Abstract

This invention discloses an auxiliary installation and hoisting device and method for automatic liquid balancing of a lifting pole, relating to the field of hoisting technology. It includes a main lifting pole suspended in the middle of a steel tower, composed of multiple pole sections. The top of the main lifting pole has a cap and is connected to the upper part of the tower or external traction equipment via a guy wire system. The bottom of the main lifting pole has a base and is supported by a support system to the lower part of the tower, thus keeping the main lifting pole in a suspended state in the middle of the tower during construction.

Description

Technical Field

[0001] This invention relates to the field of hoisting technology, specifically to an auxiliary installation hoisting device and method with automatic liquid balancing on a boom. Background Technology

[0002] Pole-mounted tower erection is an important method in the construction of overhead transmission lines. It uses a pole-mounted system to support and fix the towers, ensuring their stability and safety during construction. Construction methods for pole-mounted tower erection include internally suspended pole-mounted disassembly and erection, ground-mounted rocker arm pole-mounted disassembly and erection, and tower crane erection. These methods are suitable for towers of different heights and weights and can be carried out under various terrain conditions.

[0003] The construction process of gantry tower assembly involves multiple steps, including the assembly, hoisting, installation, and dismantling of the gantry. During construction, appropriate construction methods must be adopted to disassemble and hoist the tower according to factors such as the structural dimensions and component weights, ultimately completing the tower's erection.

[0004] Publication No. CN218642329U discloses a pole assembly device, which includes a base, a pole body, a mast, a rocker arm, and a hoisting mechanism. The pole body comprises multiple standard pole sections connected in sequence. Flanges are fixed at both ends of each standard pole section along its length. Several connecting plates are arranged between adjacent standard pole sections. One side of each connecting plate has a mounting groove for accommodating two adjacent flanges, and the sides of adjacent flanges facing away from each other abut against the sidewall of the mounting groove. The connecting plate also has a locking assembly for locking the connecting plate to the flange. This device effectively reduces the assembly time of the pole body.

[0005] During the hoisting process of a suspended gantry, it is necessary to adjust the temporary guy lines, wire rope attachment points and tension, gantry counterweight and windproof rope tension in real time to ensure that the horizontal and inclined members are accurately positioned and maintain overall stability. During the hoisting process, the gantry needs to be tilted towards the hoisting side, but it needs to be kept within a reasonable tilt angle range to ensure that the force on the gantry is more reasonable. However, for a gantry that lacks balance, changing the tilt angle will increase the force on one side, resulting in a worse balance of the gantry. Summary of the Invention

[0006] One of the objectives of this invention is to provide an auxiliary installation and hoisting device and method for automatic liquid balancing of a gantry, which can automatically balance the hoisting load of the gantry in real time, reduce stress concentration at the joints and hinges, and improve the hoisting response speed and accuracy.

[0007] To achieve the above objectives, the first aspect of this application provides an auxiliary installation and hoisting device with automatic liquid balancing for pole mounting, comprising:

[0008] The main pole is composed of multiple pole sections spliced ​​together in sequence. The top and bottom of the main pole are respectively equipped with a pole cap and a pole base.

[0009] The guy wire system and the support system are provided. One end of the guy wire system is connected to the pole cap and the other end extends outward. One end of the support system is connected to the pole base and the other end is fixed to the lower part of the tower. The guy wire system and the support system work together to make the main pole suspend in the tower.

[0010] The side support rod is hinged to a predetermined connection position on the outside of the main support rod and can swing up and down around the hinge axis;

[0011] A counterweight system is installed between the side support rod and the main support rod, so that the side support rod can have both hoisting and counterweight states;

[0012] The counterweight system includes a water storage tank located at the main mast, a counterweight water tank located at the side mast, and a pipeline system that fluidly connects the water storage tank and the counterweight water tank. The pipeline system allows the fluid volume in the water storage tank and the counterweight water tank to be adjusted separately or simultaneously when the side mast is in the hoisting state and / or in the counterweight state, so as to change the center of gravity position of the side mast and achieve the balance of the main mast.

[0013] Furthermore, the piping system includes: connecting hoses, a liquid pump, an electrically controlled valve, a flow meter, and a check valve, wherein the liquid pump, the electrically controlled valve, the flow meter, and the check valve are located on the side of the piping system near the main support rod;

[0014] The connecting hose includes a first hose and a second hose. One end of the first hose is in fluid communication with the counterweight water tank, and the other end is connected to the outlet of the liquid pump. One end of the second hose is connected to the inlet of the liquid pump, and the other end is in fluid communication with the water storage tank.

[0015] The electrically controlled valve, flow meter, and check valve are sequentially installed at the second flexible hose.

[0016] Furthermore, an inclinometer is installed at one end of the side support rod that connects to the main support rod to detect the tilt angle of the side support rod in real time during the hoisting process.

[0017] The side support rod extends outward at one end and is equipped with a hook that hangs vertically to the ground. The hook can be raised and lowered vertically via a lifting assembly to adjust its height.

[0018] Furthermore, the counterweight water tank is located on the side of the side arm extending outward, and a liquid level sensor is installed inside the counterweight water tank. The side arms arranged symmetrically at 180° form the same balance system.

[0019] When one side support rod is in the hoisting state, the pipeline system transports the liquid in the water storage tank to the counterweight water tank of the other side support rod, so that the other side support rod is in the counterweight state.

[0020] When both side booms are in the hoisting state and the hoisting weights on both sides are different, the pipeline system causes the counterweight water tank on the lighter side boom to receive the corresponding amount of liquid and be in the counterweight state.

[0021] Furthermore, the counterweight water tank is located in the middle of the side support rod, and the counterweight water tank is equipped with at least one partition to divide the internal space of the water tank into multiple interconnected water compartments.

[0022] Each water tank is connected by a connecting pipe located outside the counterweight water tank. Each water tank is equipped with a squeezing assembly, which consists of a push plate and a hydraulic rod. The hydraulic rod drives the push plate to move controllably along the extension and retraction direction of the hydraulic rod to adjust the volume of the water tank.

[0023] By controlling the actions of the squeezing components in each water tank separately, the counterweight status of the counterweight water tank can be adjusted in zones.

[0024] Furthermore, the partition is internally configured with a sliding insert plate relative to the partition. One end of the insert plate is connected to the partition via an electromagnetic component, which is used to drive the insert plate to slide along a set direction.

[0025] When the insert plate retracts inside the partition, the water tanks maintain fluid communication through the connecting pipes. When the insert plate is pushed outward to the outside of the partition, the insert plate and the partition form a sealing fit, thereby achieving the separation of adjacent water tanks.

[0026] Solenoid valves are installed between the connecting pipes to control the opening and closing of the fluid between the water tanks in coordination with the insert plate.

[0027] Furthermore, the main support rod is provided with an installation section in the middle, the side support rod is hinged to the outside of the installation section, and positioning plates are provided at the connection points between the upper and lower sides of the installation section and the adjacent rod sections, respectively;

[0028] A support structure is provided between the positioning disk and the rod section, and the support structure is used to control the positioning disk to be inserted into or withdrawn from the installation section radially.

[0029] When the positioning plate is inserted into the mounting section, the positioning plate engages with the mounting section, thereby locking and fixing the mounting section relative to the corresponding rod section.

[0030] When the positioning plate exits the mounting section, the mounting section rotates freely relative to the hinge with the rod section to change the lateral angle of the side arm.

[0031] Furthermore, the mounting section is provided with chucks on both the upper and lower sides. The chucks are embedded in and cooperate with the adjacent rod sections. The mounting section is provided with pull rods on both the upper and lower sides. The pull rods are provided with retaining rings at the outer ends of the pull rods. The retaining rings are respectively installed on the outer sides of the corresponding rod sections on the upper and lower sides of the mounting section and can rotate freely relative to the rod sections.

[0032] Both the upper and lower sides of the mounting section are equipped with drive components, which are used to drive the mounting section to rotate relative to the corresponding rod section.

[0033] Furthermore, the drive assembly drives the mounting section to rotate within an angle range of 0°-135°. When the mounting section rotates to 0°, 45°, 90° and 135°, the positioning disk can be inserted into the mounting section.

[0034] The drive assembly includes a drive motor installed inside the rod section, a reducer installed outside the drive motor, and the drive motor shaft connected to the input end of the reducer, and the mounting section connected to the output end of the reducer.

[0035] A second aspect of this application provides a lifting method with automatic liquid balancing for a lifting pole, comprising the following steps:

[0036] The main mast is suspended in the middle of the tower to a predetermined position by a guy wire system and a support system. The liquid in the water storage tank is distributed to the two side counterweight tanks according to the design torque distribution and the initial counterweight strategy to achieve static balance.

[0037] Set a period to collect data from the counterweight system and calculate the torque difference and tilt deviation between the left and right side poles;

[0038] The counterweight adjustment plan is determined and executed according to priority. The corresponding electronic control valve is opened and the liquid pump is driven to transport the liquid in the storage tank to the target counterweight tank, or the excess liquid is pumped back to the storage tank.

[0039] Based on the feedback from the flow meter and the data from the inclinometer, the pump speed and the opening of the electronically controlled valve are controlled in segments to control the swing rate of the side lever and the rate of change of liquid volume.

[0040] After hoisting is completed, the load is smoothly transferred to the permanent structure using a step-by-step deceleration and step-by-step recovery strategy for the counterweight fluid. At the same time, the counterweight fluid is recovered into the water tank and the positioning lock is released. Finally, the pump valve is switched to standby mode and maintenance and operation data are archived.

[0041] Through the above technical solution, the present invention has the following beneficial effects:

[0042] 1. During the hoisting process, the side booms are automatically balanced by adjusting the liquid inside the water storage tank and the counterweight water tank, thereby improving the stability of the main boom during hoisting. The side booms can also be adjusted according to the hoisting position, allowing them to be hoisted at multiple positions, thus reducing the number of side booms required.

[0043] 2. A counterweight water tank is arranged at the end of the side support rod to obtain a longer torque arm. The required counterweight mass is small to achieve balance. The system has a sensitive response and is suitable for scenarios that require rapid adjustment. The pipeline layout is relatively simple and easy to maintain. In addition, calcium chloride solution is placed in the counterweight water tank to reduce the volume of the counterweight water tank.

[0044] 3. The counterweight tank is set as a long tank to increase the overall counterweight capacity and adjustable range. The zoned design allows for micro-shifting and local compensation of the counterweight's center of gravity by changing the volume of a local compartment or closing the connecting area. It is suitable for long-term or heavy-load operations that require large and gradual counterweights. It can adjust the local center of gravity by changing the volume of a certain compartment without changing the total liquid volume.

[0045] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0071] The following describes several embodiments of the present invention with reference to the accompanying drawings. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential. And features of different embodiments may be interchanged if feasible.

[0072] Unless otherwise defined, all terms used herein (including technical and scientific terms) have their ordinary meanings, which are understandable to those skilled in the art. Furthermore, the definitions of the foregoing terms in commonly used dictionaries should be interpreted in the context of this specification as having the meaning consistent with the relevant field of this invention. Unless specifically defined, these terms will not be construed as having idealized or overly formal meanings.

[0073] The following explains the relationships and terms used in this application:

[0074] Parallelism: The parallelism defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism. It allows for situations where the parallelism is not absolute due to factors such as assembly tolerance, design tolerance, and structural flatness. It also allows for errors within a small angular range, such as within 10 degrees of assembly error. These can all be considered as parallel relationships.

[0075] Perpendicularity: The perpendicularity defined in this application is not limited to an absolute perpendicular intersection (with an included angle of 90 degrees). It is permissible for non-absolute perpendicular intersections caused by factors such as assembly tolerances, design tolerances, and structural flatness. It is permissible for errors within a small angular range, such as an assembly error range of 80 to 100 degrees, which can all be understood as a perpendicular relationship.

[0076] Ground: The ground as defined in this application is not limited to a specific material or region, but simply refers to a platform on which this application is supported, and allows for stacking, tilting, and variations in flatness. For example, cement floors, tile floors, work platforms, etc., can all be interpreted as ground.

[0077] The above explanation does not fully encompass the relationship definition given in this application, but only represents a part of it.

[0078] Example 1, see Figure 1-2As shown, Embodiment 1 of the present invention provides an auxiliary installation and hoisting device for automatic liquid balancing of a gantry crane. It includes a main gantry crane 1 suspended in the middle of the tower. The main gantry crane 1 is composed of multiple sections 11 spliced ​​together. The top is provided with a gantry crane cap 13 and is connected to the upper part of the tower body or to external traction equipment through a guy wire system 2. The bottom is provided with a gantry crane base 14 and is supported by a support system 3 to the lower part of the tower body, so that the main gantry crane 1 is in the middle of the tower body and in a suspended state during construction. A counterweight system 5 is provided between the side gantry crane 4 and the main gantry crane 1, so that the side gantry crane 4 can have both hoisting and counterweight states.

[0079] The main boom 1 is hinged to the outside to form symmetrically arranged side booms 4. The outer end of the side boom 4 is equipped with a hook 6, and its vertical height is controlled by a lifting assembly 7. The lifting assembly 7 can be installed at the side boom 4, and the height of the hook 6 can be controlled remotely. Alternatively, the lifting assembly 7 can be installed on the ground, and pulleys can be configured inside the side boom 4 to control the height change of the hook 6.

[0080] A water storage tank 51 is installed near the middle of the outer side of the main support pole 1, and a counterweight water tank 52 is installed on the side support pole 4. The water storage tank 51 and the counterweight water tank 52 are connected by a pipeline system 53.

[0081] The counterweight water tank 52 is located on the side of the side arm 4 extending outward. The counterweight water tank 52 is equipped with a liquid level sensor 55. The side arms 4, which are arranged symmetrically at 180°, form the same balance system.

[0082] When one side boom 4 is in the hoisting state, the pipeline system 53 transports the liquid in the water storage tank 51 to the counterweight water tank 52 of the other side boom 4, so that the other side boom 4 is in the counterweight state. At this time, the weight of the side boom 4 in the hoisting state is reduced, and the weight of the side boom 4 in the counterweight state is increased, so as to maintain the stability of the main boom 1.

[0083] When both side booms 4 are in the hoisting state and the hoisting weights on both sides are different, the pipeline system 53 causes the counterweight water tank 52 on the side boom 4 with the lighter weight to receive the corresponding amount of liquid and be in the counterweight state. When different weights are hoisted on both sides, the medium inside the counterweight water tank 52 on both sides is adjusted according to the weight difference between the hoisting weights of the two side booms 4, changing the amount of medium and causing the weight of the counterweight water tank 52 on both sides to change in order to adapt to the change in hoisting weight on both sides.

[0084] For example, in this application, the two side support poles 4 are divided into a left support pole and a right support pole. When one of the side support poles 4 is used for hoisting: the left support pole is in the hoisting state and the right support pole is in the counterweight state; the right support pole is in the hoisting state and the left support pole is in the counterweight state.

[0085] When both side booms 4 are being hoisted, additional counterweights are added based on the hoisting weight of the two side booms 4: if the hoisting weight of the left boom is greater than that of the right boom, then additional counterweights are added to the right boom; if the hoisting weight of the right boom is greater than that of the left boom, then additional counterweights are added to the left boom.

[0086] This application does not limit the liquid used for counterweighting inside the water storage tank 51 and the counterweight tank 52, as long as the counterweight adjustment of the side support rod 4 can be achieved through fluid communication. The preferred liquid is water or calcium chloride solution.

[0087] Among them, calcium chloride solution has the advantages of higher density and lower freezing point compared to water.

[0088] For example, a 20% calcium chloride solution has a freezing point of approximately -18°C. A 30% calcium chloride solution can drop to below -48°C. For high-altitude mountainous areas, and especially for low nighttime and winter temperatures, preparing an appropriately concentrated calcium chloride solution ensures that the counterweight liquid remains liquid at extreme temperatures, thus guaranteeing the continuity and safety of construction.

[0089] Increase the counterweight density and decrease the volume.

[0090] Calcium chloride solution has a higher density than water (at room temperature, the density of a 20% concentration solution is about 1.17 g / cm³, and that of a 30% solution is about 1.29 g / cm³).

[0091] If the same counterweight mass is required, a smaller volume of solution can be used, so that the water storage tank 51 and the counterweight tank 52 can be designed to be smaller and lighter, reducing the burden of transportation and installation.

[0092] For the existing fixed-size water storage tank 51 and counterweight water tank 52, a heavier counterweight can be installed, which increases the lifting capacity margin of the boom.

[0093] Inhibits the growth of bacteria and algae.

[0094] Water left to stand for a long time, especially in summer, is prone to the growth of algae and bacteria, producing odors and sediment.

[0095] Calcium chloride solution creates a hypertonic environment that effectively inhibits the growth of microorganisms. For projects requiring long-term construction, it helps keep the counterweight system clean and reduces maintenance.

[0096] Lower vapor pressure (secondary benefit).

[0097] At the same temperature, the vapor pressure of calcium chloride solution is lower than that of pure water, meaning it evaporates more slowly. In areas with high altitudes, strong winds, and intense sunlight, this reduces water loss through evaporation and decreases the frequency of liquid replenishment.

[0098] Example 2, see Figure 3-6 As shown, Embodiment 2 of this application provides an auxiliary installation and hoisting device with automatic liquid balancing for a lifting pole. This embodiment is implemented based on Embodiment 1. The hoisting device includes basic units such as: main lifting pole 1, side lifting pole 4, water storage tank 51, counterweight water tank 52, and pipeline system 53.

[0099] Compared with Example 1, the difference in this example is:

[0100] The piping system 53 consists of a connecting hose 531, a liquid pump 532, an electrically controlled valve 533, a flow meter 534, and a check valve 535. The liquid pump 532, the electrically controlled valve 533, the flow meter 534, and the check valve 535 are centrally arranged on the side near the main support 1 and are fixed by brackets or partially directly installed on the water storage tank 51. Installing some piping components on the side near the main support 1 can reduce the weight at the side support 4.

[0101] The counterweight water tank 52 is located at one end of the side support rod 4 extending outward. The water tank is equipped with a liquid level sensor 55 and a connecting hose 531 for conveying between the water storage tank 51 and the counterweight water tank 52. The liquid medium inside the water storage tank 51 enters the pump inlet of the liquid pump 532 through the second hose 531b; the outlet of the liquid pump 532 is conveyed to the counterweight water tank 52 through the first hose 531a.

[0102] A check valve 535 is placed between the water storage tank 51 and the liquid pump 532 to prevent backflow. An electrically controlled valve 533 and a flow meter 534 are located between the liquid pump 532 and the water storage tank 51 and are arranged close to the main support rod 1.

[0103] By arranging the counterweight water tank 52 at the end of the side support rod 4 to obtain a longer torque arm, the required counterweight mass can achieve balance. The system has a sensitive response and is suitable for scenarios that require rapid adjustment. The pipeline layout is relatively simple and easy to maintain.

[0104] The data from the liquid level sensor 55, the flow meter 534, and the liquid pump 532 work together to accurately determine the weight balance configuration of the counterweight tank 52 and ensure a balanced state.

[0105] Example 3, see Figure 7-14 As shown, Embodiment 3 of this application provides an auxiliary installation and hoisting device with automatic liquid balancing for a lifting pole. This embodiment is implemented based on Embodiment 1. The hoisting device includes basic units such as: main lifting pole 1, side lifting pole 4, water storage tank 51, counterweight water tank 52, and pipeline system 53.

[0106] Compared with Example 1, the difference in this example is:

[0107] The counterweight water tank 52 is located in the middle of the side support rod 4 and has a relatively long length. The counterweight water tank 52 has at least one partition 521 inside to divide it into multiple water compartments, and each water compartment is equipped with a connecting pipe 527 on its outside.

[0108] Each water tank is equipped with an extrusion assembly 522 for changing the tank volume. The extrusion assembly 522 includes a push plate 523 and a hydraulic rod 524. The fixed end of the hydraulic rod 524 is installed on the inner wall of the counterweight water tank 52, and the telescopic end of the hydraulic rod 524 is installed on one side of the push plate 523. The telescopic adjustment of the hydraulic rod 524 adjusts the position of the push plate 523 in the water tank to change the counterweight volume of the water tank.

[0109] The counterweight water tank 52 is equipped with a connecting pipe 527 on the outside to connect multiple water tanks. When the hydraulic rod 524 squeezes the water tank through the push plate 523, the liquid inside the water tank can enter other water tanks through the connecting pipe 527.

[0110] In addition, the inner wall of the water tank is set in a stepped shape, that is, there is a gap between the upper inner wall of the water tank near the hydraulic rod 524 and the push plate 523, and the lower inner wall of the water tank is in contact with the outer wall of the push plate 523. When the push plate 523 moves to the lower side, the push plate 523 is in contact with the inner wall of the water tank, and the hydraulic rod 524 pushes the push plate 523, so that the liquid in the water tank enters other water tanks through the connecting pipe 527. When the push plate 523 moves to the upper side, there is a gap between the push plate 523 and the inner wall of the water tank, and the inside of the water tank is connected to the outside.

[0111] By setting the sidewalls of the water tanks in a stepped shape, the total volume of the counterweight tank when multiple water tanks are in a sealed state can be determined. When the push plate is in the upper part of the water tank, the push plate does not fit against the inner wall of the water tank. When the push plate is in the lower part of the water tank, the push plate fits against the inner wall of the water tank, sealing the water tank.

[0112] For example, the water tank is divided into a first water tank, a second water tank, and a third water tank from one side to the other. Since the water tanks are in a connected state, when the push plate 523 in the first water tank is in the upper part of the water tank and is not in contact with the inner wall of the water tank, the push plates 523 in the second and third water tanks move to different positions in the lower part of the water tank, and then the push plate 523 in the first water tank is brought into contact with the inner wall of the water tank, that is, the total volume of the counterweight water tank 52 composed of the first water tank, the second water tank, and the third water tank is changed.

[0113] In a further embodiment of this example, a slidable insert plate 525 is provided inside the partition plate 521. One end of the insert plate 525 is connected to an electromagnetic component 526 to realize the extension and retraction of the insert plate 525, so that the water tank can switch between connection and separation.

[0114] A solenoid valve 528 is installed between the connecting pipes 527 and the slide plate 525 to work together.

[0115] When both the gate plate 525 and the solenoid valve 528 are in the isolated state, the water tanks are independent of each other.

[0116] The long container increases the overall counterweight capacity and adjustable range. The zoned design allows for slight shifts in the center of gravity and local compensation of the counterweight by changing the volume of local water tanks or closing connecting areas. It is suitable for long-term or heavy-load operations that require large and gradual counterweights.

[0117] The extrusion assembly 522 can adjust the local center of gravity by changing the volume of a certain compartment without changing the total liquid volume.

[0118] The combination of the slide gate 525 and the solenoid valve 528 enables rapid zone switching, which is beneficial for forming independent or combined water tank configurations to match different operating conditions.

[0119] Example 4, see Figure 15-19 As shown, Embodiment 4 of this application provides an auxiliary installation and hoisting device with automatic liquid balancing for a lifting pole. This embodiment is based on Embodiment 1 / Embodiment 2 / Embodiment 3. The hoisting device includes basic units such as: main lifting pole 1, side lifting pole 4, water storage tank 51, counterweight water tank 52, and pipeline system 53.

[0120] Compared with Embodiment 1 / Embodiment 2 / Embodiment 3, the difference in this embodiment is as follows:

[0121] A mounting section 12 is provided in the middle of the main support pole 1. The upper and lower sides of the mounting section 12 are respectively matched with the adjacent pole sections 11, and a positioning plate 15 is set at the connection of the pole sections 11. The positioning plate 15 can be controlled by the support structure 16 to be inserted into or removed from the mounting section 12 radially.

[0122] The bottom of the mounting section 12 is provided with a chuck 17 that is embedded inside the rod section 11. The upper and lower sides of the mounting section 12 are provided with pull rods 18. The outer end of the pull rod 18 is provided with a retaining ring 19, and the retaining ring 19 is sleeved on the adjacent rod section 11 so that it can rotate relative to the rod section 11.

[0123] By setting the installation section 12, the rotation angle of the side support rod 4 can be adjusted during use, allowing the side support rod 4 to swing to different angles. With two side support rods 4, hoisting can be achieved at eight angle positions, improving the convenience of hoisting and avoiding the need to set multiple side support rods 4 for multi-directional hoisting.

[0124] Both sides of the mounting section 12 are equipped with drive assemblies 110, which are used to drive the mounting section 12 to rotate within the range of 0°–135°. The drive assembly 110 consists of a drive motor 1101 and a reducer 1102. The drive motor 1101 is connected to the rod section 11, and the reducer 1102 is connected to the mounting section 12. When the drive assembly 110 is connected to the reducer and drives the mounting section 12 to rotate to the four corner positions of 0°, 45°, 90°, and 135° through the reducer 1102, the positioning plate 15 can be inserted and locked.

[0125] In addition, a gear set is provided between the reducer 1102 and the mounting section 12 for connecting the two for transmission. The gear set includes an internal gear fixed inside the chuck 17 and an external gear installed on the output section of the reducer. The internal gear and the external gear mesh and transmit power. The drive motor rotates and drives the external gear to rotate through the reducer, so that the internal gear and the mounting section 12 connected to it rotate.

[0126] The pull rod 18 located outside the mounting section 12 can transfer the tension of the side support rod 4 to the mounting section 11.

[0127] The mounting section 12, in conjunction with the positioning plate 15, enables rapid angle positioning and locking, facilitating the switching of lifting / counterweight states at different angles and providing a stable geometric baseline for closed-loop control of the liquid counterweight. Furthermore, since the pipeline is composed of connecting hoses 531, no damage to the pipeline will occur when the side support rod 4 and mounting section 12 rotate as a whole.

[0128] Example 5: This application provides a lifting method with automatic liquid balancing for a lifting pole, comprising the following steps:

[0129] The main mast 1 is suspended in the middle of the tower to a predetermined position by the guy wire system 2 and the support system 3. The liquid in the water storage tank 51 is distributed to the two side counterweight water tanks 52 according to the design torque distribution and the initial counterweight strategy to achieve near static balance.

[0130] Set a period to collect data from the counterweight system 5, and calculate the torque difference and tilt deviation of the left and right side support poles 4;

[0131] The counterweight adjustment plan is determined and executed according to priority. The corresponding electronic control valve 533 is opened and the liquid pump 532 is driven to transport the liquid in the water storage tank 51 to the target counterweight water tank 52, or the excess liquid is pumped back to the water storage tank 51.

[0132] Based on the feedback from the flow meter 534 and the data from the inclinometer 54, the pump speed and the opening of the solenoid valve 533 are controlled in segments to control the swing rate of the side lever 4 and the rate of change of liquid volume.

[0133] After hoisting is completed, the load is smoothly transferred to the permanent structure using a step-by-step deceleration and step-by-step recovery strategy for the counterweight liquid. At the same time, the counterweight liquid is recovered to the water storage tank 51 and the positioning lock is released. Finally, the pump valve is switched to standby mode and maintenance and operation data are archived.

[0134] Although the present invention has been disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the appended claims.
