Problems solved by technology

At present, two methods are usually used to adjust the three-dimensional space state of the component when hoisting large-volume special-shaped steel structure components: one is to calculate the position of the lifting point and the length of the wire rope, but there are differences between the theoretical calculation and the actual situation, and the accuracy is difficult to guarantee; the other is to use the inverted Chains and pulleys cooperate to adjust the length of the sling, but there are problems such as complicated operation and large labor consumption

Embodiment 1

[0029] Such as figure 1 As shown, in this embodiment, the number of the steel wire ropes 2 is three, the number of the hydraulic pull pumps 3 is two, and one end of the three steel wire ropes 2 is connected with the hook device 1, two of which The other end of the wire rope 2 is respectively connected to one end of the two hydraulic pull pumps 3, the other end of the other wire rope 2 is fixed to one side of the member 4, and the other ends of the two hydraulic pull pumps 3 are respectively fixed at both ends of the member 4.

[0030] Further, when using the hoisting rigging provided in this embodiment, in step five, when adjusting the height above the ground of multiple positions on the member 4, when the member 4 needs to rotate along the X-axis direction , the two hydraulic pull pumps 3 extend and shrink respectively at the same time, and the amount of expansion and contraction is the same; when the member 4 needs to rotate along the Y-axis direction, the two hydraulic pul...

Embodiment 2

[0032] Such as figure 2 As shown, in this embodiment, the number of the steel wire ropes 2 is three, the number of the hydraulic pull pumps 3 is two, and one end of two steel wire ropes 2 in the three steel wire ropes 2 is connected with the hook device 1 , the other end of which is respectively connected to one end of the two hydraulic pull pumps 3, and the other steel wire rope 2 is passed through the hook device 1, and its two ends and the other ends of the two hydraulic pull pumps 3 are respectively Fixed on the four corners of the member 4 , the other ends of the two hydraulic pull pumps 3 are located on the same side of the member 4 .

[0033] Further, when using the hoisting rigging provided in this embodiment, in step five, when adjusting the height above the ground of multiple positions on the member 4, when the member 4 needs to rotate along the X-axis direction , the two hydraulic pull pumps 3 extend and shrink respectively at the same time, and the amount of expa...

Embodiment 3

[0035] Such as image 3 As shown, in this embodiment, the number of the steel wire ropes 2 is four, the number of the hydraulic pull pumps 3 is four, and one end of the four steel wire ropes 2 is connected to the hook device 1, and its The other ends are respectively connected to one ends of the four hydraulic pull pumps 3 , and the other ends of the four hydraulic pull pumps 3 are respectively fixed on the four corners of the member 4 .

[0036] Further, when using the hoisting sling provided in this embodiment, in the fifth step, when adjusting the height above the ground of multiple positions on the member 4, it is only necessary to adjust the expansion and contraction of each hydraulic pump 3 one by one , to complete the three-dimensional state adjustment of the component 4 .

Abstract

The invention provides a hoisting rigging and a hoisting method thereof. On the basis of the prior art, a hydraulic pull pump is additionally arranged; the main effect of the hydraulic pull pump is used for adjusting the length of a steel wire rope by virtue of self retraction, so that a three-dimensional space state of a member meets the hoisting requirements. According to the hoisting rigging and the hoisting method thereof, the single set of the rigging is used so as to realize the adjustment of the three-dimensional space state of the member; the adjusting precision is high and the whole hoisting precision of the member is improved.

Description

technical field [0001] The invention relates to the technical field of component engineering construction, in particular to a hoisting sling and a hoisting method thereof. Background technique [0002] With the development of society, more and more buildings use novel steel structural components to replace the original concrete structural components, and their scale and shape are becoming larger and more diversified. At present, two methods are usually used to adjust the three-dimensional space state of the component when hoisting large-volume special-shaped steel structure components: one is to calculate the position of the lifting point and the length of the wire rope, but there are differences between the theoretical calculation and the actual situation, and the accuracy is difficult to guarantee; the other is to use the inverted The chain and the block of pulleys cooperate to adjust the length of the sling, but there are problems such as complicated operation and large l...
