A highway bridge subgrade pavement auxiliary construction device and a construction method thereof

Abstract

The application belongs to the field of highway bridge construction, and particularly relates to a highway bridge roadbed pavement auxiliary construction device and a construction method thereof. The existing warning board surface contains a large amount of dust, which leads to the fact that the warning board does not have a reflection effect and is more dangerous at night. If the warning board is not removed in time, vehicles will be misled, and the traditional warning board is light in weight and prone to collapse. The present application proposes the following scheme, which comprises a base, a water tank fixedly connected to the upper surface of the base, a support column fixedly connected to the upper surface of the water tank, and a first fixed plate fixedly connected to one side of the support column. In the application, the cleaning strip is used to clean the warning board, which is convenient for vehicles to check the warning board and has a good reflection effect at night. The second fixed plate drives the folding curtain to move upward, which is convenient for shielding the warning board. The spray head atomizes water, effectively reducing dust. The second rotating plate is fixed to the ground, which can effectively prevent the auxiliary construction device from collapsing.

Description

Technical Field

[0001] This invention relates to the field of highway bridge construction technology, and in particular to an auxiliary construction device for highway bridge subgrade and pavement and its construction method. Background Technology

[0002] With the booming development of my country's economic construction, highway bridge construction has also developed rapidly. In highway bridge construction, the roadbed and pavement are the most important components. The roadbed is the foundation of the pavement structure; a solid and stable roadbed provides crucial protection for the pavement structure to withstand vehicle loads over the long term. Meanwhile, the pavement structure layers protect the roadbed, preventing it from being directly damaged by vehicles and the atmosphere, thus maintaining its long-term stability. During highway roadbed construction, auxiliary devices are needed to protect and warn against unauthorized personnel from entering and disrupting the roadbed and pavement construction work.

[0003] A search revealed that utility model patent CN215562110U discloses an auxiliary device for highway subgrade construction, including a base. Two mounting slots are symmetrically formed on the top surface of the base, and a mounting plate is installed within each slot. The device, comprising a base, mounting slots, mounting plate, locking bolt, fixing plate, warning sign, enclosure, slot, and connecting mechanism, facilitates installation. However, the aforementioned patent has the following shortcomings:

[0004] 1. During the use of the above-mentioned auxiliary devices for highway subgrade construction, the surface of the warning signs will contain a lot of dust, which will cause them to lose their reflective properties, making them more dangerous at night and making it inconvenient for passing vehicles to see the warning signs;

[0005] 2. If warning signs are not removed in time when auxiliary devices for highway subgrade construction are not used, they will mislead vehicles. Leaving them outside will also cause dust to accumulate on their surface, making them difficult to cover. Traditional warning signs are relatively light, easy to collapse, and have poor fixing effect.

[0006] To address the aforementioned problems, this invention proposes an auxiliary construction device and construction method for highway bridge subgrade and pavement. Summary of the Invention

[0007] This invention provides an auxiliary construction device and method for roadbed and pavement of highway bridges, which solves the problems of existing warning signs, such as the presence of a large amount of dust on the surface of the warning signs, which makes them non-reflective and dangerous at night, the misleading effect of warning signs if they are not removed in time, the difficulty in covering them, and the easy collapse of traditional warning signs.

[0008] This invention provides the following technical solution:

[0009] A road bridge subgrade and pavement auxiliary construction device includes a base, a water tank is fixedly connected to the upper surface of the base, a support column is fixedly connected to the upper surface of the water tank, a first fixing plate is fixedly connected to one side of the support column, and a warning sign is fixedly connected to one side of the first fixing plate.

[0010] A first screw and a first sliding column are rotatably connected to one side of the first fixed plate. The first screw and the first sliding column are located on the same side of the first fixed plate. A motor is fixedly connected to the other side of the first fixed plate. A synchronous pulley is fixedly connected to one end of the first screw and one end of the motor output shaft. The two synchronous pulleys are connected by transmission. A threaded block is threaded to the circumference of the first screw. A connecting plate is fixedly connected to one side of the threaded block. The other end of the connecting plate is slidably connected to the first sliding column. A cleaning strip is provided on one side of the connecting plate. The cleaning strip contacts the warning sign.

[0011] In one possible design, a folding curtain is fixedly connected to the bottom of the first fixing plate, and a second fixing plate is fixedly connected to one end of the folding curtain. Both ends of the second fixing plate are provided with shielding components.

[0012] The shielding assembly includes a fixed post and a fixed cylinder. The fixed post is fixedly connected to the upper surface of the second fixed plate, and the fixed cylinder is fixedly connected to one side of the connecting plate. A "flying saucer"-shaped sliding block is slidably connected to the outer circumference of the fixed post. A hemispherical block is fixedly connected to the top of the fixed post. The diameter of the hemispherical block is the same as the widest diameter of the sliding block. An extension block is fixedly connected to one side of the fixed cylinder. A second sliding post is slidably connected inside the extension block. One end of the second sliding post is a slope. A spring is provided inside the extension block, and the second sliding post is located inside the circumference of the spring.

[0013] In one possible design, a water pump is fixedly connected to the upper surface of the water tank, an inlet pipe is fixedly connected to the inlet end of the water pump, the inlet pipe is fixedly connected to the water tank, a connecting pipe is fixedly connected to the outlet end of the water pump, and multiple nozzles are fixedly connected to the end of the connecting pipe.

[0014] In one possible design, a tilted solar panel is fixedly connected to one side of the support column, and a protective shell is fixedly connected between the two support columns. The protective shell contains a controller and a battery, respectively.

[0015] In one possible design, extension plates are fixedly connected to the four corners of the base, and rotating columns are threadedly connected to the upper surface of each extension plate. A tapered drill bit is fixedly connected to the bottom of each rotating column.

[0016] In one possible design, a first rotating plate is fixedly connected to one side of each extension plate, and a second screw is rotatably connected to the other side of each first rotating plate. A threaded sleeve is threadedly connected to the outer circumference of each second screw, and a second rotating plate is rotatably connected to the other end of each threaded sleeve. Two protrusions are fixedly connected to the circumference of each threaded sleeve.

[0017] In one possible design, the upper surface of the connecting plate is fixedly connected with a plurality of through screws, which pass through the cleaning strip and are threaded with nuts.

[0018] In one possible design, reflective strips are fixedly connected to all four sides of the water tank.

[0019] This invention also proposes a construction method for an auxiliary construction device for highway bridge subgrade and pavement, comprising the following steps:

[0020] S1: Push the auxiliary construction device to move it to a suitable position and fix it. Rotate multiple rotating columns to drive the drill bit downward and fix the drill bit in the soil. Then rotate the threaded sleeve to adjust the distance between the threaded sleeve and the second screw, and fix the second rotating plate on the ground. This can effectively prevent the auxiliary construction device from tipping over and has a good fixing effect.

[0021] S2: Fix the warning sign to the first fixing plate. When there is dust on the surface of the warning sign, the motor indirectly drives the first screw to rotate through the transmission of two synchronous pulleys. The first screw drives the threaded block to move, the threaded block drives the connecting plate to move, and the connecting plate drives the cleaning strip to move. The cleaning strip cleans the warning sign, making it easy for passing vehicles to see the warning sign and giving it a good reflective effect when used at night.

[0022] S3: The water pump draws water from the water tank through the inlet pipe, and sprays the water out through the connecting pipe and multiple nozzles. The nozzles facilitate the atomization of water, effectively reducing dust.

[0023] S4: When the warning sign needs to be covered, the first screw rotates, which drives the connecting plate to move downward through the threaded block. The connecting plate drives the fixed cylinder to move downward, allowing the hemispherical block to slide inside the fixed cylinder. When the second sliding column slides to the bottom of the hemispherical block, it gets stuck. At this time, the connecting plate moves upward, which in turn drives the second fixed plate to move upward. The second fixed plate drives the folding curtain to move upward, making it easier to cover the warning sign. When it is no longer necessary to cover the sign, the connecting plate moves downward to the bottom, so that the second sliding column is below the sliding block. Then, the fixed cylinder moves upward, so that the second sliding column is disengaged from the hemispherical block.

[0024] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0025] In this invention, the motor indirectly drives the first screw to rotate through the transmission of two synchronous pulleys. The first screw drives the threaded block to move, the threaded block drives the connecting plate to move, and the connecting plate drives the cleaning strip to move. The cleaning strip cleans the warning sign, making it easier for passing vehicles to see the warning sign and ensuring that it has a good reflective effect even when used at night.

[0026] In this invention, by setting up a folding curtain, when it is necessary to cover the warning sign, the first screw rotates, which drives the connecting plate to move downward through the threaded block. The connecting plate drives the fixing cylinder to move downward, allowing the hemispherical block to slide inside the fixing cylinder. When the second sliding column slides to the bottom of the hemispherical block, it gets stuck. At this time, it drives the connecting plate to move upward, which in turn drives the second fixing plate to move upward. The second fixing plate drives the folding curtain to move upward, making it easier to cover the warning sign. When it is not necessary to cover the sign, the connecting plate moves downward to the bottom, so that the second sliding column is located below the sliding block. Then, the fixing cylinder moves upward, so that the second sliding column is disengaged from the hemispherical block.

[0027] In this invention, by setting up a water tank, the water pump draws water from the water tank through the water inlet pipe, and sprays the water out through the connecting pipe and multiple nozzles. The nozzles facilitate the atomization of the water, effectively reducing dust.

[0028] In this invention, by setting the second rotating plate, rotating the threaded sleeve can adjust the distance between the threaded sleeve and the second screw, and fixing the second rotating plate on the ground can effectively prevent the auxiliary construction device from tipping over.

[0029] In this invention, the cleaning strip cleans the warning sign, making it easier for passing vehicles to see, and also providing good reflectivity at night. The second fixing plate moves the folding curtain upward to cover the warning sign, and the spray nozzle atomizes the water, effectively reducing dust. Fixing the second rotating plate to the ground effectively prevents the auxiliary construction device from tipping over. Attached Figure Description

Detailed Implementation

[0039] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0040] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the devices are connected to each other and their relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of the present invention, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0041] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0042] In this embodiment of the invention, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0043] References to "one embodiment" or "some embodiments" as used in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the invention. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically emphasized.

[0044] Example 1

[0045] Reference Figures 1-7 The auxiliary construction device includes: a base 1, a water tank 2 fixedly connected to the upper surface of the base 1, a support column 14 fixedly connected to the upper surface of the water tank 2, a first fixing plate 5 fixedly connected to one side of the support column 14, and a warning sign 6 fixedly connected to one side of the first fixing plate 5.

[0046] A first screw 9 and a first sliding column 26 are rotatably connected to one side of the first fixed plate 5. The first screw 9 and the first sliding column 26 are located on the same side of the first fixed plate 5. A motor 12 is fixedly connected to the other side of the first fixed plate 5. A synchronous wheel 13 is fixedly connected to one end of the first screw 9 and one end of the output shaft of the motor 12. The two synchronous wheels 13 are connected by transmission. A threaded block 27 is threadedly connected to the circumference of the first screw 9. A connecting plate 28 is fixedly connected to one side of the threaded block 27. The other end of the connecting plate 28 is slidably connected to the first sliding column 26. A cleaning strip 29 is provided on one side of the connecting plate 28. The cleaning strip 29 contacts the warning sign 6.

[0047] In the above technical solution, the warning sign 6 is fixed on the first fixing plate 5. When there is dust on the surface of the warning sign 6, the motor 12 indirectly drives the first screw 9 to rotate through the transmission of two synchronous pulleys 13. The first screw 9 drives the threaded block 27 to move, the threaded block 27 drives the connecting plate 28 to move, and the connecting plate 28 drives the cleaning strip 29 to move. The cleaning strip 29 cleans the warning sign 6, making it easy for oncoming vehicles to see the warning sign 6 and giving it a good reflective effect even at night. The main function of the warning sign 6 is to warn oncoming vehicles to slow down and pay attention to safety, but it is not limited to "construction ahead, slow down" in the attached drawings of this manual. It can also be other phrases, and different warning signs 6 can be replaced according to actual needs.

[0048] This application can be used for roadbed and pavement of highway bridges, as well as other fields applicable to this application.

[0049] Example 2

[0050] Based on Example 1, in Example 2:

[0051] Reference Figure 4 and Figure 5 The bottom of the first fixing plate 5 is fixedly connected to a folding curtain 30, and one end of the folding curtain 30 is fixedly connected to a second fixing plate 31. Both ends of the second fixing plate 31 are provided with shielding components.

[0052] The shielding assembly includes a fixed post 36 and a fixed cylinder 32. The fixed post 36 is fixedly connected to the upper surface of the second fixed plate 31, and the fixed cylinder 32 is fixedly connected to one side of the connecting plate 28. A "flying saucer" shaped sliding block 37 is slidably connected to the outer circumference of the fixed post 36. A hemispherical block 38 is fixedly connected to the top of the fixed post 36. The diameter of the hemispherical block 38 is the same as the diameter at the widest point of the sliding block 37. An extension block 33 is fixedly connected to one side of the fixed cylinder 32. A second sliding post 34 is slidably connected inside the extension block 33. One end of the second sliding post 34 is a slope. A spring 35 is provided inside the extension block 33. The second sliding post 34 is located inside the circumference of the spring 35.

[0053] In the above technical solution, when it is necessary to cover the warning sign 6, the first screw 9 rotates, which drives the connecting plate 28 to move downward through the threaded block 27. The connecting plate 28 drives the fixed cylinder 32 to move downward, so that the hemispherical block 38 slides inside the fixed cylinder 32. When the second sliding column 34 slides to the bottom of the hemispherical block 38, it gets stuck. At this time, it drives the connecting plate 28 to move upward, which drives the second fixed plate 31 to move upward. The second fixed plate 31 drives the folding curtain 30 to move upward, which facilitates the covering of the warning sign 6. When it is not necessary to cover it, the connecting plate 28 moves downward to the bottom, so that the second sliding column 34 is located below the sliding block 37. Then the fixed cylinder 32 is moved upward, so that the second sliding column 34 is disengaged from the hemispherical block 38.

[0054] Reference Figures 1-3 A water pump 11 is fixedly connected to the upper surface of the water tank 2. The water inlet end of the water pump 11 is fixedly connected to the water inlet pipe 25, which is fixedly connected to the water tank 2. The water outlet end of the water pump 11 is fixedly connected to the connecting pipe 7, and multiple nozzles 8 are fixedly connected to the end of the connecting pipe 7.

[0055] In the above technical solution, the water pump 11 draws water from the water tank 2 through the water inlet pipe 25, and sprays the water out through the connecting pipe 7 and multiple nozzles 8. The nozzles 8 facilitate the atomization of water, effectively reducing dust.

[0056] Reference Figure 3 A tilted solar panel 10 is fixedly connected to one side of the support column 14, and a protective shell 22 is fixedly connected between the two support columns 14. A controller 23 and a battery 24 are respectively installed inside the protective shell 22.

[0057] In the above technical solution, the solar panel 10 converts light energy into electrical energy, which is then stored in the battery 24 by the controller 23. No external power supply is required, making it convenient and a green energy source.

[0058] Reference Figure 7 An extension plate 3 is fixedly connected to each of the four corners of the base 1. A rotating column 15 is threadedly connected to the upper surface of the extension plate 3. A conical drill bit 16 is fixedly connected to the bottom of the rotating column 15.

[0059] One side of the extension plate 3 is fixedly connected to a first rotating plate 17, and the other side of the first rotating plate 17 is rotatably connected to a second screw 18. The outer circumference of the second screw 18 is threadedly connected to a threaded sleeve 19, and the other end of the threaded sleeve 19 is rotatably connected to a second rotating plate 20. The circumference of the threaded sleeve 19 is fixedly connected to two protrusions 21.

[0060] In the above technical solution, when fixing the auxiliary construction device, rotating multiple rotating columns 15 will drive the drill bit 16 to move downwards and fix the drill bit 16 in the soil. Then, rotating the threaded sleeve 19 can adjust the distance between the threaded sleeve 19 and the second screw 18, and fix the second rotating plate 20 on the ground. This can effectively prevent the auxiliary construction device from tipping over, and the fixing effect is good.

[0061] Reference Figure 6 The upper surface of the connecting plate 28 is fixedly connected with a plurality of through screws 39, the screws 39 passing through the cleaning strip 29 and being threadedly connected with nuts 40;

[0062] In the above technical solution, the cleaning strip 29 is located inside the connecting plate 28 and is fixed by multiple screws 39 and nuts 40. When it needs to be disassembled and replaced, the screws 39 and nuts 40 can be loosened, which is convenient and easy to replace.

[0063] Reference Figure 1 Reflective strips 4 are fixedly connected around the perimeter of water tank 2;

[0064] In the above technical solution, the reflective strip 4 makes it easy for oncoming vehicles to see the water tank 2 with their headlights, thus preventing them from colliding with this auxiliary construction device.

[0065] This invention also proposes a construction method for an auxiliary construction device for highway bridge subgrade and pavement, comprising the following steps:

[0066] S1: Push the auxiliary construction device to move it to a suitable position and fix it. Rotate multiple rotating columns 15 to drive the drill bit 16 to move downward and fix the drill bit 16 in the soil. Then rotate the threaded sleeve 19 to adjust the distance between the threaded sleeve 19 and the second screw 18 and fix the second rotating plate 20 on the ground. This can effectively prevent the auxiliary construction device from tipping over and has a good fixing effect.

[0067] S2: The warning sign 6 is fixed on the first fixing plate 5. When there is dust on the surface of the warning sign 6, the motor 12 indirectly drives the first screw 9 to rotate through the transmission of the two synchronous pulleys 13. The first screw 9 drives the threaded block 27 to move, the threaded block 27 drives the connecting plate 28 to move, and the connecting plate 28 drives the cleaning strip 29 to move. The cleaning strip 29 cleans the warning sign 6, making it easy for passing vehicles to see the warning sign 6 and giving it a good reflective effect when used at night.

[0068] S3: Water pump 11 draws water from water tank 2 through water inlet pipe 25, and sprays the water out through connecting pipe 7 and multiple nozzles 8. The nozzles 8 facilitate water atomization, effectively reducing dust.

[0069] S4: When it is necessary to cover the warning sign 6, the first screw 9 rotates, which drives the connecting plate 28 to move downward through the threaded block 27. The connecting plate 28 drives the fixed cylinder 32 to move downward, so that the hemispherical block 38 slides inside the fixed cylinder 32. When the second sliding column 34 slides to the bottom of the hemispherical block 38, it gets stuck. At this time, it drives the connecting plate 28 to move upward, which drives the second fixed plate 31 to move upward. The second fixed plate 31 drives the folding curtain 30 to move upward, which facilitates the covering of the warning sign 6. When it is not necessary to cover it, the connecting plate 28 moves downward to the bottom, so that the second sliding column 34 is located below the sliding block 37. Then the fixed cylinder 32 is moved upward, so that the second sliding column 34 is disengaged from the hemispherical block 38.

[0070] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 12, water pump 11, battery 24 and controller 23 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0071] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
