Background

With the continuous improvement of the technology level, more intelligent and convenient warehousing systems and warehouses become a new trend for managing warehouses of large-scale factories and logistics companies. Traditional warehouse mainly relies on manual management, and warehouse management personnel need know the vacant position of goods shelves constantly to deposit the new goods of putting in storage, still need to know the accurate position of each goods simultaneously, so that can in time seek out when drawing the goods. When warehouse goods are more, and when the warehouse entry is frequent, can consume very big human cost, and be difficult to guarantee the efficiency of the warehouse entry and warehouse exit of goods, consequently wait to improve, current intelligent warehouse generally adopts tunnel stacker mechanism to transport in addition, and tunnel stacker is that it is evolved by fork truck, bridge type stacker to belong to intelligent warehouse. The bridge type stacker is limited in operation speed due to the heavy bridge frame, and is only suitable for warehouses with low warehousing and ex-warehouse frequency or warehouses for storing long raw materials and heavy goods.

when the fork telescopic mechanism 3 needs to be adjusted during the transportation of goods, a worker manually starts the controller, the controller controls the first motor reducer 31 to start working, the first motor reducer 31 rotates to drive the chain wheel 32 to rotate, the chain wheel 32 rotates to drive the torque limiter 34 to rotate, the torque limiter 34 rotates to drive the driving shaft 35 to rotate, the driving shaft 35 rotates to drive the driving gear 36 to rotate, the driving gear 36 rotates to drive the driven gear 37 to rotate, the driven gear 37 rotates to drive the rack 38 to rotate, meanwhile, the driven gear 37 rotates to drive the first fork 311 to extend and retract from the front and back of the midpoint of the fixed fork 39 through the first guide wheel group 310, the rack 38 rotates to drive the second fork 312 to extend and retract from the front and back of the midpoint of the first fork 311 through the second guide wheel group 313, when the specified position is reached, the first approach switch senses a signal and sends the signal to the controller, the controller controls the first motor reducer 31 to stop working so as to facilitate subsequent operation of workers;

when the lifting height needs to be adjusted during cargo handling, a worker manually starts the controller, the controller controls the second motor reducer 41 to start working, the output shaft of the second motor reducer 41 rotates to drive the winding drum 42 to rotate, the winding drum 42 rotates to drive the first steel wire rope 43 to stretch, the first steel wire rope 43 stretches to drive the movable pulley 231 to lift, the movable pulley 231 lifts to drive the cargo carrying table 2 to lift, when the specified position is reached, the third proximity switch senses a signal and sends the signal to the controller, and the controller controls the second motor reducer 41 to stop working, so that the worker can perform subsequent operation;

when the load borne on the cargo carrying platform 2 exceeds the maximum allowable value, when the tension of the first steel wire rope 43 is large, the spring dynamometer of the overload rope loosening protection unit 45 detects that the tension of the extension spring is too large, the spring dynamometer transmits a signal to the controller, and the controller sends a signal to return a power supply or a main power supply of the second motor reducer 41, so that the second motor reducer 41 stops working, and the hoisting mechanism 4 is ensured to stop running in time;

when the cargo carrying platform 2 is caused to descend in an overspeed manner due to some reason (such as the breakage of a steel wire rope or a chain, the breakage of a hoisting motor or a speed reducer, and the like), when the speed limited by the overspeed protection mechanism 8 is reached, when the cargo carrying platform 2 drops at an overspeed due to some reason in the lifting process of the cargo carrying platform 2, the speed limiter 81 is driven to move at an overspeed through the steel wire rope 83, so that the rope wheel on the speed limiter 81 rotates in an overspeed way, when the speed reaches a preset speed, the pawl of the speed limiter 81 automatically blocks the ratchet wheel of the speed limiter 81, at the moment, the rope wheel of the speed limiter 81 stops rotating, the second travel switch detects that the rope wheel of the speed limiter 81 stops rotating and sends a signal to the controller, the controller sends a signal to cut off the main power supply of the intelligent warehouse, the second steel wire rope 83 is acted by a balance block of the speed limiter 81, so that an eccentric wheel of the brake clamping structure 82 is forced to rotate, and the brake clamping structure 82 is firmly clamped on a brake reporting guide rail of the upright 12;

when actually transporting goods, the staff moves the device to the goods position, and manually start the controller, the control panel through the operation controller adjusts the horizontal distance and the lifting height from the goods (see the above for details of specific operation), so as to transport the goods, then the staff operates the control panel of the controller to adjust the fork telescopic length of the fork telescopic mechanism 3 (see the above for details of specific operation), so as to be suitable for the size of the goods, and after the fork telescopic mechanism 3 transports the goods, the staff can operate the control panel of the controller to transport the goods to the specified position.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
