[0003] At present, in terms of the safety protection of rail transit, the industry usually installs guardrails on both sides of the roadbed where the track is installed. When running, the train runs between the guardrails on both sides. At present, the existing guardrails on the market have a simple and fixed structure, which includes a number of columns arranged at intervals, and a number of railings are arranged between two adjacent columns, and both ends of each railing are welded to the corresponding column, that is, during installation, the column is installed first, and then the railing is welded to the column, so that the entire guardrail will eventually form an integral structure.

[0029] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 6 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0030] Figure 1 This is a structural diagram of an embodiment of a rail transit guardrail of the utility model; Figure 2 This is a schematic diagram of the installation of a rail transit guardrail of the utility model. Figure 1 and Figure 2 As shown, the rail transit guardrail provided in this embodiment is installed on both sides of the roadbed 7, and both sides of the roadbed 7 are provided with reserved installation positions 6, which facilitates the installation of the guardrail. At this time, the rail transit guardrail provided in this embodiment includes: a base 1, a column 2 and a railing 3, and the base 1, the column 2 and the railing 3 are all detachable structures to improve the structural flexibility of the guardrail.

[0031] Specifically, the base 1 is installed at the installation positions 6 reserved on both sides of the roadbed 7, and the installation positions 6 reserved on both sides of the roadbed 7 provide a stable installation carrier for the installation of the guardrail, ensuring that the guardrail after installation is more stable. In addition, a plurality of bases 1 are arranged at intervals along the length direction of the road, ensuring that the guardrail can be continuously arranged on both sides of the road in the future, realizing long-distance protection.

[0032] Specifically, the lower end of the column 2 is installed on the base 1. Preferably, the column 2 extends in the vertical direction so that the guardrail has a certain height and improves the protection capability. In addition, during installation, each base 1 corresponds to a column 2, that is, a column 2 is installed on a base 1, ensuring that the column 2 can be stably installed on the roadbed 7 through the base 1, providing conditions for the subsequent stable installation of the railing 3.

[0033] Specifically, a plurality of railings 3 are horizontally placed between two adjacent columns 2, and the intervals between the two adjacent columns 2 are filled by the railings 3, thereby forming a continuously arranged guardrail to achieve continuous protection. In addition, the railings 3 located between the same two columns 2 are arranged at intervals in the vertical direction, so that there can be intervals between the two adjacent railings 3, which is convenient for air flow, a smaller wind-receiving area, higher safety and stability, and in addition, it can also reduce the use of materials and reduce costs while meeting the protection requirements. In addition, the two ends of each railing 3 are respectively installed on the corresponding two columns 2, so that the railing 3 can be stably supported by the two columns 2, meeting the installation requirements of the railing 3.

[0034] Specifically, when the guardrail is installed, the base 1 and the installation position 6 reserved on the roadbed 7, the column 2 and the base 1, and the column 2 and each railing 3 are all disassembled and connected, so that the installation between the various structures of the guardrail is more flexible and adapts to different installation requirements. At this time, the base 1 and the installation position 6 reserved on the roadbed 7, the column 2 and the base 1, and the column 2 and each railing 3 are all locked by threaded fasteners 4, which makes disassembly and assembly more convenient, and can be disassembled and assembled without professional personnel, which is conducive to the installation of the guardrail and the subsequent maintenance and replacement, and can quickly replace the section when a part of the section is damaged, which is more convenient to operate.

[0035] More specifically, the columns 2 and the railings 3 are both tubular structures, so that the columns 2 and the railings 3 are both hollow structures, which can effectively reduce the overall weight of the guardrail, achieve lightweight guardrails, and reduce the burden on the roadbed 7. In addition, a protective cap 5 is installed on the upper end of each column 2. Preferably, the protective cap 5 is buckled on the outer side of the upper end of the corresponding column 2, and a plurality of first connecting holes are opened on the protective cap 5. At the same time, a plurality of second connecting holes corresponding to the first connecting holes are opened on the upper end of the corresponding column 2. When the protective cap 5 is installed on the column 2, a locking screw is provided between the first connecting hole and the corresponding second connecting hole. The upper end opening of the column 2 is sealed by the protective cap 5, which prevents water in the external environment from entering the hollow of the column 2 and causing internal corrosion. The protective effect is better and the service life of the guardrail is extended.

[0036] Figure 3 This is a structural diagram of each reserved installation position on the roadbed for installing a rail transit guardrail of the utility model. Figure 2 and Figure 3As shown, each reserved installation position 6 on the road base 7 includes a base plate 61 and a plurality of end threaded rods 62. The base plate 61 increases the structural strength of the area on the road base 7 for installing the base 1, and the supporting capacity is better, ensuring that the subsequent base 1 can be more stable after installation. In addition, a plurality of groups of through holes are provided on the base plate 61, and each group of through holes includes two through holes 611 arranged at intervals, which provides conditions for subsequent assembly with the same end threaded rod 62. At this time, each end threaded rod 62 is bent in a "U" shape, and both ends of each end threaded rod 62 are threaded ends 621, and each threaded end 621 is provided with a locking nut. When constructing the roadbed 7, the base plate 61 is placed on the surface of the roadbed 7, and each end threaded rod 62 is pre-buried in the roadbed 7, so that the threaded ends 621 at both ends of the end threaded rod 62 are extended upward to the outside of the roadbed 7. At the same time, the two threaded ends 621 extending out of the roadbed 7 are inserted into the two through holes 611 of the same group and locked by locking nuts. Since each end threaded rod 62 is bent and pre-buried in the roadbed 7, the installation strength and stability of the end threaded rod 62 itself are improved, so that the base 1 subsequently installed on the reserved installation position 6 can be more stable after installation.

[0037] Figure 4 This is a structural diagram of the base of a rail transit guardrail of the utility model. Figure 1 , Figure 2 as well as Figure 4 As shown, the base 1 installed on the installation position 6 reserved on the roadbed 7 includes a bottom plate 11, a sleeve 12 and a plurality of reinforcing ribs 13. During manufacturing, the sleeve 12 is arranged at the center of one surface of the bottom plate 11, and the bottom plate 11 and the bottom end of the sleeve 12 are fixedly connected to ensure that the sleeve 12 can be installed through the bottom plate 11. In addition, a plurality of reinforcing ribs 13 are arranged between the outer wall of the sleeve 12 and the bottom plate 11, and the connection strength between the sleeve 12 and the bottom plate 11 is improved by the reinforcing ribs 13, thereby improving the structural stability of the base 1. Preferably, the connection method of the bottom plate 11, the sleeve 12 and the reinforcing ribs 13 is welding connection, which is convenient for processing and reliable for connection. In addition, a plurality of mounting holes 111 are opened on the base plate 11, and the base plate 11 is installed on the mounting position 6 reserved on the foundation 7 through the mounting holes 111. At this time, the mounting holes 111 on the base plate 11 cooperate with the threaded ends 621 selected to be inserted into the through holes 611 on the base plate 61, and are locked by locking nuts to achieve the installation of the base 1 at the mounting position 6 reserved on the foundation 7.

[0038] More specifically, a through-hole 112 is provided in the center of the bottom plate 11. At this time, the through-hole 112 is connected to the barrel cavity of the sleeve 12, so that water from the external environment and the like that accidentally enters the column 2 during subsequent use can be discharged in time through the barrel cavity of the sleeve 12 and the through-hole 112, thereby avoiding corrosion and other problems caused by residues, and further extending the use requirements of the guardrail. At the same time, a plurality of spaced-apart pads 113 are provided on a surface of the bottom plate 11 away from the sleeve 12, and the bottom surface height of the bottom plate 11 is raised by the pads 113. At this time, the gaps between the two adjacent pads 113 are connected to the through-hole 112, that is, a connecting channel is formed between the bottom surface of the bottom plate 11 and the base plate 61 through the pads 113, which not only has a simple structure, but also facilitates the rapid discharge of substances that accidentally enter the column 2, further extending the service life of the guardrail.

[0039] More specifically, a plurality of adjustment holes 121 are provided on the side wall of the sleeve 12. At this time, the plurality of adjustment holes 121 are arranged at intervals in the length direction of the sleeve 12, so that after the base 1 is installed, the height of each adjustment hole 121 on the sleeve 12 is different. When the lower end of the column 2 is subsequently inserted into the sleeve 12, a matching hole 21 for use with the adjustment hole 121 can be provided on the side wall of the lower end of the column 2, so that during subsequent installation, the matching hole 21 at the lower end of the column 2 can select one of the adjustment holes 121 for matching installation, and the matching hole 21 and the corresponding adjustment hole 121 are connected and locked by the threaded fastener 4, so that when the column 2 is installed on the sleeve 12, different adjustment holes 121 can be selected to adjust the height of the column 2 installed on the sleeve 12, thereby adjusting the overall height of the guardrail to meet different installation requirements.

[0040] Figure 5 This is a structural diagram of a column of a rail transit guardrail of the utility model. Figure 1 , Figure 2 , Figure 4 as well as Figure 5As shown, a plurality of insertion holes 22 are provided on the side wall of the column 2 and on the side surface opposite to the adjacent column 2. At this time, the plurality of insertion holes 22 are arranged at intervals along the length direction of the column 2. At the same time, one end of a railing 3 is inserted into a insertion hole 22, that is, the insertion hole 22 provides convenience for the installation of the end of the railing 3 on the column 2. At the same time, a locking hole 23 connected to the corresponding insertion hole 22 is also provided on the side wall of the column 2 and located beside each insertion hole 22, that is, the component installed in the locking hole 23 can act on the corresponding insertion hole 22, which provides conditions for the subsequent restriction of the end of the railing 3 inserted into the insertion hole 22 through the locking hole 23. In addition, a locking hole 31 corresponding to the locking hole 23 is opened at the end of each railing 3. During subsequent installation, when the end of the railing 3 is inserted into the corresponding insertion hole 22, the locking hole 23 and the corresponding locking hole 31 can be aligned, and a threaded fastener 4 can be used to pass through the locking hole 23 and the corresponding locking hole 31 to connect and lock, thereby preventing the end of the railing 3 from escaping from the insertion hole 22 on the column 2, and the structural stability is higher.

[0041] Figure 6 This is a structural diagram of a railing for a rail transit guardrail of the utility model. Figure 1 , Figure 2 , Figure 5 as well as Figure 6 As shown, a limit block 24 arranged along the radial direction is provided on the inner wall of the column 2 and at the edge of each insertion hole 22. Preferably, the limit block 24 is welded to the inner wall of the column 2, so that the limit block 24 is stably installed on the column 2. At this time, one end of the limit block 24 is extended into the corresponding insertion hole 22, and only a small part of the limit block 24 is located in the corresponding insertion hole 22, so that the limit block 24 does not occupy too much space of the insertion hole 22. At the same time, a limiting notch 32 is also provided on the side wall at the end of the railing 3. At this time, when the end of the railing 3 is inserted into the corresponding insertion hole 22, the end of the limiting block 24 extending into the insertion hole 22 is inserted into the limiting notch 32, that is, when the railing 3 and the column 2 are installed, the circumferential rotation of the railing 3 can be limited by the cooperation of the limiting block 24 and the limiting notch 32, thereby ensuring that the clamping hole 31 can be quickly aligned with the locking hole 23 during installation, which is convenient for the installation of the threaded fastener 4 used to connect the clamping hole 31 and the locking hole 23, making disassembly and assembly more convenient and the installation efficiency higher.

[0042] More specifically, the handrail 3 preferably has a cylindrical rod structure, so that the surface of the handrail 3 is smoother. In addition, in the cross section of the handrail 3, the line connecting the center of the limiting notch 32 and the center of the handrail 3 is arranged perpendicular to the line connecting the center of the clamping hole 31 and the center of the handrail 3, so that in the circumferential direction of the handrail 3, the distance between the limiting notch 32 and the clamping hole 31 can be maximized, thereby ensuring the structural strength of the clamping hole 31 on the handrail 3 and ensuring that the handrail 3 can be stably installed on the column 2.

[0043] More specifically, each socket 22 on the column 2 is an elliptical structure. At this time, the long axis of each socket 22 is arranged along the length direction of the column 2. The elliptical socket 22 expands the size of the socket 22 in the length direction of the column 2, so that when the railing 3 is subsequently installed in the socket 22 on the column 2, the railing 3 can be tilted in the length direction of the column 2, thereby achieving slight angle adjustment and further improving the flexibility of the structure.

[0044] As a preferred embodiment, the opening at the end of each railing 3 is provided with an end curling edge bent toward the inside of the railing 3. At the same time, the orifice of each clamping hole 31 and the edge of the limiting notch 32 are provided with an auxiliary curling edge bent toward the inside of the railing 3. A water retaining structure is formed at the open part of the railing 3 by the end curling edge and the auxiliary curling edge, which prevents the water in the external environment from leaking from the socket 22 into the column 2 and then accidentally flowing into the railing 3 to corrode the railing 3, thereby extending the service life of the railing 3.

[0045] As a preferred embodiment, each pad 113 is provided with anti-slip teeth on the side facing away from the bottom plate 11, and when the bottom plate 11 contacts the base plate 61 through the pad 113, the anti-slip teeth are pressed against the base plate 61, so that when the base 1 is installed at the reserved installation position 6 through the threaded fasteners 4, the stability of the base 1 after installation can be improved through the anti-slip teeth, thereby further improving the protection effect of the guardrail.

[0046] The rail transit guardrail provided in this embodiment includes a base 1, a column 2 and a railing 3; the base 1 is installed at a reserved installation position 6 on the roadbed 7, and the lower end of the column 2 is installed on the base 1, and a plurality of railings 3 are arranged between two adjacent columns 2, and the two ends of the railing 3 are respectively installed on the corresponding two columns 2. In addition, the base 1 and the reserved installation position 6, the column 2 and the base 1, and the column 2 and the railing 3 are all disassembled and connected by threaded fasteners 4, which not only avoids the problem that the existing fixed welding structure cannot be adjusted, but also realizes flexible installation between structures, adapts to different installation requirements, improves structural flexibility, and can quickly realize the repair and replacement of damaged sections. At the same time, it can also avoid the problem that professional technicians are required to perform disassembly and assembly, and disassembly and assembly are more convenient, which is conducive to the installation of the guardrail and the subsequent maintenance and replacement, and reduces the cost of use.

[0047] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
