The invention discloses a lifting rack random locking mechanism of a truss pile leg platform. A rack is arranged on a platform lifting pile; a pawl machine is arranged on the rack of the platform lifting pile; and a pawl shape is arranged at the front end of the pawl machine, and is engaged to the rack. The pawl machine is fixed on a pile area; a pawl pin shaft is arranged at the back end of the pawl machine; a hole is formed in a pin shaft main force board; and the pawl pin shaft penetrates through the hole of the main force plate. The mechanism mainly adopts the hinge type pawl machine, the stressed pile support, the random locking and the force hole control mechanism, and is mounted at the top of the platform pile area; the variable load of the platform vibration is increased or decreased; and the hinge type pawl machine can be firmly buckled on the rack, so that the working gesture tends to an ideal state, and the pile slip phenomenon generated by the platform can be thoroughly prevented. The mechanism needs no auxiliary driving power, is compact in structure, small in volume, convenient to operate and strong in practicability, and can improve the platform operation safety.
