The flat carrier roller group is arranged on a clamping groove on the belt storage bin frame and is mainly used for supporting a lower belt to ensure the requirement of the belt conveyor on the sag of the belt. The wheels of the traveling trolley are embedded into the groove-shaped rails through an embedded structure, so that the jumping, the deviation and the torsional pendulum of the wheels are limited, the phenomenon of derailing and derailing of the trolley can be avoided, and the normal operation of the belt conveyor is ensured.

The whole structure of the bin frame and the original bin frame can be interchanged and used universally; a groove-shaped track is embedded on the side frame of the storage belt bin rack, the groove-shaped track is supported by multiple points to ensure the rigidity and straightness of the track, and the whole structure is compact; wheels of the traveling trolley are embedded into the groove-shaped track to travel; the wheels and the channel steel guide rail form a transverse self-aligning conjugate tread, so that the traveling trolley can be ensured not to deviate and derail during running. The half taper of the wheel is consistent with the inclination of the tread of the inner opening of the channel steel track to form an inclined line contact pair, and the transverse friction automatic centering can be realized by double-wheel operation; meanwhile, the small gap between the groove-shaped track and the embedded wheel forms vertical self-limiting, the left and right self-limiting can be realized through the wheel rim interval and the small gap between the channel steel track inner side interval on the bin frame, the trolley wheels can only walk forwards and backwards in the track, the overall structure strength and the rigidity are high, and the trolley is not easy to deform.

The utility model discloses a dolly that moves about realizes the storage area and the tensioning of crossheading belt feeder in the storehouse frame back-and-forth movement, is applicable to colliery crossheading haulage roadway in the pit, accomplishes coal transportation task jointly. Aiming at the phenomenon of trolley falling during the operation process of the conventional crossheading telescopic belt conveyor, the wheels of the traveling trolley are embedded into the grooved rails, and small gaps between the wheels and the grooved rails limit the jumping, deviation and torsion of the wheels, so that the phenomenon of trolley falling from the rail due to derailment is avoided, the trolley is prevented from derailing, and the safe operation of the belt conveyor is ensured.
