Description

Technical Field

[0001] This invention belongs to the field of subway elevator installation technology, specifically a subway elevator installation structure. Background Technology

[0002] With the rapid development of urban rail transit, the demand for subway platform elevators, as important vertical transportation equipment, is increasing daily. Currently, subway elevator installation mostly adopts the traditional method of combining steel structure frames with concrete foundations. This technology has been used for many years and can meet basic load-bearing and stability requirements. However, with the increasing density of subway lines and the surge in passenger flow, elevator installation efficiency, seismic performance, and ease of subsequent maintenance have become the focus of industry attention.

[0003] During the installation of existing subway escalators, guardrails are specially installed on both sides. The core purpose of this design is to provide comprehensive protection for the stable and safe operation of the escalator, creating a reliable riding environment for passengers. Considering the convenience of transportation, the guardrails are not made of a single piece, but are composed of multiple panels spliced ​​together. In traditional technology, the splicing of adjacent panels is mostly accomplished by adhesive or welding.

[0004] However, the above installation methods have shortcomings. Regarding bonding, the adhesive gradually ages over time, and environmental factors such as temperature and humidity can easily lead to a significant decrease in adhesive strength, causing the connection between the panels to loosen. Welding, on the other hand, may suffer from unstable weld quality, such as porosity and cracks. These drawbacks of these splicing methods can make the joints between adjacent panels a safety hazard, potentially causing the panels to detach and exposing the elevator interior, threatening passenger safety. Furthermore, welding and bonding methods have very low tolerance for error, are cumbersome, and require professional skills and strict operating procedures. Moreover, subsequent maintenance, such as replacing panels, is extremely difficult. Therefore, a new installation structure for subway elevators is proposed. Summary of the Invention

[0005] To address the problems mentioned in the background section, the present invention provides a subway elevator installation structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a subway elevator installation structure, comprising an escalator body, wherein a main steel frame is fixedly connected to the bottom of the escalator body, and further comprising:

[0007] The outer skirt assembly is installed at the bottom and sides of the escalator body to protect the escalator body;

[0008] Stabilizing components, which are installed inside the outer skirt assembly, are used to support the outer skirt assembly;

[0009] The outer skirt panel assembly includes a side protective outer panel that abuts against the escalator body and multiple sets of first fixing female buckles that are fixedly connected to the main steel frame. A first fixing insert plate is inserted inside the first fixing female buckle.

[0010] The stabilizing component includes a connecting seat that is fixedly connected to the escalator body, and a damping rod is rotatably connected to the bottom of the connecting seat.

[0011] Preferably, the side protective outer plates are distributed on both sides of the escalator body and are fixedly connected to the escalator body by bolts, and a bottom protective outer plate is provided in the middle of a pair of side protective outer plates.

[0012] Preferably, the first fixing female buckle is fixedly connected to both sides of the vertical tube of the main steel frame, the first fixing plate is fixedly connected to the side protective outer plate and the bottom protective outer plate respectively, and the position of the first fixing plate corresponds to that of the first fixing female buckle, and the opening of the first fixing plate faces upward.

[0013] Preferably, the bottom protective outer plate has slots that are staggered at both ends, and a pair of adjacent bottom protective outer plates are inserted into each other, and a pair of second fixing female buckles are fixedly connected to the close ends of the pair of bottom protective outer plates.

[0014] Preferably, the openings of the second fixing female buckles all face the outer side of the bottom protective outer plate, and a second fixing plate is inserted into the middle of a pair of second fixing female buckles, the second fixing plate being bent.

[0015] Preferably, after the bottom protective outer plate is fixed to the middle of the main steel frame by inserting the first fixing plate and the first fixing nut, the slot on one side of the adjacent bottom protective outer plate is aligned with the fixed bottom protective outer plate and inserted. Then, the second fixing plate is pushed from the side into the second fixing nut on the adjacent side of the pair of bottom protective outer plates to fix the adjacent bottom protective outer plates.

[0016] Preferably, the damping rods are distributed on both sides of the main steel frame, and the bottom of the damping rods is fixedly connected to a connecting socket, the connecting socket having a trapezoidal limiting groove inside.

[0017] Preferably, the stabilizing component further includes a positioning protrusion fixedly connected to the side protective outer plate, a pair of fixing blocks are slidably connected inside the positioning protrusion, a pair of springs are fixedly connected in the middle of the pair of fixing blocks, and a compression block is slidably connected inside the positioning protrusion.

[0018] Preferably, the fixing block penetrates the positioning protrusion and extends to the outside of the positioning protrusion. The positioning protrusion is inserted into the inside of the connecting socket. The positioning protrusion is located in the middle of the side protective outer plate. The connecting socket is movably connected to an unlocking block in the middle. A pair of springs are fixedly connected to the upper end of the unlocking block.

[0019] Preferably, the connection socket has an opening that slopes downward toward the center, the bottom of the compression plug is wedge-shaped and tapers downward, the compression plug abuts against the opening in the center of the connection socket, and a second tension spring is fitted on the upper end of the compression plug.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] This invention facilitates the installation of the side and bottom protective panels on the outer side of the escalator body by using a combination of a first fixing nut, a first fixing insert, a second fixing nut, and a second fixing insert. The first fixing nut, fixedly connected to the outer side of the main steel frame, is inserted into the first fixing insert inside the side and bottom protective panels to ensure convenient and stable installation. Simultaneously, the second fixing nut and the second fixing insert in the middle of the bottom protective panel apply pressure, ensuring stability after assembly and preventing misalignment due to contact during subsequent installation. Furthermore, the fixed bottom protective panel can be adjusted at any time to maintain neatness during installation, reducing installation difficulty while improving efficiency and neatness. It also prevents subsequent installations from squeezing the currently installed bottom protective panel, causing misalignment or warping.

[0022] This invention, through the cooperation of stabilizing components and side protective panels, connects to the positioning protrusions via a connecting socket, allowing the damping rod to be installed and closed on the side protective panel. This applies a downward thrust to the bent portion of the side protective panel, ensuring that the lower end of the side protective panel, which is not fixed to the escalator body, is in a stable, pushed-and-pressed state. This prevents the lower side of the side protective panel from vibrating synchronously with the escalator body; the damping rod cancels out the vibration, preventing the side protective panel from vibrating and colliding with the escalator body and the bottom protective panel, thus avoiding the metallic clanging sound.

[0035] The technical solutions of 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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 7 As shown, the present invention provides a subway elevator installation structure, including an escalator body 100, a main steel frame 200 fixedly connected to the bottom of the escalator body 100, and further including:

[0037] The outer skirt assembly 300 is installed at the bottom and sides of the escalator body 100 to protect the escalator body 100.

[0038] Stabilizing component 400 is installed inside the outer skirt assembly 300 and is used to support the outer skirt assembly 300;

[0039] Among them, the outer skirt panel assembly 300 includes a side protective outer panel 301 that abuts against the escalator body 100 and multiple sets of first fixing female buckles 304 that are fixedly connected to the main steel frame 200. A first fixing insert plate 305 is inserted inside the first fixing female buckle 304.

[0040] The stabilizing component 400 includes a connecting seat 402 that is fixedly connected to the escalator body 100, and a damping rod 401 is rotatably connected to the bottom of the connecting seat 402.

[0041] The above solution is adopted: the bottom protective outer plate 302 is inserted and fixed by inserting the first fixing plate 305 on both sides of the bottom protective outer plate 302 and the first fixing nut 304, so as to complete the installation of the bottom protective outer plate 302. Then, the adjacent bottom protective outer plates 302 are fixed in sequence. When installing the bottom protective outer plate 302, the second fixing plate 303 is aligned with the second fixing nut 306 between the bottom protective outer plates 302 and inserted. The second fixing plate 303 applies pressure to the connection of the bottom protective outer plates 302 to fix the pair of bottom protective outer plates 302, so that the bottom protective outer plates 302 will not be misaligned due to contact during installation, which would affect the subsequent installation.

[0042] Then, the damping rod 401 is aligned and connected with the positioning protrusion 404 at the bend of the side protective outer plate 301, so that the damping rod 401 stabilizes the side protective outer plate 301 by pushing downward at an angle. The damping rod 401 supports the bottom of the side protective outer plate 301, avoiding the vibration generated by the side protective outer plate 301 when the escalator body 100 is running. This prevents the side protective outer plate 301 from shaking synchronously and colliding with the escalator body 100 and the bottom protective outer plate 302, thus generating noise and reducing the overall noise of the elevator during operation.

[0043] Specifically, the side protective outer plates 301 are distributed on both sides of the escalator body 100 and are fixedly connected to the escalator body 100 by bolts. A bottom protective outer plate 302 is provided in the middle of a pair of side protective outer plates 301.

[0044] The above solution is adopted: by setting up side protective outer panels 301 and bottom protective outer panels 302, the modular splicing design of side protective outer panels 301 and bottom protective outer panels 302 reduces the difficulty of production and transportation, and allows for targeted replacement after local damage, thereby improving the overall applicability.

[0045] Specifically, the first fixing female buckle 304 is fixedly connected to both sides of the vertical tube of the main steel frame 200, and the first fixing plate 305 is fixedly connected to the side protective outer plate 301 and the bottom protective outer plate 302 respectively. The first fixing plate 305 and the first fixing female buckle 304 are in opposite positions, and the opening of the first fixing plate 305 faces upward.

[0046] The bottom protective outer plate 302 has slots that are staggered at both ends, and a pair of adjacent bottom protective outer plates 302 are plugged into each other. A pair of second fixing female buckles 306 are fixedly connected to the close ends of a pair of bottom protective outer plates 302.

[0047] By adopting the above solution, the side protective outer plate 301 and the bottom protective outer plate 302 can be conveniently connected to the main steel frame 200 by insertion by setting the first fixing female buckle 304 and the first fixing insert plate 305. The first fixing female buckle 304 and the first fixing insert plate 305, which are distributed in pairs, facilitate the splicing of the modular side protective outer plate 301 and the bottom protective outer plate 302. Compared with the direct fixing with bolts, it is easier to adjust the misaligned parts. At the same time, when maintenance or replacement of part of the side protective outer plate 301 and the bottom protective outer plate 302 is required, the operation is convenient and the replacement difficulty is low. Setting the adjacent bottom protective outer plates 302 as plug-in can increase the stability by limiting the mutual position between the bottom protective outer plates 302.

[0048] Specifically, the openings of the second fixing female buckles 306 all face the outside of the bottom protective outer plate 302, and a second fixing plate 303 is inserted into the middle of a pair of second fixing female buckles 306. The second fixing plate 303 is bent.

[0049] After the bottom protective outer plate 302 is fixed to the middle of the main steel frame 200 by inserting the first fixing plate 305 and the first fixing nut 304, the slot on one side of the adjacent bottom protective outer plate 302 is aligned with the fixed bottom protective outer plate 302 and inserted. Then, the second fixing plate 303 is pushed from the side into the second fixing nut 306 on the adjacent side of the pair of bottom protective outer plates 302 to fix the adjacent bottom protective outer plates 302.

[0050] The above solution involves setting a second fixing nut 306 and a second fixing insert 303 to fix the bottom protective outer plate 302, thereby increasing the stability of the bottom protective outer plate 302. By setting the opening of the second fixing nut 306 to face the outside of the bottom protective outer plate 302, the pair of second fixing nuts 306 in the middle of the bottom protective outer plate 302 can be easily aligned with the adjacent bottom protective outer plate 302 after the second fixing insert 303 is inserted. At the same time, the second fixing insert 303 inserted between the pair of second fixing nuts 306 can squeeze the bottom protective outer plate 302 with its own bending force, so that the pair of bottom protective outer plates 302 are tightly pressed and stabilized under the condition that the first fixing nuts 304 limit them on both sides, thus avoiding misalignment of the bottom protective outer plate 302 during installation.

[0051] Specifically, damping rods 401 are distributed on both sides of the main steel frame 200, and a connecting socket 403 is fixedly connected to the bottom of the damping rods 401. A trapezoidal limiting groove is opened inside the connecting socket 403.

[0052] The stabilizing component 400 also includes a positioning protrusion 404 fixedly connected to the side protective outer plate 301. A pair of fixing blocks 405 are slidably connected inside the positioning protrusion 404. A pair of springs 406 are fixedly connected in the middle of the pair of fixing blocks 405. A compression block 407 is slidably connected inside the positioning protrusion 404.

[0053] The above solution is adopted: by setting a damping rod 401 and a connecting seat 402, the connecting seat 402 is fixed to the escalator body 100, so that the damping rod 401 can be rotated around the connecting seat 402 as the axis. In this way, the connecting seat 402 can be rotated to align with the bend of the side protective outer plate 301 during installation, so that the connecting socket 403 can be connected to the positioning protrusion 404.

[0054] By connecting the socket 403 to the positioning protrusion 404, the damping rod 401 is fixed to the side protective outer plate 301. This allows the damping rod 401 to be installed and closed on the side protective outer plate 301, applying a downward pushing force to the bend of the side protective outer plate 301. This keeps the lower end of the side protective outer plate 301, which is not fixed to the escalator body 100, in a stable state of being pushed and squeezed. When the escalator body 100 is running, the lower side of the side protective outer plate 301 will not vibrate synchronously with the vibration of the escalator body 100. The vibration will be canceled by the damping rod 401, so that the side protective outer plate 301 will not vibrate and collide with the escalator body 100 and the bottom protective outer plate 302, thus preventing the metal collision vibration sound.

[0055] Specifically, the fixing block 405 penetrates the positioning protrusion 404 and extends to the outside of the positioning protrusion 404. The positioning protrusion 404 is inserted into the connection socket 403. The positioning protrusion 404 is located in the middle of the side protective outer plate 301. The middle of the connection socket 403 is movably connected to the unlocking block (409). A pair of springs 4010 are fixedly connected to the upper end of the unlocking block 409.

[0056] The fixed insert 405 has an opening that slopes downward toward the center. The bottom of the compression insert 407 is a wedge shape that tapers downward. The compression insert 407 abuts against the opening in the center of the fixed insert 405. A second tension spring 408 is fitted on the upper end of the compression insert 407.

[0057] The above solution is adopted: by setting a fixing plug 405 and a pressing plug 407, the pressing plug 407 is pressed by the connecting socket 403 and moves into the positioning protrusion 404, thereby pressing the fixing plug 405 to move to both sides, so that the fixing plug 405 extends out from the positioning protrusion 404 and extends into the limiting groove inside the connecting socket 403 to fix the connecting socket 403. This avoids the connecting socket 403 from separating from the positioning protrusion 404 when the side protective outer plate 301 is fixed to the escalator body 100 with bolts, which would prevent the damping rod 401 from pushing the side protective outer plate 301 to stabilize it.

[0058] By using a second tension spring 408 provided on the compression plug 407, the compression plug 407 can be pulled away from the pair of fixed plugs 405 by the second tension spring 409 when it is no longer restrained, thereby releasing the fixed plugs 405 from the connection socket 403. Meanwhile, an unlocking block 409 provided in the middle of the connection socket 403... Figure 6 As shown, slots are provided on both sides of its bottom, so that the unlocking block 409 can be moved by pushing it from the side of the connecting socket 403, so that the inner slot of the unlocking block 409 is aligned with the fixed plug 405, thereby releasing the top of the fixed plug 405 from restriction.

[0059] Working principle and usage process of this invention:

[0060] During installation, the first fixing nut 304 is first fixed to both sides of the vertical tube of the main steel frame 200 with bolts at predetermined points. This facilitates the subsequent installation of the side protective outer plate 301 and the bottom protective outer plate 302. After the first fixing nut 304 is installed, the bottom protective outer plate 302 located at the bottom of the escalator body 100 is installed first. The first fixing inserts 305 on both sides of the bottom protective outer plate 302 are inserted into the first fixing nut 304 so that the bottom protective outer plate 302 is hooked in the middle of the main steel frame 200. Then, the adjacent bottom protective outer plates 302 are inserted and fixed in sequence.

[0061] After initially securing a pair of adjacent bottom protective outer plates 302 by inserting them into the first fixing nut 304, the adjacent bottom protective outer plates 302 need to be manually adjusted and aligned to ensure that both sides of the pair of adjacent bottom protective outer plates 302 are aligned. Then, the second fixing insert 303 needs to be aligned with the second fixing nut 306 between the bottom protective outer plates 302 from both sides, so that the bent second fixing insert 303 is fully inserted into the second fixing nut 306. At this point, the connection point of the pair of adjacent bottom protective outer plates 302 will be bent. The second fixing plate 303 applies pressure to the connection of the bottom protective outer plate 302, while the first fixing plates 305 on both sides of the bottom protective outer plate 302 are inserted into the first fixing female buckle 304, so that a pair of adjacent bottom protective outer plates 302 will not rotate around the connection point. At the same time, the pressure applied by the second fixing plate 303 makes the first fixing female buckle 304 on both sides of the bottom protective outer plate 302 precisely abut against the inner wall of the first fixing plate 305, so that the pair of bottom protective outer plates 302 remain fixed after alignment, and will not be misaligned due to contact during installation, which would affect subsequent installation.

[0062] After completing the installation of the bottom protective outer plate 302 from bottom to top, the side protective outer plates 301 located on both sides need to be installed. When installing the side protective outer plates 301, first install the side protective outer plate 301 located at the bottom of the escalator body 100. Move the side protective outer plate 301 horizontally toward the escalator body 100, and align the first fixing insert plate 305 inside the side protective outer plate 301 with the corresponding first fixing nut 304. When the side protective outer plate 301 moves close to the main steel frame 200, flip the damping rod 401 toward the bend of the side protective outer plate 301, so that the connecting socket 40 at the bottom of the damping rod 401... 3. Align with the positioning protrusion 404 and continue to push the side protective outer plate 301 toward the escalator body 100 until the first fixing plate 305 inside the side protective outer plate 301 is inserted into the first fixing female buckle 304 on the side of the main steel frame 200. At the same time, the positioning protrusion 404 in the middle of the side protective outer plate 301 will be inserted into the middle of the connecting socket 403. The unlocking block 409 inside the connecting socket 403 will push the pressing block 407 to move into the positioning protrusion 404. The pressing block 407 will press the fixing block 405 to open and extend out from the inside of the positioning protrusion 404, thereby fixing the connecting socket 403 and the positioning protrusion 404 by the buckle.

[0063] After the positioning protrusion 404 inside the side protective outer plate 301 is snapped and fixed to the connecting socket 403, the side protective outer plate 301 needs to be pushed to fit tightly against the escalator body 100 and fixed to the side of the escalator body 100 with bolts. At this time, the side protective outer plate 301 is fixed to the escalator body 100. At the same time, the bottom of the damping rod 401 abuts against the side protective outer plate 301 through the connecting socket 403, so that the damping rod 401 stabilizes the side protective outer plate 301 by pushing downward at an angle. The damping rod 401 supports the bottom of the side protective outer plate 301 to avoid the vibration generated by the side protective outer plate 301 during the operation of the escalator body 100, which would cause the side protective outer plate 301 to shake synchronously and collide with the escalator body 100 and the bottom protective outer plate 302, generating noise. At the same time, the stable side protective outer plates 301 on both sides will abut and limit the bottom protective outer plate 302 located in the middle, so that the bottom protective outer plate 302 remains in the center position.

[0065] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
