Wing type trestle
The invention discloses a wing type trestle which comprises a jumping wharf. The jumping wharf is provided with a floating wharf and a deck. Fixing bridges and telescopic bridges are arranged on the two sides of the floating wharf. One end of each fixing bridge is hinged to the floating wharf. The other end of each fixing bridge is provided with a fixed pulley. Each telescopic bridge is arranged in the corresponding fixing bridge in a sliding mode. Gear and rack mechanisms are arranged between the fixing bridges and the telescopic bridges. A support is fixedly arranged on the deck. Two groups of motors and speed reducers are fixedly arranged on the support. Motor main shafts and input shafts of the speed reducers are connected. Output shafts of the speed reducers are connected with coiling blocks. The two ends of the support are provided with a plurality of fixed pulleys corresponding to the fixing bridges at the corresponding ends respectively. Two steel wire ropes are wound on the coiling blocks in the corresponding group and the fixed pulleys respectively. The bank connecting distance and angles can be adjusted conveniently and smoothly, so that the wing type trestle is suitable for water level changing, the bank connecting requirement is met at any time, operation is convenient, labor intensity is low, and safety is good.
