DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will be further described below with reference to the drawings.

[0024] The retaining key of a railway freight car is a small component between the side frame bottom of a railway freight car bogie and the wheel set. The retaining key is installed in the side frame guide of the bogie through a retaining key bolt. When the bogie is subjected to tensile force, the side frame and the wheel set can be connected together by means of the retaining key to prevent the wheel set from falling off.

[0025] When the wheelset needs to be repaired, the fasteners of the retaining key need to be loosened, and then the retaining key is retracted to release the limit of the wheelset by the retaining key. In the actual production process, due to rust and other reasons, the fasteners of the retaining key are stuck in the disassembly device during disassembly or cannot be disassembled due to rusting, etc., and special tools need to be used for cutting. However, since the disassembly position of the retaining key is relatively low and it is not easy to be discovered in time, it is easy to cause damage to the disassembly equipment, so that the fasteners of the retaining key cannot be effectively loosened, affecting the disassembly operation of the retaining key and the production efficiency of wheelset repair.

[0026] The utility model provides a retaining key loosening assembly for a wheelset and a retaining key disassembly device for a wheelset, which can timely detect the situation that the fasteners of the retaining key are stuck in the retaining key disassembly device of the wheelset during the loosening process, effectively avoid the damage of the retaining key disassembly device of the wheelset, and effectively improve the disassembly efficiency of the retaining key and the repair efficiency of the wheelset.

[0027] Figure 1 It is a schematic structural diagram of a retaining key loosening assembly for a wheelset in an embodiment of the utility model. As Figure 1 shown, an embodiment of the present application provides a retaining key loosening assembly for a wheelset. The retaining key loosening assembly 100 of the wheelset includes a driving assembly 10 and a sleeve 20. The sleeve 20 is configured to be cooperatively connected with the fasteners of the retaining key to loosen the retaining key and the fasteners. The driving assembly 10 is connected to the sleeve 20, and the driving assembly 10 is configured to drive the sleeve 20 to rotate along the axial direction of the sleeve and drive the fasteners to rotate so as to loosen the retaining key and the fasteners. A first alarm assembly 30 is arranged on the sleeve 20, and the first alarm assembly 30 is configured to give an alarm prompt when the driving member cannot drive the sleeve 20 to disengage from the axially cooperatively connected fasteners.

[0028] According to the retaining key loosening assembly 100 of the wheelset in the application embodiment, during use, the sleeve 20 is cooperatively connected with the fasteners of the retaining key, and the driving assembly 10 drives the sleeve 20 to rotate forward or backward so that the sleeve 20 drives the fasteners to rotate synchronously to loosen the retaining key and the fasteners. When the retaining key and the fasteners are loosened, the sleeve 20 moves along its own axial direction and disengages from the fasteners. When the sleeve 20 cannot disengage from the fasteners along its own axial direction, the first alarm assembly 30 arranged on the sleeve 20 can give an alarm prompt in time, so that the staff can timely detect the situation that the sleeve 20 is stuck with the fasteners and make corresponding treatments, effectively avoiding damage caused by the continuous operation of the retaining key loosening assembly 100 of the wheelset, and effectively improving the disassembly efficiency of the retaining key and the repair efficiency of the wheelset.

[0029] As Figure 1As shown, in some embodiments, the key blocking release assembly 100 further includes a sensor assembly 40 and a second alarm assembly. The sensor assembly 40 is connected to the drive assembly 10, and the sensor is used to detect the torque output by the drive assembly 10. The second alarm assembly is electrically connected to the sensor assembly 40, and the second alarm assembly is configured to give an alarm prompt when the sensor assembly 40 detects that the torque exceeds a preset value.

[0030] It should be noted that during the process of disassembling the key blocking of the wheel set, due to reasons such as rusting and jamming of the fasteners of the key blocking, the key blocking release assembly 100 loosens the fasteners. Other tools are needed to cut the jammed fasteners. However, during the process of releasing the key blocking, the field of vision is limited and it is basically a blind operation, and it is even more impossible to detect the jammed nuts in time. Therefore, in this embodiment, the key blocking release assembly 100 further includes a sensor assembly 40. The sensor assembly 40 is connected to the drive assembly 10 and is used to detect the torque output by the drive assembly 10 when the drive sleeve 20 rotates. When the sensor assembly 40 detects that the torque output by the drive assembly 10 is greater than the preset value, the second alarm assembly electrically connected to the sensor assembly 40 gives an alarm prompt, enabling the staff to timely discover the fasteners jammed due to rusting and other reasons and perform corresponding processing, improving the efficiency of key blocking disassembly and the efficiency of wheel set maintenance.

[0031] As Figure 2 shown, in some embodiments, the outer sleeve 21 includes a first cavity portion Q1 and a second cavity portion Q2 that are sequentially connected to each other along the axial direction. The inner sleeve 22 is sleeved on the first cavity portion Q1. The inner sleeve 22 is provided with a through groove H that communicates with the second cavity portion Q2. Along the radial direction of the inner sleeve 22, the length dimension of the through groove H is greater than the inner diameter dimension of the inner sleeve 22, and the inner diameter dimension of the second cavity portion Q2 is not less than the length dimension of the through groove H.

[0032] It should be noted that in the related art, after the fasteners of the key blocking, such as bolts and nuts, fasten and fix the key blocking, some rivets and retaining pins are also provided on the bolts to prevent the key blocking nut from falling off after excessive loosening. However, the rivet specifications are not completely unified. During the process of sleeving the inner sleeve 22 onto the bolt of the key blocking, the rivets may get stuck on the inner wall of the inner sleeve 22, causing the inner sleeve 22 to malfunction. In this embodiment, a through groove H is provided in the inner sleeve 22. Along the radial direction of the inner sleeve 22, the length dimension of the through groove H is greater than the inner diameter dimension of the inner sleeve 22, enabling different specifications of rivets or retaining pins on the bolt to pass through, so that the inner sleeve 22 can be connected and cooperate with the nut. And when the driving member drives the inner sleeve 22 to rotate to loosen the nut, since the inner diameter dimension of the second cavity portion Q2 is not less than the length dimension of the through groove H, the rivets extending into the second cavity portion Q2 of the outer sleeve 21 rotate in the second cavity portion Q2 without affecting the loosening of the key blocking nut by the inner sleeve 22.

[0033] AsFigure 2-3 As shown, in some embodiments, the sleeve 20 includes an outer sleeve 21, an inner sleeve 22, and a sleeve ring 23 for triggering the switch 32. The outer sleeve 21 is connected to the drive assembly 10. The inner sleeve 22 is coaxially sleeved on the outer sleeve 21 and is configured to be at least partially cooperatively connected to the fastener of the retaining key. Axially, the inner sleeve 22 can slide axially relative to the outer sleeve 21. The sleeve ring 23 is connected to the opening edge of the outer sleeve 21 and is configured to axially limit the inner sleeve 22. The trigger switch 32 of the first alarm assembly 30 is installed on at least one of the end face of the inner sleeve 22 facing the sleeve ring 23 and the end face of the sleeve ring 23 facing the inner sleeve 22. Axially, the inner sleeve 22 can slide relative to the outer sleeve 21 and abut against the sleeve ring 23, so that the trigger switch 32 of the first alarm assembly 30 is triggered to give an alarm.

[0034] It should be noted that the inner sleeve 22 is sleeved on the outer sleeve 21 and cannot rotate relative to the outer sleeve 21 axially. While the drive assembly 10 drives the outer sleeve 21 to rotate axially, the outer sleeve 21 drives the inner sleeve 22 to rotate synchronously. The inner sleeve 22 can slide axially relative to the outer sleeve 21. However, since the sleeve ring 23 is connected to the opening edge of the outer sleeve 21, when the inner sleeve 22 slides axially along the outer sleeve 21, the sleeve ring 23 axially limits the inner sleeve 22, that is, the inner sleeve 22 cannot slide out of the opening of the outer sleeve 21 axially.

[0035] In this embodiment, the inner sleeve 22 is sleeved on the outer sleeve 21, and the inner sleeve 22 can slide relative to the outer sleeve 21 axially. When the key removal device needs to remove the axle journal key, the key loosening assembly 100 first loosens the fastener of the key. When loosening the fastener, at least part of the inner sleeve 22 cooperates with the fastener, and the driving assembly 10 drives the outer sleeve 21 to rotate axially. While the outer sleeve 21 rotates, it drives the inner sleeve 22 to rotate axially, so that the inner sleeve 22 loosens the fastener. After the key loosening assembly 100 loosens the fastener of the key, the key is loosened, and the key loosening assembly 100 disengages from the fastener. If the fastener is stuck to the inner sleeve 22 due to rust or other reasons and the inner sleeve 22 cannot be disengaged from the fastener, when the key loosening assembly 100 disengages from the fastener, the fastener will drive the inner sleeve 22 to slide axially relative to the outer sleeve 21 towards the end close to the sleeve ring 23. Since the trigger switch 32 electrically connected to the first alarm assembly 30 is installed on at least one of the end face of the inner sleeve 22 facing the sleeve ring 23 and the end face of the sleeve ring 23 facing the inner sleeve 22, when the inner sleeve 22 abuts against the sleeve ring 23, the first alarm assembly 30 is triggered to be turned on, and then the first alarm assembly 30 gives an alarm prompt, enabling the staff to timely detect the situation where the sleeve 20 is stuck with the fastener and take corresponding measures, effectively avoiding damage caused by the continuous operation of the key loosening assembly 100 of the axle journal and effectively improving the key removal efficiency and the overhaul efficiency of the axle journal.

[0036] As Figure 2 , Figure 4 shown, in some embodiments, the sleeve 20 further includes an elastic member M, and the elastic member M is disposed between the end face of the inner sleeve 22 facing the sleeve ring 23 and the end face of the sleeve ring 23 facing the inner sleeve 22.

[0037] In this embodiment, an elastic member M is disposed between the end face of the inner sleeve 22 facing the sleeve ring 23 and the end face of the sleeve ring 23 facing the inner sleeve 22. The elastic member M provides a thrust force towards the inner sleeve 22 direction to limit the axial sliding of the inner sleeve 22 relative to the outer sleeve 21.

[0038] In some embodiments, there are multiple elastic members M, and the multiple elastic members M are evenly distributed along the circumferential direction of the inner sleeve 22.

[0039] In this embodiment, the multiple elastic members M are independent of each other, and the multiple independent elastic members M are evenly distributed along the circumferential direction of the inner sleeve between the end face of the inner sleeve 22 facing the sleeve ring 23 and the end face of the sleeve ring 23 facing the inner sleeve 22, making the circumferential force on the inner sleeve 22 uniform.

[0040] As Figure 3As shown, in some embodiments, the first alarm component 30 includes a trigger switch 32 and a warning light 31. The trigger switch 32 is disposed on at least one of the end face of the inner sleeve 22 facing the sleeve ring 23 and the end face of the sleeve ring 23 facing the inner sleeve 22. The warning light 31 is electrically connected to the trigger switch 32, and the warning light 31 is disposed on the outer side wall of the outer sleeve 21.

[0041] In this embodiment, the first alarm component 30 includes a trigger switch 32 and a warning light 31, and the warning light 31 is electrically connected to the trigger switch 32. When the fastener jams in the inner sleeve 22 and the key blocking release component 100 drives the inner sleeve 22 to slide relative to the outer sleeve 21 when disengaging from the fastener, the inner sleeve 22 abuts against the sleeve ring 23 provided at the opening edge of the outer sleeve 21, thereby triggering the trigger switch 32 provided between the inner sleeve 22 and the sleeve ring 23, so that the warning light 31 electrically connected to the trigger switch 32 is turned on, enabling the staff to observe the warning signal of the warning light 31 for corresponding processing.

[0042] In some alternative embodiments, the first alarm component 30 further includes a warning horn, and the trigger switch 32 is electrically connected to the warning horn. When the trigger switch 32 is triggered and turned on, at least one of the warning light 31 and the warning horn 3 can give an alarm prompt.

[0043] In some embodiments, the key blocking release component 100 of the wheel set further includes a base and a multi-axis robotic arm. The multi-axis robotic arm is connected to the key blocking release component 100. The base is connected to the multi-axis robotic arm. The base is provided with a control system. The second alarm component and the driving component 10 are both electrically connected to the control system, and the control system can send a prompt to the terminal server or control the driving component 10 to stop working according to the alarm prompt of the second alarm component.

[0044] In this embodiment, the multi-axis robotic arm can drive the key blocking release component 100 to release the key, so that the key blocking release component 100 can work even in extreme positions. When the fastener of the key is rusted and stuck, causing the driving component 10 to output a torque exceeding the preset value, the second alarm component emits an alarm signal. Since the control system provided on the base is electrically connected to the second alarm component and the driving component 10 respectively, after receiving the alarm signal of the second alarm component, the control system sends a prompt to the terminal server or controls the driving component 10 to stop working, avoiding damage to the key blocking release component 100.

[0045] In some embodiments, the key blocking release component 100 further includes an image detection component. The image detection component is connected to the multi-axis robotic arm, the image detection component is electrically connected to the control system, and the image detection component is used to detect the signal when the warning light 31 lights up.

[0046] In this embodiment, the image detection component connected to the multi-axis robotic arm can detect the signal that causes the warning light 31 to turn on due to the fastener being rusted and stuck inside the inner sleeve 22. The image detection component transmits the signal to the control system, which can control the driving component 10 to stop working or control the driving component 10 to rotate forward or backward quickly. By repeatedly impacting with the rotational inertia, the fastener stuck inside the inner sleeve 22 is separated from the inner sleeve 22, avoiding the damage of the retaining key release component 100.

[0047] The present utility model also provides a retaining key disassembly device for a wheel set. The retaining key disassembly device for a wheel set includes the retaining key release component 100 of any of the foregoing embodiments, and has all the beneficial effects of the retaining key release component 100 in any of the foregoing embodiments. The specific structure and beneficial effects of the retaining key release component 100 will not be elaborated herein one by one.

[0048] Although the present utility model has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
