Description

Technical Field

[0001] This application relates to the field of bridge equipment technology, and in particular to a mobile railway suspension platform. Background Technology

[0002] For railway bridges spanning valleys or rivers, the inspection and maintenance of substructure components are often difficult due to natural conditions. This is especially true for lines with high traffic requirements and strict time limits for maintenance windows. Based on these factors, the construction platform for substructure maintenance often requires large-tonnage cranes, full-span scaffolding, or boat cranes. Such platforms have long preparation times, demanding site conditions, low flexibility, and high costs. From the perspectives of construction efficiency, cost, and safety, these equipment or platforms all have certain limitations.

[0003] In related technologies, such as the bridge and box-shaped bridge inspection device with flange plates authorized by CN210529487U, the entire device is moved along the bridge by the travel mechanism on the bridge deck. The support mechanism and the suspension mechanism work together to achieve a firm suspension with the bottom working platform. The up and down mechanism allows the inspection personnel to go from the bridge deck to the bottom working platform to work. The closed loop can make the entire device more stable and safer, and the bottom working platform can accommodate more people to work at the same time, thus improving efficiency.

[0004] However, its bridge deck traveling mechanism spans the bridge deck, occupying bridge deck space and affecting vehicle traffic. Therefore, it is necessary to study and improve the above structure to provide a mobile railway suspension platform, aiming to achieve a more practical purpose. Summary of the Invention

[0005] To address the shortcomings or deficiencies of the aforementioned background technology, this application provides a mobile railway suspension platform. The platform does not occupy the space of the bridge deck rails and does not affect the passage of trains on the bridge deck. It has the advantages of small bridge deck footprint, convenient movement, and high flexibility, and is suitable for locations with construction needs on the underside of railway bridges or similar working conditions.

[0006] This application provides a mobile railway sling platform, including: Side platform, which is located outside the side of the bridge and forms a longitudinally extending gap with the side of the bridge; A traveling mechanism located on top of the bridge and traveling between the bridge and the side platform; A suspended platform is located below the bridge and connected to the traveling mechanism via a suspension mechanism that passes through the gap.

[0007] In some embodiments, both the side platform and the bridge are equipped with traveling rails, and the traveling mechanism includes multiple sets of triangular frames spaced apart along the traveling rails, as well as rollers mounted on the triangular frames and adapted to the traveling rails.

[0008] In some embodiments, the triangular frame includes two triangular frames arranged side by side and a crossbar connecting the two triangular frames together, with at least two of the rollers mounted on the triangular frames.

[0009] In some embodiments, the traveling mechanism further includes a connecting rod that connects multiple sets of the triangular frames together, the connecting rod being detachably installed from the triangular frames.

[0010] In some embodiments, the suspension mechanism includes a turnbuckle connected to the triangular frame and a suspension rope connecting the turnbuckle and the suspension platform.

[0011] In some embodiments, the upper end of the turnbuckle is connected to the triangular frame via a hanging ring, and the end of the suspension rope away from the turnbuckle is connected to a buckle.

[0012] In some embodiments, the end of the suspended platform extends below the side platform, and a ladder is detachably installed between the side platform and the suspended platform.

[0013] In some embodiments, a suspension rail extending longitudinally along the bottom surface of the bridge is installed, and a suspension device that is slidably adapted to the suspension rail is installed on the suspended platform.

[0014] In some embodiments, the suspension component includes a fixed rod mounted on the suspended platform, and an upper steel pipe and a lower steel pipe mounted on the fixed rod and slidably connected to the suspension rail.

[0015] In some embodiments, the suspended platform includes multiple sets of transverse trusses spaced apart, and longitudinal trusses connecting the multiple sets of transverse trusses together, with multiple sets of scaffold boards laid on the transverse trusses.

[0016] The beneficial effects of the technical solution provided in this application include: This application provides a mobile railway suspension platform, including a side platform located outside the side of a bridge and forming a longitudinally extending gap with the side of the bridge; a traveling mechanism located on top of the bridge and traveling between the bridge and the side platform; and a suspended platform located below the bridge and connected to the traveling mechanism via a suspension mechanism, the suspension mechanism passing through the gap.

[0017] Because the traveling mechanism is arranged on both sides of the bridge in the transverse direction, it does not occupy the space of the railway tracks on the bridge deck. Therefore, it does not affect the passage of trains on the bridge deck. Moreover, the traveling mechanism spans the gap in the longitudinal direction of the bridge formed by the bridge and the side platform, and is supported on the bridge and the side platform. It can travel on the bridge and the side platform. The suspension mechanism drives the suspended platform below to move along the longitudinal direction of the bridge. Construction personnel can work on the suspended platform. Therefore, it has the advantages of small bridge deck footprint, convenient travel, and high flexibility. It is suitable for locations with construction needs on the underside of railway bridges or similar working conditions. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] To address the shortcomings or deficiencies of the aforementioned background technology, this application provides a mobile railway suspension platform. The platform does not occupy the space of the bridge deck rails and does not affect the passage of trains on the bridge deck. It has the advantages of small bridge deck footprint, convenient movement, and high flexibility, and is suitable for locations with construction needs on the underside of railway bridges or similar working conditions.

[0023] See Figures 1 to 12 As shown, this application embodiment provides a mobile railway sling platform, including: Side platform, which is located outside the side of the bridge and forms a gap with the side of the bridge extending longitudinally; The traveling mechanism is located on top of the bridge and travels on the bridge and side platforms; A suspended platform is located below the bridge and connected to the traveling mechanism via a suspension mechanism 2, which passes through a gap.

[0024] The traveling mechanism of the mobile railway suspension platform in this application embodiment is arranged on both sides of the bridge in the transverse direction, without occupying the space of the bridge deck rails, so it does not affect the passage of trains on the bridge deck. Moreover, the traveling mechanism spans the gap in the longitudinal direction formed by the bridge and the side platform, and is supported on the bridge and the side platform, so it can travel on the bridge and the side platform.

[0025] Furthermore, the suspension mechanism 2 can drive the lower suspension platform to move along the longitudinal direction of the bridge, allowing construction personnel to work on the suspension platform. Therefore, it has the advantages of a small bridge deck footprint, convenient movement, and high flexibility, and is suitable for locations with construction needs on the lower surface of railway bridges or similar working conditions.

[0026] For example, in this instance, the mobile railway suspension platform is applicable to the lower surface of a railway bridge. The railway bridge has a beam with rails installed on its top surface and side platforms arranged on both sides of the beam. Both the beam and the side platforms are supported by a lower crossbeam, and the beam and the side platforms form a gap extending longitudinally along the bridge direction, which can be suspended by a suspension mechanism 2.

[0027] For example, the suspension mechanism 2 can be multiple sets of ropes connecting the traveling mechanism and the suspended platform. The ropes extend through the gaps in the longitudinal direction of the bridge, meaning that the ropes can be stably and vertically stressed. When the suspended platform travels, it can be pushed forward manually or pulled by machinery. When the lower crossbeam blocks the passage of the ropes, the ropes can be untied one by one, that is, only one place is untied at a time. After passing the lower crossbeam, the suspension rope 24 is fixed again until all the ropes have passed, so that the suspended platform can cross the crossbeam obstruction. It has the advantages of convenient travel and good continuity.

[0028] In some alternative embodiments: see Figures 1 to 12 As shown, this application embodiment provides a mobile railway suspension platform. The mobile railway suspension platform is equipped with running rails 4 on both the side platforms and the bridge. The running mechanism includes multiple sets of triangular frames 1 arranged at intervals along the running rails 4, and rollers 3 installed on the triangular frames 1 and adapted to the running rails 4.

[0029] In this embodiment, parallel extending travel rails 4 are installed on the side platform and bridge. Multiple sets of triangular frames 1 travel on the travel rails 4 via rollers 3 installed on them. Each set of triangular frames 1 is connected to the suspended platform through a suspension mechanism 2, and the suspended platform is stably suspended through multi-point suspension.

[0030] For example, the running track 4 includes multiple sections of channel steel 41 spliced ​​together in sequence. A connecting plate 42 is connected between two adjacent sections of channel steel 41. The connecting plate 42 is connected to the channel steel 41 by bolts 43. The channel steel 41 can be fixed to the side platform or bridge by fastening with fasteners.

[0031] In some alternative embodiments: see Figures 1 to 12 As shown, this application embodiment provides a mobile railway sling platform. The triangular frame 1 of the mobile railway sling platform includes two triangular frames arranged side by side, and a crossbar 11 connecting the two triangular frames together. At least two rollers 3 are installed on the triangular frames.

[0032] The triangular frame 1 of this application embodiment is welded together from two triangular frames and three crossbars 11. Specifically, the triangular frames are welded together from angle steel 13 and two round diagonal bars 12. The ends of the three crossbars 11 are welded and fixed to the three ends of the triangular frames respectively, thereby forming a stable frame structure. The rollers 3 are installed on the angle steel 13.

[0033] For example, two rollers 3 are installed on the angle steel 13. The rollers 3 include a top plate 31 and two side plates 32 welded to the top plate 31. The two side plates 32 are rotatably connected to the wheel 34 through a pivot 33. The top plate 31 is rotatably connected to the angle steel 13 through a vertical axis.

[0034] In some alternative embodiments: see Figures 1 to 12 As shown, this application embodiment provides a mobile railway suspending platform. The traveling mechanism of the mobile railway suspending platform also includes a connecting rod 14 that connects multiple sets of triangular frames 1 together. The connecting rod 14 and the triangular frames 1 can be detachably installed.

[0035] The traveling mechanism in this embodiment of the application also includes a connecting rod 14, which can connect multiple sets of triangular frames 1 together, thereby improving the stability of the travel. When it is not necessary to constrain multiple sets of triangular frames 1, the connecting rod 14 can also be disassembled.

[0036] For example, the number of triangular frames 1 on one side is not less than four sets. The four sets of triangular frames 1 are respectively connected and fixed to the connecting rod 14 through the first fastener 15. The triangular frames 1 on both sides move synchronously and at a uniform speed, and the moving speed should not be too fast.

[0037] When the travel path encounters an arc section, the specifications of the channel steel 41 should be changed to adapt to the travel line shape. The wheels 34 of the roller 3 travel inside the channel steel 41. When the travel path encounters an arc section, the triangular frame 1 should be gradually detached from the connecting rod 14 and fixed to the connecting rod 14 one by one after the line shape is restored.

[0038] In some alternative embodiments: see Figures 1 to 12 As shown, this application embodiment provides a mobile railway suspension platform. The suspension mechanism 2 of the mobile railway suspension platform includes a turnbuckle 22 connected to a triangular frame 1, and a suspension rope 24 connecting the turnbuckle 22 and the suspension platform.

[0039] The suspension mechanism 2 in this embodiment includes turnbuckles 22 and suspension ropes 24. The turnbuckles 22 are connected to the triangular frame 1, and the suspension ropes 24 connect the turnbuckles 22 and the suspension platform. Specifically, each triangular frame 1 is connected to a turnbuckle 22 and a suspension rope 24, thereby achieving multi-point suspension of the suspension platform. In addition, the height of the suspension platform can be adjusted by adjusting the length of the suspension ropes 24 and the turnbuckles 22 to adapt to construction.

[0040] In some alternative embodiments: see Figures 1 to 12 As shown, this application embodiment provides a mobile railway suspension platform. The upper end of the turnbuckle 22 of the mobile railway suspension platform is connected to the triangular frame 1 through the hanging ring 21, and the end of the suspension rope 24 away from the turnbuckle 22 is connected to the buckle 25.

[0041] In this embodiment, the upper end of the turnbuckle 22 is connected to the triangular frame 1 via a hanging ring 21. The end of the suspension rope 24 away from the turnbuckle 22 is connected to a buckle 25. For example, the two ends of the suspension rope 24 pass through the hanging hole at the lower end of the turnbuckle 22 and are fixed at both ends by rope clips 23, so that the suspension rope 24 forms a double strand arrangement on the turnbuckle 22. The suspension rope 24 wraps around the pole section of the suspended platform once and then hooks back into the buckle 25, thereby realizing the connection between the suspension rope 24 and the suspended platform.

[0042] In some alternative embodiments: see Figures 1 to 12 As shown, this application embodiment provides a mobile railway suspension platform, the end of which extends to below the side platform, and a ladder 5 is detachably installed between the side platform and the suspension platform.

[0043] In this embodiment of the application, the end of the suspended platform extends below the side platform. A ladder 5 is installed between the side platform and the suspended platform. The ladder 5 includes two side bars 52 arranged in parallel and multiple step bars 51 fixedly connected to the two side bars 52. The two ends of the ladder 5 are detachably connected to the side platform and the suspended platform, respectively. When the suspended platform needs to be moved, the ladder 5 can be disassembled in advance to detach the ladder 5 from the side platform and the suspended platform.

At the same time, two sets of hanging components 9 are installed on the suspension platform to cooperate with the two sets of suspension rails, thereby reducing the load on the suspension mechanism 2 and improving the stability of the suspension platform.

[0046] In some alternative embodiments: see Figures 1 to 12 As shown, this application embodiment provides a mobile railway suspension platform. The suspension component 9 of the mobile railway suspension platform includes a fixed rod 93 installed on the suspension platform, and an upper steel pipe 91 and a lower steel pipe 92 installed on the fixed rod 93 and slidably connected to the suspension rail.

[0047] The hanging member 9 in the embodiment of the present application comprises a fixing rod 93 fixed on the suspension platform, and an upper steel pipe 91 and a lower steel pipe 92 fixed on the fixing rod 93. For example, the hanging rail comprises two I-shaped steels fixed on the bottom surface of the bridge and arranged in parallel. The bottom end of the fixing rod 93 is fixedly connected to the suspension platform through a fourth fastener 94. The upper steel pipe 91 and the lower steel pipe 92 are welded on the fixing rod 93. The upper steel pipe 91 and the lower steel pipe 92 are arranged in parallel and form a "dry"-shaped structure with the fixing rod 93, which can be hooked on the I-shaped steels on both sides and slide along the length direction of the I-shaped steels.
