Description

Technical Field

[0001] This utility model relates to the field of traffic guidance screen technology, and in particular to a traffic LED guidance screen that is easy to maintain. Background Technology

[0002] In the current era of rapid development of intelligent transportation systems, LED guidance screens for traffic use are playing an increasingly important role as key information dissemination and traffic guidance equipment. Based on a matrix of high-brightness LEDs, these screens possess excellent visual performance, clearly and prominently displaying various traffic information under different lighting conditions, such as bright daylight or dim nighttime conditions. Through advanced control technology and communication modules, LED guidance screens can receive and process instructions from the traffic management center in real time, dynamically displaying road condition information, traffic control notices, road construction warnings ahead, parking guidance, and other content. This provides drivers with timely and accurate traffic guidance, helping to alleviate traffic congestion, improve road efficiency, and ensure safe and orderly traffic operation, making them an indispensable intelligent facility in modern traffic management systems.

[0003] Patent document CN213978695U discloses a road LED guidance screen, including a support column. A vertically oriented cavity is formed at the center of the support column, and a vertically oriented rotating shaft is rotatably connected to the center of the cavity. A fourth gear is fixedly connected to the top of the rotating shaft surface, and a first gear is fixedly connected to the bottom of the rotating shaft surface. In this invention, by setting up a rotating rod, annular groove, wire rope, slider, connecting block, and housing, the rotating rod allows the wire rope wound in the annular groove to move up and down within the groove through its fixed connection with the slider. This, in turn, moves the connecting block and housing up and down, facilitating height adjustment of the housing and thus simplifying the installation and maintenance of the guidance screen.

[0004] As in the prior art of the aforementioned patent, the aforementioned guidance screen can be raised and lowered to the lowest position to facilitate maintenance during the inspection process. However, guidance screens are generally set on both sides of the road, directly above the road. During maintenance, the guidance screen will obstruct the road, requiring the placement of a triangular sign in front of the road. This increases the risk during maintenance and also increases the pressure of traffic congestion. Utility Model Content

[0005] The purpose of this invention is to provide a traffic LED guidance screen that is easy to maintain, so as to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a traffic LED guidance screen that is easy to maintain, comprising a support column, a rotating frame rotatably mounted at the top of the support column, a sliding groove fixedly mounted on one side of the rotating frame, two sliders slidably mounted inside the sliding groove, a screw rotatably mounted inside the sliding groove, the screw being threadedly connected to the two sliders, an LED guidance screen body fixedly mounted at the bottom of the two sliders, a fixed cylinder mounted on the support column, and a drive transmission assembly for driving the rotating frame and the screw to rotate inside the fixed cylinder.

[0007] As a further description of the above technical solution: multiple climbing frames are fixedly installed on the support column.

[0008] As a further description of the above technical solution: the main body of the LED guidance screen is provided with an LED guidance screen back plate, and a maintenance platform is fixedly installed on the LED guidance screen back plate.

[0010] As a further description of the above technical solution: the drive transmission assembly also includes a geared disc fixedly mounted on the support column. The geared disc is disposed inside the fixed cylinder. One end of the screw passes through the rotating frame and the fixed cylinder and is fixedly mounted with a gear. The gear meshes with the tooth groove at the top of the geared disc. The screw is rotatably connected to the rotating frame.

[0011] As a further description of the above technical solution: an arc-shaped through groove is provided on the fixed cylinder, and the arc-shaped through groove is provided along the rotation trajectory of the screw around the gear disk.

[0012] This invention provides a traffic LED guidance screen that is easy to maintain. It offers the following advantages: When maintenance of the LED guidance screen body is required, the rotating frame can be rotated by activating the drive transmission assembly. Simultaneously, the rotating frame drives the screw to rotate, causing two sliders to slide towards the support column. This moves the LED guidance screen body closer to the support column. Furthermore, the rotating frame can rotate the LED guidance screen body, along with the sliding groove, to the side away from the road, i.e., towards the sidewalk. Workers can then climb the scaffolding to the top of the support column and access the maintenance platform to inspect the LED guidance screen body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5A traffic LED guidance screen that is easy to maintain includes a support column 1. A rotating frame 4 is rotatably mounted on the top of the support column 1. A sliding groove 8 is fixedly mounted on one side of the rotating frame 4. Two sliders 10 are slidably installed inside the sliding groove 8. A screw 9 is rotatably mounted inside the sliding groove 8 and threadedly connected to the two sliders 10. An LED guidance screen body 12 is fixedly mounted on the bottom end of the two sliders 10. A fixing cylinder 5 is provided on the support column 1. A drive transmission assembly for driving the rotating frame 4 and the screw 9 to rotate is provided inside the fixing cylinder 5. When it is necessary to maintain the LED guidance screen... When the main body 12 is being maintained, the rotating frame 4 can be rotated by activating the drive transmission assembly. The rotation of the rotating frame 4 can drive the screw 9 to rotate. The rotation of the screw 9 can drive the two sliders 10 to slide towards the support column 1, thereby moving the LED guidance screen main body 12 to the side closer to the support column 1. The rotating frame 4 can also rotate the LED guidance screen main body 12, together with the sliding groove 8, to the side away from the road, i.e., the sidewalk. Construction workers can climb to the top of the support column 1 using the climbing frame 2 and then enter the maintenance platform 14 to inspect the LED guidance screen main body 12.

[0024] As a preferred technical solution in this embodiment, multiple climbing frames 2 are fixedly installed on the support column 1; the climbing frames 2 enable maintenance personnel to climb and enter the maintenance platform 14 for maintenance.

[0025] As a preferred technical solution in this embodiment, an LED guidance screen back plate 13 is provided on the main body 12 of the LED guidance screen, and a maintenance platform 14 is fixedly installed on the LED guidance screen back plate 13; maintenance personnel can directly enter the maintenance platform 14 to carry out maintenance, which increases maintenance efficiency.

[0026] As a preferred technical solution of this embodiment, the drive transmission assembly includes a self-locking motor 3 disposed inside the fixed cylinder 5. The top end of the support column 1 passes through the bottom end of the fixed cylinder 5 and is fixedly connected to the self-locking motor 3. The output end of the self-locking motor 3 is connected to the rotating frame 4 in a transmission manner. The self-locking motor 3 can drive the rotating frame 4 to rotate. The rotating frame 4 can drive the sliding groove 8 and the LED guidance screen body 12 to rotate, so that the LED guidance screen body 12 rotates to the top of the side away from the road.

[0027] As a preferred technical solution in this embodiment, the drive transmission assembly further includes a geared disc 6 fixedly mounted on the support column 1. The geared disc 6 is disposed inside the fixed cylinder 5. One end of the screw 9 passes through the rotating frame 4 and the fixed cylinder 5 and is fixedly mounted with a gear 7. The gear 7 meshes with the tooth groove at the top of the geared disc 6. The screw 9 is rotatably connected to the rotating frame 4. During the rotation of the rotating frame 4, it can drive the gear 7 at one end of the screw 9 to rotate around the axis of the geared disc 6. Under the action of the geared disc 6, the gear 7 can drive the screw 9 to rotate, thereby realizing the rotation of the screw 9. The self-locking motor 3 is existing technology. Its function is that the output shaft of the self-locking motor 3 is locked in the absence of power and will not rotate, thereby ensuring the stability of the rotating frame 4 and preventing the rotating frame 4 from rotating due to external influences.

[0028] As a preferred technical solution in this embodiment, the fixed cylinder 5 is provided with an arc-shaped through groove, which is opened along the rotation trajectory of the screw 9 around the gear disk 6; when the rotating frame 4 drives the screw 9 to rotate, the screw 9 rotates around the axis of the fixed cylinder 5, and the opening of the arc-shaped through groove enables the screw 9 to rotate smoothly.

[0029] It is worth mentioning that the connection between the aforementioned maintenance platform 14, screw 9, slider 10, rotating frame 4, and sliding groove 8 and the support column 1 is relatively tight, and the materials used are all high-strength steel materials, so there will be no breakage.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
