The invention discloses a banana-type bridge construction safety ladder and relates to a safety ladder. The banana-type bridge construction safety ladder comprises adjustable bases, vertical rods, transverse rods, pin cartridges, diagonal rods, and banana head cross braces. The vertical rods are arranged around the adjustable bases. The pin cartridges are disposed on the vertical rods. Both the transverse rods and the banana head cross braces are disposed between the vertical rods through the pin cartridges. The diagonal rods are diagonally disposed on the pin cartridges at the opposite corners of each two adjacent levels of the vertical rods. A ladder is arranged between each two banana head cross braces at different heights. Each ladder is provided with platform access steps. The banana-type bridge construction safety ladder is composed of a banana scaffold and a special zigzag ladder, has multiple functions, and is high in bearing capacity, safe and reliable, simple and convenient to mount, and highly practicable.

The embodiment of the invention discloses a transmission shaft of the double shunting reducer, which comprises a ring groove arranged on the transmission shaft, a radial hole arranged in the ring groove and an axial hole communicated with the radial hole. A gear positioned on the transmission shaft of the double shunting reducer provided by the embodiment of the invention is fixed on the position where the ring groove is located by interference fit; high-pressure oil enters into the radial hole through the axial hole and then flows into the ring groove; after the ring groove is filled with the high-pressure oil, the gear is isolated from the transmission shaft under the action of oil pressure, the transmission shaft is adjusted to be in a synchromesh position with the other gear; after the adjustment, the injection of the high-pressure oil stops so as to recovery the interference fit of the gear and the transmission shaft. The embodiment of the invention solves the problem that the gears on two transmission shafts at the same level are not synchronously meshed with the gears at the adjacent level. The embodiment of the invention also discloses a double shunting reducer with the above transmission shaft.
