Description

Technical Field

[0001] This invention relates to the technical field of electrically controlled passageways for dock boarding platforms, and more particularly to an electrically controlled passageway for a dock boarding platform. Background Technology

[0002] At the dock, passengers boarding cruise ships and other vessels must pass through a boarding platform. This platform is located at the end of the boarding bridge and extends to connect with the ship's hull. Due to varying ship sizes and the different gaps required when the ship docks, the boarding platform needs to be retractable. For example, the boarding bridge canopy device and its driving method disclosed in patent number 201310008641.7 describe a technical solution that uses a canopy to protect a movable frame. The canopy's end is extended to the cruise ship's entrance via a driving device. However, this device has two driving mechanisms installed on the canopy, making its structure overly complex. During use, the two driving mechanisms are not synchronized, and the upper and lower parts of the canopy cannot retract synchronously. Furthermore, due to the complexity of the driving mechanisms, one of them is prone to damage, leading to uncontrollable canopy deformation. This deformation can easily exceed the elastic limit, resulting in irreversible deformation and affecting the canopy's effectiveness. Summary of the Invention

[0003] The technical problem that this invention aims to solve is that the structure of the canopy is too complex, making it prone to deformation and damage, which affects its performance.

[0004] The technical solution adopted by this invention to solve its technical problem is: an electrically controlled passageway for a dock boarding platform, including a folding canopy assembly and a folding canopy drive mechanism installed in the folding canopy assembly. The folding canopy assembly includes a front frame, an inner folding canopy and an outer folding canopy installed on the front frame. A connecting canopy is provided at the end of the inner folding canopy and the outer folding canopy away from the front frame. The outer folding canopy, the inner folding canopy, the front frame and the connecting canopy are interconnected to form an annular cavity. The folding canopy drive mechanism is disposed in the annular cavity. The folding canopy drive mechanism includes a hinge fixed on the front frame and the connecting canopy, a scissor assembly connected to the hinge, and a telescopic cylinder connected to the hinge. The scissor assembly includes several connecting rods, the ends of which are hinged to the hinge. The telescopic cylinder is fixedly connected to the hinge. The telescopic cylinder pushes the connecting rods to move through the hinge, thereby causing the scissor assembly to deform.

[0005] Furthermore, the hinge includes a slide rail base fixed to the connecting canopy and the front end frame, and a pin that is slidably inserted in the slide rail base. The pin is slidably inserted in the slide rail base, the end of the connecting rod is hinged to the pin, and the piston shaft of the telescopic cylinder is connected to the pin.

[0006] Furthermore, the slide rail base has a hinge groove, the wall of the hinge groove has a sliding groove, the pin is slidably disposed in the sliding groove, and the end of the connecting rod is rotatably inserted into the hinge groove.

[0007] Furthermore, the cylinder body of the telescopic cylinder and the slide rail base are both fixedly mounted on the same surface, and the piston shaft of the telescopic cylinder extends into the hinge groove.

[0008] Furthermore, the scissor assembly also includes a hinge pin and a hinge base, the connecting rod being rotatably inserted into the hinge pin, the hinge base being disposed on the end of the connecting rod away from the telescopic cylinder, and the end of the connecting rod being hinged to the hinge base.

[0009] Furthermore, the hinge base and the slide rail base are disposed on the same surface, and the hinge base and the slide rail base are respectively disposed at both ends of the connecting rod, and the two ends of the connecting rod are respectively hinged to the hinge base and the pin.

[0010] Furthermore, the folding canopy driving mechanism also includes a connecting rod seat installed on the outer wall of the inner folding canopy and an inner folding canopy connecting rod hinged to the connecting rod seat. The two ends of the inner folding canopy connecting rod are connected end to end to form a continuous rhomboid structure, and the connecting rod seat is located at the connection point of the two ends of the inner folding canopy connecting rod.

[0011] Furthermore, the folding canopy drive mechanism also includes a pin mounted on the connecting rod seat. The pin is fixed on the connecting rod seat and is arranged in the direction corresponding to the outer folding canopy. The inner folding canopy connecting rod is hinged to the pin.

[0012] The beneficial effects of this invention are that a folding canopy driving mechanism is added to the outer wall cavity of the passageway. The folding canopy driving mechanism uses a scissor structure to connect the front frame and the connecting canopy cloth. When the scissor structure deforms, it can control the expansion and contraction of the outer and inner canopy cloths, thereby enabling remote control of the expansion and contraction of the passageway to adapt to the use of the passageway. This allows for remote control of the expansion and contraction of the passageway. Furthermore, the scissor structure simplifies the support structure of the folding canopy assembly, enabling remote automation of the expansion and contraction process of the passageway and improving the usability of the passageway.

Detailed Implementation

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] like Figures 1 to 5 As shown, the present invention provides an electrically controlled passageway 100 for a dock boarding platform, including a folding canopy assembly 10, a folding canopy drive mechanism 20 installed in the folding canopy assembly 10, and a pedal assembly 30 installed in the folding canopy assembly 10.

[0022] The folding canopy assembly 10 includes a front frame 110, an inner folding canopy 120 mounted on the front frame 110, and an outer folding canopy 130 disposed parallel to the inner folding canopy 120.

[0023] The front frame 110 is fixed parallel to the exit edge of the boarding platform. The ends of the inner folding canopy 120 and the outer folding canopy 130 are sealed and fixed to the front frame 110. Connecting fabric is provided at the ends of the inner folding canopy 120 and the outer folding canopy 130 away from the front frame 110. The connecting fabric vertically connects the inner folding canopy 120 and the outer folding canopy 130. The inner folding canopy 120, the outer folding canopy 130, the connecting fabric, and the front frame 110 together form an annular cavity. The folding canopy drive mechanism 20 is disposed within the annular cavity. Under the connection of the front frame 110 and the connecting fabric, the outer folding canopy 130 and the inner folding canopy 120 form two layers of protective fabric, and both the inner folding canopy 120 and the outer folding canopy 130 are vertically fixed to the exit of the boarding platform.

[0024] The folding tent drive mechanism 20 includes a hinge 210 fixedly mounted on the front frame 110 and the connecting tent fabric, a scissor assembly 220 connected to the hinge 210, and a telescopic cylinder 230 connected to the hinge 210.

[0025] The hinge 210 includes a slide rail base 211 fixed to the connecting fabric and the front frame 110, and an outer pin 212 slidably inserted into the slide rail base 211. The slide rail bases 211 on the connecting fabric and the front frame 110 are arranged opposite to each other. The slide rail base 211 has a hinge groove 213, and the groove wall of the hinge groove 213 has a sliding groove 214. The outer pin 212 is slidably inserted into the sliding groove 214. The scissor assembly 220 includes several connecting rods 221 connected end to end, hinge pins 222 inserted at the connection points of the connecting rods 221, and hinge bases 223 disposed at the ends of the connecting rods 221. Each contact point of the connecting rods 221 is connected by hinge pins 222. Preferably, the connecting rods 221 are divided into hollow rods and solid rods. The hollow rods are in a hollow state and are sleeved on the solid rods. Through the nested structural design, the weight and space occupied by the scissor assembly 220 can be reduced, thereby reducing the cost of use. The hinge pin 222 is rotatably inserted at the contact position of the connecting rod 221, that is, at the middle position and both ends of the connecting rod 221. The end of the connecting rod 221 is rotatably extended into the hinge groove 213. The end of the connecting rod 221 is also hinged to the hinge pin 222. The hinge base 223 and the slide rail base 211 are arranged in parallel, and both the hinge base 223 and the slide rail base 211 are fixedly set on the same surface. The hinge base 223 and the slide rail base 211 are respectively located at both ends of the connecting rod 221. The two ends of the connecting rod 221 are respectively hinged to the hinge base 223 and the outer pin 212. The telescopic cylinder 230 is preferably an electric cylinder. The cylinder body, hinge base 223 and slide rail base 211 of the telescopic cylinder 230 are all fixedly mounted on the same surface. The telescopic cylinder 230 is only mounted on one end of the connecting rod 221. The piston shaft of the telescopic cylinder 230 is fixedly connected to the outer pin shaft 212. Under the push control of the telescopic cylinder 230, the outer pin shaft 212 can slide in the sliding groove 214, thereby causing the scissor assembly 220 to deform, causing the connecting canopy to move closer to or away from the front frame 110, thereby realizing the telescopic movement of the inner folding canopy 120 and the outer folding canopy 130.

[0026] The folding drive mechanism 20 also includes a connecting rod seat 260 fixedly installed on the inner wall of the annular cavity, an inner pin 270 installed on the connecting rod seat 260, and an inner folding connecting rod 280 hinged to the inner pin 270.

[0027] There are multiple connecting rod seats 260, which are located at the ends and middle of the inner folding canopy 120. The connecting rod seats 260 are fixed to the rigid frame of the inner folding canopy 120. The inner pin shaft 270 is fixed to the connecting rod seat 260 and is oriented towards the outer folding canopy 130. The inner folding canopy connecting rods 280 are connected end to end to form a continuous rhomboid structure. The inner pin shaft 270 is located at the connection point of the inner folding canopy connecting rods 280. The two ends of the rhomboid structure are respectively hinged to the connecting canopy cloth and the front frame 110. When the distance between the front frame 110 and the connecting canopy cloth changes, several rhomboid structures deform, thereby restricting the movement direction of the connecting canopy cloth relative to the front frame 110. The inner pin 270 ensures that the rhomboid structure is connected to the inner folding 120, thereby simultaneously restricting the movement direction of the inner folding 120. Furthermore, the rhomboid structure enhances the strength of the inner folding 120, making its deformation controllable and preventing it from deforming to the left or right.

[0028] The platform assembly 30 includes a flip-up platform 310 mounted on the front frame 110 and handrails 320 located on both sides of the platform 310. The platform 310 can rotate around the front frame 110 and connect to the other side of the hull, that is, the platform 310 crosses the inner folding canopy 120 and connects the boarding platform and the hull for boarding personnel. The handrails 320 are located on the platform 310 and provide protection for the inner folding canopy 120. By rotating the platform 310 around the front frame 110, a flat platform for passengers to pass through can be formed between the boarding platform and the hull, and handrails 320 are added at both ends of the flat platform to protect the inner folding canopy 120.

[0029] When the aforementioned dock boarding platform electrically controlled passageway 100 is in use, the telescopic cylinder 230 is first activated. Under the action of the telescopic cylinder 230, the outer pin 212 moves in the sliding groove 214. During the movement of the outer pin 212, the end of the connecting rod 221 in the scissor assembly 220 can be driven to slide back and forth in the hinge groove 213 and the sliding groove 214. The connecting rod 221 deforms through the scissor structure formed by the hinge pin 222. Driven by the scissor assembly 220, the connecting canopy moves away from the front frame 110, so that the inner folding canopy 120 and the outer folding canopy 130 extend synchronously until the outer pin 212 slides to the extreme position in the sliding groove 214, and the inner folding canopy 120 and the outer folding canopy 130 reach their maximum extension. A connecting passageway is formed between the boarding platform and the ship. Then, the step 310 is flipped until it overlaps the boarding platform and the ship. Passengers can pass through the passageway through the step 310 to achieve spatial movement.

[0030] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
