Abstract
Description
Technical Field
[0001] This invention relates to the field of retractable walkway technology, and in particular to a segmented, liftable, retractable walkway. Background Technology
[0002] In industrial plants, logistics and warehousing parks, and enclosed factory areas, it is often necessary to set up cross-passage bridges between two relatively independent buildings to enable unimpeded transfer of personnel and materials across buildings around the clock, avoid the impact of outdoor rain, snow, dust and other environmental factors on passage, and improve passage efficiency and transfer safety.
[0003] Currently, most building-to-building corridors are designed as fixed steel structures. These structures are fixedly connected to the building walls at both ends via steel supports, forming a permanent passageway. However, these fixed corridors have significant drawbacks: their structure permanently occupies the ground-level passageway space between buildings. When work vehicles, large production equipment, or fire trucks need to pass through the passageway, the fixed corridor will create a rigid spatial obstruction, failing to meet the dual needs of pedestrian, logistics, and vehicle passage, and exhibiting extremely poor site adaptability. Therefore, a segmented, liftable, and retractable corridor is proposed. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a segmented, liftable, and retractable covered walkway.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: including a first fixed corridor bridge, a telescopic corridor bridge, and a second fixed corridor bridge, wherein the telescopic corridor bridge is located between the first fixed corridor bridge and the second fixed corridor bridge, and the first fixed corridor bridge and the second fixed corridor bridge are respectively provided with walls on the side away from the telescopic corridor bridge, and the walls are provided with passages. The first fixed walkway includes a support frame 1, a canopy 1, and a platform 1. The support frame 1 is fixedly connected to the wall and communicates with the passageway. The canopy 1 is fixedly connected to the top of the support frame 1. The platform 1 slides longitudinally within the support frame 1. The bottom of the support frame 1 is provided with a lifting component fixedly connected to the platform 1 for driving the platform 1 to rise and fall. The telescopic walkway includes a support frame 2, a canopy 2, and a platform 2. The support frame 2 slides within the support frame 1. The canopy 2 and the platform 2 are fixedly connected to the top and bottom of the support frame 2, respectively. The bottom of the platform 2 is provided with a driving component for driving the support frame 2 to move. The second fixed walkway includes a support frame 3, a canopy 3, and a platform 3. The support frame 3 is fixedly connected to the wall and communicates with the passageway. The canopy 3 and the platform 3 are fixedly connected to the top and bottom of the support frame 3. The platform 3 is horizontal to the platform 2.
[0006] As a further description of the above technical solution: The lifting assembly is provided in two sets. The lifting assembly includes a hydraulic cylinder, a connecting plate, and a connecting rod. The hydraulic cylinder is fixedly installed on the ground. The connecting plate is fixedly connected to the output end of the hydraulic cylinder. The connecting rod is provided in several sets. The two ends of the connecting rod are respectively fixedly connected to the bottom of the connecting plate and the platform.
[0007] As a further description of the above technical solution: The drive assembly includes a dual-head motor, a drive shaft, and wheels. The dual-head motor is fixedly connected to the bottom of the second platform. The drive shaft is fixedly connected to the output end of the dual-head motor. The wheels are fixedly connected to the end of the drive shaft away from the dual-head motor and are rotatably connected to the bottom of the second platform.
[0008] As a further description of the above technical solution: The bracket has a support platform on the side away from the wall, and the hydraulic cylinder is located between the wall and the support platform.
[0009] As a further description of the above technical solution: One set of wheels is attached to the top of the support platform, and the other set of wheels is attached to the ground.
[0010] As a further description of the above technical solution: The top of the support platform is provided with a stop block corresponding to the position of the wheel. The second platform is provided with a lower slope on the side near the first platform. The first platform is provided with an upper slope corresponding to the second platform. The bottom inner side of the first bracket is provided with a limiting groove. Several sets of rollers are rotatably connected in the limiting groove. The two sides of the second platform are respectively provided with extension plates. The extension plates are slidably connected in the limiting groove and fit against the rollers.
[0011] The present invention has the following beneficial effects: 0. In this invention, a three-section segmented structure design is adopted, consisting of a first fixed corridor bridge, a telescopic corridor bridge, and a second fixed corridor bridge. When the two ends of the telescopic corridor bridge are respectively connected to the first fixed corridor bridge and the second fixed corridor bridge, a closed passage corridor bridge connecting the two end wall passages can be formed, meeting the needs of barrier-free transfer of personnel and materials. When the telescopic corridor bridge is retracted into the interior of the first fixed corridor bridge, an unobstructed passage space is formed between the first fixed corridor bridge and the second fixed corridor bridge, which can meet the barrier-free passage of operating vehicles, large equipment, and fire trucks.
[0012] 0. In this invention, the sliding cooperation between the inner limiting groove of the support frame one, the rollers, and the extension plate of the platform two limits the movement of the telescopic bridge, effectively preventing the risk of derailment. It also converts sliding friction into rolling friction, reducing frictional resistance during the telescopic process, reducing structural wear, and extending the service life of the equipment. The arc-shaped stop at the end of the support platform can limit the docking stroke of the telescopic bridge. The fit and docking structure of the upper and lower inclined surfaces between platform one and platform two achieves tight fit and locking after docking, effectively preventing the telescopic bridge from shaking and shifting, and improving the structural stability and passage safety in the docking state.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.
[0016] In order to solve the problems mentioned in the background art, this application embodiment designs a segmented liftable telescopic corridor bridge, including a first fixed corridor bridge 1, a telescopic corridor bridge 2, and a second fixed corridor bridge 3. The telescopic corridor bridge 2 is located between the first fixed corridor bridge 1 and the second fixed corridor bridge 3. The first fixed corridor bridge 1 and the second fixed corridor bridge 3 are respectively provided with a wall 41 on the side away from the telescopic corridor bridge 2, and a passage 42 is provided on the wall 41. The first fixed walkway 1 includes a support frame 11, a canopy 12, and a platform 13. The support frame 11 is fixedly connected to the wall 41 and connected to the passage 42. The canopy 12 is fixedly connected to the top of the support frame 11. The platform 13 slides longitudinally within the support frame 11. The bottom of the support frame 11 is provided with a lifting component 5 fixedly connected to the platform 13 for driving the platform 13 to rise and fall. The telescopic walkway 2 includes a support frame 21, a canopy 22, and a platform 23. The support frame 21 slides within the support frame 11. The canopy 22 and the platform 23 are fixedly connected to the top and bottom of the support frame 21, respectively. The bottom of the platform 23 is provided with a driving component 6 for driving the support frame 21 to move. The second fixed walkway 3 includes a support frame 31, a canopy 32, and a platform 33. The support frame 31 is fixedly connected to the wall 41 and connected to the passage 42. The canopy 32 and the platform 33 are fixedly connected to the top and bottom of the support frame 31. The platform 33 is horizontal to the platform 23.
[0017] In this embodiment, the width and height of bracket 11 and bracket 31 are the same. The wall 41 is provided with two sets of symmetrically arranged channels 42 with the same size. A high-speed door is installed on the outside of the channel 42. The high-speed door, lifting assembly 5 and drive assembly 6 are electrically connected to the control box. The control box is used to control the opening and closing of the high-speed door, the lifting of platform 13 and the movement of bracket 21. When bracket 21 moves into bracket 11, a space is formed in the middle of bracket 11 and bracket 21, which allows the work vehicle to pass through. When bracket 21 is attached to bracket 31, it can pass from one channel 42 to another channel 42 with the help of platform 13, platform 23 and platform 33.
[0018] like Figure 1-3 As shown, in some embodiments, the lifting assembly 5 is provided in two sets. The lifting assembly 5 includes a hydraulic cylinder 51, a connecting plate 52, and a connecting rod 53. The hydraulic cylinder 51 is fixedly installed on the ground, the connecting plate 52 is fixedly connected to the output end of the hydraulic cylinder 51, and the connecting rod 53 is provided in several sets. The two ends of the connecting rod 53 are respectively fixedly connected to the connecting plate 52 and the bottom of the platform 13. The drive assembly 6 includes a dual-head motor 61, a drive shaft 62, and a wheel 63. The dual-head motor 61 is fixedly connected to the bottom of the platform 23, the drive shaft 62 is fixedly connected to the output end of the dual-head motor 61, and the wheel 63 is fixedly connected to the end of the drive shaft 62 away from the dual-head motor 61. The wheel 63 is rotatably connected to the bottom of the platform 23.
[0019] Among them, the support platform 7 is provided on the side of the bracket 11 away from the cavity, and the hydraulic cylinder 51 is located in the middle between the cavity and the support platform 7; one set of wheels 63 is attached to the top of the support platform 7, and another set of wheels 63 is attached to the ground.
[0020] In some embodiments, four vertically distributed ball screws are used, each driven by a servo motor. Screw nuts are connected to the four corners of the platform 1. The four servo motors drive the four sets of ball screws to rotate synchronously, and the platform 1 is raised and lowered under the action of the screw nuts. At the output end of the dual-head motor 61, there are worm gear reducers and brake devices respectively. The worm gear reducer is connected to the drive shaft 62 and uses an electromagnetic brake. The electromagnetic brake is installed on the drive shaft 62 and can directly stop the drive shaft 62 and lock the wheel 63.
[0021] In this embodiment, the platform 13 is raised and lowered by two sets of lifting mechanisms, and several sets of connecting rods 53 are provided to ensure the support capacity of the platform 13 and ensure stability during passage. The wall 41, support platform 7, a set of wheels 63 are level with the bottom of the bracket 11 and bracket 31 to enhance the stability of the overall structure support. Two sets of drive components 6 are respectively arranged on both sides of the platform 23 to provide stable support. Hydraulic cylinder 51 drives the top of platform 13 to be horizontal with the top of support platform 7. The wheel 63, which is attached to the top of support platform 7, can roll along platform 13, thereby retracting bracket 21 into bracket 11. The length of canopy 12 is greater than the length of the platform. The length of canopy 22 is the same as the length of bracket 21. The length of platform 23 is the same as the length of canopy 12. When a set of drive components 6 is attached to support platform 7, the two sides of bracket 21 are horizontal with the two sides of bracket 11.
[0022] like Figure 1-5 As shown, in some embodiments, the top of the support platform 7 is provided with a stop block 81 corresponding to the position of the wheel 63, the side of the second platform 23 near the first platform 13 is provided with a lower inclined surface 82, the side of the first platform 13 near the second platform 23 is provided with an upper inclined surface 83 corresponding to the second platform 23, the bottom inner side of the bracket 11 is provided with a limiting groove 91, and several sets of rollers 92 are rotatably connected in the limiting groove 91. The two sides of the second platform 23 are respectively provided with extension plates 93, and the extension plates 93 are slidably connected in the limiting groove 91 and fit against the rollers 92.
[0023] In this embodiment, the side of the stop block 81 facing the support 11 is arc-shaped. When the platform 23 is connected to the platform 33, the wheel 63 is in contact with the arc-shaped edge of the stop block 81. When the platform 13 is pushed horizontally to the platform 23, the upper inclined surface 83 is in contact with the lower inclined surface 82. This not only prevents the support 21 from shaking, but also allows the platform 23 to be tightly attached to the platform 13 and the platform 33 through the upper inclined surface 83 and the lower inclined surface 82. When the dual-head motor 61 drives the wheel 63 to move, the platform 23 moves. At this time, the roller 92 that is in contact with the extension plate 93 rotates, reducing the friction of the extension plate 93 in the limiting groove 91. To better understand the working process of a segmented, liftable, and retractable walkway according to an embodiment of this application, refer to... Figure 1 - Figure 5 The following is a specific embodiment: When the telescopic bridge 2 and the second fixed bridge 3 are in a docked state, and it is necessary to move the telescopic bridge 2 to allow vehicles to pass, the control box is activated, the fast doors in the two side passages 42 are closed, the hydraulic cylinder 51 drives the platform 13 to descend through the connecting plate 52 and the connecting rod 53, and moves it to the top of the horizontal support platform 7. Then, two sets of dual-head motors 61 are activated. The dual-head motors 61 drive the wheels 63 to rotate through the drive shaft 62, so that the telescopic bridge 2 moves towards the first fixed bridge 1. At this time, one set of wheels 63 rolls on the ground, and the other set of wheels 63 rolls on the top of the support platform 7 and the platform 13. At the same time, the extension plate 93 slides in the limiting groove 91 and drives the roller 92 to roll. After the telescopic bridge 2 moves into the first fixed bridge 1, it stops, and the road between the first fixed bridge 1 and the second fixed bridge 3 is clear. When the first fixed corridor bridge 1 and the second fixed corridor bridge 3 are separated, and when it is needed as a logistics channel 42 between the two sets of cavities, the control box is started, and the dual-head motor 61 is started to drive the telescopic corridor bridge 2 to move towards the second fixed corridor bridge 3 until the second platform 23 is attached to the third platform 33. Then the hydraulic cylinder 51 is started to push the first platform 13 to rise and be horizontal with the second platform 23. Then the fast doors on both sides can be opened.
[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
