[0023] like Figure 1 As shown, this embodiment provides a rail transit contact network double contact line positioning wire clamp, including a wire clamp main piece 1, a wire clamp auxiliary piece 2 and a connecting device; the wire clamp auxiliary piece 2 and the wire clamp main piece 1 are arranged at the same height, and the wire clamp auxiliary piece 2 and the wire clamp main piece 1 are detachably connected; the connecting device includes a first connecting device 3 and a second connecting device 4, the first connecting device 3 is arranged on the top of the wire clamp main piece 1, and the second connecting device 4 is arranged on the top of the wire clamp auxiliary piece 2, and the first connecting device 3 and the second connecting device 4 are detachably connected. The existing technology usually adopts double locators and double positioning wire clamps, and the positioning wire clamps are fixed by a threaded pair. Not only is the installation workload large, but the operation and maintenance costs are also high. Therefore, the utility model arranges the first connecting device 3 on the wire clamp main piece 1 and the second connecting device 4 on the wire clamp auxiliary piece 2. When the wire clamp main piece 1 and the wire clamp auxiliary piece 2 are spliced, the first connecting device 3 and the second connecting device 4 also complete the splicing installation work, which effectively improves the installation efficiency.

[0024] In a specific embodiment of the present disclosure, a first fixing device is provided on the side of the wire clamp main piece 1 close to the contact line 11, and a second fixing device is provided on the side of the wire clamp sub-piece 2 close to the contact line 11. The utility model is suitable for dual contact line scenarios. Compared with the prior art, there is no need to set up two sets of positioners and positioning wire clamps, only one set of structure is required, which reduces material consumption.

[0025] like Figure 2As shown, in a specific embodiment of the present disclosure, the first fixing device includes a first sub-fixing device 5 and a second sub-fixing device 6, and the first sub-fixing device 5 and the second sub-fixing device 6 are respectively arranged on both sides of the line clamp main plate 1, and the second fixing device includes a third sub-fixing device 7 and a fourth sub-fixing device 8, and the third sub-fixing device 7 and the fourth sub-fixing device 8 are respectively arranged on both sides of the line clamp auxiliary plate 2, and the first sub-fixing device 5 is provided with a first groove on the side close to the contact line 11, and the third sub-fixing device 7 is provided with a second groove on the side close to the contact line 11, and the first groove and the second groove form an arc groove 9, and the first groove is perpendicular to the contact line 11. The direction of the contact wire 11 only wraps half of the cross-section of the contact wire 11. The second groove is set in the same form as the first groove. The first groove and the second groove are set opposite to each other. When the wire clamp main piece 1 and the wire clamp auxiliary piece 2 are spliced, the first groove and the second groove together form an arc groove 9. The arc groove 9 matches the entire cross-section of the contact wire 11 and is used to fix the connection with the contact wire 11. It should be noted that the left side of the first sub-fixing device 5 and the second sub-fixing device 6 set on the wire clamp main piece 1 is a cover plate. When the third sub-fixing device 7 and the fourth sub-fixing device 8 set on the wire clamp auxiliary piece are spliced, the top of the third sub-fixing device 7 and the fourth sub-fixing device 8 are fitted with the cover plate.

By inserting the safety pins 12 into the pin holes and passing through the entire positioning wire clamp, a fixed connection of the double contact line positioning wire clamp is achieved.

[0027] In a specific embodiment of the present disclosure, the first connecting device 3 and the second connecting device 4 form a cylindrical groove.

[0028] In a specific embodiment of the present disclosure, a boss 10 is provided at the end of the first connecting device 3, and a third groove is provided at the end of the second connecting device 4. The width of the boss 10 is the same as the depth of the third groove. The first connecting device 3 and the second connecting device 4 are connected by mortise and tenon joints, which improves the stability of the positioning wire clamp while simplifying the structural form of the double contact line positioning wire clamp. The original threaded pair is changed to the current threadless pair. The overall performance of the wire clamp meets the mechanical and electrical performance requirements specified by the standard and has good anti-fatigue performance.
