Description

Technical Field

[0001] This invention relates to the field of bogie disassembly technology, and specifically provides a stop disassembly system. Background Technology

[0002] The key in a railway freight car is a small wedge-shaped component near the bearing on the bogie. It is installed in the side frame guide frame and, when the bogie is under tension, the key connects the side frame to the wheelset to prevent the wheelset from falling off.

[0003] When inspecting and maintaining bogies, the bolts on the key need to be loosened, and then the key needs to be retracted to disengage it from the wheelset and release its limiting position. Currently, to reduce the labor intensity of workers, equipment capable of automatically disassembling the key has been developed, such as the key disassembly device for wheelsets in Chinese patent CN223044003U. This device includes a multi-axis robotic arm, a screwing component for loosening fasteners, and a key retraction component for pushing the loosened key away from its limiting position, thus achieving automated key disassembly. However, the core screwing component used in this device is a pre-made electric wrench, which is expensive and difficult to procure, preventing large-scale production. The main problem is that when using this structure to loosen bolts, the entire device is prone to displacement due to reaction force, resulting in poor actual loosening effect. The only solution is to increase the overall size of the equipment to provide sufficient weight and torque to counteract the reaction force generated by the wrench, which significantly increases equipment costs. Therefore, there is an urgent need for a device for disassembling key components that can avoid the impact of the reaction force on the equipment when loosening the key bolts. Summary of the Invention

[0004] Firstly, to address the aforementioned problems, this invention provides a system for automatically disassembling a retaining component that prevents displacement due to reaction force when loosening the retaining key bolt. The specific technical solution is as follows:

[0005] A key removal system includes an installation arm, one end of which is connected to a lifting mechanism, and the other end is provided with a key pushing mechanism and a bolt loosening mechanism with a nut sleeve. The bolt loosening mechanism controls the nut sleeve to loosen the key bolt, and the key pushing mechanism pushes the key back. The key pushing mechanism can rotate around the axis of the nut sleeve. The bolt loosening mechanism includes a reverse thrust unit, which always abuts against the bogie when the nut sleeve is in operation.

[0006] In this scheme, the bolt loosening mechanism is used to loosen the bolts and nuts of the stop, and then push the stop key away through the key pusher mechanism to release the lock on the wheelset. When the bolt loosening mechanism drives the nut on the stop key bolt to rotate through the nut sleeve, since the reverse thrust unit always abuts against the bogie, the reaction force of the entire bolt loosening structure is transmitted to the bogie, which can effectively prevent the entire equipment from shifting and ensure that the bolt loosening mechanism can stably and accurately loosen the stop key bolt.

[0007] Preferably, the bolt loosening mechanism includes a first motor and a hollow shaft, the mounting arm is rotatably sleeved on the hollow shaft, a rotating shaft coaxially disposed in the hollow shaft and drivenly connected to the first motor, the nut sleeve is drivenly connected to the rotating shaft and extends out of the hollow shaft, and the reverse thrust unit is fixedly disposed on the hollow shaft.

[0008] In this design, the mounting arm is sleeved on the hollow shaft and can rotate around the hollow shaft. This prevents the reaction force experienced by the bolt loosening mechanism during operation from being transmitted to the lifting mechanism and subsequent equipment through the mounting arm, effectively ensuring that the foundation of the entire equipment will not shift or slide.

[0009] Secondly, to minimize the structure at the nut sleeve and ensure that the nut sleeve can smoothly extend into the underside of the vehicle and fit the nut of the key while avoiding obstruction from other structures, preferably, the loosening mechanism also includes a transmission frame. The first motor and the rotating shaft are respectively disposed at both ends of the transmission frame. The angle between the transmission frame and the mounting arm at the hollow shaft is an acute angle. A motor sleeve is sleeved on the outside of the first motor. The motor sleeve and the hollow shaft are fixedly disposed on the transmission frame. A buffer unit and a limiting tension spring are disposed on the side of the mounting arm near the transmission frame. The limiting tension spring is used to limit the size of the angle formed between the mounting arm and the transmission frame and the hollow shaft.

[0010] In this scheme, by separating the first motor and the rotating shaft, the first motor is prevented from obstructing the nut sleeve from extending into the bottom of the bogie. At the same time, since the first motor and the rotating shaft are not on the same axis, when the rotating shaft is driven to rotate by the first motor, the reaction force at the rotating shaft will cause the transmission frame to rotate around the hollow shaft axis in the opposite direction to the rotation of the rotating shaft. At this time, the rotation of the rotating shaft in this direction can be restricted by the push unit abutting against the bogie.

[0011] Furthermore, to prevent interference between the bogie and other structures when the nut sleeve is fitted onto the nut from below, the thrust reverser unit, when the nut sleeve is not in operation, is prevented from contacting the bogie by the pull of a limit spring. The limit spring also ensures that after the nut sleeve releases the key nut, the transmission frame rotates towards the mounting arm under the tension of the limit spring, facilitating the smooth removal of the bolt loosening mechanism. The buffer unit on the mounting arm ensures that after the limit spring pulls the transmission frame to rotate, the first motor section does not rigidly collide with the mounting arm.

[0012] Thirdly, in order to ensure that the thrust reverser can abut against the bogie regardless of whether the key is removed from the front or rear bogie, preferably, the thrust reverser includes a first abutment and a second abutment. The first abutment and the second abutment are symmetrically arranged around the axis of the hollow shaft. The angle between the first abutment and the mounting arm at the hollow shaft is an acute angle. The transmission frame is located between the first abutment and the mounting arm.

[0013] In this scheme, through the centrally symmetrical first and second abutment members, regardless of which direction the stop is released, after the transmission frame is subjected to force and rotates initially, it can be ensured that at least one abutment member can abut against the bogie, limiting the continued rotation of the transmission frame. Furthermore, since the transmission frame is located between the first abutment member and the mounting arm, it can also prevent the bolt loosening mechanism from directly colliding with the bogie.

[0014] Because loosening the key bolt requires significant torque, these pre-made electric wrenches are prone to damage due to excessive load, rendering existing key removal devices obsolete. Furthermore, the key retraction assembly requires multiple motors to push the key, resulting in a large and heavy device, leading to a series of uneconomical problems. Therefore, chain drive is preferable, ensuring that the first motor can transmit sufficient torque to the rotating shaft, maintaining a certain distance between the first motor and the rotating shaft, while also being lighter than gear drives or screw drives.

[0015] Preferably, one end of the rotating shaft is a sleeve structure, the nut sleeve is slidably disposed in the rotating shaft, a first elastic member is disposed between the rotating shaft and the sleeve, the first elastic member provides the nut sleeve with a force away from the rotating shaft, a guide ridge is disposed on the outer wall of the sleeve, and a concave rail adapted to the guide ridge is disposed on the inner wall of the rotating shaft.

[0016] In this design, when the mounting arm is lifted upward by the lifting mechanism, the nut sleeve can slide towards the rotation axis after encountering a certain resistance, thus preventing the nut sleeve from being damaged by collision due to inaccurate alignment with the key bolt.

[0017] Preferably, the push key mechanism includes a horizontal push plate and a slider that slides along the length of the horizontal push plate. The slider is pushed by a push unit. One end of the horizontal push plate is rotatably sleeved on the hollow shaft, and the rotation of the horizontal push plate is controlled by a rotation unit set on the mounting arm.

[0018] Preferably, the rotating unit includes a second motor, which is fixedly mounted on the upper surface of the mounting arm. The second motor drives the drive shaft downward through the mounting arm via a reducer and is connected to a horizontal gear. One end of the horizontal push plate sleeved on the hollow shaft is a gear ring structure, which meshes with the horizontal gear.

[0019] In this design, a rotating unit mounted on the mounting arm controls the key-pushing mechanism, allowing for the removal of both front and rear keys with a single device. Simultaneously, the pushing unit causes a sliding component to push the loosened key towards the center of the bogie from a distance, thus retracting the key. Furthermore, by simply adjusting the angle between the pushing plate and the support arm via the drive mechanism to ensure accurate positioning of the horizontal pushing module, keys of various specifications can be pushed, thereby retracting the loosened key.

[0020] Preferably, the slider includes a top block and a slider that is drivenly connected to the pusher unit. The slider is a cylindrical structure with an upward opening. The top block is vertically slidably disposed in the slider. A second elastic member is disposed between the top block and the slider. The second elastic member provides a force to the top block away from the slider. A stop is disposed on the top of the top block. A horizontal lifting plate extends from the side of the stop facing the hollow shaft.

[0021] In this design, before loosening the bolts on the stop, the mounting arm is lifted upwards via a lifting mechanism to allow the key nut to enter the nut sleeve. During the lifting process, the stop block receives pressure, causing the top block to be pressed down by the hub or other structure, resulting in the contraction of the elastic component. After the loosening action is completed, as the slider is pushed, the horizontal lifting plate can be inserted between the key and the bogie, and vertically move away from the obstruction of the hub or other structure. The pushing unit provides horizontal thrust, and the second elastic component provides a force that holds the key and applies an upward force to it, allowing the key to be retracted more easily.

[0022] Preferably, it also includes a vision recognition unit, which includes a vision camera facing the nut sleeve and a controller that is communicatively connected to the vision camera. The controller can automatically control the actions of the lifting mechanism, the pushing mechanism and the loosening mechanism, while the vision camera is used to identify the position of the nut sleeve and the key bolt.

[0023] The beneficial effects of this invention are:

[0024] In this invention, a reverse thrust unit is set in the bolt loosening mechanism. When the bolt loosening mechanism drives the nut on the key bolt to rotate through the nut sleeve, the reverse thrust unit always abuts against the bogie, so that the reaction force on the entire bolt loosening structure is transmitted to the bogie. This can effectively prevent the entire equipment from shifting, ensure that the bolt loosening mechanism can loosen the key bolt stably and accurately, effectively improve the service life of the entire equipment, and also allow the entire equipment to be designed to be smaller and lighter.

Detailed Implementation

[0032] The technical solution of the present invention will be clearly and completely described in conjunction with the accompanying drawings and through specific implementation methods of the embodiments of the present invention.

[0033] Example 1:

[0034] A key removal system, such as Figure 1 and Figure 2 As shown, the bogie includes a mounting arm 1, one end of which is connected to a lifting mechanism 2, and the other end is provided with a push key mechanism 3 and a bolt loosening mechanism 4 with a nut sleeve 41. The push key mechanism 3 can rotate around the axis of the nut sleeve 41. The bolt loosening mechanism 4 includes a reverse thrust unit 5, which always abuts against the bogie when the nut sleeve 41 is working.

[0035] The lifting mechanism 2 connected to the mounting arm 1 is a robotic arm with multiple degrees of freedom on the robot car. It can control the tethered structure to perform vertical lifting and lowering movements, and can also move the system along with it. Figure 4 As shown, the bolt loosening mechanism 4 in this embodiment includes a first motor 42 and a hollow shaft 43. The mounting arm 1 is rotatably sleeved on the hollow shaft 43. A rotating shaft 44, which is driven and connected to the first motor 42, is coaxially arranged in the hollow shaft 43. The nut sleeve 41 is driven and connected to the rotating shaft 44 and extends out of the hollow shaft 43. The counter-thrust unit 5 is fixedly mounted on the hollow shaft 43. The mounting arm 1, sleeved on the hollow shaft 43, can rotate around the hollow shaft 43, ensuring that the reaction force received by the bolt loosening mechanism 4 during operation is not transmitted to the lifting mechanism 2 and subsequent equipment through the mounting arm 1, effectively preventing displacement and slippage of the foundation of the entire equipment.

[0036] In this scheme, the bolt loosening mechanism 4 is used to loosen the bolts and nuts of the stop, and then push the stop key away through the key pusher mechanism 3 to release the lock on the wheelset. When the bolt loosening mechanism 4 drives the nut on the stop key bolt to rotate through the nut sleeve 41, since the reverse thrust unit 5 is always in contact with the bogie, the reaction force of the entire bolt loosening structure is transmitted to the bogie, which can effectively prevent the entire equipment from shifting and ensure that the bolt loosening mechanism 4 can stably and accurately loosen the stop key bolt.

[0037] Furthermore, in order to minimize the structure at the nut sleeve 41 and ensure that the nut sleeve 41 can smoothly extend into the bottom of the vehicle and fit the nut of the key, avoiding obstruction from other structures, the bolt loosening mechanism 4 also includes a transmission frame 45, with the first motor 42 and the rotating shaft 44 respectively located at both ends of the transmission frame 45.

[0038] Specifically, since the first motor 42 and the rotating shaft 44 are not on the same axis and are a certain distance apart, the torque output by the first motor 42 can be transmitted to the rotating shaft 44 through chain drive, belt drive, gear drive, etc. In this embodiment, chain drive is preferred. Figure 2 and Figure 3 As shown, both the output shaft of the first motor 42 and the rotating shaft 44 are provided with horizontal rotating teeth 410. The two horizontal rotating teeth 410 are fitted with a transmission chain 411, which drives the motor through the chain 411. This ensures that the first motor 42 is at a certain distance from the rotating shaft 44, while also being lighter than gear transmission, screw transmission, etc.

[0039] It should be noted that when the first motor 42 drives the rotating shaft 44 to rotate, the reaction force on the rotating shaft 44 will cause the transmission frame 45 to rotate around the axis of the hollow shaft 43 in the opposite direction to the rotation of the rotating shaft 44. Figure 2As shown, the rotation direction of the nut sleeve 41 is clockwise from this perspective, so the transmission frame 45 is subjected to force and rotates counterclockwise around the hollow shaft 43. Under this condition, taking the rotation direction of the hollow shaft 43 as the forward direction, the transmission frame 45 is set on the rear mounting arm, and the angle between the transmission frame 45 and the mounting arm 1 at the hollow shaft 43 is an acute angle. The reverse thrust unit 5 includes a first abutting member 51 and a second abutting member 52, which are symmetrically arranged around the axis of the hollow shaft 43. The first abutting member 51 and the second abutting member 52 can use baffles, tubes, profiles, etc. with sufficient length and strength, preferably as follows: Figure 2 A more reliable triangular plate structure is used. The angle between the first abutment 51 and the mounting arm 1 at the hollow shaft 43 is an acute angle, and the transmission frame 45 is located between the first abutment 51 and the mounting arm 1. This ensures that no matter which direction the stop is released, after the transmission frame 45 is initially rotated under force, at least one abutment can abut against the bogie or wheel, thereby limiting the continued rotation of the transmission frame 45. Furthermore, the fact that the transmission frame 45 is located between the first abutment 51 and the mounting arm 1 also prevents the bolt loosening mechanism 4 from directly colliding with the bogie or wheel.

[0040] Furthermore, a motor sleeve 46 is fitted around the first motor 42. The motor sleeve 46 and the hollow shaft 43 are fixedly mounted on the transmission frame 45. A buffer unit 47 and a limiting spring 48 are provided on the side of the mounting arm 1 near the transmission frame 45. One end of the limiting spring 48 is connected to the mounting arm 1, and the other end is connected to the transmission frame 45, which limits the angle formed between the mounting arm 1, the transmission frame 45, and the hollow shaft 43. The pulling of the limiting spring 48 prevents the thrust reverser 5 from contacting the bogie. The limiting spring 48 also ensures that after the nut sleeve 41 loosens the key nut, the transmission frame 45 rotates towards the mounting arm 1 under the tension of the limiting spring 48, facilitating the easy removal of the bolt loosening mechanism 4. The buffer unit 47 on the mounting arm 1 can be a rubber pad, silicone pad, spring, or other structure that ensures that after the limiting spring 48 pulls the transmission frame 45 to rotate, the first motor 42 will not rigidly collide with the mounting arm 1.

[0041] In this embodiment, the specific loosening process is as follows: After placing the nut sleeve 41 below the target key bolt, the lifting mechanism 2 lifts the entire loosening mechanism 4, causing the nut sleeve 41 to move upward and fit onto the nut on the key bolt; at this time, the transmission frame 45 is pulled by the limiting tension spring 48, the buffer unit 47 abuts against the motor sleeve 46 on the transmission frame 45, and the reverse thrust unit 5 does not contact the rotating frame; when the first motor 42 drives the nut sleeve 41 to rotate, the entire loosening structure is subjected to a reaction force, and the transmission frame 45 is forced away from the mounting arm 1 until the first abutment 51 or the second abutment 52 abuts against the bogie as the transmission frame 45 rotates. The first abutment 51 or the second abutment 52 transmits the reaction force to the bogie and cancels out the force, allowing the nut sleeve to rotate normally to loosen the nut. After loosening, the reaction force on the loosening structure is very small, at which point the limiting tension spring 48 pulls the transmission frame 45 back, causing the reverse thrust unit 5 to leave the abutment state. After the loosening is completed, subsequent operations can be performed.

[0042] Example 2:

[0043] Based on Example 1, such as Figure 3 As shown, one end of the rotating shaft 44 is a sleeve structure, and the nut sleeve 41 is slidably disposed in the rotating shaft 44. A first elastic member 412 is disposed between the rotating shaft 44 and the sleeve. The first elastic member 412 is preferably a spring. The first elastic member 412 provides the nut sleeve 41 with a force away from the rotating shaft 44. A guide ridge 413 is provided on the outer wall of the sleeve, and a concave rail adapted to the guide ridge 413 is provided on the inner wall of the rotating shaft 44. It should be noted that a limiting mechanism is also provided between the rotating shaft 44 and the sleeve, such as a limiting stop bar set at the extreme position of the upward sliding of the nut sleeve 41, to prevent the first elastic member 412 from completely pushing the nut sleeve 41 out of the slider 322.

[0044] When the mounting arm 1 is lifted upward by the lifting mechanism 2, the nut sleeve 41 can slide towards the rotating shaft 44 after encountering a certain resistance, thus avoiding the nut sleeve 41 from being damaged by collision due to not being accurately aligned with the key bolt.

[0045] Example 3:

[0046] Based on the above embodiment one, as follows Figure 3 As shown, a specific push key mechanism 3 is provided. The push key mechanism 3 includes a horizontal push plate 31 and a slider 32 that slides along the length of the horizontal push plate 31. The slider 32 is pushed by a push unit 36. The push unit 36 ​​includes, but is not limited to, using a telescopic cylinder, an electric push rod, etc. One end of the horizontal push plate 31 is rotatably sleeved on the hollow shaft 43, and the rotation of the horizontal push plate 31 is controlled by a rotation unit set on the mounting arm 1.

[0047] The rotating unit includes a second motor 33, such as... Figure 4 As shown, the second motor 33 is fixedly mounted on the upper surface of the mounting arm 1. The second motor 33 drives the drive shaft downward through the mounting arm 1 via a reducer and is connected to a horizontal gear 34. One end of the horizontal push plate 31, which is sleeved on the hollow shaft 43, is a gear ring 35 structure, which meshes with the horizontal gear 34.

[0048] When unloading the stoppers, whether it's the front wheel stopper or the rear wheel stopper, the push is made from the wheel itself towards the center of the bogie. Therefore, as long as the pushing direction of the horizontal push plate 31 is accurate, the stopper can be retracted. Thus, by controlling the rotation of the push plate in the pusher mechanism 3 through the rotation unit on the mounting arm 1, one device can disassemble both the front and rear stops. Simultaneously, the pusher unit 36 ​​causes the slider 32 to push the loosened stopper towards the center of the bogie from a distance, thereby retracting the stopper. Furthermore, by simply adjusting the angle between the push plate and the support arm through the drive mechanism to ensure accurate pushing of the horizontal pusher module, stops of various specifications can be pushed, thus completing the retraction of the loosened stopper.

[0049] Specifically, the slider 32 includes a top block 321 and a slider 322 that is connected to the pushing unit 36. The slider 322 is a cylindrical structure with an upward opening. The top block 321 is vertically slidably disposed in the slider 322, and a roller 326 is disposed in the slider 322. The roller 326 contacts the surface of the top block 321 to reduce the resistance of the top block 321 sliding in the slider 322. A second elastic member 323, such as a spring or an elastic airbag, is provided between the top block 321 and the slider 322. The second elastic member 323 provides a force to the top block 321 away from the slider 322. A stop block 324 is provided on the top of the top block 321. A horizontal lifting plate 325 extends from the side of the stop block 324 facing the hollow shaft 43. Of course, a limiting mechanism is also provided between the slider 322 and the top block 321, such as a limiting stop bar set at the extreme position of the sliding of the top block 321, to prevent the second elastic member 323 from completely pushing the top block 321 out of the slider 322. Before loosening the bolt of the stop member, the mounting arm 1 is lifted upward by the lifting mechanism 2 so that the stop nut can enter the nut sleeve 41. During the lifting process, the stop block 324 receives pressure, causing the top block 321 to be pressed down by the hub or other structures, causing the elastic member to contract. After the bolt release action is completed, during the pushing process of the slider 32, the horizontal lifting plate 325 can be inserted between the stop key and the bogie, and the vertical direction of the top block 321 is no longer obstructed by the hub or other structures. Due to the presence of the second elastic member 323, the top block 321 will continue to move upward. The pushing unit 36 ​​provides horizontal thrust, and the second elastic member 323 provides a force to hold the stop key and apply upward force to the stop key, allowing the stop key to be retracted more easily.

[0050] Based on Embodiment 1, the specific stop retraction process is as follows: In the initial position, the slide 32 is located away from the hollow rotating shaft on the horizontal push plate 31. During the bolt loosening action, before the lifting mechanism 2 raises the mounting arm 1, the horizontal push plate 31 is rotated to the appropriate position via the rotation unit. Generally, the length direction of the horizontal push plate 31 is perpendicular to the length direction of the mounting arm 1, and the horizontal push plate 31 is located closer to the wheel (if the front wheel stop key is being disassembled, it is closer to the front wheel). When the lifting mechanism 2 raises, the top block 321 is compressed by the wheel. During the process of pushing the slide 32, the top block 321 gradually moves upward and towards the control shaft, allowing the horizontal lifting plate 325 to be inserted between the stop key and the bogie. While raising the stop key, the stop is pushed, thereby retracting the stop. After the complete removal of the stop, the sliding 32 returns to its initial position after the lifting mechanism 2 lowers the mounting arm 1. After rotating the horizontal push plate 31 180° via the rotation unit, the other stop on the same side of the bogie can be removed.

[0051] Example 4:

[0052] Based on the above embodiment three, in order to achieve automation of the entire system, this system also includes a controller with data processing capabilities and various sensor components connected to the controller. The controller automatically controls the actions of various actuators, such as the first motor 42, the second motor 33, and the lifting mechanism 2, by receiving signals from the sensor components. Specific sensor components include a vision recognition unit, which includes a vision camera 6 facing the nut sleeve 41. The vision camera 6 is generally located next to the lifting mechanism 2 and is used to identify the positions of the nut sleeve 41 and the key bolt.

[0053] To ensure the accuracy of the rotation unit's control over the horizontal push plate 31, such as... Figures 1 to 4 As shown, the sensor assembly also includes sensing units 7 mounted on the mounting arm 1 and the horizontal push plate 31. The sensing unit 7 can be an angle sensor, a distance sensor, etc. When the horizontal push plate 31 rotates relative to the mounting arm 1 to a set position, the sensing unit 7 transmits a signal to the controller, which then stops the rotation. Preferably, the sensing unit 7 includes photoelectric gates 71 symmetrically arranged on both sides of the mounting arm 1 and trigger plates 72 symmetrically arranged on both sides of the horizontal push plate 31. When the horizontal push plate 31 rotates to the set position on both sides of the mounting arm 1, the trigger plates 72 of the horizontal push plate 31 insert into the photoelectric gates 71, and the photoelectric gates 71 generate a signal, thereby fixing the angle of the horizontal push plate 31 at this time.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
