Embodiments of the present invention will now be described with reference to fig. 1 to 4. It should be understood that the following description is only exemplary embodiments of the present invention and does not constitute any particular limitation of the present invention.
As shown in fig. 1, according to an embodiment of a first aspect of the present invention, a rail vehicle equipment hanger frame 100 is provided. Specifically, the rail vehicle equipment hanger frame 100 generally includes a pair of side beams 102, a pair of equipment hanger stringers 104, and at least one first cross beam 106.
The pair of device hanging longitudinal beams 104 are disposed between the pair of side beams 102, that is, the pair of side beams 102 are located outside the pair of device hanging longitudinal beams 104. Further, a pair of equipment hanger stringers 104 are connected to a pair of edge beams 102 so that they can be combined together to form a longitudinal load beam. In the practical application process, the longitudinal bearing beam formed by the equipment hanging longitudinal beam 104 and the edge beam 102 together can provide a structure meeting the strength and fatigue requirements required by hanging heavy-load equipment, and meanwhile, the arrangement structure can also meet the requirement of longitudinal arrangement of equipment installation.
As further shown in fig. 1, in the embodiment of the present invention, the first cross member 106 is connected between the pair of side members 102, so that the pair of side members 102, the pair of equipment hanger stringers 104, and the first cross member 106 together form a modular frame structure. In practical application, the modularized hanging frame can be installed between a pair of underframe boundary beams of the underframe of the car body according to requirements, so that the modularized installation effect is realized.
More specifically, in one embodiment of the present invention, as shown in fig. 1-3, each of the pair of side beams 102 may be configured as a channel beam structure, and the openings of the pair of side beams 102 of the channel beam structure are opposite to each other. In other words, the outer walls of the pair of side beams 102 together form the overall outer edge of the rail vehicle equipment hanger frame 100, and the openings of the channel-type structure of the side beams 102 open toward each other along the lateral direction of the rail vehicle equipment hanger frame 100.
Further, each of the pair of equipment hanger stringers 104 may also be configured in a channel beam structure, and the openings of the pair of equipment hanger stringers 104 of the channel beam structure are opposite to each other. In other words, the inner walls of the pair of equipment hanger stringers 104 form the inner edges of the rail vehicle equipment hanger frame 100, and the openings of the channel-like structure of the equipment hanger stringers 104 open away from or opposite each other in the transverse direction of the rail vehicle equipment hanger frame 100.
That is, as shown in fig. 2, for example, the opening of the side member 102 on one side (e.g., the left side in fig. 2) and the opening of the equipment hanging side member 104 on the one side are opposed to each other; the opening of the side member 102 on the other side (e.g., the right side in fig. 2) and the opening of the equipment hanging side member 104 on the one side face each other.
Further, the channel beam structures of the pair of side beams 102 and the channel beam structures of the pair of equipment hanger stringers 104 are butt welded to each other (e.g., at weld S) to enable the formation of a pair of longitudinal load beams of a square beam structure. As described above, as shown in fig. 2, the opening of the side member 102 on one side (for example, the left side in fig. 2) and the opening of the equipment hanging side member 104 on the one side are opposed to each other, and the side member 102 on the one side and the equipment hanging side member 104 on the one side are butt-welded (for example, by assembly welding) to each other to form a structure of a square beam, which is used as one set of longitudinal load beams for hanging equipment. Similarly, the opening of the side beam 102 on the other side (e.g., the right side in fig. 2) and the opening of the equipment hanger rail 104 on the one side are opposed to each other, and the side beam 102 on the one side and the equipment hanger rail 104 on the one side are butt-welded (e.g., by assembly welding) to each other to form a structure of a square beam that is used as another set of longitudinal load-bearing beams for hanger equipment.
In other words, in the embodiment shown in FIG. 2, a pair of side beams 102 and a pair of equipment hanger stringers 104 are butt welded together to form two sets of longitudinal load carrying beams for hanging equipment. The two sets of longitudinal load beams are spaced from each other in a transverse direction of the rail vehicle equipment hanger frame 100. After being assembled to the underframe boundary beam of the underframe of the railway vehicle body, the equipment (such as heavy-duty equipment) under the vehicle can be hung between the two groups of longitudinal bearing beams, so that the longitudinal arrangement requirement of the equipment under the vehicle is met, and a longitudinal arrangement mounting point is provided for the equipment under the vehicle.
Moreover, two groups of longitudinal bearing beams formed by butt welding the pair of side beams 102 and the pair of equipment hanging longitudinal beams 104 are respectively of a square beam structure, and the square beam structure has better rigidity and higher hanging stability, so that the embodiment of the invention can realize the effect of effectively and stably hanging the heavy-load equipment.
Referring back to FIG. 1, in an embodiment of the present invention, the rail vehicle equipment hanger frame 100 may include two first cross members 106 as described above. Specifically, the two first cross members 106 may be connected in parallel with each other between the pair of side beams 102, such that the pair of side beams 102, the pair of equipment hanger stringers 104, and the two first cross members 106 together form a modular frame structure. And further, the two first cross members 106 may be provided at opposite ends of the pair of equipment hanger stringers 104 in the longitudinal direction of the rail vehicle equipment hanger frame 100.
Specifically, a first cross beam 106 may be disposed at two ends of the pair of equipment hanging longitudinal beams 104 located at the first end, and another first cross beam 106 may be disposed at two ends of the pair of equipment hanging longitudinal beams located at the second end. In this way, the two first cross members 106 can be extended in the lateral direction of the rail vehicle equipment hanger frame 100 as a whole and at the same time spaced apart from each other in the longitudinal direction of the rail vehicle equipment hanger frame 100.
According to the embodiment, during the actual operation after the rail vehicle equipment hanging frame 100 is assembled to the vehicle body underframe, in order to avoid the impact damage of the heavy load equipment to the vehicle body steel structure along the longitudinal direction during the vehicle operation, the first cross beams 106 with certain wall thickness are respectively arranged at the two end parts of the equipment hanging longitudinal beam 104. In this manner, rail vehicle equipment hanger frame 100 is provided with improved resistance to longitudinal impact.
With further reference to fig. 2 and 3, in an embodiment of the present invention, each equipment hanger rail 104 may have a stud 108 disposed therein. Specifically, the studs 108 may be connected between the top and bottom interior surfaces of the equipment hanger rail 104 and arranged along the direction of extension of the equipment hanger rail 104. In other words, the studs 108 are ribs arranged in a vertical direction, and the studs 108 may be arranged along a longitudinal direction of the rail vehicle equipment hanger frame 100. According to this embodiment, since the stud 108 is provided inside the equipment hanger rail 104, the rigidity of the equipment hanger rail 104 can be effectively increased. In addition, the arrangement of the studs 108 can provide a mounting surface for a rotation prevention block (described below) to be mounted later on the basis of improving the rigidity, so that the studs are used for preventing rotation of bolts when the equipment under the vehicle is hoisted.
Specifically, as shown in fig. 2 and 3, the studs 108 can divide the longitudinal carrier beam formed by the edge beam 102 and the equipment hanger rail 104 into an inner section I and an outer section II in the transverse direction of the rail vehicle equipment hanger frame 100. That is, each set of longitudinal load beams comprises one inboard section I and one outboard section II, respectively. In the embodiment shown in fig. 2, the two sets of longitudinal load beams comprise in total two inner sections I and two outer sections II. And, two inner sections II are located between two outer sections II, thereby forming the structure shown in fig. 2.
As shown in fig. 2 and 3, in this embodiment, the inboard section I may be defined by an elevation of the equipment hanger rail 104, a portion of a top surface of the equipment hanger rail 104, a portion of a bottom surface of the equipment hanger rail 104, and the studs 108 as described above. In the case of the outer section II, the outer section II may be defined by the studs 108, another part of the top surface of the device hanger rail 104, another part of the bottom surface of the device hanger rail 104, and the edge beam 102 as described above. In other words, for each set of longitudinal load beams, it may comprise an inner section I and an outer section II, respectively shaped like a beam structure of a mouth. With this configuration, the rigidity of the equipment hanger rail 104 can be effectively increased.
As further shown in fig. 2 and 3, in the embodiment of the present invention, a plurality of equipment mounting holes 110 may be formed on the bottom surface of the equipment hanging longitudinal beam 104 in the inner section I, and the under-vehicle equipment may be mounted and hung through the equipment mounting holes 110. In addition, a plurality of fabrication holes 112 may be formed on the vertical surface of the equipment hanging longitudinal beam 104 in a matching manner. The tooling holes 112 may be provided to enable access to the equipment mounting holes 110, thereby enabling an operator or operating equipment to operate and inspect fasteners (such as bolts) at the equipment mounting holes 110 via the tooling holes 112.
It should be understood herein that the number, location, shape, size, etc. of the equipment mounting holes 110 and the tooling holes 112 are not intended to limit the present invention in any way, and may be set or selected according to the particular application. In other words, in the embodiment of the present invention, it is only necessary that an operator or an operating device be able to operate and inspect the fastener at the device mounting hole 110 via the tooling hole 112.
Referring now to fig. 3, in an embodiment of the present invention, an anti-rotation block 114 may be disposed in the inboard section I separated by the longitudinal load beams. Specifically, the anti-rotation block 114 may be welded to the studs 108 and the bottom surface of the equipment hanger rail 104, such that the anti-rotation block 114 may rest against the studs 108 and simultaneously be supported on the bottom surface of the equipment hanger rail 104.
During a particular assembly process, the anti-rotation block 114 can be in abutting engagement with the bolt anti-rotation block 116 located at the equipment mounting hole 110. Upon assembly, a fastener, such as a mounting bolt 118, may abut against the rotation stop flange 120 of the bolt rotation stop block 116, with the mounting bolt 118 extending through the equipment mounting hole 110 and out the bottom surface of the equipment hanger rail 104. At this time, the edge of the bolt rotation preventing block 116 abuts against the rotation preventing block 114, and the rotation preventing block 114 limits the bolt rotation preventing block 116 to prevent the rotation thereof. During assembly, the equipment is mounted by tightening the mounting bolt 118 with a nut.
Referring now to FIG. 1, in an embodiment of the present invention, rail vehicle equipment hanger frame 100 further comprises at least one second cross-member 122 and at least one third cross-member 124. Specifically, the second cross member 122 may be connected between a pair of equipment hanger stringers 104. According to this embodiment, by providing the second cross member 122 between the pair of equipment hanger stringers 104, the rigidity of the structure can be effectively improved. Further, along the longitudinal direction of the rail vehicle equipment hanger frame 100, a third cross member 124 may be located outside the two first cross members 106, and the third cross member 124 may be connected between the pair of side members 102. Similarly to the second cross member 122, by providing the third cross member 124 between the pair of side members 102, the rigidity of the structure can be effectively improved as well.
It should be understood that the number of the second cross beams 122 and the third cross beams 124 can be set according to specific use conditions, and the invention is not limited to certain specific number, and only needs to improve the structural rigidity and meet the hanging requirement.
In one embodiment of the present invention, the second beam 122 and the third beam 124 may be formed by bending stainless steel plates. For example, the second beam 122 and the third beam 124 may be 4mm stainless steel bent beams. It should be understood that the material, size and forming manner of the second cross member 122 and the third cross member 124 can be set according to specific situations, and the present invention is not limited to the above-mentioned embodiments.
Furthermore, in an embodiment of the present invention, the first cross beam 106 may be a square beam structure formed by tailor welding carbon steel plates for bearing impact load. The pair of side members 102 and the pair of equipment hanging side members 104 may be formed by bending carbon steel plates. Similarly, it should be understood that the materials, dimensions and forms of the pair of side rails 102, the pair of equipment hanger stringers 104 and the first cross rail 106 may be set according to specific circumstances, and the present invention is not limited to the above-described embodiments.
According to the above embodiments, the integral frame of the rail vehicle equipment hanging frame 100 provided by the embodiment of the invention is formed by bending and welding the stainless steel plate or the carbon steel plate, so that the structure forming is simpler and more convenient.
As shown in fig. 4, according to an embodiment of the second aspect of the present invention, there is also provided a rail vehicle body chassis 200. Specifically, the rail vehicle body underframe 200 includes a pair of underframe side rails 202 and the rail vehicle equipment hanger frame 100 as described above. As shown in fig. 1, the rail vehicle equipment hanger frame 100 may be disposed between a pair of undercarriage side rails 202 and connected to the pair of undercarriage side rails 202 by a pair of side rails 102.
During actual assembly, a pair of undercarriage side rails 202 of a rail vehicle body undercarriage 200 may be coupled together by an undercarriage cross member 204. For example, the undercarriage cross members 204 may be formed by bending a 4mm stainless steel plate in most cases and may be arranged laterally between the undercarriage side members 202 according to the installation requirements of the equipment. When the installation point is arranged for 4 ton equipment, the 4mm stainless steel beam has insufficient rigidity and strength and can not provide the requirement of longitudinal arrangement of equipment installation, so the rail vehicle equipment hanging frame 100 is additionally arranged in the rail vehicle body underframe 200. During assembly, the edge beam 102 of the rail vehicle equipment hanger frame 100 is shaped to match the contoured shape of the undercarriage edge beam 202 and can be connected by connectors to facilitate assembly.
Further, according to an embodiment of the third aspect of the present invention, there is also provided a rail vehicle. Wherein the rail vehicle comprises a rail vehicle body underframe 200 as described above.
