Description

Technical Field

[0001] This utility model relates to the field of guardrail equipment technology, and in particular to a temporary guardrail for high-altitude operations on steel beam segments. Background Technology

[0002] During the installation of steel beams, edge protection facilities must be installed simultaneously to ensure safety throughout the construction process. The main function of edge guardrails is to prevent construction workers from falling due to accidentally approaching the edge while working at heights.

[0003] Existing technology, such as a utility model of an edge protection fence (authorization number CN221742282U), involves multiple fences connected by hinges, allowing them to be folded when not in use, reducing the overall size and facilitating movement and transportation. This utility model has a simple structure, is easy to operate, and is worth promoting. Currently, there is a lack of edge guardrails that facilitate the transfer, deployment, and retraction of steel beams, providing protection for installation-related work such as installation and welding.

[0004] Therefore, in order to address the above problems, a temporary edge guardrail for high-altitude operations on steel beam segments is proposed to solve these problems. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by developing a temporary edge guardrail for high-altitude operations on steel beam segments. This invention can be quickly extended and retracted according to the width of the steel beam or other construction requirements, enabling the guardrail to adapt to steel beam segments of different widths and ensuring effective protection in various construction scenarios.

[0006] The technical solution to the technical problem solved by this utility model is as follows: This utility model provides a temporary edge guardrail for high-altitude operations on steel beam segments, comprising: a set of column assemblies, including a set of columns, which are the main supporting structure of the entire guardrail, used to fix the position of the guardrail and provide stability; each of the columns is provided with a cross groove for accommodating and guiding a fixed block and a movable block, ensuring that the movable block can move along a predetermined path; a set of extension assemblies, including a set of round rods, the upper end of each round rod is connected to an upper U-axis, the lower end of each round rod passes through a lower U-axis, and each upper U-axis rotates... The upper end of the symmetrical first connecting rod is connected to the upper end of each of the lower U-axis, which is rotatably connected to the lower end of the symmetrical second connecting rod. The centers of adjacent first and second connecting rods are coaxially and rotatably connected. The lower end of each first connecting rod is rotatably connected to a moving block, and the upper end of each second connecting rod is rotatably connected to a fixed block. Each fixed block and each moving block are respectively disposed in a corresponding cross groove. Each fixed block is connected to a corresponding column. The combination of the round rod, upper U-axis, lower U-axis, first connecting rod, and second connecting rod achieves the telescopic function of the guardrail. The round rod is connected to the connecting rod via the upper and lower U-axis, and adjacent first and second connecting rods are rotatably connected via a central cross groove, forming a telescopic structure. The moving block and fixed block are respectively connected to both ends of the connecting rod and disposed in the cross groove of the column. The telescopic adjustment of the guardrail is achieved through the relative movement of the moving block and the fixed block.

[0007] As an optimization, an adjustment component is also included. This component comprises a mounting base, a central column connected to the mounting base, a bearing-connected screw to the mounting base, and two central upper U-shafts respectively connected to movable seats. The two reverse threads of the screw are respectively threaded to the corresponding movable seats. The movable seats are connected to the two central upper U-shafts. By rotating the screw, the movable seats move along the screw, thereby driving the upper U-shafts and the round rod to move, achieving the telescopic adjustment of the guardrail.

[0008] As an optimization, at least one end of the screw is connected to an anti-detachment block to prevent the moving seat from accidentally falling off during the adjustment process, thereby ensuring the stability and reliability of the adjustment assembly.

[0009] As an optimization, at least the two ends of the column are respectively connected to the mounting base plate, and each of the four corners of the mounting base plate is provided with through holes for firmly installing the guardrail on the working surface of the steel beam by bolts or other fasteners, so as to ensure the stability of the guardrail.

[0010] As an optimization, a walking assembly is also included, which comprises two wheel plates, with bolts connected to the four corners of each wheel plate. A set of bolts matches a set of through holes. Each wheel plate is rotatably connected to a wheel seat, and each wheel seat is connected to a wheel by a bearing. Bolts pass through the through holes and are threaded to connect to nuts, thereby enabling the installation of the walking assembly and giving the guardrail a mobile function. This facilitates rapid movement and positioning on steel beams or other working surfaces, improving construction efficiency.

[0011] As an optimization, the first link and the second link are of the same model and can be used interchangeably. This design simplifies the manufacturing process, reduces production costs, and also facilitates maintenance and replacement of parts.

[0012] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects: (1) This utility model allows the extension and retraction adjustment of the guardrail to be completed by a simple rotation operation through the adjustment component. The reverse thread design of the screw can quickly drive the moving seat to move along the screw, thereby realizing the rapid extension and retraction of the guardrail and greatly improving the construction efficiency.

[0013] (2) The posts in the post assembly of this utility model are the main supporting structures of the guardrail. Through the cooperation of the cross groove with the fixed block and the moving block, the stability of the guardrail is ensured during the extension and retraction process. The cross groove can guide the moving block to move along a predetermined path to prevent it from deviating or getting stuck during the extension and retraction process.

[0014] (3) The movable function of the guardrail of this utility model, combined with its telescopic adjustment capability, can quickly adapt to different construction environments. Construction personnel can quickly adjust the position and length of the guardrail according to actual needs, improve construction efficiency, and reduce the time wasted due to equipment adjustments.

[0022] like Figures 1 to 4As shown in Embodiment 1: A steel beam segment high-altitude operation edge guardrail includes: a set of column assemblies 1, including a set of columns 11, the columns 11 being the main support structure of the entire guardrail, used to fix the position of the guardrail and provide stability; each column 11 is provided with a cross groove 12 for accommodating and guiding a fixed block 24 and a movable block 25, ensuring that the movable block 25 can move along a predetermined path; a set of extension assemblies 2, including a set of round rods 22, the upper end of each round rod 22 being connected to an upper U-shaft 21, the lower end of each round rod 22 passing through a lower U-shaft 26, and each upper U-shaft 21 being rotatably connected to the upper end of a symmetrical first connecting rod 23. Each lower U-axis 26 is rotatably connected to the lower end of a symmetrical second connecting rod 27. Adjacent first connecting rods 23 and second connecting rods 27 are coaxially and rotatably connected at their centers. The lower end of each first connecting rod 23 is rotatably connected to a moving block 25, and the upper end of each second connecting rod 27 is rotatably connected to a fixed block 24. Each fixed block 24 and each moving block 25 are respectively disposed within a corresponding cross groove 12. Each fixed block 24 is connected to a corresponding column 11. The combination of the round rod 22, upper U-axis 21, lower U-axis 26, first connecting rod 23, and second connecting rod 27 enables the retractable function of the guardrail. The round rod 22 connects to the connecting rod via the upper U-axis 21 and lower U-axis 26. Adjacent first and second connecting rods are rotatably connected at their centers, forming a retractable structure. The moving block 25 and fixed block 24 are respectively connected to both ends of the connecting rod and disposed within the cross groove 12 of the column. The relative movement of the moving block and the fixed block enables the retraction and adjustment of the guardrail.

[0023] It also includes an adjustment component 3, which includes a mounting base 34. A central column 11 is connected to the mounting base 34, and the mounting base 34 is connected to a bearing screw 32. Two central upper U-shafts 21 are respectively connected to movable seats 33. The two reverse threads of the screw 32 are respectively threaded to the corresponding movable seats 33. The movable seats 33 are connected to the two central upper U-shafts 21. By rotating the screw 32, the movable seats 33 move along the screw, thereby driving the upper U-shafts 21 and the round rod 22 to move, thus realizing the telescopic adjustment of the guardrail.

[0024] The screw 32 has a self-locking function.

[0025] At least one end of the screw 32 is connected to an anti-detachment block 31 to prevent the moving seat 33 from accidentally falling off during the adjustment process, thus ensuring the stability and reliability of the adjustment assembly 3.

[0026] At least two of the columns 11 are connected to mounting base plates 13 respectively. Each mounting base plate 13 has a through hole 14 at each of its four corners for securing the guardrail to the working surface of the steel beam with bolts or other fasteners to ensure the stability of the guardrail.

[0027] The first link 23 and the second link 27 are of the same model and can be used interchangeably. This design simplifies the manufacturing process, reduces production costs, and also facilitates maintenance and replacement of parts.

[0028] The workflow of this embodiment is as follows: Let's take unfolding as an example: Rotating screw 32 causes movable seat 33 to move, which in turn moves the two upper U-shafts 21, the round rod 22, and the lower U-shaft 26. Under the limiting action of the first connecting rod 23 and the second connecting rod 27, the lower U-shaft 26 moves along the round rod 22. The lower U-shaft 26 then causes the second connecting rod 27 to swing, which in turn causes the first connecting rod 23 to swing. The first connecting rod 23 then causes movable block 25 to move along the column 11 within the cross groove 12. Two of the three movable blocks 25 (excluding the middle one) move the two columns 11, which in turn move the adjacent extension components 2. This results in the movement of all extension components 2 and the remaining columns 11. The columns 11 then move the mounting base plate 13, thus unfolding the guardrail. Bolts are then used to pass through the through holes 14 to connect the bridge, thus installing the guardrail.

[0029] Example 2: This example further elaborates on Example 1 and includes a walking component 4. The walking component 4 includes two wheel plates 42, with bolts 41 connected to the four corners of each wheel plate 42. A set of bolts 41 matches a set of through holes 14. Each wheel plate 42 is rotatably connected to a wheel seat 43, and each wheel seat 43 is bearing a wheel 44. The bolts 41 pass through the through holes 14 and are threaded to a nut, thus enabling the installation of the walking component 4. This allows the guardrail to move quickly on steel beams or other working surfaces, improving construction efficiency.

[0030] The workflow of this embodiment is as follows: Insert bolts 41 through holes 14 and thread them onto nuts. Move the device along the bridge deck to the preset position, then unfold it. After unfolding, unscrew the nuts, remove the walking assembly 4, and secure it.

[0031] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
