[0002] With the acceleration of the urbanization process, people's attention to public safety has increased day by day. Especially in the face of emergencies such as possible wars, terrorist attacks or natural disasters, how to protect people's lives and property has become an important research topic. As an effective protective measure, air defense doors are widely used in many countries and regions. Early air defense facilities were mainly underground shelters, which became an important part of the comprehensive protection system.

[0003] An air defense door usually consists of a door frame, a door leaf, a locking device, a hinge system, etc. According to different protection requirements, it can be divided into various types, such as steel structure air defense doors, reinforced concrete structure air defense doors, etc. Its design takes into account sealing performance, durability and reliability to ensure that it can still be normally opened and closed under extreme conditions and provide necessary protection functions.

[0004] Due to the particularity of mountain rail transit, the line design mostly adopts a large longitudinal slope and a small line spacing. The track design mostly adopts small-spacing steel rails, and the train selection also adopts a rack railway train suitable for running on a large longitudinal slope. Currently, the conventional rail transit air defense doors used in mountain tunnels cannot meet its design characteristics, and the design and application of interval air defense doors suitable for such special rail transit lines in China are also in a blank state. Summary of the Invention

The gearbox includes an output shaft and a first input shaft, and the operating handwheel is connected to the first input shaft; one end of the transmission link is connected to the output shaft through the transmission assembly, and the other end is connected to the elevator body.

[0013] By adopting the above technical solution, the arrangement of the gearbox, the transmission assembly, and the transmission link enables the rotational motion of the operating handwheel to be smoothly transmitted to the elevator body, thereby driving the lifting push rod to perform lifting actions. The transmission path is simplified, the transmission efficiency is improved, and at the same time, the stability and reliability of the door leaf sliding in the vertical direction are ensured.

[0014] Optionally, the gearbox further includes a second input shaft, and a power source is provided on one side of the door leaf, and the power source is used to drive the second input shaft to rotate.

[0015] By adopting the above technical solution, the gearbox is provided with a second input shaft and cooperates with the power source on the door leaf, which can realize the automatic opening and closing of the door leaf, reduce the dependence on manual operation, and improve the opening and closing efficiency of the door leaf. At the same time, this design makes the operation of the air defense door more flexible, adapts to different working conditions, and is especially suitable for scenarios that require quick response.

[0016] Optionally, a first sealing block and a second sealing block are provided on the door leaf. The first sealing block is used for clamping connection with the rail groove, and the second sealing block is used for clamping connection with the tooth rail groove.

[0017] By adopting the above technical solution, the first sealing block on the door leaf is clamped with the rail groove, which can effectively prevent foreign objects from entering the rail groove and enhance the sealing performance between the door leaf and the rail groove; the second sealing block is clamped with the tooth rail groove, further improving the sealing effect between the door leaf and the tooth rail groove, ensuring that the air defense door has good sealing performance in the closed state, and meeting the requirements of the special environment of mountain rail transit.

Detailed implementation manners

[0024] The following further elaborates on the present application in conjunction with the attached Figures 1-8 drawings.

The door frame 1 includes a frame body 11 and a sill 12 fixed to the bottom of the frame body 11. The frame body 11 is specifically arranged in a rectangular frame shape with an open bottom. A rail groove 121 and a toothed rail groove 122 are formed on the sill 12. In this embodiment, two groups of rail grooves 121 are spaced apart on the sill 12, and each group of rail grooves 121 contains two rail grooves 121. Two toothed rail grooves 122 are provided, and one toothed rail groove 122 is located between the two rail grooves 121 in the same group. The designs of the rail groove 121 and the toothed rail groove 122 meet the driving requirements of small-spacing steel rails and toothed rail trains.

[0027] In other embodiments, a track can also be directly fixed on the sill 12 to form the rail groove 121 or the toothed rail groove 122; when directly installing the track, considering that trains mostly use track power supply, it is necessary to adjust the installation spacing of the track on the sill 12 to expand the insulation gap between the bottom and both sides of the track and the sill 12, which is beneficial to reducing the risk of abnormal sparking and grounding during the operation of the train.

[0028] Referring to Figure 1 , in this embodiment, two door leaves 2 are provided, and one is connected to each side of the frame body 11. Sliding hinge structures 5 are provided on both sides of the frame body 11, and the side edges of the door leaf 2 are rotatably connected to the frame body 11 through the sliding hinge structures 5.

The first hinge support 51 is fixedly connected to the side end of the frame body 11 by bolts, and the second hinge support 52 is also fixedly connected to the side end of the door leaf 2 by bolts. The first hinge support 51 includes a vertically arranged guide rod 511, and the second hinge support 52 includes a support body 522 and a guide sliding sleeve 521 hinged to the support body 522; the guide sliding sleeve 521 is sleeved outside the guide rod 511 and can slide vertically within a certain range on the guide rod 511. In this embodiment, two sliding hinge structures 5 are distributed at intervals along the vertical direction on one side of the frame body 11. The sliding hinge structure 5 can ensure the normal rotational connection of the door leaf 2 to the frame body 11 to realize the opening and closing of the door leaf 2. The sliding hinge structure 5 can also ensure that the door leaf 2 maintains a stable sliding trajectory during the lifting process, avoiding jamming caused by tilting or offset.

[0029] In other embodiments, the interior of the door leaf 2 is filled with keels, and an anti-explosion and anti-corrosion coating can also be applied to the outer surface of the door leaf 2. On the premise of maintaining the original strength and protection performance of the door leaf 2, the thickness of the door leaf 2 can be appropriately reduced, and the specifications of the keels inside the door leaf 2 can be compressed to achieve the purpose of reducing the self-weight of the door leaf 2. The anti-explosion and anti-corrosion coating can be selected as polyurea explosion-proof paint.

[0030] Referring to Figure 1 and Figure 2 , the locking device 3 includes a lock groove group and a number of lock bodies. The lock groove group includes a number of mating lock grooves, and the lock bodies are arranged in one-to-one correspondence with the mating lock grooves.

In this embodiment, the lock bodies are specifically provided with a first lock body 31 and a second lock body 32, and the mating lock grooves are specifically provided as a first lock groove 331 and a second lock groove 34. Two first lock bodies 31 are fixedly spaced at the top of the door leaf 2, and a first lock body 31 is also fixed on the side of the door leaf 2 close to the sliding hinge structure 5. Locking seats 33 corresponding to the first lock bodies 31 are fixed on the frame body 11, and the first lock grooves 331 are opened on the locking seats 33.

One end of the second lock body 32 tapers in the direction away from the door leaf 2 and is in a wedge shape.

[0031] When the door leaf 2 rotates to the closed state, the door leaf 2 slides vertically downward, and each lock body can be inserted into the corresponding mating lock groove, and the locking device 3 completes locking; when the door leaf 2 slides vertically upward, then each lock body can be disengaged from the corresponding mating lock groove, and the locking device 3 is unlocked. Each lock body and mating lock groove are located outside the door leaf 2 and the door frame 1, simplifying the structure of the locking device 3 and reducing the installation difficulty and maintenance difficulty of the locking device 3.

Two first sealing blocks 22 are provided corresponding to the rail grooves 121, and two second sealing blocks 23 are provided corresponding to the tooth rail grooves 122. In this embodiment, both the first sealing block 22 and the second sealing block 23 are made of rubber material and have good elasticity and sealing performance.

[0033] Referring to Figure 1, on the side edge of the frame body 11, a bearing support 14 and a guiding support 15 are fixedly arranged at intervals in the vertical direction. Both the bearing support 14 and the guiding support 15 are fixed to the frame body 11 by bolts. A vertically arranged guide post 151 is fixed on the guiding support 15. One side of the door leaf 2 is fixed with a linkage support 21 by bolts. One end of the linkage support 21 is provided with an opening and sleeved outside the guide post 151. A lifting structure 13 is further arranged on the side of the frame body 11. The lifting structure 13 includes a lift body 131 and a lifting push rod 132 slidably connected to the lift body 131. The lift body 131 is fixed on the bearing support 14. One end of the lifting push rod 132 abuts against the linkage support 21. One end of the guide post 151 penetrates into the lifting push rod 132. In this embodiment, the lift body 131 adopts a worm and worm gear type lift, which has excellent self-locking performance and can maintain a stable state without external force.

[0034] Referring to Figure 2 and Figure 4 , the driving device 4 includes an operating handwheel 41 and a transmission mechanism 42. The transmission mechanism 42 is fixed to the door leaf 2. The transmission mechanism 42 includes a gearbox 421, a transmission component 423 and a transmission connecting rod 422. The gearbox 421 is fixed to the door leaf 2 through a support. The gearbox 421 includes an output shaft 4213, a first input shaft 4211 and a second input shaft 4212. The operating handwheel 41 is coaxially fixed to the first input shaft 4211. The transmission connecting rod 422 is located inside the door leaf 2. One end of the transmission connecting rod 422 is connected to the output shaft 4213 through the transmission component 423, and the other end is connected to the transmission component inside the lift body 131. In this embodiment, the transmission component 423 is specifically set as a bevel gear set. In this embodiment, a multi-stage reduction gear is configured inside the gearbox 421 to increase the torque and reduce the speed, thereby improving the stability and safety of the system. When the operating handwheel 41 is rotated, the transmission mechanism 42 drives the lifting structure 13 to lift, so as to realize the lifting of the door leaf 2, and one door leaf 2 is equipped with a driving device 4.

[0035] In other embodiments, the transmission mechanism 42 can also be placed outside the door leaf 2 to reduce the installation difficulty and maintenance difficulty of the driving device 4.

[0036] Referring to Figure 4 , a power source 43 is further fixed on one side of the door leaf 2. The power source 43 is used to drive the second input shaft 4212 to rotate. The power source 43 is specifically selected as an electric motor. The output shaft 4213 of the electric motor is coaxially fixed to the second input shaft 4212. The power source 43 realizes an automatic driving function, which can further improve the operation efficiency. Especially in an emergency, it can quickly complete the lifting action of the door leaf 2.

[0037] Referring to Figure 2 and Figure 5, in order to improve the safety in use when the door leaf 2 is in the open state, a safety limit component 6 is further provided. The safety limit component 6 includes a limit seat 61, a limit pull rod 62 and an embedded locking member 64.

The limit vertical plate 612 is located on the side of the fixed base 611 close to the rail groove 121. An air damper 65 is fixed on the side of the limit vertical plate 612 away from the rail groove 121. When the door leaf 2 is in the open state, the air damper 65 abuts against the door leaf 2, and together with the limit vertical plate 612, it restricts the door leaf 2 from rotating towards the direction close to the rail groove 121 to ensure the normal open state of the door leaf 2. In this embodiment, the limit vertical plate 612 is detachably connected to the fixed base 611 by bolts.

[0038] Referring to Figure 2 and Figure 6 , the embedded locking member 64 includes an anchoring support 641 and a locking housing 642 that are fixedly connected to each other. The anchoring support 641 is anchored into the interior of the tunnel wall along the tunnel wall surface. A locking track 6421 for the end of the limit pull rod 62 to slide is provided on the locking housing 642. A clamping lock block 643 is fixed in the locking track 6421, and a clamping groove 6431 for the end of the limit pull rod 62 to be received is provided on the clamping lock block 643. A locking bolt 644 is inserted into the locking housing 642. One end of the limit pull rod 62 is fixedly connected to the door leaf 2. When the door leaf 2 is in the open state, the end of the limit pull rod 62 is located at the clamping groove 6431. The locking bolt 644 is inserted through the outer side wall of the locking housing 642 into the locking track 6421, and the locking bolt 644 abuts against the limit pull rod 62 to lock the limit pull rod 62, thereby ensuring the normal opening of the door leaf 2.

[0039] The implementation principle of this embodiment is as follows: The designs of the rail groove 121 and the tooth rail groove 122 meet the driving requirements of small-spacing rails and tooth rail trains. The designs of the sliding hinge structure 5 and the guiding support 15 ensure that the door leaf 2 maintains a stable sliding track during the lifting process; through the cooperation of the lifting structure 13 and the transmission mechanism 42, the precise opening and closing of the door leaf 2 are realized; through the settings of the first sealing block 22 and the second sealing block 23, the sealing performance between the door leaf 2 and the track is improved; through the synergistic effect of the limit seat 61 and the embedded locking member 64, the locking reliability of the door leaf 2 is enhanced. These designs work together to solve the problems of insufficient matching accuracy between the door body and the track and poor reliability of the locking device 3 in the prior art, and significantly improve the applicability and safety of the civil air defense door in the mountain rail transit environment.

[0040] Embodiment 2: Embodiment 2 of the present application provides a civil air defense door for mountain rail transit sections.

[0041] ReferenceFigure 7 and Figure 8 In Embodiment 2 of the present application, the difference from Embodiment 1 is that: in this embodiment, there is no locking pin 644, the end of the limit pull rod 62 away from the door leaf 2 is made of magnetic material, and the clamping lock block 643 is specifically set as an electromagnet; by controlling the energization or de-energization of the clamping lock block 643, the locking or unlocking function of the limit pull rod 62 can be realized. The end of the limit pull rod 62 is located at the clamping groove 6431. Energize the clamping lock block 643 to lock the limit pull rod 62, so as to ensure the normal opening of the door leaf 2.

[0042] Refer to Figure 7 and Figure 8 and, an opening degree control assembly 7 is provided on each door leaf 2. The opening degree control assembly 7 includes a distance measuring sensor 71 and a driving member. A stress sensor 63 is also provided on each limit pull rod 62. The distance measuring sensor 71 is electrically connected to a control module, and the driving member and the stress sensor 63 are both electrically connected to the control module.

[0043] In this embodiment, the driving member is specifically set as an electric cylinder 72. The electric cylinder 72 includes a cylinder body 721 and a piston rod 722 that are connected to each other. One end of the cylinder body 721 is hinged to the tunnel wall surface through a guiding support 15 to realize the rotational connection of the electric cylinder 72 on the tunnel wall surface, and the electric cylinder 72 can also slide vertically along the guide post 151 in the guiding support 15, so as to ensure the normal lifting of the door leaf 2. One end of the piston rod 722 is fixed with an elastic column 723, and one end of the elastic column 723 is hinged to the door leaf 2. The action of the electric cylinder 72 is controlled by the control module. By adjusting the telescopic length of the piston rod 722, the door leaf 2 is driven to rotate automatically, so as to control the opening degree of the door leaf 2. The elastic column 723 can be made of spring or rubber material, and can perform a certain degree of buffering to protect the connection between the door leaf 2 and the driving member.

[0044] Refer to Figure 7 and Figure 8 and, the stress sensor 63 is specifically selected as a strain gauge, which can monitor the stress condition of the limit pull rod 62 in real time. When abnormal stress is detected, the control module cuts off the power supply of the clamping lock block 643 to disconnect the connection between the limit pull rod 62 and the embedded locking member 64. In this embodiment, a buffer block 6432 is also fixed on the inner side wall of the clamping groove 6431, and the buffer block 6432 can be made of rubber material.

[0045] During the operation of the train in the tunnel, when the door leaf 2 is in the open state, positive and negative wind pressures will act on the door leaf 2 frequently, causing the door leaf 2 to vibrate. When the stress sensor 63 detects that the door leaf 2 is vibrating, the control module can timely control the clamping lock block 64 Power off, thus releasing the connection between the limit pull rod 62 and the embedded locking piece 64. At the same time, since the piston rod 722 and the door leaf 2 are flexibly connected through the elastic column 723, the door leaf 2 can vibrate freely within a certain range, thereby reducing the damage to the overall structure caused by the vibration of the door leaf 2 and improving the stability and reliability of the civil air defense door in a complex environment.

[0046] The implementation principle of the civil air defense door for the mountain rail transit section in Embodiment 2 of the present application is as follows: through the cooperation of the distance measuring sensor 71 and the driving member, precise control of the opening degree of the door leaf 2 is achieved; through the synergistic effect of the stress sensor 63 and the control module, the safety and reliability of the system are enhanced.
