SU819000A1 - Device for intermediate load-relieving of belt convejer - Google Patents

Description

one

This invention relates to the field of industrial transport.

Devices for unloading belt conveyors are known, including sliding knives and a drive for controlling them, located on the carriage 1 moving along the conveyor axis.

In the event of a drive failure, the belt conveyor has to be stopped, which disrupts the process.

The closest in technical essence and the achieved result to the invention is a device containing a plow with a drive in the form of an electric motor connected to the input shaft of the gearbox via a pulley and a V-belt transmission 2,

A disadvantage of this device is the impossibility of uninterrupted operation in an emergency situation and during repair work.

The aim of the invention is to ensure uninterrupted operation of the device.

The goal is achieved by the fact that the device is equipped with a manual drive, made in the form of a flywheel and two overrunning clutches rigidly interconnected, the internal clips of which are fixed to the input shaft of the gearbox, and the outer drive camshaft gear and flywheel are mounted on the external clips.

FIG. 1 shows a general view of the described device; in fig. 2 — node I in FIG. one; in fig. 3 shows a section in FIG. 2

The device for intermediate unloading of belt conveyors contains a plow 1 and a drive consisting of an electric motor 2, a V-belt drive 3 and a gearbox 4. In an emergency or during repair work, the device can be operated from a manual drive including an overrunning clutch, the outer sleeve of which is a pulley 5 (FIG. 2) of a V-belt transmission, wherein the inner race 6 is mounted on the input shaft 7 of the gearbox and is rigidly connected to the inner race 8 of the second overrunning clutch, the outer flywheel of which is performed by the flywheel 9. Inter In the inner and outer collars clutches 10 are located. On the output shaft of the reducer there is a crank 11 (fig. 1), through which plow 1 rises and lowers through pu 12.

The design of the overrunning clutches used in the drive provides for the working rotation of the V-belt pulley or the flywheel clockwise and the idle rotation counterclockwise.

With the electric motor inoperative, raising or lowering the plow 1 is performed by manually turning the handwheel 9 clockwise. In this case, the rollers 10 are wedged between the flywheel and the yoke 8, which, through the yoke 6, transmits torque to the input shaft of the gearbox 7. The output crank 11 is pulled by means of the pull 12 by raising or lowering the plow. When the hand drive is in operation, the sleeve 6 rotates relative to the pulley 5.

Safety from manual operation in the event of a sudden start of the electric motor is ensured by a higher rotational speed of the pulley and correspondingly of the holder 8 compared to the flywheel, which, overtaking the flywheel, rotates relative to it idle.

The device ensures uninterrupted operation of the belt conveyor in the event that the device’s motor fails or is de-energized.

The main advantage of this manual drive compared with the known manual drive is its safety during operation.
