Description

Technical Field

[0001] The invention relates to the technical field of transfer devices, in particular to a cross-arm lifting fork-type transfer module. Background Art

[0002] At present, the transfer of shells in the ammunition depot is achieved through a hydraulic transfer machine. The hydraulic pump drives the hydraulic motor to start the transfer machine. The transfer machine realizes horizontal and vertical movement through the gear and rack transmission chain. The transfer machine moves horizontally to a specific position and stops. The shells are manually lifted and placed on the elevator through chain transmission. The elevator lifts the shells to the deck through the power of the hydraulic cylinder, thereby realizing the storage and retrieval of shells. During the use of the hydraulic transfer module, the transfer action and the lifting action need to be performed in stages, resulting in low efficiency and slow response speed in the storage and retrieval of shells. The process of transferring shells in the ammunition depot requires manual cooperation and has not been automated. This has reduced the efficiency of the troops' transfer of shells to a certain extent and cannot meet the needs of unmanned operation in the ammunition depot. Summary of the invention

[0003] In view of the above problems existing in the prior art, an embodiment of the present invention provides a cross-arm lifting and forking transport module, which can quickly and efficiently store and retrieve shells in a magazine. The module adopts servo control during the walking, lifting and forking processes, and the cross-arm and forking telescopic mechanism can quickly realize the lifting and storage of shells. Walking and lifting can be performed in parallel, and are stable and reliable, which improves the efficiency of storing and retrieving shells and realizes unmanned operation in the magazine.

[0050] The bracket 3, the fork frame 5, the lifting platform 10 and the bomb-taking arm group 11 move linearly along the guide rail 6 under the drive of the travel servo motor 7;

[0051] The fork frame 5 performs lifting and lowering actions under the servo electric cylinder 4

[0052] The ejection arm assembly 11 is driven by the DC motor 12 to extend and retract.

[0053] The cross-arm lifting fork-picking transfer module is installed on the horizontal walking guide rail of the ship base. When executing a bomb retrieval process, the servo control box is started, and the transfer module realizes the walking action through the gear 8 and the rack 9 transmission chain under the power of the walking servo motor, and walks to the specified position.
