Description

The invention aims to improve the construction of a double-sided bucket, for example, for a cable-tower excavator.

Distinctive feature

The proposed bucket is that it uses two pivot walls (flaps) mounted on both end sides of the bucket in such a way that three movements of the bucket to one or the other side of the front of the bucket "(as it rises, opens the ground passage, and the rear remains in the normal position, closing the exit to the ground.

To control the walls (flaps), they can be equipped with toothed sectors, coupled with a rack, the ends of which are attached to the haul cables with flexible leads.

The swivel walls can be freely suspended on hinges in the form of valves that alternately open under pressure from the ground and close; the action of its own weight.

In the drawing fit. 1 depicts an exemplary design of the proposed bucket at the time of the ground acquisition (side view with a cut

right half), FIG. 2 and 3 - a bucket at the time of unloading to the right and left sides; FIG. 4 shows a second embodiment of the bucket; FIG. .5 - scheme of the cable-tower installation using a double-sided bucket.

The bucket carriage has four rollers / -4, through which it moves along the cable 26, and seven blocks 5-9. The four upper blocks (5 and 6) are paired, and the other three are single. Through block 5, the cable (or chain) of the UO is thrown, by means of which the bucket is suspended on the wheel. Through the blocks 7 and S, tension cables or chains 13 are held, which support the bucket in a horizontal position. Through each pair of blocks 5 and 5, cables or chains U / and / 2 pass through, by means of which the bucket is tilted to the right and left side for unloading. The cables Y / and 12 through the tension blocks 14 are connected to the blocks 15, which move along the non-drying cable by the tension of the pull cables 16 and 17 and, having encountered the brake 18 on their way, stop.

Tensioning blocks continue to move by the force of pull cables and thereby tighten the cables 11

or 12 tilting bucket for unloading primer. The tangling cable 16 moves and tilts the bucket to the left side, and the cable 17 moves to the right side. Tensioning blocks 14 and 15 are fastened with tow cables 16 and 17 and sturdy 19-19.

Harness cables 19-19 connect tensioning blocks 14-14 with a bucket and simultaneously with cables 13, 20. Cables 20-20 connect Cremallera 21 with tension cable 19 and serve for turning with a yoke and gear sectors 221123 of dampers 24 to 25, i.e. to open and close the bucket.

A reversible cable-tower excavator consists of a three-drum winch, a head and tail bachet "or masts with blocks fixed on them and a system of cables with a double-sided KOVSHM1 (Fig. 5). Bashy 27, on which the winch is installed and controls the excavator, is called the head, and the second tower 29 is called the tail one. Towers (they can be movable - on tracked or railway tracks, stationary - in the form of masts and columns, and nodal towers mounted on pontoons. Both towers - head and tails. - equally serve the load of the bucket. , a carriage, to which a double-sided bucket is suspended, moves. One end is laid, its cable is tightly fixed on the tail tower, and the other end is connected to the pulley 30 on the head turret. It is necessary to adjust tension and lowering the non-dried cable.

Through the tensioning devices, each side of the bucket is connected to the tail and head cables. Each of the pull cables is wound on separate drums 31 and 32 of the winch. Head or tail traction ropes will mix the bucket and carriage in the direction of the tyuy or others} of that tower. A double-sided bucket can be loaded — gathering soil — and unloaded both during movements from the head tower to the tail tower and during the reverse course - from the tail tower to the head tower.

Both towers or masts can have the same height, since the carriage and the bucket have a forced movement by means of tow cables 16 and 17. If both towers have the same purpose — to load the buckets in the bunker and dumps of the same height — then they can have the same height. The carrier cable may be located on one gf rizont. Forcing the bucket to move but carrying the cable makes it possible to avoid cumbersome and expensive construction in the form of a very high head tower. The height of the tower depends entirely on the technological process of the work, such as the type of the mixing device and the height of the bunker or the height of the soil dump. In the presence of soil unloading at the tail and head towers in the case, the height of the blade (and towers) will be two times less compared to one-way unloading.

If the cable 17 is wound onto the winch drum 31, then along with the movement of the carriage the cable 19 will be pulled in, and at the same time the cable 20. The cable 20 will not follow the creamer 2U, the tooth of which will move sector 23 and flaps 25 The bucket 24 will occupy the position shown in FIG. 1 of the drawing, i.e., the flap 25 will be open and the bucket can pick up the ground during the movement of the rope 17, and the flap 24 will assume a vertical position and will serve as the back wall of the bucket.

The doors retain this position even at the time of the bucket for unloading. When the traction tail cable 16 is tightened, the flap 25 will take an upper horizontal position, and the flap 24 will lower and take the vertical position.

Stops are placed inside the bucket against which the flaps rest when they are in a vertical position for better resistance of the doors to the pressure of the ground. Bottoms of the bucket can have knives with teeth on both sides of the shaft to facilitate ground gathering. The slats to which the cables 19- / 5 are attached have two or three holes vertically to reinforce the cable 19-19 at different heights in order to regulate the bucking of the bucket into the ground. When winding on the winch drum of the cable 17, the bucket moves with the carriage to the head tower and unloads near it. When winding on the drum of the winch of the cable 16, the bucket moves towards the tail tower - and there it is unloaded.

The second variant of the double-sided bucket (Fig. 4) has freely suspended two-sided wall-flaps 24 and 25, freely rising and falling under the influence of its own weight or ground pressure during the filling of the bucket; for this reason, the rack is excluded and there is no need for cables, chains x 20-20. The free side walls of the bucket abut their ends in the bottom of the bucket and there is no need for side stops.

If at the time of unloading when the bucket overturns, the bottom flap drops to the end of the complete emptying of the bucket from the ground and a part of the soil remains in the bucket, then the inclined position of this gate ensures that the remaining soil drops out of the slope of the top of

head. Such a structure simplifies the device and completely ensures its normal operation.

Otherwise, the bucket structure of the second embodiment is no different from the first bucket and they work the same.
