Description

Bending section drive for aerial friction line

Technical Field

Background

The aerial friction line has wide application in automobile factories, can transfer workpieces in a large range, does not occupy the space of ground equipment, and becomes a new generation of mechanized conveying equipment. In the aerial friction line, the running power of the vehicle group comes from a plurality of driving devices arranged beside the line body, the driving devices comprise a friction wheel, an unpowered auxiliary wheel, a driving motor and the like, and the working principle is as follows: the friction wheel is driven by the driving motor to rotate, and when the friction wheel rotates, the conveying trolley moves forwards under the driving of the friction force on the side surface, so that the material conveying is realized.

The driving device has better effect when being used for straight-line segment driving and has certain defect when being used for bent segment driving, and the reason is that: the friction lever promotes the friction pulley and removes toward the track inboard during turn, and the pulling force of spring is not enough to make depended wheel and friction pulley move to the track in step, causes the width that the interval between depended wheel and the friction pulley is greater than the friction lever from this to lead to the friction pulley can't compress tightly platform truck tie rod, this can make the friction pulley skid and can not drive the platform truck and pass through the turn. In view of this, the patent of CN200620073056.0 discloses an improved friction driving device for a curved section of a friction conveying line, which can solve the problem to some extent. In the bending section driving device, a friction wheel and a speed reducer are assembled and then connected with a support, a pinch roller support assembly is connected with a torsion arm mounting support through a torsion arm assembly, the friction wheel assembly is connected with the torsion arm mounting support through a support arm, and a chain tensioning assembly is connected with a spring to realize resetting; the support assembly is provided with a photoelectric switch mounting plate and a reflecting plate mounting frame, and when the photoelectric switch detects the trolley tie bar, the motor is started to drive the friction wheel; the friction wheel frame and the pressing wheel bracket share one rotating shaft, so that the distance between two wheels can be kept unchanged, and the friction wheels, the pressing wheels and the trolley tie rod are compressed by the compression spring; therefore, the trolley tie rod is always in a compressed state when passing through the bending section, the friction wheel cannot slip, and the trolley can quickly pass through the bending section.

However, such a curved friction drive still has major drawbacks. On the one hand, the friction wheel carrier is connected with the pinch roller support into a whole, and the distance between friction wheel and the depended wheel is fixed, leads to above-mentioned curved section friction drive device certain problem can appear: if the width of the friction rod is too small, the friction wheel and the idler wheel cannot simultaneously press the trolley tie rod; if the width of the friction rod is too large, the trolley tie rod cannot pass through the gap between the friction wheel and the idler wheel; when the friction rod is longer and the friction rods of a set of vehicle groups are more, the over-bending can generate great driving deviation at the last friction rod, so that the normal operation of subsequent work is influenced.
