Description

Technical Field

[0001] This invention relates to the technical field of highway construction, specifically to a rural highway construction fence. Background Technology

[0002] In the process of rural road construction, in order to improve the safety of the construction environment and prevent non-construction personnel from approaching the construction site, it is necessary to use construction fences to block off the area, thereby ensuring the smooth progress of construction and also serving as a warning to pedestrians and vehicles. For example, a road construction fence with announcement number CN222686337U includes a box body with a mesh frame on the top and an inner cavity inside. A swing plate is hinged to the front and rear sides of the bottom of the inner cavity. A rotating threaded shaft and a sliding rod are installed inside the inner cavity. A lifting plate is slidably installed on the outside of the sliding rod. The lifting plate is threadedly connected to the rotating threaded shaft. Multiple rotating seats are installed at the bottom of the lifting plate. A swing rod is hinged to the rotating seat and is hinged to one side of the swing plate. When unfolded, this road construction fence forms a strong base structure with the swing plate and the counterweight plate, allowing the road construction fence to be placed independently.

[0003] For example, a construction fence for highway safety construction, with announcement number CN210422127U, includes supporting side posts, a central post, and fence units. Each fence unit consists of a first fence body, a second fence body, and a third fence body. Sliding grooves are provided inside one side of the supporting side posts and both sides of the central post. The first, second, and third fence bodies are slidably installed within these grooves of the supporting side posts and the central post via connecting seats. The central post is composed of a first post and a second post, which are hinged together using hinges and screws. This construction fence for highway safety construction is used for protection during highway safety construction. The first, second, and third fence bodies are slidably installed within the grooves of the supporting side posts and the central post via connecting seats, allowing the fence to be adjusted in width as needed and retracted for easy carrying and use. However, the above-mentioned construction fence still has the following drawbacks in actual use:

[0004] 1. Traditional construction fences have a limited enclosure area. When a larger area needs to be maintained, multiple fences need to be spliced ​​together, which is inconvenient to operate and not convenient to store.

[0005] 2. Since construction sites are not fenced off on one side, and traditional construction fences are not convenient for fencing off multiple sides at the same time, multiple fences still need to be spliced ​​together.

[0006] 3. At the same time, the construction site will generate a lot of dust during construction operations. Traditional construction fences lack the structure to suppress dust, which has a significant impact on the construction environment.

[0007] To address the aforementioned issues, there is an urgent need for innovative designs based on existing highway construction fencing. Summary of the Invention

[0008] The purpose of this invention is to provide a rural road construction fence to solve the problems mentioned in the background art, which are that traditional construction fences require splicing to achieve a larger area of ​​enclosure and multi-faceted enclosure, and also lack a structure to suppress dust.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a rural road construction fence, comprising a support box, wherein the bottom of the support box is bolted with movable wheels, and a first fence and a second fence are respectively installed on the top of the support box. The first fence and the second fence form a rectangular frame structure, and both the first fence and the second fence are composed of uprights and horizontal posts, and the uprights and horizontal posts are perpendicular to each other.

[0010] It also includes: a booster mechanism, disposed between the first fence and the second fence, wherein the booster mechanism enables the first fence and the second fence to move in opposite directions;

[0011] The dust suppression mechanism is located on one side opposite to the two horizontal columns. The dust suppression mechanism is in communication with the liquid inside the support box and suppresses dust by spraying.

[0012] A protective mechanism is installed inside the post, which is used to expand the protective area of ​​the fence.

[0013] Preferably, the bottom of the left-side column and the bottom of the lower horizontal column are both fixed with support rods, and the bottom of the support rods are equipped with movable wheels. The sides of the support rods are fixed with fixed rods, and the fixed rods slide through the support box. When the two sets of fences move away from each other, they can slide through the movable wheels and drive the fixed rods to slide within the support box to maintain stability.

[0014] Preferably, the booster mechanism includes a connecting rod fixed to the column, and the connecting rod and the column are perpendicular to each other. The connecting rod slides through the horizontal column, and a piston block is fixed at the end of the connecting rod away from the column. When the two columns move away from each other, the connecting rod slides inside the horizontal column.

[0015] Preferably, the crossbar has a fixed cavity, and the edge of the piston block slides against the inner wall of the fixed cavity. The connecting rod below is hollow, and an air inlet is reserved at the end of the connecting rod near the piston block. When the connecting rod moves, it drives the piston block to move synchronously, thereby squeezing the gas in the fixed cavity below into the hollow cavity inside the connecting rod through the air inlet.

[0016] Preferably, the end of the connecting rod away from the air inlet is fixedly connected to one end of the air supply pipe, and the other end of the air supply pipe is fixed on the upper horizontal column. The lower connecting rod is connected to the interior of the upper fixed cavity through the air supply pipe. The gas in the lower connecting rod can be transmitted to the upper fixed cavity through the air supply pipe and pushed by the upper piston block to move the upper connecting rod.

[0017] Preferably, the dust suppression mechanism includes a fixed pipe fixed to a horizontal column, and connecting pipes are provided at equal intervals on the side of the fixed pipe. A spray nozzle is provided in the middle of the connecting pipe. At the same time, the two sets of fixed pipes on the two horizontal columns are staggered. Liquid can enter the connecting pipe through the fixed pipe and finally be discharged from the spray nozzle to achieve the dust suppression effect.

[0018] Preferably, a motor is installed on the side of the support box, and the output shaft of the motor is connected to a lead screw. The lead screw has two symmetrically arranged threaded grooves in opposite directions. The lead screw and the piston plate are threadedly connected, and the piston plate and the fixed rod are slidably connected. When the lead screw rotates, it can drive the two piston plates away from or towards each other through the threaded transmission with the piston plate.

[0019] Preferably, the edge of the piston plate slides against the inner wall of the support box, and the inner top surface of the support box is provided with an infusion channel. The support box is connected to the inside of the fixed pipe through the infusion channel and the hose. The hose is fixed between the support box and the lower fixed pipe. At the same time, the hose is connected to the upper fixed pipe through the infusion pipe. When the two piston plates approach each other, they can squeeze the liquid in the support box and transfer it to the hose and the infusion pipe through the infusion channel.

[0020] Preferably, the protective mechanism includes a movable shaft rotatably disposed inside a column, and the column is hollow. The movable shaft is installed inside the column by a spiral spring. Meanwhile, a protective net is wrapped around the outside of the movable shaft, and the edge of the protective net is fixed to a mounting plate. When the mounting plate is pulled, the protective net can be extended to provide multi-faceted protection.

[0021] Preferably, the mounting plate is snapped into the opening of the column, and a connecting plate is fixed to the bottom of the mounting plate. The connecting plate has an "L" shaped structure, and a ground-inserting rod slides through the horizontal section of the connecting plate. After the mounting plate moves, it can push the ground-inserting rod downward to insert it into the ground, thereby ensuring the stability of the protective net after stretching.

[0022] Compared with the prior art, the beneficial effects of this invention are: the length of the rural road construction fence can be adjusted according to construction needs to achieve a larger area of ​​enclosure, and it can also provide multi-faceted enclosure of the construction site, making the fence applicable to a wider range. Furthermore, during maintenance, dust can be suppressed through spraying, improving the construction environment. Specific details are as follows:

[0023] 1. Pulling one of the columns causes the connecting rod to slide inside the horizontal column. The movement of the piston block compresses the gas inside the fixed cavity, causing the gas to enter the connecting rod below through the air inlet. Then, the gas is transmitted to the fixed cavity above through the gas pipe, pushing the piston block above to move. In this way, pulling one column can drive the other column to move in the opposite direction. The first fence and the second fence increase the protection range by moving away from each other.

[0024] 2. Through the threaded transmission between the lead screw and the piston plate, the two piston plates are driven to move closer to each other, squeezing the liquid in the support box and transmitting it through the infusion channel to the hose. Then the liquid enters the fixed pipe below and can also be transmitted through the infusion tube to the fixed pipe above, and finally enters the connecting pipe and is discharged from the spray nozzle to play a role in dust suppression.

[0025] 3. Pull the mounting plate to separate it from the post. This will extend the protective netting that is rolled up on the movable shaft. After extension, it will be perpendicular to the fence, providing three-sided protection for the construction site. This eliminates the need to splice multiple fences to achieve multi-sided maintenance. Attached Figure Description

[0035] 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.

[0036] Please see Figures 1-8 The present invention provides the following technical solution:

[0037] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a rural road construction fence, comprising a support box 1, with movable wheels 2 bolted to the bottom of the support box 1, and a first fence 3 and a second fence 4 respectively installed above the support box 1. The first fence 3 and the second fence 4 form a rectangular frame structure, and both the first fence 3 and the second fence 4 are composed of uprights 5 and horizontal posts 8, with the uprights 5 and horizontal posts 8 perpendicular to each other; further comprising: a booster mechanism, disposed between the first fence 3 and the second fence 4, which enables the first fence 3 and the second fence 4 to move in opposite directions; a dust suppression mechanism, disposed on one side opposite to the two horizontal posts 8, which communicates with the liquid inside the support box 1 to suppress dust by spraying; and a protective mechanism, disposed inside the uprights 5, which expands the protective area of ​​the fence.

[0038] Existing construction fences have limited enclosure area. When larger-area maintenance is required, multiple fences need to be spliced ​​together, which is inconvenient to operate and store. Figures 1-3As shown, support rods 15 are fixed to the bottom of the left column 5 and the bottom of the lower horizontal column 8. The bottom of the support rods 15 is equipped with casters 2, and a fixing rod 16 is fixed to the side of the support rods 15, which slides through the support box 1. The pushing mechanism includes a connecting rod 6 fixed to the column 5, perpendicular to the column 5, and sliding through the horizontal column 8. A piston block 7 is fixed to the end of the connecting rod 6 away from the column 5. A fixing cavity 9 is provided inside the horizontal column 8, and the edge of the piston block 7 slides against the inner wall of the fixing cavity 9. The lower connecting rod 6 is hollow, and an air inlet 10 is provided at the end of the connecting rod 6 near the piston block 7. The end of the connecting rod 6 away from the air inlet 10 is fixedly connected to one end of the air supply pipe 11, and the other end of the air supply pipe 11 is fixed to the upper horizontal column 8. The lower connecting rod 6 communicates with the interior of the upper fixing cavity 9 through the air supply pipe 11. First, the construction fence is pushed to the designated position using the casters 2. The construction site can be directly protected by the first fence 3 and the second fence 4. When the area to be protected is large, one of the columns 5 can be pulled to drive the connecting rod 6 to slide inside the horizontal column 8. When the lower connecting rod 6 moves, it drives the piston block 7 to slide inside the fixed cavity 9. The piston block 7 compresses the gas inside the fixed cavity 9, causing the gas to enter the lower connecting rod 6 through the air inlet 10. Then the gas can be transmitted to the upper fixed cavity 9 through the air supply pipe 11 and push the upper piston block 7 to move. In this way, pulling one column 5 can drive the other column 5 to move in the opposite direction. The first fence 3 and the second fence 4 increase the protection range by moving away from each other. The fixed pipe 12 and the connecting pipe 13 on the two columns 5 are staggered and separated, so the column 5 will not be affected when moving. The fixed pipe 12 and the connecting pipe 13 can achieve the protection effect. When storing, only one column 5 needs to be pushed to realize the automatic storage of the other column 5, which improves the convenience of operation.

[0039] Example 2: Since construction sites generate a large amount of dust during operations, traditional construction fences lack structures to suppress this dust, significantly impacting the construction environment. Therefore, this example addresses this issue through the following technical solution: Figures 6-8As shown, the dust suppression mechanism includes a fixed pipe 12 fixed to a horizontal column 8, and connecting pipes 13 are evenly spaced on the side of the fixed pipe 12. A spray nozzle 14 is located in the middle of the connecting pipe 13. The two sets of fixed pipes 12 on the two horizontal columns 8 are staggered. A motor 17 is installed on the side of the support box 1, and the output shaft of the motor 17 is connected to a lead screw 18. The lead screw 18 has two symmetrically arranged threaded grooves in opposite directions. The lead screw 18 and the piston plate 19 are threadedly connected, and the piston plate 19 and the fixed rod 16 are slidably connected. The edge of the piston plate 19 slides against the inner wall of the support box 1. An infusion channel 20 is opened on the inner top surface of the support box 1. The support box 1 is connected to the inside of the fixed pipe 12 through the infusion channel 20 and the hose 21. The hose 21 is fixed to the support box 1 and the fixed rod 16 below. Between the fixed pipes 12, the hose 21 is connected to the upper fixed pipe 12 through the infusion pipe 22; when the first fence 3 and the second fence 4 are deployed, the protection range is larger, and the construction site is also larger. More dust will be generated during construction. At this time, the motor 17 drives the lead screw 18 to rotate. Through the thread transmission between the lead screw 18 and the piston plate 19, the two piston plates 19 are driven to move closer to each other. By squeezing the liquid in the support box 1, the liquid is transferred through the infusion channel 20 to the hose 21. Then the liquid enters the lower fixed pipe 12 and can also be transferred through the infusion pipe 22 to the upper fixed pipe 12. Finally, it enters the connecting pipe 13 and is discharged from the spray nozzle 14 to play a role in dust suppression. Since the first fence 3 and the second fence 4 are in the deployed state, the distribution range of the spray nozzle 14 is also increased, which improves the dust suppression effect.

[0040] Example 3: Since construction sites are not fenced off on one side, and traditional construction fences are inconvenient for simultaneously fencing multiple sides, requiring multiple fences to be pieced together, this example uses the following technical solution: Figures 4-5 As shown, the protective mechanism includes a movable shaft 23 rotatably mounted inside a column 5, which is hollow. The movable shaft 23 is installed inside the column 5 via a spiral spring. A protective net 24 is wound around the outside of the movable shaft 23, and the edge of the protective net 24 is fixed to a mounting plate 25. The mounting plate 25 is engaged at the opening of the column 5, and a connecting plate 26 is fixed to the bottom of the mounting plate 25. The connecting plate 26 has an "L" shape, and a ground-inserting rod 27 slides through the horizontal section of the connecting plate 26. When the construction site requires multi-sided protection, the mounting plate 25 can be pulled to separate it from the column 5, thus extending the protective net 24 wound on the movable shaft 23. After extension, it becomes perpendicular to the fence, providing three-sided protection for the construction site. After movement, the ground-inserting rod 27 is pushed to insert it into the ground, ensuring the stability of the mounting plate 25. When the protective net 24 is not in use, the mounting plate 25 is brought close to the column 5, and the protective net 24 is automatically wound up by the elasticity of the spiral spring.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
