[0089] The core of the present invention is to provide a railway multifunctional flat car to meet the transportation needs of prefabricated beams of various specifications.

[0090] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0091] like Figure 1-Figure 4 As shown, the railway multifunctional flat car disclosed in the embodiment of the present invention includes a chassis assembly 200, a chassis floor 230 and a prefabricated beam transport support device 100. The chassis floor 230 is laid on the chassis assembly 200, and the chassis floor 230 can be fixed on the chassis assembly 200 by fasteners.

[0092] At least three spaced-apart mounting portions are provided along the length direction of the chassis floor 230 . The mounting portions may be composed of a plurality of fastener holes, and the precast beam transport support device 100 is fixed to the fastener holes of the mounting portions by fasteners.

[0093] The precast beam transport support device 100 is fixed to a corresponding installation portion according to the length of the precast beam 400 to be transported, that is, the precast beam transport support device 100 is fixed to different installation portions and can support precast beams 400 of different specifications.

[0094] The railway multifunctional flat car provided by the present invention is provided with at least three installation parts arranged at intervals along the length direction of the chassis floor 230, and the installation parts are used to fix the precast beam transport support device 100. The precast beam transport support device 100 is fixed on different installation parts to support precast beams of different specifications. When it is necessary to transport a 32m precast beam, three railway multifunctional flat cars can be used for transportation. For example, the precast beam transport support device 100 can be fixed on two railway multifunctional flat cars located at the end to support the 32m precast beam; when it is necessary to transport a 24m precast beam, two railway multifunctional flat cars can be used for transportation. For example, the precast beam transport support device 100 can be fixed on two railway multifunctional flat cars to support the 24m precast beam. The present invention can match the transportation of precast beams of various specifications according to the different fixed positions of the precast beam transport support device 100, thereby improving the use efficiency.

[0095] For ease of understanding, in this embodiment, three mounting parts are provided on the chassis floor 230 as an example for description. One of the mounting parts is located in the middle position in the length direction of the chassis floor 230, and the other two mounting parts are symmetrically arranged along the middle mounting part. The mounting part located in the middle is defined as the first mounting part, and the other two mounting parts are defined as the second mounting part and the third mounting part respectively. Along the travel direction of the railway multifunctional flat car, the mounting part located in front of the first mounting part is the second mounting part, and the mounting part located behind the first mounting part is the third mounting part.

[0096] When the length specification of the prefabricated beam 400 requires two multi-purpose railway flat cars for transportation, the prefabricated beam 400 is defined as a prefabricated beam of the first specification; when the length specification of the prefabricated beam 400 requires three multi-purpose railway flat cars for transportation, the prefabricated beam 400 is defined as a prefabricated beam of the second specification.

[0097] like Figure 6 As shown, when the precast beam 400 is a precast beam of the first specification, a precast beam of the first specification is transported by two railway multifunctional flat cars, and the precast beam transport support devices 100 on the two railway multifunctional flat cars are respectively installed on the second installation part and the third installation part, so that the distance between the precast beam transport support devices 100 on the two railway multifunctional flat cars is the farthest. Along the travel direction, the precast beam transport support device 100 on the railway multifunctional flat car located in the front is fixed on the second installation part, and the precast beam transport support device 100 on the railway multifunctional flat car located in the rear is fixed on the third installation part. With this fixing method, the distance between the two precast beam transport support devices 100 on the two railway multifunctional flat cars can be the farthest, so as to match the transportation of the precast beam of the first specification. In this embodiment, the precast beam of the first specification can be a 24m precast beam.

[0098] It should be noted that when a prefabricated beam 400 is transported by two railway multifunctional flat cars, the prefabricated beam transport support device 100 on the front railway multifunctional flat car can be fixed on the third mounting portion along the travel direction, and the prefabricated beam transport support device 100 on the rear railway multifunctional flat car can be fixed on the second mounting portion. By adopting this fixing method, the distance between the two prefabricated beam transport support devices 100 on the two railway multifunctional flat cars can be the shortest to match the first specification prefabricated beams with shorter transport lengths. The prefabricated beam transport support devices 100 can also be fixed on the first mounting portion. By adopting this fixing method, the distance between the two prefabricated beam transport support devices 100 on the two railway multifunctional flat cars can be medium to match the first specification prefabricated beams with medium transport lengths. Those skilled in the art can select the fixed positions of the prefabricated beam transport support devices 100 on the two railway multifunctional flat cars according to the specifications of the prefabricated beams 400.

[0099] like Figure 5When the precast beam 400 is a second-specification precast beam (such as a 32m precast beam), one second-specification precast beam needs to be transported by three multifunctional railway flat cars, and the middle multifunctional railway flat car among the three multifunctional railway flat cars is a traveling car, and the precast beam transport support devices 100 on the multifunctional railway flat cars at both ends are installed on the first installation part. The length of the second-specification precast beam is greater than the length of the first-specification precast beam.

[0100] It should be noted that when three railway multifunctional flat cars are needed for transportation, the precast beam transport support device 100 can also be fixed at other positions. For example, along the travel direction, the precast beam transport support device 100 on the front railway multifunctional flat car is fixed on the second mounting portion, and the precast beam transport support device 100 on the rear railway multifunctional flat car is fixed on the third mounting portion. With this fixing method, the distance between the two precast beam transport support devices 100 on the three railway multifunctional flat cars can be the farthest, so as to match the transportation of the longer second specification precast beams.

[0101] When a prefabricated beam 400 is transported by three railway multi-purpose flat cars, the prefabricated beam transport support device 100 on the front railway multi-purpose flat car can be fixed on the third mounting part along the driving direction, and the prefabricated beam transport support device 100 on the rear railway multi-purpose flat car can be fixed on the second mounting part. By adopting this fixing method, the distance between the two prefabricated beam transport support devices 100 on the three railway multi-purpose flat cars can be as short as possible to match the transportation of the shorter prefabricated beams of the second specification.

[0102] When the prefabricated beam transport support device 100 is installed to the second installation part or the third installation part, there is an unbalanced load because the second installation part and the third installation part deviate from the middle position of the railway multi-purpose flat car. In order to overcome the unbalanced load problem, a counterweight device 300 for preventing unbalanced load can be further provided on the chassis floor 230 to balance the weight of the railway multi-purpose flat car.

[0103] like Figure 7 As shown, the counterweight device 300 may include a bottom frame 301 and a counterweight body. The bottom frame 301 is fixed on the chassis floor 230 and has a plurality of accommodating spaces 302, and the counterweight body is arranged in the accommodating spaces 302. The counterweight device 300 can adjust the overall weight of the counterweight device 300 by adjusting the number of counterweight bodies according to the required working conditions, so as to ensure that the railway multi-purpose flat car will not be overloaded when transporting prefabricated beams 400 of different specifications.

[0104] In addition, a stopper 305 and / or a lifting lug 304 may be provided on the bottom frame 301. When in use, the stopper 305 is used to limit the position in the horizontal direction; when the counterweight device 300 is not in use, the lifting lug 304 may be used to lift the counterweight device 300 and place it elsewhere. The counterweight device 300 may be fixed by the container locking device 250 provided on the bottom frame device assembly 200. Specifically, a positioning hole 303 may be provided on the bottom frame 301, and the lock head of the container locking device 250 may be passed through the positioning hole 303 to fix the counterweight device 300.

[0105] like Figure 2 and Figure 3 As shown, the underframe assembly 200 includes a center beam 205, a side beam 201, a central cross beam 204 and an end beam 202. The side beams 201 are arranged in parallel with the center beam 205, and there are two of them, which are symmetrically arranged on both sides of the center beam 205. The side beams 201 and the center beam 205 can be H-shaped steel cut into a fish belly structure.

[0106] There are two central cross beams 204, and they are arranged symmetrically along the middle beam 205, that is, the central cross beams 204 need to be set on both the left and right sides of the middle beam 205. The central cross beams 204 are connected to the middle beam 205 and the side beams 201 respectively, and the central cross beams 204 are arranged in the middle of the length direction of the middle beam 205. There are two end beams 202, which are located at the two ends of the chassis assembly 200. They are arranged at the two ends of the middle beam 205 respectively, and the two ends of the end beams 202 are connected to the two side beams 201 respectively, that is, the end beams 202 need to be connected and fixed to both the two side beams 201 and the middle beam 205.

[0107] In order to improve the strength of the chassis assembly 200, the chassis assembly 200 may further include at least one of a bolster 206, a reinforcement beam 207, and an auxiliary beam 208. The bolster 206 is connected between the center beam 205 and the side beam 201; the reinforcement beam 207 is connected between the center beam 205 and the side beam 201, and is located between the bolster 206 and the central cross beam 204. The reinforcement beam 207 can be used to stabilize the precast beam transport support device 100. Since the reinforcement beam 207 is arranged in or near the installation area of ​​the precast beam transport support device 100, the installation stability of the precast beam transport support device 100 can be improved by arranging the reinforcement beam 207 in this area.

[0108] The auxiliary beam 208 is connected between the center beam 205 and the side beam 201 , and the auxiliary beam 208 may be arranged between the bolster beam 206 and the reinforcement beam 207 , and between the reinforcement beam 207 and the central cross beam 204 , so as to increase the strength of the region.

[0109] In this embodiment, each beam of the chassis assembly 200 can be made of high-strength weathering steel to ensure sufficient strength. Each beam can be welded together, and the auxiliary beam 208 is mainly composed of angle steel and cold-bent channel steel. A chassis floor 230 is provided on the upper part of the chassis assembly 200 for carrying goods in flat car conditions. The chassis floor 230 is composed of a door stop assembly 240 (both ends of the chassis floor 230 have a door stop assembly 240), an end floor, a middle floor, etc. The plane on the middle floor should be kept flush with the plane on the upper cover plate of the middle beam 205. By setting the door stop assembly 240, it can act as a door stop in container transportation conditions, and can also be used for small transport vehicles to pass through.

[0110] like Figure 2-Figure 4 As shown, in a specific embodiment of the present invention, the railway multifunctional flat car may further include a locking mounting seat for fixing a container locking device 250 (the container locking device 250 may be an F-TR type flip lock. When transporting containers, the container locking device 250 is adjusted to the working position. When transporting containers, the container locking device 250 is adjusted to the non-working position. The upper plane of the container locking device 250 in the non-working position is flush with the upper plane of the chassis floor 230 to ensure the assembly of the prefabricated beam transport support device 100 when transporting prefabricated beams). The locking mounting seat includes a single locking seat 210 and a double locking seat 220. The single locking seat 210 is used to install one container locking device 250, and the double locking seat 220 is used to install two container locking devices 250.

[0111] The single lock seat 210 is installed at the four corners of the chassis assembly 200, and the double lock seat 220 is installed on the central beam 204. The chassis floor 230 is provided with a single lock seat hole 231 at a position corresponding to the single lock seat 210, and a double lock seat hole 232 at a position corresponding to the double lock seat 220.

[0112] In this embodiment, the container locking device 250 can be fixed by the locking mounting seat, so that the railway multifunctional flat car can be used for container transportation. After the peak period of prefabricated beam transportation, the prefabricated beam transportation support device 100 can be removed from the chassis floor 230, and the railway multifunctional flat car can be used to transport containers.

[0113] like Fig.19 and Fig. 20As shown, a railway multifunctional flat car can simultaneously load two 20ft containers and one 40ft container. When two 20ft containers are simultaneously loaded on a railway multifunctional flat car, one end of one of the 20ft containers is fixed by the container locking devices 250 on the two single lock seats 210 at the first end of the chassis assembly 200 and the container locking devices 250 on the two middle double lock seats 220 near the first end; one end of the other 20ft container is fixed by the container locking devices 250 on the two single lock seats 210 at the second end of the chassis assembly 200 and the container locking devices 250 on the two middle double lock seats 220 near the second end. The 40ft container is fixed by the container locking devices 250 on the single lock seats 210 at the four end corners of the chassis assembly 200.

[0114] like Fig.19 and Fig.21 As shown, the single lock seat 210 includes a single lock support plate 211 and a single lock belly plate 212 arranged on the lower side of the single lock support plate 211. The position where the single lock support plate 211 is installed with the container locking device 250 is provided with a first flip avoidance hole 214, that is, the single lock support plate 211 only needs to install one container locking device 250, and therefore only needs to open one first flip avoidance hole 214.

[0115] One end of the single lock seat 210 is connected to the web of the side beam 201 of the chassis assembly 200 through the single lock web 212, and the other end is connected to the vertical surface of the longitudinal beam 203 of the chassis assembly 200, and the single lock support plate 211 is located under the upper pad of the side beam 201. Specifically, the end surface of the single lock web 212 can be welded to the web of the side beam 201, and the end surface of the single lock support plate 211 and the end surface of the single lock web 212 can be on the same plane. When welding, the single lock support plate 211 and the single lock web 212 can be welded together to the web of the side beam 201. The other end of the single lock web 212 can also be connected to the vertical surface of the longitudinal beam 203 by welding. If the other end of the single lock web 212 and the corresponding end of the single lock support plate 211 are also on the same plane, when welding, the single lock support plate 211 and the single lock web 212 can also be welded together to the vertical surface of the longitudinal beam 203.

[0116] like Fig. 20 and Fig. 22As shown, the double lock seat 220 includes a double lock support plate 221 and a double lock transverse rib plate 222 disposed in the middle of the lower side of the double lock support plate 221, and double lock vertical rib plates 223 connected to both sides of the double lock transverse rib plate 222. A second flip avoidance hole 224 is provided at the position where the double lock support plate 221 is installed with the container locking device 250. That is, the double lock support plate 221 is provided with two second flip avoidance holes 224, and the two second flip avoidance holes 224 are symmetrically arranged along the double lock transverse rib plate 222, and the two double lock vertical rib plates 223 can also be symmetrically arranged along the double lock transverse rib plate 222. It should be noted that the double lock vertical rib plate 223 should avoid the second flip avoidance hole 224. The double lock vertical rib plate 223 can be arranged vertically with the double lock transverse rib plate 222 and the double lock support plate 221, respectively. Of course, the angle between the three can also be designed according to the needs, and is not limited to vertical.

[0117] The double-lock transverse rib plate 222 is connected to the web of the side beam 201, the double-lock vertical rib plate 223 is connected to the web 2041 of the central cross beam 204 of the chassis assembly 200, and the double-lock support plate 221 is located under the upper pad of the central cross beam 204. Specifically, the double-lock transverse rib plate 222 can be connected to the web of the side beam 201 by welding. If the end surface of the double-lock support plate 221 and the end surface of the double-lock transverse rib plate 222 can be on the same plane, the double-lock support plate 221 and the double-lock transverse rib plate 222 can be welded together to the web of the side beam 201 during welding. The double-lock vertical rib plate 223 can also be connected to the web of the central cross beam 204 by welding.

[0118] In this embodiment, the single lock seat 210 is connected to the web of the side beam 201 of the chassis assembly 200 through its single lock web 212, and the other end of the single lock web 212 is connected to the vertical surface of the longitudinal beam 203 of the chassis assembly 200. The single lock seat 210 does not require the single lock support plate 211 to be supported on the pad of the cross beam, but the single lock web 212 is connected with the web of the side beam 201 and the vertical surface of the longitudinal beam 203 to fix the single lock seat 210, so that the single lock support plate 211 is located under the upper pad of the side beam 201, and then under the chassis floor 230.

[0119] The double lock seat 220 is connected to the web of the side beam 201 through the double lock transverse rib plate 222, and is connected to the web 2041 of the central cross beam 204 through the double lock vertical rib plate 223. The double lock seat 220 does not require the double lock support plate 221 to be supported on the pad of the cross beam, but uses the connection between the double lock transverse rib plate 222 and the web of the side beam 201, and the connection between the double lock vertical rib plate 223 and the web 2041 of the central cross beam 204 to achieve the fixation of the double lock seat 220, so that the double lock support plate 221 is located under the upper pads of the side beam 201 and the central cross beam 204, and then under the chassis floor 230.

[0120] In this embodiment, the single lock seat 210 and the double lock seat 220 are both installed below the plane of the chassis floor 230, so as to ensure that the upper plane of the container locking device 250 will not be higher than the upper plane of the chassis floor 230 after installation, meeting the requirement of reducing the height of the bearing surface. The single lock seat 210 and the double lock seat 220 of the present invention do not need to change the structural design of the chassis crossbeam, and can be independently assembled at a position that meets the conditions, with a reliable structure and convenient assembly.

[0121] In this embodiment, in order to improve the support strength and bearing capacity of the single lock seat 210, the single lock seat 210 may further include a single lock rib plate 213, two single lock web plates 212, and they are respectively located on both sides of the first flip avoidance hole 214, and the single lock rib plate 213 is connected between the two single lock web plates 212. In this embodiment, by connecting the single lock rib plate 213 between the two single lock web plates 212, the stability of the two single lock web plates 212 can be improved. Further, a plurality of single lock rib plates 213 may be provided, that is, at least two, and single lock rib plates 213 are provided at both ends of the first flip avoidance hole 214. Taking the case where there are two single lock rib plates 213 as an example, one single lock rib plate 213 is provided on the outer side of one end of the first flip avoidance hole 214, and the other single lock rib plate 213 is provided on the outer side of the other end of the first flip avoidance hole 214. In this embodiment, the single lock web 212 is reinforced by providing a plurality of single lock ribs 213 , so that after the single lock seat 210 is welded to the side beam 201 and the longitudinal beam 203 through the single lock web 212 , a more reliable fixing strength can be obtained.

[0122] The single locking web 212 is a wedge-shaped structure, and the height dimension of the single locking web 212 gradually decreases from the side beam 201 to the longitudinal beam 203. Since the height dimension of the side beam 201 is larger, the end of the single locking web 212 connected to the side beam 201 is designed to have a larger dimension; and the height dimension of the longitudinal beam 203 is smaller, so the end of the single locking web 212 connected to the longitudinal beam 203 is designed to have a smaller dimension.

[0123] The bottom of the single-lock web 212 is connected to the lower pad of the side beam 201, and the bottom of the single-lock web 212 can be designed to have the same outer contour as the connection between the lower pad and the web of the side beam 201. During installation, the bottom of the single-lock web 212 can be pressed against the connection between the lower pad and the web of the side beam 201 to have a larger contact area, and then the corresponding position can be welded.

[0124] Further, such as Fig.21As shown, the side of the single lock seat 210 close to the end beam 202 of the chassis device assembly 200 is connected to the end beam 202 through a connecting plate 209. The connecting plate 209 is a special-shaped plate, one end of which can be welded to the end beam 202, and the other end is suspended and does not need to be fixed. The end of the connecting plate 209 facing the single lock seat 210 has a support notch, and the single lock support plate 211 is supported by the lower edge of the support notch. It should be noted that the connecting plate 209 can also be welded to the single lock web 212 to achieve fixation with the single lock seat 210.

[0125] In a specific embodiment of the present invention, Fig. 20 and Fig. 22 As shown, in order to improve the bearing capacity of the double lock seat 220, the double lock seat 220 may further include a double lock end support 225, and the double lock end support 225 and the double lock rib plate 223 are respectively located at the outer sides of the two ends of the second flip avoidance hole 224. Among them, the double lock rib plate 223 is located at the first end of the second flip avoidance hole 224, and the double lock end support 225 is arranged on the lower side of the double lock support plate 221 and is located at the second end of the second flip avoidance hole 224. The double lock end support 225 may also be connected to the web 2041 of the central cross beam 204. The double lock end support 225 may also be connected to the web 2041 of the central cross beam 204 by welding.

[0126] The end of one end of the double lock transverse rib plate 222 can be attached to the double lock end support 225 and welded and fixed to the double lock end support 225 to improve the strength of the double lock seat 220. The upper end of the double lock end support 225 can be provided with an upper bending portion 2251, and the lower end can be provided with a lower bending portion 2252. In this embodiment, the upper bending portion 2251 and the lower bending portion 2252 are provided on the double lock end support 225 to improve the anti-deformation ability of the double lock end support 225, thereby improving the bearing capacity of the double lock seat 220. The upper bending portion 2251 and the lower bending portion 2252 can be bent to a side away from the double lock vertical rib plate 223 to avoid affecting the layout area of ​​the double lock transverse rib plate 222. The upper bending portion 2251 can be attached to the lower surface of the double lock support plate 221 and welded and fixed to the double lock support plate 221. The double-lock vertical rib plates 223, the double-lock supporting plates 221 and the double-lock transverse rib plates 222 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.

[0127] The double-lock end support 225 may be connected to a plurality of support ribs 226, one end of the support rib 226 may be connected to the upper bending portion 2251, and the other end may be connected to the lower bending portion 2252, and the connection may also be connected by welding. The number of support ribs 226 may be designed according to the needs and is not limited to Figure 2 Two are shown.

[0128] The double-lock transverse rib plate 222 is a wedge-shaped structure. The height dimension of the double-lock transverse rib plate 222 gradually decreases from the direction close to the side beam 201 to the direction away from the side beam 201. Since the height dimension of the side beam 201 is larger, the end of the double-lock transverse rib plate 222 connected to the side beam 201 is designed to have a larger dimension; since the other end of the double-lock transverse rib plate 222 does not need to be connected to the chassis device assembly 200, the end of the double-lock transverse rib plate 222 connected to the double-lock end support 225 can be designed to have a smaller dimension.

[0129] The bottom of the double-lock transverse rib plate 222 is connected to the lower pad of the side beam 201, and the bottom of the double-lock transverse rib plate 222 can be designed to have the same outer contour as the connection between the lower pad and the web of the side beam 201. During installation, the bottom of the double-lock transverse rib plate 222 can be pressed against the connection between the lower pad and the web of the side beam 201 to have a larger contact area, and then the corresponding position can be welded.

[0130] In a specific embodiment of the present invention, the single lock seat 210 and the double lock seat 220 are connected to the chassis assembly 200 by welding. The plates of the single lock seat 210 and the double lock seat 220 are also connected by welding.

[0131] The container locking device 250 on the single lock seat 210 is installed on the single lock support plate 211 at a position corresponding to the first rollover avoidance hole 214; the container locking device 250 on the double lock seat 220 is installed on the double lock support plate 221 at a position corresponding to the second rollover avoidance hole 224. After the chassis floor 230 is laid on the chassis device assembly 200, the single lock seat 210 and the double lock seat 220 are both located below the chassis floor 230, and the distance from the bottom of the chassis floor 230 can ensure that most or all of the locking support seat of the container locking device 250 is located below the chassis floor 230, and only the lock head device is located above the chassis floor 230 to ensure the flatness of the chassis floor 230.

[0132] When the lock head of the container locking device 250 is facing upward (i.e., in the working position), the lock head can extend out of the chassis floor 230 to position the four bottom corners of the container. The lock head can be rotated downward (non-working position) so that the lock head is flipped under the chassis floor 230 to ensure the flatness of the chassis floor 230. The present invention adds a container transportation function on the basis of the prefabricated beam transportation function, greatly increases the frequency of vehicle transportation, and greatly improves the economic benefits.

[0133] Since the precast beam needs two precast beam transport support devices 100 to support it during transportation, in this embodiment, the two precast beam transport support devices 100 form a precast beam transport support device group, and the two precast beam transport support devices 100 of the precast beam transport support device group are respectively used to support the two ends of the precast beam 400. It should be noted that supporting the two ends of the precast beam 400 does not only refer to the ends of the precast beam 400, but as long as the supporting position of the precast beam transport support device 100 is located outside the middle of the precast beam 400, it is sufficient.

[0134] like Figure 5 and Figure 6 As shown, for ease of understanding, the two precast beam transport support devices 100 of the precast beam transport support device group are defined as a first precast beam transport support device 100a and a second precast beam transport support device 100b. The structures of the first precast beam transport support device 100a and the second precast beam transport support device 100b are basically the same. Since the structures of the two are basically the same, the same parts of the two are introduced uniformly and no longer introduced separately.

[0135] like Figure 8-Figure 11 and Fig.15 As shown, the first precast beam transport support device 100a and the second precast beam transport support device 100b disclosed in the embodiment of the present invention both include a steering wheel base 110, a steering wheel 120 and a brace device 130. According to the length specification of the precast beam 400, the steering wheel base 110 is mounted on a corresponding mounting portion. The fixing method of the steering wheel base 110 and the chassis floor 230 is not limited, which is related to the structural form of the mounting portion. For example, when the mounting portion is a fastening hole, the steering wheel base 110 can be assembled by fastening with fasteners.

[0136] The steering wheel base 110 has a first rotating part, and the steering wheel 120 has a second rotating part that is rotatably matched with the first rotating part, so that the steering wheel 120 is rotatably arranged on the steering wheel base 110. The steering wheel 120 has a prefabricated beam bearing area 124. When in use, the prefabricated beam is supported on the prefabricated beam bearing area 124. During transportation, when there is a vehicle turning scene, the steering wheel 120 will rotate relative to the steering wheel base 110 through the relative rotation of the first rotating part and the second rotating part according to the deflection requirement of the prefabricated beam 400.

[0137] The difference between the first precast beam transport support device 100a and the second precast beam transport support device 100b is that the structure of the first rotating part is different. The first rotating part of the first precast beam transport support device 100a is a sliding groove 114 (such as Fig.12 and Fig.13As shown in FIG. 1 , the sliding groove 114 extends along a first direction, which is the length direction of the railway multifunctional flat car. The two sets of support rod devices 130 are arranged on both sides of the prefabricated beam bearing area 124 along a second direction, and the first direction is perpendicular to the second direction.

[0138] The first rotating portion of the second precast beam transport support device 100b is a turning hole 117 (such as Fig.14 As shown in FIG. 1 ), the second rotating parts of the first precast beam transport support device 100a and the second precast beam transport support device 100b may both be steering shafts 125 (such as Fig.16 as shown).

[0139] The steering shaft 125 of the first precast beam transport support device 100a extends into the sliding groove 114. Since the part of the steering wheel base 110 that cooperates with the steering shaft 125 is the sliding groove 114, the steering shaft 125 can not only rotate relative to the sliding groove 114, but also move along the sliding groove 114. In this way, the steering wheel 120 can not only rotate relative to the steering wheel base 110, but also move relative to the steering wheel base 110 in the first direction, that is, move along the length direction of the vehicle body.

[0140] The steering shaft 125 of the second precast beam transport support device 100 b is rotationally matched with the steering hole 117 . Since the steering shaft 125 is rotationally matched with the steering hole 117 , the steering wheel 120 can only rotate relative to the steering wheel base 110 .

[0141] The support rod device 130 is hinged on the steering wheel 120, and the support rod device 130 is provided on both sides of the precast beam bearing area 124. The support rod devices 130 on both sides of the precast beam bearing area 124 are used to support the precast beam 400 from both sides of the precast beam. The support rod device 130 can change the angle by rotating so that it can be supported on both sides of the precast beam 400. The precast beam 400 can be fixed to the steering wheel 120 by the support rod device 130 to prevent the precast beam 400 from shaking relative to the steering wheel 120.

[0142] It should be noted that, except for the first rotating part, the other structures of the first precast beam transport support device 100a and the second precast beam transport support device 100b are basically the same (meaning that they are the same in structure, but differences in size are allowed, for example, the diameter and length of the steering shaft 125 disclosed in the two embodiments can be different, and the sizes of the two steering wheel bases 110 can also be different).

[0143] The first precast beam transport support device 100a and the second precast beam transport support device 100b disclosed in this embodiment, one has a sliding groove 114, and the other has a turning hole 117, that is, one can realize rotation and movement, and the other can only realize rotation. In actual application, the first precast beam transport support device 100a and the second precast beam transport support device 100b can support the two ends of the precast beam respectively. The front end in the travel direction is the first precast beam transport support device 100a, and the rear end is the second precast beam transport support device 100b. Of course, the second precast beam transport support device 100b can also be set at the front end, and the first precast beam transport support device 100a can be set at the rear end.

[0144] When the railway multifunctional flat car turns, the steering wheel base 110 fixed on the chassis floor 230 will change the angle with the car body, while the steering wheel 120 can remain stationary to keep the two steering wheels 120 fixed at both ends of the prefabricated beam 400 on the same straight line to prevent the prefabricated beam from interfering with the prefabricated beam due to the change in angle of the car body. At the same time, since the straight-line distance between the two prefabricated beam transport support devices changes when the railway multifunctional flat car turns, the steering wheel base 110 of the first prefabricated beam transport support device will not only change the angle with the car body, but also move along the steering wheel base 110 according to the decrease in the straight-line distance between the two prefabricated beam transport support devices to prevent the prefabricated beam 400 from being damaged due to the decrease in the straight-line distance between the two prefabricated beam transport support devices.

[0145] A wear-resistant bushing may be provided in the sliding groove 114 of the first precast beam transport support device 100a to improve the wear-resistant effect.

[0146] like Fig.13 and Fig.14 As shown, the steering wheel base 110 includes a longitudinal beam 111 and a transverse beam 112 that intersect each other. In this embodiment, the steering wheel base 110 is designed as a structure in which the longitudinal beam 111 and the transverse beam 112 cross each other, so that the steering wheel base 110 can provide a better support effect without significantly increasing the weight. The extension direction of the longitudinal beam 111 can be the length direction of the railway multifunctional flat car, and the extension direction of the transverse beam 112 can be the width direction of the railway multifunctional flat car.

[0147] In the initial state, the steering wheel 120 is arranged on the steering wheel base 110 in a direction parallel to the transverse beam 112. It should be noted that the initial state refers to the state when the steering wheel 120 is not rotated relative to the steering wheel base 110, that is, the state when the railway multifunctional flat car is running on a straight track and each train body is in the same straight line. That is, when the railway multifunctional flat car is running in a straight line, the steering wheel 120 is located directly above the transverse beam 112.

[0148] Furthermore, a side bearing base 113 is provided at the end of the transverse beam 112, and the width of the side bearing base 113 is greater than the width of the transverse beam 112. In the initial state, the steering wheel 120 extends above the side bearing base 113. Since the side bearing base 113 has a larger width than the transverse beam 112, when the steering wheel 120 moves and / or rotates, part of the structure can be kept overlapping with the side bearing base 113, so that the side bearing base 113 can provide support for the steering wheel 120 after the steering wheel 120 moves.

[0149] Further, such as Figure 12-16 As shown, a first wear plate 115 is provided on the side of the side bearing base 113 facing the steering wheel 120, and a second wear plate 126 is provided on the side of the steering wheel 120 facing the side bearing base 113. In this embodiment, the first wear plate 115 and the second wear plate 126 are fitted together to prevent the steering wheel 120 and the steering wheel base 110 from interfering during the relative movement. Specifically, the gap between the steering wheel 120 and the steering wheel base 110 can be adjusted by adjusting the thickness of the first wear plate 115 and / or the second wear plate 126. The first wear plate 115 and the second wear plate 126 are fitted together, so that when the steering wheel 120 moves relative to the steering wheel base 110, the first wear plate 115 and the second wear plate 126 rub against each other, thereby resisting wear, impact and vibration, and protecting the durability of the prefabricated beam transport support device.

[0150] In this embodiment, the steering wheel 120 may include a steering wheel body 121 and a limit stopper 122. The prefabricated beam bearing area 124 is located on the steering wheel body 121, and specifically, the prefabricated beam bearing area 124 may be arranged in the middle of the steering wheel body 121. The steering wheel body 121 may be formed by welding a plurality of plates.

[0151] The limit stopper 122 is arranged on the steering wheel body 121, and the limit stops 122 are arranged on both sides of the precast beam bearing area 124, and the two limit stops 122 form a limit for the precast beam. After the precast beam is placed in the precast beam bearing area 124, the two limit stops 122 can prevent the precast beam from moving and form a limit for the precast beam. In order to improve the reliability of the limit stopper 122, the limit stopper 122 can be supported by a plurality of diagonal bracing ribs, and the diagonal bracing ribs should be located on the side of the limit stopper 122 facing away from the precast beam bearing area 124. The limit stopper 122 is supported by the diagonal bracing ribs, so that even if the precast beam hits the limit stopper 122, the limit stopper 122 can maintain a certain resistance.

[0152] Furthermore, the prefabricated beam bearing area 124 may be provided with a wooden pad, which has a lower hardness. By supporting the prefabricated beam with the wooden pad, wear on the prefabricated beam can be avoided. In addition, the prefabricated beam is loaded on the upper part of the wooden pad, and the loading center of gravity of the prefabricated beam can be adjusted by adjusting the thickness of the wooden pad. A lifting ring 123 is provided on the steering wheel body 121 to facilitate the lifting equipment to lift the steering wheel 120 onto the steering wheel base 110 and install it.

[0153] In this embodiment, the steering wheel base 110 may include a bottom plate, an upper plate located above the bottom plate, and an intermediate support plate connected between the bottom plate and the upper plate. In this embodiment, the steering wheel base 110 is welded from a plurality of plates, which can reduce the weight of the steering wheel base 110 while ensuring the supporting effect.

[0154] The bottom plate is used to be fixed to the vehicle body by fasteners, and the upper plate is provided with fastener operation holes 116 at the corresponding positions of the fasteners. Since the distance between the bottom plate and the upper plate is not too large, the tightening wrench cannot operate the fastener through the space between the bottom plate and the upper plate. Therefore, in this embodiment, the fastener operation holes 116 are provided at the corresponding positions of the upper plate and the fasteners, and the tightening wrench can rotate the fasteners on the bottom plate through the fastener operation holes 116 above the upper plate.

[0155] like Fig.17 As shown, the support rod device 130 may include a support rod body and a support pad assembly 135, and the support rod body includes a support rod sleeve 131, a first connecting rod 132, a second connecting rod 133 and a rotating shaft seat 134. The support rod sleeve 131 has a first threaded hole and a second threaded hole, one end of the support rod sleeve 131 is the first threaded hole, and the other end is the second threaded hole, and the first threaded hole and the second threaded hole have opposite rotation directions.

[0156] The first connecting rod 132 is threadedly matched with the first threaded hole, the second connecting rod 133 is threadedly matched with the second threaded hole, and the support pad assembly 135 is connected to the second connecting rod 133 to support the prefabricated beam. The rotating shaft seat 134 is arranged on the steering wheel 120, and the first connecting rod 132 is hinged to the rotating shaft seat 134.

[0157] The first connecting rod 132 is connected to the rotating shaft seat 134, and the rotating shaft seat 134 is arranged on the steering wheel 120, thereby realizing the hinge connection between the support rod body and the steering wheel 120, so that the support rod body can be rotated through the rotating shaft seat 134. After the precast beam is placed, the support rod body can be rotated to make the support pad assembly 135 at the end of the second connecting rod 133 abut against the side of the precast beam, thereby completing the support of the side of the precast beam. Usually, the support pad assembly 135 can be abutted against the lower edge of the precast beam.

[0158] Since the specifications of the prefabricated beams are different, the required lengths of the brace bodies are different. In this embodiment, the first connecting rod 132 and the second connecting rod 133 are installed at both ends of the brace sleeve 131. Since the first threaded hole and the second threaded hole have opposite rotation directions, the first connecting rod 132 and the second connecting rod 133 can be moved synchronously by rotating the brace sleeve 131, and the moving directions are opposite, that is, they move closer to each other (shortening the length of the brace body) and move away from each other (increasing the length of the brace body). By rotating the brace sleeve 131, the length of the first connecting rod 132 and the second connecting rod 133 extending outside the brace sleeve 131 can be changed, thereby adjusting the length of the brace body to adapt to the prefabricated beams of corresponding specifications.

[0159] In order to improve the supporting effect, the brace device 130 on either side of the precast beam bearing area 124 includes two brace bodies, which are connected to the same brace pad assembly 135. When the two brace bodies are connected to the same brace pad assembly 135, the two brace bodies are in a herringbone shape, that is, the two brace bodies are arranged at an acute angle.

[0160] like Fig.18 As shown, in this embodiment, the pad assembly 135 may include a pad support body 1352, a pad body 1351 and a support rod hinge seat 1353. Among them, the pad support body 1352 serves as the supporting body of the pad assembly 135, and is used to provide an installation foundation for other components. The pad body 1351 is arranged on the first side of the pad support body 1352, and the pad body 1351 is a flexible material body. The pad body 1351 is used to abut against the prefabricated beam. Since the pad body 1351 is a flexible material body, the pad body 1351 abuts against the prefabricated beam, which has a certain buffering effect, and the non-rigid contact can protect the prefabricated beam from being damaged due to inertia, impact, etc.

[0161] The support rod hinge seat 1353 is provided with a connection hole 1354 hinged to the two support rod bodies, and the second connection rods 133 of the two support rod bodies are respectively connected to the two connection holes 1354 through the hinge shaft. Specifically, the support rod hinge seat 1353 includes two support plates, and a space is formed between the two support plates for the end of the second connection rod 133 to be inserted, and the connection hole 1354 passes through the two support plates.

[0162] The second connecting rod 133 of one of the support rod bodies is hinged to one of the connecting holes 1354 through a fixed pin. When the connecting end of one of the second connecting rods 133 extends between the two support plates and ensures that the upper hole of the connecting end of the second connecting rod 133 is connected to the connecting holes 1354 on the two support plates, a fixed pin can be inserted for hinge connection.

[0163] The second connecting rod 133 of the other support rod body is hinged to the other connecting hole 1354 through the sliding pin 1355, and the sliding pin 1355 is slidably matched on the support pad support body 1352. That is, in this embodiment, one second connecting rod 133 is hinged through the fixed pin, and the other second connecting rod 133 is hinged through the sliding pin 1355.

[0164] When the railway multi-purpose flat car is not transporting precast beams (for example, when returning empty), the strut device 130 needs to be laid down to prevent the strut device 130 from shaking and colliding with other structures. Since the two strut bodies are connected to a strut pad assembly 135, when the strut device 130 needs to be laid down, at least one of the strut bodies needs to be disassembled from the strut pad assembly 135, otherwise it cannot be laid down. In this embodiment, only the strut body hinged by the sliding pin 1355 needs to be disassembled, and the other strut body hinged by the fixed pin can remain connected to the strut pad assembly 135 without disassembly. Fig. 9 As shown, the brace body on the left is disconnected from the brace pad assembly 135 , while the brace body on the right remains connected to the brace pad assembly 135 .

[0165] like Fig.17 As shown, the rotating shaft seat 134 can output swinging along the width direction of the vehicle body (i.e., the swinging plane is the width direction of the vehicle body), and the support rod body is hinged with the output end of the rotating shaft seat 134, so that the support rod body can swing along the length direction of the vehicle body relative to the output end (i.e., the swinging plane is the length direction of the vehicle body). That is, the support rod body can swing along the width direction and length direction of the vehicle body through the connection with the rotating shaft seat 134. By swinging along the width direction of the vehicle body (i.e., the rotation axis is parallel to the length direction of the vehicle body), the support pad assembly 135 can be abutted against the prefabricated beam; by swinging along the length direction of the vehicle body (i.e., the rotation axis is parallel to the width direction of the vehicle body), the support rod body can be laid on the vehicle body and extended along the length direction of the vehicle body.

[0166] In order to fix the fallen support rod body, in this embodiment, the precast beam transport support device may further include a support rod support 140 for being arranged on the vehicle body, and a slot is formed on the top of the support rod support 140. The opening of the slot may be designed as a flared interface to facilitate the insertion of the support rod device 130 into the slot. In this embodiment, when the support rod device 130 is idle, it can be inserted into the slot of the support rod support 140, and the support rod body of the support rod device 130 can be fixed by the support rod support 140, and specifically, the support rod sleeve 131 can be inserted into the slot. In addition, the support rod support 140 and the rotating shaft seat 134 may not be on the same straight line (that is, the support rod support 140 is not on the connecting line of the two rotating shaft seats 134 on the same side of the precast beam bearing area 124, but the deviation distance cannot be too large, otherwise the support rod body cannot be inserted into the slot), and the angle formed can play a role in fixing the support rod body.

[0167] like Fig.18 As shown, a guide rod is provided on the support pad support body 1352, and a sliding pin 1355 can be slidably sleeved on the guide rod, and the guide rod can be fixed on the support plate, and the support plate is fixed on the support pad support body 1352. The sliding pin 1355 and the guide rod are coaxially arranged with one of the connection holes 1354, and the sliding pin 1355 can be slid into the connection hole 1354 or slid out of the connection hole 1354 by sliding the sliding pin 1355. After sliding into the connection hole 1354, the connection with the support rod body can be realized, and after sliding out of the connection hole 1354, the disassembly from the support rod body can be realized, which improves the disassembly and assembly efficiency with the support rod body.

[0168] In order to ensure that the sliding pin 1355 will not be easily disengaged after being connected to the support rod body, in this embodiment, the support pad support body 1352 is movably connected with a sliding pin baffle 1356, and after the sliding pin 1355 is inserted into the connection hole 1354, the sliding pin baffle 1356 is used to resist the sliding pin 1355. Specifically, the sliding pin baffle 1356 can be hinged on the support pad support body 1352, and when the support rod device 130 is erected for use, the sliding pin baffle 1356 will swing downward under the action of gravity and overlap on the guide rod, and can resist the exit path of the sliding pin 1355, preventing the sliding pin 1355 from falling out of the connection hole 1354, thereby improving the safety of use.

[0169] like Fig.17 As shown, the support rod sleeve 131 is provided with a collar 136 and / or an auxiliary rotation socket 137. The collars 136 on the two support rod bodies of the support rod device 130 can be connected by a rope to prevent the support rod sleeve 131 from rotating and ensure the supporting effect. The auxiliary rotation socket 137 can be inserted with a tool such as a chisel to rotate the support rod sleeve 131 by levering, thereby achieving the purpose of saving effort.

[0170] It should be noted that the railway multifunctional flat car should also include a bogie, a braking system, a coupler buffer device, etc. The bogie can be a three-piece bogie with an axle weight of 23t, mainly composed of axles, rockers, side frames, cross rods, braking devices, rubber pads, elastic side bearings, etc. The braking system can be composed of a 120-type control valve, a 305mm diameter integrally spun sealed brake cylinder, a stainless steel embedded air storage cylinder, an ST2-250 type bidirectional brake shoe clearance adjuster, a KZW-C type empty and loaded vehicle automatic adjustment device, a freight car derailment automatic braking device, an A-type stainless steel ball core angle plug door and a combined dust collector, etc. The coupler buffer device can be mainly composed of a coupler, a buffer, etc. It can be understood by those skilled in the art that the bogie, the braking system, and the coupler buffer device can all be selected from the commonly used equipment in the prior art, and the details thereof will not be repeated herein.
