Description

The invention relates to the field of lifting and transport machinery, in particular to the design of friction drives used on conveyor trains. five

Known friction drive conveyor train, in which to regulate the distance between the traction wheels depending on the width of the train carriage, and depending on the required pressing force, each friction wheel is mounted on roller bearings equipped with a system of levers associated with the drive mechanism [1 ]. 15

The disadvantage of the drive of a conveyor train is low reliability due to the occurrence of resistances in the movable support of the friction drive, as well as the possible jamming of its movable part in the guides when the rock gets into them and it is impossible to ensure the same pressing force of the friction drive wheels to the canvas.

Also known is the drive of a conveyor train containing friction drive wheels located on both sides of the running track and installed

on the pivotally horizontal frames attached to the supports

® Noah designs [2].

However, this design has the following disadvantages, namely slippage of the friction wheels relative to the clutch surface, increased wear of the wheels and the train, increased resistance to movement and increased power consumption.

The pressing mechanism is located in the inter-track, and therefore, if the mechanism breaks while the composition is in the drive zone, it cannot be accessed without removing the composition.

The aim of the invention is the automatic regulation of the force pressing the friction wheels to the train.

To do this, the friction wheels are equipped with pivotally attached to the support structure levers, the vertical axis of rotation of which is coaxial with the axes of rotation of the frames, while the levers are interconnected by a force, one end of which is equipped with a sensor for pressing the wheels, and the other end is connected to the drive mechanism.

kinematic drive circuit of a conveyor train.

The drive of the conveyor train contains friction wheels 1, which have drives 2 mounted on a support frame 3, hinged on racks 4 of the track section 5-. The axes of rotation of the friction wheels 1 are installed parallel to the axes of the hinges 6. The friction wheels 1 are equipped with levers 7 and 8 hinged on the supporting structure 9. The levers 7 and 8 are interconnected by a pawl 10. At one end of the thrust there is a mechanism for automatic control of the pressing force wheels, which consists of link 11 and the sensor 12 efforts. At the other end of the thrust 10 mounted drive mechanism 13.

The friction drive operates as follows.

After activating the drives 2, the friction wheels 1 turn on the drive of the pressing mechanism 13, as a result of which the levers 7 and 8 begin to converge, turning the axles of the hinges 6, which in turn rotate the support frame 3 with the friction wheels 1, compressing the lateral surfaces of the conveyor train 14 The friction wheels 1, thanks to the floating suspension of the support frame 3, are centered relative to the longitudinal axis of the conveyor train 14. In this case, the thrust mechanism 10 of the pressing mechanism creates a tensile force in the link 11 with the force sensor 12, which automatically tklyuchaet drive 13 pressing mechanism for achieving the necessary force.

Since the axes of the hinges 6 are parallel to the axes of the friction wheels 1 and perpendicular to the surface of the track 4 of train 14, regardless of the degree of deformation of the tires of the friction wheels, the vector of the peripheral speed of the wheels at the touch point always coincides with the train speed vector, which will ensure the transfer of traction force from the wheels to train be? slips.

Consequently, with such a design of the friction drive, ³ wear of the tires of the friction wheels, train spars and drive power consumption will be reduced compared to the prototype.

With the proposed drive design in the event of a failure of the pressing mechanism, all its parts are available for inspection and repair, and the thrust can be replaced without having to remove the train outside the drive.
