Description

Technical Field

[0001] This utility model relates to the field of rail transit locomotive pipeline layout, and in particular to an integrated locomotive pipeline fixing device. Background Technology

[0002] In existing technologies, locomotive pipeline layout typically adopts a design based on two-dimensional or three-dimensional software combined with on-site assembly of each pipeline on the train. Designers use simulation software to simulate the pipeline bending and assembly process (e.g., CNC pipe bending machine simulation trial bending) and rely on fasteners such as pipe joints and pipe clamps to distribute the pipelines in areas such as the roof and machine room. While this technical solution can achieve basic functions, it has significant drawbacks: First, the design phase does not adequately consider the process constraints of the production site. For example, the compatibility between the straight section length of the steel pipe and the main clamping mold of the pipe bending machine is not strictly verified, leading to mold interference or ground collisions during actual bending, forcing rework and exacerbating the confusion in pipeline routing. Second, the loose layout of pipelines lacks standardized path planning. When hydraulic pipelines and cables are intersected, no layered channels are reserved, causing welding joints, pipe clamps, and other components to occupy space. This not only increases the difficulty of assembly (requiring disassembly of the cover plate and repeated threading) but also causes welding quality defects or pipe joint pre-assembly failures due to excessively short straight sections at the pipe ends. In addition, on-site assembly relies on manual experience to adjust the pipeline routing, which easily leads to problems such as deviations in pipeline bending angles and cable twisting, resulting in more air leakage points (such as loose pipe clamps or seal failure) and circuit faults caused by electromagnetic interference. While some improvement solutions attempt to reduce interference through integrated cable tray classification (such as partitioning auxiliary / control / signal cables) or optimizing traction motor paths, they remain constrained by traditional design frameworks and cannot systematically address issues such as high redundancy in pipeline layout and the need for large-scale disassembly of cover plates during maintenance, severely limiting locomotive safety and operational efficiency. Therefore, a pipeline layout method that enables pre-integration of pipelines, hierarchical path optimization, and adaptation to production process constraints is urgently needed.

[0033] Example 1

[0034] like Figures 1 to 11 As shown, this utility model provides a technical solution:

[0035] An integrated locomotive pipeline fixing device includes, but is not limited to, a connection unit 1 for carrying pipelines and lines, and a connector 2 for fixing the connection unit 1. A grounding wire is provided between adjacent connection units 1. A connection hole 9 that cooperates with the steel structure 3 of the vehicle frame is also provided on the connection unit 1. A pipeline mounting rail 4 and a cable mounting plate 5 are provided on the connection unit 1.

[0036] Based on the above structure, this solution uses connector 2 to fix multiple connecting units 1 as a whole. Connecting holes 9 are provided on the connecting units 1, and the connecting holes 9 cooperate with the steel structure of the frame 3, making the entire assembly process more efficient. At the same time, the connecting pipe mounting rail 4 and cable mounting plate 5 can fix the pipes and lines on the locomotive, realizing the modular assembly of pipes and cables, improving the aesthetics of pipe and cable laying, and separating the assembly, debugging and on-site installation of pipelines, thus improving construction efficiency and installation quality.

[0037] As an example, the connection unit 1 may include a U-shaped mounting bracket 11, a wire threading process hole 12, and a pipe threading process hole 13; the wire threading process hole 12 and the pipe threading process hole 13 are provided in multiple ways along the length of the U-shaped mounting bracket 11, and the U-shaped mounting bracket 11 is also provided with a lifting plate 14.

[0038] Based on the above structure, the entire connection unit 1 can be hoisted and transported by the hoisting plate 14, which facilitates the transportation of the overall structure. The wire threading process hole 12 can be conveniently connected to external cables; the conduit threading process hole 13 can be conveniently connected to external pipelines.

[0039] As an example, the U-shaped mounting bracket 11 may include a supporting base plate 111 and a supporting side plate 112; the supporting side plate 112 is arranged perpendicular to the supporting base plate 111, and the lifting plates 14 are respectively provided on the supporting side wall at the ends away from the supporting base plate 111; the wire threading process hole 12 and the pipe threading process hole 13 are both provided on the supporting base plate 111; the lifting plate 14 is also provided with a lifting hole 141.

[0040] As an example, the wire threading process hole 12 is an oblong hole, which is set vertically to the support side wall, and the tube threading process hole 13 is a rectangular hole, which is set at intervals between adjacent wire threading process holes 12.

[0041] Based on the above structure, the oblong hole facilitates the passage of the line, and the rectangular hole facilitates the passage of the pipe; the lifting hole 141 facilitates hoisting.

[0042] As an example, the connector 2 can be a U-shaped plate, which is adapted to the outer contour of the U-shaped mounting bracket 11. The U-shaped plate can cover the first side plate 21, the second side plate 22 and the connecting base plate 23.

[0043] The first locking hole 24 and the second locking hole 25 are not collinear when projected onto the same vertical plane.

[0044] Based on the above structure, by providing a first locking hole 24 and a second locking hole 25 on the first side plate 21 and the second side plate 22, it can be connected to the U-shaped mounting brackets 11 on both sides respectively, and locked with bolts to make it an integral structure.

[0045] As an example, the connecting holes 9 are set on the support base plate 111, and multiple connecting holes 9 are set in the same vertical plane; by connecting the connecting unit 1 to the frame steel structure 3 through multiple connecting holes 9, the connection can be made more stable.

[0046] As an example, the connecting hole 9 can be a strip-shaped mounting hole, which has a large adjustment margin and is easy to install.

[0047] As an example, grounding bolts 6 can be provided between adjacent U-shaped mounting brackets 11, and grounding wires 7 can be provided between the grounding bolts 6; at least one external grounding wire 8 is provided on the overall structure connecting multiple connection units 1.

[0049] As an example, the pipe mounting rail 4 and the cable mounting plate 5 are arranged on the support base plate 111, and multiple pipe mounting rails 4 and cable mounting plates 5 are staggered along the length of the support base plate 111.

[0050] The installation method of this scheme is as follows: First, weld the U-shaped mounting bracket 11, the pipeline mounting rail 4, and the cable mounting plate 5 bracket into a single component. Then, assemble the three-section connecting unit 1 into a whole by bolting. After the component is assembled, lay the pipes and cables. First, fix the brake pipeline to the pipeline mounting rail 4 with pipe clamps. After the pipeline is assembled, lay the cables. After the pipes and cables are laid, lift the fixing device as a whole and place it on the vehicle body at the pre-designed position. Then, connect and fix it to the vehicle body with bolts.

[0051] Each connection unit 1 consists of a U-shaped mounting bracket 11, a conduit mounting rail 4, and a cable mounting plate 5, and is divided into upper and lower layers. The lower layer has a conduit mounting rail 4 for conduit laying, and the upper layer has a cable mounting plate for wiring.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
