Description

Technical Field

[0001] This utility model relates to the field of lightning protection wire technology, and in particular to a lightning protection wire raised shoulder frame type lower anchor base. Background Technology

[0002] For existing high-speed railways, lightning protection wires are added. The lightning protection wires are anchored downwards and at the terminal on existing anchor columns or middle anchor columns. Anchor angle steel is used to anchor the wires at the top of the columns. In some sections (compensation positions, middle anchor positions, and special equipment positions), the existing anchoring method cannot guarantee the insulation distance between the lightning protection wires and existing middle anchors, compensation position catenary cables, and AF lines in special equipment position sections. Extreme weather conditions such as strong winds or icing can easily cause discharge between the lightning protection wires and live conductors, burning existing equipment. Utility Model Content

[0003] This utility model proposes a raised shoulder-type lower anchor base for lightning protection wires, which solves the problem in the prior art that extreme weather such as strong winds or icing can easily cause discharge between the lightning protection wire and the live conductor, burning existing equipment.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A lightning protection wire raised shoulder type lower anchor base includes a lower column and a lower anchor raised shoulder. The lower anchor raised shoulder is installed on the top of the lower column, and two lower anchor terminal connecting rings are symmetrically installed on the upper parts of both sides of the lower anchor raised shoulder.

[0006] Furthermore, the lower anchor terminal connecting ring has a circular hole.

[0007] Furthermore, a support is provided on the top side of the lower anchor raising shoulder frame located between the two lower anchor terminal connecting rings.

[0008] Furthermore, the bottom of the lower anchor heightening shoulder frame is installed on the top of the lower column via a mounting base. The mounting base includes a side plate and a bottom plate. Two side plates are provided, and the two side plates are symmetrically fixed to both sides of the lower column. The bottom plate is fixed to the top of the two side plates, and the bottom end of the lower anchor heightening shoulder frame is fixed to the top of the bottom plate.

[0009] Furthermore, the bottom of the outer side of the lower anchor heightening shoulder frame is provided with several ribs, the sides of the ribs are fixed to the lower anchor heightening shoulder frame, and the bottom ends of the ribs are fixed to the base plate.

[0010] Furthermore, two fixing components are symmetrically arranged on the two sides of the lower anchor heightening shoulder frame. The fixing components include an extension column, a mounting plate, an inner clamping plate, an outer clamping plate, and fixing bolts. The extension column is installed on the side of the lower anchor heightening shoulder frame, and the mounting plate is fixed to the end of the extension column away from the lower anchor heightening shoulder frame. The inner clamping plate is installed on the mounting plate, and the outer clamping plate is installed on the inner clamping plate by two fixing bolts. The outer clamping plate is provided with an arc-shaped protrusion.

[0011] Furthermore, the inner clamping plate is rotatably mounted on the mounting plate, and two fixing plates are symmetrically fixed to the upper and lower sides of the inner clamping plate, with a fastening stud screwed onto each fixing plate.

[0012] Furthermore, the fixing assembly also includes an insulating protective assembly, which includes an insulating protective cover, an elastic telescopic rod, and a limiting sleeve. The insulating protective cover is provided with a notch that matches the inner clamping plate and the fixing piece. The protective cover is fixed to the edge of the inner clamping plate and the fixing piece. The opening of the protective cover faces the outer clamping plate. Two stabilizing components are symmetrically fixed to the upper and lower sides of the insulating protective cover.

[0013] Furthermore, the stabilizing component includes two symmetrically arranged elastic telescopic rods, which are symmetrically fixed to the two side plates of the insulating protective cover, and a limiting sleeve is connected between the telescopic ends of the two elastic telescopic rods.

[0014] The positive effects of this utility model are as follows: it satisfies the insulation distance between the lower anchor position and the middle anchor, AF line, catenary, etc., and ensures the safe distance between the lightning protection wire and the live conductor under conditions such as strong winds and icing. This ensures the safety, reliability, and stability of the power supply of the contact network system. At the same time, increasing the height of the lightning protection wire in the span of the shoulder frame anchor increases the protection range of the lightning protection wire for the contact network, further improving the lightning protection effect of this span, reducing operation and maintenance costs, and ensuring the efficient operation of the high-speed railway.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1

[0024] Combination Figure 1-5 As shown, a lightning protection wire raised shoulder type lower anchor base includes a lower column 1 and a lower anchor raised shoulder 4. The lower anchor raised shoulder 4 is installed on the top of the lower column 1, and two lower anchor terminal connecting rings 6 are symmetrically installed on the upper parts of both sides of the lower anchor raised shoulder 4.

[0025] The anchor terminal connecting ring 6 has a round hole.

[0026] A support 8 is provided on the top side of the lower anchor raising shoulder frame 4, located between the two lower anchor terminal connecting rings 6.

[0027] The bottom of the lower anchor heightening shoulder frame 4 is installed on the top of the lower column 1 via a mounting base. The mounting base includes a side plate 2 and a bottom plate 3. There are two side plates 2, which are symmetrically fixed to both sides of the lower column 1. The bottom plate 3 is fixed to the top of the two side plates 2. The bottom end of the lower anchor heightening shoulder frame 4 is fixed to the top of the bottom plate 3.

[0028] The bottom of the outer side of the lower anchor heightening shoulder frame 4 is provided with several ribs 5. The side of the ribs 5 is fixed to the lower anchor heightening shoulder frame 4, and the bottom end of the ribs 5 is fixed to the bottom plate 3.

[0029] Technical solution: The structure of this utility model includes: a lower anchor heightening shoulder frame 4, a support column connecting base plate 3, a support column connecting side plate 2, a column top arch support 8, and necessary bolts for installation.

[0030] In this embodiment, the working principle of the lightning protection wire raised shoulder frame type lower anchor base is as follows:

[0031] First, the lower anchoring and heightening shoulder frame 4 has a certain height. It is installed on the top of the lower column 1, and then the lightning protection wire is installed on the support 8, which increases the insulation distance between the lightning protection wire and the existing live body below. At the same time, the lower anchoring terminal connecting rings 6 on both sides of the lower anchoring and heightening shoulder frame 4 provide the anchoring conditions for the lightning protection wire, and realize the lower anchoring fixation. The lower anchoring and heightening shoulder frame 4 is fixed by using the side plate 2, the bottom plate 3 and the corresponding bolts.

[0032] Functions of each part of the lightning protection wire raising shoulder frame type lower anchor base:

[0033] The anchor heightening shoulder frame has four functions: using 100*100*10 square steel to increase the anchor height of the lightning protection line, ensuring the insulation distance between it and the middle anchor, AF line, and catenary.

[0034] Anchor terminal connecting ring 6: It uses the connecting rings at both ends to connect with the existing single-ear connecting plate of the anchor, thus completing the original function of anchoring at the top of the column using the anchor angle steel.

[0035] Base plate 3: The square steel of the heightening shoulder frame is fixed to the top of the column using four adjustment holes and triangular plate support, which serves to connect the heightening shoulder frame and the side plate of the column.

[0036] Side plate 2: It is connected to the base plate with 4 bolts and to the support column with 4 bolts, which serves to fix the base plate of the support column.

[0037] Support 8 is the column top and bow support: a lightning protection wire support is installed at the support position to fix the lightning protection wire, which serves to fix the lightning protection wire at the bow position.

[0038] Example 2

[0039] Combination Figure 1-5 As shown, the difference between this embodiment and embodiment 1 is that two fixing components are symmetrically arranged on the two sides of the lower anchor heightening shoulder frame 4. The fixing components include an extension column 9, a mounting plate 10, an inner clamping plate 11, an outer clamping plate 12, and fixing bolts 13. The extension column 9 is installed on the side of the lower anchor heightening shoulder frame 4. The mounting plate 10 is fixed to the end of the extension column 9 away from the lower anchor heightening shoulder frame 4. The inner clamping plate 11 is installed on the mounting plate 10. The outer clamping plate 12 is installed on the inner clamping plate 11 by two fixing bolts 13. The outer clamping plate 12 is provided with an arc-shaped protrusion.

[0040] The inner clamping plate 11 is rotatably mounted on the mounting plate 10. Two fixing plates 14 are symmetrically fixed to the upper and lower sides of the inner clamping plate 11, and a fastening stud 15 is screwed onto each fixing plate 14.

[0041] First, the lightning protection wire is installed between the inner clamping plate 11 and the outer clamping plate 12. The extension post 9 keeps the installation position of the lightning protection wire away from the lower anchor heightening shoulder 4, further improving the insulation distance and ensuring safety. In order to make the installation of the lightning protection wire adaptable to various installation angles, the inner clamping plate 11 and the outer clamping plate 12 can be rotated and adjusted to any angle on the mounting plate 10. After rotating to the appropriate position, the fastening stud 15 is rotated and will abut against the surface of the mounting plate 10 to achieve fixation and prevent rotation and displacement during use.

[0042] Example 3

[0043] Combination Figure 1-5 As shown, the difference between this embodiment and embodiment 2 is that the fixing component also includes an insulating protective component. The insulating protective component includes an insulating protective cover 16, an elastic telescopic rod 17, and a limiting sleeve 18. The insulating protective cover 16 is provided with a notch that matches the inner clamping plate 11 and the fixing piece 14. The protective cover 16 is fixed to the edge of the inner clamping plate 11 and the fixing piece 14. The opening of the protective cover 16 faces the outer clamping plate 12. Two stabilizing components are symmetrically fixed to the upper and lower sides of the insulating protective cover 16.

[0044] The stabilizing component includes two symmetrically arranged elastic telescopic rods 17, which are symmetrically fixed to the two side plates of the insulating protective cover 16. A limiting sleeve 18 is connected between the telescopic ends of the two elastic telescopic rods 17.

[0045] To further improve insulation, an insulating protective cover 16 was designed. When installing the lightning protection wire, the lightning protection wire passes through the limiting sleeve 18, and then the entire lightning protection wire is blocked inside the insulating protective cover 16, making it difficult to generate arc discharge with the outside. During use, if the lightning protection wire is shaken by external force, the elastic telescopic rod 17 can absorb and buffer it, ensuring the stability of the lightning protection wire.
