Description

Technical Field

[0001] The invention relates to the technical field of antenna brackets, and in particular provides a corrosion-resistant antenna bracket connected to a steel guardrail. Background Art

[0002] Antenna is a converter that can convert the guided waves propagating on the transmission line into electromagnetic waves propagating in the air, or vice versa. It is a component used to transmit or receive electromagnetic waves in radio equipment. It is widely used in engineering systems such as radio communication, broadcasting, television, and navigation.

[0003] With the rapid development of wireless communication engineering today, antennas are needed near national highways and expressways for signal transmission and reception to meet the communication needs of vehicles during transportation. At present, it is common to build independent signal brackets on the ground outside the highway to install antennas to meet the communication coverage needs of communication operators for highways and surrounding environments. However, the installation workload of building independent signal brackets outside the highway is large, the area occupied is large, and it is not coordinated with the surrounding environment. Since it is fixedly installed outdoors, workers need to climb to adjust the height, which is inconvenient to operate. In addition, the antenna bracket is fixedly installed and cannot be retracted for protection even when not working. In coastal areas, due to the influence of corrosive air, the antenna bracket is prone to corrosion. Summary of the invention

[0004] Based on this, the present invention provides a corrosion-resistant antenna bracket connected to a steel guardrail, which can be stably connected and structurally adapted to the steel guardrails on both sides of the highway, reduce the floor space and construction workload, and realize stable support and flexible lifting and lowering adjustment of the antenna, which can be retracted into a corrosion-resistant protection state when not in use.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a corrosion-resistant antenna bracket connected to a steel guardrail, wherein a left lifting bracket and a right lifting bracket are symmetrically straddled on the steel guardrail and the movable ends extend upward; an antenna mounting seat is arranged directly above the steel guardrail and extends in a horizontal direction, and the movable ends of the left lifting bracket and the right lifting bracket are connected to the bottom of the antenna mounting seat; a protective shell is arranged on the outside of the steel guardrail and has a vertical through space for accommodating the left lifting bracket and the right lifting bracket, and a driving mechanism is drivingly connected to the left lifting bracket and the right lifting bracket, and is configured to drive the movable ends of the left lifting bracket and the right lifting bracket to rise and fall synchronously, thereby driving the antenna mounting seat to be lowered and form an upper end closed structure with the protective shell.

[0006] Furthermore, the protective shell is symmetrically arranged on both sides of the top of the steel guardrail, and the protective shell and the steel guardrail are spaced apart to form a vertical through space. The left lifting bracket and the right lifting bracket are movably arranged in the vertical through space, and the antenna mounting base is lowered and snapped into the upper opening of the protective shell to form an upper end closed structure.

[0008] Furthermore, both sides of the antenna mounting seat in the width direction are connected to the plate-like antenna through hinges arranged in the horizontal direction along the rotating shaft. The antenna mounting seat is provided with a flipping drive mechanism for driving the plate-like antenna to rotate around the hinge. When working, the antenna mounting seat rises, and the flipping drive mechanism drives the plate-like antenna to flip upward to a horizontal state; when not working, the flipping drive mechanism drives the plate-like antenna to flip downward to a vertical state, and the antenna mounting seat is lowered and drives the plate-like antenna into the protective shell.

[0009] Furthermore, the antenna bracket also includes a control unit, which receives working status information of the installed antenna, and controls the antenna bracket to retract into the protective shell when it detects that the antenna is not in a working state, and controls the antenna bracket to extend out of the protective shell when it detects that the antenna is in a working state; and / or, the control unit receives weather condition information transmitted from the outside, and controls the operation of the driving mechanism according to the weather condition information, so as to control the antenna bracket to retract into the protective shell under set weather conditions.

[0010] Furthermore, a bottom horizontal guide rail is arranged along the length direction near the upper end of the steel guardrail, and a bottom left ear seat and a bottom right ear seat are respectively arranged at both ends of the bottom horizontal guide rail. A bottom connecting rod of the left scissors-type connecting rod assembly extends to the lower left direction and is hinged to the bottom left end ear seat, and the other bottom connecting rod extends to the lower right direction and is connected to the left bottom roller. A bottom connecting rod of the right scissors-type connecting rod assembly extends to the lower right direction and is hinged to the bottom right end ear seat, and the other bottom connecting rod extends to the lower left direction and is connected to the right bottom roller. The left bottom roller and the right bottom roller are relatively supported on the bottom horizontal guide rail.

[0013] Compared with the prior art, the technical advantages of the provided corrosion-resistant antenna bracket connected to the steel guardrail are at least reflected in:

[0014] 1. The antenna mounting base is driven to rise and fall by the left and right lifting brackets symmetrically arranged on the steel guardrail, so that the antenna mounting base and the antenna can be flexibly raised and lowered and adjusted and stably supported. A protective shell for accommodating the left and right lifting brackets is arranged on the outside of the steel guardrail. After the antenna mounting base is lowered, it forms an upper end closed structure with the protective shell, which can close and protect the retracted left and right lifting brackets to avoid rain erosion, so that the entire antenna bracket has good corrosion resistance;

[0015] 2. The left lifting bracket and the right lifting bracket respectively include scissor-type connecting rod assemblies arranged in the gap between the protective shell and the two sides of the steel guardrail in the thickness direction, and the scissor-type connecting rod assemblies on both sides of the steel guardrail are connected through the top roller and the bottom roller sliding along the transverse guide rail to establish a stable integrated structure with the steel guardrail, forming a space truss to stably support the antenna mounting seat, which can resist external forces such as strong wind, and occupies a small space outside the steel guardrail, and is integrated with the surrounding environment;

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 10 As shown, the present invention provides a corrosion-resistant antenna bracket connected to a steel guardrail 1, comprising a left lifting bracket 31a and a right lifting bracket 31b, an antenna mounting seat 5, a protective shell 2 and a driving mechanism 4, wherein the left lifting bracket 31a and the right lifting bracket 31b are symmetrically arranged on the steel guardrail 1 and the movable ends extend upward; the antenna mounting seat 5 is arranged directly above the steel guardrail 1 and extends in the horizontal direction, and the movable ends of the left lifting bracket 31a and the right lifting bracket 31b are connected to the bottom of the antenna mounting seat 5; the protective shell 2 is arranged on the outside of the steel guardrail 1 and has a vertical through space for accommodating the left lifting bracket 31a and the right lifting bracket 31b, and the driving mechanism 4 is drivingly connected to the left lifting bracket 31a and the right lifting bracket 31b, and is configured to drive the movable ends of the left lifting bracket 31a and the right lifting bracket 31b to rise and fall synchronously, drive the antenna mounting seat 5 to be lowered and form an upper end closed structure with the protective shell.

[0040] A corrosion-resistant antenna bracket connected to a steel guardrail is provided. A left lifting bracket 31a and a right lifting bracket 31b symmetrically arranged across the steel guardrail 1 are driven synchronously by a driving mechanism to perform lifting and driving adjustment of the antenna mounting seat 5, thereby realizing flexible lifting and lowering adjustment and stable support of the antenna mounting seat 5 and the antenna. The antenna bracket is suitable for installation and use of larger antennas, occupies little space outside the guardrail, is coordinated with the surrounding environment, and is suitable for long-term use in crowded places such as residential areas and streets.

[0041] During the implementation process, the left lifting bracket 31a and the right lifting bracket 31b, the antenna mounting base 5, the protective shell 2 and the driving mechanism 4 are all made of stainless steel components to play a role in corrosion resistance.

[0042] During the implementation, the protective shell 2 is symmetrically arranged on both sides of the top of the steel guardrail 1. The protective shell 2 and the steel guardrail 1 are spaced apart to form a vertical through space. The left lifting bracket 31a and the right lifting bracket 31b are movably arranged in the vertical through space. After the antenna mounting seat 5 is lowered, it is buckled in the upper opening of the protective shell 2 to form an upper end closed structure. Based on the above structure, a protective shell 2 for accommodating the left lifting bracket 31a and the right lifting bracket 31b is arranged outside the steel guardrail 2. After the antenna mounting seat 5 is lowered, it forms an upper end closed structure with the protective shell 2, which can close and protect the retracted left lifting bracket 31a and the right lifting bracket 31b to avoid rain erosion, so that the entire antenna bracket has good corrosion resistance.

[0043] like Fig.11 and Fig.12 As shown, in some embodiments, both sides of the antenna mounting seat 5 in the width direction are connected to the plate antenna 6 through hinges arranged along the horizontal direction of the rotating shaft. The antenna mounting seat 5 is provided with a flipping drive mechanism for driving the plate antenna 6 to rotate around the hinge. When working, the antenna mounting seat 5 is raised, and the flipping drive mechanism drives the plate antenna 6 to flip upward to a horizontal state; when not working, the flipping drive mechanism drives the plate antenna 6 to flip downward to a vertical state, and the antenna mounting seat 5 is lowered and drives the plate antenna 6 to enter the protective shell 2.

[0044] During use, the plate antenna 6 is flipped and connected to both sides of the antenna mounting base 5. When working, the left lifting bracket 31a and the right lifting bracket 31b extend from the protective shell 2 to drive the antenna mounting base 5 to rise, and the plate antenna 6 flips upward to the unfolded state to receive signals; when not working, the plate antenna 6 flips downward to both sides of the left lifting bracket 31a and the right lifting bracket 31b, and the plate antenna is retracted into the protective shell 2 together with the left lifting bracket 31a and the right lifting bracket 31b, and the antenna mounting base 5 and the protective shell 2 form an upper end closed structure, which not only provides corrosion resistance to the lifting bracket and the driving mechanism 4, but also provides corrosion resistance to the plate antenna 6, and effectively resists external destructive behavior, thereby improving the safety of use.

[0045] Furthermore, the antenna bracket also includes a control unit, which receives working status information of the installed antenna, and controls the antenna bracket to retract into the protective shell 2 when it detects that the antenna is not in a working state, and controls the antenna bracket to extend out of the protective shell 2 when it detects that the antenna is in a working state; and / or, the control unit receives weather condition information transmitted from the outside, and controls the drive mechanism 4 to operate according to the weather condition information, so as to control the antenna bracket to retract into the protective shell 2 under set weather conditions.

[0046] In some embodiments, the left lifting bracket 31a and the right lifting bracket 31b respectively include two groups of scissor-type connecting rod assemblies symmetrically arranged on both sides of the thickness direction of the steel guardrail 1 and in the gap between the protective shell, and the top of each group of scissor-type connecting rod assemblies is respectively connected to the outside of the antenna mounting seat 5, and the driving mechanism 4 is connected to each group of scissor-type connecting rods to drive each group of scissor-type connecting rod assemblies to move synchronously. The scissor-type connecting rod assembly has the characteristics of occupying a small space outside the guardrail and a large lifting height. It is arranged on both sides of the rear end direction of the guardrail to form an integrated structure with the steel guardrail 1, and is easy to install and adjust.

[0047] Furthermore, during the implementation process, a bottom horizontal guide rail is arranged along the length direction near the upper end of the steel guardrail 1, and a bottom left ear seat and a bottom right ear seat are respectively arranged at both ends of the bottom horizontal guide rail. A bottom connecting rod of the left scissors-type connecting rod assembly extends to the lower left direction and is hinged to the bottom left end ear seat, and the other bottom connecting rod extends to the lower right direction and is connected to the left bottom roller 32a. A bottom connecting rod of the right scissors-type connecting rod assembly extends to the lower right direction and is hinged to the bottom right end ear seat, and the other bottom connecting rod extends to the lower left direction and is connected to the right bottom roller 32b. The left bottom roller 32a and the right bottom roller 32b are relatively supported on the bottom horizontal guide rail. During implementation, the left bottom roller 32a and the right horizontal roller are respectively provided with wheel grooves adapted to the thickness of the horizontal guide rail, the wheel shaft of the left bottom roller 32a extends out symmetrically at both ends, and a pair of bottom connecting rods symmetrically arranged on both sides of the steel guardrail 1 are respectively connected to the two ends of the wheel shaft of the left bottom roller 32a, and the wheel shaft of the right horizontal roller extends out symmetrically at both ends, and another pair of bottom connecting rods symmetrically arranged on both sides of the steel guardrail 1 are connected to the two ends of the wheel shaft of the right bottom roller 32b.

[0048] Based on the above embodiment, the bottom roller support is on the bottom horizontal guide rail of the steel guardrail 1, and combined with the bottom ear seat, the movement of the bottom of the scissors-type linkage assembly is constrained to improve the stability of the telescopic action, and the bottom roller establishes a bottom lateral connection of the scissors-type linkage assemblies on both sides of the steel guardrail 1, so that the bottom of the scissors-type linkage assemblies on both sides form an integrated structure, which can stably support and lift the antenna mounting base 5.

[0049] In some embodiments, the antenna mounting seat 5 is provided with a top horizontal rail along the length direction, and the top left end ear seat and the top right end ear seat are provided at both ends of the top horizontal rail, respectively. A top link of the left scissor-type linkage assembly extends to the upper left direction and is hinged to the top left end ear seat, and another top link extends to the upper right direction and is connected to the left top roller 36a. A top link of the right scissor-type linkage assembly extends to the upper right direction and is hinged to the top right end ear seat, and another top link extends to the upper left direction and is connected to the right top roller 36b. The left top roller 36a and the right top roller 36b are supported on the top horizontal rail relative to each other. Based on the above embodiment, the top roller is supported on the top horizontal rail of the antenna mounting seat, and the top ear seat is combined to constrain the movement of the top of the scissor-type linkage assembly to improve the stability of the telescopic action, and the top roller establishes a top lateral connection of the scissor-type linkage assembly on both sides of the steel guardrail 1, so that the top of the scissor-type linkage assembly on both sides forms an integrated structure, forming a stable support for the antenna mounting seat 5.

The rotary motor 41 drives the symmetrically arranged left-hand screw and right-hand screw to synchronously adjust the left lifting bracket 31a and the right lifting bracket 31b. The process is stable and balanced, and the driving mechanism 4 is small in size and suitable for use at the bottom of the antenna mounting base 5.

[0051] In some embodiments, the wheel axle of the left bottom roller 32a is also connected to a left auxiliary connecting rod 33a extending to the lower right, and the left end bottom ear seat is connected to the left auxiliary connecting rod 33a in the middle through a left half connecting rod 34a, and a left auxiliary roller 35a is provided at the lower end of the left auxiliary connecting rod 33a, and the left auxiliary roller 35a is supported on the left vertical guide rail below the left end ear seat; the wheel axle of the right bottom roller 32b is also connected to a right auxiliary connecting rod 33b extending to the lower left, and the right end bottom ear seat is connected to the right auxiliary connecting rod 33b in the middle through a right half connecting rod 34b, and a right auxiliary roller 35b is provided at the lower end of the right auxiliary connecting rod 33b, and the right auxiliary roller 35b is supported on the left vertical guide rail below the right end ear seat. Furthermore, the wheel shaft of the left auxiliary roller 35a is symmetrically extended at both ends, and the left auxiliary connecting rods 33a symmetrically arranged on both sides of the steel guardrail 1 are connected to both ends of the wheel shaft of the left auxiliary roller 35a. The wheel shaft of the right auxiliary roller 35b is symmetrically extended at both ends, and the right auxiliary connecting rods 33b symmetrically arranged on both sides of the steel guardrail 1 are connected to both ends of the wheel shaft of the right auxiliary roller 35b. Through the arrangement of the auxiliary connecting rods and auxiliary rollers, not only the bottom vertical support of the left lifting bracket 31a and the right lifting bracket 31b is improved, but also a lateral connection between the two is established, thereby improving the structural strength.

[0052] Based on the above embodiments, the left lifting bracket 31a and the right lifting bracket 31b respectively include scissor-type linkage assemblies arranged in the gap between the protective shell 2 and the two sides of the steel guardrail 1 in the thickness direction, and the scissor-type linkage assemblies on both sides of the steel guardrail 1 are supported and connected with the top rollers, bottom rollers and auxiliary rollers that slide along the transverse guide rails to establish a stable integrated structure with the steel guardrail 1, forming a spatial truss to stably support the antenna mounting seat 5, which can withstand external forces such as strong winds, and occupies a small space outside the steel guardrail 1, integrating with the surrounding environment.
