Spraying-pipe testing device

The invention discloses a spraying-pipe testing device, and belongs to the technical field of rocker engine testing. The spraying-pipe testing device aims at guaranteeing that a swing type spraying pipe is fixed. According to the technical scheme, the spraying-pipe testing device is mainly composed of a support, adjustment plates and a clamp; the support is mainly formed by stand columns, a transverse beam, bases and reinforcing ribs in a welded mode. Each adjustment plate is composed of a U-shaped plate, a slab, a bolt, a fixed nut and an adjustment nut. The clamp mainly comprises a clamping ring, connecting lugs and idler wheels, and a buffering layer is arranged at the inner ring of the clamping ring. When the spraying-pipe testing device is used, the clamping ring is installed on the swing type spraying pipe, then the assembly is installed in the support, the adjustment nut is adjusted, and the center of the swing type spraying pipe can be guaranteed accordingly. The spraying-pipe testing device has the advantages of being simple in structure, good in effect and capable of being applied to fixing multiple swing type spraying pipes.
