The invention discloses a drilling machine derrick trailer frame. The frame structure is divided into three layers of an upper layer, a middle layer and a lower layer, and comprises a main frame, limiting beams and lifting beams which are sequentially arranged from bottom to top, wherein the main frame is formed by welding two longitudinal beams and a plurality of cross beams, a traction mechanismis arranged at the front end of the main frame, the two limiting beams are perpendicular to the main frame and are fixed on the longitudinal beams of the main frame in parallel, the two lifting beamsare symmetrically fixed on the two limiting beams and are located in the same plane as the corresponding limiting beams, each of the two ends of the connected limiting beam and lifting beam of each group is in hinged connection through a lifting oil cylinders, the two lifting beams are fixedly connected through a pull rod, four hydraulic supporting leg mounting supports and two axle mounting supports are symmetrically arranged on the two longitudinal beams of the main frame, and four drilling machine derrick fixing assemblies are symmetrically arranged on the two lifting beams. The trailer frame is convenient to disassemble and assemble and convenient to transport, and the transportation cost can be effectively saved.
