Description

Technical Field

[0001] This utility model belongs to the field of construction site enclosure technology, specifically relating to a safety enclosure for highway construction. Background Technology

[0002] During road construction, safety barriers are required to protect the construction site and ensure the safety of vehicles and pedestrians.

[0003] Traditional construction site fencing is mostly a monolithic panel structure or a bulky water-filled barrier. Its fixed shape results in a huge space occupation during transportation and storage, significantly increasing logistics costs. Secondly, existing fencing units usually use rigid connections or simple hinged joints. When the construction route needs to be laid along curved roads, this connection method makes it difficult for the fencing array to turn smoothly, often forming sharp angles or large gaps at the turning points. This not only disrupts the continuity of the protective barrier and weakens its guiding and warning effects, but also constitutes a significant safety hazard. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a safety barrier for highway construction, which solves the problem that traditional barriers, due to their rigid structure and rudimentary connection methods, not only lead to high transportation and storage costs, but also create serious safety shortcomings when laid out on curves because they cannot be smoothly transitioned.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a safety enclosure for highway construction, comprising a support assembly, wherein two sets of the support assembly are mirror-arranged, and a first baffle and a second baffle are rotatably arranged on both sides of the support assembly, the first baffle and the adjacent second baffle are hinged together. The support assembly includes a fixed rod, a first mounting plate, a second mounting plate, a connecting rod, a third mounting plate, and a threaded rod. The first mounting plate is fixedly mounted at the top of the fixed rod, and a threaded rod is fixedly mounted at the center of the top surface of the first mounting plate. The second mounting plate is fixedly mounted on the top surface of the threaded rod, and a connecting rod is fixedly mounted at the center of the top surface of the second mounting plate, and a third mounting plate is fixedly mounted at the top of the connecting rod. Both ends of the third mounting plate are... A movable rod is rotatably mounted throughout the structure, and the bottom ends of two sets of movable rods are respectively connected to baffle one and baffle two positioned on corresponding positions on both sides of the support assembly. A rotating block is fixed at the top of each movable rod, and a limit insertion hole is provided on the top surface of the rotating block. The limit insertion hole is connected to an adjustment assembly, which includes a plug rod that fits into the limit insertion hole. The plug rod is fixed to the bottom surface of the pressure plate, and the pressure plate is connected to guide rod one. Guide rod one is connected to the top end of a sliding cylinder slidably mounted on the outside of the connecting rod. Guide rod two is fixed at the bottom end of the sliding cylinder, and guide rod two is connected to a limit plate. The limit plate is rotatably mounted on the top surface of an internally threaded cylinder, and the internally threaded cylinder is sleeved on the outside of the threaded rod and threadedly connected to it.

[0006] The beneficial effects of this utility model are:

[0007] The coordinated action of the adjusting component and the rotating block allows the insert rod to be precisely inserted into or disengaged from the limiting holes at different positions on the rotating block by rotating the internal threaded cylinder. This enables construction workers to quickly and easily unlock the first and second baffles with one hand without any tools, rotate them to any desired angle, and then securely lock them again. This allows the fence to perfectly conform to curves of different curvatures, forming a continuous and smooth guide line. At the same time, by operating the adjusting component to unlock the baffles, the first and second baffles on both sides can be rotated inward and folded together, minimizing the width of the entire fence unit and giving the fence an efficient folding and storage function.

[0008] To provide guidance and balance for the vertical movement of the pressure plate and the slide:

[0009] As a further improvement to the above technical solution: both guide rod one and guide rod two are provided in two sets, and the two sets of guide rod one are symmetrically arranged on both sides of the top surface of the pressure plate, and the two sets of guide rod two are symmetrically arranged on both sides of the bottom surface of the pressure plate. The guide rod one and guide rod two respectively penetrate the mounting plate three and the mounting plate two and are slidably connected to them.

[0010] The beneficial effects of this improvement are: guide rod one and guide rod two provide guidance and balance for the vertical movement of the pressure plate and the slide cylinder, effectively preventing the pressure plate from tilting or jamming, and ensuring that the insertion rod can be accurately aligned and inserted into the limiting insertion hole.

[0011] To prevent the limit plate and guide rod two from rotating together, and to ensure that only vertical translation occurs:

[0012] As a further improvement to the above technical solution: the limiting plate is rotatably mounted on the top surface of the internal threaded cylinder via a bearing, and a movable through hole is provided through the center of the limiting plate, the threaded rod passes through the movable through hole, and the inner diameter of the movable through hole is not less than the diameter of the threaded rod.

[0013] The beneficial effect of this improvement is that the limiting plate is rotatably set on the top surface of the internal threaded cylinder by the bearing, so that when the construction personnel rotate the internal threaded cylinder, the limiting plate and the guide rod 2 will not rotate together, but only move up and down.

[0014] To enhance the adaptability and functionality of the construction site fencing:

[0015] As a further improvement to the above technical solution: the top surface of the rotating block is provided with several sets of limiting holes equidistantly arranged around the center line.

[0016] The beneficial effects of this improvement are as follows: Several sets of limiting holes provide multiple fixed locking positions for the unfolding angle of baffle one and baffle two. Construction personnel can precisely lock baffle one and baffle two at multiple specific angles according to different road diversion needs or site restrictions, thereby meeting diverse deployment requirements and enhancing the adaptability and functionality of the enclosure.

[0017] To provide construction workers with an intuitive visual reference:

[0018] As a further improvement to the above technical solution: the side of the rotating block is provided with an angle scale value, and the mounting plate is fixedly provided with a pointer for indicating the scale value.

[0019] The beneficial effects of this improvement are: setting angle scale values ​​on the side of the rotating block, and cooperating with the pointer on the mounting plate three, provides construction personnel with an intuitive visual reference.

[0020] To ensure the fencing is securely installed on the ground:

[0021] As a further improvement to the above technical solution: both the bottom ends of the baffle and the fixing rod are fixed with fixing plates, and mounting holes are opened through both sides of the fixing plates.

[0022] The beneficial effect of this improvement is that the fence can be firmly installed on the ground by passing fasteners such as anchor bolts through the mounting holes.

[0023] In summary, the beneficial effects of this case are as follows:

[0024] The coordinated action of the adjusting component and the rotating block allows the insert rod to be precisely inserted into or disengaged from the limiting holes at different positions on the rotating block by rotating the internal threaded cylinder. This enables construction workers to quickly and easily unlock the first and second baffles with one hand without any tools, rotate them to any desired angle, and then securely lock them again. This allows the fence to perfectly conform to curves of different curvatures, forming a continuous and smooth guide line. At the same time, by operating the adjusting component to unlock the baffles, the first and second baffles on both sides can be rotated inward and folded together, minimizing the width of the entire fence unit and giving the fence an efficient folding and storage function.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0035] like Figure 1-7As shown, a safety enclosure for highway construction includes a support assembly 1. Two sets of the support assembly 1 are mirror-arranged. A first baffle 2 and a second baffle 3 are rotatably mounted on both sides of the support assembly 1. The first baffle 2 is hinged to the adjacent second baffle 3. The support assembly 1 includes a fixed rod 5, a mounting plate 1 6, a mounting plate 2 7, a connecting rod 8, a mounting plate 3 9, and a threaded rod 12. The first mounting plate 6 is fixed to the top of the fixed rod 5, and the threaded rod 12 is fixed to the center of the top surface of the mounting plate 1 6. The second mounting plate 7 is fixed to the top surface of the threaded rod 12. The connecting rod 8 is fixed to the center of the top surface of the mounting plate 2 7, and the third mounting plate 9 is fixed to the top of the connecting rod 8. Movable rods are rotatably mounted through both ends of the third mounting plate 9, and the bottom ends of the two sets of movable rods are respectively connected to the support... The support assembly 1 has baffles 2 and 3 at corresponding positions on both sides. The top of each movable rod is fixed with a rotating block 10. The top surface of the rotating block 10 is provided with a limiting insertion hole 11. The limiting insertion hole 11 is connected to the adjustment assembly 4. The adjustment assembly 4 includes a plug rod 407 that is fitted and connected to the limiting insertion hole 11. The plug rod 407 is fixed to the bottom surface of the pressure plate 402. The pressure plate 402 is connected to a guide rod 403. The guide rod 403 is connected to the top of the sliding cylinder 401 outside the connecting rod 8. The bottom end of the sliding cylinder 401 is fixed with a guide rod 406. The guide rod 406 is connected to a limiting plate 405. The limiting plate 405 is rotatably disposed on the top surface of the internal threaded cylinder 404. The internal threaded cylinder 404 is sleeved on the outside of the threaded rod 12 and threadedly connected to it.

[0036] Two sets of guide rods 403 and 406 are provided, with the two sets of guide rods 403 symmetrically arranged on both sides of the top surface of the pressure plate 402, and the two sets of guide rods 406 symmetrically arranged on both sides of the bottom surface of the pressure plate 402. The guide rods 403 and 406 pass through the mounting plate 9 and the mounting plate 7 respectively and are slidably connected to them. The guide rods 403 and 406 provide guidance and balance for the vertical movement of the pressure plate 402 and the slide cylinder 401, effectively preventing the pressure plate 402 from tilting or getting stuck, and ensuring that the insertion rod 407 can be accurately aligned and inserted into the limiting insertion hole 11.

[0037] The limiting plate 405 is rotatably mounted on the top surface of the internal threaded cylinder 404 via a bearing, and a movable through hole is provided through the center of the limiting plate 405. The threaded rod 12 passes through the movable through hole, and the inner diameter of the movable through hole is not less than the diameter of the threaded rod 12. The limiting plate 405 is rotatably mounted on the top surface of the internal threaded cylinder 404 via the bearing, so that when the construction personnel rotate the internal threaded cylinder 404, the limiting plate 405 and the guide rod 406 will not rotate together, but only move up and down.

[0038] The top surface of the rotating block 10 is provided with several sets of limiting holes 11 equidistantly arranged around the center line; the several sets of limiting holes 11 provide multiple fixed locking positions for the unfolding angle of the first baffle 2 and the second baffle 3. Construction personnel can precisely lock the first baffle 2 and the second baffle 3 at multiple specific angles according to different road diversion needs or site restrictions, thereby meeting diverse layout requirements and enhancing the adaptability and functionality of the enclosure.

[0039] The rotating block 10 has an angle scale on its side, and the mounting plate 3 9 is fixed with a pointer for indicating the scale value. The angle scale on the side of the rotating block 10, together with the pointer on the mounting plate 3 9, provides an intuitive visual reference for construction personnel.

[0040] The bottom ends of both the baffle 2 and the fixing rod 5 are fixed with fixing plates, and mounting holes are opened through both sides of the fixing plates; by passing fasteners such as anchor bolts through the mounting holes, the fence can be firmly installed on the ground.

[0041] The working principle and usage process of this utility model are as follows: During transportation or storage, the fencing unit is in a retracted state. By rotating the internal threaded cylinder 404, the sliding cylinder 401 is driven to move the pressure plate 402 upward, causing the insertion rod 407 to be pulled out from the limiting insertion hole 11 of the rotating block 10. At this time, the locking of the first baffle 2 and the second baffle 3 is released, and the construction personnel can rotate the first baffle 2 and the second baffle 3 on both sides inward to make them retract towards the support component 1, which greatly reduces the overall width of the fencing unit. This allows more fencing units to be stacked side by side on the truck, significantly saving transportation space and storage space. After arriving at the construction site, the construction personnel place the retracted fencing unit in the predetermined position. First, rotate the first baffle 2 and the second baffle 3 outward to approximately the required angle. Then, rotate the internal threaded cylinder... 404. This allows the pressure plate 402 and the insertion rod 407 to descend smoothly. During this process, guide rod 1 403 and guide rod 2 406 ensure the verticality and stability of the downward path, preventing the insertion rod 407 from deviating. When the insertion rod 407 is inserted into the corresponding limit hole 11 on the rotating block 10, the angle of the baffle is firmly locked. If there are curves in the construction route and the guide angle of the fence needs to be precisely adjusted, the construction personnel can unlock it again through the above operation. At this time, the scale value on the side of the rotating block 10 can be observed, and with the pointer on the mounting plate 3 9, the baffle can be precisely adjusted to the target angle and then locked again. Finally, by passing bolts and other fasteners through the mounting holes on the bottom fixing plate of the fixing rod 5, the entire fence array is firmly fixed to the ground to resist wind and accidental collisions.
