Description

Technical Field

[0001] This invention relates to the field of pole assembly technology, specifically to a concrete pole flange anti-deviation connection structure and assembly method. Background Technology

[0002] In the fabrication of concrete utility poles, based on actual use, corresponding assembly work is required to bring the poles to a usable state, that is, to the complete operation of a complete tower capable of supporting conductors, equipment, or communication lines. Specifically, the poles are first placed in designated locations on the ground, then grounded, which involves connecting the grounding steel bars at the bottom of the pole to the pre-reserved grounding grid through welding or other methods. Next, accessories are installed, such as conductor crossarms, insulators, and hardware, which need to be installed at the top of the pole. The poles are then lifted and lowered into the pit using hoisting equipment, the pit is compacted and fixed, and finally, vertical alignment is performed. During the above process, holes need to be drilled on the surface of the pole to provide pre-drilled holes for the accessories. Existing drilling equipment for utility poles requires the equipment to be moved to the pole's location before drilling, due to the pole's large mass. However, the uncertainty of the pole's position makes it difficult to achieve perfect perpendicularity between the pole surface and the drill bit. This leads to deviations in the hole's position, potentially causing difficulties in subsequent accessory installation and hindering the pole assembly process.

[0003] Based on this, a concrete pole flange anti-deviation connection structure and assembly method are designed. Summary of the Invention

A U-shaped frame is fixed to the output end of the first hydraulic cylinder. A connector is slidably connected to the end of the U-shaped frame. The connector is fixed to the surface of the arc plate.

[0006] Furthermore, the connector is specifically a buffer tube, the end of the U-shaped frame is inserted into the buffer tube, the surface of the arc plate has a notch, a top rod is fixed to the side of the U-shaped frame, an air plate is fixed to the end of the top rod, an air extraction box is slidably connected to the side of the air plate, an arc plate is fixed to the side of the air extraction box, a sealing sandbag is fixed to the side of the arc plate, a pair of air pipes are connected to the surface of the sealing sandbag, and a ventilation component is connected between the end of the air pipe and the air extraction box. Multiple limiting strips are fixed at the intersection of the adjusting column and the notch.

[0007] Furthermore, the ventilation assembly includes a connecting air cylinder, one end of which is connected to an air pipe and the other end of which is connected to an air extraction box. A pair of blocking blocks are fixed to the side of the air plate, and the ends of the blocking blocks are inserted into the connecting air cylinder to block it.

[0008] Furthermore, the surface of the blockage block is provided with a cavity, one end of which is located inside the connecting cylinder, and the other end is located on the outer side of the connecting cylinder. A piston is inserted into the port located inside the connecting cylinder, and a connecting spring is fixed between the piston and the inner wall of the cavity.

[0009] Furthermore, multiple detection plates are installed in a ring on the side of the output end of the motor assembly. Detection columns are inserted into the ends of the detection plates. A detection spring is fixed between the top of the detection column and the top of the detection plate. The bottom of the detection column is at the same height as the bottom of the output end of the motor assembly. Multiple friction blocks are fixed around the bottom of the detection plate around the detection column, and the friction blocks are in abutting contact with the side of the detection column.

[0010] A concrete pole flange anti-deviation connection structure includes a pair of clamp heads. The inner surface of the clamp head is provided with a notch that matches the ribs on the surface of the reinforcing bar. A fixing plate is fixed to the end of the clamp head. Bolts are inserted into the surface of the fixing plate. The flange surface connected to the bolts has threaded holes. The fixing plate can be fixed to the flange by the engagement of the bolts with the threaded holes.

[0011] Furthermore, the structure used for assembling the flange anti-deviation connection structure includes a gasket, the two sides of which are set as inclined surfaces to facilitate the movement of the reinforcing cage. A horizontal rail is provided above the gasket, and a slider is slidably connected inside the horizontal rail. A lead screw is engaged and inserted through the side of the slider. A servo motor is provided at the end of the lead screw and is installed at the end of the horizontal rail. An infrared ranging sensor is installed at the bottom of the slider.

[0013] Furthermore, the infrared ranging sensor is connected to an external microcomputer via an electrical signal to detect and calculate whether the topmost rebar of the horizontally placed rebar cage is in a horizontal state. The specific process is as follows: During detection, the microcomputer controls the servo motor to start via an electrical signal. The servo motor drives the lead screw to rotate. When the lead screw rotates, it meshes with the slider for transmission. The slider drives the infrared ranging sensor at the bottom to move synchronously. The infrared ranging sensor is located directly above the topmost rebar of the horizontally placed rebar cage. When the infrared ranging sensor moves, it emits infrared light to determine the current detection distance and sends the current detection distance to the microcomputer. The microcomputer then determines whether the detected rebar is bent.

[0014] Furthermore, the microcomputer is equipped with an analysis module: The analysis module receives distance data sent by the infrared ranging sensor and distinguishes between interference data and actual data. Interference data is the distance of the spiral steel wire covering the surface of the rebar, while actual data is the distance of the rebar itself. Since the diameter of the steel wire is constant, the data fluctuation reflected by the interference data is a constant arc in the coordinate system compared to the actual data. Based on this, the interference data can be identified and grouped. Different groups of interference data are the actual data. The analysis module then groups the actual data between different groups of interference data and calculates the average value. If the reinforcing bars remain straight, the average value of the actual data in different groups will be the same; if the reinforcing bars are bent, the average value of the actual data in different groups will be different.

[0015] This invention provides a concrete pole flange anti-deviation connection structure and assembly method. It has the following beneficial effects: 1. The anti-deviation connection structure and assembly method of this concrete pole flange, by setting an adjusting column, during the drilling process, when the bottom end of the motor assembly output is tilted relative to the pole surface, the angle of the motor assembly is adjusted by the adjusting column in conjunction with the arc plate. The static friction between the adjusting column and the arc plate restricts the further rotation of the motor assembly. Then, the operator controls the motor assembly to move downward and start it, and the output end of the motor assembly is gradually drilled into the pole. After drilling to the specified depth, it is taken out, completing the drilling operation. This ensures that the corresponding index values ​​of the drilling position are accurate, ensuring smooth installation of subsequent accessories, and does not require adjustment of the pole position, which is beneficial to the pole assembly process.

[0016] 2. The anti-deviation connection structure and assembly method of the concrete pole flange, by setting a clamp head, can pull and fix the bent steel bars on the steel cage through the clamp head and fixing plate, thereby restoring them to a straight state. This ensures that when drilling holes in the pole made based on the steel cage, the steel bars remain in a straight state, making it difficult to interfere with the drilling operation.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Combined with appendix Figure 1-10 In one embodiment of the present invention, a method for assembling concrete utility poles includes the following steps: The first step is to arrange the poles in order on the ground; The second step is to install the accessories on the pole. The accessories include conductor crossarms, insulators, and hardware. The third step is hoisting, in which the utility pole is vertically hoisted into the pit using hoisting equipment, and then the pit is compacted and fixed. The fourth step is inspection, which involves checking the verticality of the poles after hoisting to ensure that they are installed vertically. The second step of accessory installation includes equipment frame 1, with a lifting slide rail 2 installed at the top of the equipment frame 1. A lifting sliding component 21 is slidably connected in the track of the lifting slide rail 2. A fixing block 22 is fixedly connected to the side of the lifting sliding component 21. An adjusting column 23 is rotatably connected to the side of the fixing block 22. A motor assembly 3 is fixedly connected to the end of the adjusting column 23 away from the fixing block 22. A pair of arc plates 30 are slidably provided on the side of the adjusting column 23. A pair of positioning frames 11 are symmetrically installed on the top of the equipment frame 1 based on the adjusting column 23. A first hydraulic cylinder 12 is fixedly connected to the top of the positioning frame 11. A U-shaped frame 13 is fixedly connected to the output end of the first hydraulic cylinder 12. A connector 14 is slidably connected to the end of the U-shaped frame 13. The connector 14 is fixedly connected to the surface of the arc plate 30. When actually drilling holes in the surface of a utility pole, the entire drilling equipment is first moved to one side of the pole to be drilled, and the output end of the motor assembly 3 is aligned with the position to be drilled on the pole. Then the position of the equipment frame 1 is fixed. In some embodiments of this application, the position of the equipment frame 1 can be fixed by pressing down with a heavy object. The motor assembly 3 includes at least a motor for outputting torque and a mounting frame. The motor assembly 3 can drive the lower output end to rotate at high speed. During the drilling process, the lifting sliding member 21 can drive the motor assembly 3 to move downward through the fixing block 22 and the adjusting column 23. The lifting sliding member 21 includes a braking structure that cooperates with the lifting slide rail 2, such as a cylinder-driven brake block that squeezes and brakes the lifting slide rail 2. During the drilling process, when the bottom end of the motor assembly 3 is tilted relative to the pole surface (i.e., the angle between the axis of the motor assembly 3 and the pole axis is not 90 degrees), the operator adjusts the angle of the motor assembly 3, thereby adjusting the angle of the adjusting column 23 and the fixing block 22. The adjustment stops when the angle between the axis of the motor assembly 3 and the pole axis is 90 degrees. Then, the first hydraulic cylinder 12 is activated, and the output end of the first hydraulic cylinder 12 moves the U-shaped frame 13 and the connecting piece 14, causing the arc plate 30 to further press the adjusting column 23. Static friction is generated between the adjusting column 23 and the arc plate 30, limiting the further rotation of the motor assembly 3. Then, the operator controls the motor assembly 3 to move downward and start it. The output end of the motor assembly 3 gradually drills into the pole. After drilling to the specified depth, it is removed, completing the drilling operation. The above-mentioned angle adjustment of the motor assembly 3 ensures that the corresponding index values ​​of the drilling position are accurate, ensuring smooth installation of subsequent accessories and eliminating the need to adjust the pole position, which is beneficial to the pole assembly process.

[0021] It should be noted that the above implementation method is for cylindrical poles. If it is for tapered poles, the angle between the output axis of the motor assembly 3 and the pole axis needs to be kept constant.

[0022] The connector 14 is specifically a buffer tube. The end of the U-shaped frame 13 is inserted into the buffer tube. The surface of the arc plate 30 has a notch 301. A top rod 15 is fixedly connected to the side of the U-shaped frame 13. An air plate 16 is fixedly connected to the end of the top rod 15. An air extraction box 17 is slidably connected to the side of the air plate 16. An arc-shaped piece 18 is fixedly connected to the side of the air extraction box 17. A sealing sandbag 19 is fixedly connected to the side of the arc-shaped piece 18. A pair of air pipes 163 are connected to the surface of the sealing sandbag 19. A ventilation component is connected between the end of the air pipe 163 and the air extraction box 17. Multiple limit strips 231 are fixedly connected at the intersection of the adjusting column 23 and the notch 301. When adjusting the angle of the motor assembly 3, the U-shaped frame 13 is first controlled to release the pressure on the connector 14. The connector 14 is specifically a buffer tube. Therefore, the end of the U-shaped frame 13 is located at the opening of the buffer tube. After adjusting the angle of the motor assembly 3, the U-shaped frame 13 is controlled to move into the buffer tube. During this process, the U-shaped frame 13 drives the top rod 15 to move synchronously. The top rod 15 drives the sealing sandbag 19 to move synchronously through the air extraction box 17 and the arc plate 18. When the sealing sandbag 19 passes through the notch 301, it will press against the limiting strip 231 on the surface of the adjusting column 23. Furthermore, the sealing sandbag 19 is filled with plastic particles. When the inside is full of air, the particles can slide freely. When the air inside is extracted, the particles inside the sealing sandbag 19 are squeezed together tightly, and the friction between the particles increases sharply. The whole can no longer make relative displacement. The originally soft bag instantly becomes as hard as a stone. During the process of inserting the U-shaped frame 13 into the innermost part of the buffer tube, as the sealing sandbag 19 presses against the limiting strip 231 on the surface of the adjusting column 23, the position of the air extraction box 17 stabilizes. Then, as the air plate 16 moves further, the air plate 16 moves within the air extraction box 17, increasing the space of the area connected to the ventilation component inside the air extraction box 17, thus reducing the air pressure. Therefore, the air inside the sealing sandbag 19 is extracted through the air pipe 163 and the ventilation component, causing the air inside the sealing sandbag 19 to be removed and hardened. When the U-shaped frame 13 stops moving, the sealing sandbag 19, in conjunction with the limiting strip 231, further fixes the angle of the adjusting column 23, reinforcing the stability of the motor assembly 3 and helping to maintain the stability of the drilling process of the motor assembly 3.

[0023] In some embodiments of this application, the ventilation assembly includes a connecting air cylinder 162, one end of which is connected to an air pipe 163, and the other end is connected to an air extraction box 17. A pair of blocking blocks 161 are fixed to the side of an air plate 16, and the ends of the blocking blocks 161 are inserted into the connecting air cylinder 162 to block it. When the air plate 16 moves inside the air extraction box 17, the air plate 16 drives the blocking blocks 161 to move synchronously. While the blocking blocks 161 are not disengaged from the connecting air cylinder 162, the connecting air cylinder 162 remains blocked. Therefore, the sealing sandbag 19 will not be immediately de-aired and hardened after being pressed against the limiting strip 231. After being fully compressed and contacted with the limiting strip 231, the blocking block 161 disengages from the connecting air cylinder 162, and the sealing sandbag 19 begins to be evacuated and hardened. The entire process involves full contact followed by hardening and fixation, which helps to optimize the braking effect between the sealing sandbag 19 and the limiting strip 231. Furthermore, a cavity 1611 is formed on the surface of the blocking block 161. One end of the cavity 1611 is located inside the connecting air cylinder 162, and the other end is located on the outer side of the connecting air cylinder 162. A piston 1613 is inserted into the end located inside the connecting air cylinder 162, and a connecting spring 1 is fixed between the piston 1613 and the inner wall of the cavity 1611. 612; When the U-shaped frame 13 stops moving, the end of the U-shaped frame 13 extends into the deepest part of the buffer tube to transmit the pressure torque. The surface of the buffer tube is provided with air leakage holes to prevent the internal gas pressure from obstructing the movement of the end of the U-shaped frame 13. When the air plate 16 stops moving, the inside of the extraction box 17 is divided into a negative pressure area and a high pressure area, separated by the air plate 16. When the drilling is completed and the U-shaped frame 13 is reset, the high pressure area pushes the air plate 16 to reset within the extraction box 17. During the reset process, the blocking block 161 will re-insert into the connecting air cylinder 162. After the blocking block 161 re-inserts into the connecting air cylinder 162, the low pressure area... The reduction in space causes the negative pressure to disappear, and the residual air in the low-pressure area is further squeezed into the cavity 1611. The resulting gas pressure pushes the piston 1613 to pull the connecting spring 1612, causing it to deform. In other words, the piston 1613 is opened, opening the cavity 1611. The residual air in the low-pressure area flows back into the sealing sandbag 19 through the connecting air cylinder 162 and air pipe 163, thereby releasing the hardening of the sealing sandbag 19 and facilitating the re-deformation contact between the motor assembly 3 and the limit strip 231 after the angle is readjusted. It should be noted that the high-pressure area continuously pushes the air plate 16 to facilitate the reset of the air plate 16 in the air extraction box 17.

[0024] In some embodiments of this application, multiple detection plates 31 are annularly mounted on the side of the output end of the motor assembly 3. Detection posts 32 are inserted into the ends of the detection plates 31. A detection spring 33 is fixed between the top of the detection post 32 and the top of the detection plate 31. The bottom of the detection post 32 is at the same height as the bottom of the output end of the motor assembly 3. Multiple friction blocks 34 are fixed around the detection post 32 at the bottom of the detection plate 31, and the friction blocks 34 press against the side of the detection post 32. When detecting whether the angle between the axis of the output end of the motor assembly 3 and the axis of the pole remains perpendicular, the bottom of the output end of the motor assembly 3 is moved to the surface of the pole. Then, the motor assembly 3 is started, and the output end of the motor assembly 3 drives the detection plates 31 to rotate. When the detection plates 31 rotate, they drive the detection posts 32 to rotate synchronously. When the axis of the output end of the motor assembly 3... When the line is perpendicular to the pole axis, the bottom of the detection column 32 is at the same height as the bottom of the output end of the motor assembly 3, so the rotation of the detection column 32 is not obstructed. When the output end axis of the motor assembly 3 is not perpendicular to the pole axis, the rotation of the detection column 32 will be obstructed. Since both the pole surface and the bottom of the detection column 32 are curved surfaces, the detection column 32 will be squeezed and moved relative to the detection plate 31 when it is obstructed. It will move back and forth in conjunction with the detection spring 33, and produce relative displacement with the friction block 34, resulting in abnormal noise. Based on this, the operator judges that the angle of the motor assembly 3 needs to be adjusted. After the adjustment is completed, the detection plate 31 is removed from the output end of the motor assembly 3 to avoid affecting the drilling operation. The above detection can help the operator judge whether the output end axis of the motor assembly 3 is adjusted to be perpendicular to the pole axis, which is convenient for use.

[0025] In some embodiments of this application, during the pole manufacturing process, including the installation of flanges at the ends of the reinforcing cage, existing installation methods for thinner reinforcing bars mostly involve upsetting. Depending on different customer or process requirements, welding or other connection methods can also be used. This involves passing the end of the reinforcing cage through the flange and cold-upsetting it into a rounded shape using a hydraulic upsetting machine. However, in actual operation, the reinforcing bars in the cage are prone to bending due to their own weight, especially in longer cages. Bending reinforcing bars are difficult to straighten after cold upsetting. After filling with concrete and completing centrifugal molding and steam curing, when drilling holes in the surface of the assembled pole, the bent reinforcing bars may deviate from their original position, potentially interfering with the drilling at the predetermined drilling depth. Therefore, a concrete pole flange anti-deviation connection structure is designed. It includes a pair of clamp heads 4, the inner surface of the clamp head 4 is provided with a notch that matches the ribs on the surface of the steel bar, the end of the clamp head 4 is fixedly connected to a fixing plate 41, and bolts are inserted into the surface of the fixing plate 41; the flange surface connected to the bolts is provided with threaded holes, and the fixing plate 41 can be fixed to the flange by the engagement of the bolts and the threaded holes. The structure for the anti-deviation connection of the assembly flange includes a gasket 5. The two sides of the gasket 5 are set as inclined surfaces to facilitate the movement of the reinforcing cage. A horizontal rail 6 is set above the gasket 5. A slider 61 is slidably connected inside the horizontal rail 6. A lead screw 62 is inserted and meshed on the side of the slider 61. A servo motor is set at the end of the lead screw 62. The servo motor is installed at the end of the horizontal rail 6. An infrared ranging sensor is installed at the bottom of the slider 61. A pair of connecting frames 63 are fixed to both sides of the slider 61. A second hydraulic cylinder is installed at the bottom of the connecting frame 63. A linkage frame 64 is fixed to the output end of the second hydraulic cylinder. A straightening inclined block 65 is fixed to the end of the linkage frame 64. The top of the straightening inclined block 65 is at the same height as the bottom of the topmost reinforcing bar of the horizontally placed reinforcing cage. The straightening inclined block 65 is set in a trapezoidal shape. In use, the infrared ranging sensor is connected to an external microcomputer via an electrical signal to detect and calculate whether the topmost rebar of a horizontally placed rebar cage is horizontal. The specific process is as follows: During detection, the microcomputer controls the servo motor to start via an electrical signal. The servo motor drives the lead screw 62 to rotate. When the lead screw 62 rotates, it engages with the slider 61, which in turn drives the infrared ranging sensor at its bottom to move synchronously. The infrared ranging sensor is positioned directly above the topmost rebar of the horizontally placed rebar cage. As the infrared ranging sensor moves, it emits infrared light to determine the current detection distance and simultaneously sends this distance to the microcomputer. The microcomputer then determines whether the detected rebar is bent. If the rebar is found to be bent, the microcomputer controls the second hydraulic cylinder to start. The second hydraulic cylinder, through the linkage frame 64, drives the straightening block 65 to move towards the current rebar, thus correcting the bending. When the reinforcing bars come into contact, they are lifted by the inclined surface and stopped when the reinforcing bars slide to the top of the straightening block 65. At this time, the bent reinforcing bars are lifted and tend to return to a straight state. The above process requires controlling the position of the straightening block 65 to avoid being blocked by the steel wire welded on the reinforcing cage. After that, the workers install a pair of clamp heads 4 on the end of the reinforcing bars and align them with the flange. During installation, the ribs on the surface of the reinforcing bars need to be embedded into the recesses on the arc-shaped inner surface of the clamp head 4, with the ribs and recesses intersecting. Then, the fixing plate 41 is fixed to the flange with bolts. In this process, the reinforcing bars are pulled and fixed by the bolts and thus return to a straight state. There is a gap between the fixing plate 41 and the flange to reserve space for pulling. Based on the above, the reinforcing cage can be rotated and the clamp heads 4 are installed on each of the reinforcing bars that make up the reinforcing cage. After that, the reinforcing cage can be moved to the station of the hydraulic upsetting machine for cold upsetting.

[0026] In some embodiments of this application, the analysis module receives distance data sent by an infrared ranging sensor and distinguishes between interference data and actual data. The interference data is the detected distance of the spiral steel wire covering the surface of the reinforcing bar, while the actual data is the distance of the reinforcing bar itself. Since the diameter of the steel wire is constant, compared to the actual data, the data fluctuations reflected by the interference data appear as a constant arc within the coordinate system, such as... Figure 14As shown, the length of the reinforcing bar is defined as the X-axis, and the distance data is defined as the Y-axis. One set of interference data reflects the function curve. Based on this, the interference data can be identified and grouped. The spiral steel wire is spirally welded to the surface of the reinforcing cage. The interference data and the actual data are recorded alternately. Therefore, the interference data in different groups are the actual data. The analysis module then groups the actual data between different groups of interference data and calculates the average value. If the reinforcing bar remains straight, all the detected actual data remain the same, and the average value of the actual data in different groups is the same. If the reinforcing bar is bent, the detected actual data will differ, and the average value of the actual data in different groups will be different.

The anti-deviation connection structure for concrete pole flanges according to claim 8, characterized in that: The infrared ranging sensor is connected to an external microcomputer via an electrical signal. It is used to detect and calculate whether the topmost rebar of a horizontally placed steel cage is in a horizontal state. The specific process is as follows: During detection, the microcomputer controls the servo motor to start via an electrical signal. The servo motor drives the lead screw (62) to rotate. When the lead screw (62) rotates, it meshes with the slider (62) for transmission. The slider (62) drives the infrared ranging sensor at the bottom to move synchronously. The infrared ranging sensor is located directly above the topmost rebar of the horizontally placed steel cage. When the infrared ranging sensor moves, it emits infrared light to determine the current detection distance and sends the current detection distance to the microcomputer. The microcomputer then determines whether the detected rebar is bent.

10. The anti-deviation connection structure for concrete pole flanges according to claim 9, characterized in that: The microcomputer is equipped with an analysis module: The analysis module receives distance data sent by the infrared ranging sensor and distinguishes between interference data and actual data. Interference data is the distance of the spiral steel wire covering the surface of the rebar, while actual data is the distance of the rebar itself. Since the diameter of the steel wire is constant, the data fluctuation reflected by the interference data is a constant arc shape in the coordinate system compared to the actual data. Based on this, the interference data can be identified and grouped. The spiral steel wire is spirally welded to the surface of the rebar cage, and the interference data and actual data are recorded alternately. Therefore, different groups of interference data are actually data. The analysis module then groups the actual data between different groups of interference data and calculates the average value. If the reinforcing bars remain straight, the average value of the actual data in different groups will be the same; if the reinforcing bars are bent, the average value of the actual data in different groups will be different.
