Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to an edge protection device for the rapid assembly and disassembly of a station main body. Background Technology

[0002] During the construction of the station's main structure, the installation of edge protection devices is a crucial measure to ensure the safety of construction workers. With the development of construction technology, the engineering field has placed further demands on the rapid assembly and disassembly of edge protection devices and their stability.

[0003] In existing technologies, edge protection devices typically require installation in conjunction with support columns installed at the main structure of the station. However, due to the complexity and variability of the construction site environment, the spacing between support columns often falls short of the desired precision. This necessitates cumbersome adjustments and adaptations, and sometimes additional processing, to fit the spacing of the support columns when installing the edge protection device. This not only increases installation difficulty and cost but also reduces construction efficiency. Therefore, developing an edge protection device that can adapt to different spacing distances and can be quickly installed without complex adjustments is of great significance for improving construction efficiency, reducing construction costs, and ensuring the safety of construction personnel. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to propose a quick-assembly and disassembly edge protection device for the main body of the station, so as to solve the problem that the edge protection device has low adaptability to the installation interval in the existing technology, and reduce the amount of work required for construction personnel to adjust and adapt the edge protection device.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a quick-assembly and disassembly edge protection device for a station main body, comprising a support column and a pair of vertical protective rods, a protective net fixedly connected between the pair of protective rods, the protective net being made of flexible material, and telescopic rods fixedly connected to both the upper and lower ends of the pair of protective rods, the telescopic rod comprising a main rod with a groove in the middle and an adjustment rod slidably connected in the main rod, a connecting plate fixedly provided at the bottom of one of the protective rods, a protruding post fixedly provided on the upper surface of the connecting plate, the protruding post being located on the same horizontal line as the protective rod, a groove matching the protruding post being opened at the bottom of the other protective rod, a positioning insertion rod being fixedly provided on the lower surface of the connecting plate, and an insertion hole for inserting the positioning insertion rod being opened on the support column.

[0006] By adopting the above technical solution, if the installation interval of the support columns does not match the spacing of the protective device during installation, the adjusting rod can be pulled out from the main rod, and then the positioning rod can be inserted into the socket on the support column. In certain specific situations, especially when the interval between support columns changes due to changes in ambient temperature or seasons, the protective device can dynamically adapt accordingly. This solution ensures that the distance between the support columns has a suitable tolerance range for installation, improving the error tolerance and practicality of the installation.

[0007] Furthermore, a limiting protrusion is fixedly installed at one end of the main rod cavity near the adjusting rod, and a limiting plate is fixedly installed at one end of the adjusting rod inserted into the main rod.

[0008] By adopting the above technical solution, it is considered that the extension length of the adjusting rod from the main rod should not be too long, otherwise the adjusting rod may easily detach from the main rod, reducing the overall stability of the protective device. If the extension length of the telescopic rod is forcibly matched with the distance between the support columns, the protective net will fail due to excessive stretching and tension over a long period of time. Therefore, a limiting structure is set to ensure that the extension length of the adjusting rod is limited.

[0009] Furthermore, a spring is installed between the limiting plate and the bottom end of the main rod's inner cavity.

[0010] By adopting the above technical solution, considering that the rigid connection between the support columns of the protective device is not conducive to the protective device adapting to the impact of vibration during construction, a spring is installed to improve the impact and vibration resistance of the protective device.

[0011] Furthermore, each of the two main rods is rotatably provided with a U-shaped unlocking buckle on its side wall.

[0012] By adopting the above technical solution, when the protective device needs to be stored, the adjustment rod is retracted towards the main rod, and then the unlocking buckle is rotated so that the unlocking buckle is engaged with one side of the protective rod, at which point the protective device is in the stored state; when the protective device needs to be extended for operation, the unlocking buckle is rotated so that the unlocking buckle is disengaged from the engaged state, and at the same time, the adjustment rod can be quickly ejected from the main rod with the help of the spring, which improves the ease of installation.

[0013] Furthermore, a reinforcing rod is fixedly provided between the pair of telescopic rods, and the reinforcing rod is arranged in the vertical direction.

[0014] By adopting the above technical solution, considering that the telescopic pole lacks support in the middle after it extends, which may lead to bending deformation in severe cases, a reinforcing rod is installed to reduce the probability of deformation and failure of the telescopic pole.

[0015] Furthermore, one of the protective rods is also fixedly provided with a plug-in block, which is located on the side away from the telescopic rod and has a connecting groove. The other protective rod is fixedly provided with a connecting rod that matches the connecting groove.

[0016] By adopting the above technical solution, since the lower end of the guard rod is fixed by a positioning rod, while the upper end lacks a connection and fixation, a connecting rod is provided to connect with the connecting groove, which can effectively prevent the guard rod from tipping over under the action of external forces such as crosswinds.

[0017] Furthermore, a locking groove is provided on the inner wall of the insertion hole. The locking groove includes a vertical sliding groove, which extends into an annular locking groove. A locking protrusion matching the annular locking groove is fixedly provided on the positioning rod.

[0018] By adopting the above technical solution, under strong convective weather conditions, especially during typhoons or tornadoes, according to Bernoulli's principle in fluid mechanics, strong convective winds will provide lift to the protective device. When the lift reaches a certain level, the protective rod will detach from the support column, potentially causing damage and failure of the device. The annular locking groove and locking protrusion effectively lock the protective device in the vertical direction.

[0019] Furthermore, the positioning rod has a chamfer, and the upper end of the support column has an inverted umbrella-shaped slope.

[0020] By adopting the above technical solution, the chamfer on the positioning rod and the inverted umbrella-shaped slope on the upper end of the support column serve as a guide for the insertion of the positioning rod, while also providing room for error during positioning, making the insertion process smoother and improving installation efficiency.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This edge protection device, with its telescopic rod design, can flexibly adapt to support columns with different spacing, improving the fault tolerance and practicality of installation. Meanwhile, the limiting structure and spring design ensure the stability and impact resistance of the device, enhancing its ability to adapt to complex construction environments.

[0023] 2. The design of the unlocking buckle and reinforcing rod further enhances the convenience and stability of the protective device. The unlocking buckle facilitates quick storage and deployment, while the reinforcing rod effectively prevents the telescopic rod from bending and deforming after extension, ensuring the overall strength and reliability of the device.

[0024] 3. The innovative design of the plug-in block, connecting groove, and locking groove enhances the stability and safety of the protective device. Especially in strong winds and convective weather, the cooperation between the locking groove and the locking protrusion effectively prevents the protective rod from detaching from the support column, ensuring the reliability and durability of the device in harsh environments.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] Example, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The device includes a support column 1 and a pair of vertical protective rods 2. A protective net 3, made of flexible material, is fixedly connected between the pair of protective rods 2. Telescopic rods 4 are fixedly connected to both ends of the pair of protective rods 2. The telescopic rods 4 include a main rod 41 with a groove in the middle and an adjustment rod 42 slidably connected in the main rod 41. A connecting plate 21 is fixedly installed at the bottom of one of the protective rods 2, and a protruding post 22 is fixedly installed on the upper surface of the connecting plate 21. The protruding post 22 is located on the same horizontal line as the protective rod 2. A groove 23 matching the protruding post 22 is opened at the bottom of the other protective rod 2. A positioning insertion rod 24 is fixedly installed on the lower surface of the connecting plate 21. An insertion hole 11 for inserting the positioning insertion rod 24 is opened on the support column 1. During the installation of the protective device, if the installation interval of the support column 1 does not match the spacing of the protective device, the adjustment rod 42 can be pulled out from the main rod 41, and then the positioning insertion rod 24 can be inserted into the insertion hole 11 on the support column 1. In certain specific situations, particularly when changes in ambient temperature or seasonal variations cause corresponding changes in the spacing of support columns 1, the protective device can dynamically and synchronously adapt accordingly. This approach ensures that the distance between support columns 1 has a suitable installation tolerance range, improving the installation's error tolerance and practicality.

[0032] In this embodiment, a limiting protrusion 5 is fixedly installed at one end of the main rod 41 near the adjusting rod 42, and a limiting plate 51 is fixedly installed at the other end of the adjusting rod 42 that is inserted into the main rod 41. Considering that the extension length of the adjusting rod 42 from the main rod 41 should not be too long, otherwise the adjusting rod 42 may easily detach from the main rod 41, reducing the overall stability of the protective device. If the extension length of the telescopic rod 4 is forcibly matched with the distance between the support column 1, the protective net 3 will fail due to excessive stretching over a long period. Therefore, a limiting structure is provided to ensure that the extension length of the adjusting rod 42 is limited.

[0033] In this embodiment, a spring 52 is installed between the limiting plate 51 and the bottom end of the inner cavity of the main rod 41. Considering that the rigid connection between the protective device and the support column 1 is not conducive to the protective device adapting to the impact of vibration during construction, the spring 52 is provided to improve the impact and vibration resistance of the protective device.

[0034] In this embodiment, a U-shaped unlocking buckle 6 is rotatably provided on the side wall of each pair of main rods 41. When the protective device needs to be stored, the adjusting rod 42 is retracted towards the main rod 41, and then the unlocking buckle 6 is rotated so that the unlocking buckle 6 is engaged with one of the protective rods 2, at which point the protective device is in the stored state; when the protective device needs to be extended for operation, the unlocking buckle 6 is rotated so that the unlocking buckle 6 is disengaged from the engaged state, and at the same time, the adjusting rod 42 can be quickly ejected from the main rod 41 with the help of the spring 52, which improves the ease of installation.

[0035] In this embodiment, a reinforcing rod 7 is fixedly installed between a pair of telescopic rods 4, and the reinforcing rod 7 is arranged in the vertical direction. Considering that the telescopic rod 4 lacks support in the middle after it is extended, which may cause the telescopic rod 4 to bend and deform in severe cases, the reinforcing rod 7 is provided to reduce the probability of the telescopic rod 4 deforming and failing.

[0036] In this embodiment, one of the protective rods 2 is also fixedly equipped with a plug-in block 8, which is located on the side away from the telescopic rod 4. The plug-in block 8 has a connecting groove 81. The other protective rod 2 is fixedly equipped with a connecting plug 82 that matches the connecting groove 81. Since the lower end of the protective rod 2 is fixed by a positioning plug 24, but its upper end lacks a connecting fixation, the connecting plug 82 is provided to connect with the connecting groove 81, which can effectively prevent the protective rod 2 from tipping over under the action of external forces such as crosswinds.

[0037] In this embodiment, a locking groove 9 is provided on the inner wall of the insertion hole 11. The locking groove 9 includes a vertical sliding groove 91, which extends into an annular locking groove 92. A locking protrusion 93 matching the annular locking groove 92 is fixedly provided on the positioning rod 24. In strong convective weather, especially during typhoons or tornadoes, according to Bernoulli's principle in fluid mechanics, strong convective winds will provide lift to the protective device. When the lift reaches a certain level, the protective rod 2 will detach from the support column 1, potentially causing damage and failure of the device. The annular locking groove 92 and the locking protrusion 93 effectively lock the protective device in the vertical direction.

[0038] In this embodiment, the positioning rod 24 has a chamfer 25, and the upper end of the support column 1 has an inverted umbrella-shaped slope 12. The chamfer 25 on the positioning rod 24 and the inverted umbrella-shaped slope 12 on the upper end of the support column 1 serve to guide the insertion of the positioning rod 24, while also providing room for error during positioning, making the insertion process smoother and improving installation efficiency.

[0039] Specific implementation process:

[0040] During the installation of edge protection devices on the main body of the station, the support column 1 is first fixedly buried in the ground. The spacing of the support column 1 can be adjusted within a certain tolerance range. Then, the locking protrusion 93 is aligned with the vertical sliding groove 91 on the support rod and inserted into the annular locking groove 92. After being inserted into the annular locking groove 92, the positioning rod 24 is rotated to lock the positioning rod 24 in the vertical direction. After the positioning rod 24 is locked, the unlocking buckle 6 is rotated, and the adjusting rod 42 sleeved in the main rod 41 is quickly ejected under the action of the spring 52, inserting the insertion hole 11 into the groove 23 of the adjacent guard rod 2. Finally, the connecting rod 82 at the upper end of the guard rod 2 is inserted into the insertion block 8 of the adjacent guard rod 2 to ensure that the guard rod 2 is not easy to tip over under the action of external force.

[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
