Description

Technical Field

[0001] The utility model relates to the field of pipeline clamps, and more specifically to a busbar limiting structure of a tubular busbar bridge. Background Art

[0002] The tubular busbar bridge is a transmission line structure composed of several tubular busbars fixed and installed by pipe clamps and brackets, among which the pipe clamps play a particularly important role in the limiting installation of the tubular busbars.

[0003] The outer side of the tubular busbar is usually covered with an insulating layer of rubber material. When installed with the existing pipeline clamp, the tubular busbar and the inside of the pipeline clamp are generally directly installed and connected through a sealing ring. Although such a connection and installation structure can ensure the stability of the installation limit structure of the tubular busbar, it lacks a corresponding telescopic structure. Even if the sealing ring at the connection can play a certain telescopic role, its telescopic performance is poor, which is not conducive to the expansion and contraction of the tubular busbar with the change of temperature. Over time, the risk of wear and tear at the connection increases. Therefore, we propose a busbar limit structure of a tubular busbar bridge to solve the above-mentioned problems.

[0028] Bolt holes 401 are provided at both ends of the upper arc-shaped clamp 4 and the lower arc-shaped clamp 5 , and the corresponding two bolt holes 401 on the upper arc-shaped clamp 4 and the lower arc-shaped clamp 5 are connected by connecting bolts 10 .

[0029] The use principle of the pipe clamp of the busbar limiting structure of this type of tubular busbar bridge is:

[0030] First, the pipeline clamp 2 is directly installed on the connecting rod 3 through the base 6, and then the arc-shaped sealing ring 7 is respectively inserted into the arc-shaped groove 501 of the upper arc-shaped clamp 4 and the lower arc-shaped clamp 5, and the arc-shaped sealing ring 7 is respectively in contact with the corresponding arc-shaped hanging pieces 8 on both sides of the arc-shaped groove 501, so that the supporting spring 9 supports the arc-shaped hanging piece 8, and then supports the arc-shaped sealing ring 7 from both sides, so that the arc-shaped sealing ring 7 has a certain offset space inside the arc-shaped groove 501, and then the tubular busbar 1 is clamped on the arc-shaped sealing ring 7 of the lower arc-shaped clamp 5, and the upper arc-shaped clamp 4 is clamped on the tubular busbar 1 through the arc-shaped sealing ring 7, and finally the corresponding upper arc-shaped clamp 4 and the lower arc-shaped clamp 5 are installed through the connecting bolts 10, thereby completing the installation of the tubular busbar 1;

[0031] When the external environment temperature changes and causes the tubular busbar 1 to expand thermally or contract coldly, the length of the tubular busbar 1 changes, which causes the connection of each connected pipeline clamp 2 to be pulled. At this time, the two arc-shaped sealing rings 7 sleeved on the tubular busbar 1 first act as the first layer of contraction structure, and then the connection of the arc-shaped suspension piece 8 presents the second layer of contraction structure, avoiding the risk of wear and tear of the insulating layer on the outside of the tubular busbar 1 at the connection due to rigid connection, thereby improving the safety of use.

[0032] Embodiment 2:

[0033] In view of the above embodiment 1, for further description, refer to Figure 3-Figure 5 The arc-shaped suspension piece 8 is an arc-shaped sheet structure integrally stamped from a metal material, and the outer shape structure of the arc-shaped suspension piece 8 is adapted to the inner wall structure of the arc-shaped groove 501; the ends of both ends of the arc-shaped sealing ring 7 are fixedly connected with protrusions 701 and recessed holes 702, and the connection between the two arc-shaped sealing rings 7 is clamped by the protrusions 701 and recessed holes 702; the arc-shaped sealing ring 7 is an arc-shaped structure integrally injection-molded from a rubber material, and the inner wall of the arc-shaped sealing ring 7 has a rough surface structure.

[0034] By adapting the outer structure of the arc-shaped suspension piece 8 to the inner wall structure of the arc-shaped groove 501, interference is avoided when the arc-shaped suspension piece 8 moves. By setting the protrusions 701 and the recessed holes 702 at both ends of the arc-shaped sealing ring 7, the structure of the connection between the two ends of the two arc-shaped sealing rings 7 can be made more stable, thereby forming a complete overall structure. By the rough surface structure of the inner wall of the arc-shaped sealing ring 7, the contact area between the tubular busbar 1 and the inner wall of the arc-shaped sealing ring 7 can be increased.
