Description

Cable-conveyor-belt constructions are known;} with a load-carrying tape freely supported on the cable traction unit. However, the traction efforts developed by them are insufficient.

In order to eliminate this drawback in the described construction of the cable-conveyor belt, the traction body is made in the form of a cladding system closed in an endless loop. In order to ensure the tension of the traction body when the electric winch is automatically switched on, a ta.hogenerator is used that interacts with the carrier tape, at a decrease in the speed of which the voltage developed by the generator acts on the winch activation system.

FIG. 1 shows the schema of the cable-conveyor belt; in fig. 2-principle electrical control circuit of the automatically activated electric winch, tension of the rope body.

The rope-belt conveyor has a traction device 1, made in the form of a multi-branch rope system, the rope 2 of which repeatedly bends around the drive blocks 3 and the tension blocks 4. The ends of the rope 2 are connected through the diagonal pulley 5.

The carrier tape 6 lies loosely on the pull rod / and is connected to it by frictional forces. Belt tension 6-load. For tensioning the rope 2, an electric winch 7 was used, including automatically.

When the cable-belt conveyor is turned off, the electric motor 8 of the winch 7 is disconnected from the network, since the coil circuit 9 of the contactor 10 of the starter is open normally open b.youx-contact 11 of the general mains switch of the conveyor drive. When the conveyor is turned on, as well as if the tension of the rope 2 is too weak, the normally closed contact 12 of the executive relay 13 is relay

The force-lock 14 ihngyrust start-up button 15 of the contactor 10, the coil-9 circuit closes, as a result of which the electric motor 8 starts to work, and the winch-7 moves the tension blocks 4 until the rope 2 has received the tension, and the belt is not 6 will not increase speed. The tachogenerator 16 interacts with the tape 6. We develop the emf with it. Proporiopal speed change tape 6.

Simultaneously with the achievement of the rope 2, the required tension emf. tachogenerator 16 will reach the nominal value of 1, so that the executive relay 13 will open contact 12, thereby disconnecting the electric motor 8 from the setpoint. Winch 7 will stop and further tension on the rope 2 will not occur. Button 15 is used for manual start, and button 17 is for manual stopping of electric motor 8.

Claims (2)

1. A rope-transport 1N transport line with cargo-carrying tape, which is loosely supported on the cable traction body, is designed so that, in order to increase the SAFETY force, the traction body is made in the form of a multiple-leg system, closed in an endless loop. 2. The form of performance of the kaiat-belt conveyor according to claim 1, characterized in that, in order to ensure tension of the traction organ with the help of an automatically activated electric winch, it is made with a tachogenerator interacting with the carrier tape, while reducing the speed of which it develops. their voltage affects the electric winch starting system. /five : L / : 2; // /
