Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to a double-motor three-deep position cargo fork. Background Art

[0002] In the current market, telescopic forks, as key equipment in the field of warehousing and logistics, are becoming increasingly diversified in types and application scenarios. The current mainstream product types mainly include single-depth forks and double-depth forks. The lateral coverage capacity of these forks is generally limited to two storage locations; however, with the continuous advancement of modern warehousing technology and the increasingly significant trend of intensive storage, the market's requirements for fork performance are also constantly increasing, and the demand for lateral coverage of three storage locations has gradually surfaced. Such a demand obviously makes traditional single-depth and double-depth forks seem incapable of meeting the higher requirements of modern warehousing.

[0003] The existing three-deep forklift is a single motor structure, which includes a fixed fork body and four telescopic fork bodies. When the forklift is working, the four telescopic forks are extended and retracted at the same time. When taking goods from the three-deep position, the pallet on the three-deep position needs to meet the height of the two fork bodies above; when taking goods from the double-deep position and single-deep position, the pallet on the double-deep position and single-deep position needs to meet the height of the four telescopic forks. Therefore, the storage capacity of double-deep and single-deep shelves is relatively limited. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a dual-motor three-deep fork, which can meet the three-position picking demand, improve warehouse utilization and increase inventory capacity.

[0005] The technical solution adopted by the utility model is as follows: a dual-motor three-depth cargo fork, which comprises, from top to bottom, an upper fork assembly, a middle-upper fork assembly, a middle fork assembly, a middle-lower fork assembly and a lower fork assembly; the upper fork assembly is sleeved on the middle-upper fork assembly, the middle-upper fork assembly is sleeved on the middle fork assembly, the middle fork assembly is sleeved on the middle-lower fork assembly, the middle-lower fork assembly is sleeved on the lower fork assembly, and the lower fork assembly is connected to a driving unit; the structure of the driving unit is as follows: comprising a single-double-depth motor and a triple-depth motor; the single-double-depth motor controls the linkage between the upper fork assembly, the middle-upper fork assembly and the middle fork assembly; the triple-depth motor controls the linkage between the upper fork assembly, the middle-upper fork assembly, the middle fork assembly and the middle-lower fork assembly.

[0006] As a further improvement of the above technical solution:

[0007] Preferably, the single-double-depth motor and the triple-depth motor are both connected to a torque limiter, a transmission roller chain is sleeved on the torque limiter, and a sprocket is matched at the other end of the transmission roller chain.

[0008] Preferably, the single-double-depth motor transmits torque to the single-double-depth motor gearbox through a torque limiter, a transmission roller chain and a sprocket; the single-double-depth motor gearbox transmits power to the lower fork gearbox chain gear through a connecting gear, the lower fork gearbox chain gear engages with the middle and lower fork roller chain, the middle and lower fork roller chain engages with the middle fork chain rack, the middle fork assembly extends, the middle and upper fork assembly extends through the first plate chain under the drive of the middle fork assembly, and the upper fork assembly extends through the second plate chain under the drive of the middle and upper fork assembly.

[0009] Preferably, the three-deep motor transmits torque to the three-deep motor gearbox through a torque limiter, a transmission roller chain and a sprocket, and the three-deep motor gearbox transmits power to the lower fork gearbox transmission gear through a connecting gear, the lower fork gearbox transmission gear meshes with the middle-lower fork rack, the middle-lower fork assembly extends, the middle fork chain rack meshes with the middle-lower fork roller chain, the lower fork gearbox chain gear locks, the middle fork assembly is driven by the engagement of the middle fork chain rack and the middle-lower fork roller chain and extends under the drive of the middle-lower fork assembly, the middle-upper fork assembly extends through the first plate chain under the drive of the middle fork assembly, and the upper fork assembly extends through the second plate chain under the drive of the middle-upper fork assembly.

[0010] Preferably, the single double-deep motor and the triple-deep motor are located below the lower fork assembly and arranged front to back.

[0011] The beneficial effects of the utility model are as follows:

[0012] The utility model has a compact structure and is easy to operate. The three-deep motor setting can meet the picking needs of three storage locations. Through the single-double-deep motor setting, when picking up goods from a double-deep location, the single-double-deep motor controls the linkage of the upper fork, the middle upper fork and the middle fork, that is, the middle and lower fork does not move, and the height of the pallet at the double-deep location only needs to meet the thickness of the upper fork and the middle upper fork; when picking up goods from a single-deep location, the single-double-deep motor controls the linkage of the upper fork, the middle upper fork and the middle fork, that is, the middle and lower fork does not move, and the height of the pallet at the single-deep location only needs to meet the thickness of the upper fork, the middle upper fork and the middle fork;

[0013] The utility model can select a triple-deep motor or a single-double-deep motor to work when in use, thereby improving the utilization rate and storage capacity of the warehouse; further, it can save considerable investment for customers. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In this embodiment, illustratively, the single double-deep motor 601 and the triple-deep motor 602 are placed below the lower fork assembly 5 and arranged front to back.

[0024] In actual work, the working method of the utility model is as follows:

[0025] When the single-double-depth motor 601 is working, the torque is transmitted to the single-double-depth motor gearbox 606 through the torque limiter 603, the transmission roller chain 604 and the sprocket 605; the single-double-depth motor gearbox 606 transmits the power to the lower fork gearbox chain gear 610 through the connecting gear, the lower fork gearbox chain gear 610 is meshed with the middle and lower fork roller chain 611, the middle and lower fork roller chain 611 is meshed with the middle fork chain rack 614, the middle fork assembly 3 is extended, the middle and upper fork assembly 2 is extended through the first plate chain 612 under the drive of the middle fork assembly 3, and the upper fork assembly 1 is extended through the second plate chain 613 under the drive of the middle and upper fork assembly 2.
