The shoulder rest main body 1 comprises a shoulder rest transverse section 11 and a shoulder rest vertical section 12. The shoulder frame transverse section 11 is obliquely arranged, the shoulder frame vertical section 12 is vertically arranged, and the shape of the shoulder frame transverse section 11 is matched with that of the tunnel lining. The middle part of the shoulder frame transverse section 11 is vertically connected with a connecting angle steel 2, and one side of the shoulder frame vertical section 12 far away from the connecting angle steel 2 is connected with a flange plate 3. The shoulder frame transverse section 11 is provided with a plurality of first mounting holes 13, the connecting angle steel 2 is provided with a plurality of second mounting holes 21, and the flange plate 3 is provided with a plurality of third mounting holes 31. The shoulder frame cross section 11 is used for connecting a tunnel, the connecting angle steel 2 is used for installing a protecting wire clamp and a short-circuit wire, and the flange plate 3 is used for installing a positive feeder insulator. More specifically, the protection wire clip and the shorting wire are mounted in the second mounting hole 21, and the positive feeder insulator is mounted in the third mounting hole 31. After the arrangement, the positive feeder line and the protection line can be arranged on the shoulder frame, the problem of dispersion of installation mode components in the prior art is solved, and the construction and installation efficiency can be greatly improved. And the structure is simple, and the construction cost can be reduced.
In the present embodiment, as shown in fig. 2, a plurality of first mounting holes 13 are distributed along the length direction of the shoulder frame cross section 11. A plurality of bolts connect the shoulder frame cross section 11 with the tunnel lining through the first mounting holes 13. When the tunnel lining is provided with the pre-buried channel, a T-shaped bolt can be used; when the tunnel lining is not provided with the embedded channel, the anchor bolt can be used for post-planting.
Specifically, as shown in fig. 3, the second mounting holes 21 are distributed along the length direction of the angle steel 2. The plurality of second mounting holes 21 are used for mounting the protection wire clip and the shorting wire.
Specifically, as shown in fig. 4, the plurality of third mounting holes 31 are distributed along the circumferential direction of the flange plate 3. A plurality of third mounting holes 31 are used for mounting positive feeder insulators.
In the present embodiment, the number of the first mounting holes 13 is three. The three bolts can stably fix the additional lead shoulder frame in the tunnel on the tunnel lining.
