Technical Field
[0001] The utility model relates to the technical field of replacing bridge beam bottom inspection vehicles, in particular to a disassembly and assembly tool for bridge beam bottom inspection vehicles. Background Art
[0002] The bridge bottom inspection vehicle is a special equipment installed at the bottom of the bridge for daily maintenance. As the construction and operation cycle of the bridge increases, the bridge bottom inspection vehicle will experience aging and failure. Therefore, it is necessary to replace these bridge bottom inspection vehicles. However, in the process of replacing the old bridge inspection vehicles, the traditional construction technology has problems such as high construction cost, long construction period or unsuitability. The main problems are as follows:
[0003] 1. When replacing the bridge bottom inspection vehicle on a cross-river or cross-sea bridge, since the bridge is located on the river or sea surface, the traditional construction technology is used to replace the bridge bottom inspection vehicle, which requires the cooperation of ships for construction. In addition, since it involves sea operations, it is necessary to report and apply to the relevant departments. The construction process is cumbersome and there are many construction coordination units, resulting in high construction costs and uncontrollable construction period.
[0004] 2. The traditional dismantling of bridge beam bottom inspection vehicles and the installation of new inspection vehicles both use a car crane or winch to dismantle and lower and hoist the entire vehicle. However, when the body structure of the old inspection vehicle is damaged or seriously aged, there are serious safety hazards in the overall dismantling and lowering. Therefore, under the premise of ensuring safety, the entire body structure needs to be fully reinforced before lowering the vehicle, which is time-consuming and labor-intensive and seriously increases construction costs.
[0005] 3. When the water level below the inspection vehicle is too shallow or there are many underwater reefs that make it impossible for ships to reach, the traditional inspection vehicle replacement construction process will not meet the construction requirements, and the traditional inspection vehicle replacement construction process has a small scope of application.

[0073] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0074] Example 1
[0075] like Figure 1-Figure 5 As shown, this embodiment provides a disassembly and assembly tool for a bridge beam bottom inspection vehicle, comprising a track system, a sliding system, and a lifting system. The track system comprises a plurality of track connectors 2 and two sliding tracks 3. The two sliding tracks 3 are arranged parallel to each other, with the length direction of the sliding tracks 3 along the transverse direction of the bridge 1, and the ends of the sliding tracks 3 extend out of the side of the bridge 1. The track connectors 2 are connected to the bottom of the bridge 1, and each sliding track 3 is connected to the bridge 1 via a plurality of track connectors 2. The plurality of track connectors 2 are arranged at intervals along the transverse direction of the bridge 1.
[0076] In this embodiment, the bridge 1 is a steel box girder, the track connecting seat 2 is welded to the bottom of the bridge 1, and the sliding track 3 is welded and fixed to the track connecting seat 2.
[0077] like Figure 3As shown, the sliding system includes a sliding bracket 4, a traveling assembly 5, and a manned platform 6; the traveling assembly 5 is mounted on the sliding bracket 4, and the traveling assembly 5 is coupled to the sliding track 3, and the sliding bracket 4 moves on the sliding track 3 via the traveling assembly 5. In this embodiment, the sliding bracket 4 has a U-shaped cross-section, and the sliding bracket 4 surrounds the bridge beam bottom inspection vehicle 8. After removal, the truss segments of the bridge beam bottom inspection vehicle 8 can be lowered onto the sliding bracket 4. Two groups of the traveling assembly 5 are mounted on the top of the sliding bracket 4, and the two groups of the traveling assembly 5 are coupled to two sliding tracks 3, respectively, to ensure the stability of the movement of the sliding bracket 4. The traveling assembly 5 can not only bear the weight of the sliding bracket 4, but also the weight of the truss segments of the bridge beam bottom inspection vehicle 8 placed on the sliding bracket 4 later, allowing the sliding bracket 4 carrying heavy objects to move on the sliding track 3. The walking assembly 5 includes a walking wheel, which is rollingly connected to the sliding track 3. However, it is not limited to the walking wheel. Walking assemblies 5 of other structural forms can also be used, as long as they can drive the sliding bracket 4 to move on the sliding track 3.
[0078] The manned platform 6 is installed on both sides of the sliding bracket 4. In this embodiment, the manned platform 6 is located on both sides of the sliding bracket 4 along the bridge. When working, workers enter the manned platform 6. The manned platform 6 is surrounded by protective fences to provide safety protection for the workers.
[0079] Based on the truss segments of the bridge beam bottom inspection vehicle 8, fixed lifting points are welded to the bottom of the bridge 1. One end of the lifting system is connected to the fixed lifting points, and the other end of the lifting system is used to connect to the truss segments of the bridge beam bottom inspection vehicle 8. The lifting system is used to achieve the lifting and lowering of the truss segments. The lifting system includes a hand chain hoist 7, but is not limited to the hand chain hoist 7. Other lifting equipment capable of lifting and lowering truss segments can also be used.
[0080] When it is necessary to dismantle the old bridge beam bottom inspection vehicle, first use the old bridge beam bottom inspection vehicle as a construction platform, install the track connecting seat 2 at the bottom of the bridge 1, and install the sliding track 3 through the track connecting seat 2; then arrange the sliding bracket 4 on the sliding track 3, and connect the walking component 5 on the top of the sliding bracket 4 with the sliding track 3 to ensure that the sliding bracket 4 can move along the sliding track 3; then weld fixed lifting points at the bottom of the bridge 1 according to the truss segments of the old bridge beam bottom inspection vehicle, the positions of the fixed lifting points correspond to the positions of the truss segments, and install the hand hoist 7 at the fixed lifting points ; Then, the old bridge beam bottom inspection vehicle is dismantled, and the truss segments of the old bridge beam bottom inspection vehicle are connected by the hand hoist 7. Then, the connecting parts between the truss segments are removed, and the truss segments are lowered onto the sliding bracket 4 through the hand hoist 7. The staff operates on the manned platform 6 to move the sliding bracket 4 along the sliding track 3 to the end of the sliding track 3. At this time, the sliding bracket 4 is located on the outside of the bridge 1. The truss segment is lifted to the bridge deck by the lifting equipment 9 such as the car crane on the bridge deck to complete the dismantling of the truss segment. According to the above method, the truss segments of the old bridge beam bottom inspection vehicle are dismantled one by one.
[0081] When a new bridge beam bottom inspection vehicle needs to be installed, the truss segment of the new bridge beam bottom inspection vehicle is lowered onto the sliding bracket 4 through the lifting equipment 9 such as the car crane on the bridge deck, and then the sliding bracket 4 is moved to the installation position to complete the installation of the truss segment. Then, the other truss segments of the new bridge beam bottom inspection vehicle are installed in sequence until the installation of the entire new bridge beam bottom inspection vehicle is completed.
[0082] To save manpower, a drive assembly can be further installed on the sliding bracket 4 and connected to the travel assembly 5. The drive assembly provides driving force for the travel assembly 5, so that the sliding bracket 4 can move along the sliding track 3 under the action of the power. The staff can control the drive assembly on the manned platform 6, thereby saving manual labor and improving work efficiency. The drive assembly can be a drive motor or the like.
[0083] The disassembly and assembly tooling of the bridge beam bottom inspection vehicle of the present invention is installed at the bottom of the bridge 1, and the old bridge beam bottom inspection vehicle is dismantled in sections, and the dismantled truss segments are moved to the outside of the bridge 1 by the sliding bracket 4, and then the truss segments are lifted to the bridge deck by the lifting equipment 9 on the bridge deck, and the dismantling of the truss segments is completed. Compared with the overall dismantling method of the inspection vehicle in the prior art, for the inspection vehicle of a bridge section located on the river or sea surface, the utility model dismantles the inspection vehicle in sections through the disassembly and assembly tooling of the bridge beam bottom inspection vehicle, without the need to cooperate with ship construction and without the need to make relevant reporting and filing applications, thus simplifying the construction process, avoiding coordination among multiple units, reducing the construction process and on-site coordination and cooperation work, reducing construction costs, and shortening the construction period. Moreover, the present invention The existing method of dismantling the inspection vehicle as a whole is only applicable to the case where the overall structure of the old bridge beam bottom inspection vehicle is under normal stress. If there are problems with the body structure or it is severely aged, it needs to be reinforced as a whole before the dismantling work can be carried out. However, the present invention can not only meet the requirements of dismantling the inspection vehicle with a normal body structure, but also can implement it after temporary reinforcement of the part when there are problems with the body structure or the body is severely aged, thereby reducing the reinforcement workload, lowering the construction cost, and shortening the construction period. When the water level below the location of the inspection vehicle is too shallow or there are many underwater reefs that make it impossible for ships to reach, the traditional inspection vehicle replacement construction process will not be able to meet the construction requirements. However, the present invention does not require the cooperation of ships in construction, is not affected by the water environment, and has a wider range of applications. After the present invention completes the dismantling of the old bridge beam bottom inspection vehicle through the bridge beam bottom inspection vehicle disassembly and assembly tooling, the new bridge beam bottom inspection vehicle can also be installed in sections through the tooling to complete the replacement of the bridge beam bottom inspection vehicle.

[0086] S2: Arrange the sliding bracket 4 on the sliding track 3, and connect the walking assembly 5 on the sliding bracket 4 to the sliding track 3 so that the sliding bracket 4 can move along the sliding track 3;
[0087] S3: Weld fixed lifting points at the bottom of the bridge 1 according to the truss segments of the inspection vehicle at the bottom of the old bridge beam, and install a lifting system at the fixed lifting points;
[0088] S4: Dismantle the old bridge beam bottom inspection vehicle: use the lifting system to connect the truss segments of the old bridge beam bottom inspection vehicle, then remove the connectors between the truss segments, and lower the connected truss segments onto the sliding bracket 4 through the lifting system. The staff pushes the sliding track 3 in the opposite direction on the manned platform 6, and the sliding bracket 4 is moved to the end of the bridge along the sliding track 3 by the reaction force, or the sliding bracket 4 is driven by the driving component to move to the end of the bridge along the sliding track 3. At this time, the sliding bracket 4 is located on the outside of the bridge 1, and the truss segment is lifted to the bridge deck by the lifting device 9 on the bridge deck to complete the dismantling of the truss segment. According to the above method, the truss segments of the old bridge beam bottom inspection vehicle are dismantled one by one; in order to improve the dismantling efficiency, the dismantling operation can be carried out on both sides of the bridge 1 simultaneously or successively;
[0089] S5: Installing the new bridge beam bottom inspection vehicle: lowering the truss segment of the new bridge beam bottom inspection vehicle onto the sliding bracket 4 through the lifting equipment 9 on the bridge deck, and then moving the sliding bracket 4 to the installation position to complete the installation of the truss segment, and then installing the other truss segments of the new bridge beam bottom inspection vehicle in sequence until the installation of the entire new bridge beam bottom inspection vehicle is completed; during installation, the installation operation can also be carried out simultaneously or successively on both sides of the bridge 1.
[0090] like Figures 6-10 As shown, starting from the left side of the bridge 1, first remove the upper and lower passages at the left end of the old bridge beam bottom inspection vehicle, and directly lift it to the bridge deck through the lifting equipment 9 on the bridge deck; then remove the left end truss section, move it to the outside of the bridge 1 through the sliding bracket 4, and then use the lifting equipment 9 on the bridge deck to lift it to the bridge deck; then remove the left drive and gantry, and the middle truss section; then remove the right side structure of the old bridge beam bottom inspection vehicle on the right side of the bridge 1 in the same way as mentioned above, and complete the dismantling of the old bridge beam bottom inspection vehicle.
[0091] like Figure 11-14 As shown, starting from the left side of the bridge 1, the middle truss section of the new bridge beam bottom inspection vehicle is first installed, and then the left drive and gantry are installed, and then the middle truss section, the left end truss section, and the left end upper and lower channels are installed; then the right side structure of the new bridge beam bottom inspection vehicle is installed on the right side of the bridge 1 in accordance with the above method to complete the installation of the new bridge beam bottom inspection vehicle.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations.
