The invention provides a load shedding support for a main beam of a portal crane, and relates to the technical field of portal cranes. The portal crane main beam load shedding support comprises a main beam, a cavity is formed in the middle of the main beam, two motors are fixedly connected to the right side of the interior of the cavity, the output ends of the motors are fixedly connected with rotating rods, and the left ends of the rotating rods penetrate through the main beam and are fixedly connected with a first winding wheel; a first bevel gear is fixedly connected to the middle of the rotating rod on the front side. A first winding wheel rotates to wind a second connecting rope, the second connecting rope fixes the two ends of the light anti-drag material, meanwhile, a second winding wheel is matched to wind the corresponding first connecting rope, the first connecting rope fixes the middle of the light anti-drag material, and therefore the light anti-drag material is not prone to falling off, and the size is convenient to adjust; therefore, the damping device adapts to light materials with different damping shapes, can be rolled when not in use, and is more convenient to use.

    本发明提供一种门式起重机主梁减载支架,涉及门式起重机技术领域。该门式起重机主梁减载支架,包括主梁,所述主梁的中部设置有空腔,所述空腔的内部右侧固定连接有两个电机,所述电机的输出端固定连接有转杆,所述转杆的左端贯穿主梁并固定连接有收卷轮一,前侧所述转杆的中部固定连接有锥齿轮一。通过收卷轮一转动进行收卷连接绳二,使连接绳二将轻型减阻材料的两端进行固定,同时再配合收卷轮二收卷对应的连接绳一,使连接绳一对轻型减阻材料的中部进行固定,从而使轻型减阻材料不容易发生脱落,方便调节大小,从而适应不同的减阻外形的轻质材料,不使用时还可以收卷,使用起来更为方便。
