[0041] Example 1

[0042] like Figures 1 to 12 As shown in the figure, this embodiment describes in detail a construction enclosure for an airport runway project.

[0043] The construction enclosure for the airport runway project includes a baffle 1, which consists of a frame and a panel. Multiple reinforcing strips 3 are evenly distributed on the frame to enhance the overall strength and stability of the baffle 1. Adjusting pipes 2 are fixedly connected to both ends of the baffle 1 along its length. A keyway is provided inside the adjusting pipe 2 along its axis. An adjusting rod 11 is slidably connected inside the keyway. The outer end of the adjusting rod 11 is provided with key teeth that cooperate with the keyway inside the adjusting pipe 2. The bottom end of the adjusting rod 11 is rounded and contacts the top of the wedge block 10.

[0044] A fixed block 3 is fixedly connected to one end of the baffle 1 along its length. A rotating shaft 4 is fixedly connected to the fixed block 3. A rotating bracket 5 is connected to the outer end of the rotating shaft 4 by a rotating connection. A transverse bracket 6 is fixedly connected to the outer end of the rotating bracket 5. The transverse bracket 6 provides support when the baffle 1 needs to be unfolded.

[0045] A slider 7 is slidably connected to the bottom of the baffle 1. The slider 7 is rotatably connected to the transverse support 6 via a connecting rod 8. A guide rod 9 is fixedly connected to the end of the slider 7 near the rotating support 5. A wedge 10 is fixedly connected to the top end of the guide rod 9 away from the slider 7. A through hole is provided on the baffle 1 at the position corresponding to the guide rod 9 and the wedge 10. When the transverse support 6 is perpendicular to the baffle 1, the guide rod 9 can penetrate the baffle 1 and extend to the outside of the baffle 1. The extension distance is equal to the distance from the end of the adjusting tube 2 away from the baffle 1 to the baffle 1.

[0046] The slider 7 is fixedly connected with a guide rod two 12 away from one end of the guide rod one 9. The outer wall of the guide rod two 12 is sleeved with a spring 13, the spring 13 is abutted with the slider 7 at one end, and the spring 13 is always in a compressed state, ensuring that the horizontal support 6 can be smoothly operated during folding and unfolding.

[0047] Working principle

[0048] In use, first, place one fence in the appropriate position, then align the adjusting pipe 2 of the other fence with the adjusting pipe 2 of the first fence, insert the adjusting rod 11 on the aligned adjusting pipe 2, adjust the angle between the two baffles 1 by rotating the baffle 1, at this time, the key teeth of the adjusting rod 11 are located in the adjusting pipe 2 on the first fence, the adjusting pipes 2 of the two fences can rotate freely around the middle adjusting rod 11, and the angle is flexibly adjusted.

[0049] After the angle adjustment is completed, manually pull the horizontal support 6 away from one end of the rotating support 5, so that the horizontal support 6 and the rotating support 5 rotate around the rotating shaft 4, at this time, the spring 13 drives the guide rod two 12, the slider 7, the guide rod one 9 and the wedge block 10 to move along the guide rod two 12 in the direction pointing to the guide rod one 9, the slider 7 pushes the horizontal support 6 to rotate through the connecting rod 8, so that the horizontal support 6 is popped out until the horizontal support 6 is perpendicular to the baffle 1, the horizontal support 6 is unfolded to effectively support the baffle 1, ensuring the stability and safety of the fence.

[0050] The baffle 1 is composed of a frame and a panel, and is provided with a plurality of reinforcing strips 3, which enhances the overall strength and durability of the fence, and meets the construction needs of complex environments in airport runway engineering.

[0051] The design of the adjusting pipe 2 and the adjusting rod 11 allows the angle between the two fences to be freely adjusted, meeting the needs of different construction scenes.

[0052] By manually pulling the horizontal support 6, the horizontal support is quickly unfolded and locked, without the need for complex tools or mechanical equipment, which is convenient for construction personnel to operate.

[0053] The slider 7 and the horizontal support 6 are self-locked through the connecting rod 8, ensuring that the horizontal support 6 will not accidentally rotate after unfolding, improving the safety of the fence.

[0054] The guide rod one 9 cooperates with the key groove in the adjusting pipe 2, and through the interaction of the wedge block 10 and the adjusting rod 11, the baffles are stably locked, preventing the fence from loosening or mispositioning due to external forces during construction.

[0055] The design of the adjusting rod 11 makes the installation and disassembly process of the fence simple and fast, saving construction time and labor cost.

[0056] This embodiment provides a robust, flexible, and easy-to-operate construction fence for airport runway engineering, which can effectively improve the safety and work efficiency of the construction site.

[0057] Example 2

[0058] like Figures 1 to 12 As shown, based on Example 1, in addition to the baffle 1, adjusting pipe 2, fixing block 3, rotating shaft 4, rotating bracket 5, transverse bracket 6, slider 7, connecting rod 8, guide rod 9, wedge block 10, and adjusting rod 11, the airport runway construction enclosure also includes the following structure:

[0059] Spring 13 passes through the reinforcing bar 3 near the pivot 4, ensuring that spring 13 is always in a compressed state. The end of spring 13 away from slider 7 abuts against the reinforcing bar 3, which improves the stability and durability of spring 13.

[0060] A diagonal brace 14 is fixedly connected to the outer end of the rotating bracket 5 near its top. The end of the diagonal brace 14 away from the rotating bracket 5 is fixedly connected to the transverse bracket 6. The connection point between the diagonal brace 14 and the transverse bracket 6 is located between the connection point of the transverse bracket 6 and the connecting rod 8 and the rotating bracket 5, which enhances the support strength and structural stability of the transverse bracket 6 after it is deployed.

[0061] Spring 13 is always in a compressed state, ensuring that when the transverse support 6 rotates around the pivot 4 to be perpendicular to the baffle 1, the angle between the connecting rod 8 and the vertical line of the axis of the guide rod 9 is less than 16.7 degrees.

[0062] The static friction coefficient between slider 7 and baffle 1 is not less than 0.3, ensuring that the transverse support 6 can be firmly attached to the outer end of baffle 1 after folding.

[0063] When the transverse support 6 is attached to the baffle 1, the connection point between the transverse support 6 and the connecting rod 8 is located between the axis of the baffle 1 and the guide rod 12, so that the transverse support 6 will not pop out due to external force after it is attached to the baffle 1, thus ensuring the safety of the enclosure.

[0064] The regulating tube 2 is composed of multiple regulating sections. The key teeth at the outer end of the regulating rod 11 are intermittently arranged. The length of the key teeth does not exceed the length of the regulating section, and there is at least one regulating section distance between two regulating sections.

[0065] This design allows each key tooth to engage with two adjustment sections, enabling locking and unlocking of the adjustment sections, providing more angle adjustment options, and enhancing the flexibility and adaptability of the enclosure.

[0066] Working principle

[0067] First, place one fence in the predetermined position, and then align the adjusting pipe 2 of the other fence with the adjusting pipe 2 of the first fence.

[0068] Insert the adjusting rod 11 on the aligned adjusting pipe 2, adjust the angle between the two baffle plates 1 by rotating the baffle plate 1, and the key teeth of the adjusting rod 11 match the key grooves in the adjusting pipe 2 to ensure that the adjusting rod 11 is firmly connected to the two baffle plates in the locked position.

[0069] Since the adjusting pipe 2 is composed of multiple adjusting segments, the key teeth of the adjusting rod 11 can match different adjusting segments to achieve multi-gear angle adjustment and meet different construction needs.

[0070] After the angle adjustment is completed, manually pull the horizontal support 6 away from one end of the rotating support 5 to make the horizontal support 6 and the rotating support 5 rotate around the rotating shaft 4.

[0071] The spring 13 is always in a compressed state, driving the guide rod two 12, the sliding block 7, the guide rod one 9, and the wedge block 10 to move in the direction of the guide rod two 12 pointing to the guide rod one 9.

[0072] The sliding block 7 pushes the horizontal support 6 to rotate through the connecting rod 8, making the horizontal support 6 pop out until it is perpendicular to the baffle plate 1, at which point the diagonal brace 14 provides additional support strength to ensure the stable deployment of the horizontal support 6.

[0073] After the horizontal support 6 is deployed, the sliding block 7 and the connecting rod 8 are fixed through a self-locking mechanism to prevent the horizontal support 6 from accidentally rotating after deployment.

[0074] During the movement of the wedge block 10 in the direction away from the guide rod two 12, the wedge block 10 pushes the adjusting rod 11 to move upwards, and the key teeth of the adjusting rod 11 lock the adjusting pipe 2 to ensure the stable connection between the two adjacent baffle plates 1.

[0075] When the enclosure needs to be removed, manually press the top end of the adjusting rod 11, and the bottom end of the adjusting rod 11 pushes the wedge block 10 to move in the direction close to the guide rod two 12, releasing the lock between the adjusting rod 11 and the adjusting pipe 2.

[0076] The guide rod one 9 pushes the sliding block 7, and the sliding block 7 drives the connecting rod 8 and the horizontal support 6 to move, releasing the self-locking state.

[0077] Manually rotate the horizontal support 6 to make it close to the baffle plate 1, and the diagonal brace 14 helps the horizontal support 6 to fit onto the baffle plate 1, and the spring 13 is compressed to ensure that the horizontal support 6 is firmly attached to the outer end of the baffle plate 1, completing the folding and storage of the enclosure.

[0078] The spring 13 penetrates the reinforcing strip 3 and is in contact with the reinforcing strip to ensure that the spring 13 is always in a compressed state, providing continuous elastic support to improve the deployment efficiency and stability of the horizontal support 6.

[0079] The diagonal brace 14 enhances the supporting force of the lateral support 6 after unfolding, ensures the stability and safety of the enclosure in complex construction environment, and prevents structural loosening or deformation caused by external force.

[0080] Through the high static friction coefficient between the sliding block 7 and the baffle 1, and the optimized angle between the connecting rod 8 and the guide rod 9, the lateral support 6 can be firmly locked after unfolding, and is not easy to rotate due to vibration or external force, thereby improving the safety performance of the enclosure.

[0081] The position design of the lateral support 6 after folding and adhering to the outer end of the baffle 1 makes the enclosure more compact when not in use, facilitating storage and transportation.

[0082] The adjusting pipe 2 is composed of multiple adjusting segments, and the intermittent key teeth of the adjusting rod 11 allow each key tooth to cooperate with multiple adjusting segments, thereby realizing more angle locking options, meeting the flexible adjustment requirements in different construction scenes, and improving the adaptability and practicality of the enclosure.

[0083] The optimized self-locking and locking mechanism makes the installation, adjustment and disassembly process of the enclosure more convenient and fast, reduces the operation steps of the construction personnel, and improves the work efficiency.

[0084] The combination of the reinforcing strip 3 and the diagonal brace 14, and the reasonable layout of the spring 13 make the overall structure more compact and firm, prolong the service life of the enclosure, and reduce the maintenance cost.

[0085] Through the above structure optimization and function enhancement, the embodiment 2 provides a more stable, flexible and convenient airport runway engineering construction enclosure solution, significantly improves the safety and work efficiency of the construction site, and meets the complex and variable construction requirements.

[0086] The above is only the preferred embodiment of the present application, and it should be understood that the present application is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein, by the above teachings or related technical or knowledge, and the modification and change made by the person skilled in the art without departing from the spirit and scope of the present application, should be within the protection scope of the claims attached to the present application.
