Detailed Implementation

[0063] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0064] See Figures 1 to 12 As shown, this embodiment provides a two-stage balanced split-type chassis for transporting long and wide cargo, including: a first chassis 11 and a second chassis 12, which are arranged sequentially; a first large chassis 21, which is located at the bottom of the first chassis 11 and is connected to the first chassis 11 via a core plate device; and a second large chassis 22, which is located at the bottom of the first chassis 11 and the second chassis 12 and is connected to the first chassis 11 via a core plate device, and is also connected to the second chassis 12.

[0065] In this embodiment, since the first large chassis 21 is located at the bottom of the first frame 11 and the first large chassis 21 and the first frame 11 are connected by a core disk device, and the second large chassis 22 is located at the bottom of the first frame 11 and the second frame 12, the second large chassis 22 and the first frame 11 are connected by a core disk device, and the second large chassis 22 is connected to the second frame 12, it is equivalent to the first frame 11 and the second frame 12 being separated, and the frame is a split frame, which can meet the clearance requirements, and the first frame 11 and the second frame 12 can be carried out separately, which is beneficial to improving the stability of the frame load-bearing.

[0066] In this application, the chassis is a split chassis, with the first chassis and the second chassis not directly connected. When passing through small curves, the second chassis moves synchronously with the second large chassis, which improves the vehicle's performance on small curves, helps to meet clearance requirements, and the first chassis and the second chassis can bear loads separately, which helps to improve the stability of the chassis load.

[0067] It should be noted that, in this embodiment, the core disk device may include an upper core disk and a lower core disk 004. An upper core disk is disposed on the first frame 11, and a lower core disk 004 is disposed on the first main frame 21. The upper core disk on the first frame 11 and the lower core disk 004 on the first main frame 21 are connected, thereby connecting the first main frame 21 and the first frame 11. Alternatively, an upper core disk is disposed on the first frame 11, and a lower core disk 004 is disposed on the second main frame 22. The upper core disk on the first frame 11 and the lower core disk 004 on the second main frame 22 are connected, thereby connecting the second main frame 22 and the first frame 11.

[0068] It should be noted that, in this embodiment of the application, the first frame 11 and the first main chassis 21 can be connected by a core plate device and a side bearing device 005. That is, the first main chassis 21 is provided with a lower core plate 004 and a side bearing device 005, the first frame 11 is provided with an upper core plate, the upper core plate on the first frame 11 is connected to the lower core plate 004 on the first main chassis 21, and the first frame 11 is connected to the side bearing device 005, so that the first frame 11 is connected to the first main chassis 21.

[0069] In addition, in this embodiment, a lower core plate 004 and a connecting part 006 are provided on the second large chassis 22; the lower core plate 004 is connected to the upper core plate on the first frame 11; and the connecting part 006 is connected to the second frame 12. By providing the lower core plate 004 and the connecting part 006 on the second large chassis 22 and the upper core plate on the first frame 11, when the second large chassis 22 needs to be connected to the first frame 11, the upper core plate and the lower core plate 004 can be directly connected; and when the second frame 12 needs to be connected to the second large chassis 22, the connecting part 006 can be directly connected to the second frame 12, thereby facilitating the connection of the second large chassis 22 to the first frame 11 and the second frame 12 respectively.

[0070] Additionally, in some embodiments, such as Figure 7 and Figure 9 As shown, a lower core plate 004 and a connecting part 006 can be installed on the second large base frame 22; the lower core plate 004 and the connecting part 006 are arranged sequentially along the length direction of the second large base frame 22; the lower core plate 004 is connected to the upper core plate on the first frame 11; the connecting part 006 is connected to the second frame 12.

[0071] By providing a lower core plate 004 and a connecting part 006 on the second large chassis 22, when both the first frame 11 and the second frame 12 are connected to the second large chassis 22, the upper core plate on the first frame 11 and the lower core plate 004 on the second large chassis 22 are connected, and the second frame 12 is connected to the connecting part 006. The lower core plate 004 and the connecting part 006 are arranged sequentially along the length direction of the second large chassis 22. Thus, when both the first frame 11 and the second frame 12 are connected to the second large chassis 22, the first frame 11 and the second frame 12 will not interfere with each other, thereby facilitating the connection of both the first frame 11 and the second frame 12 to the second large chassis 22.

[0072] Additionally, in some embodiments, such as Figure 7 As shown, a connecting portion 006 is provided on each side of the second main frame 22 along its width direction; the second frame 12 has two second side beams 122 spaced apart; the two second side beams 122 are respectively connected to the corresponding connecting portions 006. That is, a connecting portion 006 is provided on each side of the second main frame 22 along its width direction, so that when the second frame 12 is connected to the second main frame 22, the two side beams of the second frame 12 can be connected to the two connecting portions 006 respectively in the width direction of the second main frame 22, making the connection between the second frame 12 and the second main frame 22 more secure.

[0073] Additionally, in some embodiments, such as Figure 5 As shown, the second side beam 122 has a slot 1221 and a socket 1222 that connects to the slot 1221; the connecting part 006 is inserted into the slot 1221; one end of the connector passes through the socket 1222 and the connecting part 006 to connect the connecting part 006 and the second side beam 122.

[0074] When it is necessary to connect the second side beam 122 to the second main frame 22, the connecting part 006 can be directly inserted into the slot 1221 on the second side beam 122. Then, the connector is passed through the insertion hole 1222 on the second side beam 122, and the connector part passes through the connecting part 006. Thus, the connector will fix the connecting part 006, connecting the connecting part 006 to the second side beam 122. In other words, this setting facilitates the connection between the connecting part 006 and the second side beam 122.

[0075] It should be noted that the connecting part 006 may be provided with a connecting hole, so that after the connecting part 006 is inserted into the slot 1221, one end of the connector can pass through the insertion hole 1222 and the connector passes through the connecting hole on the connector, so that the connecting part 006 is connected to the second side beam 122 through the connector.

[0076] Additionally, in some embodiments, such as Figure 5As shown, the second side beam 122 has a shell 1223 and a plurality of stiffening plates 1224 disposed inside the shell 1223; a slot 1221 is formed between two adjacent stiffening plates 1224; the shell 1223 is provided with a slot that connects to the slot 1221; the connecting part 006 is inserted into the slot 1221 through the slot; the shell 1223 and each stiffening plate 1224 are provided with a hole 1222; the connecting member is disposed through each hole 1222.

[0077] With this configuration, when connecting the second side beam 122 to the connecting part 006, the connecting part 006 can be directly inserted through the slot into the slot 1221 communicating with the slot. Then, the connector passes through the insertion hole 1222 on the outer shell 1223 and through the insertion hole 1222 on the stiffening plate 1224, allowing the connector to pass through the connecting part 006 and thus fix the connecting part 006, connecting the second side beam 122 to the connecting part 006. In other words, by providing multiple stiffening plates 1224 inside the outer shell 1223, it is easy to form the slot 1221. The slot on the outer shell 1223 facilitates the insertion of the connecting part 006 into the slot 1221. The insertion holes 1222 on the outer shell 1223 and the stiffening plate 1224 facilitate the connector passing through the outer shell 1223 and the stiffening plate 1224 to fix the connecting part 006. In addition, multiple stiffeners 1224 are provided in the outer shell 1223. The multiple stiffeners 1224 can also strengthen the outer shell 1223, thereby improving the strength of the outer shell 1223.

[0078] It should be noted that, in this embodiment, the plurality of stiffening plates 1224 in the outer shell 1223 can be equally spaced within the outer shell 1223, that is, the distance between any two adjacent stiffening plates 1224 is a fixed value. Of course, the plurality of stiffening plates 1224 may not be equally spaced. This embodiment does not limit this.

[0079] Additionally, in some embodiments, such as Figure 7 As shown, the second large base frame 22 includes a central base 2201 and a first segment 2202 and a second segment 2203 respectively disposed on both sides of the central base 2201; a lower core plate 004 is disposed on the central base 2201; a connecting part 006 is disposed on the central base 2201 and / or the second segment 2203; one end of the first segment 2202 opposite to the central base 2201 is used to connect to the track running device, and the second segment 2203 is fixedly connected to the second frame 12.

[0080] A connecting portion 006 can be provided on the middle seat 2201. In this case, one connecting portion 006 can be provided on each of the opposite sides of the middle seat 2201 along the width direction of the second frame 12. When the connecting portion 006 is provided on the second segment 2203, one connecting portion 006 can be provided on each of the opposite sides of the second segment 2203 along the width direction of the second frame 12. In addition, an upper core plate can be provided on the end of the first segment 2202 away from the middle seat 2201, and a lower core plate 004 can be provided on the track running device. The upper core plate and the lower core plate 004 are connected, so that the end of the first segment 2202 away from the middle seat 2201 is connected to the track running device.

[0081] It should be noted that in this embodiment, the middle seat 2201 can be concave, that is, the position of the middle seat 2201 is lower than the position of the first segment 2202 and the second segment 2203. Therefore, when the upper core plate on the first frame 11 and the lower core plate 004 on the middle seat 2201 are connected, the connection position between the first frame 11 and the middle seat 2201 is lower, which is beneficial to lowering the center of gravity of the split-type chassis of the secondary balance structure for transporting long and long goods, making the split-type chassis of the secondary balance structure for transporting long and long goods more stable, and also beneficial to reducing the height of the split-type chassis of the secondary balance structure for transporting long and long goods.

[0082] Additionally, in some embodiments, such as Figure 5 As shown, the second frame 12 has an end beam 123 and two second side beams 122; the end beam 123 is located at the end of the second side beams 122 and the end beam 123 is connected to the two second side beams 122 respectively; the end of the second frame 12 near the first frame 11 is connected to the connecting part 006, and the end beam 123 of the second frame 12 away from the first frame 11 is fixedly connected to the second segment 2203.

[0083] The second frame 12 near the first frame 11 may be provided with a slot 1221 and a socket 1222 that connects to the slot 1221. When the second frame 12 near the first frame 11 is connected to the connecting part 006, the connecting part 006 can be inserted into the slot 1221, and then the connecting piece passes through the socket 1222 and the connecting part 006 to connect the second frame 12 near the first frame 11 to the connecting part 006.

[0084] Additionally, in some embodiments, such as Figure 7 As shown, the second segment 2203 has a recessed step portion 22031 at one end away from the middle seat 2201; the end beam 123 is supported on the recessed step portion 22031; the end beam 123 and the recessed step portion 22031 are connected and fixed by fasteners.

[0085] Since the second segment 2203 has a recessed step 22031 at one end away from the middle seat 2201, when connecting the second frame 12 to the second segment 2203, the end beam 123 can be supported on the recessed step 22031. Then, the end beam 123 and the recessed step 22031 are connected and fixed by fasteners. Furthermore, the setting of the recessed step 22031 is equivalent to making the connection position between the second frame 12 and the second segment 2203 lower, which is conducive to lowering the center of gravity of the split-type underframe of the secondary balance structure for transporting long and long goods, making the split-type underframe of the secondary balance structure for transporting long and long goods more stable, and also conducive to reducing the height of the split-type underframe of the secondary balance structure for transporting long and long goods.

[0086] It should be noted that, in this embodiment, the fastener can be a bolt. In this case, a through hole can be provided on the end beam 123, and a threaded hole can be provided on the recessed step portion 22031. The bolt is passed through the through hole on the end beam 123 and then inserted into the threaded hole, thereby connecting and fixing the end beam 123 and the recessed step portion 22031. In addition, there can be multiple fasteners, which can make the connection between the end beam 123 and the recessed step portion 22031 more secure.

[0087] Of course, in this embodiment, the end beam 123 of the second frame 12 facing away from the first frame 11 and the second segment 2203 can be fixedly connected in other ways, such as welding the end beam 123 of the second frame 12 facing away from the first frame 11 and the second segment 2203. This embodiment does not limit the method of fixing the end beam 123 of the second frame 12 facing away from the first frame 11 and the second segment 2203.

[0088] Additionally, in some embodiments, such as Figure 7 As shown, the lower edges of the first segment 2202 and the second segment 2203 are both provided with end pillow beams 202; the end pillow beams 202 are used to connect the track running device.

[0089] By providing end pillow beams 202 at the lower edges of both the first segment 2202 and the second segment 2203, the end pillow beams 202 can be directly connected to the track running device when connecting the first segment 2202 and the second segment 2203 to the track running device, thus facilitating the connection of the first segment 2202 and the second segment 2203 to the track running device.

[0090] It should be noted that an upper core plate can be installed on the end bolster 202 of the lower edge of the first segment 2202, and a lower core plate 004 can be installed on the track running device. The upper core plate and the lower core plate 004 are connected, so that the end bolster 202 of the lower edge of the first segment 2202 is connected to the track running device. Similarly, an upper core plate can be installed on the end bolster 202 of the lower edge of the second segment 2203, and a lower core plate 004 can be installed on the track running device. The upper core plate and the lower core plate 004 are connected, so that the end bolster 202 of the lower edge of the second segment 2203 is connected to the track running device.

[0091] Additionally, in some embodiments, such as Figure 3 As shown, the first frame 11 may include two first side beams 112 spaced apart; the second frame 12 may include two second side beams 122 spaced apart; a first segment 2202 extends between the two first side beams 112 and is flush with the first side beams 112; a second segment 2203 extends between the two second side beams 122 and is flush with the second side beams 122.

[0092] Because the first segment 2202 extends between the two first side beams 112 and is flush with the first side beams 112, it does not protrude from the upper surface of the first side beams 112. Therefore, in the height direction of the secondary balanced structure split-type underframe for transporting long and long cargo, the first segment 2202 will not affect the height of the secondary balanced structure split-type underframe for transporting long and long cargo, thus avoiding the problem of increasing the height of the secondary balanced structure split-type underframe for transporting long and long cargo. Similarly, the second segment 2203 extends between the two second side beams 122 and is flush with the second side beams 122. Therefore, the second segment 2203 does not protrude from the upper surface of the second side beams 122. Thus, in the height direction of the secondary balanced structure split-type underframe for transporting long and long cargo, the second segment 2203 will not affect the height of the secondary balanced structure split-type underframe for transporting long and long cargo, thus avoiding the problem of increasing the height of the secondary balanced structure split-type underframe for transporting long and long cargo. This design avoids the problem of increased height in the secondary balanced structure of the split-type underframe for transporting long and heavy cargo, and helps to reduce the height of the secondary balanced structure of the split-type underframe for transporting long and heavy cargo.

[0093] Additionally, in some embodiments, such as Figure 8 As shown, the track-running device may include two shafts 51, with track-fitting wheels 52 connected to both ends of each shaft 51. This configuration makes the track-running device essentially a two-axis structure, resulting in greater structural stability. Furthermore, the track-fitting wheels 52 connecting both ends of the two shafts 51 facilitate movement of the track-running device on the track.

[0094] In practical applications, the track-fitting wheel 52 can be fitted with the track, so that once the track-fitting wheel 52 rotates, the track-fitting wheel 52 can move on the track, thereby moving the track-traveling device.

[0095] Additionally, in some embodiments, such as Figure 8 As shown, a braking device 53 can also be installed on the track running device. The braking device 53 is located on the lower side of the track running device, so that after the track running device moves to a suitable position, the track running device can be braked by the braking device 53, thereby facilitating the stopping of the track running device.

[0096] In some embodiments, the second segment 2203 is longer than the first segment 2202. This arrangement makes the second underframe 22 an asymmetrical structure, which is beneficial for the connection between the second segment 2203 and the end beam 123 of the second frame 12.

[0097] Additionally, in some embodiments, such as Figure 8 As shown, the track running device has a recessed portion 501; the end of the first segment 2202 opposite to the middle seat 2201 is connected to the recessed portion 501 by a core disk device.

[0098] Because the track running device has a recessed portion 501, when the end of the first segment 2202 away from the middle seat 2201 is connected to the track running device, the end of the first segment 2202 away from the middle seat 2201 can be connected to the recessed portion 501 on the track running device. That is, the end of the first segment 2202 away from the middle seat 2201 is connected to the recessed portion 501 through the core plate device. This makes the connection position of the end of the first segment 2202 away from the middle seat 2201 lower, which is beneficial to lowering the center of gravity of the split-type underframe of the secondary balance structure for transporting long and long goods. This makes the split-type underframe of the secondary balance structure for transporting long and long goods more stable and also helps to reduce the height of the split-type underframe of the secondary balance structure for transporting long and long goods.

[0099] It should be noted that the track traveling device can have multiple recesses 501. Recesses 501 can be set wherever the track traveling device needs to connect with the small base frame. Additionally, the core plate device can include an upper core plate and a lower core plate 004. The lower core plate 004 can be located at the bottom of the recess 501, and the upper core plate can be located on the small base frame. The upper core plate and the lower core plate 004 are connected, thereby connecting the small base frame with the recess 501.

[0100] Additionally, in some embodiments, such as Figure 1As shown, the two-stage balanced structure split-type underframe for transporting long and heavy cargo may also include a tail support device 70, which is connected to the second frame 12 and supported on the rails or railway transshipment device.

[0101] By setting a position support device and connecting the tail support device 70 to the second frame 12, when a simply supported beam is placed on the second frame 12, the portion of the simply supported beam protruding from the second frame 12 can be supported by the tail support device 70. The tail support device 70 is supported by the rail or railway transport frame device, which is equivalent to the tail support device 70 being supported. This allows the tail support device 70 to support the simply supported beam, which is beneficial for the two-stage balanced structure split underframe transport of simply supported beams for transporting long and long goods.

[0102] It should be noted that the tail support device 70 may include a load-bearing part and a support part. The load-bearing part is connected to the second frame 12, and the support part is connected to the load-bearing part. When using the two-stage balanced split-type underframe for transporting long and heavy goods, the support part is supported on the rails or railway transfer frame device.

[0103] It should be noted that, in this embodiment, the rear support device 70 can be connected to the end of the second frame 12 via fasteners, thereby fixing the rear support device 70 relative to the second frame 12. The fasteners can be bolts, pins, etc. Alternatively, the rear support device 70 can also be connected to the end of the second frame 12 via a hinge, allowing the rear support device 70 to move relative to the second frame 12. This embodiment does not limit the scope of this application.

[0104] In addition, in some embodiments, the two-stage balanced split-type chassis for transporting long and heavy cargo may also include a first moving platform and a second moving platform; a first track is provided on the first frame 11, a second track is provided on the second frame 12, the first moving platform is connected to the first track, and the second moving platform is connected to the second track.

[0105] When the first moving platform is connected to the first track, it can slide along the track, allowing its position to change. Similarly, when the second moving platform is connected to the second track, it can slide along the track, also allowing its position to change. This arrangement allows items to be transported by moving the first and / or second moving platforms after they have been placed on them. In other words, by setting up the first and second moving platforms, with the first track on the first frame 11 and the second track on the second frame 12, it is convenient to transport items using the first and / or second moving platforms. For example, when a simply supported beam is placed on the first and / or second moving platforms, the beam can be moved by moving the first and / or second moving platforms.

[0106] In some embodiments, the width of the first frame 11 gradually increases from the middle to both ends. This arrangement allows the first frame 11 to meet railway clearance requirements and increases its strength and load-bearing capacity.

[0107] It should be noted that when the width of the first frame 11 increases along the direction from the middle to both ends of the first frame 11, the width of the first frame 11 can increase uniformly, with the width increasing in a linear relationship. Of course, the width of the first frame 11 can also increase non-uniformly, with the width increasing in a non-linear relationship. In this embodiment, the present application does not limit this.

[0108] Additionally, in some embodiments, such as Figure 3 and Figure 4 As shown, the first frame 11 may include two first side beams 112 spaced apart and connected to each other; the first side beam 112 includes: a main beam 1121; an upper reinforcing beam 1122 connected to the top of the main beam 1121; and a lower reinforcing beam 1123 connected to the bottom of the main beam 1121.

[0109] By setting an upper reinforcing beam 1122 at the top of the main beam 1121, the strength of the top of the main beam 1121 is increased. By setting a lower reinforcing beam 1123 at the bottom of the main beam 1121, the strength of the bottom of the main beam 1121 is increased. In other words, the strength of both the top and bottom of the main beam 1121 is increased, thereby increasing the overall strength of the main beam 1121 and improving its load-bearing capacity.

[0110] It should be noted that the length of the upper reinforcing beam 1122 can be equal to the length of the main beam 1121. In this case, one end of the upper reinforcing beam 1122 is flush with one end of the main beam 1121, and the other end of the upper reinforcing cavity is flush with the other end of the main beam 1121. Of course, the length of the upper reinforcing beam 1122 can also be less than the length of the main beam 1121, so that the upper reinforcing cavity is located between the two ends of the main beam 1121.

[0111] In addition, in this embodiment, the upper reinforcing beam 1122 can be welded to the top of the main beam 1121, and the lower reinforcing beam 1123 can also be welded to the bottom of the main beam 1121. Alternatively, the upper reinforcing beam 1122 can also be connected to the top of the main beam 1121 using fasteners, for example, by bolts or by pins. Similarly, the lower reinforcing beam 1123 can also be connected to the bottom of the main beam 1121 using fasteners, for example, by bolts or by pins. This embodiment does not limit the specific details of this embodiment.

[0112] In addition, in this embodiment of the application, the first frame 11 also includes a middle connecting beam 113 and an end connecting beam 114. The middle connecting beam 113 is connected to the middle part of the first side beam 112, and the end connecting beam 114 is connected to the end of the first side beam 112. The two first side beams 112 are connected by the middle connecting beam 113 and the end connecting beam 114.

[0113] Additionally, in some embodiments, such as Figure 4 As shown, the lower reinforcing beam 1123 may include an end reinforcing beam 11231 and a middle reinforcing beam 11232; the end reinforcing beam 11231 is disposed at both ends of the main beam 1121, and the middle reinforcing beam 11232 is disposed in the middle of the main beam 1121.

[0114] When the end reinforcing beams 11231 are installed at both ends of the main beam 1121, the strength at both ends of the main beam 1121 is increased by the end reinforcing beams 11231. Meanwhile, the middle reinforcing beams 11232 are installed in the middle of the main beam 1121, increasing the strength of the middle section of the main beam 1121. This effectively increases the strength of the main beam 1121 at both ends and in the middle along its extension direction, resulting in a better strength increase and a more balanced increase in the overall strength of the main beam 1121.

[0115] In this embodiment, since the first large chassis 21 is located at the bottom of the first frame 11 and the first large chassis 21 and the first frame 11 are connected by a core disk device, and the second large chassis 22 is located at the bottom of the first frame 11 and the second frame 12, the second large chassis 22 and the first frame 11 are connected by a core disk device, and the second large chassis 22 is connected to the second frame 12, it is equivalent to the first frame 11 and the second frame 12 being separated, and the frame is a split frame, which can meet the clearance requirements, and the first frame 11 and the second frame 12 can be carried out separately, which is beneficial to improving the stability of the frame load-bearing.
