[0043] 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

[0044] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0045] Secondly, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] Then, it should be noted that, in the description of the present application, the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0047] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0048] As shown in the background technology, in the prior art, during the process of replacing the wheel, since the non-toothed side wheel is first installed on the first end of the axle, the second end of the axle can only be lifted by a lifting belt or a wire rope, and then the axle with the non-toothed side wheel is placed vertically on the assembly table, and then the drive device of the axle is lifted by the wire rope and mounted on the axle, and the axle and the non-toothed side wheel with the assembled drive device are continuously placed to a nearly horizontal state by the wire rope, and finally the toothed side wheel is mounted on the second end of the axle.

[0049] However, the above assembly method is complicated and the assembly efficiency is low.

[0050] Moreover, since there is a gap between the drive device and the axle, when the axle and the non-toothed side wheel with the assembled drive device are placed in a nearly horizontal state using a wire rope, the drive device and the axle are prone to collision, which may cause damage to the axle.

[0051] Based on this, the present application provides a locomotive wheel assembly device, wherein the locomotive wheel includes an axle and a drive device. The locomotive wheel assembly device is provided by providing a support assembly, a hoisting assembly and a hoisting vehicle, and the hoisting vehicle has a first hook. The hoisting assembly includes a hoisting assembly body and a first connecting member and a second connecting member provided on the hoisting assembly body, wherein the first connecting member is slidably connected to the hoisting assembly body, the first connecting member is hooked to the first hook, and the second connecting member is connected to the first end of the axle; the support assembly is used to support the drive device, that is, the drive device is placed on the support assembly and fixed, so that the hoisting vehicle can hoist the axle and the drive device through the hoisting assembly. The first connecting member and the axle are both located on the same side of the second connecting member. When the first end of the axle is connected to the second connecting member, the center of gravity of the hoisting assembly connected to the axle moves in the direction toward the axle, thereby causing the axle and the hoisting assembly to tilt as a whole. The first connecting member slides relative to the lifting assembly body to allow the lifting assembly and the axle to rotate as a whole relative to the first hook, thereby adjusting the relative position of the axle and the drive device so that the second end of the axle faces the drive device, so that the second end of the axle can be inserted into the drive device, thereby completing the assembly of the axle and the drive device. The assembly method is convenient and the assembly efficiency is improved.

[0052] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0053] Reference Figure 1 As shown, the locomotive wheelset assembly device provided in the present application comprises an axle 10 and a drive device 20 , and the locomotive wheelset assembly device comprises a support assembly 100 , a hoisting assembly 200 and a hoisting vehicle 300 , and the hoisting vehicle 300 has a first hook 310 .

[0054] The hanging assembly 200 includes a hanging assembly body 210 and a first connecting member 220 and a second connecting member 230 disposed on the hanging assembly body 210 . The first connecting member 220 is slidably connected to the hanging assembly body 210 , and the first connecting member 220 is used to hang with the first hook 310 .

[0055] The second connecting member 230 is used to connect to the first end 11 of the axle 10 , and the first connecting member 220 and the axle 10 are both located on the same side of the second connecting member 230 .

[0056] The support assembly 100 is used to support the driving device 20 . The first connecting member 220 slides relative to the hoisting assembly body 210 to adjust the relative position of the axle 10 and the driving device 20 so that the second end 12 of the axle 10 is inserted into the driving device 20 .

[0057] Exemplarily, the crane 300 may be a bridge crane horizontally mounted above a workshop, such as an overhead crane, or may be a tire crane with a cab or an operator's room. The present application does not impose too many restrictions on the type of the crane 300.

[0058] The lifting vehicle 300 has a first hook 310, and the first connecting member 220 is connected to the first hook 310, so that the lifting component 200 is connected to the lifting vehicle 300 through the first connecting member 220 and the first hook 310. The lifting vehicle 300 can lift the lifting component 200, that is, the lifting vehicle 300 can drive the lifting component 200 to move in the vertical direction or the horizontal direction to drive the lifting component 200 to move to connect with the axle 10.

[0059] The second connecting member 230 is connected to the axle 10, and the second connecting member 230 provides a connection position for the axle 10. The axle 10 is connected to the lifting assembly body 210 through the second connecting member 230, so that the lifting vehicle 300 can lift the axle 10 through the lifting assembly 200 to complete the lifting of the axle 10 and the driving device 20.

[0060] The support assembly 100 is used to support the drive device 20. For example, the drive device 20 can be hoisted onto the support assembly 100 by a steel wire rope so that the drive device 20 is placed on the support assembly 100 and fixed. Since the connection position between the drive device 20 and the axle 10 is located at the center of the drive device 20, the center of the drive device 20 faces the axle 10 and the hoisting assembly 200, that is, faces the Figure 1 The arrow in the middle indicates the -X direction.

[0061] It can be understood that the hoisting assembly 200 is connected to the hoisting vehicle 300 through the first connecting member 220. When the center of gravity of the hoisting assembly 200 and the line connecting the first connecting member 220 are perpendicular to the ground, the hoisting assembly 200 is in a balanced state. When the center of gravity of the hoisting assembly 200 changes, the hoisting assembly 200 may tilt relative to the hoisting vehicle 300.

[0062] Specifically, when the first end 11 of the axle 10 is connected to the second connecting member 230, the axle 10 is located at the second connecting member 230. Figure 1The middle arrow indicates the +X direction, so the center of gravity of the hoisting assembly 200 after being connected to the axle 10 moves in the direction toward the axle 10 , so that the hoisting assembly 200 and the axle 10 are tilted as a whole, that is, the axle 10 deviates from the center of the driving device 20 . Since the first connecting member 220 and the axle 10 are both located on the same side of the second connecting member 230, that is, the first connecting member 220 and the axle 10 are both located in the +X direction of the second connecting member 230, and since the first connecting member 220 is slidably connected to the lifting component body 210, the first connecting member 220 can slide relative to the lifting component body 210 along the +X direction, so that the lifting component 200 and the axle 10 are rotated as a whole relative to the first hook 310, thereby adjusting the relative position of the axle 10 and the drive device 20 until the second end 12 of the axle 10 is opposite to the center of the drive device 20, and then the lifting vehicle 300 drives the lifting component 200 and the axle 10 to move along the +X direction, so that the axle 10 is inserted into the drive device 20, thereby completing the assembly of the axle 10 and the drive device 20.

[0063] The locomotive wheel set includes an axle 10 and a drive device 20. It should be noted that the locomotive wheel set may also include a non-toothed side wheel 30 and a toothed side wheel. When assembling the locomotive wheel set, the non-toothed side wheel 30 is first installed on the first end 11 of the axle 10, and then the axle 10 and the drive device 20 are assembled through the hoisting assembly 200 and the hoisting vehicle 300. At this time, the non-toothed side wheel 30, the axle 10 and the drive device 20 are all located on the support assembly 100, so that the hoisting assembly 200 can be separated from the axle 10, and finally the toothed side wheel is sleeved on the second end 12 of the axle 10, thereby realizing the assembly of the locomotive wheel set, and the assembly method is convenient and the assembly efficiency is improved.

[0064] Moreover, after the axle 10 and the drive device 20 are assembled, the gear side wheels can be directly assembled without lifting the axle 10 and the drive device 20, thereby reducing the collision between the axle 10 and the drive device 20, reducing the possibility of damaging the axle 10, and saving costs.

[0065] In some embodiments, reference Figure 2 As shown, the hanging assembly body 210 includes a first hanging component 211 and a second hanging component 212 arranged on one side of the first hanging component 211, and the first hanging component 211 and the second hanging component 212 are perpendicular to each other.

[0066] The first connecting member 220 is slidably connected to the first hanging member 211 , and the second connecting member 230 is disposed at an end of the second hanging member 212 away from the first hanging member 211 .

[0067] Reference Figure 1 and Figure 2As shown, the sling assembly body 210 is provided with a first sling 211 and a second sling 212, and the second sling 212 is located on one side of the first sling 211, that is, the sling assembly body 210 is in an "L" shape. The first connecting member 220 is slidably connected to the first sling 211, and the second connecting member 230 is provided at the end of the second sling 212 away from the first sling 211. Since the second connecting member 230 is connected to the axle 10, the first connecting member 220 and the axle 10 are both located at the second connecting member 230. Figure 1 The +X direction indicated by the middle arrow, that is, the center of gravity of the lifting assembly 200 connected with the axle 10 moves in the direction toward the axle 10, so that the first connecting member 220 slides relative to the first lifting member 211 in the +X direction to adjust the relative position of the axle 10 and the driving device 20.

[0068] It should be noted that, when the axle 10 is inserted into the drive assembly, the first hanging member 211 is located above the axle 10, the non-toothed side wheel 30 and the drive assembly, so the second connecting member 230 should be arranged at the end of the second hanging member 212 away from the first hanging member 211, that is, there is a certain distance between the second hanging member 230 and the first hanging member 211, and the distance should be greater than the radius of the non-toothed side wheel 30 and the drive device 20.

[0069] In some embodiments, reference Figure 2 and Figure 3 As shown, the locomotive wheelset assembly device further includes a limiting member 240 , the first connecting member 220 is provided with a plug-in portion 221 and a limiting hole connected to the plug-in portion 221 , and the first hanging member 211 is slidably connected to the first connecting member 220 via the plug-in portion 221 .

[0070] The limiting member 240 abuts against the first hanging member 211 through the limiting hole.

[0071] The first connecting member 220 is provided with an inserting portion 221. By way of example, the inserting portion 221 may be a slide groove or a through hole, and the present application does not impose too many restrictions on this.

[0072] The limiting member 240 is in contact with the first hanging member 211 through the limiting hole. For example, the limiting hole can be a threaded hole, and the limiting member 240 can be a bolt that matches the threaded hole. By screwing the bolt, the bolt can be in contact with or out of contact with the first hanging member 211. When the bolt is out of contact with the first hanging member 211, the first connecting member 220 can slide relative to the first hanging member 211. When the bolt is in contact with the first hanging member 211, the first connecting member 220 is fixed on the first hanging member 211.

[0073] In some embodiments, reference Figure 1 and Figure 2As shown, a connecting portion 222 is provided on the first connecting member 220 , and the connecting portion 222 is used to be hooked with the first hook 310 .

[0074] The connecting portion 222 is used to be connected with the first hook 310. Exemplarily, the connecting portion 222 can be a through hole or a bent hook facing the first hook 310. The present application does not impose too many restrictions on the type of the connecting portion 222.

[0075] In some embodiments, reference Figure 1 and Figure 3 As shown, the second connecting member 230 has a plug hole 231 , and the plug hole 231 is used for the first end 11 of the axle 10 to be plugged into the second connecting member 230 .

[0076] By setting the plug hole 231 on the second connecting member 230, a plug-in position is provided for the axle 10. The hoisting assembly 200 is driven to move by the hoisting vehicle 300 to achieve the plugging of the axle 10 with the plug hole 231. The operation is simple and the work efficiency is improved.

[0077] In some embodiments, reference Figure 1 and Figure 3 As shown, a protective sleeve 232 is embedded in the plug hole 231 , and the protective sleeve 232 is used to contact the axle 10 .

[0078] It should be noted that due to the large weight of the axle 10, in order to ensure that the axle 10 will not be deformed when the lifting assembly 200 lifts it, the lifting assembly 200 can be made of steel with high hardness and strength. The second connecting member 230 on the lifting assembly 200 is also made of steel. Therefore, when the axle 10 is inserted into the plug hole 231, the axle 10 and the plug hole 231 may collide, thereby causing damage to the axle 10. Therefore, by embedding a protective cover 232 in the plug hole 231, the collision between the axle 10 and the plug hole 231 when the axle 10 is inserted into the plug hole 231 can be avoided, thereby reducing the wear of the axle 10 and improving the reliability of the lifting assembly 200.

[0079] In some embodiments, reference Figure 3 As shown, the protective sleeve 232 is a copper sleeve.

[0080] It can be understood that the hardness of copper is lower than that of steel, and embedding a copper sleeve in the plug hole 231 can reduce the wear of the axle 10.

[0081] In some embodiments, reference Figure 1 and Figure 4 As shown, the support assembly 100 includes a support plate 110 and two support columns 120 . The two support columns 120 are spaced apart on the support plate 110 , and the support columns 120 are used to support the driving device 20 .

[0082] Two support columns 120 are spaced apart on the support plate 110 , and the driving device 20 is placed between the two support columns 120 . The two support columns 120 together provide support for the driving device 20 .

[0083] Exemplarily, the drive device 20 may include a transmission plate, a connecting rod pin, a hollow shaft sleeve and a driven gear. When assembling the locomotive wheel assembly, the transmission plate can be placed on the support column 120 first. After the axle 10 is inserted on the transmission plate, the connecting rod pin, the hollow shaft sleeve and the driven gear sleeve are sequentially installed on the axle 10 to complete the assembly of the axle 10 and the drive device 20.

[0084] In some embodiments, reference Figure 1 and Figure 4 As shown, the top of the support column 120 has a support surface 121 , and the support surface 121 is in an arc shape that matches the side surface of the driving device 20 , and the support surface 121 is used to abut against the driving device 20 .

[0085] It can be understood that by setting a support surface 121 on the top of the support column 120, and the support surface 121 is in an arc shape that matches the side of the driving device 20, the contact area between the support column 120 and the driving device 20 is increased, thereby further improving the reliability of the support assembly 100.

[0086] In some embodiments, reference Figure 1 and Figure 2 As shown, the lifting vehicle 300 has a second hook 320, and the lifting assembly 200 also includes a third connecting member 250, which is connected to the lifting assembly body 210. The third connecting member 250 and the second connecting member 230 are both located on the same side of the first connecting member 220, and the third connecting member 250 is used to be hung with the second hook 320.

[0087] It can be understood that by connecting the third connecting member 250 with the second hook 320, the connection portion between the lifting assembly 200 and the lifting vehicle 300 is increased, thereby improving the stability of the lifting assembly 200 during the lifting process.

[0088] In a specific implementation, the first connecting member 220 and the axle 10 are both located at the second connecting member 230. Figure 1 In the +X direction, after the axle 10 is connected to the second connecting member 230, since the center of gravity of the lifting assembly 200 moves in the direction toward the axle 10, the first connecting member 220 needs to slide in the +X direction. Therefore, the third connecting member 250 should be located in the -X direction of the first connecting member 220, that is, the third connecting member 250 and the second connecting member 230 are both located on the same side of the first connecting member 220.

[0089] Those skilled in the art can understand that the locomotive wheel assembly device provided in the present application includes an axle 10 and a drive device 20. The locomotive wheel assembly device is provided by providing a support assembly 100, a hoisting assembly 200 and a hoisting vehicle 300, and the hoisting vehicle 300 has a first hook 310. The hoisting assembly 200 includes a hoisting assembly body 210 and a first connecting member 220 and a second connecting member 230 provided on the hoisting assembly body 210. The first connecting member 220 is slidably connected to the hoisting assembly body 210, the first connecting member 220 is hooked to the first hook 310, and the second connecting member 230 is connected to the first end 11 of the axle 10; the support assembly 100 is used to support the drive device 20, that is, the drive device 20 is placed on the support assembly 100 and fixed, so that the hoisting vehicle 300 can hoist the axle 10 and the drive device 20 through the hoisting assembly 200.

[0090] The first connecting member 220 and the axle 10 are both located on the same side of the second connecting member 230. When the first end 11 of the axle 10 is connected to the second connecting member 230, the center of gravity of the lifting assembly 200 connected to the axle 10 moves in the direction toward the axle 10, thereby causing the axle 10 and the lifting assembly 200 to tilt as a whole.

[0091] The first connecting member 220 slides relative to the lifting component body 210 to allow the lifting component 200 and the axle 10 to rotate as a whole relative to the first hook 310, thereby adjusting the relative position of the axle 10 and the drive device 20 so that the second end 12 of the axle 10 is opposite to the drive device 20, so that the second end 12 of the axle 10 can be inserted into the drive device 20, thereby completing the assembly of the axle 10 and the drive device 20. The assembly method is convenient, saves manpower, and improves assembly efficiency.
