Description

one

The invention relates to cable track installations and may be used in the forest industry to develop forests on mountain slopes.

Known cable car installation, including a self-propelled chassis equipped with a two-drum winch, dozer blade and a mast rotatable in the longitudinal vertical plane, have a rear support and a system of blocks with a go-carrying rope passed through them.

However, installations of this design do not provide increased reliability

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

For this purpose, the installation is equipped with a device for stabilizing the tension of the go-carrying rope, made in the form of a hydraulic cylinder fixed on the rear support, on the rod of which deflecting blocks are installed with the go-bearing cable passed through them on the winch drums.

FIG. 1 shows the proposed cable skidder, general view; in fig. 2 - diagram of the drive installation.

The ropeway skidder contains a self-propelled chassis 7, dozer blade 2, mast 3, drive 4, a go-carrier rope 5, a transport carriage 6 and a rear unit 7.

The drive 4 consists of a traction drum 8, a return drum 9, a hydraulic cylinder 10 for stabilizing the tension, is reinforced on the rear support //, a tension carriage with blocks 12 and a deflection of the lower blocks 3. The drums 8, 9 are identical in design and size, each They contain a ratchet wheel 14, which is rigidly connected to the drum, ratchet paws 15, Planted on an axle and rigidly connected to the drum gear, which sits on its shaft on bearings.

The cable trailer operates as follows.

After installation of the rear block 7 tons of govolight rope 5, carriage b and transfer of the dozer blade 2 and the mast 3 to the working position, the pull of the gobo-carrying rope is pulled back by the return drum 9 while braking the traction drum 8 and retracting the hydraulic cylinder 10 to stabilize the tension l eni The drum 9 is transmitted from the tractor engine through the tractor's reverse transfer case, the tractor winch gearbox, the pinion gear 16 and the gear wheel of the drum 8, which rotates with the ratchet pawl 15 relative to the ratchet wheel 14 and transfers the gear of the drum 9 to the wheel the turn of torque through the ratchet dogs ts ratchet wheel connected to the drum.

Upon reaching the required tension (lifting the carriage), the drive is not stopped, brake the drum 8, and the carriage is fed into the cutting area. At the beginning of idling on the return drum, the rope is wound on the lower layer of the winding, and on the draft drum it is wound from the top layer of the winding, as a result more cable is wound on the traction drum than it is wound on the return one. This difference in length, as it is increased, is compensated by the extension of the rod of the hydraulic cylinder 10 connected to the tension carriage. When aligning the diameters of the winding of a go-carrying rope onto the drums, the winding and winding speeds are also equalized, therefore the cylinder of the hydraulic cylinder is stationary at this moment. The rod is drawn in when the transport carriage is fed further than two-thirds of the length of the cutting area, when the return drum 9 has the rope laid on the upper layer of winding and on the draft drum 8 on the lower elephant.

The rope and carriage are lowered to the ground by one of the drums when the other drum is braked, the ratchets of which are disconnected at this time (the ratchets are raised).

The collection and lifting of the cart is made by the tension of the system by the traction drum while the return drum is braked.

During transportation of the cart which starts from the moment of retarding of the return drum, the rod of the hydraulic cylinder 10 is advanced, thus maintaining the necessary tension in the system, i.e. the operation of the hydraulic cylinders is performed B in the same sequence as during idling. After the load is lowered and uncoupled at the storage site, the cycle is repeated.

Subject N o d e b e

A ropeway skidder includes a self-propelled chassis equipped with a double drum winch, a dozer blade and a mast rotatable in the longitudinal vertical plane having a rear support and a system of blocks with a carrying cable that passes through them, so that, with the aim of new reliability of work the installation is equipped with a device for stabilizing the tension of a go-carrying rope, made in the form of a hydrocylnndr mounted on the rear support, on the rod of which deflecting blocks with a missing gear are installed ithout them so govo-bearing rope, zapasovannym winch drum.
