Description

Technical Field

[0001] This application relates to the field of rail transit technology, and in particular to a welding fixture for fixing transfer boxes. Background Technology

[0002] During the operation of high-speed trains and urban rail vehicles, the waste generated by the toilet system typically first passes through a vacuum toilet pulverizer to break down feces, toilet paper, and other solid debris into fine particles. Then, relying on vacuum or pressure difference, it is discharged into a transfer tank, and subsequently into a sewage tank for collection. The transfer tank is constructed from multiple irregularly shaped components, including a tank body, inlet pipe, outlet pipe, flanges, and various mounting plates.

[0003] In related technologies, the transfer box is manually installed on a rail vehicle. The specific steps are as follows: first, align the positions of the transfer box's inlet and outlet pipes with the tank body; then, perform a trial installation of the tank body and the rail vehicle; after repeatedly adjusting the angle and gap, weld the tank body of the transfer box onto the rail vehicle; weld the flange plate of the transfer box to the flange of the rail vehicle; connect the transfer box's inlet pipe to the vacuum toilet pulverizer; and connect the transfer box's outlet pipe to the sewage tank.

[0004] However, the manual installation of the transfer box in the relevant technology can lead to a large cumulative positioning error, making it difficult to connect the pipeline with the rail vehicle. In addition, manual positioning is time-consuming, resulting in low operation efficiency. Utility Model Content

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0035] The existing transfer container is welded to the rail vehicle. The transfer container consists of several irregularly shaped components, including a tank body, a drain pipe, an inlet pipe, a flange, and a mounting plate. Waste is discharged into the tank body through the inlet pipe using vacuum or pressure difference. The waste in the tank body is then discharged into a wastewater tank for collection through the drain pipe. The transfer container requires manual assembly before being connected to the rail vehicle. This manual assembly leads to significant accumulated positioning errors, making it difficult to align the inlet and outlet pipes and causing problems with pipe connection to the rail vehicle.

[0036] Furthermore, during the trial assembly of the transfer box and the rail vehicle, the angle and gap were adjusted manually multiple times before the transfer box was welded onto the rail vehicle. This process resulted in a long time consumption for manual positioning, leading to low work efficiency.

[0037] In view of this, this application provides a welding tool for fixing the transfer box, in order to solve the problems in the prior art where manual installation of the transfer box results in large cumulative positioning errors, making subsequent pipeline docking with the rail vehicle difficult, and manual positioning is time-consuming, leading to low work efficiency.

[0038] The welding fixture for fixing the transfer box provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0039] like Figure 1 and Figure 2 As shown, the welding fixture for fixing the transfer box in this embodiment includes a base plate 100, a pipeline positioning component 200, a flange plate positioning component 300, and a mounting plate positioning component 400.

[0040] The bottom plate 100 is used to support the tank of the transfer container.

[0041] Pipe positioning component 200, the lower end of which is connected to the base plate 100, is used to fix the pipeline of the transfer box.

[0042] Flange plate positioning component 300, the lower end of which is connected to the base plate 100, is used to fix the flange plate of the transfer box.

[0043] Mounting plate positioning component 400, the lower end of which is connected to the base plate 100, is used to fix the mounting plate of the transfer box.

[0044] In the above structure, the tank body of the transfer container is placed on the base plate 100, which provides air-guided support for the tank body. The lower end of the pipeline positioning component 200 is connected to the base plate 100, and the pipeline positioning component 200 can fix the inlet and outlet pipes of the transfer container. The lower end of the flange plate positioning component 300 is connected to the base plate 100, and the flange plate positioning component 300 can position and fix the flange plate of the transfer container. The lower end of the mounting plate positioning component 400 is connected to the base plate 100, and the mounting plate positioning component 400 is fixed to the mounting plate of the transfer container, thereby achieving a positioning function.

[0045] When the tank of the transfer box is placed on the base plate 100, the base plate 100 serves to support and position the tank, ensuring that the tank can be placed stably on the base plate 100. The sewage inlet pipe and sewage outlet pipe of the transfer box are positioned by the pipe positioning component 200 to ensure that the sewage inlet pipe and sewage outlet pipe are fixed. The flange plate of the transfer box is connected to the flange plate positioning component 300 after being positioned. The mounting plate of the transfer box is connected to the mounting plate positioning component 400 after being positioned, ensuring that the entire transfer box is assembled on the welding fixture.

[0046] Specifically, the base plate 100 serves as a reference plane, and the transfer box uses the base plate 100 as a positioning reference. This eliminates the cumulative error caused by the positioning reference, improves the overall assembly accuracy, and the base plate 100 supports the tank body of the transfer box, providing a stable load-bearing platform. This ensures that the tank body will not tilt or shake due to uneven force during storage and transportation, guaranteeing the stability of the overall structure of the transfer box. The pipe positioning component 200, flange plate positioning component 300, and mounting plate positioning component 400 are connected to the base plate 100 respectively, thereby positioning and fixing the components of the transfer box. The pipe positioning component 200 fixes the pipes, effectively preventing pipe detachment. The flange plate positioning component 300 ensures the stability of the connection with the flange plate, and the mounting plate positioning component 400 fixes the mounting plate, ensuring stable installation of the entire device and preventing shaking. This eliminates the need for repeated measurements using the welding fixture of this application, reducing the time spent on secondary handling and repeated adjustments, and improving work efficiency.

[0047] like Figure 1 and Figure 3 As shown, in some embodiments, the pipeline positioning component 200 includes a fixing plate 210 and a limiting component 220. The lower end of the fixing plate 210 is connected to the base plate 100, and the limiting component 220 is disposed on the fixing plate 210. The limiting component 220 is used to fix or release the pipeline of the transfer box.

[0048] In this application, the lower end of the fixing plate 210 is fixedly connected to the base plate 100, and the limiting member 220 is provided on the fixing plate 210. The limiting member 220 can fix the pipeline of the transfer box. When the pipeline of the transfer box needs to be disassembled from the pipeline positioning member 200, the limiting member 220 only needs to be unlocked, thereby releasing the locking of the pipeline of the transfer box.

[0049] Specifically, through the coordinated action of the fixing plate 210 and the limiting member 220, the pipeline of the transfer box can be fixed while ensuring that the pipeline of the transfer box can be connected to the inlet of the sewage tank. The limiting member 220 is set on the fixing plate 210 and is used to fix or release the pipeline of the transfer box. When it is necessary to fix the pipeline, the limiting member 220 locks the pipeline to prevent the pipeline from shaking, which would affect the assembly accuracy and increase the cumulative error. When it is necessary to disassemble the pipeline, the limiting member 220 can release the fixation, which simplifies the operation process and reduces labor and time costs.

[0050] like Figure 3As shown, in some embodiments, the limiting member 220 includes a first limiting plate 221 and a second limiting plate 222. The first limiting plate 221 is fixedly mounted on the fixing plate 210. The first limiting plate 221 is provided with a first notch 223, and the second limiting plate 222 is provided with a second notch 224. The first notch 223 and the second notch 224 together form a clearance channel 225 for avoiding the pipeline of the transfer box. The second limiting plate 222 can rotate relative to the first limiting plate 221 to jointly fix or release the pipeline of the transfer box.

[0051] In this application, the first limiting plate 221 is fixedly mounted on the fixed plate 210, and the second limiting plate 222 is rotatably mounted on the first limiting plate 221, so that the second limiting plate 222 can rotate relative to the first limiting plate 221, allowing the second limiting plate 222 to fit or separate from the first limiting plate 221. The first notch 223 on the first limiting plate 221 and the second notch 224 on the second limiting plate 222 together form a clearance channel 225 for accommodating the pipeline of the transfer box. When the pipeline of the transfer box passes through the first notch 223 of the first limiting plate 221, the pipeline is limited and fixed, so that the second limiting plate 222 fits against the first limiting plate 221, and the clearance channel 225 can fit tightly against the outer contour of the pipeline, thereby fixing the pipeline of the transfer box. When it is necessary to remove the pipes from the transfer box, simply separate the second limiting plate 222 from the second limiting plate 222, which will make it easier to remove the pipes from the limiting member 220.

[0052] Specifically, the first notch 223 on the first limiting plate 221 and the second notch 224 on the second limiting plate 222 together form an obstacle avoidance channel 225. This allows the obstacle avoidance channel 225 to accurately conform to the outline of the pipeline in the transfer box, providing reserved space for the pipeline without affecting its normal layout. This avoids hard interference between the limiting component 220 and the pipeline, ensuring smooth pipeline installation. When it is necessary to fix the pipeline, rotating the second limiting plate 222 closes or partially closes the first notch 223 and the second notch 224. The clamping action of the first limiting plate 221 and the second limiting plate 222 stably locks the pipeline within the obstacle avoidance channel 225, effectively preventing axial movement or radial displacement of the pipeline and ensuring the stability of the pipeline connection. When it is necessary to release the fixation, rotating the second limiting plate 222 in the opposite direction opens the obstacle avoidance channel 225. This allows for quick removal, placement, or maintenance of the pipeline without disassembling the overall structure, greatly simplifying the operation process and reducing maintenance costs.

[0053] like Figure 3As shown, in some embodiments, a hinge 510 is also included, wherein the first blade 511 of the hinge 510 is connected to the first end of the first limiting plate 221, and the second blade 512 of the hinge 510 is connected to the first end of the second limiting plate 222.

[0054] In this application, the first blade 511 of the hinge 510 is connected to the first limiting plate 221, and the second blade 512 is connected to the second limiting plate 222, thereby constructing a stable rotating shaft structure. This allows the second limiting plate 222 to rotate smoothly around the axis of the hinge 510's rotating shaft, ensuring that the second limiting plate 222 can be rotatably mounted on the second limiting plate 222 relative to the first limiting plate 221. This facilitates the fixing or unfixing of the pipeline in the transfer box.

[0055] Specifically, the hinge 510 prevents the second limiting plate 222 from shifting, wobbling, or jamming during rotation, ensuring the alignment accuracy of the first notch 223 and the second notch 224 when closing or opening, and ensuring that the clearance channel 225 can accurately wrap around or completely release the pipeline. Meanwhile, as a mature connecting component, the hinge 510 possesses high structural strength and wear resistance, capable of withstanding the rotational force of the second limiting plate 222 and the slight vibration transmission from the pipeline for extended periods, reducing limiting failures caused by damage to the connection points and extending the overall service life of the limiting component 220. Furthermore, the hinge's simple and reliable installation method makes the assembly process of the first limiting plate 221 and the second limiting plate 222 more convenient, reducing the technological difficulty in manufacturing.

[0056] like Figure 3 As shown, in some embodiments, a fixing component 520 is also included. The fixing component 520 includes a fastening bolt 521 and a fastening nut 522. The second end of the first limiting plate 221 is provided with a first extension 226, and the first extension 226 is provided with a first mounting hole. The second end of the second limiting plate 222 is provided with a second extension 227, and the second extension 227 is provided with a second mounting hole. The fastening bolt 521 passes through the first mounting hole and the second mounting hole in sequence and is connected to the fastening nut 522 to fix the pipeline of the transfer box.

[0057] In this application, a first extension 226 is provided on the first limiting plate 221, and a second extension 227 is provided on the second limiting plate 222. A fastening bolt 521 is sequentially inserted through the first extension 226 and the second extension 227, and the fastening bolt 521 is connected to a fastening nut 522, thereby securing the pipeline of the transfer box. This ensures that the fixing component 520 provides a reliable locking effect for the first limiting plate 221 and the second limiting plate 222 when securing the pipeline, further enhancing the pipeline's fixing effect.

[0058] Specifically, the fixing component 520 consists of a fastening bolt 521 and a fastening nut 522. Through the first extension 226 (and first mounting hole) at the second end of the first limiting plate 221 and the second extension 227 (and second mounting hole) at the second end of the second limiting plate 222, a precise and secure locking structure is formed. When it is necessary to fix the pipeline, the fastening bolt 521 is sequentially inserted into the first and second mounting holes and connected and locked with the fastening nut 522. This ensures that the first limiting plate 221 and the second limiting plate 222 are tightly fitted and fixed, so that the clearance channel 225 formed by the two firmly encloses the pipeline. This effectively prevents the limiting plates from loosening due to equipment vibration, external impact, etc., and avoids pipeline displacement or detachment, significantly enhancing the stability and safety of pipeline fixing. Furthermore, by adjusting the tightness, it can adapt to the fixing requirements of pipelines of different diameters, improving the adaptability and flexibility of the limiting component.

[0059] like Figure 1 and Figure 2 As shown, in some embodiments, two pipe positioning components 200 are included, which are spaced apart along the extension direction of the base plate 100. One pipe positioning component 200 is used to fix the sewage inlet pipe of the transfer box, and the other pipe positioning component 200 is used to fix the sewage outlet pipe of the transfer box.

[0060] In this application, two pipe positioning components 200 are provided. Both pipe positioning components 200 are set on the base plate 100 and are spaced apart, so that one pipe positioning component 200 can fix the sewage inlet pipe and the other pipe positioning component 200 can fix the sewage outlet pipe.

[0061] Specifically, the two pipe positioning components 200, which are spaced apart along the extension direction of the base plate 100, can clearly separate the inlet pipe and the outlet pipe, avoiding the inlet pipe and the outlet pipe from crossing, tangling or squeezing each other during the arrangement process, and also reducing the risk of wear or failure caused by mutual interference of pipes.

[0062] like Figure 1 and Figure 2 As shown, in some embodiments, the flange positioning component 300 includes a flange positioning plate 310 and a first support rib 320. The lower end of the flange positioning plate 310 and the lower end of the first support rib 320 are both connected to the base plate 100. The first support rib 320 is connected to the flange positioning plate 310. The flange positioning plate 310 is provided with flange positioning holes for positioning the flange of the transfer box.

[0063] In this application, the flange positioning plate 310 is connected to the base plate 100, and one side of the flange positioning plate 310 is connected to the first support rib 320. The flange positioning plate 310 is provided with flange positioning holes so that it can be positioned and installed with the flange of the transfer box. The first support rib 320 can enhance the load-bearing capacity of the flange positioning plate 310 and ensure the stability of the structure.

[0064] Specifically, the flange positioning plate 310, as a component that directly contacts the flange plate, is connected at its lower end to the base plate 100, forming a vertical foundation support. The flange positioning holes provided on the flange positioning plate 310 can precisely match the mounting holes of the flange plate. The flange plate can be firmly fixed to the flange positioning plate 310 by bolts and other connecting parts, ensuring that the flange plate will not shift or rotate horizontally during assembly and use. This provides a precise alignment reference for the sealing connection between flanges, effectively reducing problems such as sealing failure and media leakage caused by flange misalignment.

[0065] The lower end of the first support rib 320 is connected to the base plate 100 and also to the flange positioning plate 310, forming a triangular stable support system. The support rib can disperse the radial force and bending moment borne by the flange positioning plate 310. Especially when the flange connection transmits medium pressure or is subjected to external vibration, it can prevent the positioning plate from deforming or tilting due to excessive force, significantly enhancing the structural rigidity and load-bearing capacity of the positioning plate and extending the service life of the positioning component.

[0066] like Figure 1 and Figure 2 As shown, in some embodiments, two mounting plate positioning members 400 are included, which are spaced apart along the extension direction of the base plate 100.

[0067] In this application, two mounting plate positioning members 400 are provided so that they correspond to the position of the mounting plate of the transfer box, thereby ensuring a stable connection with the mounting plate.

[0068] like Figure 1 and Figure 2 As shown, in some embodiments, the mounting plate positioning member 400 includes a mounting plate bracket 410, which is provided with a plurality of oblong holes 411 for fixing the mounting plate of the transfer box, and the plurality of oblong holes 411 are arranged at vertical intervals.

[0069] In this application, the mounting plate bracket 410 serves as the direct load-bearing structure for the mounting plate, providing a stable support foundation and ensuring that the mounting plate will not shift due to external forces or vibrations. The multiple oblong holes 411 on the bracket offer adjustable allowance along their length, accommodating positional deviations caused by manufacturing errors or accumulated assembly errors during installation, reducing assembly difficulties due to insufficient hole precision. Furthermore, the multiple oblong holes are spaced vertically, allowing for selection of appropriate hole positions for fixing based on the mounting plate's size, weight distribution, or actual installation requirements. This multi-point fixing enhances the connection strength between the mounting plate and the bracket, preventing deformation caused by uneven stress on the mounting plate, and allows for flexible adjustment of the mounting plate's vertical installation height to meet specific positional requirements under different working conditions.

[0070] like Figure 1 and Figure 2 As shown, in some embodiments, the base plate 100 is provided with a positioning hole 110 and a clearance hole 120. The transfer box is inserted into the positioning hole 110, and the sewage pipe of the transfer box is inserted into the clearance hole 120 and fixed on the pipeline positioning component 200.

[0071] In this application, the positioning hole 110 can position and fix the tank of the transfer box, and the clearance hole 120 can avoid the sewage pipe of the transfer box, so that the sewage pipe passes through the clearance hole 120 and is fixed on the pipeline positioning component 200.

[0072] like Figure 1 and Figure 2 As shown, in some embodiments, the pipeline positioning component 200 further includes a second support rib 230, which is connected to the fixing plate 210 and the base plate 100 respectively.

[0073] In this application, the second support rib 230 is connected to both the fixing plate 210 and the base plate 100, forming a stable triangular support structure between the fixing plate 210 and the base plate 100. This effectively disperses various forces from the pipeline borne by the fixing plate 210, preventing it from tilting, bending, or even breaking due to excessive force, significantly improving the load-bearing capacity and deformation resistance of the fixing plate 210. Simultaneously, the presence of the second support rib 230 makes the connection between the fixing plate 210 and the base plate 100 tighter and more secure, reducing the relative displacement between them. This ensures that the fixing effect of the limiting member 220 on the pipeline is not affected by structural loosening, ensuring that the pipeline remains in a stable fixed state and reducing the risk of pipeline detachment or displacement due to instability in the pipeline positioning member structure.
