[0029] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The present application provides a translation device and station equipment.

[0031] like Figure 1 and Figure 2 As shown, the translation device provided by the present application includes a driving unit 10 and a plurality of translation units 20. In the figure, two translation units 20 are provided, but of course, the number is not limited to two. The driving unit 10 is used to drive the translation unit 20 to translate in the lateral direction. The translation unit 20 is used to support the concave chassis of the piggyback transport vehicle.

[0032] The station equipment provided by the present application includes a translation device, an end chassis lifting device and a concave chassis lifting device.

[0033] The driving unit 10 can drive the translation unit 20 to move the concave chassis of the piggyback transport vehicle from above the track to the side of the track. The specific process is: the end chassis lifting device lifts the end chassis of the piggyback transport vehicle, and the concave chassis lifting device lifts the concave chassis of the piggyback transport vehicle. The lifting heights are different, so that the end chassis and the concave chassis can be unhooked. Then, the driving unit 10 drives the translation unit 20 to translate below the concave chassis, and then the concave chassis lifting device makes the concave chassis fall onto the translation unit 20. Then the driving unit 10 drives the translation unit 20 and the concave chassis to translate to the side of the track together. Of course, the driving unit 10 can also drive the translation unit 20 to move the concave chassis from the side of the track to above the track.

[0034] like Figure 1 As shown, each translation part 20 is arranged in sequence and spaced apart in the longitudinal direction. To ensure that the translation part 20 can reliably support the concave bottom frame, it is preferred that each translation part 20 is symmetrically distributed about the transverse central axis of the concave bottom frame, for example, Figure 1The two translation parts 20 are symmetrically distributed about the transverse center axis (line C in the figure) of the concave chassis.

[0035] like Figure 3 or Figure 4 As shown, the driving part 10 includes a connecting shaft 101 and a plurality of gears 102. In the figure, two gears 102 are provided, but the number is not limited to two. Each gear 102 of the driving part 10 is connected to the connecting shaft 101 and is arranged in sequence and spaced apart in the longitudinal direction.

[0036] like Figure 5 As shown, the translation part 20 includes a rack 201 extending in the transverse direction. The rack 201 of each translation part 20 is meshed with different gears 102 of the driving part 10 respectively.

[0037] In the above-mentioned translation device, since the rack 201 of each translation part 20 is respectively meshed with different gears 102 of the driving part 10, and the different gears 102 of the driving part 10 are all connected to the same connecting shaft 101, when the connecting shaft 101 of the driving part 10 rotates under the drive of the power element 104, the different gears 102 of the driving part 10 will rotate synchronously, thereby driving the various translation parts 20 to move synchronously. When the concave chassis is moved, the concave chassis is supported on the various translation parts 20 of the translation device at the same time. If the moving speeds of the various translation parts 20 are different, it may cause the concave chassis to separate from part of the translation parts 20, and then cause one side of the concave chassis to lose support and tilt or even fall, so that the concave chassis cannot move smoothly. However, since the various translation parts 20 of the translation device of the present application can move synchronously, the concave chassis can move smoothly.

[0038] In a specific embodiment, Figure 1 As shown, a plurality of driving units 10 are provided, and each driving unit 10 is arranged in sequence and spaced apart in the transverse direction and is arranged in two groups, one group is arranged on one side of the vehicle track, and the other group is arranged on the other side of the vehicle track. Each group includes at least two driving units 10. Figure 1 In the figure, four driving parts 10 are provided in total, but of course, it is not limited to four, and two driving parts 10 form a group. The lateral distance between the two groups of driving parts 10 (indicated by M in the figure) is less than the length of the rack 201. The lateral distance between the two driving parts 10 that are farthest apart in the same group (indicated by L in the figure) is also less than the length of the rack 201. For example, if each group includes a first driving part 10, a second driving part 10 and a third driving part 10 that are arranged in sequence, then L refers to the lateral distance between the first driving part 10 and the third driving part 10. This design can ensure that the translation part 20 is engaged with the gear 102 of at least one driving part 10 during the translation process, thereby ensuring that the translation part 20 is driven by at least one driving part 10 during the translation process.

[0039] In a specific embodiment, Figure 4As shown, the connecting shaft 101 includes an intermediate shaft 1011 and two spline shafts 1012. Spline holes A are provided at both ends of the intermediate shaft 1011. The two spline shafts 1012 are respectively connected to the spline holes A at both ends. The gear 102 is connected to the spline shaft 1012. The gear 102 can be specifically connected to the spline shaft 1012 by a key, and of course it can also be other forms of connection, as long as it is guaranteed that the gear 102 can rotate synchronously with the spline shaft 1012. The diameter of the intermediate shaft 1011 is larger than the diameter of the spline shaft 1012. This split assembly type connecting shaft 101 is lower in cost and easier to ensure strength than the integrated connecting shaft 101.

[0040] In a specific embodiment, Figure 4 As shown, the intermediate shaft 1011 includes a tubular body 1011a and end plates 1011b fixed at both ends of the tubular body 1011a. The end plates 1011b can be fixed to the tubular body 1011a by welding, and other types of fixing forms are also possible. The spline hole A is set on the end plate 1011b. Compared with the integrated intermediate shaft 1011, this assembled intermediate shaft 1011 has a lower cost and forms a hollow structure, thereby reducing weight.

[0041] In a specific embodiment, Figure 5 and Figure 6 As shown, the translation part 20 includes a beam structure 202 extending in the transverse direction, a positioning structure 203 arranged above the beam structure 202, and a seat structure arranged below the beam structure 202. The seat structure includes two convex ridges 204 extending in the transverse direction, and the two convex ridges 204 are arranged in the longitudinal direction to form a groove 205. The rack 201 is fixed in the groove 205. The fixing method is not limited. If it is convenient to replace, it can be fixed with a threaded fastener. Figure 4 As shown, the middle portion of the gear 102 is higher than the two end portions. Fig. 9 As shown, the convex ridge 204 is supported on both end portions of the gear 102, the middle portion of the gear 102 extends into the groove portion 205 to mesh with the rack 201, and the middle portion of the gear 102 cooperates with the side wall of the groove portion 205 (i.e., there is only a small assembly gap between them). The cooperation between the middle portion of the gear 102 and the side wall of the groove portion 205 can guide the moving direction of the translation portion 20 on the one hand, and on the other hand, it can improve the meshing reliability of the gear 102 and the rack 201, so that the two are not easy to disengage, and on the other hand, it can prevent the vertical load from pressing the rack 201 and the gear 102 too tightly so that the gear 102 cannot rotate, thereby further improving the moving stability of the concave chassis.

[0042] In a specific embodiment, Figure 1 As shown, the translation device includes a first support portion 30. The first support portion 30 is used to support the translation portion 20 to improve the movement stability of the concave chassis. The first support portion 30 is located on the side of the vehicle track. Figure 1 In the embodiment, four first support parts 30 are provided, two of which are located on one side of the track and the other two are located on the other side of the track. Specifically, the first support parts 30 can be installed on the platform on the side of the track.

[0043] In a specific embodiment, Figure 7 and Figure 8 As shown, the first support portion 30 includes a support beam 301 extending in the transverse direction and a first support wheel 302 rotatably connected to the support beam 301. Specifically, the rotatable connection between the first support wheel 302 and the support beam 301 can be achieved by setting a connection hole and passing a wheel axle through the connection hole. Of course, the rotatable connection method is not limited to this. The structure of the first support wheel 302 is similar to that of the gear 102, and the middle part is also higher than the two end parts. The ridge part 204 is supported on the two end parts of the first support wheel 302. The middle part of the support wheel extends into the groove part 205 and cooperates with the side wall of the groove part 205 (that is, there is only a small assembly gap between them). The middle part of the first support wheel 302 cooperates with the side wall of the groove portion 205. On the one hand, it can guide the moving direction of the translation portion 20, and on the other hand, it can better improve the meshing reliability of the gear 102 and the rack 201, making it difficult for the two to disengage. On the other hand, it can prevent the vertical load from pressing the rack 201 and the gear 102 too tightly, making the gear 102 unable to rotate, thereby further improving the moving stability of the recessed chassis.

[0044] In a specific embodiment, Figure 7 and Figure 8 As shown, the first support part 30 includes two rows of rollers 303 rotatably connected to the support beam 301. Specifically, the rollers 303 and the support beam 301 can be rotatably connected by setting a connection hole and inserting a wheel axle in the connection hole. Of course, the rotatable connection method is not limited to this. The rollers 303 rotate around the vertical axis. A gap is formed between the two rows of rollers 303. Fig. 9 As shown, the beam structure 202 of the translation part 20 is an I-beam, and the two wing plates of the I-beam are respectively located above and below the two rows of rollers 303, and the web of the I-beam is inserted into the gap between the two rows of rollers 303 and cooperates with the two rows of rollers 303 (i.e., there is only a small assembly gap between them). The web of the I-beam cooperates with the two rows of rollers 303, which can guide the moving direction of the translation part 20 on the one hand, and the two rows of rollers 303 can stop the I-beam of the translation part 20 on the other hand, so as to prevent the translation part 20 from tipping over during the movement.

[0045] In a specific embodiment, Figure 8 As shown, the support beam 301 includes a side wall plate 301a and a bottom wall plate 301b, and the side wall plate 301a and the bottom wall plate 301b enclose an inner cavity. The gear 102 is located in the inner cavity of the support beam 301 (combined with Fig. 9The first support wheel 302 and the roller 303 are both located in the inner cavity of the support beam 301. Figure 8 As shown, a C-shaped frame 301c can be provided on the inner side of the upper end of each of the two side wall plates 301a of the support beam 301, and the two rows of rollers 303 can be installed in the two C-shaped frames 301c respectively. This design has high integration and saves space.

[0046] In a specific embodiment, the power element 104 of the driving unit 10 is fixed on the side wall plate 301a of the support beam 301 (combined with Figure 3 This design can further improve the integration. Specifically, the power element 104 of the driving unit 10 can be a motor or an electric machine. Specifically, a power element mounting seat 103 can be provided, the power element 104 is fixed on the power element mounting seat 103, and the power element mounting seat 103 is fixed on the side wall plate 301a of the support beam 301.

[0047] In a specific embodiment, Figure 1 As shown, the translation device includes a second support portion 40, which is used to support the translation portion 20. The second support portion 40 is located between the rails, and the second support portion 40 can ensure that the translation portion 20 can be reliably supported when it moves above the rails. Fig.10 As shown, the second support part 40 includes a bracket 401 and a second support wheel 402 rotatably connected to the bracket 401. Specifically, the second support wheel 402 and the bracket 401 can be rotatably connected by setting a connection hole and passing a wheel axle through the connection hole. Of course, the rotatable connection method is not limited to this. The structure of the second support wheel 402 is similar to that of the gear 102, and the middle part is higher than the two end parts. The ridge part 204 is supported on the two end parts of the second support wheel 402, and the middle part of the second support wheel 402 extends into the groove part 205 and cooperates with the side wall of the groove part 205 (that is, there is only a small assembly gap between them). The cooperation between the middle part of the second support wheel 402 and the side wall of the groove portion 205 can, on the one hand, guide the moving direction of the translation portion 20, and on the other hand, better improve the meshing reliability of the gear 102 and the rack 201, making it difficult for the two to disengage their teeth. On the other hand, it can prevent the vertical load from pressing the rack 201 and the gear 102 too tightly, making the gear 102 unable to rotate, thereby further improving the moving stability of the recessed chassis.

The description of the above embodiments is only used to help understand the method and core ideas of the present application.
