Description

The device relates to the energy sector, namely to power lines, and is intended for leveling anchored reinforced concrete and metal poles of overhead lines, in particular poles of the SV-110 type. For supports of this type, the pile foundation is drilled into the ground, the support itself and the support slope are attached to it with clamps, and the slope is attached at the top with clamps or traverses.

Known jack for alignment of electrical supports (patent RU No. 138511, IPC E04H 12/34, published 10/11/2013).

The disadvantage of this device is that the jack is not fixed to the ground and fastening to the support in the form of a chain is not applicable to triangular metal supports (ELSI supports), and also has a complex design due to the use of a system of blocks.

A device for straightening supports is known (patent RU No. 111567, IPC E04H 12/34, published on 08/09/2011), which includes a jack with fixed blocks installed at the ends and an emphasis on its rear end.

The disadvantages of the device are the complex design and the lack of reliable fixation of the jack to the ground and support.

A support centering device is known, comprising a base, an inclined plate hinged to the base, a device for adjusting the angle between the base and the inclined plate, a jack mounted on the inclined plate, a support rod connected to the piston rod of the jack, and a clamp connected to the upper end of the support. The angle adjustment device contains a pin, while the lower end of the pin is fixedly connected to the base, the upper end of the pin passes through the inclined plate, the adjusting nut is screwed onto the pin (CN patent No. .

However, the known design is not convenient enough and unsafe in operation.

The task to be solved by the claimed utility model is to create a device that ensures the accuracy and simplicity of aligning the supports along the axes, the safety of work, and reducing the cost of special equipment.

This problem is solved by the fact that in a device for leveling anchor supports with a slope, containing a support platform and a plate pivotally attached to it, on which a jack is placed, the plate has the ability to change the angle of inclination relative to the support platform using control elements made in the form of replaceable wedges , the jack is equipped with a knot for fixing it on the sole of the cut, a stop for fixing the jack is rigidly fixed on the plate. The support platform is made with holes for installing pins in it to secure the platform from moving on the ground.

EFFECT: technical result consists in ensuring reliable fastening of the jack from movement when performing work on leveling anchor supports with slopes.

The essence of the utility model is illustrated by the drawings, where in Fig. 1 shows a diagram of the application of the device, Fig. 2 is a sketch of the device, in Fig. 3 - jack fixation unit on the slope of the reinforced concrete support.

The device is a support platform 1, made, for example, of wood, and a metal plate 3 attached to it by hinges 2. A stop 4 is made on the plate 3 for fixing the jack 5. The stop 4 has sides 6, made, for example, from a metal corner welded to the plate 3. The plate 3, due to the hinges 2, has the ability to change the angle of inclination relative to the support platform 1 using replaceable wooden wedges 7. The wedges 7 contribute to safe operation, since they have a large area of contact with the plate 3 and the support platform 1. The wedges 7 are made replaceable with different inclination angles, for example 15° or 30°. The defined angle of inclination eliminates the need for adjustments during operation. When installing the jack, a fixation unit 9 is installed between the sole of the cut 8 and the jack. To prevent sliding on the ground of the support platform 1, holes 10 are made in it, into which two steel pins 11 are inserted.

Work on the alignment of supports using the proposed device produced as follows.

The support platform 1 of the device is installed and fixed on the ground with the help of pins 11. A jack 5 is installed on the plate 3 at the stop 4. On top of the jack 5, a fixation unit 9 of the jack is installed on the slope 8 of the support 12. After setting the plate 3 to the required angle, a wedge 7 is placed with a certain angle of inclination, install the jack 5 to the cut 8. With the sides 13, the assembly 9 is fixed on the sole of the cut 8, and the upper part of the jack 5 is inserted into the groove 14 made in the fixation unit 9. Next, the clamps 15 of the cut 8 are loosened, the adjustment is made with the jack 5 the required vertical angle of the support 12. The completion of the work is carried out in the reverse order.

As a result of the application of the proposed device, the alignment of the supports occurs smoothly, accurately and safely, without displacement of the jack. The cost of manufacturing and using the device is much less than the cost of leveling the supports using special automotive equipment.
