Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communication technology, and more specifically, to a portable communication landscape tower. Background Technology

[0002] In the fields of emergency and field communications, traditional communication towers, due to their bulky structure, complex installation, and poor environmental adaptability, are unable to meet the rapid deployment needs of disaster relief and field operations. As communication technology develops towards portability and high mobility, the limitations of traditional equipment are becoming increasingly apparent.

[0003] Early communication towers were mostly fixed steel structures, requiring on-site assembly using heavy equipment such as cranes, with installation cycles lasting several days or even weeks. For example, in disaster sites such as earthquakes and floods, traditional communication towers often resulted in prolonged communication outages due to transportation difficulties and slow installation, missing the golden rescue period. Furthermore, their components were scattered (such as segmented tower sections and antennas requiring separate installation), necessitating a large workforce and scaffolding work, making installation impossible in rugged terrain or confined spaces (such as mountains or ruins), severely restricting the timeliness of emergency communications.

[0004] Traditional communication towers suffer from insufficient structural stability, making them ill-suited for complex ground environments. Their mobile wheels, often supported by elastic tires, are prone to sinking in soft ground such as mud and sand, requiring rescue by engineering machinery. In strong winds, the fixed support structure has limited overturning resistance, resulting in significant tower top vibrations and unstable antenna signal transmission. Data shows that traditional communication towers experience signal interruption rates exceeding 30% in winds of force 6 or higher, and in flood-affected areas, the equipment sinking failure rate reaches as high as 45%, failing to meet the reliability requirements of emergency communications.

[0005] Furthermore, traditional equipment has poor leveling capabilities, large antenna elevation angle errors, and limited communication distance. In mountainous areas and other terrain-undulating regions, the tower tilt angle cannot be adaptively adjusted, and the antenna signal is easily blocked by the terrain, reducing the communication coverage area by more than 50% compared to plains areas. At the same time, its fixed support structure cannot absorb ground vibrations, and vibrations from vehicle traffic or construction can cause antenna signal jitter, affecting the quality of voice and data transmission.

[0006] With the advancement of modern emergency communication system construction, higher demands are placed on the "rapid deployment, stable support, and all-terrain adaptability" capabilities of communication equipment. For example, fire rescue operations need to establish communication links within 30 minutes of arriving at the scene, but traditional equipment cannot meet this timeliness requirement; scenarios such as field exploration and military maneuvers require equipment to work stably in extreme environments such as slopes and swamps. Summary of the Invention

[0007] To overcome the above-mentioned defects, the present invention provides a portable communication landscape tower, which solves the technical problem that portable communication landscape towers are inconvenient to install on slopes in the prior art.

[0008] According to one aspect, at least one embodiment of the present invention provides a portable communication landmark tower, comprising: A trailer having a mounting platform and a plurality of wheels located below the mounting platform; A lifting frame is mounted on the installation platform, and an antenna is mounted on the upper side of the lifting frame; A telescopic support frame, the two ends of which are respectively connected to the fixed frame on the lifting frame and the installation platform through threaded connectors. Several telescopic support frames are provided to support the outer periphery of the lifting frame. A sliding platform is provided on the mounting platform. Several sliding platforms are provided and are located one-to-one below the telescopic support frame. Under the downward push of the threaded connector, the sliding platform can slide down to abut the ground so that the trailer moves up and drives the moving wheels to leave the ground.

[0009] For example, at least one embodiment of this disclosure provides a portable communication landscape tower, wherein the threaded connector has a hexagonal nut, and further includes: A locking component is disposed on the mounting platform and located on one side of the connector. The upper end of the locking component has a limiting part and the lower end has a connecting part. The limiting part is used to abut against the nut of the connector.

[0010] For example, at least one embodiment of this disclosure provides a portable communication landscape tower, wherein the locking element includes: A connecting pipe, wherein the connecting part is threadedly connected to the mounting platform, and the outer peripheral wall of the connecting pipe has a limiting groove; A telescopic rod, which is rotatably disposed inside the connecting pipe, and the upper end of the telescopic rod has the limiting part; A fastener is rotatably sleeved on the outer periphery of the telescopic rod. The fastener has an insertion part for inserting into the limiting groove to lock the telescopic rod and the fastener. The insertion part has a plurality of insertion holes spaced apart along the length direction. The plug-in, comprising at least two plug-ins, one of which passes through an insertion hole located above the connecting tube and is inserted into the telescopic rod, and the other plug-in passes through the insertion hole and is inserted into the telescopic rod.

[0011] For example, at least one embodiment of this disclosure provides a portable communication landscape tower, wherein the telescopic support frame includes: The expansion joint consists of several expansion joints that are sequentially connected, with two expansion joints located at both ends each having a connecting piece that is oscillating and connected to the installation platform and the lifting frame. A locking ring, with its two ends respectively disposed on two adjacent expansion joints, is used to lock the relative positions of the two adjacent expansion joints; A pull rope, one end of which is attached to the locking ring, and the other end of which is connected to the installation platform.

[0012] For example, at least one embodiment of this disclosure provides a portable communication landscape tower, wherein the locking ring includes: An arc-shaped fastener, comprising two arc-shaped fasteners, with one end of each arc-shaped fastener hinged together and the other end having a locking part; The device includes four snap-fit ​​half-rings. Each arc-shaped fixing member has two snap-fit ​​half-rings spaced vertically. The two sets of snap-fit ​​half-rings on the same arc-shaped fixing member are used to abut against the peripheral walls of two adjacent expansion joints. One end of the snap-fit ​​half-ring is oscillatingly connected to the inner side of the hinge end of the arc-shaped fixing member, and the other end is connected to the arc-shaped fixing member through a first elastic element. The first elastic element is used to provide the force for the snap-fit ​​half-ring to abut against the expansion joint. A fastener that passes through both of the locking parts and is used to lock two adjacent expansion joints.

[0013] For example, at least one embodiment of this disclosure provides a portable communication landscape tower, wherein a second elastic element is provided between the sliding platform and the mounting platform, the sliding platform has a sliding rod and a support platform located below the mounting platform, the sliding rod is slidably mounted on the mounting platform, and the bottom of the support platform has an anti-slip protrusion for contacting the ground.

[0014] For example, a portable communication landscape tower provided in at least one embodiment of this disclosure further includes: A pull rope assembly is connected to the lower end of the pull rope. The pull rope assembly has a plurality of sequentially arranged take-up rollers for winding the pull rope. Each take-up roller retracts the pull rope via a torsion spring. The pull rope assembly is connected to the installation platform via a tension rope.

[0015] For example, at least one embodiment of this disclosure provides a portable communication landscape tower, wherein the pull rope component includes: Mounting housing, which is connected to the tension rope; The mounting shaft is disposed within the mounting housing. The end face of the take-up roller has a mounting groove. The torsion spring is disposed within the mounting groove. The two ends of the torsion spring act on the take-up roller and the mounting shaft respectively, providing a force to maintain the tension of the pull rope. An anti-rotation component is provided. The mounting shaft has a mounting cavity at its center, and the cavity wall of the mounting cavity has a sliding hole. The anti-rotation component is slidably disposed in the mounting cavity. The anti-rotation component has an anti-rotation protrusion, which is slidably connected to the sliding hole. The end face of the take-up roller away from the mounting groove is provided with an anti-rotation groove. After the anti-rotation component slides, it can engage with the anti-rotation groove to restrict the circumferential rotation of the take-up roller.

[0016] For example, in at least one embodiment of this disclosure, a portable communication landscape tower is provided, wherein the pull rope component further includes: The third elastic element has one end acting on the cavity wall of the mounting cavity and the other end acting on the anti-rotation element, providing a force to keep the anti-rotation protrusion engaged with the anti-rotation groove. The anti-rotation element has a handle portion that penetrates one side of the mounting shell.

[0017] For example, a portable communication landscape tower provided in at least one embodiment of this disclosure further includes: A support frame is swaying around the mounting platform. The support frame is used to swing to abut against the ground to lock the trailer in position. A load-bearing component is swaying at the lower end of the support frame. The load-bearing component is connected to the ground by anchors and is equipped with counterweights.

[0018] The beneficial effects of the embodiments of the present invention are as follows: In this invention, the proposed communication tower utilizes a sliding platform at flood disaster sites, enabling the equipment to operate stably on soft, muddy ground covered in water, whereas traditional mobile wheeled vehicles are prone to sinking (requiring rescue by engineering machinery). This capability significantly reduces communication interruption recovery time.

[0019] In mountainous areas, the automatic leveling function of the sliding platform reduces the elevation angle error of the antenna, and the portable communication tower, due to its adjustable tilt angle, has an improved communication distance compared to traditional portable communication towers, ensuring real-time communication for mountain rescue command.

[0020] Traditional communication towers consist of disparate components, requiring on-site assembly of the tower body and antenna installation. The installation process relies on equipment such as cranes and scaffolding, resulting in a large investment of manpower and resources, and an installation cycle that can last for several days or even weeks. Traditional communication towers also have high requirements for the installation site. In environments with rugged terrain, narrow spaces, or soft ground, it is difficult to ensure the stability of the tower body, and installation may even be impossible.

[0021] The support frame can swing around the mounting platform. By adjusting the swing angle, it can make close contact with the ground on slopes and uneven surfaces, forming a stable triangular support structure. Even on steep slopes or gravelly ground, the tower body can be kept stable, effectively expanding the application range of the equipment.

[0022] The telescopic support frame is adjustable in length and angle to suit different environments, ensuring a stable connection with the lifting frame and installation platform under varying heights and space constraints. Simultaneously, the sliding platform's ground-hugging design increases the contact area with soft surfaces like swamps and beaches, distributing pressure and preventing equipment sinking, thus ensuring normal operation. Whether in urban streets, remote mountainous areas, or disaster sites, the portable communication observation tower can be quickly installed and operate stably, demonstrating exceptional environmental adaptability.

Therefore, they should not be construed as limitations on the present invention.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-10 As shown, it illustrates a portable communication landscape tower in one embodiment of the present invention.

[0032] In some examples, trailer 1 has casters 8 at the bottom and a platform 101 on top as a support base. A lifting frame 3 is vertically mounted on platform 101, with an antenna 4 mounted on top for signal transmission. A telescopic support frame 5 is a telescopic structure, with connectors 6 at both ends connecting a fixed frame 301 to platform 101. A sliding platform 7 is nested on platform 101 and slides down to the ground under the push of connectors 6, lifting trailer 1 and causing the casters 8 to leave the ground.

[0033] The telescopic design of the telescopic support frame 5 allows for adjustable support angles. It forms a hinge through the connector 6, distributing the horizontal load of the lifting frame 3 onto the platform 101, thereby reducing the amplitude of the tower top vibration.

[0034] When the connecting piece 6 pushes the slide table 7 down, the moving wheel 8 quickly leaves the ground. After the moving wheel 8 leaves the ground, the slide table 7 slides down and forms four support points with the ground (two slide tables on each side), transforming the elastic support (tire deformation) of the traditional moving wheel 8 into rigid support.

[0035] A disc spring assembly is installed between the slide 7 and the connector 6. When affected by ground vibration, the spring assembly absorbs energy through elastic deformation, reducing the vibration amplitude transmitted to the lifting frame 3 by 70% and ensuring the signal transmission quality of the antenna 4.

[0036] At flood disaster sites, the sliding platform 7 allows equipment to operate stably on soft, muddy ground covered in water, whereas traditional mobile wheeled vehicles are prone to sinking (requiring rescue by engineering machinery). This capability shortens communication interruption recovery time.

[0037] In mountainous areas, the automatic leveling function of the sliding platform 7 reduces the elevation angle error of the antenna 4. The portable communication tower, due to its adjustable tilt angle, has an improved communication distance compared to traditional portable communication towers, ensuring real-time communication for mountain rescue command.

[0038] Traditional communication towers consist of disparate components, requiring on-site assembly of the tower body and antenna installation. The installation process relies on equipment such as cranes and scaffolding, resulting in a large investment of manpower and resources, and an installation cycle that can last for several days or even weeks. Traditional communication towers also have high requirements for the installation site. In environments with rugged terrain, narrow spaces, or soft ground, it is difficult to ensure the stability of the tower body, and installation may even be impossible.

[0039] The support frame 2 can swing around the mounting platform 101. By adjusting the swing angle, it can make close contact with the ground on slopes and uneven ground, forming a stable triangular support structure. Even on steep slopes or gravelly ground, the stability of the tower body can be guaranteed, effectively expanding the application range of the equipment.

[0040] The telescopic support frame 5 is a telescopic frame, whose length can be adjusted according to actual environmental needs, and whose support angle can be flexibly changed to ensure a stable connection structure with the lifting frame 3 and the installation platform 101 under different heights and space constraints. Meanwhile, the sliding platform 7's downward-facing design increases the contact area with the ground in soft ground such as swamps and beaches, dispersing pressure and preventing equipment sinking, thus ensuring normal operation. Whether in urban streets, remote mountainous areas, or disaster sites, the portable communication landscape tower can be quickly installed and operate stably, demonstrating strong environmental adaptability.

[0041] In some examples, the threaded connector 6 has a hexagonal nut and also includes a locking element 9. The locking element 9 is located on the mounting platform 101 and on one side of the connector 6. It has a limiting part 901 at its upper end and a connecting part 902 at its lower end. The limiting part 901 is used to abut against the nut of the connector 6. The limiting part 901 of the locking element 9 cooperates with the connector 6 to form a mechanical limiting constraint. When the equipment is subjected to external vibration, the limiting part 901 can effectively prevent the connector 6 from rotating, thus preventing the support structure from failing due to the loosening of the connector 6. Compared with an unlimited design, the risk of connection loosening is reduced.

[0042] The connecting part 902 and the mounting platform 101 are connected by a high-strength thread or other reliable connection method to ensure that the limiting part 901 is securely installed. Even under long-term high-frequency vibration environment, the connecting part 902 can maintain a tight state to prevent the limiting part 901 from loosening and shifting, thereby continuously providing reliable limiting for the connecting part 6, ensuring the stable connection between the telescopic support frame 5 and the mounting platform 101 and the lifting frame 3, and improving the overall stability of the fixed structure of the trailer 1.

[0043] With the double protection of locking component 9, the reliability of the equipment in complex environments is significantly improved, and the safety hazards and equipment damage risks caused by loose connections are greatly reduced. This also reduces the frequency of maintenance and repair costs, extends the service life of the equipment, and ensures that the portable communication landscape tower can play a stable and efficient role in emergency communication, field operations and other scenarios.

[0044] In some examples, the locking member 9 includes: a connecting part 902 of the connecting tube 903 is threadedly connected to the mounting platform 101; a telescopic rod 905 is rotatably disposed inside the connecting tube 903, with a limiting part 901 at its upper end; a fixing member 906 is rotatably sleeved on the outer periphery of the telescopic rod 905, and has an insertion part 907 for inserting into the limiting groove 904 of the connecting tube 903 to lock the two together; the insertion part 907 has a plurality of insertion holes 908 spaced along its length; and at least two inserts 909, one of which passes through the insertion hole 908 above the connecting tube 903 and is inserted into the telescopic rod 905, and the other of which passes through the insertion hole 908 and is inserted into the telescopic rod 905.

[0045] The connecting part 902 of the connecting pipe 903 is threadedly connected to the mounting platform 101. This connection method provides a tightening force, ensuring a tight fit between the locking element 9 and the mounting platform 101. The self-locking characteristic of the thread effectively prevents loosening under vibration, impact, and other operating conditions. One end of the telescopic rod 905 is rotatably mounted on the connecting pipe 903, while the limiting part 901 at the other end can be adjusted in angle and position according to the position and shape of the connecting element 6, achieving precise fitting and limiting of the connecting element 6. Through telescopic adjustment, it can adapt to connecting elements 6 of different specifications and installation positions, improving the versatility of the locking element 9 and ensuring effective restriction of the rotation of the connecting element 6 in various installation scenarios.

[0046] The fixing member 906 is sleeved on the outside of the telescopic rod 905 and can rotate relative to it. Its insertion part 907 is located in the limiting groove 904, forming a linkage constraint with the connecting pipe 903. After the telescopic rod 905 is adjusted to position and limits the connecting member 6, the insert 909 passes through the insertion holes 908 at the upper and lower ends of the insertion part 907 and connects with the telescopic rod 905, firmly fixing the telescopic rod 905 in the fixing member 906. The length of the fixing member 906 is greater than the maximum telescopic length of the telescopic rod 905, which can prevent the telescopic rod 905 from excessively extending or retracting and losing its constraint. Multiple constraints further enhance the fixation of the telescopic rod 905, thereby ensuring that the limiting part 901 stably applies a limiting force to the connecting member 6.

[0047] The plug 909 features a dual-through-fixing design using the fastener 906, telescopic rod 905, and connecting pipe 903. This design tightly connects the telescopic rod 905 to the fastener 906 from both ends, significantly reducing the possibility of loosening or displacement of the telescopic rod 905 compared to a single fixing method. Even under extreme vibration or external impact, the cooperation between the plug 909 and the insertion hole 908 effectively distributes the force, maintaining the overall structural stability of the locking component 9 and ensuring that the limiting effect on the connecting component 6 remains effective. This, in turn, guarantees the stability of the trailer 1 and improves the reliability of the portable communication landscape tower in complex environments.

[0048] In some examples, multiple telescopic joints 501 are sequentially nested, with both ends of each joint 501 connected to the mounting platform 101 and the lifting frame 3 respectively via connecting pieces 502. The overall length of the telescopic support frame 5 can be adjusted according to actual needs. Whether in confined spaces or large open areas, the support angle and span can be flexibly changed, quickly adapting to lifting frames 3 of different heights and complex installation environments. This telescopic design breaks the limitations of traditional fixed support structures, enabling the equipment to find the optimal support solution under various terrain and spatial conditions, expanding the application range of portable communication landscape towers.

[0049] The locking ring 503 and the locking element 9 work together to form a double locking mechanism. The locking ring 503 surrounds two adjacent telescopic sections 501, initially fixing their relative positions; the locking element 9 further locks the telescopic sections 501, preventing them from sliding or loosening due to external forces during use. This double protection significantly enhances the structural stability of the telescopic support frame 5, ensuring that even under harsh conditions such as strong winds and vibrations, the support frame can continuously provide reliable support for the lifting frame 3 and the trailer 1, effectively improving the overall anti-overturning capability of the equipment and reducing safety risks caused by unstable support.

[0050] One end of the pull rope 505 is connected to the locking ring 503, and the other end is fixed to the installation platform 101 or other stable structure, providing additional tensile support for the telescopic support frame 5. When the equipment is subjected to external forces such as lateral wind or ground impact, the pull rope 505 absorbs and disperses part of the external force through its own tensile deformation, relieving the stress on the telescopic joint 501 and the locking components, and enhancing the toughness and buffering performance of the entire support structure. At the same time, the pull rope 505 can also limit the swing amplitude of the telescopic support frame 5 to a certain extent, further improving the stability of the equipment, reducing connection loosening or structural fatigue damage caused by component shaking, and extending the service life of the equipment.

[0051] In some examples, the fastener 510 passes through two locking portions 507, locking the ends of two adjacent expansion joints 501, and has a pull ring 504. One end of the pull rope 505 is connected to the pull ring 504. The continuous preload provided by the first elastic element 509 keeps the locking half-ring 508 in close contact with the expansion joint 501, forming a dustproof and waterproof sealing barrier. This design effectively resists dust intrusion and maintains minimal preload fluctuations within the temperature range during natural disasters, ensuring no loosening even in extreme environments.

[0052] The two snap-fit ​​half-rings 508 of the same arc-shaped fastener 506 are used to abut against two adjacent expansion joints 501, so that the snap-fit ​​half-rings 508 clamp one expansion joint 501 in pairs, thereby fixing the two adjacent expansion joints 501.

[0053] The hinged structure of the arc-shaped fastener 506, combined with the pull ring 504 design, shortens the locking operation time compared to traditional bolt connections, allowing for completion by a single person. Simultaneously, the reduced operating torque lessens the workload on-site, making it particularly suitable for scenarios requiring rapid deployment, such as emergency communications, thus improving equipment setup efficiency.

[0054] The adaptive oscillation capability of the snap-fit ​​half-ring 508 effectively compensates for manufacturing errors in the expansion joint 501, resulting in a more uniform distribution of contact stress. This feature controls the maximum stress of the expansion joint 501 within the material's yield strength, extending component life, reducing maintenance frequency, and extending replacement cycles.

[0055] The reusable design of the pull ring 504 serves as both the operating handle of the fastener 510 and the connection point of the pull rope 505, reducing the number of parts and lowering the weight of the equipment. This integrated design reduces the weight of a single locking ring 503, improving the portability of the equipment. At the same time, the auxiliary support of the pull rope 505 enhances the wind resistance of the telescopic support frame 5, thereby strengthening the overall structural stability.

[0056] In some examples, the second elastic element 11 connects the slide 7 to the mounting platform 101, enabling the slide to quickly reset after equipment operation. The sliding engagement between the slide rod 701 and the mounting platform 101 provides precise guidance for the lifting and lowering of the slide 7, ensuring smooth sliding and rising and preventing tilting or jamming. Simultaneously, this sliding structure allows the slide 7 to quickly respond to the push of the connecting element 6, improving equipment deployment efficiency.

[0057] The anti-slip protrusion 703 on the underside of the support platform 702 increases the friction with the ground, increasing the contact area between the slide platform 7 and the ground and improving the static friction coefficient. In complex ground environments such as mud and slopes, the anti-slip protrusion 703 can embed itself into the ground to prevent the slide platform 7 from sliding and shifting, ensuring stable support for the trailer 1, enabling the equipment to remain stable even in strong winds, and improving its anti-overturning ability.

[0058] In some examples, the combination of the take-up roller 1212 and the torsion spring 1204 enables the automatic retraction of the pull rope 505. When the equipment completes its work and needs to be withdrawn, the torsion spring 1204 releases its preload to drive the take-up roller 1212 to rotate, quickly winding and retracting the pull rope 505. This eliminates the need for manual handling, shortens the take-up time, improves equipment withdrawal efficiency, and reduces manpower input, making it particularly suitable for time-sensitive scenarios such as emergency communications.

[0059] The tension of the pull rope 505 can be changed by adjusting the preload of the torsion spring 1204. During equipment operation, the preload of the torsion spring can be adjusted according to actual wind force, terrain, and other environmental factors to ensure that the pull rope 505 maintains appropriate tension during fixation, providing stable auxiliary tension for the telescopic support frame 5 and enhancing the overall wind resistance and anti-overturning capability of the equipment. In windy conditions, adjusting the preload of the torsion spring can improve the stability of the equipment connection and ensure the continuous and reliable operation of the communication landscape tower.

[0060] Multiple sequentially arranged take-up rollers 1212 ensure that the pull rope 505 is neatly wound during the retrieval process, preventing knots and tangles. This orderly storage method reduces friction between the pull rope 505 and other components, reduces wear, extends the rope's service life, and lowers equipment maintenance costs.

[0061] The tension rope 12 is connected to the installation platform 101 via the tension rope 13. This flexible connection allows the tension rope 12 to adapt to slight swaying and displacement of the equipment under different terrains and working conditions. When the ground is uneven or the equipment is subjected to external forces and undergoes slight deformation, the tension rope 13 can buffer the impact through its own elastic deformation, preventing the tension rope 505 from breaking due to excessive stress caused by the rigid connection. At the same time, it ensures that the tension rope is always in an effective working state, improving the adaptability and reliability of the equipment in complex environments.

[0062] In some examples, the mounting housing 1201 is connected to the tension rope 13, and the torsion spring 1204 is installed in the mounting groove 1203 of the take-up roller 1212. Through its cooperation with the mounting shaft 1202, the preload can be automatically adjusted according to the stretching degree of the pull rope 505. When the pull rope 505 is stretched by an external force, the torsion spring 1204 compresses and stores energy; after the external force is removed, the torsion spring releases energy to drive the take-up roller 1212 to rotate, so that the pull rope always maintains a constant tension. This ensures that the telescopic support frame 5 can maintain a stable tension when releasing the rope, prevents the tension rope 13 from loosening, improves the support stability under complex working conditions, and enhances wind resistance.

[0063] The snap-fit ​​design between the anti-rotation component 1205 and the anti-rotation groove 1209 enables flexible control of the tension of the pull rope. When the anti-rotation protrusion 1208 snaps into the anti-rotation groove 1209, the take-up roller 1212 is locked, and the pull rope 505 maintains a fixed length, which is suitable for the equipment fixing stage. After the sliding anti-rotation component is de-snapped, the torsion spring 1204 drives the take-up roller to automatically retract the pull rope, shortening the winding time of a single pull rope and improving the equipment retraction efficiency.

[0064] The sliding hole 1207 in the mounting cavity 1206 precisely limits the anti-rotation protrusion 1208, ensuring that the anti-rotation component 1205 does not shift during sliding, thus avoiding the risk of uncontrolled pull rope due to misalignment. The fixed connection between the mounting shaft 1202 and the mounting housing 1201, combined with the flexible fixation of the tension rope 13, allows for quick disassembly and replacement of the pull rope component 12. When the torsion spring 1204 or the anti-rotation component 1205 malfunctions, the replacement time for a single component is shortened, improving efficiency by 7 compared to the traditional whole-component replacement method, effectively reducing maintenance costs and downtime.

[0065] In some examples, the third elastic element 1210 continuously pushes the anti-rotation element 1205, keeping the anti-rotation protrusion 1208 and the anti-rotation groove 1209 tightly engaged, ensuring that the pull rope 505 does not loosen during strong winds or equipment vibrations. Under conditions of strong winds or continuous vibrations generated by equipment operation, the third elastic element 1210 acts on the anti-rotation element 1205 with a constant thrust, keeping the anti-rotation protrusion 1208 and the anti-rotation groove 1209 tightly engaged, forming a rigid locking structure.

[0066] During long-term use, the anti-rotation protrusion 1208 and anti-rotation groove 1209 may experience minor wear due to friction. The third elastic element 1210, with its elastic deformation capability, automatically compensates for changes in the gap between components, continuously maintaining effective locking force. This adaptive characteristic extends the effective working life of the pull rope component 12, reducing maintenance frequency and costs.

[0067] Accidental collisions or misoperations during equipment operation may cause the anti-rotation component 1205 to slip abnormally. The continuous thrust of the third elastic element 1210 forms a physical barrier, requiring an additional external force greater than the preload to disengage the anti-rotation component from its latched state. This effectively prevents the risk of uncontrolled rope pulling due to accidental contact, providing dual protection for the safety of operators and equipment. When installing a communication tower, the rope can be released by pulling out the handle 1211 by overcoming the force of the third elastic element 1210.

[0068] In some examples, the support frame 2 is hinged to the edge of the mounting platform 101. After the four sets of support frames 2 are deployed, they form a tetrahedral support structure with the ground, increasing the anti-overturning moment and ensuring stable support in strong winds. The insertion holes 202 of the load component 201 can be used to pass through anchors (such as ground nails or expansion bolts), rigidly connecting the support frame 2 to the ground, effectively resisting external forces such as horizontal wind force and lateral impact force, thus improving the anti-overturning ability of the equipment in strong wind environments. At the same time, the load component 201 can bear the counterweight, further enhancing the vertical stability through gravity. In special environments such as soft ground, the addition of counterweight can effectively prevent the support frame 2 from sinking or sliding, ensuring the stability of the trailer 1 and the entire communication landscape tower.

[0069] The 202 socket design is compatible with various sizes of anchors, allowing for quick and easy fixing whether using expansion bolts on hard surfaces or ground stakes on soft surfaces such as soil and sand. Furthermore, the adjustable design of the counterweight (e.g., using detachable counterweight blocks) allows the equipment to flexibly adjust the counterweight weight according to actual terrain, wind conditions, and other factors, maintaining stability even in complex terrains such as slopes and swamps, thus expanding the equipment's application scenarios.

[0070] The load component 201 and the support frame 2 are connected by a swing connection. The load component 201 can be folded upward during equipment transportation to reduce space occupation. After arriving at the installation site, it can be quickly unfolded and the anchors and counterweights can be installed. Compared with the traditional fixing method, the deployment efficiency is improved, which is especially suitable for scenarios with high timeliness requirements such as emergency communication.

[0071] The load-bearing component 201 disperses the external force to the ground, reducing the stress on the support frame 2 itself and avoiding structural fatigue and damage caused by long-term stress.
