Description

This invention relates to the field of part-shot treatment.

The purpose of the invention is to increase durability by protecting the current-carrying contacts when using the device in cleaning chambers.

FIG. 1 shows the cart, general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one.

Trolley 1 enters the shot-blasting chamber 2, moving along the track 3 by means of a pulling chain 4, the ends of which are fixed on the trolley. On the cart there is an electromechanical drive for rotating the table 5, which contains an electric motor 6, a reducer 7 and a bristle 8. At the bottom of the rotary table 5 there is a gear ring 9 with internal gearing, interacting with gear 8.

In the middle and in the lower part of the trolley there is a pocket 10 in which a block 12 with current-carrying contacts 13 is mounted on springs 11 and connected with cable 14 with an electric motor 6. The bottom of pocket 10 is closed with a night rubber seal 15. Block 12 is made in the form of prism.

In the middle of the rail track 3, chambers 2 are mounted in a vertical position, the connecting device, consisting of a plug 16 with current-carrying contacts 17, a hollow rod 18 and a power cylinder 19. The plug 16 is installed inside the head 20 with the possibility of movement by means of a spring 21. The rod 18 is movably mounted in the housing 22 and connected with its lower end to the power cylinder 19. The upper part of the housing 22 and the head 20 are made in the form of a wedge. The housing 22 is closed on top of the one hundred night rubber seal 23.

A cable 24 connecting the current-carrying contacts 17 to the camera control panel 2 is passed through the hollow shaft 18. In addition, the rod 18 is provided with a pipe 25 connected to the chamber 2 pneumatic system, and air inlets 26 and 27 are provided in the plug 16 and the head 20.

The trolley is operated as follows.

In the initial position, the trolley 1 is located outside the chamber 2, and the pocket 10 in which the block 12 is installed is closed by a night seal 15. The current-carrying device is in the lowest position, while the spring 21 is decompressed, allowing the current-carrying contacts G7 to be inside the head 20, which, in turn, is located in the cavity of the housing 22, which is closed by a hundred-night seal 23.

On the trolley 1 set to be cleaned product. Depending on the nature of the product being cleaned, the trolley may perform a reciprocating (shuttle) movement or is set to a middle position and a rotational movement is attached to its table.

In the reciprocating movement of the carriage 1, the carriage 1 is driven by a drive (not shown) of the traction chain 4, after the cleaning cycle, the car comes out, stops and unloads.

If it is necessary to rotate the product to be cleaned, the cart rolls into the middle position of the chamber with the drive of the traction circuit 4 and automatically stops. The power cylinder 19 is turned on with simultaneous air supply through the nozzle 25 into the hollow rod 18, the rod rises together with the head 20, revealing a one-night seal 23 along the path. Then the one-night night seal 15 touches the head 20 of the block 12 which is centered relative to the head 20 in the horizontal by means of springs 11. upon further movement of the rod 18, the spring 21 is compressed and the current-carrying contacts 17 enter from the head 20, and the current-receiving contacts 13 of the block 12 are closed.

From the control panel, a voltage is applied to the cable 24, which is transmitted through closed contacts to the cable 14 connected to the electric motor 6. The electric motor begins to rotate through the gearbox 7, the bristle 8 and the gear 9 to the table 5 with the product to be cleaned attached to the rotational motion.

Simultaneously with the inclusion of the power cylinder 19 through the pipe 25 into the hollow shaft 18, air is supplied, which through air channels 26 and 27 enters the pocket zone 10, blowing the contacts and creating excessive pressure in it, thereby preventing the shot and dust from entering the contact zone. An additional fractional protection is provided by a night overhead seal 15, which fits the hollow rod 18, seals the pocket 10. After cleaning the product, the voltage supply is stopped, the turntable 5 of the trolley 1 is stopped and the current supply device is reset. At the same time, the air supply to the bar 18 is stopped. Then the cart with the processed product rolls out of the chamber, stops and unloads.
