The conveyor drive, mainly tape

 

(57) Abstract:

Usage: the invention is intended for heavy-duty conveyors with different traction and load-carrying bodies in the coal and mining industry. The inventive conveyor drive, mainly tape contains a drive pulley connected to the two motors through gears with a clutch, two-stage planetary gearbox with a moving planet carrier and the Central wheels are made with different diameters and rigidly connected with low-speed shafts of the respective gears, while the movable carrier is rigidly attached to the sprocket or gear for transmitting rotation of the drive drum of the conveyor. 1 Il.

The invention relates to a conveyor to transport and can be used in such industries and production, using conveyors with different traction and load-carrying bodies.

Known drive device conveyors with one or two driving drums, gears, couplings and motors. Drive motor power must ensure that the start of the conveyor with a full load of the tape, i.e., under the obstruction [1] However, after R is of the motor is already fully used and it works with incomplete download. As a result, during continuous operation of the conveyor is increased energy consumption, which reduces the efficiency of the conveyor. The use of two-speed motors does not provide the necessary low order of magnitude less than estimated, the creeping speed loaded load-bearing body at the start of the conveyor. In addition, two-speed motors are special equipment, so the high cost and scarcity restricts their use.

The purpose of the invention to attain the creeping speed of the loaded tape with multiple launches of the conveyor below the dam and the estimated speed of the tape at the steady state continuous operation on a single motor, which ensures efficiency of energy consumption and reduction of loads on structural elements of the conveyor when it starts.

For this purpose, the leading element of the drive unit is made in the form of a two-line planetary gear, each of the two Central wheels with different diameters are rigidly connected to the low speed shaft of the corresponding gear, and rolling stock cage leading link rigidly fixed sprocket or gear for transmitting rotation of the drive drum of the conveyor.

Nivodnaha drum 1, mounted on bearings 2, is rigidly fixed to the sprocket 3 for the standard drive chain 4 (stub-roller or krupasindhu). Steam sprocket 5 is rigidly fixed to the moving body 6 and a two-line planetary gear, which is mounted in bearings 7 and is a planet carrier. Inside the split housing-led 6 has two Central wheels, the diameter of which varies. Central wheel 8 is rigidly connected with the low speed shaft of the gearbox 9. Central wheel 10 is rigidly connected to the low speed shaft of the gear 11 through the clutch 12, located between the branches of the carrying belt 13. Dvuhventsovye satellite 14 kinematically connects the two Central wheels 8 and 10. High-speed shaft of the gear 9 is driven by a motor 15 through the clutch 16, the high-speed shaft of the gearbox 11 is driven by a motor 17 via a coupling 16. The power of each motor 15 and 17 are approximately the same. Each motor shall ensure continuous operation of the conveyor at the established design speed of the carrying tape. The gears 9 and 11 are standard and can be either worm or cylindroconical.

The work of the proposed drive unit osushestvlyaetsya 15 and 17. Low-speed shaft gear 9 causes the rotation of the Central wheel 8, and the low speed shaft of the gearbox 11 Central wheel 10. Due to the difference of the diameters of the Central wheels 8 and 10 dvuhventsovye satellite 14 begins not only to rotate but also to our teams around a smaller Central wheel 10 in the direction opposite to its rotation. As a result, the housing-led 6 two-line planetary gear starts to rotate, which is transmitted to the drive drum 1 through the sprocket 5 and 3 and the drive circuit 4. Due to the fact that the diameters of the Central wheels 8 and 10 differ slightly, the rotational speed of the housing-led 6 will be small, and the speed of the loaded tape 13 is creeping, which reduces the load on the structural elements of the conveyor, and the conveyor belt. When the conveyor belt will begin to move throughout its course, and with the tape begins to move carriages and goods can move on to the pipe with the estimated speed. It is enough to de-energize the motor 11. With this Central wheel 10 will be fixed and speed spinning his dvuhventsovye satellite 14 will increase. Thus the speed of the tape 13 will reach a settlement.

The proposed construction of a drive service unit optional as in the case of both of the motors 15 and 17 both Central wheel 8 and 10 will be fixed. The housing-led 6 will also be fixed, as dvuhventsovye satellite 14 cannot rotate due to the difference in the diameters of its crowns.

In addition, the presence of a drive unit of the creeping speed when turning on both of the motors 15 and 17 facilitates and accelerates the repair work when replacing a worn conveyor belt.

After the start of the conveyor on the two motors 9 and 11 off one of them for long-term operation of the pipeline with an estimated speed of the tape is possible using, for example, time relay, i.e., automatically without human intervention.

The CONVEYOR DRIVE, MOSTLY TAPE, including drive pulley connected to the two motors through gears with clutches, characterized in that it additionally has a two-stage planetary gearbox with a moving planet carrier and the Central wheels are made with different diameters and rigidly connected with low-speed shafts of the respective gears, while the movable carrier is rigidly attached to the sprocket or gear for transmitting rotation of the drive drum to
