SU14277A1 - Adaptation for synchronous operation of the distribution mechanisms of steam engines serving the mechanical grate of fireboxes equipped with mercury cataracts - Google Patents

Description

The synchronous operation of the rjapoBbix distribution mechanisms of machines serving the mechanical grate of furnaces equipped with mercury cataracts is meant to dry out, turn on the help and continuously rotate, the shaft is wedged on it with disks that are equipped with dogs, periodically for 1 , his cataract, with the aim of turning him and thereby affecting the distribution of fur, nism.

In FIG. 1 shows a vertical section through a tool; FIG. 2- vertical section of the washer; FIG. 3 is a top view of the device.

The shaft 5, located along the front of the furnaces, is provided at one of its ends with a friction disk 15, which is connected to a adjustable disk 9, rotated through gears by a motor 16. On the shaft 5, against cataract 1 - 2 of each furnace, disks b are wedged, on which, with the aid of the axles 14 ,,, the dogs 8 are fitted, provided with notches 12 for the spring stops 13, whereby the dogs are held in the on or off position.

When the shaft 5 rotates, the pawns 8 mounted on the disks b are periodically hooked onto the protrusion 7 of the corresponding cataract 1-2 and thereby rotate it through a certain angle. A further rotation of the cataract occurs under the action of the reversing load 11, at which point each of the cataracts simultaneously rotates the corresponding distribution mechanism of the steam engine serving the mechanical grates of the furnaces. The adjustment of the speed of rotation of the shaft 5, and hence the simultaneous adjustment of the steam engines, is carried out by moving the disk 9 along its axis; In addition, the speed of rotation of steam engines can be controlled by switching on a certain number of dogs 8.

The subject of the patent.

1. A device for synchronous operation of the distribution mechanisms of steam engines serving the mechanical grate-furnaces equipped with mercury cataracts characterized by the use of

wound along the front of the fireboxes and receiving a continuous rotation of the shaft 5 with disks 6 wedged on it, against cataracts 1-2 of each furnace, equipped with paws 8 for periodically hooking them to the protrusion 7 of the corresponding cataract, in order to turn it under the influence of wood wreck and affecting the corresponding distribution mechanism.

2. In the fixture described in paragraph 1, the use of dogs 8, pivoting about the axles 14 associated with the disk 6 and fitted with notches 12 for the spring stops 13, is intended to inform the mechanism of compliance with an excessive increase in the force for turning one or another cataract and to get an opportunity Turn off all or some of the dogs. 8.

3. In the fixture described in paragraph 1, the application for changing the number of revolutions of the shaft 5 of the friction gear is with a adjustable disc 9.
