Description

Technical Field

[0001] This invention relates to the field of communication equipment technology, and in particular to an antenna hanger. Background Technology

[0002] With the iterative development of communication technology, the number of communication base stations being built is increasing day by day, and the demand for antennas used in communication base stations is also increasing. Generally, antennas are fixed at the top of the communication tower mast. The installation and dismantling of antennas involve high-altitude operations, which have low safety. In addition, antennas are usually placed in antenna boxes, which are heavy, and manual lifting of antenna boxes and loading and unloading of antennas are inefficient.

[0003] In related technologies, an antenna pylon is mounted on the end of the mast away from the ground. The antenna pylon includes a base, a support, and a height adjustment mechanism. The base is fixedly connected to the end of the mast away from the ground, and the support is connected to the base to support the antenna. The height adjustment mechanism is mounted on the support and is used to adjust the height of the antenna. The height adjustment mechanism includes an adjustment rod and a lifting device. The lifting device includes a pull rope, a pulley, and a handle. The pull rope passes around the pulley and is connected to the adjustment rod. The handle rotates to drive the pulley to rotate, thereby changing the length of the pull rope and thus raising or lowering the antenna.

[0004] However, the supports in the relevant technologies are all horizontal booms, that is, the extension direction of the horizontal boom is perpendicular to the side wall of the mast. The horizontal boom is generally a tubular component. When the gantry lifts the antenna box, the tubular boom is subjected to a large bending force and has low structural stability.

[0005] Furthermore, the antenna pylons in related technologies are installed at the mast ends in two forms: top mounting and side mounting. Top mounting involves the antenna pylon being installed at the top of the mast via connectors. This method results in lower installation stability and requires reinforcement of the connection between the antenna pylon and the connectors. In addition, the top of the mast is usually equipped with a lightning rod, and the top mounting method has low compatibility with lightning rods. Side mounting involves the antenna pylon being installed on the side wall of the mast via connectors. This method results in a larger bending moment between the antenna pylon and the mast, leading to lower installation stability. At the same time, the installation height of the side-mounted antenna pylon is insufficient, resulting in an insufficient antenna erection height. Summary of the Invention

[0006] This invention provides an antenna hanger for improving the structural stability of the antenna hanger on a mast equipped with a lightning rod, while ensuring that the antenna hanger has a high installation height on the mast equipped with the lightning rod, thereby ensuring the installation height of the antenna.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides an antenna hanger for use on a mast equipped with a lightning rod. The mast includes a base and a mast top plate located at the top of the base. The lightning rod includes a lightning rod base and a lightning rod body erected on the lightning rod base. The lightning rod base is fixed to the mast top plate. The antenna hanger includes a support base, a support frame, and a lifting device. The support base is fixed to the lightning rod base, and the support frame is fixed to the support base.

[0009] The support frame includes a hoisting rope and at least three support members. The at least three support members include a first support member for mounting the lightning rod body. The first end of the support member is connected to the support base. The second end of each support member points to different spatial directions. The first end of the hoisting rope is configured to be fixed to the mast. The second end of the hoisting rope is sequentially arranged at the second end of each support member and connected to the lifting device.

[0010] The lifting device is connected to the support frame, and the lifting device is configured to drive the antenna housing to rise and fall under the support of the support frame.

[0011] The technical solution provided by this invention has at least the following beneficial effects:

[0012] By placing the support frame at the top of the mast using a first support member capable of housing the lightning rod, the space utilization rate of the top of the mast for the installation of the hanger is improved. Furthermore, by using the first support member and the other support members in conjunction with the hoisting device and connecting them to the lifting device via ropes, the antenna housing is hoisted and the tension is ultimately transmitted to the mast body, reducing the bending moment on the support members when hoisting the antenna, thereby improving the structural stability of the antenna hanger.

[0013] In one possible implementation, the at least three supports further include at least two second supports, each second support being located on a different side of the first support, and the first support and each second support being coplanar.

[0014] In one possible implementation, the first end of the second support member is hinged to the support base.

[0015] In one possible implementation, the support base includes a base plate and two side plates, the two side plates being connected to each other on both sides of the base plate, and each of the two side plates having a first through hole, the first through holes on the two side plates being arranged opposite to each other;

[0016] The first end of the support member is located between the two side plates, and the support member has a second through hole corresponding to the first through hole. The second support member and the side plate are hinged to each other by a pivot passing through the first through hole and the second through hole.

[0017] In one possible implementation, a resilient fastener is also included, the resilient fastener having a connecting portion and two pivot portions;

[0018] The connecting part includes a connecting section and a limiting section located at opposite ends of the connecting section. The connecting section is arranged around the side of the first support member, and the limiting section is blocked on the outside of the side plate. The two rotating shafts are respectively arranged at opposite ends of the connecting part and are arranged corresponding to the first through holes on the two side plates to form the rotating shafts passing through the first through hole and the second through hole.

[0019] In one possible implementation, the first support member is a tubular member, and there is a first clearance space between the inner wall of the first support member and the lightning rod body. The first clearance space is configured to allow the first support member to move along its own diameter direction when it is subjected to tension.

[0020] There is a second clearance space between the pivot and the second through hole. The second clearance space is configured to allow the first support to move along its own axis when it is subjected to tension.

[0021] In one possible implementation, the second end of the suspension rope is sequentially wound around the second end of each of the support members;

[0022] The support member is provided with a limiting rod, the extension directions of the limiting rod and the support member are intersecting each other, and the distance between the limiting rod and the second end of the support member is less than the distance between the limiting rod and the first end of the support member. The suspension rope is wrapped around the side of the limiting rod opposite to the first end of the support member.

[0023] In one possible implementation, the limiting rod includes a first limiting rod correspondingly disposed on the second support member, wherein the extension directions of the first limiting rod and the second support member are perpendicular to each other; and / or,

[0024] The limiting rod includes a second limiting rod correspondingly disposed on the first support member. The second limiting rod includes a limiting part and a reinforcing part. The extending direction of the limiting part is perpendicular to the extending direction of the first support member. The reinforcing part is disposed on the side of the limiting part away from the suspension rope, and the reinforcing part is obliquely connected between the limiting part and the first support member.

[0025] In one possible implementation, a third limiting rod is also provided on the second support member that is furthest from the lifting device. The third limiting rod and the second support member are staggered and used to limit the movement distance of the hoisting rope in the direction away from the support seat.

[0026] In one possible implementation, the lifting device includes a pulley and a hoisting rope wound around the pulley, the pulley being tied to a second end of the hoisting rope, and the end of the hoisting rope away from the pulley being used to fix it to the antenna housing.

[0067] As described in the background section, the efficiency of hoisting, installing, and dismantling antennas on communication tower masts is low. In related technologies, antenna hangers are used to hoist antenna housings containing antennas. Lightning rods are usually erected at the top of the mast. The installation methods of antenna hangers on the mast include top mounting and side mounting. Top mounting involves installing the antenna hanger to the top of the mast through connectors, which has problems such as low installation stability and low compatibility with lightning rods. Side mounting involves installing the antenna hanger to the side wall of the mast through connectors, which has low installation stability and insufficient installation height of the antenna hanger, resulting in insufficient antenna erection height.

[0068] The inventors discovered that the main reason for this problem is that both top-mounted and side-mounted antenna pylons use a horizontal boom perpendicular to the mast sidewall as the lever arm to lift the antenna housing. The extension length of the horizontal boom is much greater than the width and thickness of the boom itself, resulting in a large bending moment when the boom lifts the antenna housing, causing insufficient lifting stability and insufficient installation stability of the pylon on the mast. Furthermore, in related technologies, whether it is top-mounted (attached to the top of the mast via connectors) or side-mounted (set on the mast sidewall), the lightning rod is regarded as a shield, resulting in insufficient compatibility with the lightning rod and insufficient utilization of space at the top of the mast.

[0069] To address the aforementioned technical problems, embodiments of the present invention provide an antenna hanger, which includes a support base, a support frame, and a lifting device. The support frame is mounted on the top of the mast by a first support member capable of housing a lightning rod, improving the space utilization rate of the top of the mast for hanger installation. Furthermore, the antenna housing is hoisted by the first support member and the other support members working together and connected to the lifting device by a hoisting rope, and the tension is ultimately transmitted to the mast body, reducing the bending moment on the support member when hoisting the antenna, thereby improving the structural stability of the antenna hanger.

[0070] To make the above-mentioned objectives, features, and advantages of the embodiments of the present invention more apparent and understandable, 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 a part of the embodiments of the present invention, and not all of them. 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.

[0071] Combination Figure 1The antenna hanger provided in this embodiment of the invention is applied to a mast 100 on which a lightning rod is installed. The mast 100 includes a base 110 and a mast top plate 120 located at the top of the base 110. The lightning rod 200 includes a lightning rod base 210 and a lightning rod body 220 erected on the lightning rod base 210. The lightning rod base 210 is fixed on the mast top plate 120. The antenna hanger includes a support 300, which is fixed on the lightning rod base 210. The support 300 includes a base plate 310 and two side plates 320. The base plate 310 and the side plates 320 are both rectangular. The two side plates 320 are perpendicularly connected to the two sides of the base plate 310, thereby forming a first cavity between the two side plates 320. The first cavity can be used as a space for engaging objects.

[0072] The base plate 310 has an opening 311, which is circular. The center of the opening 311 is located at the intersection of the center lines of the opposite short sides and the center lines of the opposite long sides on the surface of the base plate 310. The diameter of the opening 311 is larger than the diameter of the lightning rod body 220. The base plate 310 of the support base 300 is fixed to the lightning rod chassis 210 by fitting the lightning rod body 220 through the opening 311.

[0073] It should be noted that the support base 300 and the lightning rod chassis 210 can be fixed by pressing the base plate 310 onto the lightning rod chassis 210 with a heavy object, or the base plate 310 can be welded and / or riveted onto the lightning rod chassis 210.

[0074] Those skilled in the art will understand that lightning rods are of industry-standard dimensions; for example, the diameter of the lightning rod body 220 is 10-20mm, which can be 10mm, 16mm, or 20mm.

[0075] As an example, the base plate 310 is 78mm long and 26mm wide, which means the distance between the two side plates 320 is 26mm, and the thickness of the side plates 320 is 3mm; the inner height of the two side plates 320 is 26mm, which means the distance from the surface of the two side plates 320 away from the base plate 310 to the surface connected to the base plate 310 is 26mm, the thickness of the base plate 310 is 3mm, and the outer height of the two side plates 320 is 29mm, which is the distance from the surface of the two side plates 320 away from the base plate 310 to the surface connected to the base plate 310 plus the thickness of the base plate 310.

[0076] The antenna pylon also includes a support frame 400, which is fixed to a support base 300. The support frame 400 includes a suspension rope 420 and three support members 410. The first end of each support member 410 is connected to the support base 300, and the second end of each support member 410 points to a different spatial direction. Each support member 410 includes a first support member 410 for mounting the lightning rod body 220 and second support members 410 located on both sides of the first support member 410. Figure 1The first support member 410 is a support tube 411, and the second support member 410 is a support column 412. The lightning rod body 220 is installed in the cavity of the support tube 411. The first end of the support tube 411 and the first end of the support column 412 are engaged between the two side plates 320 of the support base 300. For example, the outer diameter of the support tube 411 and the support column 412 is equal to the distance between the two side plates 320 to improve the engagement stability between the first end of the support tube 411 and the first end of the support column 412 and the two side plates 320.

[0077] In another example, the inner diameter of the support tube 411 is the same as the diameter of the opening 311, and the wall thickness of the support tube 411 is equal to the minimum distance between the outer edge of the opening 311 and the inner wall of the side plate 320. This design allows the second tube body and the support seat 300 with the opening 311 to be better engaged and assembled. At the same time, the weight of the second tube body is used to press against the base plate 310, which improves the stability of the support seat 300 on the lightning rod chassis 210 and provides a radial limit for the support seat 300 along the support tube 411 to prevent the support seat 300 from tipping over.

[0078] For example, the support tube 411 is an aluminum round tube to ensure the lightweight structure of the support member 410. The support tube 411 is 680mm long, 20mm inner diameter, 26mm outer diameter, and 3mm thick. The diameter of the support tube 411 is 10-30mm, which can be 10mm, 20mm or 30mm. Correspondingly, the diameter of the opening 311 is 10-30mm, which can also be 10mm, 20mm or 30mm.

[0079] As an example, the diameter of the opening 311 is 20mm, the inner diameter of the second tube is 20mm, the wall thickness of the second tube is 3mm, that is, the outer diameter of the second tube is 26mm, and the minimum distance between the outer edge of the opening 311 and the inner wall of the side plate 320 is 3mm.

[0080] The second end of the support tube 411 points in the direction of extension of the lightning rod body 220. The second end of the support column 412 located on the left side of the support tube 411 points in a direction perpendicular to the direction of extension of the lightning rod body 220. The reverse extension line of the second end of the support column 412 located on the right side of the support tube 411 is oblique to the axis of the lightning rod body 220.

[0081] The lifting rope 420 is a double-strand loop rope with two binding ends. The double-strand loop rope can be formed by connecting the ends of two ropes correspondingly, or by wrapping a single rope around itself. The lifting rope 420 includes a first lifting rope 421, a second lifting rope 422, an anchor rope 423, and a pull rope 424. The first end of the anchor rope 423 is tied to the base rod 110, and the second end of the anchor rope 423 is tied to the second end of the support column 412 located to the left of the support pipe 411. The two ends of the first lifting rope 421 and the second lifting rope 422 are respectively tied to the second end of the support column 412. The second end of the support tube 411 is connected to the support column 412 located on the right side of the support tube 411. One end of the rope 424 is tied to the second end of the support column 412 located on the right side of the support tube 411, and the other end is tied to the lifting device 500. This allows the lifting device 500 to lift the antenna box 600 under the support of the support frame 400. At the same time, the antenna hanger transmits the reverse force of lifting the antenna box 600 to the mast 100 through the cooperation of the support member 410 and the hoisting rope, which reduces the bending moment on the support frame 400 and improves the structural stability of the antenna hanger.

[0082] Preferably, both the support column 412 and the support tube 411 are cylindrical, which can significantly reduce the friction and wear of the support member 410 on the suspension rope 420 compared with the prism structure.

[0083] Optionally, the support base 300, support tube 411 and support column 412 are all made of aluminum alloy, preferably 7 series aluminum alloy, and more preferably 7 series aluminum alloy with grade 7075-T651, which has a yield strength greater than 500MPa, ensuring that the overall hanger is lightweight while also having high mechanical strength.

[0084] Continue to combine Figure 1 The support tube 411 and the support columns 412 located on the left and right sides of the support tube 411 are coplanar. It can be seen that the support tube 411, the support columns 412 and multiple suspension ropes constitute a "fan-shaped" or "radial" support frame 400 structure. When the antenna box 600 is hoisted, the support frame 400, with the single tension surface formed by the coplanar support tube 411 and the support columns 412, ensures that the support tube 411 and the support columns 412 are only subjected to axial force. Compared with the horizontal boom, this significantly reduces the bending moment of the hoist. Moreover, the "fan-shaped" support frame 400, with each fan bone connected by the suspension ropes 420, that is, each support member 410, achieves a combination of long lever arm and short moment, reducing the pulling force required for the antenna hoist to hoist the antenna box 600. In other words, it improves the hoisting efficiency while ensuring the structural stability of the antenna hoist.

[0085] In some embodiments, combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5Each of the two side plates 320 is provided with a first through hole 321. The first through holes 321 on the two side plates 320 are arranged opposite to each other. Three sets of first through holes 321 are spaced apart along the length of the side plate 320. The first through hole 321 in the middle is rectangular, for example, a rectangular first through hole 321 with a length of 6mm and a width of 4mm.

[0086] The second support member 410 consists of two support columns 412 located on both sides of the first support member 410. One end of the support column 412 is located between the two side plates 320, and the end of the support column 412 located between the two side plates 320 has a second through hole 413 corresponding to the first through hole 321. The support column 412 and the side plate 320 are hinged to each other by a rotating shaft 414 passing through the first through hole 321 and the second through hole 413.

[0087] By hinged to the support base 300, the bending force on the support column 412 when hoisting the antenna housing 600 can be further reduced. At the same time, the support column 412 located on the side of the support tube 411 near the antenna housing 600 can be adjusted to rotate toward the support tube 411, thereby pulling the hoisted item closer to the mast 100 for easy access. In addition, the support column 412 can also be retracted to both sides of the support tube 411 to reduce the space occupied by the support frame 400, making it easier to carry and store the hoist, as well as to install and disassemble it on the mast 100.

[0088] Preferably, the rotating shaft 414 is a flat-headed pin, and the end of the flat-headed pin is provided with a bolt hole, and a bolt wire 415 is inserted into the bolt hole. This structure can prevent the flat-headed pin from slipping off the first through hole 321 and the second through hole 413.

[0089] More preferably, the flat-head pin is made of stainless steel to maximize the hinge stability between the first and third tubes and the support 300.

[0090] In more possible embodiments, the antenna hanger also includes an elastic fastener 700. For example, the elastic fastener 700 can be a metal wire, preferably an iron wire, which is economical and practical. The elastic fastener 700 is used to elastically engage the support tube 411 with the support base 300. The elastic fastener 700 has a connecting part 710 and two rotating shaft parts 720.

[0091] The connecting portion 710 includes a connecting section 711 and a limiting section 712 located at opposite ends of the connecting section 711. The connecting section 711 is arranged around the side of the first support member 410. The limiting section 712 is blocked on the outside of the side plate 320. Two rotating shafts 414 are respectively arranged at opposite ends of the connecting portion 710 and are arranged corresponding to the first through holes 321 on the two side plates 320 to form rotating shafts 414 passing through the first through hole 321 and the second through hole 413.

[0092] In this way, the two pivots 414 of the elastic fastener 700 not only achieve elastic engagement between the support tube 411 and the two side plates 320 of the support base 300, thus strengthening the connection stability between the support tube 411 and the support base 300, but also ensure the flexibility of the elastic fastener 700 after it is installed on the support tube 411 and the support base 300.

[0093] As one possible implementation, the first through hole 321 is provided with grooves on the inner walls of opposite sides along the axial direction of the support tube 411, and the portions of the two rotating shafts 414 located in the first through hole 321 are provided with protrusions. The protrusions are used to engage with the grooves to further prevent the elastic fastener 700 from slipping off the support tube 411 and the side plate 320. For example, the grooves are hemispherical grooves and the protrusions are hemispherical protrusions.

[0094] As an example, there is a first clearance space 430 between the inner wall of the support tube 411 and the lightning rod body 220. In this way, the support tube 411 can rotate at a small angle relative to the support base 300, that is, the support tube 411 can move radially relative to the lightning rod body 220 to compensate for the bending moment generated on the support tube 411 when the first rope or the second rope pulls the support tube 411.

[0095] In another embodiment, a second clearance space is provided between the pivot portion 720 and the second through hole 413, that is, the diameter of the second through hole 413 is larger than the diameter of the pivot portion 720 to form a second clearance space. The second clearance space is configured to allow the support tube 411 to move along its own axis when it is subjected to tension, so as to offset part of the bending moment of the support tube 411. At the same time, the self-weight of the support tube 411 is used to further strengthen the clamping force on the support seat 300.

[0096] As an example, the elastic buckle 700 is made of flexible iron wire with a diameter of 4mm and a length of 124mm. The connecting section 711 after being formed is 36mm, the limiting section 712 is 32mm, and the length of the rotating shaft 414 is 6mm.

[0097] Combination Figure 1 , Figure 2 , Figure 6 , Figure 8 and Figure 9In more cases, the support tube 411 and the support columns 412 located on both sides of the support tube 411 are provided with limiting rods 800. Correspondingly, the second ends of the support tube 411 and the support columns 412 located on both sides of the support tube 411 are provided with limiting holes for installing the limiting rods. The limiting rods 800 are perpendicular to the side walls of the support tube 411 and the support columns 412, and the distance between the limiting rods 800 and the second ends of the support tube 411 and the support columns 412 is less than the distance between the limiting rods and the support tube 411 and the support columns 412. The distance between the first ends, the end of the anchor rope 423 away from the base rod 110 and the end of the first lifting rope 421 are wrapped around the first end of the support column 412 on the left side of the limiting rod away from the support tube 411, the other end of the first lifting rope 421 and the first end of the second lifting rope 422 are wrapped around the first end of the limiting rod 800 away from the support tube 411, and the other end of the second lifting rope 422 and the pull rope 424 are wrapped around the first end of the support column 412 on the right side of the limiting rod 800 away from the support tube 411.

[0098] Thus, multiple limiting rods 800 can limit the movement of multiple lifting ropes along the axial direction of the support pipe 411 and the support column 412, preventing the lifting ropes from slipping in the direction close to the support seat 300 when the support frame 400 is under force. Furthermore, the protrusions of the limiting rods 800 passing through the support pipe 411 and the support column 412 can also provide a reinforcement position for the lifting ropes.

[0099] Optionally, the second end of the lifting rope 420 is tied to the limiting rod 800 by a binding rope, which can further improve the connection stability of the lifting rope 420 on the support member 410.

[0100] Preferably, the binding rope is a strong and tough thin rope with a diameter of 0.5-2mm. The strong and tough thin rope is made of synthetic fiber or metal wire, has a small volume and high tensile and compressive strength. For example, the diameter of the strong and tough thin rope is 0.5mm, 1mm or 2mm.

[0101] In a preferred embodiment, the limiting rod 800 includes a first limiting rod 810 correspondingly disposed on the support column 412, and the extension directions of the first limiting rod 810 and the support column 412 are perpendicular to each other.

[0102] The limiting rod 800 also includes a second limiting rod 820 correspondingly disposed on the support tube 411. The second limiting rod 820 includes a limiting part 821 and a reinforcing part 822. The extending direction of the limiting part 821 is perpendicular to the extending direction of the support tube 411. The reinforcing part 822 is disposed on the side of the limiting part 821 opposite to the first lifting rope 421 and the second lifting rope 422, and the reinforcing part 822 is obliquely connected between the limiting part 821 and the support tube 411. Figure 7As shown, the second limiting rod 820 and the support tube 411 form two triangular limiting structures by enclosing the opposite side walls. The limiting part 821 and the reinforcing part 822 of the second limiting rod 820 can be integrally formed or can be formed by connecting two tubes or rods. In this way, compared with the structure of a single horizontal bar as the limiting rod, the reinforcing part 822, as a reinforcing diagonal waist, improves the structural stability of the limiting rod.

[0103] In other possible embodiments, the reinforcing part 822 of the second limiting rod 820 is welded to the side wall of the support tube 411, and one end of the limiting part 821 of the second limiting rod 820 is engaged in the limiting hole provided in the support tube 411. The limiting parts 821 of the two second limiting rods 820 located on both sides of the support tube 411 leave a third clearance space in the cavity of the support tube 411 along the diameter direction of the support tube 411. Compared with the method of the second limiting rod 820 directly passing through the support tube 411, it can prevent the limiting part 821 of the second limiting rod 820 from becoming the blocking part of the lightning rod body 220 in the cavity of the support tube 411.

[0104] It should be noted that when the length of the lightning rod body 220 in the vertical direction is greater than the height of the grid part, the grid part will hinder the installation of the lightning rod body 220 in the cavity of the support pipe 411. That is, when the support pipe 411 is fitted with the lightning rod body 220, the grid part will contact the lightning rod body 220 along the axial direction of the support pipe 411, thereby hindering the installation of the support pipe 411.

[0105] Optionally, the engagement point between the limiting part 821 of the second limiting rod 820 and the support tube 411 is further provided with a circumferential weld to further improve the connection strength between the limiting part 821 of the second limiting rod 820 and the support tube 411.

[0106] Based on the above embodiment, an improvement can be made by providing a third limiting rod 830 on the support column 412 located on the left side of the support tube 411, that is, the support column 412 furthest from the lifting device 500. The third limiting rod 830 is perpendicular to the support column 412 and is located on the side of the first limiting rod 810 away from the support seat 300, so as to limit the movement distance of the first hoisting rope 421 and / or anchor rope 423 in the direction away from the support seat 300 and prevent the rope from slipping off the support column 412.

[0107] Those skilled in the art will understand that the first hoisting rope 421 and the anchor rope 423 may be wound around a section between the first limiting rod 810 and the third limiting rod 830 of the support column 412, and the length of this section may be 5-15mm, for example, 5mm, 10mm or 15mm.

[0108] The lifting device 500 includes a pulley 510 and a hoisting rope 520 wound around the pulley 510. The pulley 510 is connected to the second end of the hoisting rope. The end of the hoisting rope 520 away from the end wound around the pulley 510 is used to fix it to the antenna housing 600. That is, after the hoisting rope 520 is wound around the pulley 510, two free ends extend out. The two free ends are respectively fixed to the top and bottom of the antenna housing 600 on which the antenna is mounted. For example, the end of the pulley 510 connected to the support column 412 is provided with a hanging hole. One end of the pull rope 424 is threaded through the hanging hole, and the other end is wound around the second end of the support column 412 to hang the pulley 510 on the second end of the support column 412.

[0109] For example, the antenna housing 600 is provided with hanging holes at the top and bottom, and the two free ends of the sling 520 are respectively tied to the hanging holes. The sling 520 is used to receive the pulling force from the pull rope 424 to suspend the antenna housing 600.

[0110] It should be noted that the total length of the hoisting rope 520 is greater than or equal to the height of the pulley 510, wherein the height of the pulley 510 is based on the lifting plane; preferably, the total length of the hoisting rope 520 is greater than or equal to twice the height of the pulley 510, that is, the loop length of the hoisting rope 520 is greater than or equal to once the height of the pulley 510.

[0111] Based on the above embodiment, an improvement can be made by providing a tensioning assembly 900 on the anchor rope 423 to improve the connection stability and flexibility of the anchor rope 423 between the support column 412 and the base rod 110. The tensioning assembly 900 includes a tensioner 910, such as... Figure 1 and Figure 6 As shown, the rope tensioner 910 has a box-like structure. Both ends of the rope tensioner 910 have rope holes. The anchor rope 423 is threaded through the rope holes into the rope tensioner 910. The end of the rope tensioner 910 closest to the mast 100 is the fixed end, and the end of the rope tensioner 910 furthest from the mast 100 is the tensioning end, which is used to adjust the tension of the rope segment between the anchor rope 423 and the support column 412.

[0112] In this way, when hoisting the antenna housing 600, the length of the anchor rope 423 can be increased by the rope tensioner 910, that is, the rope section between the anchor rope 423 and the support column 412 is loosened to match the tension on the support column 412, so that the support column 412 rotates clockwise at a small angle relative to the support base 300, so that the torque on the support column 412 is transmitted to the part near the hinge end with the support base 300, reducing the bending moment on the support column 412 while increasing the pressure of the support base 300 on the lightning rod chassis 210, and strengthening the stability of the support base 300 on the lightning rod chassis 210.

[0113] As another example, the tensioner 910 is only passed through a single strand of the anchor rope 423. In this way, compared with the structure in which the tensioner 910 is only passed through a double strand of the anchor rope 423, when hoisting the antenna housing 600, the tensioner 910 only needs to bear the tension of one strand of the double strand of the anchor rope 423, that is, only bear half of the tension of the anchor rope 423 on the support column 412, which can reduce the requirements for the structural strength of the tensioner 910.

[0114] Preferably, the rope tensioner 910 is a small, retractable rope tensioner 910, which is smaller, lighter, and more convenient to use than the traditional rope tensioner 910.

[0115] In another preferred embodiment, the tensioning assembly 900 further includes a rope buckle 920 disposed at one end of the anchor rope 423 near the base rod 110, wherein the two strands of the anchor rope 423 near the base rod 110 are wrapped and fastened to one side of the base rod 110 by the rope buckle 920. Figure 1 As shown, the double-stranded section of the anchor rope 423 is wrapped around the lower end of the anchor rope 423 by the rope buckle 920, thereby binding the double-stranded section of the anchor rope 423 to the lower end of the mast 100, so as to form an anchor point on one side of the mast 100, which can enhance the connection stability between the anchor rope 423 and the mast 100.

[0116] For example, the mast 100 has a climbing crossbar 130 at its lower end, and the double-stranded rope segment at the lower end of the anchor rope 423 can be tied to the climbing crossbar 130; the rope buckle 920 is a stainless steel gourd buckle.

[0117] As a preferred implementation method, combined with Figure 1 A safety rope 425 is also provided between the support column 412 on the right side of the support tube 411 and the pulley 510. One end of the safety rope 425 is tied to the second end of the support column 412, and the other end of the safety rope 425 is threaded through the hanging hole and adjacent to the pull rope 424. When the antenna box 600 is hoisted, the load brought by the antenna box 600 is mainly borne by the pull rope 424. The addition of the safety rope 425 can replace the pull rope 424 to bear the tension of the antenna box 600 when the pull rope 424 breaks, thus preventing the antenna box 600 from falling and being damaged.

[0118] In some embodiments, pulley 510 is an outdoor mountaineering pulley, which can bear 2000-2500kg, such as 2000kg, 2200kg or 2500kg.

[0119] This design allows for the use of small and lightweight outdoor mountaineering wheels, which can be well-matched with the lighter antenna housing, thus achieving a lightweight lifting device.
