An anti-overturning method and anti-overturning device for an intermediate storage mobile cart during sudden braking

Abstract

The invention provides an anti-overturning method and an anti-overturning device for the emergency brake of a middle store mobile cart. When the middle store mobile cart is in a advanced process, and driving wheels are located in the front side position of driven wheels, if the driving wheels are urgently braked, and the speed is reduced to the zero, under the action of inertia, the body of the middle store mobile cart is leaned forward around the driving wheels, and the driven wheels are departed from the ground; this moment, support pieces located on the front side of the driving wheels move down along the forward leaning of the middle store mobile cart, and close to the ground, so that an anti-careen moment is formed in the front side of the driving wheels of the middle store mobile cart, the further forward leaning of the middle store mobile cart is prevented, and until the middle store mobile cart is returned to the normal parking position under the resultant action of the anti-careen moment and the self weight. According to the anti-overturning method and the anti-overturning device for the emergency brake of the middle store mobile cart, a problem that the middle store mobile cart is leaned forward when the driving wheel is urgently braked can be greatly solved, so that the advancing of the middle store mobile cart can be more reliable and safe; and the anti-overturning method and the anti-overturning device for the emergency brake of the middle store mobile cart can be reconstructed based on the existing middle store mobile cart structure, the reconstructed cost is low, and promotion is facilitated.

Description

technical field [0001] The invention relates to the field of storage and transfer of man-made panels, in particular to an intermediate storage mobile cart. Background technique [0002] Intermediate storage mobile carts are usually used in conjunction with satellite trolleys, lifting mechanisms, automatic control systems and warehouse management systems (WMS). It can realize functions such as automatic positioning, automatic stockpiling, automatic picking up, and cargo search and retrieval. [0003] The intermediate storage mobile cart moves back and forth along the track groove on the central axis of the warehouse through the drive of the bottom wheel, so as to realize its entry and exit at different depth positions in the warehouse; the movement direction of the intermediate storage mobile cart is perpendicular to the length direction of its chassis, that is, the mobile cart The car is placed horizontally on the track groove: the artificial boards are stacked along the le...

AI Technical Summary

Problems solved by technology

During actual operation, if the driving wheel is located at the front side of the traveling direction of the intermediate storage mobile cart, during the load movement process of the intermediate storage mobile cart, if the driving motor of the driving wheel stops due to power failure or other reasons, the drive motor and the drive The reducer between the wheels will automatically brake, causing the driving wheel on the front side to stop in an emergency brake, and the speed will drop to zero, while the driven wheel on the rear side will continue to move forward under the action of inertia, causing the cart to drive around. The forward tilt of the wheels is very likely to cause the overall overturning of the vehicle body, damage the intermediate storage mobile cart and the man-made panels of the load, and more seriously, pose a threat to the personal safety of the operators on the intermediate storage mobile cart
