Device for locking a belt at predetermined belt tension

A device for locking at least one belt (10) at predetermined belt tension, the at least one belt (10) being arranged at a machine arrangement (1) having a belt drive, the machine arrangement (1) comprising a stand (3) having legs (2) placed on a base (4), at least one driving pulley (5) which is arranged on a drive shaft (5b), and at least one driven pulley (6), the at least one driving pulley (5) and the at least one driven pulley (6) being aligned relative to each other, the legs (2) being articulately attached to at least one of the stand (3) or the base (4), wherein at least two of the legs (2) comprise longitudinally adjustable tension legs (20), each of the longitudinally adjustable tension legs (20) comprising a first tension leg part (21) and a second tension leg part (22);

• the first tension leg part (21) having a wedge box (30) arranged to receive a wedge (31);
• the wedge (31) having a grooved surface (32) and the second tension leg part (22) having a grooved surface (23) directed towards the grooved surface (32) of the wedge box (30), such that the first (21) and second (22) tension leg parts are adapted to lock in relation to each other by cooperation between the grooved surface (32) of the wedge (31) and the grooved surface (23) of the second tension leg part (22) when the wedge (31) is wedged in the wedge box (30).
