Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicles, and in particular to a protective device and a protective method for a rail vehicle floor cloth. Background Art

[0002] Currently, the floor coverings used on urban rail vehicles are made of PVC or rubber. Due to poor protection, the floor coverings can become damaged over time. If the damage exceeds the specified level, the floor coverings must be replaced, which is extremely costly. Therefore, after the floor coverings are laid and before entering the final assembly process, they must be fully protected to prevent damage from tooling, equipment, and the installation of the vehicle's own equipment during final assembly. This prevents the floor coverings from being stepped on, soiled, or scratched by people entering and exiting the vehicle. Furthermore, it prevents damage from adhesives used during final assembly that fall directly onto the floor coverings.

[0003] Some traditional technologies involve laying crystal panels on the vehicle's interior floor cloth and then using wide plastic tape to secure the seams of the protective material. While this method can protect against hard objects, scratches, and contamination from adhesive, it must be laid across the entire length of the vehicle. This requires cutting the panels at the device's installation location before installing in-vehicle equipment. This requires re-filling the cut areas for the next use, resulting in low efficiency.

[0004] Therefore, how to solve the problem of low operating efficiency caused by the need for on-site cutting and filling when protecting the floor cloth of railway vehicles in the existing technology has become an important technical problem to be solved by those skilled in the art.

[0044] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0045] The following combination Figures 1 to 3 A protective device for a railway vehicle floor cloth according to an embodiment of the present invention is described.

[0046] like Figures 1 to 3 As shown, an embodiment of the present invention provides a protective device for a rail vehicle floor cloth, comprising a first special-shaped plate group, a second special-shaped plate group, a third special-shaped plate group, a fourth special-shaped plate group, a first standard plate group, and a second standard plate group.

[0047] Specifically, the floor cloth covers the floor of the rail vehicle's interior including the door area 1, the central pillar area 2, the equipment installation area 3, and the vacant area 4. The vacant area 4 is an area on the rail vehicle's floor cloth that does not need to be directly connected to other components.

[0048] The projection area of ​​the column 5 on the floor cloth is located inside the central column area 2, and the projection area of ​​the device 6 on the floor cloth is located inside the device installation area 3. In other words, the central column area 2 is slightly larger than the projection area of ​​the column 5 on the floor cloth, and the device installation area 3 is slightly larger than the projection area of ​​the device 6 on the floor cloth.

[0049] The first special-shaped plate group, the first standard plate group, the second standard plate group and the fourth special-shaped plate group can cover any position of the central column area 2, the equipment installation area 3, the vacant area 4 and the door area 1 respectively.

[0050] When the rail vehicle enters the final assembly workshop, the first special-shaped plate group, the second special-shaped plate group, the third special-shaped plate group, the fourth special-shaped plate group, the first standard plate group and the second standard plate group are all covered on the floor cloth, which can fully protect the floor cloth.

[0051] Both the first and second shaped panels 10, 11 are used to cover the central pillar area 2. Before installing the central pillar 5, the first shaped panel set can be used to cover any portion of the central pillar area 2, providing comprehensive protection. When installing the pillar 5, the first shaped panel 10 is removed and the second shaped panel set is placed in the central pillar area 2 to protect the area outside the area where the pillar 5 will be installed. After the second shaped panel set is in place, the pillar 5 can be installed.

[0052] Both the first standard panel set and the third special-shaped panel set are used to cover the equipment installation area 3. Before installing equipment 6, the first standard panel set can be used to cover any location in the equipment installation area 3, providing comprehensive protection. When it is time to install equipment 6, the first standard panel set is removed and the third special-shaped panel set is installed in the equipment installation area 3 to protect the area outside the area where equipment 6 is to be installed. After the third special-shaped panel set is installed, the equipment 6 can be installed.

[0053] In this way, the floor cloth is divided into zones, and two different shapes of plate groups are configured for the central column area 2 and the equipment installation area 3 respectively. When the column 5 or the equipment 6 is not installed, one plate group is used for protection. When the column 5 or the equipment 6 is installed, the other plate group is directly replaced to use the other plate group for protection. There is no need for on-site cutting and filling, which reduces the use of tape, reduces on-site operations, saves time, and is conducive to improving work efficiency.

[0054] In the embodiment of the present invention, the first standard plate group includes at least two first standard plates 7 , and the dimension of the first standard plates 7 along the transverse direction of the rail vehicle is slightly larger than the dimension of the device 6 along the transverse direction of the rail vehicle.

[0055] It should be noted that the transverse direction of a rail vehicle is the left and right direction of the rail vehicle. Figure 1 The direction indicated by m in the figure; the longitudinal direction of the rail vehicle is the front-to-back direction of the rail vehicle, such as Figure 1 The direction indicated by n.

[0056] Equipment 6 is installed near the walls on both sides of the rail vehicle. Referring to the figure, two equipment installation areas 3 are set in one carriage of the rail vehicle.

[0057] For one of the equipment installation areas 3 , only one row of first standard plates 7 needs to be arranged, and each first standard plate 7 in the row is distributed along the longitudinal direction of the rail vehicle.

[0058] Correspondingly, the third special-shaped plate group includes at least two third special-shaped plates 8, and the dimensions of the third special-shaped plates 8 along the longitudinal direction of the rail vehicle are consistent with the longitudinal dimensions of the first standard plates 7 along the rail vehicle. For the same equipment installation area 3, the number of third special-shaped plates 8 required is consistent with the number of first standard plates 7 required.

[0059] Notches are formed in the third shaped plates 8. When the third shaped plates 8 corresponding to the same device installation area 3 are spliced ​​together, the shape of each notch matches the shape of the projection area of ​​the device 6. Each third shaped plate 8 can protect the area of ​​the device installation area 3 that is outside the projection area of ​​the device 6.

[0060] In the embodiment of the present invention, the second standard plate set includes at least two second standard plates 9 .

[0061] The dimensions of the second standard plate 9 along the transverse direction of the rail vehicle are consistent with those of the first standard plate 7, and the dimensions of the second standard plate 9 along the longitudinal direction of the rail vehicle are consistent with those of the first standard plate 7. In other words, the shape and dimensions of the first standard plate 7 are consistent with those of the second standard plate 9, providing greater versatility. Furthermore, the second standard plate 9 can meet the coverage requirements for both the partially vacant area 4 located to one side of the equipment installation area 3 along the longitudinal direction of the rail vehicle and the partially vacant area 4 located to one side of the equipment installation area 3 along the transverse direction of the rail vehicle, and can also be smoothly docked with the first standard plate 7. This ensures that the second standard plates 9 are distributed in rows and columns in the vacant areas 4 along both the transverse and longitudinal directions of the rail vehicle.

[0062] The central pillar area 2 is provided with multiple pillars 5, which are spaced apart longitudinally along the rail vehicle and located at the center of the rail vehicle in the transverse direction. Referring to the figure, the central pillar area 2 is located in the middle of the rail vehicle in the transverse direction, with the equipment installation area 3 and the door area 1 located on either side of the central pillar area 2. Along the transverse direction of the rail vehicle, a row of second standard plates 9 and a row of first standard plates 7 are arranged on one side of the central pillar area 2. The transverse dimensions of the first standard plates 7 and the second standard plates 9 can be determined based on the distance between the central pillar area 2 and the side wall.

[0063] In the embodiment of the present invention, the first shaped plate group includes a first shaped plate 10 for covering any position in the central column area 2. The second shaped plate group includes a second shaped plate 11 for covering any position between two adjacent columns 5 in the central column area 2.

[0064] Specifically, the first special-shaped plate 10 and the second special-shaped plate 11 can be set to be long strips, the size of the first special-shaped plate 10 along the transverse direction of the rail vehicle is consistent with the size of the second special-shaped plate 11 along the transverse direction of the rail vehicle, the size of the first special-shaped plate 10 along the longitudinal direction of the rail vehicle is larger than the size of the second special-shaped plate 11 along the longitudinal direction of the rail vehicle, and the difference between the size of the first special-shaped plate 10 along the longitudinal direction of the rail vehicle and the size of the second special-shaped plate 11 along the longitudinal direction of the rail vehicle is at least larger than the size of the column 5 along the longitudinal direction of the rail vehicle.

[0065] It should be noted that the dimensions of the first and second profiled plates 10, 11 along the transverse direction of the rail vehicle are greater than the dimensions of the uprights 5. Since different types of rail vehicles have different transverse dimensions of their interior spaces, to ensure the versatility of the first and second standard plates 7, 9 across different vehicle types, at least two sets of first and second profiled plates 10, 11 with different widths may be provided.

[0066] In the embodiment of the present invention, the fourth special-shaped plate group includes fourth special-shaped plates 12 , and at least two fourth special-shaped plates 12 are provided.

[0067] 1 and 2. Referring to the figures, along the longitudinal direction of the rail vehicle, the door area 1 is located on both sides of the vacant area 4.

[0068] In this embodiment, the dimensions of the fourth special-shaped plate 12 along the transverse direction of the rail vehicle are aligned with those of the first standard plate 7. Furthermore, the dimensions of the fourth special-shaped plate 12 along the transverse direction of the rail vehicle are aligned with those of the second standard plate 9. This allows the fourth special-shaped plates 12 to be distributed along the transverse direction of the rail vehicle, with each fourth special-shaped plate being connected to the first standard plate 7 and the second standard plate 9, respectively.

[0069] In some embodiments, the fourth shaped plate assembly further includes a fifth shaped plate 13, of which at least two are provided. The transverse dimension of the fifth shaped plate 13 along the rail vehicle is consistent with the transverse dimension of the fourth shaped plate 12 along the rail vehicle. In the longitudinal direction of the rail vehicle, the fifth shaped plate 13 is disposed on one side of the fourth shaped plate 12, with each fifth shaped plate 13 distributed along the transverse direction of the rail vehicle and in contact with the fourth shaped plate 12.

[0070] The fourth special-shaped plate 12 can be directly connected to the first standard plate 7 , the second standard plate 9 or the third special-shaped plate 8 , or can be connected to the first standard plate 7 , the second standard plate 9 or the third special-shaped plate 8 through the fifth special-shaped plate 13 .

[0071] It should be noted that the longitudinal dimensions of the interior spaces of different railcars vary. To ensure universal use of the first standard plate 7 and the second standard plate 9 across different vehicle models, the fifth special-shaped plate 13 can be used to accommodate the longitudinal dimension differences between the interior spaces of individual railcars of different vehicle models. For railcars with smaller longitudinal dimensions, only the fourth special-shaped plate 12 can be used, with the fourth special-shaped plate 12 directly abutting the first standard plate 7, the second standard plate 9, or the third special-shaped plate 8. For railcars with larger longitudinal dimensions, both the fourth special-shaped plate 12 and the fifth special-shaped plate 13 can be used, with the fourth special-shaped plate 12 abutting the first standard plate 7, the second standard plate 9, or the third special-shaped plate 8 via the fifth special-shaped plate 13. This arrangement allows the same protective device for railcar floor coverings to be universally used across two models of railcars.

[0072] According to statistics, in the protective device for railway vehicle floor cloth provided in this embodiment, more than 90% of the panels can be used in common on different vehicle models.

[0073] In the embodiment of the present invention, each edge of each of the first standard plates 7, the second standard plates 9, the third special-shaped plates 8, the fourth special-shaped plates 12, and the fifth special-shaped plates 13 is provided with a plurality of dovetail grooves, with dovetail-shaped protrusions formed between adjacent dovetail grooves. The dovetail-shaped protrusions are adapted to fit within the dovetail grooves.

[0074] By utilizing the dovetail protrusions and dovetail grooves, during operation, two adjacently laid positions of each first standard plate 7, each second standard plate 9, each third special-shaped plate 8, each fourth special-shaped plate 12, and each fifth special-shaped plate 13 can be spliced ​​together, thereby avoiding the use of tape, facilitating disassembly and assembly, and reducing the difficulty of operation. The interaction between the dovetail grooves and the dovetail protrusions can prevent the problem of misalignment.

[0075] The sizes of the first standard plates 7, the second standard plates 9, the first special-shaped plates 10, the second special-shaped plates 11, the third special-shaped plates 8, the fourth special-shaped plates 12 and the fifth special-shaped plates 13 are relatively small and easy to stack. After disassembly, they can be stacked and stored for a long time without wrinkles or deformation. This solves the problem of large protective materials being prone to deformation and short service life during stacking, storage and transportation after disassembly. It also solves the problem of large protective materials being difficult to clean and causing pollution to floor cloths due to repeated laying.

[0076] In this embodiment, at least each first standard plate 7, each second standard plate 9, each third special-shaped plate 8, each fourth special-shaped plate 12, and each fifth special-shaped plate 13 is provided with a coding mark to identify the installation location and applicable vehicle type of each plate. By storing the plates in separate areas and in order during installation, the installation location of each plate can be more quickly identified, improving installation efficiency and preventing misplacement.

[0077] In addition, corresponding coding marks are also provided on the first special-shaped plate 10 and the second special-shaped plate 11 .

[0078] The above coding representation can be set by laser engraving.

[0079] The coding labels can be TY, TA, or TB, where TY indicates universal use for Type A and B rail vehicles, TA indicates exclusive use for Type A rail vehicles, and TB indicates exclusive use for Type B rail vehicles. Numerical suffixes can be added after TY, TA, and TB to clearly identify the placement of each plate. After disassembly, the plates are placed separately according to their numbers, avoiding problems such as mixing and inefficient installation.

[0080] It should be noted that the difference between the above-mentioned Type A rail vehicle and Type B rail vehicle may be only in the different dimensions of their internal space along the transverse direction of the rail vehicle, or only in the different dimensions of their internal space along the longitudinal direction of the rail vehicle, or may be in both the different dimensions of their internal space along the transverse direction of the rail vehicle and the different dimensions of their internal space along the longitudinal direction of the rail vehicle.

[0081] In this embodiment, friction-increasing textures are provided on the surfaces of the first special-shaped plate group, the second special-shaped plate group, the third special-shaped plate group, the first standard plate group, the second standard plate group and the fourth special-shaped plate group to increase friction and prevent workers from slipping while working inside the vehicle.

[0082] Specifically, patterns can be machined on the working surfaces of the first standard plate 7 , the second standard plate 9 , the first special-shaped plate 10 , the second special-shaped plate 11 , the third special-shaped plate 8 , the fourth special-shaped plate 12 and the fifth special-shaped plate 13 when machining the same.

[0083] In this embodiment, the first, second, third, and fourth shaped plate groups are made of polymer composite engineering plastic. Each of the first standard plate 7, second standard plate 9, first shaped plate 10, second shaped plate 11, third shaped plate 8, fourth shaped plate 12, and fifth shaped plate 13 is manufactured by injection molding.

[0084] Polymer composite engineering plastics are acid and alkali resistant, scratch-resistant, non-deformable, highly resilient, and have a long service life. They can significantly extend the service life of protective devices used on rail vehicle floor coverings, allowing for reuse across the manufacturing cycle of multiple vehicles, reducing protection costs. Furthermore, their moderate hardness effectively protects the floor covering without damaging it. Polymer composite engineering plastics are also resistant to wear and tear, preventing secondary contamination of the vehicle. Polymer composite engineering plastics also do not generate static electricity, thus avoiding safety incidents caused by static electricity. Polymer composite engineering plastics do not chemically react with the floor covering material, preventing discoloration or softening of the floor covering.

[0085] In this embodiment, the thickness of the first special-shaped plate group, the second special-shaped plate group, the third special-shaped plate group, the first standard plate group, the second standard plate group and the fourth special-shaped plate group is 2 to 5 mm.

[0086] That is, the thickness of the first standard plate 7 , the second standard plate 9 , the first special-shaped plate 10 , the second special-shaped plate 11 , the third special-shaped plate 8 , the fourth special-shaped plate 12 and the fifth special-shaped plate 13 is 2 to 5 mm.

[0087] Specifically, the thickness of the first standard plate 7 , the second standard plate 9 , the first special-shaped plate 10 , the second special-shaped plate 11 , the third special-shaped plate 8 , the fourth special-shaped plate 12 and the fifth special-shaped plate 13 is 3 mm or 4 mm.

[0088] The thickness of the protective device for the floor cloth of a railway vehicle is sufficient to prevent damage to the floor cloth caused by falling sharp objects.

[0089] In summary, the protective device for rail vehicle floor cloth provided by the embodiment of the present invention ensures the protective effect of the floor cloth, and the protection cost is low. During the on-site construction process, there is no need for on-site cutting and filling, which is conducive to improving vehicle production efficiency.

[0090] It should be noted that the shapes and sizes of the various special-shaped plates in the embodiments of the present invention are relative to those of standard plates. Not all special-shaped plates are special-shaped. Some special-shaped plates are rectangular in shape, but their sizes are different from those of standard plates.

[0091] It should be noted that in traditional protection technologies, when corrugated paper is used for protection, the corrugated paper needs to be replaced at least twice during the vehicle manufacturing cycle, and a large amount of tape is required for protection. The protection cost of a single carriage is about 4,400 yuan. When crystal panels are used for protection, the protection cost of a single carriage is about 2,800 yuan. If high-quality brand gray crystal panels are used, the protection cost of a single carriage can reach 4,100 yuan. When floor leather is used for protection, the protection cost of a single carriage is about 2,600 yuan. After adopting the protective device for rail vehicle floor cloth provided by the embodiment of the present invention, since it can be used repeatedly on different vehicles, it is conservatively estimated that, taking 40 times of repeated use as an example, the protection cost of a single carriage is about 900 yuan. In fact, through long-term use, it can be reused 70 to 80 times, and the protection cost of a single carriage is as low as about 500 yuan.

[0092] The protective device for rail vehicle floor cloth provided in this embodiment adopts the form of composite engineering plastic splicing tiles to protect the floor cloth, which greatly reduces the protection cost and achieves greater economic value.

[0093] On the other hand, based on the same general inventive concept, the present invention also provides a method for protecting a rail vehicle floor covering based on the protective device for a rail vehicle floor covering provided in any of the above-described embodiments. The protective method for a rail vehicle floor covering described below and the protective device for a rail vehicle floor covering described above can be referenced in conjunction with each other.

[0094] like Figure 4 As shown, the protection method for rail vehicle floor cloth provided by the embodiment of the present invention includes:

[0095] Step 110: Lay a first special-shaped board group, a first standard board group, a second standard board group, and a fourth special-shaped board group on top of the floor cloth;

[0096] Step 120: Before installing the equipment, remove the first standard plate group and lay the third special-shaped plate group in the equipment installation area outside the projection area of ​​the equipment;

[0097] Step 130: Fix the device in the device installation area;

[0098] Step 140: Before installing the columns, remove the first set of special-shaped plates and lay the second set of special-shaped plates in the central column area outside the projection area of ​​the columns.

[0099] Step 150: Fix the column to the central column area;

[0100] Step 160: After all the processing steps of the rail vehicle are completed, the second special-shaped plate group, the third special-shaped plate group, the second standard plate group, and the fourth special-shaped plate group are removed.

[0101] It can be understood that after the floor cloth is laid inside the rail vehicle, before the rail vehicle enters the final assembly workshop, it is necessary to lay the first special-shaped plate group, the first standard plate group, the second standard plate group and the fourth special-shaped plate group on top of the floor cloth, and use the first special-shaped plate group, the first standard plate group, the second standard plate group and the fourth special-shaped plate group to fully protect the floor cloth.

[0102] When the device 6 needs to be installed, the first standard plate group covering the device installation area 3 is first removed, and then the third special-shaped plate group is laid on the device installation area 3 to expose the target installation position of the device 6, and then the fixed installation operation of the device 6 is performed.

[0103] Accordingly, when the column 5 needs to be installed, the first special-shaped plate group covering the central column area 2 is first removed, and then the second special-shaped plate group is laid on the central column area 2 to expose the target installation position of the column 5, and then the fixed installation operation of the column 5 is performed.

[0104] After all processing steps of the rail vehicle are completed, the second set of special-shaped plates, the third set of special-shaped plates, the second set of standard plates, and the fourth set of special-shaped plates can be removed. The protection method for rail vehicle floor cloth provided by the embodiment of the present invention effectively improves the protection effect of the floor cloth and has a low cost for protecting the floor cloth.

[0105] The derivation process of the beneficial effects of the protection method for rail vehicle floor cloth in the embodiment of the present invention is substantially similar to the derivation process of the beneficial effects of the protection device for rail vehicle floor cloth described above, and thus will not be repeated here.

[0106] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
