Description

Technical Field

[0001] The utility model relates to the technical field of steel coil packaging, and more specifically to a lifting saddle device for a walking beam. Background Art

[0002] In cold rolling production lines, finished steel coils, including color coating lines, galvanizing lines, etc., often use walking beam conveyors. The characteristic of walking beam transportation is that it is intermittent step-by-step motion, which is conducive to the outer packaging and coding of steel coils. However, sometimes some packaging processes require the steel coils to be raised to a certain height to have enough space for operation, or during transportation, large-width steel coils need to be lifted to a certain height to pass certain specific equipment on both sides of the walking beam. The current technology provided is to add a lifting mechanism on one side of the walking beam, or to use a crane for lifting. The former solution has complex and bulky equipment and increases the construction cost of civil engineering. The latter solution increases the frequent use of the crane and requires manual support, which increases the workload and the risk factor.

[0003] After searching, the patent with publication number CN216425301U provides a step-beam lifting saddle. This design focuses on solving the problem that the lifting mechanism is subject to greater gravity when lifting the steel coil due to the inability of the support mechanism itself to rise and fall, which is easy to cause damage to the inside of the equipment over time. The patent with publication number CN208104555U provides a step-beam rotating saddle overall quick replacement device, a groove-shaped notch is provided on the end of the step-beam close to the saddle; a circle of protrusions is provided on the inner wall of the groove-shaped notch near the upper edge, and a step structure is formed between the edge of the protrusion structure and the inner wall of the groove-shaped notch; the upper and lower parts of the saddle rotating device are respectively fixedly connected to an upper positioning plate and a lower positioning plate; a positioning block is provided on the outer side of the saddle device, and matching positioning holes are provided on the positioning block and the end of the step-beam; this design focuses on achieving quick replacement of bearings. This type of design is obviously not applicable to the production difficulties mentioned above. Utility Model Content

[0021] (2) The lifting saddle device of the utility model has a cross-shaped groove in the middle of the pad, and the two sides are inclined in a V-shape, which is convenient for bringing in the steel coil bundling belt and is applicable to a wide width of steel coils; and the pad is made of non-rigid material, which effectively avoids damage to the surface quality of the steel coil during transportation.

[0022] (4) In the lifting saddle device of the utility model, the top of the push head is spherical. Whether in the manufacturing process or the installation process, a slight deflection will not affect the contact effect between the push head and the connecting rod, thereby reducing the failure rate.

[0023] (5) The lifting saddle device of the utility model is provided with a guide assembly, and the guide rod is inserted into the sliding sleeve. The guide rod and the sliding sleeve are clearance-matched to ensure that the guide rod can slide freely up and down in the sliding sleeve. In addition, the sliding sleeve is made of self-lubricating material, thereby ensuring that when the lifting power pushes the saddle assembly to move back and forth in a straight line up and down along the stepping beam sleeve, there will be no wear resistance between steel and steel.
