Description

Technical Field

[0001] The present invention relates to the technical field of anti-falling equipment, and in particular to a universal anti-falling mechanism suitable for integrated display facilities in integrated transportation hubs. Background Art

[0002] The passenger transport integrated display facility is a device that uses an electronic screen to display information such as train schedules, train numbers, departure stations, destinations, etc. in real time. It not only undertakes the task of displaying key information such as train timetables, train numbers, and ticket gate locations, but also plays an important role in guiding passengers' travel and improving their travel experience.

[0003] To prevent passenger transport integrated display facilities from falling, existing technologies typically connect them to the building structure via anti-fall chains. However, existing anti-fall measures suffer from limited protection and insufficient reliability. Specifically, one end of the anti-fall chain is typically connected directly to an embedded component or building structure, while the other end is connected to the equipment. When a passenger transport integrated display falls, the connection point is subjected to a significant impact and tensile force, which can easily cause the anti-fall chain to break, and it is difficult to effectively prevent the equipment from disintegrating under strong impact.

[0009] According to the universal anti-fall mechanism suitable for integrated display facilities in integrated transportation hubs provided by the present invention, the buffer assembly also includes a connecting bracket, and the connecting bracket includes a first connecting rod and a second connecting rod. The first end of the first connecting rod is hinged to the threaded seat, the second end of the first connecting rod is hinged to the first end of the second connecting rod, and the second end of the second connecting rod is hinged to the shell.

[0011] According to the universal anti-falling mechanism applicable to the integrated display facility of the integrated transportation hub provided by the present invention, coil springs are respectively provided on both sides of the rotating wheel, and the coil springs are connected to the housing.

[0012] According to the universal anti-fall mechanism suitable for integrated display facilities in integrated transportation hubs provided by the present invention, the shell includes a main body and two screw support plates, the two screw support plates are axially spaced apart on the main body, both ends of the screw are rotatably connected to the main body, and the middle part of the screw is rotatably connected to the two screw support plates; the rotating wheel is located between the two screw support plates, and the coil spring is connected to the screw support plate on the corresponding side.

[0013] According to the universal anti-falling mechanism suitable for integrated display facilities in integrated transportation hubs provided by the present invention, the shell is provided with a rope outlet, the anti-falling rope is passed through the rope outlet, and guide components are symmetrically provided on both sides of the rope outlet.

[0027] The following combination Figure 1 The present invention describes a universal anti-falling mechanism applicable to integrated display facilities in integrated transportation hubs.

[0028] See also Figure 1 As shown, the universal anti-falling mechanism applicable to the integrated display facilities of the integrated transportation hub provided by the embodiment of the present invention includes: a shell 100 and a buffer assembly 200 .

[0029] The buffer assembly 200 includes a screw 210, a rotating wheel 220 and a threaded seat 230. The screw 210 is rotatably connected to the housing 100. The rotating wheel 220 is arranged on the screw 210. An anti-fall rope 240 is wound around the rotating wheel 220. The end of the anti-fall rope 240 is configured to be connected to the integrated display facility.

[0030] Among them, a threaded portion 211 is provided on the screw 210, and the threaded seat 230 cooperates with the threaded portion 211 to drive the threaded seat 230 to move axially when the screw 210 rotates. A friction pad 250 is provided on the threaded seat 230. When the threaded seat 230 reaches the braking position, the friction pad 250 contacts the housing 100.

[0031] The universal anti-fall mechanism suitable for the integrated display facilities of the integrated transportation hub provided by the present invention is provided with a buffer assembly 200. When the integrated display facility falls, under the action of the anti-fall rope 240, the rotating wheel 220 rotates and drives the lead screw 210 to rotate synchronously. Since the threaded seat 230 cooperates with the threaded portion 211 of the lead screw 210, the lead screw 210 can drive the threaded seat 230 to move axially while rotating. After moving a set distance, the friction pad 250 on the threaded seat 230 contacts and cooperates with the shell 100, exerting a buffering effect on the lead screw 210 and the rotating wheel 220, thereby avoiding the connection point from being subjected to a huge impact tension when the integrated display facility falls, preventing the integrated display facility from disintegrating, and solving the problems of single protection and insufficient reliability of existing anti-fall measures.

[0032] The universal anti-fall mechanism can be used individually or in combination. It is selected according to the weight specifications of the comprehensive display facilities of the comprehensive transportation hub, and there is no special limitation on this.

[0033] Specifically, the universal anti-falling mechanism applicable to the integrated display facility of the integrated transportation hub provided by the present invention includes a shell 100 and a buffer assembly 200 .

[0034] Among them, the shell 100 is used to provide an installation support space for the buffer component 200, and can provide dustproof and waterproof effects to the buffer component 200 to a certain extent. When the integrated display facility falls, the shell 100 also provides a friction surface that cooperates with the friction pad 250. In order to enhance the friction effect, the part of the shell 100 corresponding to the friction pad 250 can directly use the surface of the shell 100 material to contact and cooperate with the friction pad 250, or a specific friction structure can be processed to increase the friction coefficient. For example, the friction structure can be a roughened surface, a concave-convex texture design, or coated with a material with high friction performance, thereby effectively improving the friction force and ensuring that during the falling process of the facility, the contact between the friction pad 250 and the shell 100 can generate sufficient buffering force to avoid damage to the equipment.

[0035] The buffer assembly 200 is used to apply a buffering effect to the integrated display facility when it falls, thereby preventing the connection point from being subjected to a huge impact tension when the integrated display facility falls and preventing the integrated display facility from disintegrating. The buffer assembly 200 includes a screw 210, a rotating wheel 220 and a threaded seat 230. The screw 210 is rotatably connected to the housing 100. The rotating wheel 220 is provided on the screw 210. An anti-fall rope 240 is wound around the rotating wheel 220. The end of the anti-fall rope 240 is used to connect to the integrated display facility. The screw 210 is provided with a threaded portion 211. The threaded seat 230 cooperates with the threaded portion 211 to drive the threaded seat 230 to move axially when the screw 210 rotates. The threaded seat 230 is provided with a friction pad 250. When the threaded seat 230 reaches the braking position, the friction pad 250 contacts the housing 100.

[0036] The number of threaded portions 211 on the lead screw 210 may be one or two. When there is one threaded portion 211, there is also one threaded seat 230. When the integrated display facility falls, the threaded seat 230 and friction pad 250 on one side can provide a cushioning effect. This is suitable for integrated display facilities with smaller specifications (weight). When there are two threaded portions 211, the two threaded portions 211 should be symmetrically arranged on either side of the lead screw 210, with the threads of the two threaded portions 211 rotating in opposite directions, and the distances between the initial positions of the two threaded portions 211 and the corresponding sides of the housing 100 should remain equal. When the integrated display facility falls, the threaded seats 230 and friction pad 250 on both sides can simultaneously provide a cushioning effect. This is suitable for integrated display facilities with larger specifications (weight).

[0037] The friction pad 250 can be made of rubber, polyurethane, fiber-reinforced material, or other materials with a high coefficient of friction. Rubber pads offer excellent elasticity and cushioning properties, providing a springy cushioning effect; polyurethane pads offer high wear resistance and strong friction, enabling high loads and long-term use; and fiber-reinforced material pads offer excellent wear resistance, maintaining their friction properties over extended periods of use without wearing out.

[0038] Preferably, in this embodiment, the friction pad 250 is a rubber pad. The rubber pad has good elasticity, wear resistance, and pressure resistance. It can effectively absorb the impact force when the integrated display facility falls and provide sufficient friction to prevent the facility from disintegrating or being damaged during the fall. In addition, due to the flexibility of the rubber pad, the cushioning effect can be gradually increased when the integrated display facility falls and drives the threaded seat 230 to reach the braking position. Specifically, when the threaded seat 230 initially reaches the braking position, the rubber pad will gradually deform and provide an initial cushioning effect. As the threaded seat 230 further moves, the compression and deformation of the rubber pad will gradually increase the friction force, thereby enhancing the cushioning effect, helping to effectively slow the falling speed of the facility and reduce the impact force. This gradually increasing cushioning effect can better protect the integrated display facility and prevent sudden strong impacts from causing damage or disintegration of the equipment.

[0039] See also Figure 1 As shown, according to some embodiments of the present invention, threaded portions 211 are symmetrically provided on both sides of the screw 210, and threaded seats 230 are provided on the two threaded portions 211, and the threads of the two threaded portions 211 have opposite rotation directions, so that when the screw 210 rotates, the two threaded seats 230 are driven to move in directions away from each other.

[0040] By symmetrically arranging two threaded portions 211 with opposite thread rotation directions on both sides of the screw 210, when the integrated display facility falls and drives the screw 210 to rotate, the two threaded seats 230 can be driven to move in directions away from each other. When the two threaded seats 230 reach the braking position, the two friction pads 250 respectively contact the corresponding sides of the shell 100 to provide buffering, which can further optimize the buffering effect when the integrated display facility falls.

[0041] See also Figure 1 As shown, according to some embodiments of the present invention, the buffer assembly 200 also includes a connecting bracket 260, the connecting bracket 260 includes a first connecting rod 261 and a second connecting rod 262, the first end of the first connecting rod 261 is hinged to the threaded seat 230, the second end of the first connecting rod 261 is hinged to the first end of the second connecting rod 262, and the second end of the second connecting rod 262 is hinged to the shell 100.

[0042] By providing the connecting bracket 260, the rotation of the threaded seat 230 can be limited when the screw 210 rotates, preventing the threaded seat 230 from rotating with the screw 210. At the same time, by providing the connecting bracket 260 with a first connecting rod 261 and a second connecting rod 262 that are hinged to each other, and hingedly connecting the two ends of the connecting bracket 260 to the threaded seat 230 and the housing 100 respectively, the connecting bracket 260 can be made to change a certain angle (in the process of the movement of the threaded seat 230) Figure 1), thereby preventing the connecting bracket 260 from getting stuck.

[0043] See also Figure 1 As shown, according to some embodiments of the present invention, a first universal joint 263 is provided on the threaded seat 230, the first end of the first connecting rod 261 is connected to the first universal joint 263, and a second universal joint 264 is provided on the housing 100, and the second end of the second connecting rod 262 is connected to the second universal joint 264.

[0044] By configuring the two ends of the connecting bracket 260 to be universally connected with the threaded seat 230 and the shell 100 respectively, the shape change range of the connecting bracket 260 can be further improved when the threaded seat 230 moves. Due to the influence of factors such as the vibration of the train operation, the vibration caused by the flow of people, and natural wind, the threaded seat 230 will move slightly. The setting of the above-mentioned connecting bracket 260 can produce corresponding slight shape changes when the threaded seat 230 moves slightly, thereby preventing damage to the connecting bracket 260.

[0045] See also Figure 1 As shown, according to some embodiments of the present invention, coil springs 270 are respectively provided on both sides of the rotating wheel 220 , and the coil springs 270 are connected to the housing 100 .

[0046] By arranging coil springs 270 connected to the shell 100 on both sides of the rotating wheel 220, when the integrated display facility falls, the coil springs 270 can be used to generate a reaction force on the rotating wheel 220 and the screw 210, and the reaction force can be used to generate a part of the buffering force on the integrated display facility, thereby further improving the buffering effect of the mechanism.

[0047] Specifically, when the integrated display device falls and drives the rotating wheel 220 to rotate, the coil spring 270 generates a reaction force based on its elastic properties. This reaction force not only affects the rotating wheel 220 and the lead screw 210, limiting their excessive movement, but also transmits it to the overall structure, further mitigating the impact. The elasticity of the coil spring 270 allows its cushioning strength to be gradually adjusted according to the degree of the device's fall. As the fall progresses, the coil spring 270 gradually provides a reaction force, thereby enhancing the overall cushioning effect.

[0048] In addition, during the installation and debugging of the mechanism, the coil spring 270 can automatically retract the anti-fall rope 240 and generate a pre-tightening force when the anti-fall rope 240 is fixed.

[0049] See also Figure 1As shown, according to some embodiments of the present invention, the housing 100 includes a main body 110 and two screw support plates 120, the two screw support plates 120 are axially spaced apart from each other on the main body 110, both ends of the screw 210 are rotatably connected to the main body 110, and the middle part of the screw 210 is rotatably connected to the two screw support plates 120; the rotating wheel 220 is located between the two screw support plates 120, and the coil spring 270 is connected to the screw support plate 120 on the corresponding side.

[0050] By designing the housing 100 to include a main body 110 and two screw support plates 120 , and the two screw support plates 120 are axially spaced apart from the main body 110 , more stable structural support and better force transmission can be achieved.

[0051] Specifically, both ends of the lead screw 210 are rotatably connected to the main body 110, while the middle portion of the lead screw 210 is rotatably connected to the two lead screw support plates 120, so that the lead screw 210 maintains a good balance and a precise motion trajectory during rotation. The rotating wheel 220 is located between the two lead screw support plates 120, and can effectively control the movement of the rotating wheel 220 when the lead screw 210 rotates. At the same time, the coil spring 270 is connected to the lead screw support plate 120 on the corresponding side, which can provide the required reaction force and buffering effect for the rotating wheel 220. When the integrated display facility falls or is affected by external forces, the coil spring 270 will generate an elastic reaction force through the connection with the lead screw support plate 120, effectively adjusting the movement of the rotating wheel 220 and the lead screw 210, further improving the buffering performance of the mechanism.

[0052] As an example, bearings 130 are provided at the mating locations of the main body 110 and the lead screw support plate 120 and the lead screw 210 , that is, the lead screw 210 and the housing 100 are configured to be rotatably connected by the bearings 130 .

[0053] See also Figure 1 As shown, according to some embodiments of the present invention, the shell 100 is provided with a rope outlet 140, the anti-fall rope 240 is passed through the rope outlet 140, and guide assemblies 300 are symmetrically provided on both sides of the rope outlet 140. The guide assembly 300 includes a guide wheel bracket 310 and a guide wheel 310. The guide wheel 310 is rotatably connected to the guide wheel bracket 310, and the anti-fall rope 240 is in contact with the guide wheel 310.

[0054] By providing the rope outlet 140 and symmetrically providing the guide components 300 on both sides of the rope outlet 140 , effective guidance and restraint can be provided to the anti-fall rope 240 , thereby ensuring the stability of the anti-fall rope 240 .

[0055] Specifically, the guide assembly 300 includes a guide wheel bracket 310 and a guide wheel 310. The guide wheel 310 is rotatably connected to the guide wheel bracket 310, and the anti-fall rope 240 contacts the guide wheel 310, thereby ensuring smooth guidance of the anti-fall rope 240. The function of the guide assembly 300 is to guide the anti-fall rope 240 in the correct direction when it passes through the rope outlet 140, preventing the rope from deviating during operation and ensuring that the rope always moves along the predetermined path. The rotation of the guide wheel 310 prevents friction between the anti-fall rope 240 and other components, extending the rope's service life, reducing wear, and improving the safety of the entire system.

[0056] See also Figure 1 As shown, according to some embodiments of the present invention, the anti-falling rope 240 is wound around the rotating wheel 220 in a laminated manner. When the threaded seat 230 reaches the braking position, the amount of the anti-falling rope 240 on the rotating wheel 220 is greater than or equal to two layers.

[0057] By winding the anti-fall rope 240 around the rotating wheel 220 in a laminated manner and designing it so that when the threaded seat 230 reaches the braking position, the amount of anti-fall rope 240 on the rotating wheel 220 is greater than or equal to two layers, the inter-layer friction of the rope can be fully utilized to achieve buffering when the threaded seat 230 reaches the braking position, thereby avoiding all impact force from acting on the knot buckle (the connection between the anti-fall rope 240 and the rotating wheel 220).

[0058] See also Figure 1 As shown, according to some embodiments of the present invention, the universal anti-fall mechanism applicable to the integrated display facility of the integrated transportation hub further includes a mounting seat 400 , and the shell 100 is disposed on the mounting seat 400 .

[0059] By providing mounting base 400, the mechanism can be installed in a desired location, such as below the ceiling of a waiting hall, above a platform, or in a prominent location near a station entrance in a high-speed rail station. Furthermore, high-speed rail stations have complex structures, including concrete and steel. Mounting base 400 allows the mechanism to be installed in various locations within the building, thereby expanding its applicability.

[0060] As an example, in this embodiment, strip-shaped mounting holes 410 are provided around the mounting base. The strip-shaped mounting holes 410 can be used in conjunction with threaded connectors to achieve the installation and fixation of the mechanism, and the structure is simple and easy to assemble and disassemble.

[0061] In the embodiment of the present invention, the maximum force of the anti-fall rope 240 is Please see the following formula.

[0062] ; in, To comprehensively display the displacement of facilities (known fixed values), is the displacement during deceleration (a known fixed value), m is the mass of the integrated display facility (a known fixed value), is the number of universal fall protection mechanisms (a known fixed value).

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
