DETAILED DESCRIPTION
[0028] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments only are a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.
[0029] REFERENCE Figures 1-4The utility model provides an electrical performance test tool for rail transit, which comprises a test bottom plate 1, a test top plate 2 and a test unit 9. The test top plate 2 is connected to a lifting unit for driving it to move up and down. It is to be noted that four guide rods are inserted into the four corners of the test bottom plate 1, and the guide rods penetrate through the test top plate 2 and are in sliding connection with the guide sleeves on the upper side of the test top plate 2.
[0030] The test top plate 2 is located on the upper side of the test bottom plate 1. The test work on the conductive ring of the motor rotor needs to be carried out between the test bottom plate 1 and the test top plate 2. In order to facilitate observation and allow light to enter better, trapezoidal holes are arranged in the test top plate 2 and the test bottom plate 1.
[0031] In a further embodiment, a position adjusting unit 4 is installed on the test bottom plate 1. The position adjusting unit 4 is used to drive the test bench 3 to move forward and backward. Specifically, two groups of main tracks are arranged in the position adjusting unit 4, and the two groups of main tracks are symmetrically distributed about the center line of the test bottom plate 1. In order to avoid the test bench 3 in the middle from collapsing, an auxiliary sliding block 5 is installed directly below the test bench 3. The auxiliary sliding block 5 cooperates with an auxiliary track 6, and the auxiliary track 6 is parallel to the main tracks in the position adjusting unit 4. Multiple positions inside the rail transit need to be provided with motors, such as brakes, air supply and the like. When the motors are overhauled and tested, the main components, i.e. the rotors, need to be detected.
[0032] Specifically, the test bench 3 is provided with a mounting seat 7 for storing the motor rotor. The mounting seat 7 is provided with a key groove 701. The key groove 701 is connected to the motor rotor through a flat key. The mounting seat 7 is connected to a direction adjusting assembly 8 for driving it to rotate.
[0033] More specifically, the direction adjusting assembly 8 comprises a first gear 801. The first gear 801 is sleeved on a rotating shaft. The rotating shaft is connected to the base through a bearing. The mounting seat 7 is arranged on the upper side of the rotating shaft. The first gear 801 is connected to a second gear 802 through tooth engagement transmission. The second gear 802 is connected to the output shaft of a driving motor. The driving motor can drive the second gear 802 connected thereto to rotate. The second gear 802 drives the first gear 801, the rotating shaft and the mounting seat 7 to rotate through tooth engagement. The key groove 701 in the mounting seat 7 is connected to the rotor of the motor through a flat key. The mounting seat 7 can drive the motor rotor inside it to rotate together during the rotation of the mounting seat 7.
[0034] When the voltage test on the conductive ring of the motor rotor is carried out, the two conductive units 12 connected to the test unit 9 need to be connected to the two conductive rings respectively. Therefore, two adjusting sleeves 10 are arranged on the lower side of the test top plate 2. The first support rod 11 and the second support rod are installed on the upper side of the adjusting sleeve 10. The conductive unit 12 is installed on the side of the first support rod 11 away from the adjusting sleeve 10.
[0035] When testing the voltage between the two conductive rings, the dust adhered to the conductive ring needs to be removed to avoid affecting the test results of the voltage, therefore, the cleaning block 13 is installed on the second supporting rod connected with the adjusting sleeve 10, and the cleaning cloth 14 is wrapped outside the cleaning block 13, and it should be noted that the blocking block 15 is installed on the cleaning block 13, and the blocking surface is arranged on the side away from the adjusting sleeve 10, and the blocking surface is arranged in an arc shape.
[0036] Before the conductive unit 12 is connected with the conductive ring on the motor rotor, the dust adhered to the outer surface of the conductive ring needs to be removed, and in the specific operation, the cleaning block 13 and the cleaning cloth 14 are close to the conductive ring, and the motor rotor is driven to rotate by the direction adjusting assembly 8, so that the side point connected with the conductive unit 12 is wiped clean, and dust is avoided to exist at the connection position of the conductive unit 12 and the conductive ring.
[0037] It should be noted that the vibration motor 16 is arranged between the second supporting rod and the cleaning block 13, and the vibration motor 16 can drive the cleaning block 13 to reciprocate up and down, and in the process of reciprocating, the dust adhered to the cleaning block 13 and the cleaning cloth 14 is removed by inertia.
[0038] In order to adapt to the voltage test of the conductive ring inside the motor rotor with different sizes, the spacing adjusting unit 17 is installed on the two adjusting sleeves 10, and the spacing adjusting unit 17 is used for adjusting the spacing between the two adjusting sleeves 10, and specifically, one adjusting sleeve 10 is fixedly installed on the longitudinal track, and the other adjusting sleeve 10 is slidably connected with the longitudinal track through the longitudinal sliding block, the longitudinal sliding block is connected with the lead screw through threads, and the lead screw is connected with the power motor for driving the lead screw to rotate forward and backward.
[0039] In order to enable the conductive unit 12 to contact the conductive ring, the spacing adjusting unit 17 is installed on the transverse position adjusting assembly, the transverse position adjusting assembly can adjust the position of the spacing adjusting sleeve 10 in the left-right direction, and the direction in which the transverse position adjusting assembly travels is perpendicular to the direction in which the position adjusting unit 4 travels.
[0040] Working principle:
[0041] Before the conductive unit 12 is connected with the conductive ring on the motor rotor, the dust adhered to the outer surface of the conductive ring needs to be removed, and in the specific operation, the cleaning block 13 and the cleaning cloth 14 are close to the conductive ring, and the motor rotor is driven to rotate by the direction adjusting assembly 8, so that the side point connected with the conductive unit 12 is wiped clean, and dust is avoided to exist at the connection position of the conductive unit 12 and the conductive ring.
[0042] After the cleaning of the conductive rings, the two conductive units 12 in the two adjusting sleeves 10 are connected with the two conductive rings of the motor rotor respectively, the test unit 9 is turned on, and the voltage between the two conductive rings in the motor rotor is measured.
[0043] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
