Description

Technical Field

[0001] The utility model belongs to the technical field of cooling bed modification for a plate production line, and particularly relates to a cooling bed loading and unloading height adjustment device. Background Art

[0002] The loading and unloading device of the medium and thick plate cooling bed is mainly composed of a rotating lifting beam, chain, connecting rod, crank and hydraulic cylinder. A set of loading and unloading device has a total of 22 sets of kits. One end of the lifting beam is fixed with the bracket as the fixed point. The hydraulic cylinder drives the transmission shaft to rotate and drives the connecting rod and lifting beam connected to it to rise and fall as a whole.

[0003] When the steel plate reaches the input roller of the cooling bed, the loading and unloading lifting mechanism rises to the highest position. At this time, the chain lifts the steel plate 20mm above the roller surface, and the chain rotates to transport the steel plate forward and sends the steel plate to the roller. During use, there is rolling friction between the chain and the lifting beam. During long-term use, the chain and the lifting beam have different degrees of wear, resulting in the chain elevation being 15-20mm higher than the roller surface when in the highest position. In severe cases, some chains are lower than the roller surface, causing the steel plate to scratch against the roller, and the steel plate to tilt or even slip during transportation. The same is true for unloading, which seriously affects production.

[0004] To this end, the utility model designs a combined device for separately adjusting the elevation of the lifting beam and the chain, ensuring that the elevation of the lifting beam and the chain can be adjusted in time after wear, without the need to replace the spare parts as a whole, saving a lot of spare parts replacement costs and time.

[0029] Preferably, the thickness of the adjusting gasket is 1 mm.

[0030] The following is a detailed analysis of the design advantages for each technical feature:

[0031] Split connecting rod and first adjusting shim:

[0032] Design advantages: The split connecting rod design allows the connecting rod to be divided into an upper connecting rod and a lower connecting rod, which are fastened together by the first connecting bolt. This design allows the connecting rod to be easily disassembled and reinstalled when it is worn or needs adjustment. The adjustment pads are set between the horizontal connection surfaces of the connecting rod. By increasing or decreasing the number of the first adjustment pads, the height of the lifting beam can be fine-tuned. This fine-tuning method is both accurate and convenient, without the need to replace the entire connecting rod or perform complex mechanical adjustments, reducing maintenance costs and time.

[0033] Lifting beam hinge base and second adjusting shim:

[0034] Design advantages: The lifting beam articulated base is the supporting structure of the lifting beam. Its stability and adjustability are crucial to the working effect of the lifting beam. The base and the bracket are fastened with a second connecting bolt to ensure the stability of the structure. Adjustment pads are set between the base and the bracket to adjust the overall height of the lifting beam to adapt to steel plates of different specifications or degrees of wear. This design improves the adaptability and flexibility of the equipment and extends the service life of the equipment.

[0035] Through hole design on the adjusting gasket:

[0036] Design advantages: The through holes set on the first and second adjusting gaskets facilitate the passage and tightening of the first and second connecting bolts, making the installation and removal of the gaskets more convenient. The design of the through holes also ensures that the first and second connecting bolts can firmly fix the adjusting gaskets and related components, preventing the adjusting gaskets from shifting or falling off during use, thereby improving the stability and safety of the equipment.

[0037] Adjust the gasket thickness to 1mm:

[0038] Design advantages: 1mm was chosen as the thickness of the adjustment shim in consideration of the adjustment accuracy and the ease of processing. The thickness of 1mm can achieve fine elevation adjustment, and is easy to process and mass produce, reducing manufacturing costs. At the same time, the thinner shim also reduces the need for installation space, making the entire adjustment device more compact and efficient.

[0039] In summary, the design of each technical feature fully considers the stability, adjustability, convenience and economy of the equipment, so that the cooling bed loading and unloading elevation adjustment device has excellent performance and broad application prospects.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
