Description

Technical Field

[0001] The utility model belongs to the technical field of general platform configuration including passenger protection equipment, and particularly relates to a lifting device with a display screen and a platform protection system. Background Art

[0002] The existing railway platforms in China are generally open platforms. Some passengers have weak safety awareness, and the phenomenon of crossing the platform safety line and walking around at will often occurs. Once a passenger accidentally falls from the platform, it may cause serious safety accidents. Therefore, it is necessary to configure a protection device on the platform that can block passengers from crossing the safety line.

[0003] The invention patent with the authorization announcement number of CN110641482B of the applicant provides a lifting safety door (lifting platform protection system) that displays train car numbers and boarding guidance information at railway passenger stations. The safety door includes a plurality of lifting devices for being arranged at intervals at the edge of the platform. The lifting device includes a fixed column and a lifting column that can move up and down along the fixed column within a set lead. A blocking member is connected between the lifting columns of two adjacent lifting devices, and the blocking member can be a blocking belt. Specifically, a plurality of sliders that can move up and down along the lifting column are provided on the lifting column, and the blocking member is connected to the sliders. When the lifting column rises, it can drive the slider to rise, and then drive the blocking member to rise, opening the passage for passengers to get on and off the train; when the lifting column descends, it can drive the slider to descend, and then drive the blocking member to descend, blocking passengers from crossing the safety line and playing a protective role. In addition, in order to facilitate passengers to find the target train number and car, the above safety door is also configured with a display screen on the lifting device. Specifically, the display screen is installed on one side of the fixed column facing the waiting passengers. The lifting device is configured with a communication unit that can be communicatively connected to the train control center to obtain train information, and the display screen can display train information such as the boarding train number, car number, departure time, etc.

[0004] The above safety door has been successfully applied in many high-speed railway stations in China, greatly improving the waiting safety. During actual application, the applicant found that the position of the display screen is relatively low. The passengers who have just completed ticket checking and entered the platform are far away from the lifting device, and the display screen is easily blocked by the waiting passengers already on the platform, with a relatively small actual visible range. Passengers often have to walk near the display screen to see the train information, which is still not convenient for guiding passengers to quickly find the target train number and car. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a lifting device with a display screen to solve the technical problem that the effect of guiding passengers to find the target train number and car in the existing platform protection system is insufficient. The purpose of the utility model is also to provide a platform protection system to solve the same technical problem.

[0035] In order to facilitate guiding waiting passengers to find the target train number and carriage, the basic technical concept of the present utility model is to install a display on the top of the lifting column of the lifting device used in the platform protection system to display train information. Setting the display on the top of the lifting column can directly increase the position of the display on the one hand, and on the other hand, the display can also rise to a higher position along with the lifting column, so that it is convenient for passengers to observe the information displayed on the display, and the display is not easily blocked by passengers, thereby better guiding passengers.

[0036] The following further describes the present utility model in detail with reference to embodiments and drawings.

[0037] Specific embodiments of the lifting device with a display screen provided by the present utility model:

[0038] The lifting device with a display screen provided in this embodiment (hereinafter referred to as the lifting device) can be used in a platform protection system. When in use, according to the needs of the platform, multiple lifting devices can be arranged at intervals on the edge of the platform, and a barrier is connected between adjacent two lifting devices, such as a barrier belt (flat belt) and / or a barrier rope (round rope). The lifting device includes a fixed column 1 and a lifting column 2. Consistent with the prior art, the fixed column 1 is used to be fixed on the platform ground, and the lifting column 2 can move up and down along the fixed column 1 within a set lead. The top of the fixed column 1 has an opening for one end of the lifting column 2 to pass through. Naturally, a lifting drive device for driving the lifting column 2 to move up and down is provided between the fixed column 1 and the lifting column 2, and the installation forms of the lifting drive device can all adopt the prior art, which will not be specifically described here. The barrier is connected to the lifting columns 2 of adjacent two lifting devices. As Figure 1 and Figure 2 shown, the barrier can pass through the through slot 101 on the side of the fixed column 1. In addition, a power distribution system 102 for supplying power to each electrical component is also installed on the fixed column 1. As Figure 3 shown, the power distribution system 102 includes a distribution box installed on the fixed column 1 and switches, circuits, etc. located in the distribution box. The power supply system of the platform can be electrically connected to the power distribution system 102 through underground buried wires to supply power to the lifting device.

[0039] Different from the prior art, in this embodiment, as Figure 3 shown, a display 301 is installed at the top of the lifting column 2. A power line is connected between the display 301 and the power distribution system 102, and the power distribution system 102 can supply power to the display 301 through the power line. The display 301 includes a display screen. Specifically, the display 301 is installed on one side of the top of the lifting column facing the inner side of the platform, that is, the side Figure 3 in the A direction of Figure 3 , that is, the side facing away from the train. Of course, the display 301 also includes a control module for controlling the display content of the display screen. In order to play a role in guiding waiting passengers to find the train, the content displayed on the display screen should at least include the train information of the current platform, such as train number information, the car number of the current position, and guiding arrows for the car arrangement order, etc.

[0040] Compared with the prior art, in this embodiment, a display 301 is configured at the top of the lifting column 2. As Figure 1 shown, the display 301 can be in a relatively high position, not easily blocked, and is convenient for passengers to observe the effective information on the display screen. As Figure 2 shown, after the lifting column 2 rises, the display 301 can move to a higher position along with the lifting column 2, so that the display 301 will be even less likely to be blocked, which is convenient for passengers at a distant position to observe, thus achieving a better effect of guiding passengers.

[0041] In fact, there are waiting passengers at all positions of the platform. To facilitate passengers standing on the side of the lifting device to observe train information, in other embodiments, displays 301 can also be installed on the sides (left and right sides) adjacent to one side of the inner side of the platform at the top of the lifting column. In this way, train information can be displayed on the display screen in different directions at the top of the lifting column, facilitating passengers in different directions on the platform to see the train information in a timely manner.

[0042] It should be noted that according to different platform requirements, in some embodiments, the display can also be installed only on the side facing the inner side of the platform, or only on a certain side adjacent to the side facing the inner side of the platform.

[0043] As a way to obtain train information, a communication unit can be configured in the control module. When the lifting device is installed on the platform, the communication unit can communicate with the train control center (TCC) and obtain train information online from the train control center. In this way, the train information can be obtained in real time and accurately, which is relatively flexible.

[0044] Considering that there are many people waiting on the platform and the wireless signals are complex, in order to make the communication signal transmission more stable, the communication unit preferably obtains train information by means of a wired connection, that is, the communication unit is connected to the server through a communication line. Specifically, a relay switch can be integrated in the power distribution system 102, and the communication unit is communicatively connected to the relay switch through a communication line.

[0045] In fact, according to the arranged train timetable, the arrival time and arrival position of the train can be basically accurately determined. For example, existing platforms use floor markers of different colors to indicate train information. Therefore, in other embodiments, the control module may not be communicatively connected to the train control center, but a storage unit can be configured in the control module, and different information is manually pre-stored in the storage unit, and the display content of the display screen is manually switched during actual use. Naturally, in this case, there is no need for a communication line either.

[0046] Of course, in other embodiments, the communication unit configured in the control module may also obtain train information without passing through the train control center, that is, the communication unit is not connected to the server of the power distribution system. For example, an operation tablet can be configured for the platform passenger service staff, and the communication unit is communicatively connected to the operation tablet, and the passenger service staff inputs train information through the operation tablet.

[0047] To protect the communication line and the power supply line and prevent the communication line and the power distribution line from being disorderly wound or damaged by the lifting column 2 during the movement process, in this embodiment, a cable carrier 4 is preferably used to protect the power distribution line and the communication line. As a feasible embodiment, such as Figure 3As shown in the figure, a drag chain 4 can be adopted to protect the power distribution line and communication line. One end of the drag chain 4 is connected to the lifting column 2, and the other end is connected to the fixed column 1. The power line and communication line are installed inside the drag chain 4. It can be understood that whether there is a communication line or not, in order to protect the power line, the drag chain 4 can be set. The specific form of the drag chain 4 is not specifically limited in this embodiment, and the material can be selected as nylon.

[0048] In addition, in this embodiment, in addition to the column body that directly guides and cooperates with the fixed column 1, the lifting column 2 further includes a housing installed on the column body. No matter which form of the drag chain 4 is adopted, one end of the drag chain 4 can be connected to the housing, that is, the position where the drag chain 4 is connected to the lifting column is actually located at the housing. Specifically, as Figure 3 shown, the drag chain 4 can be connected to the housing through the fixing bracket 5 and screws. Connecting the drag chain 4 and the housing can prevent the drag chain 4 from interfering with the normal up and down movement of the column body, and at the same time, under the shielding effect of the housing, the lifting column 2 is more beautiful after rising.

[0049] In order to make the lifting device structure more compact and avoid the lifting device from being too wide front and back, preferably, the drag chain can be arranged on the left or right side of the lifting column. Of course, in other embodiments, it is not excluded that the drag chain is arranged on the front or right side of the lifting column.

[0050] The platform belongs to an environment that is open on all sides. In bad weather, wind and rain are likely to cause dust and rainwater to enter the inside of the fixed column through the opening of the fixed column. To solve this problem, a protective cap 3 is further provided at the top of the lifting column. The size of the protective cap 3 is larger than the opening at the top of the fixed column. When the lifting column is in the low position, the protective cap 3 can be attached to the top of the fixed column 1 to close the opening of the fixed column 1, playing a basic role in dust and waterproof protection. The shape of the protective cap 3 is not specifically limited in this embodiment, and it can be Figures 1 - 3 the square shown in the figure, Figure 4 and Figure 5 and Figure 6 and Figure 7 the special shape in the figure. The display is installed on the protective cap 3. In this way, the reliable installation of the display 301 is realized without affecting the normal protection performance of the protective cap 3, and the protective cap 3 can also play a relatively basic role in protecting the display 301. Of course, in other embodiments, the display 301 can also be directly installed on a certain side surface of the lifting column 2. At this time, basic protection treatment can be carried out on the display 301.

[0051] Furthermore, the size of the protective cap 3 is relatively large, and it includes an installation cavity. The display 301 is embedded in the installation cavity. Except for one side of the display screen, the other parts of the display 301 can be protected by the protective cap 3. In this way, the protective cap 3 can play an all-round protection role for the display 301 and improve the use reliability of the display 301.

[0052] It should also be noted that the display 301 installed at the top of the lifting column 2 can basically meet the needs of guiding passengers. Therefore, it is not necessary to install a display on the fixed column. However, in order to display more information (including train information and advertisement information), in some embodiments, a display can also be installed on the fixed column 1.

[0053] Specific embodiments of the platform protection system in the present utility model:

[0054] The platform protection system includes a plurality of lifting devices for being arranged at intervals on the platform edge, and at least one lifting device is the lifting device with a display configured at the top of the lifting column as described in the embodiments of the above-mentioned lifting device. When there is a display configured at the top of the lifting column of only one lifting device, this lifting device can be arranged at the position of the passenger escalator on the platform.

[0055] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still make modifications to the technical solutions described in the foregoing embodiments without creative efforts, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
