Description

Technical Field

[0001] This utility model relates to the field of gantry crane processing technology, and in particular to an automatic positioning and feeding device for gantry cranes used in scrap steel processing. Background Technology

[0002] The gantry crane automatic positioning and feeding device for scrap steel processing is an automated handling equipment used in scrap steel recycling, smelting or processing production lines. It is mainly used for efficient and accurate grabbing, positioning and conveying of scrap steel materials. Its core function is to replace traditional manual or semi-automatic operation and improve the efficiency, stability and safety of scrap steel feeding.

[0003] In the scrap steel processing process, traditional gantry crane loading devices usually rely on manual operation for positioning and clamping, which has problems such as inaccurate positioning, low efficiency, and significant safety hazards. Although the electromagnetic chucks in the existing technology can attract scrap steel, they are prone to falling off due to shaking when handling heavy or irregularly shaped scrap steel. In addition, traditional devices lack effective auxiliary fixing mechanisms, making it difficult to adapt to the clamping requirements of scrap steel of different sizes, thus affecting processing efficiency.

[0004] Therefore, how to provide an automatic positioning and feeding device for gantry cranes used in scrap steel processing is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

The device achieves precise lateral positioning by driving a gear and rack via a first rotating motor. A lifting motor, in conjunction with a winding roller, controls the electromagnetic plate for smooth lifting and lowering. A second rotating motor drives an auxiliary clamping mechanism to secure the scrap steel. The overall structure is compact and highly automated, significantly improving feeding efficiency and safety while reducing manual labor intensity. It is suitable for various scrap steel processing scenarios, thus solving the problems mentioned in the background section.

[0006] An automatic positioning and feeding device for gantry cranes used in scrap steel processing, according to an embodiment of the present invention, includes a gantry crane vertical rod and a fixing plate.

[0026] Working principle:

[0027] First, starting the first rotating motor 3 drives the rotating gear 13 at the output end to rotate. The rotation of the rotating gear 13 engages with the rack plate 15 on the outer wall, thereby driving the movable sleeve 4 to move left and right. The movement of the movable sleeve 4 drives the movable box 5 at the bottom to move. Next, starting the lifting motor 10 drives the second driving gear 21 at the output end to rotate. The rotation of the second driving gear 21 drives the driven gear 22 on the outer wall to mesh and rotate. The rotation of the second driving gear 21 and the driven gear 22 drives the lifting rope 16 on the outer wall of the winding roller 20 to rotate. The rotation of the lifting rope 16 drives the electromagnetic plate 17 at the bottom to move downward. Then, the electromagnetic plate 17 is activated to attract and fix the scrap steel to be moved. Finally, starting... The second rotating motor 19 drives the first driving gear 7 to rotate. The rotation of the first driving gear 7 drives the bottom transmission gear 8 to rotate. The rotation of the transmission gear 8 drives the outer wall semi-ring gear 18 to rotate. The rotation of the semi-ring gear 18 and the transmission gear 8 drives the outer wall connecting rod 9 to rotate.

In conjunction with the rotation of the second connecting rods 14 on both sides, the auxiliary fixing rods 11 on both sides can rotate inward, thereby assisting in clamping and fixing the scrap steel plate. Then, by driving the lifting motor 10 to rotate in the opposite direction, the lifting rope 16 can drive the bottom electromagnetic plate 17 to retract upward, which can move the scrap steel to facilitate subsequent processing of the scrap steel.
