Description

Phae.1 ///// A (/////// A

The invention relates to the transport machinery industry and can be used for the transportation of timber in enterprises of the forest and woodworking industry.

The purpose of the invention is to increase the reliability and durability of the traverse.

FIG. 1 shows a traverse for timber, a section along the axis; in fig. 2 shows section A-A in FIG. 1, type of traverse with two road wheels; in fig. 3 - the same, the execution of the traverse on the four support rollers; in fig. 4 - the same, traverse design on four track rollers and with additional support in the form of a skating rink.

The timber traverse includes a beam 1 with a bearing surface in the form of a saddle 2, a device for fastening beam 1 to a conveyor body consisting of stirrups 3, rollers 4 mounted by means of elastic elements, for example springs 5 on brackets of beam 1 on the axis x 6, the free ends of which are rigidly mounted in the upper part of the spring 5. The lower part of the springs 5 are supports 7 and 8 of sliding or rolling.

Traverse works as follows.

Timber materials (assortments, logs) are supplied by a single piece feeder to saddles 2 traverses, which are moved by means of a traction body along the storage front along two longitudinal guides on rollers 4. After the command to dump the timber into the corresponding accumulator is triggered, a dropping mechanism operates, which acts on the assortment, which is on the traverse, and overturns it in the forest storage facility. When the traverse is loaded, the assortment collides with the saddle 2 and the force arising in this case acts on the beam 1, which moves in the direction of the impact due to the deformation of the springs 5. Esl.

does not exceed the stiffness of the springs 5, then it is damped by the springs, and if it exceeds, by the interaction of additional supports 7 of the slide (or rolling 8) with the support surface (i.e., the longitudinal guides). During the movement, the traverse with large-sized timber of the spring 5 bends and the additional supports 7 (or 8) interact with the longitudinal guides, thereby removing the excessive load (load at which the rollers quickly wear) from the rollers. After dumping the timber into the timber accumulator, springs 5 occupy the original shape and remove additional supports from the interaction with the guides, since they create additional resistance to the movement of the traverse along the guides. During the transportation of the traverse non-cumbersome spring timber, the dynamic loads that occur when the rollers copy the surface of the guides (the curvature of the projections and cavities, as well as the obstacles in the form of chips, bark, sawdust, soil, etc.) the traverse body itself is prevented from fatigue damage.

In addition, when using traverse with four support rollers (Fig. 3), the springs provide independent movement of the rollers 4 in a vertical position

0 (due to the elasticity of the springs), which eliminates the traverse bias, spontaneous dumping of timber and ensures a uniform distribution of the load between all rollers 4.

To reduce the resistance created by the additional sliding support 7 when moving the crossbeam. timber, it can be equipped with a support roller - rollers 8 (Fig. 4).
