Description

one

This invention relates to emission spectral analysis.

A device for spectral analysis is known, comprising interchangeable working bodies mounted on a vertical frame connected to a rider, each of which contains devices for longitudinal, transverse and vertical displacement of the electrodes, and their mutual arrangement is specified using special adapters.

However, the known device does not allow performing any analysis on a single tripod and does not provide a sufficiently high performance as well as operational safety.

The aim of the invention is to ensure that any spectral analysis is performed on one tripod, increasing productivity and ensuring safe operation.

For this purpose, a guide is mounted on a vertical stand with the possibility of being installed in any plane, the electrodes' moving units are hingedly connected to the vertical stand and a guide mounted on it.

The invention is illustrated in the drawings.

FIG. 1 shows a diagram of a tripod made in the variant of the triple arc; in fig. 2, 3 - kinematic scheme and the relative arrangement of parts of a unified worker

body; in fig. 4 is a remote control circuit.

The tripod to the spectrograph contains a vertical tubular stand I, which is fastened by a rotating clip 2 to a feeder 3 fixed on the rail. Clamp 2 allows the rack 1 to be removed from the plane of the optical axis. To the rack 1 by means of a unified hinge 4 is mounted a tubular crossbar

5. The same hinges 4 fasten the unified working bodies to the rack 1 and to the crossbar 5 6. The hinge 4 consists of two split clamps connected with a screw and gaskets, allowing you to rotate one half of the clamp 4 relative to the other and fix at different angles. One half of the hinge 4 captures the rack 1 or the crossbar 5, and the other clamps the case of the drive mechanism 7, thereby holding

unified working body 6 in a predetermined position. The working body 6 consists of a drive mechanism 7, a swivel head 8, an electric holder 9 and a unified hinge 4. Four such assemblies are mounted

on the rack 1 and the crossbar 5 at a predetermined position, the hinges 4 allow you to quickly change the relative position of the electrodes or to remove the unit from the tripod. Each working unit 6 provides one electrode with three independent, mutually perpendicular movements: the main adjusting movement in the direction of the electrode combustion is by means of a rotary head 8 and moving along the axis of the electric holder of the holder 9 mechanism. The drive mechanism 7 consists of the remote control motor 10 ( see Fig. 2), in which the slider 12 reciprocally moves, receiving movements from the screw 13 connected to the electric motor 10. The swivel head 8 is mounted on the upper end e slider 12 and provides capture in the desired position of the electric motor 10, as well as the transverse rotational movement of the electrode with the screw 14 (see Fig. 3) and the spring 15.

The holder 9 provides the capture of the electrode 16 (see Fig. 2), the current supply of the current-carrying parts from the body and the reciprocating movement of the electrode along the axis of the holder.

The electrode is gripped using a ceramic rod 17, a spring 18, and a current-carrying stop 19. The correction movement is carried out using a screw 20 and a yoke 21.

All four main disarms are controlled remotely from the four-keypad. Motor 22 (see Fig. 4) is connected to the console via connector 23, turned on, off and reverse by means of microswitches 24 using a key 25 having three respective positions.

An adjustment resistor 26 serves to provide a smoother feed while maintaining a quick return. Power is supplied via connector 27, reversing and adjusting the speed is carried out in a dep. Box.

The proposed tripod provides an analysis of waking and evaporation using vertical, horizontal, double, triple and three-phase arcs at high operating currents with remote control in all variants and allows you to switch from one method to another without adding or removing new nodes.
