Furthermore, the auxiliary suspension post mechanism comprises a suspension post, a bottom plate and rib plates, the bottom plate is fixed at two ends of the suspension post respectively, the rib plates are fixedly connected with the suspension post and the bottom plate respectively, and the bottom plate at the lower end of the suspension post is connected with the horizontal section of the L-shaped suspension bracket through a U-shaped bolt.
Furthermore, the rib plate is provided with a small hole, and the small hole is used for connecting a grounding jumper.
Further, the reserved bottom plate and the bottom plate are both provided with bolt holes and connected through bolts.
Furthermore, the number of the auxiliary suspension post mechanisms is more than one.
Compared with the prior art, the utility model discloses the beneficial effect who has is:
1. the utility model discloses a L type gallows is connected with a plurality of reservation bottom plates that set up on the ball joint respectively, and a plurality of circuit station tracks are spaned to the horizontal segment of L type gallows, for contact net suspension device provides the mounted position, and contact net suspension device can all be installed to the optional position of horizontal segment, does not have the contact net directly over the specially adapted circuit and suspends the condition of some in midair.
2. The utility model discloses a L type gallows, its vertical section passes through the bottom plate to be fixed on reserving the bottom plate, the horizontal segment passes through supplementary davit mechanism to be fixed on reserving the bottom plate, horizontal segment and supplementary davit mechanism pass through U type bolted connection, L type gallows is compared with U type gallows (the both ends of U type gallows all need fix on reserving the bottom plate), its horizontal segment can remove about supplementary davit mechanism, be convenient for finely tune when the installation, prevent to appear leading to the bolt hole not to the top because of the error problem, the condition on reserving the bottom plate can't be installed, the adjustability and the precision of installation have been increased. Simultaneously, the L type structural style of gallows has also improved gallows intensity when having reduced welding point and process.
