Description

The invention relates to the mechanization of alloying and can be used in the logging industry. five

A device for launching bundles of timber is known, comprising a load trolley moving along an inclined track, with folding legs, to which the free ends of a rope passed through guide blocks mounted on the frame of the cart and attached to the middle part of the rope are attached cargo rope [1] . 15

A disadvantage of the known device is the lack of reliability.

The purpose of the invention is to increase the reliability of work.

This goal is achieved by the fact that a guide for a cargo rope is located on the frame of the trolley located in the central part of the rear-25th end of the trolley, while the cargo rope is equipped with a limiting stop that interacts with the rear end of the frame of the trolley when the folding legs are raised. In addition, a group of 30

The rope rope is attached to the rope of the racks by means of a clip with a roller.

FIG. 1 shows a schematic of the device, - a general view; in fig. 2 - the same plan view; in fig. 3 - section A — A in FIG. 2

The device contains a trolley 1, mounted on the track 2 (rails).

The cart consists of a frame 3, on which are mounted folding racks

4. On the frame 3 of the trolley, there are guide blocks 5, through which the rope 6 is passed, the free ends of which are attached to the uprights 4.

To the middle part of the rope 6 through the bracket with roller 7 attached cargo rope 8, which serves to move the trolley and passed through the guide 9, mounted on the rear end of the frame 3 of the trolley 1 coaxially with its longitudinal axis.

The cargo cable is also equipped with a limiting stop 10, which interacts with the rear end of the frame 3 of the trolley at the raised position of the folding struts 4.

To fix the load trolley to

the edge of the water, serves as a support device, made in this particular-. In this case, in the form of a rope 11, which goes around the drum 12, is mounted on the frame 3 of the carriage, the ends of which are fixed in the upper and lower points of the track 2.

The rope 11 is equipped with a clamping stop 13, interacting with the guide protrusion 14 of the frame 3 of the trolley 1.

Depending on the water level, this clamping lug 13 can be easily moved along the rope 11.

The device works as follows.

Trolley 1 is fed to the place of loading, where a bundle of timber is placed on it. When this rack 4 through the tension of the load rope 8 with a restrictive stop 10 occupy a vertical position relative to the frame of the truck and hold the immersed beam.

Then the trolley 1, braked winch (not shown) with a cargo cable 8 rolls down to the water on the track. When approaching the water edge, the cart, via the guide protrusion 14, cooperates with the clamping stop 13 and stops.

The cargo rope 8, continuing to unwind from the winch drum, weakens the tension of the rope 6, the pillars 4 under the action of its own weight and the beam impact on them are lowered, the load inertia slides off the cart and moves down the sloping path.

After the release of the trolley, the last winch begins to be lifted after the new bundle. At the same time, the cargo rope 8, under tension, acts on the Rope b, lifting the pillars 4, which at the moment of interaction of the restrictive stop 10 of the cargo rope with the rear end of the frame 3 of the trolley occupy the working vertical position. The cart begins to climb up the track for a new bundle of lumber. Then the cycle of work is repeated.

Claims (2)

Claim 1. A device for lowering bundles of timber, containing a trolley with folding legs moving along an inclined track, to which the free ends are attached, of a rope passed through guide blocks mounted on the frame of the trolley, and a cargo rope is attached to the middle part of the rope L and chakzas e with the fact that, in order to improve reliability, on the frame of the trolley is installed a guide for the cargo rope, located in the central part of the rear end of the trolley, while the cargo rope is equipped with It is an effective support interacting with the rear end of the trolley frame with the raised position of the folding racks. 2. Device pop. 1, characterized in that the cargo rope is attached to the rope racks by means of the bracket with a roller.
