Abstract
Description
Technical Field
[0001] This invention relates to the field of municipal bridge engineering technology, and in particular to a bridge repair suspension device for municipal bridge engineering. Background Technology
[0002] A bridge, generally speaking, refers to a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also been extended to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient. A bridge typically consists of a superstructure, substructure, supports, and ancillary structures. Various public infrastructure projects supporting urban life fall under the category of municipal engineering. Pedestrian overpasses, also known as pedestrian interchanges, are generally built in areas with high traffic volume and dense pedestrian flow, or at intersections, squares, and railways. Pedestrian overpasses allow only pedestrians to pass, avoiding conflicts when vehicular and pedestrian traffic intersect at the same level, ensuring safe crossing, increasing vehicle speed, and reducing traffic accidents; they are a type of municipal bridge. Pedestrian overpasses are prone to cracks at their base during long-term use. Therefore, a common practice is to install lifts at the bottom of the bridge for maintenance and repairs. However, in practice, the installation of these lifts has frequently caused traffic congestion and severe disruptions to driving. Therefore, we propose a suspension device for bridge repair in municipal bridge engineering. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a bridge repair suspension device for municipal bridge engineering to solve the technical problem that the operation of the current elevator used for pedestrian overpass repair work affects road traffic.
[0004] To achieve the objectives of this invention, the technical solution adopted is as follows: A bridge repair suspension device for municipal bridge engineering is designed, comprising a suspended platform mechanism, a main connecting shaft, a combined mechanism, a traveling wheel mechanism, and a safety structure; the main connecting shaft is symmetrically arranged on both sides of the suspended platform mechanism via bolts A; the combined mechanism is arranged at the end of the main connecting shaft via bolts B; the traveling wheel mechanism is arranged on the combined mechanism via bolts C; and the safety structure is arranged on the main connecting shaft via bolts D; wherein the suspended platform mechanism, main connecting shaft, combined mechanism, and traveling wheel mechanism form a traveling suspended platform structure; wherein the safety structure includes a connecting mechanism and a limiting drive block; the connecting mechanism is arranged on the main connecting shaft via bolts D; and the limiting drive block is arranged on the connecting mechanism. This invention uses bolted assembly to adjust the suspended basket mechanism, main connecting shaft, combination mechanism, and traveling wheel motor for assembly with the pedestrian overpass. It also utilizes the traveling wheel motor and safety structure to drive directional linear movement. Compared with elevators, this bridge repair suspension device effectively avoids blocking the driving section at the lower end of the pedestrian overpass during repair operations, thereby reducing road congestion and traffic jams and alleviating traffic pressure.
[0005] Preferably, the suspended platform mechanism includes a suspended platform body and plug-in sleeves; the suspended platform body is arranged below the traveling wheel; and four plug-in sleeves are arranged on both sides of the suspended platform body.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

The safety structure 5 is arranged on the main connecting shaft 2 via bolts D. The suspended platform mechanism 1, the main connecting shaft 2, the combined mechanism 3, and the traveling wheel motor 4 constitute a traveling suspended platform suspension structure. The safety structure 5 includes a connecting mechanism 6 and a limit drive block 7. The connecting mechanism 6 is arranged on the main connecting shaft 2 via bolts D. The limit drive block 7 is arranged on the connecting mechanism 6. This invention uses bolt assembly to adjust the suspended basket mechanism 1, main connecting shaft 2, combination mechanism 3, and traveling wheel 4 to adapt to the pedestrian overpass for assembly. It also utilizes the traveling wheel 4 and safety structure 5 to drive directional linear movement. Compared with elevators, this bridge repair suspension device effectively avoids the interruption of the driving section at the lower end of the pedestrian overpass during repair operations, thereby reducing road congestion and traffic jams and alleviating traffic pressure.
[0030] Specifically, the suspended platform mechanism 1 includes a suspended platform body 101 and four plug-in sleeves 102; the suspended platform body 101 is arranged below the traveling wheel 4; and four plug-in sleeves 102 are arranged on both sides of the suspended platform body 101.
[0031] Furthermore, the main connecting shaft 2 is movably connected to the insertion sleeve 102; and the main connecting shaft 2 is threadedly connected to the insertion sleeve 102 via bolt A. This invention allows for the telescopic adjustment of bolt A and the main connecting shaft 2 and insertion sleeve 102 to adapt to the installation requirements of the bridge repair suspension device in this municipal bridge project.
[0032] Furthermore, the assembly mechanism 3 includes a first mounting base 301, a crossbeam 302, a second mounting base 303, and an extension shaft 304. The first mounting base 301 is screwed to the end of the main connecting shaft 2; the crossbeam 302 is screwed to the first mounting base 301; the second mounting base 303 is screwed to the other side of the crossbeam 302; and the extension shaft 304 is screwed to the second mounting base 303. The traveling wheel 4 is mounted on the extension shaft 304 via a mounting bracket. This invention, through the bolted connection of the first mounting base 301, the crossbeam 302, the second mounting base 303, and the extension shaft 304, allows for free assembly of the bridge repair suspension device for municipal bridge engineering, meeting the temporary lifting requirements of the elevator and adapting to the actual installation needs of pedestrian overpasses of different thicknesses.
[0033] It is worth noting that the connecting mechanism 6 includes a combined mounting base 601 and a motor 603; the internal gap of the combined mounting base 601 forms a drive engagement cavity; several drive gears 602 are arranged inside the drive engagement cavity via a drive shaft; the motor 603 is arranged at the end of the drive shaft and connected to the combined mounting base 601; wherein, the combined mounting base 601 has an annular connecting groove with a cross-section in the shape of a cross on the side near the limiting drive block 7. As shown in the accompanying drawings of this invention, the limiting drive block 7 of the bridge repair suspension device of this municipal bridge project is fitted onto one of the transverse handrails on both sides of the pedestrian overpass during the movement of the device; this improves the safety of the actual use of the bridge repair suspension device of this municipal bridge project and provides an auxiliary safety connection measure for the bridge repair suspension device in the event of detachment or other safety issues.
[0034] It is worth noting that the limiting drive block 7 is composed of a spiral block 701 and several combined meshing teeth 702; wherein, the combined meshing teeth 702 are arranged in the annular connecting groove; and, the combined meshing teeth 702 are matched and meshed with the drive gear 602; and, the annular connecting groove is movably connected to the combined meshing teeth 702. This invention uses a motor 603 to drive several drive gears 602 to rotate synchronously, so that the limiting drive block 7 rotates within the annular connecting groove. Utilizing the open shape of the spiral block 701, when the spiral block 701 contacts the vertical support rod connected to the horizontal handrail, it can effectively be misaligned, allowing the safety structure 5 to be misaligned with the support rod, thereby avoiding the problem of frequent installation, disassembly, and use of the safety structure 5.
[0035] It is worth noting that the combined mounting base 601 has an arc-shaped surface on the side near the limiting drive block 7; the arc-shaped surface and the limiting drive block 7 are located at the same center, and the arc-shaped surface is adapted to the outer diameter of the spiral block 701; two stress-connecting protrusions are symmetrically arranged on both sides of the arc-shaped surface; and the line connecting the two stress-connecting protrusions is located between the inner and outer diameters of the spiral block 701. This invention, by having an arc-shaped surface and stress-connecting protrusions in the combined mounting base 601, improves the connection strength between the combined mounting base 601 and the limiting drive block 7, effectively improving the stability of the safety structure 5 in actual use.
[0036] Working principle: First, a lift supports the suspended platform mechanism 1 and the main connecting shaft 2 at the lower end of the pedestrian overpass. Then, the safety structure 5 is manually adjusted and rotated onto the crossbar of the pedestrian overpass railing. It is then installed and connected to the main connecting shaft 2 using bolts. Next, the first mounting base 301, the crossbar 302, the second mounting base 303, and the extension shaft 304 are installed sequentially using bolts. Finally, the traveling wheel mechanism 4 is installed with bolts, ensuring its bottom contacts the top surface of the pedestrian overpass. Simultaneously, the crossbar 302 is higher than the pedestrian overpass railing. During use, the traveling wheel mechanism 4 drives the bridge repair suspension device to move linearly. The bottom of the pedestrian overpass was painted and cracks were repaired. Limiting drive blocks 7 were used to connect the two sides of the guardrail to improve the safety of the bridge repair suspension device. At the same time, a motor 603 drove several drive gears 602 to rotate synchronously, so that the limiting drive blocks 7 could rotate within the annular connecting groove. The spiral block 701 had an open shape, so that when the spiral block 701 came into contact with the vertical support rod connected to the horizontal handrail, it could be effectively misaligned, so that the safety structure 5 could be misaligned with the support rod, and continuous safety protection could be carried out without repeated installation and disassembly.

Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
