Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a power bracket for a railway comprises a supporting seat 1, wherein two threaded holes 2 are formed in the upper end of the supporting seat 1, a U-shaped frame 3 is inserted into the threaded holes 2, first external threads are respectively formed at both ends of the U-shaped frame 3, a pressure lever 6 is welded at one side of the upper end of the U-shaped frame 3, which is close to the supporting seat 1, an arc-shaped clamping plate 7 is arranged at one end of the pressure lever 6, which is close to the supporting seat 1, a first collar 4 is connected to both ends of the U-shaped frame 3 through threads, a second collar 5 is slidably sleeved outside the first collar 4, a second external thread matched with the threaded holes 2 is arranged on the outer wall of the second collar 5, a circular bottom plate 9 with a diameter larger than that of the second collar 5 is arranged at the bottom of both ends of the U-shaped frame 3, limiting grooves 10 are formed in the side walls of the first collar 4 and the second collar 5, and a limiting rod 11 is inserted into the limiting groove 10, the upper end of the supporting seat 1 is provided with a groove 8, and the groove 8 is positioned between the two threaded holes 2.

The diameter of the circular bottom plate 9 is smaller than that of the threaded hole 2, and the second sleeve ring 5 can be screwed into the threaded hole 2 through the second external thread by the design, so that the second sleeve ring 5 is tightly abutted to the circular bottom plate 9, and the effect of fixing the U-shaped frame 3 is better achieved.

Wherein, arc splint 7 is made by aluminium nitride ceramic material, arc splint 7 is provided with a plurality of evenly distributed's louvre, and aluminium nitride ceramic has better heat conductivity and insulating effect, because the inside long-term work of cable can produce the heat, consequently sets up the heat dissipation hole and can effectively dispel the heat that produces in the cable work process.

Wherein, first external screw thread and second external screw thread pitch are different, through setting up different pitches for first lantern ring 4 and second lantern ring 5 can not rotate simultaneously, let this kind of railway for electric power support when high frequency, violent vibration that the railway train process brought, the difficult production of screw thread is become flexible, have better stability.

Wherein, one of them is left-handed screw thread for first external screw thread and second external screw thread, and another is right-handed screw thread, through setting up the screw thread of equidirectional for first lantern ring 4 and second lantern ring 5 can not rotate simultaneously, let this kind of electric support for railway when the high frequency that the railway train process brought, violent vibration, the screw thread is difficult for producing not hard up, has better stability.

Wherein, the sticky insulating cushion 12 that is equipped with in the recess 8, because the support when carrying out the centre gripping to the cable, can be too tight to the cable centre gripping, through setting up insulating cushion 12, can reduce the cable and be extruded the possibility of excessive and damage.

The working principle is as follows: when the power support for the railway is used, the first lantern ring 4 is fixed at two ends of the U-shaped frame 3 through first external threads in a threaded connection mode, the second lantern ring 5 is sleeved outside the first lantern ring 4 in a sliding mode after the first lantern ring 4 is connected with the U-shaped frame 3, the connecting body of the U-shaped frame 3, the first lantern ring 4 and the second lantern ring 5 is inserted into the threaded hole 2, the second lantern ring 5 is fixed in the threaded hole 2 through second external threads in a connected mode, the diameter of the circular bottom plate 9 arranged at the bottom of the two ends of the U-shaped frame 3 is larger than that of the second lantern ring 5, when the second lantern ring 5 is connected in the threaded hole 2 in a threaded mode, the bottom of the second lantern ring 5 is tightly abutted against the circular bottom plate 9, at the moment, the limiting rod 11 is inserted into the limiting grooves 10 in the side walls of the first lantern ring 4 and the second lantern ring 5 to fix the first lantern ring 4 and the second lantern ring 5, and different first external threads and the limiting rod 11 are arranged to cooperate with each other, make first lantern ring 4 and second lantern ring 5 can not rotate simultaneously, wherein, because the setting of first external screw thread and second external screw thread, if when using this kind of power support, spacing groove 10 on first lantern ring 4 and the second lantern ring 5 takes place the dislocation, make gag lever post 11 can not accurately insert in the spacing groove 10, can freely adjust the position of U-shaped frame 3 through the screw thread, make gag lever post 11 accurately insert in the spacing groove 10 on first lantern ring 4 and the second lantern ring 5, reach two lantern ring pivoted effects of restriction, through the cooperation work between two external screw threads and two lantern rings, make it have better equipment stabilizing's effect when railway train process brings great vibration, prevent that equipment from becoming flexible and cable shift.

On the other hand, be close to 1 one end of supporting seat at depression bar 6 and set up arc splint 7, insert the in-process of screw hole 2 at 3 both ends of U-shaped frame, can freely adjust the position of arc splint 7, reach the better centre gripping effect to the cable, arc splint 7 through setting up the aluminium nitride ceramic material, because aluminium nitride ceramic has insulating nature good, good properties such as the heat conductivity is good, because the inside long-term work of cable can produce the heat, through setting up like this, can be better dispel the heat to the cable, play the effect of protective apparatus and cable.
