Description

Technical Field

[0001] The utility model belongs to the technical field of slip ring detection equipment, and particularly relates to a slip ring axial movement detection device. Background Art

[0002] A slip ring is a device used to transmit electrical signals and power between relatively rotating components. It ensures continuous and stable transmission of current and signals throughout a device's 360° rotation, preventing wire entanglement during rotation.

[0003] The slip ring mainly consists of a stator and a rotor. During the installation process, it is necessary to control the coaxiality of the rotor and the stator, such as using precise positioning fixtures and measuring tools, to ensure that the slip ring is installed well. After the installation is completed, in order to detect the assembly effect, the axial movement of the slip ring needs to be tested.

[0004] Currently, the detection of axial movement of the slip ring requires fixing the slip ring stator, applying a certain pulling force to the slip ring rotor, and then using a displacement measuring instrument to determine whether the rotor displacement meets the requirements. However, this detection method requires the cooperation of multiple people and the ability to control the force stably, making it relatively complicated and laborious to operate. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a slip ring axial movement detection device for solving the problem of complicated slip ring detection operation.

[0007] worktop;

[0008] A rotating support mechanism is provided on the operating table, the stator of the slip ring is mounted on the rotating support mechanism, and the rotating support mechanism is used to drive the stator of the slip ring to rotate;

[0009] a counterweight unit, a top end of which is connected to the rotor of the slip ring;

[0010] A displacement sensor is installed on the top of the counterweight unit or the bottom of the rotor of the slip ring, with the transmitting end of the displacement sensor facing the operating table at the bottom.

[0011] Compared with the existing technology, the above technical solution has the following beneficial effects:

[0012] The stator of the slip ring is connected to the rotating support mechanism. The rotating support mechanism can drive the stator of the slip ring to rotate. At the same time, the counterweight unit is connected to the rotor of the slip ring, which can apply a stable pulling force to the rotor. By reading and calculating the change in the reading of the displacement sensor before and after connecting the counterweight unit, it is determined whether it is within the required range. The overall operation is relatively simple. The slip ring is directly fixed on the rotating support mechanism and the counterweight unit is connected.

[0017] The driving mechanism has an output end engaged with the outer ring of the slewing bearing to drive the outer ring of the slewing bearing to rotate.

[0018] The outer ring of the slewing bearing is driven by a driving mechanism to rotate, which can drive the stator and rotor of the slip ring to rotate relative to each other. When the rotor and stator of the slip ring are at different rotation angles, axial movement detection can be performed in real time.

[0041] like Figure 1 As shown, the present invention provides a device for detecting axial movement of a slip ring, which includes: an operating table 1, a rotation support mechanism 2, a counterweight unit 3 and a displacement sensor 4.

[0042] The rotating support mechanism 2 is arranged on the operating table 1, and the stator of the slip ring is installed on the rotating support mechanism 2. The slip ring is not shown in the figure. The rotating support mechanism 2 is used to drive the stator of the slip ring to rotate. The top of the counterweight unit 3 is connected to the rotor of the slip ring. The displacement sensor 4 is installed on the top of the counterweight unit 3 or the bottom of the rotor of the slip ring. The transmitting end of the displacement sensor 4 faces the bottom of the operating table 1. The displacement sensor 4 can be a laser displacement sensor 4. When the counterweight unit 3 drives the slip ring rotor to displace, the displacement sensor 4 can detect the displacement in real time. The displacement sensor 4 transmits the displacement signal to an external device for reading and display.

[0043] The stator of the slip ring is connected to the rotating support mechanism 2. The rotating support mechanism 2 can drive the stator of the slip ring to rotate. At the same time, the counterweight unit 3 is connected to the rotor of the slip ring, which can apply a stable pulling force to the rotor. By reading and calculating the change in the reading of the displacement sensor 4 before and after connecting to the counterweight unit 3, it is determined whether it is within the required range. The overall operation is relatively simple. The slip ring can be directly fixed on the rotating support mechanism 2 and the counterweight unit 3 can be connected.

[0044] Specifically, the rotating support mechanism 2 includes a support frame 201 and a driving mechanism 203. The support frame 201 is fixed on the operating table 1. The inner ring of the slewing bearing 202 is installed on the top of the support frame 201. The top of the outer ring of the slewing bearing 202 is provided with a mounting hole 204 for connecting with the stator of the slip ring. The stator of the slip ring is connected and fixed to the outer ring of the slewing bearing 202. The output end of the driving mechanism 203 fixed on the operating table 1 is engaged with the outer ring of the slewing bearing 202 to drive the outer ring of the slewing bearing 202 to rotate. Since the slip ring stator is fixed on the outer ring of the slewing bearing 202, the driving mechanism 203 can drive the slip ring stator to rotate.

[0045] The driving mechanism 203 drives the outer ring of the slewing bearing 202 to rotate, and the stator and the rotor of the collector ring are relatively rotated, and the axial displacement detection can be performed in real time when the rotor and the stator of the collector ring are at different rotation angles.

[0046] In the embodiment, the counterweight unit 3 comprises a connecting disc 301, a connecting rod 302 and a tray 303 connected in sequence.

[0047] The connecting disc 301 is connected to the rotor of the collector ring, and the connecting disc 301 is connected to the rotor of the collector ring at the center of the slewing bearing 202. Specifically, the connecting disc 301 is fixed to the rotor of the collector ring by bolts or the like.

[0048] The top end of the connecting rod 302 is connected to the connecting disc 301, the connecting rod 302 passes through the operation table 1, the tray 303 is connected to the bottom end of the connecting rod 302 passing through the operation table 1, and the tray 303 is used for placing counterweight blocks. The tray 303 is located below the operation table 1 through the connecting rod 302, and the counterweight blocks are placed.

[0049] The connecting disc 301 and the rotor of the collector ring can be stably connected, the bottom end of the connecting rod 302 passes through the operation table 1 and is connected to the tray 303, and different counterweight blocks are placed on the tray 303 for better operation, thereby exerting different pulling forces.

[0050] In order to ensure the stability of the connecting rod 302, a bearing seat 5 is sleeved outside the connecting rod 302, and the bearing seat 5 is installed on the operation table 1. The bearing seat 5 can ensure that the connecting rod 302 does not shake during rotation, and can ensure the stability of the connecting disc 301 above and the tray 303 below. The bearing seat 5 arranged on the operation table 1 can limit the shaking and deflection of the connecting rod 302.

[0051] In addition, the connecting rod 302 is provided with a scale line, and the connecting rod 302 can be seen from the scale line. The distance of the connecting rod 302 downward displacement can be seen from the scale line in cooperation with the bearing seat 5, and the situation of the axial displacement of the collector ring can be further judged.

[0052] The top end of the connecting rod 302 is detachably connected to the connecting disc 301, so that the connecting rod 302 can be easily separated from the bearing seat 5.

[0053] In order to ensure the smooth rotation of the slewing bearing 202, the connecting rod 302 is connected to the bottom center of the connecting disc 301, and the connecting rod 302 is coaxially arranged with the slewing bearing 202, so that when the slewing bearing 202 rotates, the rotor of the collector ring does not interfere with the rotation of the counterweight unit 3 below.

[0054] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
