Abstract
A cargo handling system is disclosed herein. The cargo handling system includes a ball panel for moving and storing cargo and a cargo restraining device disposed within the ball panel. The cargo restraining device includes a first side plate, a motor coupled to the first side plate, an outer pawl, an inner pawl configured to engage the outer pawl, and a belt drive assembly coupled to the motor and to the inner pawl, the belt drive assembly configured to engage the inner pawl to extend and retract the inner pawl.
Claims17
A cargo handling system, comprising:
- a ball panel for moving and storing cargo;
- and
- a cargo restraining device disposed within the ball panel, the cargo restraining device including:
- a first side plate;
- a motor coupled to the first side plate;
- an outer pawl;
- an inner pawl configured to engage the outer pawl;
- and
- a timing belt drive assembly coupled to the motor and to the inner pawl, the timing belt drive assembly configured to engage the inner pawl to extend and retract the inner pawl, wherein the timing belt drive assembly comprises:
- a first timing belt pulley coupled to the motor;
- a second timing belt pulley;
- an intermediate pulley shaft;
- a split pulley shaft coupled to the inner pawl;
- a first timing belt coupled to the first timing belt pulley and the intermediate pulley shaft;
- a second timing belt coupled to the intermediate pulley shaft and the second timing belt pulley;
- and
- a third timing belt coupled to the second timing belt pulley and the split pulley shaft.
A cargo restraining device, comprising:
- a first side plate;
- a motor coupled to the first side plate;
- an outer pawl;
- an inner pawl configured to engage the outer pawl;
- a belt drive assembly coupled to the motor and to the inner pawl, the belt drive assembly configured to engage the inner pawl to extend and retract the inner pawl;
- a first timing belt pulley coupled to the motor;
- a second timing belt pulley;
- an intermediate pulley shaft;
- a split pulley shaft coupled to the inner pawl;
- a first timing belt coupled to the first timing belt pulley and the intermediate pulley shaft;
- a second timing belt coupled to the intermediate pulley shaft and the second timing belt pulley;
- and
- a third timing belt coupled to the second timing belt pulley and the split pulley shaft.
A system, comprising:
- a motor;
- a timing belt drive assembly coupled to the motor;
- a first pawl;
- a second pawl coupled to the timing belt drive assembly, the second pawl engaging the first pawl causing the first pawl to extend in response to the second pawl extending;
- a processor;
- and
- a speed controller in communication with the processor;
- and
- a memory operatively coupled to the processor, the memory comprising instructions stored thereon that, when executed by the processor, cause the processor to:
- send a first instruction to the speed controller, wherein, responsive to receiving the first instruction, the speed controller is configured to:
- send a first current to the motor to rotate in a first direction to extend the second pawl;
- and
- responsive to the motor rotating a first number of rotations, stop the first current to the motor thereby locking the first pawl and the second pawl in an extended position.
