Description

Technical Field

[0001] This utility model relates to the field of guardrails, and in particular to a reusable alloy steel guardrail. Background Technology

[0002] Alloy steel guardrails are structures used to provide safety protection, commonly found in various locations such as construction sites, traffic intersections, and industrial areas. Alloy steel is an alloy with high strength, hardness, and corrosion resistance, making it widely used in the manufacture of robust guardrails capable of withstanding external impacts. Reusability is a crucial consideration in the design and manufacture of guardrails, meaning that they can maintain their performance and functionality through repeated use. Guardrails are typically designed for easy disassembly and reassembly.

[0003] A search revealed that patent CN221645650U discloses a reusable alloy steel guardrail, which includes a pair of bases. The bases on both sides have internal cavities, and a pair of springs are fixedly connected to both sides of the internal cavities. The other end of each spring is fixedly connected to a connecting ball. A pair of support columns are provided on the top of the bases on both sides, and the support columns are slidably connected to the inside of the bases. Limiting holes are provided on both sides of the support columns, and the limiting holes correspond to the connecting balls.

[0004] The existing equipment uses several pins to pass through through holes to install the fixing plate on the support column, so as to symmetrically support the alloy steel guardrail from both ends. However, when encountering a large span connection, the middle bearing capacity of the alloy steel guardrail is insufficient. Once it is slightly shaken, it will amplify into a large-scale shaking and tilting behavior.

[0005] Therefore, it is necessary to provide a reusable alloy steel guardrail to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a reusable alloy steel guardrail.

[0007] This utility model provides a reusable alloy steel guardrail, including a clamping and mounting structure, a fixed protective structure inside the clamping and mounting structure, a movable protective structure at the front end of the fixed protective structure, and a movable structure at the bottom end of the clamping and mounting structure.

[0008] The clamping and mounting structure includes two brackets, each of which has a connecting plate 1 at both ends. Each of the four connecting plates 1 has a connecting plate 2 installed on its top via a through connecting bolt. The top of the two connecting plates 2 on the same side of the four connecting plates 2 is provided with a clamping frame.

[0009] In order to achieve the effect of protection and obstruction, this utility model provides a reusable alloy steel guardrail. Preferably, the fixed protective structure includes a fixed protective frame clamped between two brackets and two clamping frames, and the interior of the fixed protective frame is evenly provided with several vertical plates.

[0010] To facilitate easy disassembly and relocation, this utility model provides a reusable alloy steel guardrail, preferably with two handles symmetrically arranged at both ends of the back of the fixed guardrail.

[0011] In order to expand the protection area, this utility model provides a reusable alloy steel guardrail. Preferably, the movable protection structure includes four sliding grooves symmetrically opened on both sides of the front of the fixed protection frame. A slider is slidably arranged inside each of the four sliding grooves. The front of the two sliders on the same side of the four sliders is provided with a movable protection frame.

[0012] To increase the blocking effect, this utility model provides a reusable alloy steel guardrail. Preferably, the interiors of the two movable guardrails are each provided with several vertical bars at equal intervals.

[0013] To achieve flexible mobility, this utility model provides a reusable alloy steel guardrail. Preferably, the movable structure includes roller brackets disposed at the bottom ends of the two brackets, and movable rollers are provided on both sides of the bottom ends of the two roller brackets.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This reusable alloy steel guardrail features a movable clamping and mounting structure that provides support at any position. It solves the problem of existing equipment that uses pins through holes to install fixing plates on support columns to symmetrically support the alloy steel guardrail from both ends. However, when encountering large-span connections, the central support of the alloy steel guardrail is insufficient, and even a slight sway can amplify into a large-scale swaying and tipping.

[0016] This reusable alloy steel guardrail features a movable protective structure. Two movable protective frames slide along a groove at their rear ends, moving the two frames away from or towards each other. This solves the problem of existing equipment that uses docking to increase the protective area, requiring the removal of all pins before adding more alloy steel guardrails, which is inconvenient for installation.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of a preferred embodiment of a reusable alloy steel guardrail provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the back side; Figure 3 for Figure 1 The diagram shows the structural schematic of the clamping and mounting structure. Figure 4 for Figure 1 A schematic diagram of the movable protective structure shown. Figure 5 for Figure 1 The schematic diagram of structure A shown includes a reusable alloy steel guardrail, including a clamping and mounting structure 1, a fixed protective structure 2 inside the clamping and mounting structure 1, a movable protective structure 3 at the front end of the fixed protective structure 2, and a movable structure 4 at the bottom end of the clamping and mounting structure 1.

[0025] The clamping and mounting structure 1 includes two brackets 101. Each of the top ends of the two brackets 101 is provided with a connecting plate 102. The top of each of the four connecting plates 102 is provided with a connecting plate 104 through a connecting bolt 103. The top of the two connecting plates 104 on the same side of the four connecting plates 104 is provided with a clamping frame 105.

[0026] It should be noted that: by using two connecting bolts 103 to penetrate the interior of the two connecting plates 102 and the two connecting plates 104, the corresponding brackets 101 and clamping frames 105 are connected and fixed, so as to symmetrically clamp and fix the fixed protective frame 201. The fixed protective frame 201 is made of alloy steel.

[0027] In the specific implementation process, refer to Figure 1 and Figure 2 As shown, the fixed protective structure 2 includes a fixed protective frame 201 clamped between two brackets 101 and two clamping frames 105. Several vertical plates 202 are evenly arranged inside the fixed protective frame 201, and two handles 203 are symmetrically arranged at both ends of the back of the fixed protective frame 201.

[0028] It should be noted that: the two sets of brackets 101 and clamping frame 105 are connected and fixed together to clamp and fix the protective frame 201. The fixed protective frame 201 relies on several vertical plates 202 inside to implement the blocking behavior, reduce the weight of the equipment itself, and improve the efficiency of installation and disassembly. Both sets of brackets 101 and clamping frame 105 are made of alloy steel.

[0029] In the specific implementation process, refer to Figure 4 and Figure 5 As shown, the movable protective structure 3 includes four sliding grooves 301 symmetrically opened on both sides of the front of the fixed protective frame 201. A slider 302 is slidably arranged inside each of the four sliding grooves 301. A movable protective frame 303 is provided on the front of the two sliders 302 on the same side of the four sliders 302. Several vertical rods 304 are equidistantly arranged inside the two movable protective frames 303.

[0030] It should be noted that: sliding the two movable protective frames 303 enables the two sliders 302 on their back sides to slide along the corresponding grooves 301 on the front of the fixed protective frame 201, promoting the two movable protective frames 303 to move away from or towards each other, thus forming a blocking action together with the fixed protective frame 201. Both movable protective frames 303 are made of alloy steel.

[0031] In the specific implementation process, refer to Figure 2 and Figure 3As shown, the movable structure 4 includes roller brackets 401 disposed at the bottom of the two brackets 101, and movable rollers 402 are disposed on both sides of the bottom of the two roller brackets 401.

[0032] It should be noted that roller brackets 401 are installed at the bottom of the two brackets 101 to facilitate the subsequent installation of movable rollers 402. On the one hand, this provides four-corner support to prevent the equipment from tipping over, and on the other hand, it facilitates the use of the four movable rollers 402 to control the movement of the equipment. Both roller brackets 401 are made of alloy steel.

[0033] The working principle of the reusable alloy steel guardrail provided by this utility model is as follows:

[0034] In use, the fixed protective frame 201 is lifted using two handles 203 and placed on top of two brackets 101. Clamping frames 105 are installed on the top of each bracket 101. Two connecting bolts 103 are then inserted through the interiors of two connecting plates 102 and 104 to connect the corresponding brackets 101 and clamping frames 105, thus fixing the fixed protective frame 201 in place. The two movable protective frames 303 are slid, allowing the two sliders 302 to slide along the grooves 301, moving the two movable protective frames 303 away from or towards each other. This, together with the fixed protective frame 201, forms a barrier, increasing the barrier range. Roller brackets 401 are installed at the bottom of the two brackets 101 to facilitate the subsequent installation of movable rollers 402, enabling the four movable rollers 402 to control the equipment's displacement.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
