Description

Technical Field

[0001] The utility model relates to monitoring equipment in bulk grain storage, in particular to a hanging rail inspection device. Background Art

[0002] During the storage process of bulk grain, it is necessary to regularly monitor the storage conditions of bulk grain, such as the quantity of bulk grain. Due to the large area of ​​the grain warehouse and the unsuitable indoor temperature environment, manual inspection methods are gradually being replaced.

[0003] The current mainstream inspection mode is to use a hanging rail inspection equipment that can move along the silo roof to inspect the storage conditions of bulk grain. Existing hanging rail inspection equipment, such as the "A track-type bulk grain quantity monitoring device" disclosed in Chinese patent CN220148214U, includes a walking bracket and a track for being set on the top of a silo, and a monitoring unit is provided on the walking bracket, the track includes a transverse track section, a longitudinal track section and an arc track section connected between the transverse track section and the longitudinal track section, the transverse track section, the longitudinal track section and the arc track section all include horizontally arranged wheel plates, and the wheel plates are fixed with left and right anti-deflection plates arranged perpendicular to the wheel plates, and the walking bracket is provided with a left anti-deflection wheel that is in rolling contact with the right side plate surface of the left anti-deflection plate and a right anti-deflection wheel that is in rolling contact with the left side plate surface of the right anti-deflection plate, and the walking bracket is also provided with a left walking wheel and a right walking wheel, the left walking wheel is in rolling contact with the wheel plate on the left side of the left anti-deflection plate, and the right walking wheel is in rolling contact with the wheel plate on the right side of the right anti-deflection plate, and the walking bracket is provided with a walking wheel driving mechanism that drives the left and right walking wheels to rotate.

[0004] During operation, the wheel drive mechanism drives the traveling frame along the track, and the monitoring unit on the traveling frame monitors the bulk grain in the granary. Existing rail inspection equipment for this type of hanging rail is plagued by problems: although anti-skew wheels and anti-skew plates are used to adapt to the curves of the track, the wheels are unable to turn, resulting in very limited steering capabilities and significant wear on the wheels during hard turns. Furthermore, the anti-skew wheel structure is complex, resulting in a large and uncompact device. Utility Model Content

The bottom of each follower wheel and driving wheel is designed to roll-fit with the corresponding track base plate. The running wheel drive mechanism is installed on the running bracket and is in driving connection with the first and second driving wheels. The rotation axes of the follower and driving wheels are arranged horizontally, and the intermediate track beam is located between the two driving wheels and the two follower wheels.
