Description

Technical Field

[0001] This utility model relates to the field of disassembly and maintenance of wheelset axle boxes for high-speed trains, and in particular to a force-breaking and flipping device for disassembling axle boxes. Background Technology

[0002] After a certain period of operation, train wheelsets will develop defects such as abrasions, cracks, and fissures. Failure to repair these defects in a timely manner can lead to mechanical damage to the axles and rails, potentially causing safety accidents. Therefore, regular wheel maintenance is necessary. Currently, during wheel maintenance, disassembling the axle boxes typically relies on on-site lifting equipment (e.g., a gantry crane). Two ropes are attached to the end of the lifting hook, and these ropes are then tied to the manually rotated and aligned axle boxes. The wheelset axle boxes are then disassembled manually using force-breaking tools. This process is labor-intensive, and the simple lifting equipment cannot effectively rotate the axle boxes. Therefore, a device is needed that can automatically rotate and disassemble the axle boxes, reducing the intensity of manual labor. Utility Model Content

[0028] Optionally, the support mechanism includes:

[0038] The device of this invention fixes one side surface of the second gear to the second support frame, and rotatably fits the second gear onto the fixed shaft of the first support frame. By meshing the second gear with the first gear mounted on the first support frame, the second support frame can rotate relative to the first support frame. Since the gripper for holding the wheel box is set on the second support frame, the gripper can clamp the tilted wheel box by rotating the second support frame during the use of the device. By controlling the second support frame to rotate in the opposite direction to straighten the wheel box, the wheel box can be automatically flipped, reducing the labor intensity of workers and improving the efficiency of wheelset disassembly.

[0039] The drive motor of the device described in this utility model can drive the first gear to rotate forward and reverse, realizing the disassembly of the axle boxes symmetrically arranged on both sides of the wheelset; and the gripper can hold different types of axle boxes, saving the time of changing the gripper when disassembling different axle boxes, making the device of this utility model more versatile and improving the work efficiency of disassembling axle boxes.

[0040] The device of this utility model uses a parallel opening and closing pneumatic gripper with an air cut-off locking function to prevent the axle box from falling due to sudden air cut-off in the pneumatic pipeline. In addition, the device of this utility model is equipped with a protective mechanism.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] like Figure 1 and Figure 2 As shown, this utility model provides an axle box disassembly and force-breaking overturning device, which works in conjunction with a hoist to disassemble axle boxes 5 located on both sides of a wheelset. The axle box disassembly and force-breaking overturning device includes: a support mechanism, a rotating mechanism, and a force-breaking disassembly mechanism; the support mechanism is connected to the hoist; the rotating mechanism is connected to the support mechanism and can rotate relative to the support mechanism; the force-breaking disassembly mechanism is mounted on the rotating mechanism and is used to fix the axle box 5.

[0051] The support mechanism includes a support plate 12 and a first support frame 11. The first support frame 11 is a cuboid frame structure composed of first support rods, and has a fixed platform inside for placing a distribution box. The support plate 12 is fixed above the first support frame 11 and connected to it. The surface of the support plate 12 has a first connecting hole 121, which can be fitted onto the lifting part of the hoist. A plurality of fixing holes 122 are evenly distributed around the first connecting hole 121, which can be used to fix the hoist and the support plate 12 together, allowing the hoist to move the support mechanism.

[0052] In a preferred embodiment, to improve the load-bearing capacity of the support mechanism, the support plate 12 is made of carbon structural steel plate; the first support rod is made of aluminum alloy material.

[0053] In a preferred embodiment, the support mechanism further includes an auxiliary bracket 13, which is fixedly disposed on one side of the first support frame 11 to provide support for manual installation or maintenance of the device of this utility model.

[0054] Furthermore, a first fixing plate 111 is provided on one side of the first support frame 11 for fixing and connecting the rotating mechanism.

[0055] like Figure 3 As shown, the rotating mechanism includes: a second support frame, a drive motor 22, a fixed shaft 25, a first gear 23, and a second gear 24. The drive motor 22 is mounted on the first support frame 11, and its output end is provided with a rotating shaft; the rotating shaft passes through the first fixed plate 111, and is driven to rotate by the torque force provided by the drive motor 22. One end of the fixed shaft 25 is fixed to the first fixed plate 111, and it extends in the same direction as the rotating shaft.

[0056] The first gear 23 is fixed at its axis to a rotating shaft, which is connected to the drive motor 22. The drive motor 22 can drive the first gear 23 to rotate via the rotating shaft. The second gear 24 has a through hole at its axis, which is fitted onto a fixed shaft 25 and rotates in place around the fixed shaft 25. The second gear 24 meshes with the first gear 23, so that as the drive motor 22 sequentially drives the rotating shaft and the first gear 23 to rotate, the rotation of the first gear 23 drives the second gear 24 to rotate around the fixed shaft 25.

[0057] The second support frame includes at least two second fixing plates 21 that are perpendicularly connected to each other, and the two second fixing plates 21 are placed horizontally and vertically respectively, forming an L-shaped structure; wherein, the vertically placed second fixing plate 21 is fixed to one side surface of the second gear 24, so that the two sides of the second gear 24 are the first fixing plate 111 and the second fixing plate 21 respectively.

[0058] In a preferred embodiment, the thickness of the center position of the second gear 24 is greater than the thickness of the edge position of the second gear 24, so that there is a certain distance between the edge of the second gear 24 and the second fixing plate 21, preventing the surface of the second fixing plate 21 from contacting the first gear 23 and damaging the surface of the first gear 23 when the second fixing plate 21 rotates.

[0059] When the drive motor 22 is working, it drives the first gear 23 to rotate through the drive shaft, and then the first gear 23 drives the second gear 24 to rotate around the fixed shaft 25. Since one side surface of the second gear 24 is fixed on the second fixed plate 21 of the second support frame, the second fixed plate 21 rotates coaxially with the second gear 24, thereby realizing the rotation of the second support frame.

[0060] Further, the driving motor 22 can drive the rotating shaft to rotate forward and backward, enabling the second support frame to rotate clockwise and counterclockwise, so as to adjust and disassemble the axle boxes 5 symmetrically arranged at both ends of the wheel set in a mirror image.

[0061] In a preferred embodiment, the driving motor 22 can drive the second support frame to rotate 52° clockwise or 52° counterclockwise.

[0062] Further, to improve the stability of the second support frame, as Figure 1 shown, a number of second support rods 211 are respectively fixed on the surfaces of the two second fixing plates 21 to reinforce the load-bearing capacity of the second fixing plates 21; meanwhile, a connecting rod is arranged between the two second fixing plates 21, and both ends of the connecting rod are respectively connected to the two second fixing plates 21, or both ends of the connecting rod are respectively connected to the second support rods 211 on the two second fixing plates 21, so that the two second fixing plates 21 and the connecting rod form a triangular frame structure, further improving the stability of the second support frame.

[0063] In a preferred embodiment, the second support rods 211 on the upper surface of the horizontally placed second fixing plate 21 form a "field" character structure, reducing the manufacturing cost on the premise of ensuring the load-bearing capacity of the second fixing plate 21. Among them, the second support rods 211 can be made of aluminum alloy material.

[0064] As Figure 1 and Figure 2 shown, the force-breaking disassembly mechanism is fixed on the horizontally placed second fixing plate 21, making the force-breaking disassembly mechanism perpendicular to the second gear 24. The force-breaking disassembly mechanism includes: a clamping jaw part, a third support frame and a force-breaking part. The third support frame is a triangular structure composed of third support rods; and the top end of the third support frame is fixed on the lower surface of the horizontally placed second fixing plate 21, and a vertically placed third fixing plate 33 is arranged at the bottom of the third support frame. Among them, a second connection hole is arranged on the surface of the third fixing plate 33.

[0065] As Figure 1 shown, the clamping jaw part includes: two clamping jaws 32, a cavity 31 and a pneumatic pipeline. The cavity 31 is a cuboid structure, fixed on the lower surface of the horizontally placed second fixing plate 21, and a chute is arranged along the length direction of the lower surface of the cavity 31. The two clamping jaws 32 are respectively arranged on both sides of the chute and can slide close to or away from each other along the chute. The pneumatic pipeline is arranged in the cavity 31, its air inlet end can be filled with gas, and its air outlet ends are respectively connected to the two clamping jaws; by inflating the pneumatic pipeline, the two clamping jaws 32 are made to approach each other along the chute to complete the clamping action; by deflating the pneumatic pipeline, the two clamping jaws 32 are made to move away from each other along the chute to realize the reset of the two clamping jaws 32.

[0066] Furthermore, the gripper portion is applicable to various models of axle boxes 5 (e.g., CRH3 and CR400 split-type long axle boxes), making the device of the utility model more versatile, avoiding the need to replace the gripper portion when disassembling different models of axle boxes 5, and saving time when disassembling axle boxes 5.

[0067] In a preferred embodiment, the gripper is a parallel opening and closing pneumatic gripper with an air cut-off locking function to prevent the axle box 5 from falling off due to a sudden air cut-off in the pneumatic pipeline.

[0068] like Figure 2 As shown, the breaking force unit is fixed to the third fixing plate 33 and includes: a first cylinder 34 and a first push rod. The first cylinder 34 is fixed to the surface of the third fixing plate 33. One end of the first push rod is located at the output end of the first cylinder 34, and the other end passes through the second connecting hole and is provided with a positioning member, so that the positioning member is located below the gripper portion. When the first cylinder 34 is inflated, the first cylinder 34 pushes the first push rod to move outward; after the first cylinder 34 is deflated, the first push rod retracts into the first cylinder 34, completing the reset.

[0069] Furthermore, the positioning element is a cylinder; and the diameter of the positioning element is less than or equal to the diameter of the axle on the wheelset, so that the positioning element only contacts the axle and does not touch the axle box sleeved on the axle.

[0070] Furthermore, the distance that the first cylinder 34 pushes the first push rod to move is greater than the distance between the wheel axle and the positioning component when the first push rod is in the retracted state (i.e., the first cylinder 34 is not inflated). After the first cylinder 34 is inflated, the first push rod can drive the positioning component to apply a thrust to the axle. Since the axle box 5 is fixed by the gripper, the first push rod pushes the axle at this time, causing the axle box 5 to move relative to the axle, thereby detaching the axle box 5 from the axle.

[0071] In a preferred embodiment, the positioning element of the first push rod is a polyurethane rubber top rod.

[0072] Furthermore, the vertical distance between the gripper 32 and the positioning member on the first push rod matches the vertical distance between the top of the axle box 5 and the axle when the axle box 5 is installed on the wheelset, so that the positioning member can contact the axle on the wheelset when the gripper 32 clamps the top of the axle.

[0073] like Figure 4 and Figure 5 As shown, when using the axle box disassembly and overturning device described in this utility model, the operator raises the wheelset 6 with axle box 5 using a lifting turntable and removes the parts on the wheelset 6; as Figure 4As shown, the axle boxes 5 symmetrically arranged on both sides of the wheelset 6 form a certain angle with the plane of the lifting turntable (in one embodiment, the axle box 5 is a CRH3 or CR400 split-type long axle box, and the angle is 52°); the lifting part of the hoist is inserted into the first connecting hole 121, and the hoist and the support plate 12 are fixed together through the fixing hole 122; the hoist is started, and the device of this utility model is lifted for the first time, so that the bottom of the device is off the ground. Reference Figure 3 The drive motor 22 is started, which drives the rotating shaft to rotate, thereby causing the first gear 23 to rotate coaxially with the rotating shaft. Since the first gear 23 is meshed with the second gear 24, the first gear 23 drives the second gear 24 to rotate around the fixed shaft 25, thereby driving the second fixed plate 21 fixed on the surface of the second gear 24 to rotate, realizing the rotation of the second support frame. Since the third support frame is fixed together with the second support frame, the gripper and breaking force part installed on the third support frame rotate simultaneously with the second support frame. After the third support frame rotates clockwise or counterclockwise by a certain angle, the angle between the third support frame and the plane of the lifting turntable is the same as the angle between the disassembled axle box 5 and the plane of the lifting turntable (in the above embodiment, the third support frame needs to rotate 52° clockwise or counterclockwise). The hoist is restarted, and the device described in this utility model is lifted a second time, so that the positioning member of the first push rod in the breaking force section is on the same axis as the axle 61 of the wheelset 6, and the two grippers 32 in the gripper section are positioned on both sides of the top of the axle box 5 (in the above embodiment, the top of the axle box 5 is a compression spring boss), which can be referred to Figure 1 Simultaneously, by inflating the pneumatic pipes of the gripper section, the two grippers 32 move closer to each other along the slide groove, completing the clamping of the gripper section onto the top of the shaft box 5. Then, the drive motor 22 is restarted and reversed, causing the first gear 23 to rotate, which in turn drives the second gear 24 to rotate, thereby rotating the second support frame (in the above embodiment, the third support frame needs to rotate 52° counterclockwise or clockwise), and driving the third support frame to reset; Figure 5 As shown, the third support frame drives the gripper 32 to rotate in the opposite direction, so that the axle box 5 is parallel to the plane of the lifting turntable, preventing the side of the tilted axle box 5 from rubbing against the plane of the lifting turntable during disassembly and thus damaging the axle box 5.

[0074] Subsequently, the first cylinder 34 of the breaking force unit is inflated, causing it to push the first push rod towards the axle 61 of the wheelset 6. Since the distance the first push rod travels is greater than the distance between the axle 61 of the wheelset 6 and the positioning member when the first push rod is retracted, the positioning member can push the axle 61, thereby causing relative movement between the axle 61 and the axle box 5, completing the process of removing the axle box 5 from the axle 61. Then, the first cylinder 34 is deflated, causing the first push rod to retract and controlling the breaking force unit to reset.

[0075] In a preferred embodiment, to further prevent the wheel box 5 from falling off during disassembly, such as... Figure 1 and Figure 2 As shown, the axle box disassembly and force-breaking overturning device of this utility model further includes: two protective mechanisms, which are symmetrically arranged on both sides of the third support frame.

[0076] Specifically, each of the protective mechanisms includes: an extension plate 41, a second cylinder 42, a second push rod 43, and a protective baffle 44. The extension plate 41 is disposed at the edge of the horizontally disposed second fixed plate 21 to widen the width of the second fixed plate 21. The second cylinder 42 is vertically fixed to the bottom surface of the extension plate 41, and the second cylinder 42 is a rotary cylinder. The top end of the second push rod 43 is connected to the output end of the second cylinder 42, and the second cylinder 42 can drive the second push rod 43 so that the second push rod 43 can extend vertically downward while rotating 90°. The protective baffle 44 is horizontally disposed below the second fixed plate 21, and its upper surface is fixed to the bottom end of the second push rod 43.

[0077] Furthermore, the two second cylinders 42 work synchronously and output opposite rotational torque forces, causing the second push rods 43 in the two protective mechanisms to rotate in opposite directions.

[0078] Furthermore, in the initial state, the protective baffles 44 of the two protective mechanisms are positioned opposite each other towards the gripper 32, so that when the second push rod 43 is in the retracted state, the axes of the long sides of the two protective baffles 44 are on the same straight line. After the two second cylinders 42 are activated, they drive the two second push rods 43 to move the two protective baffles 44 downwards and rotate them 90° in the opposite direction, so that the two protective baffles 44 rotate from directly below the second fixed plate 21 to directly below the extension plate 41. When the gripper 32 clamps the axle box 5, the two protective baffles 44 are in contact with the bottom of the axle box 5 to prevent the axle box 5 from falling off. At this time, the axes of the long sides of the two protective baffles 44 are parallel, which can be referenced. Figure 1 and Figure 2 The position of the central protective baffle 44 effectively saves the space occupied by the device when it is not in operation.

[0079] After the axle box 5 separates from the axle of the wheelset 6, the two protective mechanisms start operating synchronously. In each protective mechanism, the second cylinder 42 activates, pushing the second push rod 43 downwards and rotating it 90°, thereby rotating the protective baffle 44 90°. Because the second cylinders 42 in the two protective mechanisms output opposite rotational torque forces, the protective baffle 44, fixed at the bottom of the second push rod 43, rotates from its relatively positioned state towards the gripper 32, allowing the protective baffle 44 to contact the bottom of the axle box 5, further preventing the axle box 5 from falling. When the hoist moves the device and its clamping axis to the transport line, the protective mechanism is manually reset by the operator. At this time, the second cylinder 42 controls the second push rod 43 to rotate 90° in the opposite direction and retract; then, the pneumatic pipeline is released, causing the two grippers 32 to move in the opposite direction along the groove of the cavity, completing the reset of the clamping part and simultaneously separating the axle box 5 from the device.

[0080] In summary, the device of this utility model achieves relative rotation of the first support frame and the second support frame by setting the first gear and the second gear to mesh and connect. By rotating the second support frame, the gripper 32 can clamp the tilted axle box. By rotating the second support frame in the opposite direction, the axle box is straightened, thereby achieving automatic flipping of the axle box, reducing the labor intensity of workers and improving the efficiency of wheelset disassembly.

Therefore, the scope of protection of the present invention should be defined by the appended claims.
