Description

Technical Field

[0002] In the final stage of maintenance of a medium-voltage switchboard, after all switches are pushed into the compartment, it is necessary to simulate the operation of the switch from the test position to the operating position to verify whether the switch is stuck, whether the movement is flexible, and whether the position indicators of the test position and the working position of the switch are correct, etc. Taking a certain medium-voltage switchboard as an example, it has more than twenty switches.

[0030] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system structures, technologies, etc. are set forth in order to provide a thorough understanding of the embodiments of the present utility model. However, those skilled in the art should clearly understand that the present utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present utility model.

[0031] Figure 1 An operation tooling 1 for a medium-voltage switchboard in an embodiment of the present utility model is shown, which can automatically perform the insertion and extraction of the medium-voltage switchboard switch.

[0032] It should be understood that the medium-voltage switchboard includes a switch panel and a movable switch disposed on the switch panel. The switch has a socket, and when performing the insertion and extraction operations, a rocker that is adapted to the socket on the switch needs to be inserted first. The rocker is rod-shaped, adapted to the socket, and can protrude from the panel of the switch panel. After the rocker is inserted into the socket, the insertion and extraction of the switch can be realized by clockwise and counterclockwise rotation.

[0033] The operating tooling 1 for the medium-voltage switchboard includes a driving component 10, a transmission component 20, a rotary joint 30, and a mounting base 40. Among them, the mounting base 40 can be detachably arranged on the switch panel of the medium-voltage switchboard for mounting components such as the driving component 10. The driving component 10 is arranged on the mounting base 40 and serves as a power source to provide the power for the rocker to rotate. The rotary joint 30 is used to be detachably connected to the rocker, and drives the rocker to rotate through the rotation of the rotary joint 30, thereby indirectly realizing the insertion and extraction of the medium-voltage switchboard switch. The transmission component 20 is respectively connected to the driving component 10 and the rotary joint 30, and is used to transmit the power provided by the driving component 10 and change the transmission direction of the power.

[0034] Specifically, the driving component 10 includes a driving body 11 and an output shaft 12 connected to the driving body 11. The driving body 11 is arranged on the mounting base 40 for outputting power. The output shaft 12 is located on one side of the driving body 11 in the first direction Y, extends along the first direction Y, and can rotate around the first rotation axis L under the drive of the driving body 11. The output shaft 12 is connected to one end of the transmission component 20.

[0035] One end of the rotary joint 30 is detachably connected to the other end of the transmission component 20 and can rotate around the second rotation axis M under the drive of the transmission component 20. The rotary joint 30 extends along the second direction X, and the other end can be detachably connected to the rocker. The second rotation axis M is perpendicular to the switch panel.

[0036] The transmission component 20 is connected between the rotary joint 30 and the output shaft 12. The driving component 10 can drive the rotary joint 30 to rotate through the transmission component 20, and then drive the rocker to rotate to drive the switch to be inserted and extracted.

[0037] It should be understood that the first direction Y is parallel to the plate surface of the switch panel. The second direction X is perpendicular to the plate surface of the switch panel. The extension direction of the second rotation axis M can be regarded as the second direction X. The extension direction of the first rotation axis L can be regarded as the first direction Y.

[0038] It should be understood that the driving component 10 only needs to be able to realize the clockwise rotation and counterclockwise rotation of the output shaft 12, and then can drive the rocker to realize clockwise and counterclockwise rotations, and then can realize the insertion and extraction of the switch.

[0039] In this application, by setting the driving component 10, the rocker can be automatically rotationally driven, and then the insertion and extraction of the switch can be completed without the operator manually rocking the rocker. It can avoid the operator's mechanical repetitive operation of rotating the rocker, greatly reducing the workload of the operator and improving the operation efficiency. At the same time, it also avoids the potential danger of the operator's hand being injured.

[0040] By providing the mounting base 40 in this application, during the process of rocking in and rocking out operations, it is not necessary for the operator to manually hold and control the position of the drive assembly 10. It can be placed on the switch panel, freeing the operator's hands, further reducing the workload of the operator, and improving work efficiency.

[0041] By providing the transmission assembly 20 in this application, while transmitting power and extending the length of the output shaft 12, the transmission direction can be changed, enabling the output shaft 12 that extends along the first direction Y and rotates around the first rotation axis L to, through the transmission of the transmission assembly 20, achieve that the adapter 30 extends along the second direction X and rotates around the second rotation axis M. That is to say, when the mounting base 40 is provided on the switch panel, the transmission assembly 20 can enable the adapter 30 to be connected to the rocker (that is, the switching of the extension direction from the first direction Y to the second direction X), and at the same time, it can also rotate under the drive of the output shaft 12. It realizes placing the operating tool 1 for the medium-voltage switchboard on the switch panel, freeing the operator's hands, and at the same time enabling the rocking in and rocking out operations of the switch.

[0042] The setting positions and connection methods of the various components in this application can also save the operating space and realize the miniaturization of the operating tool 1 for the medium-voltage switchboard.

[0043] It should be understood that the drive assembly 10 can adopt various existing devices such as motors, and no specific limitations are made here.

[0044] In some embodiments, the transmission assembly 20 includes a worm wheel 23 and a worm 22. They are in meshing transmission to realize the transmission of power.

[0045] Specifically, one end of the worm 22 is connected to the output shaft 12 of the drive assembly 10, and they are coaxially arranged (the axes of both can be regarded as Figure 1 the first rotation axis L in, and both extend along the first direction Y). The other end of the worm 22 is in meshing connection with the worm wheel 23. The worm wheel 23 is detachably connected to the adapter 30 and is used to drive the adapter 30 to rotate.

[0046] Meanwhile, when the driving component 10 is disposed on the mounting base 40, the output shaft 12 of the driving component 10 is parallel to the surface of the mounting base 40. Further, when the mounting base 40 is disposed on the switch panel, the extending direction of the worm 22 is parallel to the switch panel. Through the meshing connection between the worm gear 23 and the worm 22, the steering of the rotating shaft power transmission is realized, and thus the axis of the worm gear 23 is perpendicular to the switch panel. At this time, by adjusting the setting position of the mounting base 40 on the switch panel, the adapter 30 connected to the worm gear 23 can be coaxially arranged with the rocker, that is, the connection with the rocker can be realized. Finally, both ends of the entire operating tooling 1 for the medium-voltage switchboard (i.e., the mounting base 40 and the adapter 30 connected to the rocker) can be in the same plane (i.e., the switch panel), and at the same time, the rotational transmission of the connecting rod can be realized.

[0047] It should be understood that in this embodiment, the axis of the worm gear 23 can be regarded as the second rotation axis M.

[0048] In some other alternative embodiments, the transmission component 20 can also be rotationally connected in different directions through a plurality of connecting rods and a plurality of couplings. At this time, the extending direction of the output shaft 12 of the driving component 10 can be not limited, and the extending direction of the transmission component 20 can also be not specifically limited, as long as the mounting base 40 and the adapter 30 connected to the rocker are both located in the same plane during use.

[0049] Furthermore, the transmission component 20 further includes a transfer rod 24. The transfer rod 24 extends along the second direction X and is used to connect the adapter 30 and the worm gear 23. The worm gear 23 is sleeved on the outer periphery of the transfer rod 24, and the two are coaxially arranged (the axes of both can be regarded as the second rotation axis M), and both are perpendicular to the extending direction of the worm 22. The transfer rod 24 rotates together with the worm gear 23 under the drive of the worm gear 23. One end of the transfer rod 24 protrudes from the side of the worm gear 23 away from the worm 22. The adapter 30 is generally arranged in a through tubular shape, one end of which is detachably sleeved on the protruding transfer rod 24, and the other end is used to be detachably sleeved on the rocker.

[0050] Specifically, in this embodiment, the through holes at both ends of the adapter 30 have different shapes, and they can be through holes with a rectangular cross-section, a hexagonal cross-section or other polygonal cross-sections. Through the polygonal structure, the synchronous rotation with the transfer rod 24 and the rocker during the rotation process is realized.

[0051] Correspondingly, the exposed end of the rocker and the protruding end of the transfer rod 24 need to be correspondingly set to a matching shape.

[0052] In some other alternative embodiments, the adapter 30 may not be provided with through holes penetrating both ends, and the above effects can also be achieved by respectively opening grooves at both ends.

[0053] By providing an adapter 30 with grooves or through holes, the operating tooling 1 for the medium-voltage switchboard can be adapted to different models of medium-voltage switchboards. During specific use, only the adapter 30 corresponding to the rocker of this model needs to be replaced, so as to improve the universality of the equipment.

[0054] In some other alternative embodiments, the adapter 30 can also be rod-shaped, and both ends are respectively connected to the rocker and the adapter rod 24 through connecting parts such as couplings and bolts.

[0055] In some embodiments, the transmission assembly 20 further includes a housing 21 to protect the transmission of the worm gear 23 and the worm 22 and prevent damage to the transmission caused by foreign objects intrusion.

[0056] Specifically, the housing 21 is connected to the driving body 11 of the driving assembly 10, so that the output shaft 12 of the driving assembly 10, the worm gear 23 and the worm 22 of the transmission assembly 20 are all located inside the housing 21. The housing 21 is also provided with an output port 211. The adapter rod 24 connected to the worm gear 23 passes through the output port 211, so that the adapter 30 passes through the housing 21 (inside the output port 211) or is located outside the housing 21, so as to be detachably connected to the rocker outside the housing 21.

[0057] In some embodiments, the transmission assembly 20 further includes at least one bearing 25, which is fixed inside the housing 21 and sleeved on the outer periphery of the worm 22 to support and fix the worm 22, and prevent damage to the connection between the worm 22 and the output shaft 12 due to lack of support force during the handling and movement of the operating tooling 1 for the medium-voltage switchboard.

[0058] Specifically, the number of the bearings 25 can be multiple, and the multiple bearings 25 are arranged at intervals in the extending direction of the worm 22. At least part of the outer side end of each bearing 25 is fixed to the inner surface of the housing 21.

[0059] In some embodiments, the operating tooling 1 for the medium-voltage switchboard further includes a counter 50, which is arranged beside the end of the transmission assembly 20 far from the driving assembly 10 and is used to calculate the number of rotations, so as to accurately control the number of rotations of the transmission assembly 20 driving the adapter 30 to rotate, accurately control the position of the switch being rocked in / rocked out, and facilitate timely controlling the switch of the driving assembly 10 and stopping the operation of the driving assembly 10 in time after the switch is rocked in / rocked out in place.

[0060] Specifically, the counter 50 is signal-connected to the driving assembly 10, and the driving assembly 10 can receive the recording signal of the counter 50 and automatically stop running in time according to the recording signal.

[0061] In this embodiment, the counter 50 is a grating counter, which is arranged inside the housing 21 and at the end of the housing 21 away from the driving component 10, and is correspondingly arranged opposite to the worm wheel 23 and / or the adapter rod 24 and / or the adapter joint 30.

[0062] It should be understood that the grating counter can achieve the above effects by using existing technologies.

[0063] In some other alternative embodiments, the counter 50 can also select other devices with counting functions such as counting gears and rotary encoders.

[0064] In some embodiments, the operating tooling 1 for the medium-voltage switchboard further includes a torque protector (not shown in the figure). It is connected to the driving component 10.

[0065] In this embodiment, the torque protector is a current protector, and the driving component 10 is a DC driving component. The current protector is electrically connected to the driving component 10. During use, when the current protector monitors that the output current of the driving component 10 exceeds the limit value, it can control the driving component 10 to automatically shut down and issue an alarm.

[0066] It should be understood that according to the torque formula of the DC driving component (M = K * I * E / Z), its torque is proportional to the current. Therefore, the maximum current value of the driving component 10 during the use of the operating tooling 1 for the medium-voltage switchboard can be obtained by calculation, and by monitoring the magnitude of the output current of the driving component 10 during the specific use process, it can be monitored whether the torque exceeds the limit value.

[0067] It should be understood that the current protector can achieve the above effects by using existing technologies.

[0068] In some other alternative embodiments, it can also select an existing torque protector to monitor and protect the torque of the output shaft 12 through sensors and the like.

[0069] In some embodiments, the mounting base 40 is a magnetic base, and the presence or absence of the magnetism of the mounting base 40 can be controlled by a switch. Furthermore, it can be fixed on the switch panel when there is magnetism and removed from the switch panel when there is no magnetism.

[0070] It should be understood that the magnetic base can achieve the above effects by selecting existing technologies.

[0071] In some other alternative embodiments, the mounting base 40 can be a permanently magnetic mounting plate, or can be achieved by setting a magnet on the mounting base 40 without magnetism.

[0072] In some embodiments, the driving component 10 can also select a driving component 10 with a speed-changing function.

[0073] Understandably, the above embodiments only represent the preferred embodiments of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, the above technical features can be freely combined, and several deformations and improvements can also be made, which all fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made to the scope of the claims of the present utility model shall fall within the scope covered by the claims of the present utility model.
