Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it should be noted that, unless explicitly stated or limited otherwise, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, such as "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Example 1:
an electric hoist double-beam crane trolley for improving lifting height comprises a cross beam 8; an electric hoist 1 is arranged above the cross beam 8; an opening 14 is formed in the cross beam 8 below the rotating shaft of the electric hoist 1; a wire rope is arranged on the rotating shaft of the electric hoist 1; a hanging seat 6 is hung below the coiled rope; a hook 7 is arranged below the hanging seat 6; a pulley 11 is arranged below the cross beam 8; and a lifting device is arranged between the cross beam 8 and the pulley 11.
The lifting device comprises a support column 9; the upper ends of the pillars 9 penetrate through the cross beam 8; the strut 9 is provided with an external thread structure; the pillar 9 at the lower end of the cross beam 8 is connected with a threaded seat 15 through threads. The threaded seat 15 and the cross beam 8 are both provided with connecting bolt holes; the connecting bolt hole is provided with a pin 16. The connecting bolt holes are arranged in a plurality and are uniformly distributed by taking the supporting columns 9 as axes.
The coil ropes comprise a first coil rope 2 and a second coil rope 3; the middle part of the rotating shaft is provided with a guide plate 4; the guide plate 4 is provided with a slotted hole 5; the first coil rope 2 and the second coil rope 3 are wound from two ends of the rotating shaft to the inner end and penetrate through the slotted hole 5.
