The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2, the utility model discloses major diameter pipeline poling construction structures based on steel construction gallows, including being used for hoisting pipeline 2's first hoisting device 3 and draw gear 4 of dragging pipeline 2, first hoisting device 3 is fixed in upper floor, draw gear 4 and first hoisting device have certain horizontal interval between 3 and locate upper floor or lower floor on, be equipped with in the horizontal interval and be located upper floor, supply draw gear 4 to drag a plurality of gallows 1 that pipeline 2 walked, interval between two gallows 1 of a gallows 1 of looks interval is less than pipeline 2's length.
In this embodiment, form the construction structures of installation pipeline 2 after installing a plurality of gallows 1 and hoist and mount piece in advance, make a plurality of pipelines 2 can walk and remove to the design position on gallows 1 one by one, and need not to install gallows 1, install and demolish hoist and mount piece circularly and reciprocally, this structure utilizes the good rigidity of steel construction gallows 1, stability and suitable interval, utilize and drag the construction to realize pipe in batches, improve the speed of pipeline 2 hoist and mount by a wide margin, and the safe risk also improves in step, only need set up a small amount of hoisting points when the structure is laid, and need not to circulate the installation and demolish hoist and mount piece, the setting of a lot of hoisting points has been reduced, reduce the destruction to the floor, and a large amount of manpowers and time have been practiced thrift.
The structure further comprises a second lifting device 7 used for lifting the pipeline 2 away from one end of the traction device 4, the second lifting device 7 is located on one side, away from the plurality of lifting frames 1, of the first lifting device 3, the second lifting device 7 is connected to one end, away from the traction device 4, of the pipeline 2 and lifts the pipeline 2, and the stability of the lifting pipeline 2 is guaranteed by matching the first lifting device 3 and the traction device 4 as shown in fig. 3. In this embodiment, the second hoisting device 7 is used as an auxiliary hoisting member, and the second hoisting device 7 can be an electric hoist with low cost.
In this embodiment, the first hoisting device 3 and the traction device 4 are hoists, and each hoist includes a winding mechanism and a cable that is wound and unwound by the winding mechanism.
Draw gear 4 locates the floor of lower floor, and the top of draw gear 4 is equipped with the pulley 9 that sets firmly on the floor of upper floor, and draw gear 4's cable 6 is slided and is located and wear to locate again on pulley 9 and draw pipeline 2 in gallows 1, changes draw gear 4's cable 6's direction through this pulley 9, and pulley 9 has also reduced the frictional force with the cable, and the resistance is littleer when making and dragging pipeline 2. In some other embodiments, the traction device may be installed on the upper floor, so that the traction direction does not need to be changed by using the pulley, and the traction device 4 is installed on the lower floor, which is more convenient to install than the traction device installed on the upper floor, thereby avoiding the risk of dropping.
The two ends of the pipeline 2 are respectively and fixedly provided with a hook for connecting the first hoisting device 3 and the traction device 4, so that the connection of the guy cable 5 of the first hoisting device 3 and the guy cable 6 of the traction device 4 with the pipeline 2 is facilitated.
In the structure, the pipeline 2 is installed after all the hangers 1 are installed, so that the circular cross operation does not exist. When the pipeline lifting device is used, as shown in fig. 1, the stay cable 5 of the first lifting device 3 is connected to the 1/3 position of the first end of the pipeline 2, the stay cable 6 of the traction device 4 is connected to the hook at the first end of the pipeline 2, the first end of the pipeline 2 is lifted by the first lifting device 3, the pipeline 2 is dragged by the traction device 4, the first end of the pipeline 2 is placed on the side-most lifting frame 1, and the stay cable 6 of the traction device 4 is tensioned to prevent the pipeline 2 from falling; as shown in fig. 2, the first hoisting device 3 is placed at the second end of the pipeline 2 to raise the second end of the pipeline 2, in the process, if the pipeline 2 is too long, the first hoisting device 3 is hoisted unchanged, the guy cable 8 of the second hoisting device 7 can be connected to the second end of the pipeline 2, the first hoisting device 3 and the second hoisting device 7 are used for hoisting together, and after the second end of the pipeline 2 is hoisted, the guy cable 6 of the traction device 4 is gradually contracted for hoisting in a matching manner, so that the pipeline 2 gradually enters the hoisting frame 1; as shown in fig. 3, when the pipe 2 enters the hanger 1 for a sufficient length, the connection between the second lifting device 7 and the pipe 2 can be disconnected, and because the distance between the two hangers 1 spaced by one hanger 1 is less than the length of the pipe 2, the pipe 2 is positioned on the two hangers 1 at any time when passing through the hangers 1, so that the pipe 2 is ensured not to fall when passing through the hangers 1, and the pipe 2 can be set to a position by only using the contraction of the guy cable in the traction device 4 to drag the pipe 2.
After 2 hoists the completion, fix a position according to the trompil position on the gallows 1, 2 groups of pipelines are fixed to the first spot welding after accomplishing, lead to long 2 axialities of inspection pipeline and the mouth of pipe whether the wrong limit, use the parallels to eliminate the difference in height to the mouth of pipe of wrong limit, accomplish the mouth of pipe full weld at last, 2 welding of pipeline should be strictly carried out according to design and standard requirement to accomplish the installation of pipeline.
