Description

Isometric rod erector and method of use thereof

technical field

The invention belongs to the technical field of pole devices, and in particular relates to an equal-diameter pole pole device and a use method thereof.

Background technique

The equal diameter rod is the support of all the structures in the substation, so the assembly of the equal diameter rod is a very important task. A 300-400 cm square plate is welded on the top of the equal-diameter pole. Before the vertical pole was hoisted, the steel wire rope was used to tie the equal-diameter pole near the top of the pole, that is, under the square plate. When hoisting, due to the uneven force on the equal-diameter pole, there will be a certain angle with the ground, and it will often spiral when falling, and it is difficult to enter the pole pit vertically. It takes 3 to 4 people to straighten it to enter the pole pit. At the same time, there is a certain Hidden danger.

Its additional technical features are: the U-shaped hoop is semicircular;

The cross section of the U-shaped hoop is rectangular;

The reinforcing plate is arranged vertically, the top of the reinforcing plate is flat or toothed, and the top of the reinforcing plate extends into the U-shaped hoop;

The radius of the lifting eye is 23-25 cm;

The radius of the lifting eye is 24 cm.

The second technical problem to be solved by the present invention is to provide a method for using the equal-diameter rod erector.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention comprises the following steps:

The first step is to weld the square plate

Weld the square plate at the top of the equal-diameter rod firmly;

The second step is to install the hoop

Fix the two U-shaped hoops on the equal-diameter rod under the square plate with nuts and bolts;

The third step hoisting

Pass the steel wire rope of the hoist through the hoisting eye, hoist the equal-diameter rod, and the equal-diameter rod is vertical to the ground after being hoisted. One person corrects the position of the equal-diameter rod, enters the rod pit, and fixes the equal-diameter rod;

The fourth step is to remove the hoop

Loosen the nuts and bolts that fix the two U-shaped hoops, place the two U-shaped hoops on the ground with the wire rope of the hoisting machine, pull the wire ropes away from the hoisting eye, and put the two U-shaped hoops back into storage.

When the equal-diameter rod erector provided by the present invention is used, the square plate on the top of the equal-diameter rod is first welded firmly, and then two U-shaped hoops are fixed on the equal-diameter rod below the square plate with nuts and bolts, and then Pass the steel wire rope of the hoist through the hoisting eye, and the hoist lifts the equal-diameter rod. Because the two U-shaped hoops are arranged symmetrically, the equal-diameter rod is vertical to the ground after being hoisted. Only one person needs to correct the position of the equal-diameter rod, and the equal-diameter rod will easily enter the rod pit, and then fix the equal-diameter rod. After hoisting, loosen the nuts and bolts that fix the two U-shaped hoops, place the two U-shaped hoops on the ground with the steel wire rope of the hoisting machine, pull the wire rope away from the hoisting eye, and put the two U-shaped hoops back into storage . The hoisting process saves manpower while ensuring the safety of construction. The U-shaped hoop is semicircular, easy to install and fix. The cross section of the U-shaped hoop is rectangular, which reduces weight while ensuring stability. The reinforcement plate is arranged longitudinally, the top of the reinforcement plate is flat or toothed, the top of the reinforcement plate extends into the U-shaped hoop, and the reinforcement plate and the U-shaped hoop are welded firmly. According to needs, the radius of the hoisting eye is 23-25 cm, and the radius of the hoisting eye is preferably 24 cm.

detailed description

The isometric rod erector provided by the present invention and its usage method will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the equal-diameter rod erector provided by the present invention includes two U-shaped hoops 1, the U-shaped hoops 1 are semicircular, and the tops of the two U-shaped hoops 1 pass through nuts 2, bolts 3 are connected, and the tail ends of the two U-shaped hoops 1 are respectively provided with reinforcement plates 4 .

As shown in Figure 2, the cross section of the U-shaped hoop 1 is rectangular, the tail end of the U-shaped hoop 1 is provided with a reinforcement plate 4, the tail end of the reinforcement plate 4 is provided with a hoisting eye 5, and the reinforcement plate 4 is arranged longitudinally to strengthen The top of the plate 4 is a plane, and the top of the reinforcing plate 4 extends into the U-shaped hoop 1 .
