Description

The author's certificate No. 44267 describes the clamp for the upper traction rope of a double rail route. This clip is made in the form of a box with a hinged lid, equipped with a socket for a pull wire, which is clamped by a lid when it is closed.

The present invention proposes a device for automatic unhooking and subsequent attachment of trolleys to an endless upper rope by turning on and off the cable clamp according to the author's certificate No. 44267.

In FIG. 1 shows the proposed device for engaging a cable clamp-front view; FIG. 2- the same side view; FIG. 3 — similarly acting device for turning on the cable clamp, front view; FIG. 4 - the same side view.

The process of coupling the trolley to the rope takes place in two cycles, which take place almost simultaneously. In the first stroke, the cable clamp cover is lifted from the folded down position to the critical point, from which the cover falls under the action of its own weight, gripping the rope. In the second stroke, the hammer strikes the handle and secures the lid.

spring clamp clamp, which achieves complete clamping of the rope.

In accordance with the two-stroke process of attaching a trolley to a rope, and the proposed device for an automatic attachment consists of two parts mounted on both sides of the track (Fig. 1). On one side of the path, on the machine 20 with the console 2 /, a device is installed for closing the cable clamp cover. This device consists of a sleeve 3 with cross-shaped protrusions 6 to which hook-shaped blades 5 are attached. A pulley 2 connected with a transmission / engine is mounted on a common axis with the sleeve 3. When the trolley, on which the cable clamp J8 is installed with the cover 4 folded, is fed, one of the blades 5 of the rotating sleeve 3 picks up the handle 7 of the cover 4 from the bottom and transfers it from the /// position to position II, from which the cover pushes into position / under the action own weight and captures the rope 8, which is at this moment above the nest clamp, thanks to a nominally breaking block} 0 (Fig. 2).

To grip the clamp with the rope, it is necessary to press the cap 4 to the rope so that the

the friction of the rope 8 in the nest clamp was enough for the rope to drag the car behind it. Such a final attachment of the cover to the rope is carried out by hitting the blade hammers 9 with the handle 7 of the already falling cover 4. This hammer device is installed on the other side of the path and fixed on the pole with the console / 5. It consists of a sleeve // to which paddle hammers P are attached to the hinges 12, which are driven into rotation by means of a transmission from the engine.

In position a, the hammer 9 is shown when it hit the handle 7 of the cover 4 and pressed it against the spring bolt 16. After the strike, the lower part of the hammer 9, hingedly attached to its protrusion 77, due to i continuing rotation the device jn is at the same time an obstacle j in the form of a fixed handle 7 of the roof; 4, forced to bend back on the j hinge and sliding off the handle, | hang on the hinge in position b. Upon further rotation, the hammer 9 with its back side (position e) rests on the rear support J9 of the sleeve // and when the angle of inclination of the hammer to the clamp is about 40, then under the influence of the force of gravity it will separate from the rear support bar 2 (. In this position, hammer 9 is struck against the handle of the lid (in position /). Without this ramp 28, the hammer would be bent at the hinge under the influence of gravity and pass by the handle 7 without striking.

To automatically disconnect the clamp, i.e., to release the clamp with the rope, a similar device is used, shown in FIG. 3 and 4.

On the horizontal axis supported by the brackets 25, attached by means of a strut to the uprights 26, a sleeve 30 is mounted, provided with cross-shaped tides 22, to which the blades 23 are bent at the free end.

A pulley 29 is fitted on the same axis as the sleeve 30, which is connected by a transmission 27 to the engine, which causes the blades 23 to rotate uniformly.

At the approach of the trolley with the rope clamp turned on, one of the blades with its bent end picks up the handle 7 of the clamp cover and rotates it from the position / to the // position, from which the cover 4 tilts to the /// position under its own weight. The cable is retracted upward by an inclined block 24 and the trolleys are thus uncoupled from the rope.
