The utility model provides a test device that simulation insulator was trampled belongs to the insulator and detects technical field. The device includes: drive mechanism, wire winding mechanism, drive mechanism and running gear, drive mechanism's moment output with the moment input of wire winding mechanism is connected, wire winding mechanism passes through drive mechanism with running gear connects, wire winding mechanism is used for the basis the torque control of drive mechanism output the running gear predetermined distance of walking. The utility model discloses an experiment can be trampled by more real simulation insulator to torque control running gear that wire winding mechanism the passes through drive mechanism output predetermined distance of walking on composite insulator to composite insulator's atress is more even in the process of the test, and the test result that consequently obtains is more accurate, is fit for trampling experimental standard practices as composite insulator.
