Abstract

This invention discloses a support assembly suitable for evacuation platforms, including a sleeve and a support rod. The sleeve is used to connect to the evacuation platform; alternatively, the sleeve is formed on the evacuation platform. The support rod is configured such that one end is connected to the tunnel wall, and the other end is reciprocally moved within the sleeve along its axial direction. This configuration facilitates adjusting the angle of the evacuation platform by adjusting the total length of the support rod and the sleeve, ensuring the evacuation platform is level. In practical applications, since one side of the evacuation platform is hinged to the tunnel wall, and the other side has a sleeve formed or connected to it, a suitable installation position can be selected based on the location of specialized equipment such as high-voltage cable supports below the evacuation platform. One end of the support rod is installed on the tunnel wall, and the other end is installed within the sleeve. Then, the position of the support rod relative to the sleeve is adjusted to level the evacuation platform, achieving the effect of ensuring the evacuation platform is level and avoiding interference with specialized equipment.

[0002] Subways are densely populated public places, making safety paramount. In the event of an emergency during subway operation, the priority must be ensuring the safe and rapid evacuation of passengers. Therefore, subway designs and construction must include appropriate safety passages, with evacuation platforms being one type of such passage.

[0003] In the civil engineering of evacuation platforms, the supporting structure of the evacuation platform generally adopts a triangular stable structure. In existing technology, fixed-length steel diagonal braces are usually used, which are connected to the lining plates on the lining segments by welding or pinning at a fixed angle. However, due to the difficulty in controlling the installation angle of the support on site, the accuracy of the installation is limited, making it difficult to ensure the level of the evacuation platform; at the same time, there is also the problem of the supporting structure conflicting with the high-voltage cable support directly below it. Summary of the Invention

[0004] In view of the above problems, the present invention provides a support component suitable for evacuation platforms that overcomes or at least partially solves the above problems, and can achieve the effect of ensuring the level of the evacuation platform and avoiding interference with the system's specialized equipment.

[0005] Specifically, the present invention provides a support component suitable for evacuation platforms, comprising:

[0006] A sleeve for connecting to the evacuation platform; or, the sleeve is formed on the evacuation platform;

[0007] A support rod, wherein one end of the support rod is configured to connect to the inner wall of the tunnel, and the other end is installed inside the casing for reciprocating movement along the axial direction of the casing.

[0008] According to one embodiment of the present invention, the inner wall of the sleeve is provided with a first thread, and the other end of the support rod is provided with a second thread that engages with the first thread.

[0009] According to one embodiment of the present invention, the support component further includes:

[0010] A limiting device, which is fixedly mounted on the support rod;

[0011] A sleeve clip is connected to the sleeve and is reciprocally moved along the axial direction of the sleeve; the sleeve clip is configured to engage with the limiting device when in a locked state and disengage from the limiting device when in an unlocked state.

[0012] According to one embodiment of the present invention, the support component further includes:

[0013] A positioning component is detachably connected to the inner wall of the tunnel, and a support rod is rotatably connected to the positioning component.

[0014] According to one embodiment of the present invention, a plurality of first tooth-shaped grooves are formed on the outer wall of the sleeve, and the plurality of first teeth are evenly distributed along the circumference of the sleeve;

[0015] The limiting device has a plurality of second tooth-shaped grooves, and the plurality of second tooth-shaped grooves are arranged in a one-to-one correspondence with the first tooth-shaped grooves;

[0016] The inner wall of the sleeve buckle has tooth-shaped protrusions that match the first tooth-shaped groove and the second tooth-shaped groove.

[0017] According to one embodiment of the present invention, the diameter of the limiting device is the same as the outer diameter of the sleeve.

[0018] According to one embodiment of the present invention, the top of the sleeve is provided with a first pin hole for detachable connection with the evacuation platform by means of a pin.

[0019] According to one embodiment of the present invention, the positioning component includes a sleeve, the inner wall of which is formed with a plurality of annular grooves, and the support rod is formed with an annular protrusion located within the annular grooves; the annular grooves and the annular protrusions are loosely fitted.

[0020] According to one embodiment of the present invention, a second pin hole is formed on the sleeve for detachable connection with the inner wall of the tunnel by means of a pin.

[0021] According to one embodiment of the present invention, a rotating strut is connected to the support rod, and the axial direction of the rotating strut is perpendicular to the axial direction of the support rod.

[0022] The beneficial effects of this invention are as follows:

[0023] In the support assembly for evacuation platforms provided by this invention, the support rod is installed inside the sleeve by reciprocating movement along the axial direction of the sleeve. This allows for adjustment of the total length of the support rod and the sleeve, thereby adjusting the angle of the evacuation platform and ensuring its horizontality. In practical applications, since one side of the evacuation platform is hinged to the tunnel wall and the other side has a sleeve formed or connected to it, a suitable installation position can be selected based on the location of specialized equipment such as high-voltage cable supports below the evacuation platform. One end of the support rod is installed on the tunnel wall, and the other end is installed inside the sleeve. Then, the position of the support rod relative to the sleeve is adjusted, thereby adjusting the angle of the evacuation platform to ensure its horizontality and avoid interference with specialized equipment.

[0024] Furthermore, the support assembly also includes a limiting device and a sleeve clip. The limiting device is fixedly mounted on the support rod; the sleeve clip is connected to the sleeve; the sleeve clip is configured to engage with the limiting device when locked and disengage from the limiting device when unlocked. This configuration allows the sleeve clip to engage with the limiting device after the evacuation platform is rotated to a horizontal position, securing the sleeve and support rod and preventing relative rotation between them, thereby improving the safety of the evacuation platform.

[0033] The following reference Figures 1 to 5This invention describes a support component suitable for an evacuation platform according to embodiments of the present invention.

When a feature "includes or contains" one or more of the features it encompasses, unless otherwise specifically described, this indicates that other features are not excluded and may be further included.

[0034] Unless otherwise expressly specified and limited, the terms "set up," "install," "connect," "link," "fix," and "couple" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art should be able to understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] Furthermore, in the description of this embodiment, "above" or "below" the second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. That is, in the description of this embodiment, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0037] In the civil engineering of evacuation platforms, the support structure typically adopts a triangular, stable structure. During installation, fixed-length steel diagonal braces are adjusted to their position and angle, and then connected to the lining plates on the lining segments via welding or pins after being tilted and fixed at the desired angle. However, controlling the installation angle of the supports on-site is difficult, making it hard to ensure the evacuation platform is level. Furthermore, when installing one end of the steel diagonal brace, the other end is prone to relative displacement, resulting in limited installation accuracy. Additionally, there is a possibility of conflict between the support structure and the high-voltage cable support directly below it.

[0038] Based on this, the inventors have creatively proposed a support component suitable for evacuation platforms that can ensure the level of the evacuation platform while avoiding interference with specialized system equipment. Among these components... Figure 1 This is a schematic structural diagram of a support component according to an embodiment of the present invention, such as... Figure 1 As shown, and refer to Figures 2 to 5 This invention provides a support assembly suitable for an evacuation platform, including a sleeve 100 and a support rod 200. The sleeve 100 is used to connect to the evacuation platform 300; or, the sleeve 100 is formed on the evacuation platform 300. The support rod 200 is configured such that one end is used to connect to the inner wall of the tunnel, and the other end is reciprocated along the axial direction of the sleeve 100 and installed inside the sleeve 100.

[0039] In this embodiment of the invention, the support rod 200 is installed inside the sleeve 100 by reciprocating movement along the axial direction of the sleeve 100, so as to adjust the total length of the support rod 200 and the sleeve 100, thereby adjusting the angle of the evacuation platform 300 and ensuring that the evacuation platform 300 is horizontal. In practical applications, since one side of the evacuation platform 300 is hinged to the inner wall of the tunnel and the other side is formed or connected to the sleeve 100, a suitable installation position can be selected according to the position of the professional equipment such as the high-voltage cable support below the evacuation platform 300. One end of the support rod 200 is installed on the inner wall of the tunnel, and the other end of the support rod 200 is installed inside the sleeve 100. Then, the position of the support rod 200 relative to the sleeve 100 is adjusted, thereby adjusting the angle of the evacuation platform 300 to make the evacuation platform 300 horizontal, achieving the effect of ensuring that the evacuation platform 300 is horizontal and avoiding interference with the professional equipment of the system.

[0040] Specifically, such as Figure 2As shown, the inner wall of the sleeve 100 is provided with a first thread, and the other end of the support rod 200 is provided with a second thread that meshes with the first thread. One end of the support rod 200 is rotatably connected to the inner wall of the tunnel. In application, when the support rod 200 is rotated, because the sleeve 100 is formed or connected to the evacuation platform 300 and is constrained by the evacuation platform 300, the sleeve 100 meshing with the support rod 200 cannot rotate when the support rod 200 rotates. Therefore, the support rod 200 and the sleeve 100 can only move in the axial direction of the support rod 200, lengthening or shortening the length of the end of the support rod 200 without the second thread and the sleeve 100. Since the support rod 200 is connected to the inner wall of the tunnel, the sleeve 100 drives the evacuation platform 300 to rotate, rotating the evacuation platform 300 to a horizontal position.

[0041] Because the sleeve 100 and the support rod 200 are engaged by the first thread and the second thread, after the evacuation platform 300 is rotated to a horizontal position, with prolonged use, the sleeve 100 and the support rod 200 are prone to relative rotation, causing the evacuation platform 300 to become non-horizontal. Simultaneously, due to the engagement of the sleeve 100 and the support rod 200, the connection is not stable and difficult to withstand force. Therefore, the inventors have creatively proposed several embodiments in which the support assembly further includes a limiting device 400 and a sleeve latch 500. The limiting device 400 is fixedly mounted on the support rod 200; the sleeve latch 500 is connected to the sleeve 100 and is reciprocally movable along the axial direction of the sleeve 100; the sleeve latch 500 is configured to engage with the limiting device 400 when in a locked state and disengage from the limiting device 400 when in an unlocked state. With this configuration, after the evacuation platform 300 is rotated to a horizontal position, the sleeve buckle 500 can engage with the limiting device 400 to fix the sleeve 100 and the support rod 200, preventing the sleeve 100 and the support rod 200 from rotating relative to each other, thereby improving the safety of the evacuation platform 300.

[0042] In some embodiments of the present invention, such as Figure 1 , Figure 3As shown, the support assembly also includes a positioning component 600, which is detachably connected to the tunnel inner wall. The support rod 200 is rotatably connected to the positioning component 600. It should be noted that the rotatable connection between the support rod 200 and the positioning component 600 includes the following: the support rod 200 can rotate about the positioning component 600 as a center, and the support rod 200 can rotate circumferentially. First, since the support rod 200 engages with the sleeve 100, when the support rod 200 rotates, it also rotates relative to the positioning component 600. Second, because the angle between the evacuation platform 300 and the tunnel inner wall changes after extending or shortening the length of the end of the support rod 200 without the second thread and the sleeve 100, the angle between the support rod 200 and the tunnel inner wall also changes. This arrangement allows the positioning component 600 to not only provide a force-bearing point for the support rod 200 but also facilitates the rotation of the support rod 200. During installation, the positioning component 600 can be directly installed on the inner wall of the tunnel. Then, the support rod 200 is inserted into the sleeve 100, and the evacuation platform 300 is adjusted by rotating the support rod 200. It is not necessary to adjust the position and angle of the support rod 200 before installation, thus improving installation efficiency.

[0043] In some embodiments of the present invention, such as Figure 2 , Figure 4 and Figure 5 As shown, a plurality of first toothed grooves 110 are formed on the outer wall of the sleeve 100, and the plurality of first teeth are evenly distributed along the circumference of the sleeve 100; a plurality of second toothed grooves 410 are formed on the limiting device 400, and the plurality of second toothed grooves 410 are arranged in a one-to-one correspondence with the first toothed grooves 110; a toothed protrusion 510 matching the first toothed grooves 110 and the second toothed grooves 410 is formed on the inner wall of the sleeve buckle 500. Further, the diameter of the limiting device 400 is the same as the outer diameter of the sleeve 100.

[0044] In this embodiment of the invention, when the sleeve buckle 500 is in the unlocked state, the sleeve buckle 500 is sleeved on the sleeve 100, and the toothed protrusion 510 is completely located within the first toothed groove 110; when the sleeve buckle 500 is in the locked state, the sleeve buckle 500 is simultaneously sleeved on the sleeve 100 and the limiting device 400, and the two ends of the toothed protrusion 510 are respectively located within the first toothed groove 110 and the second toothed groove 410. In application, after adjusting the evacuation platform 300 to be level, the support rod 200 is rotated slightly to make the second toothed groove 410 correspond one-to-one with the first toothed groove 110. Then, the sleeve buckle 500 is moved so that the toothed protrusion 510 is inserted into the second toothed groove 410, locking the sleeve 100 and the support rod 200 together and preventing relative rotation between the sleeve 100 and the support rod 200.

[0045] In some embodiments of the present invention, such as Figure 2As shown, the top of the sleeve 100 is provided with a first pin hole 120 for detachable connection with the evacuation platform 300 via a pin. This design not only facilitates the installation and disassembly of the sleeve 100, but also allows the sleeve 100 to rotate around the pin during adjustment, making it convenient to adjust the angle of the support rod 200.

[0046] In some embodiments of the present invention, such as Figure 3 As shown, the positioning assembly 600 includes a sleeve 610, the inner wall of which is formed with a plurality of annular grooves 611, and the support rod 200 has an annular protrusion 210 located within the annular grooves 611; the annular grooves 611 and the annular protrusion 210 are loosely fitted. This arrangement facilitates the rotation of the support rod 200 around its axial direction; on the other hand, the fit between the annular grooves 611 and the annular protrusion 210 prevents the support rod 200 from disengaging from the sleeve 610.

[0047] Furthermore, a second pin hole 612 is formed on the sleeve 610 to allow for detachable connection with the tunnel inner wall via a pin. This design not only facilitates the installation and disassembly of the sleeve 610, but also allows the sleeve 610 to rotate around the pin during adjustment, making it convenient to adjust the angle of the support rod 200°.

[0048] In some embodiments of the present invention, a rotating support rod 700 is connected to the support rod 200, and the axial direction of the rotating support rod 700 is perpendicular to the axial direction of the support rod 200. Specifically, a through hole is formed on the support rod 200 through its axis, and a connecting rod 700 is connected to the support rod 200 through the through hole, so that the cooperation between the rotating support rod 700 and the support rod 200 forms a force-saving lever, allowing the user to easily rotate the support rod 200.

[0049] The technical solutions of the present invention have been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is not limited to these specific embodiments. Without departing from the technical principles of the present invention, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to related technical features.
