A subway platform board lifting unit including a folding seat

Abstract

This invention discloses a subway platform lifting unit incorporating a folding seat. The unit includes a base with an open lower end and a flip-up cover at the upper end. A multi-point synchronous lifting unit is installed inside the base, allowing for vertical synchronous lifting and lowering of the base. During peak hours, the device is positioned below the platform surface, with the top cover flush with the platform floor. During off-peak hours, the base rises to a preset height above the platform, forming a seat. Staff can then flip up the two covers and secure them with U-shaped rods, creating a double-backed seat. This invention frees up station space during peak hours, ensuring efficient passage, and improves waiting comfort during off-peak hours. Utilizing a screw-type jack with all-metal mechanical transmission, it is more stable and safer than similar pneumatic jacks and eliminates the fire hazards associated with hydraulic lifts.

Description

Technical Field

[0001] This invention belongs to the field of urban rail transit station construction and decoration technology, specifically relating to a subway platform lifting unit that includes folding seats. Background Technology

[0002] Currently, traditional subway station platforms are fixed and lack lifting capabilities, with seats directly mounted on them. Both functions are singular and relatively independent. Subway station passenger flow exhibits tidal characteristics, with peak hours primarily occupied by commuters. These passengers prefer minimal ground obstructions and unobstructed walking space, and traditional fixed platform seats easily encroach on their waiting, standing, and passageway spaces. Furthermore, during equipment maintenance, emergency drills, or temporary events at the station, fixed seats can become obstacles, increasing the difficulty of on-site coordination and organization.

[0003] During off-peak hours, more elderly people go out for leisure and shopping, and with longer train intervals and waiting times, the demand for seating increases significantly. Platform seats often fall short of demand, with some passengers even squatting or sitting on the floor while waiting. While adding movable temporary seats could flexibly meet passenger needs, it requires additional storage space within the station, increasing station size and construction costs. Furthermore, the daily process of storing and moving temporary seats disrupts passenger waiting times and increases the workload of station staff.

[0004] Against this backdrop, liftable subway platform units with foldable seating integrate platform and seating functions, providing a good solution. Summary of the Invention

[0005] This invention is proposed to solve the problems existing in the prior art, and its purpose is to provide a subway platform lifting unit that includes folding seats.

[0006] The technical solution of the present invention is: a subway platform lifting unit including a folding seat, comprising a base, the lower end of which is open, a flip-up cover plate provided at the upper end of the base, and a multi-point synchronous lifting unit provided inside the base, the lifting unit performing vertical synchronous lifting of the base.

[0007] Furthermore, three cover plates are installed on the top surface of the base, with a fixed cover plate in the middle and flip-up cover plates on both sides.

[0008] Furthermore, the fixed cover is fixed to the top surface of the base, and the two flip-up covers are connected to the fixed cover via hinges. After the two flip-up covers are flipped open, they are connected as one to form a backrest structure.

[0009] Furthermore, the lifting unit is a screw lifting mechanism, and there are four screw lifting mechanisms arranged in a rectangular shape to form a stable surface support for the base based on four points.

[0010] Furthermore, the screw of the screw lifting mechanism is fixed to the lower surface of the base plate, the hollow tube seat of the screw lifting mechanism is connected to the pit, and the screw is retracted into the hollow tube seat.

[0011] Furthermore, a drive seat is provided below the base, and a motor is installed on top of the drive seat. The motor serves as a power source, connecting to the drive shaft of the cross-shaped steering mechanism to output forward and reverse rotation, thereby raising and lowering the base. A handwheel is also provided, connected to the drive shaft of the cross-shaped steering mechanism. In case of motor failure, the handwheel can be turned to raise or lower the base.

[0012] Furthermore, a transmission seat is provided below the base, and a T-shaped steering gear is installed on the top of the transmission seat. The T-shaped steering gear has one input end and two output ends, and the two output ends synchronously drive two screw lifting mechanisms.

[0013] Furthermore, the two shaft output ends of the T-shaped steering gear are connected to the screw lifting mechanism, and their ends form worm gears.

[0014] Furthermore, a lead screw nut is provided outside the screw, and the two form a lead screw pair. A worm wheel is formed outside the lead screw nut, and the worm wheel and worm form a worm wheel and worm pair.

[0015] Furthermore, the lower sides of the base form outward protrusions, thereby limiting the maximum lifting height of the base.

[0016] The beneficial effects of this invention are as follows: This invention discloses a subway platform lifting unit that includes folding seats. During peak passenger flow periods, the top surface of the device is flush with the platform surface, and the cover is laid flat so that passengers can stand or walk normally, maximizing the release of passage space. During off-peak passenger flow periods, the device rises to a preset height above the platform. Station staff can flip up the two flip-up cover plates on the top surface of the device and fix them with U-shaped rods to form double-back seats for waiting passengers.

[0017] This invention can free up station space and ensure traffic efficiency during peak hours, while improving waiting comfort during off-peak hours. It adopts a screw jack with all-metal mechanical transmission, which is more stable and safer than similar pneumatic jacks, and also eliminates the fire hazards caused by the oil used in hydraulic jacks.

[0018] Compared with existing technologies, this invention features multiple functions, flexible use, safety and reliability, and strong spatial adaptability. It is suitable for places with complex flow organization and high fire protection requirements, such as subway stations. It can also be extended to urban railway stations, high-speed rail stations, large passenger transport hubs, as well as places with high passenger flow organization requirements, such as large theaters and stadiums. It has high application prospects and promotion value. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1 to 6 As shown, a subway platform lifting unit including a folding seat includes a base 3, the lower end of which is open, and a flip-up cover 1 and a fixed cover 2 are provided on the upper end of the base 3. A multi-point synchronous lifting unit is provided inside the base 3, and the lifting unit performs vertical synchronous lifting of the base 3.

[0021] A fixed cover plate 2 is fixed to the top surface of the base with screws, and two flip-up cover plates 1 are connected to the fixed cover plate 2 by hinges 7. After the two flip-up cover plates 1 are flipped open, they are connected as one to form a backrest structure.

[0022] The lifting unit is a screw lifting mechanism 11. There are four screw lifting mechanisms 11 arranged in a rectangular shape, which form a stable surface support for the base 3 based on four points.

[0023] The screw 16 of the screw lifting mechanism 11 is fixed to the lower surface of the top plate of the base 3, and the hollow tube seat of the screw lifting mechanism 11 is connected to the pit.

[0024] A drive seat is provided below the base 3, and a motor 14 is installed on top of the drive seat. The motor 14 serves as a power source, connecting to the drive shaft 17 of the cross-shaped steering gear 13 to output forward and reverse rotation, thereby raising and lowering the base 3. A handwheel 15 is also provided and connected to the drive shaft 17 of the cross-shaped steering gear 13. In case of motor 14 failure, the handwheel 15 can be rotated to raise or lower the base 3.

[0025] A transmission seat is provided below the base 3, and a T-shaped steering gear 12 is installed on the top of the transmission seat. The T-shaped steering gear 12 has one input end and two output ends, and the two output ends synchronously drive two screw lifting mechanisms 11.

[0026] The two shaft output ends of the T-shaped steering gear 12 are connected to the screw lifting mechanism 11, and its ends form worm gears 21.

[0027] A lead screw nut is provided outside the lead screw 16, and the two form a lead screw pair. A worm wheel 22 is formed outside the lead screw nut. The worm wheel 22 and the worm 21 form a worm wheel and worm pair.

[0028] The lower parts of both sides of the base 3 form outward protrusions, which, together with the linkage screw-type lifting machine 5, can limit the maximum lifting height of the base 3.

[0029] Specifically, such as Figure 1 As shown, the fixed cover plate 2 is equipped with an audible and visual alarm 4, which is located between two flip-up cover plates 1. The two flip-up cover plates 1 form a backrest after being flipped.

[0030] Specifically, such as Figure 2 As shown, two of the sound and light alarms 4 are installed on the fixed cover plate 2. A U-shaped plug 8 and a flat lock 9 are installed on the side wall of the cover plate 1. The lifting unit is assembled into a linkage screw type lifting machine 5. The lifting component of the linkage screw type lifting machine 5 is four spiral screws 16. The control units of the sound and light alarms 4 and the linkage screw type lifting machine 5 are both connected to the control box 6.

[0031] Specifically, such as Figure 3 As shown, after the two flip-up cover plates 1 are flipped, the U-shaped insert rod 8 is removed to fix the two cover plates 1, and the two are locked by the flat lock 9. The base 3 provides two rows of seats on the left and right.

[0032] Specifically, an inspection valve 10 is provided on the base 3. The lifting unit at the bottom of the base 2 can be inspected and maintained through the inspection valve 10, and the base 3 can also be manually raised and lowered by turning the handwheel 15.

[0033] Specifically, the specific connections of the lifting unit are as follows: Figure 6 As shown, the motor 14 is connected to the cross steering gear 13 and drives the cross steering gear drive shaft 17 to rotate in both directions. At the same time, the cross steering gear drive shaft 17 extends outward, and a handwheel 15 is provided at the extended end, which can also drive the cross steering gear drive shaft 17 to rotate in both directions.

[0034] Specifically, the cross steering drive shaft 17 is provided with a first-stage drive tooth, which meshes with the cross steering driven teeth 18 on the two first-stage driven shafts, thereby driving the two first-stage driven shafts to rotate synchronously. At the same time, the first-stage driven shafts serve as the input of the T-type steering gear 12.

[0035] Specifically, the drive end of the first-stage driven shaft is provided with a T-type converter driven gear 19, and a T-type converter rotating gear 20 is provided on the normal output shaft of the T-type steering gear 12. The T-type converter driven gear 19 and the T-type converter rotating gear 20 mesh with each other to ensure that the four output shaft ends of the two T-type steering gears 12 are synchronized.

[0036] Specifically, the four output shafts of the T-shaped steering gear 12 are driven to rise and fall via a worm gear pair.

[0037] Meanwhile, bearings are installed at the corresponding positions of the shafts in the T-shaped steering gear 12, the cross steering gear 13, and the screw lifting mechanism 11, which will not be elaborated on here.

[0038] Specifically, the upper surface layer of the flip-up cover plate 1 and the fixed cover plate 2 is made of stone, and the lower surface layer is made of stainless steel.

[0039] Specifically, the base 3 is a stainless steel box.

[0040] Specifically, the base of the screw lifting mechanism 11 is installed in the pit under the platform.

[0041] Specifically, the screw lifting mechanism 11 employs two modes: electric lifting and manual lowering in case of motor failure. The motor 14 is connected to the control box 6 via the control power line 23.

[0042] Specifically, the audible and visual alarm 4 is linked with the screw lifting mechanism 11. When the screw lifting mechanism 11 is running, the audible and visual alarm 4 emits an audible and visual warning.

[0043] The control box 6 enables the motor 14 to rotate and the audible and visual alarm 4 to start and stop synchronously, and the screw lifting mechanism 11 to lift and lower stably and at a uniform speed. A double-sided flip-up cover 1 can be lifted and fixed to form a seat back using a U-shaped insert rod fixing device 8 and a lock hole 9. The entire system is reusable and has both automatic and manual control capabilities; all passenger contact parts are locked to ensure safety.

[0044] When installing on a subway station platform, holes and pits matching the base must be reserved in advance. The depth of the pit should be slightly greater than the height of the seat when it is fully folded up. The control box is installed on a nearby column or wall and is connected to the elevator and audible and visual alarms via control lines to achieve control.

[0045] During the morning peak hours, the lifting unit is retracted below the platform; during off-peak hours, the lifting unit can be raised to form a seat or the cover can be flipped up to form a backrest for passengers; during the evening peak hours, the lifting unit is retracted again.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
