Problems solved by technology

[0004] Disadvantages in the prior art: the compensation system is connected in series with the hoisting mechanism, and it is necessary to change the direction of the wire rope and increase the winding of the wire rope. Gravity moment, increasing the axial load component of the boom
The compensation system is fixedly connected to the slewing base of the hoisting machinery. When the hoisting objects are different, it is inconvenient to quickly debug or replace the system
When the compensation system adopts the active control method, the structure complexity is high, which greatly increases the manufacturing cost and maintenance cost, and the practicability is not strong

Embodiment Construction

[0031] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0032] like Figure 2 to Figure 6 As shown, the embodiment of the present invention provides a sling for hoisting a load. The sling includes: a first sling platform 6 , a second sling platform 1 and a buffer device. The second spreader platform 1 is arranged movably along the longitudinal direction of the first spreader platform 6 . The first spreader platform 6 is provided with an upper platform 61 and a hoisting part fixedly connected with the upper platform 61 to be connected with the hoisting object; the second spreader platform 1 is used for connecting with a hoisting rope and is arranged at the lower part of the upper platform 61; The device is arranged between the second spreader platf...

Abstract

The invention provides a hoisting appliance and a crane with the same. The hoisting appliance is used for hoisting hoist objects and comprises a first hoisting appliance platform (6), a second hoisting appliance platform (1) and a buffer unit. An upper platform (61) and a hoisting portion for being connected with hoist objects are arranged on the first hoisting appliance platform (6), and the hoisting portion is fixedly connected with the upper platform (61); the second hoisting appliance platform (1) used for being connected with a hoisting rope is arranged on the lower portion of the upper platform (61) and arranged movably along the longitudinal direction of the first hoisting appliance platform (6); and the buffer unit is arranged between the second hoisting appliance platform (1) and the upper platform (61). According to the hoisting appliance and the crane with the same, displacement responses and acceleration responses of hoist objects in the vertical direction can be decreased, vibration of hoisting objects in the vertical direction can be reduced, and accordingly, impacts imposed on the hoisting objects are reduced, the tension applied to the hoisting rope is stabilized, and the load stability is improved.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to a spreader and a crane with the spreader. Background technique [0002] During the hoisting process of large-scale offshore platform hoisting machinery or port hoisting machinery, due to wind and waves, jib rotation and pitching, etc., the hoisting objects will vibrate obviously in the vertical direction, and will also vibrate obviously in the horizontal direction. swing. When the vibration amplitude is large, on the one hand, it is not conducive to the rapid and stable completion of the hoisting task, which affects work efficiency; safety hazard. For the sway in the horizontal direction, since the partial stiffness of the wire rope-slinging object system in the horizontal direction is very small, it is generally necessary to change the vertical lifting method of the wire rope or apply additional horizontal resistance to the wire rope-slinging object system to achieve anti-swa...
