Description

Technical Field

[0001] The invention relates to a hoisting or lifting device for a reserved joint section in the construction of a large-span steel structure bridge, in particular to a connecting lifting lug for integrally lifting a large-segment rod system component. Background Art

[0002] With the rapid development of construction technology and society, the architectural appearance of bridges has become more beautiful and the structural stress has become more innovative. Existing large-span steel structure bridges are mostly constructed by segmented processing and installation, with the joint section reserved for hoisting or lifting. During the lifting construction of the joint section of the bridge, the connection between the lifted component and the lifting system generally adopts a shoulder beam to support the lifted component. During the construction of this method, it is easy to increase the workload of high-altitude operations. When the structure of the steel structure beam is complex, the problems of inconvenient installation of the shoulder beam and high difficulty in resuming construction after the structure is opened gradually become prominent. How to solve such problems, reduce the amount of high-altitude operations, and reduce construction risks are the directions of our research. Summary of the invention

[0003] The present invention aims to provide a connecting lifting lug for the overall lifting of large-segment rod system components, which adopts an anchoring device composed of an anchoring system and a lifting lug system. The anchoring device is simple to process and install, and is easy to operate, which further reduces the amount of high-altitude operations, reduces construction safety risks, reduces construction costs, and improves construction efficiency.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: a connecting lifting lug for overall lifting of large-segment rod system components, including an anchoring system and a lifting lug system, an anchoring device for connecting the lifted component with the lifting system, which is composed of an anchoring system directly connected to the main load-bearing rod of the lifted component and a lifting lug system fixed to the anchoring system.

[0005] Furthermore, the anchoring system is composed of an anchoring web and an anchoring web stiffening plate. The anchoring web is the main load-bearing rod of the anchoring device and is welded and fixed to the main load-bearing rod of the lifted component through the anchoring web stiffening plate.

[0006] Furthermore, the webs are anchored, and the web spacing and size are adjusted according to the size of the main load-bearing rods of the lifted component; the web stiffening plates are anchored, and the number and size positions are adjusted according to the positions of the cross diaphragms of the main load-bearing rods of the lifted component.

[0007] Furthermore, the lifting ear system consists of a heart-shaped lifting ear plate, a lifting ear plate stiffening plate, a bottom anchor pin shaft hole reinforcement plate, a lifting ear plate partition, and a lifting ear plate web. The heart-shaped lifting ear plate is connected to the anchor web and is used for the bottom anchor installation of the lifting device and to ensure the structural stability when the lifting component is lifted.

[0008] Furthermore, the heart-shaped lifting ear plate converts the anchor device from being subjected to force in the longitudinal direction of the bridge to being subjected to force in the transverse direction of the bridge, making the construction force more reasonable, thereby improving the safety and overall stability of the lifting construction of the lifted component.

[0009] Furthermore, the lifting lug system adjusts the size of the heart-shaped lifting lug plate according to the web spacing, adjusts the size of the lifting lug opening according to the size of the bottom anchor pin shaft of the lifting system, and then adjusts the overall structure of the lifting lug system to adapt to various sizes of lifted components.

[0010] Furthermore, the entire structure of the anchoring device is made by welding steel plates.

[0011] The beneficial effects of the present invention are:

[0012] The anchoring device for connecting the lifted component with the lifting system of the present invention is composed of an anchoring system and a lifting lug system, has a simple manufacturing process, is easy to install and use, reduces the amount of aerial work, reduces construction safety risks, reduces construction costs, and improves construction efficiency. The entire structure is made of welded steel plates, and has strong overall stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is a further description of the implementation methods of the present invention in conjunction with specific implementation cases.

[0018] like Figures 1 to 4 As shown, a connecting lug for integrally lifting a large-segment rod system component of the present invention comprises an anchoring system and a lug system. The anchoring system is directly connected to the main force-bearing rod of the lifted component and the lug system is fixed to the anchoring system to form an anchoring device for connecting the lifted component with the lifting system.

[0019] like Figure 2 As shown, the anchoring system is composed of an anchoring web 1 and an anchoring web stiffening plate 101. The anchoring web 1 is the main load-bearing member of the anchoring system, and is welded and fixed to the main load-bearing member of the lifted component through the anchoring web stiffening plate 101.

[0020] In the anchoring system, the web spacing and size of the anchoring web 1 can be adjusted according to the size of the main load-bearing rod of the lifted component; the number and size of the anchoring web stiffening plate 101 can be adjusted according to the position of the cross diaphragm of the main load-bearing rod of the lifted component.

[0022] The heart-shaped lifting lug plate 2 and the anchoring web 1 are used for installing the bottom anchor of the lifting device and ensuring the structural stability when the lifting component is lifted.

[0023] The setting of the heart-shaped lifting ear plate 2 converts the anchoring device from being subjected to force in the longitudinal direction of the bridge to being subjected to force in the transverse direction of the bridge, making the construction force more reasonable, thereby improving the safety and overall stability of the lifting construction of the lifted component.

[0024] The lifting lug system can adjust the size of the heart-shaped lifting lug plate 2 according to the web spacing, adjust the size of the lifting lug opening according to the size of the bottom anchor pin shaft of the lifting system, and then adjust the overall structure of the lifting lug system to adapt to various sizes of lifted components.

[0025] The whole structure of the anchoring device is made of welded steel plates, which is convenient to obtain and has a simple manufacturing process.

[0027] 1) Make and process anchoring system, such as Figure 2 ;

[0028] 2) Make and process the lifting lug system, such as Figure 3 ;

[0029] 3) The anchor system and the lifting lug system are welded as a whole. Figure 1 ;

[0030] 4) Install the anchor device to the main load-bearing rod of the north lifting component and weld it into a whole.

[0031] The above implementation cases are only used to illustrate the technical process and principle of the present invention, in which the size and connection method of each component can be changed according to the size of the main force-bearing rod of the lifted component and the size of the bottom anchor pin. Any equivalent transformation and improvement based on the technical solution of the present invention to achieve the effect that the present invention should embody should not be excluded from the protection scope of the present invention.
