Description

A Bubble Balance Double Scale Pole Corrector

technical field

The utility model relates to the field of electric power engineering construction, in particular to a bubble balance double-scale electric pole straightening device.

Background technique

During the construction of electric power projects, the erection of electric poles is an important task. The verticality of electric poles directly determines its strength to withstand bad weather and man-made damage, especially when electric poles are erected in places with uneven mountains or soft soil. The tilt of the pole, strong wind, ice and snow, or accidental external force may increase the tilt of the pole and even cause the pole to collapse, interrupting the power supply and reducing the reliability of the power supply. Once the pole collapses, the power recovery time will be longer.

When the pole is erected, the alignment of the pole is mostly realized by visual observation or plumb bob. When observed with the naked eye, the error is relatively large due to the influence of personal subjective judgment and terrain. Using the plumb bob to measure the alignment, the plumb bob line is kept parallel to the electric pole. The judgment of this parallelism is also judged subjectively by the naked eye. In addition to the influence of the taper of the electric pole, the position of the plumb bob and the wind force on site, there are large errors.

Pole alignment by naked eye observation or plumb weight can only subjectively and qualitatively determine whether the pole is vertical, and cannot quantitatively measure and align the pole.

Simple-to-operate bubble-balanced double-scale pole corrector.

In order to achieve the above-mentioned purpose, the utility model comprises a bracket arranged horizontally, a slide rail extending horizontally along the longitudinal direction of the bracket is provided on the bracket, and a splint that can only slide along the slide rail and vertically cooperate with the bracket is installed on the slide rail through a sliding device. The sleeve sliding device is elastically connected to the horizontal center of the bracket through a spring respectively, and the ends of the two splints are connected together through an elastic connection device. The bracket is symmetrically provided with a line scale extending from the horizontal center of the bracket to both ends, and the bracket is fixed with a shaft. To the transparent balance tube set parallel to the bracket, the balance tube is filled with balance liquid, and there is a balance bubble in the balance liquid.

Corresponding to the zero-degree line extending up and down along the outer wall of the balance tube, the outer wall of the balance tube is also provided with an angular scale centered on the lower end of the zero-degree line and extending outward evenly.

As an improvement, an arc groove matched with the side wall of the pole is provided on the side wall of the splint close to the pole.

As an implementation, the sliding device includes an inner plate and an outer plate that are symmetrically arranged on both sides of the bracket to slide and cooperate with the side wall of the bracket, and a sliding joint is fixed between the half of the inner plate and the half of the outer plate near the transverse center of the bracket.

The bracket is used to support the whole set of devices. Its horizontal position determines the vertical position of the pole, and the line scale is engraved on it.

The handle is tightly fixed with the bracket, and the operator holds the force-applying part.

The slide rail is used for the free movement of the splints on both sides and can adapt to the taper change of the electric pole.

The interface between the balance bubble and the balance liquid is used as the positive measurement boundary of the pole.

When the pole is vertical, the 0 scale line and the vertical center line of the bubble are in the same plane. The tilt angle of the pole can be calculated quantitatively by using the scale difference of the boundary angle on both sides of the bubble.

The springs are located in the slide rails and distributed symmetrically with the 0 scale line as the symmetrical axis, and the elastic coefficients and lengths of the springs on both sides are equal to ensure that the two splints move the same distance to both sides.

Rubber band: One end is fixed in the groove of one splint, and after the splint is placed, the other end is hung in the groove of the other splint to finally fix the device.

It can be seen from the above-mentioned technical scheme that the utility model provides a bubble balance double-scale electric pole straightening device, which can reflect the inclination of the electric pole through the offset of the balance bubble, and use the angle scale to quantitatively measure the electric pole, so as to improve the electric pole Precision during erection construction.
