Description

The invention relates to cable skidding installations and can be used by the forest industry to develop forests on mountain slopes, in lowland and marshy conditions.

The aim of the invention is to increase the efficiency of the use of self-propelled drive power.

Fig. 1 shows a schematic diagram of the cable installation (the dashed line B shows the transport position of the pivoting rack); in fig. 2 — node 1 — in FIG. 1 (base, lower part of the mast), in FIG. 3 is a view along arrow A in FIG. ,; in fig. 4 - view along the arrow

8a to fig. 1 (turned).

The cable installation is mounted on a self-propelled chassis 1, for example, an MTZ-80 tractor, from whose power take-off shaft through a reversing gearbox 2, a propeller shaft 3, and an open gear train 4 and 5 of clutch 6 and 7, winding trash

9i ba, raban 10 — winding t of hoisting ropes 11. The drums 8 and 10 are located parallel to the longitudinal axis 12 of the tractor 1 and at the base 13 of the vertical part of the mast 14. The carrying cable 17 is wound through the polyspit 16 on the drum 15, located at the end of the turntable 19, connected by a hinge 20 with the vertical part of the mast 4. The turn of the rack 19 is performed by a hydraulic cylinder 21. The vertical mast 14 is supported when the mast is installed, the working position on the pad 22, which perceives the vertical component from s arising in the mast when working. The drum 15 for winding the carrying cable 17 is located at the front of the tractor perpendicular to its longitudinal axis 12 and connected to the frame of the tractor 1, and is driven from the hydraulic motor 23 via a worm gear 24 (Fig. 4). The cable 9 is driven through the block 25, across the axle at the end of the vertical part of the mast 14, and through the block 26 located at the end of the swivel arm 19s which is in the transport position (position I of FIG. 1) rests on bracket 27,

A carriage 28 with a cargo block 29 and an anvil 30 is hung on the supporting cable 17, and the cable 17 is connected to the rear support 31 of the stretched extension 32. Guiding blocks 33 serve for storing the hauling rope 9. 34. Controls: 35 - brake knobs, 36 - clutch pedal. Unloading platform 37 serves for stowing cargo. Ropes on drums 8 and 10 are laid using cable-laying 38 and 39 with a drive through chain transmission 40 from each drum 8 and 10. An additional or auxiliary drum 41 serves to tension the hens; through the chain hoist 16e, it can be connected to the drum 15 or be disconnected by a retainer (not shown), and its drive, like the drum 15, is carried out from the hydraulic motor 23.

The installation works as follows.

In transport position, channels 9 ;. 11 and 17 are wound on their drums, and the turntable 19 is in position B (Fig. 1), the Mobile cable installation is delivered under its own power to the developed cutting area. The weight of the cargo in the process of transporting the cargo is transferred to the carrier cable and it is made accordingly thicker, and the traction and the cargo-lifting trailer are thinner, the traction rope serves at the same time as the installation rope, i.e. it is used to install to the installation with the help of it: it is passed through the block 33 of the rear support 31, the supporting cable 1 7 3 is tightened, the swiveling post 19 is put B in the working position (Fig. 1), the braces are put 34 and the supporting cable 17 is pulled by means of the chain hoist 16, the carriage 28 is mounted on an unstuck rope 17 and connected to the haul and hoisting rope by known methods. By winding the cable 9, the carriage 28 is moved to the rear support 31 (to the load attachment point), the cargo is hooked, lifted, fixed in the carriage 28 and, turning on the reverse gear 2, lowered. At the same time, depending on the revolutions of the power take-off shaft (from the tractor's gas pedal), the load is lowered down to the unloading platform 37. Since the carriage lowering speed

27 is downwardly related to the speed of rotation of the power shaft, i.e. engine of the tractor, it is not necessary to use brakes for braking the traction drum, which are heated and often jam when braking.

The carriage, while reaching the stop 30, is unlocked, and the load is lowered "and the unloading platform 37, after the cargo is uncoupled and the hook is lifted from the cargo block 29, the carriage 28 is again moved upwards.

2145134

Dismantling the installation is as follows.

The carriage 28 is moved to the mast, 5 the cable 9 is uncoupled and wound onto the drum 8, the carrier cable 17 is uncoupled from the rear support and wound on the drum 15 with the help of a hydraulic motor 23, the straps 19 are removed transport position (dot-dotted line In Fig. 1) and move the installation to a new cutting area.
