Hold-down device for the cable guide in cable-drawn transport systems
A pressure device for conduction of the cable in cable traction transportation systems including a pressure-roller ( 12 ) of the cable ( 7 ) supported elastically on a fixed support ( 2 ) and a counter-roller ( 6 ) supported on the fixed support ( 2 ) is described. In accordance with this invention the counter-roller ( 6 ) is supported in a revolving manner on a roller-holder ( 5 ) articulated at one end to the fixed support ( 2 ) and possesses at the other end guide means ( 8, 9 ) that engage as a running guide an arm ( 10 ) that bears in a revolving manner at one end the pressure-roller ( 12 ) on the side opposite the counter-roller ( 6 ) and is articulated at the other end to the fixed support ( 2 ) with the arm ( 10 ) being pressed by elastic means in the direction of exertion of pressure of the pressure-roller ( 12 ) on the cable ( 7 ).
1. Pressure device for conduction of the cable in cable traction transportation systems including:
a pressure-roller that can engage a cable;
a fixed support that elastically supports the pressure roller;
a counter-roller supported on the fixed support and characterized in that the counter-roller being supported in a revolving manner on a roller-holder articulated at one end to the fixed support, another end of the roller holder possessing guide means;
an arm that bears in a revolving manner at one end the pressure-roller on a side opposite the counter-roller and that is engaged as a running guide by the guide means;
the roller holder being articulated at another end to the fixed support;
elastic means arranged such that the arm is pressed by elastic means in a direction of exertion of pressure of the pressure-roller on the cable.
2. Pressure device in accordance with claim 1 characterized in that the elastic means include a compression spring.
3. Pressure device in accordance with claim 2 further comprising a tie rod located at an articulation of the arm at a particular distance from a rotation point of the arm, the compression spring is in a guide articulated at a rotation point to the support, and the tie rod loads the compression spring in a known.
4. Pressure device in accordance with claim 1 characterized in that the elastic means include a hydraulic cylinder.
5. Pressure device in accordance with claim 1 further comprising a lever articulated around a rotation point to the roller holder, one end of the lever supporting the counter-roller in a revolving manner, another end of the lever comprising holes arranged along an arc of a circle such that the lever is adjustable at preset angular distances about the rotation point, the lever further being lockable by means of fastening pins in the holes.
6. Pressure device in accordance with claim 1 further comprising a conical pulley applied laterally on the counter-roller to tension the cable upon deposit of the cable in a correct position.
