[0039] The following is combined with Figures 1 to 5 The present invention describes a vehicle body maintenance isolation device applicable to the body of a rail vehicle. The body includes side walls, a top plate, and a bottom plate. The side walls, top plate, and bottom plate together form a cylindrical structure. A floor seat is provided on the upper side of the bottom plate. Multiple floor seats are provided. The floor seats are rectangular or block structures similar to rectangles.

[0040] like Figure 1 and Figure 2 As shown, the vehicle body maintenance isolation device of the present invention includes a frame, a base frame, a top tarpaulin 6, and an end tarpaulin 7.

[0041] The frame has first connecting structures on both sides, which are suitable for detachable connection with the side walls. The size and shape of the frame are designed according to the specific structure of the vehicle body to ensure stable support within the vehicle body.

[0042] The base is located below the frame and is designed to mate with the base plate. The base frame is designed to accommodate various structures that may exist on the base plate, such as floor supports, to facilitate installation. At the same time, the base frame also provides protection for structures such as floor supports on the base plate.

[0043] The top tarpaulin 6 is installed along the length of the vehicle body. One end is detachably connected to the frame via a second connecting structure, and the other end is detachably connected to the end of the vehicle body opposite to the frame via a third connecting structure. This connection method ensures that the top tarpaulin 6 fits tightly against the vehicle body, effectively preventing aluminum shavings and dust from entering the interior of the vehicle.

[0044] The end tarpaulin 7 is located inside the frame and is detachably connected to the frame via a structure such as hooks or bolts.

[0045] The vehicle body maintenance isolation device provided by this invention detachably connects the frame to the side wall via a first connecting structure, fixing its position. The top tarpaulin 6 is connected to both the frame and the end of the vehicle body. The frame's support prevents the top tarpaulin 6 from sagging in the middle, achieving a good protective effect and effectively blocking aluminum shavings and dust. Furthermore, the frame and base are separate designs, which facilitates installation by avoiding interference with structures such as the floor base on the base plate. The base also protects these structures, preventing aluminum shavings and dust from entering and improving the safety and efficiency of maintenance operations. Simultaneously, the device's design considers various practical situations and usage requirements, exhibiting high practicality and convenience. Using this device eliminates the need for manual hanging of the top tarpaulin 6 with ropes, reducing labor intensity and avoiding the instability of manual protection quality.

[0046] In some embodiments of the present invention, the frame includes a first upright 1, a second upright 2, and a crossbeam.

[0047] The first upright 1 and the second upright 2 are vertically arranged and are respectively adapted to be detachably connected to the corresponding side walls of the vehicle body via a first connecting structure. The first upright 1 and the second upright 2 are curved rod structures, and their shapes can be designed according to the shape of the side walls. When the first upright 1 and the second upright 2 are connected to the corresponding side walls via the first connecting structure, the side walls of the first upright 1 and the second upright 2 fit against the inner wall of the side wall, which not only achieves a better protective effect, but also makes their fixation to the side wall more stable and firm. The first upright 1 and the second upright 2 are located on the upper side of the base. Preferably, the lower ends of the first upright 1 and the second upright 2 are in contact with the base, and the base provides support for the first upright 1 and the second upright 2, reducing the stress on the first connecting structure and improving the sealing effect.

[0048] Optionally, the first support 1 and the second support 2 are respectively provided with a sealing element 5 on the opposite side. The sealing element 5 can be an elastic element such as sealing silicone. The sealing element 5 is suitable for contacting and cooperating with the inner wall of the side wall to increase the sealing of the contact position between the first support 1 and the second support 2 and the side wall, and can adapt to the complex structure of the inner wall of the side wall by utilizing the deformation capacity of the sealing element 5.

[0049] Both ends of the crossbeam are detachably connected to the top ends of the first support 1 and the second support 2 via a fourth connecting structure. The fourth connecting structure includes a first mounting ring, a second mounting ring, a first sliding pin 12, and a locking element 11. The first mounting ring is fixedly connected to one side of the first support 1 or the second support 2 by means of welding, riveting, or bolting. The second mounting ring is fixedly connected to the crossbeam by means of welding, riveting, or bolting. The first sliding pin 12 is movably engaged with the first and second mounting rings. When the first sliding pin 12 slides to simultaneously pass through the first and second mounting rings, it can limit the movement of the crossbeam and the first and second supports 1 and 2; when the first sliding pin 12 slides to engage only with one of the first and second mounting rings, it can release the limitation on the crossbeam and the first and second supports 1 and 2. The locking element 11 is provided on the first support 1 or the second support 2 to lock the position of the first sliding pin 12.

[0050] Optionally, the locking member 11 is a bolt structure. The locking member 11 passes through the slide groove provided in the first sliding pin 12 and is threadedly connected to the first support 1 or the second support 2. When the locking member 11 is tightened so that the head of the locking member 11 presses against the first sliding pin 12, the position of the first sliding pin 12 can be locked. When the locking member 11 is loosened, the locking member 11 can slide.

[0051] Both ends of the crossbeam are provided with downward bends, and the lower ends of the downward bends are connected to the corresponding first upright 1 or second upright 2 through a fourth connecting structure. By providing downward bends, the crossbeams can be adapted to the top corners of the vehicle body and also allow the top tarpaulin 6 to bend naturally on both sides, thereby achieving better support and sealing effects.

[0052] The crossbeam includes a first beam body 3 and a second beam body 4. One end of the first beam body 3 is detachably connected to the second beam body 4 via a fifth connecting structure, and the other end is detachably connected to the top of the first upright 1. The end of the second beam body 4 facing away from the first beam body 3 is detachably connected to the top of the second upright 2. The fifth connecting structure includes a third mounting ring, a fourth mounting ring, and a second sliding pin. The third mounting ring is fixedly connected to the first beam body 3 by means of welding, riveting, or bolting, for example. The fourth mounting ring is fixedly connected to the second beam body 4 by means of welding, riveting, or bolting, for example. The second sliding pin is movably inserted into the third and fourth mounting rings.

[0053] Optionally, the crossbeam is detachably connected to the inner wall of the vehicle body via a first connecting structure, increasing the strength of the crossbeam's fixation.

[0054] Combination Figure 4The crossbeam is detachably connected to one end of the top tarpaulin 6 via a second connecting structure. Specifically, an extension plate 17 is provided on the upper part of one side of the crossbeam, and one end of the top tarpaulin 6 overlaps the upper side of the extension plate 17 of the crossbeam. The second connecting structure includes a fastening clip 15 and a fastening bolt 16. The fastening clip 15 has an n-shaped structure and is fitted on the outside of the extension plate 17. The fastening bolt 16 is threadedly connected to the fastening clip 15. One end of the fastening bolt 16 located inside the fastening clip 15 abuts against the top tarpaulin 6, or the other end of the fastening bolt 16 located inside the fastening clip 15 passes through the hanging hole at the end of the top tarpaulin 6 and abuts against the extension plate 17.

[0055] The end of the top tarpaulin 6 facing away from the crossbeam is detachably connected to the end of the vehicle body facing away from the frame via a third connecting structure. The third connecting structure can be a hanging hole located at the end of the top tarpaulin 6, which can be attached to a structure such as a bolt or hook on the top of one end of the vehicle body.

[0056] In this embodiment of the invention, the frame is designed as a split structure, which facilitates movement and installation. This reduces the space requirements during installation, and also makes it easier to avoid obstructions from welds, windows, and other structures on the side walls when the first upright 1, the second upright 2, and the crossbeam are installed separately.

[0057] The following is combined with Figure 3 The first connection structure of this embodiment of the invention will be described exemplarily as follows:

[0058] The first connection structure includes a mounting component 13 and a mounting bolt 14. The mounting component 13 is provided with a mounting groove, and the mounting bolt 14 passes through the mounting groove and is connected to the side wall. In this embodiment, the mounting groove extends along the length of the vehicle body, allowing for some adjustment space in the mounting position of the mounting bolt 14, thus providing better adaptability.

[0059] Optionally, the middle part of the mounting component 13 is fixedly connected to the frame, and the mounting component 13 is provided with mounting grooves on both sides of the frame, with at least one mounting bolt 14 corresponding to each mounting groove. This can increase the firmness of the fixation.

[0060] Optionally, the mounting part 13 is provided with a mating groove on the side that contacts the vehicle body. This mating groove can mate with the weld of the vehicle body, which can improve the sealing effect and also serve as a positioning function.

[0061] Combination Figure 5 In some embodiments of the present invention, a groove is provided on the lower side of the base, and multiple clearance grooves are provided on both sides of the base along the length direction of the vehicle body. The clearance grooves can avoid the floor seat, thereby facilitating the sliding of the base to the underside of the frame along the length direction of the vehicle body, or sliding out from under the frame.

[0062] Optionally, the base includes a first base body 8 and a second base body 9, which are arranged along the width direction of the vehicle body and are spliced ​​together. This facilitates handling and installation.

[0063] Optionally, the base can be detachably equipped with multiple protective boxes 10, which are located outside multiple clearance slots and correspond one-to-one with each clearance slot. Specifically, the base is provided with limit plates on both sides of the clearance slots, and the ends of the protective boxes 10 are inserted between the limit plates on both sides of the clearance slots. The protective boxes 10 can be placed over the outside of the floor base to provide a shielding function.

[0064] In some embodiments of the present invention, the frame and base are made of aluminum alloy plates, which not only reduces the weight of the entire device and makes it easier for employees to use, but also provides better protective support.

[0065] The specific operating steps for using the vehicle body inspection and isolation device in this embodiment are as follows:

[0066] Based on the specific structure of the vehicle body, the first connecting structures on both sides of the frame are detachably connected to the side walls to ensure that the position of the frame is fixed.

[0067] The base frame is placed below the skeleton so that it contacts and engages with the base plate, thus protecting the base plate.

[0068] The top tarpaulin 6 is unfolded along the length of the vehicle body and detachably connected to the frame and the vehicle body through the second and third connecting structures, respectively, to ensure that the top tarpaulin 6 fits tightly against the vehicle body.

[0069] After completing the above steps, the entire device is installed and vehicle body maintenance work can begin. During the operation, the device can effectively prevent aluminum shavings and dust from entering the vehicle compartment, improving the safety and efficiency of the maintenance work.

[0070] After the maintenance work is completed, first remove the connecting structure between the top tarpaulin 6 and the frame and body, then remove the frame and underframe. The entire disassembly process is simple and does not require the use of additional tools or equipment.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
