Description

The invention relates to antenna technology, in particular to mast devices having telescopic elements and equipped with a support having telescopic legs with an element that prevents the legs from sliding.

A mobile telescopic antenna mast with a support is known [1, 2, 3] having a telescopic mast consisting of N square pipes of different sizes inserted into one another, the movement of which is carried out by a manual winch mounted on an external square pipe, which interacts with a support having telescopic legs, consisting of two sections, in which the inner section at the outer end is in contact through a bushing hinge with the sole resting on a horizontal surface, and the outer section with the outer end of the telescopic legs is in contact with the brackets, fixing them in the working and transport position.

A disadvantage of known mobile telescopic antenna masts with a support is that they are designed for use on relatively level, flat surfaces and are not designed for use on slopes.

The technical solution is aimed at creating a mobile telescopic antenna mast with a support that ensures stable installation of the telescopic antenna mast both on a relatively flat surface and on slopes.

The technical result is achieved in that a mobile telescopic antenna mast with a support having telescopic legs is additionally equipped with a telescopic section, while the inner section at the outer end is in contact through a ball joint with a base having a hole in contact with the fixing pin, and the outer section with the outer end of the telescopic the legs are in contact with the brackets, fixing them in the transport and working position with the ability to select the angle of inclination of the legs, while one side of the bracket has six holes along the radius from the hole coaxial with the hole on the other side of the bracket, which at a radial distance has a radius groove with six conical recesses in contact with a lock that has contact with the threaded bushing of the telescopic leg, fixing it in one of the six holes and conical recesses.

The essence of the invention is illustrated by drawings.

In fig. 1 shows a view of the installation of a mobile telescopic mast with a support on a slope; FIG. 2 shows an assembled view of a mobile telescopic mast with a support; FIG. Figure 3 shows section A-A.

A mobile telescopic antenna mast with a support consists of a telescopic mast 1, which has N square pipes of different sizes inserted into one another, a winch 2, which has a manual drive, and supports 3.

The winch 2, which has a manual drive, is fixed to the outer surface of the square tube of the telescopic mast 1 using fasteners (not shown in the figure).

Support 3 consists of four brackets 3.1, four telescopic legs 3.2, with a ball joint 3.3 and a sole 3.4.

Four brackets 3.1 are secured to each other along the contour on the outer surface of the square tube of the telescopic mast 1 using bolts 5, washers 6, nuts 7 and restrictive bushings 8 located on bolts 5. Bracket 3.1 has a hole 3.1.1 on one edge, around which the telescopic leg 3.2 and at a certain radius six holes 3.1.2 fixing the telescopic leg 3.2 in the working and traveling positions, and on the other edge the hole 3.1.3 is coaxial when assembled with hole 3.1.1 at the same radius there is a radius groove 3.1.4 with six conical recesses 3.1.5 located on the same axis with holes 3.1.2.

Telescopic leg 3.2, having three sections of square pipes of different sizes inserted into one another, while at the end of the outer section there are two holes 3.2.1 and 3.2.2, with a distance between them equal to the radius between hole 3.1.1 and holes 3.1.2 , and interacting with the bushing 3.2.3 and the threaded bushing 3.2.4, and at the end of the inner section there is a ball joint 3.3 in contact with the sole 3.4, which has a hole 3.4.1. Each telescopic leg 3.2 is in contact with two brackets 3.1, rotating around the axis of holes 3.1.1 and 3.1.3 on a threaded bushing 3.2.5, interacting with brackets 3.1 using bolts 9 and washers 10. With a threaded bushing 3.2.4 it is in contact with a retainer 11, which fixes the telescopic leg 3.2 in a given position by contacting one of the six holes 3.1.2, the radial groove 3.1.4 and one of the six conical recesses 3.1.5.

A mobile telescopic antenna mast with a support works as follows. From the assembled position (Fig. 2), intended for transportation, the mobile telescopic antenna mast with support is installed in the working position. To do this, the telescopic antenna mast 1 is installed on the surface with the end of the outer square pipe down. Holding the telescopic antenna mast 1, use support 3 to fix it in a vertical position, for which it is removed from the contact of the latch 10 with one of the holes 3.1.2 by rotating the latch 11 along the thread of the threaded bushing 3.2.2, after which the telescopic leg is rotated around the axis of the holes 3.1 .1 and 3.1.3 on bolts 9. In this case, the clamp 11 moves along the radius groove 3.1.4. Having turned the telescopic leg to the required position, the clamp 11 rotates along the threads of the threaded bushing 3.2.2 and comes into contact with one of the holes 3.1.2 and is fixed in one of the conical recesses 3.1.5. Then the locking clamps 12 are turned away, allowing free movement of the sections of the telescopic leg 3.2 until the sole 3.4 comes into contact with the surface, after which a clamp 13 penetrating into the ground is inserted into the hole 3.4.1 of the sole 3.4, and the locking clamps 12 are wrapped giving the telescopic leg 3.2 a rigid position (Fig. 1). The 3.3 ball joint provides the 3.4 sole with tight contact with the surface, regardless of the angle of inclination.

The mobile telescopic antenna mast with a support is ready for installing antenna elements at the end of the telescopic mast 1 and lifting them using a winch 2.
