Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lifting type platform door, and concretely relates to a hidden intelligent lifting type platform door. BACKGROUND

[0002] In recent years, sudden accidents have occurred many times due to passengers and goods falling off the platform, which not only brings personal safety hazards and inconvenience to passengers, but also causes great negative impact on station operation work. Some stations have gradually tried to use platform safety door (shield door) systems to separate the platform waiting area and the train track area, avoid the strong wind pressure generated when the train passes through the station to bring the danger of being blown and sucked to the waiting passengers, avoid the phenomenon of passengers looking around and running with the train, avoid the danger of waiting personnel and goods falling off the platform track, effectively reduce the frequency of train accidents, at the same time, also reduce a large number of platform receiving personnel, improve the service level and overall image of national railway stations, and also improve the travel safety and comfort experience of passengers.

[0003] Chinese patent document CN112796611A discloses a lifting type platform door system, which comprises a control unit, a communication unit, and a plurality of lifting door units arranged side by side. The lifting door units are arranged in a foundation pit located at the edge of the platform and are pre-set along the length direction. The control unit controls the lifting action of each lifting door unit through the communication unit. The lifting door unit comprises a mounting frame fixedly arranged in the foundation pit, a lifting door plate vertically arranged on the mounting frame through a lifting drive unit, and a self-locking mechanism for locking the lifting door plate in place on the mounting frame. The top of the mounting frame is provided with an openable and closable horizontal cover plate.

[0037] In one embodiment, the pneumatic lifting assembly 11 comprises:

[0038] The lifting chamber 16 is located in the bottom fixed seat 10 and is connected to the top end of the bottom fixed seat 10.

[0039] The guide rail fixed base 17 is fixedly installed at the bottom of the lifting chamber 16.

[0040] The lifting main shaft 18 and the carbon fiber telescopic barrier group 21, the bottom ends of the two lifting main shafts 18 are respectively installed on the main shaft support base 19, the main shaft support base 19 is installed on the guide rail fixed base 17, the top end of the lifting main shaft 18 is connected with the integral cross beam 12, the main shaft protection sleeve 20 is installed at the bottom end of the bottom fixed seat 10, passes through the guide rail fixed base 17 and is connected to the main shaft support base 19 in the installation flange plate, and the carbon fiber telescopic barrier group 21 is connected between the guide rail fixed base 17 and the integral cross beam 12.

[0041] The working principle and beneficial effects of the above technical scheme are:

[0042] When the integral cross beam 12 sinks on the bottom fixed seat 10, the lifting main shaft 18 sinks into the lifting chamber 16 synchronously with the integral cross beam 12, and the carbon fiber telescopic barrier group 21 shrinks on the guide rail fixed base 17. After the carbon fiber telescopic barrier group 21 is stretched, it cooperates with the lifting main shaft 18 to isolate the passengers.

[0043] In one embodiment, the number of driving cylinders 22 is single, the driving cylinder 22 comprises a pneumatic push rod 23, a cylinder barrel 24, and a cylinder piston 25, the cylinder piston 25 is located in the cylinder barrel 24, the pneumatic push rod 23 extends into the cylinder barrel 24 from the top end of the cylinder barrel 24 and is connected with the cylinder piston 25, the pneumatic push rod 23 is located in one of the carbon fiber telescopic barriers of the carbon fiber telescopic barrier group 21, a cylinder assembly protection sleeve 26 is installed at the bottom end of the bottom fixed seat 10 and is connected to the guide rail fixed base 17, and the cylinder barrel 24 is located in the cylinder assembly protection sleeve 26.

[0044] When the number of driving cylinders 22 is a pair, the driving cylinder 22 comprises a pneumatic push rod 23, a cylinder barrel 24, and a cylinder piston 25, the cylinder piston 25 is located in the cylinder barrel 24, an upper end cover is installed at the top end of the cylinder barrel 24, a lower end cover 33 is installed at the bottom end of the cylinder barrel 24, an air inlet 35 and an air outlet 36 are reserved on the lower end cover 33, the pneumatic push rod 23 extends into the cylinder barrel 24 from the lower end cover 33 and is connected with the cylinder piston 25, the cylinder barrel 24 is located in the lifting main shaft 18, and the pneumatic push rod 23 is located in the main shaft protection sleeve 20.

[0045] The top end of the main shaft support base 19 is provided with a linear bearing 32, the bottom end of the lifting main shaft 18 penetrates the linear bearing 32, a spiral air pipe 34 is arranged on the linear bearing 32, and the spiral air pipe 34 is connected with an air inlet 35.

[0046] The working principle and beneficial effects of the technical scheme are as follows:

[0047] The working principle and beneficial effects of the technical scheme are as follows:

[0048] The utility model discloses a hidden intelligent lifting type platform door, and is divided into single cylinder type and double cylinder type according to the number of driving cylinders 22, like Figure 4 and Figure 9 As shown in the drawings, the single cylinder type lifting type platform door section view and the double cylinder type lifting type platform door section view are respectively shown, and the difference between the two lies in that different numbers of driving cylinders 22 are matched.

[0049] When the single cylinder type is used, the cylinder assembly protection sleeve pipe 26 buried in the bottom end of the bottom fixed seat 10 is used for accommodating the cylinder barrel 24 and the pneumatic push rod 23 retracted into the cylinder barrel 24, and because the pneumatic push rod 23 is located in one of the carbon fiber telescopic barriers (as shown in Figure 4 The middle one of the carbon fiber telescopic barriers). When the pneumatic element works, the electromagnetic valve cooperates to send the gas source generated by the air pump into the cylinder barrel 24 through the air pipe, so that when the pneumatic push rod 23 is retracted into the cylinder barrel 24, the lifting main shaft 18 is synchronously sunken with the integrated cross beam 12, the integrated cross beam 12 is located in the accommodation port 14, the lifting main shaft 18 is retracted into the main shaft protection sleeve pipe 20 through the main shaft support base 19 to protect the lifting main shaft 18, and the effect of preventing corrosion and foreign matter from being stuck is achieved.

[0050] In the double-cylinder type, two driving cylinders 22 are respectively matched with two main shaft protection sleeves 20 to save space. Specifically, the cylinder piston 25 divides the cylinder barrel 24 into two independent chambers, the lower intake chamber 37 near the lower end cover 33, and the upper exhaust chamber 38 near the upper end cover. The air inlet 35 is communicated with the lower intake chamber 37, and the cylinder barrel 24 and the lifting main shaft 18 are left with a sealed interlayer 39. The air outlet 36 is communicated with the sealed interlayer 39, and the upper end cover near the cylinder barrel 24 end is reserved for the communication groove for communicating the sealed interlayer 39 and the upper exhaust chamber 38. The pneumatic element works, and the electromagnetic valve cooperates to send the gas source generated by the air pump into the air inlet 35 and the lower intake chamber 37 communicated with the air inlet 35. The gas pressure in the lower intake chamber 37 becomes larger, the cylinder piston 25 connected with the pneumatic push rod 23 slides in the cylinder barrel 24 to the direction close to the upper end cover, the cylinder barrel 24 drives the lifting main shaft 18 to sink along the linear bearing 32, the spiral air pipe 34 is stretched, the lifting main shaft 18 drives the cylinder barrel 24 to enter the main shaft protection sleeve 20 through the main shaft support base 19 to protect the lifting main shaft 18, and play a role in preventing corrosion and foreign matter jam. The integrated beam 12 connected with the lifting main shaft 18 is located in the storage opening 14, and the carbon fiber telescopic barrier group 21 is retracted. When the integrated beam 12 needs to be lifted, the pneumatic element works, and the electromagnetic valve cooperates to send the gas source generated by the air pump into the air outlet 36 and the sealed interlayer 39 communicated with the air outlet 36, and from the communication groove communicated with the sealed interlayer 39 into the upper exhaust chamber 38. The gas pressure in the upper exhaust chamber 38 becomes larger, the cylinder piston 25 connected with the pneumatic push rod 23 slides in the cylinder barrel 24 to the direction close to the lower end cover 35, the cylinder barrel 24 drives the lifting main shaft 18 to lift along the linear bearing 32, and the integrated beam 12 connected with the lifting main shaft 18 is lifted together with the stretched carbon fiber telescopic barrier group 21 to play a role in isolating passengers.

[0051] In one embodiment, the carbon fiber telescopic barrier group 21 is composed of nine carbon fiber telescopic barriers, each of which is composed of multiple sections of carbon fiber pipes that can be cumulatively overlapped and retracted.

[0052] The beneficial effects of the above technical solution are:

[0053] The carbon fiber telescopic barrier group 21 is set, and together with the stretched carbon fiber telescopic barrier group 21, it plays a role in isolating passengers.

[0054] In one embodiment, the floating plate 27 is located in the storage opening 14, and the carbon fiber telescopic barrier group 21 and the lifting main shaft 18 are both arranged through the floating plate 27. The floating plate 27 is used to fill the storage opening 14 after the integrated beam 12 is lifted.

[0055] The working principle and beneficial effects of the above technical solution are:

[0056] The floating plate 27 is arranged to fill the gap of the receiving opening 14 after the integrated beam 12 is lifted, so as to prevent foreign matters from falling into the fixed base 10.

[0057] In an embodiment, the civil foundation 13 is marked with a safety line, and the receiving opening 14 is located on the safety line, so as to return to the safety line after the integrated beam 12 is lowered.

[0058] The working principle and beneficial effects of the above technical solution are as follows:

[0059] After the integrated beam 12 is returned to the receiving opening 14, it is completely received below the ground, and the anti-skid strip 15 at the top end of the integrated beam 12 plays a role of replacing the safety line.

[0060] In an embodiment, the surface of the integrated beam 12 is embedded with a display screen 28 for broadcasting the vehicle model and shift, and the top end of the integrated beam 12 is further provided with a working indicator lamp 29 for working condition prompting and an emergency key switch 30.

[0061] The working principle and beneficial effects of the above technical solution are as follows:

[0062] The display screen 28 located on the side of the integrated beam 12 can display real-time related information according to the vehicle model and shift, and the working indicator lamp 29 with different colors can perform corresponding working condition prompting.

[0063] In an embodiment, the side end of the main shaft support base 19 is provided with a locking mechanism 31 for locking the lifting main shaft 18.

[0064] The working principle and beneficial effects of the above technical solution are as follows:

[0065] The locking mechanism locks the lifting main shaft 18 after it is lifted to the highest position, so as to avoid the situation of sliding down.

[0066] Obviously, the above embodiments are only examples for clearly illustrating, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
