Description

Technical Field

[0001] This application relates to the field of railway technology, and in particular to wheelset conveying devices. Background Technology

[0002] Wheelsets are the parts of railway locomotives and rolling stock that come into contact with the rails. They consist of two wheels securely mounted on the same axle. They are a crucial component of railway locomotives, ensuring stable operation and steering on the rails. Therefore, the inspection and maintenance of wheelsets are essential for ensuring the safe operation of railway locomotives and rolling stock. During wheelset maintenance, the wheelsets must be placed in designated maintenance equipment.

[0003] Currently, the common method is to push forward manually, but this method is time-consuming, labor-intensive, and prone to causing bumps and crushing injuries to people.

[0004] Therefore, there is an urgent need for wheelset conveying devices to address, to some extent, the technical problems existing in the current technology. Summary of the Invention

[0005] The purpose of this application is to provide a wheelset conveying device that does not require manual movement of the wheelsets and can ensure that the wheelsets can pass normally through equipment such as wheelset cleaning machines, rust removal machines, and wheelset flaw detectors.

[0006] This application provides a wheelset conveying device, including

[0007] A support frame, the support frame including vertical rails spaced apart along a first direction for supporting wheelsets;

[0008] The driven push assembly includes a moving part and a pushing part; the moving part is disposed on the vertical rail and extends along the extension direction of the vertical rail; the pushing part is rotatably disposed on the moving part at intervals along the extension direction of the moving part, and at least a portion of the pushing part can protrude from the moving part toward the wheelset;

[0009] A drive assembly, the output end of which is connected to the moving part, is capable of driving the moving part and the pushing part to move along the extension direction of the vertical rail;

[0010] When the pushing part moves along the second direction and passes the wheelset, the pushing part can rotate clockwise and the portion of the pushing part protruding from the moving part is concealed within the moving part; after the pushing part moves along the second direction and passes the wheelset, the pushing part can rotate counterclockwise and at least a portion of the pushing part is exposed within the moving part; when the pushing part moves along a third direction, the pushing part exposed within the moving part can limit the wheelset and drive the wheelset to move simultaneously along the third direction.

[0016] In the above technical solution, a sponge rubber layer is further provided in the rim groove. The sponge rubber layer is used to increase the friction between the rim of the wheelset and the rim groove to prevent the rim of the wheelset from moving freely due to inertia.

[0020] In the above technical solution, the side of the vertical rail facing the driven push plate is provided with a guide rail extending along the extension direction of the vertical rail; the side of the driven push plate facing is provided with a slider that can move on the guide rail.

[0021] In the above technical solution, a lead screw is further provided below the driven push plate away from the wheelset, and the driven push plate is connected to the lead screw through a guide block;

[0022] The output end of the drive component is connected to the lead screw.

Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0052] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0053] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0054] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0059] Wheelsets (7) are a crucial component of railway locomotives, ensuring their stable operation and steering on the rails. Therefore, the inspection and maintenance of wheelsets (7) are essential for the safe operation of railway locomotives and rolling stock. This application provides a wheelset (7) conveying device that can transport wheelsets (7) to maintenance equipment without manual pushing, thus mitigating to some extent the risks of personnel bumping and crushing injuries caused by manual pushing in existing technologies. The following is a detailed explanation... Figures 1-14 This application provides a detailed description of a wheelset 7 conveying device.

[0060] The wheel-to-wheel conveyor includes a support frame 3, a moving propulsion assembly, and a drive assembly 1; the specific structure of the support frame 3, the moving propulsion assembly, and the drive assembly 1, as well as their interconnections, are described in detail below with reference to the accompanying drawings.

[0061] Specifically, in combination Figure 4 and Figure 5 As shown, the support frame 3 includes a fixed beam 304, a base mounting plate 305, and vertical rails 301; two vertical rails 301 are provided, and the two vertical rails 301 are arranged at intervals along the first direction 5 to combine Figure 1Taking the direction shown as an example, the two vertical rails 301 are arranged at intervals along the width direction of the wheelset 7; the two wheels 704 of the wheelset 7 are positioned precisely on the two vertical rails 301, so that the vertical rails 301 can support the wheels 704. The two ends of the fixing beam 304 are respectively connected to the two vertical rails 301, thus connecting the two vertical rails 301. Optionally, multiple fixing beams 304 are provided, and the multiple fixing beams 304 are arranged at equal intervals along the length of the vertical rails 301, thereby improving the overall stability of the support frame 3 in the second direction 6 and preventing the two vertical rails 301 in the support frame 3 from running across the ground in the second direction 6. The foot mounting plate 305 is located on the side of the vertical rail 301 facing the ground, and can be installed on the ground using connectors to fix the vertical rail 301 to the ground. Optionally, the foot mounting plate 305 is integrally formed with the side of the vertical rail 301 facing the ground. Optionally, the connector is a connecting bolt 206, that is, the foot mounting plate 305 is installed on the ground by means of the connecting bolt 206.

[0062] Specifically, the driven push assembly 2 includes a moving part and a pushing part; wherein the moving part is disposed on the opposite sidewalls of the two vertical rails 301 and extends along the extension direction of the vertical rails 301; wherein the pushing part is rotatably disposed on the moving part at intervals along the extension direction of the moving part, and at least a portion of the pushing part can protrude out of the moving part toward the wheelset 7.

[0063] Specifically, combined Figures 1-3 As shown, the driven push assembly 2 includes a driven push plate 203 that can function as a movable part and a push block 204 that can function as a push part; wherein, the driven push plate 203 has a mounting groove 211 spaced apart on the side near the vertical rail 301, and this mounting groove 211 provides a receiving space for mounting the push block 204. Furthermore, the push block 204 is rotatably mounted in the mounting groove 211 via a push block shaft 207; Figure 2 As can be seen, the tip of the pusher 204 is exposed in the mounting groove 211.

[0064] Specifically, combined Figure 3As shown, the push block 204 has a near-right-angled triangular structure, and it gradually widens along the direction from the wheelset 7 to the ground. This can be understood as the longer right-angled side of the near-right-angled triangular push block 204 being parallel to the extension direction of the driven push plate 203, and the shorter right-angled side being perpendicular to the extension direction of the driven push plate 203 and protruding from the driven push plate 203 towards the wheelset 7. Furthermore, the shorter right-angled side is closer to the maintenance equipment. In other words, the weight of the push block 204 gradually increases from the wheelset 7 to the ground. Therefore, when not in use, because the weight at the bottom of the push block 204 is greater than the weight at the top, the tip of the push block 204 near the wheelset 7 protrudes from the driven push plate 203. Specifically, the push block shaft 207 passes through the right-angled end of the push block 204 and is fixed to the driven push plate 203 at the position corresponding to the mounting groove 211.

[0065] It is worth noting that: the hidden driven push plate 203, when from Figure 1 When viewing the wheelset 7 conveyor from the left side (i.e., from the maintenance equipment towards the wheelset 7 conveyor), what is seen is the short right-angled side of the push block 204 (see reference). Figure 9 ); when from Figure 1 When viewing the wheelset 7 conveyor from the right side (i.e., looking at the wheelset 7 conveyor from away from the maintenance equipment), what you see is the slanted side of the push block 204.

[0066] Specifically, the output end of the drive assembly 1 is connected to the moving part, that is, the output end of the drive assembly 1 is connected to the driven push plate 203, and can drive the driven push plate 203 to move along the second direction 6 or the third direction 8 (in Figure 1 As shown in the diagram, the second direction 6 refers to the extension direction of the vertical rail 301 to the right, and the third direction 8 refers to the extension direction of the vertical rail 301 to the left. Since the push block 204 is connected to the driven push plate 203 through the push block shaft 207, the push block 204 will also move along the second direction 6 or the third direction 8 when the driven push plate 203 moves along the second direction 6 or the third direction 8.

[0067] In actual use, when the driven push assembly 2 completes the first batch of wheel sets 7 conveying (after completing the first batch, the driven push assembly 2 approaches the maintenance equipment), it is necessary to convey the second batch of wheel sets 7 (in conjunction with...). Figure 12 As shown, when the second batch of wheelsets 7 are already on the vertical rail 301, it is necessary to start the drive assembly 1 to rotate forward and drive the driven assembly 2 (from... Figure 12 The relative positions of the driven push plate 203 and the drive component 1 (the drive component 1 is located at the leftmost end of the driven push plate 203) show that the driven push component 2 has just completed the first batch of pushes of the secondary wheel pair 7 and moved to the initial position (combined with...). Figure 14As shown, in the initial position, the drive assembly 1 should be at the far left of the driven push plate 203, that is, all push blocks 204 should be pushed in the direction away from the maintenance equipment to prepare for conveying the second batch of wheelsets 7.

[0068] Combination Figure 13 As shown, when the driven push plate 203 moves along the second direction 6 and passes the wheel set 7, the push block 204 can rotate clockwise and the part of the push block 204 protruding from the driven push plate 203 is hidden in the mounting groove 211 of the driven push plate 203. Furthermore, when the driven push plate 203 moves along the second direction 6, i.e., moves away from the maintenance equipment and passes the wheel set 7, the inclined edge of the push block 204 will first contact the wheel set 7. During the continued movement, the push block 204 moves to the right, and the wheel set 7 moves to the left relative to the push block 204. At this time, the wheel set 7 will apply downward pressure to the push block 204, which will cause the push block 204 to rotate clockwise around the push block axis 207 and be hidden in the mounting groove 211. That is, during the process of the driven push assembly 2 moving to the right, the push block 204 and the wheel set 7 will not interfere with each other, and the driven push assembly 2 can smoothly reach the initial position. It is worth noting that during this stage, when the push plate passes the wheel set 7, it will be pressed down by the wheel set 7 and hidden in the mounting groove 211. After the push plate passes the wheel set 7, the push plate will rotate counterclockwise due to the greater weight at the bottom and the smaller weight at the top, causing the tip of the push block 204 to be exposed on the driven push plate 203.

[0069] Combination Figure 14 As shown, based on the relative positional relationship between the driven push plate 203 and the drive assembly 1 (the drive assembly 1 is located at the leftmost end of the driven push plate 203), the driven push plate 203 and the push block 204 have already moved to their initial positions. Then, the drive assembly 1 is activated to rotate in the reverse direction, driving the driven push plate 203 to move along the third direction 8. During this movement, the push block 204 protruding from the driven push plate 203 will engage with the wheel 704 of the wheelset 7, and drive the wheel 704 to move along the third direction 8 in coordination, ultimately moving the wheelset 7 into the maintenance equipment. It is worth noting that each push plate engages with one wheelset, so during another push, multiple push plates will push multiple wheelsets 7 at once.

[0070] In summary, this application utilizes the drive component 1 to drive the driven push component 2 to move along the second direction 6 or the third direction 8, thereby enabling the wheelset 7 to be smoothly pushed into the maintenance equipment without the need for manual pushing, which to some extent solves the problem of personnel bumps and crush injuries caused by manual pushing in the prior art.

[0071] In this embodiment, combined with Figure 13 and Figure 14As shown, the hypotenuse of the push block 204 is not a straight line. The hypotenuse of the push block 204 includes a first straight line segment and a second straight line segment connected sequentially along the direction from the wheel set 7 to the ground. The first straight line segment and the second straight line segment are at 150°, which is equivalent to forming a buffer transition slope between the first straight line segment and the second straight line segment. In this way, when the push block 204 moves along the second direction 6 and passes the wheel set 7, the impact force of the wheel set 7 on the push block 204 will be reduced.

[0072] In this embodiment, the inclined side of the push block 204 is provided in a different form than that described above. Specifically, the inclined side of the push block 204 has a certain curvature, making the inclined side of the push block 204 concave. In addition, its curvature is the same as that of the wheelset 7. In this way, when the push block 204 passes the wheel 704, the wheel 704 and the push block 204 are matched.

[0073] In this embodiment, combined with Figure 11 As shown, the wheelset 7 includes wheels 704 and axle 703, with the two wheels 704 connected by the axle 703. Each wheel 704 includes a rim 701 and a tread 702. (Combined) Figure 9 As shown, the end face 212 of the vertical rail 301 facing the wheelset 7 has a rim groove 302 for the rim 701 of the wheelset 7 to roll; the end face 212 of the vertical rail 301 facing the wheelset 7 also has an abutment edge 306 extending toward the driven push plate 203, which is combined with 9 and Figure 9 As shown, the abutment edge 306 is parallel to the second direction 6. The sum of the width of the abutment edge and the width of the driven push plate 203 toward the end face 212 of the wheel set 7 is equal to the width of the tread surface 702 of the wheel set 7.

[0074] In summary, in this embodiment, the width of the driven push plate 203 and the abutment edge 306 is exactly equal to the width of the tread surface 702 of the wheel 704. This means the driven push plate 203 does not occupy any extra space; it essentially divides the existing vertical rail 301 into two parts along its width, one part supporting the wheel 704 and the other part transporting the wheel 704. As a result, the driven push assembly 2 does not occupy any extra space in the vertical rail 301, ensuring that when the wheelset 7 is transported using the driven push assembly 2, it will not interfere with components within the maintenance equipment. This solves the technical problem of existing equipment with push shafts being unable to pass through wheelset cleaning machines, rust removers, and flaw detectors within the maintenance equipment during the movement of the wheelset 7.

[0075] In this embodiment, combined with Figure 11As shown, a sponge rubber layer 4 is provided inside the rim groove 302. Specifically, the sponge rubber layer 4 is provided on the side wall of the rim groove 302. In actual use, the drive assembly 1 first needs to drive the driven push assembly 2 to its original position; then the drive assembly 1 drives the driven push plate 203 to move toward the third direction 8. During the process of driving the driven push plate 203 to move toward the third direction 8, the push block 204 will abut against the wheelset 7 at an instant under the driving force of the drive assembly 1. Since the force of the drive assembly 1 is relatively large, at the instant the push block 204 abuts against the wheelset 7, the wheelset 7 may move freely on the vertical rail 301 under the action of the abutment force or inertial force. In order to overcome the above problem, this embodiment provides a sponge rubber layer 4 inside the rim groove 302. The sponge rubber layer 4 increases the friction between the rim 701 of the wheelset 7 and the rim groove 302 to prevent the rim 701 of the wheelset 7 from moving freely due to inertia.

[0076] In this embodiment, the distance between adjacent push blocks 204 is greater than or equal to the distance between adjacent wheel pairs 7, ensuring that no interference occurs between adjacent wheels 704 when the push block 204 pushes the wheel 704.

[0077] In this embodiment, combined with Figure 3 and Figure 8 As shown, a rack 202 is provided on the driven push plate 203 away from the edge of the wheelset 7, that is, a rack 202 is provided below the driven push plate 203, and the rack 202 is fixed to the bottom of the driven push plate 203 by a rack positioning pin 208.

[0078] A gear 201 that meshes with a rack 202 is fitted on the output shaft 109 of the drive assembly 1. In actual use, the drive assembly 1 drives the gear 201 to rotate clockwise to drive the driven push plate 203 to move along the second direction 6; or the drive assembly 1 drives the gear 201 to rotate counterclockwise to drive the driven push plate 203 to move along the third direction 8.

[0079] Furthermore, a guide rail 303 extending along the extension direction of the vertical rail 301 is provided on the side of the vertical rail 301 facing the driven push plate 203; a slider 205 is provided on the side of the driven push plate 203 facing the vertical rail 303 and is movable on the guide rail 303. That is, when the driving assembly 1 drives the driven push plate to move along the second or third direction 8, the driven push plate 203 can slide on the guide rail 303 via the slider 205. In other words, the sliding action between the slider 205 and the guide rail 303 provides an auxiliary and guiding function for the driven push assembly 2.

[0080] In this embodiment, the movement of the driven push component 2 is provided in a different manner than the meshing of the gear 201 and rack 202 described above. Specifically, a lead screw is provided on the driven push plate 203 away from the bottom of the wheelset 7, and the driven push plate 203 is connected to the lead screw through a guide block. In actual use, the output end of the drive component 1 is connected to the lead screw, and the drive component 1 drives the lead screw to rotate clockwise to drive the driven push plate 203 to move along the second direction 6; or the drive component 1 drives the lead screw to rotate counterclockwise to drive the driven push plate 203 to move along the third direction 8.

[0081] In this embodiment, combined with Figure 6 and Figure 7 As shown, the drive assembly 1 includes a servo motor 112, a reducer 111, and a mounting bracket 113. The servo motor 112 is mounted on the side of the support frame 3 facing the ground via the mounting bracket (the mounting bracket is fixed to the support frame 3 by fixing bolts 114). The reducer 111 is connected to the servo motor 112 via an external coupling.
