Description

Lifting machine transfer system suitable for floor track

Technical Field

The invention relates to the technical field of lifting equipment, in particular to a transfer system of a lifting machine, which is suitable for a ground paving track.

Background

In an automatic stereoscopic warehouse, in order to save the occupied space under the condition of compact space of the automatic stereoscopic warehouse and reduce the logistics cost under the condition of eccentric budget, a vehicle carrying hoister can be arranged at the end of a goods shelf in the automatic stereoscopic warehouse so as to realize the transfer and layer changing of the shuttle vehicle between different layers of the goods shelf, reduce the matching number of shuttle vehicle equipment and reduce the fault rate, and the layer changing efficiency of the shuttle vehicle is better improved while the throughput of a system is not influenced, thereby meeting the overall performance requirement of the system. Most of the existing car-carrying hoists comprise a hoist frame and a goods-carrying platform, and a photoelectric protection device is arranged on the hoist frame to detect and protect the four-way cars on the goods-carrying platform, so that the four-way cars are prevented from falling off from the hoist under the condition that the four-way cars are subjected to layer changing or connection.

The existing vehicle-mounted elevator usually only adopts a photoelectric protection device to protect a four-way vehicle, but under the condition that the four-way vehicle changes layers in the elevator, if the photoelectric protection device breaks down, the four-way vehicle cannot be continuously protected, or under the condition that the four-way vehicle does not carry out scheduling operation according to instructions, the four-way vehicle easily falls off from a cargo carrying platform, and the four-way vehicle is undoubtedly damaged by being difficult to recover. In addition, the bottom end of a loading platform of the existing vehicle-carrying hoister has a certain height from the ground, and a cross beam is arranged in front of a frame of the hoister for blocking, so that the loading platform cannot be connected with a floor track under the condition of delivery, and a four-way vehicle on the loading platform cannot carry goods to move onto the floor track, thereby undoubtedly reducing the delivery efficiency and lowering the practicability of the floor track; and if the vehicle-carrying hoister is installed in the ground groove, the labor intensity of workers is increased undoubtedly, and the groove needs to be filled up by the workers after the vehicle-carrying hoister moves away, so that under the condition that the vehicle-carrying hoister is connected with the floor track in a short period, the labor intensity of the workers is increased and the ground of the warehouse is easily damaged by installing the vehicle-carrying hoister in the ground groove.

At present, no effective solution is provided for the problems that the prior vehicle carrying hoister cannot intercept and protect a four-way vehicle under the condition that a photoelectric protection device fails, the four-way vehicle on the prior vehicle carrying hoister cannot directly move to a ground track or the vehicle carrying hoister mounted on a ground groove is easy to damage the ground of a warehouse.

In some of these embodiments, the second supporting member 750 further includes a plurality of rollers provided on the lower inclined surface of the supporting plate 752 for facilitating the supporting plate 752 to enter the inside of the corresponding second mounting groove member 740 in the case that the flooring rail 800 presses the inclined surface of the supporting plate 752.

The working principle of the invention is as follows:

under the condition that the cargo bed unit 300 moves downward in the frame unit 100, the driving motor 321 drives the driving gear 323 to rotate, the driving motor 321 drives itself to move downward through the transmission rack 221, and then the driving motor 321 drives the second frame element 310 to move downward through the bearing piece 322;

in the process of moving the second frame element 310 downward, if the shifting block element 350 mounted on the second frame element 310 abuts against the adjusting element 510, the shifting block element 350 presses the adjusting element 510 to turn downward, the adjusting element 510 drives the first transmission gear 523 to rotate, the first transmission gear 523 drives the second transmission gear 533 to rotate, the second transmission gear 533 drives the baffle element 540 to turn over so as not to block the four-way vehicle from moving, until the top end of the baffle element 540 turns over to the lower side corresponding to the top end of the first cross beam after the second frame element 310 moves downward to a certain distance, so that the four-way vehicle can exit the second frame element 210 through the guide rail element 140 to enter the transfer element 720 or the shelves at different levels;

under the condition that the second frame member 310 moves downward to the bottom end of the frame unit 100 and the four-way vehicle travels onto the transfer member 720, the driving motor 321 drives the second frame member 310 to move downward continuously, so that the pressing block member 360 presses the driven plate 632 to move downward, the driven plate 632 drives the driven rack 631 to move downward, the driven rack 631 drives the first driven gear 652 to rotate, the first driven gear 652 drives the rotating shaft 651 to rotate, the rotating shaft 651 drives the driven shaft 661 to rotate, the driven shaft 661 drives the two second driven gears 662 to rotate, the two second driven gears 662 drive the four second rack members 760 to move downward, and then the second rack member 760 drives the transfer member 720 to move downward, so that the floor rail 800 presses the supporting plate 752, so that the supporting plate 752 enters the second mounting groove member 740, so that the four-way vehicle falls onto the floor rail 800, and then after the four-way vehicle travels away, the driving motor 321 drives the second frame member 310 to move upward, so that the pressing block member 360 does not press the driven plate 632 any more;

finally transfer element 720 is moved upwards by second return spring 751 and by second return element 620 to continue to pick up the next four-way vehicle.

All possible combinations of the technical features in the above embodiments may not be described for the sake of brevity, but should be considered as being within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.
