Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of locomotive technology, in particular to a tail structure and a locomotive. BACKGROUND

[0002] In railway transportation, multiple locomotives are often coupled together. For example, an eight-axle locomotive is formed by coupling two identical four-axle single-cab locomotives through a middle coupling and a rubber coupling windscreen. Each car is a complete system, and the locomotive can be controlled by the driver in any one of the cab ends. An internal electrical reconnection cable and a reconnection pipeline of the air brake system are arranged between the two locomotives. Due to the limited space of the end face of the car body, and the fact that the reconnection connection part is in a moving state during operation, the arrangement of the electrical reconnection cable and the reconnection pipeline of the air brake system has always been a difficulty.

[0003] The electrical reconnection cable is often connected by an electrical connector at the tail. At present, the eight-axle locomotive often uses a wiring box welded on one side of the end face of the car body. The electrical connector is wired from the bottom and side of the wiring box. After the reconnection cable is wired from the wiring box on one side of the A car to the wiring box on the other side of the B car, the two cars are reconnected. This wiring structure is complex to operate and occupies a large space. The connection between the cable and the electrical connector is prone to bending and stress, resulting in unstable signals, and the cable is prone to friction and wear if not properly tied. At the same time, the exposed part of the cable is long, affecting the aesthetics. SUMMARY

[0004] The purpose of the present disclosure is to provide a tail structure and a locomotive to alleviate the technical problems of the existing reconnection locomotive tail end wired from the bottom and side of the wiring box, complex wiring structure, and the connection between the cable and the electrical connector prone to bending and stress in the prior art.

[0005] To achieve the above purpose, the present disclosure provides a tail structure, which comprises a first plate part provided with a wiring hole, side walls provided on both sides of the first plate part, and a plurality of partitions provided on the lower surface of the first plate part. A second plate part is arranged between two adjacent partitions. The second plate part can be bent so that at least part of the second plate part is arranged at an angle with the first plate part. The second plate part is provided with a mounting hole for mounting an electrical connection component, and the mounting hole is opposite and communicates with the wiring hole.

[0006] In one embodiment of the present disclosure, one end of the second plate part away from the first plate part is provided with a drainage hole; and the side of the second plate part away from the first plate part is provided with a baffle corresponding to the drainage hole.

[0007] In one embodiment of the present disclosure, the rear structure further comprises a fixing support connected with the second plate part, and the fixing support is used to connect with the outgoing line of the electrical connection component.

[0008] In one embodiment of the present disclosure, the rear structure further comprises a connecting piece, the fixing support is provided with a connecting hole, and the connecting piece passes through the connecting hole to connect two adjacent fixing supports together.

[0009] In one embodiment of the present disclosure, the rear structure further comprises a cover installed on the surface of the first plate part away from the second plate part, and the cover comprises a cover body and a handle, the cover body comprises a support frame and a cover body, the support frame is connected with the first plate part, the support frame is provided with an opening, the cover body is arranged on the opening, the cover body is provided with a wire inlet channel, the wire inlet channel is communicated with the wire outlet hole, and the handle is connected with the support frame.

[0010] In one embodiment of the present disclosure, the cover body comprises a plurality of cover plates, the plurality of cover plates are spliced to cover the opening of the support frame, and the wire inlet channel is located at the splicing position of two adjacent cover plates.

[0011] Based on the above purpose, the present disclosure further provides a locomotive comprising the rear structure.

[0012] In one embodiment of the present disclosure, the number of the rear structures is two, and the two rear structures are symmetrically arranged along the width direction of the locomotive.

[0013] In one embodiment of the present disclosure, the first plate parts of the two rear structures are integrally formed.

[0014] In one embodiment of the present disclosure, the locomotive further comprises a chassis, a side wall and a rear end wall, the rear structure is fixedly connected with the chassis, the first plate part is coplanar with the top plate of the chassis, and the side wall and the rear end wall are both fixedly connected with the upper surface of the first plate part.

[0015] The present disclosure has the following beneficial effects:

[0016] The tail structure provided by the present disclosure comprises a first plate part provided with a lower wire hole, side walls provided on both sides of the first plate part, and a plurality of partitions provided on the lower surface of the first plate part. A second plate part is provided between two adjacent partitions. The second plate part can be bent so that at least part of the second plate part is arranged at an angle with the first plate part.

[0030] Reference Figures 1 to 8As shown, the embodiment provides a tail structure, which comprises a first plate part 101, the first plate part 101 is provided with a lower line hole 103, both sides of the first plate part 101 are provided with side wall plates 104, the lower surface of the first plate part 101 is provided with a plurality of partition plates 105, a second plate part 102 is arranged between two adjacent partition plates 105, the second plate part 102 can be bent, so that at least part of the second plate part 102 is arranged at an angle with the first plate part 101, the second plate part 102 is provided with a mounting hole 106 for mounting an electrical connecting component 107, the mounting hole 106 is opposite to and communicates with the lower line hole 103.

[0031] The tail structure provided by the embodiment is used, installed on the underframe 201 of a locomotive, the electrical connecting component 107 is installed on the mounting hole 106, the cables inside the locomotive are uniformly led into the space between the first plate part 101 and the second plate part 102 from the lower line hole 103 on the first plate part 101, and are connected to the electrical connecting component 107, the structure is simple, the operation is convenient, since the second plate part 102 can be bent, and the mounting hole 106 is opposite to and communicates with the lower line hole 103, the second plate part 102 can be bent according to the installation requirement of the electrical connecting component 107 and the direction of the cables, so that it is arranged at an angle with the first plate part 101, the cables can be connected to the electrical connecting component 107, and there is no obvious bending, so that the stress of the bending of the cables and the electrical connecting component 107 is avoided, and the signal stability is ensured.

[0032] In some embodiments, the partition plates 105 are welded with the first plate part 101 and the second plate part 102, so as to divide the space between the first plate part 101 and the second plate part 102 into a plurality of sub-cavities, by arranging the partition plates 105, the connection firmness of the whole tail structure can be improved.

[0033] In some embodiments, the number of the second plate parts 102 is multiple, the angles of the second plate parts 102 at different positions can be the same or different, as long as the installation requirement of the electrical connecting component 107 can be met and the connection of the heavy-haul cable 206 can be naturally bent.

[0034] In some embodiments, referring to Figure 4 As shown, the second plate part 102 is provided with a mounting plate 108, the mounting plate 108 can be welded with the second plate part 102, the mounting plate 108 is provided with a mounting through hole, the mounting through hole communicates with the mounting hole 106 on the second plate part 102, and the electrical connecting component 107 is mounted on the mounting plate 108.

[0035] Illustratively, the electrical connecting component 107 comprises a socket and a plug.

[0036] In some embodiments, the second plate part 102 is further provided with an identification mounting hole 109 for mounting a nameplate.

[0037] In some embodiments, the first plate part 101 sets the downline hole 103 at different positions according to the wiring requirement, and the opening size of the downline hole 103 should be as large as possible under the premise of meeting the mechanical strength requirement, so as to facilitate wiring installation and maintenance.

[0038] In one embodiment, the end of the second plate part 102 away from the first plate part 101 is provided with a drainage hole 110, and the side of the second plate part 102 away from the first plate part 101 is provided with a baffle 111 corresponding to the drainage hole 110.

[0039] Since the second plate part 102 is arranged at an angle between the first plate part 101, one end of the second plate part 102 is away from the first plate part 101, and the other end of the second plate part 102 is close to the first plate part 101, that is, the position of the end of the second plate part 102 away from the first plate part 101 is lower than the position of the other end, by setting the drainage hole 110 at the end of the second plate part 102 away from the first plate part 101, and the mounting hole 106 is set at the end of the second plate part 102 close to the first plate part 101, it is convenient to drain the water entering the sub-cavity, prevent water from flowing into the electrical connection component 107, so as to provide a normal working environment for the electrical connection component 107.

[0040] By setting the baffle 111, and the baffle 111 corresponds to the drainage hole 110, the water flowing out of the drainage hole 110 can be blocked and guided, further preventing water from flowing into the electrical connection component 107.

[0041] For example, referring to Figure 3 As shown in the figure, the baffle 111 is a V-shaped baffle.

[0042] In one embodiment, the tail structure further comprises a fixing support 112, the fixing support 112 is connected with the second plate part 102, and the fixing support 112 is used for connecting with the outgoing line of the electrical connection component 107.

[0043] By setting the fixing support 112, the outgoing line of the tail part under the car of the electrical connection component 107 can be directly tied.

[0044] For example, referring to Figure 5 As shown in the figure, the fixing support 112 comprises a horizontal plate 113, a vertical plate 114 and a wire tying plate 115, the horizontal plate 113 is substantially perpendicular to the vertical plate, the wire tying plate 115 is connected with the horizontal plate 113, the wire tying plate 115 is substantially parallel to the vertical plate 114, and the vertical plate 114 is fixedly connected with the second plate part 102. In use, the vertical plate 114 is welded at a suitable position, so as to tie the outgoing line of the tail part under the car of the electrical connection component 107, ensure that the heavy cable 206 is fixed firmly and naturally curved, and avoid stress and friction wear.

[0045] For example, the wire tying plate 115, the horizontal plate 113 and the vertical plate 114 are integrally formed to improve the mechanical strength of the fixing bracket 112.

[0046] In one embodiment, the rear structure also includes a connector, and the fixing bracket 112 is provided with a connecting hole 116, through which the connector passes to connect two adjacent fixing brackets 112 together.

[0047] When one fixed bracket 112 is insufficient to secure the reconnected cable 206 and two fixed brackets 112 cannot be welded to the second plate 102, a connector and a connecting hole 116 can be used to connect two adjacent brackets together. For example, the connector includes a bolt and a nut. The bolt passes through the conductive connecting hole 116 of the two fixed brackets 112, and the nut engages with the bolt, thereby indirectly connecting the fixed bracket 112 to the second plate 102.

[0048] It should be noted that the fixing bracket 112 can also be a wire clamp, or a wire clamp can be installed on the fixing bracket 112 to bind the reconnected cable 206.

[0049] In one embodiment, see Figure 6 As shown, the rear structure also includes a cover, which is installed on the surface of the first plate 101 opposite to the second plate 102. The cover includes a cover body and a handle 117. The cover body includes a support frame 118 and a cover body. The support frame 118 is connected to the first plate 101 and has an opening. The cover body covers the opening and has a wire inlet channel 121 that communicates with the lower wire hole 103. The handle 117 is connected to the support frame 118.

[0050] By setting a cover, the lower wire hole 103 can be sealed to prevent water ingress as much as possible. This embodiment adopts a combination of waterproofing and drainage, that is, the cover is combined with the drain hole 110 and the baffle 111 to ensure that the electrical connection component 107 can work normally.

[0051] For example, see Figure 6 As shown, the cover is a rectangular frame structure, and the bottom of the cover is provided with flanges 119 around its perimeter. Each flange 119 has a first mounting hole 122. (See attached image.) Figure 1 As shown, the first plate 101 is provided with a second mounting hole 123. During installation, the cover is placed on the first plate 101 to ensure that the cover covers the lower wire hole 103 and the first mounting hole 122 is aligned with the second mounting hole 123. The cover is fixedly installed on the first plate 101 using fasteners such as bolts and nuts.

[0052] In use, the cable drawn from the vehicle can be tied on the handle 117, and the handle 117 is fixedly connected with the support frame 118, so as to fix the position of the cable and prevent the cable from being rubbed and abraded.

[0053] It should be noted that the handle 117 can also be connected with the support frame 118 through a damping rotating shaft, so as to adjust the angle and position of the handle 117 according to the running direction of the cable, so as to prevent the cable from being excessively bent or subjected to a large force, and improve the service life and signal stability of the cable.

[0054] Of course, in order to prevent the handle 117 from shaking during the operation of the vehicle, the handle 117 can also be fixed on the support frame 118 by using fasteners such as bolts and nuts after the angle and position of the handle 117 are adjusted, so as to prevent the handle 117 from shaking and fix the position of the cable and prevent the cable from being rubbed and abraded.

[0055] In an embodiment, referring to Figure 6 The cover body includes a plurality of cover plates 120, and the plurality of cover plates 120 are spliced to cover the opening of the support frame 118, and the wire inlet channel 121 is located at the splicing position of two adjacent cover plates 120.

[0056] For example, at least one side edge of the cover plate 120 is provided with a notch, and the notch is a semicircular notch, and the semicircular notches on the two cover plates 120 are opposite to each other after the two cover plates 120 are spliced to form the wire inlet channel 121. By splicing, the position of the wire inlet channel 121 can be changed, so that the placement position of the cover plate 120 can be flexibly selected according to the wiring requirement.

[0057] When the cable is in the wire inlet channel 121, a protective material is arranged between the wire inlet channel 121 and the cable to protect the cable, and when the cable is not in the wire inlet channel 121, a joint type component or a sealing plug can be used to plug the wire inlet channel 121 to play a sealing role and prevent water from entering.
