Description

The utility model relates to the field of energy and can be used in the operation of overhead power lines (hereinafter - overhead lines).

There are a number of devices and mechanisms that are used to level the supports of overhead lines.

Known devices for straightening supports [1, 2], including a housing, a retractable rod, a fixing mechanism to the support and a winch.

The disadvantages of this device are:

- low structural reliability due to the presence of rotating elements;

- narrow area of application, due to the need to select a mount for a specific type of support;

- the risk of breaking the cable and subsequent lowering of the stem, due to the lack of a locking device;

- Lack of anti-slip teeth and carrying handles.

The task of the utility model is to expand the arsenal of technical means used to level the supports of overhead lines.

The technical result consists in the implementation of the specified purpose and the creation of an efficient and reliable in operation universal device for aligning the supports of overhead lines.

The problem is solved, and the technical result is achieved by creating and using a portable device consisting of a hydraulic cylinder with a built-in manual oil pump and a check valve and a drain nozzle installed in it, while an L-shaped support with anti-skid teeth is fixed in the lower part of the hydraulic cylinder, on the upper part its rod is threaded for connecting intermediate rods and (or) an extension rod with hard alloy stops, and handles for transportation are welded in its center of gravity.

A portable foot alignment device is shown in FIG. one.

A photograph of the claimed device is shown in FIG. 2.

The device consists of a bottle-type hydraulic cylinder (1) (for example, a hydraulic bottle jack Gigant 3T HBJ-3 or a hydraulic cylinder with a built-in pump art. 3.703 "Sorokin") with a built-in manual oil pump (2). In the lower part of the device there is an L-shaped support (3) with welded anti-skid teeth (5), which is fixed with two M 10 bolts (4) to the oil pump body (2). The upper part of the rod (6) of the hydraulic cylinder (1) has an M32 thread (7) for installing an extension rod (8). On one side of the extension rod (8), a fastening in the form of a U-shaped bracket (9) with hard alloy stops welded along the inner radius is welded, on the other side there is an adapter (10) with an M32 thread for attaching the extension rod (8) to the rod (6) hydraulic cylinder (1). In this case, intermediate rods with mating threads can be installed between the extension rod (8) and the rod (6) of the hydraulic cylinder for connection to the elements (7) and (10). The manual oil pump is located in the lower part of the hydraulic cylinder (1) and contains the handle (11) of the drive (12) of the oil pump (2). In the upper part of the hydraulic cylinder (1) there is a screw for opening the drain nozzle (13), which is a check valve that prevents the flow of hydraulic fluid (for example, technical oil) from the working piston into the cavity of the hydraulic cylinder (1). Two handles (14) are welded in the center of gravity of the device for transportation.

The device operates as follows.

The device is placed taking into account the hardness of the soil in the immediate vicinity of the support, from the side of the slope of the overhead line support. From the opposite side, excavation is carried out manually. The intermediate rods of the required length are assembled. The U-shaped bracket (9) of the extension rod (8) is emphasized in the support body. Moving the handle (11) of the oil pump (2) drives the rod (6) of the hydraulic cylinder in a forward motion. The pushing force is transmitted from the rod (6) through the intermediate rods and the extension rod (8) and the U-shaped bracket (9) to the support. The work of the oil pump (2) is continued until the support takes a vertical position. After leveling the support, the soil is backfilled with tamping. After compaction of the soil, unscrew the nozzle screw (13) to lower the stem to the lower position.

The essential distinguishing features of the claimed device are:

- the device is fully mobile;

- the device is universal for any cross-sectional shape of supports (circle, square);

- the device has a blocking of the lowering of the working rod under the pressure of the support.

The claimed essential distinguishing features are unknown to us from patent and scientific and technical information and, accordingly, are "New".

Working drawings, strength calculations were made for the claimed device, and a prototype was manufactured, which was successfully tested at the facilities of Gazprom transgaz Ukhta. In this regard, the device declared by us meets the criterion "Industrial applicability".
