SU2912A1 - A device for turning trolleys, driven along the rails by a rope or chain - Google Patents

Description

In case of railways with cable or chain trails of individual trolleys, it is very difficult to transfer them from one route to another, without uncoupling from traction, due to the fact that, usually, it is necessary to make a translation along the arc of the minimum radius allowed by the base of the trolley; Under these conditions, the trolley wheels, moving along circles of different radius, experience considerable friction and, therefore, wear on the track and rolling stock. In order to eliminate these inconveniences, the author applies a transfer carriage on which a trolley is installed and which, benefit, the small diameter of wheels set radially describes an arc of a circle around the outer circumference of a pulley supporting a pull rope or chain. FIG. 1-3, the proposed device is depicted in: three projections: in vertical, in plan and on the side. At the pulley J8 of the cable conveyor, standing at the place where the trolley 20 is transferred from one path 27 to another 22, a trolley / is installed, on the upper platform of which the ends of the rails are attached, which serve as a continuation of the rail track 27, so that the trolley 20 delivered on rails 27, freely rolled in and mounted on the trolley. The carriage, radially mounted wheels 13, forcibly describes together with the carriage a circle concentric with the pulley 18. The carriage is pulled on the carts by 7 tons of cable, enveloping 1PKIV 18. When the carriage is upturned by the front wheels to the stopper 2, held in place by lever 3, will move away lever 75, will turn the shaft 5 and slide the valve 6, holding the cart in place, the cart comes in a circular motion around the pulley. During the rotation of the trolley, the weight 7, suspended from the trolley and slung over the rollers 77, 70, 9 and 8, is lifted. Having described the required curve against the rail 22, the trolley opens the stopper 76 allowing the car to go off using the slider 72, lever 77 with rail carts on rail

track 22. and the load 7 returns the cart to its initial position with respect to the rails 2 with its body.

PRED M E T P A g N N t l.

A device for turning trolleys driven along the rails by a rope or chain, characterized by the use of a trolley / with a section of rails on it, describing on wheels 13 with radial axes, a circular path, the radius of the driving pulley 18, and provided with a lever 3 and a stopper 2 to hold on it the trolley moving the lever 15 when it is moving, unlocking the shaft 5 by turning the shaft 5, preventing the movement of the carriage 7, which carts at the end of the turn abutting track 72, which opens the lever 77 and releases the stopper 16, an obstacle to the descent of the trolley, and during movement it lifts the load 7, guided by the rollers 8, 9, 70, 77 and returns the empty trolley 7 back.
