The invention discloses a lifting-type double crossover monorail turnout, and belongs to the technical field of straddle-type monorail transit turnouts. A first track lifting beam and a second track lifting beam which have a certain length and can move up and down are correspondingly arranged on two parallel tracks, a first fixed beam is arranged between the two lifting beams, and a first turnoutlifting beam, a fourth turnout lifting beam, a third turnout lifting beam and a second turnout lifting beam are arranged around the first fixed beam, wherein the first turnout lifting beam and the fourth turnout lifting beam can move up and down and be communicated with track beams at the two ends of the first track lifting beam respectively, and the third turnout lifting beam and the second turnout lifting beam can move up and down and be communicated with track beams at the two ends of the second track lifting beam respectively. According to the lifting-type double crossover monorail turnout, the two parallel tracks are obliquely communicated through corresponding matching and combination of the lifting beams and fixed beams, so that the double crossover of monorail trains is effectivelyachieved, the structure of the double crossover is greatly simplified, the economic cost of the double crossover is reduced, and the application of monorail trains is promoted.

The invention discloses a low-noise anti-eddy current bus bridge which comprises a bus bridge body and a plurality of fixing beams arranged in the bus bridge body. The bus bridge body is made of aluminum-coated zinc plates, and the fixing beams are made of stainless steel. Aiming at the technical problem that a fixed beam of an existing bus bridge is easy to generate heat due to eddy current, the invention provides the low-noise anti-eddy current bus bridge which adopts stainless steel made of a non-magnetic material as the fixed beam, so that the problem of heat generation due to eddy current can be reduced.
