Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.

As shown in figure 1, the segmented component of the JSGT steel rail type steel body trolley line comprises two insulating clamping plates 7 which are oppositely arranged, wherein the two insulating clamping plates are respectively positioned at two sides of the waist part 5 of the trolley line, the insulating clamping plates are fixedly connected with the waist part of the trolley line through fastening bolts 2, and the outer side surfaces of the insulating clamping plates are flush with the outer side surfaces of the trolley line.

The insulating splint 7 is an epoxy resin insulating plate to improve the wear resistance and the insulating property and prolong the service life. Specifically, insulating splint include the connecting plate 4 that extends along wiping line length direction and upwards extend to wiping line segmentation clearance's division board 3 from the middle part of connecting plate 4, the upper surface of division board 3 and the upper surface of wiping line 1 are located same height, the upper surface of two division boards form with the contact surface of driving current collector slider, the division board is along wiping line length direction's both ends respectively with the two wiping line contact of segmentation clearance both sides, avoid having the clearance between segmentation part and the wiping line, thereby make the current collector slide more steadily, and slowed down the local wear of wiping piece, as shown in fig. 3, both ends corner sets up the circular arc chamfer around the division board upper edge, make insulating splint's installation more convenient.

The fastening bolts penetrate through the connecting plates on two sides below the partition plate, so that the distance between the two groups of fastening bolts is increased, and the fixing reliability is improved.
