Description

Technical Field

[0001] This invention relates to the field of canopy construction technology, specifically to a support platform for railway station canopy construction. Background Technology

[0002] Station canopies are structures that provide shelter for passengers while waiting for trains. They are usually made of roofs or coverings erected above station platforms. Currently, there are two main types of station canopies: steel structure canopies and concrete canopies. Steel structure canopies are lightweight and easy to install, while concrete canopies have good durability. During the construction and erection of station canopies, operating platforms are usually one of the essential tools. An operating platform is a temporary structure used to support workers and materials, providing a safe working platform and convenient construction conditions, enabling workers to perform high-altitude operations, such as installing canopy structures and covering materials.

[0003] Existing operating platforms have several problems during operation. For example, a type of construction scaffolding with publication number CN109113317B, while allowing for quick disassembly and fixing and replacement of support structures, presents safety hazards in actual use. Workers cannot easily and stably climb onto the platform or safely descend from it, leading to reduced work efficiency. Furthermore, existing operating platforms offer poor protection for workers. Although workers wear safety harnesses connected to the platform, providing protection, issues arise during canopy construction. In severe weather conditions (such as strong winds, storms, tornadoes, etc.), the stability of the station canopy during construction may be threatened. Since the canopy is not yet fully constructed, excessive wind force may exert a huge lateral force on the canopy structure, causing structural instability and posing a risk of collapse. When the canopy is about to collapse, workers cannot get off the operating platform in time. The existing operating platform cannot provide workers with a simple protective shelter during the work process, thus failing to effectively prevent physical injury to workers from the collapsing canopy. Its practicality and safety are poor. Therefore, it is necessary to provide a support platform for the construction of station canopies to meet the needs of users. Summary of the Invention

[0004] This invention proposes a support platform for the construction of station canopies, which solves the problems in related technologies where the operating platform cannot be easily and stably climbed onto the work platform, nor can it be easily and safely descended from the work platform, and it cannot provide workers with a simple protective shelter in a timely manner, thus failing to effectively prevent physical injury to workers caused by collapsing canopies.

[0015] The working principle and beneficial effects of this invention are as follows:

[0016] 1. This invention includes a safety climbing component. After the operating platform is moved to a suitable working position using casters, the operator can drive a servo motor. At this time, the first bevel gear, through the second bevel gear, drives the first threaded rod to rotate, which in turn drives the support plate to move outward. The support plate then drives each of the first telescopic sleeves to tilt and rotate. The various pedals are stably arranged and suspended using steel cables, forming a ladder. By stepping on each pedal, the operator can easily and safely climb onto the work platform. Similarly, by stepping on each pedal, the operator can easily and safely move to the ground, effectively improving the safety of climbing up and down the operating platform. The platform is comprehensive and convenient. During operation, when the height is adjusted using hydraulic rods, the number of pedals and steel ropes can automatically increase or decrease. The pedals are also evenly distributed, ensuring stability during subsequent climbing and enhancing the platform's practicality and applicability. Furthermore, after the platform moves to the working position, the outward movement of the side support plates, along with the steel wire rope on the traction coil, drives the second threaded rod to rotate automatically. This, combined with the connecting plate, causes the anti-slip pad at the bottom of the extrusion plate to contact the ground, increasing friction and thus improving the platform's stability and operational safety.

[0017] This invention includes an emergency protection component. When workers encounter severe weather or emergencies while constructing a canopy on the work platform, they can quickly pull the stop bar on the fixed frame outward. At this time, the second telescopic sleeve rod, using its internal powerful spring, can drive the connecting plate to move upward quickly and detach from the fixed frame. Then, under the combined action of the second and third springs, the first and second protective plates can automatically extend. The first and second protective plates on both sides can quickly form a simple protective canopy, allowing workers to quickly take shelter under the simple protective canopy for emergency protection, thus increasing the versatility and safety of the operating platform.

[0018] This invention includes a safety harness and a safety belt. During canopy construction on the operating platform, workers must wear the safety belt. The stop block on the fourth spring allows for convenient and stable engagement and disengagement of the safety belt. This engagement and disengagement facilitates easy connection and disconnection between the safety belt and the operating platform, making it easier for workers to get on and off. Furthermore, while workers are wearing the safety belt and constructing the canopy on the platform, the elasticity of the second spiral spring causes the drum on the rotating shaft to automatically rewind the harness. Therefore, the harness remains secure during operation, preventing it from becoming loose and overcoming the tripping hazard of a loose harness. This improves the ease of use of the operating platform and enhances construction safety.

[0019] This invention includes a base frame and support columns. The base frame, support columns, and work platform are mounted on the canopy support pillars using bolts, thereby providing stable support and limiting the overall operation platform. Since the road surface is only repaired after the canopy construction is completed, construction pits are commonly present on the ground during the canopy construction process, making it difficult to lay the operation platform. Therefore, using the support and limiting function of the canopy support pillars can effectively improve the overall safety of the operation platform and ensure the stability and safety of the operation platform in subsequent operation.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figures 1-15As shown, this embodiment proposes a support platform for the construction of a station canopy, including a base frame 1. A hydraulic rod 2 is installed on the top surface of the base frame 1. A support column 3 is fixedly connected to the top of the hydraulic rod 2. A reinforcing rod 4 is bolted to the side end of the support column 3. A work platform 5 is bolted to the top of the reinforcing rod 4. The top of the support column 3 is fixedly connected to the bottom surface of the work platform 5. A guardrail 6 is fixedly connected to the top surface of the work platform 5. A caster wheel 7 is installed on the bottom surface of the base frame 1. A cleaning brush 8 is fixedly connected to the bottom surface of the base frame 1. A safety climbing component 9 is installed on the base frame 1. An emergency protection component 10 is installed on the work platform 5. The emergency protection component 10 includes a damping cylinder 1001 and a shock-absorbing spring 1002. The bottom end of the damping cylinder 1001 and the shock-absorbing spring 1002... The bottom ends of components 2 are fixedly connected to the top surface of the workbench 5. The top ends of the damping cylinder 1001 and the shock-absorbing spring 1002 are fixedly connected to the bottom surface of the fixed frame 1003. A fourth spring 11 is fixedly connected inside the fixed frame 1003. A stop block 12 is fixedly connected to the other end of the fourth spring 11. The stop block 12 is slidably connected inside the fixed frame 1003. A collar 13 is fitted on the fixed frame 1003. A drawstring 14 is fixedly connected to the collar 13. A safety belt 15 is fixedly connected to the other end of the drawstring 14. The drawstring 14 is slidably connected inside the storage frame 16. A second limiting frame 17 is fixedly connected inside the storage frame 16. A second spiral spring 18 is fixedly connected inside the second limiting frame 17. The inner end of the second spiral spring 18 is fixed... A rotating shaft 19 is connected and rotatably connected inside the storage frame 16. A roller 20 is fixedly connected to the rotating shaft 19. The middle part of the drawstring 14 passes through and is fixed inside the roller 20, and the drawstring 14 is wound around the roller 20. Two base frames 1, two support columns 3, and two work platforms 5 are provided. The two base frames 1, two support columns 3, and two work platforms 5 are all fitted onto the canopy support column 21. The two base frames 1 are connected by bolts. A safety climbing component 9 can be used to easily form a ladder. Workers can easily and safely climb to the work platform 5 by using the ladder, which effectively improves the safety and convenience of going up and down the operating platform. In addition, the safety climbing component 9 can contact the ground during operation, increase friction, and thus improve the placement stability of the operating platform, further improving the operation. The platform ensures operational safety. In the event of an emergency such as a canopy collapse during canopy construction on workbench 5, workers can quickly activate the emergency protection component 10 to rapidly form a simple protective shelter. Workers can then quickly take shelter under this shelter for emergency protection, preventing injury from the collapsing canopy. Furthermore, workers must wear safety harnesses 15 while constructing the canopy on the platform. Under the elastic action of the second spiral spring 18, the drum 20 on the rotating shaft 19 automatically winds up the reel belt 14, preventing it from becoming loose during operation.This design overcomes the drawback of loose cable ties (14) that could easily trip workers, improving the ease of use of the operating platform and enhancing construction safety.

[0040] Example 2

[0041] like Figures 1-15 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a support platform for the construction of station canopies.

[0042] In this embodiment, the top of the hydraulic rod 2 is fixed to the middle part of the side end of the support column 3. The casters 7 are symmetrically distributed on the front and rear sides of the bottom of the base frame 1. The cleaning brushes 8 are inclined and are evenly distributed on the bottom surface of the base frame 1. During the movement of the operating platform, each cleaning brush 8 can be used to simply clean the ground that the casters 7 are about to reach, so as to avoid large impurities from affecting the movement of the casters 7 and to avoid affecting the subsequent anti-slip work.

[0043] In this embodiment, the safety climbing component 9 includes a servo motor 901 and a footboard 910. The servo motor 901 is fixedly connected to the bottom end face of the base frame 1. A first bevel gear 902 is fixedly connected to the output shaft of the servo motor 901. A second bevel gear 903 is meshed with the first bevel gear 902. A first threaded rod 904 is fixedly connected to the second bevel gear 903. The first threaded rod 904 is rotatably connected to a fixing plate 905, which is fixedly connected inside the base frame 1. A support plate 906 is threadedly connected to the first threaded rod 904 to support... Plate 906 is slidably connected to the bottom frame 1. The first threaded rod 904 is centrally symmetrically distributed in the support plates 906 on both sides. The length of the first threaded rod 904 is less than the length of the support plate 906. After the operating platform is moved to a suitable working position by using the casters 7, the operator can drive the servo motor 901. At this time, the first bevel gear 902 can drive the first threaded rod 904 on both sides to rotate simultaneously through the second bevel gear 903, which can then drive the support plates 906 on both sides to move outward simultaneously, thereby ensuring the stability of subsequent anti-slip and climbing work.

[0044] In this embodiment, a first hinge support 907 is installed on the top surface of the support plate 906. A first telescopic sleeve 908 is connected to the first hinge support 907. A second hinge support 909 is connected to the top of the first telescopic sleeve 908. The second hinge support 909 is installed on the bottom surface of the workbench 5. A through groove 911 is provided through the pedal 910. A rubber ring 912 is fixedly connected in the through groove 911. The pedal 910 is limited and slidably connected to the first telescopic sleeve 908 through the through groove 911. A steel strand 913 is fixedly connected to the pedal 910. The topmost pedal 910 is fixedly connected to the second hinge support 909. Adjacent pedals 910 are connected by steel strand 913. Two sets of the first telescopic sleeve 908 and the steel strand 913 are provided. There are two sets of each set of the first telescopic sleeve 908 and each set of steel strand 913. The two sets of the first telescopic sleeve 908 and the two sets of steel strand 913 are connected to each other. The first telescopic rods 908 and two steel ropes 913 are symmetrically distributed on the left and right sides of the pedal 910, with the support plates 906 on both sides moving outward. When the support plates 906 on both sides move outward, they can cause the first telescopic rods 908 to tilt and rotate. The pedals 910 can be stably arranged and suspended by the steel ropes 913 to form steps. Workers can easily and safely climb onto the work platform 5 by stepping on the pedals 910. Similarly, they can easily and safely move to the ground by stepping on the pedals 910, effectively improving the safety and convenience of going up and down the operating platform. During the operation of the operating platform, when the height is adjusted by the hydraulic rod 2, the number of pedals 910 and steel ropes 913 can automatically increase or decrease. At the same time, the pedals 910 can be evenly distributed to ensure the stability of subsequent climbing work, improving the practicality and applicability of the operating platform.

[0045] In this embodiment, a steel wire rope 914 is bolted to the support plate 906. The steel wire rope 914 is slidably connected inside the bottom frame 1 and is slidably connected to the guide wheel 915. The guide wheel 915 is installed on the bottom end face of the bottom frame 1. The bottom of the steel wire rope 914 is wound around a fixed coil 916. A second threaded rod 917 is fixedly connected to the fixed coil 916. The top end of the second threaded rod 917 is rotatably connected to the bottom end face of the bottom frame 1. A connecting plate 918 is threadedly connected to the second threaded rod 917. A pressing plate 919 is fixedly connected to the bottom end of the connecting plate 918. An anti-slip pad 920 is fixedly connected to the bottom end face of the pressing plate 919. The second threaded rod 917 is slidably connected inside the pressing plate 919. A first spiral spring 921 is fixedly connected to the top end of the second threaded rod 917. The outer end of the spring 921 is fixedly connected to the first limiting frame 922. The top end of the first limiting frame 922 is fixedly connected to the bottom end face of the base frame 1. The cross-section of the connecting plate 918 is "L" shaped. The sum of the lengths of the second threaded rod 917 and the connecting plate 918 is greater than the length of the universal wheel 7. The height of the bottom end face of the universal wheel 7 is less than the height of the bottom end face of the second threaded rod 917. The pressing plate 919 is parallel to the base frame 1. After the operating platform moves to the working position, during the outward movement of the two side support plates 906, the steel wire rope 914 on the traction fixing coil 916 can drive the second threaded rod 917 to rotate automatically. In conjunction with the connecting plate 918, the anti-slip pad 920 at the bottom of the pressing plate 919 can be driven to contact the ground, increasing friction and thus improving the placement stability of the operating platform, further enhancing the working safety of the operating platform.

[0046] In this embodiment, a first spring 1004 is fixedly connected to the top side of the fixed frame 1003, and a stop bar 1005 is fixedly connected to the other end of the first spring 1004. The stop bar 1005 is slidably connected within the fixed frame 1003. A second telescopic sleeve 1006 is fixedly connected within the fixed frame 1003, and a strong spring 1007 is fixedly connected within the second telescopic sleeve 1006. A connecting plate 1008 is fixedly connected to the top end of the second telescopic sleeve 1006, and a first connecting frame 1009 and a second spring 1007 are fixedly connected to the top side of the connecting plate 1008. 10. A first protective plate 1011 is rotatably connected inside the first connecting frame 1009. The other end of the second spring 1010 is fixedly connected to the first protective plate 1011. A second connecting frame 1012 is rotatably connected to the first protective plate 1011. A second protective plate 1013 is rotatably connected inside the second connecting frame 1012. A third spring 1014 is fixedly connected to the second protective plate 1013. The other end of the third spring 1014 is fixedly connected to the first protective plate 1011. The bottom of the second telescopic sleeve 1006 is fixed to the middle part inside the fixed frame 1003. The first connecting frame 1009 is symmetrically distributed on both sides of the top of the connecting plate 1008. The first connecting frame 1009 corresponds one-to-one with the first protective plate 1011. The first protective plate 1011 corresponds one-to-one with the second protective plate 1013 through the second connecting frame 1012. The length of the second protective plate 1013 is equal to the length of the first protective plate 1011. The length of the first protective plate 1011 is less than the length of the connecting plate 1008. When workers encounter emergencies such as the collapse of the canopy during the canopy construction on the workbench 5, they can quickly pull it outwards. The stop bar 1005 on the fixed frame 1003 allows the second telescopic sleeve 1006 to use the internal strong spring 1007 to drive the connecting plate 1008 to move upward quickly and detach from the fixed frame 1003. At this time, under the combined action of the second spring 1010 and the third spring 1014, the first protective plate 1011 and the second protective plate 1013 can be automatically extended. At this time, the first protective plate 1011 and the second protective plate 1013 on both sides can quickly form a simple protective shed, under which workers can quickly hide and carry out emergency protection work.

[0047] In this embodiment, the damping cylinder 1001 is fixed to the middle part of the side end of the workbench 5. The fourth spring 11 is symmetrically distributed on both sides inside the fixed frame 1003. The fourth spring 11 corresponds to the stop block 12. The end cross section of the stop block 12 is a right trapezoid. When the worker is working on the canopy on the operating platform, he needs to wear a safety belt 15. The stop block 12 on the fourth spring 11 can be used to easily and stably engage and disengage the collar 13. By engaging and disengaging the collar 13, the connection and disconnection between the safety belt 15 and the operating platform can be easily completed, thereby facilitating the worker to get on and off the operating platform.

[0048] It should be noted that this invention is a support platform for the construction of a station canopy. First, workers can push the entire operating platform, which can be easily moved using the casters 7 at the bottom of the base frame 1, until the platform reaches the canopy support pillar 21. Then, workers can remove the bolts on the base frame 1, splitting it in two. The two base frames 1 can then be fitted onto the canopy support pillar 21, at which point the support pillar 3 and the work platform 5 are also fitted onto the pillar 21. Workers can then use bolts to install and fix the two base frames 1. Although the two base frames 1 are installed and fitted onto the canopy support pillar 21, there is still a gap between the base frames 1 and the pillar 21, requiring subsequent anti-slip treatment. During the movement of the operating platform, the cleaning brushes 8 can be used to simply clean the ground where the casters 7 will reach, preventing large debris from affecting the movement of the casters 7 and avoiding interference with subsequent anti-slip work. After the operating platform is moved to a suitable position, workers can... By controlling the servo motor 901 at the bottom of the base frame 1, the first bevel gear 902 on the output shaft can be driven to rotate stably under the driving action of the servo motor 901. Under the rotation of the first bevel gear 902, the first threaded rod 904 can be driven to rotate stably on the fixed plate 905 through the meshing second bevel gear 903. Under the rotation of the first threaded rod 904, the threaded support plate 906 can be driven to move outward. Under the movement of the support plate 906, the first hinge support 907 and the second hinge support 909 can be used to drive each first telescopic sleeve rod 908 to tilt outward. During the rotation and tilting process of each first telescopic sleeve rod 908, although it will drive each pedal 910 to tilt at a certain angle, the tilt angle is small. After the staff steps on the pedal 910, under the limiting action of each through groove 911 and the support action of each steel strand 913, the pedal 910 will be horizontal, so it will not affect the staff's subsequent stepping work.

[0049] During the tilting motion of each of the first telescopic sleeves 908, under the limiting action of the through groove 911, the first telescopic sleeves 908 can move each pedal 910 to be stably arranged. At the same time, each pedal 910 can be stably suspended by the steel stranded rope 913. Therefore, each pedal 910 can stably form a step. By stepping on each pedal 910, the worker can easily and safely climb onto the work platform 5. Similarly, by stepping on each pedal 910, the worker can easily and safely move to the ground. When the operating platform needs to be height adjusted during operation, the worker can drive the hydraulic rod 2. At this time, under the driving action of each hydraulic rod 2, the platform is supported by... The column 3 and the reinforcing rod 4 can push the workbench 5 to move up or down. When the workbench 5 moves up, the second hinge support 909 on the bottom surface of the workbench 5 can drive the top pedal 910 to move up. At this time, the top pedal 910 can drive the second layer of pedals 910 to move through the steel cable 913. Similarly, when adjusting the height, each pedal 910 can automatically increase the number of suspensions in conjunction with the steel cable 913. Similarly, when the workbench 5 moves down, the pedals 910 can automatically decrease the number of suspensions in conjunction with the steel cable 913 under their own weight. At the same time, each pedal 910 can be evenly distributed during the suspension process to ensure the stability of subsequent climbing work.

[0050] Furthermore, after the operating platform moves to the working position, during the outward movement of the two side support plates 906, the two side support plates 906 can automatically pull the corresponding wire ropes 914. At this time, under the traction of the wire ropes 914, the guide wheel 915 can drive the second threaded rod 917 on the fixed coil 916 to rotate automatically. At this time, under the rotation of the second threaded rod 917, the connecting plate 918 connected by the thread can drive the pressing plate 919 to move automatically downward until the anti-slip pad 920 at the bottom of the pressing plate 919 contacts the ground to increase friction and thus improve the placement stability of the operating platform. It is not necessary to lift the operating platform. Therefore, when the anti-slip pad 920 contacts the ground, the movement of the support plate 906 can be stopped.

[0051] When the operating platform finishes its work or needs to be moved, the first bevel gear 902 can be rotated in the opposite direction by driving the servo motor 901. At this time, the first threaded rod 904 on the second bevel gear 903 can drive the support plate 906 to move and reset to the center. At this time, each of the first telescopic sleeve rods 908 moves and resets. Then, the first spiral spring 921 in the first limit frame 922 can drive the second threaded rod 917 to rotate automatically in the opposite direction. At this time, the fixed coil 916 can automatically wind up the wire rope 914 for easy reuse. At the same time, the reverse rotation of the second threaded rod 917 can drive the pressing plate 919 to move upward and reset automatically through the connecting plate 918. At this time, the operating platform can be moved conveniently by each universal wheel 7.

[0052] When workers climb onto workbench 5 to construct the canopy, they need to wear safety harnesses 15. Then, workers can put the collar 13 onto the fixed frame 1003 and press it down. At this time, using the inclined end of the stop block 12, the collar 13 pushes the two side stops 12 into the fixed frame 1003 until the collar 13 is below the stop block 12. Then, the stop block 12 automatically moves outward using the fourth spring 11. At this point, the bottom plane of the stop block 12 cooperates with the fixed frame 1003 to automatically engage the collar 13. Combined with the safety harness 15 on the drawstring 14, this provides stable safety protection for the workers. Furthermore, as workers walk on workbench 5, pulling the drawstring 14 drives the drum 20 on the rotating shaft 19 to rotate automatically, completing the unwinding of the drawstring 14. Meanwhile, under the elastic action of the second spiral spring 18 inside the second limiting frame 17, the drum 20 on the rotating shaft 19 can always provide a winding force on the drawstring 14. Therefore, the drawstring 14 will not become loose during the operation, which makes up for the defect that a loose drawstring 14 is easy to trip the workers. The length of the drawstring 14 on the drum 20 is limited. The length of the drawstring 14 is about the same as the length of the workbench 5. Therefore, when the worker falls, the drawstring 14 on the drum 20 is completely unwound. At this time, the drawstring 14 and the safety belt 15 can be used to protect the worker. When the worker finishes the work, the worker only needs to use his hands to push the blocks 12 on both sides inward. At this time, the collar 13 can be easily disengaged from the fixed frame 1003, ensuring the worker's convenience when getting off the workbench 5 of the operating platform.

[0053] During the canopy construction process on workbench 5, in case of severe weather or emergencies, workers can quickly pull outwards the stop bar 1005 on the fixed frame 1003. At this time, the obstruction of the connecting plate 1008 disappears, and the second telescopic sleeve 1006, using the internal strong spring 1007, can drive the connecting plate 1008 to move upwards quickly and detach from the fixed frame 1003. At this time, under the combined action of the second spring 1010 and the third spring 1014, the first protective plate 1011 on the first connecting frame 1009 and the second protective plate 1013 on the second connecting frame 1012 can automatically rotate and extend. At this time, the first protective plate 1011 and the second protective plate 1013 on both sides can quickly form a simple canopy. The protective shed allows workers to quickly take shelter under the simple protective shed for emergency protection. After the workers are out of danger, they can manually fold the first protective plate 1011 on the first connecting frame 1009 and the second protective plate 1013 on the second connecting frame 1012, and press down on the connecting plate 1008 until the connecting plate 1008 moves the first protective plate 1011 and the second protective plate 1013 into the fixed frame 1003. At this time, under the elastic action of the first spring 1004, the stop bar 1005 can automatically move inward to reset, thereby automatically blocking the connecting plate 1008 and ensuring the stability of the retracted state of the connecting plate 1008, thus ensuring that the connecting plate 1008 can be reused.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
