Description

The invention relates to the field of antenna technology, in particular, to mounting devices and methods for adjusting the position of reflective shields of large-sized reflectors of antennas of terrestrial communication systems.

The well-known design (Pole BC, E. Berwalds. Precision design of mirror radio telescopes: Experience of creation, problems of analysis and synthesis. Monograph. - Riga: Zinatne, 1990. - 526 p., Page 295, Fig. 5.33 and page 296 - last paragraph ) a support device for the reflective shield, containing a screw fixedly mounted on the shield, spherical washers, lower nut and upper lock nut, as well as a gap in the hole to compensate for the position of the screw.

The disadvantage of the above construction is the complexity of its settings in a limited space and difficult access to the adjusting elements of the support device. The design described above requires first installing the lower nut in the desired position, then locking it with the upper nut. The end result is a decrease in the accuracy of the installation of reflective shields.

A known method of adjusting the support device (RF patent 2167473) of the reflective shield, providing for the installation of the support device on the element of the power frame, the spatial alignment of the screw and the device lock.

The disadvantage of the above method is the lack of the ability to simultaneously install the key on two fasteners (hexagon) to adjust them, which in difficult access conditions leads to a complication of the process, increased labor intensity, reduced labor productivity and reduced accuracy of installation of reflective boards.

The technical problem to be solved is the creation of the design of the supporting device of the reflective shield and the method of its adjustment

allowing to simplify the installation process and adjust the position of the reflective shields of large-sized reflectors of antennas of terrestrial communication systems, thereby increasing usability and labor productivity. The problem is solved as follows.

The supporting device of the reflective shield contains a screw, which is fixedly mounted on the shield, for example, glue-mechanically. A split nut sleeve is installed on the free end of the screw. The sleeve nut contains split and integral sections. A collar is made on the split section, on one of its sides there is a spherical surface for interfacing with a conical washer. Spherical and conical washers are sequentially mounted on the integral section of the sleeve nut. At the end of the whole section, a hexagon is made. There is a gap between the sleeve nut and the spherical and conical washers to provide angular compensation.

The solution to the problem in the method for adjusting the support device of the reflective shield is achieved by the fact that the support device of the reflective shield is installed on the element of the power frame, the screw is spatially exposed and the support device is locked. The new one is that the spatial alignment of the screw is carried out by moving the sleeve nut with the external socket wrench and locking with the lock nut using the internal socket wrench. The foreign key has a larger size of the internal hexagon than the internal key. The handle of the external socket wrench has a tubular section with spacing bushings located inside. Remote bushings are made, for example, of fluoroplastic. Using the remote bushings, the internal key is positioned relative to the walls of the foreign key, as well as their (keys) independent rotation.

The solution to this problem allows us to recognize the proposed combination of objects as satisfying the requirement of unity of invention.

The technical result provided by the given set of features is to increase the accuracy of adjusting the position of the reflective shields of large-sized reflectors of antennas of terrestrial communication systems.

The invention is illustrated by drawings, which depict:

FIG. 1. General view of the supporting device of the reflective shield

FIG. 2. Section AA

FIG. 3. Top view of the support device of the reflective shield

FIG. 4. Device for adjusting the reference device

The support device of the reflective shield mounted on the element of the power frame 1 (Fig. 1), contains a screw 2, fixedly mounted on the reflective shield (not shown in Fig.), A lock nut 3, a spherical 4 and conical 5, 6 washers, as well as adjusting the gaps 7 (Fig. 2) to ensure compensation. A split nut-sleeve 8 is installed on the free end of the screw 2, having a split nut 15 and an integral portion 16. A shoulder 9 is made on the split portion with a spherical surface 10 cut into petals 14 (Fig. 3). The spherical surface 10 is adapted to be mated with a conical washer 5. On the whole area, spherical 4 and conical washers 6 are mounted in series, fixed by a lock nut 3 and a hexagon 11.

The method of adjusting the support device of the reflective shield includes installing the support device on the element of the power cage 1. A nut 8 and a lock nut 3 are screwed onto the screw 2. At the same time, an external 13 and an internal 12 socket wrench are installed on the integral section 16 of the nut-sleeve and the lock nut 3. The internal hex 17 of the foreign key 13 is larger than the hex 18 of the internal 12

the key. The handle 20 of the external 13 key has a tubular cross-section with the remote bushings 19 located inside. They provide spatial exposure of the screw 2 in space by rotation with the internal 12 key, lock the position with the lock nut 3 with the external 12 key.

The operation of the device is as follows.

Fix the screw 2 motionless on the shield. Screw the sleeve nut 8 onto the screw 2, place a conical washer 5 on its split 15 section. Install the assembly on the element of the power frame 1. On the whole section 16, the conical 6, spherical 4 washers are installed sequentially due to the gaps 7, the angular compensation of the position of the screw 2 is provided. Using an external 13 socket wrench with an internal hexagon 17, lock nut 3 is screwed onto the integral section 16 of the sleeve nut. Leaving the lock nut 3 without tightening, then rotate the sleeve nut 8 with the internal 12 hexagon socket wrench 18, twisting it from the fixed screw 2 or screwing it onto the screw 2 using the internal socket wrench 12. After adjusting the position of the reflective shields, use the external socket wrench 13 tighten the lock nut 3. As the nut 3 is tightened, the gaps between the spherical 4 and conical 5,6 washers are selected. The forces acting normal to the surface 10 bend the petals 14, providing immobility in the connection of the sleeve nut 8 and screw 2 through the thread locking.

The method is implemented as follows. Install the support device on the element of the power frame 1. At the same time, an internal socket wrench is installed on the integral section 16 of the sleeve nut 8, and an external 13 socket wrench is installed on the locknut 3. Turn the internal socket 12 key to change the position of the sleeve nut 8 and, accordingly, the screw 2 with a reflective shield, controlling the position of the shield using, for example, a laser tracker Farolasertracker. Upon reaching the desired position, an external socket wrench 13, tighten the lock nut 3.

The creation of the supporting device of the reflective shield and the method of its adjustment serve the satisfaction of one social task, namely, reducing the complexity of installing reflective boards of large-sized reflectors of ground communication systems and increasing labor productivity.
