Combined hydraulic testing frame adopting multi-section trusses

The utility model discloses a combined hydraulic testing frame multi-section trusses, which comprises a front truss (4), a tail truss (2) and more than one middle truss (3), wherein the trusses are connected and combined into the hydraulic testing frame with the length required by a user through bolts (1); and a tail seat (5) and a push-pull seat (6) are arranged on the hydraulic testing frame, the push-pull seat (6) is connected with a piston rod of a hydraulic cylinder (7), and clamping grooves (11) for clamping testing joints are formed on the tail seat (5) and the push-pull seat (6). The combined hydraulic testing frame adopting multi-section trusses divides the hydraulic testing frame with very long length and very heavy weight into multi-section trusses for manufacturing, and the trusses are connected by the bolts (1), so that the transportation, the hoisting and the mounting are facilitated, and labor intensity of workers is reduced. A user can detect the maximum length of an oil tool, and purchase or
