Description

Technical Field

[0001] The utility model belongs to the technical field of platform passenger protection equipment, in particular to a platform barrier component and a platform isolation protection system. Background Art

[0002] In order to ensure the safety of waiting passengers, it is necessary to configure an isolation and protection system on the platform. The applicant's earlier invention patent application with the publication number CN110641482A provides a lifting platform isolation and protection system, which includes a plurality of lifting devices arranged at intervals on the platform, and a barrier rope (barrier member) is connected between two adjacent lifting devices to block passengers. The lifting device can be regarded as an isolation connection device. Specifically, the lifting device includes a fixed column and a lifting column arranged inside the fixed column. A lifting drive mechanism is connected between the lifting column and the fixed column. Under the action of the lifting drive mechanism, the lifting column can move up and down along the fixed column. A plurality of sliders arranged vertically are provided on the lifting column, and a barrier rope is connected between the sliders on the lifting columns of two adjacent lifting devices to block passengers. At least one of the left and right sides of the fixed column is provided with a through groove for the barrier rope to pass through. The lifting column and the slider are connected by a linkage mechanism. When the lifting column rises, it can drive the slider up, thereby driving the barrier rope up to open the passage for passengers to get on and off the bus; when the lifting column falls, it can drive the slider down, thereby driving the barrier rope down to close the passage for passengers to get on and off the bus.

[0003] Barrier ropes are typically made of nylon or high-molecular polyethylene braided rope. To match the length of high-speed rail carriages, the length of the barrier rope between two adjacent lifting devices is generally around 25 meters. To attract the attention of waiting passengers, the barrier ropes are also relatively large in diameter and heavy. Under the influence of their own weight, the middle portion of the barrier rope tends to sag, which in turn subjects the lifting column in the lifting device to greater lateral tension, increasing the friction between the lifting column and the fixed column, thereby increasing the resistance of the lifting column during its ascent and descent. Furthermore, the platform is an open environment, and in windy weather, the barrier rope sags and bends in the middle, making it more likely to swing back and forth (in the direction passengers board and exit the train) under the influence of the wind, resulting in insufficient stability.

[0004] In order to improve the stability of the barrier rope, the applicant found after actual investigation that some domestic and foreign manufacturers have adopted the method of adding a steel wire core to the nylon braided rope or directly replacing the barrier rope with a steel wire rope. Although this can improve the stability of the barrier rope, it will reduce the elongation rate of the barrier rope, and the deformation and energy absorption effect of the barrier rope itself will be worse. If the barrier rope scrapes against the waiting passengers when moving up and down or the waiting passengers accidentally touch the barrier rope, it is easy to cause serious injuries.

[0005] To enhance the stability of the barrier ropes, the applicant's utility model patent, authorized under publication number CN217145965U, provides a highly wind-resistant barrier assembly. This assembly comprises a positioning bracket and multiple round ropes (barrier elements) arranged in a vertical arrangement. Connectors are located on either side of the ropes for connection to a lifting device (isolation connection device). The positioning brackets feature holes for the ropes (thin ropes) to pass through. The gaps between adjacent ropes create ventilation spaces. The positioning brackets allow the ropes to form a complete, force-bearing structure, enhancing wind resistance.

[0006] Platform isolation and protection systems using the aforementioned barrier components have been successfully deployed at numerous high-speed rail stations across China, effectively preventing passengers from crossing the safety line. However, in actual use, the applicant discovered that the relatively small diameter of the round rope (1mm-10mm) and the limited visible area made it difficult to observe and attract the attention of some passengers. This was particularly true at night or in overcast weather, when platform lighting was poor. The barrier ropes were even more difficult to observe, hindering their effectiveness as a warning. Utility Model Content

[0007] The present invention aims to provide a platform barrier assembly to address the technical problem in the prior art of using round ropes to block passengers, which results in a small visible area and an increase in the diameter of the round ropes, which easily leads to excessive weight of the barrier. The present invention also aims to provide a platform isolation and protection system to address the same technical problem.

[0008] To achieve the above objectives, the technical solution of the platform barrier assembly provided by the present invention is:

[0009] A platform barrier assembly includes a group of barrier elements and a plurality of positioning brackets for separating different barrier elements in the same group. At least one barrier element in the group is a barrier strip, the wide side of the barrier strip extends along the arrangement direction of the group of barrier elements, and the barrier element on at least one of the two adjacent sides of the barrier strip is a barrier rope.

[0010] As a further improvement, the barrier members on both adjacent sides of the barrier strip are barrier ropes.

[0011] As a further improvement, at least one barrier tape is a reflective tape.

[0012] As a further improvement, the reflective tape includes a tape body, on which reflective lines are provided.

[0013] As a further improvement, the reflective tape is a woven tape, and the reflective line and the tape body are woven into one piece.

[0014] As a further improvement, the platform barrier assembly further includes anti-wear parts arranged at both ends, which are used to shield the outer surface of the barrier to prevent the barrier from directly contacting the through groove of the isolation connection device with friction.

[0015] As a further improvement, each barrier element is provided with an independent anti-wear element, and the anti-wear element is installed at the end of the barrier element.

[0016] As a further improvement, the same wear-proof member is installed at the ends of the group of barrier members to cover the group of barrier members.

[0017] As a further improvement, the wear-proof member is provided with a through hole for each barrier member to pass through.

[0018] As a further improvement, the wear-proof member includes two interlocking clamping plates, and the through hole is formed between the two clamping plates.

[0019] The beneficial effect is that the utility model is an improved invention. Specifically, under the action of the positioning bracket, the grouped barrier members can be stressed as a whole and have good wind resistance. Since the wide side of the barrier strip extends along the arrangement direction of the barrier strip, that is, the up and down direction, for waiting passengers, what they directly observe is the wide side, which obviously has a larger visible area. Compared with the prior art that uses round ropes as barrier members, under the condition of the same visible area, the barrier strip is lighter. At the same time, under the condition of the same volume (length multiplied by cross-sectional area), the barrier strip (rectangular cross-section) has better bending resistance than the round rope, and the barrier strip is not easy to sag and deform, and is not easy to swing back and forth as a whole.

[0020] To achieve the above objectives, the technical solution of the platform isolation protection system provided by the present invention is:

[0021] A platform isolation and protection system includes a plurality of isolation connecting devices arranged at intervals on the platform, a barrier assembly is connected between two adjacent isolation connecting devices, the barrier assembly includes a group of barrier members and a plurality of positioning brackets separating different barrier members in the same group, at least one barrier member in the group of barrier members is a barrier strip, the wide side of the barrier strip extends along the arrangement direction of the group of barrier members, and the barrier member on at least one of the adjacent two sides of the barrier strip is a barrier rope.

[0022] As a further improvement, the barrier members on both adjacent sides of the barrier strip are barrier ropes.

[0023] As a further improvement, at least one barrier tape is a reflective tape.

[0024] As a further improvement, the reflective tape includes a tape body, on which reflective lines are provided.

[0025] As a further improvement, the reflective tape is a woven tape, and the reflective line and the tape body are woven into one piece.

[0026] As a further improvement, the platform barrier assembly further includes anti-wear parts arranged at both ends, which are used to shield the outer surface of the barrier to prevent the barrier from directly contacting the through groove of the isolation connection device with friction.

[0027] As a further improvement, each barrier element is provided with an independent anti-wear element, and the anti-wear element is installed at the end of the barrier element.

[0028] As a further improvement, the same wear-proof member is installed at the ends of the group of barrier members to cover the group of barrier members.

[0029] As a further improvement, the wear-proof member is provided with a through hole for each barrier member to pass through.

[0030] As a further improvement, the wear-proof member includes two interlocking clamping plates, and the through hole is formed between the two clamping plates.

[0031] The beneficial effect is that the utility model is an improved invention. Specifically, under the action of the positioning bracket, the grouped barrier members can be stressed as a whole and have good wind resistance. Since the wide side of the barrier strip extends along the arrangement direction of the barrier strip, that is, the up and down direction, for waiting passengers, what they directly observe is the wide side, which obviously has a larger visible area. Compared with the prior art that uses round ropes as barrier members, under the condition of the same visible area, the barrier strip is lighter. At the same time, under the condition of the same volume (length multiplied by cross-sectional area), the barrier strip (rectangular cross-section) has better bending resistance than the round rope, and the barrier strip is not easy to sag and deform, and is not easy to swing back and forth as a whole.

[0044] In response to the problems identified in the background art above, the basic technical concept of the present invention is to provide a barrier assembly for a platform isolation and protection system that includes a barrier strip (flat strip). During use, the wide side of the barrier strip faces the front-to-back direction (corresponding to the direction in which passengers board and exit the train), or extends in the up-down direction, or in the direction in which the barrier strips are arranged, with the wide side of the barrier strip facing the passengers. Compared to the prior art solution of using round ropes to block waiting passengers, the barrier strip is lighter for the same visible area. Furthermore, the rectangular cross-section of the barrier strip is superior to that of a round rope for the same cross-sectional area. This ensures that the barrier strip has a larger visible area to attract the attention of waiting passengers, while also ensuring that the barrier strip remains straight and less prone to swinging back and forth.

[0045] The present invention is further described in detail below with reference to the embodiments.

[0046] Specific embodiments of the platform isolation protection system provided by the utility model:

[0047] like Figure 1 As shown, the platform isolation protection system includes a plurality of isolation connection devices arranged at intervals on the platform. The isolation connection device is a device used to connect the barrier components and drive the barrier components to rise (open the passenger boarding and alighting passage). Figure 1A lifting platform isolation and protection system is exemplified in the literature, which includes a plurality of lifting devices, and the lifting devices are equivalent to isolation connection devices. Specifically, the lifting device includes a fixed column 1 and a lifting column 2, and a barrier component for blocking waiting passengers is connected to the lifting column 2. The fixed column 1 is provided with a groove for the barrier component to pass through. The specific lifting process of the barrier component is consistent with the lifting process of the platform isolation and protection system using a round rope in the prior art, and will not be elaborated here. In addition to the lifting platform isolation and protection system including the fixed column 1 and the lifting column 2, for example, the barrier rope that can be lifted up and down in the lifting safety device provided in the invention patent application with application publication number CN113442951A is directly installed on the fixed column. At this time, the fixed column is equivalent to the isolation connection device, and the barrier component is connected to the fixed column, and the fixed column is provided with a groove for the barrier component to pass through.

[0048] like Figure 1 As shown, multiple (three or more) barrier assemblies are connected between two adjacent lifting devices, with the barrier assemblies spaced apart vertically. The specific number of barrier assemblies is determined by the height of the lifting device and the actual needs of the platform, and is not specifically limited here. Specifically, the barrier assembly includes a barrier strip 4 and multiple positioning brackets 3. The positioning brackets 3 are located outside the barrier strip 4 and are spaced apart along the length of the barrier assembly. Similarly, the number of positioning brackets 3 is determined by the distance between the two adjacent lifting devices and the actual needs of the platform, and is not specifically limited here.

[0049] In this embodiment, Figure 2 As shown, each set of barrier components includes two barrier strips 4 arranged in a vertical arrangement. Consistent with the prior art, there is also a ventilation gap between two adjacent barrier strips 4. The ventilation gap here refers to the gap for the airflow caused by the wind to pass through, so as to reduce the lateral wind force on the barrier components. In other embodiments, according to the actual needs of the platform, three or even more barrier strips 4 can be set in each set of barrier strips. Figure 1 Taking the lifting device shown in as an example, both ends of the barrier assembly are provided with connecting parts for connecting the lifting columns 2 in the lifting device. The specific connection method can be consistent with the existing technology and will not be described in detail here.

[0050] The main function of the positioning bracket 3 is to separate different barrier members in a group of barrier members. Specifically, the positioning bracket 3 is provided with a channel for a single barrier strip 4 to pass through. More specifically, the channel can be a circumferentially closed positioning perforation. The positioning perforation can correspond one-to-one with the barrier strip 4, or the number of positioning perforations can be more than the number of barrier strips 4. The barrier strip 4 passes through the positioning perforation. Under the action of the positioning bracket 3, two or more barrier strips 4 and the positioning bracket 3 form a force-bearing whole, ensuring that the barrier assembly can stably withstand wind force, and more than two barrier strips 4 will not cross-entangle. Of course, in other embodiments, in addition to the positioning perforations, a through groove (circumferentially non-closed) can also be provided on the positioning bracket 3, and the through groove can also specify the position of the barrier strip 4.

[0051] The positioning bracket 3 should be made of a material with a certain strength, such as an integrally injection-molded engineering plastic.

[0052] like Figure 1 and Figure 2 As shown, the wide side of the barrier strip 4 faces outwards, that is, Figure 1 The barrier strip 4 extends vertically, ensuring a larger visible area for waiting passengers, thereby attracting their attention. Compared to conventional round ropes, the barrier strip 4 significantly increases its visible area, given the same cross-sectional area. Furthermore, the rectangular cross-section of the barrier strip 4 (flat strip) significantly enhances its bending resistance compared to a circular cross-section, preventing the barrier strip 4 from sagging in the middle during use. Furthermore, compared to round ropes, the barrier strip 4 is also less susceptible to being cut or sheared, resulting in improved overall reliability.

[0053] Considering that some stations have a high number of late-arriving trains, at least one barrier strip 4 in each barrier assembly is reflective. Preferably, all barrier strips 4 in each barrier assembly are reflective. This allows the reflective strips to reflect light at night or in inclement weather, thereby attracting passengers' attention. Specifically, the reflective strips include a strip body with reflective threads 401 disposed thereon. Of course, for smaller stations with fewer trains arriving daily, most arriving during the day, reflective threads 401 may not be included in the barrier assemblies used at these stations, depending on their actual needs.

[0054] The barrier tape 4 can be made of a nylon tape produced through a weaving process. During the weaving process, reflective woven yarns made of a reflective material can be integrally woven with the barrier tape 4. The reflective woven yarns form reflective threads 401. This form of reflective threads 401 is more reliable and less likely to fall off the barrier tape 4. In other embodiments, in addition to the integral weaving process, thin threads (or strips) coated with a reflective coating can also be provided on the surface of the formed tape. Of course, the reflective tape can also be entirely reflective, for example, the barrier tape can be woven entirely with reflective woven yarns, or the entire surface of the barrier tape can be coated with a reflective coating.

[0055] In order to avoid direct frictional contact between the barrier assembly and the through groove of the isolation connection device and to increase the service life of the barrier assembly, the barrier assembly in this embodiment further includes anti-wear parts 5 provided at both ends of the barrier strip 4. The anti-wear parts 5 serve to shield the outer surface of the barrier strip 4. Figure 3 As shown, specifically, the anti-wear parts 5 should be provided at both ends of the barrier strip 4 .

[0056] Preferably, each barrier strip 4 arranged in groups up and down is shielded by the same anti-wear member 5, that is, the same anti-wear member 5 is installed at the end of the group of barrier strips 4. In this way, for the same group of barrier strips 4, only one anti-wear member 5 is required at one end, which is convenient for installation. Of course, in other embodiments, independent anti-wear members 5 can also be installed on the periphery of each barrier strip 4, that is, the barrier members and the anti-wear members 5 are correspondingly arranged. For details, please refer to Figure 4 , which can also play an anti-wear effect. In addition, if Figure 5 As shown, for the barrier strip 4, in addition to providing a square wear-proof member, a circular wear-proof member can also be provided.

[0057] On the basis of installing the same anti-wear part 5 on each barrier strip 4, as shown in FIG. Figure 6 and Figure 7 As shown, the anti-wear member 5 can be provided with a through hole for a single barrier strip 4 to pass through. When a single barrier strip 4 passes through the through hole, the anti-wear member 5 can also play a role in strengthening the barrier assembly. The anti-wear member 5 is equivalent to a positioning bracket added to the end of the barrier assembly. Of course, the basic function of the anti-wear member is to prevent wear. In other embodiments, the anti-wear member can also be provided with a long hole. In this case, the anti-wear member can be a collar, and all the barrier strips 4 in the same set of barrier assemblies can pass through the long hole. Or, as Figure 8 As shown, the anti-wear part 5 can also be a U-shaped material formed by bending or integral injection molding, with a long groove inside, and the barrier strip 4 passes through the long groove of the anti-wear part 5.

[0058] In addition, if Figure 6 and Figure 7As shown, the anti-wear member 5 preferably comprises two plywood panels, which can be fastened together to enclose the aforementioned through-hole. During installation, the two plywood panels are clamped around the periphery of the barrier strip 4 to shield the outer surface of the barrier strip 4. More preferably, the two plywood panels can be bolted together during installation. This facilitates both processing and adjusting the tightness of the plywood panels to ensure they can compress the barrier strip 4. Of course, in other embodiments, the anti-wear member can also be an integrally manufactured anti-wear sleeve (collar) that is directly attached to the periphery of the barrier strip 4 during installation.

[0059] Regardless of the form of anti-wear parts, preferably, the anti-wear parts can be made of stainless steel or wear-resistant plastic materials commonly used in engineering. In this way, while ensuring higher hardness, they can be more adaptable to relatively humid outdoor environments and are not easy to rust.

[0060] In other embodiments, only some of the barrier elements in the platform barrier assembly may be barrier strips 4, and the other barrier elements may be barrier ropes. Specifically, the barrier strips 4 may be arranged at the bottom, top, or center. Figure 9 For example, three barriers are grouped together, namely, a barrier strip 4 and a barrier rope 6 (which can be a round rope in the prior art). The barrier rope 6 is located on both sides of the barrier strip 4, that is, the barrier strip 4 is arranged in the center. In this case, the barrier strip 4 can also increase the visible area and enhance the overall strength of the barrier assembly. At the same time, this symmetrical structure also has a higher aesthetic appeal. Correspondingly, Figure 10 As shown, the wear protection member 5 also needs to be flexibly adjusted to cover the barrier rope 6 and the barrier belt 4.

[0061] Specific embodiments of the platform barrier assembly in the present utility model:

[0062] The embodiment of the platform barrier component is the barrier component described in the embodiment of the platform isolation and protection system described above, and will not be described in detail here.

[0063] Finally, it should be noted that the above description is merely 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 aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
