Technical Field

[0001] This application relates to the field of rail passenger vehicle manufacturing and processing technology, specifically to a device and system for painting, puttingtying, sanding and repairing the front of a rail vehicle. Background Technology

[0002] During the production of the train body, workers typically need to rely on a lifting platform to perform painting operations such as applying putty, sanding, painting, and repairs on the train's front. However, because the design of the train's front incorporates multiple considerations of aerodynamics, structural mechanics, aesthetics, safety, and practicality, resulting in a streamlined structure, even with the use of a lifting platform, workers may still be too far from the front, exceeding their working range. This causes inconvenience for the painting work, makes it impossible to ensure the smooth and high-quality completion of the painting work, and poses significant safety hazards.

[0003] Based on the above-mentioned technical problems, those skilled in the art urgently need to develop a device for painting, puttingtying, sanding and repairing the front of a railcar. Summary of the Invention

[0004] This application provides a device and system for painting, puttingtying, sanding and repairing the front of a railcar, which effectively extends the range of the operator's work platform laterally, making the painting operation of the railcar front more convenient and efficient, greatly improving the quality and efficiency of the operation, and enhancing safety.

[0005] Firstly, this application provides a device for painting, puttingtying, sanding, and repairing the front of a railcar, which is connected to a lifting work platform.

[0006] Work platform;

[0007] A connecting structure is fixed to the working platform and is also used for detachable connection to the lifting platform.

[0008] The working platform is connected to the lifting platform via the connecting structure to fill the distance between the lifting platform and the vehicle head.

[0009] In one embodiment, the connection structure includes:

[0010] The first buckle plate is connected to the side of the working platform near the lifting platform and extends along the length of the working platform.

[0011] The second buckle plate is connected to the side of the first buckle plate away from the lifting platform;

[0012] Furthermore, the second buckle plate extends toward the lower surface of the work platform, and the second buckle plate, the first buckle plate, and the work platform constitute a buckle groove.

[0013] In one embodiment, it further includes: a structural reinforcement member disposed on the lower surface of the work platform, used to cooperate with the connection structure to increase the connection strength between the work platform and the lifting work platform.

[0014] In one embodiment, the structural reinforcement includes: a bracket, the number of which is set to at least two, disposed on the lower surface of the work platform;

[0015] The working platform, together with the at least two supports, forms a triangular structure. Moreover, when the working platform is connected to the lifting platform through the connecting structure, at least one of the supports is attached to the lifting platform.

[0016] In one embodiment, the second buckle plate, the first buckle plate, and the at least one bracket attached to the lifting platform constitute a slot.

[0017] In one embodiment, it further includes: a guardrail disposed on the upper surface of the work platform away from the lifting work platform and the side of the vehicle front.

[0018] Secondly, this application provides a system for painting, puttying, sanding, and repairing the front of a railcar, including:

[0019] The lifting platform extends along the length of the railcar and is used to adjust the height of the worker's position by lifting.

[0020] The aforementioned equipment for painting and puttying, sanding, and repairing the front of the railcar;

[0021] The working platform is connected to the lifting platform via the connecting structure to fill the distance between the lifting platform and the vehicle head.

[0022] In one embodiment, the lifting platform includes: a mating plate disposed on the side of the lifting platform near the railcar, wherein the upper surface of the mating plate is higher than the lifting platform, and the mating plate extends along the length direction of the lifting platform;

[0023] The mating plate works with the slot to allow the working platform to fill the distance between the lifting platform and the vehicle head by connecting to the lifting platform.

[0024] Therefore, the working platform of the painting and putty scraping, sanding and repair device of the railcar head can be stably connected to the side of the lifting work platform near the car body (car head) through the above-mentioned connection structure, which effectively extends the range of the workers' working platform laterally.

[0034] Example 1:

[0035] When performing painting operations such as puttying, sanding, painting, and repair on the surface of railcars (including but not limited to: trains, EMUs, locomotives, maglev trains, and suspension trains), the lifting platform is used to support and adjust the height of the workers to adapt to the height of the car body. Furthermore, this lifting platform extends along the length of the car body. Therefore, workers can use this lifting platform to perform painting operations such as puttying, sanding, painting, and repair on the car body.

[0036] However, due to the streamlined structure of the front of the railcar, even when the lifting platform is used, there are still situations where the lifting platform is too far from the front of the car, exceeding the workers' working range. This makes it difficult to carry out painting work such as puttying, sanding, painting, and repairs on the front of the car, causing inconvenience to the painting work and making it impossible to ensure the smooth and high-quality completion of the painting work, and also posing a great safety hazard.

[0037] Therefore, in this embodiment, according to Figure 1-3As shown, this embodiment provides a system for painting, puttingtying, sanding and repairing the front of a railcar, which includes: a device for painting, puttingtying, sanding and repairing the front of the railcar and a lifting work platform.

[0038] The front paint and putty scraping, sanding and repair device of the railcar is detachably and fixedly connected to the lifting platform. Moreover, the front paint and putty scraping, sanding and repair device of the railcar is located between the lifting platform and the front of the railcar to fill the distance between the lifting platform and the front of the railcar.

[0039] The device for painting, sanding, and repairing the front of the railcar includes: a working platform 1; a connecting structure 2 fixed to the working platform 1, and the connecting structure 2 is used for detachable connection to the lifting platform; the working platform 1 is connected to the lifting platform through the connecting structure 2 to fill the distance between the lifting platform and the front of the railcar.

[0040] Specifically, the painting, puttying, sanding and repair device for the front of the railcar includes: a working platform 1 and a connecting structure 2.

[0041] The connecting structure 2 is disposed between the working platform 1 and the lifting platform. The connecting structure 2 is fixed to the working platform 1. Moreover, during the aforementioned painting operations, the connecting structure 2 is detachably connected to the lifting platform. That is, during the aforementioned painting operations, the working platform 1 is connected to the lifting platform through the connecting structure 2 to fill the distance between the lifting platform and the car head. This allows the car head painting and putty scraping, sanding, and repair device of the railcar to be connected to the lifting platform through the connecting structure 2 to fill the distance between the lifting platform and the car head. Of course, when the aforementioned painting operations are not being performed, the working platform 1 can also be removed from the lifting platform through the connecting structure 2. That is, when the aforementioned painting operations are not being performed, the car head painting and putty scraping, sanding, and repair device of the railcar can be removed from the lifting platform based on the connecting structure 2.

[0042] In this embodiment, during the aforementioned painting operations, the work platform 1 is positioned between the lifting platform and the vehicle front via the connecting structure 2, allowing workers to stand on the work platform 1 to perform the painting operations. To further adapt to the vehicle front, based on the above embodiments, another embodiment further incorporates the following configuration: from the direction of the vehicle front to the rear, the width of the work platform 1 gradually decreases in the distance between the lifting platform and the vehicle front; that is, from the direction of the vehicle front to the rear, the width of the work platform 1 gradually decreases, thereby better adapting to the shape of the vehicle front. Alternatively, the shape of the side of the work platform 1 closest to the vehicle front is adapted to the shape of the vehicle front, further enhancing the adaptation to the vehicle front shape.

[0043] Therefore, the working platform 1 of the painting and putty scraping, sanding and repair device of the railcar head can be stably connected to the side of the lifting work platform near the car body (car head) through the above-mentioned connecting structure 2, which effectively extends the working platform range of the workers laterally, making the painting operations such as putty scraping, sanding, painting and repair of the railcar head more convenient and efficient, greatly improving the quality and efficiency of the work, and improving safety.

[0044] Example 2:

[0045] according to Figure 1-3 As shown, during the aforementioned painting operations, the work platform 1 is detachably connected to the lifting platform via the connecting structure 2. This means that during the painting operations, the work platform 1 can be connected to the lifting platform via the connecting structure 2 to fill the distance between the lifting platform and the car head, thus enabling the car head painting and putty scraping, sanding, and repair device to be connected to the lifting platform via the connecting structure 2 to fill the distance between the lifting platform and the car head. Conversely, when the aforementioned painting operations are not being performed, the work platform 1 can also be detached from the lifting platform via the connecting structure 2. That is, when the aforementioned painting operations are not being performed, the car head painting and putty scraping, sanding, and repair device can be detached from the lifting platform based on the connecting structure 2. In other words, the connecting structure 2 is a detachable fixed connection structure. In the above embodiments, the specific structure of the connecting structure 2 is not limited, as long as it meets the requirements of this embodiment. For example, the structural form of the connecting structure 2 can be selected from one or more of the following, including but not limited to: flange connection, threaded connection, socket connection, and snap-fit ​​connection. Of course, when choosing any structural form of connection structure 2, the corresponding structural settings can be made as needed, as long as they can meet the requirements of this embodiment.

[0046] In addition, a mating plate 5 is provided on the aforementioned lifting platform. The mating plate 5 is located on the side of the lifting platform near the railcar. Moreover, the upper surface of the mating plate 5 is higher than the lifting platform, and the mating plate 5 extends along the length of the lifting platform.

[0047] Based on this, and to elaborate on the solution of this embodiment, this second embodiment provides an exemplary description of the connection structure 2 described above, based on the description of any of the above embodiments:

[0048] The connection structure 2 includes: a first buckle plate 21 and a second buckle plate 22;

[0049] The first buckle plate 21 is connected to the side of the work platform 1 near the lifting platform and extends along the length of the work platform 1.

[0050] The second latching plate 22 is connected to the side of the first latching plate 21 away from the lifting platform, and the second latching plate 22 extends toward the lower surface of the working platform 1. The second latching plate 22, the first latching plate 21, and the working platform 1 constitute a latching groove 23. Preferably, the first latching plate 21 and the second latching plate 22 are integrally formed.

[0051] The slot 23 is adapted to the mating plate 5 involved in the lifting work platform, that is, the work platform 1 is detachably connected to the lifting work platform by inserting the mating plate 5 into the slot 23.

[0052] During the aforementioned painting operations, the work platform 1 connects to the lifting platform by engaging the slot 23 onto the mating plate 5. Since the mating plate 5 is located on the side of the lifting platform near the railcar, the work platform 1 fills the distance between the lifting platform and the railcar head. This allows the railcar head painting and putty application, sanding, and repair device to be connected to the lifting platform via the engagement of the slot 23 and the mating plate 5, thus filling the gap between the lifting platform and the railcar head. Alternatively, when the aforementioned painting operations are not being performed, the work platform 1 can be removed from the lifting platform by disassembling the slot 23 and the mating plate 5. In other words, when the aforementioned painting operations are not being performed, the railcar head painting and putty application, sanding, and repair device can be removed from the lifting platform by disassembling the slot 23 and the mating plate 5.

[0053] Therefore, the working platform 1 of the painting and putty scraping, sanding and repair device of the railcar head can be firmly locked to the side of the lifting work platform near the car body (car head) through the buckle structure formed by the slot 23 and the mating plate 5. This effectively extends the range of the workers' working platform laterally, making the painting operations such as putty scraping, sanding, painting and repair of the railcar head more convenient and efficient, greatly improving the quality and efficiency of the work, and improving safety.

[0054] Furthermore, based on any of the above embodiments, the following further configuration is made for the snap-fit ​​structure formed by the slot 23 and the mating plate 5:

[0055] Multiple mating plates 5 are arranged sequentially on the lifting platform along its height direction. Thus, the lifting operation of the platform allows for primary height adjustment of the railcar's front painting and putty scraping, sanding, and repair device (working platform 1). Furthermore, by connecting the device to mating plates 5 at different heights, secondary height adjustment is achieved. This provides versatility in height adjustment, better adapting to the railcar's height and making painting operations such as putty application, sanding, painting, and repair on the railcar's front more convenient and efficient, significantly improving work quality and efficiency, and enhancing safety.

[0056] Example 3:

[0057] according to Figure 1-3 As shown, the working platform 1 of the paint and putty scraping, sanding and repair device of the railcar head is connected to the side of the lifting work platform near the car body (car head) through the snap-fit ​​structure formed by the slot 23 and the mating plate 5, which effectively extends the range of the worker's working platform laterally. The worker performs the above-mentioned painting operations on the lifting work platform and within the working range extended by the working platform 1.

[0058] To further improve the structural strength of the working platform 1, which is secured to the lifting platform by the snap-fit ​​structure formed by the slot 23 and the mating plate 5, the following settings are made in this embodiment based on any of the above embodiments:

[0059] The painting, puttying, sanding, and repair device for the front of the railcar is also equipped with a structural reinforcement 3. This structural reinforcement 3 is located on the lower surface of the work platform 1 and is used to cooperate with the connecting structure 2 to increase the connection strength between the work platform 1 and the lifting platform. Specifically, the structural reinforcement 3 is located on the lower surface of the work platform 1 and is used to cooperate with the snap-fit ​​structure formed by the slot 23 and the mating plate 5 to increase the connection strength between the work platform 1 and the lifting platform.

[0060] One option for the structural reinforcement 3 is:

[0061] The structural reinforcement 3 is configured as a reinforcing rib structure, specifically including: a bracket 31, wherein the number of brackets 31 is set to at least two, and both are disposed on the lower surface of the work platform 1; moreover, the work platform 1 and the at least two brackets 31 form a triangular structure (e.g., Figure 1-3 As shown: it has an inverted triangular structure), and when the work platform 1 is connected to the lifting work platform through the connecting structure 2, at least one bracket 31 is attached to the lifting work platform.

[0062] The triangular structure formed by the working platform 1 and at least two supports 31 (at least one support 31 is attached to the lifting platform) (e.g.) Figure 1-3 As shown (inverted triangular structure), it can greatly increase the connection strength between the working platform 1 and the lifting platform, thereby better adapting to the height of the car head. This further makes the painting operations such as puttying, sanding, painting and repair of the car head of the railcar more convenient and efficient, greatly improving the quality and efficiency of the work, and improving safety.

[0063] In addition, in each structural reinforcement 3, the triangular structure formed by the working platform 1 and at least two supports 31 (at least one support 31 is attached to the lifting work platform) can also be configured as follows: an additional support 31 is provided on the lower surface of the working platform 1, and the support 31 forms a triangular structure with the above-mentioned at least two supports 31.

[0064] In addition, based on any of the above embodiments, the following settings can be made: the number of the above-mentioned structural reinforcement 3 can be set to multiple, and these structural reinforcement 3 are arranged along the length direction of the vehicle body on the lower surface of the work platform 1, thereby further increasing the connection strength between the work platform 1 and the lifting work platform, so as to better adapt to the height of the car head, and further make the painting operations such as puttying, sanding, painting and repair of the car head of the railcar more convenient and efficient, greatly improving the quality and efficiency of the operation, and improving safety.

[0065] Furthermore, based on any of the above embodiments, the following configuration can also be made: the second latching plate 22, the first latching plate 21, and the at least one bracket 31 attached to the lifting platform can also constitute the aforementioned slot 23. Specifically, because the bracket 31 is disposed on the lower surface of the working platform 1, based on the second latching plate 22, the first latching plate 21, and the working platform 1 forming the slot 23, the at least one bracket 31 attached to the lifting platform further effectively increases the depth of the slot 23 in conjunction with the second latching plate 22 and the first latching plate 21, thereby improving the connection strength between the slot 23 and the mating plate 5, and further increasing the connection strength between the working platform 1 and the lifting platform. This allows for better adaptation to the height of the train head, and further makes the painting operations such as puttying, sanding, painting, and repair of the train head more convenient and efficient, greatly improving the quality and efficiency of the work, and enhancing safety.

[0066] In addition, based on any of the above embodiments, the following settings can also be made: the paint and putty scraping, sanding and repair device for the front of the railcar is also equipped with a guardrail 4, which is set on the upper surface of the work platform 1 away from the lifting work platform and the side of the front of the car, thereby providing safety protection for the workers and improving safety.

[0067] Of course, the guardrail 4 can be rotated to the work platform 1 so that workers can enter and exit the work platform 1.

[0068] Example 4:

[0069] according to Figure 1-3 As shown, this embodiment provides a system for painting, puttingtying, sanding and repairing the front of a railcar, including: a device for painting, puttingtying, sanding and repairing the front of a railcar and a lifting work platform.

[0070] A mating plate 5 is provided on the lifting platform. The mating plate 5 is located on the side of the lifting platform near the railcar. Moreover, the upper surface of the mating plate 5 is higher than the lifting platform, and the mating plate 5 extends along the length of the lifting platform.

[0071] The device for painting, sanding and repairing the front of the railcar includes: a working platform 1, a first buckle plate 21, a second buckle plate 22, four structural reinforcements 3 set on the lower surface of the working platform 1, and a guardrail 4.

[0072] The second buckle plate 22, the first buckle plate 21, and the working platform 1 together form the buckle slot 23.

[0073] according to Figure 1-3As shown, each structural reinforcement 3 includes two supports 31 -- a first support 311, a second support 312, and a third support 313. The third support 313 is fixed to the lower surface of the work platform. The first support 311, the second support 312, and the third support 313 are connected end to end to form an inverted triangular structure. Moreover, the first support 311 is attached to the lifting work platform.

[0074] The guardrail 4 is installed on the upper surface of the work platform 1 away from the lifting platform and the side of the vehicle front, thereby providing safety protection for the workers and improving safety.

[0075] The slot 23 is adapted to the mating plate 5 in the lifting platform. That is, by inserting the mating plate 5 into the slot 23, the work platform 1 slot 23 is attached and anchored to the lifting platform. In other words, by inserting the mating plate 5 into the slot 23, the work platform 1 is detachably connected to the lifting platform.

[0076] The working platform 1 of the railcar's front painting and putty scraping, sanding, and repair device can be securely fastened to the side of the lifting work platform near the car body (front) via a snap-fit ​​structure consisting of a slot 23 and a mating plate 5. This effectively extends the range of the workers' work platform laterally, making painting operations such as putty scraping, sanding, paint spraying, and repair of the railcar's front more convenient and efficient, significantly improving work quality and efficiency, and enhancing safety. When not performing the aforementioned painting operations, the railcar's front painting and putty scraping, sanding, and repair device can also be easily removed from the lifting work platform by disassembling the slot 23 and the mating plate 5.
