Description
Technical Field
[0001] This invention relates to the field of machine bases or supports for instruments or articles thereof, specifically a mounting bracket for a traffic display screen. Background Technology
[0002] A display screen mounting bracket is a device that restricts the fixation or displacement of a display screen. It is a type of support. Traffic warning information display screens are used to provide road condition information to vehicles by setting up electronic display boards on roads to display road conditions. They need to be mounted on the surface of a support for observation via a mounting bracket.
[0003] During road construction or maintenance, it is necessary to place warning signs to provide traffic information alerts for the construction section. In existing technologies, triangular brackets are generally used to place the signs on the ground to alert approaching vehicles. However, this method cannot allow drivers far away to observe road information in advance and change lanes in time, thus causing traffic congestion. Another method is to install display screens at higher positions on streetlights or utility poles on both sides of the road to more effectively alert drivers. However, this method requires construction workers to use ladders or other climbing equipment to install the display screens. This not only poses certain safety risks to construction workers but also affects the normal driving of the lanes below. Based on this, this invention applies for the design of a mounting frame for a traffic display screen. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. Through the set clamping structure, climbing structure, and fixing structure, by opening the folding rod and covering the outside of the street light pole or utility pole, and making the friction rollers fit against the outer surface of the street light pole or utility pole, the folding rod is reset and fixed by tightening the fastening handwheel. At this time, driven by the electric telescopic rod, the telescopic rod drives the mounting block forward, and the straight groove rod moves on the outer surface of the limit rod. The first rotating rod can move in the straight groove, thereby moving the entire climbing structure forward, so that the two climbing wheels fit together and squeeze the column. At this time, driven by the dual-head servo motor, the second bevel gear meshes with the first bevel gear, thereby driving the first rotating rod to rotate at high speed. Because the climbing wheels fit against the street light pole or utility pole, the device moves forward. The friction on the pole surface enables the entire device to climb the pole. After the device moves to the appropriate position, the electric telescopic rod drives the entire climbing structure to move backward. At this time, the first rotating rod stops rotating, and the dual-head servo motor drives the third bevel gear to move backward quickly and mesh with the second pulley. The second pulley rotates and drives the bidirectional screw to rotate through the linkage belt. Due to the limiting of the transverse groove rod, the two threaded blocks can move simultaneously to the middle position of the bidirectional screw, thereby allowing the two semi-circular hoops to tightly clamp the column, thus achieving the positioning of the device. This structure can flexibly control the fixing and climbing of the device through the clamping structure and the climbing structure. It is suitable for early warning of traffic roads before construction, and is simple to assemble and disassemble, requiring no manual high-altitude work.
[0017] 2. Through the shock-absorbing structure, after the device is used, when the dual-head servo motor reverses to disengage the two semi-circular rings from the streetlight pole and utility pole, the two climbing wheels reverse to drive the device to fall rapidly from their surface. When it falls to the ground, the rubber airbag first contacts the ground to absorb part of the impact. After the two dampers are impacted, the upper part of the device presses down on the mounting plate. Due to the hinge between the hinge rod and the second hinge seat, when the mounting plate is pressed down, the two hinge rods drive the two sliding blocks to move to both sides, which can compress the tough spring and thus buffer the remaining impact, preventing the device from being damaged by impact, improving the safety and service life of the device.

[0029] 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 some embodiments of the present invention, and not all embodiments. 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.
[0030] Please see Figure 4 , Figure 5 , Figure 7 and Figure 8 A mounting bracket for a traffic display screen includes: a protective housing 1, with a clamping structure 4 inside the protective housing 1 for fixing a street light pole or utility pole. The clamping structure 4 includes a horizontal groove rod 41, a back plate 9 fixedly installed at the bottom of the horizontal groove rod 41, a back groove 12 opened inside the back plate 9, side plates 6 fixedly installed on both sides of the back plate 9, and a climbing structure 8 for climbing the pole between the two side plates 6; the two sides of the horizontal groove rod 41 are fixedly connected to the protective housing 1, and a double-acting screw 42 is rotatably installed inside the horizontal groove rod 41. Threaded blocks 43 are threaded on both sides of the outer surface of the double-acting screw 42, and the two threaded blocks 43 are symmetrically installed. An extension rod 44 is fixedly installed on one side of the outer surface of the two threaded blocks 43, and a semi-circular hoop 45 is fixedly installed on one side of the two extension rods 44. A first pulley 46 is fixedly installed in the middle of the outer surface of 42; the climbing pole structure 8 includes a mounting block 81, a first rotating rod 82 is rotatably installed inside the mounting block 81, climbing pole wheels 83 are fixedly installed on both sides of the outer surface of the first rotating rod 82, a first bevel gear 84 is fixedly installed on the right outer surface of the first rotating rod 82, a limit rod 86 is fixedly installed between the inner wall of the back plate 9, a straight groove rod 85 is snapped onto the outer surface of the limit rod 86, a fixing ring 87 is fixedly installed at one end of the straight groove rod 85, a dual-head servo motor 88 is fixedly installed inside the fixing ring 87, a second bevel gear 89 is fixedly installed on the lower output shaft of the dual-head servo motor 88, a third bevel gear 810 is fixedly installed on the upper output shaft of the dual-head servo motor 88, and the second bevel gear 89 meshes with the first bevel gear 84.
[0031] Please see Figure 4 Figure 7 and Figure 8Two support seats 16 are fixedly installed on one side of the back plate 9. A second rotating rod 17 is rotatably installed between the two support seats 16. A second pulley 18 is fixedly installed in the middle of the outer surface of the second rotating rod 17. A linkage belt 13 is sleeved between the second pulley 18 and the first pulley 46. A fourth bevel gear 19 is fixedly installed on the right side of the outer surface of the second rotating rod 17. The fourth bevel gear 19 meshes with the third bevel gear 810. Straight slots 15 are opened inside the two side plates 6. The two ends of the first rotating rod 82 are movably sleeved with the straight slots 15 through bearings, so that the first rotating rod 82 can rotate and move horizontally in the straight slots 15. Two side support rods 10 are fixedly installed on one side of the outer surface of the back plate 9. An electric telescopic rod 11 is fixedly installed between the two side support rods 10. One end of the telescopic rod of the electric telescopic rod 11 is fixedly connected to the mounting block 81.
[0032] It should be further explained that: the second rotating rod 17 allows for selective connection between the second pulley 18 and the third bevel gear 810. When the electric telescopic rod 11 (model: XDHA12-100024V) pushes the mounting block 81 forward, the dual-head servo motor 88 drives the third bevel gear 810 to move forward as well. At this time, the third bevel gear 810 is not connected to the second pulley 18. When it is necessary to clamp the structure 4 to position and lock the column 2, the electric telescopic rod 11 drives the mounting block 81 to return to the position of the second pulley 18. At this time, due to the internal reduction structure (servo) of the dual-head servo motor 88... During operation, the motor typically works in conjunction with a speed reducer to slow down the high-speed rotation of the motor output shaft (the speed reducer is a current technology and is not described in detail here). Therefore, the third bevel gear 810 will not rotate when it moves to the position of the fourth bevel gear 19 to prevent gear breakage (because the dual-head servo motor 88 may briefly pause during movement, causing the device to slide downwards, the device should be climbed at a height slightly higher than the expected height). This ensures that when the dual-head servo motor 88 stops moving, the device will fall to the vicinity of the expected position. Similarly, the dual-head servo motor 88 will brake and stop when it disengages from the first bevel gear 84. When the dual-head servo motor 88 disengages from the first bevel gear 84, the first rotating rod 82 will not stop rotating immediately, and the two climbing wheels 83 will not stop rotating immediately after losing power.
[0033] Please see Figure 6The two side plates 6 are equipped with fixing structures 14 for initially fixing the device to streetlights or utility poles. The fixing structure 14 includes a fixing pin 141, which is located in the inner groove of the left side plate 6. A folding rod 142 is hinged to the outer surface of the fixing pin 141. A friction roller 143 is rotatably mounted on one side of the outer surface of the folding rod 142. The friction roller 143 has a groove on its surface and a rounded corner on its outer surface. A fastening handwheel 144 is threadedly installed in the groove of the right side plate 6. The fastening handwheel 144 is threadedly connected to one end of the folding rod 142.
[0034] It should be further explained that when the device is initially installed at the bottom of the street light pole or utility pole, the device is moved until the friction roller 143 is in contact with the surface of the column 2 after the folding rod 142 is opened and wrapped around the outside of the street light pole or utility pole. The fastening handwheel 144 is then inserted into the side plate 6 and tightened to fix it. At this time, the initial fixation of the device is completed. During the descent, during the stop interval of the dual-head servo motor 88, since the device has more structure on the right side and is heavier, the whole device tilts to the right side when it stops descent. At this time, the weight of the whole device pulls the friction roller 143 and applies pressure to the street light pole or utility pole. At the same time, there is friction between the surface of the friction roller 143 and the device, so the descent speed is not high and the descent distance is controllable.
[0035] Please see Figure 9 and Figure 10 Two side plates 6 are fixedly mounted at their bottoms with shock-absorbing structures 7 to absorb the impact force when the device falls. The two shock-absorbing structures 7 include two mounting slots 71 and two first hinge seats 74. The tops of the two first hinge seats 74 are fixedly connected to the side plates 6. Dampers 73 are fixedly mounted on both sides of the top of the mounting slots 71, and the tops of the two dampers 73 are fixedly connected to the bottom of the side plates 6. The mounting slots 71 have grooves inside, and sliding rods 77 are fixedly mounted therein. Rubber airbags 72 are fixedly mounted at the bottom of the mounting slots 71. Hinge rods 75 are hingedly mounted inside the two first hinge seats 74. Second hinge seats 76 are hingedly mounted at one bottom end of the two hinge rods 75. Resilient springs 79 are fixedly mounted on both sides of the outer surface of the sliding rods 77. Sliding blocks 78 are fixedly mounted at one end of the two resilient springs 79. The two sliding blocks 78 are slidably connected to the sliding rods 77, and each of the two sliding blocks 78 is fixedly connected to its corresponding second hinge seat 76.
[0036] It should be further explained that the two rubber airbags 72 are made of three layers of rubber pads, which have strong wear resistance and impact resistance. They can effectively resist the friction generated when the weight of the device contacts the ground when it falls, so as to prevent damage or cracks on the surface and thus prevent the rubber airbags 72 from rupturing. The rubber airbags 72 are sealed and filled with 75% gas to ensure that there is enough elasticity and rebound space inside the rubber airbags 72 when the device contacts the ground. When the device contacts the ground, the rubber airbags 72 first contact the ground and absorb part of the impact. After the two dampers 73 are impacted, they cause the upper part of the device to press down on the mounting plate 71. Due to the hinge of the hinge rod 75 and the second hinge seat 76, when the mounting plate 71 is pressed down, the two hinge rods 75 drive the two sliding blocks 78 to move to both sides, thereby squeezing the toughness springs 79, which can buffer the remaining impact and prevent the device from being damaged by impact. The two toughness springs 79 on the outer surface of the sliding rod 77 are rigid springs with high toughness to ensure that they can buffer the impact generated by the device falling.
[0037] Please see Figure 1 and Figure 2 A fixing bracket 5 is fixedly installed on one side of the outer surface of the horizontal groove rod 41. The fixing bracket 5 has multiple slots for fixing inside. A warning display screen 3 is fixedly installed on one side of the outer surface of the fixing bracket 5 by fastening bolts. A column 2 is set between the two semi-circular hoop rings 45.
[0038] It should be further explained that: Streetlights or utility poles of general diameter are approximately 20cm. When climbing such poles, the control device can ascend to any height on the pole. For some tapered poles, the control device can ascend to 5-8 meters above the main body. When installing the warning display screen 3, the screen is connected to the mounting brackets 5 on both sides using fastening bolts, thus completing the connection of the warning display screen 3.
[0039] Working principle: First, the warning display screen 3 is connected to the fixing frame 5 by fastening bolts. Then, the device is moved to the vicinity of the column 2, the folding rod 142 is opened and the device is wrapped around the column 2, and the friction roller 143 is attached to one side of the outer surface of the column 2. At this time, the folding rod 142 is reset and the fastening handwheel 144 is inserted into the side plate 6 and tightened to fix it. At this time, the initial fixation of the device is completed. Then, driven by the electric telescopic rod 11, its telescopic rod drives the mounting block 81 to move forward. At the same time, the straight groove rod 85 moves on the outer surface of the limiting rod 86, and the first rotating rod 82 can move in the straight groove 15. This allows the entire climbing pole structure 8 to move forward, so that the two climbing pole wheels 83 are in contact with the column. When the extrusion column 2 is combined, the second bevel gear 89 is driven by the dual-head servo motor 88 to mesh with the first bevel gear 84, thereby driving the first rotating rod 82 to rotate at high speed. Due to the friction between the climbing wheel 83 and the surface of the column 2, the entire device can climb the rod. After the device moves to the appropriate position, the climbing structure 8 is moved backward by the electric telescopic rod 11. At this time, the first rotating rod 82 stops rotating, and the dual-head servo motor 88 drives the third bevel gear 810 to move backward quickly and mesh with the second pulley 18. At this time, the second pulley 18 rotates and drives the bidirectional lead screw 42 to rotate through the linkage belt 13. Due to the limiting of the transverse groove rod 41, the two threaded blocks 43 can simultaneously move towards the bidirectional lead screw 42. 2. The middle position is moved, so that the two semi-circular rings 45 can tightly clamp the outer surface of the column 2, thereby achieving the positioning of the device. At this time, the driver on this road can receive the specific information of the road construction ahead through the warning display screen 3, so as to change lanes according to the implementation situation. At this time, the construction personnel can start road construction and other work. After the construction is completed, the double-head servo motor 88 is driven to reverse. At this time, when the two semi-circular rings 45 on both sides are disengaged from the street light pole and the utility pole, the two climbing wheels 83 are disengaged from the column. At the same time, during the interval when the double-head servo motor 88 stops rotating, because the device has more structure on the right side and is heavier, the whole device tilts to the right side when it stops rotating and descends. At this time, the weight of the whole device pulls the friction. The rubbing roller 143 applies pressure to the streetlight pole or utility pole, and the surface of the rubbing roller 143 rubs against it, so the descent speed is not large. Therefore, the device can be driven to fall slowly from the surface of the column. When it falls to the ground, the rubber airbag 72 first contacts the ground and absorbs part of the impact. After the two dampers 73 are impacted, the upper part of the device presses down on the mounting slot plate 71. Due to the hinge of the hinge rod 75 and the second hinge seat 76, when the mounting slot plate 71 is pressed down, the two hinge rods 75 drive the two sliding blocks 78 to move to both sides, thereby squeezing the tough spring 79 and buffering the remaining impact to prevent the device from being damaged by the impact. After the device falls safely, the device can be removed from the column 2 for recycling.
[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
