Description

Technical Field

[0001] This utility model belongs to the field of bridge construction, and in particular relates to a quick fixing device for temporary connection of arch rib segments. Background Technology

[0002] The rapid fixing device for temporary connections of arch rib segments is a key component in the construction of arch bridges. When arch rib segments are hoisted to their designated locations, the rapid fixing device can quickly position and initially secure the segments, creating favorable conditions for subsequent precise splicing and greatly improving the construction efficiency of segment connections. When the construction site encounters sudden severe weather or unexpected disturbances, the device, with its stable structure and reliable connections, provides strong constraints on the arch rib segments, maintaining the overall stability of the arch rib and avoiding the risk of segment misalignment or falling due to swaying. Furthermore, in complex and changing construction environments, the rapid fixing device can effectively control the relative displacement between arch rib segments, ensuring uniform stress distribution in each segment and guaranteeing that the stress on the arch rib structure meets design requirements. In short, a high-quality rapid fixing device and its proper use are crucial guarantees for ensuring the smooth and safe progress of arch bridge construction.

[0003] Current technical challenges in arch rib segment installation:

[0004] (1) Currently, the installation of arch rib segments is mainly achieved through spot welding and temporary diagonal bracing. Spot welding relies on large welding equipment, which is inefficient for high-altitude operations and can easily damage the main structure in the heat-affected zone. Disassembly requires cutting and damaging the welds, which seriously affects the continuity of construction. Furthermore, spot welding is performed point by point, and the connection between points is relatively independent, resulting in insufficient overall integrity of the arch rib connection. Under complex external forces, connection failure is likely to occur, thereby increasing construction risks. On the other hand, the temporary diagonal bracing system occupies a large space and is difficult to deploy in complex terrain or narrow construction areas. Moreover, its rigid support cannot adapt to the dynamic deformation during the hoisting of the arch rib, which can easily lead to misalignment between segments.

[0005] (2) During the installation process, the installed fixing components are prone to loosening and displacement between the arch rib segments due to complex factors such as on-site vibration and strong winds. At the same time, some fixing devices are not designed with sufficient consideration for environmental adaptability, and their stability is greatly reduced when faced with sudden severe weather. Once the fixing device fails, the arch rib segments will lose their restraint, which may lead to serious safety accidents and pose a great threat to the safety of on-site construction personnel and equipment.

[0006] (3) Currently, the installation of arch rib segments mainly relies on the experience of construction personnel or the use of traditional measuring tools for positioning, which results in significant human error. Deviations in the installation position will affect the connection between arch rib segments, causing uneven stress on the arch rib structure and local stress concentration. In severe cases, it may even lead to the instability of the entire arch rib structure, posing a huge safety hazard to the quality of the arch bridge and its subsequent operation.

[0012] Furthermore, the connecting rod bolt fixing device includes a connecting rod, a washer, and a bolt. Both ends of the connecting rod pass through the mounting holes of the semi-circular sleeve, and the washer and bolt pass through both sides of the mounting holes.

[0013] Furthermore, the electromagnet adsorption device includes a motor, two annular electromagnets, four block electromagnets, and a motor mounting platform. The motor mounting platform is bolted to the outside of the semi-circular sleeve, and the motor is bolted to the motor mounting platform.

The motor mounting platform provides a position for the motor to be fixed to the arch rib fixing sleeve. Attached Figure Description

When temporarily connecting the arch ribs, firstly, the electromagnet adsorption device 3 (including motor 31, annular electromagnet 32a, block electromagnet 32b and motor mounting platform 33) is bolted onto the semi-circular sleeve 11. At the same time, the rubber anti-slip pad is also installed on the semi-circular sleeve 11. Then, the two semi-circular sleeves 11 are hoisted to the fixed position of the arch rib 41a by the hoisting handle 14 installed on the sleeve. The electromagnet is activated to make the two semi-circular electromagnets adsorb into one. After the position is adjusted, the tenon pin 12 is inserted into the slot so that the two semi-circular sleeves are fixed as a whole on the arch rib 41a. For the arch rib 41b that has not yet been welded and fixed, the above operation can be performed on the ground and then hoisted. After the unfixed arch rib 41a and the arch rib fixing sleeve 1 are hoisted to the designated position, the connecting rod bolt fixing device 2 is installed between the two arch rib fixing sleeves 1, so that the temporary connection of the arch rib can be quickly achieved.

[0042] like Figure 2 As shown, the arch rib fixing sleeve 1 mainly includes: a semi-circular sleeve 11, a tenon and mortise pin 12, a rubber anti-slip pad 13, and a lifting handle 14.

[0044] like Figure 4 As shown, the electromagnet adsorption device 3 mainly includes: a motor 31, an annular electromagnet 32a, an electromagnet block 32b, and a motor mounting platform 33. The motor 31 provides electrical energy to the annular electromagnet 32a and the electromagnet block 32b. The annular electromagnet 32a makes the arch rib fixing sleeve 1 fit tightly against the arch rib 4. The electromagnet block 32b makes the two semi-circular sleeves 11 adsorbed to facilitate the installation of the tenon and mortise pins 12. The motor mounting platform 33 provides a stable fixed position for the motor 31.

[0045] The working principle of this utility model is as follows:

[0046] The electromagnet adsorption device 3 is installed on the semi-circular sleeve 11. The semi-circular sleeve 11 is lifted by a crane. The two semi-circular sleeves are fitted to the arch rib 41a and the two semi-circular sleeves 11 by the annular electromagnet 32a and the electromagnet block 32b. Then, the tenon and mortise pin is inserted to complete the assembly of the arch rib fixing sleeve 1.

[0047] For the arch rib 41b that has not yet been welded and fixed, the above steps can be repeated on the ground to install the arch rib fixing sleeve 1;

[0048] The arch rib 41b and the arch rib fixing sleeve 1 are lifted together to a position where the connecting rod 21 can be inserted, and the bolts 23 are tightened to quickly fix the temporary connection between the arch rib 41a and the arch rib 41b.

[0050] (1) The arch rib fixing sleeve is the main part of the device. It consists of a semi-circular sleeve, tenon and mortise pins, rubber anti-slip pads and lifting handles. The lifting handles can realize the portable lifting of the semi-circular sleeves. After the semi-circular sleeves are lifted, they fit against the surface of the arch rib and are attracted by the electromagnet of the cross section. The two semi-circular sleeves are fixed by tenon and mortise pins, making the installation and fixing convenient and quick.

[0051] (2) The connecting rod bolt fixing device is the connecting component of the device, consisting of a connecting rod, a washer and a bolt. The connecting rod passes through the holes of the two arch rib fixing sleeves to realize the positioning of the arch rib. The washer and bolt can fix the relative position of the two arch rib fixing sleeves. The arch rib positioning is convenient and quick, and the connection accuracy of the two arch ribs is high.

[0052] (3) The electromagnet adsorption device provides a stable adsorption force and a portable adsorption function during installation.

The annular electromagnet and the electromagnet block respectively provide the adsorption force on the arch rib and the portable adsorption function during installation. The motor mounting platform provides a position for the motor to be fixed to the arch rib fixing sleeve.
