It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] See also Figure 1-8The object of the present invention is to provide a tram vehicle roof wire tube jumper device, comprising a wire tube fixing bracket 1, a wire passing bracket and a wire tube installed on the wire passing bracket.

[0022] The wire-passing bracket includes a fixed wire-passing bracket 2 and a sliding wire-passing bracket; the sliding wire-passing bracket includes a first sliding wire-passing bracket 3 and a second sliding wire-passing bracket 4. Specifically, the entire device is arranged between tram vehicles (the top between two carriages), and each set of devices includes four wire tube fixed brackets 1, a fixed wire-passing bracket 2, two first sliding wire-passing brackets 3 and two second sliding wire-passing brackets 4. Various signal lines and power cables are passed through the wire tube, and both ends of the wire tube are connected to the wire tube connection box of the two adjacent carriages through joints; the wire-passing bracket plays the role of fixing and supporting the wire tube, and can protect the internal cables when the tram is moving steadily or turning.

[0023] The device can fixedly support 4 groups of wire tubes, each group of wire tubes includes a number of wire tubes. The number of wire tube groups and the number of wire tubes in each group can be increased or decreased according to actual conditions. The attached figure only demonstrates the train configuration of three groups of wire tubes.

[0024] See attached Figure 1 and attached Figure 4 When one end of the wire tube is far away from another car, a wire tube fixing bracket 1 is installed 300mm away from the wire tube joint. The pipe section between the wire tube fixing bracket 1 and the wire tube joint is always stationary relative to the train. This setting can fix the longer wire tube in sections, ensure that the wire tube is fixed reliably, and avoid interference.

[0025] See attached Figure 1 , Attachment Figure 4 and attached Figure 5 The wire tube fixing bracket 1 includes two first connecting pieces fixedly connected to the top of the train and a clamping block located between the two first connecting pieces; specifically, the first connecting piece is an "L"-shaped metal connecting piece, and the clamping block is installed between the two "L"-shaped metal connecting pieces; the two "L"-shaped metal connecting pieces and the clamping block are connected by bolts. The clamping block is provided with a plurality of through holes penetrating the clamping block, and the wire tube can be inserted into the through holes, so as to achieve the purpose of fixing the wire tube.

[0026] See attached Figure 1 -Attached Figure 6The fixed wire crossing bracket 2 includes a fixed base installed on the top of the train, and a pillar 201 is fixedly connected to the top of the fixed base. The pillar 201 has a certain height, and the height is set according to the height of the interface on the wire pipe connection box. The height of the pillar 201 should ensure that the wire pipe can be normally bridged between trains to avoid interference with the folding shed and elastic rubber structure. At the same time, the height of the pillar 201 should meet the limit (the locomotive and vehicle are running normally on the track to prevent the locomotive and vehicle from hitting the buildings and equipment on the adjacent line. The outline dimension line that is not allowed to be exceeded for the locomotive and vehicle and the buildings and equipment close to the line is called the limit) requirements. The side of the pillar 201 close to the other carriage is fixedly connected to the wire clamp bracket 202 through the cantilever 203, and the two sides of the wire clamp bracket 202 are fixedly connected to the wire clamp, which is connected to the wire clamp bracket 202 by bolts. The wire clamp is provided with a number of through holes for the wire pipe to pass through, so as to achieve the purpose of fixing the wire pipe.

[0027] Preferably, two cantilevers 203 are provided between the pillar 201 and the wire clamp bracket 202, and the two cantilevers 203 form a double cantilever structure, and a reinforcing support 204 is fixedly connected between the cantilever 203 and the pillar 201. The reinforcing support 204 and the double cantilever structure work together to greatly improve the supporting effect of the fixed wire-passing bracket 2. The fixed wire-passing bracket 2 plays the main role of supporting cables and wire tubes, and supports and fixes the middle part of the wire tube, greatly reducing the interference between cables. At the same time, it makes the cross-border fixing of cables on the train more beautiful.

[0028] The sliding rail type wire passing bracket includes a fixed base 305 installed on the top of the train, and a connecting column 304 is fixedly connected to the top of the fixed base 305, and a wire passing bracket cantilever is fixedly connected to one side of the connecting column 304. The wire passing bracket cantilever is fixedly connected with a sliding rail 303 arranged along the length direction of the wire passing bracket cantilever, and a slider is slidably connected to the sliding rail 303, and a sliding clamp 302 is fixedly connected to the slider; the sliding clamp 302 is provided with a plurality of through holes penetrating the sliding clamp 302, so as to achieve the purpose of fixing the wire tube.

[0029] See also Figure 7 Preferably, two slide rails 303 are provided at the bottom and top of the wire passing bracket cantilever, and each slide rail 303 is provided with a slider slidably connected to the sliding clamp 302, and the wire tube is fixedly inserted into the sliding clamp 302, thereby enabling the sliding clamp 302 to be better connected to the wire passing bracket cantilever, and providing better support for the wire tube, and will not cause damage to the sliding rail type wire passing bracket during frequent sliding.

[0030] See also Figure 7Preferably, a plurality of the sliders are fixedly connected to the sliding clamp plate 302 through a second connecting member, the second connecting member is an "O"-shaped metal connecting member, the slider is installed on the inner ring side of the "O"-shaped metal connecting member, and a sliding clamp plate 302 is provided on both sides of the outer side of the "O"-shaped metal connecting member. Thus, the sliding rail type wire passing bracket can fix more wire tubes, making the fixing of the wire tubes more integrated, standardized and beautiful.

[0031] Preferably, the front and rear ends of the slide rail 303 are provided with stops 301. When the slider slides to the stop 301 of the slide rail 303, it will be blocked and cannot continue to slide, thereby preventing the sliding clamp 302 on the cantilever of the wire crossing bracket from sliding out of the slide rail 303 in the event of vehicle abnormality or operating error.

[0032] See also Figure 1 and Figure 8 Preferably, the connecting column 304 on the slide rail type wire passing bracket is welded to any side surface of the fixed base 305 on the slide rail type wire passing bracket at 30 degrees. Specifically, when the slide rail type wire passing bracket is installed on the top of the train, the direction of the slide rail type wire passing bracket is biased toward the wire clamp plate, and this setting can ensure the natural transition of the bending of the wire tube. Whether the train is running smoothly or turning, the wire tube can be ensured to be within the appropriate bending limit.

[0033] See also Figure 1 and Figure 7 Preferably, the sliding rail type wire passing bracket protrudes 20 mm from the vehicle, and at the same time, the wire passing bracket cantilever of the sliding rail type wire passing bracket is tilted 20° relative to the horizontal plane, that is, the angle between the connecting column 304 is 110°. This setting can ensure that the wire pipe has a natural and smooth transition with the wire pipe on the fixed wire passing bracket 2 in the vertical direction.

[0034] In summary, see Figure 1 ,Pick Figure 1 Center line pipe section: first line pipe 01, second line pipe 02, third line pipe 03, fourth line pipe 04, fifth line pipe 05 and sixth line pipe 06. Under the gravity component force of each device and the line pipe tension, when the vehicle runs on a straight track: the second line pipe 02, the fourth line pipe 04, and the sixth line pipe 06 are in a straight state, the first line pipe 01, the third line pipe 03, and the fifth line pipe 05 are in a relaxed bending state, and the sliding clamp 302 in the sliding rail type wire passing bracket is located in the middle of the sliding rail 303, and the sliding clamp 302 has a front and rear sliding margin on the sliding rail 303, and the sliding margin is ±20mm.

[0035] When the vehicle runs on a curved track, the first wire tube 01 and the second wire tube 02 are in a stretched state. Under the tensile force of the wire tubes, the sliding clamp 302 in the sliding rail type wire-passing bracket slides upward along the sliding rail 303 until the force balance is reached; the third wire tube 03, the fourth wire tube 04, the fifth wire tube 05 and the sixth wire tube 06 are in a compressed state. Under the gravity component of each device and the pressure of the wire tubes, the sliding clamp 302 in the sliding rail type wire-passing bracket slides downward along the sliding rail 303 until the force balance is reached. The remaining wire tube sections maintain a small displacement. Through the action of the sliding rail type wire-passing bracket, the wire tube adapts to the length change caused by the vehicle turning. During the displacement of the wire tube, the wire tube winding friction phenomenon will not occur, thereby better ensuring the safe connection of the wire tube and the beautiful bending deformation.

[0036] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
