Description

Technical Field

[0001] This utility model belongs to the field of communication equipment technology, and more specifically, it relates to an outdoor communication signal tower. Background Technology

[0002] In outdoor communication systems, signal towers, as core infrastructure, play a crucial role in supporting various communication devices. To ensure effective signal propagation and coverage, equipment such as RRUs (Remote Radio Units) typically need to be installed at higher locations. In this case, simple and easy-to-install poles serve as important support devices within the signal tower system, allowing RRUs and other equipment to be securely erected at heights that meet signal propagation requirements. This high-level installation effectively reduces signal obstruction and interference from surrounding obstacles, thereby ensuring communication quality.

[0003] Because communication equipment such as RRUs need to be installed at high outdoor locations with the help of poles to ensure signal coverage, and this environment is often accompanied by complex weather conditions such as wind, rain, high and low temperatures, operators must conduct regular inspections and maintenance to ensure stable operation of the equipment. This process inevitably involves working at heights, and operators not only have to face the risk of falling from heights, but also have to overcome threats such as slipping and accidental shaking of equipment in harsh conditions such as wetness and strong winds, which significantly increases the safety hazards of maintenance work. Utility Model Content

[0004] To address the safety hazards associated with inspecting and maintaining RRUs installed at the top of poles, this invention proposes an outdoor communication signal tower to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an outdoor communication signal tower, including a mounting base, a pole fixedly mounted on the top of the mounting base, a lifting assembly provided on the outer surface of the pole, a winding assembly provided inside the mounting base, a traction assembly provided between the lifting assembly and the winding assembly, a locking assembly provided on the top of the mounting base corresponding to the winding assembly, and a communication device and a winding conductive assembly provided on the top of the lifting assembly.

[0007] The winding assembly pulls the lifting assembly through the traction assembly, so that when the winding assembly is rotated, the lifting assembly moves on the outer surface of the pole under the drive of the traction assembly, and the communication device moves synchronously under the drive of the lifting assembly.

[0008] Furthermore, the lifting assembly includes a lifting cylinder, which is movably connected to the upright. A lifting plate is fixedly connected to the outer surface of the lifting cylinder. A guide groove is provided on the outer surface of the upright. A guide strip is movably connected inside the guide groove. The guide strip is fixedly connected to the lifting cylinder. The communication device is fixedly installed on the top of the lifting plate.

[0009] Furthermore, the winding assembly includes a support cylinder, which is fixedly connected inside the mounting base. A rotating shaft is rotatably connected inside the support cylinder, and a steel cable winding reel is fixedly connected to the outer surface of the rotating shaft. One end of the rotating shaft passes through the mounting base and is fixedly connected to a rotating handle.

[0010] Furthermore, the traction assembly includes a steel cable, one end of which is fixedly connected to the outer surface of a steel cable reel, a mounting bracket is fixedly connected to the outer surface of the upright, and guide wheels are fixedly connected inside both the mounting bracket and the upright. The other end of the steel cable passes through several guide wheels and is fixedly connected to the lifting plate.

[0011] Furthermore, the locking assembly includes a locking hole, which is located at the top of the support cylinder and extends through the support cylinder and the rotating shaft. A locking rod is movably connected inside the locking hole. A storage cylinder is fixedly connected to the top of the mounting base. A pull plate is fixedly connected to the top of the locking rod through the storage cylinder. A push plate is fixedly connected to the outer surface of the locking rod. A spring is fixedly connected between the push plate and the storage cylinder. A ball bearing is rotatably connected to the bottom of the locking rod.

[0012] Furthermore, the retractable conductive component includes a mounting box, which is fixedly mounted on the top of the lifting plate. A wire winding reel is rotatably connected inside the mounting box, and a wire is provided on the outer surface of the wire winding reel. A connecting cavity is opened inside the wire winding reel. A conductive slip ring is fixedly mounted on one side of the mounting box. One end of the wire extends into the interior of the connecting cavity and is connected to the rotating end of the conductive slip ring. The other end of the wire extends to the outside of the mounting box and is fixedly connected to the top of the upright. The output end of the conductive slip ring is electrically connected to the communication equipment.

[0013] Furthermore, a storage box is fixedly installed on the other side of the mounting box, and the shaft of the wire winding reel extends into the interior of the storage box. A spiral spring is fixedly connected to the inner wall of the storage box and the outer surface of the shaft.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model rotates the winding end of the winding assembly, enabling the winding end to wind and release the traction assembly. During this process, the lifting assembly moves up and down along the upright under the traction of the traction assembly. The advantage of the above configuration is that by simply rotating the winding assembly, the lifting assembly can move the communication equipment from the upper side to the lower side of the upright. Therefore, when inspecting and maintaining the communication equipment, operators do not need to climb to heights, effectively improving the safety of the overall inspection and maintenance process.

[0016] 2. This utility model uses a rotating handle and shaft to drive the cable reel to rotate, allowing the wire wound on the outside of the reel to be continuously released as the lifting plate moves downward under the traction of the cable. This design ensures that the communication equipment remains connected to the wire when it is moved to the bottom of the pole. Simultaneously, when the communication equipment moves to the top of the pole, the tightened spiral spring expands, causing the reel to rotate and wind up the wire. This design keeps the wire between the top of the pole and the reel taut, preventing tangling and knotting during the lifting and lowering of the communication equipment.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-8 As shown, this utility model is an outdoor communication signal tower, including a mounting base 1, a pole 2 fixedly mounted on the top of the mounting base 1, a lifting assembly 3 provided on the outer surface of the pole 2, a winding assembly 4 provided inside the mounting base 1, a traction assembly 5 provided between the lifting assembly 3 and the winding assembly 4, a locking assembly 6 provided on the top of the mounting base 1 corresponding to the winding assembly 4, and a communication device 7 and a winding conductive assembly 8 provided on the top of the lifting assembly 3.

[0032] The winding assembly 4 pulls the lifting assembly 3 through the traction assembly 5, so that when the winding assembly 4 is rotated, the lifting assembly 3 moves on the outer surface of the upright 2 under the drive of the traction assembly 5, and the communication device 7 moves synchronously under the drive of the lifting assembly 3.

[0033] When inspecting and repairing the communication equipment 7, the locking component 6 is pulled, which allows the winding end of the winding component 4 to rotate. At this time, the traction component 5 wound on the winding end is continuously released. Meanwhile, the lifting component 3 moves downward under the traction of the traction component 5 and the gravity of the communication equipment 7. When the communication equipment 7 moves to the lower side of the upright 2 under the drive of the lifting component 3, the rotation of the winding end stops, and the inspection and repair of the communication equipment 7 begins.

[0034] By rotating the winding end of the winding assembly 4, the winding end can perform winding and releasing actions on the traction assembly 5. During this process, the lifting assembly 3 will move up and down along the upright 2 under the traction of the traction assembly 5. The advantage of the above setting is that by simply rotating the winding assembly 4, the lifting assembly 3 can move the communication equipment 7 from the upper side to the lower side of the upright. Thus, when inspecting and maintaining the communication equipment, the operator does not need to climb to a height, which effectively improves the safety of the overall inspection and maintenance process.

[0035] In one embodiment, the lifting assembly 3 includes a lifting cylinder 301, which is movably connected to the upright 2. A lifting plate 302 is fixedly connected to the outer surface of the lifting cylinder 301. A guide groove 303 is provided on the outer surface of the upright 2. A guide strip 304 is movably connected inside the guide groove 303. The guide strip 304 is fixedly connected to the lifting cylinder 301. The communication device 7 is fixedly installed on the top of the lifting plate 302.

[0036] When the lifting plate 302 is raised or lowered, the lifting cylinder 301 on the lifting plate 302 can slide on the outer surface of the upright 2. At the same time, the guide bar 304 can slide inside the guide groove 303 under the drive of the lifting cylinder 301. At this time, the guide bar 304 and the guide groove 303 can guide the lifting cylinder 301, so that the lifting plate 302 on the outer surface of the lifting cylinder 301 will not shake when it is raised or lowered. When the traction component 5 drives the communication device 7 to the top of the upright 2 through the lifting plate 302, the top of the guide bar 304 contacts the inner wall of the guide groove 303. This phenomenon ensures the overall stability of the lifting plate 302 when the communication device 7 is working at the top of the upright 2.

[0037] Furthermore, in practical applications, the core working principle of communication device 7 lies in its integrated RRU (Remote Radio Unit). The RRU receives digital baseband signals from the baseband processing unit via optical fiber. In the transmission path, the digital circuitry inside the RRU first converts the baseband signal from digital to analog, then up-converts it to a high-frequency radio frequency signal in the specified frequency band via a mixer, followed by amplification by a power amplifier, and finally radiates it into the air through an antenna to complete the wireless signal transmission. In the reception path, the weak wireless signal captured by the antenna is first amplified by a low-noise amplifier, then down-converted to an intermediate frequency or baseband signal by a mixer, followed by analog-to-digital conversion to form a digital baseband signal, and finally transmitted back to the baseband processing unit for processing via optical fiber.

[0038] In one embodiment, the winding assembly 4 includes a support cylinder 401, which is fixedly connected to the inside of the mounting base 1. A rotating shaft 402 is rotatably connected inside the support cylinder 401. A steel cable winding reel 403 is fixedly connected to the outer surface of the rotating shaft 402. One end of the rotating shaft 402 passes through the mounting base 1 and is fixedly connected to a rotating handle 404.

[0039] By turning the handle 404, the rotating shaft 402 can be rotated. The rotating shaft 402 can drive the steel cable winding reel 403 to rotate inside the mounting base 1, so that the steel cable winding reel 403 can wind up and release the traction component 5.

[0040] In one embodiment, the traction assembly 5 includes a steel cable 501, one end of which is fixedly connected to the outer surface of the steel cable reel 403. A mounting frame 502 is fixedly connected to the outer surface of the upright 2. Guide wheels 503 are fixedly connected to the interior of both the mounting frame 502 and the upright 2. The other end of the steel cable 501 passes through several guide wheels 503 and is fixedly connected to the lifting plate 302.

[0041] Guide wheels 503 are installed at both the top and bottom of the inside of the upright 2. This arrangement ensures that when both ends of the steel cable 501 extend to the outside of the upright 2, the steel cable 501 inside the upright 2 remains vertical. Furthermore, during winding and unwinding, the steel cable 501 does not come into contact with the upright 2, thus preventing wear on the steel cable 501. The guide wheels 503 inside the mounting bracket 502 support the steel cable 501, allowing the other end of the steel cable 501 to maintain a vertical position. The end is vertically connected to the lifting plate 302. This arrangement ensures the effectiveness of the steel cable 501 in pulling the lifting plate 302. When lifting the lifting plate 302, the steel cable winding reel 403 is rotated by turning the handle 404, so that the steel cable winding reel 403 can wind and release the steel cable 501. At this time, the steel cable 501 can rotate inside several guide wheels 503, and the lifting plate 302 begins to rise and fall under the traction of the steel cable 501.

[0042] In one embodiment, the locking component 6 includes a locking hole 601, which is located at the top of the support cylinder 401 and extends through the support cylinder 401 and the rotating shaft 402. A locking rod 602 is movably connected inside the locking hole 601. A storage cylinder 603 is fixedly connected to the top of the mounting base 1. The top end of the locking rod 602 extends through the storage cylinder 603 and is fixedly connected to a pull plate 604. A push plate 605 is fixedly connected to the outer surface of the locking rod 602. A spring 606 is fixedly connected between the push plate 605 and the storage cylinder 603. A ball bearing 607 is rotatably connected to the bottom end of the locking rod 602.

[0043] By rotating the handle 404 to rotate the cable winding reel 403, and causing the lifting plate 302 to move to the top of the upright 2 under the traction of the cable 501, the locking rod 602 corresponds to the locking hole 601. At this time, the spring 606 can push the push plate 605 downward, thereby causing the push plate 605 to drive the locking rod 602 downward. When the locking rod 602 moves into the locking hole 601, the locking rod 602 can lock the cable winding reel 403 through the rotating shaft 402, thus preventing the cable winding reel 403 from rotating arbitrarily, and also preventing the lifting plate 302 from falling under the gravity of the communication equipment 7. When it is necessary to perform maintenance and inspection on the communication equipment 7, it is only necessary to pull the locking rod 602 upward by pulling the pull plate 604, so that the locking rod 602 moves out of the locking hole 601, and then rotate the handle 404. The operation is relatively convenient.

[0044] In one embodiment, the retractable conductive component 8 includes a mounting box 801, which is fixedly mounted on the top of the lifting plate 302. A wire winding reel 802 is rotatably connected inside the mounting box 801. A wire winding reel 803 is provided on the outer surface of the wire winding reel 802. A connecting cavity 804 is opened inside the wire winding reel 802. A conductive slip ring 805 is fixedly mounted on one side of the mounting box 801. One end of the wire winding 803 extends into the connecting cavity 804 and is connected to the rotating end of the conductive slip ring 805. The other end of the wire winding 803 extends into the outside of the mounting box 801 and is fixedly connected to the top of the upright 2. The output end of the conductive slip ring 805 is electrically connected to the communication device 7.

[0045] As the lifting plate 302 moves downwards, the wire 803 is fixedly connected to the top of the upright 2, so the wire winding reel 802 can rotate continuously under the pull of the wire 803. At the same time, the wire 803 wound on the outside of the wire winding reel 802 can be continuously released. During the above operation, since the wire 803 and the conductive slip ring 805 inside the connecting cavity 804 are collinear with the axis of the wire winding reel 802, the wire 803 inside the connecting cavity 804 can rotate together with the wire winding reel 802, effectively avoiding the phenomenon of the wire 803 getting tangled. At the same time, with the assistance of the conductive slip ring 805, the wire 803 can always maintain the connection with the communication device 7. This setting allows the communication device 7 to always maintain the connection with the wire 803 when the height of the communication device 7 is adjusted.

[0046] In one embodiment, for the mounting box 801, a storage box 806 is fixedly mounted on the other side of the mounting box 801, the shaft of the wire winding reel 802 extends into the interior of the storage box 806, and a spiral spring 807 is fixedly connected to the inner wall of the storage box 806 and the outer surface of the shaft.

[0047] When the wire reel 802 rotates and continuously releases the wire 803, the spiral spring 807 can continuously tighten under the drive of the shaft head. When the communication device 7 moves to the top of the pole 2, the spiral spring 807 can continuously expand. At the same time, the expanding spiral spring 807 can drive the wire reel 802 to rotate, so that the wire reel 802 can wind up the wire 803. This setting ensures that the wire 803 between the top of the pole 2 and the wire reel 802 can always remain taut, thus avoiding the phenomenon of the wire 803 getting tangled or knotted when raising and lowering the communication device 7.

[0048] Through the above technical solution, 1. By rotating the winding end of the winding assembly 4, the winding end can perform winding and releasing actions on the traction assembly 5. During this process, the lifting assembly 3 will move up and down along the upright 2 under the traction of the traction assembly 5. The advantage of the above setting is that by simply rotating the winding assembly 4, the lifting assembly 3 can move the communication equipment 7 from the upper side to the lower side of the upright, so that when inspecting and maintaining the communication equipment, the operator does not need to work at height, effectively improving the safety of the overall inspection and maintenance process; 2. By rotating the handle 404 and the rotating shaft 402, the steel cable winding reel 403 is rotated, and the lifting plate 302 is pulled upwards by the steel cable 501. During downward movement, the wire 803 wound on the outside of the wire reel 802 can be continuously extended. This arrangement ensures that the communication device 7 remains connected to the wire 803 when it is moved to the bottom of the pole 2. Simultaneously, when the communication device 7 moves to the top of the pole 2, the tightened spiral spring 807 continuously expands. The expanding spiral spring 807 can drive the wire reel 802 to rotate, thereby allowing the wire reel 802 to wind up the wire 803. This arrangement ensures that the wire 803 between the top of the pole 2 and the wire reel 802 remains taut, thus preventing the wire 803 from becoming tangled or knotted when the communication device 7 is raised or lowered.
