Abstract
Description
Technical Field
[0001] This utility model belongs to the field of circuit construction technology, and in particular relates to an auxiliary device for the construction of high-voltage transmission and transformation lines. Background Technology
[0002] An insulated operating rod is a general term for a set of insulated tools specifically designed for use in power systems. It can be used for live-line work, live-line inspection, and live-line maintenance.
[0003] Because conventional insulating rods are extended by splicing, they need to be disassembled when they need to be retracted, making the retraction and unfolding process quite troublesome.
[0004] To address this issue, we propose an auxiliary device for the erection of high-voltage transmission and transformation lines. Utility Model Content
[0005] The purpose of this utility model is to solve the problem of the cumbersome operation of conventional insulating rod retraction and extension, and to propose an auxiliary device for the erection of high-voltage transmission and transformation lines.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A high-voltage transmission line erection auxiliary device includes a main pole, a daughter pole slidably mounted inside the main pole, a first sealing sleeve between the main pole and the daughter pole, the first sealing sleeve being sealed outside the daughter pole and threadedly sealed onto the main pole, an insulator fixedly fitted outside the main pole, a cover threadedly sealed at the tail of the main pole, and the root of the daughter pole threadedly matched with the inner wall of the head of the main pole, and the root of the daughter pole slidingly matched with the inner wall of the main pole. The daughter pole is pulled outwards, then screwed so that the root of the daughter pole is spirally attached to the head of the main pole. Then, the main pole is held by hand to operate the daughter pole to operate the target wire. The first sealing sleeve seals between the main pole and the daughter pole, preventing water from entering the main pole. The daughter pole is then screwed inwards and retracted into the main pole, facilitating the deployment and retraction of the main pole and the daughter pole.
[0008] Preferably, the mother rod includes a rod body, and a first insulating sleeve is fixedly connected to the rod body. The rod body guides the sliding of the sub-rod, and the first insulating sleeve blocks the outside of the rod body to prevent the rod body from conducting electricity, thus facilitating the guidance of the sub-rod's sliding.
[0009] Preferably, the main rod further includes a retaining ring, which is fixedly connected to one end of the first insulating sleeve. When the sub-rod is pulled out, the retaining ring is used to stop at the base of the sub-rod to prevent it from being completely pulled out, thereby improving the stability of pulling the main rod and the sub-rod.
[0010] Preferably, the sub-rod includes a second insulating sleeve, an inner rod, and a bolt. The second insulating sleeve is fixedly connected to the outside of the inner rod, and the bolt is fixedly connected to the tail of the second insulating sleeve. The inner rod blocks the outside of the bolt, and the bolt is threaded to the inner wall of the head of the first insulating sleeve. The second insulating sleeve and the bolt are slidably inserted inside the first insulating sleeve. When the sub-rod is pulled outwards, the bolt is screwed onto the head of the first insulating sleeve. A retaining ring blocks the outside of the bolt to prevent it from being unscrewed, thus improving the stability of the sub-rod in its deployed state.
[0011] Preferably, the first sealing sleeve includes a knob and a second sealing sleeve, the second sealing sleeve being sealed outside the second insulating sleeve, and the knob being threaded onto the outside of the retaining ring; the second sealing sleeve seals the outside of the retaining ring. By using the second sealing sleeve to seal outside the second insulating sleeve, water is prevented from flowing into the first insulating sleeve along the second insulating sleeve, thus improving the safety factor.
[0012] Preferably, the second sealing sleeve includes a sealing ring and a sealing sleeve body, which are fixedly connected as a single unit. The sealing sleeve body is inserted into the knob, the sealing ring blocks the opening of the knob, the sealing sleeve body is sealed onto the second insulating sleeve, and the sealing ring seals between the knob and the retaining ring. The sealing sleeve body and sealing ring isolate the gap between the second insulating sleeve and the retaining ring, facilitating waterproofing.
[0013] In summary, the technical effects and advantages of this utility model are as follows:
[0014] 1. Pull the sub-rod outwards, then twist the sub-rod so that the base of the sub-rod is screwed onto the head of the main rod. Then, hold the main rod and operate the sub-rod to operate the target wire. Use the first sealing sleeve to seal between the main rod and the sub-rod to prevent water from entering the main rod. Twist the sub-rod in one direction and then retract the sub-rod into the main rod to facilitate the extension and retraction of the main rod and the sub-rod.
[0015] 2. The rod body guides the sliding of the sub-rod, and the first insulating sleeve is used to block the outside of the rod body to prevent the rod body from conducting electricity and facilitate the sliding of the sub-rod;
[0016] 3. When pulling out the sub-rod, use the retaining ring to stop at the base of the sub-rod to prevent it from being completely pulled out, thus improving the stability of pulling out the main rod and the sub-rod.
[0017] 4. Pull the sub-rod outwards, then screw the bolt onto the head of the first insulating sleeve. Use the retaining ring to block the outside of the bolt to prevent it from being unscrewed, thus improving the stability of the sub-rod in its unfolded state.
[0018] 5. The second sealing sleeve is used to seal the outside of the second insulating sleeve, preventing water from flowing into the first insulating sleeve along the second insulating sleeve, thus improving the safety factor. Attached Figure Description
