Description

Technical Field

[0001] This application relates to the field of engineering construction safety protection technology, specifically a project operation safety protection device. Background Technology

[0002] At project sites, especially construction sites, safety guardrails and protective nets are widely used to isolate dangerous areas such as openings, edges, and high-altitude work areas to prevent people and objects from falling and to ensure construction safety.

[0003] Currently, most mature safety protection devices in the industry are based on a "support rod + protective frame + protective net" structure. The support rod serves as the main support and is fixed at the edge of the dangerous area. The protective frame and the protective net form an isolation unit, which is assembled with the support rod through bolt connection, snap-fit, or plug-in connection.

[0004] Chinese utility model patent CN219910095U discloses a safety protection device for engineering operations. It features connecting grooves on both sides of a support rod, with the protective frame and connecting frame movably embedded in these grooves via connecting plates. The device utilizes the cooperation of a locking pin and a groove, and a rotating rod and a positioning hole, to achieve rapid connection and disassembly of the support rod, protective frame, and connecting frame, solving the problem of cumbersome traditional bolt connections. A sliding connecting frame is installed at one end of the protective frame, slidably connected to the upper and lower ends of the protective frame via a connecting rod. A protective net is built inside the protective frame and connecting frame. The sliding connecting frame allows for the stretching or folding of the protective net, flexibly adjusting the protection range to suit hazardous areas of varying widths.

[0005] However, because the locking structure of this patent is fixed on both sides of the support rod, the protective frame and the connecting frame can only be connected by the connecting plate being embedded in the connecting groove on both sides of the support rod. This means that adjacent protective frames can only be arranged along the straight line of the support rod, and the included angle between adjacent protective frames cannot be adjusted according to the actual needs of the construction site (such as the elevator shaft opening at a right angle). For example, in the scenario of edge protection at the corner of a floor, if 90° corner protection is required, this device needs to add additional support rods and adjust the arrangement of protective frames, which not only increases material costs, but may also create protective gaps due to installation errors of multiple support rods.

[0006] Therefore, this application provides a project operation safety protection device to solve the above problems. Utility Model Content

[0007] This application provides a project operation safety protection device, which aims to solve the problems mentioned in the background art, such as the inability to adjust the included angle between adjacent protection units of existing safety protection devices, and the inability to meet the protection needs of complex areas with right-angle turns.

[0008] To achieve the above objectives, this application provides the following technical solution: a project operation safety protection device, comprising support rods arranged opposite each other, a fence assembly disposed between adjacent support rods, and an assembly mechanism for assembling the fence assembly and the support rods; the assembly mechanism includes a fixed insert plate fixedly sleeved on the top and bottom of the support rods, a movable insert plate sleeved on the fixed insert plate and rotatably connected to the support rods, and a fixed sleeve fixedly connected to both ends of the fence assembly for adaptation to the movable insert plate and the fixed insert plate, respectively. A handle bolt penetrating the movable insert plate or the fixed insert plate is inserted into the fixed sleeve, and a nut for thread adaptation to the handle bolt is fixedly connected to the bottom of the fixed sleeve. During assembly, the fixed insert plate or the movable insert plate on the support rod is inserted into the fixed sleeve of the fence assembly, and then the handle bolt is inserted through the fixed sleeve and the movable insert plate or the fixed insert plate, with the bottom of the handle bolt threadedly connected to the nut, thus completing the assembly and fixation of the fence assembly and the support rods. Since the fixed plate is fixed to the support rod, the movable plate can rotate around the support rod. When the movable plate is rotated, the angle between it and the fixed plate changes, which in turn drives the fence components connected to the fixed plate and the movable plate to change the angle, thereby realizing the angle adjustment of adjacent fence components.

[0009] Preferably, the movable insert plate has a Y-shaped structure, with its end near the support rod having a U-shaped opening, and the fixed insert plate is located within the opening of the movable insert plate. This ensures spatial compatibility between the movable and fixed insert plates, preventing interference with the rotation of the movable insert plate around the support rod while maintaining a stable connection with the fixed sleeve, thus ensuring the stability of the assembled structure during angle adjustment.

[0010] Preferably, to facilitate the connection of the handle bolt through the fixed sleeve and fixed or movable insert plate to the nut, the fixed sleeve, fixed insert plate, and movable insert plate are all provided with through holes for fitting the handle bolt. This provides a precise insertion channel for the handle bolt, ensuring that the handle bolt can smoothly pass through all three, achieving a stable threaded connection and avoiding assembly difficulties or loosening due to misaligned holes.

[0011] Preferably, to facilitate the insertion of the fixed or movable insert plate into the fixed sleeve, both ends of the fixed and movable insert plates away from the support rod are provided with rounded corners. This reduces the resistance when the fixed or movable insert plate is inserted into the fixed sleeve, prevents the edges of the insert plates from colliding and wearing against the inner wall of the fixed sleeve, improves assembly convenience, and extends the service life of the components.

[0012] Preferably, to facilitate the rotation of the movable insert plate on the support rod: the support rod is a hollow cylindrical structure, and the movable insert plate has a circular hole for fitting with the support rod, thus adapting to the rotation requirements of the movable insert plate.

[0013] Preferably, to reduce wear between the circular hole and the support rod, the movable insert plate is connected to the support rod via a bearing. This converts the sliding friction between the movable insert plate and the support rod into rolling friction, significantly reducing wear on both and decreasing resistance during rotation of the movable insert plate, making angle adjustment easier and smoother.

[0014] Preferably, to facilitate the adaptation of the fence assembly to the spacing between adjacent support rods: the fence assembly includes a first frame plate and a second frame plate slidably inserted into one end of the first frame plate. Protective netting is fixedly connected to both the first and second frame plates, and a fixing sleeve is fixedly connected to the opposite ends of the first and second frame plates. This allows for flexible adjustment of the overall length of the fence assembly to accommodate different spacings between adjacent support rods, eliminating the need to replace fences of different sizes and improving the versatility and adaptability of the device to various scenarios.

[0015] Preferably, a U-shaped bracket is fixedly connected to the bottom of the support rod, and a rubber column is fixedly connected to the bottom of the U-shaped bracket. This increases the contact area between the support rod and the ground, improving the support stability of the support rod. At the same time, the rubber column can play a role in preventing slippage and shock absorption, preventing the support rod from sliding or its bottom from wearing down.

[0016] Preferably, to facilitate locking the relative position of the movable insert plate and the support rod: a support plate is fixedly connected to the top of the movable insert plate, and a knurled bolt for contacting the support rod is threaded onto the support plate. This allows for quick locking of the relative position of the movable insert plate and the support rod, ensuring that the movable insert plate does not shift after being adjusted to the target angle, guaranteeing the stability of the included angle between adjacent fence components, and improving the structural reliability of the protective device.

[0017] This application enables the rapid assembly and disassembly of fence components and support rods through the fixed connection between the fixed insert plate and the support rod, as well as the rotatable connection between the movable insert plate and the support rod. It also allows for flexible adjustment of the included angle between adjacent fence components, adapting to the protection needs of irregular dangerous areas (such as corners) on construction sites, while balancing assembly efficiency and scene adaptability.

[0018] This application utilizes the cooperation of a support plate and knurled bolts to quickly lock the relative position of the movable insert plate and the support rod, ensuring that the movable insert plate does not shift after being adjusted to the target angle, thus guaranteeing the stability of the included angle between adjacent fence components and improving the structural reliability of the protective device.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Example 1 This embodiment provides a project operation safety protection device, such as... Figure 1-3 As shown, the protective device includes support rods 1 arranged opposite each other, fence components 2 arranged between adjacent support rods 1, and an assembly mechanism 3 for assembling the fence components 2 with the support rods 1. The assembly mechanism 3 includes fixed insert plates 31 fixedly sleeved on the top and bottom of the support rods 1, movable insert plates 32 sleeved on the fixed insert plates 31 and rotatably connected to the support rods 1, and fixed sleeves 33 fixedly connected to both ends of the fence components 2 for fitting with the movable insert plates 32 and the fixed insert plates 31, respectively. A handle bolt 34 penetrating the movable insert plate 32 or the fixed insert plate 31 is inserted into the fixed sleeve 33, and a nut 35 for thread fitting with the handle bolt 34 is fixedly connected to the bottom of the fixed sleeve 33. Through the fixed connection between the fixed insert plates 31 and the support rods 1 and the rotatable connection between the movable insert plates 32 and the support rods 1, the fence components 2 and the support rods 1 can be quickly assembled and disassembled. At the same time, the included angle between adjacent fence components 2 can be flexibly adjusted to adapt to the protection needs of irregular dangerous areas (such as corners) on the construction site, taking into account both assembly efficiency and scene adaptability. During assembly, the fixed insert plate 31 or movable insert plate 32 on the support rod 1 is inserted into the fixed sleeve 33 of the fence assembly 2. Then, the handle bolt 34 is inserted through the fixed sleeve 33 and the movable insert plate 32 or the fixed insert plate 31, and the bottom of the handle bolt 34 is threadedly connected to the nut 35, thus completing the assembly and fixation of the fence assembly 2 and the support rod 1. Since the fixed insert plate 31 is fixed to the support rod 1, the movable insert plate 32 can rotate around the support rod 1. When the movable insert plate 32 is rotated, the angle between it and the fixed insert plate 31 changes, thereby causing the fence assemblies 2 connected to the fixed insert plate 31 and the movable insert plate 32 to change their angles, thus realizing the angle adjustment of adjacent fence assemblies 2.

[0023] The movable insert plate 32 has a Y-shaped structure, with its end near the support rod 1 having a U-shaped opening. The fixed insert plate 31 is located inside the opening of the movable insert plate 32. This design ensures spatial compatibility between the movable insert plate 32 and the fixed insert plate 31, preventing interference with the rotation of the movable insert plate 32 around the support rod 1 while maintaining a stable connection with the fixed sleeve 33, thus ensuring the stability of the assembled structure during angle adjustment. When the movable insert plate 32 rotates around the support rod 1, the opening structure avoids the fixed insert plate 31, preventing collisions and interference, while also maintaining the structural integrity of the movable insert plate 32 during rotation and ensuring the connection accuracy with the fixed sleeve 33.

[0024] To facilitate the connection of the handle bolt 34 through the fixed sleeve 33 and fixed insert plate 31 or movable insert plate 32 to the nut 35, through holes are provided on the fixed sleeve 33, fixed insert plate 31, and movable insert plate 32 to fit the handle bolt 34. This provides a precise insertion channel for the handle bolt 34, ensuring it can smoothly pass through all three, achieving a stable threaded connection and preventing assembly difficulties or loosening due to misaligned holes. When assembling the fence component 2 and the support rod 1, the through hole of the fixed sleeve 33 should be aligned with the through hole of the fixed insert plate 31 or the movable insert plate 32 so that the handle bolt 34 can pass through the fixed sleeve 33 and the fixed insert plate 31 (or the movable insert plate 32) in sequence along the through hole, and finally be screwed into the nut 35 at the bottom of the fixed sleeve 33. The size of the through hole is adapted to the handle bolt 34, which not only ensures that the handle bolt 34 is installed smoothly, but also restricts the relative wobbling of the three, and ensures that the connection between the fixed sleeve 33 and the fixed insert plate 31 (or the movable insert plate 32) is stable after assembly.

[0025] To facilitate the insertion of the fixed insert plate 31 or the movable insert plate 32 into the fixed sleeve 33, both ends of the fixed insert plate 31 and the movable insert plate 32 away from the support rod 1 are provided with rounded corners. This reduces the resistance when the fixed insert plate 31 or the movable insert plate 32 is inserted into the fixed sleeve 33, avoids the edges of the insert plates from colliding and wearing with the inner wall of the fixed sleeve 33, improves the ease of assembly, and extends the service life of the components. When it is necessary to insert the fixed insert plate 31 or the movable insert plate 32 into the fixed sleeve 33, the two sides of the insert plate away from the support rod 1 are rounded corners (instead of right angles). The rounded corners can guide the insert plate to smoothly enter the opening of the fixed sleeve 33, reducing the frictional resistance between the edge of the insert plate and the inner wall of the fixed sleeve 33.

[0026] To facilitate the rotation of the movable insert plate 32 on the support rod 1: the support rod 1 is a hollow cylindrical structure, and the movable insert plate 32 has a circular hole for fitting with the support rod 1. This accommodates the rotational requirements of the movable insert plate 32. The circular hole on the movable insert plate 32 precisely matches the cylindrical shape of the support rod 1, allowing the movable insert plate 32 to rotate smoothly around the axis of the support rod 1.

[0027] To reduce wear between the circular hole and the support rod 1, the movable insert plate 32 is connected to the support rod 1 via a bearing. This converts the sliding friction between the movable insert plate 32 and the support rod 1 into rolling friction, significantly reducing wear on both and decreasing resistance during rotation, making angle adjustment easier and smoother. The bearing is installed between the circular hole of the movable insert plate 32 and the support rod 1. When the movable insert plate 32 rotates around the support rod 1, the inner ring of the bearing remains relatively stationary with the support rod 1 (fixed), while the outer ring rotates synchronously with the movable insert plate 32 (rotating). The rolling elements (such as steel balls) inside the bearing roll between the inner and outer rings, replacing the direct sliding contact between the circular hole of the movable insert plate 32 and the outer wall of the support rod 1. This rolling friction method not only significantly reduces rotational resistance, making angle adjustment easier for operators, but also avoids wear caused by direct friction, extending the service life of both the movable insert plate 32 and the support rod 1.

[0028] To facilitate the adaptation of the fence assembly 2 to the spacing between adjacent support rods 1, the fence assembly 2 includes a first frame plate 21 and a second frame plate 22 slidably inserted into one end of the first frame plate 21. Protective netting 23 is fixedly connected to both the first frame plate 21 and the second frame plate 22. A fixing sleeve 33 is fixedly connected to the opposite ends of the first frame plate 21 and the second frame plate 22. The overall length of the fence assembly 2 can be flexibly adjusted to adapt to different spacings between adjacent support rods 1, eliminating the need to replace fences of different sizes and improving the versatility and adaptability of the device to various scenarios. The first frame plate 21 and the second frame plate 22 of the fence assembly 2 are slidably connected. The second frame plate 22 can slide and extend along one end of the first frame plate 21, thereby changing the overall length of the fence assembly 2. When the distance between two adjacent support rods 1 changes, the operator can push the second frame plate 22 to extend or retract relative to the first frame plate 21 until the length of the fence assembly 2 matches the distance between the two support rods 1. At the same time, a protective net 23 is fixed on both the first frame plate 21 and the second frame plate 22. The protective net 23 expands or retracts synchronously with the extension and retraction of the frame plate, always maintaining a complete protective barrier and ensuring that the protective effect is not interrupted.

[0029] The first frame plate 21 has a bolt threaded into one end near the second frame plate 22 for contacting the second frame plate 22.

[0030] A U-shaped bracket 11 is fixedly connected to the bottom of the support rod 1, and a rubber column 12 is fixedly connected to the bottom of the U-shaped bracket 11. This increases the contact area between the support rod 1 and the ground, improving the support stability of the support rod 1. Simultaneously, the rubber column 12 provides anti-slip and shock absorption, preventing the support rod 1 from sliding or its bottom from wearing down. The U-shaped bracket 11 fixed to the bottom of the support rod 1 has a contact area with the ground that is much larger than the cross-sectional area of ​​the support rod 1 itself. This disperses the pressure of the support rod 1 on the ground, preventing the support rod 1 from sinking into soft ground due to concentrated force, and also enhances the horizontal anti-tipping ability of the support rod 1. The rubber column 12 at the bottom of the U-shaped bracket 11 is in direct contact with the ground; the rubber material has a high coefficient of friction, increasing the friction between the U-shaped bracket 11 and the ground, preventing the support rod 1 from accidentally sliding during construction.

[0031] Example 2 Unlike Embodiment 1, to facilitate locking the relative position of the movable insert plate 32 and the support rod 1, a support plate 4 is fixedly connected to the top of the movable insert plate 32, and a knurled bolt 41 for contacting the support rod 1 is threaded onto the support plate 4. This allows for quick locking of the relative position of the movable insert plate 32 and the support rod 1, ensuring that the movable insert plate 32 does not shift after being adjusted to the target angle, guaranteeing the stability of the included angle between adjacent fence components 2, and improving the structural reliability of the protective device. The support plate 4 fixed to the top of the movable insert plate 32 has a threaded hole, and the knurled bolt 41 is threaded into the threaded hole. When the movable insert plate 32 rotates around the support rod 1 to the required angle, the operator can rotate the knurled bolt 41 clockwise. Since the knurled bolt 41 is threaded with the support plate 4, the knurled bolt 41 will advance along the threaded hole until its bottom end is in close contact with the outer wall of the support rod 1. At this time, the static friction between the knurled bolt 41 and the support rod 1 will restrict the rotation of the movable insert plate 32 and lock the relative position of the movable insert plate 32 and the support rod 1. If the angle needs to be adjusted again, simply rotate the knurled bolt 41 counterclockwise to disengage its bottom end from the outer wall of the support rod 1 to release the lock. The operation is convenient and efficient.

[0032] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
