Abstract

Field of application: logging industry. Essence: The rail of the cable-rail skidding system includes collapsible rails, two carriages, carriage cones are made upright, hand winches for collecting, fixing and moving a bundle of whips into the carriage. Novelty: rails for forming a rail the paths are prefabricated, for the primary removal of wood there are two self-immersed removable carriages with folding cones, adjustable by cable distance between them for different lengths s of transported whips, and a manual winch without a drive, loading of whips into carriages is carried out using a manual winch without a drive. Advantages: the efficiency of the cable-rail skidding installation due to the loading and moving of whips from the felling site to the place of primary removal. 6 ill.

Description

The utility model relates to forestry equipment and can be used in the forestry industry.

Cable railways have been widely used in various sectors of the national economy for the primary removal of wood from hard-to-reach cutting areas due to soil and ground conditions. They found the greatest application on skidding of wood on hilly ridges.

The construction of cable cars and railways used in the logging industry is given on page 137 in the book of N. N. Beloy and A. Prokhorenko. "Rope forest transport installations." - M .: Forest industry. 1964 .-- 300 s. Cableways consist of a railroad, a cart, a drive.

Cableways have the following advantages over other types of skidding: low weight of the structure and low specific pressure on the ground, which makes it possible to use on weakly bearing soils.

Disadvantages of cableways: lack of mobility (rail is not collapsible).

The main advantages of cableways are achieved by low weight and specific pressure on the ground, which allows them to be used on weakly bearing soils.

The main disadvantages of the cable rail systems of traditional design are caused by the fact that the rail track is not collapsible, the carts do not allow logging of whips of different lengths.

It is necessary to create a new type of cable rail systems that would preserve the advantages of traditional cable cars and railways (low specific weight of the structure), but would not have their drawbacks (low mobility, the inability to adjust the length of transported whips).

The task set above can be accomplished if modernization of prefabricated trolleys is carried out, i.e. install devices on two removable carts (in the form of cones of the winches tilting to both sides) for loading trees (whips) and skidding in a completely submerged position.

In the utility model patent No. 113917 Cable-rail skidder (publ. March 10, 2012 Bull. No. 7, patent holders: Grigoryev I.V., Svoykin F.V., Nikiforova A.I., Grigoryeva O.I., Khakina AM) describes the design of the cable-rail skidder installation, including the rail track, cable equipment, winch, characterized in that it is mobile, placed on a freight platform of a motor vehicle and contains a gantry mounted on a freight platform and a removable hopper platform, in which contains a pack of mod beehive rail for a collapsible rail, a removable carriage (trolley), stationary and mobile winches for moving the carriage (trolley), as well as for collecting and disassembling the rail track and rope equipment. This model is taken as a prototype. When using cable-rail skidders, the mobility of the structure increases.

The disadvantage of this model is the method of skidding of whips from the place of felling to the place of completion of primary transport in a semi-submerged position.

The task the utility model is aimed at is loading and skidding logs from the place of felling to the place where the primary haulage ends.

This is achieved by the fact that not one, but two removable trolleys are installed on a collapsible rail track, with devices (in the form of cones and winches tilting to both sides) for loading whips (trees) and skidding in a completely submerged position, and the distance between the trolleys skidding of whips (trees) of different lengths is regulated by changing the length of the rope connecting the carts. The carts are pulled apart to the length of the whip (tree), the cones of the cart are reclined, the whips are captured by the winch, then the process of dragging the whips to the carts, and the whips are immersed in the cart.

In FIG. 1 shows a general view of a rail road; in FIG. 2 - rear view; in FIG. 3 - operating position of the device; in FIG. 4 - a set of packs; in FIG. 5 - transport position of the installation (front view); in FIG. 6. - transport position of the installation (side view).

A device for collecting wood of a cable-rail skidder includes collapsible rails 1, two trolleys 2 are moved along them, the cones of the trolleys 3 are folding, which allows the winch 4 to collect, fix and raise a pack of whips onto the trolley.

The proposed utility model is arranged as follows. On a collapsible cableway 1, two trolleys 2 are driven by winches. Carts stop at the place of collection of a bundle of whips (trees), the conics 3 are mechanically reclined from the side of the collection of bundles, the bundle is set by hooking the whips with a winch 4. The conics 4 are fixed in the transport position and the carts with the bundle of whips to the unloading place.

The proposed design allows to increase the efficiency of the cable-rail skidder due to the efficient mechanism of loading and unloading whips (trees).

Claims (2)

A device for collecting wood from a cable-rail skidder, including a rail track and a device for loading and unloading whips or trees, characterized in that two removable carts are provided for skidding the wood in the submerged position with devices in the form of cones and winches tilting to both sides for loading whips or trees, and the distance between the carts for skidding whips or trees of different lengths is controlled by changing the length of the rope connecting the carts.
