[0003] During the assembly of the Fuxing high-speed EMU body, the chassis is placed first, followed by the end wall, then the side wall, and finally the roof. The roof is the last large component to be installed during the assembly process. The connection between the roof and the side wall is two 25m long lap welds, with the roof on the outside and the side wall on the inside. Therefore, it is usually necessary to adjust the flanges of the profiles around the roof to adapt to the misalignment, groove width and other dimensions of the welds between the roof and the side wall and the end wall. When adjusted with rigid tooling tools and after all welds are completed, the contour of the middle of the roof will change under the action of rigid constraint stress. Therefore, mechanical adjustment is required on the front of the roof after welding, and the process support rod is used to pull or push the inside of the car body to ensure that the contour meets the relevant requirements. The entire installation process is complicated and time-consuming, and has certain risks. In addition, the operator has been repeating the same work. Multiple mechanical adjustments have led to reduced strength of the car body profile and uneven appearance.

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] The utility model provides a self-adaptive adjustment device for the roof profile of a rail vehicle, wherein the roof 1 comprises a roof panel profile 11, and the self-adaptive adjustment device comprises a self-adaptive module for rigidly constraining the roof profile, a pressure module 3 and an adjustment module, wherein:

[0032] The adaptive module comprises a span beam 2 and an adaptive pressing block, wherein the span beam 2 is straddled on the top of the roof panel profile 11, and the adaptive pressing block is at least arranged at the position where the span beam 2 corresponds to the flange of the roof panel profile 11, and the fixed angle and fixed position of the adaptive pressing block and the span beam 2 and the position of the pressing surface of the adaptive pressing block can be adaptively adjusted according to the structural characteristics of the flange of the roof panel profile 11;

[0033] A pressure module 3, one end of which is pressed against the adaptive module, and the other end of which is connected to the adjustment module, so as to apply a pressing force to the adaptive module;

[0034] The adjusting module is connected to the pressure applying module 3 and is used to adjust the position of the pressure applying module 3 .

[0035] like Figure 1 As shown, the body of the rail vehicle includes side walls and a roof 1, and the roof 1 includes a roof panel profile 11 and an internal supporting structure 12. The top surface of the roof panel profile 11 is a plane or slightly curved with a small curvature. The two ends of the top surface of the roof panel profile 11 are bent toward the side wall through an arc structure to form a side wall. The end of the side wall is welded and fixed to the side wall and the end wall. During welding, the flange position and flange structure of the end of the roof panel profile 11 are adjusted according to the staggered edges, groove width and other dimensions of the welds between the roof 1 and the side wall and the end wall. During the adjustment and welding process, the roof panel profile 11 needs to be rigidly constrained to prevent the roof panel profile 11 from moving and deforming during the process.

[0036] In conventional technology, rigid constraints are only applied to the flange structure of the roof panel profile 11, and force is applied from the side to the roof panel profile 11 toward the center of the vehicle compartment. If the force is too large, on the one hand, the top surface of the roof panel profile 11 will bulge upward, and on the other hand, deformation will occur at the force-bearing part, thereby deforming the profile of the roof panel profile 11. To this end, the utility model provides an adaptive adjustment structure that can prevent the roof panel profile 11 from deforming.

[0037] The present embodiment provides a rail vehicle roof profile adaptive adjustment structure adaptive module, the adaptive module includes a span beam 2 and an adaptive pressure block, such as Figure 1 As shown, the cross beam 2 spans over the top surface of the roof 1 along the transverse direction of the vehicle body (the length direction of the vehicle body, the running direction is the longitudinal direction), and is pressed onto the roof panel profile 11 to produce a rigid constraint on the roof panel profile 11.

[0038] The cross-sectional structure of the cross beam 2 is similar to that of the roof panel profile 11, including a standard roof profile 21 in the middle section and arc-shaped pressed profiles 22 at both ends. The standard profile 21 is directly pressed on the top surface of the roof panel profile 11, rigidly constraining the top surface of the roof panel profile 11 to prevent the top surface from bulging upward.

[0039] The two ends of the standard profile 21 are provided with arc-shaped pressed profiles 22 . The structure of the arc-shaped pressed profile 22 is similar to the structure of the side walls at both ends of the roof panel profile 11 . The arc-shaped pressed profile 22 is pressed on the side walls to rigidly constrain the roof panel profile 11 from the side.

[0040] The two sides (towards the direction of movement of the vehicle body) and the two ends (the lateral direction of the vehicle body, perpendicular to the direction of movement) of the cross beam 2 are closed and welded with plates, thereby improving the overall strength of the cross beam 2 and being able to provide sufficient rigidity constraints on the roof panel profile 11. When fully pressed together, the roof panel profile 11 is prevented from having the problems of top protrusion and side deformation as mentioned above during construction.

[0041] Furthermore, although the top of the roof panel profile 11 has a standard shape, the length, arc curvature and other structural features of the two ends of the roof panel profile 11 may be slightly different depending on the vehicle model. In order to improve the applicability of the device, an adaptive pressure block is provided on the cross beam 2. The adaptive pressure block can adjust the angle of the pressing surface to adapt to different vehicle models.

[0042] There are multiple adaptive pressure blocks, which are respectively arranged at the arc-shaped pressing profiles 22 at both ends. According to the structural form of the two ends of the roof panel profile 11, the pressing surface is adjusted so that the pressing surface of the adaptive pressure block is pressed on the side wall of the roof panel profile 11. Preferably, it is pressed around the flange structure to prevent the roof panel profile 11 from being deformed and reduce the stress at the flange.

[0043] A slide groove is provided on the bottom surface of the arc-shaped pressed profile 22 (the side facing the roof panel profile 11), and the top of the adaptive pressing block is inserted into the slide groove and can slide along the slide groove to adjust the position to adapt to side walls of different lengths.

[0044] Furthermore, the top surface of the adaptive pressing block is arc-shaped, or the part of the adaptive pressing block inserted into the slide groove is spherical, which can adaptively adjust the connection angle with the arc-shaped pressing profile 22, that is, adjust the angle of the pressing surface to adapt to side walls with different structural forms.

[0045] Alternatively, the adaptive pressure block is slidably connected to the slide groove through an insertion rod, and the insertion rod and the adaptive pressure block are connected through a ball joint or a structure similar to a ball joint, so that the connection angle between the adaptive pressure block and the arc-shaped pressing profile 22 is adjusted according to the inclination angle and structural form of the side wall of the roof panel profile 11, especially the flange, so as to adjust the angle of the pressing surface.

[0046] In order to improve the overall strength of the top of the roof panel profile 11 and facilitate the assembly and fixation of other structures, the top of the roof panel profile 11 may have different pressing or cutting. Therefore, an adaptive pressing block is also provided on the bottom surface of the standard profile 21.

[0047] A slide groove is provided on the bottom surface of the standard profile, and the adaptive pressing block is slidably connected to the slide groove. The pressing surface of the adaptive pressing block protrudes from the bottom surface of the standard profile, and is used to press the concave pressing position on the top surface of the roof panel profile 11. The adaptive pressing block can slide in the slide groove and adjust its position to adapt to the profile structure of different widths.

[0048] Each adaptive pressure block is detachably connected to the cross beam 2 and has a variety of different specifications. Whether it is necessary to install the adaptive pressure block, select the appropriate specifications, and adjust the corresponding position of the adaptive pressure block on the cross beam 2 is determined according to the specific structural characteristics of the roof to be constrained. During the pressing process, as described above, the assembly angle with the cross beam 2 is automatically adjusted according to the structural characteristics of the roof panel profile 11, especially the inclination angle (arc curvature, etc.) of the side wall, thereby adjusting the angle of the pressing surface to match the roof panel material, performing comprehensive rigid constraints on the roof panel material, and preventing deformation of the roof contour.

[0049] The adaptive adjustment device also includes a pressure module 3, which applies pressure to the cross beam 2, thereby generating a rigid constraint on the roof panel profile 11, and by applying pressure, preventing the adaptive module from moving on the roof 1, making it impossible to achieve effective rigid constraint.

[0050] In this embodiment, the pressure module 3 is a hydraulic rod 31 , one end of which abuts against the top surface of the cross beam 2 to provide a restraining force for the adaptive module, and is pressed onto the roof 1 .

[0051] The bottom of the hydraulic rod 31 presses against the top surface of the cross beam 2. Preferably, there are two hydraulic rods 31, which press against the connection between the standard profile 21 and the arc-shaped pressed profile 22 respectively, so as to apply pressure to the top surface and the side surface of the roof panel profile 11 at the same time.

[0052] A force conduction seat is provided on the top surface of the connection between the standard profile 21 and the arc-shaped pressed profile 22. The cross-section of the force conduction seat is roughly a right-angled triangle, one right-angled side is parallel to the ground, the hydraulic rod 31 is pressed against the right-angled side, and the other right-angled side is flush with the side wall of the vehicle body; the hypotenuse is an arc-shaped side, which is pressed against the connection between the standard profile 21 and the arc-shaped pressed profile 22, and the hydraulic rod 31 is pressed against the top surface. Through the arc-shaped inclined surface, the pressure of the hydraulic rod 31 is evenly transmitted to the adaptive module, thereby providing uniform pressure on the roof panel profile 11.

[0053] By providing a force transmission seat (not shown in the figure), the local pressure of the hydraulic rod 31 is evenly distributed to the entire adaptive module, while ensuring the pressing force, the force application area is expanded to prevent excessive local pressure from causing local deformation of the roof panel profile 11.

[0054] The hydraulic rod 31 is connected to the adjustment module through the telescopic module. The longitudinal height of the hydraulic rod 31 is adjusted through the telescopic module. When there is no need to press, the telescopic module contracts and the hydraulic rod 31 rises to the highest position. During the assembly process, when the roof 1 and the side wall need to be pressed together, the telescopic module drives the hydraulic rod 31 to move down to a predetermined height. The output rod of the hydraulic rod 31 extends out under the action of the hydraulic pressure and presses against the top surface of the force transmission seat. The rated pressure is output through automatic control, and the pressure is evenly distributed to the adaptive module through the force transmission seat.

[0055] Furthermore, the adaptive module has a certain width and is pressed onto the top surface of the roof 1. As the welding progresses, the pressing position needs to be adjusted. The overall volume of the adaptive module is relatively small, and the pressing position can be adjusted by manual pushing and cooperation of the on-site operator. In order to prevent the adaptive module from scratching the roof panel profile 11 during movement, a rubber pad that can produce a certain elastic deformation is provided on the pressing surface of the adaptive module. On the one hand, the rubber pad can produce elastic deformation to allow the adaptive module to be in soft contact with the roof panel profile 11, thereby preventing the adaptive module from making hard contact with the roof panel profile 11 during pressing, thereby preventing the roof panel profile 11 from being damaged by pressing; on the other hand, it can also prevent the roof panel profile 11 from being scratched when the adaptive module is moved; on the other hand, providing a rubber pad on the adaptive pressing block can further realize the adaptive ability of the pressing surface.

[0056] The top of the pressure module 3, namely the hydraulic rod 31, is connected to the adjustment module, and the position is adjusted by the adjustment module so that the hydraulic rod 31 is located directly above the force conduction seat.

[0057] The adjustment module includes a gantry (not shown in the figure). The gantry is a common structure and the specific structure is not described in detail. A mounting rail 4 is provided on the crossbeam of the gantry. The top of the hydraulic rod 31 is slidably connected to the mounting rail 4 directly or through a telescopic module, so that the pressure module 3 can slide along the mounting rail 4. According to the width of the vehicle model, the relative position between the two hydraulic rods 31 is adjusted, that is, the position of the hydraulic rod 31 is adjusted along the lateral direction of the vehicle body.

[0058] Two parallel slide rails are arranged on the floor of the production workshop. The bottoms of the two longitudinal beams of the gantry are respectively slidably connected with a slide rail, driving the gantry to move along the slide rails, thereby adjusting the position of the hydraulic rod 31 along the length direction of the vehicle body, and cooperating with the adjustment of the mounting rail 4, so that the hydraulic rod 31 is directly above the force transmission seat.

[0059] Furthermore, since the movement accuracy of the sliding guide rail and the slide rail is relatively low, during the adjustment process, the hydraulic rod 31 cannot be directly above the force transmission seat. Therefore, in this embodiment, a wrench 32 is provided on the hydraulic rod 31. After the position of the pressure module 3 is roughly adjusted by the sliding guide rail and sliding, the on-site operator pushes the wrench 32 to fine-tune the position of the hydraulic rod 31 so that the hydraulic rod 31 is directly above the force transmission seat.

[0060] During the overall assembly, the roof 1 is buckled onto the side wall and welded to fix. Before welding, according to the structural characteristics of the roof panel profile 11, a suitable adaptive pressure block is selected, and the adaptive pressure block is adjusted to a suitable position, and then the adaptive module is placed on the side wall of the roof panel profile 11 at the position where the flange needs to be adjusted; the pressure module 3 is driven to move by the adjustment module, and the position of the pressure module 3 is roughly adjusted, and then the position of the hydraulic rod 31 is finely adjusted by the wrench 32. Specifically, after fine adjustment, the telescopic module drives the hydraulic rod 31 to move downward. During the movement of the hydraulic rod 31, the end of the hydraulic rod 31 is pressed against the center position of the top surface of the force transmission seat by the wrench 32.

[0061] According to the preset program, the hydraulic rod 31 outputs a predetermined pressure, and the pressure is evenly and forcefully applied to the entire adaptive module through the force transmission seat, and then acts on the entire roof 1, rigidly constraining the roof contour, realizing the roof 1 without external adjustment, and improving the installation efficiency of the roof 1 and the side wall and the product quality.

[0062] After the flange structure adjustment at the adaptive adjustment module is completed, the pressure module 3 is decompressed to release the adaptive module, so that the adaptive module is moved to the next position where the flange needs to be adjusted by pushing, and the previous operation is repeated until the roof 1 of the entire car is buckled with the side wall of the car.

[0063] It should be noted that during the fastening process, the position of the pressure module 3 is adjusted by moving the position of the gantry. In actual applications, the position of the gantry can be fixed, and the adaptive module is moved to the pressure module 3 by moving the vehicle body, without any requirements or limitations.

[0064] During the overall pressing process, the adaptive module is pushed to move along the roof 1. After it moves to the specified position, the adjustment module is controlled by the controller to drive the pressure module 3 to move. These processes can be completed by only one operator, saving labor. In addition, the movement of the pressure module 3 is achieved by the controller, reducing labor intensity.

[0065] In summary, the rail vehicle roof profile adaptive adjustment device provided by the utility model has the following technical advantages compared with the prior art:

[0066] The core middle part of the roof profile adaptive module adopts the standard roof profile, and the two sides and ends are made of fully enclosed plates welded to ensure sufficient rigidity to constrain the roof and avoid deformation of the roof during construction;

[0067] The hydraulic rod mounting track is installed on the gantry robot frame, and the hydraulic rod is installed on the track. The two hydraulic rods can move along the lateral direction of the roof to adjust the pressing position. Before the overall construction, the adaptive module is placed at the roof position where the size needs to be adjusted. The hydraulic rod acts on the force transmission mounting seat, and the force is evenly and forcefully applied to the entire adaptive module through the mounting seat, and then acts on the entire roof to rigidly constrain the roof contour.

[0068] The entire installation process is convenient, safe and efficient, which not only reduces repetitive work, but also saves labor. The operation is changed from two people on both sides to one person, which greatly reduces the labor intensity and realizes the roof outside without adjustment.

[0069] The use of this device can effectively standardize the process of Fuxing EMU car body assembly operations, greatly improving installation efficiency and product quality.

[0070] As described above, similar technical solutions can be derived from the given solution content. However, any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still fall within the scope of the technical solution of the utility model.
