Description

Technical Field

[0001] The present invention belongs to the field of rail transit vehicle new construction and maintenance equipment installation, and in particular relates to a vehicle wire duct pre-assembly positioning device and a vehicle wire duct installation method. Background Art

[0002] During the installation of the central cable ducts of existing high-speed rail vehicles, the manufacturing errors of the car body crossbeam slides, car body mounting seats, and equipment mounting lugs lead to uncertainty in the exact connection dimensions between the cable ducts. During installation, the cable ducts must be positioned according to the actual conditions of the car body crossbeam slides and car body mounting seats. Before wiring the cable ducts, they must be pre-assembled and positioned on the car body.

[0003] The installation steps of the central cable duct of existing high-speed rail vehicles include the following steps:

[0004] (1) Transportation and pre-installation of cable ducts: Place the cable ducts on a special storage and transportation trolley and transport them to the installation position under the vehicle. Align the lifting ears of the cable ducts with the pre-embedded bolts of the vehicle body crossbeam slides and the eyelets of the vehicle body mounting base. Use nuts to pre-tighten the cable ducts, and then pre-tighten the entire vehicle cable duct from the first end to the second end.

[0005] (2) Adjustment and marking of cable troughs: After all cable troughs on one side are pre-tightened, the cable trough connection positions may not be aligned due to the error of the vehicle body crossbeam slide. In this case, the X-direction positioning of each cable trough needs to be adjusted through the oblong mounting holes on the cable trough lugs to ensure that the connections between the cable troughs can be penetrated by bolts for installation. After the adjustment is completed, the relative positions are marked at the cable trough connections.

[0006] (3) Disassembly of the cable trough: Remove the bolts at the connection between the cable troughs, remove the installation bolts at the cable trough ears, move the cable trough to the storage and transportation tooling, and transport it to the cable trough pre-assembly position, and place it in sequence from the first end to the second end according to the installation order of the existing vehicle.

[0007] (4) Wire duct connection and wiring: At the wire duct pre-assembly station, determine the relative positions of the wire ducts according to the marking records, and use bolts and nuts to pre-assemble the vehicle wire ducts together, and then carry out wiring after connection.

[0008] Therefore, when installing the cable ducts of current high-speed rail vehicles, the cable ducts need to be pre-assembled and positioned on the vehicle body, and the cable ducts are transported multiple times between the installation station and the pre-wiring station, resulting in low installation efficiency of the cable ducts.

[0083] Reference Figures 3 to 13 , the present invention discloses a vehicle cable duct pre-assembly positioning device.

[0084] The vehicle trunking pre-assembly positioning device includes a linearly extending positioning paving 2, extending in the X-direction. Multiple support stools 22 are spaced apart at the bottom of the positioning paving 2 along its extension direction. The tops of the support stools 22 are fixedly connected to the positioning paving 2. By installing the support stools 22 at the bottom of the positioning paving 2, the support stools 22 elevate the positioning paving 2, allowing it to match the height of the high-speed rail body.

[0085] The positioning paving member 2 comprises multiple sections of paving members 21 that are joined end to end, with adjacent paving members 21 being plugged in and secured. By configuring the positioning paving member 2 as a multi-section paving member 21, the positioning paving member 2 can be assembled on-site according to the desired cable trunking, ensuring that the length of the positioning paving member 2 matches the desired length of the cable trunking.

[0086] A first slide rail 3 and a second slide rail 4 are fixed to the positioning form 2. The first and second slide rails 3 and 4 can be connected to the positioning form 2 by welding or bolting. The first and second slide rails 3 and 4 extend along the X-direction. The first and second slide rails 3 and 4 are spaced apart along the Y-direction. The second slide rail 4 is taller than the first slide rail 3. A space for accommodating a wire trough is formed between the first and second slide rails 3 and 4.

[0087] In this embodiment, a plurality of first slidable positioning assemblies 5 are provided on the first slide rail 3. The first slidable positioning assemblies 5 are used to record the position of the eyelet of the vehicle body mounting seat. The plurality of first slidable positioning assemblies 5 are arranged along the extension direction of the first slide rail 3. The first slidable positioning assemblies 5 can be adjusted on the first slide rail 3 along the extension direction of the first slide rail 3.

[0088] The number of the first slidable positioning components 5 is determined according to the number of the lower hanging ears of the wire trough installed on the wire trough.

[0089] In this embodiment, a second slidable positioning assembly 6 is provided at each end of the second slide rail 4. The second slidable positioning assembly 6 can be adjusted on the second slide rail 4 along the extension direction of the second slide rail 4. The second slidable positioning assembly 6 is used to record the position of the body cross beam guide bolt in the longitudinal direction of the vehicle body and is connected to the body cross beam guide bolt to connect the positioning template 2 to the vehicle body.

[0090] The second rail 4 is also provided with a plurality of third slidable positioning assemblies 7, which are arranged along the extension direction of the second rail 4. Each third slidable positioning assembly 7 is located between two second slidable positioning assemblies 6. The third slidable positioning assembly 7 can be adjusted along the extension direction of the second rail 4. The third slidable positioning assembly 7 is used to record the position of the bolts in the vehicle body cross member guide slot.

[0091] The total number of the second slidable positioning components 6 and the third slidable positioning components 7 matches the number of the wire trough upper lugs on the wire trough.

[0092] Preferably, a second slidable positioning assembly 6 is provided at both ends of each backing member 21, and a third slidable positioning assembly 7 is located between the two second slidable positioning assemblies 6. By providing the second slidable positioning assemblies 6 at both ends of the backing member 21, when the second slidable positioning assemblies 6 are connected to the vehicle body, the connection between the backing member 21 and the vehicle body is more secure.

[0093] The number of the support members 21 is determined according to the length of the wire duct to be installed. The number of support members 21 used can be one or more.

[0094] In this embodiment, the first slidable positioning assembly 5 includes a first sliding base 51 slidably connected to the first slide rail 3. An upwardly extending vertical plate 52 is disposed on the top of the first sliding base 51 and is welded to the vertical plate 52. A sleeve 53 is disposed on the vertical plate 52, extending axially along the Y direction and relatively fixed to the vertical plate 52. A locking pin 54 is disposed within the inner hole of the sleeve 53. The locking pin 54 is longer than the sleeve 53, and its two ends extend through the sleeve 53, emerging from the ends.

[0095] The end of the lock pin 54 facing the second slide rail 4 is the head end of the lock pin 54, and the end of the lock pin 54 away from the second slide rail 4 is the tail end of the lock pin 54. A rear handle 541 having a cross-sectional area larger than that of the lock pin 54 is provided at the tail end of the lock pin 54. The rear handle 541 and the lock pin 54 are welded or integrally formed.

[0096] A first chute 31 is provided on the top surface of the first slide rail 3. The first chute 31 extends along the entire length of the first slide rail 3. On the left and right sidewalls of the first chute 31, there are first protrusions 32 extending from the center of the first chute 31. The first protrusions 32 are elongated and extend along the entire length of the first chute 31. The first protrusions 32 are integrally formed with the sidewalls of the first chute 31.

[0097] The bottom of the first sliding base 51 is provided with a plurality of first rollers 511 extending into the interior of the first slide groove 31, and the plurality of first rollers 511 are arranged along the extension direction of the first slide groove 31. The wheel diameter of the first roller 511 is smaller than the groove width of the first slide groove 31. The two adjacent first rollers 511 are staggered along the Y direction. The axial direction of the first roller 511 is vertically arranged. A first annular groove 5111 is provided on the outer wall surface of the first roller 511. When the first roller 511 extends into the interior of the first slide groove 31, the height of the first protrusion 32 is connected to the first annular groove 5111, and the first protrusion 32 extends into the interior of the first annular groove 5111 of the first roller 511.

[0098] One of the two adjacent first rollers 511 is connected to the first protrusion 32 on the left side of the first slide groove 31, and the other is connected to the first protrusion 32 on the right side of the first slide groove 31. By allowing the first protrusion 32 to extend into the first annular groove 5111 of the first roller 511, the Z direction of the first sliding base 51 is restricted, preventing the first sliding base 51 from separating from the first slide rail 3 in the Z direction.

[0099] In this embodiment, a first locking mechanism 55 is provided on the first sliding base 51 , and the first locking mechanism 55 is used to lock the relative position between the first sliding base 51 and the first slide rail 3 .

[0100] Specifically, a first mounting groove 512 is defined in the bottom surface of the first sliding base 51, extending along the Y direction. The first locking mechanism 55 includes a first locking block 551 slidably connected to the interior of the first mounting groove 512. The first locking block 551 moves along the direction of extension of the first mounting groove 512. The first locking block 551 abuts against two sidewalls of the first mounting groove 512 in the X direction. The bottom of the first locking block 551 extends below the bottom surface of the first sliding base 51.

[0101] When the first sliding base 51 is located on the first slide rail 3, the first mounting groove 512 is opposite to the first slide groove 31 of the first slide rail 3, and one end of the first mounting groove 512 extends to the outside of the first slide groove 31. When the first locking block 551 moves inside the first mounting groove 512, the first locking block 551 can abut against the side wall of the first slide groove 31.

[0102] The first locking mechanism 55 also includes a first locking bolt 552, the axial direction of which is arranged along the Y direction. The first locking bolt 552 is located on one side wall of the first sliding base 51 facing the Y direction. The first locking bolt 552 is rotatably connected to the first sliding base 51. The first locking bolt 552 extends into the interior of the first mounting groove 512 and passes through the first locking block 551 located therein. The first locking bolt 552 is threadedly connected to the first locking block 551. When the first locking bolt 552 is rotated, the first locking block 551 can move within the first mounting groove 512 along the Y direction. When the first locking block 551 abuts the side wall of the first slide groove 31, further rotation of the first locking bolt 552 causes the first locking block 551 to press against the side wall of the first slide groove 31, thereby locking the relative position between the first sliding base 51 and the first slide rail 3.

[0103] When using the first slidable positioning assembly 5 to record the eyelet position of a vehicle's body mounting seat, first release the first locking mechanism 55 to allow the first sliding base 51 to move on the first slide rail 3. The first sliding base 51 is then moved along the X-direction. When the locking pin 54 moves to a position nearly opposite the eyelet of the body mounting seat, the locking pin 54 is pulled toward its rear end. When the locking pin 54 moves to a position directly opposite the eyelet of the body mounting seat, the locking pin 54 is pushed toward the eyelet of the body mounting seat and inserted into the eyelet of the body mounting seat. Once the locking pin 54 is inserted into the eyelet of the body mounting seat, the first locking mechanism 55 locks the relative position between the first sliding base 51 and the first slide rail 3, completing the recording of the eyelet position of the body mounting seat.

[0104] In this embodiment, the second slidable positioning assembly 6 includes a second sliding base 61 slidably connected to the second slide rail 4. A third slide rail 62 is fixed to the top of the second sliding base 61, and the third slide rail 62 extends along the Y direction. A first frame 63 is slidably connected to the third slide rail 62 and is capable of moving along the extension direction of the third slide rail 62.

[0105] The first frame 63 includes a first sliding portion 631 slidably connected to the third slide rail 62. A first support portion 632 is provided above the first sliding portion 631. Multiple layers of first adjustment shims 633 are provided between the first support portion 632 and the first sliding portion 631. The first adjustment shims 633 are secured between the first support portion 632 and the first sliding portion 631 via bolts. The Z-axis height of the first support portion 632 can be adjusted by adjusting the number of first adjustment shims 633.

[0106] A first positioning post 6321 extending vertically upward is provided at the top of the first support portion 632. The first positioning post 6321 is welded or integrally formed with the first support portion 632. A vertical positioning eyelet 6322 is provided on the top end surface of the first support portion 632. The positioning eyelet 6322 and the first positioning post 6321 are arranged along the Y direction.

[0107] A second chute 41 is provided on the top surface of the second slide rail 4. The second chute 41 extends along the entire length of the second slide rail 4. On the sidewalls of the second chute 41, second protrusions 42 are provided, extending from the center of the second chute 41. The second protrusions 42 are elongated and extend along the entire length of the second chute 41. The second protrusions 42 are integrally formed with the sidewalls of the second chute 41.

[0108] The bottom of the second sliding base 61 is provided with a plurality of second rollers 611 extending into the interior of the second chute 41, and the plurality of second rollers 611 are arranged along the extension direction of the second chute 41. The wheel diameter of the second roller 611 is smaller than the groove width of the second chute 41. The two adjacent second rollers 611 are staggered along the Y direction. The axial direction of the second roller 611 is vertically arranged. A second annular groove 6111 is provided on the side wall surface of the second roller 611. When the second roller 611 extends into the interior of the second chute 41, the height at which the second protrusion 42 is located is connected to the second annular groove 6111, and the second protrusion 42 extends into the interior of the second annular groove 6111 of the second roller 611.

[0109] One of the two adjacent second rollers 611 is connected to the second protrusion 42 on the left side of the second slide groove 41, and the other second roller 611 is connected to the second protrusion 42 on the right side of the second slide groove 41. By allowing the second protrusion 42 to extend into the second annular groove 6111 of the second roller 611, the Z direction of the second sliding base 61 is restricted, preventing the second sliding base 61 from separating from the second slide rail 4 in the Z direction.

[0110] In this embodiment, a second locking mechanism 64 is provided on the second sliding base 61 , and the second locking mechanism 64 is used to lock the relative position between the second sliding base 61 and the second slide rail 4 .

[0111] Specifically, a second mounting groove 612 is defined on the bottom surface of the second sliding base 61. The second mounting groove 612 extends along the Y direction. The second locking mechanism 64 includes a second locking block 641 slidably connected to the interior of the second mounting groove 612. The second locking block 641 moves along the direction of extension of the second mounting groove 612. The second locking block 641 abuts against two sidewalls of the second mounting groove 612 in the X direction. The bottom of the second locking block 641 extends below the bottom surface of the second sliding base 61.

[0112] When the second sliding base 61 is located on the second slide rail 4, the second mounting groove 612 is opposite to the second slide groove 41 of the second slide rail 4, and one end of the second mounting groove 612 extends to the outside of the second slide groove 41. When the second locking block 641 moves inside the second mounting groove 612, the second locking block 641 can abut against the side wall of the second slide groove 41.

[0113] The second locking mechanism 64 also includes a second locking bolt 642, the axial direction of which is arranged along the Y direction. The second locking bolt 642 is located on one side wall of the second sliding base 61 facing the Y direction. The second locking bolt 642 is rotatably connected to the second sliding base 61. The second locking bolt 642 extends into the interior of the second mounting groove 612 and passes through the second locking block 641 located therein. The second locking bolt 642 is threadedly connected to the second locking block 641. When the second locking bolt 642 is rotated, the second locking block 641 can move within the second mounting groove 612 along the Y direction. When the second locking block 641 abuts the side wall of the second slide groove 41, further rotation of the second locking bolt 642 causes the second locking block 641 to press against the side wall of the second slide groove 41, thereby locking the relative position between the second sliding base 61 and the second slide rail 4.

[0114] When using the second slidable positioning assembly 6 to record the eyelet position of the vehicle's body mounting seat, first release the second locking mechanism 64 to allow the second sliding base 61 to move on the second slide rail 4. The second sliding base 61 is then moved along the X-direction. When the positioning eyelet 6322 is aligned with the body crossbeam chute bolts reserved in the body crossbeam chute, the body crossbeam chute bolts are inserted into the positioning eyelet 6322 and connected to the body crossbeam chute bolts passing through the positioning eyelet 6322 using a nut, thereby securing the second slidable positioning assembly 6 relative to the vehicle. Once the second slidable positioning assembly 6 is secured relative to the vehicle, the second locking mechanism 64 locks the relative position between the second sliding base 61 and the second slide rail 4, completing the recording of the eyelet position of the vehicle mounting seat.

[0115] In this embodiment, the third slidable positioning assembly 7 includes a third sliding base 71 slidably connected to the second slide rail 4. A fourth slide rail 72 is fixed to the top of the third sliding base 71, and the fourth slide rail 72 extends along the Y direction. A second frame 73 is slidably connected to the fourth slide rail 72, and the second frame 73 is capable of moving along the extension direction of the fourth slide rail 72.

[0116] Specifically, the second frame 73 includes a second sliding portion 731 slidably connected to the fourth slide rail 72. A second support portion 732 is provided above the second sliding portion 731. Multiple layers of second adjustment shims 733 are provided between the second support portion 732 and the second sliding portion 731. The second adjustment shims 733 are secured between the second support portion 732 and the second sliding portion 731 via bolts. The Z-axis height of the second support portion 732 can be adjusted by adjusting the number of second adjustment shims 733.

[0117] A second positioning post 7321 extending vertically upward is provided at the top of the second support portion 732. The second positioning post 7321 is welded or integrally formed with the second support portion 732. A positioning notch 7322 is provided on the top end surface of the second support portion 732, with the opening of the positioning notch 7322 facing the X direction. The positioning notch 7322 and the second positioning post 7321 are arranged along the Y direction.

[0118] The bottom of the third sliding base 71 is provided with a plurality of third rollers 711 extending into the interior of the second slide groove 41, and the plurality of third rollers 711 are arranged along the extension direction of the second slide groove 41. The wheel diameter of the third roller 711 is smaller than the groove width of the second slide groove 41. The two adjacent third rollers 711 are staggered along the Y direction. The axial direction of the third roller 711 is vertically arranged. A third annular groove 7111 is provided on the side wall surface of the third roller 711. When the third roller 711 extends into the interior of the second slide groove 41, the height at which the second protrusion 42 is located is connected to the third annular groove 7111, and the second protrusion 42 extends into the interior of the third annular groove 7111 of the third roller 711.

[0119] One of the two adjacent third rollers 711 is connected to the second protrusion 42 on the left side of the second slide groove 41, and the other is connected to the second protrusion 42 on the right side of the second slide groove 41. By allowing the second protrusion 42 to extend into the third annular groove 7111 of the third roller 711, the Z direction of the third sliding base 71 is restricted, preventing the third sliding base 71 from separating from the second slide rail 4 in the Z direction.

[0120] In this embodiment, a third locking mechanism 74 is provided on the third sliding base 71 , and the third locking mechanism 74 is used to lock the relative position between the third sliding base 71 and the second slide rail 4 .

[0121] Specifically, a third mounting groove 712 is defined on the bottom surface of the third sliding base 71, extending along the Y-direction. The third locking mechanism 74 includes a third locking block 741 slidably connected within the third mounting groove 712. The third locking block 741 moves along the direction of extension of the third mounting groove 712. The third locking block 741 abuts against two sidewalls of the third mounting groove 712 in the X-direction. The bottom of the third locking block 741 extends below the bottom surface of the third sliding base 71.

[0122] When the third sliding base 71 is located on the second slide rail 4, the third mounting groove 712 is opposite to the second slide groove 41 of the second slide rail 4, and one end of the third mounting groove 712 extends to the outside of the second slide groove 41. When the third locking block 741 moves inside the third mounting groove 712, the third locking block 741 can abut against the side wall of the second slide groove 41.

[0123] The third locking mechanism 74 also includes a third locking bolt 742, the axial direction of which is arranged along the Y direction. The third locking bolt 742 is located on one side wall of the third sliding base 71 facing the Y direction. The third locking bolt 742 is rotatably connected to the third sliding base 71. The third locking bolt 742 extends into the interior of the third mounting groove 712 and passes through the third locking block 741 located therein. The third locking bolt 742 is threadedly connected to the third locking block 741. When the third locking bolt 742 is rotated, the third locking block 741 can move within the third mounting groove 712 along the Y direction. When the third locking block 741 abuts the side wall of the second slide groove 41, further rotation of the third locking bolt 742 causes the third locking block 741 to press against the side wall of the second slide groove 41, thereby locking the relative position between the third sliding base 71 and the second slide rail 4.

[0124] When using the third slidable positioning assembly 7 to record the eyelet position of the vehicle's body mounting seat, first release the third locking mechanism 74 to allow the third sliding base 71 to move on the second slide rail 4. The third sliding base 71 is then moved along the X-direction. When the positioning notch 7322 aligns with the body crossbeam chute bolts reserved in the body crossbeam chute, the body crossbeam chute bolts enter the positioning notch 7322. Once the body crossbeam chute bolts enter the positioning notch 7322, the third locking mechanism 74 locks the relative position between the third sliding base 71 and the second slide rail 4, completing the recording of the eyelet position of the vehicle body mounting seat.

[0125] The present invention discloses a vehicle cable duct installation method, which adopts the vehicle cable duct preassembly positioning device disclosed in the present invention and includes the following steps:

[0126] Transport the positioning template to the wire duct installation station, use the positioning template 2 to position it on the vehicle body, and use the first slidable positioning component 5 to record the position of the eyelet of the vehicle body mounting seat along the X direction; use the second slidable positioning component 6 and the third slidable positioning component 7 to record the position of the vehicle body crossbeam slide bolt along the X direction.

[0127] After the eyelet hole position of the vehicle body mounting seat along the X direction and the vehicle body cross beam sliding groove bolt position along the X direction are recorded, the positioning template 2 is transported to the pre-assembly platform, and the wire slot can be pre-assembled on the pre-assembly platform according to the vehicle body positioning size recorded by the positioning template.

[0128] When recording the eyelet hole position of the vehicle body mounting seat along the X direction:

[0129] The first slidable positioning assembly 5 is controlled to move along the X direction, and the first slidable positioning assembly 5 is opposite to the eyelet hole of the vehicle body mounting seat one by one, the relative position between the first slidable positioning assembly 5 and the positioning template 2 is locked, and the position of the eyelet hole of the vehicle body mounting seat is recorded.

[0130] Specifically, when the first slidable positioning assembly 5 is opposite to the eyelet hole of the vehicle body mounting seat, the first locking mechanism 55 is first loosened, so that the first sliding base 51 can move on the first sliding rail 3. The first sliding base 51 is moved along the X direction, when the locking pin 54 moves to be opposite to the eyelet hole of the vehicle body mounting seat, the locking pin 54 is pulled to move to the rear end direction of the locking pin 54, when the locking pin 54 moves to be opposite to the eyelet hole of the vehicle body mounting seat, the locking pin 54 is pushed to move to the direction of the eyelet hole of the vehicle body mounting seat, and the locking pin 54 is inserted into the eyelet hole of the vehicle body mounting seat. After the locking pin 54 is inserted into the eyelet hole of the vehicle body mounting seat, the relative position between the first sliding base 51 and the first sliding rail 3 is locked by the first locking mechanism 55, that is, the position recording of the vehicle body mounting seat is completed.

[0131] When recording the vehicle wire slot cross beam sliding groove bolt position along the X direction:

[0132] Firstly, the second slidable positioning assembly 6 is controlled to move along the X direction, so that the second slidable positioning assembly 6 is opposite to the vehicle body cross beam sliding groove bolt, and the second slidable positioning assembly 6 is fixed with the vehicle body cross beam sliding groove bolt, and the relative position between the second slidable positioning assembly 6 and the positioning template is fixed.

[0133] After the second slidable positioning assembly 6 is fixed with the vehicle body cross beam sliding groove bolt, the third slidable positioning assembly 7 is controlled to move along the X direction, so that the third slidable positioning assembly 7 is opposite to the remaining vehicle body cross beam sliding groove bolt, and the relative position between the third slidable positioning assembly 7 and the positioning template is fixed.

[0134] Specifically, when using the second slidable positioning assembly 6 to record the position of the vehicle's crossbeam runner bolt, the second locking mechanism 64 is first released, allowing the second sliding base 61 to move on the second slide rail 4. The second sliding base 61 is then moved along the X-direction. When the positioning eyelet 6322 is aligned with the crossbeam runner bolt pre-set within the crossbeam runner, the crossbeam runner bolt is inserted into the positioning eyelet 6322 and a nut is used to connect the crossbeam runner bolt through the positioning eyelet 6322, thereby securing the second slidable positioning assembly 6 relative to the vehicle body. Finally, the second locking mechanism 64 is used to lock the relative position between the second sliding base 61 and the second slide rail 4, thereby completing the recording of the position of the crossbeam runner bolt and its longitudinal position in the vehicle body.

[0135] When using the third slidable positioning assembly 7 to record the position of the vehicle's cross-beam runner bolt, first release the third locking mechanism 74, allowing the third sliding base 71 to move on the second slide rail 4. The third sliding base 71 is then moved in the X direction. When the positioning notch 7322 aligns with the cross-beam runner bolt pre-set within the cross-beam runner, the cross-beam runner bolt is positioned within the positioning notch 7322. Once the cross-beam runner bolt is within the positioning notch 7322, the third locking mechanism 74 locks the relative position between the third sliding base 71 and the second slide rail 4, completing the recording of the cross-beam runner position.
