[0002] Railway general-purpose flatcars are divided into two types: ordinary flatcars and shared flatcars. Ordinary flatcars generally have wooden or steel floors throughout their length and are used to transport steel coils, metal ingots, automobiles, large machinery and equipment, large precast concrete beams, and military equipment. Shared flatcars, in addition to their ordinary functions, also need to be able to transport containers. Container locking devices are welded onto the flatcars to position and reinforce the containers to ensure safe transportation. Therefore, shared flatcars typically have holes in the floor for these locking devices, and the locks in the locking devices must be raised above the floor surface to position and reinforce the containers.

[0003] The container locking device is usually fixed to the chassis of the vehicle body through a locking mounting base. The locking mounting base usually has a pallet. The container locking device is fixed to the pallet. The pallet is generally fixed on the chassis and supported by the beams of the chassis.

[0042] The core of the utility model is to provide a locking mounting seat installation structure, so that after the locking mounting seat is installed, the flatness of the vehicle body floor can be maintained.

[0043] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the components described in the following embodiments are not necessarily required to provide the solutions described in the claims. It should be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings. The embodiments and features of the embodiments of the present utility model may be combined with one another unless there is a conflict.

[0044] The locking mounting seat installation structure disclosed in the embodiment of the utility model can keep the vehicle floor flat after the locking mounting seat is installed.

[0045] like Figure 1-Figure 3 As shown, the locking mounting seat is installed on the vehicle body chassis, and the locking mounting seat includes at least one of a single lock seat 100 and a double lock seat 200. The single lock seat 100 is used to install one container locking device 300, and the double lock seat 200 is used to install two container locking devices 300.

[0046] Single lock seats 100 are installed at the four corners of the vehicle body chassis, and double lock seats 200 are installed in the middle of the vehicle body chassis. One vehicle body can simultaneously carry two 20ft containers and one 40ft container. When two 20ft containers are loaded simultaneously on a vehicle body, one end of one 20ft container is secured by the container locking device 300 on the two single lock seats 100 at the first end of the vehicle body and the container locking device 300 on the two middle double lock seats 200 near the first end; one end of the other 20ft container is secured by the container locking device 300 on the two single lock seats 100 at the second end of the vehicle body and the container locking device 300 on the two middle double lock seats 200 near the second end. The 40ft container is secured by the container locking devices 300 on the single lock seats 100 at the four end corners of the vehicle body.

[0047] like Figure 1 and Figure 4 As shown, the single lock seat 100 includes a single lock support plate 101 and a single lock belly plate 102 arranged on the lower side of the single lock support plate 101. A first flip avoidance hole 104 is opened at the position where the single lock support plate 101 is installed with a container locking device 300. That is, since the single lock support plate 101 only needs to install one container locking device 300, only one first flip avoidance hole 104 needs to be opened.

[0048] One end of the single lock seat 100 is connected to the web of the side beam 1 of the vehicle body chassis via a single lock web 102, and the other end is connected to the vertical surface of the longitudinal beam 3 of the vehicle body chassis. The single lock support plate 101 is located below the upper pad of the side beam 1. Specifically, the end surface of the single lock web 102 can be welded to the web of the side beam 1, and the end surface of the single lock support plate 101 and the end surface of the single lock web 102 can be coplanar. During welding, the single lock support plate 101 and the single lock web 102 can be welded together to the web of the side beam 1. The other end of the single lock web 102 can also be welded to the vertical surface of the longitudinal beam 3. If the other end of the single lock web 102 and the corresponding end of the single lock support plate 101 are also coplanar, the single lock support plate 101 and the single lock web 102 can also be welded together to the vertical surface of the longitudinal beam 3 during welding.

[0049] like Figure 2 and Figure 5 As shown, the double lock base 200 includes a double lock support plate 201, a double lock transverse rib 202 disposed in the middle of the lower side of the double lock support plate 201, and double lock vertical ribs 203 connected to both sides of the double lock transverse rib 202. The double lock support plate 201 is provided with a second tilt avoidance hole 204 at the location where the two container locking devices 300 are mounted. Specifically, the double lock support plate 201 has two second tilt avoidance holes 204, which are symmetrically arranged along the double lock transverse rib 202. The two double lock vertical ribs 203 can also be symmetrically arranged along the double lock transverse rib 202. It should be noted that the double lock vertical ribs 203 should avoid the second tilt avoidance holes 204. The double lock vertical ribs 203 can be arranged perpendicularly to both the double lock transverse rib 202 and the double lock support plate 201. Of course, the angle between the three can also be designed as needed and is not limited to perpendicularity.

[0050] The double-lock transverse rib 202 is connected to the web of the side sill 1, the double-lock vertical rib 203 is connected to the web of the central cross member 4 of the vehicle body chassis, and the double-lock support plate 201 is located below the upper pad of the central cross member 4. Specifically, the double-lock transverse rib 202 can be connected to the web of the side sill 1 by welding. If the end surfaces of the double-lock support plate 201 and the double-lock transverse rib 202 can be coplanar, the double-lock support plate 201 and the double-lock transverse rib 202 can be welded together to the web of the side sill 1. The double-lock vertical rib 203 can also be connected to the web of the central cross member 4 by welding.

[0051] In the locking mounting structure disclosed in the embodiment of the present invention, a single lock base 100 is connected to the web of the side beam 1 of the vehicle chassis via its single lock web 102. The other end of the single lock web 102 is connected to the vertical surface of the vehicle chassis's longitudinal beam 3. The single lock base 100 does not require the single lock support plate 101 to be supported on the backing plate of the crossbeam. Instead, the single lock base 100 is secured by connecting the single lock web 102 to the web of the side beam 1 and the vertical surface of the longitudinal beam 3. This allows the single lock support plate 101 to be positioned below the upper backing plate of the side beam 1, and subsequently below the vehicle floor (the vehicle floor is laid on the vehicle chassis).

[0052] The double lock seat 200 is connected to the web of the side beam 1 via the double lock transverse rib 202, and to the web of the central cross beam 4 via the double lock vertical rib 203. The double lock seat 200 does not require the double lock support plate 201 to be supported on the cross beam pad. Instead, the double lock seat 200 is fixed by connecting the double lock transverse rib 202 to the web of the side beam 1, and the double lock vertical rib 203 to the web of the central cross beam 4. This allows the double lock support plate 201 to be located below the upper pads of the side beam 1 and the central cross beam 4, and then below the vehicle body floor.

[0053] The mounting structure of this utility model allows both the single lock seat 100 and the double lock seat 200 to be installed below the vehicle floor plane, ensuring that the upper surface of the container locking device 300 does not exceed the upper surface of the vehicle floor after installation, meeting the requirement of reducing the load-bearing surface height. The single lock seat 100 and the double lock seat 200 of this utility model do not require changes to the structural design of the chassis crossbeam and can be independently assembled in a suitable location, resulting in a reliable structure and convenient assembly.

[0054] like Figure 1 and Figure 4 As shown, in this embodiment, to improve the support strength and load-bearing capacity of the single lock seat 100, the single lock seat 100 may further include a single lock rib 103. There are two single lock webs 102, one located on either side of the first tilt avoidance hole 104, and the single lock rib 103 is connected between the two single lock webs 102. In this embodiment, by connecting the single lock rib 103 between the two single lock webs 102, the stability of the two single lock webs 102 can be improved. Furthermore, multiple single lock ribs 103 may be provided, that is, at least two, and a single lock rib 103 is provided at both ends of the first tilt avoidance hole 104. For example, in the case of two single lock ribs 103, one single lock rib 103 is provided on the outside of one end of the first tilt avoidance hole 104, and the other single lock rib 103 is provided on the outside of the other end of the first tilt avoidance hole 104. In this embodiment, the single lock web 102 is reinforced by providing a plurality of single lock ribs 103 , so that after the single lock seat 100 is welded to the side beam 1 and the longitudinal beam 3 through the single lock web 102 , a more reliable fixing strength can be obtained.

[0055] The single-locking web 102 is a wedge-shaped structure, with its height gradually decreasing from the side beam 1 to the longitudinal beam 3. Since the side beam 1 is taller, the end of the single-locking web 102 connecting to the side beam 1 is designed to be larger. Since the longitudinal beam 3 is shorter, the end of the single-locking web 102 connecting to the longitudinal beam 3 is designed to be smaller.

[0056] The bottom of the single-lock web 102 is connected to the lower pad of the side sill 1. The bottom of the single-lock web 102 can be designed to have the same outer profile as the connection between the lower pad and the web of the side sill 1. During installation, the bottom of the single-lock web 102 can be pressed against the connection between the lower pad and the web of the side sill 1 to provide a larger contact area, and then the corresponding position can be welded.

[0057] Further, such as Figure 4 As shown, the side of the single lock base 100 closest to the end beam 5 of the vehicle underframe is connected to the end beam 5 via a connecting plate 2. The connecting plate 2 is a special-shaped plate, one end of which can be welded to the end beam 5, while the other end is suspended and does not need to be fixed. The end of the connecting plate 2 facing the single lock base 100 has a support notch, and the bottom edge of the support notch supports the single lock support plate 101. It should be noted that the connecting plate 2 can also be welded to the single lock web 102 to achieve a fixed connection to the single lock base 100.

[0058] In a specific embodiment of the present invention, Figure 2 and Figure 5 As shown, to improve the load-bearing capacity of the double lock base 200, the double lock base 200 may further include a double lock end support 205. The double lock end support 205 and the double lock rib plate 203 are respectively located outside the two ends of the second tilt avoidance hole 204. The double lock rib plate 203 is located at the first end of the second tilt avoidance hole 204, while the double lock end support 205 is disposed on the underside of the double lock support plate 201 and at the second end of the second tilt avoidance hole 204. The double lock end support 205 may also be connected to the web of the central crossbeam 4 of the vehicle body chassis. The double lock end support 205 may also be connected to the web of the central crossbeam 4 by welding.

[0059] The end of one end of the double-lock transverse rib 202 can be attached to the double-lock end support 205 and welded to the double-lock end support 205 to improve the strength of the double-lock base 200. The upper end of the double-lock end support 205 can be provided with an upper bend 2051, and the lower end can be provided with a lower bend 2052. In this embodiment, the upper bend 2051 and the lower bend 2052 on the double-lock end support 205 can improve the deformation resistance of the double-lock end support 205, thereby improving the load-bearing capacity of the double-lock base 200. The upper bend 2051 and the lower bend 2052 can both be bent away from the double-lock vertical rib 203 to avoid affecting the layout area of ​​the double-lock transverse rib 202. The upper bend 2051 can be attached to the lower surface of the double-lock support plate 201 and welded to the double-lock support plate 201. The double-lock vertical ribs 203, the double-lock supporting plates 201 and the double-lock transverse ribs 202 can be arranged vertically in pairs, and the angle relationship between the three can also be designed according to needs, and is not limited to being perpendicular to each other.

[0060] The double-lock end support 205 can be connected to a plurality of support ribs 206, one end of the support rib 206 can be connected to the upper bending portion 2051, and the other end can be connected to the lower bending portion 2052, and the connection can also be connected by welding. The number of support ribs 206 can be designed according to demand and is not limited to Figure 2 Two are shown.

[0061] The double-lock transverse rib 202 is a wedge-shaped structure. From close to the side beam 1 to away from the side beam 1, the height dimension of the double-lock transverse rib 202 gradually decreases. Since the height dimension of the side beam 1 is larger, the end of the double-lock transverse rib 202 connected to the side beam 1 is designed to be larger; since the other end of the double-lock transverse rib 202 does not need to be connected to the vehicle body frame, the end of the double-lock transverse rib 202 connected to the double-lock end support 205 can be designed to be smaller.

[0062] The bottom of the double-lock transverse rib 202 is connected to the lower pad of the side member 1. The bottom of the double-lock transverse rib 202 can be designed to have the same outer profile as the connection between the lower pad and the web of the side member 1. During installation, the bottom of the double-lock transverse rib 202 can be pressed against the connection between the lower pad and the web of the side member 1 to create a larger contact area, and then the corresponding position can be welded.

[0063] In a specific embodiment of the present invention, the single lock seat 100 and the double lock seat 200 are connected to the vehicle body chassis by welding. The plates of the single lock seat 100 and the double lock seat 200 are also connected by welding.

[0064] like Figure 6-Figure 9As shown, the container locking device 300 on the single lock base 100 is installed on the single lock support plate 101 at a position corresponding to the first tilt avoidance hole 104; the container locking device 300 on the double lock base 200 is installed on the double lock support plate 201 at a position corresponding to the second tilt avoidance hole 204. After the vehicle floor is laid on the vehicle chassis, the single lock base 100 and the double lock base 200 are both located below the vehicle floor. The distance from the bottom of the vehicle floor ensures that most or all of the locking support base 301 of the container locking device 300 is located below the vehicle floor, and only the lock head device 302 is located above the vehicle floor to ensure the flatness of the vehicle floor.

[0065] The container locking device 300 disclosed in this embodiment includes a locking support 301, a locking head device 302 and a shielding cover 303. The locking support 301 has a mounting slot, the locking head device 302 is hinged to the mounting slot and covers a portion of the mounting slot. The locking head device 302 can be switched between a use position and a hidden position. When the locking head device 302 is in the use position, the lock head of the locking head device 302 faces upward (such as Figure 8 As shown in FIG), when the locking device 302 is in the hidden position, the locking head of the locking device 302 faces downward (as shown in FIG). Figure 9 shown).

[0066] When the lock head of the locking device 302 is facing upward, the locking device 302 can extend out of the vehicle floor to position the four bottom corners of the container. When the lock head of the locking device 302 is facing downward, the locking device 302 can be turned over to the bottom of the vehicle floor to ensure the flatness of the vehicle floor.

[0067] Because the lock mechanism 302 requires a large turning space when flipping between the use and concealed positions, the mounting slot of the locking support 301 needs to be designed to be large to ensure that the lock mechanism 302 can complete the flipping action. However, after flipping, a portion of the mounting slot is exposed, so a shielding cover 303 is added to address this issue. The shielding cover 303 is hinged to the mounting slot and covers the remaining area of ​​the mounting slot, ensuring that no part of the mounting slot is exposed.

[0068] The shielding cover 303 is hinged to the locking support 301 via a hinge. The shielding cover 303 can be conveniently provided with an opening and closing hole to facilitate the insertion of a finger to pry the shielding cover 303 and rotate it. The shielding cover 303 can be hinged to the hinge hole of the locking support 301. When the locking device 302 is needed, the shielding cover 303 must first be opened to allow space for the locking device 302 to flip over.

[0069] If the locking device 302 can only rotate along a single axis, it will not be able to fit against one side wall of the mounting slot. Therefore, in this embodiment, a track groove is provided on the inner side wall of the mounting slot to cooperate with the rotating shaft of the locking device 302. The rotating shaft of the locking device 302 rotates within the track groove. After the rotation is completed, the rotating shaft of the locking device 302 slides within the track groove, so that the locking device 302 abuts against one side wall of the mounting slot, and then the shielding cover 303 is closed.
