Description

The invention of RELATED T5T is for transport engineering and can be used for transportation and sorting of timber (logs) in enterprises of the timber and woodworking industry.

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

FIG. 1 shows the proposed traverse, a general view with a section along the axis; in fig. 2 - the same, with a log; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - the moment of dumping the log from the traverse, general view; in fig. 5 is a node I in FIG. four.

The traverse for timber includes base 1, fastening of a traction body, for example, stirrup 2, supports made, for example, in the form of rollers 3. On the base 1, a device for fixing and orientation of timber is mounted, made in the form of pneumatic chambers 4 and 5, the shell of which can be made of reinforced rubber, polymer material, rubberized fabric, etc. The sheath of the pneumatic chambers 4 and 5 forms the bearing saddle surface 6. In addition, the pneumatic chambers 4 and 5 have clamps located in the shell in the zone of maximum pressure of the log, and representing elastic elements, for example corrugated plates 7, are connected at one end to base 1 (Fig. 3). Pneumatic chamber 4 is installed on base 1 without clearance relative to pneumatic chamber 5. The thickness of the shells of pneumatic chambers 4 and 5 decreases in the direction of dumping of timber or rollers 3 (Fig. 2 and 3), and the bearing saddle-shaped working surface of chambers 4 and 5 has protectors 8 and nzhpy 9 (fig. 5).

Traverse for timber works as follows.

Timber (assortments, logs) is supplied by a single piece feeder to the carrier saddle surface 6 traverses which move along the storage front on the rollers 3. When loading the log, the traverse and rollers 3 are not transferred to the base 1 by pneumatic chambers 4 and 5. When moving, the traverse with the log due to the fact that the pneumatic chambers 4 and 5 are displaced relative to each other (due to the elastic properties of the shells and the mounting of chambers 4 and 5 with the base by means of plates 7), and the saddle-shaped Surface 6 copies the surface of the log and the defects (Fig. 2). The log occupies an equilibrium position on the traverse and balances between the chambers 4 and 5 in the process of traversing the traverse without creating additional effort.

drive n; them to skew and wring traverse. In this case, the plates 7 ensure the retention of the log from spontaneous dropping from the crosshead.

 After issuing the command to dump the log into the corresponding forest accumulator, the resetter of this wood accumulator (Fig. 4) is activated, which acts on the log, moving it along the saddle-shaped bearing surface 6 of the traverse in the direction of the dump.

0 At the same time, the saddle carrier surface 6 due to the elastic properties of the casing of the pneumatic chambers 4 and 5 bends without exerting resistance to the ejector, which eliminates additional efforts from the side of the ejector to the base 1 and cat 5 and increases their durability. After rolling up a log with a saddle-shaped bearing surface 6, the pneumatic chambers 4 and 5 occupy the original shape (Fig. I). Constructive execution of the thickness difference between the walls of the shells of the pneumatic chambers 4 and 5 allows, during transportation of the log, to ensure its fixation on the traverse by reducing the possible vibrations that occur when the rollers overcome 3 irregularities of the guides along which

5 move (which is provided by the required wall thickness of the shells in the zone of maximum pressure generated by the log to the device for fixing and orientation of timber, to its saddle-shaped surface 6), and also to provide the necessary flexibility (elasticity) of the chambers in the direction of shedding the log. The treads 8 and the spikes 9 contribute to the improved adhesion of the transported log to the saddle-shaped bearing surface 6, regardless of the state of the log surface (bark moisture, icing, etc.), especially when starting off and stopping the crosshead. In addition, the spikes 9 provide for a clear roll on the saddle-shaped bearing surface 6 (no slippage) when dumping the log, thereby increasing the accuracy of dropping the log into the silo collector (when the log slides, there is a different speed of the ends of the log ends due to different (varying in wide limits) of friction coefficients

5 of the surfaces of the log and the material of the saddle-shaped bearing surface 6 and the scatter of the ends of the logs in the accumulator is reduced.

The proposed traverse (compared to the known ones) is reliable and durable due to the exclusion of the skew, which causes a polo traverse and a breakage of the traction organ. In addition, there are no additional shock loads on the supports and the base of the traverse when it is loaded with timber.
