Изобретение относитс к области подъемногтранспортных машин и может быть использовано в конструкци х конвейеров , имеющих ленточный или ему подобный т говый орган.The invention relates to the field of hoisting machines and can be used in the construction of conveyors having a belt or the like traction body.

Известен привод ленточного конаейера , содержащий приводной барабан, который на дуге его огибани конвейерной лентой охватывают прижимные бесконечные ремни, расположенные ларал- Q лельно Друг другу и взаимодействующие с отклон ющими катками, имеющими скобы, через которые пропущен трос с установленными на его концах пружинами ,11 15The belt conveyor drive is known, which contains a drive drum, which on the arc of its bending around the conveyor belt encompass pressure endless belts, which are arranged parallel to each other and interacting with deflecting rollers having brackets through which the springs are mounted with its springs 11 15

Однако в .этом приводе не обеспечиваетс регулирование т гового усили привода конвейера в зависимости от изменени усили в конвейерной ленте, вызванного, например, изменением тру-20 зопотока.However, in this drive, the traction force of the conveyor drive is not controlled depending on the change in force in the conveyor belt, caused, for example, by a change in the workflow of the flow.

Наиболее близким техническим решением по совокупности признаков и достигаемому эффекту вл етс приводThe closest technical solution for the combination of features and the effect achieved is the drive

ленточного конвейера, включающий приводной барабан, охватываемый конвейерной лентой, контактируемой с прижим ными лентами, огибающими рамки, установленные на раме, и прижимной меха низм, выполненный в виде гидроцилиидров , которые присоединены параллельно к нагнетательной и сливной магистрал м гидромотора привода барабана 23.belt conveyor, which includes a drive drum covered by a conveyor belt in contact with pressure tapes, frame envelopes mounted on the frame, and pressure mechanism made in the form of hydraulic-hydraulics, which are connected in parallel to the discharge and drain lines of the drum 23 drive motor.

Однако наличие гидроцилиндров, насосов и гидромоторов приводит к услож- нению конструкции привода, а расположение гидроцилиндров в одной плоскости увеличивает габариты устройстваHowever, the presence of hydraulic cylinders, pumps and hydraulic motors makes the drive design more complex, and the arrangement of hydraulic cylinders in one plane increases the overall dimensions of the device.

Целью изобретени вл етс упрощение конструкции привода.The aim of the invention is to simplify the design of the drive.

Claims

This goal is achieved by the fact that in a belt conveyor drive 7 comprising a drive drum covered by a conveyor belt in contact with pressure tapes, envelopes of the rollers mounted on the frame, and the pressure mechanism, the rollers are mounted on the frame by means of t, and the pressure mechanism is designed as a rotary the axis of rotation of the drive drum of the bracket, kinematically associated with the pivoting rods and having a flow, arranged with the possibility of contact with. conveyor belt. The drawing shows a General view of the drive belt conveyor. The drive of the conveyor belt contains a drive drum 1, circumscribed by a conveyor belt 2. On a frame in the form of a disk 3, axles k are eccentric to the axis of rotation of the drive drum and there are sprockets 5 on which swivel rods 6 are mounted, carrying rollers 7 on the second ends, pairwise bending around the clamping ribbons 8. Each pair of rollers is interconnected by means of 9 °. An asterisk 1 1 with a bracket 12 mounted on it is coaxial with the shaft 10 of the drive drum, the asterisk 11 is mounted on the “shaft 10 freely. The sprockets 5 and 11 are kinematically connected to each other, by a chain 13. At the second end of the bracket 12 on axis 1, mounted on the slots of the bracket, there is a roller 15, which interacts with the incoming branch of the tape 2. The rollers 7 are mounted in swivel joints 6 on axle x16 The conveyor drive operates as follows. When the driving drum 1 is rotated, the incident branch of the tape 2 acts by means of the roller 15 onto the bracket 12, turning it clockwise at a certain angle. The sprocket 11, turning clockwise, by means of the chain 13 turns the sprockets 5 with swiveling rods 6. The rollers 7, turning clockwise, press the belt 2 to the drive drum 1 with the pressure bands 8, and the pressing force is greater than more force in the oncoming branch of tape 2, depending on the load on it. Consequently, this drive automatically adjusts the pull 9 44 force depending on the force in the incoming branch of the conveyor belt. The arm of the bracket 12 is changed by moving the roller 15 along the slits, it is possible to change the dependence of the driving force of the drive with a constant force in the oncoming branch tape 2. In this case, the torque applied by the pivot point 6 and hence the pressing force changes. tape-2 to the drive drum. Such an embodiment makes it possible to reduce the dimensions of the drive, increase the life of the conveyor belt by reducing the specific pressure between the pressure tapes and the conveyor belt, increase the reliability of the drive and change the dependence of the pulling force, the drive with a constant force in the incoming branch of the conveyor belt. This will make it possible to obtain significant traction efforts with a small effort in the oncoming branch of the traction organ. Claims of the Invention A belt conveyor drive comprising a drive drum covered by a conveyor belt in contact with pressure tapes, envelopes of rollers mounted on a frame, and a pressure mechanism characterized in that, in order to simplify the drive design, the rollers are mounted on the frame by means of turning t g., and the clamping mechanism is made in the form of a bracket drive drum rotatable relative to the axis of rotation, kinematically connected with rotational drafts and having a roller mounted with tact with the conveyor belt.
