Description

Technical Field

[0001] The utility model belongs to the technical field of general platform configuration including passenger protection equipment, and in particular relates to a retractable platform barrier component and a platform protection device. Background Art

[0002] The existing railway platforms in my country are generally open platforms. Some passengers have weak safety awareness and often walk across the platform safety line. Once a passenger accidentally falls from the platform, it may cause a serious safety accident. Therefore, it is necessary to configure protective devices on the platform to prevent passengers from crossing the safety line.

[0003] Unlike subway platform protection doors, the stop positions of high-speed trains or ordinary passenger trains of different numbers are not exactly the same, which requires the platform protection device to open a wider passenger passage as much as possible when opening the door. For this reason, a lifting platform protection device has appeared in the prior art. For example, the patent with the authorization announcement number CN211280998U of the applicant provides a lifting platform protection device. When the protection device is installed on the platform, the overall appearance is as disclosed in the patent with the authorization announcement number CN305782671S of the applicant. The protection device includes a plurality of driving columns, each of which is fixed on the platform at intervals. A barrier member that plays a role in protecting and blocking passengers is connected between two adjacent driving columns. The barrier member extends horizontally (laterally), and multiple groups are arranged at intervals up and down. A driving device that drives the barrier member to move up and down and to retract and expand is provided on the driving column.

[0004] The platform protection device has a protection state and an open state during use. In the protection state, each barrier is located at a lower position, and the distance between the upper and lower adjacent groups of barrier is the farthest, forming a barrier guardrail structure. When the train stops at the platform and passengers get on and off, the drive device can drive the barrier to rise from the bottom to the top. During the rising process, each barrier moves upward, and the upper and lower adjacent groups of barrier are close to each other, so that the lowermost barrier rises to a height that satisfies the normal passage of passengers, thereby opening the passage for passengers to get on and off the train, that is, the open state. In the open state, the distance between the upper and lower adjacent groups of barrier is the shortest.

[0005] In actual application on the platform, the applicant found that only horizontally (transversely) extending barriers still have the following two problems or aspects that need to be improved: First, the overall strength of the guardrail structure formed by the barriers is weak, and the protective effect is insufficient. If a passenger intends to climb over the platform, the passenger may manually pry apart two adjacent groups of barriers and drill through the space between the two adjacent groups of barriers, so the barriers are difficult to play a good role in blocking passengers. Moreover, if a passenger accidentally falls, it is also possible to open two adjacent groups of barriers and drill through the space between the two adjacent groups of barriers. Second, the barriers are generally woven with nylon or high molecular polyethylene materials. The outdoor platform environment is poor. Affected by factors such as strong winds, the barriers are also prone to friction with the drive columns when moving. When used for a long time, the barriers may be cut off and blown to dangerous areas by the wind, such as rails or contact lines, which may bring potential accidents and insufficient safety. Utility Model Content

[0006] The utility model also aims to provide a retractable platform barrier assembly to solve the technical problem that the platform protection device using only horizontal barrier members in the prior art has insufficient protection effect and safety.

[0012] As a further improvement, the gland is connected to the clamping plate by screws or buckles.

[0013] As a further improvement, the connection positions of the vertical blocking member and each horizontal blocking member are connected by a clamping bracket.

[0014] The beneficial effect is that the utility model improves the barrier components of the prior art that serve to block passengers. Specifically, in addition to the transverse barrier members extending laterally, the utility model adds vertical barrier members, and the vertical barrier members are connected to the transverse barrier members, forming a mesh structure with higher strength as a whole. Since the vertical barrier members are flexible barrier members, in actual use, under the driving action of the driving column, two adjacent groups of transverse barrier members can still approach and move away from each other.

Different from the prior art, the barrier component in the utility model is a mesh structure with higher strength as a whole, which has a better protective effect.

[0033] Protection effect and safety are key factors to be considered when developing platform protection devices. In the prior art, the horizontal (lateral) extending barrier connected between two adjacent driving columns has room for improvement in both protection effect and safety. To this end, the basic technical concept of the utility model is to provide a platform barrier assembly that can be used for platform protection devices. Specifically, in addition to the horizontally extending lateral barrier, multiple groups of vertically extending vertical barrier are added. The lateral barrier and the vertical barrier are connected, and there are multiple connection intersection positions. In addition, the vertical barrier is a flexible barrier, such as a protective rope or a protective belt, so that the platform barrier assembly formed can be folded and stretched up and down. Different from the prior art, the barrier assembly in the utility model has a higher overall strength, so that the protection effect of the platform protection device is improved. In addition, during long-term use, even if a group of lateral barriers is cut off, under the connection and maintenance of the vertical barrier, the broken barrier is not easy to swing randomly, thereby improving safety.

[0034] The present invention is further described in detail below in conjunction with the embodiments.

[0035] The specific embodiment of the platform protection device provided by the utility model is as follows:

[0036] The platform protection device provided in this embodiment is as follows: Figure 1As shown, the platform protection device includes a plurality of driving columns which are arranged at intervals on the platform when in use, and a platform barrier assembly (hereinafter referred to as the barrier assembly) is connected between two adjacent driving columns, and the left and right ends of the barrier assembly are respectively connected to the driving columns. As a feasible implementation method, the driving column can use a lifting driving column of the prior art, including a fixed column 1 fixed on the platform and a lifting column 2 which is lifted up and down relative to the fixed column 1. The transverse barrier 3 in the barrier assembly is connected to the lifting column 2, and a linkage mechanism is provided between the lifting column 2 and the transverse barrier 3. When the lifting column 2 moves up and down, the linkage mechanism can synchronously drive the transverse barrier 3 to move, thereby opening a passage for passengers to get on and off the train. Figure 1 The platform protection device is shown in the protection state, and the distance between two adjacent groups of transverse barriers 3 is the farthest. When passengers need to get on or off the train, the lifting column 2 moves upward, and each transverse barrier 3 moves upward as a whole, and two adjacent groups of transverse barriers 3 are close to each other, and the platform protection device is in the open state.

[0037] Specifically, for the barrier component, if Figure 1 As shown, it includes multiple groups of transverse barriers 3 and vertical barriers 4. The transverse barriers 3 are arranged in the vertical direction, and the vertical barriers 4 are arranged in the horizontal direction. The transverse barriers 3 and the vertical barriers 4 are connected, and there are multiple intersection positions of the connection. The vertical barriers 4 are flexible barriers. When two adjacent groups of transverse barriers 3 move closer to each other, the vertical barriers 4 can bend and deform adaptively without affecting the normal operation of the platform protection device.

[0038] Based on the above structure, the horizontal barrier 3 and the vertical barrier 4 in the barrier assembly are connected and matched with each other to form a high-strength mesh structure. Figure 1 As shown, compared with the solution with only the transverse barrier 3 in the prior art, under the action of the vertical barrier 4, in the protective state, the distance between two adjacent groups of transverse barrier 3 is not easily opened and expanded, and the protective effect is better. At the same time, during long-term use, even if one group of transverse barrier 3 is cut off by the driving column, under the action of the transverse connection and maintenance of the vertical barrier 4, the cut transverse barrier 3 is not easy to swing with the wind, and the safety is higher.

[0039] As a method for convenient connection and manufacturing and a more integrated implementation, Figure 1 As shown, the length of the vertical barrier 4 matches the distance between the two groups of transverse barrier 3 that are the farthest apart in the protective state, and the same group of vertical barrier 4 is connected to all transverse barrier assemblies. Of course, in other embodiments, the vertical barrier 4 may also be a "short section" structure, where each section of the vertical barrier matches the distance between two adjacent groups of transverse barrier assemblies 3 in the protective state, and two adjacent groups of transverse barrier assemblies 3 are connected to a section of vertically extending barrier assemblies, and finally form an integral vertical barrier assemblies.

[0040] like Figure 1 As shown, the vertical barrier and the uppermost and lowermost transverse barrier are connected at the intersection of the vertical barrier and the uppermost and lowermost transverse barrier by a clamping bracket 5. Figure 2-Figure 5 As shown, the clamping bracket 5 includes a clamping plate 503 and a pressure cover 505. The clamping plate 503 is provided with a transverse receiving groove 501 and a vertical receiving groove 502. The transverse receiving groove 501 is used to receive the transverse blocking member 3, and the vertical receiving groove 502 is used to receive the vertical blocking member 4. The transverse receiving groove 501 and the vertical receiving groove 502 are cross-connected. The pressure cover 505 is connected to the clamping plate 503 through a detachable connecting member. After the pressure cover 505 is installed on the clamping plate 503, the openings of the transverse receiving groove 501 and the vertical receiving groove 502 can be blocked, and the transverse blocking member 3 in the transverse receiving groove 501 and the vertical blocking member 4 in the vertical receiving groove 502 can be pressed. In other words, the clamping bracket 5 is actually a bracket structure that is interlocked (clamped) at the intersection of the transverse barrier and the vertical barrier. This structure is convenient for manufacturing the barrier assembly. In addition, the connection strength at the intersection of the barrier assembly is higher. During use, as the barrier assembly is folded and unfolded, the transverse barrier 3 and the vertical barrier 4 are not easy to loosen. When an independent clamping bracket 5 is used for connection, the transverse barrier 3 and the vertical barrier 4 do not need to be braided and wound, which is convenient for connection. The reliability of the clamping bracket 5 is also better than that of the general binding rope used to bind the barrier. In the case of long-term use, the intersection is not prone to loosening.

[0041] For the clamping bracket 5, the functions of the horizontal receiving groove 501 and the vertical receiving groove 502 are analyzed to know that in order to accommodate the horizontal blocking member and the vertical blocking member, in fact, in other embodiments, the horizontal receiving groove and the vertical receiving groove can also be set on the pressure cover 505. Of course, the horizontal receiving groove and the vertical receiving groove can also be set on the pressure cover 505 and the clamping plate 503, such as Figure 6 As shown, at this time, transverse accommodating grooves and vertical accommodating grooves can also be opened at the positions of the corresponding transverse accommodating grooves and vertical accommodating grooves on the pressure cover 505 and the clamping plate 503. Similarly, the overall size of the integral transverse accommodating grooves and vertical accommodating grooves formed at this time satisfies the requirement that the transverse barriers and vertical barriers therein are fastened by the pressure cover and the clamping plate.

[0042] More specifically, the gland 505 is connected to the clamping plate 503 by screws, that is, the above-mentioned detachable connecting member is a screw. In this case, a screw hole can be set on the clamping plate 503, and a through hole for the screw to pass through can be set on the gland 505. The screw passes through the gland 505 and is connected to the clamping plate 503, so that the gland 505 and the clamping plate 503 are compressed. Of course, the detachable connection structure can also be in other forms. For example, an elastic buckle can be set on the gland 505, and a slot that can be engaged with the buckle can be set on the clamping plate 503. When disassembly is required, the gland 505 can be pulled outward to withdraw the buckle from the slot. It is not difficult to understand that the screw connection method is convenient for connection, and by adjusting the pre-tightening force of the screw, it can also ensure that the horizontal barrier 3 and the vertical barrier 4 are reliably compressed.

[0043] It should be noted that, in the above-mentioned transverse barrier 3 and vertical barrier 4, both the transverse barrier 3 and the vertical barrier 4 may include more than one flexible barrier, and the barrier may be a barrier rope 6 or a barrier belt 7. Then, correspondingly, both the transverse receiving groove 501 and the vertical receiving groove 502 should be configured as branch receiving grooves corresponding to each barrier. There are three situations here. One is that the transverse barrier 3 has only one barrier, and the vertical barrier 4 includes two (or more) barriers. Another is that the vertical barrier 4 includes two (or more) barriers. The last one is that both the transverse barrier 3 and the vertical barrier 4 include two (or more) barriers. Figure 7 and Figure 8 As shown, both the transverse barrier 3 and the vertical barrier 4 can be configured as a combined barrier including two barrier ropes 6 and a barrier belt 7. Correspondingly, the transverse receiving groove 501 and the vertical receiving groove 502 also include branch receiving grooves for each barrier rope 6 or barrier belt 7 to pass through. With this design, under the action of the clamping bracket 5, a higher strength combined barrier assembly can be formed, and the visual width of each group of barriers will be wider, which is convenient for passengers to observe and warn passengers to pay attention to safety. In addition, since the barriers are arranged at intervals, when used on the platform, even in windy weather, the grouped transverse barriers or vertical barriers will not "take off", avoiding the wind from causing the barrier assembly to swing.

[0044] It should also be noted that, for the vertical barrier 4, in addition to being connected to the uppermost and lowermost transverse barrier 3 by means of the clamping bracket 5, the transverse barrier 3 between the uppermost and lowermost transverse barrier 3 can also be connected by means of the clamping bracket 5, that is, the connection positions of the vertical barrier 4 and all the transverse barrier 3 are connected by means of the clamping bracket 5. However, in other embodiments, the intersection connection positions of the vertical barrier 4 and the transverse barrier 3 between the uppermost and lowermost transverse barrier 3 can also be connected by means of the retaining bracket 8.

[0045] Analysis of the structure of the barrier assembly shows that in order to prevent the two ends of the vertical barrier 4 from being separated from the uppermost and lowermost transverse barriers 3, respectively, the use of a clamping bracket 5 for connection has a better clamping effect and a more reliable connection. However, for the position between the uppermost and lowermost transverse barriers 3, that is, the intersection position of the middle position, when the two ends of the vertical barrier 4 are already reliably connected, the basic function of the retaining bracket 8 used at the middle position is to keep the vertical barrier 4 and the transverse barrier 3 at the corresponding determined positions. Therefore, the basic structure of the retaining bracket 8 is to have a transverse channel and a vertical channel, the transverse barrier 3 passes through the transverse channel, and the vertical barrier 4 passes through the vertical channel, then the retaining bracket 8 can keep the transverse barrier 3 and the vertical barrier 4 passing through it at a determined position. Specifically, the structure of the retaining bracket 8 can be a split structure similar to the above-mentioned clamping bracket 5, that is, it includes a plate-shaped retaining plate and a cover detachably connected to the retaining plate, and the retaining plate is provided with a receiving groove for accommodating the horizontal blocking member 3 and the vertical blocking member 4. After the cover is installed on the retaining plate, the opening of the receiving groove is closed to form a horizontal channel and a vertical channel. Alternatively, the retaining bracket 8 can be an integrated block structure or a plate structure, and the horizontal channel and the vertical channel can be formed by closed perforations on the block structure or the plate structure, and the perforations meet the requirements of the horizontal blocking member 3 and the vertical blocking member 4 passing through.
