This invention relates to the field of belt conveyors and discloses a tensioning device for a long-distance belt conveyor, comprising a tensioning trolley and a tower counterweight device. The tensioning device includes a braking drum mechanism disposed between the tensioning trolley and the tower counterweight device. The braking drum mechanism includes a support bracket fixed to the ground, a drum for winding multiple turns of steel wire rope, and a braking mechanism for braking the drum. The support bracket has two suspended extension ends, the drum is rotatably disposed between the two suspended extension ends, and the braking mechanism is disposed at one end of the drum's axial direction. This tensioning device, by adding a braking drum mechanism between the tensioning trolley and the tower counterweight device, brakes the steel wire rope when encountering instantaneous changes in tension, thus fixing the steel wire rope and preventing the tower counterweight device from overshooting or crashing to the ground.
