Description

Technical Field

[0001] This utility model relates to the field of contact wire accessories technology, and in particular to a modular quick-install AF line suspension column connection structure. Background Technology

[0002] In electrified railway or urban rail transit systems, AF line (positive feeder) bollards are important components for supporting and fixing the AF line, and the stability and ease of their installation directly affect the efficiency of construction and maintenance.

[0003] Currently, most existing AF line bollards adopt a one-piece structure design. While this one-piece structure ensures overall strength to a certain extent, its large size makes hoisting, positioning, and installation extremely inconvenient due to tunnel space constraints. Installers must perform complex operations in confined spaces, increasing installation difficulty and labor intensity, potentially leading to decreased installation accuracy, and even safety accidents due to improper operation. Furthermore, any partial damage to the one-piece structure often requires complete replacement, resulting in high maintenance costs. Therefore, developing an AF line bollard connection structure that is easy to install and maintain is of significant practical importance. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a modular quick-install AF line hanging column connection structure to solve the problems mentioned in the background art.

[0005] To achieve the above technical objectives, the present invention provides a modular quick-install AF line suspension column connection structure, comprising: a base, a suspension rod, and an insulator. The suspension rod is disposed between the base and the insulator. One end of the insulator is provided with a cable clamp. The base includes a flange, and a connecting ring is provided on the flange. An anchoring groove is provided on the inner ring surface of the connecting ring. One end of the suspension rod is provided with an anchoring mechanism, and the other end is connected to the insulator. A pushing device is provided inside the connecting ring, and the pushing device cooperates with the anchoring mechanism to fix it in the anchoring groove.

[0006] Furthermore, the anchoring mechanism includes a top cover with a through hole that cooperates with the pushing device. Both the top cover and the lifting rod are provided with a plurality of opposing connecting columns arranged in a circumferential array. An arc-shaped push block is provided between two adjacent connecting columns. A push rod along the radial direction of the lifting rod is provided on the inner side of the arc-shaped push block. The push rod is provided with a telescopic hole. A positioning rod is provided between two adjacent connecting columns. The positioning rod passes through the telescopic hole and is provided with a tension spring. The two ends of the tension spring are respectively connected to the end wall of the positioning rod and the telescopic hole.

[0007] Furthermore, the pushing device includes a base, on which a pushing block is provided. The pushing block has several arc-shaped protrusions arranged in a circular array around the base, and the through hole cooperates with the pushing block.

[0008] Furthermore, the upper circumferential array of the connecting ring has several guide posts, and the outer cylindrical surface of the hanger is provided with an L-shaped guide groove, the top of the vertical section of the L-shaped guide groove penetrating the top cover.

[0009] Furthermore, the guide post includes a housing threadedly connected to the connecting ring, and a spring and a locking tongue are provided inside the housing. The end of the horizontal section of the L-shaped guide groove is provided with a locking groove that cooperates with the locking tongue.

[0010] Furthermore, the insulator is hinged to the rod, a locking block is provided on one side of the rod, a positioning rod and a locking groove are provided on the insulator, the locking groove cooperates with the locking block, and a positioning groove that cooperates with the positioning rod is provided at the lower end of the rod.

[0011] Compared with the prior art, the beneficial effects of this utility model include:

[0012] 1. This utility model achieves initial positioning through the precise cooperation between the guide column on the base and the L-shaped guide groove of the hanger rod. Then, the jacking device pushes the arc-shaped push block into the anchoring ring groove to complete the firm fixation. At the same time, the insulator and the hanger rod adopt a convenient connection method of positioning rod, locking block and locking groove. This design greatly simplifies the installation steps. Ordinary workers can quickly complete the installation after simple training, which significantly improves the installation efficiency, reduces labor and time costs, and makes the laying of AF line hanger rods more efficient.

[0013] 2. The components of this utility model, such as the suspension rod and insulator, can be disassembled and replaced independently. When local damage occurs, the damaged component can be easily removed by dismantling the guide column and pushing the jacking device in the reverse direction. After replacing the new component, it can be reinstalled according to the procedure. At the same time, the cooperation between the arc-shaped push block and the anchoring ring groove, as well as the locking design between the guide column and the locking groove, ensure the stability of the structure, which can withstand various external forces during the operation of the AF line, reduce failures caused by structural loosening, greatly reduce maintenance costs, and improve structural reliability.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Reference Figure 1 This utility model provides a modular quick-install AF line hanger connection structure, including a base 1, a hanger 2 and an insulator 3. The hanger 2 is disposed between the base 1 and the insulator 3. One end of the insulator 3 is provided with a cable clamp 4 for clamping and fixing the AF line.

[0021] Reference Figure 2 , Figure 3 The base 1 includes a flange 101, on which a connecting ring 102 is provided. An anchoring groove 103 is provided on the inner ring surface of the connecting ring 102, and a plurality of guide posts 106 are arranged in a circular array on the upper part of the connecting ring 102. Each guide post 106 specifically includes a housing 107 threadedly connected to the connecting ring 102, and a spring 108 and a locking tongue 109 are provided inside the housing 107. A pushing device is provided inside the connecting ring 102, and the pushing device includes a base 104, on which a push block 105 is provided, and a plurality of arc-shaped protrusions are arranged in a circular array around the base 104.

[0022] In the actual installation process, the base 1 is first fixed to the top of the tunnel or other preset installation position by means of flange 101, ensuring that flange 101 fits tightly with the installation surface, and flange 101 is firmly fixed with appropriate bolts to ensure the stability of base 1.

[0023] Reference Figure 4A top cover 202 is installed at the upper end of the lifting rod 2. The top cover 202 has a through hole 209 that mates with the push block 105. Both the top cover 202 and the lifting rod 2 have several opposing connecting posts 204 arranged in a circular array. An arc-shaped push block 203 is provided between two adjacent connecting posts 204. A push rod 205 along the radial direction of the lifting rod 2 is provided on the inner side of the arc-shaped push block 203. The push rod 205 has a telescopic hole 206. A positioning rod 207 is provided between two adjacent connecting posts 204. The positioning rod 207 passes through the telescopic hole 206 and is provided with a tension spring 208. The two ends of the tension spring 208 are connected to the end walls of the positioning rod 207 and the telescopic hole 206, respectively.

[0024] The outer cylindrical surface of the hanger 2 is provided with an L-shaped guide groove 210, and the top of the vertical section of the L-shaped guide groove 210 penetrates the top cover 202. When connecting the boom 2 to the base 1, align the vertical section of the L-shaped guide groove 210 of the boom 2 with the guide post 106 on the connecting ring 102, and slowly lift the boom 2 so that the guide post 106 slides along the vertical section of the L-shaped guide groove 210. At the same time, the push block 105 passes through the through hole 209 on the top cover 202. After lifting to a certain position, rotate the boom 2 so that the guide post 106 enters the horizontal section of the L-shaped guide groove 210. Continue to rotate the boom 2 so that the arc-shaped protrusion on the push block 105 contacts the end of the push rod 205, thereby pushing the arc-shaped push block 203 to expand outward to overcome the tension of the tension spring 208, and so that the arc-shaped push block 203 is inserted into the anchoring ring groove 103 on the inner ring surface of the connecting ring 102, thereby firmly fixing the boom 2 to the base 1. In practical applications, an elastic material, such as rubber, can be set on the outer arc surface of the arc-shaped push block 203.

[0025] When the guide post 106 reaches the end of the horizontal section of the L-shaped guide groove 210, the locking tongue 109 inside the guide post 106 pops out under the action of the spring 108 and gets into the locking groove 211 at the end of the horizontal section of the L-shaped guide groove 210, thus completing the connection and locking between the rod 2 and the base 1.

[0026] Reference Figure 1 , Figure 5 The insulator 3 is hinged to the hanger 2. A locking block 201 is provided on one side of the hanger 2. The insulator 3 is provided with a positioning rod 301 and a locking groove 302. The lower end of the hanger 2 is provided with a positioning groove that cooperates with the positioning rod 301. When connecting the hanger 2 to the base 1, the insulator 3 is folded upward so that the locking block 201 engages with the locking groove 302. At this time, the folded insulator 3 is perpendicular to the axis of the hanger 2, and the insulator 3 can be used as a force-adding rod to facilitate the rotation of the hanger 2.

[0027] After the suspension rod 2 is fixed, the insulator 3 is restored to be coaxial with the suspension rod 2. The positioning rod 301 is aligned with the positioning groove at the lower end of the suspension rod 2 and inserted into the positioning groove, thereby fixing the insulator 3.
