工业机械滑轮装置白底概念图

3:4竖幅，浅灰白色无缝背景，正视角居中展示一件灰黑色工业机械装置。上部与下部分别有一枚巨大的灰色圆形圆盘，表面呈哑光铸铁或石质质感，边缘有厚实环形结构；中部两根灰褐色长条横梁水平贯穿并位于圆盘前方，横梁表面带木纹质感。装置中央是深灰金属机匣，露出铜色线圈和齿轮结构，右侧有圆柱形轴承与螺栓。下方由多根细黑线缆呈V形连接一个小型圆形滑轮，滑轮表面有木纹和十字交叉加固条，中央轴心突出，底端延伸出一根黑色金属尖杆。正面平视、产品展示构图，柔和均匀的棚拍光线，金属与木材纹理清晰，3D工业机械概念设计，写实材质，蒸汽朋克机械感。

Vertical 3:4 aspect ratio, light gray-white seamless background, front view centered on a dark gray industrial mechanical device. At the top and bottom are two large gray circular discs with matte cast-iron or stone-like surfaces and thick ring-shaped edges; across the middle, two long gray-brown horizontal beams with wood-grain texture pass in front of the discs. The center is a dark gray metal housing revealing a copper-colored coil and gear structure, with cylindrical bearings and bolts on the right. Below, several thin black cables form a V-shape connecting to a small circular pulley with wood-grain texture, cross-braced reinforcement bars, a protruding central hub, and a black pointed metal rod extending downward. Front orthographic product-display composition, soft even studio lighting, clear metal and wood textures, 3D industrial mechanical concept design, realistic materials, steampunk mechanical feel.
