Description

Technical Field

[0001] This invention relates to the field of fastening connection technology, specifically to a fastening and adjusting connection mechanism for tower loads. Background Technology

[0002] As a key supporting structure for power transmission lines, the stability of transmission towers directly affects the safe operation of the power grid. The fastening and adjusting connection mechanism for tower loads is a crucial component ensuring reliable connection between the tower and various loads (such as transmission lines and communication equipment). Traditional tower loads have a fixed angle after installation, making it difficult to flexibly adjust their direction and adapt to different operational needs such as obstacle clearing and monitoring. The installation process is cumbersome, hindering high-altitude operations, and the disassembly process is complex, impeding equipment maintenance and replacement, thus affecting operational efficiency. Towers are exposed to the outdoors for extended periods, making them susceptible to external impacts such as wind and vibration. Traditional fastening and adjusting connection mechanisms offer poor buffering performance for tower loads, and rigid connections can easily damage the tower loads, shortening equipment lifespan. Therefore, we have introduced a new fastening and adjusting connection mechanism for tower loads. Summary of the Invention

[0003] The purpose of this invention is to provide a fastening and adjusting connection mechanism for tower loads, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fastening and adjusting connection mechanism for a tower load, comprising a connection assembly installed on the tower, the connection assembly comprising a connection seat, a lifting seat slidably connected inside the connection seat, a buffer seat rotatably connected to the top of the lifting seat by a universal joint assembly, and a fastening bolt provided at the bottom of the connection seat, the top of the fastening bolt being screwed to the middle of the lifting seat, and the top of the buffer seat being used to install the tower load;

[0005] The connecting seat is inserted into the mounting plate on the iron tower. When the fastening bolts are locked with the lifting seat and the lifting seat moves down, the lifting seat drives the tensioning components that are evenly distributed on the side of the connecting seat to rotate and open until the tensioning components tension and fix the connecting seat and the mounting plate. At the same time, the hydraulic components on the lifting seat drive the rubber bladder on the tensioning components to expand and stick tightly to the lower end of the mounting plate.

[0006] When the lifting seat moves down, it presses down on the top of the buffer cylinder assembly, which is evenly distributed on the inner side of the top of the connecting seat. The buffer cylinder assembly drives the annular rubber buffer bladder on the outer side of the top of the connecting seat to expand and then stick tightly to the lower end of the lifting seat.

[0007] Preferably, the buffer seat includes a sealing cover, a column at the upper end of the sealing cover, and a columnar seat at the middle of the lower end of the sealing cover, and the tower load is installed on the top of the column.

[0008] Preferably, the universal joint assembly includes a screw centrally screwed to the top of the lifting seat and a ball joint fixed to the top of the screw;

[0009] The bottom of the columnar seat is provided with a hemispherical groove for accommodating the ball head. The bottom of the columnar seat is fixed with a limiting plate by a first screw. The upper end of the limiting plate is provided with an annular arc-shaped limiting groove, and the bottom of the ball head is located in the annular arc-shaped limiting groove.

[0010] The bottom of the screw extends through an annular arc-shaped limiting groove and is screwed with an adjusting nut.

[0011] Preferably, the connector includes a plug-in tube and a limiting seat disposed at the upper end of the plug-in tube. The plug-in tube is inserted into a plug-in hole on the mounting plate, and the limiting seat is located on the top of the mounting plate.

[0012] Preferably, the insert cylinder has several sets of receiving grooves evenly spaced on its side, and the tensioning assembly includes a gear movably connected to the top of the receiving groove by a rotating shaft and a tensioning arm fixed to the side of the gear, and the rubber bladder is embedded in the bottom outer side of the tensioning arm.

[0013] Preferably, a baffle is provided at the bottom of the inner side of the receiving groove.

[0014] Preferably, the lifting seat includes a lifting column inserted into the inner cavity of the insertion cylinder, the lifting column has vertical grooves evenly spaced on its side, the upper part of the vertical grooves has teeth, and the inner side of the gear extends into the vertical groove and meshes with the teeth;

[0015] The bottom of the plug tube has a through hole in the center for the fastening bolt, and the top of the fastening bolt is screwed into the threaded hole in the middle of the lifting column.

[0016] Preferably, the hydraulic assembly includes hydraulic grooves evenly distributed at the bottom of the lifting column, a hydraulic piston disposed in the hydraulic groove, a hydraulic rod disposed in the center of the bottom of the hydraulic piston, and a bottom sealing cover fixed to the bottom of the lifting column by a second screw.

[0017] The bottom of the hydraulic rod passes through the bottom sealing cover and is fixed to the bottom of the inner cavity of the plug-in cylinder;

[0018] The vertical groove is equipped with a hose that communicates with the top of the hydraulic groove. The other end of the hose is fixed to the inner side of the bottom of the tensioning arm, so that the rubber bladder communicates with the top of the hydraulic groove through the hose.

[0019] Preferably, the bottom of the inner cavity of the plug tube is provided with an annular groove for fixing the reset spring, the top of the reset spring is fixed to the bottom of the bottom sealing cover, and the reset spring is sleeved on the outside of the hydraulic rod.

[0020] Preferably, the inner side of the top of the limiting seat is provided with an inner groove, and the outer side of the top of the limiting seat is provided with an annular limiting groove for placing an annular rubber buffer bag;

[0021] The buffer cylinder assembly includes a buffer cylinder body evenly distributed in the inner groove, a buffer piston disposed in the middle of the buffer cylinder body, and an abutment rod disposed in the center of the top of the buffer piston, with the top of the abutment rod extending through and out of the buffer cylinder body.

[0022] The bottom of the buffer cylinder is connected to the annular rubber buffer bladder through a channel provided inside the limiting seat.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] This invention, through the design of the universal joint assembly, allows for 360-degree rotation even after the fastening bolts are tightened, meeting the installation and operation requirements of towers with different load angles. The rotation function and the tightening action are independent of each other, ensuring both connection stability and retaining flexible adjustment capabilities.

[0025] This invention requires only two steps for installation: insertion and positioning, and tightening the bolts. During bolt tightening, the tensioning assembly automatically opens, eliminating the need for manual adjustment and significantly improving installation efficiency. Disassembly is simple: reverse the bolt tightening process. Simultaneously, the tensioning assembly and rubber bladder automatically reset and release their fixation, allowing for quick separation of the connector and mounting plate, simplifying maintenance. The hydraulic and tensioning components work together to accommodate mounting plates of varying thicknesses and uneven surfaces, reducing installation environment compatibility and further enhancing ease of installation.

[0026] The buffer cylinder assembly of this invention is connected to the annular rubber buffer bladder, which can absorb and disperse the impact force generated by wind and vibration, preventing damage to the tower load and the fastening and adjustment connection mechanism, and extending the service life of the equipment. The annular rubber buffer bladder and the abutment rod jointly support the buffer seat, and with the uniform tensioning effect of the hydraulic components, ensures that the load is installed stably, reduces shaking, and ensures the normal operation of equipment such as laser obstacle clearing devices.

[0044] 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.

[0045] Example:

[0046] Please see Figures 1-16 This invention provides a technical solution: a fastening and adjusting connection mechanism for the load of a steel tower, including a connecting assembly 5 installed on the steel tower 1. A crossarm 2 is provided on the steel tower 1, and the crossarm 2 is a horizontal metal component (mostly angle steel or channel steel) fixed to the tower body of the steel tower 1. Its main function is:

[0047] Provide installation support points: support the weight of insulator strings, hardware and transmission lines, and raise them a certain distance away from the tower body (to ensure a safe insulation gap);

[0048] Separating conductors: Depending on the line voltage level and the number of conductors, crossarm 2 will be designed in multiple layers or groups to avoid short circuits between conductors of different phases.

[0049] The connecting component 5 includes a connecting seat 503, a lifting seat 502 that slides inside the connecting seat 503, a buffer seat 501 that is rotatably connected to the top of the lifting seat 502 by a universal joint assembly, and a fastening bolt 504 provided at the bottom of the connecting seat 503. The top of the fastening bolt 504 is screwed to the middle of the lifting seat 502, and the top of the buffer seat 501 is used to install the tower load 4.

[0050] The buffer seat 501 includes a sealing cover 50102, a column 50101 at the upper end of the sealing cover 50102, and a column-shaped seat 50103 at the middle of the lower end of the sealing cover 50102. The tower load 4 is installed on the top of the column 50101.

[0051] The tower load 4 can be a laser obstacle clearing device. The laser obstacle clearing device is a power operation and maintenance equipment based on high-energy laser technology. Its core component, the high-power fiber laser generator, can instantly form a high-temperature field, causing foreign objects to quickly reach their ignition or sublimation point, achieving decomposition, vaporization, or melting. It is used to remove foreign objects such as bird nests, kite strings, and plastic sheets from power transmission towers and their associated power transmission cables. It can achieve live, non-contact obstacle clearing, greatly improving the safety and efficiency of power transmission line operation and maintenance.

[0052] The universal joint assembly includes a screw 50106 centrally screwed to the top of the lifting seat 502 and a ball head 50105 fixed to the top of the screw 50106;

[0053] The bottom of the columnar seat 50103 is provided with a hemispherical groove 50104 for accommodating the ball head 50105. The bottom of the columnar seat 50103 is fixed with a limiting plate 50107 by a first screw 50108. The upper end of the limiting plate 50107 is provided with an annular arc-shaped limiting groove 50110, and the bottom of the ball head 50105 is located in the annular arc-shaped limiting groove 50110.

[0054] The bottom of the screw 50106 extends through the annular arc-shaped limiting groove 50110 and is screwed with an adjusting nut 50109. The bottom of the screw 50106 is screwed into the threaded hole 50202.

[0055] After the fastening bolt 504 is tightened, although the sealing cover 50102 of the buffer seat 501 is in contact with the top of the annular rubber buffer bladder 50307 and the abutment rod 50310, the universal joint assembly can still enable the buffer seat 501 to rotate 360 ​​degrees after overcoming the frictional force of the sealing cover 50102 contacting the top of the annular rubber buffer bladder 50307 and the abutment rod 50310, thus meeting the installation requirements of different angles of the tower load 4.

[0056] The design of the universal joint assembly is key, which includes a ball head 50105 fixed at the top of the screw 50106, which is adapted to the hemispherical groove 50104 and the annular arc-shaped limiting groove 50110 at the bottom of the columnar seat 50103.

[0057] The annular arc-shaped limiting groove 50110 at the upper end of the limiting plate 50107 only restricts the vertical displacement of the ball head 50105, and does not hinder the 360-degree horizontal rotation.

[0058] The bottom of the screw 50106 is screwed to the top of the lifting seat 502. The tightening of the fastening bolt 504 only drives the lifting seat 502 to move down to complete the fixation, without squeezing or locking the rotation space of the ball head 50105.

[0059] The combination of the ball head 50105 with the hemispherical groove 50104 and the annular arc-shaped limiting groove 50110 provides a structural basis for 360-degree rotation.

[0060] The connection method of the entire universal joint assembly is independent of the locking action of the fastening bolt 504. The fastening process only fixes the connecting seat 503 to the mounting plate 3 and does not affect the rotation function of the buffer seat 501.

[0061] The connector 503 includes a plug tube 50301 and a limiting seat 50306 provided on the upper end of the plug tube 50301. The plug tube 50301 is inserted into the plug hole 301 on the mounting plate 3, and the limiting seat 50306 is located on the top of the mounting plate 3.

[0062] The plug-in cylinder 50301 has several sets of receiving grooves 50302 evenly spaced on its side. The tensioning assembly includes a gear 50312 movably connected to the top of the receiving groove 50302 by a rotating shaft 50315 and a tensioning arm 50313 fixed to the side of the gear 50312. The rubber bladder 50314 is embedded in the bottom outer side of the tensioning arm 50313.

[0063] A baffle 50305 is provided at the bottom of the inner side of the receiving groove 50302. After the tensioning arm 50313 retracts into the receiving groove 50302, the baffle 50305 blocks the bottom of the tensioning arm 50313 to prevent the tensioning arm 50313 from retracting excessively.

[0064] The lifting seat 502 includes a lifting column 50201 inserted into the inner cavity of the plug-in cylinder 50301. Vertical grooves 50203 are provided at equal intervals on the side of the lifting column 50201. Teeth 50204 are provided on the upper part of the vertical grooves 50203. The inner side of the gear 50312 extends into the vertical groove 50203 and meshes with the teeth 50204.

[0065] The bottom of the plug-in cylinder 50301 is provided with a through hole 50316 for passing through the fastening bolt 504, and the top of the fastening bolt 504 is screwed into the threaded hole 50202 in the middle of the lifting column 50201.

[0066] The tensioning assembly connects the lifting seat 502 to the lifting seat 502 via gear 50312 meshing with teeth 50204 on the vertical groove 50203 on its side. This connection method allows the tensioning assembly to automatically rotate and open when the lifting seat 502 moves downward, thus achieving tension and fixation between the connecting seat 503 and the mounting plate 3. The advantage is that it eliminates the need for additional manual adjustment of the tension force, improving installation efficiency and reducing the complexity and uncertainty of manual operation. Simultaneously, the threaded drive and gear meshing ensure stable and reliable transmission, guaranteeing uniform application of tension force, enhancing connection stability, effectively preventing loosening of the connection during long-term use, and ensuring that the connection between the tower load 4 and the tower 1 remains reliable at all times.

[0067] The hydraulic assembly includes hydraulic grooves 50210 evenly distributed at the bottom of the lifting column 50201, hydraulic piston 50206 disposed in the hydraulic groove 50210, hydraulic rod 50207 disposed in the center of the bottom of the hydraulic piston 50206, and bottom sealing cover 50209 fixed to the bottom of the lifting column 50201 by a second screw 50208.

[0068] The bottom of the hydraulic rod 50207 passes through the bottom sealing cover 50209 and is then fixed to the bottom of the inner cavity of the insert sleeve 50301.

[0069] The vertical groove 50203 is provided with a hose 50205 that communicates with the top of the hydraulic groove 50210. The other end of the hose 50205 is fixed to the inner side of the bottom of the tensioning arm 50313, so that the rubber bladder 50314 communicates with the top of the hydraulic groove 50210 through the hose 50205.

[0070] The hydraulic assembly is connected to the rubber bladder 50314 in the tensioning assembly via a hose 50205. When the lifting seat 502 moves downward, the hydraulic assembly drives the rubber bladder 50314 to expand. The advantage of this connection method is that it allows for a more uniform distribution of tension force. After expansion, the rubber bladder 50314 adheres tightly to the lower end of the mounting plate 3, working together with the tensioning arm 50313 to secure the connecting seat 503 to the mounting plate 3 from multiple directions, greatly enhancing the reliability of the connection.

[0071] In addition, the deformable properties of the rubber bladder 50314 enable it to adapt to mounting plates 3 with different surface conditions. Even if the surface of the mounting plate 3 has a certain degree of unevenness or the thickness of the mounting plate 3 is not uniform, the rubber bladder 50314 can still fit tightly through its own deformation, ensuring the tightness and reliability of the connection.

[0072] The bottom of the inner cavity of the plug tube 50301 is provided with an annular groove 50317 for fixing the reset spring 50304. The top of the reset spring 50304 is fixed to the bottom of the bottom sealing cover 50209, and the reset spring 50304 is sleeved on the outside of the hydraulic rod 50207.

[0073] The inner side of the top of the limiting seat 50306 is provided with an inner groove 50309, and the outer side of the top of the limiting seat 50306 is provided with an annular limiting groove 50311 for placing an annular rubber buffer bladder 50307.

[0074] The buffer cylinder assembly includes a buffer cylinder body 50308 evenly distributed in the inner groove 50309, a buffer piston 50319 disposed in the middle of the buffer cylinder body 50308, and an abutment rod 50310 disposed in the center of the top of the buffer piston 50319, with the top of the abutment rod 50310 extending through the buffer cylinder body 50308.

[0075] The buffer cylinder 50308 has at least four sets, arranged in a cross shape in the front, back, left, and right directions.

[0076] The bottom of the buffer cylinder 50308 is connected to the annular rubber buffer bladder 50307 through a channel 50318 provided inside the limiting seat 50306.

[0077] The buffer cylinder assembly is connected to the annular rubber buffer bladder 50307 through the channel 50318 inside the limiting seat 50306. When the lifting seat 502 presses down on the buffer cylinder assembly, it drives the annular rubber buffer bladder 50307 to expand and press tightly against the lower end of the lifting seat 502. This connection structure can effectively buffer the impact force generated by wind, vibration and other factors in actual use, avoiding damage to the tower load 4 and the connecting mechanism, and extending the service life of the equipment. For example, in strong winds, the tower 1 will sway. At this time, the buffer cylinder assembly and the annular rubber buffer bladder 50307 can absorb and disperse these impact forces, reduce the impact on the tower load 4, ensure its normal operation, and effectively resist external vibration and impact, protecting the tower load 4.

[0078] The connecting seat 503 is inserted into the mounting plate 3 on the iron tower 1. When the fastening bolt 504 is locked with the lifting seat 502 and the lifting seat 502 moves down, the lifting seat 502 drives the tensioning components evenly distributed on the side of the connecting seat 503 to rotate and open until the tensioning components tension and fix the connecting seat 503 and the mounting plate 3. At the same time, the hydraulic components on the lifting seat 502 drive the rubber bag 50314 on the tensioning components to expand and stick tightly to the lower end of the mounting plate 3.

[0079] When the lifting seat 502 moves down, the lifting seat 502 presses down on the top of the buffer cylinder assembly that is evenly distributed on the inner side of the top of the connecting seat 503. The buffer cylinder assembly drives the annular rubber buffer bladder 50307 on the outer side of the top of the connecting seat 503 to expand and then stick tightly to the lower end of the lifting seat 502.

[0080] Specifically, when using it:

[0081] (a) Initial connection between connector 503 and mounting plate 3:

[0082] When installing the fastening and adjusting connection mechanism, first insert the plug-in sleeve 50301 of the connector 503 into the plug-in hole 301 of the mounting plate 3 on the tower 1. At this time, the limiting seat 50306 sits on top of the mounting plate 3, completing the initial positioning of the fastening and adjusting connection mechanism. This design allows the connector 503 to quickly and accurately mate with the mounting plate 3, providing a foundation for subsequent fastening operations.

[0083] (II) The lifting seat 502 drives the tensioning assembly to work:

[0084] After initial positioning, rotate and tighten the fastening bolt 504. Since the top of the fastening bolt 504 is screwed into the threaded hole 50202 in the middle of the lifting seat 502, and the top of the fastening bolt 504 passes through the through hole 50316 at the bottom of the plug-in cylinder 50301, the lifting seat 502 will gradually move down as the fastening bolt 504 rotates.

[0085] The lifting column 50201 of the lifting seat 502 has a vertical groove 50203 on its side. The teeth 50204 on the upper part of the vertical groove 50203 mesh with the inner side of the gear 50312 of the tensioning assembly. When the lifting column 50201 moves down, the teeth 50204 drive the gear 50312 to rotate around the rotating shaft 50315, and the tensioning arm 50313 fixed on the side of the gear 50312 rotates and opens accordingly. During the rotation of the tensioning arm 50313, a tensioning force is generated between the connecting seat 503 and the mounting plate 3, thereby fixing the two together. This method of converting rotational motion into linear motion through threaded transmission and gear meshing can realize the tensioning function. It has high transmission efficiency and a simple and reliable structure, and is widely used in mechanical connections.

[0086] (III) Hydraulic components assist in the expansion of the 50314 rubber bladder:

[0087] As the lifting seat 502 moves downward, the hydraulic components begin to operate. The bottom of the lifting column 50201 is provided with a hydraulic groove 50210. The hydraulic piston 50206 in the hydraulic groove 50210 moves upward relative to the lifting column 50201. The hydraulic rod 50207 at the bottom of the hydraulic piston 50206 is fixed to the bottom of the inner cavity of the insertion cylinder 50301, so the hydraulic piston 50206 will compress the liquid in the hydraulic groove 50210.

[0088] The top of the hydraulic groove 50210 is connected to the inner bottom of the tensioning arm 50313 via a hose 50205. The compressed liquid enters the rubber bladder 50314 through the hose 50205, causing it to expand. The expanded rubber bladder 50314 is tightly attached to the lower end of the mounting plate 3, further enhancing the friction and fixing effect between the connecting seat 503 and the mounting plate 3, and greatly improving the stability of the connection.

[0089] Even if the thickness of the mounting plate 3 is not uniform or the surface of the mounting plate 3 is uneven, as long as the fastening bolt 504 is tightened, the rubber bag 50314 will expand and stick tightly to the lower end of the mounting plate 3 as the tensioning arm 50313 rotates and opens. This will achieve the secure installation of the connecting component 5 and the mounting plate 3, thereby achieving the stable installation of the connecting component 5 and the iron tower 1.

[0090] (iv) Operation of the buffer cylinder assembly and the annular rubber buffer bladder 50307:

[0091] As the lifting seat 502 pulls the buffer seat 501 downward, the sealing cover 50102 of the buffer seat 501 presses down on the top of the abutment rod 50310. Under pressure, the buffer piston 50319 inside the buffer cylinder 50308 moves downward, causing the buffer solution inside the buffer cylinder 50308 to enter the annular rubber buffer bladder 50307 through the channel 50318 inside the limiting seat 50306, causing it to expand and press tightly against the lower end of the lifting seat 502.

[0092] After the fastening bolt 504 is fully tightened, the sealing cover 50102 completely covers the top of the connecting seat 503, serving to prevent water and dust.

[0093] The annular rubber buffer bladder 50307 plays a buffering and stabilizing role. On the one hand, it can reduce the rigid impact between the lifting seat 502 and the connecting seat 503 and extend the service life of the equipment. On the other hand, it further enhances the connection stability between the two and ensures that the connecting mechanism can work reliably under various working conditions.

[0094] The annular rubber buffer bladder 50307 and the abutment rod 50310 support the sealing cover 50102 together, thereby supporting the buffer seat 501, making the iron tower load 4 on the top of the buffer seat 501 more stable.

[0095] If the buffer seat 501 and the tower load 4 shake due to factors such as strong winds, the buffer solution can circulate within the buffer cylinder 50308 and the annular rubber buffer bladder 50307. This allows the annular rubber buffer bladder 50307 and the abutment rod 50310 to provide stable support for the buffer seat 501 and the tower load 4 through the sealing cover 50102, thus buffering the movement and quickly counteracting the shaking.

[0096] Disassembly working principle:

[0097] (a) Reverse operation to tighten bolt 504:

[0098] When it is necessary to disassemble the fastening and adjusting connection mechanism of the tower load 4, first perform the operation in reverse order of installation. Rotate the fastening bolt 504 in the opposite direction. Since the fastening bolt 504 is screwed to the middle of the lifting seat 502, as the fastening bolt 504 rotates in the opposite direction, and under the elastic force of the return spring 50304 on the plug-in cylinder 50301, the lifting seat 502 will gradually move upward.

[0099] During the upward movement of the lifting seat 502, the hydraulic components that were previously compressed due to the downward movement of the lifting seat 502 begin to recover. The hydraulic piston 50206 in the hydraulic groove 50210 moves downward to generate suction, causing the liquid in the rubber bladder 50314 to flow back to the hydraulic groove 50210 through the hose 50205. The rubber bladder 50314 gradually contracts, releasing the tight contact with the lower end of the mounting plate 3.

[0100] At the same time, the lifting seat 502 moves upward, causing the teeth 50204 on the vertical groove 50203 to move in the opposite direction, thereby causing the gear 50312 to rotate in the opposite direction around the rotating shaft 50315. The tensioning arm 50313 also rotates in the opposite direction to reset, until the tensioning arm 50313 retracts back into the receiving groove 50302, releasing the tension on the mounting plate 3.

[0101] Furthermore, as the lifting seat 502 moves the buffer seat 501 upward, the previously compressed buffer cylinder assembly also begins to recover. The sealing cover 50102 gradually disengages from the contact between the annular rubber buffer bladder 50307 and the abutment rod 50310. After the annular rubber buffer bladder 50307 deforms and retracts, the buffer solution inside the annular rubber buffer bladder 50307 flows back into the buffer cylinder 50308. The buffer piston 50319 inside the buffer cylinder 50308 moves upward, releasing the tight contact with the lower end of the lifting seat 502.

[0102] (ii) Separate the connecting seat 503 from the mounting plate 3:

[0103] After completing the above operations, the tensioning assembly, rubber bladder 50314, and annular rubber buffer bladder 50307 are all released from tension and tightness on the mounting plate 3 and lifting seat 502. At this time, there is no longer any fastening effect between the connecting seat 503 and the mounting plate 3, and the connecting seat 503 can be pulled out from the insertion hole 301 on the mounting plate 3 to complete the disassembly of the entire connection mechanism. This disassembly method is simple and convenient, and can quickly remove the connection mechanism from the tower 1, facilitating subsequent operations such as maintenance and replacement of the fastening and adjusting connection mechanism or the tower load 4.

[0104] During installation, the fastening and adjusting connection mechanism achieves a rapid and stable connection between the connecting seat 503 and the mounting plate 3 through the insertion and positioning of the connecting seat 503 and the mounting plate 3, as well as the coordinated work of components such as the lifting seat 502, tensioning assembly, hydraulic assembly, buffer cylinder assembly, and annular rubber buffer bladder 50307. This ensures reliable fixation between the tower load 4 and the tower 1. During disassembly, the fastening bolts 504 can be reversed to easily release the tightness and contact between the components, allowing for rapid removal of the connection mechanism.

[0105] The connection drive method between the various structures of the fastening and adjusting connection mechanism has significant advantages. The connection between the tensioning assembly and the lifting seat 502 enables automatic tensioning, improving installation efficiency and connection stability; the connection between the hydraulic assembly and the tensioning assembly makes the tension force distribution more uniform, adapting to different surface conditions of the mounting plate 3; the connection between the buffer cylinder assembly and the annular rubber buffer bladder 50307 effectively buffers the impact force and protects the equipment.

[0106] These advantages enable this fastening and adjusting connection mechanism to excel in improving installation efficiency, enhancing connection reliability, and extending equipment lifespan. In future tower construction and maintenance, this fastening and adjusting connection mechanism is expected to see wider application, providing a solid guarantee for the safe and stable operation of power systems. It also offers a valuable reference example for technological development and innovation in related fields, driving the entire industry towards greater efficiency, reliability, and safety.

[0107] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
