DETAILED DESCRIPTION

[0038] The technical solutions of the present application will be described in detail below in conjunction with the specific embodiments. However, it should be understood that the elements, structures and features in one embodiment can be beneficially combined into other embodiments without further description.

Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features.

[0040] In the description of the present application, it should be understood that the terms "up", "down", "bottom", "inner" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in Figure 1, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0041] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] The steel wire rope 200 in the present application mainly refers to a rope with a certain rigidity, which is easy to expand in a natural state; for example, it can be made of pure steel wire, or it can be made of steel wire mixed with other materials.

[0043] As shown in Figures 1-6, the first embodiment of the present application provides a steel wire rope column 100 (which can be simply referred to as column 100), which extends in the longitudinal direction, and the bottom can be installed on the ground or other structures through a base 101, etc. The top is provided with a cap 102, which can cover the top end of the column to block the internal structure.

[0044] The column 100 has a column wall 1; the interior of the column is a hollow structure 2 surrounded by the column wall 1. When the cross section of the column wall 1 is rectangular, the cross section of the hollow structure 2 is also approximately rectangular; as shown in FIGS. 2-4, the column wall 1 is approximately square, which is a commonly used shape; when the cross section of the column wall 1 is circular, the cross section of the hollow structure 2 is also approximately circular.

[0045] When the column wall 1 is rectangular, it has two adjacent edges, i.e., a first edge 31 and a second edge 32, which are connected at a corner 4.

[0046] In this application, various terms such as shapes and edges are described mainly in terms of the cross section of the column 100, which is easy to understand in conjunction with the drawings.

[0047] The column wall 1 is provided with two through holes, i.e., a first through hole 51 and a second through hole 52, at the same height in the longitudinal direction, which connect the interior and the exterior of the column, and are used for the entry and exit of the steel wire rope 200, respectively.

[0048] The distance from the corner 4 to the first through hole 51 is approximately equal to the distance from the corner 4 to the second through hole 52, so as to facilitate the installation of the steel wire rope 200. When the column wall 1 is square, the first through hole 51 is approximately located in the middle of the first edge 31, and the second through hole 52 is approximately located in the middle of the second edge 32.

[0049] As shown in FIGS. 2, 3, 5 and 6, the steel wire rope column 100 further comprises a clamping strip 6 located in the interior of the column and connected to the column wall 1. The clamping strip 6 is a long strip extending in the longitudinal direction, and its cross section has two ends, i.e., a first end 61 and a second end 62, which are oppositely arranged, and a protruding portion 63 located between the two ends. Among them, the first end 61 of the clamping strip is located on the column wall 1 between the corner 4 and the first through hole 51, and the second end 62 of the clamping strip is located on the column wall 1 between the corner 4 and the second through hole 52. After the steel wire rope 200 passes through the column 100, the protruding portion 63 faces away from the corner 4 and faces the steel wire rope 200 to support the steel wire rope.

[0050] In an embodiment, the clamping strip 6 is in sliding connection with the column wall 1 in the longitudinal direction. The clamping strip 6 is configured to be installed between the steel wire rope 200 and the corner 4 after the steel wire rope 200 passes through the column 100, and the protruding portion 63 faces the steel wire rope to support the steel wire rope, as shown in FIG. 6.

[0051] In a specific embodiment, a first sliding groove 71 extending longitudinally is arranged between the corner 4 and the first through hole 51 on the column wall 1, and is located inside the column; a second sliding groove 72 extending longitudinally is arranged between the corner 4 and the second through hole 52, and is parallel to the first sliding groove 71 and also located inside the column. Relative to the corner 4, the first sliding groove 71 is close to the first through hole 51 and can be arranged adjacent to the first through hole 51; relative to the corner 4, the second sliding groove 72 is close to the second through hole 52 and can be arranged adjacent to the second through hole 52. Such an arrangement can enable the subsequent clamping strip 6 to be closer to the middle of the column interior, so as to better support the steel wire rope 200. The first end 61 and the second end 62 of the clamping strip 6 are respectively provided with a first sliding block 64 and a second sliding block 65, which are respectively matched with the first and second sliding grooves 71, 72 to realize the sliding of the clamping strip 6 along the column wall 1. The clamping strip 6 is configured such that, after the steel wire rope 200 passes through the column 100, the first and second sliding blocks 64, 65 at the two ends of the clamping strip 6 are installed between the steel wire rope 200 and the corner 4 through the first and second sliding grooves 71, 72, and the protruding portion 63 faces the steel wire rope 200 to support the steel wire rope. In another embodiment, the sliding groove and the sliding block can also be arranged in an exchanged position, for example, the sliding groove is arranged on the first end 61 and the second end 62 of the clamping strip 6, and the sliding block is arranged on the column wall 1, which is easy to understand. The clamping strip 6 can have a symmetrical structure, and in use, it can be connected to the column wall 1 in a sliding manner without distinguishing the upper and lower directions, facilitating installation.

[0052] The protruding portion 63 is in a circular arc shape, and when the column wall 1 is rectangular, the circular arc shape occupies approximately one quarter or more than one quarter of the entire circle where it is located; the protruding portion 63 is configured such that, when supporting the steel wire rope, the steel wire rope 200 is substantially perpendicular to the first side 31 and the second side 32, as shown in FIG. 6.

[0053] When the steel wire rope is bent, it will naturally expand to both sides due to its strong toughness; since the first through hole 51 and the second through hole 52 for the steel wire rope to pass through are larger than the arc-shaped pipe 300 (an installation tool for guiding the steel wire rope 200 to pass through the column 100) used for the steel wire rope 200, and are necessarily larger than the diameter of the steel wire rope 200, therefore, without the pushing constraint of the protruding portion 63, the steel wire rope is difficult to form a 90° turn at the column, resulting in problems such as difficulty in installation of the steel wire rope or low installation accuracy. The arc-shaped pipe 300 can use the conventional arc-shaped pipe for installing the steel wire rope in the prior art, and its structure can refer to FIG. 7, which is a curved tubular structure having an open end 301 for the end of the steel wire rope 200 to be inserted into the interior of the arc-shaped pipe, and a sharp end 302 for guiding the steel wire rope 200 to pass in; the open end 301 and the sharp end 302 are divided into two opposite ends.

[0054] In addition, when the steel wire rope 200 is installed in the post, it is difficult to install the steel wire rope due to the blocking effect of the buckle strip 6. At this time, the installation tool (the tip 302 of the arc-shaped tube 300) is difficult to align with each through hole 51, 52, so that the installation is difficult and the efficiency is low. The detachable buckle strip 6 provided by some embodiments of the present application is slid and inserted after the steel wire rope 200 is installed, which leaves more space for the installation of the steel wire rope, so that the installation tool is more easily aligned with each through hole 51, 52, and the installation efficiency is greatly improved. Moreover, the steel wire rope can be smoothly transitioned without creases after installation. The cap 102 at the top of the post can be buckled at the top of the post after the buckle strip 6 is installed, so as to fix the buckle strip 6 in the post 100 and prevent external personnel from accessing the interior, or the buckle strip 6 is slid after installation.

[0055] In an embodiment, a through hole 53 is further provided on the post wall 1 opposite to the first through hole 51 or the second through hole 52, which can be used for the steel wire rope 200 to pass in and out, so as to realize the installation of the steel wire rope 200 by 180°; and the post 100 becomes a universal post of 90° and 180°. As shown in FIG. 4, the through hole 53 is arranged opposite to the first through hole 51 and is substantially on a straight line.

[0056] In an embodiment, as shown in FIG. 1 and FIG. 6, a plurality of groups of the first through hole 51, the second through hole 52 and the through hole 53 are arranged on the post wall 1 in the longitudinal direction, so that a plurality of steel wire ropes 200 can be installed in the longitudinal direction, and the safety of the steel wire rope as a guardrail is increased.

[0057] In an embodiment, as shown in FIG. 3 and FIG. 4, an arc-shaped reinforcing rib 8 can be further arranged in the post wall 1 between the corner 4 and the buckle strip 6, so as to enhance the strength of the post wall 1 and not to interfere with the passing in and out of the steel wire rope 200. Obviously, the radius of the reinforcing rib 8 is smaller than the radius of the protruding part 63 of the buckle strip 6. The post wall 1 and the reinforcing rib 8 can be an integrally formed plate structure made of metal materials such as stainless steel. The buckle strip 6 can also be made of a metal plate, which can firmly and reliably support the steel wire rope 200 and is not easy to deform.

[0058] The second embodiment of the present application provides a method for installing a steel wire rope 200, which adopts the steel wire rope post 100 of any of the foregoing embodiments. The method comprises the following steps:

[0059] The bottom (base 101) of the post 100 is fixedly installed by bolts or the like, for example, on the ground;

[0060] One end of the steel wire rope 200 is inserted into the arc-shaped tube 300 (mounting tool), the arc-shaped tube 300 drives the steel wire rope 200 to pass through the first through hole 51 and then pass out from the second through hole 52, the arc-shaped tube 300 is removed, and the installation of the steel wire rope 200 is adjusted; at this time, the protruding part 63 of the buckle strip abuts against the steel wire rope 200, so that the steel wire rope 200 is bent by 90°, as shown in Fig. 6.

[0061] In an embodiment, when the buckle strip 6 is in sliding connection with the column wall 1, the mounting method comprises the following steps:

[0062] The bottom (base 101) of the column 100 is fixedly mounted by bolts or the like, for example, on the ground;

[0063] One end of the steel wire rope 200 is inserted into the arc-shaped tube 300, the arc-shaped tube 300 drives the steel wire rope 200 to pass through the first through hole 51 and then pass out from the second through hole 52;

[0064] The arc-shaped tube 300 is removed, the position of the steel wire rope 200 in the column is adjusted, and then the buckle strip 6 is slidably inserted from the top to the bottom of the column, so that the protruding part 63 of the buckle strip abuts against the steel wire rope 200 and makes the steel wire rope 200 bent by 90°, as shown in Fig. 6; the cap 102 is buckled on the top of the column to fix the buckle strip 6.

[0065] Finally, it should be noted that: in the present specification, each embodiment is described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same or similar parts of each embodiment can be referred to each other. The described order is also not an absolute order, and can be adjusted according to the actual installation, for example, in some occasions, the steel wire rope can be installed on the column 100 first, and then the column 100 is fixedly installed on the ground, etc.

[0066] The described embodiments are only used to describe the preferred embodiments of the present application, and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements of the technical solutions of the present application made by those skilled in the art shall fall within the protection scope determined by the claims of the present application.
