Description

Technical Field

[0001] This invention relates to the field of rail transit vehicle component technology, and in particular to a tread plate and a through passage having the tread plate. Background Technology

[0002] The connecting passageway for rail transit vehicles is located at the junction of two carriages, used to connect and connect the two carriages. It is a dynamic and important component of the rail vehicle. The connecting passageway is generally composed of components such as mounting frame, canopy, side guards, top plate, and treads. The treads of the connecting passageway are installed on the flat surface of the floor at the end of the car to form a safe connecting passageway floor. The three-piece treadway structure mainly includes a treadway and two steps. The two steps are fixedly connected to the two carriages respectively, and a linkage mechanism connects the two steps. The treadway is installed on the linkage mechanism using a locking mechanism. When the train is running, the connecting passageway must withstand conditions such as the train passing through horizontal curves, roll, pitch, and height differences. Under the action of the linkage, the treadway deflects and moves laterally. Under the action of the linkage mechanism, the treadway always remains in the middle position between the two steps, thus ensuring the sealing and safety of the floor passageway. Since the treadway and steps have relative movement during use due to the influence of vehicle operating conditions, they need to be disassembled and installed regularly for daily maintenance.

[0003] When disassembling a traditional three-piece tread plate structure, the locking mechanism needs to be operated on both sides of the tread plate to disassemble it. Therefore, it is necessary to first remove the side panels on both sides of the folding canopy, or if there is a folding canopy interior (with a folding canopy skirt), the folding canopy skirt needs to be separated to both sides. Then, two operators need to reach under the tread plate to operate the locking mechanism. This has the problem of poor installation and disassembly convenience. Moreover, this operation method is blind operation, which is not only very easy to injure hands, but also cannot see the locking pin of the locking mechanism on the linkage mechanism, making it impossible to effectively visually check the installation status of the tread plate, posing a safety hazard. Furthermore, during the installation process, because the position of the locking pin of the locking mechanism and the end mounting hole cannot be observed, it may be necessary to align the locking mechanism multiple times before the locking pin of the locking mechanism can be put into the mounting hole of the tread plate, which seriously affects the installation efficiency.

[0004] To address the aforementioned issue of ease of disassembly, existing technologies for three-piece flooring also include structures with convenient installation and disassembly of the transition plate. For example, Chinese Patent CN113942531B discloses a transition plate device for a passageway, which includes a transition plate, a transition plate linkage mechanism, and a locking mechanism. The transition plate has operating holes in its functional area. The locking mechanism includes a locking component mounted on the transition plate linkage mechanism, a locking component mounted on the bottom surface of the transition plate, and a rotating assembly mounted on the bottom surface of the transition plate. The rotating assembly's rotating operating component drives the rotating component to rotate between a first position and a second position. A pull member connects the rotating component and the locking component. An elastic locking component connects the locking component and the bottom surface of the transition plate. When the rotating component rotates to the first position, the locking component engages and locks the locking component under the elastic force provided by the elastic locking component. When the rotating component rotates to the second position, the pull member pulls the locking component to the unlocked state.

[0005] Although the installation and disassembly of the ramp device for the through passageway are carried out above the ramp, which is convenient and does not require the cooperation of many people, the locking mechanism still has the drawback of blind operation. The locking pin cannot be seen, and the locking status of the ramp locking mechanism cannot be visually inspected. Furthermore, under the elastic force of the elastic locking element, the locking box of the locking element and the engaging part of the locking element are always in contact during operation. The locking element is always subjected to the radial force transmitted by the locking element, which leads to abnormal wear of the locking element, shortens its life cycle, and consequently results in a high failure rate of the ramp device, requiring frequent repairs. Summary of the Invention

[0006] The purpose of this invention is to overcome the defects of the existing technology and provide a step plate that at least solves the problem of abnormal wear of the locking pin under continuous radial force.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The treadmill disclosed in this invention includes:

[0009] A ramp, a linkage mechanism disposed below the ramp and connected to the pedal, the linkage mechanism being equipped with a locking pin connected to the ramp;

[0010] The ferrule has a window corresponding to the locking pin position; and

[0011] Cover plate, which can be removed to seal the window; also includes

[0012] The mounting component is fixed to the lower surface of the slab and has a snap-fit ​​channel that communicates with the window and into which the locking pin can extend.

[0013] A snap-fit ​​component, which is installed in the snap-fit ​​channel through the window, has a snap-fit ​​component having a shaft clip that can be inserted into the shoulder of the locking pin to form a snap-fit ​​interface;

[0014] The card interface and the coupling part of the locking pin form an annular working area on the outer wall, so that when the linkage mechanism moves, the coupling part of the locking pin is linked in the annular working area and intermittently contacts the card interface to transmit the driving force for the lateral movement and deflection of the plate.

[0015] Furthermore, the shaft clip has a compensation section extending toward the bottom end of the coupling portion on the locking pin side, and a snap-fit ​​section formed at the end of the compensation section and extending toward the coupling portion;

[0016] The end of the snap-fit ​​section has an arc-shaped notch, so that after the snap-fit ​​sections of the two shaft clips are connected, the notch will surround and form the snap-fit ​​interface, and after the compensation section is connected, it will form a receiving groove that can accommodate the shaft shoulder.

[0017] Furthermore, the snap-fit ​​component also includes a connecting block, the upper part of which is detachably and fixedly connected to the shaft clip away from the locking pin end via a positioning component, and the lower surface of the connecting block is fixedly connected to the mounting component.

[0018] Furthermore, the mounting component includes a mounting beam extending along the length of the slab, the mounting beam having a snap-fit ​​channel corresponding to the locking pin position, and the mounting beam having a groove structure corresponding to the window position, the groove structure being connected to the snap-fit ​​channel.

[0019] Furthermore, the mounting component also includes support beams symmetrically arranged on both sides of the mounting beam. The support beams have a bearing surface that contacts the lower surface of the cover plate at the window position. The bearing surface is fixedly connected to the cover plate through a disassembly structure.

[0020] Furthermore, the disassembly structure includes connecting holes formed on the support beam and connecting components;

[0021] The cover plate has mounting holes on both sides;

[0022] The connector passes through the mounting hole and the window in sequence and connects to the connection hole.

[0023] Furthermore, the support beam is a hollow beam, and an inner beam of the same length is inserted inside the support beam. The upper surface of the support beam has a first through hole and the lower surface has a second through hole. The inner beam has a connecting hole corresponding to the first through hole and the second through hole. One end of the inner beam has a process hole.

[0024] Furthermore, one end of the support beam is fixedly connected to the mounting beam, and the other end extends along the width direction of the truss plate and forms a free end. Both sides of the support beam are fixedly connected to the truss plate.

[0025] Furthermore, both ends of the linkage mechanism are connected to the pedals, and the pedals are located on the side of the ferrule and are connected by hinges to a movable pedal that can be flipped and extended under the ferrule to overlap with the ferrule.

[0026] The through passage disclosed in this invention includes: the aforementioned stepping board.

[0027] In the above technical solution, the present invention provides a stepping board and a through channel having the stepping board, which have the following advantages:

[0028] Compared with the prior art, the step plate designed in this invention has a window opened at the locking pin position of the linkage mechanism, and a mounting component is fixedly connected to the lower part of the step plate. The mounting component has a snap-fit ​​channel that communicates with the window and allows the locking pin to extend into it. The snap-fit ​​component is installed in the snap-fit ​​channel through the window. The two shafts of the snap-fit ​​component snap together to form a snap-fit ​​interface. The snap-fit ​​interface and the outer wall of the coupling part of the locking pin form an annular working area. Through the annular working area, the snap-fit ​​component and the locking pin make intermittent contact to transmit the force that drives the lateral movement of the step plate to adjust the attitude of the step plate. This effectively solves the problem of abnormal wear caused by the continuous radial force on the locking pin, and achieves the purpose of extending the service life of the locking pin and reducing the overall failure rate of the step plate.

[0029] Secondly, the window not only allows observation of the locking pin, but also allows the shaft clip of the snap-fit ​​component to be installed in the snap-fit ​​channel through the window. The entire installation process is visible and can be directly observed above the transition plate to ensure the successful installation of the transition plate and effectively eliminate safety hazards.

[0030] The through passage designed in this invention has the aforementioned stepping board, which has the same beneficial effects as the stepping board, and will not be described in detail here. Attached Figure Description

[0049] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0050] See Figure 1-3 As shown;

[0051] An invention includes a ferry board, comprising: ferry board 1, linkage mechanism 2, and pedal 3;

[0052] The linkage mechanism 2 is located below the skid plate 1. The end of the linkage mechanism 2 is hinged to the pedal 3 via a shaft. The middle part of the linkage mechanism 2 is equipped with a locking pin 21 that is connected to the skid plate 1.

[0053] Among them, the ramp 1 has a window 11 at the position corresponding to the locking pin 21; and

[0054] Cover plate 4, which can be removed to cover window 11; also includes

[0055] Mounting component 5 is fixed to the lower surface of the truss plate 1 and has a snap-fit ​​channel 512 that communicates with the window 11 and into which the locking pin 21 can extend.

[0056] The snap-fit ​​component 6 is installed in the snap-fit ​​channel 512 through the window 11. The snap-fit ​​component 6 has a shaft clip 62 that can be inserted into the shaft shoulder 211 of the locking pin 21 to form a snap-fit ​​interface.

[0057] The outer wall of the coupling part 212 between the card interface and the locking pin 21 forms an annular working area 63, so that the linkage mechanism 2 moves, the coupling part 212 of the locking pin 21 moves in conjunction with the card interface and intermittently contacts the card interface to transmit the driving force for the transverse movement and deflection of the driving plate 1.

[0058] For details, see Figure 3 As shown, the snap-fit ​​component 6 has two shaft clips 62. The two shaft clips 62 are installed in the snap-fit ​​channel 512 through the window 11. After the two shaft clips 62 are mated, they form a snap-fit ​​interface. The diameter of the snap-fit ​​interface is smaller than the diameter of the shoulder 211 of the locking pin 21 to prevent the snap-fit ​​component 6 from detaching from the shoulder 211 end of the locking pin 21. The inner wall of the snap-fit ​​interface and the outer wall of the coupling part 212 of the locking pin 21 form an annular working area 63.

[0059] In operation, the linkage mechanism 2 moves under the influence of the train's operating conditions and drives the locking pin 21 to transmit force. When the train is running smoothly, the ramp 1 is in the correct position and is used. At this time, the coupling part 212 of the locking pin 21 can move in the annular working area 63 without contacting the card interface, thereby reducing the wear between the locking pin 21 and the axle card 62 and extending the service life of the axle card 62 and the locking pin 21. When the train is in adverse conditions such as passing through horizontal curves, side roll, pitch, and height difference, the linkage mechanism 2 moves with the train and contacts the inner wall of the card interface through the outer wall of the coupling part 212 of the locking pin 21, thereby pushing the ramp 1 to move laterally and deflect to adjust its posture, so that it always maintains a safe through passage floor passage.

[0060] In this structure, the plate 1 uses the mounting part 5 to provide a snap-fit ​​channel 512 for mounting the snap-fit ​​part 6, so that the locking pin 21 is placed in the snap-fit ​​channel 512. The snap-fit ​​interface formed by the shaft clip 62 of the snap-fit ​​part 6 and the outer wall of the coupling part 212 of the locking pin 21 form an annular working area 63. The annular working area 63 is used to make the snap-fit ​​part 6 and the locking pin 21 intermittently contact to transmit the force driving the plate 1 to move, thereby adjusting the posture of the plate 1. This effectively solves the problem of abnormal wear caused by the continuous radial force on the locking pin 21. In addition, the plate 1 has a window 11 corresponding to the position of the locking pin 21. Through the window 11, not only can the locking pin 21 be observed, but the shaft clip 62 of the snap-fit ​​part 6 is also installed in the snap-fit ​​channel 512 through the window 11. The locking state of the locking pin 21 and the snap-fit ​​part 6 can be directly observed from above the plate 1, ensuring the successful installation of the plate 1 and eliminating safety hazards.

[0061] See Figure 3 As shown:

[0062] For redundancy design and to meet various operating conditions during train operation, the axle clip 62 has a compensation section 621 extending toward the bottom end of the coupling portion 212 on the side of the locking pin 21, and a snap-fit ​​section 622 formed at the end of the compensation section 621 and extending toward the coupling portion 212. The snap-fit ​​section 622 has an arc-shaped notch 623 at its end (e.g., Figure 9 As shown), after the snap-fit ​​sections 622 of the two shaft clips 62 are connected, the notch 623 surrounds to form a snap-fit ​​interface, and after the compensation section 621 is connected, it forms a receiving groove 64 that can accommodate the shaft shoulder 211, so as to avoid mechanical interference between the shaft shoulder 211 and the shaft clip 62 when it moves. During operation, the shaft shoulder 211 can approach the upper surface of the snap-fit ​​section 622 or protrude from the upper surface of the shaft clip 62, that is, the working state in which the linkage mechanism 2 drives the locking pin 21 to float up and down.

[0063] See Figure 4-7 As shown:

[0064] The snap-fit ​​component 6 also includes a connecting block 61. The upper part of the connecting block 61 is detachably and fixedly connected to the end of the shaft clip 62 away from the locking pin 21 via a positioning component 65. The lower surface of the connecting block 61 is fixedly connected to the mounting component 5. See [link to documentation]. Figure 3As shown, during maintenance, the positioning component 65 between the connecting block 61 and the shaft clip 62 is disassembled, the connecting block 61 and the shaft clip 62 are disassembled, the shaft clip 62 is disassembled separately and the shaft clip 62 is taken out through the window 11 of the transition plate 1 to unlock the locking pin 21. This not only realizes the separation of the linkage mechanism 2 from the transition plate 1 and the smooth disassembly of the transition plate 1, but also the shaft clip 62 is the smallest replaceable unit, and the shaft clip 62 can be replaced separately when damaged. In this structure, the positioning component 65 is an internal hexagon countersunk head screw in the prior art. The connecting block 61 has a threaded hole for threaded connection with the screw, and the tail end of the shaft clip 62 has a through hole through which the screw can pass. The bottom of the connecting block 61 has a threaded hole, which is detachably fixedly connected to the mounting component 5 through the connecting component 67. The connecting block 61 can be pre-assembled on the mounting component 5. The connecting component 67 is an internal hexagon countersunk head screw.

[0065] See Figure 8 As shown, another preferred embodiment is basically the same as the above embodiment, except that the snap-fit ​​component 6 also includes a top block 66. The upper part of the connecting block 61 abuts against the lower surface of the shaft clip 62 away from the locking pin 21. The cover plate 4 is fixedly connected to the mounting component 5. One end of the top block 66 abuts against the upper surface of the shaft clip 62 and the other end abuts against the cover plate 4, thereby fixing the shaft clip 62 to the upper surface of the connecting block 61 through the top block 66, so that the shaft clip 62 and the connecting block 61 can be separated when the cover plate 4 is removed.

[0066] See Figure 3 As shown:

[0067] Mounting component 5 includes a mounting beam 51 extending along the length of the transition plate 1. The mounting beam 51 has a snap-fit ​​channel 512 corresponding to the locking pin 21, and a groove structure 511 is formed within the horizontal projection area of ​​the window 11 corresponding to the mounting beam 51. The snap-fit ​​component 6 is mounted through the groove structure 511. (See also...) Figure 7 As shown, the mounting beam 51 is a hollow beam with a U-shaped or square cross-section. In order to reduce the weight of the ferrule 1, the mounting beam 51 is preferably a U-shaped hollow beam. The top of the U-shaped hollow beam is fixedly connected to the lower surface of the ferrule 1 by welding. The mounting beam 51 forms a groove structure 511 at the position corresponding to the window 11. The bottom wall of the groove structure 511 is provided with a snap-fit ​​channel 512 so that the locking pin 21 can penetrate into the groove structure 511 and snap-fit ​​with the snap-fit ​​piece 6.

[0068] See Figure 7 As shown:

[0069] Mounting component 5 also includes support beams 52 symmetrically arranged on both sides of mounting beam 51. Support beams 52 have bearing surfaces that contact the lower surface of cover plate 4 at positions corresponding to windows 11. These bearing surfaces are fixedly connected to cover plate 4 via a disassembly structure. In this structure, mounting component 5 provides an installation interface for cover plate 4 through support beams 52. Support beams 52 contact the lower surface of cover plate 4 through their bearing surfaces and are fixedly connected to cover plate 4 via a disassembly structure, ensuring the reliability of cover plate 4 installation. Furthermore, the support beams 52 support cover plate 4, making the upper surface of cover plate 4 coplanar with the upper surface of the ramp 1, preventing cover plate 4 from protruding and tripping people passing through the passageway, and avoiding aesthetic concerns. The structure of cover plate 4 is adapted to the shape of window 11, which can be rhomboid, square, circular, triangular, etc., and the outline of cover plate 4 is adapted to the shape of window 11.

[0070] See Figure 7 As shown:

[0071] Preferably, the disassembly structure includes a connecting hole 531 on the support beam 52 and a connector 41. The cover plate 4 has mounting holes on both sides. The connector 41 passes through the mounting hole and the window 11 in sequence and connects to the connecting hole 531, thereby fixing the cover plate 4 to the support beam 52 and preventing the cover plate 4 from being lost during use. The connector 41 is an internal hexagon countersunk screw, and the connecting hole 531 is a threaded hole.

[0072] See Figure 7 As shown:

[0073] The support beam 52 is a hollow beam, specifically a hollow square beam. An inner beam 53 of equal length is inserted inside the support beam 52. The support beam 52 has a first through hole 521 on its upper surface and a second through hole 522 on its lower surface. The inner beam 53 has a connecting hole 531 corresponding to the positions of the first and second through holes 521 and 522. One end of the inner beam 53 has a process hole 532 (e.g., ...). Figure 10 As shown), the process hole 532 is a threaded hole, which is threaded to the bolt, making it easy to remove the inner beam 53 from the support beam 52 and to replace the inner beam 53 in a timely manner. The inner beam 53 is the smallest detachable unit. A connection hole 531 is opened on the inner beam 53 to provide an installation interface for the cover plate 4, so as to avoid the problem that the installation interface of the cover plate 4 is damaged and cannot be easily repaired on site, resulting in increased costs due to the need to return to the factory for cutting and replacement.

[0074] During assembly, the inner beam 53 is first assembled inside the support beam 52. The connector 54 passes through the second through hole 522 of the support beam 52 and connects to the connecting hole 531 at the bottom of the inner beam 53. When installing the cover plate 4, the connector 41 passes through the first through hole 521 and connects to the connecting hole 531 on the upper surface of the inner beam 53, thereby fixing the cover plate 4 on the inner beam 53. It should be noted that the connector 54 is a countersunk hexagonal screw. When the inner beam 53 needs to be replaced, the inner beam 53 is the same length as the support beam 52. The inner beam 53 can be replaced by screwing a bolt that matches the process hole 532 at the end of the inner beam 53 into the process hole 532 and pulling out the inner beam 53.

[0075] Of course, the disassembly structure can also be a magnet. A magnet is fixed to the bearing surface of the support beam 52. The cover plate 4 is fixed by the magnet. The structure is simple and easy to disassemble and assemble. It should be noted that when the disassembly structure is a magnet, the connecting block 61 and the shaft clip 62 of the snap-fit ​​part 6 are fixedly connected by internal hexagonal head screws.

[0076] See Figure 7 As shown:

[0077] One end of the support beam 52 is fixedly connected to the mounting beam 51, and the other end extends along the width direction of the truss plate 1 and forms a free end. Both sides of the support beam 52 are fixedly connected to the truss plate 1. In this structure, the support beam 52, the mounting beam 51, and the truss plate 1 are fixedly connected by welding. The fixed connection of one end of the support beam 52 to the mounting beam 51 not only makes the support beam 52 rooted on the mounting beam 51, ensuring the reliability of the support, but also, the fixed connection between the mounting beam 51 and the truss plate 1 through the support beam 52 effectively improves the connection strength between the mounting component 5 and the truss plate 1, and also improves the overall structural strength of the truss plate 1, which is conducive to extending the service life of the truss plate 1.

[0078] See Figure 1 As shown:

[0079] Both ends of the linkage mechanism 2 are connected to pedals 3 via shafts. The pedals 3 are located on the side of the ferrule 1 and are connected by hinges to a movable pedal that can be flipped and extended under the ferrule 1. The movable pedal is connected to the ferrule 1. Both ends of the ferrule are hinged to foldable wing plates 12.

[0080] The invention includes: a mounting frame, a folding canopy, side guards, a top plate, and the aforementioned step plate. The passageway is connected between two carriages through the folding canopy to form a sealed passageway. The step plate is installed on the upper surface of the carriage end floor plate at the lower part of the folding canopy to form the passageway floor passageway.

[0081] In the above technical solution, the present invention provides a treadmill and a treadmill installation method:

[0082] Step 1: Prepare the ferrule 1, loosen the hexagon countersunk screws on both sides of the middle cover plate 4 of the ferrule 1, remove the two cover plates 4, loosen the hexagon countersunk screws on the shaft clips 62, and take out the four shaft clips 62 for later use.

[0083] Step 2: Insert one side of the transfer board 1 diagonally into the lower part of the inner folding canopy decorative skirt, tilting it to one end to make it easier to gradually flatten the other end. Open the bottom decorative skirt of the inner folding canopy and place the transfer board 1 flat between the two pedals 3.

[0084] Step 3: Observe the position of the snap-fit ​​channel 512 and the locking pin 21 on the lower mounting beam 51 through the window 11 on the cross plate 1, and adjust and position the locking pin 21 in the center of the snap-fit ​​channel 512.

[0085] Step 4: Insert the previously removed shaft clip 62 into the groove structure 511 of the mounting beam 51 and fix it to the connecting block 61 of the clip 6 with hexagonal head screws, spring washers, and flat washers. At this time, the clip section 622 of the shaft clip 62 extends into the lower part of the shaft shoulder 211 of the locking pin 21. The two shaft clips 62 are connected, and the notch 623 forms a clip interface. When the locking pin 21 transmits force, the coupling part 212 of the locking pin 21 intermittently contacts the shaft clip 62 in the annular working area 63 of the clip interface to transmit force.

[0086] Step 5: Place the cover plate 4 back into window 11 and tighten it with hex socket countersunk screws. Installation is complete.

[0087] The tread plate provided by this invention has a disassembly method that is the reverse of the installation method, and will not be described in detail here.

[0088] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
