Description

Technical Field

[0001] The present invention relates to the technical field related to highway construction, in particular to a rural highway construction fence. Background Art

[0002] During the construction of rural roads, 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 for enclosure, thereby ensuring smooth construction and serving as a warning to pedestrians and vehicles. For example, a highway construction fence with announcement number CN222686337U comprises a box body, a grid is provided on the top of the box body, an inner cavity is provided in the box body, a swing plate is hingedly provided on the front and rear sides of the bottom of the inner cavity, a rotating threaded shaft and a sliding rod are provided in the inner cavity, a lifting plate is provided for sliding on the outer side of the sliding rod, the lifting plate is threadedly connected to the rotating threaded shaft, a plurality of rotating seats are provided at the bottom of the lifting plate, a swing rod is hingedly provided in the rotating seat, and the swing rod is hinged to one side of the swing plate. After the highway construction fence is unfolded, the swing plate and the counterweight plate form a strong base structure so that the highway construction fence can be placed separately; For example, a construction fence for highway safety construction with announcement number CN210422127U includes supporting side posts, a middle post and a fence unit, wherein the fence unit is composed of a first fence body, a second fence body and a third fence body, and a slide groove is provided inside one side of the supporting side posts and both sides of the middle post. The first fence body, the second fence body and the third fence body are slidably installed in the slide grooves of the supporting side posts and the middle post via a connecting seat, and the middle post is composed of a first post and a second post, and the first post and the second post are hingedly connected by hinges and screws. The construction fence for highway safety construction is used for highway safety construction protection. The first fence body, the second fence body and the third fence body are slidably installed in the slide grooves of the supporting side posts and the middle post via a connecting seat, so that the fence can adjust its use width as needed and can be retracted for easy carrying and use. However, the above-mentioned construction fence still has the following disadvantages during actual use: 1. Traditional construction fences have limited enclosure area. When a larger area of maintenance is required, multiple fences need to be spliced together, which is inconvenient to operate and not convenient for storage. 2. Since the construction site is 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; 3. At the same time, a large amount of dust will be generated during construction work at the construction site. Traditional construction fences lack structures to suppress dust, which has a great impact on the construction environment.

[0003] In response to the above problems, it is urgent to carry out innovative design based on the original highway construction fence. Summary of the Invention

[0004] The purpose of the present invention is to provide a rural road construction fence to solve the problem proposed in the above background technology that traditional construction fences need to be spliced to achieve a larger area of enclosure and multi-sided enclosure, and also lack a structure to suppress dust.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a rural road construction fence, comprising a support box, wherein movable wheels are mounted on the bottom of the support box via bolts, and a first fence and a second fence are mounted above the support box, respectively, wherein the first fence and the second fence form a rectangular frame structure, and each of the first fence and the second fence is composed of vertical posts and horizontal posts, and the vertical posts and the horizontal posts are perpendicular to each other; The invention also includes: a boosting mechanism, which is arranged between the first fence and the second fence, and the boosting mechanism enables the first fence and the second fence to move in opposite directions; A dust reduction mechanism is provided on one side opposite to the two horizontal columns, and the dust reduction mechanism is in communication with the liquid inside the support box to reduce dust by spraying; The protection mechanism is arranged inside the upright post and is used to expand the protection area of the fence.

[0006] Preferably, support rods are fixed to the bottom of the upright column on the left and the bottom of the horizontal column below, and movable wheels are installed at the bottom of the support rods, and fixed rods are fixed to the sides of the support rods. At the same time, 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 in the support box to maintain stability.

[0007] Preferably, the boosting mechanism includes a connecting rod fixed on the column, and the connecting rod and the column are perpendicular to each other, and the connecting rod slides through the horizontal column. At the same time, a piston block is fixed on the end of the connecting rod away from the column, and when the two columns move away from each other, the connecting rod is driven to slide inside the horizontal column.

[0008] Preferably, a fixed cavity is opened in the horizontal column, and the edge of the piston block slides in contact with the inner wall of the fixed cavity. The connecting rod below is hollow inside, and an air inlet is reserved at one end of the connecting rod close to 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 cavity inside the connecting rod through the air inlet.

[0009] Preferably, the end of the connecting rod away from the air inlet is fixedly connected to one end of the gas pipe, and the other end of the gas pipe is fixed on the upper horizontal column, and the lower connecting rod is connected to the interior of the upper fixed cavity through the gas pipe. The gas in the lower connecting rod can be transmitted to the upper fixed cavity through the gas pipe, and the upper connecting rod is pushed to move by the upper piston block.

[0010] Preferably, the dust reduction mechanism includes a fixed pipe fixed on a horizontal column, and connecting pipes are arranged at equal intervals on the side of the fixed pipe, and a spray nozzle is arranged in the middle of the connecting pipe. At the same time, the two groups of fixed pipes on the two horizontal columns are staggered, and the liquid can enter the connecting pipe through the fixed pipe and finally be discharged from the spray nozzle to achieve the dust reduction effect.

[0011] Preferably, an electric motor is installed on the side of the support box, and the output shaft of the motor is connected to a screw rod, and two sections of thread grooves in opposite directions are symmetrically arranged on the screw rod. At the same time, the screw rod and the piston plate are threadedly connected, and the piston plate and the fixed rod are slidingly connected. When the screw rod rotates, it can drive the two piston plates away from or closer to each other through the thread transmission with the piston plate.

[0012] Preferably, the edge of the piston plate fits and slides with the inner wall of the support box, and an infusion channel is provided on the inner top surface of the support box, and the support box is connected to the interior of the fixed tube through the infusion channel and the hose. The hose is fixed between the support box and the fixed tube below, and at the same time, the hose is connected to the fixed tube above through the infusion tube. When the two piston plates are close to each other, they can squeeze the liquid in the support box and transmit it to the hose and the infusion tube through the infusion channel.

[0013] Preferably, the protective mechanism includes a movable shaft rotatably arranged in the column, and the column is hollow inside, and the movable shaft is installed in the column through a vortex spring. At the same time, a protective net is wrapped around the outside of the movable shaft, and the edge of the protective net is fixed to the mounting plate. When the mounting plate is pulled, the protective net can be extended to perform multi-sided protection.

[0014] Preferably, the mounting plate is snap-fitted into the opening of the column, and a connecting plate is fixed to the bottom of the mounting plate. The connecting plate is an L-shaped structure, and the horizontal section of the connecting plate slides through a ground rod. After the mounting plate moves, the ground rod can be pushed downward into the ground, thereby ensuring the stability of the protective net after stretching.

[0015] Compared with the existing technology, the beneficial effects of the present invention are: the length of the rural road construction fence can be adjusted according to construction needs to achieve a wider range of enclosure, and it can also be used to fence the construction site on multiple sides, making the fence applicable to a wider range. At the same time, in the maintenance state, dust can be suppressed by spraying, thereby improving the construction environment. The specific contents are as follows: 1. Pulling one of the uprights causes the connecting rod to slide inside the horizontal column. The movement of the piston squeezes the gas inside the fixed chamber, allowing the gas to enter the lower connecting rod through the air inlet. The gas is then transmitted through the gas pipe to the upper fixed chamber, pushing the upper piston to move. In this way, pulling one of the uprights can drive the other upright in the opposite direction. The first and second fences move away from each other to increase the protection range. 2. Through the threaded transmission of the screw rod and the piston plate, the two piston plates are driven close to each other, squeezing the liquid in the support box and transmitting it to the hose through the infusion channel. The liquid then enters the fixed pipe below and can also be transmitted to the fixed pipe above through the infusion pipe. Finally, it enters the connecting pipe and is discharged from the spray nozzle to play the role of dust reduction. 3. Pull the mounting plate to separate it from the column, so that the protective net rolled up on the movable axis can be extended. After extension, it will be perpendicular to the fence. The construction site can be protected on three sides through the fence, and multi-sided maintenance can be achieved without using multiple fences. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-8 , the present invention provides the following technical solutions: Example 1: In order to solve the problems existing in the prior art, this embodiment adopts the following technical solutions: a rural road construction fence, including a support box 1, a movable wheel 2 is installed on the bottom of the support box 1 by bolts, and a first fence 3 and a second fence 4 are installed above the support box 1 respectively, the first fence 3 and the second fence 4 form a rectangular frame structure, and the first fence 3 and the second fence 4 are both composed of vertical columns 5 and horizontal columns 8, and the vertical columns 5 and the horizontal columns 8 are perpendicular to each other; it also includes: a boosting mechanism, which is arranged between the first fence 3 and the second fence 4, and the boosting mechanism realizes that the first fence 3 and the second fence 4 move in opposite directions; a dust reduction mechanism, which is arranged on the opposite side of the two horizontal columns 8, and the dust reduction mechanism is connected to the liquid inside the support box 1 to reduce dust by spraying; a protective mechanism, which is arranged inside the vertical column 5, and the protective mechanism is used to expand the protective area of the fence.

[0020] The existing construction fence has a limited enclosure area. When a larger range of maintenance is required, multiple fences need to be spliced together, which is inconvenient to operate and not convenient for the storage of the fence. Figure 1-Figure 3As shown, a support rod 15 is fixed to the bottom of the left column 5 and the bottom of the lower horizontal column 8, and a moving wheel 2 is installed at the bottom of the support rod 15, and a fixing rod 16 is fixed to the side of the support rod 15, and the fixing rod 16 slides through the support box 1; the boosting mechanism includes a connecting rod 6 fixed on the column 5, and the connecting rod 6 and the column 5 are perpendicular to each other, and the connecting rod 6 slides through the horizontal column 8, and a piston block 7 is fixed to the end of the connecting rod 6 away from the column 5; a fixing cavity 9 is opened in the horizontal column 8, and the edge of the piston block 7 slides in contact with the inner wall of the fixing cavity 9, the lower connecting rod 6 is hollow, and an air inlet 10 is reserved at the end of the connecting rod 6 close to 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 pipe 11, and the other end of the air pipe 11 is fixed to the upper horizontal column 8, and the lower connecting rod 6 is connected to the interior of the upper fixed cavity 9 through the air pipe 11; first, the construction fence is pushed to the designated position by the moving wheel 2 , the construction site can be directly protected by the first fence 3 and the second fence 4. When the protection range 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 in the fixed cavity 9. The piston block 7 squeezes the gas inside the fixed cavity 9, allowing the gas to enter the lower connecting rod 6 through the air inlet 10. The gas can then be transmitted to the upper fixed cavity 9 through the gas pipe 11 and push the upper piston block 7 to move. In this way, when one of the columns 5 is pulled, the other column 5 can be driven 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, and the fixed pipes 12 and connecting pipes 13 on the two columns 5 are staggered and separated, so that the columns 5 will not be affected when moving, and a protective effect can be achieved through the fixed pipes 12 and connecting pipes 13. When storing, you only need to push one of the columns 5 to automatically store the other column 5, which improves the convenience of operation.

[0021] Example 2: Since a large amount of dust will be generated during construction work at the construction site, the traditional construction fence lacks a structure to suppress the dust, which has a great impact on the construction environment. Therefore, this embodiment adopts the following technical solutions, such as Figure 6-Figure 8As shown, the dust reduction mechanism includes a fixed tube 12 fixed on the horizontal column 8, and connecting tubes 13 are arranged at equal intervals on the side of the fixed tube 12, and a spray nozzle 14 is arranged in the middle position of the connecting tube 13, and the two groups of fixed tubes 12 on the two horizontal columns 8 are staggered; an electric motor 17 is installed on the side of the support box 1, and the output shaft of the motor 17 is connected to a screw rod 18, and two sections of thread grooves in opposite directions are symmetrically provided on the screw rod 18, and the screw rod 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 fits and slides with the inner wall of the support box 1, and an infusion channel 20 is provided on the inner top surface of the support box 1, and the support box 1 is connected to the inside of the fixed tube 12 through the infusion channel 20 and the hose 21, and the hose 21 is fixed to the support box 1 and the fixed The first and second fences 3 and 4 are deployed and used, so 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 screw rod 18 to rotate, and the two piston plates 19 are driven close to each other through the threaded transmission of the screw rod 18 and the piston plate 19. The liquid in the support box 1 is squeezed, so that the liquid is transmitted to the hose 21 through the infusion channel 20, and then the liquid enters the fixed pipe 12 below. It can also be transmitted to the fixed pipe 12 above through the infusion pipe 22, and finally enters the connecting pipe 13 and is discharged from the spray nozzle 14 to play a role in dust reduction. 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, thereby improving the dust reduction effect.

[0022] Example 3: Since the construction site is not blocked on one side when it is fenced, and the traditional construction fence is not convenient for blocking multiple sides at the same time, it still requires multiple fences to be spliced together, so this embodiment adopts the following technical solutions, such as Figure 4-Figure 5 As shown, the protective mechanism includes a movable shaft 23 rotatably set in the column 5, and the column 5 is hollow, and the movable shaft 23 is installed in the column 5 through a vortex spring, and at the same time, a protective net 24 is wrapped around the outer side of the movable shaft 23, and the edge of the protective net 24 is fixed to the mounting plate 25; the mounting plate 25 is snap-fitted at the opening of the column 5, and a connecting plate 26 is fixed to the bottom of the mounting plate 25, and the connecting plate 26 is an "L"-shaped structure, and the horizontal section of the connecting plate 26 is slidably penetrated by a ground-inserting rod 27; when the construction site requires multi-faceted maintenance, the mounting plate 25 can be pulled to separate it from the column 5, so that the protective net 24 rolled up on the movable shaft 23 can be extended, and after extension, it is perpendicular to the fence, and the construction site is protected on three sides by the fence. After moving, the ground-inserting rod 27 is pushed into the ground to ensure 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 reeled up by the resilience of the vortex spring.

[0023] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
