Problems solved by technology

[0002] With the development of shipbuilding technology, the pace of shipbuilding has gradually accelerated, and it has become normal to change from sub-station (dock) loading to general section loading. However, due to the limitations of lifting equipment and the cooperation of operators, it cannot meet the requirements of some large-scale Stable and safe lifting of objects
[0003] Usually, when hoisting and lifting the box body, the steel wire rope connecting the hook is directly connected to the lifting row. However, the rising speed of the main hook of each crane may be different, so that during the lifting process, it is very easy for each hook to There is a height difference, so that the hanging row is tilted, and the suspended objects are tilted accordingly, which will cause safety hazards in construction, pose a threat to the personal safety of the staff, and also affect the service life of the hoisting equipment

Embodiment 1

[0021] Embodiment one, combining Figure 1-4 Describe this embodiment mode, the pulley hanging row that is used for the general section hoisting of ship of the present invention, comprises hanging row box body 1, support 5, multi-directional rotating shaft 4, pulley assembly, first steel wire rope 8, second steel wire rope 10 and the third Wire rope 11.

[0022] The support 5 is fixed on the left and right sides of the upper end surface of the hanging box body 1, and the support 5 includes the fixed eye plate 2 arranged on the upper surface of the hanging box body 1, the fixed eye plate and the hanging bar Reinforcement bracket 3 at the junction of the box body. Each support 5 is fixed with a multi-directional rotating shaft 4 that can rotate forward and backward relative to the support, and the multi-directional rotating shaft 4 is fixed between two corresponding fixed eye plates. Each multi-directional rotating shaft 4 is provided with a pulley assembly that can rotate lef...

Embodiment 2

[0030] Embodiment 2. The difference between this embodiment and Embodiment 1 is that the multi-directional rotating shaft 4 is a cross-shaped rotating shaft, and the specific shape is the same as that in Embodiment 1. The difference is that the multi-directional rotating shaft in this embodiment It is integrally formed, and the two ends of the transverse shaft of the multi-directional rotating shaft are movable respectively in the eye plate holes of the fixed eye plates on both sides, and the transverse shaft of the multi-directional rotating shaft can rotate back and forth in the eye plate holes of the fixed eye plates. Other specific implementation manners are the same as those in Embodiment 1, and details are not repeated here.

Abstract

The invention discloses a pulley lifting row for ship block lifting. The pulley lifting row comprises a lifting row box, supports, multidirectional rotating shafts, pulley assemblies, a first steel wire rope, a second steel wire rope and a third steel wire rope; the supports are fixed on the left and right sides of the upper end surface of the lifting row box; each support is fixedly provided withone multidirectional rotating shaft; each multidirectional rotating shaft is provided with one pulley assembly; one end of the first steel wire rope is fixed to one crane lifting hook, and the otherend penetrates through the pulley assembly on the left side and the pulley assembly on the right side in sequence to be fixed to the other crane lifting hook; and the second steel wire rope and the third steel wire rope are hung on the lifting row box in a sleeving manner. The pulley lifting row can reduce influence on the balance degree of lifted objects by crane lifting parameters in the liftingprocess, realizes stable lifting of the lifted objects, and can satisfy lateral lifting of an inclined ship platform.

Description

technical field [0001] The invention relates to the technical field of hoisting large objects, in particular to a pulley hoisting row used for hoisting the general section of a ship. Background technique [0002] With the development of shipbuilding technology, the pace of shipbuilding has gradually accelerated, and it has become normal to change from sub-stations (docks) to general sections. However, due to the limitations of lifting equipment and the cooperation of operators, some large-scale Stable and safe hoisting of objects. [0003] Usually, when hoisting and lifting the box body, the steel wire rope connecting the hook is directly connected to the lifting row. However, the rising speed of the main hook of each crane may be different, so that during the lifting process, it is very easy for each hook to There is a height difference, so that the hanging row is tilted, and the suspended objects are tilted accordingly, which will cause safety hazards in construction, pos...
