Description

A portable and simple spanning frame for distribution network

technical field

The invention relates to a portable and simple spanning frame for distribution network.

Background technique

The wire-passing ring of the spanning frame is installed on the lifting pole, so that the wire can pass through the obstacle to be crossed effectively and safely, but the current wire-passing ring of the spanning frame has the following schemes: (1) The wire-passing ring is set as U-shaped The wire-passing ring, but the U-shaped wire-passing ring is easy to leave the ring due to the swing force of the wire during the wire pulling process; (2) The wire-passing ring is set as a circular wire-passing ring, and the circular wire-passing ring is Among them, although the wire can be locked in the wire-passing ring, the wire cannot be effectively lifted into the air, which has certain defects.

The present invention adopts the following technical solutions: a portable and simple spanning frame for distribution network, which is provided with pincer-shaped wire-passing rings, lifting rods and sites in sequence from top to bottom, and the upper end of the lifting rod is connected with the clamp-shaped wire-passing rings , the bottom end of the lift is connected to the ground, and the two clamp arms provided with the clamp-shaped wire passing ring are rotationally connected. A slide tube and a spring are horizontally provided between the two clamp arms of the clamp-shaped wire-passing ring, and the slide tube is located on the upper part. , one end of the sliding tube is connected to one of the tong arms for rotation, the other end of the sliding tube is inserted into the socket of the other tong arm, the spring is located at the bottom, there is a gap between the sliding tube and the spring, and the bottom of the two tong arms There is an opening pull wire between them, the opening pull wire is connected with the bottom of the two pliers arms in turn, and then connected with the lifting rod, pull the opening pull wire to open the two pliers arms, and the other end of the slide tube is separated from the jack of the pliers arm to let the wire leave the pliers. The wire ring is lifted into the air, and the opening pull wire is released to make the two pliers arms close naturally through the contraction of the spring. Two left pull ropes and two right pull ropes are symmetrically arranged on both sides of the lifting rod, and one end of the two left pull ropes is connected to the The top of the lifting rod is connected, the other end of the two left stay ropes is connected with the ground anchor on the ground, one end of the two right stay ropes is connected with the top of the lifting rod, and the other end of the two right stay ropes is connected with the ground anchor on the ground.

The lower part of the lifting rod is provided with a tripod. The lifting rod is a cylindrical epoxy resin rod. Each section of the casing of the lifting rod is provided with a spring wedge. When the casing is lifted to the position, the spring wedge spring positions the casing, and when the spring wedge is pressed, the lifting rod shrinks and extends. The opening stay wires are sequentially connected to the bottoms of the two pliers arms and then connected to the lifting rod to form four-direction stay wires.

The present invention has the following beneficial effects: after adopting the above technical scheme, the present invention can reduce power outage time, improve work efficiency and save engineering cost. The invention is provided with pincer-shaped wire passing rings, which not only reduce the frictional force, but also enable the wires of the new frame to pass through the crossing frame safely and quickly, and prevent the wires of the new frame from being damaged by friction when passing the wires and crossing the lines or obstacles. efficiency while improving reliability of power supply. The lifting rod of the present invention is a cylindrical epoxy resin rod, which not only improves the mechanical properties of the lifting rod, but also has excellent electrical insulation, and is light in weight and easy to carry. Load and wire passing capacity, good stability. The invention has a small volume and solves the problems of transportation and land occupation and high compensation for young crops. The jaws of the wire of the present invention are closed when the wire passes through the clamp-shaped ring, preventing the wire from bouncing off the ring. When the wire is tightened, the wire can be pulled through the opening to effectively separate the wire ring, so that the wire leaves the wire ring and lifts off, and the wire is released There is spring contraction and natural closure when passing the thread. The present invention is provided with a slide tube in the pincer-shaped wire passing ring, which can reduce the frictional force and enable the wire of the new frame to pass through the spanning frame safely and quickly. In the present invention, a spring wedge is separately installed inside each section of the casing, the casing is lifted to a fixed position, the spring wedge pops up, and the spring wedge is pressed into the casing to fall, and it can be adjusted up and down according to the site requirements. The opening guy wires described in the present invention are connected with the bottoms of the two pliers arms in turn and then connected with the lifting rods to form four-direction guy wires, which can be fixed by the guy wires, and a tripod is provided at the bottom of the lifting rods to keep it stable sex.
