Description

Technical Field

[0001] This invention relates to the field of pedestrian bridge ground cover technology, specifically to a pollution prevention device for painted railings on pedestrian bridge ground covers. Background Technology

[0002] As urban landscape elements, municipal bridges are scenic features that demand high aesthetic standards. Bridge railings are one of the core components of landscape bridges. Railings are often designed with irregular shapes, and their colors and connections to the ground vary accordingly. Painting must be done after the railings are connected to the ground. During the painting process at the ground and connection points, it is inevitable that the bridge railings will be contaminated. Furthermore, using a single barrier cannot completely protect the railings. Summary of the Invention

[0003] The purpose of this invention is to provide a pollution prevention device for painted railings on pedestrian bridges, so as to solve the problem of pollution to bridge railings.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

A pull handle is provided on one side of the limiting plate. An anti-detachment rope is provided on the side of the pull handle away from the limiting plate, and the other end of the anti-detachment rope is connected to the connecting bottom block.

[0015] Preferably, the range extender includes a fixed block, an active movable block, and a driven movable block. The fixed block is fixed inside the protective baffle. Both the active and driven movable blocks are located inside the protective baffle. There are at least two driven movable blocks arranged in a straight line. Both the active and driven movable blocks are connected to the end of the corresponding second guide rod away from the connecting bottom block. A movable connecting plate is provided on the side of the driven movable block away from the second guide rod. The active movable block has the same number of fixed columns as the driven movable blocks from top to bottom, and pulleys are sleeved on the fixed columns.

[0016] Preferably, at least two pulleys are provided. The number of pulleys fitted on the fixed column at the upper end of the active movable block is the same as the number of driven movable blocks, and the number of pulleys on the fixed column decreases from top to bottom. The fixed block is provided with one less fixed column than the number of driven movable blocks from top to bottom, and the fixed column on the fixed block is fitted with pulleys. The number of pulleys fitted on the fixed column at the upper end of the fixed block is one less than the number of driven movable blocks, and the number of pulleys decreases from top to bottom.

[0017] Preferably, a fixing plate is provided on one side of the fixing block, and a sliding rope is provided on the side of the fixing plate near the active moving block. The number of sliding ropes is the same as that of the driven moving block, and the other end of each sliding rope passes around the pulley and is connected to the corresponding movable connecting plate.

[0018] Preferably, the driven movable block includes a first movable block, a second movable block, and a third movable block; the movable connecting plate includes a first connecting plate, a second connecting plate, and a third connecting plate; the first connecting plate is located on the first movable block; the second connecting plate is located on the second movable block; and the third connecting plate is located on the third movable block. The sliding rope includes a first sliding rope, a second sliding rope, and a third sliding rope; the first sliding rope passes over one pulley and is connected to the first connecting plate; the second sliding rope passes over three pulleys and is connected to the second connecting plate; and the third sliding rope passes over five pulleys and is connected to the third connecting plate.

[0019] Preferably, a traction block is provided at the bottom of one side of the fixed block and the active movable block. A traction groove is provided in the traction block, and a traction shaft is provided in the traction groove. The traction shaft is hinged to the traction block, and a coil spring is sleeved on the outside of the traction shaft. The coil spring is a coiled spring sheet, and one end is connected to the traction shaft. The other end is provided with a traction rope, and the end of the traction rope away from the coil spring passes through the traction block and is connected to the side of the movable connecting plate away from the sliding rope.

[0020] Preferably, the top of the protective baffle is provided with a first guide groove, and a first guide rod is provided at the position of the active movable block corresponding to the first guide groove. The first guide rod is slidably disposed in the first guide groove, and a slider is provided on the outside of the protective baffle at the position of the first guide rod. One end of the first guide rod is connected to the active movable block, and the other end is connected to the slider.

[0021] Preferably, the slider has pressing grooves on both sides, pressing blocks are slidably disposed in the pressing grooves, and elastic elements are disposed between the pressing blocks and the pressing grooves. The elastic elements include pressing springs, one end of which is connected to the pressing blocks and the other end of which is connected to the pressing grooves. The top of the protective baffle has a guide limiting groove, which is located on both sides of the first guide groove. The bottom of the pressing groove has a limiting slide groove, and a limiting block is disposed in the limiting slide groove. One end of the limiting block is connected to the pressing blocks, and the other end is inserted into the guide limiting groove.

[0022] Preferably, the protective clips include, but are not limited to, a first clip, a second clip, a third clip, a fourth clip, a fifth clip, and a sixth clip.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] This invention places a protective baffle on the outer side above the connection between the bridge railing and the ground cover, and then clamps the railing with a protective clip to protect it, thereby preventing pollution of the bridge railing during the spraying process on the ground cover and the connection between the railing and the ground cover of the municipal landscape bridge.

[0025] By pressing the pressing block, the pressing block drives the limiting block from the guide slide into the limiting groove. Then, the slider moves, thereby driving the active moving block to move through the first guide rod. The active moving block drives the fixed column and pulley to move. The coil spring holds the traction rope, so that the traction rope always pulls the movable connecting plate, ensuring that the sliding rope is taut. Thus, the first connecting plate drives the driven moving block to move through the cooperation of the first sliding rope and the pulley, and the moving distance is twice the moving distance of the active moving block. The second connecting plate drives the driven moving block to move through the cooperation of the second sliding rope and the pulley, and the moving distance is four times the moving distance of the active moving block. The third connecting plate drives the driven moving block to move through the cooperation of the third sliding rope and the pulley, and the moving distance is six times the moving distance of the active moving block. This allows the spacing between adjacent sets of driven moving blocks and between driven and active moving blocks to increase or decrease simultaneously, making it easy to adapt to railings with different gaps.

[0026] Pull the limit plate out of the connecting base block by pulling the handle, and detach the limit plate from the connecting base block by detaching it from the connecting base block. Disassemble the protective clip by detaching the connecting clip from the connecting slot, making it easy to replace different protective clips to fit different sizes of railings.

[0039] Example 2:

[0040] like Figure 2 , Figure 5-6 As shown, the anti-pollution device for painted railings on pedestrian bridges disclosed in Embodiment 2 of the present invention has a structure that is basically the same as that in Embodiment 1. The difference is that the connecting block 9 is limited, and a limiting plate 12 is provided at the top of the connecting block 9 in the connecting slot 11. The limiting plate 12 passes through the connecting bottom block 7. A pull handle 28 is provided on one side of the limiting plate 12, and an anti-detachment rope 22 is provided on the side of the pull handle 28 away from the limiting plate 12. The other end of the anti-detachment rope 22 is connected to the connecting bottom block 7.

[0041] The limiting insert 12 passes through the connecting base block 7 and is located above the connecting clip block 9, thereby limiting the connecting clip block 9 and connecting the connecting base block 7 with the protective clip 8.

[0042] Example 3:

[0043] like Figure 2 As shown, the anti-pollution device for painted railings on pedestrian bridges disclosed in Embodiment 3 of the present invention has a structure that is basically the same as that in Embodiment 2. The difference is that the active movable block 13 drives the driven movable block 27 to move. The range extender includes a fixed block 23, an active movable block 13, and a driven movable block 27. The fixed block 23 is fixed inside the protective baffle 1. Both the active movable block 13 and the driven movable block 27 are set inside the protective baffle 1. There are at least two driven movable blocks 27, which are arranged in a straight line. Both the active movable block 13 and the driven movable block 27 are connected to the end of the corresponding second guide rod 10 away from the connecting bottom block 7. A movable connecting plate 25 is provided on the side of the driven movable block 27 away from the second guide rod 10. The active movable block 13 has the same number of fixed columns 15 as the driven movable blocks 27 from top to bottom. A pulley 16 is sleeved on the fixed column 15.

[0044] At least two pulleys 16 are provided. The number of pulleys 16 fitted on the fixed column 15 at the upper end of the active movable block 13 is the same as the number of driven movable blocks 27, and the number of pulleys 16 on the fixed column 15 decreases from top to bottom. The fixed block 23 is provided with one less fixed column 15 than the number of driven movable blocks 27 from top to bottom, and the fixed column 15 on the fixed block 23 is fitted with pulleys 16. The number of pulleys 16 fitted on the fixed column 15 at the upper end of the fixed block 23 is one less than the number of driven movable blocks 27, and the number of pulleys 16 decreases from top to bottom.

[0045] A fixing plate 24 is provided on one side of the fixing block 23. A sliding rope 17 is provided on the side of the fixing plate 24 near the active moving block 13. The number of sliding ropes 17 is the same as that of the driven moving block 27. The other end of each sliding rope 17 passes around the pulley 16 and is connected to the corresponding movable connecting plate 25.

[0046] Driven movable block 27 includes a first movable block 2701, a second movable block 2702, and a third movable block 2703. Movable connecting plate 25 includes a first connecting plate 2501, a second connecting plate 2502, and a third connecting plate 2503. The first connecting plate 2501 is located on the first movable block 2701, the second connecting plate 2502 is located on the second movable block 2702, and the third connecting plate 2503 is located on the third movable block 2703. Sliding rope 17 includes a first sliding rope 1701, a second sliding rope 1702, and a third sliding rope 1703. The first sliding rope 1701 passes over one pulley 16 and is connected to the first connecting plate 2501. The second sliding rope 1702 passes over three pulleys 16 and is connected to the second connecting plate 2502. The third sliding rope 1703 passes over five pulleys 16 and is connected to the third connecting plate 2503.

[0047] By moving the active movable block 13, the active movable block 13 drives the fixed column 15 and pulley 16 to move. The coil spring 31 pulls the traction rope 26, so that the traction rope 26 always pulls the movable connecting plate 25, ensuring that the sliding rope 17 is taut. Thus, the first connecting plate 2501 drives the driven movable block 27 to move through the cooperation of the first sliding rope 1701 and the pulley 16, and the moving distance is twice the moving distance of the active movable block 13. The second connecting plate 2502 drives the driven movable block 27 to move through the cooperation of the second sliding rope 1702 and the pulley 16, and the moving distance is four times the moving distance of the active movable block 13. The third connecting plate 2503 drives the driven movable block 27 to move through the cooperation of the third sliding rope 1703 and the pulley 16, and the moving distance is six times the moving distance of the active movable block 13.

[0048] Example 4:

[0049] like Figure 1-4As shown, the anti-pollution device for painted railings on pedestrian bridges disclosed in Embodiment 4 of the present invention has a structure that is basically the same as that in Embodiment 2. The difference is that the active movable block 13 is limited, a first guide groove 2 is provided at the top of the protective baffle 1, and a first guide rod 18 is provided at the position of the active movable block 13 corresponding to the first guide groove 2. The first guide rod 18 is slidably disposed in the first guide groove 2, and a slider 4 is provided at the position of the first guide rod 18 corresponding to the outside of the protective baffle 1. One end of the first guide rod 18 is connected to the active movable block 13, and the other end is connected to the slider 4.

[0050] The slider 4 has pressing grooves 20 on both sides. A pressing block 5 is slidably arranged in the pressing groove 20. An elastic element is provided between the pressing block 5 and the pressing groove 20. The elastic element includes a pressing spring 21. One end of the pressing spring 21 is connected to the pressing block 5, and the other end is connected to the pressing groove 20.

[0051] The top of the protective baffle 1 is provided with a guide limiting groove 3, which is located on both sides of the first guide groove 2. The bottom of the pressing groove 20 is provided with a limiting slide groove 32, and a limiting block 19 is provided in the limiting slide groove 32. One end of the limiting block 19 is connected to the pressing block 5, and the other end is inserted into the guide limiting groove 3. The guide limiting groove 3 includes a guide slide groove 301 and a limiting groove 302. The limiting groove 302 is set parallel to the first guide groove 2. There are at least two guide slide grooves 301, which are perpendicularly connected to the side of the guide slide groove 301 away from the first guide groove 2. The limiting grooves 302 are linearly distributed.

[0052] The pressing spring 21 presses the pressing block 5, which drives the limiting block 19 into the guide groove 301, thereby limiting the first guide rod 18 and the active moving block 13 and preventing the active moving block 13 from moving.

[0053] The specific solution is as follows: by placing the protective baffle 1 on the outer side above the connection between the bridge railing and the ground cover, and then clamping and protecting the railing with the protective clip 8, the solution prevents pollution of the bridge railing during the spraying process of the ground cover and the connection between the railing and the ground cover of the municipal landscape bridge.

[0054] By pressing the pressing block 5, the pressing block 5 drives the limiting block 19 from the guide groove 301 into the limiting groove 302. Then, the slider 4 is moved, thereby driving the active movable block 13 to move through the first guide rod 18. The active movable block 13 drives the fixed column 15 and pulley 16 to move. The coil spring 31 holds the traction rope 26, so that the traction rope 26 always pulls the movable connecting plate 25, ensuring that the sliding rope 17 is taut. Thus, the first connecting plate 2501 drives the driven movable block 27 to move through the cooperation of the first sliding rope 1701 and the pulley 16, and the moving distance is the same as the main moving block 27. The moving distance of the active moving block 13 is twice that of the moving block 13. The second connecting plate 2502 drives the driven moving block 27 to move through the cooperation of the second sliding rope 1702 and the pulley 16, and the moving distance is four times that of the active moving block 13. The third connecting plate 2503 drives the driven moving block 27 to move through the cooperation of the third sliding rope 1703 and the pulley 16, and the moving distance is six times that of the active moving block 13. This allows the spacing between two adjacent sets of driven moving blocks 27 and between driven moving blocks 27 and active moving blocks 13 to increase or decrease simultaneously, making it easy to adapt to railings with different gaps.

[0055] Pull the limiting insert 12 out of the connecting base block 7 by pulling the handle 28, and release the limiting insert 12 from the connecting base block 7 by the anti-detachment rope 22. Remove the protective clip 8 by releasing the connecting clip 9 from the connecting clip slot 11, so as to facilitate the replacement of different protective clips 8 and thus adapt to railings of different sizes.

[0056] 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.
