DETAILED DESCRIPTION

[0028] The utility model is further described below in combination with the drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the utility model and does not constitute a limitation on the utility model. The specific structure and functional details disclosed in this paper are only used to describe the example embodiments of the utility model. However, the utility model can be embodied in many alternative forms, and should not be understood as being limited in the embodiments described in this paper.

[0029] As Figure 1 shown, Figure 1 The structure schematic drawing after the installation of the protective device is provided for the embodiment of the application, a protective device, the protective device includes guardrail main body 100, stand 201, first reinforcing piece 301 and second reinforcing piece 302, wherein:

[0030] As Figure 1 shown, the guardrail main body 100 is regarded as a relative whole and forms a protection effect in the operation area.

[0031] The stand 201 is arranged in multiple, and the stand 201 is fixedly connected at both ends of the guardrail main body 100, the stand 201 is internally provided with a connecting cavity, it should be noted that according to the length arrangement of the protection area, one guardrail main body 100 can be used as a basic unit, and the guardrail main body 100 is fixedly connected on both sides of the guardrail main body 100 through the stand 201, and the number of guardrail main body 100 is increased to achieve the target requirement of the protection area arrangement, and the arrangement applicability is strong.

[0032] As Figure 1 shown, the first reinforcing piece 301 has a first section extending into the connecting cavity and fixedly connected with the stand 201, and a second section extending and fixed at the lower part of the mounting surface, so that the stand 201 is fixedly installed on the mounting surface, the second section of the first reinforcing piece 301 extends to the lower part of the mounting surface, the length extension of the second section improves the stability of the first reinforcing piece 301 as a whole, and provides a more reliable installation basis for the stand 201.

[0033] As Figure 1 , Figure 3 shown, wherein Figure 3 The second reinforcing piece 302 is fixedly arranged in the stand 201, the two ends of the second reinforcing piece 302 respectively penetrate the stand 201 and are fixedly connected with the guardrail main body 100, the second reinforcing piece 302 is fixedly connected in the stand 201, avoiding that the guardrail main body 100 is directly connected with the stand 201, through a more reliable installation basis and connection relationship, the protection capability between the stand 201 and the guardrail assembly is improved.

[0034] In an optional embodiment, the working principle of the protective device in this application is as follows: The protective device includes a guardrail body 100, a post 201, a first reinforcing member 301, and a second reinforcing member 302. The post 201 is fixedly connected to both ends of the guardrail body 100. A connecting cavity is provided inside the post 201. The first reinforcing member 301 has a first section extending into the connecting cavity and fixedly connected to the post 201, and a second section extending and fixedly fixed to the lower part of the mounting surface, so that the post 201 is fixedly mounted on the mounting surface. The second reinforcing member 302 is fixedly disposed inside the post 201. Both ends of the second reinforcing member 302 pass through the post 201 and are fixedly connected to the guardrail body 100, forming a connection between the post 201 and the guardrail body 100. On the road surface, the first reinforcing member 301 extends below the mounting surface to form a more stable connection with the post 201, ensuring that the protective device, based on the mounting surface, can stably provide protection within the installation area. The first reinforcing member 301 provides a more stable blocking capability. When the guardrail body 100 is subjected to impact force, the guardrail body 100 and the post 201 undergo relative torsion to varying degrees in different directions. Stress concentration at the connection between the guardrail body 100 and the post 201 can directly lead to fracture and separation, causing the entire protective device to fail. The second reinforcing member 302 further maintains the connection strength between the guardrail body 100 and the post 201, improving the connection reliability during impact force application and providing stable protection within the relevant area.

[0035] like Figure 1 , Figure 2 As shown, where Figure 2 A partial sectional view of the support member 102 is provided for an embodiment of this application. In an optional embodiment, the guardrail body 100 includes two horizontal beams 101 arranged at intervals and in parallel. A plurality of support members 102 are arranged at intervals between the horizontal beams 101, and the two ends of the support members 102 are fixedly connected to the horizontal beams 101.

[0036] like Figure 1 , Figure 2 As shown, the two crossbeams 101 arranged at intervals provide lateral connection and support at different positions, and further maintain impact protection in the longitudinal range through the two crossbeams 101. The multiple support members 102 arranged at intervals between the two crossbeams 101 maintain the relative stability between the two crossbeams 101 and ensure that the crossbeams 101 are uniformly and reliably arranged at the target position. On the other hand, the multiple support members 102, based on the crossbeams 101, also provide uniform protection between the two parallel crossbeams 101, improving protection density and stability.

[0037] like Figure 1 ,Figure 2 As shown, in an optional embodiment, two of the cross beam members 101 are each provided with an assembly hole 303, one end of the support member 102 extends into the assembly hole 303 on one of the cross beam members 101, and the other end extends into the assembly hole 303 on the other cross beam member 101, and is fixedly connected to the cross beam members 101 by a fixing screw 304.

[0038] Specifically, the two cross beam members 101 serve as the main load-bearing and support components. Each cross beam member 101 is provided with a specific assembly hole 303 to ensure that the support member 102 can be properly installed and function.

[0039] The support member 102 is a key component that connects the two cross beam members 101. One end of the support member 102 has an end that can be inserted into the assembly hole 303 on the cross beam member 101, and the other end can also be inserted into the assembly hole 303 on the other cross beam member 101. This design allows the support member 102 to span the two cross beam members 101, providing the necessary connection and support, and each support member 102 is connected between the corresponding two assembly holes 303 on the two cross beam members 101.

[0040] The assembly hole 303 not only provides space for the installation of the support member 102, but also ensures that the support member 102 can be properly aligned and fixed on the cross beam member 101. The arrangement of the assembly hole 303 takes into account the strength of the cross beam member 101 and the stability of the support member 102 to ensure the reliability of the entire structure.

[0041] To ensure that the connection between the support member 102 and the cross beam member 101 is both firm and stable, a fixing screw 304 is used for fastening. The fixing screw 304 is fixed through one end of the support member 102 to tightly connect the cross beam member 101 and one end of the support member 102, and the fixing screw 304 is only connected to one end of the support member 102 to maintain the stable connection state of the end of the support member 102 where the fixing screw 304 is arranged, and the end of the support member 102 where the fixing screw 304 is not arranged can release stress to avoid secondary damage caused by the overall shedding of the support member 102.

[0042] When maintenance or replacement is needed, the support member 102 can be relatively easily disassembled and reinstalled, which greatly improves the efficiency of maintenance work.

[0043] In an optional embodiment, the middle part of the support member 102 is provided as a solid square steel, the end parts of the support member 102 are respectively provided as cylindrical heads for extending into the assembly holes 303, and the cylindrical heads are respectively welded and fixed to the cross beam members 101.

[0044] Specifically, the middle part of the support member 102 is designed as a solid square steel to provide higher stiffness and load-carrying capacity. The solid square steel is superior in bending and torsional resistance due to its solid cross-sectional characteristics, which makes the support member 102 exhibit better stability and durability when subjected to large loads or torques.

[0045] The end part of the support member 102 is designed as a cylindrical head shape, which allows the support member 102 to be easily extended into the mounting hole 303 on the beam member 101. The cylindrical head design helps to reduce stress concentration and facilitates welding and fixation. In actual application, it can ensure the close fit between the support member 102 and the beam member 101, thereby improving the reliability of the connection.

[0046] In addition, the cylindrical head end of the support member 102 is welded and fixed with the beam member 101, which provides very strong fixing force and stability. Welding is a very mature connection technology that melts and fuses metals together at high temperatures to form a solid connection point. This connection method not only can withstand large static and dynamic loads, but also has good sealing and corrosion resistance, suitable for various industrial and construction environments.

[0047] As shown in Figure 1 , Figure 2 In an optional embodiment, the guardrail body 100 further comprises two longitudinal beam members 103, the end parts of which are fixedly connected to the beam member 101 and form a rectangular frame together with the beam member 101, and the longitudinal beam members 103 are fixedly connected to the second reinforcing member 302 by bolts 305.

[0048] Specifically, the arrangement of the longitudinal beam members 103 and the beam member 101 is designed to enhance the structural stability and safety. The end parts of the two longitudinal beam members 103 are combined with the beam member 101 by fixed connection, which can be achieved by welding to ensure the firmness and durability of the connection point. The connection between the longitudinal beam members 103 and the beam member 101 is not prone to breakage or loosening due to external forces.

[0049] To form a more stable structure, the two longitudinal beam members 103 and the beam member 101 together form a rectangular frame. This rectangular frame design not only enhances the overall rigidity of the guardrail, but also improves its ability to withstand lateral impact. When subjected to external impact, the rectangular frame can evenly distribute the stress and reduce local stress concentration, thereby protecting the guardrail from deformation or damage.

[0050] In addition, each longitudinal beam 103 is also fixedly connected to the second reinforcing member 302 through a bolt 305. This connection provides additional stability and security. The bolt 305 connection is a detachable connection that allows for maintenance or replacement of components without damaging the guardrail body 100. The bolt 305 connection also provides space for adjustment to accommodate different installation environments and requirements. Through the fixed connection of the longitudinal beam 103 to the cross beam 101 and the bolt 305 connection of the longitudinal beam 103 to the second reinforcing member 302, the stability and security of the guardrail body 100 are greatly improved.

[0051] In an optional embodiment, the first reinforcing member 301 is a solid round steel to ensure that the first reinforcing member 301 provides impact resistance and improves protection.

[0052] As shown in Figure 1 , Figure 3 In an optional embodiment, the second reinforcing member 302 is provided in multiple numbers and is arranged in the vertical column 201 in a spaced manner along the height direction of the vertical column 201, uniformly distributing the connection between the vertical column 201 and the longitudinal beam 103 to improve reliability under stress.

[0053] As shown in Figure 1 , Figure 3 In an optional embodiment, the second reinforcing member 302 penetrates the vertical column 201 and is fixed to the vertical column 201 by welding. The end of the second reinforcing member 302 is provided with a stepped surface 401, and the guardrail body 100 is provided with a fitting groove 402 for abutting against the stepped surface 401.

[0054] Further, the second reinforcing member 302 penetrates the entire vertical column 201 and is fixed to the vertical column 201 by welding. This allows the second reinforcing member 302 to bear the load together with the vertical column 201, enhancing the stability of the entire guardrail. In addition, the second reinforcing member 302 serves as a basis for the connection and fixation of the longitudinal beam 103. The end of the second reinforcing member 302 is designed with a stepped surface 401, forming a convex platform that provides a stable and precise support point for the guardrail body 100. The guardrail body 100 is provided with a fitting groove 402 that abuts against the stepped surface 401 of the second reinforcing member 302, ensuring a tight fit and stable connection between the guardrail body 100 and the reinforcing member.

[0055] As shown in Figure 1As shown, in the optional embodiment, the protection device further comprises a sleeve 202 pre-set below the installation surface, and the first reinforcing member 301 is fixedly arranged in the sleeve 202. The sleeve 202 can be pre-fabricated in advance through pre-setting below the installation surface. The installation surface can be a hardened ground or other installation area in different arrangement environments. The sleeve 202 is pre-fabricated in advance, and the first reinforcing member 301 is extended into the sleeve 202, and the concrete can be added in the sleeve 202. After the concrete is completely solidified, the installation reliability of the first reinforcing member 301 is maintained, which replaces the direct placement or bolt 305 fixation on the installation surface, and the stability and protection capability are increased.
