sleeves 26 drives the four locking rods 23 to move. The four locking rods 23 enter the annular groove 7, thereby further limiting the bottom of the cement rod 3, thus facilitating the quick fixation of the cement rod 3. When disassembling the cement rod 3 later, rotate the L-shaped handle 24 around the mounting column 5 to make the four push rods 22 rotate, thereby causing the four locking rods 23 to retract. Then rotate the L-shaped handle 24 to make it rotate, thereby causing the stud to rotate and press against the inner wall of the rotating ring 20, thus completing the position limit of the rotating ring 20. Then remove the multiple bolts 9 and multiple nuts 8, and move the cement rod 3 upwards to disassemble.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.

A manufacturing process for a high-performance cement pole with bottom end resistant to salt and alkali treatment, applied to the high-performance cement pole with bottom end resistant to salt and alkali treatment as described in claim 1, characterized in that, Includes the following steps: Step 1: Prepare high-quality cement, graded aggregates, suitable admixtures, and standard-compliant steel bars, and measure them accurately for later use; at the same time, clean and inspect the molds and apply release agent to prepare for subsequent production. Step 2: First, make the steel reinforcement into a skeleton and install it into the mold. Then, pour the well-mixed concrete into the mold in layers. After completion, apply anti-salt and alkali coating to the bottom of the cement pole and wrap it with anti-salt and alkali material. Then, steam curing and natural curing are carried out to make it reach the specified strength. Step 3: Conduct a visual inspection of the cement pole (3) to ensure that there are no defects on the surface; measure its dimensions to ensure that it meets the design requirements; test its compressive and flexural strength, and the cement pole with qualified strength is the finished product.
