[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] The effect achieved by the entire embodiment 1 is that the first travel switch 7 is electrically connected to the motor 9, and the second travel switch 15 is electrically connected to the electric push rod 2. When it is necessary to oil the intersection of the cross arm, the active arm of the cross arm is placed inside the positioning fixture 5, and then the active arm is locked by the positioning pin on the positioning fixture 5, and then the driven arm of the cross arm is placed inside the limit fixture 8. When the cross arm is installed, the motor 9 is started to drive the limit fixture 8 to rotate. When the limit fixture 8 is rotating, the mounting block 6 and the first travel switch 7 are used to match the first travel switch 7. When used together, the operating range of the limit fixture 8 can be limited, so that the driven arm on the limit fixture 8 can rotate. During the rotation of the driven arm, the valve on the oil filling pipe 402 can be opened, and then the vacuum pump 403 can be started to discharge the oil inside the oil tank 401 through the oil filling pipe 402 and drop it on the rotation center of the cross arm. Therefore, by filling oil during the rotation of the driven arm, the rotation center of the cross arm is evenly coated with oil. This is simple and efficient. The operator only needs to put the cross arm into the fixture to do the next sequence of work, which greatly improves the oiling efficiency.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, a sliding groove 10 is provided on the outer surface of one side of the support frame 1, and a sliding block 13 is movably connected to the inner surface of the sliding groove 10, a threaded rod 14 is fixedly connected to the right surface of the sliding block 13, and a nut 12 is threadedly connected to the outer surface of the threaded rod 14, and the left surface of the sliding block 13 is fixedly connected to the connecting block 11, and the left surface of the connecting block 11 is fixedly connected to the second travel switch 15, and the position of the second travel switch 15 matches the position of the oil tank 401.

[0026] The effect achieved by the entire embodiment 2 is that, during the process of oiling the cross arm, the nut 12 can be loosened to allow the sliding block 13 to slide in the sliding groove 10, thereby adjusting the position of the connecting block 11 on the support frame 1 and adjusting the position of the second travel switch 15. After the adjustment is completed, the nut 12 is screwed into the threaded rod 14 and tightened to complete the fixation of the sliding block 13. When filling oil, the electric push rod 2 is started to drive the oil tank 401 to move downward. When it moves to the specified position, the oil tank 401 will contact the second travel switch 15, causing the electric push rod 2 to stop, and the stop position of the oil filling pipe 402 is accurately defined to avoid the height of the oil filling pipe 402 being too high or too low.

[0027] Working principle: when it is necessary to oil the intersection of the cross arm, place the active arm of the cross arm inside the positioning fixture 5, and then lock the active arm through the positioning pin on the positioning fixture 5, and then place the driven arm of the cross arm inside the limit fixture 8. When the cross arm is installed, the nut 12 can be loosened to allow the sliding block 13 to slide in the sliding groove 10, thereby adjusting the position of the connecting block 11 on the support frame 1, and adjusting the position of the second travel switch 15. After the adjustment is completed, screw the nut 12 into the threaded rod 14 and tighten it to complete the fixation of the sliding block 13, start the electric push rod 2, and drive the oil tank 401 to move downward. When it moves to the specified position, the oil tank 401 will contact the second travel switch 15, causing the electric push rod 2 to stop. , accurately define the stop position of the oil filling pipe 402, and then start the motor 9 to drive the limit fixture 8 to rotate. When the limit fixture 8 is rotating, the installation block 6 and the first stroke switch 7 are used in conjunction to limit the operating range of the limit fixture 8, so that the driven arm on the limit fixture 8 can rotate. During the rotation of the driven arm, the valve on the oil filling pipe 402 can be opened, and then the vacuum pump 403 can be started to discharge the oil inside the oil tank 401 through the oil filling pipe 402 and drop it on the rotation center of the cross arm, so that the rotation center of the cross arm is evenly coated with oil by oiling during the rotation of the driven arm. It is simple and efficient. The operator only needs to put the cross arm into the fixture to do the next sequence of work, which greatly improves the oiling efficiency.
