[0030] Example 1 Reference Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides an adjustment mechanism suitable for high-altitude tower erection operations of high and low leg iron tower foundations in mountainous and hilly areas of Yunnan. Its core purpose is to achieve high-precision automatic leveling on uneven and soft / hard foundations, and to provide stable support for the hoisting poles used for iron towers.

[0031] like Figures 1 to 4 As shown, the adjustment mechanism includes a base 1, a self-balancing unit 2, and an extension 24. All components are made of high-strength steel to meet the load requirements of 5t to 40t tower hoisting operations and ensure the structural load-bearing stability.

[0032] The base 1 is an integral bearing foundation. The four corners of the upper side of the base 1 are respectively provided with through holes 223 that penetrate to the lower surface of the base. The inner diameter of the through hole 223 is adapted to the outer diameter of the connecting rod 222, so as to realize the rotational engagement between the connecting part 22 and the base 1, and provide a rotational foundation for subsequent adaptive ground undulation.

[0033] There are a total of 4 sets of self - balancing units 2, and their layout is adapted to the base 1. The 4 sets of self - balancing units 2 are radially distributed along the two diagonal directions of the base 1, and the center line of each set of self - balancing units 2 coincides with the corresponding diagonal of the base 1, that is, they are arranged at the four corners of the base 1 along the 45° diagonal direction. Full - direction leveling is achieved through the coordinated action of the four groups.

[0034] Each set of self - balancing units 2 includes a support arm 21, a connecting piece 22, and a hydraulic cylinder 23. The connecting piece 22, as the connection carrier between the self - balancing unit 2 and the base 1, includes a connecting seat 221 and a connecting rod 222. The cross - section of the connecting seat 221 is in the shape of a "匚", and a connecting rod 222 is fixedly connected to its inner side wall by a full - welding process. The axis of the connecting rod 222 is perpendicular to the opening direction of the "匚" shape of the connecting seat 221, and both ends of the connecting rod 222 extend out of both sides of the connecting seat 221. On the outer side wall of the connecting seat 221, that is, the side wall facing away from the "匚" - shaped opening, two groups of connecting plates 224 are fixedly connected by welding: the two groups of connecting plates 224 are respectively arranged close to the two side edges of the connecting seat 221, and are symmetrically distributed in a mirror image with the longitudinal center line of the connecting seat 221 as the symmetry axis. Coaxial assembly holes 225 are opened on both the upper and lower sides of each group of connecting plates 224. The lower - side assembly hole 225 is used for pivotally connecting with the support arm 21, and the upper - side assembly hole 225 is used for installing a hinge to connect the hydraulic cylinder 23. Both ends of the connecting rod 222 are respectively inserted into the through - holes 223 at the corresponding corners of the base 1, and the connecting rod 222 and the through - hole 223 are in clearance fit, enabling the connecting piece 22 to rotate around the axis of the through - hole 223, thereby adapting to the inclination of the base 1 caused by local undulations of the foundation.

[0035] The support arm 21 is a long - strip steel structure member. One end of it is pivotally connected to the two groups of connecting plates 224 of the connecting piece 22 through a rotating shaft. Both ends of the rotating shaft are respectively inserted into the lower - side assembly holes 225 of the two groups of connecting plates 224, and the rotating shaft and the assembly hole 225 are in clearance fit; to prevent axial movement of the rotating shaft, the parts of both ends of the rotating shaft extending out of the assembly hole 225 are locked by nuts, and flat washers and spring washers are sequentially arranged between the nuts and the connecting plates 224 to prevent loosening. The support arm 21 can rotate around the axis of the rotating shaft to adjust the support angle.

[0036] The hydraulic cylinder 23, as the power component for driving the support arm 21 to rotate, is respectively rotationally connected to the connecting piece 22 and the support arm 21 at both ends. The bottom of the cylinder barrel of the hydraulic cylinder 23 is connected to the two groups of connecting plates 224 through a hinge. Both ends of the hinge are respectively fixed to the upper - side assembly holes 225 of the two groups of connecting plates 224, enabling the cylinder barrel of the hydraulic cylinder 23 to rotate around the axis of the hinge, and the axis of this hinge is parallel to the axis of the rotating shaft used for pivotally connecting the support arm 21; at this time, the cylinder barrel of the hydraulic cylinder 23 is located directly above the support arm 21, forming an upper - side drive for the support arm 21. The piston rod end of the hydraulic cylinder 23 is hinged to the outer wall of the middle area of ​​the support arm 21 through a bearing: the support arm 21 is provided with an outwardly protruding hinge ear plate at the corresponding position, the bearing is embedded in the shaft hole of the ear plate, and the piston rod end is fixed to the inner ring of the bearing through a shaft pin. In use, the extension and retraction of the piston rod of the hydraulic cylinder 23 can drive the support arm 21 to rotate around the pivot axis between it and the connecting plate 224, thereby adjusting the tilt angle of the support arm 21. In conjunction with the coordinated action of the four self-balancing units 2, the horizontal correction of the base 1 can be achieved.

[0037] The extension 24 is located at the end of the support arm 21 away from the connector 22, and is used to further expand the support radius of the adjustment mechanism and adapt to more complex terrain. The extension 24 includes an extension sleeve 241, an extension arm 243, and a positioning bolt 246. Among them, the extension sleeve 241 is a rectangular sleeve structure with one end open. Its outer wall is fixed to the inner cavity of the support arm 21 away from the connector 22 by welding, and the axis of the extension sleeve 241 is consistent with the length direction of the support arm 21. A rectangular movable groove 242 is provided on the side surface of the extension sleeve 241 away from the connecting seat 221. The cross-sectional dimensions of the movable groove 242 are adapted to the cross-sectional dimensions of the extension arm 243. The extension arm 243 can move back and forth along the length direction of the movable groove 242 to realize the adjustment of the support radius. Several sets of adjustment holes 244 are equally spaced on both sides of the extension arm 243 along its length direction. Positioning holes 245 that connect to the movable groove 242 are correspondingly opened on both sides of the extension sleeve 241. When the extension arm 243 moves along the movable groove 242 to the preset support radius position, the extension arm 243 is finely adjusted so that the positioning hole 245 is aligned with the closest set of adjustment holes 244 on the extension arm 243. The positioning bolts 246 are then inserted into the positioning hole 245 and the adjustment hole 244 in sequence and locked with nuts, which can limit the movement of the extension arm 243 and ensure support stability.

[0038] In addition, the side of the extension arm 243 away from the extension sleeve 241 is rotatably connected to a balance foot 247 via a pivot. The bottom of the balance foot 247 is provided with a square foot plate adapted to uneven terrain. The lower surface of the foot plate can be provided with anti-slip texture. The balance foot 247 can rotate relative to the extension arm 243 around the pivot. When there are local protrusions, depressions or slight slopes in the foundation, the balance foot 247 can adaptively rotate to make the foot plate completely fit the foundation surface, further improving the support stability of the adjustment mechanism and avoiding tilting caused by uneven force at a single point.

[0039] Example 2 Reference Figures 5 to 6This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a self-balancing base for a double rocker arm, including a detection unit 3, a controller 31, and a dual-axis tilt sensor 32. The controller 31 is electrically connected to the dual-axis tilt sensor 32, and the dual-axis tilt sensor 32 is fixedly installed on the outer wall of the cylinder body of the hydraulic cylinder 23.

[0040] The detection unit 3 is the control center of the adjustment mechanism's "high-precision automatic leveling". It is used to monitor the foundation tilt status in real time, provide feedback on leveling data, and receive operation commands to drive the self-balancing unit 2 to operate.

[0041] like Figure 5 As shown, the detection unit 3 includes a controller 31, a sensor assembly, and a human-machine interface, which interact with each other via wires. Among them, the controller 31 is an industrial-grade programmable logic controller 31, which has the characteristics of resisting high and low temperatures and resisting electromagnetic interference, and is suitable for the harsh environment of outdoor tower erection operations in the high mountains and hilly areas of Yunnan. The controller 31 is fixed to the upper center area of ​​the base 1 through a waterproof mounting box. The signal input terminal of the controller 31 is connected to the dual-axis tilt sensor 32 via a cable to receive tilt angle and attitude data; the signal output terminal is connected to the solenoid valves of the hydraulic cylinders 23 of the four self-balancing units 2 via a relay module to control the extension and retraction of the hydraulic cylinders 23. At the same time, the controller 31 communicates bidirectionally with the human-machine interface via Ethernet to realize data uploading and command reception. The controller 31 has a built-in leveling control algorithm, which can automatically calculate the target extension and retraction of the four hydraulic cylinders 23 based on the levelness data of the base 1 fed back by the dual-axis tilt sensor 32, and drive the hydraulic cylinders 23 to work together.

[0042] The system and equipment operation are interlocked. When deployed in a non-horizontal state, the base 1 is first disassembled and assembled at the construction site. The base 1 is then fixed to the ground by a string line. After the system is started, the dual-axis tilt sensor 32 monitors the tilt angle of the base in the X and Y axes in real time. The core controller 31 receives the signal from the dual-axis tilt sensor 32, calculates the required extension and retraction of each outrigger according to the preset leveling algorithm, and drives the hydraulic cylinder 23 to extend and retract the support arm 21 until the base 1 reaches a horizontal state. The human-machine interface displays the current posture, leveling status, and alarm information in real time. After leveling is completed, the system continuously monitors the tilt angle. If the tilt angle exceeds the limit due to ground settlement or load changes, the relevant support arm 21 is automatically fine-tuned to maintain horizontality. At the same time, the system and operation are interlocked. High-risk operations such as hoisting and jacking are prohibited when the system is not horizontal or when leveling is not completed. The support arm 21 also has pressure monitoring, soft leg protection, and overload alarm functions.
