Disclosure of Invention
The invention aims to provide an overturn preventing method and an overturn preventing device for emergency braking of an intermediate storage movable cart, which can better prevent the overturn of the cart during emergency braking, have simple structure and are easy to reform the existing intermediate storage movable cart.
The invention is realized by the following technical scheme:
the overturn preventing method for emergency braking of movable intermediate storage cart includes the following steps: when the middle storage mobile cart is in the process of traveling and the driving wheel is positioned at the front side position of the driven wheel, if the driving wheel brakes suddenly and the speed drops to zero suddenly, under the action of inertia, the body of the intermediate storage mobile cart tilts forward around the driving wheel, the driven wheel lifts off the ground, at the moment, the supporting piece positioned on the front side of the driving wheel passively moves downward along with the forward tilting of the intermediate storage mobile cart, or the supporting piece is driven by the power of linkage control to actively move downwards to abut against the ground or abut against a limiting piece matched with the supporting piece on the ground, therefore, an anti-tilting moment is formed on the front side of the driving wheel of the middle storage mobile cart to prevent the middle storage mobile cart from further tilting forwards until the middle storage mobile cart returns to a normal parking position under the action of the combined force of the anti-tilting moment and the dead weight, the supporting piece is lifted off the ground or leaves a limiting piece matched with the supporting piece on the ground, and the middle storage mobile cart can continue to normally advance.
Furthermore, the supporting piece is a hydraulic jacking mechanism, a supporting frame or a supporting plate. The hydraulic jacking mechanism is in linkage control with the driving wheel, and when the driving wheel is braked suddenly, the hydraulic jacking mechanism jacks towards the ground until the hydraulic jacking mechanism abuts against the ground or a matched limiting part on the ground, so that effective support for the middle storage mobile cart is formed; the lower end of the supporting frame/supporting plate is tightly abutted against the ground or a matched limiting piece on the ground when the middle storage mobile cart tilts forwards, so that effective support for the middle storage mobile cart is formed; the supporting modes belong to fixed supporting, in practical application, although the middle storage mobile cart can be prevented from further overturning, the load of the supporting piece is large, and meanwhile, the middle storage mobile cart is likely to be stressed in a balanced supporting position and cannot be timely returned to a normal parking position.
The intermediate storage mobile cart can thus be supported in a mobile manner by means of support wheels, which are axially rotatable about its own axis and whose axle is parallel to the axle of the drive wheels. When the middle storage mobile cart tilts forward, the supporting wheels touch the ground and are forced to rotate under the forward tilting inertia of the middle storage mobile cart, meanwhile, an anti-tilting moment is formed on the front side of the driving wheel of the middle storage mobile cart to prevent the middle storage mobile cart from further tilting forward, the middle storage mobile cart continues to decelerate forward and rapidly decreases the overturning moment generated by inertia, the middle storage mobile cart returns to a normal parking position under the combined action of the anti-tilting moment and the dead weight, and the supporting wheels lift off the ground. The movable supporting mode not only has small load of the supporting wheels, but also can ensure that the middle storage movable cart can return timely and effectively.
Furthermore, the travel distance between the supporting piece and the ground, or the travel distance between the supporting piece and the limiting piece matched with the supporting piece on the ground can be adjusted, so that the installation height of the supporting piece can be flexibly adjusted according to the ground condition of a specific warehouse, a proper travel position is selected, and the supporting effect is ensured.
An anti-overturning device applying the anti-overturning method for emergency braking of the intermediate storage mobile cart is characterized in that:
a row of wheels are respectively arranged on a chassis of the middle storage mobile cart at the front side and the rear side of the traveling direction of the middle storage mobile cart, wherein one row is a driving wheel, and the other row is a driven wheel; the driving wheel can rotate forward and backward under the driving of power, so that the intermediate storage mobile cart is driven to move forward;

The structure is convenient for arranging the supporting wheels and the anti-tilting frame, the fixing of the anti-tilting frame can not occupy the stacking position of the cart, and meanwhile, the satellite trolley can not interfere with the anti-tilting frame when moving the artificial board.
Still further, the diameter of the supporting wheel is smaller than the radius of the driving wheel, and the wheel axle of the supporting wheel is positioned below the wheel axle of the driving wheel. The small supporting wheels not only occupy small space and are convenient to arrange, but also have stable anti-tilting structure.
