Description

Technical Field

[0001] The present invention relates to the technical field of advertisement delivery, and in particular to an advertisement delivery device based on e-commerce. Background Art

[0002] Commercial advertising is an advertisement that delivers product information, promotional information, and guides the public to generate consumer desires and behaviors. It is a form of advertising produced and released to promote specific products, services, or brands. This type of advertising aims to attract consumers' attention and encourage them to buy or use the promoted products or services. Commercial advertising is usually disseminated through multiple channels, such as television, radio, the Internet, print media, etc., to achieve the purpose of promotion and marketing.

[0003] In order to attract more consumers, commercial advertisements mostly use electronic display screens or printed billboards that can release new information at any time. However, no matter whether it is an electronic display screen or a printed billboard, during installation, a lifting machine and a lifting wire rope are usually used to lift the electronic display screen or printed billboard to a high altitude for installation. The wind is strong at high altitudes. During the process of lifting and moving the billboard, it is easy to shake when it is lifted by the lifting wire rope, which affects the stability of the billboard and increases safety risks. In addition, the lifting machine for advertising has at least 4 long lifting wire ropes. Due to the erosion of the lifting wire rope by wind and rain, and the effect of long-term stress, the molecular structure inside the lifting wire rope will gradually adjust, making the tightness of the four lifting wire ropes uneven. When the billboard is lifted, it is easy for each lifting wire rope to be unevenly distributed, causing the billboard to tilt during lifting, and at the same time affecting the service life of the overall lifting wire rope. In order to solve the shortcomings of the prior art, we propose an advertising placement device based on e-commerce. Summary of the invention

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] The portal frame 1 comprises a supporting beam frame 11 , a walking mechanism 12 is arranged on both sides of the bottom of the supporting beam frame 11 , and a movable slide rail 13 is arranged on both sides of the top of the supporting beam frame 11 .

[0037] like Fig. 9 As shown, the lifting device 3 includes a top plate 31, and rotating wheels 32 are rotatably installed at the four corners of the top of the top plate 31. The wire rope 49 is movably sleeved on the outer surface of the rotating wheel 32. A top frame 33 is fixedly installed on the top of the top plate 31, and embedded rods 34 are fixedly installed on both sides of the top of the top frame 33. A billboard hanger 35 is arranged at the bottom of the top plate 31.

[0038] By setting the embedded rod 34, after the billboard hanger 35 fixes the billboard, the lifting sling 3 rises, and the embedded rod 34 is inserted into the bottom of the movable inner rod 2112, so that the lifting mechanism 2 and the lifting sling 3 are relatively fixed, avoiding the lifting sling 3 from being affected by wind or movement of the lifting device, causing the billboard to shake during transportation, affecting the stability of the billboard.

[0039] like Figure 3-4As shown, the lifting mechanism 2 includes a sliding seat 21, and two groups of connecting grooves 26 are opened inside the left and right ends of the sliding seat 21. Two groups of support frames are fixedly installed on the left side of the top of the sliding seat 21. The insides of the two groups of support frames are rotatably installed with a cable drum 22. The side of the support frame is fixedly connected to a winding motor 23. One end of the cable drum 22 is fixedly connected to the output end of the winding motor 23. Two groups of support rollers 25 are arranged on the right side of the sliding seat 21. The two groups of cable drums 22 and the two groups of support rollers 25 are respectively located above the connecting grooves 26 on the left and right sides of the sliding seat 21. The outer surface of the cable drum 22 is connected to the steel wire. The two ends of the rope 49 are wound and connected, and the left and right sides of the top of the sliding seat 21 are fixedly installed with walking motors 27, and the left and right sides of the bottom of the sliding seat 21 are rotatably installed with moving rollers 28. The moving rollers 28 are connected to the output ends of the walking motors 27 through transmission belts. The moving rollers 28 are rollingly installed inside the moving slide rail 13. The sliding seat 21 is slidably installed on the top of the supporting beam 11. A reinforcing support frame 29 is fixedly installed in the middle of the bottom of the sliding seat 21. The interior of the reinforcing support frame 29 is fixedly sleeved with a fixed sleeve 210, and the bottom of the fixed sleeve 210 is movably sleeved with a telescopic inner frame 211.

[0040] Two steel wire ropes 49 are wound around the outer surface of each cable drum 22. One steel wire rope 49 passes through the connecting groove 26 at the bottom of the cable drum 22, passes through the adjusting device 4 at the bottom of the cable drum 22, and is sleeved on the outer surface of the rotating wheel 32 at the left end of the top plate 31. The other steel wire rope 49 passes through the supporting roller 25 and passes through the connecting groove 26 at the right end of the sliding seat 21, and is movably sleeved on the outer surface of the rotating wheel 32 at the right end of the top plate 31. When the winding motors 23 at both ends synchronously control the winding and unwinding of the cable drum 22, the surrounding steel wire ropes 49 are synchronously wound or unwound, so that the lifting sling 3 rises or falls.

[0041] In this embodiment, when the cable drum 22 unwinds the wire rope 49, the lifting sling 3 is lowered, and the telescopic inner frame 211 is affected by gravity, and extends as the lifting sling 3 descends, and contracts as the lifting sling 3 rises. When the telescopic inner frame 211 extends out of the fixed sleeve 210 as the lifting sling 3 descends, the upper end of the wire rope 49 is limited by the fixed sleeve 210 and the telescopic inner frame 211 to prevent the wire rope 49 from being suspended in the air for too long during the lifting process, causing the wire rope 49 to shake greatly during the movement of the gantry 1 or due to the influence of wind, thereby affecting the stability of the billboard during the lifting process.

[0042] like Fig.10As shown, the telescopic inner frame 211 includes a connecting plate 2111, and both ends of the top of the connecting plate 2111 are fixedly connected with movable inner rods 2112, and the upper ends of the movable inner rods 2112 at both ends are provided with movable cavities 2113, and the interior of the movable cavity 2113 is movably sleeved with a sliding block 2114, and the bottom of the sliding block 2114 is fixedly installed with a guide rope 2115, and the bottom of the guide rope 2115 is fixedly connected to the top of the embedded rod 34, the bottom of the movable inner rod 2112 is movably sleeved on the outer surface of the embedded rod 34, and the top of the movable inner rod 2112 is movably sleeved on the inside of the fixed sleeve 210, and the outer surface of the upper end of the guide rope 2115 is movably sleeved with a return spring 2116, and the return spring 2116 is located on the sliding block 2114 and the bottom surface of the movable cavity 2113.

[0043] By setting the return spring 2116, when the lifting sling 3 descends, the embedded rod 34 detaches from the bottom of the movable inner rod 2112. At this time, the guide rope 2115 is affected by the descending of the embedded rod 34, moves downward, and pulls the sliding block 2114 to press on the top of the return spring 2116. The return spring 2116 is compressed. When the lifting sling 3 rises, the return spring 2116 will push the sliding block 2114 to rise inside the movable cavity 2113 through the reaction force, and guide the embedded rod 34 to facilitate the embedded rod 34 to be inserted into the bottom of the movable inner rod 2112, thereby avoiding the situation that after the lifting sling 3 is descended, the embedded rod 34 is not easy to be inserted into the bottom of the movable inner rod 2112 due to the shaking of the lifting sling 3.

[0044] Embodiment 2, as Figure 1 - Figure 6 As shown, an advertising delivery device based on e-commerce is shown, the adjusting device 4 includes a fixed column 41, the outer surface of the upper end of the fixed column 41 is fixedly sleeved with a transmission gear 42, the bottom of the fixed column 41 is fixedly installed with a fixed frame 45, both sides of the fixed column 41 are fixedly installed with auxiliary frames 43, the top of the auxiliary frame 43 is rotatably installed with a hydraulic adjustment rod 44, both ends of the bottom of the fixed frame 45 are rotatably installed with a rotating rod 46, the outer surface of the lower end of the rotating rod 46 is rotatably installed with a connecting frame 47, the top of the connecting frame 47 is fixedly connected to the bottom of the hydraulic adjustment rod 44, the lower end of the rotating rod 46 is rotatably installed with a steering wheel 411, the lower end of the rotating rod 46 is located between the steering wheel 411 and the connecting frame 47 and is fixedly connected with an anti-falling device 410, and both sides of the bottom of the fixed frame 45 are fixedly connected with guide components 48.

[0045] In this embodiment, the hydraulic adjustment rod 44 is contracted to make the rotating rod 46 rotate on the side of the fixed frame 45, and the steering wheel 411 rises at one end of the wire rope 49 to adjust the position of the wire rope 49 and then the length of the wire rope 49. When the lifting sling 3 is hoisted, each wire rope 49 is kept in a taut and stretched state, thereby keeping the load distribution of each wire rope 49 uniform and improving the service life of the entire wire rope 49.

[0046] like Figure 6 As shown, a steel wire rope 49 is movably sleeved inside the fixing frame 45 and the fixing column 41 . The steel wire rope 49 is connected to the lifting sling 3 . The steel wire rope 49 is movably sleeved inside the anti-falling device 410 .

[0047] like Figure 4 - Figure 5 As shown, four groups of base frames 212 are fixedly installed at the bottom of the sliding seat 21, and the four groups of base frames 212 are respectively located below the connecting grooves 26 on the left and right sides. A bottom support frame 213 is fixedly installed at the bottom of the base frame 212, and a reversing motor 214 is fixedly installed on one side inside the bottom support frame 213. A driving gear 215 is fixedly installed on the output end of the reversing motor 214. The driving gear 215 is rotatably installed at one end of the bottom of the bottom support frame 213, and the top of the fixed column 41 is rotatably installed inside the bottom support frame 213, and the outer surface of the transmission gear 42 is meshed with the outer surface of the driving gear 215. An indicator light 216 is provided on one side of the bottom of the base frame 212.

[0048] By using the reversing motor 214, the driving gear 215 can be controlled to rotate, so that the wire ropes 49 at both ends of the steering wheel 411 can be automatically adjusted according to the distribution direction of the rotating wheel 32, so that the lifting device can adapt to lifting equipment 3 of different models and sizes.

[0049] Embodiment three, as Figure 1 - Figure 8 As shown, an advertising delivery device based on e-commerce is shown, the guide component 48 includes a guide frame 481, a fixed plate 483 is fixedly installed in the middle of the guide frame 481, movable grooves 482 are opened on both sides of the lower end of the guide frame 481, and a fixed shaft 484 is movably sleeved inside the movable groove 482. The outer surfaces of both ends of the fixed shaft 484 are rotatably installed with limit frames 487, and the tops of the limit frames 487 at both ends are fixedly installed with top plates 485. The middle parts of the limit frames 487 at both ends are fixedly installed with pressing blocks, the top plates 485 and the pressing blocks are respectively located at the upper and lower sides of the fixed plate 483, and the limit frames 487 are movably sleeved inside the fixed plate 483. A pressure sensor 488 is fixedly installed at the bottom of the fixed plate 483, an extrusion spring 489 is arranged between the pressing block and the fixed plate 483, and the pressing block is movably installed at the bottom of the pressure sensor 488. A limit wheel 486 is rotatably installed on the outer surface of the fixed shaft 484, and the limit wheel 486 is located between the limit frames 487 at both ends.

[0050] The pressure sensor 488 can be used to monitor the changes in the force on the wire rope 49 around the rotating wheel 32. When the force on the wire rope 49 at one place gradually decreases, it means that the wire rope 49 at that place is loose. The pressure sensor 488 controls the corresponding adjusting device 4 to work, so that the hydraulic adjusting rod 44 contracts, and the hydraulic adjusting rod 44 pulls the corresponding connecting frame 47 to move upward, and the rotating rod 46 unfolds, so that the wire rope 49 is in a taut state, and then the pressure values ​​of the four pressure sensors 488 at the bottom of the sliding seat 21 are at the same value, so that the four corners of the lifting sling 3 are stretched evenly, and the lifting sling 3 is kept level when stretched, so as to avoid the billboard from tilting during the lifting process. At the same time, the four wire ropes 49 at the top of the lifting sling 3 are evenly stressed, thereby improving the service life of the overall wire rope 49.

[0051] The guide frame 481 is fixedly mounted at both ends of the bottom of the fixed frame 45 , the wire rope 49 is movably sleeved on the bottom of the limiting wheel 486 , and the pressure sensor 488 is electrically connected to the indicator light 216 and the hydraulic adjustment rod 44 respectively.

[0052] like Figure 8 As shown, the anti-falling device 410 includes an anti-falling frame 4101, an anti-falling motor 4102 is fixedly installed on one side of the anti-falling frame 4101, the anti-falling motor 4102 is electrically connected to the pressure sensor 488, a cavity is provided on the side of the anti-falling frame 4101 away from the anti-falling motor 4102, movable holes 4103 are provided on both sides of the cavity of the anti-falling frame 4101, an output end of the anti-falling motor 4102 is fixedly connected to a rotating tube 4104, locking blocks 4106 are fixedly connected on both sides of the rotating tube 4104, and locking teeth 4107 are provided on the sides of the locking blocks 4106 facing each other.

[0053] Among them, a rope groove 4105 is opened inside the rotating tube 4104, the rope groove 4105 is movably connected to the outer surface of the wire rope 49, the movable hole 4103 is movably connected to the outer surface of the wire rope 49, the anti-falling frame 4101 is fixedly installed at the lower end of the rotating rod 46 and is located above the steering wheel 411, and the wire rope 49 passes through the inside of the anti-falling device 410 and is movably connected to the top of the steering wheel 411.

[0054] By setting a pressing block in the middle of the limit frame 487, the bottom of the pressure sensor 488 will be pressed, so that the pressure sensor 488 always feels the pressure. When the pressure sensor 488 at a certain place suddenly cannot sense the corresponding pressure after sensing the pressure, the indicator light 216 flashes through an electrical signal, so that the operator can quickly understand the lifting situation and quickly determine whether the wire rope 49 is broken and falls off at a specific place, so as to take timely measures. At the same time, the pressure sensor 488 controls the anti-slip motor 4102 at the corresponding end through an electrical signal, so that the movable hole 4103 and the rope groove 4105 are staggered, and the wire rope 49 is clamped inside the anti-slip frame 4101. At the same time, the locking tooth 4107 is squeezed on the surface of the wire rope 49, squeezing the wire rope 49 to prevent the wire rope 49 from falling off inside the anti-slip device 410, thereby preventing the wire rope 49 from falling off accidentally.

[0055] It should be noted that the present invention is an advertising device based on e-commerce. When in use, during the lifting process, the surrounding steel wire ropes 49 are unwound synchronously. As the lifting sling 3 descends, the telescopic inner frame 211 is affected by gravity. As the lifting sling 3 descends, it moves out and stretches inside the fixed sleeve 210, and finally, the embedded rod 34 is separated from the bottom of the telescopic inner frame 211 and descends. The lifting sling 3 descends to the top of the billboard, and the billboard hanger 35 is fixed to the top of the billboard by means of hooks or binding. When the lifting sling 3 descends, the embedded rod 34 is separated from the bottom of the movable inner rod 2112. At this time, the guide rope 2115 is affected by the descent of the embedded rod 34 and moves downward, and The sliding block 2114 is pulled to press the top of the return spring 2116. When the lifting sling 3 rises, the return spring 2116 will push the sliding block 2114 to rise inside the movable cavity 2113 through the reaction force, and guide the embedded rod 34 to facilitate the embedded rod 34 to be inserted into the bottom of the movable inner rod 2112, so as to avoid that after the lifting sling 3 is lowered, the embedded rod 34 is not convenient to be inserted into the bottom of the movable inner rod 2112 due to the shaking of the lifting sling 3. The steel wire rope 49 is limited to a certain extent by the fixed sleeve 210 and the telescopic inner frame 211 to prevent the steel wire rope 49 from being suspended in the air for too long during the lifting process, resulting in a large shaking of the steel wire rope 49 during the movement of the gantry 1 or the influence of wind.

[0056] During the hoisting process, the steel wire ropes 49 at both ends of the bottom of the fixed frame 45 pass through the bottom of the guide assembly 48, pass through the inside of the anti-falling device 410 and are movably connected to the top of the steering wheel 411. The steel wire ropes 49 are connected to the outer surface of the rotating wheel 32. At this time, while the limiting wheel 486 provides limiting support for the steel wire rope 49, the limiting wheel 486 is subjected to force and will generate upward pressure, so that the fixed shaft 484 moves up inside the movable groove 482, and the squeezing spring 489 is compressed. At the same time, the pressing block in the middle of the limiting frame 487 presses against the bottom of the pressure sensor 488, so that the pressure sensor 488 always feels the pressure. When the pressure sensor 488 is at a certain place, When the pressure sensed by the sensor 488 decreases, the hydraulic adjustment rod 44 at the corresponding position is controlled to contract through an electrical signal, so that the rotating rod 46 rotates on the side of the fixed frame 45, and the steering wheel 411 rises at one end of the wire rope 49 to adjust the position of the wire rope 49, and then the length of the wire rope 49, so that each wire rope 49 is kept in a taut and stretched state when the lifting sling 3 is hoisted, so that the load distribution of each wire rope 49 is even, so that the pressure values ​​of the four pressure sensors 488 at the bottom of the sliding seat 21 are at the same value, so that the four corners of the lifting sling 3 are stretched evenly, and the lifting sling 3 is kept level when stretched;

[0057] When the pressure sensor 488 at a certain place suddenly fails to sense the corresponding pressure after sensing the pressure, the indicator light 216 at that place is controlled to flash through an electrical signal, so that the operator can quickly understand the lifting situation and quickly determine whether the wire rope 49 at a specific place is broken or fallen off, so that timely measures can be taken. The pressure sensor 488 also controls the anti-falling motor 4102 at the corresponding end through an electrical signal. At this time, the rotating tube 4104 drives the wire rope 49 inside the rope groove 4105 to rotate, and the locking block 4106 rotates with the rotating tube 4104, so that the movable hole 4103 and the rope groove 4105 are staggered, and the wire rope 49 is clamped inside the anti-falling frame 4101. At the same time, the locking teeth 4107 on the side of the locking block 4106 are pressed on the surface of the wire rope 49, squeezing the wire rope 49 to prevent the wire rope 49 from falling off inside the anti-falling device 410, thereby preventing the wire rope 49 from accidentally falling off.
