Abstract

The invention relates to lifting devices, in particular, intended for servicing lighting devices located in hard-to-reach places, and allows for accurate installation of the light source and reducing the labor intensity of the service. The device includes a carriage on which a bar with a light source is mounted. The carriage is mounted for movement along rails having upper and lower mounting elements. The position of the light source in the focus of the optical system is adjusted by means of a set-up sighting device, and then the working sighting device is set up, which allows the light source to be adjusted when the carriage is fixed by the lower mounting element.

The invention relates to lifting mechanisms intended for the maintenance and installation of light-proof devices located in difficult places, and is in addition to auto-installation. No. 1331976,

The aim of the invention is to provide accurate installation of the luminous body of the light source in the focus of the optical system and reduce the complexity of this process.

Fig. 1 schematically shows a tower with a device for servicing and adjusting a light source; figure 2 - node 1 in Fig. 1; on fig.Z - section aa in figure 2; figure 4 - view B in fig.Z; in FIG. 3 - view B on. Fig 3; figure 6 is a view of G in fig.Z; in Fig. 7, the node P-in in Fig. 8 is a view of D in Fig. 7; figure 9 is a view of E in Fig.7.

The device includes a carriage 1, which is mounted on guides 2 with the possibility of vertical movement. On the carriage 1 is mounted

rod 3 with a source of 4 light. On the guides 2 are located the upper 5 and lower 6 mounting elements.

In the design of the structure, for example, a star installed in the upper part of the tower, a removable set-up sight device is provided, consisting of sights 7 and 8, equipped with a solid 9 and a broken 10 crossings, with the help of which the axis of the optical system is sighted. In viewfinder 7, in addition to the torn cross, there is a frame 11.

At the bottom of the tower, there is a working sighting device installed on the frame 12 with a folding stand 13, on which adjustable working viewfinders 14 and 15. are located. Work viewers 14 and 15 are equipped with a crosshair 16 and 17. The crosshair 16 is solid; and crosshair 17 is broken, with a frame 18 in the center of crosshair 17.

To ensure uniform illumination of the entire surface of the glazing - the star, an optical system 19 is provided by which the luminous flux of the light source, the photometric body of which has an approximately toroidal shape, is converted into a five-petal photometric body, each of the petals of which is directed along the corresponding star beam. ,

The device works as follows

At the initial installation of the light source 4, it is fixed on the rod 3 and, moving the carriage 1, brings it to the extreme upper position fixed by the stop 5. At the same time, the light source 4 mounted on the rod 3 falls into the center of the optical system 19 stars, which is a prerequisite for proper operation of the light-optical system, ensuring uniform illumination of its glazing, namely, the coincidence of the center of the luminous body of the lamp with the focus of the optical system, as well as the presence of the necessary azimuthal orientation of the luminous body tnositelno the main plane of the star.

Optimum operation of the optical system is achieved by adjusting the height and azimuthal position of the heating body 20 so that it best fits the size of frame 11 of the set-up viewfinder 7. After that, the position of the light source 4 relative to the carriage 1 is rigidly fixed, since this position of the heating body 20 is the working sights 14 and 15 are used as reference for adjusting the working light sources 4 adjusted in this way. The carriage 1 is lowered down to the bottom abutment 6, and the working viewfinders 14 and 1 are set as the reference light source. 5 in a similarly described manner with respect to the position of the filament body 20.

When the light source 4 is subsequently changed, the installation and its adjustment are carried out in the lower part of the tower with the help of working sights 14 and 15. The light source is adjusted when, as a result of tuning, its glow body 20 is clearly visible through frame 18, as if inscribed in it. I

The source of light 4 installed in such a way relative to the carriage 1, when the carriage moves to the upper abutment 5, transfers the exact adjustment of the height of the light center and the required azimuthal arrangement of the filament body to the center of the star's optical system

Using the proposed device provides the ability to accurately install the light source with
