Technical Field
[0001] The utility model relates to the technical field of suspension wire clamps, in particular to a suspension wire clamp which is convenient for monitoring the wear of a rotary shaft. Background Art
[0002] A suspension clamp is a hardware fixture that can be used to suspend a conductor to a suspension insulator string or a hardware string. There are many types of suspension clamps, including the old-fashioned boat-shaped clamp and the pre-twisted suspension clamp. Common suspension clamps generally include a hanger, a U-shaped screw, and a main body.
[0003] The suspension wire clamp includes a main body, a rotating shaft fixed on the main body, and a bracket rotatably connected to the rotating shaft; the bracket rotates on the rotating shaft under the action of wind, so the bracket and the rotating shaft are prone to wear; the commonly used method is to set a relay electrically connected to the central processing unit on the bracket, and the relay is connected to a coil, and the coil is set on the bracket. When the bracket is worn, the coil is also worn, so the relay becomes open circuit. At this time, the central processing unit detects the open circuit signal of the relay, and then transmits the open circuit signal to the alarm, which sounds an alarm.
[0004] However, according to the wear of the suspension clamps that have been eliminated due to wear, it can be seen that the wear degree of the rotating shaft is often much higher than that of the bracket. Therefore, this method cannot effectively monitor the wear condition of the rotating shaft. The rotating shaft may break or wear through due to wear, which may cause the wire to detach from the suspension clamp and cause the wire to ground. Utility Model Content
[0005] The purpose of the utility model is to provide a suspension wire clamp which is convenient for monitoring the wear of the rotating shaft. The utility model has the advantage of being able to more effectively monitor the wear of the rotating shaft and avoid the conductor from escaping from the suspension wire clamp, thereby preventing the conductor from grounding.
[0006] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions:
[0007] A suspension wire clamp for monitoring wear of a rotary shaft, comprising a main body, two rotary shafts, and a hanging bracket, wherein the two rotary shafts are fixed on both sides of the main body, and the two ends of the bottom of the hanging bracket are rotatably sleeved on the rotary shafts, and the two rotary shafts are respectively plugged with pins;
[0008] A detection component is provided on the rotating shaft, and the detection component includes a relay and a coil; two through-holes are provided at the end of the rotating shaft along the axial direction, and the relay is fixedly provided on the rotating shaft, one end of the coil is electrically connected to the input end of the relay, and the other end of the coil passes through one through-hole, and then passes through the other through-hole in the opposite direction and is electrically connected to the output end of the relay.
[0009] Through the above technical solution, the two ends of the coil are electrically connected to the input and output ends of the relay respectively, thereby forming a closed path; the relay is fixedly installed on the rotating shaft, and two through-holes are provided on the rotating shaft, and the coil is passed through the two through-holes; when the rotating shaft is worn to the point that the coil in the through-hole is worn off, the central processing unit detects the open-circuit signal of the relay and then transmits the open-circuit signal to the alarm; thereby realizing effective monitoring of the wear of the rotating shaft, avoiding the situation where the rotating shaft is broken or worn through due to force after wear, which in turn causes the wire to detach from the suspension clamp, resulting in an accident where the wire is grounded.
[0010] In one embodiment of the present invention, the pin is horizontally inserted into the rotary shaft.
[0011] In one embodiment of the present invention, the two through holes are vertically distributed on both sides of the pin.
[0012] In one embodiment of the present invention, a plurality of mounting plates are fixedly provided at the front end of the rotary shaft, and the relay is fixedly mounted on the mounting plates.
[0013] In one embodiment of the present invention, a pad is sleeved on the rotary shaft between the pin and the hanger.
[0014] In one embodiment of the present invention, a plurality of distance sensors are provided on the pad and are distributed equidistantly with the rotation axis as the center.
[0015] In one embodiment of the present invention, four distance sensors are provided on the pad.
[0016] In one embodiment of the present invention, the distance sensor is located in front of the pin shaft.
[0017] Through the above technical solution, four distance sensors are used to monitor the position of the rotating shaft. When the distance sensor on one side senses that the distance to the rotating shaft increases or decreases, the distance sensor on the opposite side senses that the distance to the rotating shaft decreases or increases, which indicates that the rotating shaft is worn; and the wear of the rotating shaft is then monitored.
[0018] As described above, the utility model of a suspension wire clamp for monitoring the wear of a rotary shaft has the following beneficial effects:
[0019] 1. The two ends of the coil are electrically connected to the input and output ends of the relay, respectively, forming a closed circuit. The relay is fixedly mounted on a rotating shaft, which has two through-holes through which the coil is inserted. When the rotating shaft wears to the point where the coil in the through-hole is worn off, the central processing unit detects the open-circuit signal from the relay and transmits the open-circuit signal to the alarm. This effectively monitors the wear of the rotating shaft and prevents the shaft from being broken or worn out due to stress caused by wear, which could cause the wire to detach from the suspension clamp and cause a wire grounding accident.
[0020] 2. Four distance sensors are used to monitor the position of the rotating shaft. When one distance sensor senses an increase or decrease in the distance to the rotating shaft, the other distance sensor senses a decrease or increase in the distance to the rotating shaft, indicating that the rotating shaft is worn. The wear of the rotating shaft is then monitored.
[0021] 3. The detection component and the distance sensor jointly monitor the wear of the rotary shaft. When one of them fails, the other can continue to monitor the wear of the rotary shaft. BRIEF DESCRIPTION OF THE DRAWINGS

In this embodiment, four mounting plates 9 are welded to the upper, lower, left and right sides of the front end of the rotating plate.
