Description

Technical Field

[0001] This invention belongs to the field of pedestrian bridge technology and relates to a rotating, openable landscape pedestrian bridge. Background Technology

[0002] In many cases, pedestrian bridges are an important and effective tool for separating pedestrian and vehicular traffic, ensuring vehicle passage and pedestrian safety. Urban pedestrian overpasses and highway pedestrian overpasses mostly fall into this category. For these types of overpasses, ensuring functionality is the primary objective, hence they are called functional pedestrian bridges.

[0003] Existing pedestrian bridges are typically monolithic, directly spanning the waterway. Because the bridge structure is monolithic, it cannot be disassembled. When used in some water parks, this cannot meet the needs of boats passing underneath at certain times. Furthermore, if the flow of pedestrians on the bridge is not promptly controlled when there are too many pedestrians, the bridge structure may suffer from overload damage. Summary of the Invention

[0004] In view of this, in order to solve the problems in the prior art where the bridge body is integral and cannot be separated, it is not possible to meet the needs of boats passing under the bridge at certain times when used in some water parks, and the bridge body will be damaged due to overweight if the flow of pedestrians on the bridge is not stopped in time when there are too many pedestrians, the present invention provides a rotating opening landscape pedestrian bridge.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rotating, openable landscape pedestrian bridge includes:

[0007] Two bridge piers are set on the river channel. A first bridge deck is provided between the top of the bridge pier and the side of the river channel. A second bridge deck is provided on the top of the bridge pier. The two first bridge decks and the second bridge deck form the bridge body. Guardrails are provided on the top of both the first bridge deck and the second bridge deck.

[0008] The first transmission mechanism is installed on the bridge pier to drive the second bridge deck to rise and fall, so that the second bridge deck can rotate to disconnect the bridge body and prevent the second bridge deck from jamming with the first bridge deck.

[0009] The second transmission mechanism is installed on the bridge pier to drive the second bridge deck to move, preventing the two second bridge decks from jamming together when they rotate.

[0010] The third transmission mechanism, installed on the bridge pier, is used to drive the second bridge deck to rotate, thus breaking the bridge structure apart.

[0011] Furthermore, the first transmission mechanism includes a mounting hole opened at the top of the pier, a hydraulic cylinder installed in the mounting hole, and a connecting column fixedly connected to the output end of the hydraulic cylinder. A first oblong hole is opened at the bottom of the second bridge deck, and a second oblong hole is opened at the top of the first oblong hole. The connecting column is located within the first oblong hole, and a limiting plate is installed within the second oblong hole. The limiting plate is fixedly connected to the connecting column. Beneficial effect: Activating the hydraulic cylinder can drive the second bridge deck to rise, thereby raising the bottom of the second bridge deck to be level with the top of the first bridge deck, preventing the second bridge deck from jamming with the first bridge deck when rotating.

[0012] Furthermore, the second transmission mechanism includes a connecting plate fixedly connected to the outer wall of the hydraulic cylinder. A first motor is fixedly connected to the bottom of the connecting plate. The output shaft of the first motor passes through a first oblong hole and is located within a second oblong hole, where a first gear is fixedly fitted. A rack that meshes with the first gear is fixedly connected to one side of the inner wall of the second oblong hole. Beneficial effects: Starting the first motor drives the first gear to rotate. The arrangement of the first gear and rack allows the second bridge surface to move outwards. Simultaneously, the connecting column and the limiting plate move within the first and second oblong holes respectively, preventing the two second bridge surfaces from jamming together during rotation.

[0013] Furthermore, the third transmission mechanism includes a viewing platform fixedly fitted onto the outer wall of the bridge pier. A ring-shaped guide rail is fixedly connected to the top of the viewing platform. Two sliders are slidably fitted onto the outer wall of the ring-shaped guide rail. Two sliding columns are slidably fitted through the top of the sliders. The tops of the four sliding columns are fixedly connected to the same sliding plate. The sliding plate is slidably connected to the bottom of the second bridge deck. Two connecting plates are fixedly connected between the two sliders. A dual-axis motor is fixedly connected between the two connecting plates. A first electromagnetic clutch and a second electromagnetic clutch are respectively provided on the opposite sides of the two connecting plates. The two output shafts of the dual-axis motor pass through the two connecting plates and are fixedly connected to the input ends of the first electromagnetic clutch and the second electromagnetic clutch. A second gear is fixedly fitted onto the output end of the second electromagnetic clutch. An internal gear ring that meshes with the second gear is fixedly connected to the inner wall of the viewing platform. Beneficial effects: Starting the dual-axis motor can drive the input end of the second electromagnetic clutch to rotate. Starting the second electromagnetic clutch can drive the output end to rotate, which can drive the second gear to rotate. Through the meshing of the second gear and the internal gear ring, the dual-axis motor can be driven to move in an arc within the landscape platform. Thus, the slider can drive the second bridge surface to rotate in an arc, opening the two second bridge surfaces and breaking the bridge body.

[0014] Furthermore, an inner threaded sleeve is rotatably connected to the top of the connecting plate mentioned above. A screw is threadedly connected to the inner wall of the inner threaded sleeve. The bottom of the screw passes through the lower connecting plate, and the top of the screw is fixedly connected to the sliding plate. Beneficial effect: Rotating the inner threaded sleeve can drive the screw to rise, thereby driving the second bridge surface to rise via the sliding plate. When used in conjunction with a hydraulic cylinder, the second bridge surface can rise smoothly.

[0015] Furthermore, a second synchronous pulley is fixedly sleeved on the outer wall of the inner threaded sleeve, and a first synchronous pulley is fixedly sleeved on the output end of the first electromagnetic clutch. The outer walls of the first and second synchronous pulleys are connected by the same synchronous belt. Beneficial effects: Starting the dual-shaft motor and the first electromagnetic clutch can drive the first synchronous pulley to rotate, which in turn drives the inner threaded sleeve to rotate via the second synchronous pulley, thereby causing the sliding plate to rise, saving power and reducing manufacturing costs.

[0016] Furthermore, one side of one of the second bridge decks is fixedly connected to a post, and one side of the other second bridge deck has a socket for use with the post. Beneficial effects: The combination of the post and the socket allows the two second bridge decks to become a single unit, increasing their strength and preventing misalignment.

[0017] Furthermore, an arc-shaped block is provided on one side of the second bridge deck, and an arc-shaped groove is provided on one side of the first bridge deck to cooperate with the arc-shaped block. Beneficial effect: The arc-shaped block and arc-shaped groove facilitate the positioning of the second and first bridge decks, preventing them from misaligning.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The rotary opening landscape pedestrian bridge disclosed in this invention, when it is necessary to disconnect the bridge deck, activates the hydraulic cylinder, which can drive the second bridge deck to rise. At the same time, activates the dual-axis motor and the first electromagnetic clutch. The rotation of the dual-axis motor can drive the input end of the first electromagnetic clutch to rotate, and drive the output end of the first electromagnetic clutch to rotate. Through the first synchronous pulley, the second synchronous pulley and the synchronous belt, the inner screw sleeve can be driven to rotate. The rotation of the inner screw sleeve can drive the screw to rise, thereby driving the second bridge deck to rise simultaneously with the hydraulic cylinder until the bottom of the second bridge deck is level with the top of the first bridge deck.

[0020] 2. The rotary opening landscape pedestrian bridge disclosed in this invention starts the first motor, which drives the first gear to rotate. The rotation of the first gear can drive the rack to move, thereby causing the second bridge surface to slide outward on the sliding plate until the insertion post disengages from the insertion hole.

[0021] 3. The rotary opening landscape pedestrian bridge disclosed in this invention closes the first electromagnetic clutch and activates the second electromagnetic clutch. The rotation of the dual-shaft motor can drive the input end of the second electromagnetic clutch to rotate, which in turn drives the output end of the second electromagnetic clutch to rotate, thereby driving the second gear to rotate. Through the meshing of the second gear with the internal gear ring, the slider can be driven to slide on the annular guide rail, causing the two second bridge surfaces to rotate relative to each other, thus breaking the bridge surface.

[0022] 4. The rotating opening landscape pedestrian bridge disclosed in this invention, when it is necessary to cross the bridge surface, starts the dual-axis motor to reverse and the second electromagnetic clutch to drive the second bridge surface to reset and rotate, so that the two second bridge surfaces correspond to each other.

[0023] 5. The rotary opening landscape pedestrian bridge disclosed in this invention starts by reversing the first motor, which drives the second bridge surface to move inward, so that the plug is inserted into the plug hole. At the same time, the hydraulic cylinder, the dual-axis motor reverses and the first electromagnetic clutch are activated. The dual-axis motor and the hydraulic cylinder can simultaneously drive the second bridge surface to descend until the arc block is stuck in the arc groove, thus completing the bridge surface connection.

[0024] In this invention, the second bridge surface can be raised by starting the hydraulic cylinder, the dual-axis motor and the first electromagnetic clutch, which can prevent the second bridge surface from jamming with the first bridge surface when rotating. Starting the first motor can drive the two second bridge surfaces to move away from each other, preventing the two second bridge surfaces from jamming. Finally, starting the dual-axis motor and the second electromagnetic clutch can drive the second bridge surface to rotate, so that the two second bridge surfaces are staggered, thereby breaking the bridge surface and facilitating use.

[0025] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention.

[0039] like Figure 8 The monolithic pedestrian bridge structure shown is not modular due to its single-piece construction and numerous piers. This prevents boats from crossing the waterway, rendering it unusable in some water parks. Furthermore, excessive pedestrian traffic can lead to overloading and damage if pedestrian flow cannot be promptly controlled. To address this issue, the following solutions are provided: Figures 1-3 The rotating, opening landscape pedestrian bridge shown includes:

[0040] Two bridge piers 1 are set on the river channel. A first bridge deck 2 is set between the top of the bridge pier 1 and the side of the river channel. A second bridge deck 3 is set on the top of the bridge pier 1. The two first bridge decks 2 and the second bridge deck 3 form the bridge body. The top of the first bridge deck 2 and the second bridge deck 3 are both equipped with guardrails 4. An arc-shaped block 33 is set on one side of the second bridge deck 3. An arc-shaped groove 34 that cooperates with the arc-shaped block 33 is set on one side of the first bridge deck 2. The setting of the arc-shaped block 33 and the arc-shaped groove 34 can facilitate the positioning of the second bridge deck 3 and the first bridge deck 2 and prevent them from being misaligned.

[0041] The first transmission mechanism is installed on the pier 1 to drive the second bridge deck 3 to rise and fall, so that the second bridge deck 3 can rotate to disconnect the bridge body and prevent the second bridge deck 3 from jamming with the first bridge deck 2.

[0042] The second transmission mechanism is installed on the pier 1 to drive the second bridge deck 3 to move, preventing the two second bridge decks 3 from jamming together when they rotate.

[0043] The third transmission mechanism, installed on the pier 1, is used to drive the second bridge deck 3 to rotate and disconnect the bridge body. The bridge body is composed of two first bridge decks 2 and two second bridge decks 3. The first, second and third transmission mechanisms can complete the rotation of the second bridge deck 3 to disconnect the bridge body. This can effectively prevent the second bridge deck 3 from jamming with the first bridge deck 2 and facilitate the protection of the bridge body.

[0044] Reference Figure 4 and Figure 7The first transmission mechanism includes an installation hole 8 on the top of the pier 1, a hydraulic cylinder 9 inside the installation hole 8, and a connecting column 14 fixedly connected to the output end of the hydraulic cylinder 9. A first waist-shaped hole 12 is opened at the bottom of the second bridge deck 3, and a second waist-shaped hole 13 is opened at the top of the first waist-shaped hole 12. The connecting column 14 is located inside the first waist-shaped hole 12, and a limiting plate 15 is provided inside the second waist-shaped hole 13. The limiting plate 15 is fixedly connected to the connecting column 14. By activating the hydraulic cylinder 9, the second bridge deck 3 can be driven to rise, so that the bottom of the second bridge deck 3 can rise to be level with the top of the first bridge deck 2, preventing the second bridge deck 3 from jamming with the first bridge deck 2 when rotating.

[0045] Reference Figure 4 and Figure 7 The second transmission mechanism includes a connecting plate 10 fixedly connected to the outer wall of the hydraulic cylinder 9. A first motor 11 is fixedly connected to the bottom of the connecting plate 10. The output shaft of the first motor 11 passes through the first oblong hole 12 and is located in the second oblong hole 13, and a first gear 17 is fixedly sleeved thereon. A rack 16 that meshes with the first gear 17 is fixedly connected to one side of the inner wall of the second oblong hole 13. By starting the first motor 11, the first gear 17 can be driven to rotate. By setting the first gear 17 and the rack 16, the second bridge surface 3 can be driven to move outward. At the same time, the connecting column 14 and the limiting plate 15 move in the first oblong hole 12 and the second oblong hole 13 respectively to prevent the two second bridge surfaces 3 from jamming each other when rotating.

[0046] Reference Figures 3-5 The third transmission mechanism includes a viewing platform 5 fixedly mounted on the outer wall of the bridge pier 1. A ring-shaped guide rail 6 is fixedly connected to the top of the viewing platform 5. Two sliders 7 are slidably mounted on the outer wall of the ring-shaped guide rail 6. Two sliding columns 19 are slidably mounted through the top of each slider 7. A single sliding plate 20 is fixedly connected to the top of each of the four sliding columns 19. The sliding plate 20 is slidably connected to the bottom of the second bridge deck 3. Two connecting plates 21 are fixedly connected between the two sliders 7. A single dual-axis motor 22 is fixedly connected between the two connecting plates 21. A first electromagnetic clutch 23 and a second electromagnetic clutch 24 are respectively located on the opposite sides of the two connecting plates 21. The two output shafts of the dual-axis motor 22 each pass through the two connecting plates 21 and are connected to the first electromagnetic clutch 24. The input ends of the magnetic clutch 23 and the second electromagnetic clutch 24 are fixedly connected. The output end of the second electromagnetic clutch 24 is fixedly fitted with the second gear 25. The inner wall of the viewing platform 5 is fixedly connected with an internal gear ring 18 that meshes with the second gear 25. By starting the dual-axis motor 22, the input end of the second electromagnetic clutch 24 can be driven to rotate. Starting the second electromagnetic clutch 24, the input end of the second electromagnetic clutch 24 can drive the output end to rotate, which can drive the second gear 25 to rotate. Through the meshing of the second gear 25 and the internal gear ring 18, the dual-axis motor 22 can be driven to move in an arc within the viewing platform 5. Thus, the second bridge surface 3 can be driven to rotate in an arc through the slider 7, opening the two second bridge surfaces 3 and breaking the bridge body.

[0047] Reference Figure 5 An inner threaded sleeve 27 is rotatably connected to the top of the upper connecting plate 21. A screw 30 is threadedly connected to the inner wall of the inner threaded sleeve 27. The bottom of the screw 30 passes through the lower connecting plate 21, and the top of the screw 30 is fixedly connected to the sliding plate 20. In the above technical solution, rotating the inner threaded sleeve 27 can drive the screw 30 to rise, thereby driving the second bridge surface 3 to rise through the sliding plate 20. When used with the hydraulic cylinder 9, the second bridge surface 3 can rise smoothly. A second synchronous wheel 28 is fixedly sleeved on the outer wall of the inner threaded sleeve 27. A first synchronous wheel 26 is fixedly sleeved on the output end of the first electromagnetic clutch 23. The outer walls of the first synchronous wheel 26 and the second synchronous wheel 28 are connected to the same synchronous belt 29. Starting the dual-shaft motor 22 and the first electromagnetic clutch 23 can drive the first synchronous wheel 26 to rotate, which in turn drives the inner threaded sleeve 27 to rotate through the second synchronous wheel 28, thereby driving the sliding plate 20 to rise. This saves power and reduces manufacturing costs.

[0048] Reference Figure 6 One of the second bridge decks 3 is fixedly connected to one side of a post 32, and the other second bridge deck 3 has a socket 31 on one side that works with the post 32. The two second bridge decks 3 can be integrated into one unit by the cooperation of the post 32 and the socket 31, which increases their toughness and prevents the two second bridge decks 3 from being misaligned.

[0049] However, as is well known to those skilled in the art, the working principles and wiring methods of the hydraulic cylinder 9, the first motor 11, the dual-shaft motor 22, the first electromagnetic clutch 23, and the second electromagnetic clutch 24 are commonplace and belong to conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0050] The working principle and usage process of this rotary-opening pedestrian bridge are as follows: When in use, connect the power supply. When it is necessary to disconnect the bridge deck, activate hydraulic cylinder 9. Hydraulic cylinder 9 can drive the second bridge deck 3 to rise. Simultaneously, activate dual-axis motor 22 and first electromagnetic clutch 23. The rotation of dual-axis motor 22 can drive the input end of the first electromagnetic clutch 23 to rotate, which in turn drives the output end of the first electromagnetic clutch 23 to rotate. Through the first synchronous pulley 26, second synchronous pulley 28, and synchronous belt 29, the inner threaded sleeve 27 can rotate. The rotation of the inner threaded sleeve 27 can drive the screw 30 to rise, thus simultaneously driving the second bridge deck 3 to rise with hydraulic cylinder 9 until the bottom of the second bridge deck 3 is level with the top of the first bridge deck 2. Activate first motor 11. First motor 11 drives first gear 17 to rotate. The rotation of first gear 17 can drive rack 16 to move, thus causing the second bridge deck 3 to slide outwards on sliding plate 20 until the insertion post 32 disengages from the insertion hole. 31. Close the first electromagnetic clutch 23 and activate the second electromagnetic clutch 24. The rotation of the dual-shaft motor 22 can drive the input end of the second electromagnetic clutch 24 to rotate, which in turn drives the output end of the second electromagnetic clutch 24 to rotate, thereby driving the second gear 25 to rotate. Through the meshing of the second gear 25 with the internal gear ring 18, the slider 7 can be driven to slide on the annular guide rail 6, causing the two second bridge surfaces 3 to rotate relative to each other, thus disconnecting the bridge surfaces. When it is necessary to pass through the bridge surfaces, activate the dual-shaft motor 22 to reverse and the second electromagnetic clutch 24 to drive the second bridge surfaces 3 to reset and rotate, so that the two second bridge surfaces 3 correspond. Activate the first motor 11 to reverse and drive the second bridge surfaces 3 to move inward, so that the insert 32 is inserted into the insertion hole 31. At the same time, activate the hydraulic cylinder 9, the dual-shaft motor 22 to reverse and the first electromagnetic clutch 23. The dual-shaft motor 22 and the hydraulic cylinder 9 can simultaneously drive the second bridge surfaces 3 to descend until the arc block 33 is inserted into the arc groove 34, thus completing the connection of the bridge surfaces.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
