Description

Technical Field

[0001] This invention belongs to the field of rail vehicle tunnel technology, and particularly relates to a folding canopy-type inner protective device and a tunnel containing the same. Background Technology

[0002] The connecting passageway of a rail vehicle is a crucial component for connecting and connecting two car bodies. It mainly consists of an outer folding canopy, treads, and an inner protective device. The inner protective device typically employs a protective plate structure or a folding canopy structure. For folding canopy-type inner protective devices, the overall stability of the folding canopy structure must be considered to address issues such as sag and vibration.

[0003] Patent CN208530566U discloses a vehicle passageway, in which the canopy assembly includes an inner canopy assembly and an outer canopy assembly. The canopy is supported by a coupler to provide anti-sagging support. Meanwhile, the inner canopy assembly is connected to the outer canopy assembly through metal plates set on each ring of the canopy frame, thereby improving the sagging problem of the inner canopy. However, although this canopy structure improves the sagging problem of the inner canopy, the anti-sagging of the inner canopy assembly depends on the connection and support of the outer canopy assembly, making it impossible to disassemble and replace the inner canopy assembly independently, which is inconvenient for maintenance.

[0004] Therefore, how to improve the sagging problem of the folding inner protective device without relying on the outer folding canopy is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention provides a folded inner protective device and a through channel containing it. The folded inner protective device provides vertical support through its own vertical support components, solving the sagging problem of the folded inner protective device. It does not rely on the connection support of the outer folded canopy and can be disassembled and replaced separately, making it convenient for maintenance.

[0006] This invention provides a folding inner protective device, comprising:

[0007] An inner folding tent includes a tent fabric and multiple folding tent frames for supporting the tent fabric, with the multiple folding tent frames arranged sequentially from the front end to the rear end of the inner folding tent.

[0008] Side beams are used to connect the inner canopy to the vehicle body. Side beams are provided on both sides of the front end and both sides of the rear end of the inner canopy.

[0009] A vertical support assembly for providing vertical support to the inner folding canopy, comprising:

[0010] Two rope steering seats are mounted opposite each other on the side beam at the front end and the side beam at the rear end.

[0011] Two tension springs are mounted opposite each other on the side beam at the front end and the side beam at the rear end;

[0012] Multiple support wheels are installed one by one on the side of the folding canopy frame;

[0013] The pull rope connects to and supports multiple support wheels in sequence. The two ends of the pull rope pass over two pull rope steering seats and are connected to two tension springs to tension the pull rope.

[0014] This technical solution provides vertical support through the vertical support components built into the inner folding canopy itself, without relying on the connection support of the outer folding canopy. It can solve the problem of sagging and wrinkling of the inner folding canopy while meeting the product's functional requirements, thereby improving the overall stability and aesthetics of the folding canopy-type inner protective device. It can also be disassembled and replaced separately for easy maintenance.

[0015] In some embodiments, one end of the tension spring connecting to the pull rope is provided with a movable seat, and the movable seat has a locking part; the pull rope deflector seat has a slot for the locking part to engage and lock the movable seat. This technical solution, through the cooperation between the locking part of the movable seat and the slot of the pull rope deflector seat, makes the connection and hanging operation of the folding inner protective device more convenient and helps to improve the connection and hanging efficiency.

[0016] In some embodiments, the cable steering seat is located on the side of the side beam away from the vehicle body. The side beam has a through-hole communicating with the latch. A push-spring piece with its end extending into the through-hole is located on the side of the side beam facing the vehicle body. When the side beam is connected to the vehicle body, the push-spring piece is pressed against the latching part inside the latch by the pressure of the vehicle body, causing the latching part to disengage from the latch. This technical solution uses the push-spring piece to automatically disengage the latching part of the movable seat from the latch of the cable steering seat, thereby quickly achieving cable tensioning.

[0017] In some embodiments, there are four sets of vertical support components, with two sets of vertical support components provided on each side of the inner folded canopy. Of the two sets of vertical support components located on the same side of the inner folded canopy, one set is located near the upper part of the inner folded canopy, and the other set is located near the lower part of the inner folded canopy. This technical solution, by providing vertical support components at both the upper and lower parts of both sides of the inner folded canopy, can ensure that both sides of the inner folded canopy receive vertical support, thereby improving the vertical support effect and ensuring that the inner folded canopy will not sag or wrinkle.

[0018] In some embodiments, in the vertical support assembly located near the upper part of the inner folding canopy, a tension spring is positioned below the tension rope to stretch and tighten it downwards; in the vertical support assembly located near the lower part of the inner folding canopy, a tension spring is positioned above the tension rope to stretch and tighten it upwards. This technical solution, by stretching and tightening the tension rope at the upper part of the inner folding canopy downwards while stretching and tightening the tension rope at the lower part upwards, can support the entire inner folding canopy towards the center, ensuring that the inner folding canopy does not sag or wrinkle.

[0019] In some embodiments, the top front and rear ends of the inner folding canopy are respectively provided with crossbeams for connecting to the vehicle body; the folding canopy inner protective device also includes upper mounting seats installed on both sides of the upper part of the vehicle body, and lower mounting seats installed on both sides of the lower part of the vehicle body; the upper mounting seats have slots, and the two ends of the crossbeams are respectively engaged with the upper mounting seats on both sides of the upper part of the vehicle body; the lower mounting seats are provided with positioning pins, and the lower part of the side beams is provided with connecting blocks that are sleeved on the positioning pins. This technical solution realizes the rapid connection and disassembly of the folding canopy inner protective device through the sleeved engagement of the connecting blocks provided on the lower part of the side beams with the positioning pins of the lower mounting seats, and the snap-fit ​​engagement of the crossbeams at the top of the inner folding canopy with the upper mounting seats, which can effectively improve the efficiency of connection and disassembly operations and facilitate subsequent inspection and maintenance.

[0020] In some embodiments, the ends of the crossbeam are hollow, and an upper connecting assembly for detachably connecting to the upper mounting base is provided inside the ends of the crossbeam. The upper connecting assembly includes:

[0021] The pin can extend or retract relative to the end of the crossbeam, and the groove wall opposite to the end of the crossbeam has a pin hole for the pin to be inserted.

[0022] A spring is used to press the pin against the pin hole, and it abuts against the end of the pin away from the pin hole;

[0023] The stop shaft is used to drive the extension and retraction of the pin. It is connected to the end of the pin away from the pin hole by a connecting rope. The crossbeam has a slide groove arranged along the extension and retraction direction of the pin. The stop shaft moves in the slide groove to drive the extension and retraction of the pin.

[0024] This technical solution, through the design of the upper connecting component, facilitates the uncoiling operation while ensuring a stable connection between the crossbeam and the upper mounting base. This effectively prevents accidental disassembly of the folding inner protective device due to bumps or other reasons during train operation, thus improving safety.

[0025] In some embodiments, the end of the slide away from the end of the crossbeam is provided with a locking groove into which the stop shaft can be engaged to restrict its movement. When the stop shaft is engaged in the locking groove, the pin is located at the retracted end of the crossbeam. This technical solution restricts the movement of the stop shaft by setting a locking groove, which can fix the pin at the retracted end of the crossbeam, making it easy to push the crossbeam out of the upper mounting base without the need for multiple people to operate, and facilitating the disassembly and assembly of the folding inner protective device.

[0026] In some embodiments, the side of the upper mounting base away from the slot forms a slope from top to bottom towards the slot, and the end of the pin has an inclined surface in the same direction as the slope. As the end of the crossbeam falls into the slot from top to bottom, the pin slides on the slope of the upper mounting base via the inclined surface, causing the pin to retract into the end of the crossbeam and compress the spring. After the end of the crossbeam enters the slot, the spring extends and pushes the pin into the pin hole. This technical solution, through the slope at the slot and the inclined surface at the end of the pin, can automatically retract the pin as the crossbeam falls into the slot from top to bottom, making the coupling operation easier.

[0027] In addition, the present invention also provides a through passage, including the above-mentioned folded inner protective device.

[0028] Based on the above technical solution, the folding inner protective device in this embodiment of the invention provides vertical support force through its own vertical support components, which solves the sagging problem of the folding inner protective device. It does not rely on the connection support of the outer folding canopy and can be disassembled and replaced separately, making it convenient for maintenance. Attached Figure Description

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

Figure 2 The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0050] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0051] As attached Figures 1-6 As shown, in an illustrative embodiment of the folding inner liner device of the present invention, the folding inner liner device includes an inner folding canopy 1, side beams 2, and a vertical support assembly 3; the inner folding canopy 1 includes a canopy 101 and a plurality of folding canopy frames 102 for supporting the canopy 101, the plurality of folding canopy frames 102 being arranged sequentially from the front end to the rear end of the inner folding canopy 1; the side beams 2 are used to connect the inner folding canopy 1 to the vehicle body, and side beams 2 are respectively provided on both sides of the front end and both sides of the rear end of the inner folding canopy 1; the vertical support assembly 3 is used to provide vertical support force to the inner folding canopy 1, and includes two pull rope steering seats 304 and two tension springs 3 01. Multiple support wheels 302 and pull ropes 303; two pull rope steering seats 304 are disposed opposite to each other on the side beam 2 at the front end and the side beam 2 at the rear end; two tension springs 301 are disposed opposite to each other on the side beam 2 at the front end and the side beam 2 at the rear end; the support wheels 302 are installed one-to-one on the side of the folding frame 102; the pull ropes 303 are connected to multiple support wheels 302 in sequence and support the support wheels 302; the two ends of the pull ropes 303 pass around the two pull rope steering seats 304 respectively and are connected to the two tension springs 301 so as to tension the pull ropes 303 through the two tension springs 301.

[0052] In the above-mentioned folding canopy type inner protective device, it should be noted that the side of the folding canopy frame 102 is provided with a support wheel seat 307, and the pull rope 303 is threaded through the support wheel seat 307 to prevent the pull rope 303 from separating from the support wheel 302 and to ensure the vertical support effect.

[0053] The aforementioned folding inner protective device provides vertical support to each frame 102 of the inner folding 1 by tensioning the tension rope 303 with tension springs 301 symmetrically arranged at the front and rear ends of the inner folding 1. The tension rope 303 supports the support wheels 302 on each folding frame 102. This solves the problem of sagging and wrinkling of the inner folding 1 while meeting product functionality, improving the overall stability and aesthetics of the folding inner protective device. Furthermore, the folding inner protective device provides vertical support through its own vertical support components 3, independent of the external folding support, and can be disassembled and replaced independently for easy maintenance.

[0054] In some embodiments, such as Figure 5 and Figure 6As shown, one end of the tension spring 301 connected to the pull rope 303 is provided with a movable seat 306, and the movable seat 306 is provided with a locking part 3061; the pull rope deflector seat 304 is provided with a locking slot a for the locking part 3061 to be engaged to lock the movable seat 306. When attaching the folding canopy inner protective device, first connect one end of the inner folding canopy 1 to a car body via the side beam 2. By pulling the movable seat 306 connected to the tension spring 301 on the other end of the side beam 2 of the inner folding canopy 1, the locking part 3061 of the movable seat 306 is engaged into the slot a of the pull rope steering seat 304, thereby locking the movable seat 306 and putting the tension spring 301 in the maximum tension state, thereby relaxing the pull rope 303 and allowing the inner folding canopy 1 to extend to the maximum extent so that the other end of the inner folding canopy 1 can be connected to another car body, completing the attachment of the folding canopy inner protective device. After attachment, disengage the locking part 3061 of the movable seat 306 from the slot a of the pull rope steering seat 304, and the tension spring 301 will tighten the pull rope 303, providing vertical support. In this embodiment, the engagement of the locking part 3061 of the movable seat 306 and the locking slot a of the pull rope steering seat 304 makes the connection operation of the folding inner protective device more convenient and helps to improve the connection efficiency.

[0055] In some embodiments, to facilitate the disengagement of the locking portion 3061 of the movable seat 306 from the locking slot a of the pull rope steering seat 304 after the folding inner protective device is attached, such as... Figure 6 As shown, the pull rope steering seat 304 is located on the side of the side beam 2 away from the vehicle body. The side beam 2 has a through opening b that is connected to the bayonet a. The side of the side beam 2 facing the vehicle body has a push spring 308 with its end extending into the through opening b. When the side beam 2 is connected to the vehicle body, the push spring 308 is pushed by the squeezing action of the vehicle body to push the locking part 3061 locked in the bayonet a, so that the locking part 3061 is disengaged from the bayonet a. When the folding inner protective device is engaged, the side beam 2 at the end of the inner folding canopy 1 is in contact with the vehicle body, so the vehicle body will squeeze the push spring 308. The push spring 308 moves from the through-hole b of the side beam 2 towards the latch a of the pull rope steering seat 304, thereby pushing the locking part 3061 of the movable seat 306 out of the latch a of the pull rope steering seat 304. Thus, while the folding inner protective device is engaged, the locking part 3061 of the movable seat 306 is disengaged from the latch a of the pull rope steering seat 304, thereby quickly achieving the tensioning of the pull rope 303. It should be noted that in this embodiment, the through-hole b and the latch a are connected in the horizontal direction. The push spring 308 is bent in an L-shape. The top end of the push spring 308 is fixedly connected to the side beam 2, and the bottom end extends into the through-hole b in the horizontal direction. The bent part of the push spring 308 protrudes towards the side away from the side beam 2 so that when it is squeezed by the vehicle body, the bottom end of the push spring 308 can extend from the through-hole b into the latch a of the pull rope steering seat 304.

[0056] In some embodiments, such as Figure 3As shown, there are four sets of vertical support components 3, with two sets of vertical support components 3 provided on each side of the inner folded canopy 1. Of the two sets of vertical support components 3 located on the same side of the inner folded canopy 1, one set of vertical support components 3 is located near the upper part of the inner folded canopy 1, and the other set of vertical support components 3 is located near the lower part of the inner folded canopy 1. By providing vertical support components 3 at both the upper and lower parts of both sides of the inner folded canopy 1, both sides of the inner folded canopy 1 can be vertically supported. At the same time, the upper and lower parts of each side of the inner folded canopy 1 can also be vertically supported, improving the vertical support effect and ensuring that the inner folded canopy 1 will not sag or wrinkle.

[0057] In some embodiments, such as Figure 3 As shown, in the vertical support assembly 3 located near the upper part of the inner folding canopy 1, the tension spring 301 is positioned below the pull rope 303 to tension the pull rope 303 downwards; in the vertical support assembly 3 located near the lower part of the inner folding canopy 1, the tension spring 301 is positioned above the pull rope 303 to tension the pull rope 303 upwards. By tensioning the pull rope 303 at the upper part of the inner folding canopy 1 downwards and the pull rope 303 at the lower part upwards, the entire inner folding canopy 1 can be stretched towards the center to ensure that the inner folding canopy 1 will not sag or wrinkle. It should be noted that in this embodiment, the tension spring 301 is preferably arranged vertically, and two tension springs 301 are connected to the same tension spring connecting seat 305, thereby facilitating the installation of the vertical support assembly 3.

[0058] In some embodiments, such as Figure 1 , Figure 3 , Figure 4 , Figures 7-9 As shown, the front and rear tops of the inner folding canopy 1 are respectively provided with crossbeams 4 for connecting to the vehicle body; the folding canopy inner protective device also includes upper mounting seats 6 installed on both sides of the upper part of the vehicle body, and lower mounting seats 5 installed on both sides of the lower part of the vehicle body; the upper mounting seats 6 have slots, and the two ends of the crossbeams 4 are respectively inserted into the upper mounting seats 6 on both sides of the upper part of the vehicle body; the lower mounting seats 5 are provided with positioning pins 501, and the lower part of the side beams 2 is provided with connecting blocks 7 that are sleeved on the positioning pins 501. When connecting one end of the inner folding canopy 1 to the corresponding vehicle body, first put the connecting blocks 7 at the lower part of the side beams 2 onto the positioning pins 501 of the corresponding lower mounting seats 5, then straighten the inner folding canopy 1, push the crossbeams 4 upward, so that the two ends of the crossbeams 4 are respectively inserted into the slots of the two upper mounting seats 6, so that the end of the inner folding canopy 1 is attached to the vehicle body; when unhooking, the operation is reversed to complete the removal of the inner folding canopy 1 from the vehicle body. In this embodiment, the quick connection and disassembly of the folding inner protective device are achieved through the sleeve engagement between the connecting block 7 at the lower part of the side beam 2 and the positioning pin 501 of the lower mounting base 5, and the snap engagement between the crossbeam 4 at the top of the inner folding canopy 1 and the upper mounting base 6. This can effectively improve the efficiency of connection and disassembly operations and facilitate subsequent inspection and maintenance.

[0059] In some embodiments, such as Figure 9 and Figure 10As shown, the end of the crossbeam 4 is hollow, and the end of the crossbeam 4 is provided with an upper connecting assembly 8 for detachable connection to the upper mounting base 6. The upper connecting assembly 8 includes a pin 801, a spring 802, and a retaining shaft 804. The pin 801 can extend or retract relative to the end of the crossbeam 4. The groove wall opposite to the end of the crossbeam 4 has a pin hole c for the pin 801 to be inserted. The spring 802 is used to press the pin 801 against the pin hole c, and it abuts against the end of the pin 801 away from the pin hole c. The retaining shaft 804 is used to drive the pin 801 to extend and retract, and it is connected to the end of the pin 801 away from the pin hole c by a connecting rope 803. The crossbeam 4 has a sliding groove 401 arranged along the extension and retraction direction of the pin 801, and the retaining shaft 804 moves in the sliding groove 401 to drive the pin 801 to extend and retract. In this embodiment, the pin 801 is pressed against the pin hole c of the upper mounting seat 6 under the force of the spring 802, which can realize the stable connection between the crossbeam 4 and the upper mounting seat 6. This can effectively prevent the folding inner protective device from being accidentally disassembled due to bumps or other reasons during train operation, thus improving safety. At the same time, by pulling the stop shaft 804, the connecting rope 803 can be used to pull the pin 801 back, thereby pushing the crossbeam 4 out of the upper mounting seat 6, which can release the connection between the crossbeam 4 and the upper mounting seat 6, facilitating the disassembly and reassembly of the folding inner protective device.

[0060] In some embodiments, such as Figure 9 As shown, the end of the slide groove 401 away from the end of the crossbeam 4 is provided with a locking groove 4011 into which the stop shaft 804 can be engaged to restrict the movement of the stop shaft 804. When the stop shaft 804 is engaged in the locking groove 4011, the pin 801 is located at the end of the retracted crossbeam 4. By restricting the movement of the stop shaft 804 by the locking groove 4011, the pin 801 can be fixed at the end of the retracted crossbeam 4, which makes it easy to push the crossbeam 4 out of the upper mounting base 6 without the need for multiple people to operate, and facilitates the disassembly and assembly of the folding inner protective device.

[0061] In some embodiments, such as Figure 10 As shown, the upper mounting base 6 has a slope d from top to bottom towards the slot on the side away from the slot. The end of the pin 801 has an inclined surface e in the same direction as the slope d. As the end of the crossbeam 4 falls into the slot from top to bottom, the pin 801 slides on the slope d of the upper mounting base 6 via the inclined surface e, so that the pin 801 retracts into the end of the crossbeam 4 and compresses the spring 802. After the end of the crossbeam 4 falls into the slot, the spring 802 extends and pushes the pin 801 into the pin hole c. The slope d at the slot, in conjunction with the inclined surface e at the end of the pin 801, allows the pin 801 to retract automatically as the crossbeam 4 falls into the slot from top to bottom, making the coupling operation easier.

[0062] Based on the above-described folded inner protective device, the present invention also provides a through passage, which includes the above-described folded inner protective device.

[0063] The following is in conjunction with the appendix Figures 1-10 The following describes the specific connection and disconnection process of one embodiment of the folding inner protective device and the through-channel containing it of the present invention:

[0064] (1) Connecting process

[0065] The process of connecting one end of the inner folding canopy 1 to the corresponding vehicle body is as follows: First, the connecting block 7 at the lower part of the side beam 2 is fitted onto the positioning pin 501 of the corresponding lower mounting seat 5. Then, the inner folding canopy 1 is straightened, the crossbeam 4 is pushed upward, and the crossbeam 4 is loosened so that both ends of the crossbeam 4 are respectively inserted into the slots of the two upper mounting seats 6. During the process of the end of the crossbeam 4 falling into the slot of the upper mounting seat 6 from top to bottom, the pin 801 slides on the slope d of the upper mounting seat 6 through the inclined surface e, so that the pin 801 retracts into the end of the crossbeam 4 and compresses the spring 802. After the end of the crossbeam 4 falls into the slot, the spring 802 extends and pushes the pin 801 into the pin hole c of the upper mounting seat 6, thus completing the connection between one end of the inner folding canopy 1 and the vehicle body.

[0066] The other end of the inner folding canopy 1 is connected to the corresponding vehicle body. The specific process is as follows: by pulling the movable seat 306 connected to the tension spring 301 on the side beam 2 at the other end of the inner folding canopy 1, the locking part 3061 of the movable seat 306 is locked into the slot a of the pull rope steering seat 304 to lock the movable seat 306, so that the tension spring 301 is in the maximum tension state, thereby relaxing the pull rope 303 and allowing the inner folding canopy 1 to extend to the maximum extent; then the connecting block 7 at the lower part of the side beam 2 is put onto the positioning pin 501 of the corresponding lower mounting seat 5, the inner folding canopy 1 is straightened, and the crossbeam 4 is pushed upward so that the two ends of the crossbeam 4 are respectively locked into the slots of the two upper mounting seats 6, thus completing the connection between the other end of the inner folding canopy 1 and the vehicle body.

[0067] The tensioning of the vertical support assembly 3 is as follows: After the inner folding canopy 1 is connected to the vehicle body, the side beam 2 at the end of the inner folding canopy 1 is in contact with the vehicle body, and the vehicle body squeezes the push spring 308, causing the push spring 308 to move from the through-hole b of the side beam 2 towards the slot a of the rope steering seat 304, thereby pushing the locking part 3061 of the movable seat 306 out of the slot a of the rope steering seat 304, so as to tension the rope 303 through the tension spring 301 and play a vertical support role.

[0068] (2) Decompilation process

[0069] By pulling the stop shaft 804 of the connecting assembly 8 at the end of the crossbeam 4, the connecting rope 803 pulls the pin 801 back, and the stop shaft 804 is engaged in the locking groove 4011, so that the pin 801 is locked in the position at the retracted end of the crossbeam 4. Then, the crossbeam 4 is pushed out from the upper mounting seat 6, and the connection between the crossbeam 4 and the upper mounting seat 6 is released. Then, the inner folding shed 1 is pulled upward, so that the connecting block 7 at the lower part of the side beam 2 is disengaged from the positioning pin 501 of the lower mounting seat 5, and the uncoiling is completed.

[0070] Through the description of several embodiments of the folded inner protective device and the through channel comprising thereof of the present invention, it can be seen that the embodiments of the folded inner protective device and the through channel comprising thereof of the present invention have at least one or more of the following advantages:

[0071] 1.
