[0002] Steel box arch bridge manufacturing technology is a crucial aspect of bridge engineering, particularly the quality of the junction between the arch rib and the steel box girder (referred to as the arch-beam junction). This junction is manufactured separately from the steel box girder, then the entire arch beam is pressed against the top surface of the steel box girder before being welded together. The arch rib is internally provided with multiple partitions and webs, creating a very narrow working space that is inaccessible to workers, requiring the use of a small welding robot to complete the welding operation. The partitions of the arch rib are provided with operating holes, and the small welding robot is manually placed through the operating holes into the corresponding narrow space for welding. This requires repeated manual movement and relocation to complete the welding operation. Furthermore, the narrow space on the arch rib farthest from the top opening is too far away and too small for the small welding robot to be manually inserted, making welding impossible there.

[0053] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0054] See Figure 1 The present invention provides a split-type multifunctional internal working device for an arch-beam joint and a method for using the device. The device is used to automatically perform operations such as welding, grinding, cleaning, and spraying on the arch-beam joint, eliminating the need for personnel to enter the arch beam interior, thus saving labor and improving work efficiency. The present invention's multifunctional internal working device for an arch-beam joint and its method for using the device are described below with reference to the accompanying drawings.

[0055] See Figure 1 , showing a schematic diagram of the three-dimensional structure of the multifunctional operating equipment inside the split arch-beam combination section of the present invention. Figure 12, showing the structural diagram of the multifunctional working equipment in the split arch-beam joint section of the present invention entering into a narrow space. Figure 1 and Figure 12 , the multifunctional operating equipment inside the split arch-beam combination section of the present invention is explained.

[0056] like Figure 1 and Figure 12 As shown, the multifunctional operation equipment inside the split arch beam joint section of the present invention is used to realize the welding, grinding, cleaning or spraying operations of the arch rib 10 and the steel box beam 30 in a narrow space. The arch rib 10 includes a top plate 11, a bottom plate 12, an upper web 13 and a lower web 14 connected on both sides of the top plate 11 and the bottom plate 12, a middle web 15 supported between the top plate 11 and the bottom plate 12 and located between the upper web 13 and the lower web 14, and a plurality of partitions 16 vertically connected to the middle web 15. The partitions 16 are arranged on the inner sides of the top plate 11, the bottom plate 12, the upper web 13 and the lower web 14. The sizes of the partitions 16 are different. An operation hole is provided in the middle of the partition 16. The connections between the top plate 11, the bottom plate 12, the upper web 13, the lower web 14, the middle web 15 and the partitions 16 are fixed by welding. The size of 12 is smaller than that of the top plate 11, and one side of the upper web 13 and the lower web 14 is aligned with one side of the bottom plate 12 and the top plate 11, and the other side is inclined so as to be in contact with the surface of the steel box girder 30 together with the corresponding side of each partition 16. In this way, a narrow space is formed between the two adjacent partitions 16 and the corresponding upper web 13 and lower web 14, middle web 15 and the surface of the steel box girder 30. The positions where the partition 16, upper web 13, lower web 14, middle web 15, bottom plate 12 and top plate 11 are in contact with the steel box girder 30 need to be welded, polished, cleaned and sprayed with the steel box girder 30. The multifunctional operating equipment inside the split arch beam joint section of the present invention is used to weld, polish, clean and spray the above-mentioned positions to achieve the connection between the arch rib 10 and the steel box girder 30.

[0057] The multifunctional working equipment inside the split arch-beam joint section of the present invention comprises a walking crawler 21, a rotating disk 23 and a serpentine transfer mechanism 25. Figure 2 and Figure 3As shown, the walking track 21 is provided with multiple pairs of track wheels 211. The relative positions of two adjacent pairs of track wheels 211 can be adjusted in the vertical direction to achieve obstacle crossing, and the relative positions of two adjacent pairs of track wheels 211 can also be adjusted in the horizontal direction to achieve turning. The walking track 21 achieves its walking function through the rotation of the multiple pairs of track wheels 211. The relative positions of the two adjacent pairs of track wheels 211 are adjusted in the vertical direction, which enables the height adjustment of the two adjacent pairs of track wheels 211. In this way, the walking track 21 can be bent upward or downward, thereby crawling along obstacles and achieving crossing obstacles. The relative positions of the two adjacent pairs of track wheels 211 are adjusted in the horizontal direction, which enables the two adjacent pairs of track wheels 211 to swing left and right in the horizontal plane. In this way, the walking track 211 can achieve left and right turning adjustment. The walking track 211 has a flexible bending adjustment function, which enables it to smoothly crawl into narrow spaces and also smoothly walk in narrow spaces. The rotating disk 23 is rotatably supported on the running track 21 and can be rotated and adjusted relative to the running track 211. One end of the serpentine transfer mechanism 25 is connected to the rotating disk 23, and the other end of the serpentine transfer mechanism 25 is connected to the working head 27. The serpentine transfer mechanism 25 can be wound around the rotating disk 23 and then extended by the rotation of the rotating disk 23. The serpentine transfer mechanism 25 can be bent and rotated to carry the working head 27 to the corresponding connection position of the arch rib 10 and the steel box girder 30 to complete welding, grinding, cleaning or spraying operations.

[0058] When the equipment of the present invention is moving, the serpentine transfer mechanism 25 can be rolled up by the rotation of the rotating disk 23, so that the serpentine transfer mechanism 25 is wound on the rotating disk 23. In this way, the equipment is small in size and can easily enter a narrow working space. When it moves close to the working position, the rotating disk 23 can release the serpentine transfer mechanism 25 by rotating, and then the serpentine transfer mechanism 25 can bring the working head 27 to the working position through its own bending and rotation adjustment, and then perform welding, grinding, cleaning or spraying operations.

[0059] The equipment of the present invention can not only realize welding operations, but also realize grinding operations, cleaning operations and spraying operations. The working head 27 can be replaced accordingly according to the actual working functions required. The equipment of the present invention is equipped with a working head for welding, a working head for grinding, a working head for cleaning and a working head for spraying. When performing the corresponding welding operation, the welding working head is connected to the serpentine transfer mechanism 25. When performing the corresponding grinding operation, the grinding working head is connected to the serpentine transfer mechanism 25. When performing the corresponding cleaning operation, the cleaning working head is connected to the serpentine transfer mechanism 25. When performing the corresponding spraying operation, the spraying working head is connected to the serpentine transfer mechanism 25.

The first rotating shaft 215 is arranged parallel to the wheel axle 212 . The setting height of the first rotating shaft 215 can be higher than the wheel axle 212 or lower than the wheel axle 212 .

[0062] The first connecting plate 213 and the second connecting plate 214 can be rotated and adjusted around the first rotating shaft 215, so that the part of the walking track 21 between the two adjacent pairs of track wheels 211 can be bent upward or downward, so that the walking track 21 can climb over the corresponding obstacles and realize the obstacle crossing function.

[0063] Furthermore, the first connecting plate 213 and the second connecting plate 214 each include a first plate body and a second plate body that are rotatably connected, and the axis of relative rotation adjustment of the first plate body and the second plate body is perpendicular to the setting direction of the first plate body and the second plate body.

[0064] The first and second plate portions are hingedly connected via a second rotational axis 216. The first and second plate portions, along with the second rotational axis 216, are all located within the same vertical plane, with the second rotational axis 216 being perpendicular to the orientation of the first and second plate portions. The first and second plate portions are arranged at an angle, and the second rotational axis 216 is also arranged at an angle. By rotating the first and second plate portions relative to the second rotational axis 216, the walking track 21 can achieve turning adjustment.

[0065] Furthermore, a plurality of electromagnets 217 are provided on the walking track 21, and the electromagnets 217 can allow the walking track 21 to be adsorbed on the corresponding parts of the arch rib 10 and the steel box girder 30, thereby improving the walking safety of the walking track 21 and avoiding the phenomenon of falling.

[0066] Furthermore, power gears are provided at the front and rear ends of the traveling crawler 21, and the power gears mesh with the crawler tracks of the traveling crawler 21. A power motor is provided at the front or rear end of the traveling crawler 21, and the power motor can drive the power gears to rotate through gears, and then the rotation of the power gears will drive the crawler tracks to rotate, and the multiple pairs of track wheels provided inside the crawler tracks will also rotate, thereby realizing the travel of the traveling crawler 21. When the traveling crawler 21 turns, the turning motor drives the power gears to turn, so that the connection between the crawler tracks and the track wheels will cooperate to adjust the turn.

[0067] Furthermore, mounting brackets are provided on the power gears at the front and rear ends of the walking track 21, and detectors are provided on the mounting brackets corresponding to the front and rear of the walking track 21, which are used to detect obstacles in front and rear of the walking track 21 and form detection information.

[0068] In a specific embodiment of the present invention, Figure 4 and Figure 5 As shown, the serpentine transfer mechanism 25 includes a plurality of adjustment units 251 connected in sequence. Two adjacent adjustment units 251 can be adjusted to swing horizontally and vertically relative to each other. A plurality of running wheels 2511 are provided on the periphery of each adjustment unit 251.

[0069] The serpentine transport mechanism 25 achieves flexible bending between the adjustment units 251 through relative swing adjustment, including horizontal and vertical swing adjustment, thereby enabling the work head to be moved to the desired working position. Multiple running wheels 2511 are spaced apart around the periphery of the adjustment units 251. The rolling motion of the running wheels 2511 facilitates the movement and adjustment of the serpentine transport mechanism 25.

A welding operation head, such as a welding gun, is mounted on the mounting seat 261, and the equipment is placed on the partition 16 corresponding to the inside of the arch rib 10. At this time, the serpentine transfer mechanism 25 is wound around the rotating disk 23, and the walking track 21 is adsorbed on the partition 16 by the provided electromagnet 217. The walking track 21 is started, and the walking track 21 is allowed to carry the equipment through the operation hole on the partition 16 into the narrow space. The walking track 21 passes over the partition 16 and then contacts the surface of the steel box girder 30, combined with Figures 15 to 17 As shown, the walking track 21 can move on the surface of the steel box girder 30 in a narrow space, and can bring the working head to the corresponding connection position. After the equipment enters the narrow space, the serpentine transfer mechanism 25 gradually unfolds, and the rotating disk 23 rotates synchronously. After the serpentine transfer mechanism 25 is stretched out, it can crawl on the surface of the steel box girder 30, and cooperate with the walking of the walking track 21 to bring the working head, which is now the welding gun, to the welding position. The welding gun welds the welding position, and then the serpentine transfer mechanism 25 continues to move and carries the welding gun to weld the next welding position until all the welding positions in the narrow space are welded. After completing the welding operation, the serpentine transfer mechanism 25 is retracted on the rotating disk 23, and the walking track 21 returns with the equipment, and then enters the next narrow space to perform welding operations until the positions where the arch rib 10 contacts the steel box girder 30 are welded.

[0087] The welding gun on the equipment is then replaced with a grinding head, such as a grinding disc or a laser grinding mechanism. The equipment enters the narrow space using the above method, and then grinds the weld with the grinding head. After grinding is completed, the equipment returns. The grinding head is then replaced with a cleaning head to clean the powder and residue removed by grinding. The cleaning head, such as a rotatable brush, is also equipped with a dust collection mechanism that can absorb and collect powder and residue. After cleaning, the equipment returns. The cleaning head is replaced with a spraying head, such as a nozzle and a protective paint supply mechanism (protective paint storage barrel, delivery pipeline, and pump). The spraying head sprays protective paint on the surface of the weld. In this way, the equipment of the present invention can enter the interior of the arch rib and complete operations such as welding, grinding, cleaning, and spraying without the need for human intervention, which can save labor and improve work efficiency.

[0088] The present invention also provides a method for using the multifunctional operating equipment inside the split arch-beam combination section, and the method for using is described below.

[0089] The method of using the present invention comprises the following steps:

[0090] After the arch ribs and steel box beams are placed, start the crawler tracks and allow the equipment to crawl into the narrow space enclosed by the arch ribs and steel box beams;

[0091] The rotating disk is rotated to extend the serpentine transfer mechanism, and the serpentine transfer mechanism is started to bend and crawl, so that the working head reaches the connection position corresponding to the arch rib and the steel box girder;

[0092] The welding, grinding, cleaning or spraying of arch ribs and steel box girders are completed through the operation head;

[0093] By utilizing the movement and rotation adjustment of the walking tracks, rotating disk and serpentine transfer mechanism, the working head is adjusted to the next connection position to perform the corresponding operation. After the operation is completed, the equipment is returned by the walking tracks.

[0094] Furthermore, the operation head can perform welding, grinding, cleaning and spraying operations on the connection position between the arch rib and the steel box girder, and the corresponding operation can be completed by replacing the corresponding operation head.

[0095] The present invention has been described in detail above with reference to the embodiments of the accompanying drawings. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the appended claims.
