DETAILED DESCRIPTION

[0048] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0049] As Figures 1 to 10As shown, a first aspect of the present invention provides a floor laying device, including a movable rod 400, a pull rod 408, and an adjusting assembly 410; wherein, a first end of the movable rod 400 is connected to a seat fixing hole 406 on at least one of a first floor 402 to be laid and a second floor 404 to be laid; a first end of the pull rod 408 is hinged to a second end of the movable rod 400; a first end of the adjusting assembly 410 is connected to the seat fixing hole 406 on at least another of the first floor 402 to be laid and the second end of the adjusting assembly 410 is connected to a second end of the pull rod 408, and the adjusting assembly 410 is adapted to adjust the relative distance between the first floor 402 to be laid and the second floor 404 to be laid along the direction of the pull rod 408.

[0050] According to the first aspect of the present invention, the floor laying device provides a movable rod 400 on a seat fixing hole 406 on at least one of the first floor 402 and the second floor 404 to be laid, and an adjustment component 410 is fixed on the seat fixing hole 406 on at least the other of the first floor 402 and the second floor 404 to be laid. This not only allows for the positioning of the movable rod 400 and the adjustment component 410 through the seat fixing hole 406, but also provides corresponding force application points for the movable rod 400 and the adjustment component 410, thus facilitating the laying of the floor. The adjustment of the first flooring 402 and the second flooring 404 to be laid is achieved by connecting the pull rod 408 to the adjustment assembly 410. This allows the adjustment assembly 410 to adjust the distance between the first flooring 402 and the second flooring 404. Furthermore, because the pull rod 408 is hinged to the movable rod 400, the adjustment of the first and second flooring can still be achieved even when the line connecting the seat fixing holes 406 on the first flooring and the seat fixing holes 406 on the second flooring is not parallel to the pulling direction of the adjustment assembly 410. Additionally, when the flooring installation device is not needed, the pull rod 408 can be folded for storage and portability.

[0051] Please continue reading Figures 1 to 10 In this embodiment of the invention, seat fixing holes 406 are formed on both the first floor 402 and the second floor 404 to be laid, and the seat fixing holes 406 are used to install seats. Figure 8 For example, multiple seat fixing holes 406 for installing seats are provided on the first floor 402 to be laid. Similarly, multiple seat fixing holes 406 for installing seats are also provided on the second floor 404 to be laid.

[0052] In the embodiment of the present application, the first to-be-laid floor 402 and the second to-be-laid floor 404 can be the passenger compartment floor of a rail vehicle, and in the actual installation process, the first to-be-laid floor 402 and the second to-be-laid floor 404 need to be laid and aligned along the vehicle length direction of the rail vehicle.

[0053] For example, in the embodiment of the present application, the movable rod 400 can be arranged on the first to-be-laid floor 402, and the first end of the movable rod 400 is fixedly connected to the seat fixing hole 406 on the first to-be-laid floor 402. It can be understood that the first end of the movable rod 400 mentioned here refers to the end of the movable rod 400 connected to the nut seat 413.

[0054] Referring to Figure 6 , the movable rod 400 includes a first movable support rod 412 and a second movable support rod 414, wherein the first end of the second movable support rod 414 is hinged to the first end of the first movable support rod 412, and the second end of the second movable support rod 414 and the second end of the first movable support rod 412 are connected to the seat fixing hole 406 through the nut seat 413.

[0055] In the embodiment of the present application, the nut seat 413 can be installed in the seat fixing hole 406 through threaded connection, and the second end of the first movable support rod 412 and the second end of the second movable support rod 414 are connected to the nut seat 413. By such arrangement, a stable triangular structure is formed between the first movable support rod 412, the second movable support rod 414 and the nut seat 413. That is, a stable three-point support is formed between the hinge point of the first end of the first movable support rod 412 and the first end of the second movable support rod 414, the connection point of the first movable support rod 412 and the nut seat 413, and the connection point of the second movable support rod and the nut seat 413.

[0056] In other embodiments, the movable rod 400 can also be arranged on the second to-be-laid floor 404, or the movable rod 400 can be arranged on both the first to-be-laid floor 402 and the second to-be-laid floor 404.

[0057] Referring to Figure 9 and Figure 10 In the preferred embodiment, the movable rod 400 is arranged on both the first to-be-laid floor 402 and the second to-be-laid floor 404, and by such arrangement, even if there is a certain deviation in the vehicle width direction of the first to-be-laid floor 402 and the second to-be-laid floor 404, the adjustment of the distance between the first to-be-laid floor 402 and the second to-be-laid floor 404 can be realized through the adjustment of the movable rod 400.

[0058] The first end of the pull rod 408 is hinged to the second end of the movable rod 400, and it can be understood that the second end of the movable rod 400 refers to an end of the movable rod 400 away from the connection between the movable rod 400 and the nut seat 413, and the first end of the pull rod 408 refers to an end of the pull rod 408 hinged to the movable rod 400.

[0059] In the embodiment of the present application, referring to Figure 9 and Figure 10 , the pull rod 408 is two groups, and the first ends of the two groups of pull rods 408 are respectively hinged to the second ends of the two groups of movable rods 400.

[0060] An adjustment assembly 410 is arranged between the two groups of pull rods 408, and when the adjustment assembly 410 is actuated, the adjustment assembly 410 can make the first and second to-be-laid floors 402 and 404 approach or move away from each other along the length direction of the rail vehicle.

[0061] Referring to Figure 7 , according to an embodiment of the present application, the adjustment assembly 410 includes a fixed rail 416 and a movable rail 418; the fixed rail 416 is connected to one of the first and second to-be-laid floors 402 and 404; and the movable rail 418 is adapted to be connected to the other of the first and second to-be-laid floors 402 and 404 through the pull rod 408.

[0062] In the embodiment of the present application, the adjustment assembly 410 includes the slidingly matched fixed rail 416 and movable rail 418, and through the sliding matching of the fixed rail 416 and the movable rail 418, the movement direction of the adjustment assembly 410 can be guided, thereby improving the movement accuracy when the first and second to-be-laid floors 402 and 404 move relatively.

[0063] For example, the fixed rail 416 can be connected to the first to-be-laid floor 402, and the movable rail 418 can be connected to the second to-be-laid floor 404 through the pull rod 408, so that when the first and second to-be-laid floors 402 and 404 move relatively under the driving of the adjustment assembly 410, the second to-be-laid floor 404 can move relatively along the direction of the movable rail 418 and the fixed rail 416 under the guidance of the movable rail 418 and the fixed rail 416. As described above, since the pull rod 408 is two groups, the fixed rail 416 can also be connected to the first to-be-laid floor 402 through the pull rod 408.

[0064] Of course, in some other embodiments, the fixed rail 416 can be connected with the second to-be-laid floor 404 through the pull rod 408, and the movable rail 418 can be connected with the first to-be-laid floor 402 through the pull rod 408. It can be understood that, in the embodiments of the present application, the moving precision in the relative movement of the two to-be-laid floors can be improved by connecting the movable rail 418 with one of the to-be-laid floors through the pull rod 408 and connecting the fixed rail 416 with the other to-be-laid floor through the pull rod 408.

[0065] According to an embodiment of the present application, the adjusting assembly 410 further comprises a guide frame 420 connected between the fixed rail 416 and the movable rail 418.

[0066] Referring to Figure 7 In the embodiments of the present application, in order to further improve the guiding precision between the fixed rail 416 and the movable rail 418, a guide frame 420 is further arranged between the fixed rail 416 and the movable rail 418. The guide frame 420 can be one, which can be mounted on any one of the fixed rail 416 and the movable rail 418, and a corresponding guiding structure is arranged on the other one of the fixed rail 416 and the movable rail 418. Of course, the guide frame 420 can also be two, which are respectively mounted on the fixed rail 416 and the movable rail 418.

[0067] For example, the guide frame 420 can be formed with a corresponding guide rail structure, and the guiding structure can be formed with a clamping structure which is slidingly guided and matched with the guide rail structure, so that the guiding effect of the fixed rail 416 and the movable rail 418 can be effectively achieved.

[0068] According to an embodiment of the present application, the adjusting assembly 410 further comprises a driving mechanism 422 adapted to drive the movable rail 418 to move relative to the fixed rail 416 to adjust the relative distance between the first to-be-laid floor 402 and the second to-be-laid floor 404.

[0069] As described above, in order to drive the movable rail 418 to move relative to the fixed rail 416 to change the relative distance between the first to-be-laid floor 402 and the second to-be-laid floor 404, the adjusting assembly 410 further comprises a driving mechanism 422. It should be noted that, in the embodiments of the present application, the driving mechanism 422 can adopt various forms such as manual driving, electric driving, hydraulic driving, oil pressure driving, etc., as long as the above functions can be achieved.

[0070] According to one embodiment of the present application, the driving mechanism 422 comprises a driving shaft 424 and a driven shaft 428; the axis of the driving shaft 424 is perpendicular to the moving direction of the moving rail 418, the driving shaft 424 is rotatably connected to one of the fixed rail 416 and the moving rail 418, and the driving shaft 424 is connected with a driving gear 426; the axis of the driven shaft 428 is parallel to the moving direction of the moving rail 418, the driven shaft 428 is threadedly connected to the other one of the fixed rail 416 and the moving rail 418, and the driven shaft 428 is connected with a driven gear 430 which is in meshing transmission with the driving gear 426.

[0071] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 , since the first floor to be laid 402 and the second floor to be laid 404 are the passenger compartment floor of the rail vehicle, the adjustment amount of the passenger compartment floor is relatively small when the passenger compartment floor is actually laid, and thus in the embodiment of the present application, the driving mechanism 422 is mainly in the form of manual driving, and the distance between the first floor to be laid 402 and the second floor to be laid 404 can be timely adjusted by manual adjustment.

[0072] Please continue to refer to Figure 3 , the axis of the driving shaft 424 is perpendicular to the moving direction of the moving rail 418, that is, the driving shaft 424 can be vertically arranged and connected with the fixed rail 416, and the driving shaft 424 is connected with the driving gear 426. In order to realize the installation of the driving shaft 424, a fixing frame 440 can be arranged on the fixed rail 416, and the driving shaft 424 is installed on the fixing frame 440.

[0073] The axis of the driven shaft 428 is parallel to the moving direction of the moving rail 418, that is, the driven shaft 428 can be horizontally arranged and threadedly connected with the moving rail 418, and the driven shaft 428 is also arranged perpendicularly to the driving shaft 424, and the driven shaft 428 is connected with the driven gear 430. It can be understood that, since the axis of the driving shaft 424 is perpendicular to the axis of the driven shaft 428, the driving gear 426 and the driven gear 430 are umbrella gears in meshing transmission.

[0074] By such an arrangement, when the driving shaft 424 rotates, the driving shaft 424 synchronously drives the driving gear 426 to rotate. Since the driving shaft 424 is connected with the fixed rail 416, the driving shaft 424 remains stationary, and with the rotation of the driving gear 426, the driven gear 430 is in meshing transmission with the driving gear 426. Since the driven gear 430 is fixedly connected with the driven shaft 428, the driven gear 430 drives the driven shaft 428 to rotate relative to the moving rail 418. Since the driven shaft 428 is threadedly connected with the moving rail 418, the moving rail 418 will produce relative displacement with the fixed rail 416 with the rotation of the driven shaft 428, thereby driving the first floor to be laid 402 and the second floor to be laid 404 to produce relative movement.

[0075] Of course, in other embodiments, the driving shaft 424 can be connected with the movable rail 418, and the driven shaft 428 can be connected with the fixed rail 416. In this way, when the driven shaft 428 rotates relative to the fixed rail 416, the movable rail 418 can be driven to move relative to the fixed rail 416, thereby driving the first floor panel 402 and the second floor panel 404 to move relative to each other.

[0076] It can be understood that, in the embodiment of the present application, the driving of the driving shaft 424 and the driven shaft 428 is realized through the engagement of the driving tooth 426 and the driven tooth 430, so that the driving between the driving shaft 424 and the driven shaft 428 is more accurate, efficient, reliable, and long in service life, and the moving precision of the first floor panel 402 and the second floor panel 404 during the relative movement is improved.

[0077] According to an embodiment of the present application, the end of the driving shaft 424 is further provided with a knob 432 for rotating the driving shaft 424.

[0078] Referring to Figure 3 In the embodiment of the present application, in order to facilitate the rotation of the driving shaft 424, an inner hexagonal hole 434 can be formed at the end of the driving shaft 424, and the knob 432 for driving the rotation of the driving shaft 424 is installed in the inner hexagonal hole 434. In actual operation, the rotation of the knob 432 can drive the rotation of the driving shaft 424.

[0079] Referring to Figure 3 In the embodiment of the present application, the adjusting assembly 410 further comprises a protective shell 436, which can be directly installed on the fixed rail 416. In order to reduce the friction between the driving shaft 424, the driven shaft 428 and the protective shell 436, bearings 438 corresponding to the driving shaft 424 and the driven shaft 428 are installed on the protective shell 436, and the driving shaft 424 and the driven shaft 428 are respectively arranged in the bearings 438. The bearing 438 corresponding to the driving shaft 424 can be directly installed on the fixed frame 440.

[0080] According to an embodiment of the present application, the driving mechanism 422 comprises a linear driving member, which is fixedly connected to one of the fixed rail 416 and the movable rail 418, and the output end of the linear driving member is adapted to be connected to the other one of the fixed rail 416 and the movable rail 418 through a transmission member.

[0081] In other embodiments, the driving mechanism 422 can further comprise a linear driving member, such as a linear motor. The linear motor can be connected with the fixed rail 416, and the output shaft of the linear motor can be connected with the movable rail 418. When the linear motor operates, the output end can drive the movable rail 418 to move relative to the fixed rail 416.

[0082] The second aspect of the present application provides a floor laying method based on the floor laying device, comprising:

[0083] Step 100, connecting the first end of the movable rod 400 to the seat fixing hole 406 of one of the first floor to be laid 402 and the second floor to be laid 404;

[0084] Step 200, connecting the first end of the adjusting assembly 410 to the seat fixing hole 406 of the other of the first floor to be laid 402 and the second floor to be laid 404;

[0085] Step 300, adjusting the adjusting assembly 410 to adjust the relative distance between the first floor to be laid 402 and the second floor to be laid 404.

[0086] According to the floor laying method provided by the second aspect of the present application, the adjustment of the first floor to be laid 402 and the second floor to be laid 404 is facilitated, and the adjustment of the first floor to be laid 402 and the second floor to be laid 404 can still be realized when the connecting line of the seat fixing hole 406 on the first floor to be laid 402 and the seat fixing hole 406 on the second floor to be laid 404 is not parallel to the pulling direction of the adjusting assembly 410.

[0087] Referring to Figure 11 In step 100 provided by the embodiment of the present application, a nut seat 413 can be installed on the seat fixing hole 406 on the first floor to be laid 402 and the second floor to be laid 404 respectively, and then a movable rod 400 can be installed on each nut seat 413, and after installation, the pull rod 408 is hingedly connected to the movable rod 400;

[0088] In step 100, two different cases are involved:

[0089] Case one:
