[0060] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0061] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0062] As shown in the background technology, in the prior art, the skirt panels of rail vehicles are usually installed on the vehicle body in a hanging manner. When installing the skirt panels, in order not to affect the assembly of other components of the rail vehicle, it is necessary to first fix the skirt panels on the corresponding assembly frame, assemble the skirt panel locks, skirt panel hinges and other components on the skirt panels, and then move the skirt panels to the designated location. Multiple staff members work together to lift the skirt panels to the skirt panel brackets, connect the hinged shaft seats on the skirt panels with the shaft seats, and complete the installation of the skirt panels.

[0063] However, since the skirt board is a large arc-shaped plate, it is difficult for ordinary handling tools to transport the skirt board smoothly. In addition, the skirt board bracket is located at a high position, and the workers often need to lift the skirt board to a height of about two meters, which is labor-intensive and has low installation efficiency. In addition, since the skirt board is pre-installed with multiple parts such as skirt board locks and skirt board folds, these parts may fall during the manual lifting process, causing damage to the parts or even injuring the workers.

[0064] In view of the above technical problems, an embodiment of the present application provides a transport vehicle, including a mobile frame, a driving mechanism and a support seat, wherein the driving mechanism is arranged on the mobile frame, the support seat is connected to the driving mechanism, and the skirt board is fixed on the support portion of the support seat, wherein the shape and structure of the support portion match those of the skirt board, so that the support portion can form a contour protection for the skirt board, and the skirt board only needs to be placed on the support portion to remain stable. After the skirt board is fixed on the support portion, the position of the skirt board can be adjusted by the mobile frame, and the height of the skirt board can be adjusted by driving the support seat to rise and fall by the driving mechanism, and finally the hinge seat on the skirt board is fixed to the shaft seat on the skirt board bracket, and then the skirt board can be hung on the vehicle body. Therefore, the skirt board can be stabilized in a position suitable for hanging only by pushing the mobile bracket and controlling the driving mechanism, and the installation of the skirt board can be completed without the staff having to lift it for a long time, which effectively saves manpower and improves the installation efficiency of the skirt board.

[0065] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings:

[0066] See also Figure 1 and Figure 2As shown, the transport vehicle of the embodiment of the present application includes a moving frame 100, a driving mechanism 200 and a support seat 300; the support seat 300 has at least two support parts 310 matching the skirt board on the rail vehicle, and the support parts 310 are used to fix the skirt board; the driving mechanism 200 is arranged on the moving frame 100, and the support seat 300 and the moving frame 100 are both connected to the driving mechanism 200; the driving mechanism 200 is configured to drive the support seat 300 to rise and fall relative to the moving frame 100, so as to drive the skirt board to rise and fall.

[0067] In the present application, the driving mechanism 200 is fixed on the mobile frame 100, the support seat 300 is connected to the driving mechanism 200, and the skirt board is fixed on the support portion 310 of the support seat 300. The position of the skirt board is adjusted by adjusting the position of the mobile frame 100, and the driving mechanism 200 drives the support seat 300 to rise and fall relative to the mobile frame 100, thereby adjusting the height of the skirt board, and finally making the hinge seat on the skirt board correspond to the shaft seat on the skirt board bracket 244, so that the skirt board can be quickly hung on the skirt board bracket 244. Therefore, it is only necessary to adjust the position of the mobile frame 100 and control the driving mechanism 200, so that the skirt board can be quickly and stably moved to a position suitable for hanging, without the need for staff to lift it for a long time, saving manpower and improving the installation efficiency of the skirt board.

[0068] In addition, by using a transport vehicle to lift the skirt board, workers do not need to stand under the skirt board during the raising and lowering process, thus avoiding the pre-installed parts on the skirt board from falling and injuring the workers, thus protecting the personal safety of the workers.

[0069] Among them, the support seat 300 can be configured to be connected only to the driving mechanism 200. When the driving mechanism 200 drives the support seat 300 to rise and fall, the driving mechanism 200 bears the weight of the skirt plate. It can also be configured to be slidingly connected to the moving frame 100 at the same time, thereby dispersing part of the force on the moving frame 100, saving the driving force of the driving mechanism 200 and improving the stability of the lifting support seat 300. The specific installation method of the support seat 300 is not limited in this application, and it can be driven to rise and fall by the driving mechanism 200.

[0070] Furthermore, the mobile frame 100 can be configured to include a base plate 110, two side plates 120, two support beams 140 and at least three wheels 130. The wheels 130 are installed on the base plate 110. The wheels 130 can be universal wheels to adjust the position of the mobile frame 100. The two side plates 120 are arranged on opposite sides of the base plate 110. The two ends of the two support beams 140 are connected to the two side plates 120 to improve the stability of the mobile frame 100 itself.

[0071] In specific implementation, the moving seat can be set as large as possible to improve the bearing capacity of the moving seat itself and ensure the stability of the transport vehicle and the lifting skirt.

[0072] In some possible implementations, see Figure 1 and Figure 2 As shown, the support portion 310 of the embodiment of the present application is a support plate provided with an arc-shaped protrusion 311, and the arc-shaped protrusion 311 is used to fix the skirt board, and the curvature of the arc-shaped protrusion 311 matches the curvature of the skirt board.

[0073] In some embodiments, an arc-shaped protrusion 311 is provided at one end of the support plate away from the bottom plate 110 of the movable frame 100, and the curvature of the arc-shaped protrusion 311 is consistent with the curvature of the skirt board. In this way, the skirt board can be placed on the arc-shaped protrusion 311 to maintain stability without adding additional fixing devices. The structure is simple and easy to operate, which is conducive to improving the installation efficiency of the skirt board.

[0074] In addition, by placing the skirt board on the arc-shaped protrusion 311 and lifting it, the concave surface of the skirt board can face downward when the skirt board rises to the specified height, so that the hinge shaft seat of the skirt board is connected with the shaft seat on the skirt board bracket 244, and the skirt board can be directly hung on the vehicle body without turning the skirt board over again, which makes the operation more convenient, thereby further saving manpower and improving installation efficiency.

[0075] In some possible implementations, see Figure 1 and Figure 2 As shown, the support seat 300 of the embodiment of the present application has a connecting portion 320; the connecting portion 320 is connected to the driving mechanism 200, the supporting portion 310 is vertically arranged on the connecting portion 320, and the supporting portion 310 is slidably connected to the side wall of the moving frame 100.

[0076] In a specific implementation, in order to ensure the stability of the support seat 300, the distance between the support portions 310 located at the opposite ends of the connecting portion 320 needs to be as large as possible, so at least two support portions 310 are symmetrically arranged at the two ends of the connecting portion 320. The specific number of the support portions 310 is not limited in this application. When the number of support portions 310 is greater than two, other support portions 310 can be arranged between the two support portions 310 located at the ends to strengthen the supporting force.

[0077] In addition, in order to increase the distance between the support parts 310 at both ends, the size of the connecting part 320 needs to be set as large as possible. Therefore, the connecting part 320 is set to be slightly smaller than the length of the bottom plate 110 of the moving frame 100, so that the support parts 310 at both ends of the connecting part 320 can contact the two side plates 120 respectively, thereby improving the stability of its supporting skirt plate.

[0078] In addition, in order to reduce the driving force required by the driving mechanism 200, the support part 310 can be slidably connected to the side plate 120 of the moving frame 100, so that part of the force can be dispersed to the moving frame 100, and it can also play a guiding role, so that the support part 310 can always slide up and down along the side plate 120 under the drive of the driving mechanism 200 to avoid displacement.

[0079] In some possible implementations, see Figure 1 and Figure 3 As shown, the embodiment of the present application also includes at least two slide rails 400 and at least two sliders 500; the slide rails 400 are arranged on the side walls of the moving frame 100, and the sliders 500 are arranged on the support part 310, and the sliders 500 are slidably connected to the slide rails 400 so that the support part 310 slides along the side walls of the moving frame 100.

[0080] It can be understood that the slide rail 400 can be set on the side plate 120 of the moving frame 100, and the slider 500 can be fixed on the support part 310. When the support seat 300 is driven by the driving mechanism 200 to be raised or lowered relative to the moving frame 100, the slider 500 on the support part 310 slides relative to the slide rail 400, thereby limiting the moving path of the support part 310 and avoiding displacement of the support seat 300 during the process of lifting the support seat 300, thereby improving the safety of the use of the transport vehicle.

[0081] In some possible implementations, see Figure 1 , Figure 4 and Figure 5 As shown, a guide post 410 is provided on the slide rail 400 of the embodiment of the present application, and a slide groove 510 is provided on the slider 500; a portion of the guide post 410 is located in the slide groove 510 and is slidably connected to the slide groove 510.

[0082] In a specific implementation, a guide column 410 can be set on the slide rail 400, and a slide groove 510 can be opened on the slider 500. The slide groove 510 matches the shape of the guide column 410, and part of the guide column 410 is located in the slide groove 510. The notch of the slide groove 510 is set to be smaller than the diameter of the guide column 410. This can prevent the guide column 410 from detaching from the slide groove 510, thereby further improving the stability of the lifting and lowering of the support seat 300.

[0083] In some possible implementations, see Figure 1 , Figure 2 and Figure 3As shown, the driving mechanism 200 of the embodiment of the present application includes a mounting seat 210, a screw rod 220, a tray 230 and a driving assembly 240; a mounting platform 600 is arranged on the mobile frame 100, and a mounting hole 610 is opened on the mounting platform 600; the mounting seat 210 is fixedly connected to the mounting platform 600, the screw rod 220 passes through the mounting hole 610 and the mounting seat 210 in sequence and is connected to the tray 230, and the tray 230 is connected to the support seat 300; the screw rod 220 is spirally connected to the mounting seat 210, and the driving assembly 240 is arranged on the mounting seat 210; the driving assembly 240 is configured to drive the screw rod 220 to rotate relative to the mounting seat 210 to drive the tray 230 to rise and fall relative to the mobile frame 100.

[0084] It should be noted that the screw 220 is spirally connected to the mounting seat 210, the screw 220 is rotatably connected to the tray 230, and the tray 230 is fixedly connected to the connecting portion 320 of the support seat 300. The driving assembly 240 can make the screw 220 rotate relative to the mounting seat 210, so that the screw 220 can move up and down relative to the mounting platform 600, and drive the tray 230 to rise and fall relative to the moving frame 100, and the tray 230 drives the support seat 300 to rise and fall, thereby adjusting the height of the skirt board.

[0085] To ensure that the screw rod 220 has space to move up and down relative to the mounting platform 600 , a larger gap needs to be maintained between the mounting platform 600 and the bottom plate 110 so that the screw rod 220 can descend relative to the mounting platform 600 .

[0086] Among them, the driving component 240 can be set as an electric structure, using a motor to drive the screw 220 to rotate, further saving manpower, or it can be set as a manual drive structure. Its specific structure is not limited in this embodiment, and it can drive the screw 220 to rotate relative to the mounting base 210.

[0087] In some possible implementations, see Figure 1 , Figure 2 and Figure 3 As shown, the driving component 240 of the embodiment of the present application includes a driving member 241, an extension rod 242 and a handwheel 243; the driving member 241 is arranged on the mounting base 210, one end of the extension rod 242 is connected to the driving member 241, and the other end of the extension rod 242 extends out of the moving frame 100 and is connected to the handwheel 243; the handwheel 243 drives the driving member 241 to rotate through the extension rod 242 to drive the screw 220 to rotate.

[0088] In some embodiments, the driving member 241 is disposed on the mounting base 210, and the screw 220 can be driven to rotate by rotating the driving member 241. However, since the overall volume of the mobile frame 100 is relatively large, in order to facilitate the operation of the staff, an extension rod 242 needs to be provided, and the two ends of the extension rod 242 are respectively connected to the driving member 241 and the handwheel 243. In this way, the handwheel 243 can be disposed on the outside of the mobile frame 100, and the driving member 241 can be driven to rotate through the extension rod 242 by simply rotating the handwheel 243, thereby driving the screw 220 to rotate, thereby realizing the lifting and lowering of the tray 230.

[0089] In some possible implementations, see Figure 1 , Figure 2 and Figure 3 As shown, the driving assembly 240 of the embodiment of the present application further includes a bracket 244 ; the bracket 244 is fixedly connected to the mounting platform 600 , and the extension rod 242 is rotatably connected to the bracket 244 .

[0090] It is understandable that the extension rod 242 itself is relatively long and is prone to breakage if it is completely suspended in the air. Therefore, a bracket 244 is set on the mounting platform 600, and the extension rod 242 is rotatably connected to the bracket 244. The bracket 244 supports the extension rod 242 and does not affect the rotation of the extension rod 242, thereby ensuring the service life of the drive assembly 240.

[0091] In some possible implementations, see Figure 1 , Figure 2 and Figure 3 As shown, arc-shaped grooves 121 are provided on two opposite side walls of the moving frame 100 of the embodiment of the present application; the opening of the arc-shaped groove 121 is away from the moving frame 100 and is used to fix the skirt board, and the arc-shaped groove 121 matches the shape of the skirt board.

[0092] Specifically, the arc groove 121 is provided on the side plate 120 of the mobile frame 100. Since the skirt plate assembly work such as installing the skirt plate lock, skirt plate hinge and other parts on the skirt plate needs to be performed on the concave surface of the skirt plate, and when the skirt plate is placed on the support plate, the concave surface of the skirt plate faces the bottom plate 110, the arc groove 121 is provided on the side plate 120, so that the transport vehicle plays the role of the skirt plate assembly bracket 244. When assembling the skirt plate, it can be placed on the arc groove 121, and the matching of the arc groove 121 and the skirt plate shape can ensure the stability of the skirt plate.

[0093] In this way, the functions of assembling, transporting and lifting can be integrated into the transport vehicle, thereby improving the applicability of the transport vehicle and further shortening the entire installation period of the skirt board.

[0094] In some possible implementations, see Figure 1 , Figure 2 and Figure 3As shown, the embodiment of the present application also includes at least two limiting beams 700; the limiting beams 700 are arranged between the side wall of the moving frame 100 and the support part 310, the limiting beams 700 are fixedly connected to the moving frame 100, and abut against the support part 310; the extension direction of the limiting beams 700 is perpendicular to the moving direction of the support part 310.

[0095] It can be understood that the support part 310 is slidably connected to the side plate 120 of the mobile frame 100 through the slide rail 400 and the slider 500, so a certain distance is maintained between the support part 310 and the side plate 120, and a limiting beam 700 is set between the support part 310 and the side plate 120, and the width of the limiting beam 700 is exactly equal to the distance between the support part 310 and the side plate 120. This can prevent the support seat 300 from being deformed or shifted when moving relative to the mobile bracket 244, thereby further improving the stability of the support seat 300 in lifting and lowering.

[0096] In summary, the transport vehicle provided by the present application includes a mobile frame 100, a driving mechanism 200 and a support seat 300. The support seat 300 is provided with two support parts 310. The support parts 310 have an arc-shaped protrusion 311 that matches the shape of the skirt board. The side plate 120 of the mobile frame 100 has an arc-shaped groove 121 that matches the shape of the skirt board. In actual use, the skirt board is first placed on the arc-shaped groove 121, and the staff pre-installs the skirt board lock, skirt board folding and other components on the skirt board. After the assembly is completed, the skirt board is turned over to place it on the arc-shaped protrusion 311, and then the mobile frame 100 is pushed to the specified position, and the driving mechanism 200 drives the support seat 300 to rise and fall, adjusts the height of the skirt board, and stabilizes the skirt board in a position that is convenient for hanging, and then the hanging operation can be performed. In this way, the assembly, transportation and lifting of the skirt board can be completed quickly, effectively shortening the installation period of the skirt board, saving manpower, reducing labor intensity, and improving the installation efficiency of the skirt board.
