Description

Technical Field

[0001] This utility model relates to the field of rail transit, and in particular to a support block and pre-assembly platform for a pre-assembly platform for a car body under-groove. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] The rail vehicle has electrical wires at the bottom, which are usually installed in the undercarriage cable trays. To facilitate the installation of these undercarriage cable trays, a pre-assembly platform is set up. This platform is used to install the entire central cable tray onto the vehicle body. The cable trays need to be placed on the supports of a 14-meter steel platform beforehand. During the installation of the cable trays and the vehicle seat, because there are accessories at the bottom of the cable trays, the bottom of the cable trays cannot directly contact the steel platform. Supports need to be added to the steel platform to lift the bottom of the cable trays, making it easier for them to connect to the vehicle body mounting base. After the cables are laid out in the cable trays, a three-linkage lifting vehicle is used to lift the platform and cable trays together. After the cable trays are installed, the steel platform and supports are returned to their original positions.

[0004] The inventors discovered that existing support blocks are single-form T-blocks, the wire grooves on their surface are prone to slipping, the fixation is unreliable, and the support blocks are usually welded to a steel platform, so the position is not adjustable; In addition, because there is a skirt mounting seat on the underside of the rail vehicle, and the skirt mounting seat is close to the cable trough, the cable trough needs to be connected to the skirt mounting seat. During the process of lifting the cable trough upward, there is some interference between the two, which makes it impossible for the pre-assembled platform to be raised and lowered into place. Manual installation with tools such as pry bars is required, which is time-consuming and labor-intensive. Utility Model Content

[0030] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise expressly indicated by the present invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. As described in the background section, the support blocks of the pre-assembled platform in the prior art cannot guarantee the stability of the cable tray and are prone to interference with the skirt plate mounting seat during the lifting of the cable tray. In order to solve the above technical problems, this utility model proposes a support block, floor support component and double-decker rail transit vehicle for the pre-assembled platform of the cable tray under the vehicle body.

[0032] Example 1 In a typical embodiment of this utility model, refer to Figure 1 and Figure 2 As shown, a support block for a pre-assembly platform for a lower wiring trough of a vehicle body includes a support body 1 with a set thickness. The upper side of the support body 1 is provided with a support groove 2 to fit the wiring trough 7. The support body 1 has a skirt placement groove 4 on one side of the support groove 2. The other side of the support body 1 relative to the support groove 2, i.e., the lower side of the support body 1, is provided with a protrusion. The protrusion is inserted into the pre-assembly platform and is movable relative to the pre-assembly platform.

[0033] It should be noted that the support body 1 forms a protrusion on the bottom side of the support body by opening slots 5 on both sides of the support body.

[0034] In some examples, to broaden the application range of the support body, locking blocks 6 are respectively set on both sides of the protrusion. The locking blocks 6 are located at the corner of the slot 5 and are close to the support slot 2, so that the non-locking area of ​​the protrusion can be locked into the first size pre-assembled platform. The locking blocks enable the protrusion to be locked into the second size pre-assembled platform.

[0035] To ensure the stability of the locking block 6 after it is engaged with the pre-assembled platform, the side of the locking block 6 away from the support body 1 is a sloping structure. The locking block 6 is wider at the top and narrower at the bottom. In other words, the locking block 6 ensures the stability of the support body 1 after it is engaged with the pre-assembled platform. The setting of the locking block 6 allows the support block to be used with pre-assembled platforms of different widths, which improves flexibility. The design is simple and novel and highly practical.

[0036] Considering the trapezoidal shape of the cable tray, and to match the shape of cable tray 7, the shape of the support tray 2 is an inverted trapezoid. A short support side 3 is provided on the side of the support tray 2 closest to the skirt board placement tray 4. The purpose of the short support side 3 is to avoid the skirt board mounting seat 8. A long support side is provided on the other side of the support tray 2 away from the skirt board placement tray 4. The height of the long support side is greater than the height of the short support side 3. The short support side 3 separates the support tray 2 from the skirt board placement tray 4. The height of the short support side is reasonably set so that it effectively avoids the skirt board mounting seat 8 when the pre-assembly platform pushes the cable tray toward the skirt board mounting seat.

[0037] Considering that the sides and bottom of the skirt board mounting base 8 are both straight, in order to match the shape of the skirt board mounting base 8, the top of the skirt board placement groove 4 and one side of the short support edge 3 are both open. The sides of the skirt board placement groove 4 are all straight. The side of the short support edge 3 near the skirt board placement groove 4 is straight, and the other side of the short support edge 3 near the skirt board placement groove 4 is a bevel.

[0038] Considering the depth of the skirt board mounting base 8, the depth of the skirt board placement groove 4 is greater than the height of the short support side 3 facing the support groove side, and the width of the skirt board placement groove 4 is greater than the width of the skirt board mounting base 8. When the support block support groove 7 contacts the skirt board mounting base 8, the bottom surface of the skirt board placement groove 4 does not need to contact the skirt board mounting base 8, as long as space is left for the skirt board mounting base 8 through the skirt board placement groove 4.

[0039] The support block provided in this embodiment is referenced. Figure 3 As shown, the support block includes a support body 1. The support body 1 is provided with a lifting groove 2 to support the wire groove 7 and prevent the wire groove 7 from slipping off the support block. A skirt plate placement groove 4 is provided on one side of the support body 1, so that the support block can effectively avoid the skirt plate mounting seat 8 during the movement of the support block with the pre-assembly platform, ensuring that the support block supports the wire groove 7 in place. The support body 1 is provided with a protrusion that can be inserted into the pre-assembly platform and is movable relative to the pre-assembly platform, so as to facilitate the adjustment of the position of the support body on the pre-assembly platform.

[0040] Example 2 This embodiment provides a pre-assembly platform for the lower wiring harness of a vehicle body, referring to... Figure 4 As shown, the system includes a platform body 9, which has an open slot. Multiple support blocks for the pre-assembled platform of the vehicle body lower wiring groove described in Embodiment 1 are installed in the open slot. The support blocks are spaced apart.
