[0001] This utility model belongs to the field of high-speed train driver's cab component assembly, specifically relating to a ground pre-assembly device for high-speed train driver's cab wiring harness. Background Technology

[0002] The cab wiring process is an integral part of the standard EMU manufacturing process, and its accuracy and rationality directly affect the EMU's functionality and product quality. Currently, however, the cab wiring process must be carried out inside the cab, which is cramped, potentially posing safety and quality risks. Furthermore, the hot summer months reduce work efficiency.

[0003] Currently, the main wiring harnesses under the vehicle and in the passenger compartment are pre-assembled before being installed on the vehicle. However, the inventors have discovered that the pre-assembly table of the main wiring harness pre-assembly device for the main wiring harness under the vehicle and in the passenger compartment is a single rectangular or strip structure, which is only suitable for the pre-assembly of the main wiring harness and its branch wiring harnesses in the passenger compartment and under the vehicle. In contrast, the wiring structure in the driver's cab is three-dimensional and the wiring harnesses are crisscrossed. Therefore, the existing pre-assembly device for the main wiring harness under the vehicle and in the passenger compartment cannot be used for the pre-assembly of the wiring harness in the driver's cab. Utility Model Content

[0004] To address the technical problem that the pre-assembly platform of the existing undercarriage and passenger compartment main wiring harness pre-assembly device cannot adapt to the ground pre-assembly of the driver's cab wiring harness, this utility model discloses a ground pre-assembly device for the wiring harness in the driver's cab of a high-speed train. This device is used for the pre-assembly of the wiring harness in the driver's cab, realizing the forward shift of the wiring process, reducing the wiring time in the confined space of the driver's cab, and effectively improving the wiring efficiency in the driver's cab.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A ground pre-assembly device for wiring harnesses in a high-speed train driver's cab includes a wiring harness pre-assembly platform, a workbench, and a branching bracket. The wiring harness pre-assembly platform includes a first support platform, a second support platform, and a wire trough. The first support platform is arranged along the X direction, and the second support platform is arranged along the Y direction. The first support platform and the second support platform are connected together to form a U-shape. The wire trough is in the shape of a grid, and the wire trough and the branching bracket are arranged on the first support platform and the second support platform. The workbench is located outside the wiring harness pre-assembly platform.

[0007] As a further technical solution, the first support platform includes four supports and the second support platform includes two supports. The tabletops of the two first support platforms are connected to one end of the tabletop of the second support platform, and the tabletops of the other two first support platforms are connected to the other end of the tabletop of the second support platform. The tabletops of the two second support platforms are arranged side by side and parallel to each other. The four first support platforms and the two second support platforms are connected together to form a U-shape.

[0008] As a further technical solution, the first support platform and the second support platform are detachably connected by connectors.

[0009] As a further technical solution, the cable tray, the branch bracket, and the first support platform and the second support platform are detachably connected.

[0010] As a further technical solution, a long strip-shaped groove and a protrusion are provided on the surface of the first support platform along the X direction; a long strip-shaped groove and a protrusion are provided on the surface of the second support platform along the Y direction.

[0015] The beneficial effects of this utility model are as follows:

[0016] Based on the configuration of the wiring harness in the driver's cab of a high-speed train, this utility model extracts and simplifies the design of the wiring troughs on the driver's cab floor, the wiring racks on the side walls, and the control panel, forming the main structure of the device. Specifically, the first support platform is set along the X direction, and the second support platform is set along the Y direction.

[0027] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this utility model proposes a ground pre-assembly device for the wiring harness of a high-speed train driver's cab.

[0028] In a typical embodiment of this utility model, such as Figure 1 As shown, the ground pre-assembly device for the wiring harness in the driver's cab of a high-speed train disclosed in this embodiment includes a wiring harness pre-assembly platform 1, a workbench 2, and a wire distribution bracket 3. The wiring harness pre-assembly platform 1 includes a first support platform 12, a second support platform 13, and a wire trough 11. The first support platform 12 is arranged along the X direction; the second support platform 13 is arranged along the Y direction, and the two form a perpendicular relationship. The first support platform 12 and the second support platform 13 are connected together to form a U-shape. The wire trough 11 is in the shape of a well, and the wire trough 11 is arranged on the first support platform 12 and the second support platform 13. The wire distribution bracket 3 is also arranged on the first support platform 12 and the second support platform 13. The workbench 2 is arranged on the outside of the wiring harness pre-assembly platform. Based on the configuration of the wiring harness in the EMU driver's cab, this embodiment extracts and simplifies the design of the wiring troughs on the driver's cab floor, the wiring racks on the side walls, and the control panel to form the main structure of the device. Specifically, the first support platform 12 is set along the X direction, the second support platform is set along the Y direction, and the first support platform 12 and the second support platform 13 are connected together to form a "U" shape. At the same time, the wiring trough is designed as a "well" shape and is set on the first support platform 12 and the second support platform 13. This realizes the forward shift of the wiring process, reduces the wiring time in the narrow space of the driver's cab, and effectively improves the wiring efficiency of the driver's cab.

[0029] Furthermore, in this embodiment, the first support platform 12 has elongated grooves and protrusions along the X direction on its surface; the second support platform 13 has elongated grooves and protrusions along the Y direction on its surface. The cable divider 3 and the cable groove 11 are placed on the corresponding protrusions, and the connectors of the cable divider 3, the cable groove 11, and the first support platform 12 and the second support platform 13 pass through the corresponding grooves to fix them. Furthermore, the surfaces of the first support platform 12 and the second support platform 13 adopt existing profile structures.

[0030] In this embodiment, the platform of the first support platform 12 is a long rectangular platform, and the platform is supported by spaced-apart support legs. There are four first support platforms 12. The platform of the second support platform 13 is also a long rectangular platform, and the platform is supported by spaced-apart support legs. There are two second support platforms 13. The platforms of two first support platforms 12 are connected to one end of the platform of the second support platform 13, and the platforms of the other two first support platforms 12 are connected to the other end of the platform of the second support platform 13. The platforms of the two second support platforms 13 are arranged side by side and parallel to each other. The four first support platforms 12 and the two second support platforms 13 are connected together to form a "U" shape.

[0031] It should be noted that the connection between the first support platform 12 and the second support platform 13 is detachable, and can be connected in different shapes according to the assembly form of the wire harness to better support the wire trough 11. Specifically, the connection between the first support platform 12 and the second support platform 13 is achieved through a right-angled triangular connector. The right-angled triangular connector is located at the right angle formed by the first support platform 12 and the second support platform 13. Connection holes are provided on the side of the table surface of the right-angled triangular connector, the first support platform 12, and the second support platform 13. Screws are connected to the table surface of the first support platform 12 and the second support platform 13 through the connection holes, thereby achieving a detachable connection between the table surfaces of the first support platform 12 and the second support platform 13.

[0032] In this embodiment, the cable tray 11, the branch bracket 3, the first support platform 12, and the second support platform 13 are detachably connected. The cable tray 11 in this embodiment is shaped like a "well". The wiring harness pre-assembly platform 1 in this embodiment is built to a 1:1 scale with reference to the driver's cab structure. This platform differs from existing pre-assembly schemes for wiring harnesses in passenger compartments and under the vehicle. This embodiment, referencing the driver's cab structure, designs the cable tray 11 in a "well" shape, suitable for pre-assembly of wiring in the driver's cab. This allows the wiring process in the driver's cab to be moved forward, avoiding work in confined spaces. The device can be placed in a spacious area on the ground, and the operating height is ergonomically designed, greatly improving the working conditions for wiring operators and effectively increasing construction efficiency. The cable tray 11 in this embodiment is formed integrally using a bending process.

[0033] In this embodiment, three workbenches 2 are provided, located on the left, right, and front sides of the support platform, respectively. The workbench surface 21 of the workbench 2 is designed to be foldable, as shown in the following figure. Figure 2 As shown, in this embodiment, the tabletops 21 of the left and right workbenches 2 are designed as foldable tabletops 21, while the front tabletop 21 is designed as a non-foldable tabletop 21. The foldable tabletops 21 adopt an unfoldable structure. In the folded state, they are used for storing wiring branch cables, saving floor space. In the unfolded state, they can meet the requirements for connector pre-assembly, further improving the wiring pre-assembly rate. Specifically, the workbench 2 includes a foldable tabletop 21, and rollers 22 are provided at the bottom of the workbench 2. The position of the workbench 2 can be adjusted by providing the rollers 22. The rollers 22 can be existing casters or self-driving rollers with drive, etc., whichever is required. The foldable tabletop 21 includes at least two tabletops 21 connected by hinges to achieve its folding.

[0034] Furthermore, the splitter bracket 3 in this embodiment includes a base plate 31, on which multiple splitter rods 32 are provided, and a connection hole is also provided on the base plate 31. The base plate 31 is detachably connected to the first support platform 12 or the second support platform 13 through the connection hole. The multiple splitter rods 32 are arranged side by side to separate the wire harnesses and prevent different wire harnesses from getting tangled together. The detachable connection between the base plate 31 and the first support platform 12 or the second support platform 13 through the connection hole can adjust the position of the splitter bracket 3 at any time according to the position of the wire harnesses.

[0035] Furthermore, in this embodiment, a ruler and an adjustable wiring bracket 3 are also provided at the corresponding positions in the on-vehicle wiring area (the sides of the first support platform and the second support platform). Operators can freely adjust the wiring position according to the position of the on-vehicle equipment and the ruler to improve wiring accuracy.

[0036] Furthermore, the main cable tray 11 structure in this embodiment adopts a detachable and adjustable design, which is suitable for different vehicle driver's cab structures and meets the needs of subsequent mass-produced vehicle upgrades.

[0037] Furthermore, this embodiment constructs a 1:1 scale model of the main wiring path in the EMU driver's cab. The wiring paths of the driver's cab floor cable trays 11, side wall cable racks, and control panel are extracted and simplified to form the main structure of the device. Operators complete the wiring installation at the corresponding locations along the path. The support structure of this device is ergonomically designed, allowing operators to complete wiring installation while standing normally. The surrounding split-type workbench 2 is equipped with lockable anti-slip wheels for easy placement or adjustment when not in use. The main frame of this device adopts a sliding groove structure and is equipped with adjustable cable racks, allowing operators to freely adjust the cable rack position for cable distribution and fixing according to the location of the equipment on the train.

[0038] This device is placed in a spacious area on the ground. Operators can perform wiring distribution, bundling, and connector pre-assembly of the cab wiring harness. After completion, the entire cab wiring harness can be hoisted onto the vehicle, effectively reducing the wiring time inside the cab and improving construction efficiency.

[0039] Finally, it should be noted that relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
