Description

Technical Field

[0001] This invention belongs to the field of communication construction equipment technology, specifically relating to a pole erecting machine for communication lines. Background Technology

[0002] The communication line pole erecting machine is a specialized lifting machinery used in the field of communication engineering construction for the erection, installation, and positioning of communication poles. It mainly realizes the entire process of communication poles from a horizontal position, through tilting and lifting, and gradually straightening to a vertical position. After the pole is accurately positioned, it is then used in conjunction with the excavation, backfilling, and compaction of the foundation pit to complete the burial and fixation of the pole, providing a stable support foundation for the erection of communication lines, the laying of optical cables, and the installation of communication equipment.

[0003] For example, Chinese patent CN109537978A discloses a pole erector for communication lines, including a vehicle floor. The pole is characterized by a rotating shaft connected to one side of the floor, an upper end of which is connected to a driver's cab. A battery pack is located on one side of the driver's cab, and a transformer is located above the battery pack. An operating platform is located on one side of the driver's cab, and a staircase is located on one side of the operating platform. A lifting arm is connected to the middle of the operating platform, and the lifting arm is connected to the lower arm of the pole erector. The lower arm is connected to a rotary bearing, which connects to the upper arm and a telescopic arm of the pole erector. The upper arm is equipped with a drilling device, the lower end of which is connected to a drill bit. A hook is connected to the telescopic arm, and a hydraulic device is connected to the other side of the operating platform. The crane operates via a control panel to retract the upper arm of the pole erecting machine and extend the telescopic boom. The telescopic boom is then used to lift the utility pole and place it into a pre-drilled hole. The lifting device and the upper and lower arms of the pole erecting machine are powered by a hydraulic transmission system, requiring no external force. The operator only needs to control the direction to place the pole into the pre-dug hole. The tracked drive allows for travel and construction in various terrains, and the battery-powered searchlights effectively improve lighting conditions in the construction environment.

[0004] For example Figure 15 In the existing technology shown, the use of a tripod pole erecting machine is also a commonly used equipment for pole erection. A tripod is used to support the pole next to the pit, with the center aligned with the pit. A wire rope clamp is used to fix the upper part of the pole. A winch is used to tighten the wire rope, and levers and pulleys are used to slowly erect the pole.

[0005] The pole erecting machines and triangular pole erecting machines used in the aforementioned communication pole erection construction both employ the method of first lifting and positioning the pole before lowering it into place. However, due to the lack of stable vertical guidance constraints while the pole is in the hoisted state, its verticality is difficult to control precisely. This necessitates manual on-site assistance for verticality correction and positioning during the subsequent pole erection process. Close-range operation by workers poses significant safety hazards, and relying on manual pushing and correction methods makes it difficult to achieve an ideal vertical installation state for the pole, significantly impacting both erection accuracy and construction safety. Summary of the Invention

[0006] To address the problems of existing technologies, such as the lack of reliable vertical guidance during pole erection, insufficient verticality control precision, the need for close-range manual correction, safety risks, and difficulty in ensuring pole installation accuracy, thus affecting construction quality and operational safety, this invention provides a pole erecting machine for communication lines. Throughout the entire process of the pole gradually transitioning from a horizontal to a vertical position, a limiting unit provides continuous wrapping constraint and guiding support along the erection direction to the outside of the pole.

[0013] The pole erecting machine for communication lines of the present invention has the following advantages compared with the prior art: I. Addressing the issues of existing communication line poles lacking reliable vertical guidance during hoisting, resulting in insufficient verticality control precision, requiring close-range manual correction, posing safety risks, and hindering pole installation accuracy, thus affecting construction quality and operational safety, this invention eliminates reliance on traditional hoisting equipment during pole erection. Throughout the pole's transition from a horizontal to a vertical position, a limiting unit provides continuous wrapping constraint and guiding support along the erection direction, preventing lateral shifts, swaying, or tilting during rotation and erection. This stabilizes the pole's trajectory, controlling verticality during erection and improving the final verticality accuracy of the installed pole. This guiding and limiting method can reduce the need for construction workers to manually guide and correct the pole within the pole erection area, thereby reducing safety hazards for personnel working within the pole's range of motion and making the pole erection process safer. Simultaneously, this invention allows the pole to be released and installed only after it has been adjusted to a preset vertical position, ensuring the pole is vertical when it is in place, reducing the workload of subsequent secondary corrections, and improving the regularity and consistency of the pole installation.

[0014] II. This invention, through the coordinated design of the drive unit and the step-by-step control unit, enables sequential control of the first clamping unit's operation prior to the second clamping unit, under continuous drive. Specifically, it first releases the support from the bottom of the pole, allowing the pole to fall smoothly into the pre-dug pit under its own weight. In this state, temporary support can be provided for the pole. After the bottom is fixed and limited, the guiding constraint on the pole's sidewalls is released, thus achieving a step-by-step operation process of first entering the pit, then providing temporary support, and finally releasing the lateral constraints. Using this sequential control method, the sidewalls of the pole are always subject to lateral guiding constraints throughout the entire construction phase, from vertical erection to completion of installation. This suppresses lateral swaying and tilting of the pole during periods of stress change, such as when the pole enters the pit or undergoes temporary support. This helps maintain the pole's posture stability throughout the installation process, ensuring good verticality before the lateral constraints are released, thereby improving the positioning accuracy and construction reliability of the pole installation.

[0015] Third, this invention uses a drive unit, a first clamping unit, a second clamping unit, and a step-by-step control unit to achieve the above-mentioned step-by-step timing sequence. Compared with the method of relying on the electronic control system, sensor system, or hydraulic control system for staged command control, it does not require additional configuration of electrical control modules, position detection elements, and program logic units. In field construction, humid environments, or complex working conditions, it is less prone to problems such as circuit failure, signal interference, or program abnormalities, and the structural operation stability is stronger. At the same time, this mechanically triggered timing sequence directly realizes the sequence of actions through the mechanical linkage between components. The action response is consistent and is not prone to timing disorder due to control delay or signal error. It can ensure that the steps of the pole entering the pit, bottom backfilling and compaction, and lateral constraint release are strictly executed in the preset order, reducing the risk of pole tilting caused by action misalignment.

[0016] IV. In this invention, the area of ​​the base plate is set to be less than half the cross-sectional area of ​​the third arc-shaped plate. Simultaneously, the driving timing of the driving unit is configured such that after the first loosening unit is driven by the driving unit to rotate the third arc-shaped plate to the 90° opening position, the second loosening unit is then controlled to gradually open the fourth arc-shaped plate. Through the coordinated setting of the above area ratio and action interval, the third arc-shaped plate and the base plate can disengage from the bottom of the pole before the rotation angle reaches 90°, thereby relieving the supporting effect on the bottom of the pole. This structural arrangement allows the bottom of the pole to be lowered and fall into the pit earlier, reserving sufficient action intervals and operation time for subsequent temporary support operations on the pole, which helps ensure a smooth and controllable descent of the pole. In summary, this invention, through vertical guidance constraints on the pole throughout the entire process, step-by-step timing control of entering the pit before releasing the limit, a reliable triggering method based on pure mechanical linkage, and a reasonable combination of the supporting structure area and the action interval, can ensure that the pole maintains a stable posture and is not prone to tilting throughout the entire erection process. This is beneficial for improving the verticality and positioning accuracy of the pole installation, reducing manual close-range correction operations, lowering construction safety hazards, and eliminating the need for secondary correction procedures in the later stages, thus ensuring a stable and reliable pole erection process.

[0018] The following are specific implementation cases and appendices. Figures 1 to 14 The present invention will be further described, but the present invention is not limited to these embodiments.

[0019] Example 1 The technical solution of this invention is mainly applicable to the on-site erection and burial of communication line poles. It can be used for engineering operations such as communication power poles, optical cable poles, rural and urban line renovation, park weak current poles, and pole installation for outdoor communication base stations. It can complete pole transportation, posture adjustment and vertical burial without hoisting conditions, and meet the installation and construction needs of communication line infrastructure under different working conditions.

[0020] For details, please refer to [link / reference]. Figures 1 to 10 As shown, a pole erecting machine for communication lines is used to erect poles 8. Pole 8 is a commonly used pole for communication lines. In this embodiment, pole 8 is set to be a 6-8 meter pole. This pole erecting machine includes: a power unit 2, a limiting unit 3, a drive unit 4, a first clamping unit 5, a second clamping unit 6, and a step-by-step control unit 7. The power unit 2 is located below the pole body 8, and its core function is to provide power support for the transition between the horizontal and vertical states of the pole body 8, enabling the pole body to be erected smoothly. The limiting unit 3 is located on the power unit 2, used to support the bottom end of the pole body 8, and to guide and limit the side wall of the pole body 8 during the erection process, ensuring the stability of the pole body's posture. The drive unit 4 is located on the limiting unit 3, serving as the power source for the entire clamping action, providing driving force for the actions of the first and second clamping units. The first clamping unit 5 and the second clamping unit 6 are respectively located on the limiting unit 3, and they respectively control the release of the bottom end support and the side wall limit. The step-by-step control unit 7 is located on one side of the second clamping unit 6, used to coordinate the timing actions of the first clamping unit 5 and the second clamping unit 6, ensuring that the action sequence conforms to the construction logic.

[0021] The drive unit 4 controls the first clamping unit 5 and the second clamping unit 6 to move sequentially through the step control unit 7, so that the limiting unit 3 first releases the support of the bottom end of the rod 8, and then releases the guide limit on the side wall of the rod 8. Combined with the full-process guiding effect of the limiting unit, the rod 8 always maintains vertical guidance during the erection and lowering process, without the need for additional manual correction.

[0022] This invention eliminates the need for traditional hoisting equipment during pole erection. Throughout the transition of pole 8 from a horizontal to a vertical state, the limiting unit 3 provides continuous and reliable constraint, limiting, and guiding positioning, effectively ensuring stable and controllable pole posture and improving verticality control accuracy during pole erection. It also eliminates the need for manual close-range correction and pole placement operations, reducing safety risks associated with high-altitude and close-range operations, making the work safer and more efficient. Furthermore, by releasing and embedding pole 8 only after it has reached the preset vertical posture, it achieves an immediate vertical erection, improving pole embedding verticality and installation accuracy, ensuring neat and stable pole embedding, and guaranteeing the overall construction quality and subsequent operational reliability of the communication line.

[0023] Main references Figure 1 , Figure 2 , Figures 5 to 7 As shown, the limiting unit 3 includes: a bracket 301, a first square base 302, a first arc-shaped plate 303, a second square base 304, a second arc-shaped plate 305, a third arc-shaped plate 306, a base plate 307, and a fourth arc-shaped plate 308. The bracket 301 is fixed to the power unit 2, serving as the mounting base for the limiting unit, and is divided into a feeding end and an opposite end arranged opposite each other.

The bottom support plate 307 is fixed to the outer wall of the third arc-shaped plate 306, that is, the bottom support plate 307 is located on the side wall of the third arc-shaped plate 306 away from the direction of the fourth arc-shaped plate 308. Its core function is to directly support the bottom end of the rod 8. The area of ​​the bottom support plate 307 is less than half of the cross-sectional area of ​​the third arc-shaped plate 306. Combined with the driving sequence of the driving unit 4, the first loosening unit 5, driven by the driving unit 4, first drives the third arc-shaped plate 306 to rotate in the opening direction. After it has rotated 90°, the second loosening unit 6 then drives the fourth arc-shaped plate 308 to gradually open. The fourth arc-shaped plate 308 is divided into two groups and is controlled to rotate on two groups of second arc-shaped plates 305 respectively. The rotation can release the side wall limit.

[0024] By coordinating the area ratio and action timing of the base plate 307 and the third arc-shaped plate 306, the third arc-shaped plate 306 and the base plate 307 can disengage from the bottom of the pole 8 before the rotation angle reaches 90°, thus releasing the support for the bottom of the pole in advance. This structural arrangement allows the bottom of the pole 8 to fall earlier and enter the preset pit, providing sufficient action intervals and operation time for the temporary support operation of the pole 8, thereby making the pole's descent process more stable and the attitude control more reliable.

The insertion rod 706 is controlled to be inserted into the inner cavity of the insertion hole 704. Its core function is to limit the side block 703 and the second rack 607 and control the timing of the action of the second release unit 6.

[0031] The step control unit 7 further includes: a vertical plate 705, a first connecting seat 707, a second connecting seat 708, a connecting rod 709, and a spring 710. The vertical plate 705 is vertically mounted on the bracket 301, serving as the mounting support base for the insertion rod 706, and the insertion rod 706 is slidably inserted into the top of the vertical plate 705. The first connecting seat 707 is fixed to the end of the insertion rod 706, used to connect the connecting rod 709 and transmit driving force. The second connecting seat 708 is fixed to the end of the U-shaped seat 403. It is used to connect the U-shaped seat 403 and the linkage rod 709; the linkage rod 709 is rotatably connected between the first connecting seat 707 and the second connecting seat 708 to realize the linkage between the U-shaped seat 403 and the insertion rod 706 and transmit the action signal; the spring 710 is sleeved on the insertion rod 706, and its two ends are respectively connected to the first connecting seat 707 and the outer wall of the upright plate 705, to provide the insertion rod 706 with the reset elastic force, so as to ensure that the insertion rod 706 is stably inserted into the insertion hole 704 in the initial state.

[0032] In the initial state, when the rod 8 is locked between the first arc plate 303 and the third arc plate 306, and the second arc plate 305 and the fourth arc plate 308, and the pin 404 is in the inner cavity of the slide groove 702 and does not apply driving force to the side plate 701, the insertion rod 706 is inserted into the insertion hole 704 to form a reliable limiting constraint on the side plate 701, preventing the second rack 607 from moving downward and the second gear 603 from rotating, thus preventing the rotation of the second gear 603 from triggering the opening of the fourth arc plate 308. This ensures that the fourth arc plate 308 and the second arc plate 305 remain tightly engaged in this state, providing stable guidance and limiting for the side wall of the rod 8, ensuring the locking stability of the overall structure, providing safety for the horizontal to vertical posture conversion of the rod 8, and preventing the rod from shifting during the conversion process.

[0033] When the pin 404 moves to the end of the inner cavity of the slide groove 702, the linkage rod 706 disengages from the inner cavity of the insertion hole 704. The pin 404 continues to descend and drives the side block 703 and the second rack 607 to descend synchronously, thereby realizing the action sequence control of the first connecting arm 504 rotating before the second connecting arm 604. This follows the construction logic of first releasing the bottom support and then releasing the side wall limit, avoiding the rod tilting due to the disorder of the action sequence.

[0034] This invention, through the coordinated arrangement of the drive unit 4 and the step-by-step control unit 7, enables sequential control of the first clamping unit 5's priority over the second clamping unit 6 under continuous drive of the drive unit 4. Specifically, the bottom support of the pole 8 is first released, allowing the pole to fall smoothly into the pre-set pit under its own weight and complete temporary support. After the bottom is fixed and limited, the side wall guide constraint is released, forming a step-by-step operation process of first entering the pit, then providing support, and finally releasing the side constraints. This process design closely matches the actual on-site construction, ensuring the stability of the pole's posture while allowing sufficient operation time for temporary support.

[0035] Meanwhile, throughout the entire process from erection and straightening to installation, the sidewall of pole 8 remains within the lateral constraint range. This effectively suppresses swaying, tilting, and offset during stress changes such as pit descent and support, ensuring that it remains nearly vertical before the lateral constraint is released. Structurally, this avoids the verticality deviation caused by timing errors in traditional poles, significantly improving installation positioning accuracy and construction reliability.

[0036] The aforementioned temporary support can adopt existing mature rapid support methods, such as using wooden or steel wedges to quickly wed the rod between the rod and the pit wall. This method can complete the temporary limiting and fixing of the rod within a few seconds, meeting the rapid support requirements within the mechanism's action sequence, without the need to build complex temporary supports.

[0037] This invention employs a purely mechanical structure for timing control, eliminating the need for electrical control and hydraulic drives. This results in a simple structure and high reliability. Compared to various electrical and sensor-based control systems, it effectively resists interference from environmental factors such as humidity, dust, and construction vibrations, effectively avoiding signal drift, line faults, or program malfunctions, thus offering greater adaptability to different working conditions. Furthermore, the timing sequence of actions in this application is directly triggered by mechanical linkage, ensuring timely and accurate response and good timing consistency. This guarantees a stable and reliable sequence of actions: the pole first falls into the pit, then temporary support is provided, and finally lateral constraints are released. This effectively prevents pole tilting or instability due to misalignment, improving the safety and accuracy of pole erection. Moreover, it eliminates the need for additional electrical and hydraulic components, reducing equipment manufacturing and maintenance costs.

The first mounting plate 201 and the second mounting plate 205 are provided in two sets, serving as the mounting support base for each component of the power unit. The first rotating shaft 202 is rotatably disposed between the two sets of first mounting plates 201, serving as the rotation axis of the swing arm 203 and providing support for its rotation. The second rotating shaft 206 is rotatably disposed between the two sets of second mounting plates 205, providing support for the sleeve 207 and the first servo electric cylinder 208. The swing arms 203 are divided into two groups and fixed at both ends of the first rotating shaft 202. Their core function is to drive the cross frame 210 and the limiting unit 3 to rotate synchronously, thereby realizing the posture conversion of the rod body 8. The connecting shaft 204 is fixed at the ends of the two groups of swing arms 203 and is used to connect the bushing 209 to transmit the driving force of the first servo cylinder 208. The sleeve 207 is fixed on the second rotating shaft 206 and is used to fix the first servo cylinder 208. The first servo cylinder 208 is located in the inner cavity of the sleeve 207. The first servo cylinder 208 is a commonly used servo cylinder on the market. As the core power source of the power unit, it can accurately output linear driving force and control the rotation angle and speed of the swing arms 203. The bushing 209 is rotatably mounted on the connecting shaft 204 via a bearing to compensate for the angular deviation when the first servo cylinder 208 moves, thus avoiding motion interference. The output end of the first servo cylinder 208 is fixedly connected to the bushing 209. The crossbeam 210 is fixed between the two sets of swing arms 203 to fix the limit unit 3, thereby realizing the linkage between the power unit and the limit unit, driving the rod 8 to rotate synchronously. The bracket 301 is fixedly connected to the crossbeam 210.

[0039] Main references Figure 1 , Figure 3 and Figure 4As shown, the power unit 2 has a base unit 1 at its bottom. The base unit 1 includes a base plate 101, a recess 102, a clearance groove 103, a mounting block 104, and a waist hole 105. The base plate 101 is fixed to the bottom of the first mounting plate 201 and the second mounting plate 205, serving as the bottom support foundation for the entire equipment and ensuring the overall stability of the equipment. The recess 102 is recessed downward along the middle of the base plate 101, providing sufficient space for the relative rotation of the first servo cylinder 208. The clearance groove 103 is formed at the ends of the base plate 101 and the recess 102, and corresponds to... The unloading end of the bracket 301 has a clearance groove 103 that provides sufficient clearance space for the vertical rod 8, avoiding interference between the vertical rod 8 and the base plate 101, ensuring that the rod 8 can be smoothly lowered into the preset pit, and avoiding structural interference that affects construction; the mounting blocks 104 are divided into multiple groups and fixed to the side wall of the base plate 101 for connecting the carrier assembly 9 to fix the equipment and the carrier; the waist holes 105 are opened on each group of mounting blocks 104 to adapt to the connectors 902 of different specifications, which facilitates the installation and debugging of the equipment and the carrier assembly 9 and improves adaptability.

[0040] Additionally, see Figure 11 As shown, this communication line pole erecting machine is mounted on carrier assembly 9. Carrier assembly 9 includes a vehicle body 901 and a connector 902. The vehicle body 901 is a general-purpose transport vehicle used for transporting poles 8 in the prior art. A suitable carrier platform can be selected according to the specifications and model of the pole 8 to serve as the transport carrier between the equipment and the pole 8, enabling mobile construction without the need for additional transport equipment. The connector 902 is located below the mounting block 104. Existing locking bolts pass through and are threaded into the waist hole 105 and the connector 902, achieving a fixed assembly between the communication line pole erecting machine and the vehicle body 901. Specifically, the connector 902 consists of a supporting steel column and locking bolts, used to connect and assemble the entire equipment on the vehicle body 901, ensuring a firm connection between the equipment and the vehicle body 901 during transport and pole erection, preventing shaking. The vehicle body 901 provides a transport carrier and the foundation height required for the erection of pole 8. The pole 8 can be transported and positioned and erected without additional hoisting equipment, reducing the difficulty of construction in the field and under conditions without hoisting.

[0041] The working principle of a pole erecting machine for communication lines in this embodiment is as follows: First, the first servo cylinder 208 is activated and retracts, its output driving the bushing 209 and connecting shaft 204 to move synchronously, thereby driving the swing arm 203 to rotate counterclockwise around the first rotating shaft 202. During this rotation, because the first servo cylinder 208 forms a rotational engagement with the second mounting plate 205 through the second rotating shaft 206, it can adaptively rotate relative to the second rotating shaft 206 while driving the swing arm 203 to rotate, thereby compensating for motion interference and ensuring that the swing arm 203 rotates smoothly around the first rotating shaft 202. When the swing arm 203 rotates counterclockwise to 90°, the rod 8 completes the attitude conversion from a horizontal state to a vertical state. At this time, the rod 8 is already in the preset vertical attitude, requiring no additional correction, achieving verticality upon standing.

[0042] The bottom of the rod 8 is supported by the base plate 307, and the side wall is limited by the area formed by the engagement of the first arc plate 303 and the third arc plate 306, the second arc plate 305 and the fourth arc plate 308, so that the rod 8 maintains a vertical posture and provides guidance and constraint for subsequent vertical lowering.

[0043] When releasing rod 8, align the bottom of rod 8 with the preset pit position so that rod 8 can be lowered to the accurate position, ensuring the accurate placement of rod 8 and reducing the workload of subsequent correction. The output end of the second servo electric cylinder 401 retracts in a controlled manner, driving the drive rod 402, U-shaped seat 403, and pin 404 to move synchronously towards the bracket 301. Among them, pin 404 moves along the inner cavity of slide groove 702, temporarily not driving side plate 701. At this time, the second loosening unit 6 is still in the locked state, ensuring that the side wall of rod 8 is effectively limited. The movement of drive rod 402 causes the first slide bar 506 on the first rack 507 to move along the first groove plate 505, driving the first gear 503 meshing with the first rack 507 to rotate, thereby driving the third rotating shaft 502, the first connecting arm 504, the third arc plate 306, and the bottom plate 307 to rotate synchronously, causing the bottom plate 307 to rotate and release the support of the bottom of rod 8. During this process, the first arc plate 303 and the third arc plate 306, the second arc plate 305 and the fourth arc plate 308 continuously guide and limit the lowering of the rod 8, and the rod 8 falls into the corresponding pit under its own weight.

[0044] As the output end of the second servo electric cylinder 401 continues to retract, it drives the drive rod 402 to move continuously until the pin 404 moves to the end of the slide groove 702 and drives the side plate 701 to move synchronously towards the bracket 301. This causes the second slide bar 606 on the second rack 607 to move along the second groove plate 605, driving the second gear 603 meshing with the side wall of the second rack 607 to rotate. This enables the rotation of the fourth rotating shaft 602, the second connecting arm 604, and the fourth arc plate 308 to open, thus releasing the upper limit guide of the rod 8. At this time, the rod 8 has completed temporary support, and releasing the side wall limit will not affect its vertical posture.

[0045] The above structure enables the step-by-step action of first releasing the support at the bottom of the pole 8 and then releasing the guide limit on the side wall, so that the pole 8 is continuously subject to vertical guidance constraint throughout the erection process, improving the verticality control accuracy and the pole installation accuracy; at the same time, it eliminates the need for close-range manual correction, avoids the safety hazards of manual assistance, effectively improves construction quality and operational safety, and solves the problems of high labor intensity, high safety risk and low accuracy of traditional manual pole erection correction.

[0046] Compared with traditional pole erecting machines and triangular pole erecting machines, the advantages of this equipment at each stage are as follows: Lifting preparation stage: Connect and fix the rod 8 to the third arc plate 306 and the base plate 307 of the equipment. With the help of the equipment's own guide constraint structure, the rod 8 is kept vertical before lifting, without the need for additional vertical adjustment. Compared with the traditional lifting method that requires a dedicated person to use instruments to calibrate the verticality, which takes 15-20 minutes, this method can directly save 15-20 minutes of adjustment time and reduce the number of operators required.

[0047] During the pole lowering phase: The drive unit 4 is activated, and its output driving force first triggers the action of the first loosening unit 5, which drives the third arc plate 306 and the bottom support plate 307 to open synchronously, releasing the support constraint on the bottom of the pole 8. The pole 8 is lowered smoothly by its own weight, without the need for additional auxiliary hoisting equipment. Compared with traditional hoisting, which requires a crane to assist in the entire lowering process and takes 25-30 minutes per pole, this equipment only takes 8-10 minutes to lower a single pole, saving 17-22 minutes per pole and improving construction efficiency by more than 60%. There is no need to rent a crane, which effectively reduces equipment rental costs, and it is also suitable for construction scenarios without hoisting conditions.

[0048] Temporary fixing stage: After the pole 8 is lowered into the pre-set pole pit, it is fixed by a quick temporary support method such as wedge fixing or simple top support. The entire fixing process takes no more than 5 minutes. Compared with the traditional temporary support that requires the construction of a temporary support frame, which takes 10-15 minutes, each pole can save 5-10 minutes. At the same time, it reduces the investment of one set of temporary support equipment and reduces the temporary support cost of a single pole.

[0049] Equipment detachment stage: After the rod 8 is temporarily fixed and stabilized, the drive unit 4 continues to output power. In conjunction with the timing control of the step control unit 7, the second loosening unit 6 is triggered to open, driving the fourth arc plate 308 to release the limit on the side wall of the rod 8, and completing the complete detachment of the equipment from the rod 8. The entire detachment process takes no more than 2 minutes. Compared with the traditional equipment detachment which requires manual disassembly of the fixing parts and takes 8-10 minutes, it can save 6-8 minutes. It eliminates the need for manual disassembly, reduces labor intensity, and speeds up the equipment removal, saving time for the construction of the next work station.

[0050] In summary, using this equipment, the total time for the entire process of hoisting, lowering, temporarily fixing, and detaching a single communication pole can be controlled within 20-25 minutes. Compared to the traditional construction method, which takes 58-75 minutes, this saves 38-50 minutes per pole, increasing construction efficiency by over 65%. Furthermore, it eliminates the need for additional cranes, verticality calibration instruments, and other equipment, saving on equipment rental costs. It also reduces the number of operators by 2-3, further lowering labor costs. Overall construction costs can be reduced by 40%-50%, comprehensively improving construction efficiency, accuracy, and safety while lowering costs. It is suitable for various communication pole erection designs and conditions.

[0051] Example 2 See Figures 12 to 13 As shown in the two attached figures, these diagrams illustrate the structure of the pole 8 when it is pushed and flipped to a vertical position by the power unit 2. At this point, the entire device is in the transition phase where the pole has been erected and is ready to be lowered for installation. In this working state, the base plate 307 remains in its initial supporting position and has not yet disengaged from its contact with the bottom of the pole 8. It continues to provide stable support for the pole 8, ensuring that it maintains its vertical posture and does not tilt or fall due to loss of bottom support. This prepares the pole 8 for subsequent alignment with the pit and smooth lowering, ensuring the structural stability during the transition phase.

[0052] Example 3 See Figure 14 As shown in the attached diagram, the structural state of the third arc-shaped plate 306 and the fourth arc-shaped plate 308 when they are rotated to the preset opening angle is illustrated. At this point, the equipment has completed all guiding, limiting, and supporting functions for the rod 8. In this state, the third arc-shaped plate 306 and the base plate 307 have been fully rotated to the opening position, completely disengaging from contact with the bottom end of the rod 8 and releasing the supporting constraint on the bottom end of the rod 8. At the same time, the fourth arc-shaped plate 308 has also been rotated to the preset opening angle, completely disengaging from contact with the side wall of the rod 8 and releasing the guiding and limiting constraint on the side wall of the rod 8.

[0053] In other words, at this point, pole 8 has completely lost the supporting and guiding function of the limiting unit 3 at its bottom and its sidewalls, thus achieving complete separation of the equipment from pole 8. Pole 8 is now vertically stable thanks to temporary support or subsequent fixing measures, and the equipment no longer needs to constrain pole 8, allowing for smooth removal from the site and entry into the next pole erection work position, effectively improving construction efficiency.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
