Abstract

The invention relates to forestry equipment and can be used for group sawing of timber. The purpose of the invention is to increase reliability by providing clampless sawing. The installation comprises a maxillary gripper 1 with a sawing mechanism 2, hung on the hook 3 of a crane, and in pairs installed on the base 4 of the uprights 5 and 6. The uprights 5, 6 are equipped with guides in which the carriages are mounted resting on the springs. On the carriages between the respective posts 5 and 6, flexible crossbars are fixed. The height of the flexible crossbars from the base 4 in the uprights 6 is greater than that in the uprights 5. A bundle of whips 12 laid on flexible crossmembers between the uprights 5 and 6, under the action of its own weight, bends towards the movement of the saw mechanism 2. As the bundle of saws is sawn, its weight, arrival The racks on the crossmembers 6 are redistributed to the crossmembers of the uprights 5. Due to this, the carriages are raised with the crossbars in the uprights 6 and the carriages with the crossbars in the uprights 5 are lowered. The application of the proposed installation allows to increase the reliability of work when sawing up packs of logs by providing clampless sawing. 9 il.

guides in which carriages are mounted that rest on springs. On the carriages between the respective posts 5 and 6, flexible crossbars are fixed. The height of the flexible crossbars from the base 4 in the uprights 6 is greater than that in the uprights 5. A bundle of whips 12 laid on flexible crossbars between: the uprights 5 and 6, under the action of its own weight, bends towards the movement of the saw mechanism 2. As the bundle of sawn is sawn, its weight, coming on the crossmembers of the uprights 6, is redistributed to the crossmears of the uprights 5. Due to this, the carriages are raised with the crossbars in the uprights 6 and the carriages with the crossbars in the uprights 5 are lowered.

The agreement is related to forestry equipment and can be used for group sawing.

The purpose of the invention is to increase reliability by providing clampless sawing.

FIG. 1 shows the proposed installation, side view; in fig. 2 - the same, top view; in fig. 3 and 4 - sections A-L and BB, respectively, in FIG. 1 before sawing; in fig. 5, 6 - the same, in the process of sawing; in fig. 7 is a section bb of FIG. 2; in fig. 8 - section G-Y in FIG. one; in fig. 9 is a section d-d in fig. 8. I Installation for sawing packs of logs includes a jaw grip 1 with a sawing mechanism 2, a hook mounted 3 a crane, and mounted in pairs on the base 4 racks

5 and 6.

Racks 5, 6 are provided with guides 7, in which carriages 8 with rollers 9 are placed. Carriages 8 rest on holes 10. Flexible carriages 11 are fixed on carriages 8, Moreover, the height of flexible crossbars 11 from the base 4 decreases to both sides of the grip

I, i.e. the height of the flexible crossbars 11 between the uprights 6 is greater than the height of the flexible crossbars between the uprights 5; a pack of whips 12.

Installation for cutting packs of whips works as follows.

A pack of whips 12, captured by the jaw grip 1, is lowered between the uprights 5 and 6 on flexible crossbars

I1.The rope of the crane is lowered and due to the difference in height of the flexible crossbars 11 between the uprights 6 and 5, a pack of whips 12 under the action of its own weight and weight of the grip 1 completely compresses the springs 10 in the uprights

6 and bends to meet the movement of the saw mechanism 2. At the same time, the springs 10 of the uprights 5 load from the weight of the pack X. PISTOV 12 and the grip 1 practically or slightly (see Figs. 3, 4). Include saw mechanism 2, which is moving

down, alternately (starting from the top) saws the whips.

As the bundle 12 is cut, it is divided into three parts. The lower part (non-sawn) interacts with flexible cross-rams 11 racks 6, 5 and the load from the weight of this part and the weight of the gripper 1 falls on the crossbars 11 racks 6. The load from the two sawn off parts is redistributed between the cross-bars 11 respectively, the left relative to the capture of 1 racks 5 and 6 and the right racks 5 and 6. This causes a decrease in the load as the weight of sawn off parts on the crossbar 11 racks 6 increases and the load on the crossbars 11 racks 5 increases.

As a consequence, the crossbar 11 of the uprights 6 are raised together with the carriages 8 under the action of the springs 11, and the crossbars 11 of the uprights 5 are lowered. When this occurs, the opening zone is cut.

Application of the proposed installation

 allows you to increase the reliability of work when sawing blocks of logs by providing clampless sawing.
