SU1668242A1 - Self-propelled bunker for charging belt conveyer - Google Patents

Abstract

The invention relates to a lifting and transport equipment and allows to increase the productivity and reliability of operation. The self-propelled bunker includes a portal 3, a feed funnel 1 mounted on it, gearboxes (P) 7, suspension roller supports 2 and running wheels 14. The latter are kinematically connected to P 7 that have reversing mechanisms, pressure devices (PP) 6 in the form of springs, the movement mechanism, made in the form of rubberized rollers (RR) mounted on the shafts of R7 4. With the help of PP 6, the PR 4 is constantly interacting with the working surface of the conveyor belt 5. The roller supports 2 are located below the working surface of the conveyor belt 5, and OP 4 is above roller carrier 2. The material is fed into the funnel 1, from where it enters the conveyor 5. When the material is loaded into the funnel 1 from the moving device, when the reversing mechanisms are switched, the rotation is transmitted from the OP 4 through the R 7 to the wheels 14 and the portal 3 moves. the other side is switched reversing mechanism. 3 il.

Description

The invention relates to a lifting machinery, in particular to self-propelled bunkers used for loading material onto conveyor belts.

The purpose of the invention is to increase productivity and reliability.

FIG. 1 shows the described self-propelled bunker, a general view, in Fig. 2 - a view A in Fig. 1; fig.Z - reverse gear (in the on state)

The self-propelled bunker contains a feed hopper 1, suspended roller supports 2 in the form of rollers pivotally interconnected, mounted on portal 3 (figure 1).

The movement mechanism is made in the form of rubberized rollers 4, which are constantly pressed against the working surface of the conveyor belt 5 by clamping devices b, made, for example, in the form of springs (figure 2), interacting with gearboxes 7 mounted on the portal 3. The rollers 4 are located above the suspended roller 2 and rigidly mounted on the input shafts of the gear 7. The roller 2 is placed under the working branch of the conveyor 5.

Each gear 7 is provided with a reversing mechanism 8 (changing the direction of rotation of the output shaft when

rotation of the input shaft in one direction), made, for example, in the form of a block — conical wheels 9, mounted on a splined sleeve 10, which is mounted on the splines of the output shaft 11 with the possibility of axial movement using a control lever 12 fixed from three positions clips 13 (fig.Z)

The output shaft of the gearbox is connected to the driving wheel 14 by a kinematic connection, for example, in the form of a chain transmission 15.

Self-propelled bunker works as follows.

Being in working condition, the bunker takes the material from the rotary excavator or material handler and loads it onto the belt 5 of the conveyor belt. In this case, its rollers 4, in contact with the belt 5, come into rotation and transmit torque through gearbox 7 and chain transmission 15 to the traveling wheel 14. As a result, the hopper moves along rails laid on both sides of the conveyor, for example , behind the rotor excavator as far as working the bottom.

If it is necessary to stop the hopper, the block of the bevel gears 9 is disengaged from the bevel gear located on the input shaft of the gearbox using the control lever 12 and is set in the middle position when none

of the wheels of the block does not interact with the bevel gear.

The torque from roller 4 is not transmitted to the sprocket 15 of the chain transmission 15.

In order to prevent spontaneous activation and deactivation of the block of conical wheels, the lever is arranged to be locked in three positions by latches 13, made, for example, in the form of fingers.
