Description

Technical Field

[0001] This utility model relates to the field of railway technology and is used for the installation of pedestrian walkways on railways or bridges, specifically a pedestrian walkway fixing device. Background Technology

[0002] Pedestrian walkways are laid on the outside of railway tracks to serve as passageways for workers conducting inspections and maintenance. Traditionally, pedestrian walkways are made on-site using concrete or prefabricated reinforced concrete slabs. However, the limited installation space and high installation locations increase the difficulty of on-site fabrication. Using reinforced concrete slabs also requires placing them within railway walkway supports. Due to the weight of reinforced concrete slabs, transporting them to higher ground, such as on mountains, incurs significant manpower and transportation costs.

[0003] To address the aforementioned issues, existing technologies have introduced a fiberglass walkway body, which is a long strip. During installation, these strips are evenly spaced and fixed using connecting rods perpendicular to them, significantly reducing the weight of the walkway. However, due to the light weight of fiberglass, it is easily overturned. Therefore, during installation, the walkway body needs to be fixed, and the ends of adjacent walkway bodies need to be connected along its length. For example, patent CN104818673A discloses a railway bridge walkway, its installation structure, and installation method. This method uses materials such as fiber, woven fabric, and resin to manufacture the walkway through molding. Z-shaped seats are bonded to the bottom of the walkway to connect it to a T-shaped bridge installation walkway bracket, providing support. T-shaped steel clamps are used to connect the walkway along its length.

[0004] However, the aforementioned installation method for pedestrian pavers is complex due to the need for adhesive bonding, and requires moving the pavers or their supports to secure them, making installation inconvenient. Furthermore, the existing installation structure, which only uses Z-shaped brackets bonded to the bottom for fixation, is prone to instability and can easily be overturned by strong winds. Although existing technologies use T-shaped steel clamps at the pavers' joints, their direct connection to the pavers not only damages them but also results in insufficient stability at the joints because the T-shaped steel clamps are not secured to other components.

[0014] Preferably, the splicing parts of the two sets of horizontal plates can be spliced ​​into a whole, and the two splicing parts form a reserved groove at the splicing point, and the fixing member is placed in the reserved groove.

[0015] Compared with existing technologies, this utility model has the following advantages: By connecting the pressure block and the connecting piece, and the connecting piece and the walking board bracket, the walking board is limited and supported, making the installation of the walking board more stable and less prone to displacement. In particular, the support lugs on the upper part of the pressure block limit the walking board, making it less likely to be overturned in strong winds. At the same time, the snap-fit ​​connection makes the installation of the fixing device of this application more convenient and quick. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] A walking board fixing device, such as Figure 1-4 As shown, the system includes a pressure block 1 and a connector 2. The pressure block 1 restricts the displacement of the walking board 100; the connector 2 connects the pressure block 1 and the walking board support 200. The walking board 100 is positioned between the pressure block 1 and the connector 2, and the pressure block 1 and connector 2 limit the movement of the walking board 100 to prevent it from moving vertically or horizontally. The walking board support 200 provides support for the connector 2, the pressure block 1, and the walking board 100. The walking board 100 and the walking board support 200 are connected by the walking board fixing device, thus completing the installation of the walking board 100.

[0024] Specifically, the pressure block 1 includes a support lug 11, a support column 12, and a connecting block 13; the support lug 11 is located at the top of the support column 12, and the connecting block 13 is located at the bottom of the support column 12; the pressure block 1 is connected to the connector 2 via the connecting block 13. The walking board 100 is located between the support lug 11 and the connecting block 13. Specifically, the lower surface of the support lug 11 contacts the upper surface of the walking board 100, and the connecting block 13, in conjunction with the connector 2, limits the movement of the walking board 100; the support column 12 also restricts the forward and backward displacement of adjacent walking boards 100. The pressure block 1 is preferably integrally formed to improve its mechanical strength.

[0025] The connector 2 includes a horizontal plate 21, a first slot 22, and a second slot 23. The first slot 22 is located on the upper surface of the horizontal plate 21 and cooperates with the connecting block 13. The connection between the first slot 22 and the connecting block 13 establishes a fixed connection between the pressure block 1 and the connector 2. The second slot 23 is located on the lower surface of the horizontal plate 21 and matches the shape of the horizontal portion of the walking board support 200 to ensure a fixed connection between the connector 2 and the walking board support 200. Specifically, the second slot 23 can be designed as a C-shaped groove to accommodate the horizontal portion of the walking board support 200; preferably, the opening of the second slot 23 is parallel to the horizontal plate 21 to save installation space and make the installation more secure.

[0026] In this embodiment, the horizontal plate 21, the first slot 22, the second slot 23 and the fixing slot 242 in the connector 2 are preferably integrally formed to improve the physical properties of the connector 2.

[0027] Furthermore, the connector 2 also includes a fixing structure 24. The fixing structure 24 includes a fixing member 241 and a splicing part 242; the splicing part 242 is connected to the fixing member 241; the splicing part 242 is disposed in the horizontal plate 21, and the splicing part 242 is located at the end of the horizontal plate 21 away from the closed opening of the second slot 23. The connection between the splicing part 242 and the fixing member 241 makes the connection between the connector 2 and the walking board support 200 more stable.

[0028] When installing the walking board 100 using this fixing device, the connecting piece 2 is moved so that the walking board bracket 200 is inserted into the second slot 23. Then, the fixing structure 24 makes the connection between the connecting piece 2 and the walking board bracket 3 more stable. Next, along the length of the walking board 100, with the width of the support column 12 as the interval, two adjacent walking boards 100 are placed on the horizontal plate 21. Then, the pressure block 1 is pressed onto the upper surface of the walking board 100 so that the upper surface of the walking board 100 contacts the lower surface of the support lug 11, and the connecting block 13 is inserted into the first slot 22, so that the pressure block 1 and the connecting piece 2 are fixedly connected. It can be seen that when installing the walking board 100 using this fixing device, the installation of the walking board can be completed without the need for precise placement of the walking board 100, and the installation process is convenient and quick.

[0029] Example 2:

[0030] During the fixed installation of the walking board, to provide more stable support, two walking board supports 200 are usually arranged back-to-back, thus providing more stable support and fixation for the walking board. To connect the walking board 100 with the two walking board supports 200, this embodiment differs from Embodiment 1 in that the pressure block 1 includes two sets of connecting blocks 13, and the connecting member 2 includes two sets of horizontal plates 21, as shown... Figure 3 and Figure 4 As shown, two sets of horizontal plates 21 are symmetrically arranged on two walking supports 200.

[0031] Specifically, the pressure block 1 further includes a connecting plate 14, which is located at the bottom of the support column 12 and parallel to the lug 11; the connecting block 13 is located on the lower surface of the connecting plate 14. Preferably, two sets of connecting blocks 13 are symmetrically arranged on both sides of the support column 12. The two sets of first slots 22 on the two sets of horizontal plates 21 correspond to the positions of the two sets of connecting blocks 13, so that the connecting block 13 can be inserted into the first slot 22 to complete the fixing and limiting of the connector 2 and the pressure block 1.

[0032] During installation, the connector 2 is moved so that the horizontal parts of the two walking board supports 200 are respectively inserted into the second slots 23 on the two horizontal plates 21. Then, the positions of the two horizontal plates 21 are fixed by the fixing structure 24, thereby ensuring a more stable connection between the connector 2 and the walking board support 200. Next, the two sets of connecting blocks 13 in the pressure block 1 are respectively inserted into the corresponding first slots 22, so that the pressure block 1 and the connector 2 are fixedly connected. Finally, the walking board 100 is placed into the grooves formed on both sides of the support column 12, thereby completing the installation of the walking board 100.

[0033] Example 3:

[0034] The difference between this embodiment and embodiment 1 or 2 lies in the specific structure of the fixing structure 24.

[0035] When a single walking board support 200 is used as the support surface of the walking board, such as Figure 1 and 2 As shown, the splicing part 242 has a groove structure. The fixing member 241 is inserted into this groove structure, and the horizontal plate 21 is fixed by the fixing member 241 securing the vertical part of the walking board support 200, thereby preventing the connector 2 from shifting from the walking board support 200. Preferably, the fixing member 241 has a plate-like structure, and one side of the fixing member 241 is designed with a toothed structure, such as... Figure 5 As shown. At this time, the fastener 241 includes a protrusion 300 and a recess 400; during installation, the recess 400 of the fastener 241 is inserted into the groove of the splicing part 242 from above, thereby forming a connection between the fastener 241 and the horizontal plate 21. Then, the protrusion 300 of the fastener 241 restricts the movement of the connector 2 and the walking board support 200, thereby completing the fixation of the connector 2 and the walking board support 200.

[0036] When the double walking board bracket 200 is used as the support surface of the walking board, such as Figure 3 and 4 As shown, the fixing structure 24 fixes the two sets of horizontal plates 21 to prevent the connector 2 from shifting from the walking board support 200.

[0037] In one implementation, such as Figure 3 As shown, the fixing member 241 is a C-shaped groove, and the splicing part 242 is a groove structure. The horizontal plate 21 is fixed by inserting the two ends of the fixing member 241 into the grooves of the two splicing parts 242 in the two horizontal plates 21 respectively.

[0038] In another implementation, such as Figure 4 As shown, when installing the walking board using a double walking board bracket, the splicing portions 242 at the ends of the two sets of horizontal boards 21 can be spliced ​​together to form a whole. During splicing, a pre-reserved groove 243 is formed at the splicing point, which is created by the two splicing portions 242. After the two horizontal boards 21 are spliced ​​together, the fixing member 241 is pressed into the pre-reserved groove 243 to prevent the two horizontal boards 21 from shifting.
