Anti-swinging, quakeproof and electromagnetic lifting crane

Abstract

The invention discloses an anti-swinging, quakeproof and electromagnetic lifting crane. The crane comprises a bridge and an anti-swinging and quakeproof trolley; the bridge is driven by a motor; the anti-swinging and quakeproof trolley moves along the bridge; a first drum is arranged on the anti-swinging and quakeproof trolley; the crane further comprises an anti-shaking lifting tool; the anti-shaking lifting tool comprises a #-shaped rotating frame; a second drum is arranged on the rotating frame; pulleys are arranged on all the bulging surfaces of the rotating frame; four steel wire ropes are arranged among the pulleys, the first drum and the second drum and are intertwined in a forwards, backwards, leftwards and rightwards crossing manner; the rotating frame is restrained correspondingly in the front, back, left and right directions; a rotating motor is arranged in the center of the rotating frame; and a hanging beam rotates on an output shaft of the rotating motor. The crane is simple and reasonable in structure and convenient to use, the four steel wire ropes are arranged among the pulleys, the first drum and the second drum and are intertwined in the forwards, backwards, leftwards and rightwards crossing manner, the rotating frame is restrained correspondingly in the front, back, left and right directions, and the function of preventing shaking in the four directions is realized.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to an anti-sway anti-vibration electromagnetic hoisting crane. Background technique [0002] The traditional electromagnetic hoisting crane, the main hoisting wire rope is wound with 8 ropes or 16 ropes, the structure is complicated, the manufacturing process is cumbersome, and it cannot really play the anti-shake and anti-vibration function, such as figure 1 , figure 2 As shown, the wire rope passes through the drum guide pulley, which cannot achieve the anti-shake and shock-absorbing effect. Such as image 3 , Figure 4 As shown, the steel wire rope is guided to the lower pulley through four sets of drum guides. Its structure is complicated, the manufacturing process is cumbersome, and it is difficult to install, especially in subsequent maintenance; and the anti-shake and shock-absorbing effect is not significant. [0003] To sum up, existing anti-sway and anti-vi...

[0002] The traditional electromagnetic hoisting crane, the main hoisting wire rope is wound with 8 ropes or 16 ropes, the structure is complex, the manufacturing process is cumbersome, and it cannot really play the anti-shake and anti-vibration function, such as figure 1 , figure 2 As shown in the figure, the wire rope passes through the drum guide pulley, which cannot achieve the anti-shake and shock-absorbing effect

like image 3 , Figure 4 As shown, the steel wire rope is guided to the lower pulley through four sets of drum guides. Its structure is complicated, the manufacturing process is cumbersome, and it is difficult to install, especially in subsequent maintenance; and the anti-shake and shock-absorbing effect is not significant.

[0003] To sum up, the existing anti-sway and anti-vibration electromagnetic cranes have problems such as poor anti-sway and anti-vibration effects, high anti-sway costs, and inability to actually meet user requirements, high production costs, and difficult installation and maintenance.
