Description

(54) VEHICLE FOR THE FORMATION AND TRANSPORTATION OF A PACKAGE OF LONG DIMENSIONAL CARGO,

Avoidance relates to the logging industry, namely, devices that ensure the formation and transportation of a pack of lengthy goods, predominantly pre-felled trees. A vehicle is known for forming and transporting a pack of lengthy goods containing conic, equipped at one end with a rack, and at the other -: g - articulated loading arm, driven by a hydraulic cylinder. The specified vehicle also includes a tie-in cable, with the ends secured to the loading arm and the conic strut, and connected to the base of the conic by the middle part. Machine loading is done by pre-laying the trees on. the loading lever using additional mechanisms, such as a pivoting arm mounted on a tractor, and transferring them to the rider by a power drive hydraulic cylinder, lever, and the clamp is due to a cable loop formed when the loading arm enters the conic stand 1 jack. its greater energy intensity (the need for a gripping manipulator for placing trees on the loading arm), as well as the imperfection of the cable clamping device, which does not provide the full load for the tractor. The closest to the invention is a vehicle for forming and transporting a pack of long loads,. containing a frame, a winch mounted on it with a cable-blocking system and. by means of a bogus turntable and an articulated jib boom made of articulated links mounted on a bunk of a conic rotatable in the plane of the latter (2. The disadvantages of this vehicle are the low reliability of clamping small packs of trees and the impossibility of unloading it to the side without loading The purpose of the invention is to improve vehicle performance. It is achieved that in a vehicle one of the cable blocks system is fixed by means of a vertical axis on the conic beam, the others through the horizontal axes respectively on the lifting boom and on the conic beam, while on the turntable between the first unit and the winch is mounted a cable stopper stocked through all the above blocks and the free end attached to the upper parts of a horseman stand opposite to said lifting boom.

FIG. 1 shows a schematic view of a vehicle from the rear at the moment of the capture of a pack of lengthy material to be loaded, general view; in fig. .2 .- the same, in the transport position; in fig. 3 is a section A-A in FIG. 2

The vehicle includes a self-propelled driver 1 with a turntable 2, on which a conic beam 3 is fixed. At one end of the beam 3, the stand 4 is rigidly mounted, and on the other, by means of the joint 5, an arrow 6 is mounted with a arm / and a maxillary gripper 8. For bringing the boom 6 of the arm 7 and the jaws of the gripper 8, the corresponding force cylinders 9, 10 and are installed. 11. Inside the maxillary gripper 8, cable semi-loops 12 are fixed, and cable 13 of the winch 14 through the deflecting unit 15 installed on the turntable 2 is stocked through the horizontal unit 16 fixed to the conic beam 3, then looped through the deflecting blocks 17 and 18 mounted to the beam 3 and the boom 6 in the plane of rotation of the latter and secured in the upper part of the support stand 4. The block 15 is provided with a stopper 19 of the cable 13.

The operation of the device during the loading, transporting and unloading of lengthy fuzz is carried out as follows. Self-propelled shaspsi suited to the butt part of a pre-formed pack of trees. The operator, controlling the hydraulic cylinders 9, 10 and And with the stopper 19 turned off and the drum of the winch 14 discontinued, lowers the previously opened maxillary grip 8 onto the pack.

Then, by means of cylinders 11, the jaws of the gripper 8 are closed and with the help of hydrocyldra 9 and 10, the com. Left part of the pack is transferred to the conic beam 3.

The installation of the bundle into the bunk drum of the winch 14 is disinhibited, therefore the cable 13 is placed on the beam 3 when the bundle is packed into the broomstick 3. After the bundle is placed with the stopper 19 of the cable 13 off, the winch 14, cable 13 is turned on, pulling through blocks 16, 17, 18 and 15, presses the trees in half loop 12, which ensures their reliable retention in the conic. After that, the stopper 19 is turned on, and the winch drum 14 is disinhibited and does not interfere with the rotation of the support beam 3 with a fixed load.

relatively shassi 1 when moving last.

When approaching the next bundle of trees, the hydraulic fixer 19 is turned off, the operator, first controlling the hydraulic cylinders 11, opens the jaws of the gripper 8, then using the hydraulic cylinders 9 and 10, removes the gripper from the beam and lowers it onto the bundle, the loading of which is carried out vehicle load.

The unloading of the device at the final point of transportation is carried out either by removing the load from the conic with the jaw gripper 8 or by pulling the cable 13 with the boom 6 raised and the arms 7. In the latter case, the cable 13, winding on the winch drum 14, lifts the conic Uchas, the cable current, and the trees roll on it past the support pole 4.

The application of the proposed vehicle as a loading and hauling equipment allows to improve its operational capabilities.
